Description

  

  Poutrelle en fer profilé.    Cette invention se rapporte<B>à</B> une pou  trelle en fer profilé pour des applications  diverses et plus spécialement pour la cons  truction de plafonds. Le profil choisi est, de  préférence, un profil<B>à</B> I<B>à</B> semelles larges,  c'est-à-dire dont les semelles ont une largeur  sensiblement égale<B>à</B> la hauteur de     l'I.    Sa  nouveauté réside en ce que l'âme de     l'I    est  plus mince que dans le profil normal et  garnie de nervures saillantes destinées<B>à</B>  conserver<B>à</B> l'âme ses qualités de résistance  et<B>à</B> créer des points d'adhérence pour le  béton ou mortier.  



  Le dessin annexé représente,<B>à</B> titre d'exem  ple, un profil et plusieurs vues de flanc de  différentes formes d'exécution de la poutrelle.  



  On remarquera que les poutrelles ont unie  forme de I dont les semelles<B>1</B> sont des  plaques à angles vifs auxquelles l'âme mé  diane 2 se raccorde par des arrondis<B>2'</B> pro  noncés.  



  L'épaisseur de l'âme 2 comparativement  <B>à</B> celle des profils ordinaires est réduite de    façon notable. En compensation, les flancs  de l'âme sont garnis de nervures saillantes 4  qui, dans la     fig.    2 forment, soit les losanges  adjacents se touchant par un coin, soit des  lignes conduites en     zig-zag.    Dans la     fig.   <B>3</B>  des échelons horizontaux 4' s'étendent en  plus alternativement en haut et en bas entre  les côtés des losanges.  



  Dans la     fig.    4, des nervures verticales 4"  sont disposées sur les flancs de l'âme<B>à</B> des  distances égales et entre deux nervures consé  cutives s'étendent des réseaux de deux ner  vures 4 disposées en diagonale.  



  Les nervures saillantes peuvent aussi être  disposées de manière<B>à</B> former des signes  graphiques (chiffres, lettres,     etc.)    destinés<B>à</B>  indiquer soit le calibre de la poutrelle, soit  la provenance,     etc.    Dans tout les cas, il  convient de les placer de manière qu'elles  procurent<B>à</B> l'âme de la poutrelle un maxi  mum de résistance contre tous les efforts  qu'elle aura<B>à</B> supporter quelle que soit leur  direction.



  Profiled iron beam. This invention relates to a profiled iron bin for various applications and more especially for the construction of ceilings. The profile chosen is preferably a profile <B> to </B> I <B> to </B> wide soles, that is to say whose soles have a width substantially equal to <B> to < / B> the height of I. Its novelty lies in that the core of the I is thinner than in the normal profile and furnished with protruding ribs intended <B> to </B> keep <B> to </B> the soul its qualities of resistance and <B> to </B> create points of adhesion for concrete or mortar.



  The appended drawing represents, <B> by </B> by way of example, a profile and several side views of different embodiments of the beam.



  It will be noted that the beams have a united I shape, the flanges <B> 1 </B> are sharp-angled plates to which the middle web 2 is connected by rounded <B> 2 '</B> pronounced .



  The thickness of the core 2 compared <B> to </B> that of ordinary profiles is significantly reduced. In compensation, the flanks of the core are lined with projecting ribs 4 which, in fig. 2 form either the adjacent diamonds touching each other by a corner, or zig-zag lines. In fig. <B> 3 </B> horizontal rungs 4 'additionally extend alternately up and down between the sides of the diamonds.



  In fig. 4, vertical ribs 4 "are arranged on the sides of the core <B> at </B> equal distances and between two consecutive ribs extend networks of two ribs 4 arranged diagonally.



  The projecting ribs can also be arranged in such a way <B> to </B> form graphic signs (numbers, letters, etc.) intended <B> to </B> indicate either the caliber of the joist or the origin, etc. In any case, it is advisable to place them so that they provide <B> to </B> the web of the joist a maximum resistance against all the forces that it will have <B> to </ B > support whatever their direction.
