Description

Pièce de liaison et ensemble de pièces de liaison orientables Connecting piece and set of steerable connecting pieces
La présente invention concerne une pièce de liaison telle par exemple une plaque de tête ainsi qu'un ensemble de pièces de liaison orientables. Des pièces de liaison peuvent être utilisées pour la fixation ou le supportage de tous types de structures. Une pièce de liaison, appelée aussi parfois plaque de tête, comporte de manière classique une base plane et une plaque orientée perpendiculairement à la base. Une première pièce de liaison est fixée sur un support tel par exemple un mur, un plafond, une poutre, etc.. par l'intermédiaire de sa base et une seconde pièce de liaison est fixée, également par sa base, sur une extrémité d'une structure à fixer ou supporter. Les plaques des deux pièces de liaison sont alors mises l'une contre l'autre et boulonnées ensemble. Bien entendu, des alésages sont prévus d'une part dans chaque base des pièces de liaison pour permettre leur fixation sur la structure ou le support correspondant et d'autre part dans les plaques pour leur assemblage.The present invention relates to a connecting piece such for example a head plate and a set of steerable connecting pieces. Connecting parts can be used for fixing or supporting all types of structures. A connecting piece, sometimes also called head plate, conventionally comprises a flat base and a plate oriented perpendicularly to the base. A first connecting piece is fixed on a support such for example a wall, a ceiling, a beam, etc. through its base and a second connecting piece is fixed, also by its base, on one end. a structure to fix or support. The plates of the two connecting pieces are then put against each other and bolted together. Of course, bores are provided on the one hand in each base of the connecting pieces to allow their attachment to the structure or the corresponding support and on the other hand in the plates for their assembly.
Les domaines d'application de telles pièces de liaison sont variables. Elles peuvent être utilisées dès qu'il s'agit de fixer une structure à un support, notamment lorsque le support et la structure présentent des surfaces inclinées l'une par rapport à l'autre (sans être d'équerre). Un exemple non limitatif d'utilisation est la fixation de structures métalliques destinées à supporter des chemins de câbles. De telles structures sont parfois fixées sur des plafonds ou des poutres et l'utilisation de pièces de liaison orientables permet par exemple de fixer des montants verticaux sur un plafond incliné.The fields of application of such connecting pieces are variable. They can be used when it comes to fixing a structure to a support, especially when the support and the structure have surfaces that are inclined with respect to each other (without being square). A nonlimiting example of use is the attachment of metal structures for supporting cable trays. Such structures are sometimes fixed on ceilings or beams and the use of steerable connecting pieces allows for example to fix vertical uprights on a sloped ceiling.
Il est intéressant qu'une même paire de pièces de liaison puisse servir à des montages avec des inclinaisons différentes entre la pièce supportée et le support. Les pièces de liaison connues pouvant s'adapter à plusieurs inclinaisons sont généralement de deux types. Selon un premier type, divers angles sont prédéterminés et les plaques des pièces de liaison présentent plusieurs alésages, chaque alésage correspondant à une position angulaire prédéterminée. Selon un second type, les plaques des pièces de liaison comportent un alésage circulaire destiné au passage d'une vis et un trou oblong sensiblement en forme d'arc de cercle, le centre de l'arc de cercle correspondant à l'alésage pour une vis.It is interesting that the same pair of connecting pieces can be used for mounting with different inclinations between the supported part and the support. Known connecting pieces that can adapt to several inclinations are generally of two types. According to a first type, various angles are predetermined and the plates of the connecting pieces have several bores, each bore corresponding to a predetermined angular position. According to a second type, the plates of the connecting pieces comprise a circular bore for the passage of a screw and an oblong hole substantially in the shape of a circular arc, the center of the arc corresponding to the bore for a screw.
Les pièces de liaison du premier type permettent un excellent blocage d'une plaque par rapport à l'autre mais présentent comme inconvénient de ne pas pouvoir s'adapter à toutes les inclinaisons possibles entre le support et la structure supportée. Les pièces de liaison du second type peuvent quant à elles s'adapter à toutes les inclinaisons possibles entre le support et la structure supportée mais ne permettent pas un bon blocage des deux pièces de liaison l'une par rapport à l'autre. En effet, lorsqu'un effort est exercé sur la structure fixée ou supportée, les plaques ont tendance à pivoter l'une par rapport à l'autre, ce mouvement étant guidé par les boulons d'assemblage coulissant dans les trous oblongs.The connecting pieces of the first type allow an excellent blocking of one plate relative to the other but have the disadvantage of not ability to adapt to all possible inclinations between the support and the supported structure. The connecting pieces of the second type can in turn adapt to all possible inclinations between the support and the supported structure but do not allow a good locking of the two connecting pieces relative to each other. Indeed, when a force is exerted on the fixed or supported structure, the plates tend to pivot relative to each other, this movement being guided by the assembly bolts sliding in the oblong holes.
La présente invention a alors pour but de fournir une pièce de liaison qui permet d'une part de s'adapter à une large plage d'inclinaisons possibles entre le support et la structure supportée et d'autre part garantit un excellent maintien de la position relative des deux pièces de liaison lorsqu'une charge est exercée sur la structure supportée. De préférence, la structure du dispositif est simple et ne présente pas de surcoût par rapport à des pièces de liaison de l'art antérieur.The object of the present invention is therefore to provide a connecting piece which makes it possible on the one hand to adapt to a wide range of possible inclinations between the support and the supported structure and, on the other hand, guarantees excellent position retention. relative of the two connecting pieces when a load is exerted on the supported structure. Preferably, the structure of the device is simple and has no additional cost compared to connecting pieces of the prior art.
A cet effet, la présente invention propose une pièce de liaison du type comportant d'une part des moyens de fixation sur un support et d'autre part une plaque, perforée, destinée à la fixation d'une structure ou d'une autre pièce de liaison.For this purpose, the present invention proposes a connecting piece of the type comprising on the one hand fixing means on a support and on the other hand a plate, perforated, intended for fixing a structure or another piece link.
Selon la présente invention, la plaque comporte une première perforation ainsi qu'au moins une seconde perforation se présentant sous la forme d'un trou oblong, éventuellement incurvé, le trou oblong étant orienté de telle sorte que son axe longitudinal présente, en un point donné, une inclinaison sensible par rapport à la tangente en ce point d'un cercle ayant pour centre le point considéré de la première perforation et passant par le point considéré de la seconde perforation. Grâce à cette géométrie, lorsque les pièces de liaison sont reliées par des boulons traversant des perforations mises en correspondance de leurs plaques respectives et qu'une charge est exercée, les boulons sont plaqués contre les bords de la seconde perforation empêchant ainsi un glissement relatif entre les deux plaques. Avec cette géométrie, le trou oblong de la seconde perforation, sous la charge, ne sert pas de guide au boulon correspondant et bloque tout mouvement.According to the present invention, the plate comprises a first perforation and at least one second perforation in the form of an oblong hole, possibly curved, the oblong hole being oriented so that its longitudinal axis has a point given, a sensible inclination with respect to the tangent at this point of a circle having as center the considered point of the first perforation and passing through the considered point of the second perforation. Thanks to this geometry, when the connecting pieces are connected by bolts passing through perforations matched with their respective plates and a load is exerted, the bolts are pressed against the edges of the second perforation thus preventing a relative sliding between the two plates. With this geometry, the oblong hole of the second perforation, under load, does not serve as a guide to the corresponding bolt and blocks any movement.
L'angle fait entre la tangente du cercle passant par un point de la seconde perforation et ayant pour centre un point de la première perforation et l'axe longitudinal du trou oblong (ou sa tangente au point considéré) est de préférence supérieur à 10°.The angle made between the tangent of the circle passing through a point of the second perforation and having at its center a point of the first perforation and the longitudinal axis of the oblong hole (or its tangent at the point in question) is preferably greater than 10 °.
Dans une pièce de liaison selon l'invention, la première perforation peut être un alésage circulaire destiné à recevoir un boulon. La seconde perforation peut quant à elle être un trou oblong rectiligne. Lorsque les charges supportées sont importantes, on peut prévoir que la première perforation est un alésage circulaire destiné à recevoir un boulon, et que la plaque comporte deux trous oblongs rectilignes inclinés, c'est-à-dire dont l'axe longitudinal ne traverse pas la première perforation. La liaison entre deux pièces de liaison peut être ainsi réalisée à l'aide de trois boulons. Dans cette variante de réalisation, un trou oblong est par exemple plus court que l'autre et est le plus proche de la première perforation. Les deux trous oblongs sont par exemple inclinés l'un par rapport à l'autre.In a connecting piece according to the invention, the first perforation may be a circular bore for receiving a bolt. The second perforation can be a rectilinear oblong hole. When the supported loads are large, it is possible to provide that the first perforation is a circular bore intended to receive a bolt, and that the plate comprises two oblong rectilinear holes inclined, that is to say whose longitudinal axis does not cross. the first perforation. The connection between two connecting pieces can be made using three bolts. In this embodiment, an oblong hole is for example shorter than the other and is closest to the first perforation. The two oblong holes are for example inclined relative to each other.
Dans une forme de réalisation d'une pièce de liaison selon l'invention, les moyens de fixation sur un support comportent par exemple une base s'étendant dans un plan sensiblement perpendiculaire à la plaque. Dans cette forme de réalisation, la base et la plaque sont avantageusement constituées d'une tôle pliée à angle droit. De cette manière, la pièce de liaison peut être réalisée par découpage et pliage.In one embodiment of a connecting piece according to the invention, the fixing means on a support comprise for example a base extending in a plane substantially perpendicular to the plate. In this embodiment, the base and the plate advantageously consist of a folded sheet at right angles. In this way, the connecting piece can be made by cutting and folding.
Dans cette forme de réalisation pliée, une première variante de réalisation prévoit que sur les deux bords voisins du bord plié séparant la base de la plaque, la plaque et la base présentent respectivement chacune un rebord sensiblement à angle droit orienté vers la base et la plaque respectivement, et que les rebords de la plaque présentent chacun du côté de leur extrémité proche de la base une patte repliée de manière à s'introduire dans une fente correspondante réalisée dans un rebord de la base.In this folded embodiment, a first variant embodiment provides that on the two adjacent edges of the folded edge separating the base of the plate, the plate and the base each respectively have a substantially perpendicular edge directed towards the base and the plate. respectively, and that the edges of the plate each have on the side of their end near the base a tab folded so as to be introduced into a corresponding slot made in a rim of the base.
Une seconde variante de réalisation prévoit quant à elle que sur les deux bords voisins du bord plié séparant la base de la plaque, la plaque et la base présentent respectivement chacune un rebord sensiblement à angle droit orienté vers la base et la plaque respectivement, et que les rebords de la base présentent chacun du côté de leur extrémité proche de la plaque une patte repliée de manière à s'introduire dans une fente correspondante réalisée dans un rebord de la plaque.A second variant of embodiment provides that on the two adjacent edges of the folded edge separating the base of the plate, the plate and the base each respectively have a flange substantially at right angles to the base and the plate respectively, and that the edges of the base each have on the side of their end close to the plate a tab folded so as to be introduced into a corresponding slot made in a flange of the plate.
Enfin une troisième variante de réalisation pliée prévoit que sur chacun des deux bords voisins du bord plié séparant la base de la plaque, la plaque présente un rebord sensiblement à angle droit orienté vers la base, que ces deux rebords de la plaque se prolongent au-delà de la plaque en direction de la base et sont repliés à angle droit de manière à venir reposer contre la base, et que les parties repliées des rebords présentent chacune au moins une perforation correspondant à une perforation de la base destinée à sa fixation. De telles pièces de liaison réalisées par découpage et pliage d'une tôle sont avantageusement en acier prégalvanisé.Finally, a third folded embodiment variant provides that on each of the two adjacent edges of the folded edge separating the base of the plate, the plate has a rim substantially at right angles to the base, that these two edges of the plate extend beyond the plate towards the base and are bent at a right angle so as to rest against the base, and that the folded portions of the flanges each have at least one perforation corresponding to a perforation of the base for fixing it. Such connecting pieces made by cutting and folding a sheet are advantageously made of pregalvanized steel.
La présente invention concerne également un ensemble de deux pièces de liaison comportant chacune une plaque perforée, les deux plaques perforées étant disposées l'une contre l'autre, caractérisé en ce que les deux pièces de liaison sont des pièces de liaison telles que décrites ci-dessus. Dans cet ensemble de deux pièces de liaison, les deux pièces de liaison peuvent être identiques.The present invention also relates to a set of two connecting pieces each comprising a perforated plate, the two perforated plates being arranged one against the other, characterized in that the two connecting pieces are connecting pieces as described herein. -above. In this set of two connecting pieces, the two connecting pieces can be identical.
Enfin, la présente invention concerne aussi un étrier de liaison comportant une base destinée à être fixée sur un support et deux branches perforées parallèles l'une à l'autre et reliées par la base. Dans un tel étrier selon l'invention, chaque branche perforée se présente sous la forme d'une plaque qui comporte une première perforation ainsi qu'au moins une seconde perforation se présentant sous la forme d'un trou oblong, éventuellement incurvé, le trou oblong étant orienté de telle sorte que son axe longitudinal présente, en un point donné, une inclinaison sensible par rapport à la tangente en ce point d'un cercle ayant pour centre un point de la première perforation et passant par le point considéré de la seconde perforation.Finally, the present invention also relates to a connecting stirrup comprising a base intended to be fixed on a support and two perforated branches parallel to one another and connected by the base. In such a stirrup according to the invention, each perforated branch is in the form of a plate which has a first perforation and at least one second perforation in the form of an oblong hole, optionally curved, the hole oblong being oriented so that its longitudinal axis has, at a given point, a substantial inclination with respect to the tangent at this point of a circle having at its center a point of the first perforation and passing through the considered point of the second perforation.
Des détails et avantages de la présente invention ressortiront mieux de la description qui suit, faite en référence aux dessins schématiques annexés sur lesquels :Details and advantages of the present invention will emerge more clearly from the description which follows, made with reference to the appended diagrammatic drawings in which:
La figure 1 représente une première forme de réalisation d'un ensemble de pièces de liaison selon l'invention,FIG. 1 represents a first embodiment of a set of connecting pieces according to the invention,
La figure 2 représente de façon plus schématique l'ensemble de la figure 1 utilisée pour la suspension d'une structure, La figure 3 est une vue correspondant à la figure 2 dans un autre exemple d'application,FIG. 2 is a more schematic representation of the assembly of FIG. 1 used for the suspension of a structure; FIG. 3 is a view corresponding to FIG. 2 in another example of application;

La figure 5 montre un ensemble de deux pièces de liaison selon la figure 4 assemblées,Figure 5 shows a set of two connecting pieces according to the figure 4 assemblies,
La figure 6 montre une troisième forme de réalisation d'une pièce de liaison selon l'invention, etFIG. 6 shows a third embodiment of a connecting piece according to the invention, and
La figure 7 montre un ensemble de deux pièces de liaison selon la figure 6 assemblées.Figure 7 shows a set of two connecting pieces according to Figure 6 assembled.
De manière classique, une pièce de liaison selon la présente invention comporte d'une part une base 2 et d'autre part une plaque 4. La base 2 et la plaque 4 sont perpendiculaires l'une par rapport à l'autre.Conventionally, a connecting piece according to the present invention comprises on the one hand a base 2 and on the other hand a plate 4. The base 2 and the plate 4 are perpendicular to each other.
La base 2 présente la forme d'une bande de relativement faible largeur et comporte des trous oblongs 6 permettant la fixation de la pièce de liaison sur un support. Dans l'exemple de réalisation représenté sur les figures 1 à 3, la base 2 comporte deux trous oblongs distants l'un de l'autre mais dont les axes longitudinaux sont confondus. Toute autre configuration de trous pour réaliser la fixation de la base 2 sur un support peut être envisagée ici. On peut par exemple n'avoir que des alésages circulaires, ou avoir à la fois un ou plusieurs alésages circulaires et un ou plusieurs alésages oblongs et les trous oblongs peuvent être orientés différemment par rapport aux trous oblongs de la figure 1.The base 2 has the shape of a band of relatively small width and has oblong holes 6 for fixing the connecting piece on a support. In the embodiment shown in Figures 1 to 3, the base 2 comprises two oblong holes spaced apart from each other but whose longitudinal axes are coincident. Any other configuration of holes for fixing the base 2 to a support can be envisaged here. For example, it is possible to have only circular bores, or to have both one or more circular bores and one or more oblong bores and the oblong holes can be oriented differently with respect to the oblong holes of FIG.
La plaque 4 peut être de forme quelconque. Elle présente un côté correspondant à un bord longitudinal de la base 2. Dans l'exemple de réalisation de la figure 1 , la plaque 4 présente la forme d'un carré surmonté d'une pointe sensiblement triangulaire, la pointe triangulaire étant opposée à la base 2.The plate 4 may be of any shape. It has a side corresponding to a longitudinal edge of the base 2. In the embodiment of Figure 1, the plate 4 has the shape of a square surmounted by a substantially triangular tip, the triangular tip being opposite the base 2.
La plaque 4 présente des perforations. Dans la forme de réalisation des figures 1 à 3 la plaque 4 comporte tout d'abord un alésage circulaire 8. Sur la figure 1 , un premier boulon 10 traverse l'alésage circulaire pour réaliser la liaison avec une seconde pièce de liaison (et cache l'alésage circulaire). Dans cette première forme de réalisation, l'alésage circulaire 8 de la plaque 4 se trouve au niveau de la partie triangulaire de cette plaque, c'est-à-dire à l'opposé de la base 2.The plate 4 has perforations. In the embodiment of FIGS. 1 to 3, the plate 4 firstly comprises a circular bore 8. In FIG. 1, a first bolt 10 passes through the circular bore to make the connection with a second connecting piece (and concealed the circular bore). In this first embodiment, the circular bore 8 of the plate 4 is at the triangular portion of this plate, that is to say opposite to the base 2.
La plaque 4 présente également un premier trou oblong 12 rectiligne et comportant un grand axe 14. Ce premier trou oblong 12 est disposé de telle sorte que d'une part l'axe longitudinal 14 de ce premier trou oblong 12 ne passe pas par l'alésage circulaire réalisé dans la plaque 4 et d'autre part la projection orthogonale O" du centre O de l'alésage circulaire 8 réalisé dans la plaque 4 sur l'axe longitudinal 14 ne se trouve pas dans le premier trou oblong 12. Pour chaque point du trou oblong 12, on remarque que le grand axe 14 est sensiblement incliné par rapport à la tangente en ce point d'un cercle passant par ledit point et ayant pour centre l'alésage circulaire 8.The plate 4 also has a first elongated rectilinear hole 12 having a major axis 14. This first elongated hole 12 is arranged so that on the one hand the longitudinal axis 14 of this first oblong hole 12 does not pass through the circular bore made in the plate 4 and secondly the orthogonal projection O "of the center O of the circular bore 8 formed in the plate 4 on the longitudinal axis 14 is not in the first oblong hole 12. For each point of the oblong hole 12, it is noted that the major axis 14 is substantially inclined with respect to the tangent at this point of a circle passing through said point and having as a center the circular bore 8.
Cette géométrie particulière des perforations réalisées dans la plaque 4 permet de supprimer, ou tout du moins de réduire très fortement, tout risque de glissement entre deux pièces de liaison montées dos à dos comme représenté sur la figure 1 et assemblées à l'aide du premier boulon 10 passant par l'alésage circulaire 8 d'une première plaque et le premier trou oblong 12 de la seconde plaque et un second boulon 16 traversant le premier trou oblong 12 de la première plaque et l'alésage circulaire 8 de la seconde plaque.This particular geometry of the perforations made in the plate 4 makes it possible to eliminate, or at least to reduce very strongly, any risk of sliding between two connecting pieces mounted back to back as shown in FIG. 1 and assembled using the first bolt 10 passing through the circular bore 8 of a first plate and the first oblong hole 12 of the second plate and a second bolt 16 passing through the first oblong hole 12 of the first plate and the circular bore 8 of the second plate.
Les figures 2 et 3 illustrent schématiquement l'ensemble de deux pièces de liaison représenté sur la figure 1 et expliquent son fonctionnement.Figures 2 and 3 schematically illustrate the set of two connecting parts shown in Figure 1 and explain its operation.
Sur les figures 2 et 3, pour des raisons de clarté, les premiers trous oblongs 12 des deux pièces de liaison ont été représentés en traits pleins de même que les alésages circulaires 8. Sur ces deux figures 2 et 3, une première pièce de liaison 18 est fixée par sa base à un support non horizontal, tel un plafond 20, tandis qu'une seconde pièce de liaison 22 porte une structure 24 fixée sur sa base.In FIGS. 2 and 3, for the sake of clarity, the first oblong holes 12 of the two connecting pieces have been represented in solid lines as well as the circular bores 8. In these two figures 2 and 3, a first connecting piece 18 is fixed by its base to a non-horizontal support, such as a ceiling 20, while a second connecting piece 22 carries a structure 24 fixed on its base.
Ici, les deux pièces de liaison sont mises dos à dos comme représenté sur la figure 1. Les plaques de ces pièces de liaison viennent ainsi au contact l'une de l'autre par leurs faces opposées à leurs bases. On remarque sur les figures 2 et 3 que l'inclinaison entre la structure 24 et le plafond 20 varie. En faisant varier la position des boulons dans les premiers trous oblongs 12 des pièces de liaison on obtient un réglage continu de la position relative des deux pièces de liaison. Lorsque la structure 24 est soumise à une charge 26, symbolisée par une flèche verticale, un couple est exercé entre les deux pièces de liaison 18 et 22 tendant à faire pivoter ces deux plaques l'une par rapport à l'autre. Les deux pièces de liaison étant maintenues par les boulons 10 et 16, des forces s'exercent au niveau de ces boulons et sont représentées par des flèches sur les figures 2 et 3. On remarque que ces forces tendent à plaquer les boulons contre les parois des premiers trous oblongs 12 dans lesquels passent les boulons. De ce fait, aucun coulissement des boulons dans les premiers trous oblongs 12 n'est possible. On réalise ainsi un blocage des deux pièces de liaison l'une par rapport à l'autre. On remarque que plus la charge 26 est importante, plus le blocage est lui aussi important.Here, the two connecting pieces are set back to back as shown in Figure 1. The plates of these connecting parts thus come into contact with each other by their opposite faces to their bases. It is noted in Figures 2 and 3 that the inclination between the structure 24 and the ceiling 20 varies. By varying the position of the bolts in the first oblong holes 12 of the connecting pieces is obtained a continuous adjustment of the relative position of the two connecting pieces. When the structure 24 is subjected to a load 26, symbolized by a vertical arrow, a torque is exerted between the two connecting pieces 18 and 22 tending to pivot these two plates relative to each other. The two connecting pieces being held by the bolts 10 and 16, forces are exerted at these bolts and are represented by arrows in Figures 2 and 3. Note that these forces tend to press the bolts against the walls first oblong holes 12 in which the bolts pass. As a result, no sliding of the bolts in the first oblong holes 12 is possible. This causes a blocking of the two connecting pieces relative to each other. Note that the higher the load 26, the more the blockage is him also important.
Les figures 4 et 5 représentent une variante de réalisation des pièces de liaison des figures 1 à 3. Les modifications apportées ici concernent uniquement les perforations réalisées dans la plaque 4. On remarque que cette plaque comporte un alésage circulaire 8, un premier trou oblong 12 et également un second trou oblong 28. L'alésage circulaire 8 est disposé du côté de la base 2 tandis que les trous oblongs12, 28 se trouvent du côté de la partie triangulaire de la plaque 4.FIGS. 4 and 5 show an alternative embodiment of the connecting pieces of FIGS. 1 to 3. The modifications made here concern only the perforations made in the plate 4. It should be noted that this plate comprises a circular bore 8, a first oblong hole 12 and also a second oblong hole 28. The circular bore 8 is disposed on the side of the base 2 while the oblong holes 12, 28 are on the side of the triangular portion of the plate 4.
Le second trou oblong 28 est sensiblement parallèle au premier trou oblong 12. Pour chacun de ces trous oblongs 12, 28, les remarques faites précédemment en rapport avec la figure 1 sont également valables. Ainsi, pour chacun de ces trous oblongs, l'axe longitudinal du trou oblong ne passe pas par l'alésage circulaire 8. En outre la projection orthogonale du centre de l'alésage circulaire 8 sur les axes longitudinaux des trous oblongs ne se trouve pas à l'intérieur des trous oblongs. L'assemblage de deux pièces de liaison de la figure 4 est montré sur la figure 5. On remarque ici que trois boulons sont utilisés. Un tel ensemble peut donc être utilisé pour des charges plus lourdes que l'ensemble de la figure 1.The second oblong hole 28 is substantially parallel to the first oblong hole 12. For each of these oblong holes 12, 28, the remarks previously made with reference to FIG. 1 are also valid. Thus, for each of these oblong holes, the longitudinal axis of the oblong hole does not pass through the circular bore 8. In addition, the orthogonal projection of the center of the circular bore 8 on the longitudinal axes of the oblong holes is not found inside the oblong holes. The assembly of two connecting pieces of Figure 4 is shown in Figure 5. It is noted here that three bolts are used. Such an assembly can therefore be used for heavier loads than the whole of FIG.
On réalise ici exactement de la même façon qu'expliquée plus haut, un blocage des deux pièces de liaison l'une par rapport à l'autre lorsqu'une charge est exercée sur l'une des pièces de liaison. Cet autoblocage est obtenu grâce aux caractéristiques géométriques des trous oblongs 12, 28 et de leur position relative par rapport à l'alésage circulaire 8. En considérant l'alésage circulaire 8 et l'un des trous oblongs, on remarque que pour chaque point du trou oblong considéré la tangente du cercle passant par ce point ayant pour centre le centre de l'alésage circulaire 8 est inclinée par rapport à l'axe longitudinal du trou oblong correspondant. On pourrait retrouver une telle caractéristique avec des trous oblongs non pas rectilignes mais incurvés.Here, in exactly the same way as explained above, the two connecting pieces are locked relative to one another when a load is exerted on one of the connecting pieces. This self-locking is obtained thanks to the geometric characteristics of the oblong holes 12, 28 and their relative position with respect to the circular bore 8. Considering the circular bore 8 and one of the oblong holes, it is noted that for each point of the oblong hole considered the tangent of the circle passing through this point having for center the center of the circular bore 8 is inclined relative to the longitudinal axis of the corresponding oblong hole. Such a characteristic could be found with oblong holes that are not rectilinear but curved.
La manière de réaliser les pièces de liaison des figures 1 à 5 est originale. On remarque rapidement sur ce dessin que les pièces de liaison présentées peuvent être réalisées par pliage d'une tôle. Habituellement, les pièces de liaison sont plutôt réalisées par soudage. En effet, les charges auxquelles sont soumises ces pièces de liaison sont importantes et une construction soudée est alors préférée. Dans les deux variantes de réalisation des figures 1 à 5, les pièces de liaison représentées présentent une arête 30 séparant la base 2 de la plaque 4. Cette arête 30 correspond au bord plié commun entre la base 2 et la plaque 4. Les bords de la base 2 voisins de l'arête 30 portent chacun un rebord 32 replié à angle droit par rapport à la base 2 du même côté que la plaque 4. De même, les bords de la plaque 4 voisins de l'arête 30 présentent chacun un rebord 34 replié à angle droit par rapport à la plaque 4 du côté de la plaque portant la base 2. Dans les formes de réalisation représentées sur les figures 1 à 5, les rebords 34 se trouvent à l'intérieur des rebords 32. Les rebords 32 et 34 sont reliés entre eux de manière à éviter une ouverture de l'angle formé entre la base 2 et la plaque 4 au niveau de l'arête 30. A cet effet, chaque rebord 34 présente à son extrémité se trouvant du côté de la base 2 une patte 36 repliée à angle droit vers l'extérieur. Les rebords 32 comportent quant à eux chacun une fente 38 dans laquelle vient se loger à chaque fois une patte 36.The manner of making the connecting pieces of Figures 1 to 5 is original. It is quickly noted in this drawing that the connecting pieces presented can be made by folding a sheet. Usually, the connecting pieces are rather made by welding. Indeed, the loads to which these connecting pieces are subjected are important and a welded construction is then preferred. In both alternative embodiments of FIGS. 1 to 5, the connection pieces shown have an edge 30 separating the base 2 from the plate 4. This edge 30 corresponds to the folded edge common between the base 2 and the plate 4. The edges of the base 2 adjacent to the edge 30 each carry a flange 32 folded at right angles to the base 2 on the same side as the plate 4. Similarly, the edges of the plate 4 adjacent to the edge 30 each have a flange 34 folded at right angles to the plate 4 on the side of the plate carrying the base 2. In the embodiments shown in Figures 1 to 5, the flanges 34 are inside the flanges 32. The flanges 32 and 34 are interconnected so as to avoid an opening of the angle formed between the base 2 and the plate 4 at the edge 30. For this purpose, each flange 34 has at its end on the side of the base 2 a tab 36 bent at right angles to the 'outside. The flanges 32 each comprise a slot 38 in which each lug 36 is received.
En variante de réalisation non représentée sur les dessins annexés, on pourrait prévoir qu'une patte est portée par chacun des rebords de la base 2 tandis que les fentes se trouvent sur les rebords de la plaque 4.As an alternative embodiment not shown in the accompanying drawings, it could be provided that a tab is carried by each of the edges of the base 2 while the slots are on the edges of the plate 4.
Grâce à cette structure originale, la tête de plaque peut être réalisée par pliage à partir d'une tôle prégalvanisée (et sans soudure).Thanks to this original structure, the plate head can be made by folding from a pregalvanized sheet (and seamless).
Les figures 6 et 7 montrent une troisième variante de réalisation d'une pièce de liaison selon l'invention.Figures 6 and 7 show a third embodiment of a connecting piece according to the invention.
Dans cette forme de réalisation préférée, on remarque, par rapport aux deux formes précédentes, que les perforations de la plaque comportent, comme pour la seconde forme de réalisation, un alésage circulaire, un premier trou oblong 12 et un second trou oblong 28. On remarque également que la pièce de liaison représentée sur les deux dernières figures est obtenue à partir d'une tôle (prégalvanisée) pliée mais le pliage est réalisé différemment que pour les deux premières formes de réalisation de l'invention. En ce qui concerne les perforations réalisées dans la plaque 4, on remarque que dans la seconde forme de réalisation l'alésage circulaire 8 se trouvait entre les axes longitudinaux des trous oblongs 12 et 28. Dans cette troisième forme de réalisation, l'alésage circulaire 8 se trouve d'un même côté des deux axes longitudinaux des trous oblongs. Comme pour les deux autres formes de réalisation, aucun des axes longitudinaux des trous oblongs ne traverse l'alésage circulaire 8 et la projection orthogonale du centre de l'alésage circulaire 8 sur l'axe longitudinal d'un trou oblong est située à l'extérieur de ce trou oblong. On a également un angle entre l'axe longitudinal d'un trou oblong et la tangente d'un cercle passant par un point de ce trou oblong et ayant pour centre le centre de l'alésage circulaire 8, et ce quelque soit le point du trou oblong considéré.In this preferred embodiment, it will be noted, with respect to the two preceding forms, that the perforations of the plate comprise, as in the second embodiment, a circular bore, a first oblong hole 12 and a second oblong hole 28. also note that the connecting piece shown in the last two figures is obtained from a sheet (pregalvanized) folded but the folding is performed differently than for the first two embodiments of the invention. With regard to the perforations made in the plate 4, it is noted that in the second embodiment the circular bore 8 was between the longitudinal axes of the oblong holes 12 and 28. In this third embodiment, the circular bore 8 is on the same side of the two longitudinal axes of the oblong holes. As for the other two forms in fact, none of the longitudinal axes of the oblong holes passes through the circular bore 8 and the orthogonal projection of the center of the circular bore 8 on the longitudinal axis of an oblong hole is located outside this oblong hole. There is also an angle between the longitudinal axis of an oblong hole and the tangent of a circle passing through a point of this oblong hole and centered on the center of the circular bore 8, and whatever the point of the oblong hole considered.
La structure de la pièce de liaison de la troisième forme de réalisation comporte elle aussi une base 2 et une plaque 4 séparées par une arête 30. La plaque 4 comporte ici un rebord 40 sur chacun de ses bords voisins de l'arête 30. Ce rebord 40 est prolongé du côté de la base 2 au-delà de la plaque 4 et est replié à angle droit de manière à reposer contre la base 2. Les parties repliées des rebords 40 forment des languettes 42. Dans la forme de réalisation représentée, les languettes 42 se trouvent du côté de la base 2 orientées vers la plaque 4. Toutefois, ces languettes 42 pourraient se trouver de l'autre côté de la base 2. Comme on peut le remarquer, chacune de ces languettes recouvrent sensiblement la moitié de la base 2. Elles peuvent également être plus courtes et ne recouvrir chacune par exemple qu'un tiers ou un quart de la base 2. Ces languettes 42 sont alors perforées selon un schéma similaire à celui de la base 2. Dans l'exemple représenté au dessin la base 2 comporte quatre perforations, deux trous oblongs et deux alésages circulaires. Ainsi, dans chacune des languettes 42, sont réalisés un trou oblong et un alésage circulaire, ou dans le cas de languettes plus courtes par exemple uniquement un trou oblong pour la forme de réalisation représentée. Lorsque la pièce de liaison est alors fixée sur un support (plafond, structure, ou autre), les boulons utilisés pour la fixation traversent à la fois les languettes 42 et la base 2. Le serrage de ces boulons permet de maintenir l'une contre l'autre la base et les languettes et donc de rigidifier l'arête 30. On utilise également, toujours pour rigidifier l'arête 30, des nervures 44 de rigidification disposées transversalement au niveau de l'arête 30. Ces nervures 44 sont obtenues par réalisation d'un bossage, comme on peut le voir sur la figure 7. Sur cette figure 7, on a représenté dos à dos deux pièces de liaison telles celle de Ia figure 6. Les boulons de liaison entre ces deux pièces de liaison n'ont pas été représentés. On remarque alors que les trous oblongs d'une plaque se croisent avec les trous oblongs de la plaque opposée sensiblement à angle droit. Toutes les pièces de liaison présentées ci-dessus permettent, lorsqu'elles sont utilisées deux à deux de réduire le glissement entre ces deux pièces de liaison. La solidité de la structure réalisée à l'aide de ces pièces de liaison est donc accrue. La géométrie des perforations réalisées dans les pièces de liaison selon l'invention permet de réaliser un autoblocage des deux pièces de liaison montées dos à dos. Comme vu plus haut en référence aux figures 2 et 3, plus la charge exercée sur les pièces de liaison est importante, meilleur est le blocage entre les deux pièces de liaison montées dos à dos. Les pièces présentées permettent d'avoir un réglage continu de la position angulaire entre deux têtes de plaque montées dos à dos. Il est possible avec des pièces de liaison selon l'invention de réaliser une variation continue de l'orientation des plaques sur 45°.The structure of the connecting piece of the third embodiment also has a base 2 and a plate 4 separated by an edge 30. The plate 4 here comprises a flange 40 on each of its edges adjacent to the edge 30. This flange 40 is extended on the side of the base 2 beyond the plate 4 and is folded at a right angle so as to rest against the base 2. The folded portions of the flanges 40 form tabs 42. In the embodiment shown, the tabs 42 are on the side of the base 2 facing the plate 4. However, these tabs 42 could be on the other side of the base 2. As can be seen, each of these tabs substantially cover half of base 2. They can also be shorter and each cover for example only one third or one quarter of the base 2. These tabs 42 are then perforated in a similar pattern to that of the base 2. In the example shown at drawing the base 2 has four perforations, two oblong holes and two circular bores. Thus, in each of the tabs 42, there is provided an oblong hole and a circular bore, or in the case of shorter tongues for example only an oblong hole for the embodiment shown. When the connecting piece is then fixed on a support (ceiling, structure, or other), the bolts used for fixing pass through both the tabs 42 and the base 2. The tightening of these bolts allows to maintain one against the other the base and the tongues and thus to stiffen the edge 30. It is also used, always to stiffen the edge 30, stiffening ribs 44 arranged transversely at the edge 30. These ribs 44 are obtained by Embodiment of a boss, as can be seen in FIG. 7. In this FIG. 7, there is shown back-to-back two connecting pieces such as that of FIG. 6. The connecting bolts between these two connecting pieces have not been represented. Note that the oblong holes of a plate intersect with the oblong holes of the opposite plate substantially at right angles. All the connecting pieces presented above allow, when used in pairs to reduce slippage between these two connecting pieces. The strength of the structure made using these connecting pieces is increased. The geometry of the perforations made in the connecting pieces according to the invention allows self-locking of the two connecting pieces mounted back to back. As seen above with reference to Figures 2 and 3, the greater the load on the connecting pieces is important, the better is the blockage between the two connecting pieces mounted back to back. The parts presented allow a continuous adjustment of the angular position between two plate heads mounted back to back. It is possible with connecting pieces according to the invention to achieve a continuous variation of the orientation of the plates over 45 °.
Pour réaliser un montage de deux pièces de liaison dos à dos, on utilise de préférence deux pièces de liaison similaires. Il n'est pas nécessaire de prévoir une plaque droite et une plaque gauche. On peut ainsi utiliser la même plaque pour le montage sur un support que pour le montage sur un plafond.To mount two back-to-back connecting pieces, two similar connecting pieces are preferably used. It is not necessary to provide a straight plate and a left plate. The same plate can thus be used for mounting on a support as for mounting on a ceiling.
Les formes de réalisation proposées permettent l'utilisation de boulons avec des vis classiques. Il n'est pas nécessaire avec des pièces de liaison selon l'invention de protéger les pas de vis des vis utilisées.The proposed embodiments allow the use of bolts with conventional screws. It is not necessary with connecting pieces according to the invention to protect the threads of the screws used.
Les pièces de liaison décrites et représentées aux dessins présentent également l'avantage d'être réalisées à partir d'une tôle découpée et pliée. Aucune soudure n'est nécessaire. Toutefois, une construction soudée pourrait être envisagée. La construction découpée et pliée permet toutefois de faire des économies sensibles dans la réalisation des pièces de liaison. Ces économies peuvent être faite d'une part dans le procédé de réalisation de la pièce de liaison et d'autre part dans la quantité de matière utilisée puisque les pliages proposés permettent de réduire l'épaisseur de la tôle utilisée (figures 6 et 7).The connecting pieces described and shown in the drawings also have the advantage of being made from a cut sheet and bent. No soldering is necessary. However, a welded construction could be considered. The cut and folded construction, however, allows significant savings in the realization of the connecting pieces. These savings can be made on the one hand in the method of producing the connecting piece and on the other hand in the quantity of material used since the bends proposed make it possible to reduce the thickness of the sheet used (FIGS. 6 and 7). .
Une autre forme de réalisation d'une pièce de liaison selon l'invention, non représentée sur les dessins, présente la forme d'un étrier. Ce dernier comporte alors de manière classique une base et deux branches. Ici, les deux branches sont des plaques perforées, similaires aux plaques 4 décrites ci-dessus, disposées parallèlement et face à face en étant reliées par la base de l'étrier. Une telle pièce de liaison en forme d'étrier peut par exemple être utilisée pour la fixation d'une cornière (profilé en U ou C) sur un plafond incliné : la base de l'étrier est alors fixée sur Ie plafond et les ailes de la cornière, perforées, sont fixées sur les branches de l'étrier. Les perforations réalisées dans la cornière correspondent alors de préférence aux perforations réalisées dans les branches de l'étrier.Another embodiment of a connecting piece according to the invention, not shown in the drawings, has the shape of a stirrup. The latter then comprises conventionally a base and two branches. Here, the two branches are perforated plates, similar to the plates 4 described above, arranged parallel and face to face being connected by the base of the stirrup. Such a stirrup-shaped connecting piece can for example be used for fixing an angle bracket (U or C profile) on an inclined ceiling: the base of the stirrup is then fixed on the ceiling and the wings of the angle, perforated, are fixed on the branches of the stirrup. The perforations made in the angle then correspond preferably to perforations made in the branches of the stirrup.
La présente invention ne se limite pas aux formes de réalisation décrites ci-dessus à titre d'exemples non limitatifs. Elle concerne également les variantes de réalisation à la portée de l'homme du métier dans le cadre des revendications ci-après. The present invention is not limited to the embodiments described above by way of non-limiting examples. It also relates to the variants within the scope of those skilled in the art within the scope of the claims below.
