Thermal insulation (12) is contained in the space between the webs and there is a reinforced concrete compression slab (14). Between the concrete slab and the thermal insulation is an air space (13) ensuring complementary thermal and acoustic insulation.

Description

La présente invention concerne un plancher utilisé pour la construction de bâtiment comportant au moins un profilé métallique en forme de U présentant deux âmes, plis longitudinaux situés de part et d'autre d'une plage, un moyen d'isolation thermique contenu dans l'espace entre les âmes du profilé, et une dalle de compression en béton armé.The present invention relates to a floor used for the construction of building comprising at least one U-shaped metal profile having two webs, longitudinal folds located on either side of a beach, a means of insulation thermal contained in the space between the webs of the profile, and a compression slab in reinforced concrete.
Il est connu du brevet FR 2 333 107 un coffrage métallique, pour l'exécution de constructions en béton, plus spécialement des dalles, présentant, en même temps, un coffrage et une armature pour béton. En d'autres termes, le document cité concerne la construction de dalles en béton qui, d'une manière générale, sont formées par une partie inférieure coffrage, en acier, pouvant être revêtu, et une partie supérieure en béton coulé dans ledit coffrage, une partie du coffrage étant comblé d'un matériau isolant.It is known from patent FR 2 333 107 a metal formwork, for the execution of concrete constructions, more particularly slabs, having, at the same time, a formwork and reinforcement for concrete. In other words, the document cited concerns the construction of concrete slabs which, in general, are formed by a formwork lower part, in steel, can be coated, and upper part in concrete poured into said formwork, part of the formwork being filled with a material insulating.
Il est connu que de telles constructions exigent des éléments formant une liaison entre le coffrage perdu en acier et la dalle en béton et, dans ce but, la surface supérieure des coffrages en acier est, d'une manière générale, pourvue de moyens formant cette liaison entre l'acier et le béton afin de réduire les tensions d'efforts rasants entre acier et béton. Ces moyens peuvent, dans la plupart des cas, également servir d'armature pour le béton.It is known that such constructions require elements forming a connection between the lost steel formwork and the concrete slab and, for this purpose, the surface of steel formwork is generally provided with means forming this connection between steel and concrete in order to reduce grazing stress tensions between steel and concrete. These means can, in most cases, also be used of reinforcement for concrete.
Dans ce document, les coffrages sont pourvus de petites nervures sur lesquelles sont placées des plaques ou blocs de mousse rigide de polyuréthane ou d'un matériau similaire. Un treillis soudé est posé sur des ailes du coffrage, avant la coulée du béton. Pour la réalisation d'un plafond acoustique, le profilé est perforé.In this document, the forms are provided with small ribs on which are placed plates or blocks of rigid polyurethane foam or material similar. A welded mesh is placed on the wings of the formwork, before the concrete is poured. For the realization of an acoustic ceiling, the profile is perforated.
Cette structure permet de réduire l'épaisseur de la dalle de compression tout en augmentant l'inertie totale de la dalle mixte acier/béton. En outre, elle assure une isolation thermique dans de nombreux cas.This structure makes it possible to reduce the thickness of the compression slab while increasing the total inertia of the mixed steel / concrete slab. In addition, it provides thermal insulation in many cases.
Le plancher, décrit dans le document cité, ne remplit pas les conditions optimum en matière d'isolation thermique, d'isolation phonique et de rapport masse sur charge. Le but de l'invention est de présenter un perfectionnement de d'art antérieur cité dans le domaine de la simplification de la construction ainsi que dans le domaine des performances techniques comme notamment, la tenue à la charge par rapport à la masse du plancher, l'isolation phonique, l'isolation thermique. Le plancher favorise aussi une réalisation sur chantier ainsi qu'une industrialisation en préfabriqué.The floor, described in the cited document, does not meet the optimum conditions in terms of thermal insulation, sound insulation and mass-to-charge ratio. The object of the invention is to present an improvement of prior art cited in the simplification of construction as well as in the field of technical performance such as, in particular, the resistance to load compared to the floor mass, sound insulation, thermal insulation. The floor favors also a construction on site as well as a prefabricated industrialization.

    Selon l'invention, le plancher 1 utilisé pour la construction de bâtiment est composé comme présenté sur la figure 1, de profilés métalliques 2 en forme de U présentant une plage 3 et deux âmes 4, 5, pouvant être de formes différentes, ces âmes 4, 5 étant réalisées par pliages longitudinaux d'un flan de tôle. Les profilés sont juxtaposés les uns aux autres pour former un coffrage par l'emboítement d'une âme 4 d'un profilé avec l'âme 5 du profilé concomitant. Chacune des deux âmes de chacun des profilés comporte respectivement, des pliures 6, 7, 8 pour emboítement. L'emboítement présente notamment les avantages de pouvoir aligner les profilés dans le plan du coffrage et de pouvoir fermer la jointure entre les profilés au passage du béton liquide au moment de la coulée.According to the invention, the floor 1 used for building construction is composed as shown in Figure 1, of metal profiles 2 in the form of U having a track 3 and two cores 4, 5, which can be of different shapes, these webs 4, 5 being produced by longitudinal folding of a sheet blank. The profiles are juxtaposed with each other to form a formwork by nesting a core 4 of a profile with the core 5 of the concomitant profile. Each of the two souls of each profiles respectively comprises folds 6, 7, 8 for interlocking. The interlocking has in particular the advantages of being able to align the profiles in the formwork plan and to be able to close the joint between the profiles when passing the liquid concrete at the time of pouring.
    De plus, au moins une partie des pliures 6, 7, forme un plan parallèle à la dalle pour permettre la pose d'un treillis 9 soudé d'armature du béton armé. Les armatures sous la forme de treillis 9 soudés sont toujours liées à leur base, du type coffrage, hourdis, pour éviter qu'elles remontent à la surface du béton coulé liquide, par l'effet de la poussée d'Archimède.In addition, at least part of the folds 6, 7, form a plane parallel to the slab. to allow the installation of a welded mesh 9 for reinforcing reinforced concrete. The frames in the form of welded mesh 9 are always linked to their base, of the formwork type, slabs, to prevent them from rising to the surface of poured concrete, by the effect of Archimedes' push.
    Selon l'invention, le treillis soudé est placé en appui sur les surfaces planes des pliures 6,7 puis lié à une partie des pliures par des moyens choisis parmi, une soudure, par exemple par point, la partie plane assurant un bon contact mécanique et électrique pour ce type de liaison ; un accrochage par une découpe localisée de la pliure de l'âme, découpe formant une languette 10, 11 relevée puis rabattue sur un rond du treillis soudé ; un lien métallique indépendant comme par exemple un clip maintenant par pincement le treillis soudé à l'armature ou encore, un fil métallique.According to the invention, the welded mesh is placed in abutment on the flat surfaces of the folds 6,7 then linked to a part of the folds by means chosen from, a weld, for example by point, the flat part ensuring good mechanical and electrical contact for this type of connection; attachment by localized cutting of the fold of the core, cutout forming a tongue 10, 11 raised then folded over a round of the trellis welded ; an independent metal link such as a clip now by pinch the mesh welded to the frame or a metal wire.
    L'ensemble les liaisons citées peuvent être réalisées sur le chantier ou en usine. Selon l'invention, le plancher comporte des moyens d'isolation 12, 13, contenu dans l'espace situé entre les âmes 4,5 des profilés 2 et entre la plage 3 du profilé et la dalle de béton 14 armé du treillis soudé 9. Les moyens d'isolation 12,13 comprennent d'une part, un matériau solide 12, placé sur la plage 3 et d'autre part, un espace d'air 13 situé entre l'isolation solide 12 et la dalle 14 assurant une isolation phonique associée à une isolation thermique complémentaire.All the connections mentioned can be carried out on site or in the factory. According to the invention, the floor comprises insulation means 12, 13, contained in the space between the cores 4,5 of the profiles 2 and between the area 3 of the profile and the slab of concrete 14 reinforced with the welded mesh 9. The insulation means 12, 13 include a on the one hand, a solid material 12, placed on the track 3 and on the other hand, an air space 13 located between the solid insulation 12 and the slab 14 ensuring sound insulation associated with a additional thermal insulation.
    Une lame d'air de préférence, supérieure à 3 cm, sans circulation, est reconnue comme étant un des meilleurs isolant thermique. Si ce moyen est connu dans le cas de parois isolantes verticales, il n'est nullement envisagé dans la construction de plancher du fait que le coffrage de plancher et un contenant généralement comblé de la matière liquide qu'est le béton lors de son emploi.An air gap preferably, greater than 3 cm, without circulation, is recognized as one of the best thermal insulators. If this means is known in the case of vertical insulating walls, it is not at all envisaged in the construction of floors the fact that the floor formwork and a container usually filled with material liquid that is concrete when used.
    On entend par lame d'air sans circulation un espace d'air fermé ne permettant pas un mouvement et ou un renouvellement de l'air. Un mouvement et ou un renouvellement de l'air dans cet espace ne permettrait plus d'assurer la fonction d'isolation thermique et ou phonique du plancher.Air flow without circulation means a closed air space that does not allow not a movement and or a renewal of the air. A movement and or a air renewal in this space would no longer ensure the function thermal and / or sound insulation of the floor.
    Pour la réalisation de cette espace d'air, selon l'invention, il est prévu l'usage d'un noyau 15, comme présenté sur la figure 2, supportant la masse de béton encore liquide, avant solidification. Le noyau 15 peut être solide et amovible, déplaçable longitudinalement au profilés après solidification du béton, notamment dans l'hypothèse d'une réalisation de plancher préfabriqué. Le noyau 15 peut être un coussin d'air pouvant être alvéolaire ou une enveloppe contenant un fluide pouvant être vidangé. Le coussin ou l'enveloppe peuvent rester enfermés dans la structure du plancher. La forme du noyau ménagé dans l'espace entre l'isolation solide 12 et la dalle 14 permet un dégagement 16 au niveau de la juxtaposition des profilés 2, pour permettre au béton coulé d'enrober une partie 17, 18 des âmes des profilés 4, 5, et pour réaliser une poutrelle armée associée à la dalle de béton armé. Le noyau peut rester à demeure, et peut être constitué d'une boíte alvéolée ou non alvéolée, de toute matière telle que métal, polystyrène, carton gommé ou goudronné.For the realization of this air space, according to the invention, provision is made for the use a core 15, as shown in Figure 2, supporting the mass of concrete still liquid, before solidification. The core 15 can be solid and removable, displaceable longitudinally to the profiles after solidification of the concrete, in particular in the hypothesis of a prefabricated floor realization. The core 15 can be an air cushion may be cellular or an envelope containing a drainable fluid. The cushion or envelope may remain enclosed in the floor structure. The form of the core formed in the space between the solid insulation 12 and the slab 14 allows a clearance 16 at the juxtaposition of the profiles 2, to allow the concrete cast to coat a part 17, 18 of the cores of the sections 4, 5, and to produce a reinforced beam associated with the reinforced concrete slab. The nucleus can remain permanently, and can be made of a honeycombed or non-honeycombed box, of any material such as metal, polystyrene, gummed or tarred cardboard.
    L'espace d'air 13, dans un autre exemple d'application, comme représenté sur la figure 3, peut être réalisé par l'usage d'un panneau 20, légèrement voûté supportant la masse de béton encore liquide. Le panneau 20 en voûte est par exemple, une tôle préformée arc-boutée en appui, soit sur les âmes 4,5 des profilés 2, soit sur le moyen d'isolation rigide 12. Le panneau peut être en toute matière, comme le noyau 15.The air space 13, in another example of application, as shown in the Figure 3, can be achieved by the use of a panel 20, slightly arched supporting the mass of concrete still liquid. The panel 20 in the vault is for example, a sheet preformed braced in support, either on the webs 4,5 of the profiles 2, or on the medium rigid insulation 12. The panel can be of any material, like the core 15.

    • le coffrage obtenu avec le seul assemblage des profilés selon l'invention est parfaitement étanche en soi,
    • chaque profilé peut présenter sur la plage 3, plusieurs nervures 21 ou plis crénelés longitudinaux permettant ainsi de fabriquer des coffrages de grande largeur, et assurant le montage de panneaux de plâtre en sous plancher.
    • une grande efficacité par l'emploi de treillis soudé pour béton fixés préalablement en usine sur l'une ou deux des âmes.

    • each profile may have on the area 3, several ribs 21 or longitudinal crenellated folds thereby making it possible to form large width formwork, and ensuring the mounting of plaster panels in the subfloor.
    • high efficiency by the use of welded mesh for concrete previously fixed in the factory on one or two of the cores.
    Il est précisé que:
    • le plancher selon l'invention est destiné à la réalisation notamment d'habitat individuel, collectif, administratif, industriel et tertiaire,
    • le plancher assure la réalisation de portées jusqu'à 6 ou 7m avec une flèche inférieure ou égale à 1/500 et des surcharges d'exploitation jusqu'à 500 daN/m2,
