Device for supporting formwork boards on beam for building concrete structure, has screw or cam supported on holding branch to exert thrust on part of locking element such that return portions enclose under-surfaces of upper wing of beam

摘要

The device (1) has a support fitting (2) whose support branch (3) receives a formwork board and holding branch (4) rests on an upper wing (5) of a beam (6). A locking element (12) has a quadrangular cross-sectional part (13) with a rear wall (14) and a longitudinal slot (15) bordered by return portions (16). The element part is engaged on the beam such that the holding branch is inserted between the wall and the beam. A screw or cam (17) of the element is supported on the holding branch to exert a thrust on the element part such that the return portions enclose under-surfaces (8) of the wing.
