Abstract

L'invention concerne un outil de chantier, en particulier un rabot servant au traitement de surfaces d'enduit ou de surfaces de support d'enduit. L'invention vise à créer un outil de chantier du type ci-dessus, en particulier un rabot à grille, qui se distingue par une résistance structurale élevée, qui offre par rapport aux conceptions connues jusqu'à présent des avantages en termes de techniques de manipulation, et qui puisse en outre être produit à un coût encore plus avantageux en termes de techniques de fabrication. À cet effet, l'outil de chantier selon l'invention, en particulier un rabot à grille servant à traiter des surfaces d'enduit ou des surfaces de support d'enduit, comporte un corps de base réalisé sous la forme d'une structure en grille et comprenant plusieurs traverses de travail qui forment en tant que telles une zone de bords de travail pénétrant dans une zone de travail. Au moins deux desdites traverses de travail sont réalisées sous la forme de branches longitudinales d'un élément profilé en U ouvert en direction de la zone de travail, et une patte de fixation produite sur chaque élément profilé en U par une découpe de l'élément profilé en U s'élève sur une surface arrière de l'élément profilé en U opposée à la zone de travail au-delà de ladite surface arrière.
