POUTRE METALLIQUE DONT LES MONTANTS SONT ENROBES DANS DES
SEMELLES DE BOIS.METAL BEAM OF WHICH THE AMOUNTS ARE COATED IN
WOOD SOLE.
L'invention a pour objet une poutre légère particulièrement destinée à constituer l'ossature de murs et de charpentes de bâtiments, notamment de maisons.The invention relates to a light beam particularly intended to constitute the framework of walls and frames of buildings, in particular of houses.
On a déjà proposé, en particulier, dans FR-A-2 365 671 déposé le 23 Septembre 1977 au nom de KINDBERG Bengt Ake, de réaliser des poutres présentant des ailes en bois et une âme constituée par un fer ondulé ou en zigzag dont les zones de courbure sont fixées aux ailes.It has already been proposed, in particular, in FR-A-2 365 671 filed on September 23, 1977 in the name of KINDBERG Bengt Ake, to produce beams having wooden wings and a core constituted by a corrugated iron or zigzag whose areas of curvature are attached to the wings.
Dans ces poutres antérieures, les ailes en bois participent au travail de la poutre, si bien qu'elles doivent être suffisamment résistantes.In these anterior beams, the wooden wings participate in the work of the beam, so that they must be sufficiently resistant.
La fabrication de ces poutres est compliquée et onéreuse. En particulier, dans le mode d'exécution qui fait l'objet du brevet précité, où chaque aile comprend deux pièces de bois accolées entre elles munies d'évidements destinés à recevoir les zones de courbure, la réalisation de ces évidements est relativement onéreuse et l'opération de mise en place précise des zones de courbure dans les évidements est délicate. The manufacture of these beams is complicated and expensive. In particular, in the embodiment which is the subject of the aforementioned patent, where each wing comprises two pieces of wood joined together provided with recesses intended to receive the areas of curvature, the production of these recesses is relatively expensive and the operation of precise positioning of the zones of curvature in the recesses is delicate.
L'invention propose une poutre de réalisation simplifiée, dans laquelle les pièces de bois ne jouent que le rôle d'un simple enrobage de la partie métallique.The invention proposes a beam of simplified production, in which the pieces of wood only play the role of a simple coating of the metal part.
Suivant l'invention, une poutrelle métallique comprenant avantageusement une âme continue ondulée ou en zigzag telle que mentionnée ci-dessus ou constituée d'une pluralité d'éléments discrets et, en outre, deux fers longitudinaux fixés, avantageusement par soudage, aux points de courbure de l'âme ou aux extrémités des éléments discrets, a ses deux fers simplement encastrés et collés dans deux rainures longitudinales continues que présentent respectivement avantageusement, sur toute leur longueur, deux pièces de bois avantageusement monobloc constituant un habillage de la poutrelle métallique.According to the invention, a metal beam advantageously comprising a continuous corrugated or zigzag core as mentioned above or made up of a plurality of discrete elements and, in addition, two longitudinal irons fixed, advantageously by welding, at the points of curvature of the core or at the ends of the discrete elements, has its two irons simply embedded and glued in two continuous longitudinal grooves which advantageously have, over their entire length, respectively, two pieces of advantageously one-piece wood constituting a covering for the metal beam.
On décrira ci-après un exemple non limitatif de réalisation, en se référant au dessin annexé, dans lequel
La figure 1 représente un mode d'exécution préféré de
la poutrelle métallique
La figure 2 illustre l'assemblage de la poutrelle
métallique et des pièces de bois d'habillage
La figure 3 est une vue en coupe de la poutre complè
te
La figure 4 représente une variante d'exécution de la
poutrelle métallique ; et
Les figures 5 et 6 illustrent une autre variante où la
rainure est agencée pour recevoir une poutrelle dans
laquelle les points de courbure de l'âme viennent en
surépaisseur sur les fers.A nonlimiting exemplary embodiment will be described below, with reference to the appended drawing, in which
Figure 1 shows a preferred embodiment of
the metal beam
Figure 2 illustrates the assembly of the beam
metal and wood trim pieces
Figure 3 is a sectional view of the complete beam
you
FIG. 4 represents an alternative embodiment of the
metal beam; and
Figures 5 and 6 illustrate another variant where the
groove is arranged to receive a beam in
which the points of curvature of the core come in
extra thickness on the irons.
La poutre illustrée par les figures 1 à 3 comprend une poutrelle métallique composée de deux fers longitudinaux 1 et 2 réunis entre eux par une âme continue ondulée 4, avantageusement sinusoldale. The beam illustrated in Figures 1 to 3 comprises a metal beam composed of two longitudinal bars 1 and 2 joined together by a continuous wavy core 4, preferably sinusoldale.
Elle est par exemple réalisée en acier galvanisé, avec un écartement entre les fers de 140 ou 220 mm, les fers et l'âme ayant un diamètre de 4,5 à 10 mm. Les fers sont de préférence soudés sur l'amie aux sommets de la sinusoïde.It is for example made of galvanized steel, with a spacing between the irons of 140 or 220 mm, the irons and the core having a diameter of 4.5 to 10 mm. The irons are preferably welded on the friend at the tops of the sinusoid.
Dans la variante de la figure 4, l'amie est constituée par des barrettes soudées à leurs extrémités aux fers longitudinaux.In the variant of FIG. 4, the friend consists of bars welded at their ends to the longitudinal bars.
L'habillage de la poutrelle métallique est constitué par deux bois 5-6 de section carrée, par exemple de 50 mm de côté, vus en section droite aux figures 2 et 3, munis d'une rainure 50-60 sur toute leur longueur, avantageusement disposée dans un plan de symétrie du bois et ayant par -exemple une profondeur de 20 mm et une largeur légèrement inférieure au diamètre de l'acier de la poutrelle.The covering of the metal beam is formed by two woods 5-6 of square section, for example 50 mm on a side, seen in cross section in FIGS. 2 and 3, provided with a groove 50-60 over their entire length, advantageously arranged in a plane of symmetry of the wood and having for example a depth of 20 mm and a width slightly less than the diameter of the steel of the beam.
Comme le montre la figure 2, la poutrelle métallique est mise en place dans les rainures des bois pour réaliser l'assemblage, cette opération se faisant sans difficulté puisque les rainures sont continues. La fixation est assurée par collage. La rainure continue est très facile à réaliser.As shown in Figure 2, the metal beam is placed in the grooves of the wood to perform the assembly, this operation being done without difficulty since the grooves are continuous. The fixing is ensured by gluing. The continuous groove is very easy to make.
La forme de sa section pourra varier, en particulier pour s'adapter au cas où l'âme viendrait en surépaisseur sur les fers longitudinaux, comme l'illustrent les figures 5 et 6.The shape of its section may vary, in particular to adapt to the case where the core comes in excess thickness on the longitudinal bars, as illustrated in FIGS. 5 and 6.
Pour réaliser une telle rainure, il est commode dans ce cas de constituer le bois en deux moitiés assemblées entre elles par exemple par collage.To make such a groove, it is convenient in this case to constitute the wood in two halves assembled together for example by gluing.
I1 va de soi que de nombreuses formes d'exécution pourront être imaginées par l'homme du métier, sans s'écarter de l'esprit de l'invention. It goes without saying that many embodiments can be imagined by those skilled in the art, without departing from the spirit of the invention.
