  Eléments pour la construction de charpentes métalliques. 



   Ltinvention concerne un élément métallique pour la construction de.charpentes industrielles ou autres- Le plus   ! couramment,   qet élément est de forme triangulaire. Il est   compose   de barres convergeant vers des points de jonction dénommes, dans la présente description, noeuds d'assemblage. 



   Cet élément est spécialement   conçu   pour permettre la constitution d'éléments composites   de'   plus grandes dimensions, par l'assemblage l'un à la suite de l'autre d'éléments iden-   @   tiques, éventuellement orientés diversement. 



   Une particularité de l'invention consiste dans le fait que les barres de cet élément constituent des auges   dant   le plan. médian coïncide avec le plan médian de l'élément; le fond de ces' auges présentant une épaisseur sensiblement égale à celle de leurs parois, ¯Une autre partieularité de l'invention, éventuellementn indépendante de la précédente, consiste dans le fait que les noeuds, où se joignent les barres sont réalisés par embou- tissage et notamment par superposition et assemblage.de deux pièces embouties laissant entre elles un espace de largeur correspondant à la largeur des auges que constituent even- tuellement les barres-

  Elements for the construction of metal frames.



   The invention relates to a metallic element for the construction of industrial or other structures. commonly, this element is triangular in shape. It is composed of bars converging towards junction points called, in the present description, assembly nodes.



   This element is specially designed to allow the constitution of composite elements of larger dimensions, by the assembly one after the other of identical elements, optionally oriented differently.



   A feature of the invention consists in the fact that the bars of this element constitute troughs in the plane. median coincides with the median plane of the element; the bottom of these 'troughs having a thickness substantially equal to that of their walls, ¯ Another partieularity of the invention, possibly independent of the previous one, consists in the fact that the nodes, where the bars join, are made by embou- weaving and in particular by superposition and assembling. of two stamped parts leaving between them a space of width corresponding to the width of the troughs that possibly constitute the bars-

This is turned outwards, thus creating a trough at the periphery of each of these elements A and B.

   The stamped parts used to form knots and pre-threads can come from stamping of the same sheet and be of the same shape as the element to be produced by their superposition.
