α93·»33 nnpn1? ηιτπ' nanyo Set of elements for the construction of buildings The invention relates to a building structure framework of the type composed of prefabricated elements.

Building structure frameworks of the aforesaid type are described, e.g. in the specification of French Patents 1,494,988 and 1,517,917 and British Patent No. 1,127,371.

The building structure framework of the invention comprises a plurality of base plates including anchoring projections depending from the bottom surface thereof and tubular protuberances extending vertically from the upper surface thereof, said base plates embedded in concrete footings with the protuberances projecting through and above said footings, hollow posts fitted over said protuberances, beam supporting members, hollow studs depending from said supporting members and connected to the tops of said posts, said beam supporting members having a plurality of vertically disposed hopper-like openings, hollow beams mounted on said supporting members and adapted to support reinforcing elements, said beams having a longitudinally extending slot in their upper wall, a reinforcing bar member fitted in each of said posts and extending into said hollow studs of said beam supporting members to connect said protuberances to said hollow studs, and upon pouring concrete through said slot in the upper surface of said beams, said concrete fills the hollow posts, the hollow studs and the vortically disposed openings in said beam supporting members and said beams providing an integrated structural framework* 43342/2 An embodiment of the invention and variations of this embodiment will now be described with reference to the accompanying drawings, in which: Fig. 1 is an overall exploded perspective view showing a set of elements of the building structure framework? Fig. 2 is an enlarged scale end view of the post shown in Fig. 1; Fig. 3 is an enlarged scale end view of the beam shown. in Fig. 1; Fig. 4 is an enlarged scale top plan view of the beam-supporting element shown in Figl 1; Fig. 5 is a cross-section taken along line V - V of Fig. 4; Fig. 6 is a plan view of part of a reinforcing or bracing element; Fig. 7 is a cross-section taken along line VII - VII of Fig. 6; Fig. 8 is a view similar to Fig. 6 of part of a varied form of reinforcing or bracing element; Fig. 9 is a cross-section taken along line XX - XX of Fig. 8; and Fig. 10 is a schematic cross-section through another varied form of a reinforcing or bracing element.

Fig. 1 shows a set of elements comprising a base plate 35 having anchoring projections 36 on its lower face and protuberances 6 on its upper face. Each protuberance 6 is adapted to support a tubular post 7 carrying at its upper end a member 23 for supporting beams 24, only one of which is shown partially in the drawing. 43342/2 The hollow post 7 is of generally square transverse cross-section, as can be seen from the end elevation- al view of Pig. 2, and can be made by extruding a synthetic resin. It has inner longitudinal tibs 62 whose inner edges define a cylindrical housing 63 for receiving a cylindrical, preferably tubular protuberance 6 to hold the post 7 upright The hollow post 7 also preferably has, as shown, external protuberances in the form of flanges 65 protruding in extension of its four faces, from its longitudinal edges. These flanges 65 are intended to serve as a frame former for the uprights of windows or panels disposed between adjacent posts.

The hollow post 7 serves as a non-recuperable co fer-work for a mass of concrete that can be poured therein after having introduced an armature or reinforcement such as an iron core 66 extending along its length. This iron core 66, for example, enables the base protuberance 6 to be connected to the stud 0 of a member 23 received in the upper end of post 7 (see Fig. 1 ) .

This particular form of the support member 23 is shown in detail in Figs. 4 and 5. It can, for exemple, be provided in cast aluminium and includes two supporting wings or surfaces 70 on either side of a hopper 71 placed over the hollow cylindrical stud 40 adapted to fit into the upper end of the cylindrical housing 63 of post 7. 43342/2 made rigid by ribs 72 and have a longitudinal median slot 73 for passage of an anti-seismic cable 7 (Fig. 5 ).

The hollow beams 24 whose ends are adapted to rest on the supporting wings 70 of two adjacent support members 23 may, as the posts 7, be provided* by extruding a synthetic resin. The casing of beams 24, which is of rectangular transverse section, as can .be seen in the end elevational view of Fig. 3, has a longitudinal slot 75 in its upper face and longitudinal inner ribs 76 in parallel spaced apart relation to the remaining edges of the upper face so as to define therebetween a central passage whose width is substantially the same as that of slot 7 . A transverse web 77 parallel to the upper face of the beam 24 serves to rest the two ends of the beam 24 on supporting wings 70 of two adjacent support members 2 , as shown in Fig. 3. For this purpose, the lower face or wall 78 of beam 24 is cut away at each end over a length corresponding to a third or half of the length of the upper face of the support members 23, i.e. to about the length of wings 70 .

It is thus possible to erect the framework of a building in the following manner: On a low wall defining a sanitary space or air-gap, a concrete slab is poured. A base plate 35 carrying tubular upper protuberance 6 is fixed in this slab'by embedding it under its surface. On each of the protuberances 6 is mounted a hollow post 7 with a core iron 66 disposed 43342/2 upper end of each post 7 by fitting its hollow stud 40 into the correspondin cylindrical housing 63 .

Sections of anti-seismic cable 7 are then introduced into the hollow beams 24 which are then disposed on the support members 23 on posts 7. The various sections of cable 74 are then connected together in the region of hoppers 71 of the support members 23 and the assembly of elements is tensioned.

The hollow posts 7 are then filled with concrete by the slots 75 of beams 24 and hoppers 71 of the support members 2 . The beams 24 are filled with concrete through their respective slot 75 after having disposed iron cores 80 at different levels therealong.

Numerous variations of the described embodiment may be envisaged.

The support members 23 can, for example, be provided in reinforced or non-reinforced moulded synthetic resin.

Instead of having only two supporting wings 70, certain support members 23 could for example have four or more. In every case, it is necessary to provide a common Joining piece for the various sections of anti-seismic cable in the beams, which meet in the hopper 71 of such a multidirectional support member 23 . In angle or skirting support members 2 , it is also necessary to provide members for tensioning the anti-seismic cables.

Instead of bein parallel to the upper face of 43342/2 the lateral walls of beam 2 to improve filling of the spaces defined therebetween with concrete. Similarly, the internal ribs 62 of posts 7 could be inclined to their walls.

Of course, instead of being extruded in a synthetic resin, the hollow posts 7 and beams* 24 could be made by folding and welding or sticking sheets of synthetic resin about an inner lining including the said inner ribs 62 and 76 respectively.

Instead of being filled with concrete, the hollow posts 7 and beams 24 could contain any other suitable binder including expanded plastics materials.

When a great rigidity of the framework is required, the lower metal protuberances 6 can be replaced by tubes of steel of an increased length on which the studs 40 of member 25 are directly supported.

The slab in which the base plates 35 are embedded, as well as the covering elements carried by the framework of the building, are preferably reinforced, as are the partitions, facade panels and other visible structures of the building.

A particularly advantageous reinforcing or bracing element is shown in Figs. 6 and 7. This element is in the form of a sheet having an array of trihedral protuberances 8l alternating with trihedral recesses 82 on "its two faces. It is obtained by hot embossment of a sheet of steel, aluminium, or synthetic resin, or even pressing a 43342/2 two pressure cylinders .

For this purpose, the plates of the press are provided with matrices having facing complementary trihedral protuberances and recesses. Similarly, cooperating press cylinders used for this purpose would have at their periphery complementary trihedral protuberances and hollows between which a sheet of metal or synthetic resin, or layer of paper paste, is continuously passed.

The embossments or corrugations thus obtained provide, after cooling or drying of the reinforcing elements obtained, a high multi-directional resistance to flexion and compression in particular, and enable a chosen construction material, in a pasty state, to be applied on either side thereof. This material can be concrete, notably so called cellular concrete (d<^l), or a lime mortar, or a binder with a base of a hardenable expanded or other synthetic resin, or even a fibro-cement possibly mixed with inert fillers.

Preferably, the embossing matrices or cylinders mentioned above have facing trihedral protuberances and recesses of such a shape that the apices 83 of the trihedral protuberances embossed in the sheet are truncated (see Figs. 8 and 9 ). This particular shape of the matrices or cylinders facilitates removal of the embossed. sheets from the press. Moreover, such embossed reinforcing elements in which the bottoms 84 of the recesses are pierced enable a better adhesion on either side thereof of the hardenable 43342/2 In the embodiment of the reinforcing element shown in Figs . 8 and 9 , the edges 85 of the truncated points 83 of the trihedral protuberances 8l lie in two parallel planes.

In the variation shown schematically in Fig.10 , the lower trihedral protuberances are truncated at different levels so that their truncated edges 85 define a concave curved network 86. The upper trihedral protuberances are, to the contrary, all truncated at the same level, and their truncated edges 85 define a planar network 87.

A semi-curved reinforcing element of this type can be provided by embossing a sheet of metal or a synthetic resin in a press having a plane matrix facing a convex curved matri .

Numerous other variations of the described reinforcing elements can be envisaged. The protuberances 8l and recesses 82 could, for example, be tetrahedral or hexa-hedral .

The advantages of the above-described reinforcing elements, and in particular that shown in Fig.10, reside in the appreciable economy of material that can be achieved compared to usual types of reinforcing elements, and in the facility they offer for mass production. When they are provided in synthetic resin, their cost price Is very much reduced compared to that of corresponding metal reinforcing elements. 43342/2 merits of Figs. 6 and 8 can in particular be manufactured in standard dimensions and can be superimposed by nesting protuberances 8l of the lower face of one element in recesses 8 of the upper face of another element, with a view to storage and subsequent transport. Assembly thereof at a work-site can be provided b nesting the protuberances 8l and recesses of the adjacent; edges of two reinforcing elements which are placed side by side, in extension of one another in the same plane.

It can also be noted that the reinforcing element according to Fig. 19 can advantageously be used as a planar or curved surface for the manufacture of panels or sheets for example. In effect, films, sheets or blades of any kind may easily be stuck, on either side of the reinforcing element, onto the edges 85 of the truncated trihedral protuberances. 43342/2
