Abstract

The invention concerns a clamp for fixing pipework. This clamp which is characterised in that the two half clamps 1 and 2 which constitute it are assembled by self aligning captive screws 3, respectively by mounting in an oblong hole 4 and by the intermediary of a cut off 3a which is made under the head. These screws 3, which may be self tapping or standard, are fixed into smooth holes or helical holes, made in the lugs of the stationary half clamp 1. The clamp, according to the invention, is mainly intended for fixing, to a wall, rainwater down pipes or pipes for the general transport of fluid.

Description

La présente invention concerne les colliers de fixation de tuyauteries de descente d'eaux pluviales et analogues. The present invention relates to clamps for fixing downpipes for rainwater and the like.

Ces colliers sont constitués en deux parties réalisées en feuillard nervuré ou en fer plat, généralement assemblées par vis et écrou. Ce moyen d'assemblage, bian que très classique, présente cependant l'inconvénient de compliquer la mise en place des tuyauteries, car il nécessite un alignement parfai#t de celles-ci par rap port au demi-collier fixe, afin d'obtenir la superposition précise des trous de passage des vis, et oblige l'opérateur à utiliser deux clés pour effectuer le serrage. These collars are made up of two parts made of ribbed strip or flat iron, generally assembled by screw and nut. This means of assembly, bian that very conventional, however has the disadvantage of complicating the installation of the pipes, because it requires perfect alignment of these relative to the fixed half-collar, in order to obtain the precise overlapping of the screw passage holes, and obliges the operator to use two wrenches to perform the tightening.

S'ajoutent à ceci les risques de perte devis et des écrous au cours des manipulations et l'obligation d'utiliser les deux mains; ce qui compromet la sécurité lorsque le travail doit s'effectuer à partir d'une échelle. Added to this is the risk of losing quotes and nuts during handling and the obligation to use both hands; which compromises safety when work has to be done from a ladder.

Différentes solutions ont déjà été imaginées et réalisées pour remédier aux inconvénients précédemment mentionnés. Parmi ceux-ci, on peut citer celui décrit dans le brevet français NO 2.174.351 du 23 Février 1972, lequel consiste principalement à utilisera comme moyen de fixation des demi-colliers, un système de languettes replis ables et de boutonnières.Cette solution, bien qu'éliminant les ris ques de perte des vis et des écrous et supprimant l'emploi de clés de serrage, laisse cependant subsister ltobligåtion d'aligner de fa çon précise les deux demi-colliers7 pour permettre l'introduction des languettes dans les boutonnières; or il arrive fréquemment qu' un certain désalignement existe entre le demi-collier fixe et la tu yauterie, lequel doit être,en conséquence,compensé par an certain décalage des deux demi-colliers l'un par rapport à l'autre. Different solutions have already been devised and implemented to remedy the drawbacks mentioned above. Among these, there may be mentioned that described in French Patent No. 2,174,351 of February 23, 1972, which mainly consists in using as a means of fixing the half-collars, a system of foldable tabs and buttonholes. although eliminating the risk of loss of screws and nuts and eliminating the use of tightening wrenches, however, there remains the obligation to precisely align the two half-collars7 to allow the introduction of the tabs in the buttonholes ; now it frequently happens that a certain misalignment exists between the fixed half-collar and the pipe fitting, which must therefore be compensated for by a certain offset of the two half-collars with respect to each other.

Le collier de fixation selon l'invention combine les avantages de ceux à assemblage par vis et écrous et de ceux à assemblage par languettes et boutonnières tout en se pretant à l'automatisation du montage au conditionnement. The fixing collar according to the invention combines the advantages of those with assembly by screws and nuts and those with assembly by tabs and buttonholes while lending itself to automation from assembly to packaging.

Ce collier de fixation se caractérise principalement en ce que les deux demi-colliers qui le constituent sont assemblés par des vis auto-alignables et imperdables. This fixing collar is mainly characterized in that the two half-collars which constitute it are assembled by self-aligning and captive screws.

Les vis sont rendues imperdables par l'intermédiaire d'un décolletage réalise sous la tête. Elles sont rendues auto-alignables par leur montage dans un trou oblong, disposé perpendiculairement à l'axe de la tuyauterie, dont les bords pénètrent dans le décolletage.  The screws are made captive by means of a bar turning made under the head. They are made self-alignable by their mounting in an oblong hole, arranged perpendicular to the axis of the piping, the edges of which penetrate into the turning.

L'assemblage des deux demi-colliers est obtenu par vissage de vis auto-taraudeuses dans des trous lisses, de diamètre approprié, préalablement percés dans les pattes du collier fixe. The assembly of the two half-collars is obtained by screwing self-tapping screws in smooth holes, of appropriate diameter, previously drilled in the legs of the fixed collar.

Selon une variante, l'assemblage des deux demi-colliers est obtenu par vissage de vis standard dans des trous hélicotdaux obtenus par emboutissage. According to a variant, the assembly of the two half-collars is obtained by screwing standard screws into helical holes obtained by stamping.

D'autres caractéristiques et avantages apparaitront dans la description qui va suivre d'un collier de descente d'eau, réalise selon l'invention? donné à titre d'exemple non limitatif, au regard du dessin annexé, sur lequel
- La figure I représente une vue d'ensemble du collier, en perspective cavalière.Other characteristics and advantages will appear in the following description of a water descent collar, produced according to the invention? given by way of nonlimiting example, with regard to the appended drawing, in which
- Figure I shows an overview of the collar, in perspective perspective.

- La figure 2 représente une vue de face partielle du collier mobile, montrant la disposition du trou oblong. - Figure 2 shows a partial front view of the movable collar, showing the arrangement of the oblong hole.

- La figure 3 représente une coupe transversale partielle du collier équipe de vis auto-taraudeuses. - Figure 3 shows a partial cross section of the collar team of self-tapping screws.

- La figure 4 représente une coupe transversale partielle du collier équipé de vis normales standardsvissées dans des trous hd Oc tdaux.  - Figure 4 shows a partial cross section of the collar fitted with standard normal screws screwed into holes hd Oc tdaux.

Selon les figures I, 2, 3 et 4, le collier est constitué essentiellement du demi-collier fixe I, dans les pattes duquel le trou lisse 5 est percé ou le trou hélicotdal 6 est embouti, du demi-collier amovible 2, dans les pattes duquel est découpé le trou oblong 4, et des vis 3, standardsou auto-taraudeuses. According to Figures I, 2, 3 and 4, the collar consists essentially of the fixed half-collar I, in the legs of which the smooth hole 5 is drilled or the helical hole 6 is stamped, of the removable half-collar 2, in the legs from which the oblong hole 4 is cut, and screws 3, standard or self-tapping.

En se reportant à nouveau à l'ensemble des figures, on remarque que les vis 3 sont retenues au collier amovible 2 par l'intermédiaire d'un décolletage 3a, réalisé sous la tête de la vis, dans lequel pénètrent les bords du trou oblong 4; étant entendu que la lar
geur du trou oblong est légèrement inférieure au diamètre de la vis.Referring again to all of the figures, it is noted that the screws 3 are retained with the removable collar 2 by means of a turning 3a, produced under the head of the screw, into which the edges of the oblong hole penetrate. 4; it being understood that the lar
The size of the oblong hole is slightly less than the diameter of the screw.

Cette réduction de largeur du trou oblong est obtenue par déformation permanente suite à un serrage transversal des pattes apres mise en place de la vis 3, afin de rendre celle-ci définitivement prison niera. This reduction in width of the oblong hole is obtained by permanent deformation following a transverse tightening of the tabs after the screw 3 has been put in place, in order to make the latter definitively prison.

Un autre mode de montage des vis consiste à introduire cellesci à force dans les trous oblongs dont la largeur est, de fabrica tionolégèrement inférieure au diamètre des vis 3, en jouant sur la déformation élastique du métal. Another method of mounting the screws is to force them into the oblong holes, the width of which is slightly less than the diameter of the screws 3, by varying the elastic deformation of the metal.

Les trous lisses ou hélicotdaux sont percés ou emboutis dans les pattes du collier fixe I, de façon à leur faire jouer un rôle d' écrou, selon que l'on utilisera respectivement une vis auto-tarau deuse ou une vis standard. The smooth or helical holes are drilled or stamped in the legs of the fixed collar I, so as to make them play the role of nut, depending on whether a self-tapping screw or a standard screw is used respectively.

Ainsi, comme on le voit le demi-collier 2 pourra etre fixé au demi-collier I avec un certain décalage latéral par rapport à celuici, dans la latitude offerte par les trous oblongs 4; ceci pour tenir compte d'un décalage axial de la tuyauterie par rapport au demicollier I, préalablement fixé à la paroi, ou d'une déformation de la tuyauterie. Il arrive ,en effet que, malgré toutes les précautions, les demi-colliers I ne soient pas parfaitement alignés lors de leur fixation a la paroi ou que la tuyauterie soit déformée longitudina lement ou transversalement. Thus, as can be seen, the half-collar 2 can be fixed to the half-collar I with a certain lateral offset relative to that, in the latitude offered by the oblong holes 4; this is to take account of an axial offset of the piping relative to the semi-clamp I, previously fixed to the wall, or of a deformation of the piping. It happens, in fact that, despite all the precautions, the half-collars I are not perfectly aligned when they are fixed to the wall or that the piping is deformed longitudinally or transversely.

Quant à la solidarisation définitive des vis 3 par rapport au demi-collier 2 et à l'absence d'écrou, on imagine aisément qu'ils excluent tout risque de perte ou de tatonnement et qu'ils renforcent la sécurité puisqu'unie seule main est nécessaire pour serrer #les vis 3. As for the final connection of the screws 3 with respect to the half-collar 2 and the absence of nut, it is easy to imagine that they exclude any risk of loss or groping and that they reinforce security since they are united with one hand is necessary to tighten #the screws 3.

Le collier selon l'invention est destiné principalement à la fixation des tuyauteries de descente d'eau pluviale, mais son usage peut être étendu à la fixation contre une paroi de canalisation de transport de fluide.  The collar according to the invention is intended mainly for fixing rainwater descent pipes, but its use can be extended to fixing against a wall of fluid transport pipe.
