Description

  

  <B>Poutre profilée en bois.</B>    La présenta invention a pour objet une  poutre profilée,     caractérisée    par le fait  qu'elle est constituée par-deux     demi-poutres     en forme de<B>U</B> assemblées au moyen de bou  lons, l'âme de l'une étant appliquée contre  l'âme de l'autre, de façon que leur juxtaposi  tion réalise une poutre dont la section a la  forme d'un double<B>T.</B>  



  Le dessin annexé montre, à titre d'exem  ple, une forme d'exécution de la poutre objet  de     l'invention.     



  La     fig.    1 en est une vue en coupe trans  versale, et  la     fig.    2 est une     vue-longitudinale    d'une  ferme en bois profilée, dont la section -est en  forme de double<B>T.</B>  



  La     poutre        représentée    à la     fig.    1 com  prend deux demi-poutres 1 et 2, comportant  des âmes 3 'et 4; chacune de celles-ci est cons  tituée par deux rangées 5 et 6 de planches;  les planches de chaque rangée 5 et 6 sont  juxtaposées, c'est-à-dire placées     jointivement     les unes à côté des     autres;    en     iutre,    les plan  ches de l'une des rangées sont superposées à  celles de l'autre;

   les     planches    d'une rangée  peuvent être fixées par collage ou par  clouage, ou encore par collage et clouage à  celles de la rangée     contiguë.    Les planches des  rangées 5 sont croisées par rapport à celles  des rangées 6 correspondantes, mais les plan  ches     des    deux rangées 5 sont inclinées dans  le même sens. '    Il est prévu     d'utiliser    et d'assembler des  planches     crétées    et rainurées pour constituer  une même rangée.  



  Les branches du<B>U</B> formé par les     demi-          poutres    1 et 2 sont constituées par des mem  brures 7 et 8, respectivement- 9 et 10. Les  membrures sont assemblées aux âmes 3 et 4  au moyen de clous ou de crosses 11, respecti  vement 12, dont les têtes, de même que celles  des clous assemblant les planches des rangées  5 et 6, sont logées à     l'intérieur    de l'âme de  la poutre en double<B>T.</B> Cette dernière est réa  lisée en assemblant, au moyen de boulons 13  et 14, les     demi-poutres    1 et 2. Cet assemblage  peut être réalisé à pied     d'oeuvre,    ce qui faci  lite le transport.  



  Les clous 11 et 12, de même que ceux re  liant les planches des rangées 5 et 6, n'étant  pas en     contact    avec l'air ambiant, ne se dété  riorent pas facilement.  



  Les     extrémités    de la poutre représentée  sur la     fig.    1 peuvent être munies de semelles  do     protection    15 et 16.  



  La poutre en double<B>T</B> représentée sur la       fig.    2 constitue une     demi-ferme    dont les       membrures    7 et 8 sont entretoisées à l'aide  de     montants    17, les deux demi-poutres qui la  constituent     étant        assemblées    au moyen de  boulons 11 et 13.  



  L'âme de la ferme comprend des planches  réparties en rangées 5 et 6, les planches des  deux rangées 5 étant parallèles entre elles et  inclinées dans le sens     longitudinal    par rap-           port    aux membrures, et forment avec les  planches     des    deux rangées 6 un angle d'en  viron 45 .  



  La poutre représentée à la     fig.    1 peut être  utilisée comme panne, sommier, etc.



  <B> Profiled wooden beam. </B> The present invention relates to a profiled beam, characterized by the fact that it consists of two half-beams in the form of a <B> U </B> assembled at the means of bolts, the web of one being applied against the web of the other, so that their juxtaposition forms a beam whose section has the shape of a double <B> T. </ B >



  The appended drawing shows, by way of example, one embodiment of the beam which is the subject of the invention.



  Fig. 1 is a cross-sectional view thereof, and FIG. 2 is a longitudinal view of a profiled wooden truss, the section of which is in the shape of a double <B> T. </B>



  The beam shown in fig. 1 com takes two half-beams 1 and 2, comprising webs 3 'and 4; each of these is constituted by two rows 5 and 6 of boards; the boards of each row 5 and 6 are juxtaposed, that is to say placed contiguously next to each other; in iutre, the planes of one of the rows are superimposed on those of the other;

   the boards of a row can be fixed by gluing or by nailing, or by gluing and nailing to those of the contiguous row. The boards of rows 5 are crossed with respect to those of the corresponding rows 6, but the boards of the two rows 5 are inclined in the same direction. 'It is planned to use and assemble crested and grooved boards to form a single row.



  The branches of the <B> U </B> formed by the half-beams 1 and 2 are formed by members 7 and 8, respectively- 9 and 10. The frames are assembled to webs 3 and 4 by means of nails or brackets 11, respectively 12, whose heads, as well as those of the nails assembling the boards of rows 5 and 6, are housed inside the web of the double beam <B> T. </ B > The latter is carried out by assembling, by means of bolts 13 and 14, the half-beams 1 and 2. This assembly can be carried out on the job, which facilitates transport.



  The nails 11 and 12, as well as those re binding the boards of rows 5 and 6, not being in contact with the ambient air, do not deteriorate easily.



  The ends of the beam shown in fig. 1 can be fitted with protective soles 15 and 16.



  The double <B> T </B> beam shown in fig. 2 constitutes a half-truss whose frames 7 and 8 are braced using uprights 17, the two half-beams which constitute it being assembled by means of bolts 11 and 13.



  The core of the truss comprises planks distributed in rows 5 and 6, the planks of the two rows 5 being parallel to each other and inclined in the longitudinal direction with respect to the frames, and forming an angle with the planks of the two rows 6 about 45.



  The beam shown in FIG. 1 can be used as a purlin, box spring, etc.
