Description

The invention also relates to a thermal insulation element and a structural connection element of the floor for carrying out said method. The element also concerns a pre-slab equipped with such elements.

L'invention concerne plus particulièrement bien que non exclusivement un procédé de traitement de ponts thermiques entre un plancher et un mur adjacent à l'une des rives non porteuse dudit plancher (par opposition aux rives porteuses du plancher qui reprennent la majorité des efforts appliqués au plancher).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).

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il existe deux manières de traiter l'isolation d'un bâtiment, soit en enfermant l'ensemble de la construction dans une enveloppe isolante, soit en pratiquant une isolation à l'intérieur d'un mur dont une face est au contact avec l'atmosphère extérieure.There are two ways of treating the insulation of a building, either by enclosing the entire building in an insulating envelope, or by insulating inside a wall, one side of which is in contact with the building. outside atmosphere.

Dans le cas du traitement de l'isolation par l'intérieur, l'un des principaux problèmes à résoudre est celui posé par les ponts thermiques, c'est-à-dire celui du chemin de conduction de la chaleur ou du froid par la continuité d'un matériau conducteur de calorie depuis l'extérieur du bâtiment jusqu'à l'intérieur. C'est notamment le cas des planchers qui forment des ponts thermiques du fait de leur contact avec les murs extérieurs du bâtiment.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 exterior walls of the building.

Pour tenter de traiter ce type de pont thermique mur/plancher, il est connu d'agencer des corps thermiquement isolant entre le mur et le plancher, chaque corps comportant des armatures traversant le corps de sorte à être saillantes de part et d'autre. Après coulage de la dalle de compression pour former le plancher, les armatures dépassant vers l'intérieur du bâtiment se trouvent enrobées de sorte qu'elles sont rigidement solidarisées au plancher. Les armatures dépassant de l'autre côté du corps thermiquement isolant sont alors à leur tour noyées dans un élément de béton externe poursuivant la construction du mur. De la sorte, le plancher et le mur se trouvent liés rigidement et les corps thermiquement isolant agencés entre eux limitent les ponts thermiques correspondants. De tels corps thermiquement isolant sont par exemple décrits dans le brevet EP 0 866 185 .In an attempt to treat this type of thermal bridge wall / floor, it is known to arrange thermally insulating body between the wall and the floor, each body having frames passing through the body so as to be protruding from both sides. After pouring the compression slab to form the floor, the reinforcements protruding into the building are located coated so that they are rigidly secured to the floor. The reinforcements protruding from the other side of the thermally insulating body are then 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 the patent EP 0 866 185 .

Toutefois le transport de tels corps thermiquement isolant du site de production jusqu'au chantier du bâtiment concerné ainsi que la mise en place desdits corps sur le chantier peut s'avérer fastidieux du fait de leur volume important.However the transport of such thermally insulating body from the production site to the building site concerned and the establishment of said body on the site can be tedious because of their large volume.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Le but de l'invention est de proposer un procédé de traitement de ponts thermiques entre un plancher et un mur adjacent au plancher qui puisse être mis en oeuvre facilement.The object of the invention is to provide a method for treating thermal bridges between a floor and a wall adjacent to the floor that can be implemented easily.

  • in the vicinity of a portion of the wall, substantially at the level where a floor compression slab is to be poured, thermal insulation elements and structural connection elements of the floor in order to alternately arrange a thermal insulation element and a structural connecting element 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 es of the reinforcements of said structural connecting element is positioned above the portion of the wall and a second portion of said reinforcements is positioned at the level of the future compression slab,
  • pouring concrete to extend the portion of the wall so that the first portion of the reinforcements is embedded in the concrete of the wall extension and pouring the concrete to form the compression slab of the floor so that the rest of said reinforcement, including the second portion of the frames, is found drowned in the concrete floor.

Après coulage de la dalle de compression pour former le plancher, les armatures se trouvent enrobées dans la dalle de compression de sorte qu'elles sont rigidement solidarisées au plancher. En outre, au niveau de leur première portion, les armatures se trouvent également enrobées dans un élément de béton externe poursuivant la construction du mur. De la sorte, le plancher et le mur se trouvent liés rigidement et les éléments d'isolation thermique agencés entre eux limitent les ponts thermiques correspondants.After pouring the compression slab to form the floor, the reinforcements are embedded in the compression slab so that they are rigidly secured 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.

L'invention permet ainsi d'alterner les zones de liaison rigides entre le plancher et le mur avec les zones d'isolation thermique. Les armatures se retrouvent donc concentrées entre les éléments d'isolation thermique, au niveau des éléments de liaison structurelle, de sorte que les éléments d'isolation thermique n'ont pas besoin de remplir de fonction d'ancrage du plancher au mur. De la sorte, les différents éléments d'isolation sont exempts d'armatures ce qui simplifie leur manutention et leur manipulation. En outre, comme les éléments d'isolation thermique et les éléments de liaison structurelle n'ont besoin de remplir chacun qu'une seule fonction, ils s'avèrent de tailles réduites ce qui facilite encore davantage leur manutention et leur manipulation.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 thus concentrated between the thermal insulation elements at the level of the structural connection elements, so that the thermal insulation elements do not need to perform an anchoring function from the floor to the wall. In this way, the various insulation elements are free of reinforcements which simplifies 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 reduced in size which further facilitates their handling and handling.

Un opérateur peut ainsi facilement et rapidement venir positionner les uns à la suite des autres les éléments d'isolation thermique et les éléments de liaison structurelle le long de la portion du mur avant de couler le béton pour lier rigidement le plancher et le mur.An operator can thus easily and quickly come to position one after the other the thermal insulation elements and the structural connection elements along the portion of the wall before pouring concrete to rigidly bind the floor and the wall.

Le procédé selon l'invention s'avère donc simple et rapide à être mis en oeuvre.The method according to the invention is therefore simple and quick to implement.

L'invention concerne également un élément d'isolation thermique pour la mise en oeuvre du procédé de traitement de ponts thermiques qui vient d'être décrit et dans lequel une portion inférieure du bloc en matériau isolant thermiquement comporte une patte qui forme une extension longitudinale de ladite portion inférieure et qui est destinée à recevoir l'élément de liaison structurelle.The invention also relates to a thermal insulation element for carrying out 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.

Grâce à la forme particulière de l'élément d'isolation thermique, l'élément de liaison structurelle peut être simplement posé sur la patte ce qui facilite sa mise en place le long de la portion du mur. Ceci favorise encore davantage la mise en oeuvre du procédé de l'invention.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 favors the implementation of the method of the invention.

En outre, la patte assure un meilleur traitement des ponts thermiques en étant agencée entre le mur et le plancher au niveau d'une zone de liaison rigide entre le plancher et le mur. Une telle patte permet d'assurer une continuité de l'isolation thermique en partie basse du plancher entre deux éléments d'isolation thermique séparés par l'élément de liaison structurelle reposant sur ladite patte.In addition, the tab provides better treatment of thermal bridges by being arranged between the wall and the floor at a rigid connection zone 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.

Selon un mode de réalisation particulier, l'élément d'isolation thermique comporte au moins un bac de réception portant les moyens d'encliquetage de l'élément d'isolation thermique, le bloc en matériau isolant thermiquement étant agencé dans ledit bac de réception.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.

Selon un mode de réalisation particulier, une portion inférieure du bloc en matériau isolant thermiquement de l'élément d'isolation thermique comporte une patte formant une extension longitudinale du bloc, l'élément de liaison structurelle étant alors posé sur ou au-dessus de ladite patte pour être agencé le long du mur.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 then being placed on or above said paw to be arranged along the wall.

L'invention concerne également un élément de liaison structurelle pour la mise en oeuvre du procédé de traitement de ponts thermiques qui vient d'être décrit, l'élément de liaison structurelle comportant un bloc en béton, les armatures étant ancrées dans le bloc en béton de sorte à traverser ledit bloc pour que la première portion et la deuxième portion des armatures soient saillantes de part et d'autre du bloc.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 connection element comprising a concrete block, the reinforcements being anchored in the concrete block. so as to pass through said block so that the first portion and the second portion of the reinforcements are protruding on both sides of the block.

Ainsi, l'élément de liaison structurelle peut être plus simplement posé entre deux éléments d'isolation thermique grâce à la présence du bloc en béton. Ceci favorise encore davantage la mise en oeuvre du procédé de l'invention.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 favors the implementation of the method of the invention.

L'invention concerne également une prédalle destinée à supporter le béton d'une dalle de compression pour constituer conjointement avec cette dalle de compression un plancher, la prédalle comportant un corps en béton et au moins un élément d'isolation thermique tel que précédemment cité solidarisé à un bord de ladite prédalle.The invention also relates to a slab intended to support the concrete of a compression slab to constitute jointly with this slab a floor compression, the slab comprising a concrete body and at least one thermal insulation element as previously cited solidarisé at an edge of said predalle.

Pour toute la présente demande, les termes « inférieur », « supérieur », « hauteur », « longueur » ... doivent être entendus par rapport à la position du plancher et de la portion de mur correspondant une fois qu'ils sont montés.For all the present application, the terms "lower", "upper", "height", "length" ... must be understood in relation to the position of the floor and the corresponding wall portion once they are mounted .

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 à 6, le procédé selon une première mise en oeuvre de l'invention vise ici à traiter les ponts thermiques entre un plancher 1 et un mur 2 adjacent à l'une des rives non porteuse dudit plancher.With reference to Figures 1 to 6 , the method according to a first implementation of the invention aims here to treat the thermal bridges between a floor 1 and a wall 2 adjacent to one of the non-bearing banks of said floor.

Le procédé est mis en oeuvre au cours de la construction du bâtiment.The process is implemented during construction of the building.

A cet effet, le mur 2 est monté jusqu'à sensiblement le niveau où le plancher 1 est destiné à être posé. De préférence, la partie supérieure de la portion de mur montée 3 présente un arrêt 4 qui permet une meilleure jonction avec la suite du mur 2 à construire comme nous le verrons par la suite.For this purpose, the wall 2 is mounted to substantially 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 connection with the continuation of the wall 2 to build as we will see later.

Des poutres P, soutenues par un ou plusieurs étais, sont alors positionnées contre la portion montée 3 du mur 2 de sorte à s'étendre à la normale de ladite portion montée 3 afin de servir de support à la construction du plancher 1.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.

Puis des prédalles (dont une seule est référencée 5 ici) sont successivement accolées les unes aux autres sur les poutres P pour délimiter la surface du plancher 1. L'un des bords longitudinaux 8 d'au moins l'une des prédalles 5, formant en partie l'une des rives non porteuse du plancher 1, longe ici la portion 3 du mur 2 considéré. La figure 3 illustre ainsi la portion déjà montée 3 du mur 2 et ladite prédalle 5. La prédalle 5 est montée de sorte que son bord longitudinal 8 s'étende le long de la portion montée 3 du mur 2 mais avec un décalage par rapport à ladite portion 3. Un espace est donc laissé entre la portion 3 et la prédalle 5.Then predalles (of which only one 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 pre-slats 5, forming partly one of the non-bearing shores floor 1, here runs along the portion 3 of the wall 2 considered. The figure 3 thus illustrates the already mounted portion 3 of the wall 2 and said predalle 5. The predalle 5 is mounted so that its longitudinal edge 8 extends along the mounted portion 3 of the wall 2 but with an offset relative to said portion 3 A space is left between the portion 3 and the predalle 5.

En référence à la figure 4, on agence alors le long dudit bord longitudinal 8 de ladite prédalle 5 des éléments d'isolation thermique 6 et des éléments de liaison structurelle 7 du plancher de sorte à agencer en alternance un élément d'isolation thermique 6 et un élément de liaison structurelle 7. On rapporte ainsi à proximité de la portion 3 du mur 2, le long de ladite portion 3 de mur 2, les différents éléments d'isolation thermique 6 et de liaison structurelle 7 sensiblement au niveau où une dalle de compression 9 du plancher 1 doit être coulée. Plus précisément ici, les différents éléments d'isolation thermique 6 et de liaison structurelle 7 sont agencés entre ledit bord longitudinal 8 de la prédalle 5 et la portion 3 du mur 2 au niveau de l'espace qui a été laissé lors de l'étape de montage des prédalles. De façon préférée, les différents éléments d'isolation thermique 6 et de liaison structurelle 7 sont agencés de sorte qu'une de leur face viennent en appui contre le mur 2 (lorsque celui-ci est complétement monté) et la face opposée correspondante viennent en appui contre le bord longitudinale 8 de la prédalle 5.With reference to the figure 4 then, along said longitudinal edge 8 of said pre-slab 5, thermal insulation elements 6 and structural connection elements 7 of the floor are arranged so as to alternately 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 wall portion 3, the different elements of thermal insulation 6 and of structural connection 7 are substantially brought to the level where a compression slab 9 of the floor 1 must to be cast. More specifically here, the various elements of thermal insulation 6 and structural connection 7 are arranged between said longitudinal edge 8 of the predalle 5 and the portion 3 of the wall 2 at the space which was left during the step mounting of the slabs. In a preferred manner, the various elements of thermal insulation 6 and of structural connection 7 are arranged so that one of their face bears against the wall 2 (when it is completely assembled) and the corresponding opposite face come into contact with each other. support against the longitudinal edge 8 of the predalle 5.

De préférence, on rapporte les différents éléments d'isolation thermique 6 et de liaison structurelle 7 de sorte à les accoler les uns aux autres le long de la portion 3 du mur 2. Lesdits éléments d'isolation thermique 6 et de liaison structurelle 7 forment ainsi une frontière entre la prédalle 5 et la portion 3 de mur 2 correspondante.Preferably, the different elements of thermal insulation 6 and of structural connection 7 are brought together so as to join them together along the portion 3 of the wall 2. Said thermal insulation 6 and structural bonding elements 7 form and a boundary between the predalle 5 and the portion 3 of wall 2 corresponding.

Les différents éléments d'isolation thermique 6 et les différents éléments de liaison structurelle 7 sont tous des éléments indépendants les uns des autres ce qui facilite leur manipulation notamment pour les agencer entre le bord longitudinal 8 de la prédalle 5 et la portion 2 de mur 3 déjà construite.The various thermal insulation 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 pre-slab 5 and the wall portion 2. already built.

Tous les éléments de liaison structurelle 7 sont ici identiques entre eux et tous les éléments d'isolation thermique 6 sont ici identiques entre eux. De la sorte, les différents éléments thermique 6 et de liaison structurelle 7 définissent ensemble une frontière entre la prédalle 5 et le mur 2, frontière continue et d'une même hauteur sur tout le long du bord longitudinal 8 de la prédalle 5 et donc sur tout le long du mur correspondant.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 link 7 together define a boundary between the predalle 5 and the wall 2, continuous border and the same height along the longitudinal edge 8 of the predalle 5 and therefore on all along the corresponding wall.

De façon particulière, les différents éléments d'isolation thermique 6 sont solidarisés à la prédalle 5.In particular, the various thermal insulation elements 6 are secured to the pre-slab 5.

De préférence, la prédalle 5 comporte un corps en béton, par exemple en béton précontraint comprenant des câbles de précontrainte orientés longitudinalement et parallèlement les uns aux autres, et une bordure 10 ancrée dans ledit corps en béton de sorte à former un bord dudit corps. Les différents éléments d'isolation thermique 6 sont ici solidarisés à cette bordure 10 par emboîtement afin de dépasser de la face supérieure du corps en béton de la prédalle 5.Preferably, the predalle 5 comprises a concrete body, for example prestressed concrete comprising prestressing cables oriented longitudinally and parallel 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 so as to protrude from the upper face of the concrete body of the floor 5.

En référence à la figure 6, la bordure 10 est rectiligne et s'étend selon une droite X correspondant ici au bord longitudinal 8 de la prédalle 5 formant l'une des rives non porteuse du plancher 1.With reference to the figure 6 , the border 10 is rectilinear and extends along a line X corresponding here to the longitudinal edge 8 of the predalle 5 forming one of the non-load bearing banks of the floor 1.

La bordure 10 comporte de façon préférée une structure alvéolée 11 en matière plastique qui comprend des cellules en relief s'étendant à partir de la structure 11 vers l'extérieur de la bordure en direction du corps de prédalle 5.The border 10 preferably comprises a honeycomb structure 11 of plastics material which comprises raised cells extending from the structure 11 towards the outside of the border in the direction of the pre-slab body 5.

La bordure 10 rectiligne s'avère donc non seulement flexible et souple mais également légère. Ceci facilite la manipulation de la bordure 10 et permet plus facilement de la solidariser au corps en béton de la prédalle 5. En outre, il s'avère possible de découper facilement la bordure 10 rectiligne pour en modifier la longueur selon les besoins de production. Ceci facilite encore une fois la fixation de la bordure 10 rectiligne à la prédalle 5.The rectilinear border 10 thus proves not only flexible and supple but also light. This facilitates the manipulation of the edge 10 and makes it easier to secure it to the concrete body of the slab 5. In addition, it is possible to easily cut the rectilinear edge 10 to modify the length according to the production needs. This again facilitates the fixing of the rectilinear border 10 to the predalle 5.

Les différentes cellules sont ici ouvertes vers l'extérieur de la bordure 10 en direction du corps de la prédalle 5.The different cells are here open towards the outside of the border 10 towards the body of the predalle 5.

La structure 11 est par exemple en polypropylène.The structure 11 is for example polypropylene.

De façon particulière, la structure 11 comporte une première rangée 12 de cellules agencées côte à côte le long de la droite X (une des cellules de la première rangée étant symbolisée en pointillés et désignée par 13). Toutes les cellules de la première rangée 12 sont ici accolées. La structure 11 comporte une deuxième rangée de cellules 14 agencées côte à côte le long de la droite X et accolées deux à deux (une des cellules de la deuxième rangée 14 étant symbolisée en points-tirets et désignée par 15), chaque bloc de deux cellules accolées (un des blocs étant symbolisé en tirets et désigné par 16) étant séparé par un espace 17 du bloc suivant de deux cellules accolées. Grâce aux différents espaces, la structure 11 s'avère particulièrement flexible.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 dashed 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 joined two by two (one of the cells of the second row 14 being symbolized in dot-dashes and designated by 15), each block of two contiguous cells (one of the blocks being symbolized in dashes 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.

La deuxième rangée de cellules 14 s'étend sous la première rangée de cellules 12 de sorte qu'une cellule de la deuxième rangée 14 se trouve dans le prolongement d'une cellule respective de la première rangée 12. La deuxième rangée de cellules 14 s'étend donc parallèlement à la première rangée de cellules 12.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 s therefore extends parallel to the first row of cells 12.

Ici, les cellules de la première rangée 12 sont toutes identiques entre elles et les cellules de la deuxième rangée 14 sont toutes identiques entre elles. De façon particulière, les cellules de la première rangée 12 et les cellules de la deuxième rangée 14 ont une même longueur (dimension prise le long de la droite X) et sensiblement une même largeur (dimension prise le long d'une droite Y perpendiculaire à la droite X et correspondant au relief des cellules). Les cellules de la deuxième rangée 14 ont ici une hauteur supérieure aux cellules de la première rangée 12 (dimension prise le long d'une droite Z perpendiculaire à la droite X et à la droite Y).Here, 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 each other. Of particular way, 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 straight line Y perpendicular to the right 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).

De la sorte, toutes les cellules de la structure 11 s'étendent à partir d'une même face principale de la structure 11. L'autre face principale de la structure 11 s'avère alors exempte de cellules et est donc sensiblement lisse.In this way, all the cells of the structure 11 extend from 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.

La structure 11 comporte par exemple 29 cellules pour la première rangée 12 et 20 cellules pour la deuxième rangée 14.The structure 11 comprises for example 29 cells for the first row 12 and 20 cells for the second row 14.

De préférence, la structure 11 comporte des évidements 18 (dont une partie seulement est référencée) traversant la structure 11 dans sa largeur. Plus précisément ici un évidement 18 traverse la structure 11 au niveau de chacune des cellules de la deuxième rangée 14 et au niveau de chaque espace 17 séparant les blocs de deux cellules accolées. Les évidements 18 sont agencés en partie haute des cellules de la deuxième rangée 14 et des espaces 17 associés, sensiblement au niveau de la frontière entre la première rangée de cellules 12 et la deuxième rangée de cellule 14.Preferably, the structure 11 has recesses 18 (only 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 each of the cells of the second row 14 and at 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 level of the boundary between the first row of cells 12 and the second row of cells 14.

La portion supérieure de la structure 11 comporte des encoches de clipage 19 (dont une partie seulement est référencée) régulièrement réparties sur la longueur de la structure 11 pour l'emboîtement des éléments d'isolation thermique 6 sur la bordure 10. Les encoches de clipage 19 sont identiques. Les encoches de clipage 19 sont ici ménagées à la frontière entre la première rangée de cellules 12 et la deuxième rangée de cellule 14 par une inflexion dans les parois des cellules. A chaque frontière se trouve ici une encoche de clipage 19. Lorsque les éléments d'isolation thermique 6 sont en place sur la bordure 10, ils recouvrent donc la première rangée de cellules 12.The upper portion of the structure 11 comprises clipping notches 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 notches 19 are here formed 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 insulation elements 6 are in place on the edge 10, they thus cover the first row of cells 12.

De façon particulière, chaque encoche de clipage 19 est surmontée d'un bec antisalissure 20 (dont une partie seulement est référencée). Les becs antisalissure 20 sont tous identiques. Les becs antisalissure 20 sont ici ménagés dans les parois de la première rangée de cellules 12 de sorte à former une protubérance venant au-dessus des encoches de clipage 19. Les becs antisalissure 20 sont en outre configurés de sorte à être inclinés en direction de la portion basse de la structure 11.In particular, each clipping notch 19 is surmounted by an anti-fouling nozzle 20 (only part of which is referenced). The 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 protrusion coming above the clipping notches 19. The antifouling nozzles 20 are further configured so as to be inclined towards the low portion of the structure 11.

La portion inférieure de la structure comporte ici des pieds d'ancrage 21. Les pieds 21 sont régulièrement répartis sur la longueur de la structure 11. Les pieds 21 sont identiques. Chaque pied 21 s'étend ici d'une portion inférieure de la structure 11 vers l'extérieur de la bordure 10 vers la portion inférieure du corps de la prédalle 5. Chaque pied 21 s'étend dans le prolongement de l'une des parois communes à deux cellules accolées de la deuxième rangée 14 (soit une paroi de normale la droite X). La structure 1 comporte ici un pied 21 au niveau de chaque bloc de deux cellules accolées. La structure 11 comporte par exemple dix pieds.The lower portion of the structure here comprises anchoring feet 21. The feet 21 are regularly 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 edge 10 towards the lower portion of the body of the predalle 5. Each foot 21 extends in the extension of one of the walls common two contiguous cells of the second row 14 (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.

De façon particulière, la structure 11 comporte deux ailes 22 associées à chaque pied 21. Chaque aile 22 s'étend transversalement au pied 21 associé entre une partie basse du pied 21 à la deuxième rangée de cellule 14. Plus précisément, chaque aile 22 s'étend de la partie basse du pied 21 jusqu'à la paroi extérieure du bloc de deux cellules accolées correspondant audit pied 21, paroi extérieure parallèle à la paroi commune aux deux cellules accolées dudit bloc.In particular, the structure 11 has 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 cell 14. More specifically, each wing 22 s 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 cells contiguous said block.

Ici, la portion inférieure de la structure 11 comporte au moins une languette de positionnement 23 de la bordure 10. Plus précisément, chaque languette de positionnement 23 est agencée de sorte à s'étendre à la normale de la structure 11 vers l'extérieur de la bordure 10 dans le prolongement des cellules, dans le sens de la largeur de la structure 11 (soit donc ici de sorte à s'étendre selon la droite Z en direction du corps de la prédalle 2).Here, the lower portion of the structure 11 comprises at least one positioning tab 23 of the border 10. More specifically, each positioning tab 23 is arranged to extend to the normal of the structure 11 towards the outside of 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).

La structure comporte ici plusieurs languettes de positionnement 23. Par exemple, la structure 11 comporte deux languettes de positionnement 23.The structure here comprises several positioning tabs 23. For example, the structure 11 comprises two positioning tabs 23.

Les languettes de positionnement 23 sont identiques, s'étendent à partir du même niveau de la portion inférieure et sont réparties sur la longueur de la structure 11. Chaque languette de positionnement 23 s'étend ici à partir de la portion inférieure de l'un des espaces 17 séparant deux blocs de cellules accolées.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 the one spaces 17 separating two contiguous cell blocks.

Les deux extrémités longitudinales (selon l'axe X) de la structure 11 comportent respectivement des moyens d'encliquetage mâle 41 et des moyens d'encliquetage femelle 42 par exemple de type tenon/mortaise. De la sorte, il s'avère possible d'emboîter très simplement les uns à la suite des autres plusieurs bordures 10 en encliquetant les moyens d'encliquetage femelle 42 avec les moyens d'encliquetage mâle 41 de deux bordures 10 consécutives.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 fit one after the other several edges very simply by snapping the female latching means 42 with the male latching means 41 of two consecutive edges 10.

De façon particulière, la bordure 10 comporte un aimant (non visible ici) qui est agencé sur la face principale de la structure 11 opposée de celle à partir de laquelle s'étendent les cellules. L'aimant est agencé de sorte à saillir du reste de ladite face principale. Plus précisément ici, l'aimant est agencé en-dessous des différents évidements 18 de la structure 11.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 precisely here, the magnet is arranged below the various recesses 18 of the structure 11.

De préférence, l'aimant se présente sous la forme d'une bande. L'aimant est agencé de sorte à s'étendre selon la droite X. L'aimant permet ainsi de bien couvrir toute la longueur de la structure 11.Preferably, the magnet is in the form of a band. 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.

La bordure 10 qui vient d'être décrite est de façon préférée fabriquée par injection. La bordure 10 s'avère donc simple et rapide à fabriquer.The border 10 which has just been described is preferably manufactured by injection. The border 10 is therefore simple and quick to manufacture.

De façon particulière, la bordure 10 est fabriquée en deux étapes :

  • au cours d'une première étape, l'aimant est rapporté dans un moule d'injection de la structure 11,
  • au cours de la deuxième étape, la structure 11 est formée et l'aimant est simultanément surmoulé sur la structure 11 de sorte que l'aimant et la structure 11 forment un tout-rigide.
In a particular way, the border 10 is manufactured in two steps:
  • during a first step, the magnet is attached to an injection mold of the structure 11,
  • during 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 form an all-rigid.

Typiquement pour fixer la bordure 10 à la prédalle 5, la bordure 10 est installée dans un moule de fabrication du corps de la prédalle 5 en étant positionnée le long de l'une des rives longitudinales de ce moule.Typically to fix the edge 10 to the predalle 5, the edge 10 is installed in a mold for manufacturing the body of the predalle 5 being positioned along one of the longitudinal edges of this mold.

Les pieds 21 viennent alors reposer sur un fond du moule de fabrication. Les pieds 21 permettent à un opérateur de positionner correctement de façon aisée et rapide la bordure 10 dans le moule de fabrication en servant de point de repérage.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.

De même, chaque languette de positionnement 23 est positionnée dans le moule de fabrication de sorte à s'étendre juste sous les câbles de précontrainte agencés dans le moule de fabrication pour être solidarisés au corps de la prédalle 5. Les languettes de positionnement 23 jouent ainsi également le rôle de point de repérage pour l'opérateur.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 predalle 5. The positioning tabs 23 thus play. also the role of locator point for the operator.

Il s'avère donc très simple de positionner la bordure 10 dans le moule de fabrication et de vérifier le bon positionnement de celle-ci en repérant simplement si les câbles de précontrainte sont bien au-dessus des languettes de positionnement 23 et si les pieds 21 reposent bien sur le fond du moule de fabrication.It is therefore very simple to position the border 10 in the manufacturing mold and to verify the correct positioning thereof by simply identifying if the prestressing cables are well above the tabs positioning 23 and if the feet 21 lie well on the bottom of the manufacturing mold.

Le béton est ensuite coulé dans le moule de fabrication pour former le corps de la prédalle 5.The concrete is then poured into the manufacturing mold to form the body of the pre-slab 5.

Les becs antisalissure 20 permettent de protéger les encoches de clipage 19 lors du coulage du corps de la prédalle 5 et notamment du béton qui pourrait accidentellement être projeté vers lesdites encoches de clipage 19. On évite ainsi que du béton ne se fige dans les encoches de clipage 19 ce qui serait préjudiciable pour un emboîtement ultérieur des éléments d'isolation thermique 6 sur ladite bordure 10.The antifouling nozzles 20 make it possible to protect the clipping notches 19 during casting of the body of the slab 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 of clipping 19 which would be detrimental to a subsequent interlocking of the thermal insulation elements 6 on said border 10.

De façon avantageuse, les évidements 18 permettent d'assurer un équilibrage des pressions subies par la bordure 10 lors du coulage du béton. Les évidements 18 sont bien entendu agencés de sorte à se trouver agencés à une hauteur de la structure 11 supérieure à la hauteur du corps de la prédalle 5 afin que du béton ne puisse pénétrer par les évidements 18 entre le moule de fabrication et la bordure 10.Advantageously, the recesses 18 make it possible to ensure a balancing of the pressures experienced by the edge 10 during the pouring of the 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 and the edge 10 .

Par ailleurs, l'aimant permet tout à la fois de positionner la bordure 10 dans le moule de fabrication, au même titre que les pieds 21 ou les languettes de positionnement 23, mais également de maintenir la bordure 10 en position, même pendant le coulage du béton, en la plaquant contre la rive associée.Moreover, the magnet makes it possible both to position the edge 10 in the manufacturing mold, as well as the feet 21 or the positioning tabs 23, but also to maintain the edge 10 in position, even during casting. concrete, by pressing it against the associated shore.

En effet, lorsque la bordure 10 est agencée dans le moule de fabrication, l'aimant permet de bien plaquer la bordure 10 contre la rive en adhérant au moule de fabrication. Ceci évite l'infiltration du béton entre la bordure 10 et le moule de fabrication au niveau de la portion supérieure de la bordure 10 lors du coulage du corps ce qui pourrait gêner un emboîtement ultérieur des éléments d'isolation thermique 6 sur ladite bordure 10.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 manufacturing 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.

De par sa forme allongée, l'aimant permet en outre de bien couvrir toute la longueur de la structure et donc de bien plaquer toute la bordure 10 contre le moule de fabrication.Due to its elongated shape, the magnet allows in addition to well cover the entire length of the structure and therefore to fully press the entire edge 10 against the manufacturing mold.

Bien entendu, la bordure 10 est conformée de sorte à pouvoir épouser la forme du moule de fabrication afin que son plaquage par l'aimant s'avère possible. Dans le cas d'un chanfrein entre le fond du moule et les parois latérales du moule, les pieds 21 sont ainsi inclinés par rapport au reste de la structure 11 pour pouvoir épouser l'inclinaison dudit chanfrein.Of course, the edge 10 is shaped so as 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 rest of the structure 11 to be able to match the inclination of said chamfer.

Une fois que le béton a été coulé et a terminé de prendre, la bordure 10 se retrouve alors rigidement solidarisée au corps de prédalle 5 de sorte à former avec celui-ci un tout-rigide. La prédalle 5 peut alors être retirée du moule de fabrication.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.

De la sorte, on solidarise facilement et rapidement la bordure 10 au corps de la prédalle 5 par surmoulage durant la fabrication dudit corps.In this way, it is easy and fast to secure the edge 10 to the body of the pre-slab 5 by overmolding during the manufacture of said body.

En référence à la figure 3, la bordure 10 est donc rigidement solidarisée au corps en béton de la prédalle 5 en étant ancrée dans celui-ci. La portion inférieure de la bordure 10, correspondant à celle de la structure 11 et s'étendant ici des pieds 21 jusqu'à sensiblement le niveau des évidements 18 sans toutefois atteindre celui-ci, se trouve enrobée dans le béton du corps de prédalle 5.With reference to the figure 3 , the edge 10 is rigidly secured to the concrete body of the floor 5 being anchored therein. The lower portion of the edge 10, corresponding to that of the structure 11 and extending from the feet 21 to substantially the level of the recesses 18 without reaching it, is embedded in the concrete of the pre-slab body 5 .

La bordure 10 est ainsi agencée de sorte que les cellules s'étendent vers l'intérieur de la prédalle 5. Une partie des cellules se retrouvent donc partiellement noyées dans le béton du corps de prédalle 5. La face principale lisse de la bordure 10 forme la surface libre de la prédalle 5 et donc le bord longitudinal 8 de la prédalle 5.The rim 10 is thus arranged so that the cells extend towards the inside of the pre-slab 5. Part of the cells are therefore partially embedded in the concrete of the slab body 5. The smooth main face of the rim 10 forms the free surface of the slab 5 and thus the longitudinal edge 8 of the slab 5.

La portion supérieure de la structure 11, correspondant à celle de la bordure 10, dépasse donc de la face supérieure du corps de prédalle 5. Les éléments d'isolation thermique 6 peuvent alors être emboîtés sur ladite portion supérieure.The upper portion of the structure 11, corresponding to that of the edge 10, therefore protrudes from the face The heat insulating elements 6 can then be nested on said upper portion.

En référence à la figure 1, l'un de ces éléments d'isolation thermique 6 selon la première mise en oeuvre de l'invention va être à présent décrit.With reference to the figure 1 one of these thermal insulation elements 6 according to the first embodiment of the invention will now be described.

L'élément d'isolation thermique 6 comporte un bloc en matériau isolant thermiquement. Ledit bloc est par exemple en laine minérale.The thermal insulation element 6 comprises a block of thermally insulating material. Said block is for example mineral wool.

Une portion inférieure dudit bloc comporte une patte 50 (ou languette) formant une extension longitudinale du bloc. La patte 50 est venue de matière avec le reste du bloc.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 rest of the block.

Le bloc a donc grossièrement une forme de L avec une partie principale 24 de forme sensiblement parallélépipédique et une partie secondaire formée de l'extension longitudinale 50.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 50.

La patte 50 présente donc une hauteur inférieure à la hauteur de la partie principale 24. La patte 50 a une largeur identique à celle de la partie principale 24. La patte 50 a ici une longueur inférieure à la longueur de la partie principale 24. Par exemple, la patte 50 à une longueur comprise entre 20 et 40 centimètres et la partie principale 24 a une longueur comprise entre 70 et 110 centimètres.The tab 50 therefore has a height less than the height of the main part 24. The tab 50 has a width identical to that of the main part 24. The tab 50 here has a length less than the length of the main part 24. By for example, the tab 50 to a length of between 20 and 40 centimeters and the main part 24 has a length of between 70 and 110 centimeters.

La partie principale 24 a une hauteur sensiblement égale ici à la hauteur totale du plancher 1. De la sorte, lorsque l'élément d'isolation thermique 6 est emboîté sur la bordure 10, la face supérieure de l'élément d'isolation thermique 6 est à hauteur sensiblement de la dalle de compression 9 coulée sur la prédalle 5 comme nous le verrons par la suite.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 thermal insulation element 6 is substantially height of the compression slab 9 casting on the predalle 5 as we will see later.

De façon préférée, la patte 50 est configurée de sorte à présenter une hauteur égale à la hauteur du corps de la prédalle 5.Preferably, the tab 50 is configured to have a height equal to the height of the body of the predalle 5.

De préférence, l'élément d'isolation thermique 6 comporte une plaque 25, le bloc en matériau isolant thermiquement étant solidarisé à ladite plaque 25. A cet effet, l'élément d'isolation thermique 6 comporte deux sangles 26 entourant conjointement la partie principale 24 du bloc en matériau isolant thermiquement et la plaque 25 de sorte à fixer ledit bloc à ladite plaque 25.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 part 24 of the thermally insulating material block and the plate 25 so as to fix said block to said plate 25.

La plaque 25 est par exemple en métal. Typiquement la plaque 25 est en acier.The plate 25 is for example metal. Typically the plate 25 is made of steel.

De préférence, la plaque 25 a une forme sensiblement identique à celle du bloc en matériau isolant thermiquement pour épouser les contours dudit bloc lorsqu'ils sont solidarisés ensemble.Preferably, the plate 25 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.

La plaque 25 porte ici des moyens d'encliquetage 27 aptes à coopérer avec des moyens d'encliquetage correspondants (ici les encoches de clipage 19) de la bordure 10 de la prédalle 5 pour l'emboîtement de l'élément d'isolation thermique 6 sur ladite bordure 10. Les moyens d'encliquetage 27 de l'élément d'isolation thermique sont ici visés à la plaque 25. Lesdits moyens d'encliquetage 27 comportent ici deux doigts légèrement élastiquement déformables comprenant chacun une portion d'accroche conformée en Z, un des bords du Z venant s'encliqueter dans deux encoches de clipage 19 successives de la bordure 10 pour solidariser l'élément d'isolation thermique 6 à la prédalle 5.The plate 25 carries here latching means 27 adapted to cooperate with corresponding latching means (here the clipping notches 19) of the edge 10 of the predalle 5 for the interlocking of the thermal insulation element 6 on said rim 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 hook shaped Z-shaped , one of the edges of the Z snap into two successive clipping notches 19 of the edge 10 to secure the thermal insulation element 6 to the predalle 5.

En référence à la figure 2, l'un des éléments de liaison structurelle 7 selon la première mise en oeuvre de l'invention va être à présent décrit.With reference to the figure 2 one of the structural connecting elements 7 according to the first embodiment of the invention will now be described.

L'élément de liaison structurelle 7 comporte ici un bloc 28 en béton comportant des armatures 29 traversant ledit bloc de sorte à être saillantes de part et d'autre du bloc 28.The structural connecting element 7 here comprises a block 28 of concrete comprising reinforcements 29 passing through said block so as to be projecting on either side of the block 28.

Les armatures 29 sont noyées dans le béton du bloc 28 de l'élément de liaison structurelle 7 de sorte que les armatures 29 et ledit bloc 28 forment un tout-rigide. Les armatures 29 sont par exemple en acier. De préférence, le bloc 28 de l'élément de liaison structurelle 7 est configuré pour être posé sur la patte 50 de l'un des éléments d'isolation thermique 6. Ainsi, le bloc 28 de l'élément de liaison structurelle 7 est ici conformé en un parallélépipède rectangle de même largeur et de même longueur que la patte 50 correspondante. Le bloc 28 de l'élément de liaison structurelle 7 a une hauteur telle que la somme de la hauteur du bloc 28 de l'élément de liaison structurelle 7 et de la hauteur de la patte 50 correspond sensiblement à la hauteur de la partie principale 24 du bloc en matériau isolant thermiquement de l'élément d'isolation thermique 6 associé.The reinforcements 29 are embedded in the concrete of the block 28 of the structural connection element 7 so that that the frames 29 and said block 28 form an all-rigid. The frames 29 are for example steel. Preferably, the block 28 of the structural connection element 7 is configured to be placed on the lug 50 of one of the thermal insulation elements 6. Thus, the block 28 of the structural connection element 7 is here shaped into a rectangular parallelepiped of the same width and the same length as the corresponding tab 50. The block 28 of the structural connecting element 7 has a height such that the sum of the height of the block 28 of the structural connecting element 7 and the height of the tab 50 substantially corresponds to the height of the main part 24 the block of thermally insulating material of the associated thermal insulation element 6.

L'élément de liaison structurelle 7 est donc configuré de sorte que la somme de la hauteur du bloc 28 dudit élément de liaison structurelle 7 et de la hauteur de la patte 50 associée est égale a sensiblement la hauteur totale du plancher 1.The structural connection element 7 is thus configured so that the sum of the height of the block 28 of said structural connection element 7 and the height of the associated tab 50 is substantially equal to the total height of the floor 1.

De la sorte, lorsque l'élément de liaison structurelle 7 est posé sur la patte 50 de l'élément d'isolation thermique 6 associé, la face supérieure de l'élément de liaison structurelle 7 est à hauteur sensiblement de la dalle de compression 9 coulée sur la prédalle 5 comme nous le verrons par la suite.In this way, when the structural connecting element 7 is placed on the lug 50 of the associated thermal insulation element 6, the upper face of the structural connecting element 7 is substantially at the height of the compression slab 9 casting on the floor 5 as we will see later.

Les armatures 29 sont quant à elles bien entendu agencées de sorte à être à une hauteur supérieure à celle de la bordure 10 ancrée dans le corps de la prédalle 5, lorsque l'élément de liaison structurelle 7 est posé sur la patte 50, pour s'étendre d'un côté en direction de la prédalle 5 au-dessus de la prédalle 5 et de l'autre côté en direction du mur 2 au-dessus d'au moins une partie de la portion 3 du mur 2 déjà construite.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 pre-slab 5, when the structural connecting element 7 is placed on the flap 50, for extend on one side towards 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 built.

De façon préférée, le béton du bloc 28 de l'élément de liaison structurelle 7 est un béton ayant une conductivité thermique inférieure à 1 watt par mètre-kelvin. Le béton du bloc 28 de l'élément de liaison structurelle 7 présente donc une conductivité thermique réduite. De la sorte, l'élément de liaison structurelle 7 participe également activement au traitement des ponts thermiques pouvant se former entre le mur 2 et le plancher 1.Preferably, the concrete of the block 28 of the structural connecting element 7 is a concrete having a thermal conductivity lower 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.

Ici, le béton du bloc 28 de l'élément de liaison structurelle 7 est un béton à conductivité thermique inférieure à 0.6 watt par mètre-kelvin ce qui renforce encore davantage le traitement des ponts thermiques par l'élément de liaison structurelle 7. Par exemple, on utilise comme béton du béton Thermédia (marque déposée par la société Lafarge).Here, the concrete of the block 28 of the structural connecting element 7 is a concrete with a thermal conductivity lower than 0.6 watts per meter-kelvin which further reinforces the treatment of the thermal bridges by the structural connecting element 7. For example Thermedia concrete is used as concrete (trademark registered by Lafarge).

De la sorte, en référence à la figure 4, lorsque l'opérateur souhaite agencer les éléments d'isolation thermique 6 et les éléments de liaison structurelle 7 le long de la portion 2 du mur 3, il effectue successivement les étapes suivantes :

  • emboîtement d'un élément d'isolation thermique 6 tel que précédemment décrit sur la bordure 10 de la prédalle 5, la patte 50 de l'élément d'isolation thermique définissant alors l'espace séparant les deux parties principales 24 de deux éléments d'isolation thermique consécutifs,
  • dépose d'un élément de liaison structurelle 7 tel que précédemment décrit sur la patte de l'un des éléments d'isolation thermique de sorte que les armatures 29 en saillie d'un côté de l'élément de liaison structurelle 7 soient positionnées au-dessus d'au moins une partie de la portion 2 du mur 3 et que les armatures 29 en saillie de l'autre côté de l'élément de liaison structurelle 7 soient positionnées au-dessus du corps en béton de la prédalle 5.
In this way, with reference to figure 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 50 of the thermal insulation element defining the space between the two main parts 24 of two elements of consecutive thermal insulation,
  • removal of a structural connecting element 7 as previously described on the leg of one of the thermal insulation elements so that the reinforcements 29 projecting from one side of the structural connecting element 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 concrete body of the predalle 5.

On note que contrairement aux éléments d'isolation thermique 6, les éléments de liaison structurelle 7 ne sont pas solidarisés à la prédalle 5 mais seulement posés le long du bord longitudinal 8 de la prédalle 5.We note that unlike the elements 6, the structural connecting elements 7 are not secured to the predalle 5 but only placed along the longitudinal edge 8 of the predalle 5.

Il s'avère donc très simple pour un opérateur d'agencer les différents éléments d'isolation thermique 6 et de liaison structurelle 7 le long du mur 2 tout en s'assurant de leur bon positionnement puisqu'il suffit à l'opérateur d'emboîter un élément d'isolation thermique 6 sur la bordure 10 déjà en place sur la prédalle 5 puis de poser un élément de liaison structurelle 7 sur la patte de l'élément d'isolation thermique 6 déjà en place également.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 fitting a thermal insulation element 6 on the edge 10 already in place on the pre-slab 5 and then placing a structural connecting element 7 on the lug of the thermal insulation element 6 already in place as well.

De façon avantageuse, les éléments d'isolation thermique 6, les éléments de liaison structurelle 7 et la bordure 10 constituent ensemble une portion de coffrage d'une dalle de compression 9 destinée à être coulée sur la prédalle 5. La mise en oeuvre du coffrage de la dalle de compression 9 s'avère très simple grâce à l'invention par simple encliquetage des éléments d'isolation thermique 6 sur la bordure 10 de la prédalle 5. L'accolement des différents blocs entre eux permet d'assurer un bon coffrage de la dalle de compression 9.Advantageously, the thermal insulation elements 6, the structural connection elements 7 and the edge 10 together constitute a formwork portion of a compression slab 9 intended to be cast on the pre-slab 5. The implementation of the formwork of the compression slab 9 is very simple thanks to the invention by simply snapping the thermal insulation elements 6 on the edge 10 of the predalle 5. The joining of the different blocks together ensures a good formwork of the compression slab 9.

Dès lors, en référence à la figure 5, il ne reste plus qu'à former la dalle de compression 9 en coulant du béton sur la prédalle 5 de sorte que les armatures 29 en saillie de l'élément de liaison structurelle 7 s'étendant au-dessus de la prédalle 5 se retrouvent noyées dans le béton. La dalle de compression 9 est coulée de sorte à venir à hauteur des différents éléments de liaison structurelle 7 et d'isolation thermique 6 longeant le mur 2.Therefore, with reference to figure 5 it remains only to form the compression slab 9 by pouring concrete on the pre-slab 5 so that the reinforcements 29 projecting from the structural connecting element 7 extending above the slab 5 meet again embedded in 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.

Du béton est également coulé au-dessus de la portion 3 de mur 2 déjà existante pour continuer la construction du mur 2 de sorte que les armatures 29 en saillie de l'autre côté de l'élément de liaison structurelle 7 (et qui s'étendent au-dessus de la portion 2 du mur 3 déjà construite) se retrouvent également noyées dans le béton.Concrete is also poured over the already existing wall portion 3 to continue the construction of the wall 2 so that the reinforcements 29 project from the other side of the structural connecting member. 7 (and which extend above the portion 2 of the wall 3 already built) are also found embedded in the concrete.

Les armatures 29 se retrouvent ainsi ancrées d'un côté dans le plancher 1 et de l'autre côté dans le mur 2 ce qui assure la portance du plancher 1.The frames 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.

Par ailleurs, les ponts thermiques susceptibles de se former entre le plancher 1 et le mur 2 sont très limités puisque les éléments d'isolation thermique 6 forment une barrière d'isolation thermique entre le plancher 1 et le mur 2 en étant agencés entre le plancher 1 et le mur 2 sur sensiblement toute la hauteur du plancher 1 (comme bien visibles aux figures 4 et 5). De plus, les ponts thermiques sont encore davantage limités par la présence de la patte 50 d'une hauteur sensiblement également à la hauteur de la prédalle 5 participant à la formation d'une barrière d'isolation thermique continue entre le plancher 1 et le mur 2 : toute la portion inférieure du plancher 1 (correspondant sensiblement à la hauteur de la prédalle 5) se retrouve ainsi isolée thermiquement du mur 2. En outre, les ponts thermiques sont encore davantage limités du fait de l'utilisation d'un béton particulier pour les éléments de liaison structurelle 7, béton qui est bien plus isolant thermiquement que les bétons traditionnellement utilisés dans le domaine des bâtiments et qui ont une conductivité thermique d'au moins 2 watt par mètre-kelvin. Les éléments de liaison structurelle 7 participent ainsi également à la formation d'une barrière d'isolation thermique entre le plancher 1 et mur 2.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 1 and the wall 2 being arranged between the floor 1 and the wall 2 on substantially the entire height of the floor 1 (as clearly visible at figures 4 and 5 ). In addition, the thermal bridges are further limited by the presence of the tab 50 of a height substantially also at the height of the predalle 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 (substantially corresponding 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 use of a particular concrete for the structural connecting elements 7, concrete which is much more thermally insulating than 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 wall 2.

Les ponts thermiques susceptibles de se former entre le plancher 1 et le mur 2 s'avèrent donc extrêmement réduits ici sur tout le long du mur 2 considéré et sur toute la hauteur du plancher 1.The thermal bridges that can form between the floor 1 and the wall 2 are therefore extremely reduced here along the entire wall 2 considered and over the entire height of the floor 1.

Par ailleurs, l'accolement des différents éléments de liaison structurelle 7 et d'isolation thermique 6 permet à la fois d'assurer une bonne isolation thermique du plancher 1 au niveau du mur 2 et à la fois d'assurer une bonne portance du plancher 1.Moreover, the joining of the different elements structural link 7 and thermal insulation 6 allows both to ensure good thermal insulation of the floor 1 at the wall 2 and both to ensure good lift of the floor 1.

En outre, l'utilisation de la laine minérale pour les blocs des éléments d'isolation thermique 6 permet, en plus de la fonction d'isolation thermique, de remplir une fonction supplémentaire de protection contre les incendies ainsi qu'une fonction supplémentaire d'isolation acoustique. Il convient de noter que la présence de la patte 50 sur les éléments d'isolation thermique 6 permet d'améliorer ces fonctions de protection incendie et d'isolation acoustique au niveau de la portion inférieure du plancher 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 soundproofing. It should be noted that the presence of the tab 50 on the thermal insulation elements 6 improves these fire protection and sound insulation functions at the lower portion of the floor 1.

De plus, de par le fait que les éléments d'isolation thermique 6 soient solidarisés par emboîtement à la bordure 10 et que les éléments de liaison structurelle 7 soient positionnés sur les pattes 50 des éléments d'isolation thermique 6, il est possible de s'affranchir d'un support de lisse classique de l'art antérieur relativement volumineux. Un simple soutien par poutre de la prédalle 5 suffit ici.In addition, in that the thermal insulation elements 6 are secured by interlocking with the edge 10 and the structural connecting elements 7 are positioned on the lugs 50 of the thermal insulation elements 6, it is possible to to free from a conventional smooth support of the relatively large prior art. A simple beam support of the predalle 5 is sufficient here.

Une première mise en oeuvre non limitative du procédé selon l'invention vient d'être décrite. La figure 7 illustre une première variante de cette première mise en oeuvre.A first non-limiting implementation of the method according to the invention has just been described. The figure 7 illustrates a first variant of this first implementation.

Dans cette variante, les différents éléments d'isolation thermique 6 ne sont cette fois pas pourvus d'une patte. Mis à part l'absence de patte, les différents éléments d'isolation thermique 6 s'avèrent identiques à ceux précédemment décrits.In this variant, the various elements of thermal insulation 6 are not this time provided with a tab. Apart from the absence of tab, the various elements of thermal insulation 6 are identical to those previously described.

Ainsi, l'élément d'isolation thermique 6 comporte un bloc 30 en matériau isolant thermiquement. Ledit bloc 30 est par exemple en laine minérale.Thus, the thermal insulation element 6 comprises a block 30 of thermally insulating material. Said block 30 is for example mineral wool.

Le bloc 30 a donc ici simplement une forme de parallélépipède rectangle.Block 30 thus has here simply a parallelepiped shape rectangle.

Le bloc 30 a une hauteur sensiblement égale ici à la hauteur totale du plancher. De la sorte, lorsque l'élément d'isolation thermique 6 est emboîté sur la bordure 10 ancrée dans la prédalle 5, la face supérieure de l'élément de liaison structurelle 7 est à hauteur sensiblement de la dalle de compression coulée sur la prédalle.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 edge 10 anchored in the predalle 5, the upper face of the structural connecting element 7 is substantially height of the compression slab cast on the predalle.

De préférence, l'élément d'isolation thermique 6 comporte une plaque 31, le bloc 30 en matériau isolant thermiquement étant solidarisé à ladite plaque 31. A cet effet, l'élément d'isolation thermique 6 comporte deux sangles (dont une seule sangle 32 est visible ici) entourant conjointement le bloc 30 en matériau isolant thermiquement et la plaque 31 de sorte à fixer ledit bloc 30 à ladite plaque 31.Preferably, the thermal insulation element 6 comprises a plate 31, the block 30 of thermally insulating material being secured to said plate 31. For this purpose, the thermal insulation element 6 comprises two straps (including 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.

La plaque 31 est par exemple en métal. Typiquement la plaque 31 est en acier.The plate 31 is for example metal. Typically the plate 31 is made of steel.

De préférence, la plaque 31 a une forme sensiblement identique à celle du bloc 30 en matériau isolant thermiquement pour épouser les contours dudit bloc 30 lorsqu'ils sont solidarisés ensemble.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.

La plaque 31 porte ici des moyens d'encliquetage 40 aptes à coopérer avec des moyens d'encliquetage correspondants (ici les encoches 19 de clipage) de la bordure 10 de la prédalle 5 pour l'emboîtement de l'élément d'isolation thermique 6 sur ladite bordure 10. Les moyens d'encliquetage 40 de l'élément d'isolation thermique 6 sont ici visés à la plaque 31. Lesdits moyens d'encliquetage 40 comportent ici deux doigts légèrement élastiquement déformables comprenant chacun une portion d'accroche conformée en Z, un des bords du Z venant s'encliqueter dans deux encoches de clipage 19 successives de la bordure 10 pour solidariser l'élément d'isolation thermique 6 à la prédalle 5.The plate 31 carries here latching means 40 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 thermal insulation element 6 on said rim 10. The ratchet means 40 of the thermal insulating element 6 are here referred to the plate 31. The ratchet means 40 here comprise two slightly elastically deformable fingers, each comprising a gripping portion formed in accordance with FIG. Z, one of the edges of the Z snap into two successive clipping notches 19 of the edge 10 to secure the thermal insulation element 6 to the predalle 5.

Du fait de l'absence de patte sur lesquelles reposer, les éléments de liaison structurelle 7 de la variante décrite sont conformés pour pouvoir être également solidarisés à la prédalle 5. A cet effet, l'élément de liaison structurelle 7 comporte un bloc 33 en béton et des moyens d'encliquetage 43 aptes à coopérer avec des moyens d'encliquetage correspondants (ici les encoches 19 de clipage) de la bordure 10 de la prédalle 5 pour l'emboîtement de l'élément de liaison structurelle 7 sur ladite bordure 10. Les moyens d'encliquetage 43 de l'élément de l'élément de liaison structurelle 7 sont ici visés au bloc 33. Lesdits moyens d'encliquetage 43 comportent ici deux doigts légèrement élastiquement déformables comprenant chacun une portion d'accroche conformée en Z, un des bords du Z venant s'encliqueter dans deux encoches de clipage 19 successives de la bordure 10 pour solidariser l'élément de liaison structurelle 7 à la prédalle 5.Due to the absence of tab on which to rest, the structural connecting elements 7 of the described variant are shaped to be also secured to the pre-slab 5. For this purpose, the structural connecting element 7 comprises a block 33 in concrete and latching means 43 adapted to cooperate with corresponding latching means (here the notches 19 of clipping) of the edge 10 of the predalle 5 for the interlocking of the structural connecting element 7 on said border 10 The latching means 43 of the element of the structural connecting element 7 are here referred to in block 33. Said latching means 43 here comprise two slightly elastically deformable fingers each comprising a fastening portion shaped in Z, 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 predalle 5.

En outre, comme précédemment décrit, le bloc 33 en béton comporte des armatures 34 traversant ledit bloc 33 de sorte à être saillantes de part et d'autre du bloc 33.In addition, as previously described, the concrete block 33 comprises reinforcements 34 passing through said block 33 so as to protrude on either side of the block 33.

Ainsi, le bloc 33 de l'élément de liaison structurelle 7 est ici conformé en un parallélépipède rectangle. Le bloc 33 de l'élément de liaison structurelle 7 a une hauteur sensiblement identique à la hauteur du bloc 30 en matériau isolant thermiquement de l'élément d'isolation thermique 6 associé. L'élément de liaison structurelle 7 est donc configuré de sorte à avoir une hauteur sensiblement identique à la hauteur totale du plancher.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.

De la sorte, lorsque l'élément de liaison structurelle 7 est solidarisé à la bordure 10 de la prédalle 5, entre la bordure 10 et la portion 2 de mur 3, la face supérieure de l'élément de liaison structurelle 7 est à hauteur sensiblement de la dalle de compression coulée sur la prédalle 5. Les armatures 34 sont quant à elles bien entendu agencées de sorte à être à une hauteur supérieure à celle de la bordure 10 ancrée dans le corps de la prédalle 5, lorsque l'élément de liaison structurelle 7 est agencé le long de la bordure 10, pour s'étendre d'un côté en direction de la prédalle 5 au-dessus de la prédalle 5 et de l'autre côté en direction du mur 2 au-dessus d'au moins une partie de la portion 3 du mur 2 déjà construite.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 substantially height of 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 pre-slab 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 built.

Les armatures 34 sont noyées dans le béton du bloc 33 de l'élément de liaison structurelle 7 de sorte que les armatures 34 et ledit bloc 33 forment un tout-rigide. Les armatures 34 sont par exemple en acier, typiquement en acier inoxydable.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 steel, typically stainless steel.

De façon préférée, le béton du bloc 33 de l'élément de liaison structurelle 7 est un béton ayant une conductivité thermique inférieure à 1 watt par mètre-kelvin. Le béton du bloc 33 de l'élément de liaison structurelle 7 présente donc une conductivité thermique réduite.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 7 thus has a reduced thermal conductivity.

Ici, le béton du bloc 33 de l'élément de liaison structurelle 7 est un béton à conductivité thermique inférieure à 0.6 watt par mètre-kelvin ce qui renforce encore davantage le traitement des ponts thermiques par l'élément de liaison structurelle 7.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 reinforces the treatment of the thermal bridges by the structural connecting element 7.

Une deuxième variante de la première mise en oeuvre du procédé selon l'invention va être à présent décrite en relation avec les figures 8 à 12.A second variant of the first implementation of the method according to the invention will now be described in connection with the Figures 8 to 12 .

Les éléments d'isolation thermique 6 sont ici identiques aux éléments d'isolation thermique 6 décrits en liaison avec la première mise en oeuvre du procédé selon l'invention et les figures 1 à 6.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 the Figures 1 to 6 .

Chaque élément d'isolation thermique 6 comporte ainsi un bloc en matériau isolant thermiquement. Ledit bloc est par exemple en laine minérale.Each thermal insulation element 6 thus comprises a block of thermally insulating material. said block is for example mineral wool.

Une portion inférieure dudit bloc comporte une patte 50 (ou languette) formant une extension longitudinale du bloc. La patte 50 est venue de matière avec le reste du bloc.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 rest of the block.

Le bloc a donc grossièrement une forme de L avec une partie principale 51 de forme sensiblement parallélépipédique et une partie secondaire formée de l'extension longitudinale.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.

La patte 50 présente donc une hauteur inférieure à la hauteur de la partie principale 51. La patte 50 a une largeur identique à celle de la partie principale 51. La patte 50 a ici une longueur inférieure à la longueur de la partie principale. Par exemple, la patte 50 à une longueur comprise entre 20 et 40 centimètres et la partie principale 51 a une longueur comprise entre 70 et 110 centimètres.The tab 50 thus has a height less than 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 to a length of between 20 and 40 centimeters and the main portion 51 has a length of between 70 and 110 centimeters.

La partie principale 51 a une hauteur sensiblement égale ici à la hauteur totale du plancher 1. De la sorte, lorsque l'élément d'isolation thermique 6 est emboîté sur la bordure 10, la face supérieure de l'élément d'isolation thermique 6 est à hauteur sensiblement de la dalle de compression 9 coulée sur la prédalle 5.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 fitted on the edge 10, the upper face of the thermal insulation element 6 is substantially at the height of the compression slab 9 casting on the predalle 5.

De façon préférée, la patte 50 est configurée de sorte à présenter une hauteur égale à la hauteur du corps de la prédalle 5.Preferably, the tab 50 is configured to have a height equal to the height of the body of the predalle 5.

De préférence, chaque élément d'isolation thermique 6 comporte une plaque 52, le bloc en matériau isolant thermiquement étant solidarisé à ladite plaque 52. A cet effet, l'élément d'isolation thermique 6 comporte deux sangles 53 entourant conjointement la partie principale 51 du bloc en matériau isolant thermiquement et la plaque 52 de sorte à fixer ledit bloc à ladite plaque.Preferably, each thermal insulation element 6 comprises a plate 52, the block of thermally insulating material being secured to said plate 52. For this purpose, the thermal insulation element 6 comprises two straps 53 jointly surrounding the main part 51 of the thermally insulating material block and the plate 52 so as to fix said block to said plate.

La plaque 52 est par exemple en métal. Typiquement la plaque 52 est en acier.The plate 52 is for example metal. Typically the plate 52 is made of steel.

De préférence, la plaque 52 a une forme sensiblement identique à celle du bloc en matériau isolant thermiquement pour épouser les contours dudit bloc lorsqu'ils sont solidarisés ensemble.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.

La plaque 52 porte ici des moyens d'encliquetage 54 aptes à coopérer avec des moyens d'encliquetage correspondants (ici les encoches de clipage) de la bordure 10 de la prédalle 5 pour l'emboîtement de l'élément d'isolation thermique 6 sur ladite bordure. Les moyens d'encliquetage 54 de l'élément d'isolation thermique sont ici visés à la plaque. Lesdits moyens d'encliquetage comportent ici deux doigts légèrement élastiquement déformables comprenant chacun une portion d'accroche conformée en Z, un des bords du Z venant s'encliqueter dans deux encoches de clipage successives de la bordure 10 pour solidariser l'élément d'isolation thermique 6 à la prédalle 5.The plate 52 here carries ratchet means 54 capable of cooperating with corresponding latching means (here the clipping notches) of the edge 10 of the pre-slab 5 for the engagement of the thermal insulation element 6 on said border. The latching means 54 of the thermal insulation element are here referred to the plate. Said detent means here comprise two slightly elastically deformable fingers each comprising a fastening portion shaped Z, one of the edges of the Z snap into two successive clipping notches of the edge 10 to secure the insulation element thermal 6 to the predalle 5.

Toutefois, dans cette deuxième variante de la première mise en oeuvre l'invention, les différents éléments de liaison structurelle 7 ne comportent pas de bloc en béton.However, in this second variant of the first embodiment of the invention, the various structural connection elements 7 do not comprise a concrete block.

En référence à la figure 9, chaque élément de liaison structurelle 7 comporte des armatures 55. Les armatures 55 sont par exemple en acier.With reference to the figure 9 each structural connecting element 7 comprises reinforcements 55. The reinforcements 55 are made of steel, for example.

De préférence, l'élément de liaison structurelle 7 est configuré pour être posé sur la patte50 de l'un des éléments d'isolation thermique 6.Preferably, the structural connecting element 7 is configured to be placed on the lug 50 of one of the thermal insulation elements 6.

De la sorte, en référence à la figure 10, lorsque l'opérateur souhaite monter le plancher 1, il vient déjà poser les prédalles 5 sur les poutres P de support.In this way, with reference to figure 10 when the operator wishes to assemble the floor 1, he has already laid the floor 5 on the support beams P.

Puis, en référence à la figure 11, l'opérateur agence les éléments d'isolation thermique 6 et les éléments de liaison structurelle 7 le long de la portion du mur en effectuant successivement les étapes suivantes :

  • emboîtement d'un élément d'isolation thermique 6 tel que précédemment décrit sur la bordure 10 de la prédalle 5, la patte 50 de l'élément d'isolation thermique 6 définissant alors l'espace séparant les deux parties principales 51 de deux éléments d'isolation thermique 6 consécutifs,
  • dépose d'un élément de liaison structurelle 7 tel que précédemment décrit sur la patte 50 de l'un des éléments d'isolation thermique 6 de sorte qu'une portion des armatures 55 se trouvent positionnées au-dessus d'au moins une partie de la portion du mur 3 et qu'une autre portion des armatures 55 se retrouvent positionnées au-dessus du corps en béton de la prédalle 5.
Then, with reference to the figure 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 of a thermal insulation element 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 consecutive thermal insulation elements 6,
  • depositing 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 at least a portion of the portion of the wall 3 and another portion of the armatures 55 are positioned above the concrete body of the predalle 5.

En référence à la figure 12, il ne reste plus qu'à former la dalle de compression 9 en coulant du béton sur la prédalle 5 de sorte que la portion des armatures 55 s'étendant au-dessus de la prédalle 5 et entre les éléments d'isolation thermique 6 se retrouve noyée dans le béton. La dalle de compression 9 est coulée de sorte à venir à hauteur des différents éléments d'isolation thermique 6 longeant le mur.With reference to the figure 12 , it remains only to form the compression slab 9 by casting concrete on the pre-slab 5 so that the portion of the reinforcements 55 extending above the slab 5 and between the thermal insulation elements 6 is found drowned in concrete. The compression slab 9 is cast so as to come up to the different thermal insulation elements 6 along the wall.

Du béton est également coulé au-dessus de la portion de mur 3 déjà existante pour continuer la construction du mur 2 de sorte que la portion des armatures 55 qui s'étend au-dessus de la portion du mur 3 déjà construite se retrouve également noyée dans le béton. Les armatures 55 se retrouvent ainsi ancrées d'un côté dans le plancher 1 et de l'autre côté dans le mur 2 ce qui assure la portance du plancher 1.Concrete is also poured over the wall portion 3 already existing to continue the construction of the wall 2 so that the portion of the reinforcements 55 which extends above the portion of the wall 3 already built is also found drowned. in the concrete. The armatures 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.

On note que dans cette deuxième variante, les pattes 50 des éléments d'isolation thermique 6 permettent non seulement de faciliter le positionnement des différents éléments mais également de former un coffrage pour la portion des armatures 55 agencée entre les éléments d'isolation thermique 6. Ceci permet de simplifier la fabrication du plancher 1.Note that in this second variant, the tabs 50 of the thermal insulation elements 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.

La première variante illustrée à la figure 7 en relation avec la première mise en oeuvre est également applicable ici de sorte que la deuxième variante pourra également comprendre des éléments d'isolation thermique 106 ne comprenant pas de patte 50.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 comprising tab 50.

Une deuxième mise en oeuvre du procédé selon l'invention va être présent décrite en référence aux figures 13 à 15. Les éléments en commun avec la première mise en oeuvre conservent la même numérotation augmentée d'une centaine.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 keep the same numbering increased by a hundred.

Contrairement à la première mise en oeuvre dans laquelle le plancher 1 était un plancher à prédalles, le plancher 101 de la deuxième mise en oeuvre est un plancher à dalle pleine.Unlike the first implementation in which the floor 1 was a floor to floor, the floor 101 of the second implementation is a floor with full slab.

Dès lors, le mur 102 est monté jusqu'à sensiblement le niveau où le plancher 101 est destiné à être posé. De préférence, la partie supérieure de la portion de mur déjà montée présente un arrêt qui permet une meilleure jonction avec la suite du mur à construire.Therefore, the wall 102 is mounted to substantially the level where the floor 101 is intended 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.

Un support de lisse pour la construction du plancher 101 est alors positionné contre la portion montée du mur 102.A smooth support for the construction of the floor 101 is then positioned against the mounted portion of the wall 102.

On agence alors le long du mur 102, directement sur le support, des éléments d'isolation thermique 106 et des éléments de liaison structurelle 107 de sorte à agencer en alternance un élément d'isolation thermique 106 et un élément de liaison structurelle 107 le long dudit mur 102. On rapporte ainsi à proximité de la portion du mur 102, le long de ladite portion, les différents éléments d'isolation thermique 106 et de liaison structurelle 107 sensiblement au niveau où une dalle de compression 109 du plancher 101 doit être coulée. De façon préférée, les différents éléments d'isolation thermique 106 et de liaison structurelle 107 sont agencés de sorte à avoir une de leur face en appui contre le mur 102 (lorsque celui-ci est complétement monté).Then, along the wall 102, thermal insulation elements 106 and structural connection elements 107 are arranged directly on the support, so as to alternately arrange a thermal insulation element 106 and a structural connection element 107 along the wall. of said wall 102. Thus, close to the portion of the wall 102, along said portion, the various 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 face bearing against the wall 102 (when the latter is completely assembled).

Chaque élément d'isolation thermique 106 comporte un bloc en matériau isolant thermiquement. Ledit bloc est par exemple en laine minérale.Each thermal insulation element 106 comprises a block of thermally insulating material. Said block is for example mineral wool.

Une portion inférieure dudit bloc comporte une patte 150 (ou languette) formant une extension longitudinale du bloc. La patte 150 est venue de matière avec le reste du bloc.A lower portion of said block comprises a tab 150 (or tongue) forming a longitudinal extension of the block. The tab 150 is integral with the rest of the block.

Le bloc a donc grossièrement une forme de L avec une partie principale 124 de forme sensiblement parallélépipédique et une partie secondaire formée de la patte 150.The block is therefore roughly L-shaped with a main portion 124 of substantially parallelepipedal shape and a secondary portion formed of the tab 150.

La patte 150 présente donc une hauteur inférieure à la hauteur de la partie principale 124. La patte 150 a une largeur identique à celle de la partie principale 124. La patte 150 a ici une longueur inférieure à la longueur de la partie principale 124. Par exemple, la patte 150 à une longueur comprise entre 20 et 40 centimètres et la partie principale 124 a une longueur comprise entre 70 et 110 centimètres.The tab 150 therefore has a height less than the height of the main part 124. The tab 150 has a width identical to that of the main part 124. The tab 150 here has a length less than the length of the main part 124. By for example, the tab 150 has a length of between 20 and 40 centimeters and the main portion 124 has a length of between 70 and 110 centimeters.

La partie principale 124 a une hauteur sensiblement égale ici à la hauteur totale du plancher 101. De la sorte, la face supérieure de l'élément d'isolation thermique 106 est à hauteur sensiblement de la dalle de compression 109 coulée.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 thermal insulation element 106 is substantially height of the compression slab 109 cast.

On note que contrairement à la première mise en oeuvre et à sa variante, l'élément d'isolation thermique 106 ne comporte ni plaque, ni sangle ni moyens d'encliquetage. Ceci s'explique par le fait que l'élément d'isolation thermique 106 est simplement agencé le long du mur mais n'est pas solidarisé à une quelconque prédalle ou autre partie du bâtiment déjà monté.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.

Par ailleurs, chaque élément de liaison structurelle 107 comporte ici un bloc 128 en béton comportant des armatures 129 traversant ledit bloc 128 de sorte à être saillantes de part et d'autre du bloc 128.Furthermore, each structural connection element 107 here comprises a concrete block 128 comprising reinforcements 129 passing through said block 128 so as to be prominent on both sides of block 128.

Les armatures 129 sont noyées dans le béton du bloc 128 de l'élément de liaison structurelle 107 de sorte que les armatures 129 et ledit bloc 128 forment un tout-rigide. Les armatures 129 sont par exemple en acier, typiquement en acier inoxydable.The armatures 129 are embedded in the concrete of the block 128 of the structural connecting element 107 so that the armatures 129 and said block 128 form an all-rigid. The armatures 129 are for example steel, typically stainless steel.

De préférence, le bloc 128 de l'élément de liaison structurelle 107 est configuré pour être posé sur la patte 150 de l'un des éléments d'isolation thermique 106. Ainsi, le bloc 128 de l'élément de liaison structurelle 107 est ici conformé en un parallélépipède rectangle de même largeur et de même longueur que la patte 150 correspondante. Le bloc 128 de l'élément de liaison structurelle 107 a une hauteur telle que la somme de la hauteur du bloc 128 de l'élément de liaison structurelle 107 et de la hauteur de la patte 150 correspond sensiblement à la hauteur de la partie principale 124 du bloc en matériau isolant thermiquement de l'élément d'isolation thermique 106 associé.Preferably, the block 128 of the structural connection element 107 is configured to be placed on the lug 150 of one of the thermal insulation elements 106. Thus, the block 128 of the structural connection element 107 is here shaped as a rectangular parallelepiped of the same width and length as the corresponding lug 150. 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 tab 150 substantially corresponds to the height of the main portion 124 the block of thermally insulating material of the associated thermal insulation element 106.

L'élément de liaison structurelle 107 est donc configuré de sorte que la somme de la hauteur du bloc 128 dudit élément de liaison structurelle 107 et de la hauteur de la patte 150 est égale a sensiblement la hauteur totale du plancher 101.The structural link member 107 is thus configured such that the sum of the height of the block 128 of said structural link member 107 and the height of the tab 150 is substantially equal to the total height of the floor 101.

De la sorte, lorsque l'élément de liaison structurelle 107 est posé sur la patte 150 de l'élément d'isolation thermique 106 associé, la face supérieure de l'élément de liaison structurelle 107 est à hauteur sensiblement de la dalle de compression 109 coulée.In this way, when the structural connecting element 107 is placed on the lug 150 of the associated thermal insulation element 106, the upper face of the structural connecting element 107 is substantially at the height of the compression slab 109 casting.

De façon préférée, le béton du bloc 128 de l'élément de liaison structurelle 107 est un béton ayant une conductivité thermique inférieure à 1 watt par mètre-kelvin. Le béton du bloc 128 de l'élément de liaison structurelle 107 présente donc une conductivité thermique réduite.In a preferred manner, the concrete of the block 128 of the structural connecting element 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 element 107 thus has a reduced thermal conductivity.

Ici, le béton du bloc 128 de l'élément de liaison structurelle 107 est un béton à conductivité thermique inférieure à 0.6 watt par mètre-kelvin ce qui renforce encore davantage le traitement des ponts thermiques par l'élément de liaison structurelle 107.Here, the concrete of the block 128 of the structural connecting element 107 is a concrete with a thermal conductivity less than 0.6 watts per meter-Kelvin which further reinforces the treatment of the thermal bridges by the structural connection element 107.

De la sorte, lorsque l'opérateur souhaite agencer les éléments d'isolation thermique 106 et les éléments de liaison structurelle 107 le long de la portion 3 du mur 2, il effectue successivement les étapes suivantes :

  • dépose d'un élément d'isolation thermique 106 tel que précédemment décrit le long du mur 2, la patte 150 de l'élément d'isolation thermique définissant alors l'espace séparant les deux parties principales 124 de deux éléments d'isolation thermique consécutifs,
  • dépose d'un élément de liaison structurelle 107 tel que précédemment décrit sur la patte 150 de l'un des éléments d'isolation thermique 106 de sorte que les armatures 129 en saillie d'un côté des éléments de liaison structurelle 107 sont positionnées au-dessus de la portion 2 du mur 3 et les armatures 129 en saillie de l'autre côté des éléments de liaison structurelle 107 sont positionnées au-dessus du support.
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 a thermal insulation element 106 as previously described along the wall 2, the tab 150 of the thermal insulation element defining the space between the two main parts 124 of two consecutive thermal insulation elements ,
  • depositing a structural connecting element 107 as previously described on the tab 150 of one of the thermal insulation elements 106 so that the armatures 129 projecting from one side of the structural connecting elements 107 are positioned above the portion 2 of the wall 3 and the armatures 129 projecting from the other side of the structural connecting elements 107 are positioned above the support.

Dès lors, il ne reste plus qu'à former la dalle de compression 109 en coulant du béton de sorte que les armatures 129 en saillie de l'élément de liaison structurelle 107 s'étendant au-dessus du support se retrouvent noyées dans le béton. La dalle de compression 109 est coulée de sorte à venir à hauteur des différents éléments de liaison structurelle 107 et d'isolation thermique 106 longeant le mur 102.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 along the wall 102.

Du béton est également coulé au-dessus de la portion de mur 103 déjà existante pour continuer la construction du mur 102 de sorte que les armatures en saillie 129 de l'autre côté de l'élément de liaison structurelle 107 (et qui s'étendent au-dessus du mur 102) se retrouvent également noyées dans le béton.Concrete is also poured over the existing wall portion 103 to continue construction of the wall 102 so that the protruding reinforcement 129 on the other side of the structural link member 107 (and extending above the wall 102) are found also embedded in concrete.

Les armatures 129 se retrouvent ainsi ancrées d'un côté dans le plancher 101 et de l'autre côté dans le mur 102 ce qui assure la portance du plancher 101.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.

Par ailleurs, les ponts thermiques susceptibles de se former entre le plancher 101 et le mur 102 sont très limités puisque les éléments d'isolation thermique 106 forment une barrière d'isolation thermique entre le plancher 101 et le mur 102 en étant agencés entre le plancher 101 et le mur 102 sur sensiblement toute la hauteur du plancher 101. De plus, les ponts thermiques sont encore davantage limités par la présence de la patte 150 participant à la formation d'une barrière d'isolation thermique continue entre le plancher 101 et le mur 102: toute la portion inférieure du plancher 101 se retrouve ainsi isolée thermiquement du mur 102. En outre, les ponts thermiques sont encore davantage limités du fait de l'utilisation d'un béton particulier pour les éléments de liaison structurelle 107, béton qui est bien plus isolant thermiquement que les bétons traditionnellement utilisés dans le domaine des bâtiments et qui ont une conductivité thermique d'au moins 2 watt par mètre-kelvin. Les éléments de liaison structurelle 107 participent ainsi également à la formation d'une barrière d'isolation thermique entre le plancher 101 et mur 102.Furthermore, 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 the 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 150 involved in the formation of a continuous thermal insulation barrier between the floor 101 and the floor. wall 102: the entire lower portion of the floor 101 is thus thermally insulated from the wall 102. In addition, the thermal bridges are further limited by the use of a particular concrete for the structural connection elements 107, concrete which is much more thermally insulating than concretes traditionally used in the field of buildings and which have a thermal conductivity of at least 2 watts per m be-kelvin. The structural connection elements 107 thus also participate in the formation of a thermal insulation barrier between the floor 101 and wall 102.

Les ponts thermiques susceptibles de se former entre le plancher 101 et le mur 102 s'avèrent donc extrêmement réduits ici sur tout le long du mur 102 considéré et sur toute la hauteur du plancher 101.The thermal bridges that can form between the floor 101 and the wall 102 are thus extremely reduced here along the entire wall 102 considered and over the entire height of the floor 101.

Par ailleurs, l'accolement des différents éléments de liaison structurelle 107 et d'isolation thermique 106 permet à la fois d'assurer une bonne isolation thermique du plancher 101 au niveau du mur 102 et à la fois d'assurer une bonne portance du plancher 101.Furthermore, the joining of the various structural connection elements 107 and thermal insulation 106 allows both to ensure good thermal insulation of the floor 101 at the wall 102 and both to ensure good lift of the floor 101.

En outre, l'utilisation de la laine minérale pour les blocs des éléments d'isolation thermique 106 permet, en plus de la fonction d'isolation thermique, de remplir une fonction supplémentaire de protection contre les incendies ainsi qu'une fonction supplémentaire d'isolation acoustique. Il convient de noter que la présence de la patte 150 sur les éléments d'isolation thermique permet d'améliorer ces fonctions de protection incendie et d'isolation acoustique au niveau de la portion inférieure du plancher 101.In addition, the use of mineral wool for the blocks of the thermal insulation elements 106, in addition to the thermal insulation function, perform an additional function of fire protection and an additional function of sound insulation. It should be noted that the presence of the tab 150 on the thermal insulation elements makes it possible to improve these fire protection and acoustic insulation functions at the level of the lower portion of the floor 101.

Une deuxième mise en oeuvre non limitative du procédé selon l'invention vient d'être décrite. La première variante illustrée à la figure 7 en relation avec la première mise en oeuvre est également applicable ici de sorte que la deuxième mise en oeuvre pourra également comprendre des éléments d'isolation thermique 106 ne comprenant pas de patte. De même la deuxième variante illustrée aux figures 8 à 12 en relation avec la première mise en oeuvre est également applicable ici de sorte que la deuxième mise en oeuvre pourra également comprendre des éléments de liaison structurelle 107 ne comportant pas de bloc de béton.A second nonlimiting implementation of the method according to the invention has just been described. The first variant illustrated in figure 7 in connection with the first implementation is also applicable here so that the second implementation may also include thermal insulation elements 106 not comprising tab. Similarly, the second variant illustrated in Figures 8 to 12 in connection with the first implementation is also applicable here so that the second implementation may also include structural connecting elements 107 not comprising a concrete block.

Une troisième mise en oeuvre du procédé selon l'invention va être présent décrite en référence à la figure 16. Les éléments en commun avec la première mise en oeuvre conservent la même numérotation augmentée de deux centaines.A third implementation of the method according to the invention will be present described with reference to the figure 16 . The elements in common with the first implementation keep the same numbering increased by two hundred.

Contrairement à la première mise en oeuvre, bien que le plancher 201 soit également un plancher à prédalles, les différents éléments d'isolation thermique 206 ne sont pas ici solidarisés à la prédalle 205 par encliquetage mais en étant directement ancrés dans le corps en béton de ladite prédalle 205. On note ainsi que la prédalle 205 ne comporte aucune bordure et que les éléments d'isolation thermique 206 ne comportent aucuns moyens d'encliquetage comme dans la première mise en oeuvre.Unlike the first implementation, although the floor 201 is also a floor to floor, the various thermal insulation elements 206 are not here secured to the predalle 205 by snapping but being directly anchored in the concrete body of said predalle 205. It is noted that the prealle 205 has no border and that the thermal insulation elements 206 have no latching means as in the first implementation.

Les éléments d'isolation thermique 206 sont ainsi solidarisés à la prédalle 205 au cours même de la fabrication de la prédalle 205. A cet effet, on agence les éléments d'isolation thermique 206 dans le moule de fabrication de la prédalle 205 de sorte qu'ils se trouvent accolés à la rive dudit moule. Puis on coule le corps en béton de la prédalle 205 ce qui permet d'ancrer les éléments d'isolation thermique 206 dans ledit corps en béton et ainsi de solidariser les éléments d'isolation thermique 206 à la prédalle 205.The thermal insulation elements 206 are thus secured to the predalle 205 during the manufacture of the pre-slab 205. For this purpose, the thermal insulation elements 206 are arranged in the pre-slab production mold 205 so that they are contiguous to the bank of said mold. Then poured the concrete body of the predalle 205 which allows to anchor the thermal insulation elements 206 in said concrete body and thus to secure the thermal insulation elements 206 to the predalle 205.

Les éléments d'isolation thermique 206 se trouvent ainsi au bord de la prédalle 205 et non décalés du bord de la prédalle 205.The thermal insulation elements 206 are thus at the edge of the predalle 205 and not offset from the edge of the predalle 205.

Pour le reste, les éléments d'isolation thermique 206 et les éléments de liaison structurelle 207 sont ici identiques à ceux de la première mise en oeuvre et les éléments de liaison structurelle 207 sont rapportés le long du mur en étant posés sur la patte 250 de l'élément d'isolation thermique adjacent.For the rest, the thermal insulation elements 206 and the structural connecting elements 207 are here identical to those of the first implementation and the structural connecting elements 207 are attached along the wall by being placed on the tab 250 of the adjacent thermal insulation element.

Une quatrième mise en oeuvre du procédé selon l'invention va être présent décrite en référence à la figure 17. Les éléments en commun avec la première mise en oeuvre conservent la même numérotation augmentée de trois centaines.A fourth implementation of the method according to the invention will be present described with reference to the figure 17 . The elements in common with the first implementation keep the same numbering increased by three hundred.

Contrairement à la première mise en oeuvre, bien que le plancher 301 soit également un plancher à prédalles, les différents éléments d'isolation thermique 306 ne sont pas ici solidarisés à la prédalle 305 par encliquetage mais en étant directement ancrés dans le corps en béton de ladite prédalle 305. On note ainsi que la prédalle 305 ne comporte aucune bordure et que les éléments d'isolation thermique 306 ne comportent aucuns moyens d'encliquetage comme dans la première mise en oeuvre.Unlike the first implementation, although the floor 301 is also a floor to floor, the various thermal insulation elements 306 are not here secured to the predalle 305 snap but being directly anchored in the concrete body of said predalle 305. It is noted that the predalle 305 has no border and that the thermal insulation elements 306 have no latching means as in the first implementation.

Les éléments d'isolation thermique 306 sont ainsi solidarisés à la prédalle 305 au cours même de la fabrication de la prédalle 305. A cet effet, on agence les éléments d'isolation thermique 306 dans le moule de fabrication de la prédalle 305 de sorte qu'ils se trouvent accolés à la rive dudit moule. Puis on coule le corps en béton de la prédalle 305 ce qui permet d'ancrer les éléments d'isolation thermique 306 dans ledit corps en béton et ainsi de solidariser les éléments d'isolation thermique 206 à la prédalle 305.The thermal insulation elements 306 are thus secured to the floor plate 305 during manufacture. of the predalle 305. For this purpose, the thermal insulation elements 306 are arranged in the manufacturing mold of the pre-plate 305 so that they are contiguous to the edge of said mold. Then poured the concrete body of the predalle 305 which allows to anchor the thermal insulation elements 306 in said concrete body and thus to secure the thermal insulation elements 206 to the predalle 305.

Les éléments d'isolation thermique 306 se trouvent ainsi au bord de la prédalle 305 et non décalés du bord de la prédalle 305.The thermal insulation elements 306 are thus at the edge of the predalle 305 and not offset from the edge of the predalle 305.

Pour le reste, les éléments d'isolation thermique 306 et les éléments de liaison structurelle 307 sont ici identiques à ceux de la deuxième variante de la première mise en oeuvre et les éléments de liaison structurelle 307 sont rapportés le long du mur en étant posés sur la patte 350 de l'élément d'isolation thermique adjacent, les différents éléments de liaison structurelle 307 ne comportant toutefois pas de bloc en béton.For the rest, the thermal insulation elements 306 and the structural connection elements 307 are here identical to those of the second variant of the first implementation and the structural connection elements 307 are attached along the wall by being placed on the tab 350 of the adjacent thermal insulation element, the various structural connecting elements 307, however, not comprising a concrete block.

Bien entendu l'invention n'est pas limitée aux mises en oeuvre décrites et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Naturally, the invention is not limited to the implementations described and variant embodiments can be provided without departing from the scope of the invention as defined by the claims.

Bien qu'ici les différents éléments soient solidarisés à la prédalle une fois la prédalle en place contre le mur, les différents éléments pourront être solidarisés à la prédalle avant la pose de la prédalle contre le mur (par exemple directement sur le site de production de la prédalle ou alors sur le site de fabrication du bâtiment avant montage de la prédalle).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 against the wall (eg directly on the production site of the pre-slab or at the manufacturing site of the building before mounting the slab).

Bien qu'ici la prédalle ne comporte qu'une seule bordure, la prédalle pourra comporter un plus grand nombre de bordures pour former l'un de ses bords. Les bordures successives destinées à former un bord de la prédalle pourront soit être emboîtées les unes aux autres au niveau de leurs extrémités, soit être accolées les unes aux autres sans être emboîtées soit être séparées par un espace.Although here the predalle has only one border, the predalle may have a greater number of borders to form one of its edges. The successive edges intended to form an edge of the predalle may be nested to each other at their ends, or be contiguous to each other without being nested or separated by a space.

Les bordures pourront être redécoupées à une longueur voulue pour former le bord de la prédalle de sorte que l'extrémité découpée ne comporte aucun moyen d'encliquetage contrairement à l'extrémité formée initiale, qu'une des cellules ne soit pas complète après découpage ...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 initial formed end, one of the cells is not complete after cutting. ..

La bordure pourra être différente de ce qui a été décrite. La deuxième rangée de cellules pourra ainsi ne comporter que des cellules accolées les unes aux autres. La première rangée de cellules et la deuxième rangée de cellules comporteront alors le même nombre de cellules. Les languettes s'étendront alors sous l'une des cellules de la deuxième rangée, cellule non associée à un pied d'ancrage.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.

En variante, la bordure pourra ne pas comporter de pieds, de languette ... Les cellules, les pieds, les languettes, les becs antisalissure, les encoches de clipage pourront ne pas tous être identiques. La bordure pourra comporter un nombre différent de rangées de cellules. Les cellules ne seront pas nécessairement organisées en rangée.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.

La bordure pourra ne pas comporter d'aimant. Dans ce cas, la bordure pourra être simplement posée dans le moule de fabrication du corps de prédalle en étant positionnée le long des rives de ce moule et en étant le cas échéant simplement maintenue en position par des organes de maintien externes.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 banks of this mold and possibly being simply held in position by external holding members.

Bien qu'ici, la bordure soit solidarisée au corps de la prédalle par surmoulage durant la fabrication dudit corps, elle pourra être solidarisée au corps de prédalle différemment par exemple par des éléments de fixation de type vis ou autre.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.

Bien qu'ici la bordure comporte une structure alvéolaire en matière plastique, la bordure pourra être dans un autre matériau par exemple en béton ou encore en métal.Although here the border has a honeycomb structure of plastic material, the border may be in another material, for example concrete or metal.

Chacune des variantes des éléments d'isolation thermique pourront être associées à n'importe laquelle des bordures précitées. De même, chacune des variantes des éléments de liaison structurelle pourront être associées à n'importe laquelle des bordures précitées.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 connection elements may be associated with any of the aforementioned borders.

L'élément d'isolation thermique pourra ainsi être solidarisé à la prédalle autrement que ce qui a été décrit. Par exemple, l'élément d'isolation thermique pourra comporter au moins un bac de réception dans lequel le bloc en matériau isolant thermiquement sera agencé, l'élément d'isolation thermique étant alors solidarisé à la bordure par emboîtement du bac de réception à ladite bordure de sorte que l'élément d'isolation thermique s'étende entre le mur et la bordure.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 to said edge so that the thermal insulation element extends between the wall and the edge.

L'élément d'isolation thermique pourra être solidarisé à la prédalle autrement que par emboîtement à la bordure de prédalle. La prédalle pourra ainsi ne pas comporter de bordure. L'élément d'isolation thermique pourra ainsi être solidarisé à la prédalle par collage, vissage ou encore par ancrage dans le corps de béton de la prédalle comme cela a déjà été indiqué (l'élément d'isolation thermique étant alors solidarisé à la prédalle au cours même de la fabrication de la prédalle) ...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 or anchoring in the concrete body of the predalle as has already been indicated (the thermal insulation element then being secured to the predalle during the manufacture of the predalle) ...

En variante, l'élément d'isolation thermique pourra simplement être agencé entre la prédalle et le mur sans être solidarisé à la prédalle.Alternatively, the thermal insulation element can simply be arranged between the predalle and the wall without being secured to the predalle.

De même, indépendamment du type de plancher considéré, l'élément d'isolation thermique pourra être différent de ce qui a été décrit.Similarly, regardless of the type of floor considered, the thermal insulation element may be different from what has been described.

Ainsi, le bloc de l'élément d'isolation thermique pourra être dans un matériau différent de ce qui a été décrit par exemple à base de polystyrène, à base de polystyrène expansé, à base de laine minérale, à base de perlite expansée ... Bien qu'ici la patte du bloc de l'élément d'isolation thermique soit venue de matière avec le reste dudit bloc, la patte pourra former un élément indépendant du reste du bloc mais fixé au bloc (par vissage, par collage ...) de sorte que la patte et le reste du bloc forment un tout-rigide.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 expanded perlite ... Although here the leg of the block of the thermal insulation element is integral with the rest of said block, the tab may form an independent element of the rest of the block but attached to the block (by screwing, gluing ...) so that the tab and the rest of the block form an all-rigid.

Lorsque l'élément d'isolation thermique comporte une plaque portant les moyens d'encliquetage, ladite plaque pourra ne pas être d'une forme identique à celle du bloc en matériau thermiquement isolant correspondant. La plaque pourra être solidarisée différemment au bloc que par une sangle par exemple par collage ou vissage ou encore à l'aide d'un élastique. L'élément d'isolation thermique pourra ne pas comporter de plaque. Dans ce cas, si l'élément d'isolation thermique comporte des moyens d'encliquetage ou d'emboîtement à la prédalle, les moyens d'encliquetage pourront être directement fixés au bloc de l'élément d'isolation thermique par exemple par collage ou par visage. Le bloc de l'élément d'isolation thermique pourra dans ce cas être à base de perlite expansée.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 corresponding thermally insulating material block. The plate may be secured differently to the block than by a strap for example by gluing or screwing or using an elastic. The thermal insulation element may not include a plate. In this case, if the thermal insulation element comprises means for snap-fitting or engagement 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 may in this case be based on expanded perlite.

En outre, bien qu'ici les différents éléments d'isolation thermique soient tous identiques entre eux le long d'un même mur, les différents éléments d'isolation thermique pourront bien entendu être différents entre eux le long d'un même mur. Par exemple, certains éléments d'isolation thermique pourront comporter une patte comme illustrés à la figure 1 et d'autre ne pas en comporter comme illustrés à la figure 7. Les éléments d'isolation thermique pourront être de dimensions différentes entre eux notamment de longueur différente. Certains éléments d'isolation thermique pourront être formés d'un seul bloc en matériau thermiquement isolant et d'autre de plusieurs blocs en matériau thermiquement isolant solidarisés entre eux. Dans le cas d'un plancher à prédalle, certains éléments pourront être solidarisés à la prédalle et d'autre seulement agencés le long de la prédalle sans y être solidarisé.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 can of course be different from each other along the same wall. For example, some thermal insulation elements may include a leg as shown in FIG. figure 1 and other not to include as illustrated in the figure 7 . The thermal insulation elements may be of different sizes to each other in particular of 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 secured between them. In the case of a floor to prealle, some elements may be secured to the predalle and other only arranged along the predalle without being secured.

De même, indépendamment du type de plancher considéré, l'élément de liaison structurelle pourra être différent de ce qui a été décrit.Similarly, regardless of the type of floor considered, the structural connection element may be different from what has been described.

L'élément de liaison structurelle pourra ne pas être agencé le long du mur en étant posé sur la patte de l'élément d'isolation thermique contigu mais reposer directement sur un support de lisse permettant le montage du plancher (plancher à prédalles ou plancher à dalle pleine) ou être solidarisé à une prédalle (plancher à prédalle). Dans ce dernier cas, l'élément de liaison structurelle pourra être solidarisé à la prédalle par emboîtement à la bordure de la prédalle. A cet effet, l'élément de liaison structurelle pourra comporter des moyens d'encliquetage aptes à coopérer avec des moyens d'encliquetage correspondants de la bordure (comme des encoches de clipage de la bordure) ancrée dans la prédalle. L'élément de liaison structurelle pourra comporter au moins un bac de réception dans lequel le bloc en béton est agencé, l'élément de liaison structurelle étant alors solidarisé à la bordure par emboîtement dudit bac de réception à la bordure. L'élément de liaison structurelle pourra être solidarisé à la prédalle autrement que par emboîtement à la bordure de prédalle. La prédalle pourra ainsi ne pas comporter de bordure. L'élément de liaison structurelle pourra ainsi être solidarisé à la prédalle par collage, vissage, par ancrage dans le corps de béton de la prédalle ... ... En variante, l'élément de liaison structurelle pourra simplement être agencé entre la prédalle et le mur sans être solidarisé à la prédalle.The structural connecting element may not be arranged along the wall by being placed on the leg of the adjacent thermal insulation element but rest directly on a support of a bar for mounting the floor (floor to floor or floor to solid slab) or be secured to a slab (floor to floor). 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 latching means capable of cooperating with corresponding latching means of the edge (such as clipping notches of the edge) anchored in the predalle. 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 said receiving tray at the edge. The structural connecting element may be secured to the predalle other than by interlocking with the predalle edge. The predalle may thus have no border. The structural connection element can thus be secured to the predalle by gluing, screwing, anchoring in the concrete body of the predalle ... In a variant, the structural connecting element can simply be arranged between the predalle and the wall without being secured to the predalle.

Le bloc en béton de l'élément de liaison structurelle pourra être dans un matériau différent de ce qui a été décrit. Par exemple, le béton du bloc de l'élément de liaison structurelle pourra être un béton à très haute performance. Le béton choisi pourra ainsi présenter une résistance à la compression supérieure à 80 MégaPascal.The concrete block of the structural connecting element may be of a material different from that which has has been described. For example, the concrete of the block of the structural connecting element may be a concrete with very high performance. The selected concrete may thus have a compressive strength greater than 80 MegaPascal.

Ceci permettra de renforcer le soutien structurel apporté au plancher et notamment de permettre au bâtiment concerné de respecter les normes sismiques en vigueur. On utilisera par exemple comme béton du béton Ductal (marque déposée par la société Lafarge).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. For example, concrete Ductal (trademark registered by Lafarge) will be used as concrete.

En variante, le béton du bloc de l'élément de liaison structurelle pourra être un béton à haute performance ou encore un béton ultra-haute performance.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.

En outre, bien qu'ici les différents éléments de liaison structurelle soient tous identiques entre eux le long d'un même mur, les différents éléments de liaison structurelle pourront bien entendu être différents entre eux le long d'un même mur. Par exemple, certains éléments de liaison structurelle pourront être agencés sur les pattes des éléments d'isolation thermique et d'autre être agencés directement le long du mur sans reposer sur de telles pattes. Les éléments de liaison structurelle pourront être de dimensions différentes entre eux, notamment être de longueur différente. Dans le cas d'un plancher à prédalles, certains éléments pourront être solidarisés à la prédalle et d'autre seulement agencés le long de la prédalle.In addition, although here the different structural connection elements are all identical to each other along the same wall, the various structural connection elements may of course be different from each other along the same wall. For example, some structural connection elements may be arranged on the legs of the thermal insulation elements and other be arranged directly along the wall without relying on such tabs. The structural connection elements may be of different sizes to each other, in particular be of different length. In the case of a floor with pre-slabs, some elements may be secured to the predalle and others only arranged along the predalle.

De même, indépendamment du type de plancher considéré, bien qu'ici le béton soit d'abord coulé au niveau du plancher avant d'être coulé au niveau du mur, on pourra bien entendu couler d'abord le béton au niveau du mur pour poursuivre la construction du mur avant de couler le béton au niveau du plancher.Similarly, regardless of the type of floor considered, although here the concrete is first poured to the floor before being poured at the wall, we can of course first pour the concrete at the wall to continue the construction of the wall before pouring concrete at floor level.

En outre, bien qu'ici les différents éléments soient accolés les uns aux autres, on pourra agencer les différents éléments de sorte à laisser un léger espace entre deux éléments consécutifs. On pourra également solidariser les différents éléments entre eux une fois qu'ils sont accolés et agencés le long du mur (par collage ou vissage par exemple). Bien qu'ici les différents éléments soient tous indépendants entre eux avant leur montage le long du mur, on pourra envisager de solidariser un ou plusieurs éléments entre eux dans un premier temps et d'agencer ensuite ledit ensemble le long du mur dans un deuxième temps au lieu de les solidariser l'un à l'autre une fois qu'ils sont déjà agencés le long du mur.In addition, although here the different elements are joined to each other, we can arrange the different elements so as to leave a small space between two consecutive elements. We can also secure the various elements together once they are contiguous 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, we can consider joining one or more elements together at first and then arrange the assembly along the wall in a second step instead of securing them to each other once they are already arranged along the wall.

Les éléments de liaison structurelle comme les éléments d'isolation thermique pourront également comporter une couche supplémentaire de protection contre les incendies comme par exemple une couche en laine minérale. En variante, le matériau des blocs des différents éléments de liaison structurelle comme le matériau des éléments d'isolation thermique pourront eux-mêmes assurer une fonction de protection contre les incendies.Structural connection elements such as thermal insulation elements may also include 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.

Bien qu'ici le procédé selon l'invention ait été mis en oeuvre pour le traitement de ponts thermiques entre la rive non porteuse du plancher et le mur adjacent à ladite rive, le procédé pourra également être mis en oeuvre pour le traitement de ponts thermiques entre une rive porteuse du plancher et un mur adjacent à ladite rive.Although here the method according to the invention has been implemented for the treatment of thermal bridges between the non-bearing edge of the floor and the wall adjacent to said bank, the method may also be implemented for the treatment of thermal bridges. between a bearing bank of the floor and a wall adjacent to said bank.

Pour un même bâtiment, on pourra mettre en oeuvre le procédé selon l'invention pour isoler le plancher, au niveau de ses deux rives non porteuses, des murs adjacents et mettre en oeuvre un procédé de l'art antérieur pour isoler le plancher, au niveau de ses deux rives porteuses, des murs adjacents.For the same building, the method according to the invention can be used 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 level of its two supporting banks, adjacent walls.
