Scaffold module

Abstract

A scaffold module has a floor and two upright side sections, which are hinged to lengthwise edges of the floor. Each hinge is formed by two extrusion pieces that can be pushed into each other, and is made so that the side sections can only be folded towards the floor in a direction towards each other. Each side section is made of one extrusion piece, in which a section of the extrusion piece forms a section of the hinges. The edges of the floor are formed by girders, between which there is a plastic plate. The girders are each formed of one extrusion piece, which forms the other section of the hinges.

1 . A scaffold module comprising:
 a floor plate having opposed longitudinal edges; and   two side sections, each attached to one of the opposed longitudinal edges, each of the side sections comprising:
 a girder extrusion piece having an attachment flange for attaching the girder extrusion piece to the opposed longitudinal edges of the floor plate, the girder extrusion piece further including an inner cylindrical portion surrounded in part by a concentric semi-circular wall, the concentric semi-circular wall being spaced a distance from the inner cylindrical portion; and 
 a wall extrusion piece that includes a middle semi-circular wall that can be slidably engaged with the girder extrusion piece, such that the middle semi-circular wall is positioned between the concentric semi-circular wall and the inner cylindrical portion, to form a hinge that enables the wall extrusion piece to be pivoted with respect to the girder extrusion piece towards the floor plate. 
   
     
     
         2 . The scaffold module of  claim 1 , wherein the wall extrusion piece includes cut-out openings. 
     
     
         3 . A method of manufacturing a scaffold module, the method comprising the steps of:
 providing a floor plate having opposed longitudinal edges;   extruding two girder extrusion pieces, each of the girder extrusion pieces having an inner cylindrical portion surrounded in part by a concentric semi-circular wall, the concentric semi-circular wall being spaced a distance from the inner cylindrical portion;   attaching each of the girder extrusion pieces to one of the opposed longitudinal edges of the floor plate;   extruding two wall extrusion pieces that each include a middle semi-circular wall; and   slidably engaging each of the wall extrusion pieces with one of the girder extrusion pieces, such that the middle semi-circular wall is positioned between the concentric semi-circular wall and the inner cylindrical portion, to form a hinge that enables the wall extrusion piece to be pivoted with respect to the girder extrusion piece towards the floor plate.
