Description

Title of the invention: wall insulation method

[0001] The present invention relates to the field of wall insulation, in particular for concrete block walls. Prior art

[0002] Wall insulation is currently done by installing insulating panels. These insulating panels are glued or skewered onto the surface of the wall to be insulated. These panels are thus installed on the exterior face of the wall or on the interior face.

[0003] On the interior face of the wall, this installation of panels impacts the living space, whereas on the exterior face, the installation of panels requires the installation of a covering to hide said insulation.

[0004] To avoid this, there is the installation of insulating panels in wooden structures but this type of construction is not common. Indeed, the majority of current constructions are made from concrete blocks which are assembled and joined to form walls.

[0005] A known solution consists of using blocks which are pre-filled with an insulating material, this insulating material being in the form of a foam or a polystyrene-type material. Thus. In the factory, the block is filled with the insulating foam which, when hardening, forms a compact insulating material. In the case of a polystyrene-type material, this is in the form of plates which are slid into the blocks.

[0006] The disadvantage of these blocks is that they do not allow for perfect insulation. Indeed, the blocks need to be joined using mortar. However, the presence of this joint between the blocks makes the insulation non-continuous, which leads to performance losses. In the case of a polystyrene-type material, it can be damaged during its insertion. Summary of the invention

[0007] The present invention seeks to solve the problems of the prior art by providing a method for insulating a building block wall during the construction of said wall.

[0008] In this respect, the invention relates to a masonry structure of the wall type comprising a plurality of building blocks arranged in the form of superimposed lines, each building block comprising at least two parallel wings and at least one through core to form at least one cell intended to be filled with an insulating material, characterized in that the building blocks of said wall are arranged so that, on at least one portion of said wall, the cells of the building blocks of said portion are all communicating in order to form a single cavity, said cavity single being filled with an insulating material in hardened liquid form.

[0009] According to one example, said wall comprises several sections, each section comprising at least one portion of wall in which the cells of the building blocks are communicating to form a single cavity.

[0010] According to one example, said at least one portion of said wall for which the cells of the building blocks of said portion are all communicating in order to form a single cavity

[0011] According to one example, for said at least one portion of wall in which the cells of the building blocks are communicating to form a single cavity, said single cavity comprises a rectilinear portion extending over the entire height of said wall.

[0012] The invention further relates to a method of constructing an insulating wall, said method comprising the following steps: - Equip yourself with building blocks; - Assembling the blocks to form said wall, each building block comprising at least two parallel wings and at least one through core to form at least one cell intended to be filled with an insulating material, said assembly of the building blocks being carried out so that, on at least one portion of said wall, the cells of the building blocks of said portion are all communicating in order to form a single cavity; - Obtain a filling machine designed to dispense insulating material in liquid form; - Fill the single cavity with the insulating material in liquid form; - Allow the said insulating material in liquid form to harden.

[0013] According to one example, for said at least one portion of wall in which the cells of the building blocks are communicating to form a single cavity, said single cavity comprises a rectilinear portion extending over the entire height of said wall, said filling machine then comprising at least one end piece in the form of a rod, the filling step consisting of equipping the rod of the filling machine to slide it into the rectilinear portion of the single cavity, the filling being carried out by injecting the insulating material in liquid form and then raising the rod depending on the filling level.

[0021] - Figures 10 and 12 represent a schematic view of the filling of the wall according to the invention;

[0022] - [Fig.l 1] represents a schematic view of a building block with means of transfer; Detailed description

[0023] In [Fig.l], a wall 1 is shown. A wall according to the invention comprises a plurality of building blocks 10. A wall according to the invention is a wall of a multi-story construction and has a maximum height of 3 to 4m. These building blocks, visible in Figures 2 to 5, each comprise at least two smooth, parallel wings 11 in order to simultaneously produce the two opposite faces of a wall, these two wings are connected to each other by at least one through core 12. This through core can be rectilinear or have a more complex shape. Each building block can thus comprise one, two, three or more cores. These cores can be distributed regularly or not. A block with at least two cores then has at least two spaces or cells 13, these spaces being delimited by three or four vertical walls. The cores can extend over at least 50% of the height of the block up to the entire height of the block.

[0024] A first example of building block 10 comprises two parallel wings and three parallel cores making it possible to define three spaces or cells 13.

[0025] A second example of a block comprises two parallel wings connected by two parallel cores arranged at the ends. The block further comprises a square-shaped island cavity connected to the two wings, or even to the two cores.

[0026] In one embodiment, the wall comprises a plurality of blocks identical to each other.

[0027] In another embodiment, the wall comprises a plurality of building blocks 10, these being divided into at least two series of different blocks.

[0028] In its construction, the wall is presented in the form of a superposition of lines of building blocks. Between two lines directly overlapping, the building blocks are offset from each other.

[0029] According to the invention, the wall is constructed in such a way, in at least one portion of said wall, the building blocks are arranged so as to form only one cavity. This means that the building blocks 10 all communicate with each other, in particular at the level of at least one cell, so that the blocks form a continuous space.

[0030] This arrangement of the building blocks allowing for a continuous space makes it possible to fill this single space. More particularly, this space is filled using an insulating material which is poured and hardens. More precisely, the insulating material is a mineral foam. This mineral foam is then injected into the single space of this portion of wall in order to fill it with said foam.

[0031] This configuration of the wall requires that the assembly of the building blocks is carried out in advance so that the joint (mortar) used does not obstruct the cells of the building blocks.

[0032] In a first non-limiting example of construction visible in [Fig.6], each building block comprises two wings connected to each other by three cores in order to form a two-cell building block. The construction of the wall then consists of having an offset between two lines equal to half a block. This offset makes it possible to have each cell 13 of the building block 10 opposite a cell of a block located on the upper line and a cell of a block located on a lower line.

[0033] In a second construction example, the building block 10 comprises two wings connected together by three cores in order to form a two-cell building block 13. The construction of the wall is such that the offset between the blocks of two lines is equal to at least a quarter of a block as visible in [Fig.7]. This offset allows each cell to communicate with two cells of the upper line and two cells of the lower line. This second example makes it possible to fill twice as many cells.

[0034] In a third construction example, the building block comprises two wings connected together by four cores to form a three-cell building block. The construction of the wall is such that the offset between the blocks of two lines is equal to at least one third of a block as seen in [Fig.9]. This offset allows each cell to communicate with two cells of the upper line and two cells of the lower line.

[0035] Of course, other construction examples are possible depending on the configuration of the blocks.

[0036] In a variant, the wall is divided into sections, each section comprising at least one portion of wall whose building blocks are arranged so as to form only one cavity. It is then understood that each section can comprise several portions, at least one of which is arranged so that its building blocks are arranged so as to form only one cavity. Preferably, each portion of the section is arranged so that its building blocks are arranged to allow for only one cavity.

[0037] In another variant, the entire wall is arranged so that the building blocks form only one cavity. This variant is advantageous in that it allows for a wall without breaking the insulation.

[0038] Preferably, in said portion of said wall, the building blocks are arranged so as to form only one cavity, this cavity being such that from the top of the wall, it is possible to see the bottom as visible in [Fig.9]. In other words, the single cavity of the wall portion is such that it forms a light from top to bottom, that is to say that a rectilinear axis can be inserted therein. This preference in the arrangement of the building blocks allows the insulating material to be injected in a clever manner.

[0039] Indeed, depending on the nature of the insulating material in liquid form which is injected into said single cavity, it is not necessarily advisable to pour it from a significant height. This injection from a great height can result in degrading the liquid material and thus causing it to lose its capacities during its hardening. In particular, in the case of an insulating material in the form of a mineral foam in liquid form, falling from too great a height can cause the foam to break. A liquid foam consists of an abundance of gas bubbles separated by a liquid which, itself, forms a continuous phase. Thus, the stress exerted by the fall can break the bubbles so that the trapped gas escapes. The foam then becomes a liquid which then reacts differently.

[0040] Now, with a single cavity arranged to form a light from top to bottom, it is then possible to insert a filling machine 20 therein. This filling tool can be lowered to the desired height to fill said single cavity without degrading the insulating material in liquid form.

[0041] The filling of the single cavity is then done by means of a filling rod 24. This filling rod consists of a rigid or flexible rod connected to a reservoir 21 associated with a pump 22. The filling rod 24 is connected to the pump-reservoir assembly by a pipe 23. This filling machine 20 makes it possible to inject the insulating material.

[0042] This rod is then, beforehand, lowered along the lumen of the single cavity to a defined height. This height is defined according to the specificity of the insulating material to be injected. The rod can then be lowered to a height of a few millimeters from the ground to, for example, halfway up the wall.

[0043] The insulating material in liquid form is then injected via the rod. Said rod is then lifted as the single cavity is filled.

[0044] For filling an entire wall, at least one filler rod is required. wise. The number of rods depends on the number of unique cavities and the width of the wall and the configuration of the wall.

[0045] Indeed, in the case of a wall comprising several sections, each section can be filled independently.

[0046] In the case of using several rods, these can be independent, that is to say each connected to a pumping machine. But it is possible that they are all connected to the same machine as visible in [Fig.12].

[0047] In one variant, the building blocks are designed to have at least two cells: one cell intended to be filled with the insulating material and one cell intended to be filled with air. This configuration makes it possible to have two “insulating layers” in the block: an insulating blade and an air blade. These two cells can have different shapes and be arranged differently in the building block. In one example, the two cells are identical and extend parallel along the length of the building block 10.

[0048] In another variant visible in [Fig. 11], the building blocks are designed to have at least two cells arranged to be filled with an insulating material. These two cells are communicating. This means that the two cells are connected by a transfer means 14 such as a groove or an opening allowing the insulating material filling one of the cells to fill the second. The presence of this communication between the cells facilitates their filling.

[0049] Of course, the present invention is not limited to the illustrated example but is susceptible to various variants and modifications which will appear to those skilled in the art.
