Description

L'invention concerne généralement un dispositif de montage d'un élément de plancher monobloc sur un échafaudage, ainsi qu'un élément de plancher pourvu de ce dispositif de montage.The invention generally relates to a device for mounting a one-piece floor element on a scaffold, as well as a floor element provided with this mounting device.

On connaît déjà plusieurs types de dispositifs de montage d'un élément de plancher monobloc ou d'un plancher composite, sur un échafaudage. Dans la technique antérieure, les planchers, quand ils sont formés de plusieurs planches placées côte à côte, sont maintenus dans la position voulue sur l'échafaudage en étant coincés à leurs extrémités entre deux éléments transversaux horizontaux portés par un cadre d'échafaudage.Several types of devices are already known for mounting a one-piece floor element or a composite floor on a scaffold. In the prior art, the floors, when they are formed from several boards placed side by side, are held in the desired position on the scaffolding by being wedged at their ends between two horizontal transverse elements carried by a scaffolding frame.

Pour améliorer la solidité et faciliter la manipulation et le montage des planchers, on a récemment proposé de remplacer ces planchers formés par des planches disposées côte à côte, par des éléments de plancher monoblocs, qui sont beaucoup plus résistants et beaucoup plus légers que des planches de bois, et qui forment chacun une section complète de plancher ayant la largeur et la longueur voulues. Dans la technique connue, ces éléments monoblocs sont généralement pourvus à leurs extrémités de crochets comprenant une partie droite par laquelle ces crochets sont fixés sur l'élément de plancher et une partie en arc de cercle que l'on vient appuyer sur une traverse horizontale d'un cadre d'échafaudage. Les éléments de plancher sont ainsi simplement accrochés sur les cadres d'échafaudage; en d'autres termes, ils sont simplement appuyés à leurs extrémités sur des traverses horizontales des cadres d'échafaudage.To improve the solidity and facilitate the handling and the assembly of the floors, it has recently been proposed to replace these floors formed by boards placed side by side, by monoblock floor elements, which are much stronger and much lighter than boards. of wood, and which each form a complete section of floor having the desired width and length. In the known technique, these monoblock elements are generally provided at their ends with hooks compre nant a straight part by which these hooks are fixed on the floor element and a part in an arc which is just supported on a horizontal crosspiece of a scaffolding frame. The floor elements are thus simply hung on the scaffolding frames; in other words, they are simply supported at their ends on horizontal crosspieces of the scaffolding frames.

La présente invention a pour but d'améliorer la sécurité des ouvriers travaillant sur un échafaudage, en améliorant pour cela le montage des éléments de plancher sur les cadres d'échafaudage.The present invention aims to improve the safety of workers working on scaffolding, by improving the mounting of the floor elements on the scaffolding frames.

L'invention propose donc un dispositif de montage, sur un échafaudage, d'un élément de plancher monobloc formant une section complète de plancher s'étendant entre deux cadres latéraux verticaux d'échafaudage, en étant fixé à ses extrémités au moyen de pattes d'accrochage sur des traverses horizontales desdits cadres, caractérisé en ce que lesdites pattes solidaires des extrémités de l'élément de plancher comprennent des moyens coopérant avec les traverses horizontales des cadres pour former un semi-encastrement rigide de l'élément de plancher sur les traverses, l'ensemble formant contreventement horizontal.The invention therefore provides a device for mounting, on a scaffold, a monobloc floor element forming a complete section of floor extending between two vertical side scaffolding frames, being fixed at its ends by means of lugs 'hooking on horizontal sleepers of said frames, characterized in that said tabs integral with the ends of the floor element comprise means cooperating with the horizontal sleepers of the frames to form a rigid semi-embedding of the floor element on the sleepers , the assembly forming horizontal bracing.

Ainsi, selon l'invention, les éléments de plancher ne sont plus simplement posés ou appuyés à leurs extrémités sur des traverses horizontales, ils sont pratiquement encastrés sur ces traverses. La rigidité du montage est grandement améliorée, ainsi que la fiabilité de la fixation de l'élément de plancher.Thus, according to the invention, the floor elements are no longer simply placed or supported at their ends on horizontal crosspieces, they are practically embedded on these crosspieces. The rigidity of the mounting is greatly improved, as well as the reliability of the fixing of the floor element.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre, faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :

  • la figure 1 est une vue schématique de dessus de plusieurs éléments de plancher montés au moyen d'un dispositif selon l'invention sur des traverses horizontales de cadre d'échafaudage ; la figure 2 est une vue agrandie en coupe selon la ligne II-II de la figure 1 ; et la figure 3 est une vue de dessus d'une patte d'accrochage selon l'invention.
The invention will be better understood, and other aims, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating an embodiment of the invention and in which:
  • Figure 1 is a schematic top view of several floor elements mounted by means of a device according to the invention on horizontal crosspieces of scaffolding frame; Figure 2 is an enlarged sectional view along line II-II of Figure 1; and Figure 3 is a top view of a fastening tab according to the invention.

On a donc représenté schématiquement en figure 1 des éléments de plancher 10 selon l'invention, fixés sur des traverses horizontales 11 de deux cadres latéraux d'échafaudage. L'élément de plancher 10 représenté à gauche en figure 1 a été dessiné écarté de la traverse horizontale correspondante 11, tandis que l'élément de droite est représenté monté sur la traverse correspondante 11, tout comme l'élément central 10.There is therefore shown diagrammatically in FIG. 1 floor elements 10 according to the invention, fixed to horizontal crosspieces 11 of two lateral scaffolding frames. The floor element 10 represented on the left in FIG. 1 has been drawn apart from the corresponding horizontal cross member 11, while the right element is shown mounted on the corresponding cross member 11, just like the central element 10.

Chaque élément de plancher 10 est un élément monobloc, formant une section complète de plancher entre deux traverses horizontales 11 de cadre d'échafaudage. Cet élément de plancher peut être réalisé de diverses façons connues, et il a pour caractéristique d'être beaucoup plus résistant et beaucoup plus léger qu'un plancher correspondant formé de planches en bois, et d'être également plus résistant aux intempéries.Each floor element 10 is a one-piece element, forming a complete section of floor between two horizontal crosspieces 11 of the scaffolding frame. This floor element can be made in various known ways, and it has the characteristic of being much more resistant and much lighter than a corresponding floor formed of wooden planks, and also being more resistant to weathering.

Chaque élément de plancher 10 comprend quatre pattes d'accrochage 12 qui sont prévues sensiblement à ses quatre coins, de la façon indiquée ci-dessous.Each floor element 10 has four legs attachment 12 which are provided substantially at its four corners, as shown below.

Chaque patte d'accrochage 12, comme on le voit mieux dans les figures 2 et 3, a en section transversale ou en vue de côté, sensiblement la forme d'un S dont une première extrémité 13 est fixée sur la face inférieure 14 de l'élément de plancher 10, tandis que la seconde extrémité 15 de la patte 12 s'étend parallèlement à la première extrémité 13, et sensiblement en prolongement de la face supérieure 16 de l'élément de plancher 10, dans la direction longitudinale de celui- ci. Les deux parties d'extrémité 13 et 15 sont réunies entre elles par une partie droite 17 perpendiculaire aux deux parties d'extrémité 13 et 15.Each lug 12, as best seen in Figures 2 and 3, has in cross section or in side view, substantially the shape of an S, a first end 13 is fixed on the underside 14 of the 'floor element 10, while the second end 15 of the lug 12 extends parallel to the first end 13, and substantially in extension of the upper face 16 of the floor element 10, in the longitudinal direction thereof this. The two end parts 13 and 15 are joined together by a straight part 17 perpendicular to the two end parts 13 and 15.

Comme on le voit en figures 1 et 3, la partie d'extrémité 15 est à peu près deux fois moins large que la partie d'extrémité 13.As can be seen in FIGS. 1 and 3, the end part 15 is approximately half as wide as the end part 13.

Cette partie d'extrémité 15 comprend un téton cylindrique rigide 18, dont une extrémité est engagée dans un trou de la partie 15 de la patte 12, et est solidaire de cette partie 15 par exemple par soudure, le téton cylindrique 18 s'étendant vers le bas perpendiculairement aux parties d'extrémité 13 et 15 de la patte 12, sur une longueur qui est sensiblement égale à l'épaisseur de l'élément de plancher 10 et qui est de toute façon supérieure au diamètre extérieur de la traverse cylindrique 11 sur laquelle l'élément de plancher 10 est destiné à être monté.This end portion 15 comprises a rigid cylindrical stud 18, one end of which is engaged in a hole in the portion 15 of the tab 12, and is secured to this portion 15 for example by welding, the cylindrical stud 18 extending towards the bottom perpendicular to the end portions 13 and 15 of the tab 12, over a length which is substantially equal to the thickness of the floor element 10 and which is in any case greater than the outside diameter of the cylindrical cross member 11 on which the floor element 10 is intended to be mounted.

Comme indiqué plus haut, chaque patte 12 est fixée, par sa partie d'extrémité 13, sur la face inférieure 14 de l'élément de plancher 10. Pour cela, la partie 13 comprend deux trous 19 correspondant à des trous sensiblement de même diamètre 20 qui sont formés dans l'épaisseur de l'élément de plancher 10 et qui sont destinés à recevoir des tubes cylindriques 21 de fixation, dont les extrémités supérieures et inférieures sont serties, respectivement sur la face inférieure de la partie 13 de la patte 12 et sur une plaquette métallique 22 interposée entre la surface supérieure 16 de l'élément de plancher 10 et l'extrémité supérieure des tubes 21.As indicated above, each tab 12 is fixed, by its end part 13, to the underside 14 of the floor element 10. For this, the part 13 comprises two holes 19 corresponding to holes substantially of the same diameter 20 which are formed in the thickness of the floor element 10 and which are intended to receive cylindrical fixing tubes 21, the upper and lower ends of which are crimped, respectively on the underside of the part 13 of the tab 12 and on a metal plate 22 interposed between the upper surface 16 of the floor element 10 and the upper end of the tubes 21.

On notera encore que chaque patte d'accrochage 12 comporte des nervures de renforcement 23 comme représenté dans les figures 2 et 3.It will also be noted that each attachment tab 12 has reinforcing ribs 23 as shown in FIGS. 2 and 3.

Les pattes d'accrochage 12 sont montées sur un élément de plancher 10 avec la disposition suivante : chaque côté transversal d'extrémité 24 d'un élément de plancher 10 comprend deux pattes d'accrochage 12 qui sont disposées, sur ce côté 24, de la même façon, comme représenté en figure 1. Les pattes d'accrochage 12 prévues sur l'autre côté transversal d'extrémité 24 de l'élément 10 sont en position inverse, comme représenté en figure 1. En d'autres termes, les tétons 18 des deux pattes 12 d'un même côté transversal 24 sont décalés latéralement dans le même sens par rapport à l'axe longitudinal médian de l'élément 10, tandis que les tétons 18 des pattes d'accrochage 12 prévus sur l'autre bord transversal 24 sont décalés dans le sens opposé par rapport à cet axe longitudinal médian. On pourrait également dire que les pattes d'accrochage 12 d'un élément de plancher 10 sont disposées deux à deux symétriquement par rapport au point central médian de l'élément 10, constitué par le point de croisement des diagonales de cet élément de plancher.The latching lugs 12 are mounted on a floor element 10 with the following arrangement: each transverse end side 24 of a floor element 10 comprises two latching lugs 12 which are arranged, on this side 24, of the same way, as shown in Figure 1. The lugs 12 provided on the other transverse end side 24 of the element 10 are in reverse position, as shown in Figure 1. In other words, the nipples 18 of the two legs 12 on the same transverse side 24 are offset laterally in the same direction relative to the median longitudinal axis of the element 10, while the nipples 18 of the hooking lugs 12 provided on the other transverse edge 24 are offset in the opposite direction with respect to this median longitudinal axis. One could also say that the hooking lugs 12 of a floor element 10 are arranged two by two symmetrically with respect to the central midpoint of the element 10, constituted by the point of intersection of the diagonals of this floor element.

Comme représenté en figure 1, cette disposition permet de disposer les éléments de plancher 10 pratiquement bout à bout, au même niveau, sans pratiquement aucune discontinuité de surface entre deux éléments consécutifs.As shown in Figure 1, this arrangement allows to have the floor elements 10 practically end to end, at the same level, with practically no surface discontinuity between two consecutive elements.

Pour le montage des éléments de plancher 10, chaque traverse horizontale 11 comprend quatre trous verticaux diamétraux 25 destinés à recevoir chacun un téton cylindrique 18, comme représenté dans les figures 1 et 2.For mounting the floor elements 10, each horizontal cross member 11 comprises four vertical diametrical holes 25 intended to each receive a cylindrical stud 18, as shown in FIGS. 1 and 2.

Le montage des éléments de plancher selon l'invention se fait donc de façon extrêmement simple : il suffit de prendre un élément de plancher 10 et de l'amener au-dessus de ces deux traverses horizontales 11 de montage, puis d'introduire les tétons 18 des quatre pattes 12 prévues sensiblement aux quatre coins de l'élément 10 dans les trous correspondants 25 des deux traverses horizontales 11. Comme les tétons 18 ont une longueur supérieure au diamètre extérieur des traverses horizontales 11, chaque téton 18 fait légèrement saillie à sa partie inférieure à l'extérieur de la traverse 11. Cette disposition permet de réaliser un semi-encastrement rigide de l'élément de plancher 10 à ses extrémités sur les traverses horizontales 11.The assembly of the floor elements according to the invention is therefore extremely simple: it suffices to take a floor element 10 and bring it above these two horizontal crossmembers 11 for mounting, then to introduce the pins 18 of the four legs 12 provided substantially at the four corners of the element 10 in the corresponding holes 25 of the two horizontal crosspieces 11. As the studs 18 have a length greater than the outside diameter of the horizontal crosspieces 11, each stud 18 protrudes slightly at its lower part outside the cross member 11. This arrangement makes it possible to produce a rigid semi-embedding of the floor element 10 at its ends on the horizontal cross members 11.

On notera encore, en figure 2 que la distance entre l'axe d'un téton 18 d'une patte 12 et la surface des nervures 23 correspondante est sensiblement égale ou très légèrement supérieure au rayon extérieur d'une traverse 11. Ainsi, quand le téton 18 est introduit dans un trou 25 de la traverse 11, cette traverse 25 est bloquée entre le téton et les nervures 23 correspondantes de la patte 12.It will also be noted, in FIG. 2, that the distance between the axis of a stud 18 of a lug 12 and the surface of the corresponding ribs 23 is substantially equal or very slightly greater than the outside radius of a cross member 11. Thus, when the stud 18 is introduced into a hole 25 in the cross member 11, this cross member 25 is blocked between the stud and the corresponding ribs 23 of the tab 12.

On remarquera également qu'il n'est pas nécessaire de présenter un élément de plancher 10 dans une orientation particulière pour pouvoir le monter sur les traverses 11 correspondantes. En effet, si l'élément 10 est tourné de 180° par rapport à la position représentée en figure 1, il se monte exactement de la même façon sur les traverses 11.Note also that there is no need to present a floor element 10 in a particular orientation to be able to mount it on the corresponding crosspieces 11. Indeed, if the element 10 is rotated 180 ° relative to the position shown in FIG. 1, it is mounted in exactly the same way on the crosspieces 11.

On remarquera également que l'élément de plancher, une fois monté en place, forme un contreventement horizontal de l'échafaudage.It will also be noted that the floor element, once mounted in place, forms a horizontal bracing of the scaffolding.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et représenté qui n'a été donné qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits ainsi que leurs combinaisons, si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent.Of course, the invention is in no way limited to the embodiment described and shown which has been given only by way of example. In particular, it includes all the means constituting technical equivalents of the means described as well as their combinations, if these are carried out according to the spirit and implemented in the context of the claims which follow.
