Abstract

The walkway consists of two side members, e.g. in the form of aluminium extrusions, assembled without welding with decking members (2) and two end cross-members. Each of the side members has a recess (4) at the bottom to receive the ends of the decking members, one part of the recess having a projecting rib (13) to engage with a matching groove (14) in the decking member. Each of the end cross-members holds the decking members in place and is fixed to one end of the side members by bolts or cables inserted into lengthwise tubular reinforcements (6, 7) running the length of the side members.

Description

La présente invention concerne la réalisation de planchers pour des passerelles et plus particulièrement des passerelles suspendues.The present invention relates to the production of floors for walkways and more particularly suspended walkways.

On connait des structures constituant des passerelles suspendues, notamment pour les travaux sur chantiers. Ces passerelles sont généralement formées de divers éléments assemblés sur place dont chacun est constitué de composants soudés.We know structures constituting suspended walkways, especially for work on construction sites. These gangways are generally made up of various elements assembled on site, each of which consists of welded components.

Ces éléments comprennent principalement, pour chaque unité de passerelle :

  • un plancher,
  • deux garde-corps,
  • des étriers de suspension.
These elements mainly include, for each bridge unit:
  • a floor,
  • two railings,
  • suspension brackets.

La présente invention a pour objet de réaliser un plancher pour une telle passerelle, qui soit constitué sans soudure afin d'en diminuer le coût, d'en simplifier le montage, et d'éviter les contraintes techniques de la soudure. En effet, les structures concernées sont avantageusement réalisées en aluminium, étant donné le gain de poids obtenu par l'emploi de ce matériau.The object of the present invention is to produce a floor for such a gangway, which is made without welding in order to reduce the cost, to simplify assembly, and to avoid the technical constraints of welding. Indeed, the structures concerned are advantageously made of aluminum, given the weight gain obtained by the use of this material.

Or, spécialement pour l'aluminium, la technique de la soudure a des conséquences gênantes et coûteuses. L'opération de soudure entraîne sur la zone concernée un effet de recuit neutralisant partiellement mais notablement l'amélioration de limite élastique obtenue par traitement thermique de la qualité d'aluminium utilisée à cette fin.Now, especially for aluminum, the welding technique has troublesome and costly consequences. The welding operation results in an annealing effect on the zone concerned partially but notably neutralizing the improvement in elastic limit obtained by heat treatment of the quality of aluminum used for this purpose.

L'abaissement de la limite élastique qui en résulte nécessite de dimensionner plus largement les composants utilisés, d'où une augmentation de coût.The lowering of the resulting elastic limit necessitates a larger dimensioning of the components used, hence an increase in cost.

Par ailleurs toute soudure entraîne une aggravation des risques de corrosion et nécessite, pour limiter ces risques, une procédure de contrôle qualité stricte et coûteuse, à quoi s'ajoute le coût d'un personnel qualifié.In addition, any weld increases the risk of corrosion and requires, to limit these risks, a strict and costly quality control procedure, to which is added the cost of qualified personnel.

Selon l'invention, un plancher modulaire de passerelle se caractérise en ce qu'il est composé par l'assemblage sans soudure de deux plinthes, d'un ensemble d'éléments de base et de deux traverses d'extrémité, les dites plinthes étant constituées par des profilés qui comportent chacun un profil latéral recevant les extrémités latérales des éléments de base, lequel profil latéral présente, suivant un mode préférentiel, au moins une partie en saillie s'insérant dans au moins une entaille correspondante de ces éléments de base en faisant participer ceux-ci à la rigidité transversale de la passerelle, les traverses d'extrémité étant fixées en bout des plinthes par au moins un point de fixation sur chaque plinthe en assurant la cohérence de l'ensemble.According to the invention, a modular walkway floor is characterized in that it is composed by the seamless assembly of two plinths, a set of base elements and two end crosspieces, said plinths being constituted by profiles which each have a lateral profile receiving the lateral ends of the basic elements, which lateral profile has, according to a preferred embodiment, at least one projecting part fitting into at least one corresponding notch of these basic elements in involving these in the transverse rigidity of the gangway, the end crosspieces being fixed at the end of the plinths by at least one fixing point on each plinth, ensuring the consistency of the assembly.

Chaque profilé de plinthe comporte au moins un profil latéral longitudinal inférieur creux qui sert de logement à un élément destiné à relier la plinthe aux deux traverses d'extrémité ou à d'autres parties de la passerelle.Each plinth profile has at least one hollow lower longitudinal side profile which serves as a housing for an element intended to connect the plinth to the two end crosspieces or to other parts of the gangway.

Ce profil latéral est disposé de préférence du côté extérieur à la passerelle et, s'il est unique, à la partie inférieure de la plinthe. Il est creux et peut avoir de préférence, mais non nécessairement, une section tubulaire fermée.This lateral profile is preferably arranged on the outside of the gangway and, if it is unique, at the bottom of the plinth. It is hollow and may preferably, but not necessarily, have a closed tubular section.

Selon une forme de réalisation le profil reçoit dans ce cas, à chaque extrémité et sur une longueur appropriée, un taraudage destiné à accueillir une vis pour le relier à l'élément transversal d'extrémité correspondant, ainsi qu'éventuellement à un jambage de garde-corps disposé au-dessus de la dite plinthe.According to one embodiment, the profile receives in this case, at each end and over an appropriate length, a tapping intended to receive a screw to connect it to the corresponding end transverse element, as well as possibly to a guard jamb. -body arranged above said plinth.

Suivant une réalisation alternative une tige, filetée au moins à ses extrémités, est passée dans le dit profil sur toute la longueur de celui-ci et dépasse à chaque extrémité pour servir de liaison par écrou comme il est dit ci-dessus.According to an alternative embodiment, a rod, threaded at least at its ends, is passed through said profile over the entire length thereof and protrudes at each end to serve as a nut connection as described above.

Selon une réalisation préférée, les écrous situés aux deux extrémités de la tige filetée sont serrés contre les extrémités du profil creux pour placer la plinthe en situation de précontrainte. Ce serrage peut s'effectuer par l'intermédiaire des éléments transversaux d'extrémité préalablement mis en place.According to a preferred embodiment, the nuts located at the two ends of the threaded rod are tightened against the ends of the hollow profile to place the baseboard in a prestressed situation. This tightening can be carried out by means of the transverse end elements previously put in place.

Comme alternative, la tige filetée peut être remplacée par un câble sur les extrémités duquel sont fixées des attaches permettant un blocage équivalent, avec le même effet de précontrainte.As an alternative, the threaded rod can be replaced by a cable on the ends of which are fastened clips allowing an equivalent blocking, with the same prestressing effect.

Le profil creux situé à la partie inférieure de la plinthe peut être doublé d'un profil creux parallèle situé à la partie supérieure de la plinthe et permettant de renforcer l'effet de liaison du premier profil..The hollow profile located at the bottom of the plinth can be lined with a parallel hollow profile located at the top of the plinth and making it possible to reinforce the bonding effect of the first profile.

Une fois assemblé l'ensemble décrit ci-dessus constitue un ensemble de plancher rigide obtenu sans soudure de ses composants qui est susceptible notamment d'être relié à des garde-corps et étriers pour former une passerelle, et notamment une passerelle suspendue. Cet ensemble permet de réaliser en outre, de façon simple, la précontrainte de la passerelle.Once assembled, the assembly described above constitutes a rigid floor assembly obtained without welding of its components which is in particular capable of being connected to railings and stirrups to form a gangway, and in particular a suspended gangway. This assembly also makes it possible, in a simple manner, to preload the bridge.

En référence au dessin, le plancher selon l'invention est constitué de deux plinthes latérales 1, d'une série d'éléments transversaux modulaires 2 constituant la base du plancher, et de deux éléments transversaux d'extrémité 3. La figure 1 montre la disposition respective de ces éléments en vue de leur assemblage.With reference to the drawing, the floor according to the invention consists of two lateral plinths 1, of a series of modular transverse elements 2 constituting the base of the floor, and of two transverse end elements 3. FIG. 1 shows the respective arrangement of these elements with a view to their assembly.

Chaque plinthe 1 est conçue de façon à constituer, en association avec l'autre plinthe, un élément de liaison des éléments transversaux de base 2 entre eux et entre les éléments transversaux de base 2 et les deux éléments transversaux d'extrémité 3. A cet effet, comme on le voit en particulier à la figure 4, chaque plinthe 1 est constituée par un profilé qui comporte, vers l'intérieur, un profil latéral longitudinal inférieur creux 4 destiné à servir de logement à l'extrémité latérale 5 des éléments de base 2 en calant ceux-ci vers le haut comme vers le bas. On comprend que les éléments transversaux de base 2 sont engagés longitudinalement par glissement dans les dits profils latéraux 5 des plinthes 1.Each plinth 1 is designed so as to constitute, in association with the other plinth, a connecting element for the basic transverse elements 2 between them and between the basic transverse elements 2 and the two transverse end elements 3. For this purpose, as can be seen in particular in FIG. 4, each plinth 1 is constituted by a profile which comprises, towards the inside , a hollow lower longitudinal side profile 4 intended to serve as a housing at the lateral end 5 of the base elements 2 by wedging them upwards as well as downwards. It is understood that the basic transverse elements 2 are engaged longitudinally by sliding in the said lateral profiles 5 of the plinths 1.

Vers l'extérieur, le profilé de plinthe 1 présente deux profils latéraux longitudinaux creux parallèles entre eux, dont l'un 6 est disposé à la partie inférieure et dont l'autre 7 est disposé à la partie supérieure du profilé.To the outside, the plinth profile 1 has two hollow longitudinal side profiles which are parallel to one another, one of which 6 is disposed at the bottom and the other 7 of which is disposed at the top of the profile.

Chaque profil 6,7 reçoit, à ses deux extrémités 8,9 et sur une longueur appropriée, un taraudage destiné à accueillir une vis 10.Each profile 6,7 receives, at its two ends 8,9 and over an appropriate length, a thread intended to receive a screw 10.

Chacun des éléments transversaux de base 2 est constitué par une tôle métallique dont les bords transversaux 11 sont repliés pour prendre une forme en U, alors que ses bords latéraux 5 sont destinés à s'engager et coulisser dans les profils intérieurs 4 des plinthes 1.Each of the basic transverse elements 2 is constituted by a metal sheet whose transverse edges 11 are folded back to take a U shape, while its lateral edges 5 are intended to engage and slide in the interior profiles 4 of the plinths 1.

Comme on le voit plus particulièrement à la figure 4, le profil intérieur 4 de chaque plinthe 1 présente sur sa face inférieure des saillies 13 destinées à s'engager dans des entailles correspondantes 14 ménagées dans la partie inférieure des éléments de base 2 de façon que l'ensemble des éléments de base 2 coopère sur toute sa longueur à la liaison des deux côtés du plancher.As seen more particularly in Figure 4, the inner profile 4 of each plinth 1 has on its underside projections 13 intended to engage in corresponding notches 14 formed in the lower part of the base elements 2 so that all the basic elements 2 cooperate over its entire length at the connection of the two sides of the floor.

Les deux éléments transversaux d'extrémité 3 relient sans soudure les deux plinthes 1 à chacune de leurs extrémités. Ces éléments transversaux d'extrémité 3 présentent une forme en U dont les branches permettent une liaison rigide avec les garde-corps et les plinthes. Comme représenté à la figure 2, cette liaison est assurée par les vis 10 traversant des ouvertures appropriées 15 des branches de l'élément transversal d'extrémité et se vissant dans les extrémités taraudées 8,9 des profils 6,7 de chaque plinthe 1.The two transverse end elements 3 seamlessly connect the two plinths 1 at each of their ends. These transverse end elements 3 have a U-shape, the branches of which allow a rigid connection with the railings and the plinths. As shown in FIG. 2, this connection is ensured by the screws 10 passing through appropriate openings 15 of the branches of the transverse end element and being screwed into the threaded ends 8,9 of the profiles 6,7 of each plinth 1.

Selon une variante, non représentée au dessin, la liaison entre les plinthes et les éléments transversaux d'extrémité n'est pas assurée par des vis, mais par une tige filetée ou un câble passant dans chaque profil de la plinthe et dont le blocage à chacune de ses extrémités permet d'exercer sur la plinthe un effet de pré-contrainte.According to a variant, not shown in the drawing, the connection between the baseboards and the transverse end elements is not ensured by screws, but by a threaded rod or a cable passing through each profile of the baseboard and whose blocking at each of its ends makes it possible to exert a pre-stress effect on the plinth.

L'ensemble de plancher ainsi assemblé représenté à la figure 5, constitue un ensemble rigide obtenu sans soudure, et qui est susceptible d'être relié à des garde-corps et étriers pour former une passerelle suspendue.The floor assembly thus assembled, shown in FIG. 5, constitutes a rigid assembly obtained without welding, and which is capable of being connected to railings and stirrups to form a suspended gangway.

A la figure 6 on a représenté le plancher assemblé, qui a reçu une paire de garde-corps 16 figurés en pointillé. Comme on le voit le jambage 17 du garde-corps est fixé par la vis 10 solidarisant l'élément transversal d'extrémité 3 et la plinthe 1.In Figure 6 there is shown the assembled floor, which has received a pair of railings 16 shown in dotted lines. As can be seen, the jamb 17 of the railing is fixed by the screw 10 joining the transverse end element 3 and the plinth 1.

A la figure 7 on a représenté une variante selon laquelle les éléments transversaux d'extrémité 3 en forme de U sont prolongés vers le haut pour améliorer leur liaison avec les garde-corps 16 et former des étriers permettant la jonction entre plusieurs modules de passerelle.In FIG. 7, a variant is shown according to which the U-shaped transverse end elements 3 are extended upwards to improve their connection with the railings 16 and to form stirrups allowing the junction between several gangway modules.

L'un au moins des éléments transversaux d'extrémité 3 pourrait aussi être prolongé vers le haut pour former un étrier de suspension (non représenté).At least one of the transverse end elements 3 could also be extended upwards to form a suspension bracket (not shown).

Afin de permettre une liaison longitudinale du plancher selon l'invention avec les garde-corps 16 d'une passerelle, on prévoit (voir en particulier les figures 4 et 8) à la partie supérieure de chaque plinthe 1 un profil d'accrochage 18 qui coopère avec un profil correspondant 19 prévu dans la lisse inférieure 20 du garde-corps 16. Dans ce cas, les jambages d'extrémité du garde-corps sont fixés sur les branches correspondantes des traverses d'extrémité, comme on l'a décrit en référence à la figure 6.In order to allow a longitudinal connection of the floor according to the invention with the railings 16 of a gangway, there is provided (see in particular Figures 4 and 8) at the upper part of each plinth 1 an attachment profile 18 which cooperates with a corresponding profile 19 provided in the bottom rail 20 of the railing 16. In this case, the end legs of the railings are fixed on the corresponding branches of the end crosspieces, as described with reference to Figure 6.

Enfin, selon une variante représentée à la figure 9, les profils extérieurs latéraux 6,7 de la plinthe 1 sont configurés de façon à présenter des parties en regard 21 formant glissières qui permettent d'encastrer par glissement entre les deux profils une plaque (non figurée au dessin) portant des inscriptions ou servant de support à des accessoires.Finally, according to a variant represented in FIG. 9, the lateral external profiles 6, 7 of the plinth 1 are configured so as to present facing parts 21 forming slides which allow a plate to be fitted by sliding between the two profiles (not shown in the drawing) bearing inscriptions or serving as a support for accessories.

On comprendra que la description ci-dessus a été donnée à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de l'invention.It will be understood that the above description has been given by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the invention.
