Abstract

The prefabricated element makes or forms part of floors, roofs, terraces or load bearing walls, and it has large dimensions. It has a fire and humidity resistant material on its bottom face that forms a direct support for finishing coatings. The bottom face is reinforced and compressed plaster board (1) and a layer of plastic cellular insulation (2) spans between spaced concrete beams (3) to support the top compression slab (4).

Description

Le brevet principal auquel se rattache la présente addition concerne un élément de construction type "plancher" servant a la réalisation ou entrant dans la composition de planchers, de toitures, de terrasses, de murs porteurs ou non, ou de parois analogues. The main patent to which the present addition relates 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.

L'addition se rattache aux revendications 1, 2, 4 et 5 du brevet principal et concerne la nature du revêtement infgrieur de I'élément de construction. The addition relates to claims 1, 2, 4 and 5 of the main patent and relates to the nature of the lower coating of the building element.

L'élément de construction, objet de l'invention, est caractérisé par le fait qu'il possède a la fois des propriétés coupe-feu, des propriétés de légèreté, d'isolation thermique et d'insensibilité a l'humidité. The building element, object of the invention, is characterized in that it has both fire-resistant properties, properties of lightness, thermal insulation and insensitivity to moisture.

L'élément de construction ainsi caractérisé comporte en face infe- rieure une plaque de platre armé à l'aide de fibres de cellulose, comprimé et calibré. Sur ces plaques sont fixes des éléments intermediaires en matériau léger et isolant, par exemple en matière plastique alvéolaire. Le rôle porteur est assuré par un élément intermédiaire en beton armé ou béton précontraint coulé partiellement ou en totalité entre les éléments intermé- diaires en materiau léger isolant. The construction element thus characterized comprises on the lower face a plaster plate reinforced with cellulose fibers, compressed and calibrated. On these plates are fixed intermediate elements made of light and insulating material, for example of cellular plastic. The supporting role is provided by an intermediate element of reinforced concrete or prestressed concrete partially or entirely poured between the intermediate elements of light insulating material.

En règle générale, la poutrelle est réalisée en atelier de prefabrication. L'élément de construction de grande dimension comporte une ou plusieurs poutrelles longitudinales et éventuellement un raidisseur transversal ou o1 evideuent permettant la réalisation du raidisseur transversal sur chantier, après la pose des éléments de construction. As a rule, the beam is produced in a prefabrication workshop. The large construction element comprises one or more longitudinal beams and possibly a transverse or o1 recess stiffener allowing the realization of the transverse stiffener on site, after the installation of the construction elements.

Lorsqu'il s'agit d'une réalisation de plancher, l'appui de ltelement de construction sur les murs de rives se réalise soit par pose de la çous- face plâtre armé comprimé sur la maçonnerie sur une largeur de quelques centimètres, soit par pose de l'extrinite de la poutrelle surlamaçonnerie.  In the case of a floor construction, the support of the building element on the shore walls is achieved either by laying the compressed reinforced plaster underlay on the masonry over a width of a few centimeters, or by installation of the end of the masonry beam.

La description des formes de réalisation suivantes, faite a titre d'exemple permettra de mieux ccmprendre l'invention. The description of the following embodiments, given by way of example, will make it easier to understand the invention.

La figure I représente une coupe transversale de l'élément de construction, constitué par une sous-face en plaque de platre armé comprimé (1), des éléments intermédiaires en 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 I shows a cross section of the building element, consisting of an underside of compressed reinforced plaster plate (1), intermediate elements in cellular plastic (2) and concrete beams (3). A distribution slab or compression slab (4) is produced on the 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. Figure 2 shows a particular embodiment of the building element in partial prefabrication, in a cross section.

La largeur de l'élément est de l'ordre de 50 - 60 cm, sa longueur est variable et peut atteindre environ 10 metres. Les éléments en matiere plas tique 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 intérieuiésles 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 repartition sont réalisés sur chantier.The width of the element is of the order of 50 - 60 cm, its length is variable and can reach around 10 meters. The elements in cellular plastic material (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. The elements (2) on their interior faces 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 as well as the distribution slab are made on site.

La figure 3 représente une seconde réalisation particulière de l'élé- ment de construction en préfabrication partielle suivant une coupe transversale. FIG. 3 shows a second particular embodiment of the building element in partial prefabrication in a cross section.

Les éléments en matière plastique alvéolaire comportent un profil tel qu'il permet de réaliser isolation thermique de la nervure en béton par suite de la continuite de l'isolant (9) en sous-face de cette nervure en béton. The cellular plastic elements have a profile such that it allows thermal insulation of the concrete rib as a result of the continuity of the insulator (9) on the underside of this concrete rib.

Le bon accrochage de la bous-face en plaque de plâtre armé et comprimé à la nervure en béton est assure par l'intermédiaire d'éléments de fixation métalliques ;% tels que vis, clous, spirales, étriers ou autres acces- soires. The good attachment of the bous-face in reinforced plasterboard and compressed to the concrete rib is ensured by means of metallic fasteners;% such as screws, nails, spirals, stirrups or other accessories.

L'elément de construction préfabriqué, objet de l'invention, peut étre utilisé dans tous les cas ou il est demandé la realisation de planchers, de toitures, de murs, ou de parois analogues qui doivent posséder à la fois des proprietés d'isolation thermique, d'isolation phonique, de protection au feu et de protection contre l'attaque des rongeurs, de légèreté et de faible prix de'revient et présentant une sous-face, coupe-feu, finie prête à peindre ou à tapisser.  The prefabricated building element, object of the invention, can be used in all cases where it is requested the realization of floors, roofs, walls, or similar walls which must have both insulating properties thermal, soundproofing, fire protection and protection against attack by rodents, lightness and low price come back and having an underside, fire-rated, ready to paint or wallpaper.
