Description

  

  <B>Poutrelle.</B>    L'objet de la présente invention est une  poutrelle composée d'éléments qui peuvent  être en terre cuite et de fers d'armature. Cette  poutrelle est, caractérisée par le fait. qu'elle  est. formée par la réunion d'éléments placés  bout. à bout. présentant plusieurs cellules lon  <B>g</B>     itudinales    séparées par des cloisons, une des  cellules de chaque élément étant ouverte vers  le bas, de faon à former à la     surface    infé  rieure de la poutrelle un canal longitudinal       Wurné    vers le bas et. s'étendant sur toute la       longueur    de la poutrelle, ce canal étant rem  pli de béton dans lequel est. noyé un fer d'ar  mature.  



  Le     dessin    ci-joint représente. à titre  d'exemple, deux formes d'exécution d'une       poutrelle    conforme à la présente invention.  



  Les     fig.    1 et 2 montrent deux éléments de  céramique entrant, dans la composition de la.  poutrelle et dont, la seule différence est dans  le nombre des cellules qu'ils présentent.  



  lia     fig.    3 montre un tronçon de poutrelle.  Dans toutes les     figures,    les     éléments    cor  respondants sont désignés par les mêmes chif  fres de référence.  



  La poutrelle est composée, ainsi qu'on l'a  dit, par un certain nombre d'éléments selon  la     fig.    1 ou la     fig.    2.  



  Ces éléments qui sont tous semblables, sont  des pièces de terre cuite comportant un nom  bre quelconque de cellules longitudinales 6,  par exemple huit     (fig.    1) ou sept     (fig.    2),    séparées par des cloisons 7, l'une des cellules  étant ouverte vers le bas de faon à former,  dans la poutrelle, un canal longitudinal 1 ou  vert sur l'une de ses faces principales, dési  gnée par face     inférieure.    La poutrelle     est,    en  outre, munie de rebords 2 ménagés sur les  arêtes entre la face inférieure et les deux  autres faces principales adjacentes, lesdits  rebords 2 prolongeant ladite face.

   inférieure,  et de chanfreins 3 ménagés sur les deux au  tres arêtes parallèles aux rebords susdits, les  dits chanfreins 3     coupant    les arêtes de la par  tie supérieure de la poutrelle parallèlement  aux rebords 2.  



  Pour construire la poutrelle. on place les  éléments les uns derrière les autres     (fig.        3a,    b,  c... ) leurs canaux 1 constituant un seul canal  qui occupe toute la     longueur    de la poutrelle.  On remplit le canal 1 de ciment 5 en     noyant     dans la masse de ce ciment un fer d'armature  dont les extrémités dépassent à l'extérieur des  plans verticaux limitant chacun des éléments  extrêmes de la poutrelle.  



  Les rebords 2 ont. pour but. d'empêcher  qu'au moment où l'on place côte à côte les  poutrelles, afin de constituer un plancher,  leurs parements verticaux ne viennent en con  tact les uns avec les autres, mais plutôt que  les rebords 2 viennent en contact, afin que  l'on ait entre les deux poutrelles un canal  dont le fond est constitué par la réunion des       deiLx    rebords.



  <B> Beam. </B> The object of the present invention is a beam composed of elements which may be made of terracotta and reinforcing bars. This beam is characterized by the fact. which is. formed by the union of elements placed end. exhausted. having several lon <B> g </B> itudinal cells separated by partitions, one of the cells of each element being open downwards, so as to form on the lower surface of the joist a longitudinal Wurné channel downwards and . extending over the entire length of the joist, this channel being filled with concrete in which is. drowned a mature ar iron.



  The attached drawing represents. by way of example, two embodiments of a joist according to the present invention.



  Figs. 1 and 2 show two ceramic elements entering into the composition of the. joist and of which, the only difference is in the number of cells they present.



  lia fig. 3 shows a section of joist. In all the figures, the corresponding elements are designated by the same reference numbers.



  The beam is composed, as has been said, by a certain number of elements according to FIG. 1 or fig. 2.



  These elements, which are all similar, are pieces of terracotta comprising any number of longitudinal cells 6, for example eight (fig. 1) or seven (fig. 2), separated by partitions 7, one of the cells. being open downwards so as to form, in the beam, a longitudinal or green channel 1 on one of its main faces, designated by the underside. The beam is further provided with flanges 2 formed on the ridges between the lower face and the two other adjacent main faces, said flanges 2 extending said face.

   lower, and chamfers 3 formed on the two tres edges parallel to the aforementioned edges, said chamfers 3 intersecting the edges of the upper part of the beam parallel to the edges 2.



  To build the joist. the elements are placed one behind the other (fig. 3a, b, c ...) their channels 1 constituting a single channel which occupies the entire length of the beam. The channel 1 is filled with cement 5 by embedding in the mass of this cement a reinforcing iron whose ends protrude outside the vertical planes limiting each of the end elements of the beam.



  Edges 2 have. for goal. prevent that when the joists are placed side by side, in order to constitute a floor, their vertical facings do not come into contact with each other, but rather that the edges 2 come into contact, so that there is a channel between the two beams, the bottom of which is formed by the union of the deiLx edges.
