Abstract
Description
La présente invention concerne des supports de planches d'échafaudage, ainsi que des échafaudages réalisés avec ces supports. The present invention relates to scaffold plank supports, as well as scaffolding produced with these supports.
Les supports de planche d'échafaudage actuellement connus sont du type chevalet, avec une partie verticale plus ou moins haute au-dessus des pieds. Il en résulte que les bouts des planches ne peuvent être utilisées car dès que ltouvrier s'y trouve, la planche, non tenue à l'autre extrémité, bascule. On peut prévoir des systèmes de serrage des planches sur les bords d'appui des chevalets, mais cela complique le support et le rend onéreux. The currently known scaffolding board supports are of the easel type, with a vertical part which is more or less high above the feet. As a result, the ends of the boards cannot be used because as soon as the worker is there, the board, not held at the other end, tips over. Plank clamping systems can be provided on the support edges of the easels, but this complicates the support and makes it expensive.
Un objet de la présente invention consiste à prévoir des supports de planches d'échafaudage qui évitent les inconvénients mentionnés ci-dessus et soient d'une utilisation extremement simple. An object of the present invention is to provide supports for scaffolding planks which avoid the drawbacks mentioned above and which are extremely simple to use.
Suivant une caractéristique de l'invention, un support de planche d'échafaudage se compose de deux pieds coudés dont la partie inférieure est oblique et la partie supérieure horizontale, les extrémités des parties horizontales des pieds étant réunies par deux traverses dont la différence de hauteur est de l'ordre de l'épaisséur d'une planche. According to a characteristic of the invention, a scaffolding plank support consists of two bent feet, the lower part of which is oblique and the upper part horizontal, the ends of the horizontal parts of the feet being joined by two crosspieces, the difference in height is about the thickness of a board.
Suivant une autre caractéristique, la traverse située près des bouts libres desdites parties horizontales est plus haute que la traverse située à proximité des coudes. According to another characteristic, the cross member located near the free ends of said horizontal parts is higher than the cross member located near the elbows.
Suivant une autre caractéristique, les parties respectivement horizontales et obliques des pieds sont parallèles. According to another characteristic, the respectively horizontal and oblique parts of the feet are parallel.
Suivant une autre caractéristique, lesdites parties obliques sont télescopiques. According to another characteristic, said oblique parts are telescopic.
Suivant une autre caractéristique, il est prévu un échafaudage comprenant une planche et deux tels supports, dont les parties obliques sont orientées en sens inverse. According to another characteristic, there is provided a scaffolding comprising a board and two such supports, the oblique parts of which are oriented in opposite directions.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue en perspective d'un échafaudage formé d'une planche et de deux supports suivant l'invention,
la Fig. 2 est une vue de côté de l'échafaudage de la Fig. 1, et
la Fig. 3 est une- vue en perspective d'un dispositif de l'échafaudage de la Fig. 1. The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a perspective view of a scaffolding formed by a board and two supports according to the invention,
Fig. 2 is a side view of the scaffolding of FIG. 1, and
Fig. 3 is a perspective view of a device of the scaffolding of FIG. 1.
L'échafaudage montré à la Fig. 1 comprend deux supports identiques 1 et 2, orientés dans des sens opposés, et une planche 3 reposant sur les supports 1 et 2. The scaffolding shown in Fig. 1 comprises two identical supports 1 and 2, oriented in opposite directions, and a board 3 resting on the supports 1 and 2.
Le support 1 de la Fig. 2 est constitué de deux pieds coudés, identiques et parallèles 4 et 5 dont une partie 6 est sensiblement horizontale et l'autre partie 7 est orientée de bas en haut avec une certaine obliquité de l'ordre de 1200 par rapport à l'horizontale. The support 1 of FIG. 2 consists of two bent feet, identical and parallel 4 and 5, one part 6 is substantially horizontal and the other part 7 is oriented from bottom to top with a certain obliquity of the order of 1200 relative to the horizontal.
Entre ces deux pieds 4 et 5, aux extrémités libres des parties horizontales 6, sur le dessus, est fixée une traverse métallique 8 dont au moins la face inférieure est plate. Une autre traverse métallique 9 est fixée entre les autres extrémités des parties horizontales 6, mais en dessous. En pratique, quand le coude des pieds est peu prononcé, on peut considérer que la -traverse 9 relie les extrémités supérieures des parties obliques 7 des pieds, ou encore des goussets 10 renforçant les coudes des pieds 4 et 5.Between these two feet 4 and 5, at the free ends of the horizontal parts 6, on the top, is fixed a metal crosspiece 8 of which at least the lower face is flat. Another metal crosspiece 9 is fixed between the other ends of the horizontal parts 6, but below. In practice, when the elbow of the feet is not very pronounced, it can be considered that the cross-member 9 connects the upper ends of the oblique parts 7 of the feet, or else gussets 10 reinforcing the elbows of the feet 4 and 5.
La différence de niveau entre la face inférieure de la traverse 8 et la face supérieure de la traverse 9 est de l'ordre de l'épaisseur de la planche 3. The difference in level between the lower face of the cross member 8 and the upper face of the cross member 9 is of the order of the thickness of the board 3.
Il apparaît, notamment à la Fig. 2, que quand une charge repose sur la planche 3 entre les supports 1 et 2, les traverses 9 supportent le poids, les extrémités supérieures des parties 7 ont tendance à se rapprocher, ce qui provoque le pincement de la planche par les traverses 8, si bien que la planche est parfaitement coincée. It appears, in particular in FIG. 2, that when a load rests on the board 3 between the supports 1 and 2, the crosspieces 9 support the weight, the upper ends of the parts 7 tend to approach each other, which causes the board to be pinched by the crosspieces 8, so that the board is perfectly stuck.
Si la charge repose au-delà d'une traverse 9, étant donné que les extrémités inférieures des pieds sont pratiquement à l'aplomb des extrémités de la planche, il ne se produit aucun couple de renversement. En d'autres mots, la planche ne bascule pas-.If the load rests beyond a cross member 9, since the lower ends of the feet are practically perpendicular to the ends of the board, there is no overturning torque. In other words, the board does not tip over.
Le montage de l'échafaudage est évident. Il suffit de dresser les supports 1 et 2 en face l'un de l'autre et de glisser la planche entre leurs traverses 8 et 9, respectivement. On peut ensuite faire coulisser les supports sur la planche pour leur donner leur écartement définitif. Il apparaît que l'échafaudage est notamment très utile à l'intérieur des immeubles. Pour plus de commodité, les pieds 4 et 5 sont munis d'embases 11 télescopiques, le réglage en hauteur des embases étant résolu classiquement par des trous I2 et des chevilles 13. The assembly of the scaffolding is obvious. It suffices to draw the supports 1 and 2 facing each other and to slide the board between their crosspieces 8 and 9, respectively. We can then slide the supports on the board to give them their final spacing. It appears that scaffolding is particularly useful inside buildings. For convenience, the feet 4 and 5 are provided with telescopic bases 11, the height adjustment of the bases being conventionally resolved by holes I2 and dowels 13.
Dans la description qui précède on a indiqué que les pieds coudés 4 et 5 étaient parallèles, mais il faut bien comprendre qu'ils peuvent n'être pas partiellement ou entièrement dans des plans verticaux parallèles et, notamment, avoir leurs extrémités inférieures plus écartées que leurs extrémités supérieures. In the foregoing description, it has been indicated that the bent feet 4 and 5 were parallel, but it should be understood that they may not be partially or entirely in parallel vertical planes and, in particular, have their lower ends more apart than their upper ends.
Dans les cas aù une extrémité de la planche peut être supportée par une surface plane, telle qu'une marche d'escalier, un seul support suffit à l'autre extrémité. In cases where one end of the board can be supported by a flat surface, such as a stair step, a single support is sufficient at the other end.
Dans les cas où la planche est très longue ou que le poids à supporter est important l'association de plusieurs paires de supports est réalisable. In cases where the board is very long or the weight to be supported is significant, the association of several pairs of supports is possible.
