Description

The present invention relates to an integrated form wall with two skins spaced and connected together.

This invention relates to the field of building and, more particularly, that of the manufacture, in the factory, walls intended to be routed to a site where they are used for the construction of a building, including housing.

As prefabricated wall, it is known, in particular, an integrated form wall comprising two skins, made of concrete or the like, arranged facing one another, substantially parallel and spaced so as to define between them a volume internal to the wall. It also comprises means for connecting the two skins and at least one structural armature extending at least within such skin.

When a building is constructed, such a wall is juxtaposed to a similar or identical wall, already installed on site, and the connection between these two walls is ensured.

To ensure such a connection, it is known to use a connecting armature, adopting substantially the shape of a basket, and which is engaged between the skins of the wall and inside the internal volume thereof, this at level of a side edge of such a wall.

In fact, a first solution is to equip such a wall with such a binding frame, so that part of this frame extends laterally out of the wall, this just before juxtaposing the wall to another wall already established on site.

A second solution is to juxtapose two walls before introducing such a binding frame, from the top of such a wall, between the two skins of one of these two walls and inside the internal volume of this wall , this near the side edge of this wall. After having introduced this binding frame inside the wall, it is moved in the direction of the wall juxtaposed and is made to penetrate this frame to inside the inner volume of this wall juxtaposed, this so that this frame extends simultaneously in the internal volumes of these two walls. In this regard, it will be observed that the displacement of this connecting armature can be ensured by intervening on it through lights made in at least one skin of the wall inside which is introduced the armature.

Whatever the solution envisaged, this one requires the evaluation (more particularly the quantity) of the quantity of reinforcement of connection corresponding to a nomenclature of allocation of the walls to be equipped, the order of such reinforcements, the delivery according to the order and in due time, the storage of these frames usually delivered in bulk and the management of their stock, the mobilization of an operator for the establishment of such a frame, even the control of such an establishment a fortiori appropriately.

In addition and in accordance with the above-mentioned second solution, the introduction of such a connecting reinforcement into a wall from the top of a wall can be difficult or impossible because of the dimensions of the wall. this wall, variations in the thickness of the skins and / or the presence of obstacles (lifting hooks, means of connection, openings ...). In addition, after introduction of such a connecting armature inside such a wall, the displacement of this armature towards the wall juxtaposed may present difficulties because of a reduced access to such a frame through the walls. lights of the skin and / or the presence of obstacles on the trajectory of this frame.

It is, also, known documents DE 21 39 197 and GB-2,444,637 walls with integrated formwork comprising, on the one hand, two skins, disposed opposite and spaced so as to define an internal volume, on the other hand, means for connecting these two skins and, secondly, at least one connecting armature of this wall with another wall juxtaposed. Such a connecting armature comprises a first part extending inside the wall and a second part, integral with the first part, extending outside the wall, laterally with respect to the edge of the wall and in the extension of the internal volume thereof.

When building a building, it is appropriate to position such a wall juxtaposed with another wall, including similar or identical. The presence of the second part of the connecting reinforcement considerably complicates such a positioning, since it is necessary, as the case may be, to engage this second part of the reinforcement of a wall inside the internal volume. the other wall or position the two skins of a wall on either side of the second part of the frame of another wall, while handling the entire wall. Such positioning is made even more complex by the variations in the thickness of the skins and / or in the width of the internal volume of the other wall as well as by the presence of obstacles, more particularly constituted by connection means, and even still by binding frames of this other wall.

The present invention is intended to overcome the disadvantages of the walls of the state of the art.

• deux peaux, réalisées en béton ou analogue, disposées en regard l'une de l'autre, de manière sensiblement parallèle et espacée en sorte de définir entre elles un volume interne au mur ;
• des moyens de raccordement de ces deux peaux entre elles ;
• au moins une armature de structure s'étendant au moins à l'intérieur d'une peau ;
• au moins une armature pour la liaison de ce mur avec un autre mur similaire et juxtaposé, cette armature de liaison comportant, d'une part, une première partie s'étendant à l'intérieur de ce mur et, d'autre part, une seconde partie), solidaire de la première partie, s'étendant à l'extérieur de ce mur, latéralement par rapport au bord de ce mur et dans le prolongement du volume interne de celui-ci.

For this purpose, the invention relates to an integrated formwork wall comprising:

• two skins, made of concrete or the like, disposed facing one another, substantially parallel and spaced so as to define between them a volume internal to the wall;
• means for connecting these two skins together;
• at least one structural frame extending at least inside a skin;
• at least one armature for connecting this wall with another similar and juxtaposed wall, this connecting armature comprising, on the one hand, a first part extending inside this wall and, on the other hand, a second part), integral with the first part, extending outside this wall, laterally with respect to the edge of this wall and in the extension of the internal volume thereof.

This integrated shuttering wall is characterized in that the connecting armature comprises, on the one hand, a structure constituting the first part of this connecting armature and extending at least inside the internal volume of this wall, or even within at least one skin of the wall and, secondly, at least one element, associated with the structure, constituting the second part of this binding frame, and movable between a retracted position at least partly inside the wall and a deployed position outside this wall.

The wall according to the present invention has the advantage of being equipped, directly during its manufacture in the factory, a connecting armature. This advantageously makes it possible to avoid any logistical problem specific to the supply of the binding reinforcement site as well as any problem of stock management of these reinforcements at this site. In addition, the fact of equipping the factory wall with such a frame advantageously makes it possible to accelerate the construction of a building by eliminating the step (tricky, long, difficult, if not impossible) of setting up the building. such a frame on site. In addition, this invention advantageously makes it possible to make the construction of the building more reliable by eliminating the risk of non-quality resulting either from the omission of the introduction of a connection reinforcement in the wall, or from the use of a nomenclature reinforcement not appropriate for a wall with certain characteristics.

Finally, the wall according to the invention is provided with a connecting armature comprising a movable element between a retracted position at least partly inside the wall and a deployed position outside of this wall. The presence of this mobile element advantageously makes it possible, on the one hand, to easily position such a wall in the immediate vicinity of another wall, this in the final position adopted by this wall within the building, according to a positioning method. usual, then that this movable element is in the retracted position. On the other hand and after such positioning, the presence of this movable element makes it possible to move the movable element of the connecting armature of this wall, or of this other wall, respectively, to engage this mobile element inside the volume. internal of the other wall, respectively of this wall.
