Definitions
- the present invention relates to a metal console for carrying out various scaffolding and, in particular, light scaffolding such as concrete walkways.
- the present invention aims to eliminate these drawbacks.
- this objective is achieved by means of a metal console comprising a carrying element executed in a manner known per se and comprising a support arm intended to support the boards constituting the decking of the scaffolding, and a clamping flange serving to wedge said boards between said flange and said support arm,
- this metal console being remarkable in that the flange is formed by a clamping bar secured to a plurality of threaded rods spaced apart and oriented perpendicular to said bar to which they are rigidly attached via one of their ends, in that the support arm is provided with holes and in that the spacing of these threaded rods is identical to that of said holes, so that they can be engaged in these, through the interstices reserved between the decking boards, and receive a nut whose tightening allows to wedge strongly said boards between said clamping bar and said support arm.
- the decking boards can be immobilized firmly in position, convenient and quick, without the need to drill holes in said boards beforehand.
- the device according to the invention consists of a reduced number of parts. Its cost is low and its implementation economical because it can be carried out quickly by a single operator who first installs the two clamps, then passes below the gangway to screw and tighten the nuts. As soon as a clamp has been positioned, the planks can no longer move apart and the decking can no longer tilt around the console support arm. The installation of the device according to the invention can therefore take place under better security conditions.
- the metal console according to the invention comprises a support element 1 produced in a manner known per se and essentially comprising a support arm 1a and a strut 1b assembled by a spacer 1c and the free ends of which are provided with fixing means 1d, 1e (hooking shoes, etc. ), respectively.

Abstract
Description
La présente invention concerne une console métallique pour l'exécution d'échafaudages divers et, notamment, d'échafaudages légers tels que passerelles de bétonnage.The present invention relates to a metal console for carrying out various scaffolding and, in particular, light scaffolding such as concrete walkways.
Elle vise également les passerelles de bétonnage et autres échafaudages légers réalisés au moyen de cette console.It also targets concrete walkways and other light scaffolding made using this console.
On connaît (GB-A-2.167.488) des dispositifs permettant de fixer les planches du platelage des passerelles de bétonnage sur les bras-supports tubulaires des consoles métalliques prévues pour soutenir ce platelage, sans nécessiter un percement préalable desdites planches. Ces dispositifs comprennant:
- ― une barre perforée destinée à être posée transversalement sur l'ensemble des planches légèrement espacées constituant le platelage et reposant sur les bras-supports des consoles métalliques,
- ― des crochets latéralement munis d'écrous formés d'une seule pièce avec lesdits crochets ou non, et appelés à être accrochés sur la face inférieure des bras-supports,
- ― et des vis destinées à traverser les ouvertures de la barre et les interstices réservés entre les planches, et à se visser dans lesdits écrous, de manière à réaliser un serrage énergique des planches, entre la barre de serrage et les bras-supports des consoles.
- - a perforated bar intended to be placed transversely on all of the slightly spaced planks constituting the decking and resting on the support arms of the metal consoles,
- - hooks laterally provided with nuts formed in one piece with said hooks or not, and called to be hung on the underside of the support arms,
- - And screws intended to cross the openings of the bar and the interstices reserved between the boards, and to be screwed into said nuts, so as to achieve a forceful tightening of the boards, between the clamping bar and the support arms of the consoles .
Ces dispositifs sont toutefois affectés d'un certain nombre d'inconvénients.These devices are however affected by a number of drawbacks.
L'un de ces inconvénients découle du fait qu'ils sont composés d'un assez grand nombre de pièces, ce qui favorise les risques de perte sur les chantiers. Ils sont en outre relativement coûteux. Un autre inconvénient de ces dispositifs réside dans le fait que leur mise en place nécessite l'intervention d'au moins deux exécutants et s'effectue dans des conditions de sécurité très précaires. En effet, il est indispensable que l'un des exécutants se tienne au-dessous du platelage pour positionner et tenir successivement les crochets, pendant qu'un deuxième exécutant se trouvant sur le platelage procède au vissage des vis dans les écrous desdits crochets. D'autre part, pendant que les exécutants effectuent la mise en place et le blocage du premier crochet, ou du second, etc., un certain nombre de planches restent absolument libres et peuvent facilement glisser, tandis que lorsque les exécutants sont occupés à la fixation de l'une des extrémités du platelage, l'autre extrémité de celui-ci étant libre, l'ensemble du platelage peut basculer autour du bras-porteur sur lequel ils travaillent.One of these drawbacks stems from the fact that they are made up of a fairly large number of parts, which favors the risk of loss on construction sites. They are also relatively expensive. Another drawback of these devices lies in the fact that their installation requires the intervention of at least two performers and is carried out under very precarious security conditions. Indeed, it is essential that one of the performers stands below the deck to position and successively hold the hooks, while a second performer on the deck proceeds to screw the screws into the nuts of said hooks. On the other hand, while the performers carry out the positioning and locking of the first hook, or of the second hook, etc., a certain number of boards remain absolutely free and can easily slide, while when the performers are occupied with the fixing one of the ends of the decking, the other end of the latter being free, the entire decking can tilt around the support arm on which they are working.
La présente invention a pour but de supprimer ces inconvénients.The present invention aims to eliminate these drawbacks.
Selon l'invention, cet objectif est atteint au moyen d'une console métallique comportant un élément porteur exécuté de manière connue en soi et comprenant un bras-support destiné à supporter les planches constituant le platelage de l' échafaudage, et une bride de serrage servant à coincer lesdites planches entre ladite bride et ledit bras-support, cette console métallique étant remarquable par le fait que la bride est formée d'une barre de serrage solidaire d'une pluralité de tiges filetées espacées et orientées perpendiculairement à ladite barre à laquelle elles sont rigidement rattachées par l'intermédiaire de l'une de leurs extrémités, en ce que le bras-support est pourvu de trous et en ce que l'espacement de ces tiges filetées est identique à celui desdits trous, de sorte qu'elles peuvent être engagées dans ces derniers, au travers des interstices réservés entre les planches du platelage, et recevoir un écrou dont le serrage permet de coincer fortement lesdites planches entre ladite barre de serrage et ledit bras-support.According to the invention, this objective is achieved by means of a metal console comprising a carrying element executed in a manner known per se and comprising a support arm intended to support the boards constituting the decking of the scaffolding, and a clamping flange serving to wedge said boards between said flange and said support arm, this metal console being remarkable in that the flange is formed by a clamping bar secured to a plurality of threaded rods spaced apart and oriented perpendicular to said bar to which they are rigidly attached via one of their ends, in that the support arm is provided with holes and in that the spacing of these threaded rods is identical to that of said holes, so that they can be engaged in these, through the interstices reserved between the decking boards, and receive a nut whose tightening allows to wedge strongly said boards between said clamping bar and said support arm.
Grâce à cette console, les planches du platelage peuvent être immobilisées fermement en position, de façon commode et rapide, sans qu'il soit nécessaire de percer, préalablement, des trous dans lesdites planches.Thanks to this console, the decking boards can be immobilized firmly in position, convenient and quick, without the need to drill holes in said boards beforehand.
En outre, le dispositif selon l'invention est constitué d'un nombre réduit de pièces. Son coût est peu élevé et sa mise en oeuvre économique car elle peut s'opérer rapidement par un seul exécutant qui pose d'abord les deux brides de serrage, puis passe ensuite au-dessous de la passerelle pour visser et serrer les écrous. Dès qu'une bride de serrage a été positionnée, les planches ne peuvent plus s'écarter et le platelage ne peut plus basculer autour du bras-support de la console. L'installation du dispositif selon l'invention peut donc s'opérer dans de meilleures conditions de sécurité.In addition, the device according to the invention consists of a reduced number of parts. Its cost is low and its implementation economical because it can be carried out quickly by a single operator who first installs the two clamps, then passes below the gangway to screw and tighten the nuts. As soon as a clamp has been positioned, the planks can no longer move apart and the decking can no longer tilt around the console support arm. The installation of the device according to the invention can therefore take place under better security conditions.

On se reporte auxdits dessins pour décrire un exemple de réalisation avantageux, bien que nullement limitatif, de la console métallique selon l'invention et d'une passerelle de bétonnage exécutée au moyen de celle-ci.Reference is made to said drawings to describe an advantageous, although in no way limiting, embodiment of the metal console according to the invention and of a concrete walkway executed by means of the latter.
La console métallique suivant l'invention comporte un élément porteur 1 réalisé de manière connue en soi et comprenant essentiellement un bras-support 1a et une contrefiche 1b assemblés par une entretoise 1c et dont les extrémités libres sont munies de moyens de fixation 1d, 1e (sabots d'accrochage, etc.), respectivement. Cet élément porteur comporte également un montant 1f agencé pour recevoir les planches destinées à constituer le garde-corps d'une passerelle de bétonnage.The metal console according to the invention comprises a
Le bras-support 1a est pourvu de trous transversaux 1g le traversant dans le sens de son épaisseur ou hauteur.The support arm 1a is provided with
L'élément porteur ainsi exécuté correspond sensiblement à une console métallique traditionnelle.The carrier element thus executed corresponds substantially to a traditional metal console.
Selon l'invention, la console comporte encore une bride 2 comprenant une barre de serrage 2a constituée par un robuste fer plat, et une pluralité de tiges filetées 2b rigidement rattachées à ladite barre, par l'une de leurs extrémités. Ces tiges filetées sont espacées et orientées perpendiculairement à la barre 2a. Leur longueur L est supérieure à la hauteur ou épaisseur l de l'ensemble constitué par le bras-support 1a et les planches P reposant sur celui-ci.According to the invention, the console also comprises a
L'espacement des tiges filetées 2b est identique à celui des trous 1g dans lesquels peuvent être engagées lesdites tiges dont les extrémités filetées sont destinées à recevoir un écrou de serrage 3.The spacing of the threaded
Les écrous de serrage 3 peuvent être d'un type dont la manoeuvre nécessite l'emploi d'une clé spéciale (écrous hexagonaux, par exemple) ou d'un genre manoeuvrable à la main (écrous à oreilles, ou à croisillon, ou à manette de blocage, par exemple).The tightening
Le nombre de trous 1g et le nombre de tiges 2b peut varier en fonction de la longueur du bras-support 1a des éléments porteurs 1 et de la largeur du platelage et de celle des planches destinées à constituer celui-ci.The number of
La barre de serrage 2a a une largeur correspondant sensiblement à celle du bras-support 1a de l'élément porteur 1. Elle peut être un peu plus étroite que celui-ci (figure 3) afin d'augmenter les forces de coincement s'appliquant sur les planches P du platelage.The clamping bar 2a has a width corresponding substantially to that of the support arm 1a of the
D'autre part, la barre de serrage 2a a une longueur correspondant approximativement à celle du bras-support 1a et, de préférence, une longueur inférieure à celle de celui-ci.On the other hand, the clamping bar 2a has a length corresponding approximately to that of the support arm 1a and, preferably, a length less than that of the latter.
On comprend que pour monter une passerelle de bétonnage au moyen des consoles selon l'invention (figure 5), il suffit de poser les extrémités des planches P sur le bras-support 1a de deux éléments porteurs 1 convenablement espacés, en ménageant un faible écartement entre lesdites planches et de placer les barres de serrage 2a des brides 2 contre la face supérieure de ces dernières, après avoir enfoncé les tiges filetées 2b à travers les trous 1g dudit bras-support, lesdites tiges traversant les interstices i réservés entre les planches.It is understood that to mount a concrete walkway by means of the brackets according to the invention (FIG. 5), it suffices to place the ends of the boards P on the support arm 1a of two
Le blocage énergique des planches P sur les bras-supports 1a des éléments porteurs 1, est obtenu au moyen des écrous 3 montés sur les extrémités filetées émergeantes des tiges 2b et dont le serrage a pour effet de rapprocher les barres de serrage 2a desdits bras-supports et de coincer fermement l'extrémité desdites planches entre la face supérieure de ces derniers et la face inférieure desdites barres de serrage (figure 2).The energetic locking of the boards P on the support arms 1a of the
On conçoit que ce montage peut s'effectuer commodément et rapidement, sans aucun outillage ou avec une simple clé.We understand that this assembly can be done conveniently and quickly, without any tools or with a simple key.
Le démontage des passerelles de bétonnage ou autres échafaudages légers réalisés à l'aide des consoles selon l'invention s'opère tout aussi facilement et rapidement.The dismantling of the concrete walkways or other light scaffolding carried out using the brackets according to the invention takes place just as easily and quickly.
