Description

The present invention relates to a wall formwork integrated with at least one movable element to connect the wall to another wall juxtaposed. The invention also relates to a kit for producing such an integrated formwork wall and comprising a plurality of these movable elements.

The invention relates to the field of the building and, more particularly, that of the factory manufacture of walls intended to be conveyed to a site where they are located as part of the construction of a building.

Already known, such integrated formwork walls comprising or receiving movable elements designed to ensure the connection between two walls juxtaposed.

In fact and according to a first type of wall, such a movable element is engaged in the internal volume of two walls juxtaposed, this at the junction between these two walls and the top of these walls. A first disadvantage of such a type of wall consists in that it comprises means for connecting together the two skins of such a wall and in that the presence of these connection means hampers the progression of a movable element. during his engagement in the internal volume of these walls. Another disadvantage is that this type of wall is only suitable for the construction of buildings outside seismic zones in which it is necessary to sew two walls juxtaposed, this by performing an overlap between the frames of these two walls juxtaposed.

A solution to this problem has been provided by a second type of wall incorporating a movable armature designed to adopt a retracted position inside the wall as well as an extended position in which this mobile armature extends outside this wall. , laterally with respect to this wall, and in the extension of the internal volume of this wall. In the case of two walls juxtaposed, the mobile armature that includes such a wall can then extend inside the internal volume of the other wall juxtaposed, this to seam these two walls juxtaposed. This type of wall requires, however, to ensure the displacement by shifting of such a movable armature, this from a retracted position to an extended position. To do this, such a wall is provided with openings allowing the introduction, inside this wall, of a tool designed to ensure such a displacement. This type of wall has, however, many disadvantages. In particular, to carry out such a displacement, it is necessary to resort to a specific tool, to provide openings in the walls requiring subsequent intervention to ensure closure, besides such a displacement can be hampered by the presence of means to connect the two skins of each of these walls.

In the document US 2005/155306 , there is described a device designed to ensure the junction between two forms, each having two expanded polystyrene plates, parallel and spaced, and a plurality of means for connecting these two plates together. Such a joining device takes the form of a clip and comprises, on the one hand, a first end provided with a first attachment means and, on the other hand, a second end, opposite to the first end, and provided with a second attachment means. The establishment of such a clip consists, in a first step, to achieve the attachment of the first hooking means of this clip on a connecting means that includes a first form and, in a second step, to clip the second hooking means of this clip on a means for connecting that has a second shape, this to ensure the junction between these two forms and the clamping of these two forms together.

Such a device has many disadvantages.

In particular, this device requires an adjusted sizing of the clip as well as precise positioning, on the one hand, of the two forms relative to one another and, on the other hand, means for connecting, each with respect to the form that he equips. In addition, such a staple can be put in place on two shapes only after positioning so juxtaposed or superimposed of these two forms. In addition, this installation must be performed manually and by exerting a considerable effort to perform the clipping of the second attachment means, this to ensure the tightening of both forms. Additionally and because of the necessary handling of such a staple, the establishment of such a staple can be made only near the (lateral, respectively upper or lower) end of an edge (upper, respectively lateral) of a shape, this in immediate border of such a form. The junction between two forms is, therefore, made only punctually and only near the end of such an edge of such a shape which generates a junction fault between the two forms elsewhere than near the end of such an edge, especially over the rest of the length of the edge of such a shape. Finally, such a staple is simply hooked on a means for connecting so that a simple handling error can lead to a stall of this staple which then falls into the bottom of the internal volume of a form causing its loss without possibility of recovery .

The present invention aims to overcome the disadvantages of integrated formwork walls of the state of the art.

• deux peaux, disposées en regard l'une de l'autre, de manière sensiblement parallèle, et espacées en sorte de définir entre elles un volume interne au mur,
• des moyens pour raccorder ces deux peaux entre elles ;
• au moins un élément, mobile entre une position escamotée et une position déployée, conçu pour relier ce mur à un autre mur similaire et juxtaposé, et comportant une première partie s'étendant à l'intérieur du volume interne de ce mur ainsi qu'une deuxième partie qui, d'une part et en position déployée de l'élément mobile, s'étend latéralement et extérieurement par rapport à ce mur, dans le prolongement du volume interne de ce mur, et destinée à s'étendre à l'intérieur du volume interne de cet autre mur et, d'autre part et en position escamotée de l'élément mobile, s'étend au moins en partie à l'intérieur du volume interne de ce mur.

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

• two skins, arranged facing each other, 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 element, movable between a retracted position and an extended position, designed to connect this wall to another similar wall and juxtaposed, and having a first portion extending inside the internal volume of the wall and a second part which, on the one hand and in the deployed position of the movable element, extends laterally and externally with respect to this wall, in the extension of the internal volume of this wall, and intended to extend inside the internal volume of the other wall and, secondly and in the retracted position of the movable element, extends at least partly inside the internal volume of this wall.

This wall formwork integrated is characterized in that it comprises at least one member designed to mount such a rotating member on a means for connecting the two skins of the wall, this between a retracted position and an extended position of this element mobile.

The invention also relates to a kit for producing an integrated formwork wall having the characteristics mentioned above and comprising a plurality of movable elements.

Thus, the present invention relates to an integrated formwork wall having at least one member movable in rotation between a retracted position and an extended position.

Such a rotational movement considerably facilitates the movement of such a movable element between its retracted position and its deployed position, with respect to a displacement by shifting according to the state of the art.

In addition, the wall comprises at least one means for driving at least one movable element in rotation, from a retracted position and to an extended position of this movable element. Such a drive means is constituted, as the case may be, by a means (consisting of the weight of at least a part of this movable element and / or by a position of the member for rotating this movable element on the means for connecting two skins of the wall) to recall this movable element or by at least one pulling accessible from outside the wall. This avoids, advantageously, to use a specific tool and / or to provide openings in the wall. This also makes it possible to deploy a mobile element in the deployed position inside the internal volume of at least one wall, in particular in places inaccessible to the human hand or for a tool.

In addition, the rotation of a movable element that comprises a wall according to the invention makes it easy to position such a device. mobile element near a connection means (more particularly in support against such a connecting means) that comprises another wall juxtaposed, which allows for an effective seam between these two walls juxtaposed.

It will be observed that such a movable element is rotatably mounted on a means for connecting two skins of a wall, by means of said member for mounting such a member movable in rotation on such connecting means.

This feature advantageously makes it possible to equip with at least one such movable element an integrated formwork wall, either during its manufacturing process (in particular by directly using connection means of two skins equipped with at least one mobile element), either after manufacture of this wall (more particularly after hardening of the concrete constituting the two skins of this wall and by joining at least one movable element of a connection means), or again after having conveyed such a wall on a construction site.

This feature then makes it possible, advantageously, to equip, with at least one movable element, an existing integrated formwork wall, in particular of traditional design. This allows, in particular, to equip, with at least one movable element, an integrated formwork wall initially intended for use in non-seismic zone to make it advantageously usable for use in seismic zone.

A particular embodiment consists in that the member designed for rotational mounting takes the form of a complementary piece consisting of a ligature or a ball joint equipping the movable member.

However, and according to an advantageous embodiment, it is, more particularly, the movable element which comprises the member designed for rotational mounting (this member can, then, be incorporated in the movable element or equip it ) which advantageously makes it possible to avoid using a complementary part to ensure such rotational mounting.

Additionally, the integrated form wall includes means for holding the mounted movable member rotation on a means for connecting two skins. In fact, it is, more particularly, either the movable element which comprises or which receives such a means for maintaining, or the member for the rotational assembly which constitutes such a means for maintaining. The presence of this holding means advantageously makes this movable element integral with this means for connecting two skins, this in spite of the rotational movements of this movable element and / or the movements of the wall.

The integrated form wall may comprise a plurality of movable elements distributed over the entire height of such a wall. This allows, advantageously, to make a connection and a seam between two walls, this on the entire height of these two walls.

Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

The present invention relates to the field of the building and, more particularly, that of the manufacture of walls with integrated formwork.

In known manner, such integrated wall form 1 comprises two skins (2; 3), arranged facing one (2; 3) of the other (3; 2), substantially parallel, and spaced so to define between them an internal volume 4 on the wall 1.

Such skin (2; 3) can be made of wood or the like. Such a skin (2; 3) may, again, be made of a hydraulic material, more particularly of concrete or the like. According to another characteristic, such a skin (2; 3) can incorporate at least one structural reinforcement (more particularly in the form of a lattice resulting from an assembly of a plurality of bars, in particular metal).

Such integrated formwork wall 1 comprises, again, means 5 for connecting these two skins (2; 3) between them.

Such means 5 for connecting these two skins (2; 3) between them comprises at least one cross member (50; 50 '), on the one hand, extending along an axis perpendicular to the planes of these two skins (2; ) and, on the other hand, having two ends, one of which is associated with a skin 2 of the wall 1 while the other is associated with the other skin 3 of this wall 1.

In this regard, it will be observed that such an end may, then and as the case may be, be embedded in the skin (2; 3) of such a wall 1 when the latter (2; 3) is made of a hydraulic material or be made integral (directly or indirectly) with such a skin (2; 3), especially by screwing gluing or other, when the skin (2; 3) is made of wood or the like.

In fact, such means 5 for connecting these two skins (2; 3) may be constituted by a connector at least partly constituted by a cross member (50; 50 ') as mentioned above.

Such a means 5 for connecting these two skins (2; 3) may also be constituted by a staple adopting a "U" shape and having, on the one hand, two parallel branches, one of which is associated (embedded or secured as aforesaid) to a skin 2 of the wall 1 while the other is associated with the other skin 3 of the wall 1 and, secondly, a cross, connecting these two parallel branches, and having the characteristics mentioned therein. -above.

Finally, such a means 5 for connecting these two skins (2; 3) can be constituted by a binding armor adopting the shape of a basket or a basket ( figures 5 , 12 to 14 ). Such a connecting armature comprises, on the one hand, a plurality of bars parallel to each other, arranged in the form of a parallelogram (in particular rectangle or square), and some of which are associated (embedded or secured as mentioned above) to a skin 2 of the wall 1 while the others are associated with the other skin 3 of the wall 1. Such a connecting armature further comprises means for connecting these bars together. These connection means take the form of a plurality of frames or the like, made by folding a bar, extending in a plane perpendicular to the parallel bars and made integral with these parallel bars. Such a frame incorporates at least one cross member having the characteristics mentioned above and for connecting two skins (2; 3).

According to another characteristic of the integral form wall 1, it comprises at least one element 6 designed to connect the wall 1 to another wall 1 'similar and juxtaposed.

This element 6 is movable between, on the one hand, a retracted position ( figures 4 , 5 , and 13 ) in which this movable element 6 is at least partially (or entirely as illustrated) figure 4 ) retracted inside the internal volume 4 of the wall 1 and, on the other hand, an extended position ( Figures 1 to 3 , 12 and 14 ) in which a part of this movable element 6 extends laterally and externally with respect to this wall 1, in the extension of the internal volume 4 of the wall 1, this in order to extend inside the internal volume d 'another wall 1' similar and juxtaposed.

In fact and as can be seen in the appended figures, such a movable element 6 comprises a first part 60 extending inside the internal volume 4 of this wall 1, this as well in the retracted position as in the deployed position of this mobile element 6.

This first part 60 then comprises a free end 61 extending, then, also inside this internal volume 4.

This movable element 6 also comprises a second part 62 which, on the one hand and in the deployed position of the movable element 6, extends laterally with respect to this wall 1, outside this wall 1, in the extension of the internal volume 4 of the wall 1, and is intended to extend inside the internal volume of another wall 1 'similar and juxtaposed. On the other hand and in the retracted position of the movable element 6, this second part 62 extends at least in part (or even entirely as figure 4 ) inside the internal volume 4 of this wall 1.

This second portion 62 has a free end 63 extending outside the internal volume 4 of the wall 1, this at least in the deployed position of the movable member 6.

In this regard, it will be observed that, according to a first embodiment of the invention (illustrated figures 2 , 3 and 11 to 18 ) the wall 1 is designed so that, in the rest position of the movable element 6, this movable element 6 adopts an extended position in which the second portion 62 of this movable element 6 extends completely outside the internal volume 4 from this wall 1.

Such a type of embodiment advantageously allows the second part 62 of such a movable element 6 to be positioned appropriately and automatically in the internal volume of another similar wall 1 'and juxtaposed with the integrated formwork wall 1 comprising this movable element 6, this during the positioning of the wall 1 comprising this movable element 6 (first illustrated embodiment figures 2 and 11 to 18 ), respectively of this other wall 1 '(second illustrated embodiment figure 3 ), juxtaposed with this other wall 1 ', respectively to the wall 1 having such a movable member 6 as will be described below.

However, according to a second type of embodiment illustrated figures 4 and 5 , the wall 1 is designed so that, in the rest position of the movable element 6, this movable element 6 adopts a retracted position in which the second portion 62 of this movable element 6 extends integrally inside the internal volume 4 of this wall 1. Such an embodiment advantageously makes it possible to prevent such a mobile element 6 from extending outside the wall 1, in particular during the manufacturing and handling steps of such a wall 1.

As mentioned above, the integrated form wall 1 comprises at least one movable element 6 between a retracted position and an extended position.

According to the invention, the integrated formwork wall 1 also comprises at least one member 7 designed to mount such a movable element 6 in rotation on a means 5 for connecting two skins (2; 3) of the wall 1, this between a such a retracted position and such an extended position of this movable element 6.

In this regard, it should be noted that, depending on the nature of said movable member 6, the integrated form wall 1 may comprise, as the case may be, a single member 7 or a plurality of these members 7 (in particular 2 as visible Figures 2 to 5 , 9 to 18 ) to ensure the mounting of such a movable element 6 in rotation on such a connecting means 5.

As mentioned above, the integrated form wall 1 comprises at least one movable element 6. Also and according to a preferred embodiment of the invention, such a wall 1 comprises, in fact, a plurality of these movable elements 6 In addition, such an integrated form wall 1 usually comprises a plurality of means 5 for connecting the two skins (2; 3) between them. Also and in the case of a wall 1 comprising a plurality of movable elements 6, this wall 1 also comprises a plurality of members 7 to make such a movable element 6 integral in rotation with such means 5 to connect two skins (2; 3).

As mentioned above, such means 5 for connecting two skins (2; 3) comprises at least one cross member (50; 50 ') extending along an axis perpendicular to the plane of these two skins (2; 3).

That being said, said member 7 for mounting a mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) is, then, designed to allow rotation of this movable element 6 around the extension axis d such a cross member (50; 50 ') or about an axis parallel to this axis of extension, more particularly in a direction perpendicular to this axis.

According to another feature of the invention, such a mounting member 7 is, in fact, designed to allow free rotation of the movable member 6 relative to the means 5 to connect two skins (2; 3), more particularly by relative to a crossbar (50; 50 ') that comprises this means 5.

It has been illustrated Figures 1 to 10 a first family of walls 1 with integrated formwork. The integrated formwork walls 1 conforming to this first family comprise at least one movable element 6 and at least one element 7 designed to mount such a movable element 6 in rotation on a means 5 for connecting the two skins (2; such a wall 1.

In fact, according to this first family, said member 7 is constituted by a complementary piece (70; equipping said movable element 6 and / or said means 5 to connect the two skins (2; 3).

Also and according to a first type of realization illustrated figure 6 , said member 7 for mounting a mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) is constituted by a ligation 70, in particular implemented using a ligating gun and / or performed using a wire, more particularly a wire, for example a wire.

According to a second type of embodiment, such a member 7 for mounting a mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) is constituted by a ball 71.

Such a ball 71 comprises, on the one hand, a means 710 for receiving a means 5 for connecting two skins (2; 3), more particularly for receiving a crosspiece 50 that comprises such means 5 and which extends in a direction perpendicular to the planes of the skins (2; 3). In fact, this receiving means 710 is, more particularly, designed to allow rotation of the ball 71 with respect to this means 5 for connecting two skins (2; 3).

On the other hand, this ball 71 comprises means 711 for receiving a mobile element 6 extending in a determined direction, in particular perpendicular to the direction of extension of the means 5 for connecting two skins (2; 3), more particularly a crosspiece 50 that includes such means 5.

In fact, this receiving means 711 is more particularly designed to ensure immobilization of this movable element 6 with respect to said ball joint 71.

According to a first embodiment of this second illustrated embodiment figure 7 such a ball 71 takes the form of a jumper, in particular of the clipping type or the like, comprising, on the one hand, a bottom in which is positioned a means 5 for connecting two skins (2; 3) and constituting the means 710 for receiving such means 5 for connecting two skins (2; 3). In fact, the bottom of this jumper is designed to allow a rotation of this jumper relative to the means 5 to connect two skins (2; 3).

On the other hand, this jumper comprises two branches, connected together by the bottom, and provided with a means 711 for receiving a movable element 6.

In fact, this means 711 for receiving a movable member 6 is designed to ensure immobilization of such a movable member 6 with respect to this jumper. In this regard, it will be observed that this means 711 for receiving a movable member 6 is constituted by a notch whose shape and / or dimensions allow a tight engagement (and, therefore, immobilization) of a movable member 6 inside that cut.

According to a second embodiment of this second illustrated embodiment Figures 8 to 10 such a ball 71 takes the form of a plate having, on the one hand, a through opening through which is engaged a means 5 for connecting two skins (2; 3) and constituting the means 710 for the reception of such means 5 for connecting two skins (2; 3). In fact, this through opening is designed to allow a rotation of this plate relative to the means 5 for connecting two skins (2; 3).

On the other hand, this plate comprises a receptacle, fitted laterally on one side of the plate, and constituting the means 711 for receiving a mobile element 6.

In fact, this means 711 for receiving a movable member 6 is designed to ensure immobilization of such a movable member 6 relative to said plate.

According to another characteristic, this plate preferably adopts the shape of a disk.

Yet another feature is that said through opening is centrally formed with respect to the plate while the receptacle is laterally offset from the central opening.

Finally, the receptacle is constituted by a sleeve, or even (and preferably) by clipping means, more particularly defined by a sleeve having a slot longitudinal through which said movable member 6 is engaged within the receptacle.

As visible on the figure 8 , said through opening may be completed by a notch extending, more particularly diverging, from the through opening and towards the lateral edge of the plate.

This notch makes it possible, advantageously, to place the ball 71 on the means 5 to connect two skins (2; 3), this by engaging this connecting means 5 inside the cut-through to the opening .

In this regard, it will be observed that said ball 71 comprises a means for retaining the means 5 for connecting two skins (2; 3) within the through opening. Such means for retaining may be constituted by clipping means or the like, for example defined by a section of the through opening greater than the width of the notch at the outlet of this through opening.

It should be observed that the ball joints 71 described above are more particularly suitable for mounting on a means 5 for connecting two skins (2; 3) of a portion of a movable element 6 extending in one direction. perpendicular to the extension direction of this means 5 for connecting two skins (2; 3). In such a case, the means 710 for receiving a means 5 for connecting two skins (2; 3) and the means 711 for receiving a movable member 6 extend substantially in a perpendicular direction.

However, some embodiments (particularly that illustrated figure 2 and described in more detail below) consist in ensuring the mounting on a means 5 for connecting two skins (2; 3) of a portion of a movable member 6 (more particularly a crosspiece that comprises such a movable element 6 under form) extending in a direction parallel to such means 5. In such a case, the means 710 for receiving a means 5 for connecting two skins (2; 3) and the means 711 for the receiving a movable element 6 that includes such a ball 71 extend substantially according to a parallel direction. In addition, the means 710 for receiving a means 5 for connecting two skins (2; 3) and / or the means 711 for receiving a movable member 6 allow rotation of the swivel 71 relative to this means. 5 for connecting two skins (2; 3) and / or with respect to this movable element 6.

According to another characteristic of the invention, the wall 1 with integral formwork comprises at least one means 8 for holding such a movable member 6 on a means 5 for connecting two skins (2; 3). The presence of such a means 8 to maintain advantageously makes it possible to secure and retain such a movable element 6 and such a means 5 to connect, in spite of the rotation of this movable element 6 with respect to this means 5 for connecting and the handling of the wall 1.

In this regard, it will be observed that the means 8 for maintaining can then be constituted by the member 7 itself, more particularly by the ligature 70 or by the ball 71, in particular by means (710; 711) that has such a ball 71.

As regards said movable member 6, it is preferably made of a metallic material, more particularly steel.

This movable element 6 takes the form of a rod, a bar, a "U" -shaped piece, a frame (in particular rectangular as visible on the Figures 2 to 5 , 9 and 10 appended and corresponding to the preferred embodiment of the invention) or the like.

According to another characteristic of the invention, the integrated form wall 1 also comprises at least one means 9 for driving at least one mobile element 6 in rotation, from a retracted position and towards an extended position of this movable element 6.

According to a first type of embodiment illustrated figures 2 and 3 such means 9 for rotating in a deployed position at least one movable member 6 is constituted by means for biasing such a movable member 6 towards its deployed position, when such a movable member 6 has previously been brought out of its deployed position and towards a position (at least partly) retracted.

In fact, such a means for recalling this movable element 6 is constituted by the weight of at least a part of this movable element 6 and / or by a position of the member 7 to rotate this movable element 6 on a means 5 to connect two skins (2; 3) of the wall 1, with respect to this movable element 6.

According to this first embodiment, during the positioning of an integrated form wall 1 comprising such a mobile element 6 juxtaposed with another similar wall 1 ', the movable element 6 (more particularly the second part 62 of this element mobile 6) can cooperate with a means 5 'for connecting the two skins of the other wall 1'. Under the effect of this cooperation and a downward movement of the wall 1, the movable member 6 is moved out of its deployed position and to a position (at least partly) retracted. Continuing the downward movement of the wall 1, this cooperation is interrupted and the movable element 6 returns to its deployed position, this under the effect of the means for returning the movable element 6 to its deployed position (which is a position suitable for sewing between the two walls 1; 1 ') and automatically (under the effect of gravity).

However, and according to an additional feature of this first embodiment, the wall 1 with integrated formwork may also comprise at least one removable means for keeping at least one movable member 6 in the retracted position, this at least during the positioning of a wall 1 integrated formwork juxtaposed to another wall 1 'integrated formwork.

This means for keeping the movable element 6 in the retracted position prevents this movable element 6 from reaching its deployed position.

Such a means for keeping the movable element 6 in the retracted position can take the form of a vertical bar designed adapted to cooperate with said movable member 6, more particularly with a free end (61; 63) thereof 6, in particular by taking support and / or was fixed reversibly there.

Thus, this first portion 64 extends between the member 7 and the free end 63 of the second portion 62 of the movable member 6 while the second portion 65 extends between this member 7 and the free end 61 of the first portion 60 of the movable member 6.

In this second embodiment, the means for returning the movable element 6 is constituted by the weight of the second portion 65 of the movable element 6 which is greater than the weight of the first portion 62 of this movable element 6.

According to this second embodiment, when positioning in a manner juxtaposed with the integrated form wall 1 comprising such a movable element 6 of another integrated form wall 1 'similar, the movable element 6 (more particularly the second part 62 of this movable element 6) can cooperate with means for connecting the two skins of the other wall 1 '. Under the effect of this cooperation and a downward movement of the other wall 1 ', the movable member 6 is moved out of its deployed position and to a position (at least partly) retracted. By continuing the downward movement of this other wall 1 ', this cooperation is interrupted and the movable element 6 returns to its deployed position, this under the effect of the means for reminding this movable element 6 to its deployed position (which is a suitable position for sewing between the two walls 1; 1 ') and automatically (under the effect of gravity).

However, and according to an additional feature of this second embodiment, the wall 1 integrated formwork may, further comprise at least one removable means for keeping at least one movable member 6 in the retracted position, this at least during the positioning of a wall 1 integrated formwork juxtaposed to another wall 1 'integrated formwork. Such removable means has the same characteristics, the same functionality, and achieves the same result as mentioned above.

Again and alternatively, the wall 1 with integrated formwork can also include at least one means (of the aforementioned type) for driving at least one movable element 6 in rotation, this from an extended position and to a retracted position of this movable element 6.

As visible on the figures 2 and 3 , the integrated shuttering wall 1 according to this first embodiment further comprises means 10 for limiting the rotation of the driven movable element 6 (more particularly recalled) towards its deployed position by the means 9 to drive (more particularly to recall) such a movable element 6.

This means 10 for limiting the rotation completes the means for driving (recalling) the movable element 6 in the deployed position and is designed to retain the movable element 6 in its deployed position, this after such rotation from a retracted position of the movable element 6.

Such a means 10 for limiting the rotation may be constituted by a means 5 for connecting two skins (2; 3) to one another, more particularly a crossmember 51 other than that 50 on which is rotatably mounted said movable member 6, in particular a cross member. 51 that also comprises the connecting armature (basket, basket as mentioned above) comprising the cross member 50 on which is provided such a mounting.

Such a means 10 for limiting the rotation of the movable member 6 is designed so that in the deployed position, the movable member 6 extends substantially horizontally.

As mentioned above, the integral shuttering wall 1 comprises at least one means 9 for driving at least one movable element 6 in rotation, from a retracted position and towards an extended position of this movable element 6.

According to a second type of embodiment illustrated figures 4 and 5 such means 9 for driving towards an extended position at least one such movable element 6 is constituted by at least one tie rod 90 secured to at least one such movable element 6, extending inside the internal volume 4 of the wall 1, and accessible, even manipulable, from outside the wall 1.

Such tie 90 can be flexible (especially in the form of a string, a rope, a cable or other) or rigid (especially in the form of a rod or the like). Such a pull 90 can then be made of steel, fabric, plastic or other.

With regard to this second type of embodiment, it is characterized by a movable element 6 comprising a first portion 64 incorporating at least the second portion 62 (outer) of this movable member 6, or even (and preferably) a part of the first part 60 of this movable element 6.

Thus, this first portion 64 extends between the member 7 and the free end 63 of the second portion 62 of the movable member 6 while the second portion 65 extends between this member 7 and the free end 61 of the first portion 60 of the movable member 6.

The means 9 for rotating in a deployed position at least one movable element 6 is then secured to this second portion 65 of such a movable element 6.

According to another characteristic of this second embodiment, the wall 1 further comprises means for driving at least one movable element 6 towards its retracted position, starting from an extended position of this movable element 6.

In fact, such a means for driving at least one movable member 6 to its retracted position is constituted by a means for biasing this movable member 6 to its retracted position.

This means for returning is constituted by the weight of at least a part of this movable element 6 and / or by a position of the member 7 for rotating this movable element 6 on the means 5 to connect two skins (2; 3) of the wall 1, with respect to this movable element 6.

According to a preferred embodiment, the means for returning such a movable element 6 is constituted by the weight of the second portion 65 of this movable element 6 which is greater than the weight of the first portion 64 of this mobile element 6

In this regard, it will be observed that this means for biasing such a movable member 6 has the effect of driving the movable member 6 in its retracted position under the effect of gravity.

Thus, the means 9 for rotating at least one movable member 6 to an extended position acts against the means for driving such a movable member 6 to its retracted position which, because of the gravity, tends to reduce such a movable element 6 in its retracted position.

This means 9 for rotating at least one movable member 6 to an extended position is then actuated after positioning of an integrated form wall 1 comprising such a movable member 6, this juxtaposed with another wall 1 'to integrated formwork similar.

As mentioned above, the integrated form wall 1 according to the invention may comprise a plurality of movable elements 6. In such a case, said integral form wall 1 according to this second embodiment may be completed by at least one means 11 for interconnecting a plurality of movable elements 6.

In this regard, it will be observed that such a means 11 for connecting a plurality of movable elements 6 to each other may constitute a means 9 for driving (towards their deployed position or towards their retracted position) simultaneously in rotation a plurality of moving elements. 6 or, again, be completed by a means 9 (as mentioned above) for driving in rotation at least one such movable element 6.

Such a kit 12 can then advantageously be sold independently of a formwork wall of conventional design and set up on such a wall, especially on site. In particular, such a kit 12 can be put in place on walls that are suitable only for an application outside seismic zones which then become advantageously exploitable in seismic zones.

Finally, the invention may also relate to a connecting armature comprising, on the one hand, a basket or basket of traditional design and described above and, on the other hand, a plurality of movable elements 6 as well as a plurality of members 7 designed to mount such a movable element 6 in rotation on such a connecting armature, or even at least one means 9 for driving in rotation at least one movable element 6 and / or at least one means 11 for interconnecting at least a portion of the movable elements 6.

According to another characteristic, the wall 1 with integral formwork comprises at least one means 8 for holding a movable member 6 on a means 5 for connecting the two skins (2; 3). In this regard, it will be observed that it is, more particularly, the movable element 6 which comprises or receives such a means 8 to maintain this mobile element 6. In fact, such a means 8 to maintain is, more particularly, designed to maintain a member 7 (which comprises the movable member 6) rotatably mounted on a means 5 for connecting two skins (2; 3). As mentioned above, the presence of such a means 8 to maintain advantageously makes it possible to secure and retain such a movable element 6 and such a means 5 to connect, despite the rotation of this mobile element 6 by relative to this means 5 for connecting.

According to a first type of embodiment, the movable element 6 comprises such a means 8 for holding the member 7 in rotation ( Figures 11 to 18 ).

According to a first embodiment (in particular visible Figures 11 to 14 ), the means 8 for holding the member 7 of the movable member 6 rotatably mounted on the means 5 for connecting two skins (2; 3) is constituted by an opening that has the housing 72 of this member 7 and whose dimension is less than that of the means 5 for connecting two skins (2; 3) positioned inside this housing 72.

Such an embodiment advantageously prevents this means 5 for connecting to disengage from its housing 72.

According to a particular embodiment, the dimension of the opening that this housing 72 presents and / or the flexibility of the movable element 6 can advantageously be defined so as to allow the force introduction of the means 5 for connecting two skins (2; 3) inside this housing 72.

However, and according to another case, on the one hand, the elongated piece 66 of the mobile element 6 comprises at least one member 7 for mounting the mobile element 6 in rotation on a means 5 for connecting two skins (2 3) and, on the other hand, the additional piece 13 of this movable element 6 comprises at least one means 8 for holding the member 7 in rotation. Such may be the case for an additional piece 13, overmoulded or engaged (in particular by interlocking) on the longiform piece 66, and comprising a stop, in particular in the form of a redan ( figure 18 ), and constituting the means 8 for holding the member 7 in rotation.

Thus, the additional piece 13 of the mobile element 6 may comprise at least one member 7 for mounting the mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) and / or at least one means 8 for maintain such a member 7 rotatably mounted on the means 5 for connecting two skins (2; 3).

According to a second type of embodiment, the movable element 6 receives such a means 8 to keep the member 7 in rotation.

It is, more particularly, the piece (longiforme 66 or additional 13) of the movable element 6 which receives, then, such means 8.

Such a means 8 for holding the member 7 in rotation can then take the form of a stop (having the characteristics mentioned above) and that comprises a support associated with the movable member 6. Such a support can adopt the form of a plate or the like, provided with such a stop, and having an opening inside which is engaged a portion of the movable member 6, more particularly the free end 61 of this movable member 6

Thus and according to a preferred embodiment of the invention illustrated on the Figures 11 to 16 and 18 such a movable member 6 is in the form of a "U" -shaped piece with two branches and a connecting crossbar of these two branches.

These two branches each have a free end each comprising a member 7 for mounting this mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) of a wall 1, or even a means 8 for maintain this movable element 6 on such a means for connecting 5.
