Description

[0001] The present invention relates to a profiled building component intended to be mounted at the outside of a structure, e.g. in the shape of an outer wall, roof or inner wall structure, comprising an outer wall part, and inner part and an intermediate connecting plate part, said outer plate part and inner part being at an angle to said connecting plate part and extending in the same direction or opposite directions, with perforations being made in said connecting plate part and said outer plate part being arranged to connect to an outer plate part of a subsequent building component.

[0002] A similar building component is described in not prepublished application NL-A-1024543 in the name of applicant. With this earlier building component the inner part comprises an innner plate part extending up to or just beyond the beginning of the inner plate part of a subsequent building component. With the present building component, the inner part is a fastening part for fastening the building component to a structure, said fastening part being further designed to fasten or couple at least one finishing plate to it and/or being designed for providing support and/or connection to at least one finishing plate or other way of finishing. The outer plate part and connecting plate part of the present building component correspond to the outer plate part and connecting plate part of the building component according to NL-A-1024543 as far as not described otherwise in the following.

[0003] Thus, the present building component obtains a width which is almost equal to the construction width, yielding a building component which is easier to handle. With building components to be mounted horizontally, said construction width is the construction height. Like with said earlier building component, the outer plate parts and finishing plates provide for a continuous structure providing the required strength and stiffness to the subsequent building components. The finishing plates can be carried out in any desired form, in which one can think of plaster board, plywood or plastic plate. By continuing and coupling said finishing plates it is possible to insulate the conductive metal connecting plate parts from the inner conditions. A finish in the shape of a continuous foil is also one of the possibilities.

[0004] According to a further elaboration it is provided for, that for fastening and/or supporting and/or connecting at least one finishing plate in said fastening part or in the transition between connecting plate part and fastening part, a profile has been provided. Here, a finishing plate can come to bear on the connecting plate part and abut the connecting part or be clamped in or behind a U-shaped profile. Said profile is executed such that the finishing plates of subsequent building components can be received in one plane.

[0005] Instead of a profile in fastening part and connecting plate part one can also provide for a separately profiled auxiliary part which is mounted against the fastening part at the outside, that is, at the side facing the inside of the structure. This separately profiled auxiliary part is connected/fastened to the fastening part where said fastening part would abut the structure and be secured to it. There, said fastening means for the building component can project through said separately profiled auxiliary part. It is also possible to fasten said separately profiled auxiliary part to said connecting part in another way, in which it is not necessary that the fastening means for the building component project through the separately profiled auxiliary part.

[0006] According to a preferred embodiment it is provided for, that a body comprising an insulating material is mounted inside the building component. A similar insulating body can be mounted in the building component during construction or at an earlier stage preceding construction. According to a further elaboration the insulating body is then fixedly connected to at least one plate part of the building component. This is at least against the inner side of the outer plate part by which the largest possible strength and stiffness can be effected.

[0007] According to a further elaboration, the finishing plate or foil can also be fixedly connected to the insulating body. With these features, it is achieved that a taught, non-deforming outer plate part can be realized even when using thin plate material. By further providing longitudinally extending ribs, bending-through of said outer plate part can be almost completely excluded. These ribs also provide for transfer of forces in bridging direction to the columns, thereby reducing the load on other portions of said component. This makes it possible to provide extra large perforations in the connecting plate parts, for example. Further, it can be provided for, that said insulating body and/or the finishing plate has been fixedly mounted against at least a portion of the connecting plate part and/or the fastening part.

[0008] A particular embodiment is the one in which insulating foam in liquid form is inserted into the component and is subsequently covered and trapped by means of a finishing plate wherupon, if necessary, the insulation is cured in an oven. Another type of insulating material may already have been fastened to the finishing plate.

[0009] Preferably, the body of an insulating material and a finishing plate fixedly connected to it is also fixedly connected to a portion of said connecting plate part as a result of which a stiffening of said connecting plate per se and of the angular connection of outer plate part and connecting plate part are established.

[0010] Preferably, the insulation material and a finishing plate fixedly connected to it are mounted against said building component beforehand, so that this need not be done under mostly difficult circumstances at the building site. However, this does not mean that the same result could not be achieved in case of a separate supply of building components and insulating material and a finishing plate fixedly connected to it, which are mutually connected during construction.

[0011] According to another elaboration it is provided for, that the connecting plate part is provided with at least one turn and preferably that one or more turns have been provided spaced from the transition between connecting plate part and outer plate part. Such a turn provides, or such turns provide, a considerable increase in stiffness of said connecting plate part, due to which a better engagement of the insulating body on the connecting plate part can be effected and greater stiffness of the building component can be achieved.

[0012] According to a further elaboration it is provided for that the connecting plate part comprises a first part and a second part, said first and second parts extending in longitudinal direction of the building component and said first and second parts being fixedly coupled to one another at a turn or coupling.

[0013] Such a turn can e.g. have an angle profile or U-shaped profile. However, such turns can also be established by having two plate parts, in which a first plate part comprises an outer plate part and a portion of a connecting plate part and a second plate part comprises a finishing plate and also a portion of said connecting plate part, engage one another with a turn or a coupling. The coupling can be established by a mechanical fastening, clamping, welding, glueing, or other suitable fastening method. An insulation can be arranged between the coupled parts as a result of which a thermal bridge can be effectively prevented. A further advantage is that various materials, material thicknesses or material qualities can be employed or that finishing plate and outer plate part can be provided with different coatings.

[0014] The connecting plate part contains perforations for reducing a thermal bridge between outer plate part and finishing plate as much as possible. According to the invention, an embodiment provides for round or almost round perforations and another embodiment provides for elongate perforations. In the embodiment in which the perforations in the connecting part are of elongate shape, they extend in longitudinal direction of the building component. In both embodiments, the perforations are arranged offset to one another in two or more parallel rows. Preferably, it is provided for, that the distance between subsequent perforations has been chosen such that an approximately continuous path is formed in at least one direction obliquely to the longitudinal direction. These paths extending diagonally or oblique to the longitudinal direction of the building component perform the function of pull rods as a result of which the weakening involved in the perforations can be kept to a minimum.

[0015] By the mutual offset of the perforations, the way from the outside to the inside is also considerably longer than with one single straight connection, by which a thermal bridge can be kept limited as much as possible. According to a further elaboration it is provided for, that at one or both outer ends and/or an intermediate portion of said connecting plate part, across a limited distance the number of perforations and/or their size is reduced, or that the perforations are completely omitted. By this feature, the loads can be transferred more uniformly to the structure said building components are fastened to. Such a reduction or complete omission of perforations is e.g. also possible at half the span, across a certain length or at any other position. Instead of this feature or as addition to it, further fastening means and/or supporting means can be provided, in which said further means can be carried out in metal or any other material suitable to this end. Finally, overlapping (a portion of) the connecting plate part, provided with a reinforcement or otherwise, can improve this load transfer.

[0016] The perforations indicated above can be provided between said fastening part and a first turn or coupling or between the outer plate part and a first turn or coupling. Further perforations having another ratio between length and width can be provided at the opposite side or coupling. According to a preferred embodiment, first-mentioned perforations are provided between the fastening part and a first turn or coupling, and the further perforations at the opposite side of the first turn or coupling. According to a further elaboration, the two rows of further perforations have been provided between the outer plate part and a first turn or coupling, the further perforations comprising at least two further rows.

[0017] According to a preferred embodiment, the ratio between length and width of the further perforations is greater than the ratio between length and width of first-mentioned perforations. The distance between the subsequent further perforations in a row is smaller or relatively smaller than the distance between first-mentioned perforations.

[0018] The stiffness of said building component can be guaranteed without any problems, if one chooses one single turn in this embodiment. The weakening by the larger surface of the further perforations in relation to the surface of the connecting plate part in which they are provided, can be prevented to a sufficient degree by the fixed connection of the insulating body with the outer plate part and the connection or engagement thereof with said connecting plate part and/or the turn provided therein.

[0019] A first building component is securely fastened to the structure behind it by the fastening part, whereupon an overlapping portion of a subsequent building component is mounted against the outer side of the outer plate part beneath it by fastening means, such as e.g. screws. According to another elaboration, the connecting plate part and/or the fastening part is provided with a turn or turns so that the finishing plate connected to the insulation is fitted and held in it or will be fitted and trapped between this turn or these turns and the structure behind it. This causes subsequent building components to create a stiff Z-shape, to which tightly enclosed insulation body and finishing plate contribute to an important degree. There, the turn or turns in the connecting plate part and/or fastening part support insulation and finishing plate and largely prevent or limit the subsequent building components from displacement square to the plane, distortion or bending.

[0020] In the situation in which the finishing plate is fitted and enclosed between said fastening part and the structure behind it, there's no longer any direct contact between the metal connecting plate part plus fastening part and the inner space. Due to this additional insulation by the - in this case - non-metal finishing plate on this point, the performance regarding insulation value and fire resistance are enhanced.

[0021] According to the invention it is provided for that at least one of the outer ends of the building component has adaptations for having building components in rows and colums being square to them properly connect, this mainly concerning the points where four building components meet.

[0022] According to a first elaboration to this end it is provided for, that at at least one outer end of a building component the finishing plate and/or the outer plate part extend beyond that outer end of the building component. With a building component having the outer plate part projecting at one side, this will come to lie across the corresponding part of a subsequent building component in the row and the connecting plate parts and the finishing plates will come to abut. If the finishing plate extends past the building component, it will end in an equal distance at the other end in front of the building component. A proper sealing remains guaranteed by proper connection of the insulation bodies in subsequent building components.

[0023] It is also possible to have parts of the building components project symmetrically at both ends, in which according to another elaboration of the invention it is provided for, that at one outer end, a receiving space is provided between the inner side of an outer plate part and/or the bottom side (of a portion) of the connecting plate part and the insulation body mounted against it for receiving the portion of an outer plate of a subsequent building component therein. Finally, it is possible that (a portion of) the connecting plate too projects past the outer end.

[0024] An important advantage of the building component according to the invention is that the construction can take place in subsequent vertical or slanting columns which can be carried out completely from the bottom to the top before starting on the subsequent column. Thus, it is not necessary to provide a complete row in horizontal direction first, before one can start on a row situated higher. This goes for both the building components having overlapping parts and the building components which are connected by a coupling component.

[0025] Further, for having subsequent building components connect to one another, additional features are provided, which can be applied separately or in combination, including:

• that the finishing plate, the outer plate part, the fastening part and/or the connecting plate part or a portion thereof project, at least at one outer end of the building component, beyond that outer end of said building component;
• that at opposite outer ends the outer plate part extends across an equal distance past the outer ends, with a portion of said connecting plate part extending across said distance or not;
• that at least at one of both outer ends a receiving space is provided between the inner side of an outer plate part and the insulating body mounted against it for receiving therein a portion of an outer plate of a subsequent building component extending beyond the outer end of said subsequent building component;
• that the outer plate part has at opposite sides been provided with a connecting plate part and a fastening part connecting to it, said fastening parts further being carried out for enabling fastening or coupling at least one finishing plate to it, and/or are carried out for offering support and/or connection to at least one finishing plate;
• that the outer plate part has a continuous part at its bottom side, which continuous part in case of subsequent mounted building components extends beyond the outer plate part of a preceding building component.

[0026] For taking up forces, locally, e.g. at bearing points or halfway across the span, the percentage or size of the perforations can be reduced or even be completely omitted across a certain distance. Additional supports, in metal or otherwise, and/or fastenings can also be provided there. Another form of such an additionel reinforcement is carrying out the longitudinally connecting components in overlapping fashion at the supports.
When employing such an overlap, portions of the outer plate part, of the connecting plate part and/or of the reinforcements incorporated in it, and/or of the fastening part may have been removed in straight fashion or under an angle in order to prevent a stacking of plate parts which is too high and/or to facilitate fastening the components concerned. It is also possible that portions of these plate parts extend straight or at an angle past the bearing point and/or the end of this overlap.

[0027] Through said overlap and coupling through fastening means between adjacent components in the (outermost) corners of this overlap, the adjacent components can be coupled on moment-tight. There this fastening can take place in zones without perforations present for this purpose.

[0028] In order to make the moment-tight coupling achieved in this way sufficiently strong and rigid, the fastening part and possibly the connecting plate part or a portion thereof can be provided with additional turns and/or material cross-sections locally or across the full component length.

[0029] The invention is further explained by way of the examples given in the drawing, in which:

figs. 11A-B show a variation of an elaboration of the invention with two connecting plate parts and two fastening parts. This yields a building component having more or less, at least seen from the outside, the appearance of a sandwich panel;

fig. 12 illustrates a cross-section of a building component transverse to the longitudinal direction;

figs. 13A-D illustrate a blank and a number of cross-sections of a building component, respectively; and

figs. 14A-E illustrate the connection of four building components at a column, as well as a number of cross-sections thereof.

[0030] Fig. 1A illustrates a building component 1 having a finishing plate 2, a fastening part 3, a connecting plate part 4 and an outer plate part 5. An insulation body 6 is mounted against the inner side of outer plate part 5 and fixedly connected to it. Preferably, insulation body 6 is also connected to fastening plate part 4 or a portion of fastening plate part 4. Insulation body 6 is fixedly connected to finishing plate 2. Preferably, connecting plate part 4 is provided with turns 7. Here, fastening part 3 is designed such, that it encloses finishing plate 2 of the component and keeps it in place and also covers a portion of the finishing plate at the inside of the adjacent building component. Fastening part 3 can be provided with additional sealings 8, 8' additionally sealing the connection between this part and finishing plate 2.

[0031] Fig. 1B illustrates the same building component in which an additional turn 9 is provided at the inner side in connecting plate part 4, into and behind which, after mounting, the finishing plate 2 of the subsequent component fits and falls, if it extends across some distance past the insulation.

[0032] Fig. 1C illustrates the same building component in which at the inner side finishing plate 2 does not only cover insulation body 6 but (partly) fastening 3 as well by taking a greater thickness of insulation body 6 and by having the finishing plate 2 offset or project in relation to insulating body 6. An additional sealing 8 may be incorporated between this finishing plate 2 and fastening part 3.

[0033] The special aspect of this variation is that no metal parts will be visible from the inside and thus one will get the impression of e.g. a stone-/plaster-like building component instead of a metal building component. Furthermore, the thermal bridge action at the connecting plate part and fastening plate part is reduced even more and the fire-resistance is increased further.

[0034] Finally, fig. 1D illustrates the same building component in which finishing plate 2 at the inner side has been omitted. This component can e.g. be moutned in front of and on a closed structure behind it.

[0035] Fig. 2 illustrates a perspective view of a building component 1 in which rows of perforations 12, 14 have been provided in the parts 10, 11 situated at both sides of the turn 9 in connecting plate part 3. The individual perforations 12 have been provided such that the spacings between mutually offset perforations in subsequent rows are located on an almost continous strip of material. Thus, the weakening of the connecting plate part is kept as limited as possible. The effect of the perforations is that the thermal bridge formed by connecting plate part 3 is considerably reduced due to the long way from the outside to the inside.

[0036] Here, it can further be provided for

• that a water vapour proof covering is provided across the perforations in the connecting plate part, said water vapour proof covering comprising e.g. a self-adhesive foil;
• that the angle of the connecting plate part in relation to the fastening part and the outer plate part has been chosen such that in case of a building component fastened to a structure, the connecting plate part slopes obliquely downwards;
• that a relief groove has been formed in an outer plate part in the portion that in case of subsequently mounted building components ends at the connecting plate part of a previously mounted building component; and
• that the fastening part can be fastened to the structure located behind it and is accessible from the outside, before the next building component to be fastened is mounted.

[0037] Figs. 3A-D illustrates the coupling of three building components according to the invention 1, 1' and 1" with four possible embodiments of finishing plates 2 with the fastening parts 3, 3' and their fastening to the structure 4 behind it. The dimensions of this fastening part 3,3' have been chosen such that it offers sufficient fastening surface so that fastening 3 can be easily provided and is easily accessible, before the next building component is mounted.

[0038] Fig. 3A illustrates the variation according to fig. 1A. The view from the inside is determined by the finishing plates 2, 2' and 2" and by the fastening parts 3, 3' and 3" located between them.

[0039] Fig. 3B illustrates the variation according to fig. 1B. The view from the inside is determined by the finising plates 2, 2' and 2" and by the fastening parts 3, 3' and 3" located between them.

[0040] Fig. 3C s the variation of the embodiment according to this invention of fig. 1C. The view from the inside is determined by the finishing plates 2, 2' and 2".

[0041] Fig. 3D shows a variation of the embodiment according to fig. 1D, in which the finishing plates have been omitted. Such a finishing can e.g. be mounted at the outer side of an already existing closed outer wall finishing 15.

[0042] Fig. 4 illustrates an enlargement of the variation according to fig. 1D. Here, turn 9 in connecting plate part 4 fits exactly into recess 16 of insulating body 6 and thus also prevents (in case of a lacking finishing plate that can be clamped) displacement c.q. bending of the building component 1 as a consequence of the thus established coupling to the connecting identical building component fixed by means of fastening part 3.

[0043] Figs. 5A-B illustrate a variation, including ways of fastening and coupling, of the building component according to the invention, in which there are two connecting plate parts and two fastening parts per building component.

[0044] The building component 1 according to fig. 5A comprises an outer plate part 5, two connecting plate parts 4 and 4', two fastening parts 3 and 3', insulating body 6 and finishing plate 2. The sealings 8 and 8' can be added between this finishing plate and fastening parts 3 and 3'.

[0045] Fig. 5B illustrates the ways of coupling and fastening of the building components according to this variation. Here, the outer plate parts 5 and 5' have been designed such, that they connect to one another without the effect that this locally results in the building components projecting outwards and still a waterproof sealing of joint 17 is achieved. This connection and sealing can also be designed such that the turn in outer plate part 5' is partly or completely filled with insulating material, e.g. by means of a foaming process.

[0046] Fastening part 3 of building component 1 has first been secured to the rear structure 15 with fastening 16. Subsequently, building component 1' is clamped behind and into fastening part 3 by means of fastening part 3' and thus fixed without requiring an additional fastening at this side of building component 1'.

[0047] Figs. 6A-D illustrate four variations of said fastening part and the mutual connections between finishing plates. Fig. 6A illustrates the connection concerned according to the variation given in fig. 1B.

[0048] Fastening 16 extending through fastening part 3 fastens building component 1 at the rear structure 15. Fastening 16 can be a screw or a tacking nail or any other suitable fastening means. Fastening part 3 is designed such, that it abuts the rear structure 15 across a sufficient width, that it offers sufficient strength and rigidity together with connecting plate part 4 and a portion of the connecting outer plate part in order to be able to span the centre-to-centre distances between rear structure parts 15, that it provides enough space to at least two fastening means 16 per contact between this fastening part and the rear structure and in such a way that these fastening(s) can be easily mounted from the outside before building component 1' is positioned.

[0049] After the positioning of building component 1, turn 9 in fastening part 3 of building component 1' comprises finishing plate 2'. This causes said building component 1' to be clamped behind component 1 and be fixed by means of its finishing plate. Turn 7 in fastening part 3 of building component 1 comprises finishing plate 2 of this building component 1 so that a permanently neat and tight connection is achieved which also accommodates additional sealing 8. After the positioning of building component 1', turn 7' performs the same function with respect to the connection to the finishing plate 2' and sealing 8'.

[0050] Fig. 6B illustrates a variation according to the further elaboration according to fig. 6A, in which fastening part 3 after positioning, except at the rear structure, is covered from within by means of covering profile 18 and is thus hidden from view from within. This profile can be manufactured of plastic or any other material in a colour corresponding to the finishing plates or in a different colour.

[0051] Fig. 6C illustrates a further explanation according to the variation given in fig. 1C. Fastening 16 through fastening part 3 fastens building component 1 to the rear structure 15. Fastening 16 will be a screw or any other fastening means. When using a screw, it can be designed such, that it will get stuck by means of a thickened portion 19 against the rear structure 15 before the screw will have been fully tightened and before a force transfer contact will be established between fastening 16 and inner plate parts 2 and/or 2¹. This in order to prevent these finishing plates from getting under load of compressive and/or tensile forces and consequently getting damaged when tightening fastening 16 or when loads act on building components 1 and 1¹.

[0052] Fastening part 3 is designed such that through said finishing plates 2 and 2¹, it contacts rear structure 15 across a width that suffices to provide sufficient strength and stiffness together with connecting plate 4 and a portion of connecting outer plate part to be able to span the centre-to-centre distance between the rear structure parts 15, that this offers enough space to at least two fastening means 16 per contact between this fastening part and the rear structure and in such a way that these fastenings can be easily mounted from the outside before the next building component 1' is posit-ioned. Furthermore, fastening part 3 is of such width that finishing plate 2¹ is clamped behind it, and at the fastening between said fastening part and rear structure 15.

[0053] In this location finishing plate 2 too is clamped between this part and rear structure. Finally, it forms a supporting and fastening surface for a possible additional sealing 8. This additional sealing can have adhering properties causing inner plate parts 2 and 2¹ to be kept in place even better.

[0054] Fig. 6C illustrates a further elaboration according to this variation in which the connection between said finishhing plates afterwards and from the inside is finished almost invisibly through e.g. armour mat 20 and finishing layer 21 to be applied across the entire inside.

[0055] Fig. 6D illustrates a further elaboration according to the variation of fig. 6C in which the connection between said finishing plates in which the connection between said finishing plates from the outside or afterwards from the insides are finished by means of profile 22. This profile can be of plastic or any other suitable material in some dimensions and colour and e.g. by means of pressing can be applied between the finishing plates 2 and 2¹. Such a sealing can have additional sealing properties and avoids the risk of damaging the finishing plates at the connection. Such a profile or another type of profile can also be used at the vertical connections.

[0056] Figs. 7A-D illustrate yet four variations of the fastening part and the mutual connections between the finishing plates. Fig. 7A shows an additional turn 23 in fastening part 3. This turn not only allows for fixedly connecting finishing plate 2 through insulating material 6 to one or more of the plate parts of the building component, but also for fixedly connecting it at this turn directly to said fastening part 3.

[0057] Fig. 7B shows a variation in which the finishing plates 2 and 2¹ do not extend beyond insulating material 6 and 6' and there is still an inner view without metal parts. Finishing plate 2¹ ends at a distance from outer end 6 to offer space to fastenings 16. These will already have been mounted before building component 1' is positioned. In this way, a relatively wide seam 24 is produced, which is covered and sealed by a likewise relatively wide profile 22. This profile should be interrupted at the fastenings 16.

[0058] Fig. 7C shows another variation, in which the finishing plates 2 and 2¹ do not extend past insulation material 6 and 6¹, respectively, and still there is an inner view without metal parts. Here, both finishing plate 2 and finishing plate 2¹ end in alignment with the outer end of insulating material 6 and 6¹, respectively. With this variation it is necessary that small incisions, cuts, or the like are provided in plate 2¹ of building component 1' in the line of fastenings 16, preceding the positioning to provide space for fastenings 16 already mounted of building component 1 when positioning this building component 1'. By providing a space between finishing plate 2' and the insulation 6' there is room for fastening part 3.

[0059] Fig. 7D illustrates another elaboration according to the variation of fig. 7C in which connecting plate part 4 and the connecting fastening part 3 end at a distance from finishing plates 2 and 2¹ and thus also at a greater distance from rear structure 15. Since insulating material 6¹ between fastening part 3 and finishing plate 2¹ extends to the outer end of building component 1' and by providing said insulating material with perforation 25, the space thus created between fastening part and finishing plate c.q. rear structure is fully filled with insulation, as a result of which the thermal bridge action of the connecting plate part and fastening part is reduced further. With this variation, it is required that small incisions, cuts, or the like are provided in plate 2¹ and insulating material 6¹ of building component 1' in the line of fastenings 16, preceding the positioning to provide space for arranged fastenings 16 of building component 1 when positioning this building component 1'. Since now the building components can more or less start hanging from fastenings 16 and the moment arm of the forces occurring with it is relatively large, it may be necessary to provide the building components with additional support at a number of fastening points at the rear structure, e.g. by means of profile 26.

[0060] Fig. 8 illustrates an inner view of the building components 1 employed according to this invention in an outer wall structure. Here, it concerns the embodiment according to fig. 1A or 1B. The building components are fastened between and at said columns 15 horizontally and from the outside, said building components spanning the distance between said columns and transferring their loads to them. Visible from the inside are the finishing plates 2 and the metal fastening parts 3.

[0061] Fig. 9 shows an inner view of the building components 1 according to the invention employed in an outer wall structure. This concerns the embodiment according to fig. 1C. Here, the building components are fastened between and at said columns 15 horizontally and from the outside, said building components spanning the distance between said columns and transferring their loads to them. Visible from the inside are the finishing plates 2. Horizontal connections 26 between the finishing plates of connecting building components can be finished from the outside with a profile during mounting, or afterwards be finished from the inside with a profile or with a finishing strip and/or layer.

[0062] When the finishing plates are not offset in horizontal direction or project in relation to the connecting portions of the building component concerned, the vertical connections 27 between the finishing plates will be located behind the columns 15 and thus can not be finished from within as such. Although the columns then basically hide these connections from view from within, it may be desired or necessary, e.g. from the viewpoint of draught and condensation, to finish these connections 27 afterwards. By offsetting the inner plate parts 2 in horizontal direction in relation to the remainder of the building component or having them project across a distance which is greater than half the column width, the vertical connections 27 will end up next to the columns and can then be finished from within as such.

[0063] Figs. 10A-B illustrate a variation of connecting plate part 4 and fastening part 3 allowing for addition of a second finishing plate without additional fastening or coupling work. Fig. 10A illustrates a connecting plate part 4 which is longer than the thickness of insulation 6 plus the thickness of finishing plate 2, so that a space 28 arises between this finishing plate and turn 7, possibly supplemented with sealing 8.

[0064] Fig. 10B illustrates how this space is employed for adding a second finishing plate 29 during construction and securing it between finishing plate 2 and turn 7 of fastening part 3.

[0065] Figs. 11A-B illustrate a variation of an elaboration of the invention having two connecting plate parts and two fastening parts. Here, a building component having more or less the appearance of a sandwich panel is formed, at least when seen from the outside.

[0066] Fig. 11A illustrates the building component concerned with outer plate part 5, insulation 6 and finishing plate 2. The longitudinal edges are formed by the connecting plate parts 4 and 4¹. Insulation 6 can comprise plastic foam or mineral wool or a combination thereof and is connected to outer plate part 5 and optionally to said connecting plate parts. Finishing plate 2 is connected to insulation 6 and/or fastening parts 3 and 3¹. Said finishing plate can, when mounting insulation in the form of plastic foam, be used as part of the mould of said foam.

[0067] The transition of outer plate part/connecting plate part 4¹ contains a turn 31 covering the connection and the fastening and connecting to and fitting in a corresponding turn 30 at the transision of outer plate part 5 and connecting plate part 4 of a formerly positioned building component. The transition connecting plate part 4¹/fastening part 3¹ contains a turn 33 for clamping said component in a corresponding turn 32 at the transition of connecting plate part 4/fastening part 3 of a formerly positioned building component.

[0068] Fig. 11B illustrates the longitudinal connection between two consecutively mounted building components and the way in which turns 30 and 31, 32 and 33, respectively, connect. Between turns 30 and 31 is a space 34 offering room to fastening 16 of building component 1 into rear structure 15. Turn 31 of subsequently placed component 1¹ hides the fastening from view from the outside. During mounting, turn 33 of building component 1¹ falls into turn 32 of building component 1 already mounted, causing building component 1¹ on this position, without any fastening of its own, to be secured to rear structure 15 through building component 1. An additional sealing 35 may have been mounted at any position.

[0069] Finishing plates 2 and 2¹ form the inner finishing and thus hide the insulation from view. The connections between these finishing plates can further be finished according to one of said indicated methods.

[0070] The building component according to fig. 12 comprises an outer plate part 5, a connecting plate part 4 possibly provided with perforations, a fastening part 3, an insulating body 6 and possibly a finishing plate or foil or another finish 2.

[0071] Fastening part 3 can be provided, by means of additional turns, with a complementary cross-section 36, enhancing the moment of inertia and the cross-section of the compressive zone at the moment-fixed overlap (in case of support on the column) in cooperation with the fastenings to be mounted there. Turns producing a more sleeve-shaped fastening parts are also possible. Extension 37, as part of the stiffening ribs in outer plate part 5, extends connecting plate part 4 and thus enhances the moment of inertia of the effective cross-section of said building component.

[0072] The blank in the flat plane according to fig. 13A comprises an outer plate part 5 provided with ribs in the longitudinal direction of the building component, having insulating body 6 secured at the inside, a connecting plate part 4 being provided with perforations and a fastening part 3. This latter part is provided with an additional effective cross-section 36. Outer plate part 5 extends across a certain distance past the outer end of said component. Thus, this part 38 forms an overlap structure with the component abutting in horizontal direction. This component ends at its other outer end across a certain distance, preferably across a distance equal to the length of overlap 38, before the outer end of the building component. This allows for fastening this building component and the building component connecting in horizontal direction to be mounted later at the position of their mutual overlap, through fastening part 3, to the column without before-mentioned outer plate part being in the way.

[0073] Possible perforation 40 in the additional material cross-section 36 of connecting part 4 limits the material stacking to three where fastening parts 3 of adjacent components overlap.

[0074] Possible perforation 41 in the fastening part allows for positioning the building component and sliding this part under the fastening part of the previously positioned, connecting element at the location of the overlap without the (temporary) fastening to the column at this location being in the way. Possible perforation 42 is meant to limit, or prevent, the loss of material when cutting-off the components, so that thus both outer ends of the component mate exactly. Then, said perforation allows for adding the additional material cross-section 43 to connecting plate part 41 at the other outer end of said building component, said cross-section serving to enlarge the effective cross-section of said connecting plate part there and thus enhancing the strength and stiffness of the component.

[0075] Fig. 13B shows the cross-section of the building component at the location of cross-section AA with the outer plate part 5 in the form of overlap 38 and the possible cutout 42.

[0076] Fig. 13C shows the cross-section of the building component at the location of the cross-section BB with the outer plate part 5, connecting plate part 4 having the extension 37, fastening part 3 (here without additional material cross-section 36), insulating body 6 and a possible finising plate or foil 2.

[0077] Fig. 13D shows the cross-section of the building component at the location of cross-section CC, thus beyond the point where the outer plate part ends, with the connecting plate part 4 with extension 37, fastening part 3 (here with additional material cross-section 6) and additional material cross-section 43.

[0078] Fig. 14A shows the connection of four building components at the location of column 44, in which a through d indicate the order of mounting. Here, overlap 45 of the connecting fastening parts is at the location of said column. There, adjacent elements are mutually coupled and fastened to said column by means of fastening 46. Thereupon, outer plate parts represent the vertical overlap 47.

[0079] Fig. 14B shows the vertical cross-section of the construction at the location of the cross-section AA with the order of mounting a through d indicated therein.

[0080] Fig. 14C shows the vertical cross-section of the construction at the location of the cross-section BB with the order of mounting a through d indicated therein. Overlap 47 indicates how the outer plate parts of connecting components meet.

[0081] Fig. 14D shows the vertical cross-section of the construction at the location of cross-section CC with the order of mounting a through d and column 44 indicated therein. Overlap 45 indicates how fastening parts of connecting components meet and how the elements there have been fastened to colum 44 by means of fastening 46. Here, fastening part 3' of building component c is slid under temporarily fastened fastening part 3 of building component a prior to definitively fixing both of them with fastening 44. Fastenings 48 on approximately the angular points of connecting plate parts 4 and 4' overlapping there provide for a moment-fixed coupling of adjacent components.

[0082] Fig. 14E shows the vertical cross-section of the construction at the location of cross-section B'B' with the order of mounting a through d and column 44 indicated therein. This cross-section runs exactly along the edge of connecting plate part 4' of building component c.
