A modular structure

Description

[0001] The present invention relates to a modular structure, as described in US-A-4 020 611 and US-A-3 299 270. It is known in building construction to form vertical walls, for example of a load-bearing type, by casting pillars of reinforced concrete and filling the space between adjacent pillars with a curtain wall comprising prefabricated sheet-like elements or elementary modules (normally made from brick and/or concrete) connected together. These vertical walls are then finished with a layer of thermally insulating material which is normally placed in a cavity within the curtain wall or is applied to an outer face.

[0002] The creation of this cavity and, in any case, the arrangement of the thermally insulating layer, takes a long time to carry out (and this involves additional costs) and must be effected by a specialised workforce. It is also known to form horizontal platforms, such as slabs, by providing a plurality of perforated brick elements and laying them side by side on a temporary horizontal structure and casting a layer of cement mortar over these brick elements to form a flat horizontal surface which is then finished with a layer of thermally insulating material applied to one face of the horizontal platform. In a similar manner to the above, the application of the layer of thermally insulating material involves additional construction time (and hence costs) and must be carried out by a specialised workforce.

[0003] US-A-3 802 134 describes a modular structure according to the preamble of claim 1 and a combination according to the preamble of claim 14.

[0004] The object of the present invention is to provide a structural element which can be used in combination with other structural elements to form a modular structure usable as a vertical wall or a horizontal platform, in which the arrangement of the thermally insulating layer is carried out in a single operation with the creation of the modular structure itself.

[0005] Accordingly the present invention provides a modular structure of the type described in Claim 1. According to the present invention there is also provided a combination of structural element for a modular structure and connector means of the type described in the Claim 14.

• Figure 8 illustrates an element of the framework of Figure 6.

[0007] In Figure 1 a structural element usable in building construction work for the formation of modular structures is generally indicated 1. The element 1 includes a central portion 3 comprising a flat rectagular sheet and two side connector portions 5, 6 formed as straight side walls integral with the sheet 3 and projecting from the longer sides thereof. More particularly, the structural element 1 has a channel section with the walls 5, 6 extending substantialy perpendicularly from a flat rear face 8 of the sheet 3; the walls 5, 6 have substantially the same height h and a cross-section which tapers towards a free edge (for example the walls 5, 6 may have a trapezoidal cross-section). The central portion 3 and the side connector portions 5, 6 are made from reinforced concrete. The side walls 5, 6 have respective opposite end portions 5a, 5b and 6a, 6b from which project metal elements 7 forming part of the inner reinforcement (not shown) of the reinforced cement portions. More particularly one metal element 7 may be in the form of a hook usable for engagement and lifting of the structural element 1.

[0008] The structural element 1 further includes a layer of thermally (and acoustically) insulating material 10, conveniently made from a rectangular sheet of expanded polystyrene (or other thermally insulating material), coupled to the central portion 3 in contact with the rear face 8. More particularly, the sheet 10 is rectangular with longer edges 10a, 10b located in contact with base portions of the straight side walls 5, 6. Thus the sheet 10 extends between the walls 5 and 6 over the entire width L of the rear face 8.

[0009] The structural element 1 further includes an outer facing layer 12 applied to a front face 14 of the rectangular sheet 3 and having a substantially constant thickness. The outer facing layer may, for example, comprise lightweight concrete, cellular concrete, hydraulic lime mixed with polystyrene, a fire-retardant material in general or an outer cladding of brick or stone.

[0010] The structural element 1 is adapted to cooperate with a connector element device 18 (Figure 2) which, in the embodiment illustrated in Figure 2, comprises a parallelepipedal block of thermally insulating material (for example expanded polystyrene) of a length at least equal to the length of the structural element 1. The connector element device 18 has two straight trapezoidal-section channels 21, 22 which extend parallel to each other in a flat face 23 of the parallelpipedal block 18.

[0011] In use, the structural element 1 may, to advantage, be used to form a horizontal platform, for example a load-bearing slab, as illustrated in Figure 2. For this purpose several structural elements are located side by side with the walls 5, 6 parallel and facing each other. The rectangular sheets 3 are also located so as to be coplanar, for example by the placing of the structural elements on a flat supporting surface 24 (illustrated schematically) of a load-bearing structure (not illustrated). The end portions (not illustrated) of the structural elements 1 may also be rested on respective vertical load-bearing walls (not shown) which support the structural elements themselves. The blocks 18 are also located so as to interconnect the adjacent structural elements, the channels 21, 22 of a block 18 housing respective walls 6 and 5 of adjacent structural elements. In this arrangement, the face 23 of each block 18 is in cooperating contact with the insulating layers 10 of the adjacent structural elements so as to form therewith a substantially continuous covering layer 25 of the modular structure comprising the adjacent structural elements 1 interconnected by the connector elements 18. The adjacent parallelepipedal blocks 18 also define, with the layer 10, straight, rectangular-section channels 28 in which steel reinforcements 30 may be arranged and in which a cement layer 33 may subsequently be cast so as to form load-bearing beams when the cement has hardened.

[0012] The advantages of the modular structure described above are as follows:

• the adjacent structural elements are interconnected and a continuous thermally-insulating layer is created, extending over the entire horizontal platform, in a single operation;
• the structural elements 1 are interconnected by simple operations, without the aid of special equipment and without the need for a specialised workforce - the modular structure can thus be assembled simply and quickly; and
• modular structures may be formed of any dimensions from different numbers of structure elements.

[0013] With reference to Figure 3, the structural elements 1 may be used with connector elements 18a each comprising an elongate, substantially parallelepipedal body with a pair of parallel channels 21a, 22a in a first face 36 and a pair of parallel channels 40, 41 in a second face 46 of the body 18a opposite the face 36. The body 18a, as described for the connector element 18, has a length at least equal to the length of the structural element 1 to which it is applied.

[0014] The structural elements 1 of Figure 3 are used to form a vertical load-bearing wall. For this purpose, a first plurality of structural elements 1a is arranged alongside each other with the walls 5, 6 parallel and adjacent. The rectangular sheets 3 are then disposed vertically and in the same plane, for example with the use of an external supporting framework (described below). The blocks 18a are arranged so as to interconnect the adjacent structural elements, with the channels 21a, 22a of a block 18a housing respective walls 6 and 5 of adjacent structural elements. In this arrangement, the face 36 of each block 18a is in cooperating contact with the insulating layers 10 of the adjacent structural elements to form therewith a substantially continuous first covering layer 25a. A second plurality of structural elements 1b is arranged side by side and facing the structural elements of the first plurality, with the rectangular sheets 3 vertical and parallel to the corresponding sheets of the structural elements 1a. The blocks 18a are disposed so as to interconnect adjacent structural elements 1b, the channels 40, 41 of a block 18a housing respective walls 6 and 5 of the adjacent structural elements 1b. In this arrangement, the connector elements 18a are interposed between the connector wall portions 5, 6 of the structural elements 1a and the connector portions 5, 6 of the structural elements 1b. The connector elements 18a thus fulfil the dual function of interconnecting the adjacent structural elements 1a and 1b and separating and spacing apart the facing structural elements 1a, 1b.

[0015] In this arrangement, moreover, the face 46 of each block 18a is in cooperating contact with the insulating layers 10 of the structural elements 1b to form therewith a second substantially continuous covering layer 50 parallel to and facing the covering layer 25a.

[0016] A structural element 1a and a structural element 1b facing each other together define, with the pair of connector elements 18a which separate them, a substantially parallelepipedal cavity 55 bounded by the facing layers of insulating material 10 and the side faces of the connector elements 18a. A steel reinforcement (not shown) may be arranged in the cavity 55 and subsequently a layer of cement mortar ( not illustrated) may be cast around it so as to form, when the cement has hardened, load-bearing pillars which are firmly connected to the structural elements 1a and 1b. Pipes, connecting cables etc. may also be housed in the cavity 55.

[0017] The advantages of the modular structure described above are as follows:

• the structural elements may be interconnected and the two continuous thermally-insulating covering layers, extending over the whole vertical wall, may be created by the simple operations described above;
• the modular structure with the double-layer of insulating material described above prevents the ingress of cold into the building comprising the structure itself and simultaneously prevents heat from dispersing from the building;
• the modular structure also has good sound-proofing properties;
• the presence of two facing thermally-insulating layers encapsulating an intermediate cement portion forms a modular structure having a high thermal inertia: this prevents a sharp 'meeting', within the modular structure, between the temperature outside the building and that inside the building itself (which is higher than the outside temperature). This prevents condensation forming on the surface of the modular structure facing into the building itself;
• formwork is not required for the casting of the cement since the cavity 55 described above itself constitutes the formwork;
• both vertical load-bearing walls (when all the cavities 55 in the structure are filled with reinforced concrete) and partition walls may be formed;
• the structural elements 1a, 1b are coupled together by simple operations, without the aid of specialised equipment and without the need for a specialised workforce - the modular structure can thus be assembled quickly and simply; and
• vertical walls of any width can be made by the assemblage of any number of structural elements.

[0018] Figure 4 illustrates a plurality of first and second vertical structural elements arranged facing each other to form a vertical load-bearing wall similar to that illustrated in and described with respect to Figure 3. Rectangular apertures 60 are left open in this vertical load-bearing wall and are bounded by facing side wall portions 61, 62 of the vertical wall; each is defined by lateral portions 5, 6 of the facing structural elements and by the connector element 18 interposed between them. The aperture 60 may be closed by a rectangular panel 65 having a rectangular aperture 66 defining a doorway in the vertical wall. The lower part of the aperture 66 may be closed by a rectangular panel 67 to form a window opening in the vertical load-bearing wall. The side wall portions 60, 61 may also be faced with rectangular sheets 68, 69 having a height substantially equal to the height of the aperture 66 and adapted to support an upper L-shaped cross-beam for resting on peripheral portions of the shorter sides of the sheets 68, 69.

[0019] Figure 5 illustrates the upper portion of a vertical load-bearing wall similar to that illustrated in, and described with reference to, Figure 3. This vertical wall supports a plurality of structural elements 1 arranged horizontally and having straight end portions located so as to face upper straight portions of the vertical wall. In this position, the metal elements 7 which project from the horizontal structural elements close to the vertical wall extend into an upper region T of the vertical wall into which the metal elements 7 of the vertical wall itself also extend. Cement mortar may be poured into this region T so as to form a reinforced concrete beam which extends across the top of the vertical wall and connects the latter to the horizontal structural elements. Similarly, the horizontal structural elements disposed next to each other and in alignment have adjacent end portions from which metal elements 7 project so as to face each other across a region R. The region R extends along the adjacent portions of the structural elements 1 and is adapted to house a metal reinforcement over which cement may be poured to form a section-break, horizontal, load-bearing cross-member extending transverse the structural elements 1 and interconnecting their adjacent end portions. The cross-members do not interrupt the thermally insulating layer defined by the horizontal structural elements.

[0020] Figure 6 illustrates a framework 80 used for supporting the vertical structural elements to form a vertical load-bearing wall as described above with reference to Figure 3. The framework 3 comprises a plurality of straight connector devices 81 coupled together so as to form straight retaining structures which extend on opposite sides of the vertical wall. Each connector device comprises a rectangular plate 83 from which extend two parallel, straight tie-bars 84, 85. Each connector device 81 further includes a straight appendage 87 which projects from the opposite side of the plate 83 from the straight tie-bars 84, 85. The straight appendage 87 (Figure 7) has a hook-shaped end portion 87a which is adapted to fit into a slot 90a in a first end of a straight plate 90 extending through the connector element 18 and having a second end portion with a slot 90b coupled to the straight appendage 87 of a connector device 81 located on the opposite side of the vertical wall. Thus the plate 90 interconnects the straight appendages of two connector device 81 on opposite sides of the vertical wall, ensuring the relative positioning of the structural elements 1a and 1b facing each other. The plate 90 is withdrawn from the connector element 18 after casting in order to eliminate the thermal bridge which the plate 90 itself would form if retained within the vertical wall. Following the withdrawal of the plate 90, the insulating material constituting the element 18 expands into the slit in which the plate 90 was housed, closing this slit.

[0021] The free end portions 84a, 85a (Figure 6) of the tie-bars 84, 85 are also connected to a plate 83 of a contiguous connector device so as to be slidable axially but fixed against rotation and, hence, without the possibility of separation from the vertical wall.

[0022] Finally it is clear that modifications and variations may be made to the modular structure described without thereby departing from the protective scope of the present invention as described by the appended claims.
