Description

The present invention relates to a lost form insulating wall and a method of manufacturing such a wall.

This invention relates to the field of the building and, more particularly, to the manufacture, in the factory, of the insulating walls with lost formwork.

We already know, such walls insulating formwork with two skins, at least one insulating panel interposed between these two skins, at least one connecting means of these two skins, and at least one means of connection of the wall to a handling machine.

The manufacture of such a formwork wall insulation is done, in part, on a traditional chain formwork walls of conventional type and lacking insulation board.

In this regard, it will be observed that the method of manufacturing such a conventional formwork wall is to position, in a first mold, a frame of structure and to fix on it a first end portion that includes at least a sling constituting a connecting means. In this first mold, connection means are also positioned and concrete is poured in order to produce a first skin of the wall inside which the first end portion of the sling is embedded. A second end portion of the sling of the connection means is also fixed on another part of the same structural reinforcement (basket, beam) emerging out of the concrete of the first skin. Subsequently, the first skin is turned over and the connection means and the second sling end portion and the other part of the same are drowned inside a concrete cast in a second mold. structure frame. Finally, the cast concrete is dried in the second mold for producing the second skin of the wall.

The entire method of manufacturing such a formwork wall can be implemented on a chain Traditional. However, for an insulating wall with lost formwork, the presence of an insulating panel does not allow to implement the entire process of manufacturing such an insulating wall on such a traditional chain.

In fact, the method of manufacturing such a formwork insulating wall consists, firstly and on the traditional manufacturing line, on the one hand, to position a structural reinforcement and at least one connecting means of which one end is fixed to said structural reinforcement and, on the other hand, to pour concrete, this inside a first mold that comprises this production line and for obtaining an assembly which, in a second step, is removed from the production line for routing to a position of installation of at least one insulating panel.

At this station, the assembly is equipped with at least one connection means as well as with the insulating panel, this before setting up, above this insulating panel, a second frame of structure to which is fixed the other end of the connection means and for obtaining a first face. This first face is reintroduced into the production line for, after drying of the concrete of this first face, be returned and introduce at least the connection means or in a concrete poured inside a second mold of this chain of manufacturing, this to obtain the insulated wall formwork. After drying the concrete, this insulating wall with lost formwork is demolded and stored pending its delivery to the site.

This process has a number of disadvantages. Indeed, it will be observed that the second structural reinforcement, the connection means and the insulating panel are usually made and / or stored near the production line (especially in a room above this chain). manufacturing) or feed this production line via a traditional means of transport (in particular in the form of a conveyor or a hopper surmounting this production line). By setting up, at the level of a positioning station remote from the production line, such a second structural reinforcement, such or such means of connection and such an insulating panel, it is appropriate to route them to this position implementation (or even to store them) which is a tedious task, especially for said second structural armature because of its weight and its dimensions, or even the distance of the positioning station.

The present invention is intended to overcome the drawbacks of the manufacturing process of the state of the art, this through a lost form insulating wall of new design and through a new manufacturing process for manufacturing such a wall.

• inside the concrete poured into the same first mold or second mold, these two end portions are drowned. such a sling of such a connecting means and at least a portion of the frame or reinforcements on which or on which are fixed these two end portions of the sling of such connecting means.

Thus, the invention relates to a lost-form insulating wall comprising at least one connecting means each adopting the shape of a sling having two end portions which are embedded within the same skin of the wall and which are fixed on one or more structural armatures which are at least partly embedded within the same skin of the wall.

The presence of such a connecting means and its arrangement within the wall (flooding its two end portions in the same skin and fixing these two end portions on a frame embedded in the same skin) allow, advantageously, to facilitate the manufacture of such a wall.

The invention also relates to a method of manufacturing a lost-form insulating wall, this method consisting in embedding, in the concrete of at least one skin of the wall and inside the concrete of such a skin. the two end portions, which comprises at least one sling constituting a connection means for connecting the wall to a handling machine, between which is interposed an intermediate portion that includes such a sling and which is intended to cooperate with such a handling equipment.

This allows, advantageously and during the manufacturing process, to set up such a connecting means at such a skin, on the one hand, by fixing it on at least one frame of structure positioned or to position in a mold that includes the production line and, on the other hand, by embedding the two end portions of this connection means in a concrete cast inside the same mold, this during a production step of such a skin.

Advantageously, it is then possible to set up such a connecting means as well as the structural reinforcement or frames on which such connecting means is fixed, this within the same traditional production line (which is already fed at least in structural reinforcement) and without having, as in the state of the art, to route, store, and put in place, such a structural reinforcement at a remote station setting up an insulating panel.

In addition, the manufacturing method advantageously makes it possible to manufacture a wall of which only one skin, or even (and preferably), the two skins each comprise at least one connecting means.

Finally, the method according to the invention significantly simplifies the manufacture of an insulating wall formwork lost compared to the method of the state of the art.

This first type of embodiment makes it possible to obtain an insulating wall 1 conforming to the first type of embodiment described above and of which only one of the skins (4; 5) comprises a connection means (11; 12).

According to a second embodiment of this method, on at least one structural reinforcement (9; 10) positioned or positioned in the first mold or in the second mold, the two end portions (130; a plurality of slings (13; 14) each constituting a connecting means (11, 11 '; 12, 12') and these two end portions (130; 140) of slings (13; 14) and at least a part of the structural reinforcement or frames (9; 10) to which or on which these two end portions (130; 140) of slings (13; 14) are attached, this in the concrete poured into this first mold or into this second mold.

This second type of embodiment makes it possible to obtain an insulating wall 1 according to the second type of embodiment described above and of which at least one of the skins (4; 5) comprises a plurality of connection means (11, 11 '; 12 ').

According to a third embodiment, this method consists in that, on at least one structural reinforcement 9 positioned or positioned in the first mold, the two end portions 130 of at least one first sling 13 constituting a first connecting means (11, 11 ') and these two end portions 130 of sling 13 are drowned together with at least a part of the structural reinforcement (s) 9 on which these two portions are fixed. end 130 of sling 13, this in the concrete poured into this first mold. This third embodiment also consists in that, on at least one structural reinforcement 10 positioned or positioned in the second mold, the two end portions 140 of at least one second sling 14 constituting a second connecting means (12, 12 ') and these two end portions 140 of sling 14 are drowned and at least a portion of the frame or frames 10 on which or on which are fixed these two end portions 140 of sling 14, this in the concrete poured into the second mold.

Another feature of the method according to the invention consists in that before drowning the two end portions (130; 140) of the slings (13; 14) connecting means (11, 11 '; 12, 12') in the concrete (of the first mold, of the second mold), there are (in the first mold, in the second mold) these slings (13; 14) so that these connection means (11, 11 '; 12, 12' ) extend in parallel general directions.

Such a method of proceeding makes it possible to produce an insulating wall 1 in which the connection means (11, 12; 11 ', 12'), which the insulating wall 1 comprises, extend in a parallel manner, more particularly from the same side (3; 3 ') or beyond such a same side (3; 3') of such an insulating wall 1.

In particular, this makes it possible to produce an insulating wall 1 in which the connecting means (11, 11 ', 12, 12'), which comprises the same skin (4; 5), extend in a parallel manner, more particularly to from the same side (40, 40 ', 50, 50') or beyond such a same side (40, 40 ', 50, 50') of a such skin (4; 5). Such a procedure also makes it possible to produce an insulating wall 1 in which the connection means (11, 11 ', 12, 12') which comprise two skins (4; 5) extend in parallel, more particularly from two sides (40, 40 ', 50, 50') parallel to or beyond two parallel sides (40, 40 ', 50, 50') of these two skins (4, 5).

Alternatively, before drowning the two end portions (130; 140) of the slings (13; 14) connecting means (11, 11 '; 12, 12') in the concrete (of the first mold; mold), there are (in the first mold, in the second mold) these slings (13; 14) so that these connection means (11, 11 '; 12, 12') extend in perpendicular general directions.

Such a method of proceeding makes it possible to produce an insulating wall 1 in which the connection means (11, 12; 11 ', 12'), which the insulating wall 1 comprises, extend in a perpendicular manner, more particularly from two consecutive sides (3; 3 ') that this insulating wall 1 comprises.

In particular, this makes it possible to produce an insulating wall 1 in which the connecting means (11, 11 ', 12, 12'), which comprises the same skin (4; 5) of the insulating wall 1, extend perpendicularly. , more particularly from two successive sides (40, 40 ', 50, 50') of such a skin (4; 5) or beyond two consecutive sides (40, 40 ', 50, 50') d such skin (4; 5). Such a procedure also makes it possible to produce an insulating wall 1 in which the connecting means (11, 11 ', 12, 12') which comprise two skins (4; 5) extend perpendicularly, more particularly from two consecutive sides (40, 40 ', 50, 50') or beyond two consecutive sides (40, 40 ', 50, 50') of these two skins (4; 5).

Another feature of the method of the invention consists in that, before drowning the two end portions (130; 140) of a sling (13; 14) of at least one connecting means (11, 12; 11 ', 12') in the concrete of a mold, has such a sling (13, 14) in such a mold that such a sling (13, 14) and / or that the end portions (130, 140) of such sling (13, 14), on the one hand extend parallel or perpendicular to a main direction of extension of the structural reinforcement (9, 10) and, on the other hand, are located at least near a plane (17; ), as described above, perpendicular to the structural reinforcement (9, 10), passing through the center of gravity 16 of the insulating wall 1, and extending parallel or perpendicular to the main direction of extension of the structure reinforcement (9, 10).

Such a feature advantageously makes it possible to produce an insulating wall 1 conforming to the first embodiment mentioned above or, again, in accordance with the second and third embodiments, when at least one side (3; 3 ') of the wall 1 or at least one side (40, 40 '; 50, 50') of at least one skin (4; 5) of the insulating wall 1 comprises a single connection means (11, 11 ', 12, 12 ') as illustrated figure 1 .

In the case of this characteristic, these slings (13, 14) and / or the end portions (130, 140) of these slings (13, 14) are implanted so as to extend at least parallel to such a plane. (17; 18).

Alternatively and according to another characteristic of the method according to the invention, before drowning the two end portions (130; 140) of the slings (13; 14) connecting means (11, 12; 11 ', 12') ) in the concrete of a mold, these slings (13, 14) are arranged in such a mold so that these slings (13, 14) and / or that the end portions (130, 140) of these slings ( 13, 14), on the one hand extend parallel or perpendicular to a main direction of extension of the structural reinforcement (9, 10) and, on the other hand, are implanted on both sides of a plane (17; 18), as described above, perpendicular to the structural reinforcement (9, 10), passing through the center of gravity 16 of the insulating wall 1, and extending parallel or perpendicular to the main direction of extension of the structural reinforcement (9, 10).

Such a characteristic advantageously makes it possible to produce an insulating wall 1 according to the above-mentioned second and third embodiments and when at least one side (3; 3 ') of the insulating wall 1 or when at least one side (40, 40 50, 50 ') of at least one skin (4; 5) of the insulating wall 1 comprise a plurality of connection means (11, 11'; 12, 12 ') as illustrated figures 2 and 3 .

In fact, these slings (13, 14) and / or the end portions (130, 140) of these slings (13, 14) are, again, implanted so as to extend at least parallel to such a plane (17; 18).

According to another characteristic of the method of the invention, before drowning the two end portions (130, 140) of the slings (13, 14) connecting means (11, 12; 11 ', 12') in the concrete of a mold, these slings (13, 14) are arranged in such a mold so that, on the one hand, a sling (13, 14) of at least one connecting means (11, 12) and / or the end portions (130, 140) of such a sling (13, 14) extend parallel to a main direction of extension of the structural reinforcement (9, 10) and, on the other hand, a sling (13, 14) of at least one other connecting means (11 ', 12') and / or the end portions (130, 140) of such a sling (13, 14) extend perpendicular to the main direction of extension of the structural reinforcement (9, 10).

Additionally, these slings (13, 14) are arranged such that these slings (13, 14) and / or that the end portions (130, 140) of these slings (13, 14) are implanted as mentioned. above, namely, at least near a plane (17; 18) as described above, or on both sides of such a plane (17; 18).

Such a characteristic advantageously makes it possible to produce an insulating wall 1, at least two consecutive sides (3; 3 ') of which then have each at least one connecting means (11, 12; 11', 12 '). In fact, these are, more in particular, two consecutive sides (40, 40 ', 50, 50') of the skin or skins (4; 5) of this insulating wall 1 which then and each comprise at least one such connecting means (11, 11 '). 12, 12 ').

It will be observed that another characteristic of the process according to the invention consists in that the process steps carried out in the second mold are carried out after those carried out in the first mold.

An additional feature is that the first mold and the second mold correspond to molds that includes a traditional chain of manufacturing a wall formwork lost.

As mentioned above, there is an insulating panel 8 over the concrete poured into a mold. In fact, this insulating panel 8 may be disposed over the concrete, either at a station for placing such an insulating panel 8 away from the traditional chain of manufacture of a wall (this in at least temporarily removing the first skin 4 of this traditional chain of manufacture of a wall), or (preferably and advantageously) within the traditional chain of manufacture of a wall.

Yet another characteristic of the method of the invention consists in that the structural reinforcement (s) (9; 10) are positioned inside the mold or molds, this within the same traditional chain of manufacture of a wall. .

In addition, this method consists in that the two end portions (130; 140) of the same sling (13; 14) of one and the same connecting means (11, 11 '; 12, 12') are fixed. ) on a frame (9; 10) positioned or to position in the same mold, this within the traditional chain of manufacture of a wall.

This advantageously makes it possible to overcome the drawbacks of the methods of the state of the art which consisted in fixing the two end portions of one and the same sling of the same connection means each on a frame of distinct structure that each contained two skins of the wall. These methods consisted, after having fixed a first end portion of such a sling on a first structural frame of a first skin of the wall, to remove this first skin from the wall out of the traditional production line to bring it to a station at which it was also necessary to bring said second structural armature to fix the second end portion of such a sling, this because of the impossibility of fixing such a second end portion of sling on such a second frame of structure if it was positioned in a mold of the traditional chain of manufacture of wall, in particular because of the positioning, over such a mold and close to it, the first skin equipped with said sling, this when making the second skin of the wall.

Finally, the implementation of this manufacturing method makes it possible to directly obtain the insulating wall with lost formwork 1 having the characteristics described above.
