Description

Support de garde-corps, notamment pour banche de coffrage.Guardrail support, especially for formwork formwork.

La présente invention concerne un support de garde-corps, notamment pour banche de coffrage, cette banche comportant au moins, comme éléments de sa structure, un longeron supérieur et un longeron inférieur, reliés mutuellement par des montants. The present invention relates to a railing support, in particular for formwork formwork, this formwork comprising at least, as elements of its structure, an upper spar and a lower spar, mutually connected by uprights.

Quand on dresse une paroi verticale (ou inclinée) en béton, on prévoit extérieurement au volume à coffrer des passerelles permettant aux ouvriers de procéder entre les levées successives aux travaux nécessaires, et notamment au montage et au démontage des banches de coffrage et de leurs liaisons. Pour éviter les accidents on prévoit généralement un garde-corps du côté extérieur des passerelles, c'est-à-dire à l'opposé de l'ouvrage, mais il n'y a pas de garde-corps du côté intérieur. En effet, la hauteur de chute possible est moins grande, du fait du levage progressif de l'ouvrage, qui suit celui des passerelles. When erecting a vertical (or inclined) concrete wall, the walkway volume is provided externally allowing walkways allowing workers to carry out the necessary work between successive lifts, and in particular the assembly and disassembly of formwork forms and their connections . To avoid accidents, a railing is generally provided on the outside of the walkways, that is to say opposite the structure, but there is no railing on the inside. Indeed, the possible fall height is less, due to the gradual lifting of the structure, which follows that of the gangways.

Cependant ces chutes peuvent encore être dangereuses, et le but de la présente invention est de remédier à cette lacune de la technique actuelle. However, these falls can still be dangerous, and the object of the present invention is to remedy this deficiency in the current technique.

Ce but est en particulier de permettre le montage ou le démontage rapides et sans outils d'un garde-corps sur le côté intérieur des passerelles, ce garde-corps pouvant être monté directement sur la partie supérieure des banches et être transporté en même temps qu'elles, sans avoir à être démonté. This goal is in particular to allow the rapid assembly and disassembly without tools of a railing on the interior side of the gangways, this railing can be mounted directly on the upper part of the formwork and be transported at the same time as 'them, without having to be dismantled.

Pour résoudre ce problème, un support de gardecorps conforme à la présente invention est essentiellement caractérisé en ce qu'il est constitué d'un poteau comportant à sa partie supérieure un taquet de réception du garde-corps et, à sa partie inférieure, d'une part un pied en U s'ouvrant latéralement et propre à s'engager sur ledit longeron supérieur de la structure de ladite banche, et d'autre part un crochet s'ouvrant latéralement en sens inverse et propre à s'engager sur la partie supérieure d'un desdits montants. To solve this problem, a railing support in accordance with the present invention is essentially characterized in that it consists of a post comprising at its upper part a catch for receiving the railing and, at its lower part, on the one hand a U-shaped foot opening laterally and suitable for engaging on said upper spar of the structure of said form, and on the other hand a hook opening laterally in opposite direction and suitable for engaging on the part one of the said amounts.

On verra plus facilement plus bas, à la lecture d'un mode de réalisation décrit avec référence au dessin, comment un tel support peut être rapidement et simplement monté à la partie supérieure d'une banche de coffrage, et ceci sans aucun outil. We will see more easily below, on reading an embodiment described with reference to the drawing, how such a support can be quickly and simply mounted to the upper part of a formwork formwork, and this without any tool.

Un tel support pourra encore être caractérisé en ce que ledit crochet est fixé à l'aile inférieure dudit pied en U. Such a support can also be characterized in that said hook is fixed to the lower wing of said U-shaped foot.

Le poteau pourra être constitué d'un tube à section transversale carrée, tandis que le taquet et le crochet pourront être constitués chacun d'un fer rond coudé. The post may consist of a square cross-section tube, while the cleat and the hook may each consist of a bent round iron.

On voit qu'un tel support pourra être constitué d'éléments de construction classiques, extrêmement simples. It is seen that such a support could consist of conventional, extremely simple construction elements.

Un support conforme à l'invention pourra encore se caractériser en ce que ledit taquet comporte une base soudée non loin de l'extrémité supérieure dudit poteau, cette base étant suivie d'une branche s'étendant vers le haut parallèlement audit poteau et à une distance de celui-ci légèrement supérieure à l'épaisseur du gardecorps. A support according to the invention may also be characterized in that said cleat comprises a welded base not far from the upper end of said post, this base being followed by a branch extending upward parallel to said post and to a distance from it slightly greater than the thickness of the railing.

Quant au pied en U, il pourra être simplement fixé à la base dudit poteau par soudage avec son aile supérieure, de même que ledit crochet pourra être fixé à l'aile inférieure dudit pied en U par soudage. As for the U-shaped foot, it can be simply fixed to the base of said post by welding with its upper wing, just as said hook can be fixed to the lower wing of said U-shaped foot by welding.

Avantageusement, on peut encore prévoir que les ailes dudit pied en U sont parallèles l'une à l'autre et s'étendent perpendiculairement à l'axe dudit poteau. Advantageously, provision can also be made for the wings of said U-shaped foot to be parallel to each other and to extend perpendicular to the axis of said post.

Quant audit crochet, il pourra s'étendre dans le plan de l'aile inférieure dudit pied en U, en ménageant près de celle-ci un espace d'une largeur légèrement supérieure à l'épaisseur desdits montants des banches.  As for said hook, it may extend in the plane of the lower wing of said U-shaped foot, leaving a space near it a width slightly greater than the thickness of said uprights of the formwork.

Ainsi il y aura très peu de jeu entre le support de garde-corps et la banche, de même qu'entre le gardecorps lui-même et son taquet de retenue. Thus there will be very little play between the railing support and the cover, as well as between the railing itself and its retaining cleat.

Un mode d'exécution de l'invention va maintenant être décrit à titre d'exemple nullement limitatif, avec référence aux figures du dessin annexé dans lequel
- la figure 1 est une vue en élévation de profil d'un support conforme à l'invention
- la figure 2 est une vue en élévation de face du même support
- la figure 3 est une vue de dessus de ce support ; et
- la figure 4 est une vue en élévation de deux supports conformes à 1 invention portant un garde-corps et montés sur une banche de coffrage.
An embodiment of the invention will now be described by way of non-limiting example, with reference to the figures of the accompanying drawing in which
- Figure 1 is a side elevational view of a support according to the invention
- Figure 2 is a front elevational view of the same support
- Figure 3 is a top view of this support; and
- Figure 4 is an elevational view of two supports according to 1 invention carrying a railing and mounted on a formwork form.

Sur les différentes figures, le poteau constitué d'un tube à section carrée est référencé en 1, le pied constitué d'une section de fer en U est référencé en 2 et le taquet de réception du garde-corps est référencé en 3. Le pied 2 en U est soudé par son aile supérieure 2a à la base du poteau 1, de sorte que l'axe du poteau soit perpendiculaire au plan des deux ailes parallèles 2a et 2b de ce pied. Sur l'aile inférieure 2b est soudé un crochet 4 s'ouvrant latéralement en sens inverse par rapport à l'ouverture du pied 2 en U.Le crochet 4 est constitué d'un fer rond coudé à angle droit et s'étend dans le plan de l'aile inférieure 2b du pied en U, de sorte à ménager près de celle-ci un espace de largeur e légèrement supérieure à l'épaisseur des montants 5 des banches de coffrage 11, lesquels montants relient, comme cela est visible sur la figure 4, un longeron supérieur 6 et un longeron inférieur 7 de la banche 11, lesquels longerons sont reliés par ailleurs par des éléments de structure latéraux 8 et central 9. In the various figures, the post consisting of a tube with a square section is referenced in 1, the foot consisting of a U-shaped iron section is referenced in 2 and the catch for receiving the railing is referenced in 3. The foot 2 in U is welded by its upper wing 2a to the base of the post 1, so that the axis of the post is perpendicular to the plane of the two parallel wings 2a and 2b of this foot. On the lower wing 2b is welded a hook 4 opening laterally in opposite direction relative to the opening of the foot 2 in U. The hook 4 consists of a round iron bent at right angles and extends in the plane of the lower wing 2b of the U-shaped foot, so as to provide near it a space of width e slightly greater than the thickness of the uprights 5 of the formwork forms 11, which uprights connect, as can be seen on FIG. 4, an upper spar 6 and a lower spar 7 of the panel 11, which spars are also connected by lateral 8 and central 9 structural elements.

Quant au taquet 3, il est lui également constitué d'un fer rond coudé à angle 3, comportant une base 3a soudée sur le poteau et une branche 3b s'étendant vers le haut et parallèlement au poteau, de sorte qu'un espace de largeur d soit ménagé entre ce poteau et ladite branche 3b, cet espace étant légèrement supérieur à l'épaisseur des garde-corps 10. As for the cleat 3, it also consists of a bent round iron at an angle 3, comprising a base 3a welded to the post and a branch 3b extending upward and parallel to the post, so that a space for width d is formed between this post and said branch 3b, this space being slightly greater than the thickness of the railings 10.

Ceci étant, on voit qu'il sera très facile de monter de tels supports sur le longeron supérieur 6 d'une banche de coffrage 11 telle que celle qui a été représentée à la figure 4 : il suffira en effet de saisir le poteau 1 et d'engager son pied 2 en U sur ledit longeron supérieur 6 et ceci en faisant légèrement pivoter le poteau sur son axe pour permettre au crochet inférieur 4 de passer derrière la partie supérieure du montant correspondant 5. Ensuite il suffit de faire pivoter le poteau dans le sens inverse pour que le crochet 4 vienne se bloquer derrière cette partie supérieure du montant 5, le taquet 3 s'étendant alors dans un plan perpendiculaire à celui que devra occuper le garde-corps 10. Un deuxième support étant posé sur la même banche au niveau de l'autre montant 5, le gardecorps 10 sera lui aussi très facilement mis en place par insertion dans les taquets 3 des deux supports. On voit qu'il n'y a besoin d'aucun outil pour procéder à cette opération et que bien entendu le démontage du gardecorps et des supports pourra s'effectuer de même sans aucun outillage. Cependant, il est à noter qu'il ne sera pas nécessaire de démonter le garde-corps à chaque fois que l'on aura à transférer la banche : on pourra parfaitement transporter la banche avec son système de supports et de garde-corps maintenu en place. That said, it can be seen that it will be very easy to mount such supports on the upper spar 6 of a formwork panel 11 such as that which has been shown in FIG. 4: it will suffice to grasp the post 1 and to engage its foot 2 in U on said upper spar 6 and this by slightly pivoting the post on its axis to allow the lower hook 4 to pass behind the upper part of the corresponding amount 5. Then just rotate the post in the opposite direction so that the hook 4 comes to hang behind this upper part of the upright 5, the cleat 3 then extending in a plane perpendicular to that which the railing should occupy 10. A second support being placed on the same branch at the other upright 5, the bodyguard 10 will also very easily be inserted by insertion into the cleats 3 of the two supports. We see that there is no need for any tool to carry out this operation and that of course the disassembly of the railing and the supports can be done in the same way without any tools. However, it should be noted that it will not be necessary to dismantle the railing each time we have to transfer the canvas: we can perfectly transport the canvas with its system of supports and railing maintained in square.

En effet, tant que le garde-corps est en place, on voit que les supports ne peuvent pivoter sur le longeron supérieur 6 de la banche, du fait de l'accrochage du crochet 4 sur le montant correspondant 5 et du fait également que ce crochet et le pied 2 en U s'ouvrent latéralement en sens inverse l'un de l'autre ; ce n'est qu'après extraction volontaire du garde-corps 10 que l'on pourra, si besoin est, faire pivoter les supports pour les dégager des montants correspondants 5 et les retirer de la banche 11. Indeed, as long as the railing is in place, it can be seen that the supports cannot pivot on the upper side member 6 of the formwork, owing to the hooking of the hook 4 on the corresponding upright 5 and also because hook and foot 2 in U open laterally in opposite directions to each other; it is only after voluntary removal of the railing 10 that it will be possible, if necessary, to pivot the supports to release them from the corresponding uprights 5 and remove them from the panel 11.

Il est à souligner également que les supports conformes à l'invention seront d'un prix de revient très réduit et pourront être facilement fabriqués en grandes séries.  It should also be emphasized that the supports in accordance with the invention will be of a very reduced cost price and can be easily produced in large series.
