Description

Title: Double-frame concrete structure

Technical area

[0001] The invention relates to the field of construction of buildings or structures, in particular buildings intended for regions subject to extreme natural risks. The invention also relates to the field of manufacturing processes for such buildings.

Prior art

[0002] The construction of buildings in areas subject to extreme natural risks such as earthquakes, cyclones or even heatwaves must respect safety standards specific to the country to which this region belongs and sometimes additional standards specific to the region. area. Generally, buildings must have resistance to winds and earth movements, and sufficient insulation.

[0003] To create such buildings, traditional construction, in cement brick or terracotta with concrete beams, is costly in time and money, especially in isolated regions. Construction by juxtaposition of prefabricated unitary concrete panels offers the advantage of a speed of elevation in floors but requires significant resources, in particular lifting means. In addition, additional means of insulation must be provided for this type of construction.

[0004] We also know the construction by interlocking bricks filled with extruded insulation to form walls. However, the precarious anchoring of the construction to the ground is a major problem with this type of construction. We know the construction consisting of screwing edge boards onto a slab and which will serve as a rail to fit together a double panel comprising extruded insulation. The structure obtained does not present the necessary criteria to meet anti-cyclonic requirements and it is not possible to reinforce the structure with bracing buttresses. In addition, the insulation in its structures remains to be improved.

[0005] We also know the construction by juxtaposition facing each other of quick cement panels to form a wall and on which polystyrene plates are glued. Polystyrene sheets are narrower than quick cement panels so as to create a space for pouring concrete. This solution does not solve the differential pressure problem that can be encountered in cyclonic areas. This solution does not apply to wooden construction. Given that prompt cement cannot be cut, this solution requires construction in multiples of the width of a unit panel. This also implies that all accessories allowing the creation of windows, doors, lintels and frames must be prefabricated. In addition, the pressure due to the filling of the concrete at the base of the panels is not contained and therefore requires significant shoring of each panel and progressive pouring of the concrete. The facing panels being held together by the poured concrete, the entire wall absorbs the stresses and the same deformation will be observed on both sides of the wall. In addition, there is no insulation between the cement panels and the concrete posts, which creates a significant thermal bridge. The insulation of the structure obtained remains to be improved.

[0006] The invention aims to remedy these drawbacks.

Summary [0007] For this purpose, the invention proposes a structure comprising a wall extending in a vertical direction and a horizontal direction, and having a thickness in a transverse direction, said wall being formed by a row of first panels and a row second panels arranged opposite the first panels, the structure further comprising a row of first hollow posts extending vertically and a row of second hollow posts extending vertically, the row of first hollow posts being opposite the row of second hollow posts, each of the first panels, respectively second panels, being fixed to two successive first hollow posts, respectively to two successive second hollow posts, and in which each of the first panels and the second panels comprises a first layer, and in which said first hollow posts and second hollow posts are arranged between the first layer of the first panels and the first layer of the second panels, and in which the first hollow posts being spaced from the second hollow posts in the transverse direction by at least a distance equal to the width of the hollow posts.

[0008] Thus, a first frame is formed by the first posts and a second concrete frame is formed by the second posts. This double framework makes it possible to improve the resistance of the structure, in particular to earthquakes and cyclones to which the structure may be exposed, in particular when concrete is poured into said posts.

[0009] For example, the first frame with the first panels form an exterior face of the structure and the second frame with the second panels form an interior face of the structure which defines the internal space of the structure.

Said first layer can be a layer of wood, in particular a plate of thin, long and oriented strips (or OSB for “oriented strand board” in English). The first layer can be a layer of fiber cement, glass fibers, carbon fibers, cardboard or polymers, for example plastic. Said first layer may be a layer of light cement fiber sheets.

[0011] According to one embodiment, the first hollow posts and the second hollow posts can be arranged staggered in the horizontal direction. For example, each first hollow post can be arranged substantially at the midpoint of the segment between two of the second hollow posts opposite said first post. Said second hollow posts and said first hollow post thus arranged make it possible to ensure tripod transverse stability and to improve the maintenance of the structure.

[0012] The hollow posts can be tubes made of plastic, in particular polyvinyl chloride.

[0013] According to one embodiment, each of the first panels and the second panels may comprise a first insulating element carried by the first layer.

The first insulating element may have dimensions equal to those of the first layer.

The first insulating element may be a layer of a first insulating material, for example a polymer, in particular extruded polystyrene. The first insulating element may have a thickness of between 10 mm and 30 mm, in particular around 20 mm. The first insulating element can be fixed to the first layer by any suitable fixing means, for example by screwing or gluing.

[0016] According to one embodiment, each of the first panels and the second panels may comprise at least one second insulating element carried by the first insulating element. The second insulating element may include an insulating material having a density lower than the density of an insulating material of the first insulating element.

Advantageously, said at least one second insulating element may have a dimension in the horizontal direction equal to or slightly greater than the distance between two hollow posts.

Said at least one second insulating element may have a dimension in the horizontal direction equal to or less than the distance between two hollow posts.

The second insulating element may be a layer of a second insulating material having a density lower than that of the first insulating material. The second insulating material may be a polymer, in particular expanded polystyrene. The second insulating element may have a width less than the width of the first layer and a length greater than the length of the first layer, in particular from 5 cm to 15 cm. This allows you to leave an empty space at the level of the plinths, or the foot, of the wall in order to allow wiring or piping to pass through. The second insulating element may have a thickness of between 50 mm and 150 mm, in particular approximately 100 mm. The width of the second insulating element can be between 30 cm and 70 cm, in particular equal to 50 cm. The second insulating element can be fixed to the first insulating element by any suitable fixing means, for example by screwing or gluing. The second insulating element may have a thickness or a dimension in the transverse direction substantially equal to the dimension in the transverse direction of the hollow posts.

[0020] The width of the first and/or second panels can be between 40 cm and 80 cm, in particular equal to 60 cm and the length of the first and/or second panels 100 can be between 200 cm and 310 cm , in particular equal to 240 cm. The first and second panels can have identical dimensions and thus form unit modules for modular construction.

[0021] The wall of the structure may further comprise first chaining panels and second chaining panels arranged below several first panels, respectively second successive panels. The chaining panels can extend horizontally over the first/second panels.

[0022] Each chaining panel may comprise the first layer, the first insulating element and a plurality of second insulating elements carried by the first insulating element. Each of the second insulating elements may be formed by the second insulating material, such as expanded polystyrene.

[0023] Each chaining panel can successively comprise the first layer, the first insulating element and a plurality of second insulating elements. The distance in the horizontal direction between two insulating elements may be equal to or slightly greater than the width in the horizontal direction of one of said hollow posts.

The first and second panels and the chaining panels can be assembled to the hollow posts by any suitable means such as by screwing. [0025] The hollow posts may comprise concrete. By concrete we mean any type of agglomerate, for example concrete can include a mixture of aggregates and a binder. The aggregates may include a mixture of sand and/or gravel and/or chippings, etc. The binder can be cement or clay or resin or bitumen.

The first hollow posts or the second hollow posts may comprise reinforcing wires passing through said hollow posts.

[0027] In particular, the second hollow posts forming part of the internal face of the structure may comprise reinforcing wires cast in concrete while the first hollow posts forming part of the external face may comprise only concrete, in particular fiber-reinforced concrete. Thus, the external face of the walls is ductile and can deform when the structure is subjected to significant external forces due to a cyclone or an earthquake while the internal face of the walls is rigid and does not deform as the external face absorbs these strengths.

[0028] Each hollow post can be mounted on a base fixed to a slab designed to receive said structure.

According to one embodiment, one of the panels may have a first edge cooperating with a second edge of a panel adjacent to said panel. In particular, the first edge can be a male rebate and the second edge a complementary female rebate.

According to one embodiment, one or more additional insulating elements, such as expanded polystyrene, can be arranged between the first panels and the second panels. In addition, an empty space can be provided between said additional insulating elements and the first and/or second panels so as to form a non-convective inert air chamber to improve insulation.

[0031] The structure may comprise at least one hollow reinforcing post extending in an inclined manner from one of the first hollow posts, arranged at the end of the wall, to another first hollow post adjacent to said end post. Thus, concrete, reinforced or not with steel wires, can be poured into said reinforcing post.

[0032] According to one embodiment, the first panels forming the external face of the structure may comprise fixing means capable of supporting cladding or exterior facing elements of the structure. The fixing means can be arranged between the first panels and screwed to the first hollow posts and embedded in the concrete, allowing better fixing of the cladding.

[0033] According to another embodiment, the first panels forming the external face of the structure may comprise a hanging fabric, covering said first panels, and capable of receiving cladding or exterior facing elements of the structure. Said hanging fabric can be made of glass fabric and glued to said first panels.

[0034] The structure can be intended for different uses, such as: for agricultural use and can be any type of warehouse, barns or garages, for housing and can be any type of single-storey and/or two-storey individual houses, or residential buildings, for commercial use and can be any type of stores or offices, for industrial use and can be any type of factories or even workshops, or for administrative use and can be any type of police stations, town halls, prefectures, multipurpose rooms, performance halls, schools or hospitals. According to one embodiment, the assembly of a first panel and a second panel can form a wall part. The structure may comprise at least one positioning shoe of said wall part having the same dimensions as those of a lower end of said wall part. Each positioning shoe can be fixed to the slab intended to receive said structure. Each positioning shoe may include a housing for receiving one end of a first or second post.

Each positioning shoe can be a polymer plate, for example extruded polystyrene. Each positioning shoe can have a thickness of approximately 30 mm. Thus, the positioning shoes make it possible to align the wall parts and thus facilitate the assembly of the wall. In addition, the positioning shoes make it possible to improve the sealing at the level of the slab and to eliminate the thermal bridge between the slab and the wall.

The assembly of said wall portion may comprise the first panel and the second panel sandwiching a common insulator. Said common insulator may comprise one or more housings designed to each accommodate a first post or a second post. Said common insulator may include a half-housing footprint such that when two common insulators are arranged side by side, said half-housing footprints may form an entire housing to receive a first post or a second post. For example, each common insulator may include a housing for receiving a first post, arranged on an external side of the wall or external face of the structure, and two half-housing footprints, arranged on an internal side of the wall or internal face of the structure. For example, the first panel and the second panel can be mounted by gluing on the common insulation. Each common insulator may comprise at least one recess forming a housing provided for the passage of electrical cables or piping of said structure.

According to one embodiment, each positioning shoe may comprise at least one notch designed to receive a connector configured to connect two positioning shoes together. Said connector may have a bone shape. Said connector may be made of polymer, for example extruded polystyrene, and may have a thickness of approximately 30 mm.

[0040] Each positioning shoe can be glued to the slab, in particular a concrete slab, intended to receive the structure. In particular, the positioning shoes can be glued to said slab after positioning all the positioning shoes forming the perimeter of the structure.

[0041] The structure may include a cover configured to be arranged above a part of the wall and having a shape similar to that of the positioning shoe corresponding to the part of the wall. Each cover may be made of polymer, for example extruded polystyrene, and may have a thickness of approximately 20 mm. Each cover may have a section similar to that of the positioning shoe. In addition, connectors can be provided to connect the covers together.

The structure may include a corner formed at the intersection of a first wall and a second wall, perpendicular to each other. The rows of first posts of the first wall and the second wall may include an end post arranged at the corner common to the first wall and the second wall. The row of second posts of the first wall may include a first end post at the corner and the row of second posts of the second wall may include a first end post at the corner. The row of first posts can be arranged on the side of the external face of the structure and the row of second posts can be arranged on the side of the internal face of the structure.

[0043] According to another aspect of the invention, a first method of constructing a structure such as the aforementioned is proposed, comprising the steps consisting of: assembling each first panel and each second post so as to form a part of a wall, arrange the assembly each first panel and each second post on a slab designed to accommodate said structure, install the row of first hollow posts and the row of second hollow posts in a staggered pattern by sliding said first and second posts into housings provided for this purpose between each first panel and each second post, pour concrete into the first and second hollow posts.

[0044] The first method may comprise, prior to the preceding steps, the steps consisting of: placing the positioning shoes on the slab so as to form the periphery of the structure, gluing the positioning shoes on said slab, pulling wires from reinforcement from said slab through the post housings provided in the positioning shoes.

[0045] The first method may include the arrangement of the covers after the installation of the row of first hollow posts and the row of second hollow posts, and in particular before pouring the concrete into the first and second hollow posts.

[0046] According to another aspect of the invention, a second method of constructing a structure as mentioned above is proposed, comprising the steps consisting of: arranging the row of first hollow posts so as to define a first framework of the structure , fix each first panel to two successive first hollow posts, arrange the row of second hollow posts in a staggered manner so as to define a second framework of the structure, fix each second panel to two successive second hollow posts, install crossing reinforcement wires into the first hollow posts or the second hollow posts, and pouring concrete into the first and second hollow posts.

detailed description

[0065] In the figures, the same references designate identical or similar elements.

[0066] With reference to Figures 1 to 6, the structure according to the invention comprises at least one wall 200 having a first face formed by a plurality of first panels 100-1, extending in a vertical direction z and juxtaposed in a horizontal direction x and a plurality of second panels 100-2 extending in a vertical direction z and juxtaposed in the horizontal direction x. The first panels 100-1 and the second panels 100-2 are arranged facing each other and at a distance following the thickness of the wall 200, or in a transverse direction y.

[0067] Each of the first and second panels 100 comprises the following successive layers: a wooden layer 102, a first insulating element 104 and a second insulating element 106. The wooden layer 102 may have a thickness of between 10 mm and 30 mm , in particular between 15 mm and 22 mm, and can be made of any type of agglomerated wood and in particular a plate of thin, long and oriented strips (or OSB for “oriented strand board” in English). The first insulating element 104 is a layer of a first insulating material, for example a polymer, in particular extruded polystyrene. The first insulating element 104 has the same width L2 and length L1 as the wooden layer 102. The first insulating element 104 can have a thickness between 10 mm and 30 mm, in particular approximately 20 mm. The first insulating element 104 can be fixed to the wooden layer 102 by any suitable fixing means, for example by screwing or gluing. The second insulating element 106 is a layer of a second insulating material having a lower density than that of the first insulating material. The second insulating material may be a polymer, in particular expanded polystyrene. The second insulating element 106 has a width L4 less than the width L2 of the wooden layer 102 and a length L5 greater than the length L2 of the wooden layer 102, in particular from 5 cm to 15 cm. This makes it possible to leave an empty space at the level of the plinths, or the foot, of the wall 200 in order to pass wiring or piping. The second insulating element 106 may have a thickness of between 50 mm and 150 mm, in particular approximately 100 mm. The width L4 of the second insulating element 106 can be between 30 cm and 70 cm, in particular equal to 50 cm. The second insulating element 106 can be fixed to the first insulating element 104 by any suitable fixing means, for example by screwing or gluing.

[0068] The width L2 of the panels 100 is between 40 cm and 80 cm, in particular equal to 60 cm and the length L1 of the panels 100 is between 200 cm and 310 cm, in particular equal to 240 cm. The first and second panels have identical dimensions and thus form unit modules for modular construction.

[0069] According to one embodiment, the wooden layer 102 of each of the first and second panels 100 can be replaced by a layer of fiber cement, glass fibers, carbon fibers, cardboard or polymers, for example plastic.

[0070] The wall 200 further comprises first chaining panels 120-1 and second chaining panels 120-2 arranged below several first panels 100-1, respectively second panels 100-2, successive. The chaining panels 120 extend horizontally over the panels 100.

[0071] Each chaining panel 120 comprises the same elements as the panel 100. With the difference, each chaining panel 120 comprises a plurality of second insulating elements 126 carried by the first insulating element 104. Each of the second insulating elements 126 is formed by the second insulating material, such as expanded polystyrene. Each of the second insulating elements 126 has a width L4 and a length L3.

[0072] As can be seen in Figure 2, the side edges of two adjacent wooden layers 102 are provided with coupling means. In particular, the left panel 102 comprises a male rebate 108 configured to fit with a female rebate 110 of the left panel 102. The male 108 and female rabbets 110 are arranged on the vertical side edges of the panels 102. In addition, the upper edge of the panel 100 and the lower edge of the chaining panel 120, designed to fit with said upper edge of the panel 100 , comprise coupling means, such as male rebates 112 at the upper edge of the panel 100 and female rebates at the lower edge of the chaining panel 120. This assembly method makes it possible to simplify the production of the structure.

[0073] The wall 200 also includes first hollow posts 202-1 and second hollow posts 202-2 aligned horizontally. The first hollow posts 202-1 are distributed in a first row and the second hollow posts 202-1 are distributed in a second row, arranged opposite the first row of first hollow posts. The first hollow posts 202-1 and the second hollow posts 202-2 are received from the bases 212-1 and 212-2, which are fixed on a slab 216, visible in Figure 6, and intended to support the structure. The row of first hollow posts 202-1 is spaced, in the transverse direction y, from the row of second hollow posts 202-2, by at least the thickness of a hollow post. As is better visible in Figure 5, the first hollow posts 202-1 and the second hollow posts 202-2 are arranged in a staggered manner. For example, each first hollow post 202-1 is arranged substantially at the midpoint of the segment between two second hollow posts 202-2 opposite said first hollow post 202-1. Said second hollow posts and said first hollow post thus arranged ensure tripod transverse stability and improve the maintenance of the structure.

[0074] The first panels 202-1 and the first chaining panel 120-1 are screwed to the first hollow posts 202-1 by screws 21 1. Likewise, the second panels 202-2 and the second chaining panel 120-2 are screwed to the second hollow posts 202-2 by screws 211.

[0075] With reference to Figures 6 and 7, vertical reinforcing wires 213 are arranged in the first hollow posts 202-1. Other reinforcing wires 214 are arranged above the panels 100 and are configured to reinforce a concrete slab 220 intended to form a one-story floor above the wall for example. In addition, horizontal reinforcing wires 218 are cast in the concrete forming the slab 216. The reinforcing wires can be steel wires.

Advantageously, concrete is also poured into the hollow posts 212-1 and 212-2. As can be seen in Figure 4, the screws 21 1 are embedded in the concrete. In addition, the hollow posts have walls 202-a which are here in the horizontal direction x, having a thickness greater than the thickness of the walls 202-b of the hollow posts, perpendicular to the walls 202-a. Thus, the walls 202-b can deform under the pressure of the concrete according to the directions F1 and F2 and compress the second insulating elements 106, which improves the maintenance of the panels 100 and 120. The hollow posts 202-1, 202-2 are made of plastic, in particular polyvinyl chloride.

[0077] The panels allow the hollow posts to be held in position before pouring the concrete.

[0078] Figure 7 only shows the concrete structure obtained after pouring concrete into the hollow posts in the absence of panels 100, 120 and 130. Thus, a first concrete frame is formed by the first hollow posts 202-1 and a second concrete frame is formed by the second hollow posts 202-2. For example, the first frame with the first panels 100-1 form an exterior face of the structure and the second framework with the second panels 100-2 form an interior face of the structure which defines the internal space of the structure. The double concrete frame improves the resistance of the structure, particularly to earthquakes and cyclones to which the structure may be exposed. Indeed, the principle of the double staggered concrete frame allows the first external frame in more ductile unreinforced fiber-reinforced concrete to absorb the pressure stresses generated by a cyclone while the second internal frame in more rigid, reinforced fiber-reinforced concrete, because it is reinforced, receives almost no deformation.

[0079] Openings can be provided in the walls forming the structure, such as doors 224 or windows 231.

[0080] The width L2 of the panels 100-1 and 100-2 is chosen so as to cover the hollow posts 202-1 and 202-2. [0081] The length L3 of the second insulating elements 126 of the panels 120 is chosen so that the distance between two second insulating elements 126 corresponds to the width of the hollow posts 202-1, 202-2.

[0082] To improve the insulation of the wall, one or more additional insulating elements can be arranged between the first panels 100-1 and the second panels 100-2. Figure 8 shows several examples of possible insulation. For example, in Figure 8a, no additional insulation element is inserted between the panels and the insulation is only provided by the insulating elements 104 and 106 of the panels 100. In Figure 8b, a layer 210 of a insulating material, such as expanded polystyrene, is arranged between the second insulating elements 106 of the panels 100-1 and 100-2. In Figure 8c, an empty space is provided between the second insulating elements 106 of the panels 100-1 and 100-2. This empty space is filled only at the foot of the panels by a strip 212 of insulating material and at the head of the panels by a strip 208 of insulating material. In this case, insulation is provided by a chamber of inert, non-convective air. Following this principle, several chambers of inert non-convective air can be compartmentalized between panels 100-1 and 100-2. For this, strips 212 and 208 are alternated with one or more layers 210 of insulating material, forming two air chambers as shown in Figure 8d or three air chambers as shown in Figure 8e. The construction principle makes it possible to adapt the insulation according to the climate thanks to the creation of an unlimited quantity of inert non-convective air chambers between the two frames using the same quantity of hollow posts and panels. In other words, the cost of creating the structure is almost identical regardless of the thermal constraints of the region considered. For example, we can consider insulating a wall exposed to the cold more effectively than other less exposed walls from the same panels and the same hollow posts.

[0083] In addition, the length L1 of the first panels 100-1 is chosen so as to cover the floor slab 220.

[0084] The panels 100, 120 and 130 are made from materials that are easy to machine, which further simplifies the production of the structure.

[0085] Figure 9 represents a wall 300 with an opening 231 provided for a window. The hollow posts 202-1 and 202-2 around the opening 231 have dimensions adapted to the spandrel of the window envisaged. In addition, horizontal hollow posts 221 are arranged to frame the window and form upper and lower supports of the window. The horizontal hollow posts 221 include hatches 228 allowing the passage of reinforcing or ligature wires and hatches 226 allowing the pouring of concrete into these horizontal hollow posts 221.

[0086] Figure 1 1 shows a partial view of the wall 300 with the panel covering. The size of the first and second panels 100 is adapted to the window sill. The wall 300 also includes framing panels 130 which are arranged to form the internal walls of the opening 231 receiving the window. In addition, a first framing panel 130-1 and a second framing panel 130-2 extending horizontally are arranged above the opening. To provide insulation below the opening, a layer of insulation 210 extending horizontally is arranged between the first and second framing panels 130-1 and 130-2. The framing panels 130 include the same elements as the panels 100 but do not have the second insulating elements 106 or 126. [0087] Figure 10 shows another partial view of the wall 300 at the end of the wall 300 and which forms an angle with the adjacent wall. A hollow corner post 230 is arranged at the end of the alignment of the first posts 202-1. To improve the structure's resistance to deformation, particularly during storms or cyclones, the wall 300 includes a hollow reinforcing post 232, or bracing post. The hollow reinforcing post 232 opens at the level of the head of the hollow end post 230 and at the level of the foot of the hollow post 202-1 immediately adjacent to the hollow end post 230. Thus, concrete, reinforced or not with wires of steel, can be cast into the hollow reinforcing post 232. Preferably, the second insulating element 106 of the panel 100-1 mounted at the hollow end post 230 comprises a recess having the shape of the hollow reinforcing post 232 .

[0088] With reference to Figure 12, the first panels 100-1 are equipped with fixing means 301 configured to carry cladding or exterior facing elements of the structure. The fixing means 301 are arranged between the first panels 100-1 and are screwed to the first hollow posts 202-1. When the concrete is poured into the hollow posts, the fixing screws of the fixing means 301 are embedded in the concrete, allowing better fixing of the cladding.

[0089] Figure 13 shows different possible configurations of height of the walls of the structure. Figure 13a represents a wall with a height h1 corresponding to the length L2 of panels 100-1 and 100-2. It is possible to adapt this height by adding chaining panels 120-1 and 120-2, as shown in Figure 3. It is also possible to superimpose the chaining panels 120 with other chaining panels having a width L2 corresponding to the desired additional height. Figure 13b shows a slab in intermediate chaining concrete 402 surmounted by a row of first panels 400-1 and additional second panels 400-2, similar to the first panels 100-1 and second panels 100-2, but having a length different from the latter. These additional panels 400-1 and 400-2 make it possible to raise the wall to a height h2 greater than the height h1.

[0090] With reference to Figure 14, a variant of the wall is shown in which floor beams 422 are fixed to the second chaining panels 120-2 by fixing screws 420, for example which can be cast into the slab of chaining 402.

[0091] With reference to Figure 15, the second hollow posts 202-2 forming the internal face of the structure are provided with reinforcing wires 213 cast in concrete while the first hollow posts 202-1 forming the external face comprise only fiber-reinforced concrete. Thus, the first panels 100-1 can deform, as shown in Figure 15, to absorb the forces experienced by the structure due to wind or an earthquake. Conversely, the second panels 100-2 are rigid and do not deform, ensuring a stable interior space. The chaining reinforcement wires 214 embedded in the floor slab 220. The slab 216 also includes reinforcement wires 215.

[0092] With reference to Figures 16 and 17, another example of structure 500 is shown. The structure 500 comprises several wall parts 516 each comprising a first panel 100-1 and a second panel 100-2 and a common insulator 510 arranged between the first panel 100-1 and the second panel 100-2. The first panel 100- 1 is in particular arranged on the external side of the wall or external face of the structure 500 and the second panel 100-2 is in particular arranged on the internal side of the wall or internal face of the structure 500. The first panel 100-1 and the second panel 100-2 are advantageously glued on either side of the common insulator 510. The common insulator 510 comprises a first housing 512-1 capable of receiving one of the first hollow posts 202-1 and two half-housing 512-2 footprints. The half-housing indentations form an entire housing to receive one of the second hollow posts 202-2 when two successive common insulators are arranged side by side. The common insulator 510 comprises several recesses 514 forming housings provided for the passage of electrical cables or piping of said structure 500.

[0093] The structure 500 comprises several positioning shoes 502 mounted on the slab 216. Each positioning shoe 502 comprises a polymer plate, for example extruded polystyrene having a thickness of approximately 30 mm. Each positioning shoe 502 comprises a housing 503-2 for receiving one end of a second hollow post 202-2 and two half-housing indentations 503-1 which form a housing for receiving one end of a first hollow post 202- 1, when the positioning shoes are arranged side by side. The chaining wires 213 are pulled through the housings 503-2 and 503-1.

[0094] The positioning shoes 502 make it possible to align the wall parts and thus facilitate the assembly of the wall. In addition, the positioning shoes make it possible to improve the sealing at the level of the slab and to eliminate the thermal bridge between the slab and the wall.

[0095] Each positioning shoe 502 comprises at least one notch 505 provided to receive a connector 504 configured to connect two positioning shoes 502 together. The 504 connector has a bone shape. The connector 504 is in particular made of polymer, for example extruded polystyrene and has a thickness of approximately 30 mm. [0096] In particular, the positioning shoes 502 are glued to said slab 216 after the positioning of all the positioning shoes forming the periphery of the structure. After positioning the wall parts 516, the first and second posts 202-1 and 202-2 are slid into the corresponding housings 512-1 and 512-2.

[0097] For example, a cover similar to the positioning shoe can be arranged above the wall parts.

[0098] Props 508 are provided to hold the wall corner of the structure before pouring concrete into the hollow posts.
