Description

La présente invention concerne un élément de construction type "plancher" servant à la réalisation ou entrant dans la composition de planchers, de toitures, de terrasses, de murs porteurs ou non, ou de parois analogues.The present invention relates to a "floor" type construction element used for making or entering into the composition of floors, roofs, terraces, load-bearing walls or not, or similar walls.

Les éléments connus du type "plancher" de ce genre, réalisés sur chantier ou en usine, sont généralement d'un poids élevé et de manutention difficile. Ils camportent une poutrelle en béton armé ou en béton précontraint supportant un entrevous isolant, ou sont constitués par un coffrage isolant avec poutres incorporées. Ces montages sont très coûteux et n'associent pas toutes les qualités de bonne isolation thermique et phonique, d'excellente protection contre le feu et l'attaque des rongeurs. Ils peuvent présenter aussi des difficultés d'accrochage des enduits en sous-face et possèdent une isolation thermique et un degré coupe-feu médiocres du fait de l'hétérogénéité de la sous-face et de l'existence de "ponts thermiques".Known elements of the "floor" type of this kind, produced on site or in the factory, are generally of heavy weight and difficult to handle. They carry a reinforced concrete or prestressed concrete beam supporting an insulating interjoist, or consist of an insulating formwork with incorporated beams. These assemblies are very expensive and do not combine all the qualities of good thermal and sound insulation, excellent protection against fire and attack by rodents. They can also present difficulties in hanging the plaster on the underside and have poor thermal insulation and fire-resistance degree due to the heterogeneity of the underside and the existence of "thermal bridges".

L'élément de construction, objet de l'invention, est caractérisé par le fait qu'il possède à la fois des propriétés coupe-feu, des propriétés de légèreté, d'isolation thermique, d'isolation phonique et de protection contre l'attaque des rongeurs pour un faible prix de revient.The building element which is the subject of the invention is characterized by the fact that it has at the same time fire-resistant properties, properties of lightness, thermal insulation, sound insulation and protection against rodent attack for a low cost price.

L'élément de grande dimension ainsi caractérisé comporte :

  • - des panneaux fibragglo (ou autres matériaux isolant ayant des qualités coupe-feu) sur toute sa face inférieure ;
  • - des éléments inteanédiaires en matière plastique alvéolaire expansée (ou autre matériau léger isolant faisant office de remplissage). Ces éléments sont fixés sur les panneaux fibragglo ;
  • - des éléments intermédiaires dénommés poutrelles, en béton armé ou béton précontraint jouant le rôle porteur, coulés partiellement ou en totalité sur les panneaux fibragglo et entre les éléments intermédiaires en matériau léger isolant.
The large element thus characterized comprises:
  • - fibragglo panels (or other insulating materials with fire-resistant qualities) on its entire underside;
  • - intermediate elements made of expanded cellular plastic material (or other light insulating material serving as filling). These elements are fixed on the fibragglo panels;
  • - intermediate elements called beams, in reinforced concrete or prestressed concrete playing the load-bearing role, partially or wholly cast on the fibragglo panels and between the intermediate elements in light insulating material.

La partie supérieure de l'élément de construction reçoit, en usine ou ul- térieursnent sur chantier, soit une couche de béton, soit un matériau .d'étanchéité ou une couche de finition. La sous-face de l'élément de construction peut rester brute, être préenduite ou encore enduite sur chantier.The upper part of the building element receives, in the factory or later on site, either a layer of concrete, or a sealing material or a finishing layer. The underside of the building element can remain rough, be pre-coated or coated on site.

lorsque l'élément de construction est utilisé pour réaliser un plancher ou une paroi inclinée, l'appui sur les murs de rive se fait soit par pose de la sous-face fibragglo sur la maçonnerie sur une largeur de quelques cen- timètres, soit par pose de l'extrémité de la poutrelle sur la maçonnerie.when the building element is used to make a sloping floor or wall, the support on the edge walls is done either by laying the fibragglo underside on the masonry over a width of a few centimeters, or by laying the end of the beam on the masonry.

La description des formes de réalisation suivantes, faite à titre d'exemple, permettra de mieux comprendre l'invention.The description of the following embodiments, given by way of example, will allow a better understanding of the invention.

La figure 1 représente une coupe transversale de l'élément de construction constitué par une sous-face en panneau fibragglo (1), des éléments inter- . médiaires en matière plastique alvéolaire (2) et des poutrelles en béton (3). Une dalle de répartition ou dalle de compression- (4) est réalisée sur les éléments (2) et (3), soit en usine de préfabrication, soit sur chantier.Figure 1 shows a cross section of the building element consisting of a fibragglo panel underside (1), inter- elements. honeycomb plastic media (2) and concrete beams (3). A distribution slab or compression slab - (4) is produced on elements (2) and (3), either in the prefabrication factory or on site.

La figure 2 représente une réalisation particulière de l'élément de construction en préfabrication partielle, suivant une coupe transversale. La largeur de l'élément est de l'ordre de 50 à 60 cm, sa longueur est variable et peut atteindre environ 10 mètres.Figure 2 shows a particular embodiment of the building element in partial prefabrication, in a cross section. The width of the element is of the order of 50 to 60 cm, its length is variable and can reach approximately 10 meters.

Les éléments en matière plastique alvéolaire (2) comportent sur leurs faces latérales un tenon (5) et une mortaise (6) qui assurent le clavetage ou la bonne liaison entre les éléments juxtaposés sur chantier. Sur leurs faces intérieures les éléments (2) comportent chacun une rainure (7) dans laquelle pénètre le béton de la poutrelle (8). Suivant la réalisation de la figure 2, seule la base de la poutrelle (8) a été coulée. Le complément de béton de la nervure ainsi que la dalle de répartition sont réalisés sur chantier.The cellular plastic elements (2) comprise on their lateral faces a tenon (5) and a mortise (6) which ensure the keying or the good connection between the elements juxtaposed on site. On their inner faces the elements (2) each have a groove (7) into which the concrete of the beam (8) penetrates. According to the embodiment of Figure 2, only the base of the beam (8) was poured. The additional concrete in the rib and the distribution slab are made on site.

La figure 3 présente la juxtaposition des éléments préfabriqués tels que décrit sur la figure 2.FIG. 3 shows the juxtaposition of the prefabricated elements as described in FIG. 2.

L'appui des éléments de plancher sur les murs de rive peut se réaliser suivant la figure 4 qui représente une coupe longitudinale au droit de la poutrelle en béton. Dans ce cas l'élément préfabriqué repose sur le mur de rive ou l'appui intermédiaire par la sous-face en fibragglo (1), sur une largeur de 2 à 3 cm. Après réalisation du complément de la nervure en béton et de la dalle de compression (4) les charges du plancher sont transmises au mur support (11) sans solliciter la sous-face en fibragglo à un effort de compression.The support of the floor elements on the edge walls can be achieved according to Figure 4 which shows a longitudinal section to the right of the concrete beam. In this case the prefabricated element rests on the edge wall or the intermediate support by the fibragglo underside (1), over a width of 2 to 3 cm. After completion of the complement of the concrete rib and the compression slab (4), the floor loads are transmitted to the support wall (11) without stressing the fibragglo underside at a compression force.

L'appui des éléments de planchers sur les nurs de rive peut aussi se réaliser suivant la figure 5 schématisant une coupe longitudinale au droit d'une poutrelle. L'élément de plancher repose sur le mur de rive par appui direct de la poutrelle en béton. Cette dernière comporte un talon (12) permettant cet appui. Le talon est réalisé en préfabrication, au moment du coulage de la base de la poutrelle grâce à une découpe effectuée au préalable dans la base en fibragglo. La figure 5a montre en perspective la découpe (13) réalisée dans la plaque de fibragglo.The support of the floor elements on the edge nurses can also be achieved according to FIG. 5 schematically showing a longitudinal section in line with a beam. The floor element rests on the edge wall by direct support of the concrete beam. The latter comprises a heel (12) allowing this support. The heel is made in prefabrication, at the time of the casting of the base of the beam thanks to a cut made beforehand in the fibragglo base. Figure 5a shows in perspective the cutout (13) made in the fibragglo plate.

Les figures 6 et 6a représentent une autre forme de réalisation de l'élément de construction, sans dalle de compression ou dalle de répartition. Les éléments intermédiaires isolants (14) sont découpés suivant un profil (15) formant coffrage d'une poutrelle en béton armé ou suivant un profil (16) formant coffrage d'une poutrelle en béton préoontraint.Figures 6 and 6a show another embodiment of the building element, without compression slab or distribution slab. The insulating intermediate elements (14) are cut along a profile (15) forming the formwork of a reinforced concrete beam or according to a profile (16) forming the formwork of a prestressed concrete beam.

Ces formes de réalisation peuvent être employées pour construire des toitures inclinées. les éléments de construction sont posés soit dans le sens , de la pente de la toiture en prenant appui sur le faite de la toiture et la façade, soit perpendiculairement au sens de la toiture en prenant appui sur les pignons et refends.These embodiments can be used to construct pitched roofs. the construction elements are placed either in the direction of the slope of the roof by resting on the roof and the facade, or perpendicular to the direction of the roof by resting on the gables and split.

L'élément de construction préfabriqué, objet de l'invention, peut être utilisé dans tous les cas où il est demandé la réalisation de planchers, de toitures, de murs ou de parois analogues qui doivent posséder à la fois des propriétés d'isolation thermique, d'isolation phonique, de protection au feu et de protection contre l'attaque des rongeurs, de légèreté, de faible prix de revient et de mise en oeuvre rapide.The prefabricated building element, object of the invention, can be used in all cases where the production of floors, roofs, walls or the like is required, which must have both thermal insulation properties , sound insulation, fire protection and protection against attack by rodents, lightness, low cost price and rapid implementation.
