Abstract

Device for using rapid fasteners on a composite I-beam. It is made up of a corrugated metal sheet 1 driven into the wooden components 2 using a press, with wedges 3 for tubes 4 by means of rapid fasteners 5-6. The device according to the invention makes it possible to reinforce composite I-beams.

Description

La présente addition & la demande de brevet d'invention n 85 07340 du 13/5/85 et ses additions n 1 - 85 11841 du 31/7/851 n 2 85 14169 du 23/9/85 concerne des attaches rapides utilisées sur une nouvelle poutre composite en I. The present addition to patent application No. 85 07340 of 5/13/85 and its additions No. 1 - 85 11,841 of July 7, 851 No. 2 85 14,169 of September 23, 85 concerns quick couplers used on a new composite I-beam.

Il existe des poutres faites d'une tôle ondulée centrale à ondulations verticales enfoncées å la presse dans deux bois rectangulaires formant ainsi des poutres en I. There are beams made of a central corrugated sheet with vertical undulations pressed in the press in two rectangular woods thus forming I-beams.

oN peut les renforcer d'une façon simple en fixant par paires sur et sous ces poutres, soit des tubes ordinaires, soit des tubes à nervures intérieures, soit score des bambous s cette fixation se faisant au moyen de doubles ceintures métalliques ou en cordage. We can reinforce them in a simple way by fixing in pairs on and under these beams, either ordinary tubes, or tubes with internal ribs, or score bamboos s this fixing being done by means of double metallic belts or rope.

Le dispositif représenté sur les figures 1 & 2 montre cette poutre en I faite dans sa partie centrale d'une tôle ondulée (1) à ondulations verticales enfoncée à la presse dans deux bois rectangulaires (2) en lamellé colle si nécessaire avec chacun une butée (3) de section rectangulaire ou triangulaire cloués ou collés sur et sous les bois (2). Cette butée sert de cale à quatre tubes (4 ou 4A) (à nervures internes) posés deux par deux ou trois par trois sur et sous cette poutre. Les fixations de ces tubes par paires se font au moyen d'une double ceinture passée à travers la tôle (1) autour des bois (2) et tubes (4 ou 4A).En fig. 3 cette ceinture est faite d'un cable simple (5) traversant dans son milieu un manchon de section tubulaire (6) ou mieux de section triangulaire à angles arrondis (6A); les extrémités de ce cable (5) sont ramenées dans ce manchon (6 ou 6A) avant sertissage, pour former un trajet en forme de 8 autour des bois (2 & 3) et tubes (6 6A). Une fois serti, le manchon (6A) reprend une section de forme circulaire. Cette double ceinture peut aussi etre faite d'un cordage (7) à noeud simple d'extrémités passant deux fois dans une rondelle (8) (ou manchon rainuré intérieurement, ou mEme d'un écrou) pour se fixer sur le côté de la poutre en effectuant aussi un trajet en forme de 8 avec axe d'arret (9) à travers ce cordage. On renforce encore cette poutre en fixant des panneaux (10) contre ou entre les bois (2). The device shown in Figures 1 & 2 shows this I-beam made in its central part of a corrugated sheet (1) with vertical undulations pressed in the press in two rectangular woods (2) in glulam if necessary with each a stop (3) of rectangular or triangular section nailed or glued on and under the woods (2). This stop serves as a wedge for four tubes (4 or 4A) (with internal ribs) placed two by two or three by three on and under this beam. The attachments of these tubes in pairs are made by means of a double belt passed through the sheet (1) around the woods (2) and tubes (4 or 4A) .In fig. 3 this belt is made of a single cable (5) passing through its middle a sleeve of tubular section (6) or better of triangular section with rounded angles (6A); the ends of this cable (5) are brought back into this sleeve (6 or 6A) before crimping, to form an 8-shaped path around the woods (2 & 3) and tubes (6 6A). Once crimped, the sleeve (6A) takes up a circular section. This double belt can also be made of a cord (7) with a single knot of ends passing twice through a washer (8) (or sleeve grooved internally, or even with a nut) to be fixed on the side of the beam by also performing an 8-shaped path with a stop pin (9) through this rope. This beam is further reinforced by fixing panels (10) against or between the woods (2).

Le dispositif selon l'invention est destine a réaliser des poutres en I, en bois, en bambou, avec tubes métalliques ou plastiques. The device according to the invention is intended to produce I-beams, made of wood, bamboo, with metal or plastic tubes.

Claims

1) Device according to claim 1 of patent application No. 85 07340 of 15/8 and its additions No. 1.85.11841 of 7/31/85, No. 2

and27 of 3/3/86 - 85 14,169 of 9/23/85 concerning quick couplings c'aradtérisés in that they allow to create a new composite beam in I comprising a central sheet (1) pressed in the press in two rectangular upper and lower wood (2) in glued laminate if necessary with each a longitudinal stop (3) (rectangular or triangular) optional nailed or glued to wedge two or three tubes or bamboo (4) or internally ribbed tubes (4A) on and under this beam), all the 4 - 4t tubes being in glued laminate if necessary.

2) Device according to claim 1 characterized in that the double fastening belts of these tubes (4 k 4A) around the woods (2 & 3) (glued laminated if necessary) through the corrugated sheet (î) are made t either of a metallic cable (5) passing through its sleeve a tubular (6) or triangular section with rounded angles (6A), the cable ends (5) of which are brought back into the sleeve (6 or 6A) before crimping for follow an 8-shaped path around and through the sheet or wood (2 & 3) and tubes (6, 6A). Once crimped, molded or welded, the sleeve 6A takes on a circular section. Or again this double belt is made of a braided cord (7) with simple end stop knots or a cable (5 ) passing twice or crossing in a washer (8) or sleeve (grooved internally) crimped, molded or welded, or even with a nut, to be fixed on the side of the beam by also carrying out a path in the shape of 8 with stop pin (9) through this rope. These latter belts allow three triangular tubes to be assembled on and under the beam twice.

3) Device according to claim 1 characterized in that this beam is further reinforced either by fixing panels or flanks of glued laminated (10) against or between the woods (2), or by making its elements interchllangebles including by putting instead of sheet 1 #unbois 2 in laminated2Hressé and using the appropriate quick couplers whatever their position in relation to each other and whatever their angle of opening.

4) Device according to claims 1 2 3 characterized in that the sheet or wood 1 - 2 - 3 can be replaced by a profile uni o that I or ET or be made of different composite materials.

5) Device according to claims 1 to 4 characterized in that the fire resistance of this beam is replaced by a liquid circulation tube for automatic fire extinction.

6) Device according to claims 1 to 5 characterized in
