Description

Bride d'assemblage, son procédé de fabrication, et pièces métalliques d'armature ou de charpente équipées d' une tel le bri de.Assembly flange, its manufacturing process, and metal parts of frame or frame equipped with such a bri.
La présente invention concerne une bride d'assem- blage. Elle vise également le procédé de fabrication de cette bride, ainsi que les pièces métalliques d'armatu¬ re ou de charpente, telles que pièces d'étayage ou de contreventement, consoles ou passerelles d'échafau¬ dages, etc., munies de cette bride. Actuellement, les brides de liaison équipant les pièces susmentionnées, sont réalisées simplement par emboutissage et pliage d'une bande rectangulaire décou¬ pée dans une tôle métallique d'épaisseur convenable, de manière à constituer une fourche comprenant un fond rectangulaire de longueur réduite et deux branches parallèles rattachées à ce fond et présentant une forme rectangulaire dont la largeur correspond à la longueur dudit fond. Un exemple d'exécution d'une telle bride ou fourche classique est illustré aux figures 1 à 3. Les brides de ce genre présentent, dans certaines applications, au moins deux inconvénients sérieux. Par exemp le, lorsque les brides équipent des éléments d'ar¬ mature ou de charpente destinés à occuper une position r goureusement horizontale et à être fixés sur des poutres perforées en bois et dressées verticalement, les inconvénients susmentionnés découlent du fait que le fond des brides ne plaque généralement pas étroi¬ tement contre le chant des poutres (un jeu étant, en effet, toujours prévu, en raison du gonflement possible du bois), de sorte que lesdites brides peuvent pivoter autour de leur axe de liaison (figure 3), d'où : - un défaut d'horizontalité des éléments d'armature ou de charpente plus ou moins important selon l'amplitude de l'angle α*1 de pivotement possible à partir de la position horizontale ; - un atriçage important du chant de la poutre, en raison du très fort couple appliqué par l'arête du bord inférieur du fond des brides sur ledit chant.The present invention relates to an assembly flange. It also relates to the method of manufacturing this flange, as well as the metal parts of reinforcement or frame, such as shoring or bracing parts, consoles or scaffolding gangways, etc., provided with this flange. Currently, the connecting flanges fitted to the above-mentioned parts are produced simply by stamping and folding a rectangular strip cut out of a metal sheet of suitable thickness, so as to constitute a fork comprising a rectangular bottom of reduced length and two parallel branches attached to this bottom and having a rectangular shape whose width corresponds to the length of said bottom. An example of execution of such a conventional flange or fork is illustrated in FIGS. 1 to 3. Flanges of this kind have, in certain applications, at least two serious drawbacks. For example, when the flanges are fitted with ar¬ mature or frame elements intended to occupy a r horizontally horizontal position and to be fixed on perforated wooden beams and erected vertically, the aforementioned drawbacks arise from the fact that the bottom of the flanges generally do not plate étroi¬ tement against the edge of the beams (a game being, in fact, always provided, due to the possible swelling of the wood), so that said flanges can pivot around their connecting axis (Figure 3) , hence: - a lack of horizontality of the reinforcing or framing elements more or less important depending on the amplitude of the angle α * 1 of possible pivoting from the horizontal position; - a significant drawdown of the edge of the beam, due to the very high torque applied by the edge of the lower edge of the bottom of the flanges on said edge.
On pourrait être tenté de remédier à ces inconvé¬ nients en réalisant des brides beaucoup plus larges et, par conséquent, dotées d'un fond sensiblement plus long, de manière à limiter l'amplitude de l'angle de pivotement possible, mais on aboutit, dans ce cas, à des pièces beaucoup plus lourdes qui ne favorisent pas la manutention, tandis que l'élargissement des branches des brides favorisent la torsion des angles de ces branches, sous L'effet des chocs auxquels elles sont exposées dans les conditions normales d'uti lisation des matériels de chantier, ce qui peut les rendre inuti lisables (en cas de déformation vers l'intérieur) ou constituer des risques d'accrochage et de blessure (en cas de déformation vers l'extérieur).We could be tempted to remedy these drawbacks by making much wider flanges and, consequently, provided with a substantially longer bottom, so as to limit the amplitude of the possible pivot angle, but we succeed , in this case, to much heavier parts which do not favor handling, while the widening of the branches of the flanges favor the twisting of the angles of these branches, under the effect of the shocks to which they are exposed under normal conditions of use of site materials, which can make them useless (in the event of deformation towards the interior) or constitute risks of snagging and injury (in the event of deformation towards the outside).
L'invention a notamment pour but de remédier à ces nconvénients.The object of the invention is in particular to remedy these drawbacks.
La bride selon l'invention comporte un fond et deux branches parallèles s'inscrivant dans des triangles isocèles dont la base est sensiblement plus grande que les côtés, ces branches étant rattachées audit fond par l'intermédiaire de leur base et étant pourvues de trous alignés pour le passage d'une broche de verroui llage ; cette bride étant encore remarquable par le fait que son fond présente une longueur beaucoup plus grande que la distance séparant l'axe de ses trous et la face interne dudit fond.The flange according to the invention comprises a bottom and two parallel branches inscribing in isosceles triangles whose base is substantially larger than the sides, these branches being attached to said bottom via their base and being provided with aligned holes for the passage of a locking pin; this flange being still remarkable in that its bottom has a length much greater than the distance separating the axis of its holes and the internal face of said bottom.
Selon le procédé de l'invention, on réalise d'abord un flan s'inscrivant dans un carré et découpé dans une tôle d'acier présentant une épaisseur convenable, et ce flan est ensuite plié le long de deux lignes espacées et parallèles à l'une des diagonales de ce carré, de manière à obtenir deux branches parallèles s'inscrivant dans un triangle isocèle. La bride comportant application de l'invention a notamment pour avantages :According to the method of the invention, a blank is first produced which is inscribed in a square and cut from a steel sheet having a suitable thickness, and this blank is then folded along two spaced lines parallel to the 'one of the diagonals of this square, so as to obtain two parallel branches inscribed in an isosceles triangle. The flange comprising application of the invention has in particular the advantages:
- une meilleure conservation de l'horizontalité des pièces horizontales d'armature ou de charpente équipées de cette bride, lorsque ces pièces sont fixées sur des poutres verticales ;- better conservation of the horizontality of the horizontal frame or frame parts equipped with this flange, when these parts are fixed on vertical beams;
- de permettre de fortes sollicitations de la bride sans matriçage de la poutre porteuse ;- to allow high stresses on the flange without stamping the supporting beam;
- d'obtenir les deux résultats intéressants ci-dessus sans augmentation de poids notable par rapport aux brides trad tionnelles.- Obtain the two interesting results above without significant increase in weight compared to traditional flanges.
Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesque Is :The aims, characteristics and advantages above, and others still, will emerge more clearly from the description which follows and from the appended drawings in which:

La figure 6 est une vue de face de La bride obtenue, après exécution des trous destinés au passage de L'axe de blocage et fixation sur une pièce d'armature métallique. Les figures 7 et 8 sont, respectivement, des vues de côté et de dessus de la figure 6. La figure 9 est une vue analogue à la figure 3 et permettant de comprendre Les avantages obtenus grâce à La bride selon l'invention.Figure 6 is a front view of the flange obtained, after execution of the holes for the passage of the locking pin and attachment to a piece of metal frame. Figures 7 and 8 are, respectively, side and top views of Figure 6. Figure 9 is a view similar to Figure 3 and for understanding the advantages obtained with the flange according to the invention.
On se reporte auxdits dessins pour décrire un exemple intéressant, mais non limitatif, de mise en oeuvre du procédé de fabrication et de réalisation de La bride selon L'invention.Reference is made to said drawings to describe an interesting, but nonlimiting example, of implementation of the method of manufacturing and making the flange according to the invention.
Selon ce procédé, un flan 1 s'inscrivant dans un carré, est d'abord découpé dans une tôle présentant l'épaisseur convenable, par exemple de l'ordre de 2,5 à 3mm.According to this method, a blank 1 inscribed in a square is first cut from a sheet having the appropriate thickness, for example of the order of 2.5 to 3mm.
Ce flan est, par exemple, avantageusement découpé suivant le profil illustré à la figure 4, c'est-à-dire avec des angles abattus.This blank is, for example, advantageously cut according to the profile illustrated in FIG. 4, that is to say with cut corners.
Le flan ainsi conformé est ensuite plié, à l'aide de tout procédé convenable, Le Long de deux Lignes 2 espacées et parallèles à L'une des diagonales 3 du carré, de manière à obtenir deux branches parallèles 4 s'inscrivant dans des triangles isocèles (figures 6 et 7) et rattachées, par leur base, à un fond 5 délimité par les lignes de pliage 2.The blank thus shaped is then folded, using any suitable method, along two lines 2 spaced apart and parallel to one of the diagonals 3 of the square, so as to obtain two parallel branches 4 inscribed in triangles isosceles (Figures 6 and 7) and attached by their base to a bottom 5 delimited by the fold lines 2.
La déformation du flan initial peut être obtenue à froid par un procédé classique d'emboutissage ou de pliage ; La figure 2 illustrant un formage à l'aide d'une presse d'emboutissage dont on a seulement représenté Le poinçon P et La matrice M.The deformation of the initial blank can be obtained when cold by a conventional drawing or bending process; Figure 2 illustrating a forming using a stamping press of which only the punch P and the matrix M have been shown.
La bride obtenue suivant ce procédé est ensuite complétée par Le percement des trous 6 destinés au passage de L'axe ou broche de verrouillage et par sa fixation rigide, par soudure ou autrement, à une pièce d'armature métallique 7.The flange obtained according to this process is then completed by the drilling of the holes 6 intended for the passage of the locking pin or pin and by its rigid fixing, by welding or otherwise, to a piece of metal reinforcement 7.
On souligne que toutes les opérations de découpage et de pliage du flan 1 et Le perçage des trous 6, peuvent être effectuées simultanément, à l'aide d'une presse équipée à cet effet.It is emphasized that all of the blanking and cutting operations for the blank 1 and the drilling of the holes 6 can be carried out simultaneously, using a press equipped for this purpose.
L'enlèvement des angles coupés par la diagonale 3 parallèle aux lignes de pliage 2 permet de ménager un bord droit 8 joignant les extrémités des plis 2, ces bords droits constituant les extrémités du fond 5.The removal of the angles cut by the diagonal 3 parallel to the fold lines 2 makes it possible to provide a straight edge 8 joining the ends of the folds 2, these straight edges constituting the ends of the bottom 5.
Selon le procédé de l'invention, on pourrait partir d'un flan dont seuls deux angles opposés coupés par la diagonale 3 seraient abattus, de façon à constituer Les bords droits 8. Toutefois, il est avantageux de couper également les deux autres angles, de façon que le sommet des branches 4 présente également un bord droit 9.According to the method of the invention, one could start from a blank of which only two opposite angles cut by the diagonal 3 would be cut down, so as to constitute the straight edges 8. However, it is advantageous to also cut the other two angles, so that the top of the branches 4 also has a straight edge 9.
On conçoit que La bride obtenue par La mise en oeuvre du procédé qui vient d'être décrit comporte un fond 5 et deux branches parallèles 4 s'inscrivant dans des triangles isocèles dont la base 10 est sensiblement plus grande que les côtés 11. Les branches 4 sont rattachées au fond 5 par l'intermédiaire de leur base 10 et sont pourvues de trous alignés 6 destinés au passage de la tige d'un organe de blocage 12 tel que boulon, broche ou axe de fixation imperdable, etc., dont un exemple de réalisation est représenté en traits fins à la figure 7.It will be understood that the flange obtained by the implementation of the process which has just been described comprises a bottom 5 and two parallel branches 4 inscribed in isosceles triangles whose base 10 is substantially larger than the sides 11. The branches 4 are attached to the bottom 5 via their base 10 and are provided with aligned holes 6 intended for the passage of the rod of a locking member 12 such as a bolt, pin or captive fixing pin, etc., including one exemplary embodiment is shown in thin lines in FIG. 7.
Le fond 5 présente une surface rectangulaire très allongée par rapport à sa largeur ; la longueur de ce fond étant, par exemple, plus de quatre fois supérieure à sa largeur.The bottom 5 has a very elongated rectangular surface relative to its width; the length of this bottom being, for example, more than four times its width.
D'autre part, le fond 5 présente une longueur L beaucoup plus grande que La distance d séparant L'axe des trous 6 et La face interne dudit fond, cette Longueur étant par exemple approximativement trois fois supérieure à Ladite distance.On the other hand, the bottom 5 has a length L much greater than the distance d separating the axis of the holes 6 and the internal face of said bottom, this length being for example approximately three times greater than said distance.
On a illustré à la figure 4, Le montage d'un élément d'armature métallique 7 destiné à occuper une position horizontale et équipé d'une bride de fixation selon l'invention, sur une poutre verticale 13. En considérant que le jeu (que L'on a volontairement exagéré) entre le chant de la poutre et La face interne du fond de la bride est le même que celui de La figure 3, on comprend aisément :FIG. 4 shows the mounting of a metal reinforcing element 7 intended to occupy a horizontal position and fitted with a fixing flange according to the invention, on a vertical beam 13. Considering that the clearance ( that we deliberately exaggerated) between the song of the beam and The internal face of the bottom of the flange is the same as that of FIG. 3, we easily understand:
- que L'amplitude de L'angle de pivotement possible α* de La bride selon l'invention est nettement pLus petite que celle de l'axe de pivotement possible α.1 d'une bride classique, d'où une meilleure conservation de l'horizontalité de l'élément d'armature métallique 7 ;- that the amplitude of the possible pivot angle α * of the flange according to the invention is significantly smaller than that of the possible pivot axis α.1 of a conventional flange, hence better conservation of the horizontality of the metal frame member 7;
- qu'en raison de cette latitude de basculement plus Limitée, l'effet de matriçage exercé par le bord inférieur 8 du fond 5 de la bride sur le chant de la. poutre 13 est pratiquement nul.- Because of this more limited tilting latitude, the forging effect exerted by the lower edge 8 of the bottom 5 of the flange on the edge of the. beam 13 is practically zero.
On observe qu'en prévoyant les lignes de pliage 2 à l'extérieur des extrémités des bords droits 8, il est possible d'obtenir un fond 5 comportant des extrémités débordantes par rapport à la base des branches 4. Ces extrémités débordantes peuvent être légèrement recour¬ bées vers l'extérieur, ce qui supprime tout appui cou¬ pant desdites extrémités contre le chant des poutres en boi s. It is observed that by providing the fold lines 2 outside the ends of the straight edges 8, it is possible to obtain a bottom 5 having projecting ends relative to the base of the branches 4. These projecting ends may be slightly curved outwards, which eliminates any support cou¬ pant of said ends against the edge of wooden beams.
