(54) Construction element and method for constructing a wall


(57) The present invention relates to a construction element (1,1b,1c) for constructing a wall of a building, comprising a support structure (2) assembled from a sheet (3) which is formed such that the support structure (2) is provided with a front surface (2a), a first side surface (2b) and a second side surface (2c) lying opposite the first side surface (2b), and a filling (4) extending substantially within the space defined by the front side (2a), the first and second side surfaces (2b,2c), wherein the first side surface (2b) comprises a coupling part formed as at least one protrusion (5) and the second side surface (2c) comprises a coupling part formed as at least one recess (7) for the purpose of coupling the construction element (1b) to a construction element (1c) of similar form.




Description


[0001] The present invention relates to a construction element. The invention also relates to a method for constructing a wall.

[0002] Known construction elements are usually constructed as sandwich panels, wherein a filling extends between two sheets situated at a mutual distance. The filling is optionally also covered on its sides. Although such panels provide a good thermal and/or sound insulation, they are relatively heavy, which makes construction more difficult. A known solution here is the omission of one of the two sheets situated at a mutual distance. Although this does make the construction element lighter, the construction element hereby also loses a considerable part of its stiffness, this adversely affecting the stiffness of the construction of the erected wall.

[0003] The invention therefore has for its object to provide a construction element for constructing a wall, roof or floor which is light, manageable and user-friendly and also has sufficient stiffness, and to provide a usable alternative to the already existing construction elements. The invention also has for its object to provide a method for constructing a wall.

[0004] The invention provides for this purpose a construction element for constructing a wall, roof or floor of a building, comprising a support structure assembled from a sheet which is formed such that the support structure is provided with a front surface, a first side surface and a second side surface lying opposite the first side surface, and a filling extending at least within the space defined by the front side, the first and second side surfaces, wherein the first side surface comprises a coupling part formed as at least one protrusion and the second side surface comprises a coupling part formed as at least one recess for the purpose of coupling the construction element to a construction element of similar form, wherein the protrusion of the first construction element is received in the recess of the second construction element. Although the forming of a construction element according to the present invention is very time-consuming because the sheet has to be deformed at multiple locations and in different folding directions, wherein in particular the sheet is folded round a plurality of fold lines, an exceptionally advantageous construction element is however provided, wherein the recess and protrusion on the sides of the support structure form parts stiffening the construction element. Construction elements can hereby be mutually coupled such that the thus erected wall has a sufficient stiffness. The construction element according to the present invention, which over the same surface area is lighter than known construction elements, makes it possible to erect a wall with sufficient stiffness in user-friendly manner. A wall is understood here to mean an optionally flat or curved or inclined partition such as a wall between spaces, and a roof or floor. The construction element according to the present invention is distinguished from known construction elements embodied as sandwich panel in that it is not embodied as two sheets situated at a mutual distance between which a filling extends, wherein the sheets form the front and rear surfaces of the construction element, but is conversely characterized in that it has a first and a second side surface, which are connected to a front surface of the construction element and thus contribute toward the torsional stiffness of the construction element. The construction element according to the invention can advantageously be applied in the erection of a wall intended as roof or part thereof. Because the construction elements can be coupled to each other with their stiff side surfaces, the construction elements can be placed directly on the inner side of an outer wall of a roof without interposing the usually applied girders. Owing to the stiffness of the side surfaces of the construction elements the usually applied girder is as it were integrated with the construction element. A similar advantage is gained when constructing a floor; here too the construction element can be placed on the existing substrate, such as a supporting concrete floor, directly and without interposing a girder. In both applications the advantage obtained is a gain in height in the associated space. Although it is not precluded that the filling is arranged in the support structure at the location where the wall is constructed, the filling is preferably arranged during manufacture of the construction element. The support structure can be filled in a more controlled manner by arranging the filling in the support structure during manufacture. Poorly accessible locations, such as in and around the recess and protrusion, can be filled with a higher degree of filling, whereby the strength and stiffness of the construction element increases. A construction element provided with a filling is also more user-friendly since the additional step of filling the support structure has already taken place prior to mounting. Because the first side surface comprises a coupling part embodied as at least one protrusion, a construction element according to the present invention can be easily screwed to a carrier such as a vertical or horizontal beam. Although a filling placed loosely in the support structure is not precluded, the filling is preferably connected to the support structure, such as by means of an adhesive connection. The adhesive connection can here be obtained in that the filling itself forms an adhesive connection with the support structure, for instance during the arranging of an optionally liquid filling. A separate adhesive layer can however also be arranged on the support structure and/or the filling prior to the filling being arranged. This reduces the risk of undesirable displacement of the filling relative to the support structure or the filling even being displaced completely outside the support structure during mounting of the construction element and/or mutual coupling of the construction elements. A stiffer and stronger construction element is hereby also obtained, since forces exerted on the construction element, particularly shear forces, are transmitted to the filling through the adhesive connection.

[0005] In a first embodiment the support structure comprises a front surface, first side surface and a second side surface lying opposite the first side surface which are formed only by the sheet. This makes the construction element relatively light, wherein the support structure still provides sufficient stiffness for the purpose of erecting a wall. The sheet is formed here such that the front surface and the two sides surfaces form part of this one sheet.

[0006] In a practical embodiment the support structure has a thickness extending transversely of the front surface and the coupling parts extend within the thickness of the support structure. A stiff construction element is hereby provided with which a wall, roof or floor can be constructed with a thickness which remains limited. The construction element is particularly designed such that the coupling parts of mutually coupled construction elements are not visible from the front side. The support structure is particularly adapted here to absorb bending forces in that the sides of the support structure extend from the front side of the support structure over at least 60%, preferably at least 75% and most preferably at least 82% of the thickness of the construction element. A simple construction element is hereby provided which combines a great strength and stiffness with a relatively low weight.

[0007] The construction elements can be mutually coupled in various ways. The coupling parts formed as protrusion and recess can thus be formed such that the protrusion is held clampingly, i.e. under bias, in the recess in a situation where adjacent construction elements are mutually coupled. The support structure preferably comprises mounting surfaces situated on the first and second side surfaces for mutually connecting construction elements, wherein the mounting surfaces extend at at least 60% of the thickness of the construction element, preferably at least 75% and most preferably at least 82% from the front side of the support structure. In a mutually coupled situation the mounting surfaces are mutually abutting here, wherein adjacent construction elements can be mutually connected using fastening means such as a screw, adhesive and the like. A wall constructed from construction elements according to the invention can in this way also be covered in simple manner, wherein the covering can be connected easily to the mounting surfaces, and thereby to the support structure, by means of a screw. Forces exerted on the mutually connected construction elements and/or the covering layer are here transmitted directly into the support structure. Because the forces are transmitted directly into the support structure and not via the filling into the support structure, a stronger and also more durable wall is hereby provided.

[0008] In a subsequent embodiment the support structure has a width over which the coupling parts extend. Not only is the manufacture of the construction element hereby simplified, since the protrusion and recess can be obtained in simple manner by folding the sheet, the mutual coupling of the construction elements is also user-friendly. The recess of a first construction element can after all be coupled at any position to the protrusion of a second construction element, after which the first construction element can be displaced to a desired position relative to the second construction element by sliding the recess relative to the protrusion.

[0009] The protrusion and the recess of the construction element can be formed and oriented in diverse ways, and they can for instance form an angle with the front surface of the support structure. In particular, the first and second side surfaces extend substantially transversely of the front surface and the protrusion and recess extend substantially parallel to the front surface of the support structure. This increases the bending stiffness in a direction transversely of the front surface. The front sides of construction elements optionally wholly coupled to each other particularly extend here in substantially the same plane.

[0010] The construction element can be dimensioned in varied manner. The height of the construction element lies particularly between 300 - 900 mm, preferably between 375 - 825 mm and most preferably between 450 - 750 mm. The thickness can also have varying values. The thickness of the construction element lies particularly between 50 - 180 mm, preferably between 70 - 160 mm and most preferably between 90 - 130 mm. These values combine a sufficient size for constructing a wall using a limited number of construction elements with a stiffness such that the thus constructed wall is sufficiently rigid.

[0011] In another embodiment the filling extends to a position outside the space enclosed by the support structure. The filling particularly extends beyond the thickness of the construction element defined by the sheet. The distance over which the filling extends beyond the thickness defined by the support structure preferably lies between 10 and 60 mm, more preferably between 20 and 40 mm, and is most preferably about 30 mm. These measures prevent the occurrence of a thermal bridge.

[0012] The protrusion and the recess can also be dimensioned in various ways. The protrusion particularly has a height lying between 10 - 50 mm, preferably between 20 and 40 mm, and the recess has a depth lying between 20 - 60 mm, preferably between 30 and 50 mm. Such protrusions and recesses impart sufficient stiffness to the constructed wall, while the construction elements can be mutually coupled in simple manner.

[0013] Although the height of the protrusion and the depth of the recess can be substantially equal, it is advantageous if the height of the protrusion is smaller than the depth of the recess. This reduces the risk of the construction elements not being fully coupled, for instance because a small object such as dirt is present in the recess.

[0014] In an advantageous embodiment the construction element comprises a sealing body situated in the recess and extending over the length of the recess for the purpose of coupling a second, construction element of similar form medium-tightly to a first construction element. A wall, roof or floor can hereby be constructed which for instance allows through no or hardly any moisture and/or air. The sealing body is particularly embodied as an elongate resilient body and preferably connected to the construction element, for instance by means of a rubber strip, an adhesive connection or a double-sided adhesive tape. It is advantageous here when the height of the protrusion is smaller than the depth of the recess such that the construction elements can be mutually coupled under bias, wherein the protrusion of a first construction element urges the resilient body into the recess of a second construction element coupled to the first construction element. A medium-tight closure is hereby obtained in simple manner, this being particularly desirable for preventing draught.

[0015] In yet another embodiment the first and second side surfaces comprise a support surface for supporting a second construction element, to be coupled to a first construction element, against the first construction element. A stable coupling between construction elements is hereby obtained, this enhancing the stiffness and the alignment of the construction of the thus constructed wall.

[0016] In another embodiment the first side and/or the second side of the support structure is provided at a distance from respectively the protrusion and/or recess with a profile for the purpose of imparting stiffness to the first and/or second side of the support structure. Owing to such a profile the sides of the construction element acquire a greater stiffness, whereby a girder function is provided. The profiles in the first side and/or the second side of the support structure can be formed respectively as a recess and/or as a protrusion. The profiles can hereby be mutually abutting in a coupled position. The profiles in the first side and/or the second side of the support structure can both also be formed as a recess. In the coupled position a space is hereby obtained which can be utilized. A fire-resistant element or cabling such as an electricity cable, network cable and so on can for instance thus be placed in the resulting space.

[0017] On the front side the sheet can be substantially flat, which may be aesthetically desirable. The sheet can also comprise grooves, which makes the support structure stiffer. The grooves can extend in random directions. The grooves particularly extend parallel to each other in a direction parallel to the side surfaces. It is possible here to embody the grooves with a profile, such as a triangular profile, which has the same dimensioning as a groove which results at the location where two adjacent construction elements are mutually abutting. This creates a symmetrical and finished appearance of a wall, roof or floor manufactured by means of construction elements according to the present invention. It is noted particularly that the construction element is intended, or is at least particularly suitable, for the purpose of finishing an inner side of an outer wall, roof or floor, wherein the sheet is directed, after assembly, toward the interior of a building of which the wall forms part, and thus forms the interior aspect of the building.

[0018] The sheet can be manufactured from diverse materials. The sheet is particularly manufactured substantially from a material selected from the group consisting of: metal, metal alloy, plastic and composite. Such materials combine a sufficient strength and stiffness with a sufficiently low weight. The metal particularly comprises steel or an alloy thereof, wherein one of the components is preferably zinc.

[0019] The filling can likewise be manufactured from diverse materials. The filling is particularly manufactured substantially from a material selected from the group consisting of: PUR foam, PIR foam, phenol foam, polystyrene, and glass wool, rockwool and a natural material such as pressed loam, wood and the like. Such materials are light and have a sound and/or thermally insulating effect. The filling is particularly manufactured substantially from a foam, such as PUR foam, PIR foam, phenol foam and/or mineral wool. PIR (polyisocyanurate) foam in particular contributes less toward a possible fire.

[0020] In an advantageous embodiment the rear side of the construction element is provided with a covering. A covering protects the construction element from weather influences such as moisture. The covering can already be arranged on the construction element prior to construction of the wall. The covering can thus already be arranged on the construction element during manufacture, which particularly simplifies the finishing of the subsequently constructed wall. The covering can however also be arranged after construction of the wall. A covering is hereby obtained which can consist of a single piece and which extends over the whole rear side of the wall. Although the covering can be embodied in diverse ways, the covering is particularly a foil, preferably an aluminium foil. The covering, also referred to as lamination, is preferably arranged during manufacture, whereby the filling remains better positioned inside the support structure since the risk of the filling displacing out of the support structure, for instance because it sticks to or catches on another object, is reduced. Such a foil is also heat-resistant.

[0021] The invention also provides a wall comprising a plurality of mutually coupled construction elements according to any of the foregoing claims. For the advantages of the wall according to the present invention reference is made to the advantages of the construction element according to the present invention as already described above.

[0022] In a first embodiment the wall is characterized in that a profile element is situated between the first side of a first construction element and a second side, adjacent to the first side, of a second construction element coupled to the first construction element, which profile element lies against at least two surfaces of a side of each support structure of the two mutually coupled construction elements. A wall constructed from the construction elements according to the present invention is strong and stiff, this being further improved by the presence of a profile element situated between two coupled construction elements. If a bending force is exerted on such a constructed wall, the profile element will at least partially absorb the bending forces and therefore at least partially prevent further bending.

[0023] The invention further provides a method for constructing a wall, comprising of: providing a plurality of construction elements according to the invention and coupling a second construction element to a first construction element by placing a recess of the second construction element in the protrusion of the first construction element. For the advantages of the method according to the present invention reference is made to the advantages already discussed above of the construction element according to the present invention.

[0024] In a first embodiment a profile element is placed against a side of a construction element prior to coupling of a second construction element to a first construction element, wherein the profile element is clamped against at least two surfaces of a side of each support structure of two mutually coupled construction elements. The thus constructed wall is hereby further strengthened.

[0025] In another embodiment the first construction element is connected to at least one carrier, prior to coupling of a second construction element to a first construction element, by connecting the male coupling part of the first construction element to the carrier using connecting means such as a screw. This imparts increased strength and stiffness to the thus constructed wall. The construction elements can for instance be connected to uprights extending in vertical direction. After connecting the construction elements to the uprights on a first side, and thus constructing a wall, a wall can likewise be constructed and fixed on an opposite side. A double-walled structure is thus obtained, with improved sound insulating and thermally insulating action.

[0026] The present invention will be further elucidated on the basis of the non-limitative exemplary embodiments shown in the following figures. Identical components are designated in the figures with the same reference numerals. Herein:

figure 1 shows a cross-section of a construction element according to the invention;

figure 2 shows a cross-section of a construction element according to the invention in which the dimensioning is shown;

figure 3 shows a cross-section of an embodiment variant of a construction element according to the invention;

figure 4 shows a cross-section of a number of coupled construction elements according to the invention;

figure 5 shows a cross-section of a wall according to the present invention, the wall being fixed against a carrier; and

figure 6 shows a cross-section of a wall constructed from construction element according to an embodiment variant of the present invention, this wall being fixed against a carrier.



[0027] Figure 1 shows a construction element according to the present invention designated as a whole with 1. The construction element comprises a support structure 2 with a front side 2a and two sides 2b,2c. The support structure is constructed from a sheet 3, the sheet being manufactured from a steel alloy containing zinc. Sheet 3 is shown partially with a broken line on front side 2a so as to indicate that construction element 1 is discontinuous. Support structure 2 is filled with a filling 4 manufactured from PUR foam, wherein an adhesion is obtained between the filling and the support structure during arranging of the filling in that the PUR foam is viscous during arranging thereof and has an adhesive force. It is emphasised here that the filling can however also be placed loosely in the support structure. A protrusion 5 formed from sheet 2 is situated on side 2b close to front side 2a of construction element 1. A recess 6 is situated on the side of protrusion 5 remote from front side 2a. A recess 7 formed from sheet 2 is situated on side 2c close to front side 2a of construction element 1. Narrow grooves 8 and wide grooves 9 are arranged on front side 2a of construction element 1. The depth of this groove 9 can be chosen subject to the intended application. A deeper groove has the advantage of providing more bending stiffness and can be applied particularly when the construction element is mounted on an inclining surface so that little or no dust will accumulate in the groove. Profiles 10 are also arranged on the sides (2b,2c). Grooves (8,9) and profile 10 serve to strengthen and increase the stiffness of construction element 1. Due to profile 10 the sides 2b,2c of the construction element do after all acquire a greater stiffness, thereby providing a girder function. Profiles 10 of construction element 1 can be directed inward in a first side and outward in a second side so that they fit into each other when two construction elements are coupled, although for the purpose of providing the option of applying an additional reinforcement, as will be elucidated with reference to figure 4, it is advantageous if they are directed inward in both sides as shown in figure 1. On its rear side opposite front side 2a the construction element also comprises a covering 11 embodied as aluminium foil.

[0028] Referring to figure 2, construction element 1 of figure 1 is shown, wherein dimension references are indicated. The dimensioning of the construction element as shown here has the following indicative dimensioning (wherein the designation of the length in parenthesis where applicable):
  1. a: 40 mm
  2. b: 5 - 45 mm
  3. c: 37 mm (depth of the recess)
  4. d: -
  5. e: 40 mm
  6. f: 20 - 60 mm
  7. g: 60 mm
  8. h: 45 mm
  9. i: 45 mm
  10. j: 20 mm
  11. k: 18 mm
  12. l: 17 mm (the width of the recess)
  13. m: 15 mm (the width of the protrusion)
  14. n: 70 - 160 mm (thickness of the construction element)
  15. o: 30 mm (the height of the protrusion)
  16. p: 450 - 750 mm (height of the construction element)
  17. q: 30 mm (distance of the protruding part of the filling)


[0029] The length of the construction element can further vary greatly and can lie between 1 metre and 12 metres, and even longer if desired.

[0030] Figure 3 shows an embodiment variant of the construction element of figure 1. On the side opposite front side 2a of support structure 2 the filling 4 here extends to a position outside the space enclosed by support structure 2. The distance q over which filling 4 extends out of the space enclosed by support structure 2 relative to the parts 26 extending parallel to a rear surface is in this embodiment 30 mm. Filling 4 extends over the height p of the construction element such that a part 26 situated on a side 2c of a first construction element 1 abuts a part 26 lying on a side 2b of a second construction element 1 of similar form coupled to the first one. Construction element 1 also comprises a sealing body 28 located against a side edge 4a of filling 4. Sealing body 28 ensures that a wall constructed from mutually coupled construction elements 1 is sealed from a medium such as moisture or air.

[0031] Referring to figure 4, mutually coupled construction elements 1a,1b,1c of similar form are shown. Side 2b of construction element 1a is here adjacent to side 2c of construction element 1b. Protrusion 5 on side 2b of construction element 1b extends here into recess 7 situated on side 2c of construction element 1a. Side 2b of construction element 1b is here likewise adjacent to side 2c of construction element 1b. Protrusion 5 on side 2b of construction element 1c extends here into recess 7 situated on side 2c of construction element 1a. In this way a complete wall can be constructed (see also figure 4). Front sides 2a of sheet 2 of the construction elements (1a,1b,1c) extend here in one plane. Figure 5 shows a wall 20 constructed from construction elements (1a,1b,1c). Construction elements (1a,1b,1c) are mutually coupled as described in figure 4, wherein elongate sealing bodies 23 are placed in recesses 7. The sealing bodies have a circular section and are manufactured from rubber. After placing of a construction element (1b) on a construction element (1c) of similar form situated thereunder, sealing body 23 will be clamped between the two coupled construction elements (1b,1c) partly due to the own weight of the construction element (1b). The coupling between the construction elements (1b,1c) is hereby sealed for passage of air and/or moisture. Profile elements 24 are also situated between the mutually coupled construction elements (1a,1b,1c), which profile elements 24, being in the shown embodiment Z-profiles advantageously available as standard product, extend into recess 7 of a construction element (1a,1b), lie against sides 2b of construction elements (1b,1c) and extend to the rear side 2d of a construction element (1b,1c). Such profile elements 24 improve the connection of the mutually coupled construction elements (1a,1b,1c). Construction elements (1a,1b,1c) are also fixed against a carrier 21 embodied as an upright extending in vertical direction. For this purpose screws 22 extend through protrusions 5 of construction elements (1a,1b,1c) into carrier 21. Screws 22 are placed on the protrusions such that they extend through recesses 6.

[0032] Construction of wall 20 proceeds as follows. A lowermost construction element 1c is placed against carrier 21. A screw 22 is placed in recess 6 of protrusion 5 and screwed into carrier 22. A profile element 24 is placed against the fixed construction element 1c. A subsequent construction element 1b is placed on the fixed construction element 1c, wherein recess 7 of construction element 1b is placed round protrusion 5 of the fixed construction element 1c and profile element 24. The sealing body is here also clamped between construction elements 1b,1c. This is possible because the depth of recess 7 (c) is smaller than the height of protrusion 5 (o) and the diameter of sealing body 23 together (see also the description of figure 2). This construction element 1b coupled to construction element 1c is then fixed to carrier 21 in the same way. Once a wall 20 with a desired height has in this way been obtained, an additional covering 25 is arranged if desired on rear side 2d so as to further prevent air and/or moisture penetrating between and thereby into and/or through the construction element. Covering 25 can be a foil. The covering can also be a band or strip for covering joins between adjacent construction elements of a wall. The strip or band is placed particularly over the vertically extending joins, since the filling over these edges of adjacent construction elements is left clear and the danger of moisture in particular acting on the filling can in this way be prevented. The band or strip particularly comprises an adhesive layer for simple arranging of the band or strip on the wall. Covering 25 can also be a rigid covering - such as a plating - which is for instance fixed by means of screws to part 26 of support structure 2 extending parallel to a rear surface.

[0033] Referring to figure 6, another wall 20 is shown which is constructed from construction elements 1b,1c, which are an embodiment variant of the construction element of figure 3. Construction of wall 20 takes place in similar manner as described with reference to figure 5. In construction element 1 according to this figure 6 the support structure 2 comprises on side 2b a mounting surface 29a remote from front side 2a of construction element 1 and on side 2c a mounting surface 29b directed toward front side 2a of construction element 1 for the purpose of mutual assembly of adjacent construction elements 1. Mounting surfaces 29a,29b are formed integrally from sheet 3 and extend from front side 2a of support structure 2 over 75% of the thickness n of construction element 1. A screw 30 is placed in construction element 1 from the rear side of construction element 1 for mutually coupling adjacent construction elements 1. Screw 30 extends here through the part of filling 4 extending outside the space enclosed by support structure 2 of construction element 1b, through mounting surfaces 29a,29b of adjacent construction elements 1 and through filling 4 of construction element 1c. A strong connection of adjacent construction elements 1 is hereby obtained. Such a method of mutually connecting construction elements 1 also imparts an increased stiffness to wall 20.
