DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1 and 2, the outer solid wall panel 1 is formed in large part and in a known manner from an outer wall 2 reinforced with a metal grid 3, a thick insulating layer 4, for example polystyrene, and an inner wall 11, also reinforced with a metal grid 3 . ·. According to the invention, each vertical end of the wall panel is formed at the outer wall 2 by a strip 5a on one side of the wall panel and by a strip 5b on one side of the top panel, extending over both middle portions of the wall panel. The widths of these strips correspond to the widths of the joints that will be formed horizontally and vertically to connect two successive elements together. The strip 5a may be planar for a direct joint or kinked for a corner joint of the outer walls. Each vertical end of the insulating layer 6 is formed of a thin insulating layer 6, typically of the same material as the layer.

6. Further, the vertical joint is provided with a reinforcing element 7 embedded in concrete such that the hinge eyes 8 and the anchor eyes 10 extend beyond the sides of the concrete slab. The meshes will be described below. Finally, each vertical wall panel joint has an inner wall extending the inner wall 11 of the central portion.

Further, the reinforcing elements, called ribs 12, are referred to below as ribs 12 according to the length of the prefabricated component in the component at regular intervals and parallel to the end elements. These ribs are embedded in the concrete as reinforcing elements 7 and the insulation has a smaller thickness at this point. The ribs 12 are also provided with lifting and lifting eyes, which will be described below.

The wall element is produced in the following manner in an oiled metal form. Grid reinforcement 2 is placed on the bottom of the mold on the spacers 2 · End reinforcements 7 are also placed, as well as ribs 12 if necessary, and attached to the grating frame 2 · Pour concrete into the mold, level and vibrate with vibrating rulers to form the inner wall 11. Styrofoam is placed and immersed in a vibrating ruler for polystyrene. ribs

- 5 are carefully filled with vibrated concrete, leveled to the top level of polystyrene. Next, the lattice reinforcement of the outer wall is fastened to the reinforcing elements and ribs. Then pour out the outer wall with concrete, which is vibrated and leveled with a vibrating ruler. The outer wall is then subjected to a suitable surface treatment.

In the case of outer walls with openings, metal frames 13 are attached to the bottom of the metal molds and the arrangement of the panels is such that the openings are always located between the ribs and the reinforcing elements. The opening of the opening always forms an integral part. prefabricated part.

The fastening of the frame 13 on the table is made possible by four mandrels 15 mounted in the corners of the frame. The gradual demolding of this frame is allowed by the set of working rolls. The casting of such a component is identical to that of a solid wall component.

The dividing walls (see FIGS. 5 and 6) are designed and manufactured as solid outer walls or outer walls with openings, in particular having two reinforcing elements 17 with protruding double hinge eyes 16 and possibly intermediate ribs 12 at both vertical ends of the panel, parallel to the end ribs. These parts are also provided with lifting eyes. .

parts and are. obtained by casting consisting of a horizontal top wall layer, mutually, ceiling reinforcing elements The reinforcing elements and ribs are the spans of the panel.

The ceilings are also prefabricated into molds as wall panels. They are . The wall layer and the horizontal lower interconnected ribs 12 or at the end 18, as shown in FIG. 7 and 8 arranged parallel to one another in a direction

The ceiling panels also contain insulation and lifting eyes for handling and storage. The anchor eyes 19 provided on the reinforcing elements 18 are positioned such that the distance between the first end 20 of the reinforcing element and the first eye is greater than the distance between the second end 21 and the last eye. This arrangement is chosen so that the meshes of two consecutive ceiling panels are interchanged (see Fig. 8).

The reinforcing elements and ribs will now be described more precisely. The ribs of the walls (FIGS. 10 and 12) are formed by two vertical steel bars 22, 23 held together by parallel horizontal frames 24 welded on these bars. In the upper part, one rod is extended vertically and the other is bent to form the hinge eye 8, which is used in connection with the upper panel, as can be seen from the following.

The stiffening elements 2 consist of four steel bars 26 to 31 forming a kind of beam and held together by horizontal rectangular frames 25, as shown in FIG. 9 to 11, 1 and 2. In the upper part of the reinforcing elements 7, the two outer bars 26, 27 are extended in the vertical direction and the two inner bars 30, 31 are bent into the hinge eyes 8 and the intermediate bars 28, 29 end at the level of the last frame. In addition, as shown in FIG. 1 and 2, anchoring eyes in the form of stirrups 26, at least three and at regular intervals, are provided on the side and on one side of the reinforcing element.

On some reinforcing elements or ribs, lifting eyes 9 are disposed for handling and storage by means of lifting means. These lifting eyes 9 are welded into the lifting eyes 8, as can be seen in FIG. 11, 12, 15 and 16. The ribs of the partition walls shown in FIG. 14 and 16 differ from the ribs of the other walls by the shape of their lifting eyes 8 and the lifting eyes 9.

The partition wall reinforcement elements 17 shown in FIG. 13, 15 and 6 are formed by four vertical beams 31-34 forming beams held together by horizontal rectangular metal frames welded and analogous to the frames 25 of the reinforcing elements 7 of the outer wall panels. The hinge eyes 8 in the upper part of the stiffening elements are formed by the continuity and bending of two of the bars 3 2 to 35. Alternatively, one or two lifting eyes 9 are welded there.

As shown in FIG. 6, at least three anchoring lug pairs 16, at least three, are welded to the flows 31-34, having the particularity of being horseshoe-shaped in two vertical parallel planar surfaces 36, 37 facing each other and extending on one side of the stiffening member to form a member joint an inner partition wall with a peripheral wall, or with other inner partition wall members as explained below.

The ribs of the ceiling panels shown in FIG. 7, 18 and 20 are similar to the other ribs, but are provided with eyelets 8 at both ends. These meshes are formed by bending and then welding 38 one rod to another. The reinforcing elements 18 of the ceiling panels shown in FIG. 17, 19 and 7 are formed of four beams 39-42, hinges 8 formed at the ends of the ribs of the ceiling panels and anchoring eyes 19 parallel to the rectangular frames, the meshes and frames being welded to the rods 39-42.

The method of assembling and joining the parts to each other by means of the examples of FIG. 21 to 26. FIG. Figures 21 to 26 show the principle of vertical mounting of two vertical elements. The anchoring lugs 10 of two successive panels are offset relative to one another (FIG. 23). The anchoring of the two parts takes place by means of vertical bars, such as rods 43 extending from the base and tie rods 44, which pass through a series of anchoring loops 10 belonging alternately to one and the other part. Preferably, two rows of binding rods 44 are used per vertical binding (Fig. 22).

It will be appreciated that the outer wall anchoring eyes 10a, 10b are formed by a welded bent steel bar surrounding the four bars of the stiffening element 7 supporting them, the inner bars 30, 31 and the intermediate bars 28, 29. The said bars 10a, 10b. they have either a trapezoidal yoke shape for a straight joint 45 in a row or a rectangular shape for a corner joint 46 .. In the case of a joint in a row with a partition wall (Fig. 26), ie At the T-joint, the stirrups of the two eyelets 10a of one level, but belonging to two different members, enter the planar surfaces 36, 37 of the double eyelets 16 of the horseshoe-shaped partition wall reinforcement element 17. The insertion of the bars 44 ensures the interconnection of all meshes with one another. In the case of a vertical bond joining the four inner dividing walls, four pairs of meshes of one level are joined by a metal cross piece 47 joined by welding. The corners are then removed on site and the joint is poured with concrete.

The ceiling panels, on the other hand, are laid by crane directly on the inner wall 11 of the vertical panels (see Fig. 25). The individual protruding hinge eyes of the vertical panels waiting for the ceiling panels are connected and secured by four steel bars 48. The prepared bars 22, 26 and 27 of the ribs and reinforcing elements are cast into the beads 56 of the outer wall of the wall panel. This flange 56 forms horizontal joints with the edge of the formwork ceiling panel. The upper edge of the skirt 56 is flush with the bottom of the floor. In the case of a truss connection, the vertical bars 49, left free in the vertical joints, allow the anchors 50 to be anchored to the support members.

Thus, the anchoring or interlocking of the parts between themselves can generally be ensured in various ways. On the one hand, it is secured by rods, usually two or four, inserted into the meshes perpendicular to the plane of the meshes. Furthermore, it can be provided by crossing the stirrups and the double eyes perpendicular to the stirrups, which is secured by bars perpendicular to the plane of the stirrups. Finally, the interconnection can be ensured by the placement of the cross elements on the double eyes, for example the cross elements.

The assembly of vertical and horizontal elements is finally generally sealed with conventional gaskets of elastomeric materials in accordance with applicable standards.

The prefabricated parts described above do not limit the invention. All are characterized by the ability to comprise two parallel reinforcing elements, one at each end and possibly several intermediate ribs, the reinforcing elements and ribs being attached to the grid reinforcement inserted into the workpiece.

Each reinforcement element functions as a horizontal coupling engagement element by means of one or two meshes at one or both ends. It further provides an anchoring function for a vertical bond between the panels by means of a group of meshes spaced along the length of the side of the panel and protruding therefrom. Finally, it provides the function of stiffening.

Each rib performs the function of trapping the horizontal bond through one or two meshes at the ends. Furthermore, it provides the function of stiffening the part.

The lifting and handling eyes 9 are generally located on the inside of the lifting eyes so that they do not interfere with the assembly.

The various components described make it possible to build individual houses with a degree 9 seismic resistance from prefabricated parts at the factory and assembled on site.
