Description

The present invention relates to a movable connecting element of two walls with integrated formwork. The invention also relates to an integrated formwork wall having at least one movable element for connecting the wall to another wall juxtaposed.

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 10 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 15 by 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 20 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. One solution to this problem has been provided by a second type of wall incorporating a movable armature designed to adopt a retracted position within this wall as well as an extended position in which this movable armature extends outside of this wall. 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 movable armature that includes such a wall can then extend inside the internal volume of the other juxtaposed wall, this to seam these two walls juxtaposed. This type of wall requires, however, to be able 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.

The present invention aims to overcome the disadvantages of integrated formwork walls of the state of the art. To this end, the invention relates to a movable connecting element of two walls with integrated formwork each comprising two skins and at least one means for connecting these two skins.

This movable element is characterized in that it comprises at least one member designed to mount this rotating member on a means for connecting the two skins of a wall formwork integrated. The invention also relates to an integrated form wall 20 comprising: two skins, arranged facing each other, in substantially parallel manner, 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 and juxtaposed wall, and having a first part extending inside the internal volume of this wall as well as a second part which, on the one hand and in deployed position 30 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 to the interior of the internal volume of this 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 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 movable member. Thus, the present invention relates to a movable member having a member adapted to mount this rotating member on a means for connecting the two skins of a wall integrated formwork.

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 rotational mounting of a movable element that includes an integrated form wall makes it easy to position such a movable element near a connection means that comprises another wall juxtaposed, which allows for effective sewing between these two walls juxtaposed. The fact that the member allowing such a rotational mounting is incorporated in the movable member advantageously makes it possible to avoid using an additional piece to ensure such rotational mounting. In addition, the fact that the mobile element incorporates such a member also 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 connecting means of two skins equipped with at least one movable element), or after manufacture of this wall (more particularly after hardening of the concrete constituting the two skins of this wall and by joining together at least one movable element of a connecting means ), or after having sent such a wall to 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. Additionally, the movable element comprises or receives a means for maintaining the member (which comprises this movable element) rotatably mounted on a means for connecting two skins. The presence of this holding means advantageously makes it possible to make this mobile element integral with this means for connecting two skins, this in spite of the rotational movements of this movable element. The movable element further comprises means for driving such a rotatable element, from a retracted position and to an extended position of this movable element. These drive means are constituted by a means for biasing said movable element towards its deployed position, this restoring means being constituted by the weight of at least a part of this movable element and / or by a position of the element for rotate this movable element on the means for connecting two skins of the wall, with respect to this movable element. Such return means advantageously makes it possible to avoid using a specific tool and / or to provide openings in the wall. 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.

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 similar wall and juxtaposed. This connecting element 6 is movable between, on the one hand, a retracted position (FIG. 4) in which this mobile element 6 is at least partially (or entirely) retracted inside the internal volume 4 of the wall 1 and, on the other hand, an extended position (FIGS. 1, 3 and 4) in which part of this movable element 6 extends laterally with respect to this wall 1, in the extension of the internal volume 4 of this wall 1, this in to extend inside the internal volume of another wall 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 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, d 1 and in the deployed position of the movable element 6, extends laterally relative to the wall 1, in the extension of the internal volume 4 of the wall 1, and is intended to extend inside the volume internal of another wall similar and juxtaposed. On the other hand and in the retracted position of the movable element 6, this second portion 62 extends at least partially inside the internal volume 4 of the wall 1. This second portion 62 has a free end 63 s' extending outside the internal volume 4 of the wall, this at least in the deployed position of the movable member 6. In this regard, it will be observed that the wall 1 is designed so that, in the rest position of the movable member 6 this movable element 6 adopts an extended position in which the second portion 61 of this movable element 6 extends completely outside the internal volume 4 of the wall 1. This advantageously allows the second part 61 of a such movable element 6 to be positioned appropriately and automatically in the internal volume of another similar wall and juxtaposed to the integrated formwork wall 1 comprising this movable element 6, this during the positioning of the wall 1 comprising this movable element 6, so jux taposed to this other wall as will be described below. As mentioned above, the integrated form wall 1 comprises at least one movable element 6 between a retracted position and an extended position. The integrated form wall 1 also comprises at least one member 7 designed to mount such a movable member 6 in rotation on a means 5 for connecting two skins (2; 3) of the wall 1, between such a retracted position and a such deployed position of this movable member 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 7 (in particular 2 as shown in Figures 2 to 5) to ensure the mounting of such a movable member 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) of an integrated form wall 1 comprises at least one cross member 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 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 that includes this means 5.

The invention relates, more particularly, to such a movable element 6 for connecting two integral formwork walls 1 each comprising two skins (2; 3) and at least one means (5) for connecting these two skins (2 3). According to the invention, it is, more particularly, such a movable element 6 which comprises, then, at least one member 7 designed to mount this mobile element 6 in rotation on a means 5 for connecting the two skins (2; 3) In fact, the member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2; 3) and that comprises the movable member 6, is constituted by a housing 70 within which is positioned such means 5 for connecting two skins (2; 3), more particularly a crosspiece 50 that includes such means 5 to connect.

In fact and as visible in the appended figures, such a hooking means 71 then defines a housing 70 for receiving such means 5 for connecting two skin (2; 3). According to a particular embodiment, the member 7 for mounting the mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) and that comprises this movable element 6, is constituted by a deformation of this movable element 6. In particular, this member 7 may consist of a deformation of a free end that comprises this movable member 6, in particular the free end 61 of the first portion 60 of the movable member 6 which extends to the inside of the internal volume 4 of the wall 1 (FIGS. 2 to 5). In this regard, it will be observed that such a deformation constitutes, then, a housing 70 as mentioned above and / or an attachment means 71 as mentioned above. According to another characteristic of the movable element 6, the latter comprises at least one elongated piece 8 comprising at least a part of the first part 61 and at least a part of the second part 62 of the movable element 6. Such a long-form piece 8 takes the form of a rod, a bar, a "U" -shaped piece (FIGS. 2 to 7 and 9), a frame (in particular a rectangular frame, FIG. 8) or the like. According to a first type of embodiment, it is more particularly this longiform piece 8 which can then comprise said member 7 which can then be constituted by a deformation (as mentioned above) of this longiform piece 8, more particularly by deformation of a free end of this longiform piece 8. However, such a movable element 6 may, again, comprise at least one additional piece 9, made integral with a longiform piece 8, and comprising at least the member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2; 3).

Such additional piece 9 can be secured to the long-form piece 8 by welding (FIGS. 6 and 7), by overmolding (FIG. 8) or otherwise depending on the nature of the materials of these pieces (long-form 8 and / or additional 9).

Also and according to a second type of embodiment, it is, more particularly, this additional piece 9 which comprises, then, at least one such member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2 3). Again, such a member 7 may be constituted by a housing 70 (as mentioned above) and / or an attachment means 71 (as mentioned above) and / or deformation (as mentioned above). above) and that includes, then, this additional piece 9. Such additional piece 9 (or even the member 7 that includes such an additional piece 9) can then adopt the shape of a hook (particularly welded to the piece longiforme 8 as visible in FIG. 6), a clip (in particular welded to the long-form piece 8 as shown in FIG. 7), a jumper (in particular welded to the long-form piece 8), a case (in particular molded onto the piece longiform 8 as shown in Figure 8) or other. According to another characteristic of the movable element 6, it comprises or receives a means 10 for holding the member 7 (which comprises the movable member 6) rotatably mounted on a means 5 for connecting two skins (2; ). According to a first type of embodiment, the movable element 6 comprises such a means 10 for holding the member 7 in rotation (Figures 2 to 9). According to a first embodiment (in particular visible in FIGS. 2 to 5), the means 10 for holding the member 7 of the movable element 6 rotatably mounted on the means 5 for connecting two skins (2; 3) is constituted by a opening that has the housing 70 of this member 7 and whose size is smaller than that of the means 5 for connecting two skins (2; 3) positioned inside the housing 70.

Such an embodiment advantageously prevents this means 5 to connect to disengage out of its housing 70. According to a particular embodiment, the size of the opening that this housing 70 presents and / or the flexibility of the element 6 may advantageously be defined so as to allow the introduction of force means 5 to connect two skins (2; 3) within this housing 70. According to a second embodiment, the means 10 to maintain the member 7 of the movable member 6 rotatably mounted on the means 5 for connecting two skins (2; 3) is constituted by a stop, extending inside the housing 70 and / or through the opening of this housing 70, and against which bears the means 5 for connecting two skins (2; 3). In fact, one solution is that such a stop takes the form of a redan means or the like. As mentioned above, the movable element 6 comprises a longiform piece 8. Also and according to a first case, it is, more particularly, such a longiform piece 8 of this movable element 6 which can then comprise on the one hand, at least one member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2; 3) and, on the other hand, at least one means 10 for holding the member 7 in rotation (Figures 2 to 5). However, this mobile element 6 may, again, comprise an additional part 9. Also and according to a second case, this additional part 9 comprises, on the one hand, 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, at least one means 10 for holding the member 7 in rotation (Figures 6 to 8). In this regard, it will be observed that such a means 10 for maintaining the member 7 (in particular an opening or a stop as mentioned above) may, again, be constituted by a deformation of the movable member 6, more particularly of said piece (As the case, additional 9 or longiform 8 as visible in Figures 2 to 5) that includes this movable element 6.

A particular embodiment consists in that the member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2; 3) and the means 10 for holding such a member 7 in rotation consist of by deformation (Figures 2 to 5). As mentioned above, such an additional piece 9 may be constituted by a hook, a clip, a jumper, a housing or the like. However, and according to yet another case, on the one hand, the elongated piece 8 of the movable member 6 comprises at least one member 7 for mounting the movable member 6 in rotation on a means 5 for connecting two skins (2 3) and, on the other hand, the additional piece 9 of this movable member 6 comprises at least one means 10 for holding the member 7 in rotation. Such may be the case for an additional piece 9, overmolded on the elongated piece 8, and having a stop, in particular in the form of a step (Figure 9), and constituting the means 10 for holding the member 7 in rotation. Thus, the additional part 9 of the movable 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 10 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 mobile element 6 receives such a means 10 to keep the member 7 in rotation. It is, more particularly, the piece (longiform 8 or additional 9) of the movable member 6 which then receives such means 10. Such a means 10 for holding the member 7 in rotation can, then, adopt 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 take the form of a plate or the like, provided with such a stop, and comprising an opening inside which is engaged a portion of the movable member 6, more particularly the free end 61 of this movable member 6 An additional feature is that the movable member 6 further comprises means for driving this mobile element 6 in rotation, this from a retracted position and to an extended position of this movable element 6.

A preferred embodiment consists in that these means for driving the mobile element 6 in rotation are constituted by a means for biasing the movable element 6 towards its deployed position, this when this movable element 6 has been previously brought out of its deployed position and towards a retracted position. According to a preferred embodiment of the invention, the means for biasing the movable member 6 is constituted by the weight of at least a portion of this movable member 6 and / or by a position of the member 7 for mounting in position. 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. An additional feature is that the movable element 6 is made of a metallic material, more particularly steel.

As mentioned above, this mobile element 6 (more particularly a long piece 8 that includes this movable element 6) takes the form of a rod, a bar, a frame (including rectangular, Figure 8), a "U" -shaped piece (Figures 2 to 7 and 9) or the like.

Thus, and according to a preferred embodiment of the invention illustrated in FIGS. 2 to 7 and 9, such a movable element 6 is in the form of a "U" -shaped part comprising 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 the mobile element 6 in rotation on a means 5 for connecting two skins (2; 3) of a wall 1, or even a means 10 for maintain this movable element 6 on such a means for connecting 5.
