Collier multidirectionnel pour échafaudages tubulaires en aluminium. Multidirectional clamp for tubular aluminum scaffolding.
La présente invention concerne un collier réalisé à l'aide de deux pièces jumelles emboîtées autour d'un tube et serrées par translation, destinée à la fabrication d'échafaudages multiniveaux et multidirectionnels en aluminium. The present invention relates to a collar produced using two twin pieces fitted around a tube and tightened in translation, intended for the manufacture of multilevel and multidirectional aluminum scaffolding.
On connaît des réalisations d'échafaudages en aluminium dont les éléments de jonction sont soudés, ces éléments présentent l'inconvénient occasionné par les soudures, celles ci affaiblissent le métal par brûlure, qui devient impropre à supporter les charges lourdes. Are known embodiments of aluminum scaffolding whose junction elements are welded, these elements have the drawback caused by the welds, these weaken the metal by burning, which becomes unfit to support heavy loads.
Ce collier fixé par serrage sur poteaux d'échafaudages en aluminium supprime cet inconvénient. Il permet de recevoir pour assemblage les extrémités pourvues de chapes et clavettes des éléments horizontaux ou obliques selon toutes directions. This clamp fixed by clamping on aluminum scaffolding poles eliminates this drawback. It allows to receive for assembly the ends provided with yokes and keys horizontal or oblique elements in all directions.
Ce collier est réalisé par l'assemblage de deux pièces jumelles obtenues par tronçonnage, à la longueur désirée, d'un seul profilé. This collar is produced by assembling two twin parts obtained by cutting, to the desired length, from a single profile.
Chaque demi pièce comporte à une extrémité une partie femelle en forme de mortaise et, à l'extrémité opposée une partie mâle en forme de tenon, assemblées elles constituent le collier. Each half-piece has at one end a female part in the shape of a mortise and, at the opposite end a male part in the shape of a tenon, assembled they constitute the collar.
Ce collier comporte les conditions de réception et fixation des éléments horizontaux ou obliques composant un échafaudage. This collar includes the conditions for receiving and fixing the horizontal or oblique elements making up a scaffold.
Selon l'invention, l'assemblage des deux demi pièces se fait en les positionnant face à face et tête bêche autour d'un tube et en faisant glisser latéralement les tenons dans les According to the invention, the two half pieces are assembled by positioning them face to face and head to tail around a tube and by sliding the pins laterally in the

mortaises, le tenon d'une demi pièce entrant dans la mortaise de l'autre. mortises, the tenon of a half piece entering the mortise of the other.
Selon ce dispositif le collier est formé autour d'un tube et le ceinture parfaitement. According to this device, the collar is formed around a tube and the belt perfectly.
L'ensemble tube et collier est percé afin de recevoir un boulon traversant diamétralement pour serrage. Ce perçage est d'un diamètre supérieur à celui du boulon afin de permettre la translation. The tube and collar assembly is drilled in order to receive a bolt passing diametrically for tightening. This hole has a diameter greater than that of the bolt to allow translation.
Selon le dispositif, lors du serrage du boulon traversant, les pentes en contact des tenons dans les mortaises glissent sur elles-mêmes, provoquant un rapprochement centripète des deux demi pièces. According to the device, when tightening the through bolt, the slopes in contact with the tenons in the mortises slide on themselves, causing a centripetal bringing together of the two half pieces.
Selon le dispositif le boulon n'offre aucune saillie susceptible de gêner la fixation des horizontales et des diagonales. According to the device, the bolt does not offer any projection liable to hinder the fixing of the horizontal and diagonal lines.
Les dessins annexes illustrent l'invention La figure 1 représente une vue en plan du profilé duquel est extrait, par tronçonnage, une pièce B avec en n 7 et no 7bis les faces externes servant d'appuis aux éléments
horizontaux ou obliques, et avec en no S et en nabis les espaces libres pour passage des clavettes de serrage.. The accompanying drawings illustrate the invention. FIG. 1 represents a plan view of the profile from which a part B is extracted, by sectioning, with in n 7 and no 7bis the external faces serving as supports for the elements
horizontal or oblique, and with no S and nabis free spaces for passage of the clamping keys.
La Figure 2 représente deux pièces B positionnées tête bêche et face à face sur un tube la, après emboîtement des tenons 9 dans les mortaises par glissement latéral. En X sont représentés les espaces disponibles pour permettre la translation lors du serrage de l'ensemble par boulon. Figure 2 shows two pieces B positioned head to tail and face to face on a tube la, after interlocking of the pins 9 in the mortises by lateral sliding. In X are shown the spaces available to allow translation when tightening the assembly by bolt.
La figure 3 représente les deux pièces B positionnées et boulonnées. Selon cette figure, lors du serrage du boulon 6 Figure 3 shows the two parts B positioned and bolted. According to this figure, when tightening the bolt 6

traversant diamétralement l'ensemble, les pentes 5 des tenons 9 en contact avec les pentes des mortaises réceptrices, glissent les unes sur les autres, et provoquent le rapprochement centripète des deux pièces B sur le tube 10. passing diametrically through the assembly, the slopes 5 of the tenons 9 in contact with the slopes of the receiving mortises, slide over one another, and cause the centripetal bringing together of the two parts B on the tube 10.
La figure 4 est une représentation du collier constitué de deux pièces B en position horizontale sur un poteau 10 avec, en tirets et pointillés, le type d'extrémité à fixation par clavetage des éléments horizontaux ou obliques 12. FIG. 4 is a representation of the collar made up of two parts B in a horizontal position on a post 10 with, in dashed and dotted lines, the type of end for fixing by keying horizontal or oblique elements 12.
Le collier d'assemblage pour échafaudage multidirectionnel tubulaire en aluminium permet la fixation rapide d'éléments horizontaux ou obliques en éliminant toute soudure. Pour cela, il est composé de deux demi colliers B et de moyens 6 pour les assembler suivant sensiblement un plan diamétral, les moyens pour assembler les deux demi colliers suivant sensiblement le plan diamétral étant constitués par deux emboîtements mâle-femelle 9 identiques, les deux extrémités planes d'un demi collier comportant respectivement la partie mâle 9 et la partie femelle d'un emboîtement associées respectivement à la partie femelle et à la partie mâle du même emboîtement portées par l'autre demi collier. Ces deux emboîtements mâle femelle identiques sont constitués par des emboîtements dits"en queue d'aronde". The assembly collar for multidirectional tubular aluminum scaffolding allows quick fixing of horizontal or oblique elements eliminating any welding. For this, it is composed of two half collars B and means 6 for assembling them substantially along a diametrical plane, the means for assembling the two half collars substantially along the diametrical plane being constituted by two identical male-female sockets 9, both flat ends of a half collar respectively comprising the male part 9 and the female part of a socket respectively associated with the female part and with the male part of the same socket carried by the other half collar. These two identical male female sockets consist of so-called "dovetail" sockets.
Le collier peut être fixé sur poteaux d'échafaudage permettant la fixation d'éléments horizontaux ou obliques à blocage par clavette selon quatre directions fixes à 900 selon les évidements 8, et à fixations orientables selon les évidements 8bis. Les deux demi colliers sont définis entre deux plans parallèles. The collar can be fixed on scaffolding posts allowing the fixing of horizontal or oblique elements with key locking in four directions fixed at 900 according to the recesses 8, and with orientable fixings according to the recesses 8bis. The two half collars are defined between two parallel planes.
Les emboîtements"en queue d'aronde"sont définis entre les deux plans et ont une épaisseur égale à l'épaisseur des deux demi colliers. The "dovetail" sockets are defined between the two planes and have a thickness equal to the thickness of the two half collars.
Chaque demi collier B, y compris ses deux parties d'emboîtement"en queue d'aronde"respectivement contenue et contenante, est obtenu d'une seule pièce par découpe d'un profilé. Each half collar B, including its two interlocking parts "dovetail" respectively contained and containing, is obtained in one piece by cutting a profile.
La présence de boulons 6 réunissant les deux pièces B ne gêne nullement l'utilisation du collier sur toute la périphérie nécessaire et en outre ce collier multidirectionnel n'est plus soudé sur les tubes poteaux. The presence of bolts 6 joining the two parts B in no way hinders the use of the collar over the entire periphery necessary and furthermore this multidirectional collar is no longer welded to the post tubes.
