Description

  

  Dalle en béton armé et procédé pour sa     fabrication       Le présent brevet comprend une dalle en  béton armé, caractérisée par le fait qu'elle porte  dans sa face inférieure, des poutres partielle  ment encastrées supportant entre elles des pla  ques isolantes du bruit et de la chaleur, dis  posées sous ladite face inférieure de la dalle.  



  Le brevet comprend aussi un procédé de  fabrication de la dalle ci-dessus définie, selon  lequel on forme au moyen des poutres et des  plaques qu'elles supportent, un coffrage dans  lequel on coule du béton.  



  Le dessin annexé représente, à     titre    d'exem  ple, en coupe verticale, une forme d'exécution  de la dalle objet d'une des inventions.  



  La dalle composite en béton 1 représentée,  est armée de ferrures 2 et 3, et porte dans sa  face inférieure l', des poutres 4 partiellement  encastrées dont les extrémités sont supportées  par les murs non figurés d'un édifice pour le  quel la dalle doit constituer, par exemple, un  plafond-plancher.  



  Les poutres en bois 4 portent sur la partie  inférieure non encastrée, de leurs faces laté  rales, des liteaux 5 sur lesquels reposent des  plaques isolantes 6 faites d'un aggloméré de  fibres de bois et de fibres de verre. Ces plaques  6, isolantes du bruit et de la chaleur, touchent  la face     inférieqre    l' de la dalle en béton. Une  couche de plâtre délimitée par le trait mixte 7,    peut être posée sous les plaques 6 pour     servir     de plafond.  



  On peut fabriquer la dalle qui vient d'être  décrite, sans avoir à confectionner un coffrage  spécial qui serait ensuite détruit. A cet effet,  on fixe les liteaux 5 sur les faces     latérales    des  poutres 4 et dispose sur les taquets, entre les  poutres, les plaques isolantes 6. L'ensemble des  poutres 4 et des plaques 6 constitue un cof  frage muni d'armatures 2 et 3, dans lequel on  coule du béton jusqu'au-dessus de la face su  périeure 4' des poutres, pour réaliser la dalle.  Les poutres 4 sont donc partiellement encas  trées dans le béton quand celui-ci a fait prise.



  Reinforced concrete slab and method for its manufacture This patent includes a reinforced concrete slab, characterized by the fact that it carries in its lower face, partially embedded beams supporting between them plates insulating noise and heat. , placed under said lower face of the slab.



  The patent also includes a method of manufacturing the slab defined above, according to which is formed by means of the beams and the plates which they support, a formwork in which concrete is poured.



  The appended drawing represents, by way of example, in vertical section, an embodiment of the slab which is the subject of one of the inventions.



  The composite concrete slab 1 shown, is reinforced with fittings 2 and 3, and carries in its lower face the, partially embedded beams 4 whose ends are supported by the walls not shown in a building for which the slab must constitute, for example, a ceiling-floor.



  The wooden beams 4 bear on the lower part not embedded, of their lateral faces, battens 5 on which rest insulating plates 6 made of an agglomerate of wood fibers and glass fibers. These plates 6, insulating against noise and heat, touch the lower face of the concrete slab. A layer of plaster delimited by the mixed line 7 can be placed under the plates 6 to serve as a ceiling.



  The slab which has just been described can be manufactured without having to make a special formwork which would then be destroyed. For this purpose, the battens 5 are fixed on the lateral faces of the beams 4 and placed on the cleats, between the beams, the insulating plates 6. The set of beams 4 and plates 6 constitutes a box fitted with reinforcements 2 and 3, in which concrete is poured up to the top of the upper face 4 'of the beams, to make the slab. The beams 4 are therefore partially embedded in the concrete when the latter has set.

Claims

CLAIM I: Reinforced concrete slab, characterized by the fact that it carries in its lower face, partially embedded beams supporting between them noise and heat insulating plates, arranged under said lower face of the slab. SUB-CLAIMS 1. Slab according to claim I, charac terized in that the beams are provided, on their side faces, with battens supporting said insulating plates. 2. Slab according to claim I, characterized in that said insulating plates are made of an agglomerate of wood fibers and glass fibers.

CLAIM II: Process for the manufacture of the slab according to claim I, characterized by the fact that support beams are connected by their base by means of insulating plates to constitute a formwork and concrete is poured into the latter. up to the top of the upper face of the beams, so that they are embedded in the concrete slab when this has set.
