Definitions
- tray made of aluminum and made of wood has a ladder beam made up of crimped beams and bars, supporting the floor in plywood.
- the hooks are usually placed in the extension of the side members.
- the crimping bars on the beams requires qualities aluminum with a very high elongation percentage, therefore low mechanical resistance, to be compensated by a multiplication of the number of bars. Failure to have end crosspieces, in this kind of scaffolding platform, prohibits certain provisions of hooks.
- the invention aims to resolve these various problems, and thus eliminate the disadvantages exposed higher, providing a scaffolding platform of the type made of aluminum and wood which is light and economical manufacturing, while offering resistance high mechanical and small footprint of storage.
- the tubular conformation of the constituent profile of the spar 3 defines an interior space 12.
- the end crosspiece 4 is interrupted along a corresponding vertical plane, substantially, at the median of the triangular section of the spar 3.
- the interior space 12 of the constituent profile this spar 3 is thus made accessible, and allows the introduction of a corner piece 20, in terms of synthetic or other material, clearly visible in the figure 2.
- the corner piece 20 has a body 21, and two tenons 22 and 23 arranged at right angles.
- the first tenon 22 is engaged in a housing 24 at one end of the crosspiece 4.
- the second tenon 23 is engaged in space interior 12 of the profile constituting the beam 3, and more particularly in the part of this interior space 12 delimited by the external inclined flank 8 and by the two superimposed ribs 13 and 14.
- the corner piece 20 is first engaged in the housing 24 of the cross 4, then introduced into the interior space 12 of the beam 3, and it is automatically blocked when the nut 18 is tightened on the thread 17 of the rod 16.

Description
Claims (8)
- Plateau d'échafaudage, du type réalisé en aluminium et en bois, constitué d'un cadre rectangulaire (1) notamment en aluminium et d'un plancher (2) notamment en contreplaqué, s'insérant dans le cadre (1), ce cadre (1) étant lui-même constitué de deux longerons (3) et de deux traverses d'extrémité (4) sous forme de profilés extrudés notamment en aluminium, caractérisé en ce que les profilés constituant les longerons (3) du cadre (1) comportent au moins une rainure longitudinale (11,27) ou un conduit longitudinal recevant une tige en acier continue (16), s'étendant sur toute la longueur du longeron (3) et servant de moyen de renforcement ainsi que de moyen de fixation des traverses d'extrémité (4), ladite tige en acier (16) comportant des extrémités filetées (17), prévues pour traverser de part en part les traverses d'extrémité (4), appliquées contre les extrémités des longerons (3), et pour recevoir des écrous de serrage (18).
- Plateau d'échafaudage selon la revendication 1, caractérisé en ce que les profilés constituant les longerons (3) du cadre (1) possèdent une section transversale sensiblement triangulaire, la pointe de la section triangulaire étant dirigée vers le bas, ces profilés comportant une rainure longitudinale (11) ou un conduit longitudinal situé dans la région de la pointe inférieure de sa section triangulaire, et apte à recevoir la tige en acier (16), tandis que la base (7) de ladite section triangulaire, opposée à sa pointe, forme partiellement la surface du plancher (2) du plateau d'échafaudage.
- Plateau d'échafaudage selon la revendication 1 ou 2, comportant des crochets (5) situés dans le prolongement des longerons (3), caractérisé en ce que les tiges en acier (16), portant à leurs extrémités filetées (17) des écrous (18), assurent aussi la fixation des crochets (5).
- Plateau d'échafaudage selon l'une quelconque des revendications 1 à 3, caractérisé en ce que la longueur des traverses d'extrémité (4) est déterminée de telle façon que les faces d'extrémité de chaque traverse (4), assemblée aux longerons (3), correspondent sensiblement à la médiane verticale de la section de ces longerons (3), et plus particulièrement à la médiane de la section triangulaire desdits longerons (3).
- Plateau d'échafaudage, selon la revendication 4, caractérisé en ce qu'à chaque jonction d'une traverse (4) et d'un longeron (3) est insérée une pièce d'angle (20), engagée d'une part dans la traverse (4) et d'autre part dans le longeron (3), la pièce d'angle (20) obturant l'angle des deux profilés constituant respectivement le longeron (3) et la traverse (4).
- Plateau d'échafaudage selon la revendication 5, caractérisé en ce que le profilé constituant chaque longeron (3) comporte deux nervures longitudinales intérieures (13,14), délimitant une partie de l'espace intérieur (12) de ce profilé dans laquelle est engagé un tenon (23) de la pièce d'angle (20).
- Plateau d'échafaudage selon la revendication 5 ou 6, caractérisé en ce que la pièce d'angle (20) comporte, débouchant sur sa face supérieure, un logement (25) notamment de forme cylindrique, adapté pour la fixation de l'extrémité (26) d'une plinthe (6) longeant ce plateau d'échafaudage.
- Plateau d'échafaudage selon l'une quelconque des revendications 5 à 7, caractérisé en ce que la pièce d'angle (20) présente une forme extérieure arrondie.
