Description

La présente invention concerne le domaine de la fabrication de matériel d'échafaudage et a pour objet un panneau garde-corps de sécurité pour échafaudage, selon le préambule de la revendication 1 (FR-A-2 533 610)The present invention relates to the field of manufacturing scaffolding equipment and relates to a safety railing panel for scaffolding, according to the preamble of claim 1 (FR-A-2 533 610)

Actuellement, les échafaudages, constitués par des échelles d'ossature porteuse, par des planchers et par des garde-corps sont généralement montés par niveau complet, c'est-à-dire par pose du plancher du niveau supérieur, puis par mise en place des échelles, les garde-corps étant fixés sur les échelles en dernier lieu.Currently, scaffolding, consisting of load-bearing framework ladders, floors and railings are generally erected by complete level, that is to say by laying the floor of the upper level, then by placing ladders, the railings being fixed on the ladders last.

Ce procédé de montage des échafaudages existants présente, cependant, l'inconvénient de faire courir un risque de chute grave à l'opérateur lors de la mise en place des échelles du niveau supérieur, en particulier suite à une perte d'équilibre due au poids desdites échelles qui doivent être manutentionnées verticalement. En effet, les garde-corps ne peuvent être montés qu'après mise en place des échelles du fait de leur fixation directement sur ces dernières.This method of mounting existing scaffolding has, however, the disadvantage of running a risk of serious fall to the operator during the installation of ladders of the upper level, in particular following a loss of balance due to the weight said ladders which must be handled vertically. Indeed, the railings can only be mounted after the installation of ladders due to their fixing directly on the latter.

La présente invention a pour but de pallier ces inconvénients par les mesures de la partie caractérisante de la revendication 1.The object of the present invention is to overcome these drawbacks by the measures of the characterizing part of claim 1.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels:

  • la figure 1 est une vue en perspective montrant le montage d'un garde-corps conforme à l'invention ;
  • la figure 2 est une vue analogue à celle de la figure 1 représentant le montage d'une échelle, et
  • la figure 3 est une vue en élévation latérale, à plus grande échelle, du garde-corps.
The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a perspective view showing the mounting of a railing according to the invention;
  • FIG. 2 is a view similar to that of FIG. 1 showing the mounting of a ladder, and
  • Figure 3 is a side elevational view, on a larger scale, of the railing.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 à 3 des dessins annexés, le panneau garde-corps de sécurité pour échafaudage, qui présente une forme générale en U inversé 1 à ailes courtes et à âme allongée, dont les ailes sont reliées entre elles par des entretoises de rigidification 2 et 3 et sont munies chacune d'une patte 4 de fixation à des tenons d'assemblage 5 des échelles d'échafaudage 6, est caractérisé en ce que les pattes de fixation 4 sont montées aux extrémités des ailes du U 1 et coopèrent avec des tenons d'assemblage 5 prévus sur le côté intérieur des montants des échelles 6 sous le niveau du plancher 7, qui correspond au garde-corps. Les ailes du U 1 sont pourvues, en outre, d'une part, au-dessus du niveau du plancher 7, de moyens 8 d'accrochage d'une plinthe 9, et, d'autre part, à proximité de l'âme, de pattes 10 munies chacune d'un évidement 11 tourné vers le haut, destiné à coopérer avec des tenons 12 des échelles 6.According to the invention, and as shown more particularly, by way of example, Figures 1 to 3 of the accompanying drawings, the safety railing panel for scaffolding, which has a general inverted U shape 1 with short wings and with an elongated core, the wings of which are connected to each other by stiffening spacers 2 and 3 and are each provided with a lug 4 for attachment to assembly studs 5 of the scaffolding ladders 6, is characterized in that the fixing lugs 4 are mounted at the ends of the wings of the U 1 and cooperate with assembly studs 5 provided on the inside of the uprights of the ladders 6 below the level of the floor 7, which corresponds to the railing. The wings of the U 1 are further provided, on the one hand, above the level of the floor 7, with means 8 for hooking a plinth 9, and, on the other hand, near the core , of legs 10 each provided with a recess 11 turned upwards, intended to cooperate with tenons 12 of the scales 6.

Les moyens 8 d'accrochage d'une plinthe 9 sont avantageusement sous forme d'anses allongées s'étendant horizontalement en saillie vers l'extérieur des ailes du U 1 et s'appuyant intérieurement contre la partie du montant de l'échelle de l'étage inférieur, dépassant au-dessus du niveau du plancher 7 correspondant, lors de la pose du garde-corps.The means 8 for hooking a plinth 9 are advantageously in the form of elongated handles projecting horizontally projecting outwards from the wings of the U 1 and pressing internally against the part of the upright of the ladder of l 'lower floor, protruding above the level of the corresponding floor 7, when installing the railing.

Ainsi, après mise en place d'un étage d'échafaudage, un garde-corps conforme à l'invention est monté entre chaque paire d'échelles du côté du vide, et, éventuellement, du côté façade, ou en console suivant les cas par emboîtement des pattes 4 sur les tenons 5 prévus à l'intérieur des montants ou des consoles des échelles 6. Le maintien contre un basculement de trop forte amplitude vers l'extérieur est assuré par les moyens 8 qui s'appuient contre la partie correspondante du montant d'échelle dépassant le niveau du plancher 7 correspondant et servant à l'emboîtement de l'échelle de l'étage supérieur.Thus, after the installation of a scaffolding stage, a railing according to the invention is mounted between each pair of ladders on the vacuum side, and possibly on the facade side, or in a console, depending on the case, by fitting the tabs 4 onto the studs 5 provided inside the uprights or the consoles of the ladders 6. Maintaining against a tilting of too great amplitude towards the outside is ensured by the means 8 which are pressed against the corresponding part of the amount of ladder exceeding the level of the corresponding floor 7 and serving for the nesting of the ladder of the floor superior.

Après mise en place de tous les garde-corps, le plancher 7 de l'étage supérieur est posé de manière connue en soi, et les échelles de support de l'étage supérieur sont emboîtées sur les parties dépassantes de montants et en réalisant la coopération des évidements 11 des pattes 10 du garde-corps avec les tenons correspondants 12 des échelles 6. Enfin, les plinthes 9 sont mises en place par montage sur les moyens d'accrochage 8. A cet effet, les plinthes 9 sont avantageusement pourvues à leurs extrémités de crochets 13 d'accrochage destinés à coopérer avec les moyens 8 en forme d'anses.After all the railings have been put in place, the floor 7 of the upper floor is laid in a manner known per se, and the support ladders of the upper floor are fitted onto the protruding parts of the uprights and making the cooperation recesses 11 of the legs 10 of the railing with the corresponding tenons 12 of the ladders 6. Finally, the plinths 9 are put in place by mounting on the hooking means 8. For this purpose, the plinths 9 are advantageously provided with their ends of hooking hooks 13 intended to cooperate with the means 8 in the form of handles.

Les tenons 12 des échelles 6 coopèrant avec les évidements 11 des pattes 10 sont, soit sous forme de tenons munis de cliquets de blocage, soit sous forme de crochets recouvrant les pattes 10 en position montée des échelles.The pins 12 of the scales 6 cooperating with the recesses 11 of the legs 10 are either in the form of pins provided with locking pawls, or in the form of hooks covering the legs 10 in the mounted position of the scales.

Grâce à l'invention, il est possible de réaliser un garde-corps pouvant être posé en toute sécurité à partir du niveau inférieur, et permettant une protection totale du personnel pendant la pose des échelles de l'ossature porteuse de l'échafaudage, du fait qu'il est déjà en place lors de cette dernière pose.Thanks to the invention, it is possible to produce a guardrail which can be placed safely from the lower level, and allowing total protection of the personnel during the installation of the ladders of the supporting frame of the scaffolding, fact that it is already in place during this last pose.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, sans sortir pour autant du domaine de protection de l'invention, défini par les revendications.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, without thereby departing from the scope of protection of the invention, defined by the claims.
