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.

Such a formwork wall comprising the features of the preamble of claim 1 is known from 2-927-105-EN . 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.

This process is characterized by the fact that:

• the connection means or means are engaged through an insulating panel, either before disposing this insulating panel over the concrete poured into the first mold and before disposing this connection means or means in this first mold, or after having disposed this insulating panel over the concrete poured into the second mold and before introducing this or these connecting means into the concrete poured into the second mold;

The presence of such a connecting means and its arrangement within the wall (flooding of the first two end portions of two slings each in a skin separate from the wall and securing of the two second end portions of these two slings) advantageously make it easier to manufacture such a wall.

The invention also relates to a method of manufacturing a lost-form insulating wall, this process consisting of drowning, on the one hand, in the concrete poured into a first mold and during a first step of manufacturing the wall. , a first end portion of a first sling of a connecting means and, secondly, in the concrete cast in a second mold and in a second step of manufacturing the wall, a first portion of end of a second sling. These two steps are easy to implement, routine for a person skilled in the art, and likely to be performed within the same production line. This method consists, again and during a third step, to secure the second end portions of the two slings of the same connection means. In fact, this solidarity can, advantageously, intervene at any time from the overturning of the first skin and the introduction of the connection means that this first skin has in the concrete of the second skin, especially while the second skin is being dried, or even after removal of the insulating wall of the production line, in particular before or during its storage. This joining can also, and advantageously, intervene on the production line or outside this production line, especially after the manufacturing process and after having permanently removed the wall of this production line for storage.

Advantageously, it is also possible to set up such a connecting means (in particular the slings) as well as the structural reinforcements on which such connecting means is fixed, this within the same chain of traditional manufacturing (which is already fed at least structural reinforcement) and without having, as in the state of the art, to route, store, and put in place, such a structural reinforcement at the level of a remote station for setting up an insulating panel.

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.

The present invention relates to the field of the building and, more particularly, that of the manufacture, at the factory, the insulating walls with lost formwork.

For the sake of simplicity, such an insulated wall formwork lost will be called insulating wall in the following description.

Thus, in known manner, such an insulating wall 1 comprises, then, firstly, two parallel plane faces 2 oriented towards the outside of the wall 1 and, secondly, a plurality of sides (3; 3 '; 3 ") which succeed one another around the periphery of such a wall 1, so that such a wall 1 has consecutive sides (3, 3', 3; 3"). In fact, such a wall 1 comprises, then and in particular, a first side 3 (corresponding to the upper side 3 of the insulating wall 1) and a second side 3 '(corresponding to a lateral side 3' of this insulating wall 1 ) succeeding such a first side 3, in particular perpendicular to this first side 3. According to a preferred embodiment illustrated in the appended figures, such a wall 1 adopts the shape of a parallelepiped, more particularly a rectangular parallelepiped.

Such an insulating wall 1 comprises a first skin 4 and a second skin 5, these two skins (4; 5), being made of concrete or the like, arranged in a parallel manner and spaced apart, so as to define between them (4; ) an internal volume 6 to the insulating wall 1.

Such an insulating wall 1 also comprises at least one first reinforcement of structure 7 at least partially embedded inside the first skin 4 and at least one second reinforcement of structure 8 at least partially embedded in the inside the second skin 5.

In this connection, it will be observed that such a structural reinforcement (7; 8) can take the form of a lattice integrally embedded within such a skin (4; 5). The insulating wall 1 can then have such a frame of structure 7 embedded inside the first skin 4 of the insulating wall 1 and / or such a frame of structure 8 embedded inside the second skin 5 of this insulating wall 1.

Such a frame of structure 8 may also adopt the shape of a basket or the like. The insulating wall 1 may then have at least one such structural reinforcement 8 at least partially embedded inside one of the two skins 5 of the insulating wall 1, more particularly the second skin 5 intended to be oriented towards inside the building.

A particular embodiment of the invention consists in that the insulating wall 1 comprises a frame of structure 7 adopting the form of a lattice and embedded inside the first skin 4 of the insulating wall 1 and at least a frame of structure 8 adopting the shape of a basket at least partially embedded inside the second skin 5 of this insulating wall 1.

It will be observed that such a structural reinforcement (7; 8) extends in a principal direction of extension corresponding to a substantially vertical direction, this when the insulating wall 1 adopts a raised, storage or service position (in which this insulating wall 1 is installed on site for the realization of a building).

In this regard, it will be observed that, when a structural reinforcement (7; 8) is constituted by a beam or a basket, such a beam or such a basket then extend in such a main direction of extension. However, and when such a structural reinforcement (7; 8) is constituted by a lattice, part of the bars forming part of such a lattice then extends in such a main extension direction while another part of these bars extends in a direction perpendicular to this main extension direction.

The insulating wall 1 also comprises at least one connecting means 9 for connecting the two skins (4; 5) of the wall 1 to one another. Such a connection means 9 usually adopts the form of a connector or the like.

This insulating wall 1 also comprises at least one insulating panel 10, made of an insulating material (in particular polyurethane, rock wool or the like), positioned inside the internal volume 6 of the wall 1, and extending parallel to the two skins (4, 5) of the wall 1, more particularly near the skin 4 intended to be oriented towards the outside of the building.

Another characteristic is that the insulating wall 1 comprises at least one connection means (11, 11 ', 12, 12') for connecting this insulating wall 1 to a handling machine.

Such a connecting means (11, 11 '; 12, 12') comprises, on the one hand, a first inner part (110; 120) embedded inside the first skin 4, on the other hand, a second an inner portion (111; 121) embedded within the second skin 5 and, on the other hand, an outer portion (112; 122) interposed between the two inner portions (110,111; 120,121), in the extension of which (112; 122) are these two internal parts (110, 111; 120, 121), and shaped to cooperate with a handling machine.

The insulating wall 1 also comprises at least a first fastening means 13 for fixing the first internal part (110; 120) of such a connecting means (11, 11 '; 12, 12') on the first frame of structure 7 of the first skin 4 and at least one second fastening means 14 for fixing the second inner portion (111; 121) of such a connecting means (11, 11 '; 12, 12') on the second structure frame 8 of the second skin 5.

Also according to the invention, the first inner part (110; 120) of such a connecting means (11, 11 '; 12, 12') is formed by a first end portion 150 that includes the first sling 15 while the second inner portion (111; 121) of such a connecting means (11, 11 '; 12, 12') is constituted by a first end portion 160 that includes this second sling 16.

With regard to the external part (112; 122) of such a connection means (11, 11 '; 12, 12'), the latter (112; 122) comprises, on the one hand, a second portion of end 151 which comprises the first sling 15, on the other hand, a second end portion 161 that includes the second sling 16 and, secondly, at least one securing means 17 to firmly secure the second portion of end 151 of the first sling 15 and the second end portion 161 of the second sling 16.

Another feature of the invention is that the one or more securing means 17 comprise at least one crimping means for crimping between them the second end portions (151; 161) of the first sling 15 and the second sling. 16.

Such crimping means may be constituted by a crimped ring or the like.

However, according to another embodiment, the one or more fastening means 17 comprise at least one cable clamp for clamping between them the second end portions (151; 161) of the first sling 15 and the second sling 16.

Yet another characteristic of the invention consists in that the first end portion 150 of the first sling 15 or the connecting means (11, 11 '; 12, 12') is located opposite the the first end portion 160 of the second sling 16 of this or these connection means (11, 11 '; 12, 12').

Such an embodiment then makes it possible, advantageously, for the second end portion 151 of the first sling 15 of the connection means (11, 11 '; 12, 12') to be implanted opposite the the second end portion 161 of the second sling 16 of this or these connecting means (11, 11 '; 12, 12') which advantageously makes it possible to facilitate the securing of the second end portions (151; 161) of these two slings (15 16).

This also makes it possible for the first internal part (110; 120) of the connection means (11, 11 '; 12, 12') to be implanted opposite the second internal part (111; 121). this or these connection means (11, 11 '; 12, 12').

It will be observed that the insulating wall 1 has a center of gravity 18 with respect to which it is possible to define, on the one hand, a first plane 19 passing through this center of gravity 18 of this insulating wall 1, and perpendicular to the insulating wall. 1 and / or to the structural reinforcement (7, 8). This first plane 19 extends parallel to the main direction of extension of the structural reinforcement (7, 8), ie substantially vertically when the insulating wall 1 adopts a raised position, storage or service.

On the other hand, it is also possible to define a second plane 20, passing through this center of gravity 18 of this insulating wall 1, and perpendicular to the insulating wall 1 and / or to the structural reinforcement (7, 8 ). This second plane 20 then extends perpendicular to the main direction of extension of the structural reinforcement (7, 8), ie substantially horizontally when the insulating wall 1 adopts a raised position, storage or on duty.

Also and according to another characteristic of the invention, at least one connection means (11, 11 '; 12, 12') and / or the sling (15, 16) of at least one connecting means (11, 12 11 ', 12') and / or the first end portions (150, 160) of the slings (15, 16) of at least one connecting means (11, 11 ', 12, 12') extend parallel or perpendicular to the main direction of extension of the structural reinforcement (7, 8).

This being and according to an additional feature of the invention, the connection means (11; 12) and / or the slings (15, 16) of the connection means (11; 12) and / or the first end portions (150, 160) of the slings (15, 16) of the connection means (11; 12), on the one hand, extend parallel or perpendicular to a main direction of extension of the structural reinforcement (7, 8) and, on the other hand, are located at least near a plane (19; 20), as described above, perpendicular to the insulating wall (1) and or at the structural reinforcement (7, 8), passing through the center of gravity (18) of this insulating wall (1), and extending parallel or perpendicular to a main direction of extension of the reinforcement of structure (7, 8).

According to a particular variant embodiment, such a plane (19; 20) is situated midway between the lateral ends of one side (3; 3 ') of the insulating wall 1 and / or halfway on two opposite sides. (3 ', 3 ") of this insulating wall 1.

As an example of this additional feature, it has been illustrated figure 1 , an insulating wall 1 comprising a single first sling 15 and a single second sling 16, so that this insulating wall 1 comprises a single connection means 11. In this case, the connecting means 11 and / or the slings (15 , 16) of this connecting means 11 and / or the first end portions (150, 160) of the slings (15, 16) of this connecting means 11 are implanted as described above, namely, of on the one hand, so as to extend parallel to a main direction of extension of the structural reinforcement (7, 8) and, on the other hand, at least in the vicinity of a plane 19, perpendicular to the insulating wall ( 1) and / or to the structural reinforcement (7, 8), passing through the center of gravity (18) of this insulating wall (1), and extending parallel to a main direction of extension of the reinforcement of structure (7, 8).

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 the first skin of the wall out of the traditional manufacturing 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 sling on such a second structural reinforcement 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, of the first skin equipped with said sling, this during the realization of 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.
