Abstract: A variable pitch corrugated support sheet with accompanying support beam consists in a bearing sheet having a corrugated pattern and by varying the angle, or pitch, of the corrugated pattern of the bearing sheet, its load carrying capacity can be altered. In order to maintain a given angle, a series of accompanying structural beams with specific angles are designed to receive the bearing sheet and give it its angle. With the structural beam imparting an angle to the corrugated pattern of the sheet, that given angle is maintained and a top layer can be applied to the corrugated support sheet such as concrete, foam, plywood or any other such covering suitable for the function of that structure whether a floor, a ceiling or a roof.

Abstract: A mounting bracket for use to install a shelving accessory such as a drawer, a roll frame or a flipper door, into an office shelving unit comprising two opposite pairs of posts forming together a supporting frame structure. The bracket comprises an elongated plate provided at both ends with two U-shaped end portions. One of these end portions is provided with holes, whereas the other end portion is provided with slots which extend over part of the outer wall and part of the bottom wall of the U-shape. These U-shaped portions and the presence of slots in one of them make it possible to install the mounting bracket in a retrofit manner between one of the sets of posts in which bolts are previously inserted at a required height.
