Abstract
Description
L'invention concerne un profilé dont la géométrie se prête à un grand nombre de modes et de configurations d'assemblage avec des profilés identiques pour constituer une structure assemblée notamment métalli que. The invention relates to a profile whose geometry lends itself to a large number of assembly modes and configurations with identical profiles to constitute an assembled structure, in particular a metal structure.
Elle vise ainsi un profilé dont la géométrie permet un assemblage, par soudage ou boulonnage ou analogue, dans au moins trois orientations possibles, donc préséntant au moins trois surfaces planes non coplanaires mais éventuellement parallèles, ainsi qu'un boulonnage direct ou un assemblage par l'intermédiaire de mors ou de mâchoires de serrage boulonnées. It thus relates to a profile whose geometry allows assembly, by welding or bolting or the like, in at least three possible orientations, therefore having at least three flat surfaces not coplanar but possibly parallel, as well as direct bolting or assembly by the with bolted jaws or clamping jaws.
L'-invention propose ainsi un profilé pour structure métallique boulonnée, caractérisé en ce qu'il comporte une section constante avec une portion conformée en T avec une aile raccordée à angle droit à une âme, et une portion. complémentaire comportant une tranche parallèle à l'aile et au moins un flanc latéral qui lui est raccordé à angle droit et qui s'étend à partir de celle-ci en direction de l'âme à laquelle il est raccordé. The invention thus provides a profile for a bolted metal structure, characterized in that it has a constant section with a T-shaped portion with a wing connected at right angles to a core, and a portion. complementary comprising a section parallel to the wing and at least one lateral flank which is connected to it at right angles and which extends therefrom in the direction of the core to which it is connected.
Selon des dispositions préférées de l'invention, éventuellement combinées - il admet un plan longitudinal de symétrie passant par l'âme du T, sa tranche étant bordée des deux côtés par des flancs parallèles qui lui sont perpendiculaires et qui se raccordent à cette âme du T par deux flancs inclinés - ce flanc latéral est coplanaire avec l'âme du T,- un flanc incliné raccordant à cette âme l'autre côté de la tranche de la portion complémentaire.; - ces tranches parallèles ont approximativement la même largeur ; - il est creux avec une épaisseur constante, y compris dans l'aile et l'âme du T. According to preferred arrangements of the invention, possibly combined - it admits a longitudinal plane of symmetry passing through the core of the T, its edge being bordered on both sides by parallel flanks which are perpendicular to it and which connect to this core of the T by two inclined flanks - this lateral flank is coplanar with the core of the T, - an inclined flank connecting to this soul the other side of the edge of the complementary portion .; - these parallel sections have approximately the same width; - it is hollow with a constant thickness, including in the wing and the soul of the T.
L'invention propose également un assemblage par mors de deux tels profilés, c'est à dire une structure métallique boulonnée comportant au moins deux profilés métalliques croisés assujettis l'un à l'autre par des organes de liaison a boulons, caractérisé en ce que chacun de ces profilés métalliques a une section courante comportant une portion conformée en T avec une aile raccordée d'un côté a angle droit a une âme, et une portion complémentaire comportant une tranche parallèle à cette aile et raccordée à angle droit à un flanc latéral s'étendant en direction de l'âme à laquelle il est lui-même raccordé, lesdits profilés étant affrontés tête-bêche par leurs ailes, les organes de liaison comportant deux paires de mors parallèles, chaque paire de mors étant adaptée à coiffer les bords latéraux de l'aile de l'un des profilés, chaque nors de chaque paire étant par ses extre.ites boulonné respectivement à une extrémité de chacun des mors de l'autre paire vis à vis desquels il est disposé en travers. The invention also proposes an assembly by jaws of two such profiles, that is to say a bolted metal structure comprising at least two crossed metal profiles secured to each other by bolt connecting members, characterized in that each of these metal sections has a current section comprising a T-shaped portion with a wing connected on one side at right angles to a core, and a complementary portion comprising a section parallel to this wing and connected at right angles to a lateral flank extending in the direction of the core to which it is itself connected, said sections being faced head to tail by their wings, the connecting members comprising two pairs of parallel jaws, each pair of jaws being adapted to cover the edges lateral of the wing of one of the profiles, each nors of each pair being by its extre.ites bolted respectively to one end of each of the jaws of the be a pair with which it is arranged crosswise.
D'autres modes possibles d'assemblage de ces profilés sont bien sûr possibles par des liaisons boulonnées, voire par soudage. De manière préférée, chacun des mors de chaque paire comporte une portion en équerre coiffant et bordant l'aile du T, et un flanc de fixation, présentant une surface d'affrontement coplanaire à la tranche de cette aile destinée à venir en appui contre la surface d'affrontement du flanc de fixation des mors de l'autre paire. Other possible modes of assembly of these profiles are of course possible by bolted connections, or even by welding. Preferably, each of the jaws of each pair comprises a square portion covering and bordering the wing of the T, and a fixing flank, having a coplanar confrontation surface at the edge of this wing intended to come into abutment against the confrontation surface of the jaw fixing flank of the other pair.

Les figures 1 et 2 représentent un exemple d'application des profilés de l'invention, à savoir, un véhicule de manutention 1 du type camion, équipé d'un dispositif de bennage 2. FIGS. 1 and 2 represent an example of application of the profiles of the invention, namely, a handling vehicle 1 of the truck type, equipped with a tipping device 2.
Le véhicule de manutention 1, de tout type connu approprié, comporte un châssis 3 porté par quatre jeux de roues 4. A l'avant de ce châssis est prévue une cabine 5 ; derrière celle-ci le chassis comporte deux longerons 6. The handling vehicle 1, of any suitable known type, comprises a chassis 3 carried by four sets of wheels 4. At the front of this chassis is a cabin 5; behind it the chassis has two side members 6.
Le dispositif de bennage 2 comporte - un cadre sensiblement rectangulaire 7 - une paire de longerons S disposés sous ce cadre et solidaires de celui-ci - deux bras de bennage 9 montés pivotants sur ce cadre à proximité des coins arrière de celui-ci, en étant articulés autour d'axes transversaux colinéaires - deux vérins de bras 10 respectivement associés à ces bras, disposés près des côtés longitudinaux du cadre et articulés, d'une part pres des coins avant du cadre, d'autre part sur les bras - des éléments de fixation 11 pour l'accrochage à une benne 15 ou 15' disposés aux extrémités supérieures des bras en des zones 12 de ces bras qui sont transversalement en regard, - une barre anti-encastrement 13 disposée transversalement à l'arrière et en contrebas du cadre - des crochets de bennage articulés, schématisés en 14, adaptés selon qu'ils viennent en saillie ou sont effacés, à venir en prise ou non avec l'arête arrière de la benne 15 lorsque celle-ci est déplacée vers l'arrière (leur écartement varie selon le type de la benne considérée). The tipping device 2 comprises - a substantially rectangular frame 7 - a pair of side members S arranged under this frame and integral with it - two tipping arms 9 pivotally mounted on this frame near the rear corners thereof, in being articulated around collinear transverse axes - two arm cylinders 10 respectively associated with these arms, arranged near the longitudinal sides of the frame and articulated, on the one hand near the front corners of the frame, on the other hand on the arms - fastening elements 11 for hooking to a bucket 15 or 15 'arranged at the upper ends of the arms in zones 12 of these arms which are transversely opposite, - an underrun bar 13 disposed transversely at the rear and below of the frame - articulated tipping hooks, shown diagrammatically at 14, adapted according to whether they protrude or are erased, coming into engagement or not with the rear edge of the bucket 15 when the latter is moved backwards (their spacing varies depending on the type of bucket considered).
- des éléments 16 de centrage et de guidage de la benne.- Elements 16 for centering and guiding the bucket.
Les longerons 8 du cadre et des traverses 17 de celui-ci sont ici assujettis les uns aux autres par des organes de liaison 18 à boulons 19, en des zones ajustables de ces longerons et de ces traverses. The side members 8 of the frame and the cross members 17 thereof are here subject to each other by connecting members 18 with bolts 19, in adjustable zones of these side members and these cross members.
Le détail d'une telle liaison apparaît aux figures 3 et 4. The details of such a connection appear in Figures 3 and 4.
Les longerons 8 du cadre sont assujettis, ici par soudage, aux longerons 6 du châssis du véhicule, par l'intermédiaire notamment de plaques de fixation 20. The longitudinal members 8 of the frame are fixed, here by welding, to the longitudinal members 6 of the vehicle chassis, in particular by means of fixing plates 20.
D'autres modes de -liaison sont bien sûr possibles, notamment par boulonnage.Other modes of connection are of course possible, in particular by bolting.
Les longerons 8 et les traverses 17 du cadre ont ici des profils identiques mais inversés. Ils sont creux avec une paroi d'épaisseur constante : cela permet un filage aisé sans vrillage. The side members 8 and the cross members 17 of the frame here have identical but inverted profiles. They are hollow with a wall of constant thickness: this allows easy spinning without twisting.
Le détail de ce profil apparaît à la figure 5. The detail of this profile appears in Figure 5.
La traverse 17 qui est représentée à une partie inférieure 21 conformée en T renversé avec une aile creuse 22 et une âme creuse 23 qui se réduit en pratique à un étranglement
La partie supérieure 24 de cette traverse présente une tranche 25 parallèle à l'aile 22 et de même largeur que celle-ci ; cette tranche se raccorde & angle droit à deux flancs latéraux 26 et 27 orientés vers l'aile 22 et qui sont raccordés à l'âme ou étranglement 23 par des flancs inclinés 28 et 29. The crosspiece 17 which is shown in a lower part 21 shaped as an inverted T with a hollow wing 22 and a hollow core 23 which is reduced in practice to a constriction
The upper part 24 of this crosspiece has a section 25 parallel to the wing 22 and of the same width as the latter; this section is connected at right angles to two lateral flanks 26 and 27 oriented towards the wing 22 and which are connected to the core or throttle 23 by inclined flanks 28 and 29.
Dans l'exemple représenté, la hauteur de la traverse, mesurée perpendiculairement a aile, vaut environ le double de la largeur de l'aile 22, les flancs latéraux ont une hauteur environ égale à la largeur précitée, et la largeur de l'étranglement 23 vaut environ la moitié de la largeur de l'aile. In the example shown, the height of the cross member, measured perpendicularly to the wing, is approximately twice the width of the wing 22, the lateral flanks have a height approximately equal to the aforementioned width, and the width of the constriction 23 is about half the width of the wing.
En pratique l'aile 22 se raccorde à l'étrangle- ment par des surfaces arrière 30 qui sont inclinées par rapport à la surface extérieure de cette aile d'un angle d'environ 10 a 20*, ici d'un angle de 15'. In practice, the wing 22 is connected to the constriction by rear surfaces 30 which are inclined relative to the external surface of this wing by an angle of about 10 to 20 *, here an angle of 15 '.
A titre d'exemple, la traverse fait 80 mm de largeur, 150 mm de haut, pour un étranglement d'environ 40 mm de large et une épaisseur de tôle de 4 mm. For example, the crosspiece is 80 mm wide, 150 mm high, for a constriction of about 40 mm wide and a sheet thickness of 4 mm.
Les organes de liaison 18 assurant l'assuDet- tissement d'un longeron 8 et d'une traverse 17 sont formés de deux paires de mors identiques, à savoir une paire de mors supérieurs parallèles-horizontaux 31 coiffant par au dessus les bords de l'aile 22 de la traverse, et une paire de mors inférieurs parallèles horizontaux 32 coiffant par en dessous les bords de l'aile correspondante du longeron 8. Ces paires de mors sont disposées à angle droit et chaque mors de chaque paire est, en ses extrémités, boulonné sur une extrémité de chacun des mors de l'autre paire. The connecting members 18 ensuring the assuDet- tiation of a spar 8 and a crosspiece 17 are formed of two pairs of identical jaws, namely a pair of parallel-horizontal upper jaws 31 covering from above the edges of the wing 22 of the cross member, and a pair of horizontal parallel lower jaws 32 covering from below the edges of the corresponding wing of the spar 8. These jaw pairs are arranged at right angles and each jaw of each pair is in its ends, bolted to one end of each of the jaws of the other pair.
Chaque mors 31 ou 32 comporte ici une portion en équerre 33 avec une lèvre 34 venant en appui sur les surfaces arrière 30 de l'aile de la traverse ou du longeron, et une âme verticale 35 longeant le bord de l'aile. Cette âme se raccorde å une aile de fixation 36 comportant à distance de cette âme une portée d'appui 37 correspondant à une surépaisseur en sens opposé à l'âme 35. Each jaw 31 or 32 here has a square portion 33 with a lip 34 bearing on the rear surfaces 30 of the wing of the cross member or the spar, and a vertical core 35 along the edge of the wing. This core is connected to a fixing wing 36 comprising, at a distance from this core, a bearing surface 37 corresponding to an additional thickness in the opposite direction to the core 35.
Cette âme et cette aile sont rigidifiées par un voile central 38 et par deux portions massives 39 traversées par des alésages pour le passage de chaque boulon, s'étendant localement sur l'aile, le long de l'âme et sur la lèvre. This core and this wing are stiffened by a central veil 38 and by two massive portions 39 traversed by bores for the passage of each bolt, extending locally on the wing, along the core and on the lip.
Ces alésages traversent l'aile entre la portée d'appui et l'âme centrale 35 grâce à quoi, lors du serrage des boulons, il se produit un effet de bras de levier qui induit une compression des bords de l'aile 22 qui augmente avec le serrage des boulons. Des géométries plus simples pour ces mors sont bien sûr possibles. These bores cross the wing between the bearing surface and the central core 35 whereby, when tightening the bolts, there is a lever arm effect which induces compression of the edges of the wing 22 which increases with the tightening of the bolts. Simpler geometries for these jaws are of course possible.
Ces mors sont moulés. These jaws are molded.
La figure 6 représente un assemblage similaire, avec un profil de la traverse 17' (et du longeron 8') qui diffère de celui des figures 3 à 5 par le fait que la tranche 25', moins large que l'aile 22', se raccorde à un seul flanc perpendiculaire 27', lequel reste plan jusqu'à son raccordement à l'étranglement de l'aile 22'. De l'autre côté, la tranche 25' est raccordée à cette aile par un flanc incliné unique 28'. FIG. 6 represents a similar assembly, with a profile of the cross member 17 ′ (and of the longitudinal member 8 ′) which differs from that of FIGS. 3 to 5 by the fact that the section 25 ′, narrower than the wing 22 ′, is connected to a single perpendicular flank 27 ', which remains flat until it connects to the constriction of the wing 22'. On the other side, the edge 25 'is connected to this wing by a single inclined flank 28'.
Ce profil,plus facile à élaborer que celui des figures 3 à 5, et donc moins coûteux, offre des possibilités d'assemblage par soudure ou par boulonnage/serrage analogues avec une tranche parallèle à l'aile et un flanc qui lui est perpendiculaire. Par contre, ce profil n'a plus la symétrie du profil des figures 3 à 5 par rapport à un plan longitudinal perpendiculaire à l'aile. This profile, easier to develop than that of FIGS. 3 to 5, and therefore less costly, offers possibilities of assembly by welding or by similar bolting / tightening with a section parallel to the wing and a flank which is perpendicular thereto. On the other hand, this profile no longer has the symmetry of the profile of FIGS. 3 to 5 with respect to a longitudinal plane perpendicular to the wing.
Grâce à la possibilité d'ajuster les zones de fixation des traverses aux longerons, un même cadre peut être utilisé sur un grand nombre de châssis de véhicules différents. Thanks to the possibility of adjusting the fixing areas of the crosspieces to the side members, the same frame can be used on a large number of different vehicle chassis.
Il va de soi que la description qui précède n'a été proposée qu'à titre d'exemple non limitatif et que de nombreuses variantes peuvent être proposées par l'homme de l'art sans sortir du cadre de l'invention. Ainsi, par exemple, la liaison boulonnée peut être réalisée grâce à des colliers de serrage boulonnés disposes à 45. It goes without saying that the foregoing description has been offered only by way of nonlimiting example and that numerous variants can be proposed by those skilled in the art without departing from the scope of the invention. Thus, for example, the bolted connection can be achieved by means of bolted clamps arranged at 45.
