Description

The invention relates to a wall with integrated formwork which comprises at least one connecting means which is deployable and which is configured to connect this wall with integrated formwork to another similar and juxtaposed wall with integrated formwork. This invention also relates to a connection kit which is for a wall with integrated formwork and which is for connecting such a wall with integrated formwork to another similar and juxtaposed wall with integrated formwork.

This invention relates to the field of construction and, more particularly, to the field of the manufacture of walls with integrated formwork which are manufactured in the factory, transported to a site, and installed on this site with a view to erecting a construction.

We know, already and through the document EP2873781 , a wall with integrated formwork which comprises, on the one hand, two parallel and spaced apart skins and, on the other hand, means for connecting these two skins which adopt the form of a frame comprising external parts which extend between the two skins as well as internal parts which each extend inside one of the two skins. Such a wall with integrated formwork further comprises, on the one hand, deployable connecting means which are movable between a retracted position and a deployed position and, on the other hand, systems for mounting these connecting means on the means connection.

It will be observed that these mounting systems comprise elastic cables as well as fixing means, which adopt the form of ligatures, and which are configured to fix such an elastic cable, on the one hand, on a connecting means, more particularly on a part of such a connecting means which extends outside the wall with integrated formwork and, on the other hand, on the internal parts of the frame of the connecting means. Fixing such an elastic cable by means of such fixing means is particularly long and tedious. In addition, such an elastic cable is fixed to the internal parts of the frame of the connecting means, which requires fixing such an elastic cable to these connecting means before producing the two skins of the wall with integrated formwork in the factory. Such an elastic cable can in no way be fixed after the manufacture of the wall with integrated formwork in the factory, nor, a fortiori, before or after transporting such a wall with integrated formwork to a construction site. Finally, such an elastic cable is secured to the wall with integrated formwork and cannot be removed in any way, in particular when it proves necessary to dismantle this wall with integrated formwork.

The present invention seeks to remedy the drawbacks of walls with integrated formwork of the state of the art.

The present invention relates to the field of construction and, more particularly, the field of the manufacture of walls with integrated formwork which are manufactured in the factory, transported to a site, and installed on this site with a view to erecting a construction.

Such a wall with integrated formwork (1; 1') comprises two skins (2, 3) which are arranged opposite one (2; 3) to the other (3; 2), which are substantially parallel, and which are spaced apart so as to define between them an internal volume 4 on the wall (1; 1). These skins (2; 3) are usually made from a hydraulic mixture (in particular concrete) and/or by molding inside a mould.

According to a particular embodiment not shown, such a wall with integrated formwork (1; 1) may also comprise at least one layer of a thermally insulating material which equips the internal face of at least one of the two skins. (2; 3). Such a wall with integrated formwork (1; 1') is then usually known under the name of wall with integrated formwork and thermal insulation.

For reasons of simplification, in the rest of the description, reference will be made to a wall with integrated formwork (1; 1') knowing that this denomination corresponds both to a wall with integrated formwork (1; 1') devoid of layer of thermally insulating material than to a wall with integrated shuttering and thermal insulation.

Such a wall with integrated formwork (1; 1') also comprises at least one connection means 5 which is configured to connect these two skins (2; 3) together. In fact, such a wall with integrated formwork (1; 1') comprises a plurality of these connection means 5.

Such a connection means 5 can take the form of a rod which has, on the one hand, two end portions, one of which is anchored in one 2 of the two skins (2; 3) and the other is anchored in the other 3 of the two skins (2; 3) and, on the other hand, an intermediate portion which extends between the two end portions as well as inside the internal volume 4 of the wall with integrated formwork (1; 1').

As seen in the appended figures, such a connection means 5 can also take the form of a frame 50 which comprises, on the one hand, a first portion 51 which extends inside the one 2 of the two skins (2; 3), on the other hand, a second portion 52, which extends inside the other 3 of the two skins (2; 3), and which is parallel to the first portion 51, on the other hand again, a third portion 53, which is in the extension of the first portion 51 and of the second portion 52, which is perpendicular to this first portion 51 and to this second portion 52, which comprises a first part which extends inside one 2 of the two skins (2; 3), which comprises a second part which extends inside the other 3 of the two skins (2; 3) and which comprises a third part which extends between the first part and the second part of this third portion 53 as well as inside the internal volume 4 of the wall with integrated formwork (1; 1') and, on the other hand also, a fourth portion (not shown), which is in the extension of the first portion 51 and of the second portion 52, which is perpendicular to this first portion 51 and to this second portion 52, which is parallel to the third portion 53, which comprises a first part which extends inside one 2 of the two skins (2; 3), which comprises a second part which extends inside the other 3 of the two skins (2; 3) and which comprises a third part which extends between the first part and the second part of this fourth portion as well as inside the internal volume 4 of the wall with integrated formwork (1; 1').

The wall with integrated formwork (1; 1') further comprises at least one connecting means 6 which is configured to connect this wall with integrated formwork 1 to another wall with integrated formwork 1' similar and juxtaposed ( figure 2 ).

Said at least one connecting means 6 has, on the one hand, a retracted configuration ( figure 9 ) in which at least a part (or even, and preferably, all) of such a connecting means 6 is retracted inside the wall with integrated formwork (1; 1'), more particularly inside of the internal volume 4 of this wall with integrated formwork (1; 1') and, on the other hand, a deployed configuration ( figures 1 to 7 ) in which at least a part of such a connecting means 6 is deployed outside the wall with integrated formwork (1; 1'), more particularly outside the internal volume 4 of this wall with integrated formwork ( 1; 1'). In this deployed configuration, such a connecting means 6 extends laterally with respect to said wall with integrated formwork (1; 1'), more particularly laterally with respect to a lateral edge 10 that such a wall with integrated formwork (1; 1') and from such a side edge 10.

In fact, said at least one connection means 6 comprises a first part 60 (more particularly an internal part) which extends inside the internal volume 4 of this wall with integrated formwork (1; 1'), this in retracted configuration and in deployed configuration of such a connecting means 6.

Said at least one connecting means 6 also comprises a second part 61 (more particularly a mixed part) which extends laterally and externally with respect to this wall with integrated formwork (1; 1') as well as in the extension of the internal volume 4 of this wall with integrated formwork (1; 1'), and which is intended to extend inside the internal volume of said other wall with integrated formwork (1'; 1), this in the deployed configuration of said at least one connecting means 6. In the retracted configuration of said at least one connecting means 6, this second part 61 extends at least partly (or even entirely) inside the internal volume 4 of this wall with integrated formwork (1 ; 1').

In this regard, it will be observed that such a connecting means 6 is configured to pass from a retracted configuration to an extended configuration (and vice versa), this during the installation of the wall with integrated formwork (1; 1 ') next to the other formwork wall (1'; 1) as shown picture 2 . In fact, during this installation, said wall with integrated formwork (1; 1') adopts a downward movement with respect to the other wall with integrated formwork (1'; 1). During this downward movement, said at least one connection means 6 of the wall with integrated formwork (1; 1') bears against said at least one connection means 5 that the other wall with integrated formwork (1'); 1) which, under the effect of the downward movement of the wall with integrated formwork (1; 1'), causes the passage of such a connecting means 6 from an extended configuration to a retracted configuration. By continuing the downward movement of the wall with integrated formwork (1; 1'), said at least connecting means 6 exceeds said connecting means 5 and no longer rests against this connecting means 5. Said at least connecting means 6 passes , then, from the retracted configuration to the deployed configuration.

Another characteristic relates to the fact that the wall with integrated formwork (1; 1') comprises at least one mounting system 7 which is configured to mount said at least one connecting means 6 on said at least one connecting means 5.

Preferably, such a mounting system 7 is configured to mount said at least one connecting means 6 on the rod (in particular on the intermediate part of this rod) of such a connecting means 5 or on the frame 50 of such a connection means 5 (more particularly on the third portion 53 of the frame 50 of such a connection means 5, in particular on the third part of this third portion 53).

According to the invention, said at least one connection means 6 comprises at least one elastic plate (8; 8') which comprises, on the one hand, a stationary part 80 which is stationary with respect to said at least one connection means 5 , more particularly with respect to the rod (in particular with respect to the intermediate part of this rod) or to the frame 50 (more particularly with respect to the third portion 53 of the frame 50 of such a connection means 5, in particular with respect to the third part of this third portion 53) of such a connection means 5 and, on the other hand, a movable part 81 which is movable relative to the stationary part 80 of the said at least one elastic plate (8; 8' ), and, therefore, with respect to said at least one connection means 5.

The elastic character of such an elastic plate (8; 8') advantageously allows the mobile part 81 of this elastic plate (8; 8'), on the one hand, to be deformed (in particular so that said au least one connecting means 6 can pass from an extended configuration to a retracted configuration) and, on the other hand, to regain its shape (in particular so that said at least one means of link 6 can pass from a retracted configuration to a deployed configuration, more particularly after having made it adopt a retracted configuration).

Thus, the stationary part 80 of said at least one elastic plate (8; 8') is stationary relative to said at least one connection means 5.

This being said, said at least one assembly system 7 then comprises immobilization means 70 which are configured to immobilize the immobile part 80 of said at least one elastic plate (8; 8') with respect to said at least one means of connection 5, more particularly with respect to the rod or to the frame 50 (more particularly with respect to the third portion 53 of the frame 50, in particular with respect to the third part of this third portion 53) of such a connection means 5.

Such immobilization means 70 then comprise means for immobilizing in rotation 71 which are configured to immobilize the immobile part 80 of said at least one elastic plate (8; 8'), this in rotation with respect to said at least a connection means 5, more particularly on said at least one connection means 5. In fact, such means for immobilizing in rotation 71 are, more particularly, configured to immobilize the immobile part 80 of said at least one elastic plate ( 8; 8'), this in rotation around an axis along which said at least one connecting means 5 extends, more particularly the rod of such a connecting means 5 or the third portion 53 of the frame 50 (in particular the third part of this third portion 53) of such a connection means 5.

According to a first embodiment, these means for immobilizing in rotation 71 comprise, on the one hand, at least one housing 710 that comprises the immobile part 80 of said at least one elastic plate (8; 8') and, on the other hand, on the other hand, at least one key 711 which, each, is fixed with respect to said at least one connecting means 5, and which is housed inside said at least one housing 710.

According to a particular embodiment illustrated in the appended figures, such rotational immobilization means 71 comprise, on the one hand, a plurality of housings 710 that the immobile part 80 of said at least one elastic plate (8; 8 ') and, on the other hand, a plurality of keys 711 which, each, is fixed relative to said at least one connecting means 5, and which is housed inside one of said housings 710.

As visible in the appended figures, said at least one housing 710 can be constituted by a through opening ( figures 3 to 6 ) that comprises the stationary part 80 of said at least one elastic plate (8; 8') or by a notch ( figure 7 ) that comprises (in particular laterally) the stationary part 80 of said at least one elastic plate (8; 8').

In particular, said at least one key 711 (in particular each of said keys 711) can be constituted by a bar 9 (in particular metallic) which extends in a direction which is parallel to the lateral edge 10, which comprises the wall with integrated formwork (1; 1'), and from which extends the second part 61 of said at least one connecting means 6, this in the deployed configuration of said at least one connecting means 6.

As seen on the figures 3 to 7 in the appendix, such a bar 9 extends in a direction which is perpendicular to a direction in which said at least one connection means 5 extends (more particularly the rod or the third portion 53 of the frame 50 of such means connecting 5) and / or which is perpendicular to a direction in which extends said at least one connecting means 6 when the latter is in the deployed position.

According to a particular embodiment, the wall with integrated formwork (1; 1') comprises, on the one hand, a plurality of connection means 5 (which have the characteristics described above), on the other hand, a plurality of connecting means 6 (which have the characteristics described above), on the other hand again, a plurality of mounting systems 7 which are each configured to mount one of said connecting means 6 on one of said connection means 5 (this as described above).

In fact, these connection means 6 each comprise at least one elastic plate (8; 8'), which comprises a stationary part 80 and a mobile part 81, and which has the characteristics described above.

The assembly systems 7 then also each comprise means of immobilization 70 which comprise means of immobilization in rotation 71 which, on the one hand, are each configured to immobilize the immobile part 80 of the one of the elastic plates (8; 8') in rotation with respect to one of the connection means 5, this as described above and, on the other hand, comprise at least one housing 710 which comprises the stationary part 80 of such an elastic plate (8; 8') and at least one key 711 which is housed inside such a housing 710, this as described above.

In particular, the wall with integrated formwork (1; 1') comprises at least one bar 9 (in particular metallic) which comprises or which constitutes the keys 711 which comprise the means of immobilization in rotation 71 which comprise the means of immobilization 70 that includes at least part (or even all) of the mounting systems 7.

As mentioned above, such a bar 9 extends in a direction which is parallel to the side edge 10 of the wall with integrated formwork (1; 1').

The presence of such a bar 9 advantageously makes it possible to integrate within the same object (namely said bar 9) a plurality of keys 711, in particular the keys 711 that comprise the means of immobilization in rotation 71 that include means 70 for immobilizing a plurality of systems mounting 7 (or even all of these mounting systems 7) included in the wall with integrated formwork (1; 1').

According to other embodiments, these means for immobilizing in rotation 71 can also be constituted by at least one ligature, at least one bonding, at least one weld, at least one rivet, at least one staple or at least a clamp.

According to another characteristic, the immobilization means 70 further comprise means for immobilizing in translation 72 which are configured to immobilize the immobile part 80 of said at least one elastic plate (8; 8'), this in translation by relation to said at least one connecting means 5, more particularly to said at least one connecting means 5.

In fact, such means for immobilizing in translation 72 are, more particularly, configured to immobilize the immobile part 80 of said at least one elastic plate (8; 8'), this in translation in a direction parallel and/or perpendicular to an axis along which said at least one connection means 5 extends, more particularly the rod or the third portion 53 of the frame 50 (in particular the third part of this third portion 53) of such a connection means 5.

These means for immobilizing in translation 72 may comprise at least one rider 720, on the one hand, which is positioned astride around at least a part of said at least one connection means 5, more particularly around the rod (in particular of the intermediate part of this rod) or of the third portion 53 of the frame 50 of such a connection means 5, in particular around the third part of this third portion 53.

It will be observed that it is, more particularly, the stationary part 80 of said at least one elastic plate (8; 8') which may comprise said at least one rider 720. Alternatively or additionally, said at least one rider 720 may fitting this immobile part 80 and/or extending this immobile part 80 with said at least one elastic plate (8; 8').
