Description

The invention relates to a method for treating thermal bridges between a floor and a wall adjacent to the floor. The invention also relates to a thermal insulation element and a structural floor connection element for implementing said method. The element also concerns a pre-slab equipped with such elements. The invention more particularly relates, but not exclusively, to a method of treating thermal bridges between a floor and a wall adjacent to one of the non-load bearing shores of said floor (as opposed to the floor bearing shores that take up the majority of the stresses applied to the floor. floor). BACKGROUND OF THE INVENTION There are two ways of dealing with the insulation of a building, either by enclosing the whole building in an insulating envelope, or by insulating inside a wall of which one side is in contact with the outside atmosphere.

In the case of interior insulation treatment, one of the main problems to be solved is that posed by the thermal bridges, that is to say that of the path of conduction of heat or cold by the continuity of a calorie-conducting material from the outside of the building to the interior. This is particularly the case for floors that form thermal bridges because of their contact with the external walls of the building. In an attempt to treat this type of thermal bridge wall / floor, it is known to arrange thermally insulating bodies between the wall and the floor, each body having reinforcements passing through the body so as to be prominent on both sides. other. After the compression slab has been poured to form the floor, the reinforcements protruding into the interior of the building are 3033809 2 coated so that they are rigidly secured to the floor. The reinforcements projecting from the other side of the thermally insulating body. are then in turn embedded in an external concrete element continuing the construction of the wall. In this way, the floor and the wall are rigidly connected and the thermally insulating bodies arranged between them limit the corresponding thermal bridges. Such thermally insulating bodies are for example described in patent EP 0 866 185.

However, the transport of such thermally insulating bodies from the production site to the building site concerned and the placing of said bodies on the site can prove to be tedious because of their large volume.

OBJECT OF THE INVENTION The object of the invention is to provide a method of treating thermal bridges between a floor and a wall adjacent to the floor that can be implemented easily.

SUMMARY OF THE INVENTION To this end, the invention relates to a method of treating thermal bridges between a floor and a wall adjacent to the floor, the method comprising the steps of: - bringing close to a portion of the floor wall, substantially at the level where a floor compression slab is to be cast, thermal insulation elements and structural connection members of the floor so as alternately to arrange a thermal insulation element and a structural connecting element on the floor. along the portion of the wall, each thermal insulation element comprising a block of thermally insulating material and each structural connecting element having at least reinforcements, each structural connecting element being arranged along the wall so that a first portion of the reinforcements of said structural connecting element is positioned above the portion of the wall and a second portion said reinforcements is positioned at the level of the future compression slab, 5 - pouring concrete to extend the portion of the wall so that the first portion of the reinforcement is found embedded in the concrete of the extension of the wall and pouring the concrete to form the slab compressing the floor so that the rest of said frames, and in particular the second portion of the frames, is embedded in the concrete floor. After pouring the compression slab to form the floor, the reinforcements are embedded in the compression slab so that they are rigidly attached to the floor. In addition, at their first portion, the reinforcements are also embedded in an external concrete element continuing construction of the wall. In this way, the floor and the wall are rigidly connected and the thermal insulation elements arranged between them limit the corresponding thermal bridges. The invention thus makes it possible to alternate the rigid connection zones between the floor and the wall with the thermal insulation zones. The reinforcements are therefore concentrated between the thermal insulation elements, at the level of the structural connection elements, so that the thermal insulation elements do not need to fulfill the function of anchoring the floor to the floor. In this way, the various insulation elements free of reinforcement simplify their handling and handling. In addition, since the thermal insulation elements and the structural connection elements need each to fulfill only one function, they are smaller in size, which makes them even easier to handle and handle. Wall. An operator can thus easily and quickly position the thermal insulation elements and the structural connection elements one after the other along the portion of the wall before pouring the concrete to bind the floor rigidly. and the wall. The method according to the invention is therefore simple and quick to implement. The invention also relates to a thermal insulation element for the implementation of the thermal bridge treatment method which has just been described and in which a lower portion of the block made of thermally insulating material comprises a tab which forms a longitudinal extension. of said lower portion and which is intended to receive the structural connecting element. Due to the particular shape of the thermal insulation element, the structural connecting element can be simply placed on the tab which facilitates its implementation along the portion of the wall. This further enhances the implementation of the process of the invention. In addition, the tab provides better thermal bridge treatment by being arranged between the wall and the floor at a rigid connection area between the floor and the wall. Such a tab ensures a continuity of the thermal insulation in the lower part of the floor between two thermal insulation elements separated by the structural connecting element resting on said tab.

According to a particular embodiment, the thermal insulation element comprises at least one receiving tray carrying the latching means of the thermal insulation element, the block of thermally insulating material being arranged in said receiving tray. - 35 tion.

According to a particular embodiment, a lower portion of the block of thermally insulating material of the thermal insulation element comprises a tab forming a longitudinal extension of the block, the structural connection element being then placed on or above said tab to be arranged along the wall. The invention also relates to a structural connection element for the implementation of the thermal bridge treatment method which has just been described, the structural connecting element comprising a concrete block, the reinforcements being anchored in the block in concrete so as to pass through said block so that the first portion and the second portion of the reinforcements are visible on either side of the block. Thus, the structural connecting element can be more simply placed between two thermal insulation elements thanks to the presence of the concrete block. This further enhances the implementation of the process of the invention. The invention also relates to a slab intended to support the concrete of a compression slab to constitute together with this slab of compression a floor, the slab comprising a concrete body and at least one thermal insulation element as mentioned above. secured to an edge of said pre-slab. Throughout this application, the terms "lower", "upper", "height", "length" should be understood in relation to the position of the floor and the corresponding wall portion once they are mounted. .

FIG. 14 is a perspective view of a thermal insulation element arranged between the floor and the portion of the wall illustrated in FIG. 13; FIG. 15 is a perspective view of a structural connection element arranged between the Floor 3033809 7 and the portion of the wall illustrated in Figure 13. DETAILED DESCRIPTION OF THE INVENTION With reference to Figures 1 to 6, the method according to a first embodiment of the invention is here to treat the thermal bridges between a floor 1 and a wall 2 adjacent to one of the non-load bearing banks of said floor. The process is implemented during construction of the building.

For this purpose, the wall 2 is mounted substantially to the level where the floor 1 is intended to be laid. Preferably, the upper portion of the mounted wall portion 3 has a stop 4 which allows a better junction with the continuation of the wall 2 to build as we will see later. P beams, supported by one or more props, are then positioned against the mounted portion 3 of the wall 2 so as to extend to the normal of said mounted portion 3 to serve as a support for the construction of the floor 1 Substrates (only one of which is referenced here) are successively joined to each other on the beams P to delimit the surface of the floor 1. One of the longitudinal edges 8 of at least one of the 25 pre-slats 5 , forming part of one of the non-bearing banks of the floor 1, here runs along the portion 3 of the wall 2 considered. FIG. 3 thus illustrates the already mounted portion 3 of the wall 2 and said slab 5. The slab 5 is mounted so that its longitudinal edge 8 extends along the mounted portion 3 of the wall 2 but with a relative offset to said portion 3. A space is left between the portion 3 and the predalle 5. With reference to Figure 4, is then arranged along said longitudinal edge 8 of said predalle 5 of the thermal insulation elements 6 and elements The structural element 7 of the floor 7 is arranged so as alternately to arrange a thermal insulation element 6 and a structural connection element 7. Thus, in the vicinity of the portion 3 of the wall 2, along said portion 3 5 wall 2, the various elements of thermal insulation 6 and structural connection 7 substantially at the level where a compression slab 9 of the floor 1 must be cast. More precisely here, the various elements of thermal insulation 6 and of structural connection 7 are arranged between said longitudinal edge 8 of the pre-slab 5 and the portion 3 of the wall 2 at the level of the space which has been left during the assembly step of the predalles. In a preferred manner, the various elements of thermal insulation 6 and of structural connection 7 are arranged so that one of their faces bears against the wall 2 (when it is completely assembled) and the opposite face correspondingly bear against the longitudinal edge 8 of the predalle 5. Preferably, the different elements of thermal insulation 6 and structural connection 7 are reported so as to join them to each other along the portion 3 of the wall 2. Said thermal insulation 6 and structural bonding elements 7 thus form a boundary between the predalle 5 and the corresponding wall portion 3 25. The various heat-insulating elements 6 and the various structural connection elements 7 are all elements that are independent of each other, which facilitates their handling, especially for arranging them between the longitudinal edge 8 of the slab 5 and the portion 2. wall 3 already built. All the structural connection elements 7 are here identical to each other and all the thermal insulation elements 6 are here identical to each other. In this way, the various thermal elements 6 and structural connection elements 5 together define a boundary between the 5 and the wall 2, the continuous boundary and the same along the longitudinal edge 8 of the 5 and therefore along the entire wall.

In particular, the various heat-insulating elements 6 are secured to the pre-slab 5. Preferably, the slab 5 comprises a concrete body, for example of pre-stressed concrete comprising longitudinally oriented prestressing cables and, in parallel, the to each other, and a border 10 anchored in said concrete body so as to form an edge of said body. The various thermal insulation elements 6 are here secured to this border 10 by interlocking in order to protrude from the upper face of the concrete body 15 of the predalle 5. With reference to FIG. 6, the edge 10 is rectilinear and extends along a straight line X corresponding here forming one to the longitudinal edge 8 of the predalle 5 non-load bearing banks of the floor 1. The way 10 has a cellular structure 11 of cellular structure which comprises cells in relief extending from the structure 11 towards the outside of the border in the direction of the pre-slab body 5.

The straight edge 10 thus proves to be not only flexible and flexible but also light. This facilitates the manipulation of the rim 10 and makes it easier to secure it to the concrete body of the pre-slab 5. In addition, it is possible to easily cut the rectilinear rim 10 to modify the length of the rim 10. depending on the production needs. This again facilitates the fixing of the rectilinear rim 10 to the predalle 5. The different cells are here open towards the outside of the rim 10 in the direction of the body of the prefabricated tilted head 20 prefabricated 5. The structure 11 is for example polypropylene. In particular, the structure 11 comprises a first row 12 of cells arranged side by side along the line X (one of the cells of the first row being symbolized in dotted lines and designated by 13). All the cells of the first row 12 are here contiguous. The structure 11 comprises a second row of cells 14 arranged side by side along the line X and placed side by side (one of the cells of the second row 14 being symbolized in dot-dashes and denoted by 15), each block of two contiguous cells (one of the blocks being symbolized in indents and designated 16) being separated by a space 17 of the next block of two contiguous cells. Thanks to the different spaces, the structure 11 is particularly flexible. The second row of cells 14 extends under the first row of cells 12 so that a cell of the second row 14 is in the extension of a respective cell of the first row 12. The second row of cells 14 Thus, the cells of the first row 12 are all identical to each other and the cells of the second row 14 are all identical to one another. In particular, the cells of the first row 12 and the cells of the second row 14 have the same length (dimension taken along the line X) and substantially the same width (dimension taken along a perpendicular line Y) on the line X and corresponding to the relief of the cells). The cells of the second row 14 here have a height greater than the cells of the first row 12 (dimension taken along a line Z perpendicular to the line X and the line Y).

In this way, all the cells of the structure 30 extend from one and the same main face of the structure 11. The other main face of the structure 11 then turns out to be free of cells and is therefore substantially smooth.

The structure 11 comprises, for example, 29 cells for the first row 12 and 20 cells for the second row 14. Preferably, the structure 11 has recesses 18 (only a part of which is referenced) passing through the structure 11 in its width. More specifically here a recess 18 passes through the structure 11 at the level of each of the cells of the second row 14 and at the level of each space 17 separating the blocks of two contiguous cells. The recesses 18 are arranged at the top of the cells of the second row 14 and associated spaces 17, substantially at the boundary between the first row of cells 12 and the second row of cells 14. The upper portion of the Structure 11 has clipping slots 19 (only a part of which is referenced) regularly distributed over the length of the structure 11 for the interlocking of the thermal insulation elements 6 on the edge 10. The clipping notches 19 are identical. The clipping slots 19 are here generated at the boundary between the first row of cells 12 and the second row of cells 14 by an inflection in the walls of the cells. At each boundary there is a clipping notch 19. When the thermal insulating members 6 are in place on the boundary 10, they thus cover the first row of cells 12. In particular, each notch of FIG. clipage 19 is surmounted by an anti-fouling nozzle 20 (only part of which is referenced). Anti-fouling nozzles 20 are all identical. The antifouling nozzles 20 are here formed in the walls of the first row of cells 12 so as to form a protuberance coming above the clipping notches 19. The antifouling nozzles 20 are further configured so as to be diagonally inclined. - 5 rection of the lower portion of the structure 11. The lower portion of the structure here comprises anchoring feet 21. The feet 21 are evenly distributed over the length of the structure 11. The feet 21 are identical. Each foot 21 extends here from a lower portion of the structure 11 towards the outside of the border 10 towards the lower portion of the body of the predalle 5. Each foot 21 extends in the extension of one of the two-cell common walls contiguous with the second row 14 (ie a wall of normal X line). Structure 1 here comprises a foot 21 at each block of two contiguous cells. The structure 11 comprises for example ten feet. In particular, the structure 11 comprises two wings 22 associated with each leg 21. Each wing 22 extends transversely to the foot 21 associated between a lower part of the foot 21 to the second row of cells 14. More specifically, each wing 22 extends from the lower part of the foot 21 to the outer wall of the block of two contiguous cells corresponding to said foot 21, outer wall parallel to the wall common to the two contiguous cells of said block. Here, the lower portion of the structure 11 comprises at least one positioning tab 23 of the border 10. More precisely, each positioning tongue 23 is arranged to extend to the normal of the structure 11 towards the outside the border 10 in the extension of the cells, in the direction of the width of the structure 11 (so here so as to extend along the line Z in the direction of the body of the predalle 2).

The structure here comprises several positioning tabs 23. For example, the structure 11 comprises two positioning tabs 23. The positioning tabs 23 are identical, extend from the same level of the lower portion and are distributed along the length of the structure 11. Each positioning tab 23 extends here from the lower portion of one of the spaces 17 between two contiguous cell blocks.

The two longitudinal ends (along the X axis) of the structure 11 respectively comprise male latching means 41 and female latching means 42, for example of the tenon / mortise type. In this way, it proves possible to simply snap together several edges 10 by snapping the female latching means 42 with the male latching means 41 of two consecutive edges 10. In particular, the border 10 comprises a magnet (not visible here) which is arranged on the main face of the structure 11 opposite to that from which the cells extend. The magnet is arranged to protrude from the remainder of said main face. More specifically here, the magnet is arranged below the said recesses 18 of the structure 11. Preferably, the magnet is in the form of a strip. The magnet is arranged so as to extend along the line X. The magnet thus makes it possible to cover the entire length of the structure 11.

The border 10 just described is preferably manufactured by injection. The border 10 is therefore simple and quick to manufacture. In particular, the rim 10 is manufactured in two stages: in a first step, the magnet is attached to an injection mold of the structure 11, in the second step the Structure 11 is formed and the magnet is simultaneously overmolded on the structure 11 so that the magnet and the structure 11 5 form an all-rigid. Typically to fix the edge 10 to the pre-slab 5, the edge 10 is installed in a mold for manufacturing the body of the slab 5 by being positioned along one of the longitudinal edges of this mold.

The feet 21 then come to rest on a bottom of the manufacturing mold. The feet 21 allow an operator to position the border 10 easily and quickly in the manufacturing mold by serving as a registration point.

Similarly, each positioning tab 23 is positioned in the manufacturing mold so as to extend just below the prestressing cables arranged in the manufacturing mold to be secured to the body of the pre-slab 5. The positioning tabs 20 23 thus also act as a reference point for the operator. It is therefore very simple to position the border 10 in the manufacturing mold and to check the correct positioning thereof by simply identifying whether the prestressing cables are well above the locating tabs 23 and if the feet 21 lie well on the bottom of the manufacturing mold. The concrete is then poured into the manufacturing mold to form the body of the pre-slab 5.

The anti-fouling nozzles 20 make it possible to protect the clipping notches 19 during casting of the body of the floor 5 and in particular of the concrete that could accidentally be thrown towards said clipping notches 19. This prevents concrete from congealing in the notches This advantage would be detrimental to subsequent embolization of the thermal insulating elements 6 on said rim 10. Advantageously, the recesses 18 make it possible to ensure a balancing of the pressures experienced by the rim. 10 when pouring concrete. The recesses 18 are of course arranged so as to be arranged at a height of the structure 11 greater than the height of the body of the slab 5 so that concrete can not penetrate through the recesses 18 between the manufacturing mold 10 and the edge 10. Furthermore, the magnet makes it possible at the same time to position the edge 10 in the manufacturing mold, as well as the feet 21 or the positioning tongues 23, but also to maintain the edge 10 in position, even during pouring of the concrete, placing it against the associated bank. Indeed, when the edge 10 is arranged in the manufacturing mold, the magnet makes it possible to firmly press the edge 10 against the edge by adhering to the forming mold. This prevents infiltration of the concrete between the rim 10 and the manufacturing mold at the upper portion of the rim 10 during casting of the body which could hinder subsequent engagement of the thermal insulation elements 6 on said rim 10.

Due to its elongated shape, the magnet also makes it possible to cover the entire length of the structure and thus to fully press the entire edge 10 against the manufacturing mold. Of course, the border 10 is shaped so as to be able to match the shape of the manufacturing mold so that its plating by the magnet is possible. In the case of a chamfer between the bottom of the mold and the side walls of the mold, the feet 21 are thus inclined relative to the remainder of the structure 11 to be able to marry the inclination of said chamfer.

3033809 16 Once the concrete has been poured and finished taking, the edge 10 is then rigidly secured to the pre-slab body 5 so as to form with it an all-rigid. The pre-slab 5 can then be removed from the production mold. In this way, the rim 10 is easily and quickly secured to the body of the pre-slab 5 by overmolding during manufacture of said body. With reference to FIG. 3, the edge 10 is thus rigidly secured to the concrete body of the pre-slab 5 while being anchored therein. The lower portion of the rim 10, corresponding to that of the structure 11 and extending from the feet 21 to substantially the level of the recesses 18 without however attaining it, is embedded in the concrete of the body 5. The edge 10 is thus arranged so that the cells extend towards the inside of the pre-slab 5. Part of the cells are thus partially embedded in the concrete of the slab body 5. The smooth main face the edge 10 forms the free surface of the pre-slab 5 and thus the longitudinal edge 8 of the slab 5. The upper portion of the structure 11, corresponding to that of the rim 10, therefore protrudes from the upper face of the body The thermal insulation elements 6 can then be fitted on said upper portion. With reference to FIG. 1, one of these thermal insulation elements 6 according to the first embodiment of the invention will now be described. The thermal insulation element 6 comprises a block of thermally insulating material. Said block is for example mineral wool.

A lower portion of said block has a tab 23 (or tab) forming a longitudinal extension of the block. The tab 23 is integral with the rest of the block. The block is therefore roughly L-shaped with a main portion 24 of substantially parallelepipedal shape and a secondary portion formed of the longitudinal extension 23. The lug 23 therefore has a height less than the height of the main portion 24. The tab 23 has a width identical to that of the main part 24. The tab 23 here has a length less than the length of the main part 24. For example, the tab 23 to a length of between 20 and 40 centimeters and the main part 24 has a length between 70 and 110 centimeters. The main part 24 has a height substantially equal here to the total height of the floor 1. In this way, when the thermal insulation element 6 is fitted on the edge 10, the upper face of the element 20 of thermal insulation 6 is substantially height of the compression slab 9 casting on the predalle 5 as we will see later. Preferably, the tab 23 is configured so as to have a height equal to the height of the body 25 of the predalle 5. Preferably, the thermal insulation element 6 comprises a plate 25, the block of thermally insulating material being secured to said plate 25. For this purpose, the thermal insulation element 6 comprises two straps 26 jointly surrounding the main portion 24 of the block of thermally insulating material and the plate 25 so as to fix said block to said plate 25. The plate 25 is for example metal. Typically the plate 25 is made of steel.

Preferably, the plate 25 is substantially identical in shape to that of the thermally insulating material block to conform to the contours of said block when secured together. The plate 25 carries here latching means 27 able to cooperate with corresponding latching means (here the clipping notches 19) of the edge 10 of the predalle 5 for the interlocking of the element of FIG. thermal insulation 6 on said border 10. The latching means 27 of the thermal insulation element are here referred to the plate 25. Said latching means 27 here comprise two slightly elastically deformable fingers each comprising a portion of shaped hook Z, one of the edges of the Z snap into two successive clipping notches 19 of the edge 10 15 to secure the thermal insulation element 6 to the predalle 5. With reference to Figure 2, the one of the structural connection elements 7 according to the first embodiment of the invention will now be described.

The structural connecting element 7 here comprises a block 28 of concrete comprising reinforcements 29 passing through said block so as to protrude on either side of the block 28. The reinforcements 29 are embedded in the concrete of the block 28 of FIG. the structural connecting element 7 so that the plates 29 and said block 28 form an all-rigid. The frames 29 are for example steel. Preferably, the block 28 of the structural connecting element 7 is configured to be placed on the lug 23 of one of the thermal insulation elements 6. Thus, the block 28 of the structural connecting element 7 is here shaped in a rectangular parallelepiped of the same width and the same length as the corresponding tab 23. The block 28 of the structural connecting element 7 has a height 35 such that the sum of the height of the block 28 of the structural connection element 7 and the height of the lug 23 corresponds substantially to the height of the main portion 24 of the block of thermally insulating material of the associated thermal insulation element 6.

The structural connecting element 7 is thus configured so that the sum of the height of the block 28 of said structural connecting element 7 and the height of the associated tab 23 is substantially equal to the total height of the floor 1.

In this way, when the structural connecting element 7 is placed on the lug 23 of the associated thermal insulation element 6, the upper face of the structural connecting element 7 is substantially at the height of the slab. compression 9 cast on the pre-slab 5 as we will see later. The reinforcements 29 are, of course, arranged so as to be at a height greater than that of the edge 10 anchored in the body of the slab 5, when the structural connecting element 7 is placed on the tab 23, for extend on one side towards the predalle 5 above the predalle 5 and on the other side towards the wall 2 above at least a portion of the portion 3 of the wall 2 already built. Preferably, the concrete of the block 28 of the structural connecting element 7 is a concrete having a thermal conductivity of less than 1 watt per meter-Kelvin. The concrete of the block 28 of the structural connecting element 7 thus has a reduced thermal conductivity. In this way, the structural connecting element 7 is also actively involved in the treatment of the thermal bridges that can form between the wall 2 and the floor 1. Here, the concrete of the block 28 of the structural connecting element 7 is a concrete having a thermal conductivity of less than 0.6 watts per meter-Kelvin which further enhances the treatment of thermal bridges by the structural connecting element 7. For example, Thermedia concrete (registered trademark) is used as the concrete. by Lafarge).

In this way, with reference to FIG. 4, when the operator wishes to arrange the thermal insulation elements 6 and the structural connection elements 7 along the portion 2 of the wall 3, he successively performs the following steps: - interlocking of a thermal insulation element 6 as previously described on the edge 10 of the predalle 5, the tab 23 of the thermal insulation element defining the space between the two main parts 24 of two elements d consecutive thermal insulation, - removal of a structural connecting element 7 as previously described on the tab of one of the thermal insulation elements so that the reinforcements 29 projecting from one side of the structural connecting element 20 7 are positioned above at least a portion of the portion 2 of the wall 3 and the reinforcements 29 projecting from the other side of the structural connecting element 7 are positioned above the vs concrete orps of the predalle 5.

It should be noted that, unlike the thermal insulation elements 6, the structural connection elements 7 are not secured to the floor 5 but only laid along the longitudinal edge 8 of the pre-slab 5.

It is therefore very simple for an operator to arrange the various elements of thermal insulation 6 and structural connection 7 along the wall 2 while ensuring their good positioning since it is sufficient for the operator to a thermal insulation element 6 is fitted on the edge 10 already in place on the pre-slab 5 and then a structural connecting element 7 is placed on the lug of the thermal insulation element 6 already in place as well. Advantageously, the thermal insulation elements 6, the structural connection elements 7 and the border 10 together constitute a formwork portion of a compression slab 9 intended to be cast on the pre-slab 5. The implementation of the The formwork of the compression slab 9 proves to be very simple thanks to the invention 10 by simply snapping the thermal insulating elements 6 onto the edge 10 of the slab 5. The joining of the various blocks between them makes it possible to ensure good formwork of the compression slab 9. Therefore, with reference to FIG. 5, it remains only to form the compression slab 9 by casting concrete on the pre-slab 5 so that the reinforcements 29 protrusion of the structural connecting element 7 extending above the predalle 5 are found embedded in the concrete. The compression slab 9 is cast so as to come to the height of the various structural connection elements 7 and thermal insulation 6 along the wall 2. Concrete is also poured over the wall portion 3 of the wall 2 already existing to continue the construction of the wall 2 so that the reinforcements 29 fly on the other side of the structural connecting element 7 (and which extend above the portion 2 of the wall 3 already built ) are also embedded in the concrete. The reinforcements 29 are thus anchored on one side in the floor 1 and on the other side in the wall 2 which ensures the lift of the floor 1. Moreover, the thermal bridges that can form between the floor 1 and the wall 2 are very limited since the thermal insulation elements 6 form a thermal insulation barrier between the floor 3033809 22 1 and the wall 2 being arranged between the floor 1 and the wall 2 over substantially the entire height. floor 1 (as clearly visible in Figures 4 and 5). In addition, the thermal bridges are further limited by the presence of the tab 23 of a height substantially equal to the height of the pre-slab 5 participating in the formation of a continuous thermal insulation barrier between the floor 1 and the wall 2: the entire lower portion of the floor 1 (corresponding substantially to the height of the predalle 5) is thus thermally insulated from the wall 2. In addition, the thermal bridges are further limited by the fact that use of a particular concrete for the structural connecting elements 7, concrete which is much more thermally insulating than the concretes traditionally used in the field of buildings and which have a thermal conductivity of at least 2 watts per meter-Kelvin . The structural connection elements 7 thus also participate in the formation of a thermal insulation barrier between the floor 1 and the wall 2. The thermal bridges that can form between the floor 1 and the wall 2 thus prove to be extremely small. here all along the wall 2 considered and over the entire height of the floor 1.

Furthermore, the joining of the various elements of structural connection 7 and thermal insulation 6 makes it possible at the same time to ensure good thermal insulation of the floor 1 at the level of the wall 2 and at the same time to ensure good floor lift 1.

In addition, the use of mineral wool for the blocks of the thermal insulation elements 6 allows, in addition to the thermal insulation function, to fulfill an additional function of fire protection as well as an additional function of acoustic insulation. It should be noted that the presence of the 3033809 23 tab 23 on the thermal insulation elements 6 improves these fire protection and sound insulation functions at the lower portion of the floor 1.

In addition, because the thermal insulation elements 6 are secured by interlocking with the edge 10 and the structural connecting elements 7 are positioned on the tabs 23 of the thermal insulation elements 6, it is possible to 10 to overcome a relatively large conventional smooth support of the prior art. A simple beam support of the predalle 5 is sufficient here. A first non-limiting implementation of the method according to the invention has just been described. Figure 7 illustrates a first variant of this first implementation. In this variant, the various elements of thermal insulation 6 are not this time provided with a tab. Apart from the absence of a tab, the various thermal insulation elements 6 are identical to those previously described. Thus, the thermal insulation element 6 comprises a block 30 of thermally insulating material. Said block 30 is for example mineral wool.

The block 30 thus has here simply a form of parallelepiped rectangle. Block 30 has a height substantially equal here to the total height of the floor. In this way, when the thermal insulation element 6 is fitted on the terminal 10 anchored in the pre-slab 5, the upper face of the structural connecting element 7 is at approximately the height of the compression slab cast on the pre-slab. Preferably, the thermal insulation element 6 comprises a plate 31, the block 30 made of heat-insulating material 3033809 being secured to said plate 31. For this purpose, the thermal insulation element 6 comprises two straps (of which a single strap 32 is visible here) jointly surrounding the block 30 of thermally insulating material and the plate 31 so as to fix said block 30 to said plate 31. The plate 31 is for example metal. Typically the plate 31 is made of steel. Preferably, the plate 31 has a shape substantially identical to that of the block 30 of thermally insulating material to conform to the contours of said block 30 when they are joined together. The plate 31 carries here latching means 40 adapted to cooperate with corresponding latching means (here the clipping notches 19) of the edge 10 of the pre-slab 5 for the interlocking of the element. thermal insulation 6 on said border 10. The latching means 40 of the thermal insulation element 6 are here referred to the plate 31. Said latching means 40 here comprise two slightly elastically deformable fingers each comprising a portion shaped fastening Z, one of the edges of the Z snap into two successive clipping notches 19 of the edge 10 to secure the element 25 of thermal insulation 6 to the predalle 5. Because of the absence on which the structural connection elements 7 of the variant described are shaped so as to be also secured to the pre-slab 5. For this purpose, the structural connecting element 7 comprises a block 33 made of concrete and latching means 43 adapted to cooperate with corresponding latching means (here the notches 19 clipping) of the edge 10 of the predalle 5 for the interlocking of the structural connecting element 7 on said border 10. The The latching means 43 of the structural connecting element element 7 are here referred to in the block 33. Said detent means 43 here comprise two slightly elastically deformable fingers each comprising a fastening portion shaped in Z-shape. , one of the edges of the Z snap into two successive clipping notches 19 of the edge 10 to secure the structural connecting element 7 to the pre-slab 5. In addition, as previously described, the block 33 10 concrete comprises reinforcements 34 passing through said block 33 so as to protrude on either side of the block 33. Thus, the block 33 of the structural connecting element 7 is here shaped in a rectangular parallelepiped. The block 33 of the structural connecting element 7 has a height substantially identical to the height of the block 30 of thermally insulating material of the associated thermal insulation element 6. The structural connecting element 7 is thus configured to have a height substantially identical to the total height of the floor. In this way, when the structural connecting element 7 is secured to the edge 10 of the predalle 5, between the edge 10 and the wall portion 2, the upper face of the structural connecting element 7 is at a height substantially the compression slab cast on the predalle 5. The frames 34 are of course arranged to be at a height greater than that of the edge 10 anchored in the body of the predalle 5, when the element 7 is arranged along the edge 10, to extend on one side in the direction of the slab 5 above the slab 5 and on the other side towards the wall 2 above at least a portion of the portion 3 of the wall 2 already constructed.

The reinforcements 34 are embedded in the concrete of the block 33 of the structural connecting element 7 so that the plates 34 and said block 33 form an all-rigid. The frames 34 are for example made of steel, typically made of stainless steel. In a preferred manner, the concrete of the block 33 of the structural connecting element 7 is a concrete having a thermal conductivity of less than 1 watt per meter-kelvin. The concrete of the block 33 of the structural connecting element 10 therefore has a reduced thermal conductivity. Here, the concrete of the block 33 of the structural connecting element 7 is a concrete with a thermal conductivity lower than 0.6 watts per meter-Kelvin, which further enhances the treatment of thermal bridges by the structural connecting element 7 A second variant of the first implementation of the method according to the invention will now be described with reference to FIGS. 8 to 12.

The thermal insulation elements 6 are here identical to the thermal insulation elements 6 described in connection with the first implementation of the method according to the invention and FIGS. 1 to 6. Each thermal insulation element 6 thus comprises 25 a block of thermally insulating material. Said block is for example mineral wool. A lower portion of said block has a tab 50 (or tongue) forming a longitudinal extension of the block. The tab 50 is integral with the remainder of the block. The block is therefore roughly L-shaped with a main portion 51 of substantially parallelepipedal shape and a secondary portion formed of the longitudinal extension.

The tab 50 therefore has a lower height 3033809 27 at the height of the main part 51. The tab 50 has a width identical to that of the main part 51. The tab 50 here has a length less than the length of the main part. . For example, the tab 50 has a length of between 20 and 40 centimeters and the main portion 51 has a length of between 70 and 110 centimeters. The main part 51 has a height substantially equal here to the total height of the floor 1. In this way, when the thermal insulation element 6 is engaged on the edge 10, the upper face of the element of thermal insulation 6 is substantially at the height of the compression slab 9 cast on the predalle 5. Preferably, the tab 50 is configured so as to have a height equal to the height of the body of the predalle 5. Preferably, each thermal insulation element 6 comprises a plate 52, the block of thermally insulating material being secured to said plate 52. To this end, the thermal insulation element 6 comprises two straps 53 jointly surrounding the main part 51 of the block. thermally insulating material and the plate 52 so as to fix said block to said plate. The plate 52 is for example metal. Typically the plate 52 is made of steel. Preferably, the plate 52 has a shape substantially identical to that of the block of thermally insulating material to conform to the contours of said block when they are joined together.

The plate 52 here carries latching means 54 able to cooperate with corresponding latching means (here the clipping notches) of the edge 10 of the slab 5 for the interlocking of the thermal insulation element 6. on said border. The snap-fastening means 54 of the thermal insulation member 30 are referred to herein as the plate. Said detent means here comprise two slightly elastically deformable fingers each comprising a fastening portion shaped in Z, one of the edges of the Z being snapped into two successive clipping notches of the edge 10 to secure the element However, in this second variant of the first embodiment of the invention, the various structural connection elements 7 do not comprise a concrete block. Referring to Figure 9, each structural connecting element 7 comprises reinforcements 55. The armatures 55 are for example steel.

Preferably, the structural connecting element 7 is configured to be placed on the lug 23 of one of the thermal insulation elements 6. In this way, with reference to FIG. 10, when the operator wishes to assemble the floor 1, it has already 20 put the predalles 5 on the support beams P. Then, with reference to FIG. 11, the operator arranges the thermal insulation elements 6 and the structural connection elements 7 along the portion of the wall by successively performing the following steps: - interlocking an element of thermal insulation 6 as previously described on the edge 10 of the predalle 5, the tab 50 of the thermal insulation element 6 then defining the space separating the two main parts 51 of two thermal insulating elements 6 consecutive, - removal of a structural connecting element 7 as previously described on the tab 50 of one of the thermal insulation elements 6 so that a portion of the armatures 55 are positioned above 35 at least part of the portion of the wall 3 and another portion of the reinforcements 55 are positioned above the concrete body of the predalle 5. Referring to Figure 12, it remains only to form the slab compression 9 by pouring concrete 5 on the pre-slab 5 so that the portion of the reinforcements 55 extending above the pre-slab 5 and between the thermal insulation elements 6 is embedded in the concrete. The compression slab 9 is cast so as to come up to the different thermal insulating elements 6 along the wall. Concrete is also poured over the already existing wall portion 3 to continue the construction of the wall 2 so that the portion of the reinforcement 55 that extends above the portion of the already constructed wall 3 is also found. drowned in concrete. The reinforcements 55 are thus anchored on one side in the floor 1 and on the other side in the wall 2 which ensures the lift of the floor 1. Note that in this second variant, the legs 20 of the elements of thermal insulation 6 not only facilitate the positioning of the various elements but also form a formwork for the portion of the frames 55 arranged between the thermal insulation elements 6. This simplifies the manufacture of the floor 1. The first variant illustrated in Figure 7 in connection with the first implementation is also applicable here so that the second variant may also include thermal insulation elements 106 not including tab 50. A second implementation of the method according to the invention will be present described with reference to Figures 13 to 15. The elements in common with the first implementation retain the same numbering increased by a hundred.

In contrast to the first embodiment in which the floor 1 was a floor to floor, the floor 101 of the second implementation is a floor with full slab.

As a result, the wall 102 is mounted substantially to the level where the floor 101 is to be laid. Preferably, the upper portion of the wall portion already mounted has a stop that allows a better connection with the continuation of the wall to build.

A smooth support for the construction of the floor 101 is then positioned against the mounted portion of the wall 102. Then, along the wall 102, heat insulation elements 106 and 15 structural link 107 so as alternately to arrange a thermal insulation element 106 and a structural connecting element 107 along said wall 102. Thus, close to the portion of the wall 102, along said portion, the different elements of thermal insulation 106 and structural link 107 substantially at the level where a compression slab 109 of the floor 101 is to be cast. In a preferred manner, the various elements of thermal insulation 106 and of structural connection 107 are arranged so as to have one of their faces bearing against the wall 102 (when the latter is completely assembled). Each thermal insulation element 106 comprises a block of thermally insulating material. Said block is for example mineral wool.

A lower portion of said block comprises a tab 123 (or tongue) forming a longitudinal extension of the block. Leg 123 is integral with the rest of the block. The block is therefore roughly L-shaped with a main portion 124 of substantially parallelepipedal shape and a secondary portion formed of the tab 123. The tab 123 thus has a height less than the height of the main portion 124. The tab 123 has a width identical to that of the main part 124. The tab 123 here has a length less than the length of the main part 124. For example, the tab 123 has a length of between 20 and 40 centimeters and the main portion 124 has a length of between 70 10 and 110 centimeters. The main portion 124 has a height substantially equal here to the total height of the floor 101. In this way, the upper face of the heat insulating member 106 is substantially height of the casting slab 109 cast. It should be noted that, contrary to the first implementation and to its variant, the thermal insulation element 106 does not comprise any plate, strap or locking means. This is explained by the fact that the thermal insulation element 106 is simply arranged along the wall but is not secured to any pre-slab or other part of the already assembled building. Furthermore, each structural connecting element 107 here comprises a concrete block 128 comprising reinforcements 129 passing through said block 128 so as to protrude on either side of the block 128. The reinforcements 129 are embedded in the concrete of the block 128 of the structural connecting member 107 so that the armatures 129 and said block 128 form an all-rigid. The armatures 129 are for example steel, typically stainless steel. Preferably, the block 128 of the structural connecting element 107 is configured to be placed on the tab 123 of one of the thermal insulation elements 106.

Thus, the block 128 of the structural connecting element 3033809 32 107 is here shaped into a rectangular parallelepiped of the same width and length as the corresponding tab 123. The block 128 of the structural connecting element 107 has a height such that the sum of the height of the block 128 of the structural connecting element 107 and the height of the leg 123 substantially corresponds to the height of the main part. 124 of the block of thermally insulating material of the associated thermal insulation element 106.

The structural connecting member 107 is thus configured such that the sum of the height of the block 128 of said structural connecting member 107 and the height of the tab 123 is substantially equal to the total height of the floor 101.

In this way, when the structural connecting element 107 is placed on the tab 123 of the associated thermal insulation element 106, the upper face of the structural connecting element 107 is substantially at the height of the slab. compression casting 109.

Preferably, the concrete of the block 128 of the structural connecting member 107 is a concrete having a thermal conductivity of less than 1 watt per meter-Kelvin. The concrete of the block 128 of the structural connecting member 107 thus has a reduced thermal conductivity. Here, the concrete of the block 128 of the structural connecting member 107 is a concrete with a thermal conductivity of less than 0.6 watts per meter-Kelvin which further enhances the treatment of the thermal bridges by the structural connecting element 107. in this way, when the operator wishes to arrange the thermal insulation elements 106 and the structural connection elements 107 along the portion 3 of the wall 2, he successively performs the following steps: - removal of an insulation element As previously described along the wall 2, the tab 123 of the thermal insulation element then defines the space separating the two main portions 124 from two consecutive thermal insulation elements. a structural connection element 107 as previously described on the tab 123 of one of the thermal insulation elements 106 so that the armatures 129 project on one side of the elements The structural connecting members 107 are positioned above the wall portion 2 of the wall 3 and the ribs 129 projecting from the other side of the structural connecting members 107 are positioned above the support. Therefore, it remains only to form the compression slab 109 by casting concrete so that the reinforcements 129 projecting from the structural connecting element 107 extending above the support are found embedded. in the concrete. The compression slab 109 is cast so as to come to the height of the various structural connection elements 107 and thermal insulation 106 20 along the wall 102. Concrete is also poured over the wall portion 103 already existing to continue the construction of the wall 102 so that the projecting armatures 129 on the other side of the structural connecting member 107 (and extending above the wall 102) are also embedded in the concrete. The armatures 129 are thus anchored on one side in the floor 101 and on the other side in the wall 102 which ensures the lift of the floor 101.

Moreover, the thermal bridges that can form between the floor 101 and the wall 102 are very limited since the thermal insulation elements 106 form a thermal insulation barrier between the floor 101 and the wall 102 being arranged between the Floor 101 and wall 102 over substantially the entire height of the floor 101. In addition, the thermal bridges are further limited by the presence of the tab 123 participating in the formation of a continuous thermal insulation barrier between the floor 101 and the wall 102: 5 the entire lower portion of the floor 101 is thus thermally insulated from the wall 102. In addition, the thermal bridges are further limited because of the use of a particular concrete for the elements structural bond 107, which is much more thermally insulating than concretes traditionally used in the field of buildings and which have a thermal conductivity at least 2 watts per meter-Kelvin. The structural connection elements 107 thus also contribute to the formation of a thermal insulation barrier between the floor 101 and the wall 102. The thermal bridges that can form between the floor 101 and the wall 102 thus prove to be extremely reduced here all along the wall 102 considered and over the entire height of the floor 101.

Furthermore, the joining of the various structural connection elements 107 and thermal insulation 106 makes it possible both to ensure good thermal insulation of the floor 101 at the wall 102 and at the same time to ensure good lift of the floor 101.

In addition, the use of mineral wool for the blocks of the thermal insulation elements 106 makes it possible, in addition to the thermal insulation function, to perform an additional function of fire protection as well as an additional function of acoustic insulation. It should be noted that the presence of the tab 123 on the thermal insulation elements improves these fire protection and sound insulation functions at the lower portion of the floor 101.

A second nonlimiting implementation of the invention according to the invention has just been described. The first variant illustrated in FIG. 7 in relation to the first implementation is also applicable here so that the second implementation may also include thermal insulation elements 106 that do not include a tab. Similarly, the second variant illustrated in FIGS. 8 to 12 in relation to the first embodiment is also applicable here so that the second implementation may also comprise structural connection elements 107 not comprising a concrete block. . Naturally, the invention is not limited to the implementations described and variant embodiments can be made without departing from the scope of the invention as defined by the claims. Although here the various elements are secured to the predalle once the predalle in place against the wall, the various elements can be secured to the predalle before the installation of the predalle 20 against the wall (eg directly on the production site of the pre-slab or at the building's manufacturing site before mounting the slab). Although here the predalle has only one edge, the predalle may have a greater number of edges to form one of its edges. The successive borders intended to form an edge of the predalle may either be nested to each other at their ends, or be contiguous to each other without being nested or separated by a space. The borders may be cut to a desired length to form the edge of the predalle so that the cut end has no latching means unlike the half-formed end, one of the cells is not complete. after

Claims (22)

REVENDICATIONS1. The border may be different from what has been described. The second row of cells may thus contain only cells contiguous to each other. The first row of cells and the second row of cells will then have the same number of cells. The tabs will then extend under one of the cells of the second row, a cell not associated with an anchor foot. Alternatively, the border may not include feet, tongue _ The cells, feet, tabs, antifouling nozzles, clipping notches may not all be identical. The border may have a different number of rows of cells. The cells will not necessarily be organized in a row. The border may not have a magnet. In this case, the edge may simply be placed in the mold of the pre-slab body being positioned along the edges of this mold and possibly being simply held in position by external holding members. Although here, the edge is secured to the body of the predalle overmoulding during the manufacture of said body, it may be secured to the pre-slab body differently for example by fastening elements of the screw type or otherwise. Although here the border has a honeycomb structure of plastic material, the border may be in another material, for example concrete or metal. Each of the variants of the thermal insulation elements may be associated with any of the aforementioned borders. Likewise, each of the variants of the structural connecting elements may be associated with any of the aforementioned borders. The thermal insulation element can thus be secured to the predalle differently than what has been described. For example, the thermal insulation element may comprise at least one receiving tray in which the block of thermally insulating material will be arranged, the thermal insulation element then being secured to the edge by interlocking the receiving tray with said border so that the thermal insulation element 10 extends between the wall and the edge. The thermal insulation element can be secured to the predalle other than by interlocking with the predalle edge. The predalle may thus have no border. The thermal insulation element can thus be secured to the predalle by gluing, screwing Alternatively, the thermal insulation element can simply be arranged between the predalle and the wall without being secured to the edge. Likewise, regardless of the type of floor under consideration, the thermal insulation element may be different from what has been described. Thus, the block of the thermal insulation element may be in a material different from what has been described, for example, based on polystyrene, based on expanded polystyrene, based on mineral wool, based on perlite. Although here the tab of the block of the thermal insulation element is integral with the rest of said block, the tab may form an element independent of the rest of the block but fixed to the block (by screwing, by gluing so that the tab and the rest of the block form an all-rigid.When the thermal insulation element comprises a plate carrying the latching means, said plate may not be of a shape identical to that of the block 35 of corresponding thermally insulating material The plate may be secured differently to the block than by a strap for example by gluing or screwing or with the aid of an elastic.The thermal insulation element may not include of plaq In this case, if the thermal insulation element comprises means for latching or interlocking with the predalle, the latching means may be directly attached to the block of the thermal insulation element, for example by gluing or by face. The block of the thermal insulation element 10 may in this case be based on expanded perlite. In addition, although here the various elements of thermal insulation are all identical to each other along the same wall, the various thermal insulation elements may of course be different from each other along the same wall. For example, some thermal insulation elements may include a tab as illustrated in Figure 1 and other not include as illustrated in Figure 7. The thermal insulation elements may be of different sizes between them including 20 different length. Some thermal insulation elements may be formed of a single block of thermally insulating material and other of several blocks of thermally insulating material joined together. In the case of a floor pre-slab, some elements may be secured to the predalle and others only arranged along the predalle without being secured. Also, regardless of the type of floor considered, the structural connecting element may be different from what has been described. The structural connecting element may not be arranged along the wall by being placed on the leg of the adjoining thermal insulation element, but rest directly on a support of the bar for mounting the floor (floor with floor or floor solid slab 3033809 39) or be secured to a slab (floor slab). In the latter case, the structural connecting element may be secured to the predalle by interlocking at the edge of the predalle. For this purpose, the structural connecting element may comprise snap-fastening means capable of cooperating with corresponding latching means of the edge (such as clipping notches of the edge) anchored in the pre-slab. The structural connecting element may comprise at least one receiving tray in which the concrete block is arranged, the structural connecting element then being secured to the edge by interlocking of said receiving tray at the edge. The structural connecting element may be secured to the predalle other than by interlocking with the predalle rim. The predalle may thus have no border. The structural connection element can thus be secured to the predalle by gluing, screwing ... Alternatively, the structural connecting element can simply be arranged between the pre-slab and the wall without being secured to the edge. The concrete block of the structural connecting element may be of a material different from what has been described. For example, the concrete of the block of the structural connecting element may be a very high performance concrete. The selected concrete may thus have a compressive strength greater than 80 MegaPascal. This will strengthen the structural support provided to the floor and in particular allow the building concerned to comply with the seismic standards in force. Concrete Ductal (trademark registered by Lafarge) will be used for example as concrete. As a variant, the concrete of the block of the structural connecting element may be a high-performance concrete or an ultra-high performance concrete. Furthermore, although here the various elements of the structural connection are all identical to each other along the same wall, the different structural connection elements can of course be different from each other along the same wall. For example, some structural connecting elements may be arranged on the legs of the thermal insulation elements and other be arranged directly along the wall without resting on such tabs. The structural connection elements may be of different sizes to each other, in particular of different lengths. In the case of a floor with pre-slabs, some elements may be secured to the predalle and others only arranged along the predalle. Similarly, regardless of the type of floor considered, although here the concrete is first poured to the floor before being poured at the wall, it will of course be possible to pour the concrete first from the wall to continue the construction of the wall before pouring concrete at floor level. In addition, although here the different elements are joined to each other, it will be possible to arrange the different elements so as to leave a slight space between two consecutive elements. It will also be possible to secure the various elements together once they are joined together and arranged along the wall (by gluing or screwing for example). Although here the different elements are all independent of each other before their assembly along the wall, it is possible to consider joining one or more elements together in a first time and then arrange said assembly along the wall in a second time instead of joining them to each other once they are already arranged along the wall. Structural connection elements such as thermal insulation elements may also have an additional layer of fire protection such as a mineral wool layer. As a variant, the material of the blocks of the various structural connection elements, such as the material of the thermal insulation elements, can themselves provide a function of protection against fires. Although here the method according to the invention has been implemented for the treatment of thermal bridges between the non-load bearing edge of the floor and the wall adjacent to said bank, the method may also be used for the treatment of bridges. between a bearing bank of the floor and a wall adjacent to said bank. For the same building, it is possible to use the method according to the invention to isolate the floor, at its two non-supporting edges, from the adjacent walls and to implement a method of the prior art for isolating the floor, at its two supporting banks, adjacent walls.
