Description

Elément préfabriqué pour la construction de bâtiments, permettant la suppression des ponts thermiques  Prefabricated element for the construction of buildings, allowing the removal of thermal bridges
La présente invention se rapporte à un élément préfabriqué pour la construction de bâtiments, à une poutrelle destinée à coopérer avec un tel élément, et à un bâtiment incorporant de tels éléments. The present invention relates to a prefabricated element for the construction of buildings, to a beam intended to cooperate with such an element, and to a building incorporating such elements.
Il est déjà connu d'utiliser des éléments préfabriqués afin de faciliter les constructions des bâtiments. It is already known to use prefabricated elements to facilitate the construction of buildings.
Ces éléments au coût de revient moins important que celui des pièces réalisées sur chantier, permettent un gain financier notable et présentent une certaine simplicité d'utilisation, ce qui permet en conséquence de gagner du temps lors d'une construction. De tels éléments existent pour presque toutes les applications dans les constructions : poutres, poteaux, escaliers... These elements, which cost less than those produced on site, allow a significant financial gain and a certain simplicity of use, which consequently saves time during construction. Such elements exist for almost all applications in buildings: beams, columns, stairs ...
Toutefois, la technique des préfabriqués ne résout qu'imparfaitement la problématique liée aux ponts thermiques, c'est-à-dire aux zones de moindre résistance thermique entre l'extérieur et l'intérieur, situées en particulier à la liaison entre les murs extérieurs et les planchers. However, the prefabricated technique only imperfectly solves the problem related to thermal bridges, that is to say the areas of least thermal resistance between the outside and the inside, located in particular at the connection between the external walls. and the floors.
Ces ponts thermiques sont réellement nuisibles à un bâtiment et leur présence entraîne notamment des pertes énergétiques (typiquement de l'ordre de 5% des pertes de chaleur d'un bâtiment), de l'humidité dans les parois, et une augmentation de corrosion de la structure. These thermal bridges are really harmful to a building and their presence entails in particular energy losses (typically of the order of 5% of heat loss of a building), moisture in the walls, and an increase in corrosion of the building. the structure.
Différentes techniques existent pour supprimer ou réduire ces ponts thermiques inhérents à l'utilisation de préfabriqués, consistant par exemple à insérer des rupteurs thermiques (formés par exemple en polystyrène) dans la zone de raccordement des poutrelles de plancher aux murs extérieurs, à placer une isolation extérieure sur les murs, etc. Various techniques exist to eliminate or reduce these thermal bridges inherent to the use of prefabricated, consisting for example of inserting thermal breakers (formed for example polystyrene) in the connection area of the floor beams to the outer walls, to place an insulation outside on the walls, etc.
Toutes ces solutions existantes nécessitent des interventions spécifiques rendant plus complexes la construction des bâtiments, et amenuisant le bénéfice procuré par l'utilisation d'éléments de construction préfabriqués. All these existing solutions require specific interventions making the construction of buildings more complex, and reducing the benefit provided by the use of prefabricated building elements.
Pour remédier à c e s inconvénients, F R 2 539 165 et DE 20 2006 008 435 proposent chacun u n élément préfabriqué pour la construction d'un bâtiment, comportant une partie structurelle munie d'une première face destinée à être placée du côté extérieur dudit bâtiment, d'une deuxième face destinée à être placée du côté intérieur dudit bâtiment, ledit incorporant, sur au moins une partie de sa deuxième surface, au moins une couche d'au moins un matériau isolant. Avec les solutions proposées par chacun de ces deux documents de l 'état de la techn ique, l'isolation permettant de supprimer les ponts thermiques fait partie de l'élément préfabriqué : il n'est donc plus nécessaire de mettre en place des moyens d'isolation postérieurement à la mise en place de cet élément, ce qui constitue une simplification considérable par rapport aux autres solutions existantes et permet d'obtenir des cadences et de coûts de construction nettement améliorés. To remedy these disadvantages, FR 2 539 165 and DE 2006 008 435 each propose a prefabricated element for the construction of a building, comprising a structural part provided with a first face intended to be placed on the outside of said building, d. a second face intended to be placed on the inside of said building, said incorporating, on at least a portion of its second surface, at least one layer of at least one insulating material. With the solutions proposed by each of these two state-of-the-art documents, the insulation for eliminating thermal bridges is part of the prefabricated element: it is no longer necessary insulation after the implementation of this element, which is a considerable simplification compared to other existing solutions and provides significantly improved rates and construction costs.
La présente invention a notamment pour but de permettre la réalisation de planchers avec réduction - voire suppression - des ponts thermiques entre les éléments préfabriqués susmentionnés et ces planchers. On atteint ce but de l'invention avec un élément préfabriqué pour la construction d'un bâtiment, comportant une partie structurelle munie d'une première face destinée à être placée du côté extérieur dudit bâtiment, d'une deuxième face destinée à être placée du côté intérieur dudit bâtiment, ledit élément incorporant, sur au moins une partie de sa deuxième surface, au moins une couche d'au moins un matériau isolant, ainsi qu'une pluralité d'équerres de support d'éléments formant ossature de plancher. The present invention is intended in particular to allow the realization of floors with reduction - or suppression - thermal bridges between the aforementioned prefabricated elements and these floors. This object of the invention is achieved with a prefabricated element for the construction of a building, comprising a structural part provided with a first face intended to be placed on the outer side of said building, a second face intended to be placed on the outside. interior side of said building, said element incorporating, on at least a portion of its second surface, at least one layer of at least one insulating material, and a plurality of support brackets of floor structure elements.
Ces équerres de support, qui introduisent une discontinuité entre les éléments préfabriqués et les éléments formant ossature de plancher, contribuent à la rupture des ponts thermiques entre l'extérieur et l'intérieur des bâtiments. These support brackets, which introduce a discontinuity between the prefabricated elements and the elements forming the floor structure, contribute to breaking thermal bridges between the outside and the inside of buildings.
A noter que les « éléments formant ossature de plancher » peuvent être des poutrelles entre lesquelles sont destinés à être placés des hourdis ou entrevous, ou bien des pré-dalles, l'ensemble étant ensuite destiné à être noyé dans le béton (si nécessaire avec ajout de ferraillages) pour former un plancher. Note that the "floor frame elements" may be beams between which are intended to be placed slabs or interjoists, or pre-slabs, the assembly then being intended to be embedded in the concrete (if necessary with adding reinforcement) to form a floor.

Referring now to Figures 1 and 2, which can be seen a base beam 1 according to the invention, incorporated in the ground floor area of a building type construction.
Comme on peut le voir su r ces deux figu res, la poutre de soubassement 1 repose sur une longrine de fondation 3 coulée en place sur le terrain à bâtir, cette longrine pouvant être formée en béton armé. As can be seen in these two figures, the basement beam 1 is based on a foundation sill 3 cast in place on the building site, this sill can be formed of reinforced concrete.
Sur la poutre de soubassement 1 selon l'invention repose la première rangée d'agglomérés 5 de construction, pouvant être par exemple des parpaings ou des briques. On the underfloor beam 1 according to the invention lies the first row of agglomerates 5 of construction, which may be for example blocks or bricks.
La longrine 3 présente une largeur supérieure à celle de la poutre de soubassement 1 , définissant ainsi un épaulement 7 situé à l'intérieur du bâtiment à construire. Sur cet épaulement 7 sont disposés des demi-plots 9 destinés à supporter le plancher de rez-de-chaussée, formé en l 'espèce par la superposition d'une couche de matériau isolant 1 1 , d'un dallage 13 formé par exemple en béton armé et d'une couche de revêtement 15 pouvant par exemple consister en carrelage. The sill 3 has a width greater than that of the basement beam 1, thus defining a shoulder 7 located inside the building to be built. On this shoulder 7 are arranged half-pads 9 for supporting the floor of ground floor, formed in this case by the superposition of a layer of insulating material 1 1, a tiling 13 formed by example in reinforced concrete and a coating layer 15 may for example consist of tiling.
Ce plancher repose par ailleurs sur le terre-plein 17 sur lequel est construit le bâtiment grâce à des plots complets 19 répartis de manière homogène sur ce terre-plein de façon à reprendre les charges du plancher. This floor also rests on the platform 17 on which the building is built thanks to complete studs 19 distributed homogeneously on this platform so as to take up the loads of the floor.
Com me cela est conn u en soi, les agglomérés 5 peuvent comprendre, sur leur face située à l'extérieur du bâtiment, un revêtement approprié tel qu'un enduit 21. As is known per se, the agglomerates 5 may comprise, on their face located outside the building, a suitable coating such as a coating 21.
Sur leur face située à l'intérieur du bâtiment, ces agglomérés comprennent u n revêtement isolant 23 conn u , pouvant comprendre typiquement une couche de laine de verre ou de roche associée à des plaques de plâtre. On their face located inside the building, these agglomerates comprise an insulating coating 23 conn u, which can typically comprise a layer of glass wool or rock associated with plasterboard.
La poutre de soubassement 1 est un élément préfabriqué, c'est-à- d ire un élément fabriqué en usine avant util isation sur le chantier de construction. The basement beam 1 is a prefabricated element, that is, an element manufactured in the factory before use on the construction site.
Comme cela est particulièrement visible sur la figure 2, cette poutre de soubassement 1 comporte d'une part une partie structurelle 25, pouvant être formée par exemple en béton armé, et d'autre part une couche de matériau isolant 27, incorporée à la partie structurelle 25. En d'autres termes, la poutre de soubassement préfabriquée 1 arrive sur le chantier avec sa couche de matériau isolant 27 solidaire de la partie structurelle 25. As is particularly visible in FIG. 2, this base beam 1 comprises on the one hand a structural part 25, which can be formed for example of reinforced concrete, and on the other hand a layer of insulating material 27, incorporated in the part In other words, the prefabricated base beam 1 arrives on the site with its layer of insulating material 27 integral with the structural part 25.
Comme cela est visible sur la figure 2, la partie structurelle 25 est évidemment placée du côté extérieur du bâtiment, et la couche de matériau isolant 27 est placée à l'intérieur du bâtiment, dans la continuité de la couche 23 revêtant la face intérieure des éléments de construction 5. As can be seen in FIG. 2, the structural part 25 is obviously placed on the outside of the building, and the layer of insulating material 27 is placed inside the building, in the continuity of the layer 23 coating the inner face of the building. building elements 5.
Le matériau formant la couche isolante 27 peut être de toute nature appropriée, et de préférence choisi dans le groupe comprenant le polystyrène, la laine de verre, la laine de bois, la laine de roche, le chanvre, le liège, la mousse de polyuréthane. The material forming the insulating layer 27 may be of any suitable nature, and preferably selected from the group comprising polystyrene, glass wool, wood wool, rockwool, hemp, cork, polyurethane foam.
Le mode de fabrication de la poutre de soubassement préfabriquée 1 consiste par exemple à disposer la couche de matériau isolant 27 à l'intérieur d'un moule, dans lequel aura également été placé de manière préalable un ferraillage, puis à couler du béton dans ce moule, de manière d'une part à noyer le ferraillage et d'autre part à venir en prise avec la couche de matériau isolant 27. The manufacturing method of the prefabricated base beam 1 consists, for example, in arranging the layer of insulating material 27 inside a mold, in which a reinforcement has also been previously placed, and then pouring concrete into this mold. mold, so on the one hand to drown the reinforcement and secondly to come into engagement with the layer of insulating material 27.
Comme on peut le comprendre à la lumière de ce qui précède, la mise en œuvre d'une poutre de soubassement 1 selon l'invention permet, en une seule opération, de réaliser la base du mur extérieur du bâtiment, et d'isoler la face intérieure de ce mur, supprimant de la sorte le pont thermique qui aurait pu exister entre ce m u r et le planch er : aucune opération spécifique supplémentaire d'isolation n'est donc nécessaire. Dans le mod e d e réal isation de l a fig u re 3, la poutre de soubassement 1 et la longrine 3 du mode de réalisation précédent ne forment en fait qu'un seul et même élément, défin issant ainsi, par sa forme, l'épaulement 7 et incorporant, au-dessus de cet épaulement, la couche de matériau isolant 27. Ce mode de réalisation permet donc de s'affranchir de la nécessité de réaliser une longrine préalablement à la mise en place de la poutre de soubassement, comme c'était le cas pour le mode de réalisation des figures 1 et 2. As can be understood in the light of the above, the implementation of a base beam 1 according to the invention allows, in a single operation, to make the base of the outer wall of the building, and to isolate the the inner face of this wall, thereby eliminating the thermal bridge that could have existed between the wall and the floor: no additional specific operation of insulation is therefore necessary. In the embodiment of FIG. 3, the base beam 1 and the sill 3 of the preceding embodiment form in fact only one and the same element, thus defining, by its shape, the shoulder 7 and incorporating, above this shoulder, the layer of insulating material 27. This embodiment therefore eliminates the need to make a sill prior to the establishment of the base beam, as c ' was the case for the embodiment of Figures 1 and 2.
On a vu jusqu'à présent un exemple de poutre préfabriquée selon l'invention destinée à être utilisée à la hauteur du plancher du rez-de-chaussée, mais l'invention s'étend également aux poutres destinées à être utilisées pour les planchers d'étage. We have seen so far an example of a prefabricated beam according to the invention to be used at the height of the floor of the ground floor, but the invention also extends to the beams intended to be used for the floors of 'floor.
On se reporte donc à présent aux figures 4 à 6, sur lesquelles on a représenté un exemple de poutre d'étage selon l'invention. Comme on peut le voir sur ces figures, une telle poutre d'étage 1 comporte sur sa face située à l'intérieur du bâtiment, une pluralité d'équerres 29 renforcées par un nervurage 31 , ces équerres pouvant être fixées à la partie structurelle 25 de la poutre 1 par exemple par scellement ou par noyage dans le béton formant cette partie structurelle, lors du coulage du béton. Referring now to Figures 4 to 6, which shows an example of a floor beam according to the invention. As can be seen in these figures, such a stage beam 1 has on its face located inside the building, a plurality of brackets 29 reinforced by a ribbing 31, these brackets can be fixed to the structural part 25 of the beam 1 for example by sealing or flooding into the concrete forming this structural part, during the pouring of the concrete.
Comme dans les modes de réalisation précédents, une couche de matériau isolant 27 est incorporée à la poutre d'étage 1 , entre les équerres 29, mais également à l'intérieur de celles-ci : pour cela, lors de la fabrication de la poutre d'étage préfabriquée 1 , on insère des pains de matériau isolant 33 dans l'espace délimité par le nervurage 31. As in the previous embodiments, a layer of insulating material 27 is incorporated in the stage beam 1, between the brackets 29, but also inside them: for this, during the manufacture of the beam prefabricated floor 1, inserts of insulating material 33 are inserted in the space delimited by the ribbing 31.
On obtient de la sorte une isolation thermique de l'intégralité de la face intérieure de la poutre d'étage 1 , y compris dans les zones où se trouvent les équerres 29. In this way, a thermal insulation of the entire inner face of the floor beam 1 is obtained, including in the areas where the brackets 29 are located.
Sur ces équerres sont fixées de préférence par soudage des tiges filetées 35 aptes à coopérer avec des platines 37 solidaires de poutrelles préfabriquées 39. On these brackets are preferably fixed by welding threaded rods 35 adapted to cooperate with plates 37 integral with prefabricated beams 39.
Comme cela est connu en soi, de telles poutrelles préfabriquées constituent l'ossature du plancher et sont destinées à être reliées entre elles par des éléments de remplissage tels que des hourdis ou des entrevous. Ces poutrelles peuvent être par exemple en béton armé, ou bien du type à raidisseur et à profilé métallique rempli de mousse de polyuréthane (produit ISOLTOP ® - voir www.isoltop.com), ou bien encore du type à raidisseur et à profilé en matériau composite. As is known per se, such prefabricated beams are the framework of the floor and are intended to be interconnected by filling elements such as slabs or interjoists. These beams can for example be made of reinforced concrete, or of the stiffener and metal profile type filled with polyurethane foam (ISOLTOP ® product - see www.isoltop.com), or even of the stiffener and profiled material type. composite.
Pour sécuriser la liaison des poutrelles 39 avec les tiges filetées 35, on vient placer des boulons 41 sur ces tiges filetées. To secure the connection of the beams 39 with the threaded rods 35, we just place bolts 41 on these threaded rods.
De manière optionnelle, notamment dans les régions à risque sismique, on peut venir souder les platines 37 sur les tiges 35. Les équerres 29 peuvent être très facilement obtenues à partir de tronçons de poutres métalliques en « I », couramment désignées par IPN, dont on scie les ailes en biais (par exemple au moyen d'un disque diamanté) afin d'obtenir le nervurage 31 : un tel tronçon d'IPN est visible sur la figure 7, la partie enlevée par sciage pour obtenir le nervurage 31 étant représentée en pointillés ; une fois cette partie enlevée, on vient rapporter par soudage deux plaques P1 et P2 sur le tronçon d'IPN, la plaque P1 étant destinée à être noyée dans le béton formant la partie structurelle 25 de la poutre d'étage. Optionally, especially in regions at risk seismic, it is possible to weld the plates 37 on the rods 35. The brackets 29 can be very easily obtained from sections of metal beams in "I", commonly referred to as IPN, whose wings are sawed at an angle (for example by means of a diamond disc) in order to obtain the ribbing. : such a section of IPN is visible in Figure 7, the portion removed by sawing to obtain the ribbing 31 being shown in dashed lines; once this part is removed, two plates P1 and P2 are soldered to the IPN section by welding, the plate P1 being intended to be embedded in the concrete forming the structural part 25 of the stage beam.
Comme on peut donc le comprendre à la lumière de la description de ce mode de réalisation de poutre préfabriquée d'étage, on obtient là encore un moyen extrêmement rapide et efficace pour réaliser la rupture de ponts thermiques entre cette poutre d'étage et les poutrelles 39 (ainsi qu'avec le plancher associé qui sera par la suite coulé sur ces poutrelles). As can therefore be understood in the light of the description of this embodiment of prefabricated floor beam, we obtain here again an extremely fast and effective way to achieve the breaking of thermal bridges between this floor beam and the beams. 39 (as well as with the associated floor which will subsequently be poured on these beams).
Bien entendu, il faut comprendre que la mise en place des équerres est avantageusement réalisée en usine, de manière que la poutre d'étage préfabriquée 1 arrive entièrement prête, avec sa partie structurelle 25, sa partie isolante incorporée 27, 33, et les équerres associées 29. Of course, it should be understood that the positioning of the brackets is advantageously carried out in the factory, so that the prefabricated floor beam 1 arrives fully ready, with its structural part 25, its incorporated insulating part 27, 33, and the brackets associated 29.
La présente invention n'est nullement limitée aux modes de réalisations décrits et représentés. C'est ainsi que cette invention est généralisable à tout type d'élément préfabriqué incorporant une couche d'isolation permettant de rompre les ponts thermiques : de tels éléments préfabriqués peuvent être des éléments horizontaux, verticaux, ou obliques, ainsi que des éléments à bancher (ou « banches »), c'est-à-dire des éléments creux pouvant être remplis par exemple de béton. The present invention is not limited to the embodiments described and shown. Thus, this invention is generalizable to any type of prefabricated element incorporating an insulation layer for breaking thermal bridges: such prefabricated elements may be horizontal, vertical or oblique elements, as well as elements to be closed. (or "banches"), that is to say hollow elements that can be filled for example concrete.
C'est ainsi également que dans certaines applications on peut envisager que ces éléments préfabriqués soient disposés de manière que la couche de matériau isolant incorporée à ces éléments soit disposée non pas verticalement comme cela a été décrit dans les exemples précédents, mais de manière inclinée ou horizontalement : ce serait par exemple le cas si on utilisait de tels éléments préfabriqués entre un plancher de rez-de-chaussée et un terre-plein. It is thus also the case that in certain applications it is possible to envisage that these prefabricated elements are arranged in such a way that the layer of insulating material incorporated in these elements is arranged not vertically as described in the previous examples, but in an inclined manner or horizontally: this would be the case, for example, if such prefabricated elements were used between a ground floor and a platform.
C'est ainsi également que l'on peut envisager d'incorporer à l'élément préfabriqué selon l'invention un placage extérieur, formé par exemple par des briques plates 43, comme cela est visible sur les figures 4 et 5 : un tel placage peut être mis en place au moment du coulage de la partie structurelleIt is thus also possible to incorporate in the prefabricated element according to the invention an external veneer, formed for example by flat bricks 43, as can be seen in FIGS. 4 and 5: such a veneer can be put in place when pouring the structural part
25, dans le moule de fabrication de l'élément préfabriqué. 25, in the mold for manufacturing the prefabricated element.
C'est ainsi également que l'on pourrait envisager des éléments préfabriqués conformes à l'invention présentant toute autre forme que la forme rectiligne décrite ci-avant : cette forme pourrait notamment présenter une ou plusieurs courbures, un ou plusieurs décrochements, etc. Thus, it is also possible to envisage prefabricated elements according to the invention having any other shape than the rectilinear form described above: this shape could in particular have one or more curvatures, one or more recesses, etc.
Dans l'hypothèse où l'élément préfabriqué est courbe et utilisé en poutre d'étage, les équerres et platines solidaires des poutrelles de planchers correspondantes présentent bien entendu une courbure apte à épouser celle de l'élément préfabriqué. In the case where the prefabricated element is curved and used as a floor beam, the brackets and plates integral with the corresponding floor beams of course have a curvature adapted to match that of the prefabricated element.
C'est ainsi éqalement que l'on peut envisager de placer un autre pain isolant 45 en sous la plaque P2 de l'équerre 29, comme cela est représenté notamment aux figures 8 et 10 : un tel pain isolant contribue à la rupture du pont thermique. Thus it is also possible to consider placing another insulating bread 45 under the plate P2 of the bracket 29, as shown in particular in Figures 8 and 10: such insulating bread contributes to the breaking of the bridge thermal.
C'est ainsi également que l'on peut souder des fers 47 sur les équerres situées en vis-à-vis, comme cela est visible sur les figures 8 à 10, ces fers s'étendant alors le long des poutrelles 39. Thus it is also possible to weld irons 47 on the brackets facing each other, as can be seen in FIGS. 8 to 10, these irons then extending along the beams 39.
C'est ainsi également que l'on peut envisager des fers 49 soudés à la plaque P1 de chaque équerre 29, et noyés dans la partie structurelle 25 de l'élément préfabriqué 5, comme cela est visible aux figures 9 et 10. Thus, it is also possible to envisage irons 49 welded to the plate P1 of each bracket 29, and embedded in the structural part 25 of the prefabricated element 5, as can be seen in FIGS. 9 and 10.
C'est ainsi également que l'on peut envisager des réservations 51 formées dans la partie structurelle 25 de l'élément préfabriqué 5, de manière à permettre le passage de fers de renfort, comme cela est visible notamment sur les figures 8 et 9. It is thus also possible to envisage reservations 51 formed in the structural part 25 of the prefabricated element 5, so as to allow the passage of reinforcing irons, as can be seen in particular in Figures 8 and 9.
Les dispositions mentionnées dans les trois paragraphes qui précèdent permettent la réalisation de constructions parasismiques. C'est ainsi également que l'on peut réaliser un plancher avec une ossature formée par des pré-dalles 53 à la place des poutrelles 39, comme cela est visible sur les figures 1 1 à 15, qui représentent d'ailleurs également une construction satisfaisant aux normes parasismiques. The provisions mentioned in the three preceding paragraphs allow the realization of earthquake resistant constructions. Thus it is also possible to make a floor with a framework formed by pre-slabs 53 in place of the beams 39, as can be seen in FIGS. 1 to 15, which also represent a construction meeting seismic standards.
Les pré-dalles 53, beaucoup plus larges et moins hautes que les poutrelles 39, peuvent dans certains cas être jointives, et permettre ainsi de s'affranchir de la mise en œuvre de hourdis ou d'entrevous. The pre-slabs 53, much wider and lower than the beams 39, may in some cases be contiguous, and thus to overcome the implementation of slabs or interjoists.
Dans la variante visible aux figures 14 et 15, on peut voir que l'on a disposé des plaques de matériau composite 55 entre les plaques P1 des équerres 29 et la partie structurelle 25 de l'élément préfabriqué : ces plaques, qui peuvent par exemple être scellées sur les plaques P1 des équerres 29, permettent de renforcer l'effet de rupture de pont thermique. In the variant shown in FIGS. 14 and 15, it can be seen that plates of composite material 55 have been placed between the plates P1 of the brackets 29 and the structural part 25 of the prefabricated element: these plates, which may for example being sealed on the plates P1 of the brackets 29, make it possible to reinforce the thermal bridge breaking effect.
