Abstract

The clamp is used for interconnecting strap parts, as are used in scaffolding or the like. It consists of two half bodies (1) which can be attached by means of bolts (6) and nuts (7) to a strap in the form of a tubular profile part or a similar profile part which, however, has the same clamping profile. Projections (4), which are provided on the connecting plane of the two half bodies, penetrate at one point (9) into the profile part, without the clamping force of the bolts (6) and nuts (7). The clamp can be matched to the desired alignment of lateral reinforcing supports. The clamp is used, for example, for the suspension of overhead conveyors and their auxiliary devices, platforms, catwalks, safety devices and the like.

Description

La presente invention s'applique a une bride pour l'assemblage de membrures en forme d'equerres, de plats ou de tubes qui doivent être rattachés entre eux de maniere solide telles qu'utilisées pour les échafaudages et autres structures assimilables. The present invention applies to a flange for the assembly of frames in the form of angles, plates or tubes which must be attached to each other in a solid manner as used for scaffolding and other assimilable structures.

Cette bride doit permettre en particulier l'accrochage de convoyeurs aeriens, passerelles, panneaux de sécurité et autres installations dans des bati -ments existants. This flange must in particular allow the hanging of overhead conveyors, gangways, safety panels and other installations in existing buildings.

Le but de cette invention est d'obtenir un dispositif servant à raccorder ensemble différentes membrures et qui ne soit pas seulement robuste et solide, mais qui permette en plus un montage simple et à n'importe quel endroit le long de l'élément tubulaire de la construction. De plus, cette bride devrait pouvoir être fabriquee industriellement et à bon marche. The object of this invention is to obtain a device which is used to connect different members together and which is not only robust and solid, but which also allows simple mounting and anywhere along the tubular element. construction. In addition, this flange should be able to be manufactured industrially and inexpensively.

Il existe déjà des brides ne présentant pas de profil de serrage qui épouse la forme du tube. Ce profil adapté à la forme du tube est cependant nécessaire pour des raisons de securité, car ces membrures de construction devaient jusqu'à present être en plus assurées par des perçages. There are already flanges that do not have a tightening profile that matches the shape of the tube. This profile adapted to the shape of the tube is, however, necessary for safety reasons, since these construction members have hitherto had to be additionally provided by drilling.

Ces avantages sont obtenus dans la bride objet de l'invention, suivant laquelle on a deux corps de bride identiques l'un sur l'autre de manière à permettre le serrage d'un tube, ou d'une pièce ayant une autre forme, entre eux. These advantages are obtained in the flange which is the subject of the invention, according to which there are two identical flange bodies one on the other so as to allow the clamping of a tube, or of a part having another shape, between them.

La tension de serrage sur les surfaces de contact est obtenue au moyen des vis et des écrous qui sont introduits dans les perçages à travers les deux corps de bride.The clamping tension on the contact surfaces is obtained by means of the screws and nuts which are introduced into the holes through the two flange bodies.

Sur les surfaces de serrage, se trouvent des bossages acérés. Ceux-ci pénètrent dans la pièce à serrer (tube) quand on bloque les vis. Les dimensions des bossages et leur position en biais dans le sens de la poussée garantissent quela pièce à serrer soit deformee de maniere permanente mais définie et qu'ainsi l'on ait en plus d'un blocage par friction de la bride, un maintien par in- crustation. On serre les vis et les ecrous jusqu'à ce que les deux surfaces de contact des corps de brides trouvent l'une sur l'autre et que les vis soient precontraintes dans le sens de leur.moment de torsion. There are sharp bosses on the clamping surfaces. These enter the part to be tightened (tube) when the screws are blocked. The dimensions of the bosses and their biased position in the direction of the thrust guarantee that the part to be clamped is permanently deformed but defined and that in this way there is in addition to a friction blocking of the flange, a maintenance by inlay. The screws and nuts are tightened until the two contact surfaces of the flange bodies are on top of each other and the screws are prestressed in the direction of their torque.

D'autres profilés ou bien d'autres pièces de construction peuvent être boulonnées ou raccordées d'autre manière au moyen de cette bride.  Other profiles or other construction parts can be bolted or otherwise connected using this flange.

La description suivante d'un exemple de réalisation-type d'un assemblage permet, en se référant aux plans ci-joints, ded,- couvrir les autres caractéristiques et avantages de l'invention. The following description of a typical embodiment of an assembly makes it possible, with reference to the attached plans, to cover the other characteristics and advantages of the invention.

La figure i montre une bride décompose par pièces dans une représentation en perspective. Figure i shows a flange broken down into pieces in a perspective representation.

La figure 2 montre un exemple de réalisation d'un noeud pour l'accrochage d'un rail de convoyeur aérien. Figure 2 shows an exemplary embodiment of a node for the attachment of an overhead conveyor rail.

Sur le plan représenté en Fig. 1, on peut voir que la bride est constituée de 2 demi-corps (1) avec des perçages (2). De la surface de. serrage en arc de cercle (3) sortent des bossages de forme acérée (4). La bride (t) est dimensionnée de manière à pouvoir supporter et transmettre des forces. La surface de serrage (3) peut avoir aussi une autre forme que celle en arc de cercle. On the plan shown in Fig. 1, it can be seen that the flange consists of 2 half-bodies (1) with holes (2). From the surface of. tightening in an arc (3) come out of the sharp-shaped bosses (4). The flange (t) is dimensioned so as to be able to support and transmit forces. The clamping surface (3) can also have a shape other than that of an arc of a circle.

Pour réaliser un bridage, on place deux demi-corps, comme représenté sur la figure 1 autour d'un tube (5). To achieve a clamping, two half-bodies are placed, as shown in Figure 1 around a tube (5).

Les vis (6) et écrous (7) serrent les deux demi-corps (1) l'un contre l'autre, qui, après serrage, se touchent par les surfaces (8). Quand on serre, les bossages (4) s'incrustent dans le tube et le déforment de manière permanente (9). The screws (6) and nuts (7) tighten the two half-bodies (1) against each other, which, after tightening, touch each other by the surfaces (8). When tightened, the bosses (4) become embedded in the tube and permanently deform it (9).

Les vis doivent être calculées de manière àce que la limite d'étirage ne soit pas dépassée par action de la force de déformation. The screws must be calculated so that the stretch limit is not exceeded by the action of the deformation force.

La pièce support (io) de forme quelconque est fixée par les mêmes vis (6) et écrous (7) à la bride. The support piece (io) of any shape is fixed by the same screws (6) and nuts (7) to the flange.

Le dessin ne représente pas une variante, dans laquelle la pièce support est collée à la bride (i) ou fixée d'une autre manière, mais on en conçoit la possibilité. The drawing does not represent a variant, in which the support piece is glued to the flange (i) or fixed in another way, but we can imagine the possibility.

La figure 2 représente un exemple de réalisation d'un noeud pour l'accrochage d'un convoyeur aérien. La pièce support (lO) (dans notre exemple, une plaque) est fixée solidement aux profiles de la charpente du bâtiment ou aux autres pièces de construction. Le tube accroché (5) pris en exemple est fixé au moyen de la bride (1), vis (6) et ecrous (7) à la pièce support comme indiqué sur la figure 1. Les extrémités du tube (5) sont limitées par des contre-plaques (12). Ces contre-plaques sont nécessaires pour des raisons de sécuråté, pour limiter un glissement du bridage en cas de montage défectueux.  FIG. 2 represents an exemplary embodiment of a node for the attachment of an overhead conveyor. The support piece (10) (in our example, a plate) is securely attached to the profiles of the building frame or to the other construction pieces. The hooked tube (5) taken as an example is fixed by means of the flange (1), screws (6) and nuts (7) to the support part as shown in Figure 1. The ends of the tube (5) are limited by counter plates (12). These counter plates are necessary for safety reasons, to limit slippage of the clamping in the event of defective mounting.

On a aussi une traverse en cornière (11) fixée au tube au moyen de corps de bride (1). A cette traverse est vissée une griffe de serrage (13) qui porte le rail de roulement (14) d'un convoyeur aérien. There is also an angle crosspiece (11) fixed to the tube by means of flange body (1). A clamping claw (13) which carries the running rail (14) of an overhead conveyor is screwed to this cross member.

On peut modifier la distance entre la traverse (li) et la charpente du bâtiment (représentée ici par un profilé en U (15) grâce à la longueur appropriée du tube. You can change the distance between the crosspiece (li) and the building frame (represented here by a U-shaped profile (15) thanks to the appropriate length of the tube.

Le sens de la charpente (15) par rapport à l'orientation du rail du convoyeur est indifférent, parce que les corps de brides sur le tube peuvent être orientés à volonté. The direction of the frame (15) relative to the orientation of the conveyor rail is immaterial, because the flange bodies on the tube can be oriented at will.

On peut donc fixer d'autres traverses, etc... au tube au moyen des brides à n'importe quel endroit et dans n'importe quelle direction. It is therefore possible to fix other crosspieces, etc. to the tube by means of the flanges at any place and in any direction.

Le serrage en épousant la forme du tube permet de compenser facilement des tolérances de construction qui existent à certains endroits, puisque l'on n'a pas besoin de renouveler les perçages, comme cela doit se faire pour les bridages avec vis traversantes. On peut réajuster facilement les écarts de hauteur. Tightening by matching the shape of the tube makes it easy to compensate for the construction tolerances that exist in certain places, since there is no need to renew the holes, as must be done for clamping with through screws. Height differences can be easily readjusted.

On peut par exemple, définir le tube sans même avoir un plan définitif.We can for example define the tube without even having a final plan.

Pour la fabrication et la commande, on dispose de plus de temps, on peut aussi avoir des lots de fabrication plus importants. For manufacturing and ordering, we have more time, we can also have larger manufacturing batches.

La réalisation selon l'invention est simple et bon marché. The production according to the invention is simple and inexpensive.

L'invention décrite peut être modifiée en plusieurs aspects, sans pour autant sortir de son cadre. Ainsi les tubes ronds pourraient par exemple avoir une autre forme, ou bien les brides de serrage pourraient être intégrées dans d'autres parties de construction ou avoir d'autres formes. De plus, tous les autres éléments peuvent être remplacés par des pièces aux carac téristiques techniques équivalentes et les matériaux et dimensions utilisés, choisis en fonction des besoins.  The invention described can be modified in several aspects, without going beyond its ambit. Thus the round tubes could for example have another shape, or else the clamps could be integrated into other construction parts or have other shapes. In addition, all the other elements can be replaced by parts with equivalent technical characteristics and the materials and dimensions used, chosen according to needs.
