On sait que ces échafaudages sont posés au sol et stabilisés en les fixant à des vérins à vis bloqués dans les embrasures des fenêtres de la façade. Il est donc important que ces vérins exercent sur les surfaces sur We know that these scaffolds are placed on the ground and stabilized by fixing them to screw jacks blocked in the windows of the facade windows. It is therefore important that these cylinders exert on the surfaces on
lesquelles ils sont en appui une force suffisante. which they are supporting sufficient force.
Il est donc d'usage de resserrer périodiquement ces vérins. Toutefois, il importe également que cette force n'atteigne pas une valeur qui risquerait d'endommager le mur sur lequel est monté l'échafaudage. Il existe donc un besoin d'un moyen permettant de connaître en permanence l'effort exercé par It is therefore customary to periodically tighten these jacks. However, it is also important that this force does not reach a value that could damage the wall on which the scaffolding is mounted. There is therefore a need for a means enabling the effort exerted by
ces vérins sur les surfaces sur lesquelles il est en appui. these jacks on the surfaces on which it is supported.

Le dispositif selon l'invention comprend pour l'essentiel un organe tubulaire extérieur 1, un organe tubulaire intérieur de compression 2, et un empilage de rondelles Belleville 3 disposé entre les organes 1 et 2. Les rondelles 3 sont en appui d'une part sur un épaulement 4 de l'organe 1 et d'autre part sur un épaulement 5 de l'organe 2. L'organe 2 peut donc coulisser à l'intérieur de l'organe 1 en comprimant plus ou moins l'empilage de rondelles 3. Un joint torique assure l'étanchéité entre les organes 1 et 2 de The device according to the invention essentially comprises an external tubular member 1, an internal tubular compression member 2, and a stack of Belleville washers 3 disposed between the members 1 and 2. The washers 3 are supported on the one hand on a shoulder 4 of the member 1 and on the other hand on a shoulder 5 of the member 2. The member 2 can therefore slide inside the member 1 by more or less compressing the stack of washers 3. An O-ring seals between organs 1 and 2 of
manière à isoler les rondelles 3.to isolate the washers 3.
Ce coulissement contre l'action des rondelles élastiques 3 s'effectue sous l'action de deux éléments de compression, ici une extrémité 6 d'un vérin de compression et une extrémité 7 d'un tube, dont les autres extrémités sont par exemple en appui sur les deux surfaces latérales d'une embrasure de fenêtre non représentée. L'extrémité 6 du vérin de compression vient en appui sur un épaulement 8 de l'organe 2 et l'extrémité 7 du tube est en appui This sliding against the action of the elastic washers 3 takes place under the action of two compression elements, here one end 6 of a compression cylinder and one end 7 of a tube, the other ends of which are for example in support on the two lateral surfaces of a window embrasure not shown. The end 6 of the compression cylinder comes to bear on a shoulder 8 of the member 2 and the end 7 of the tube is in support
sur un épaulement 9 de l'organe 1.on a shoulder 9 of the member 1.
