STAY-IN-PLACE BEAM FORMWORK FOR CONCRETE STRUCTURES

摘要

A beam formwork (10) comprises an elongated body having a base wall (12) and two side walls (14) extending upwardly from opposite longitudinal edges of the base wall (12). The base wall (12) and the side walls (14) define a channel cavity (16) therebetween having an open top (18) and open ends (20). Seats (24) are formed along top edges of the side walls (14), via the side wall top edges being formed into an L-shape, for receiving edges of decking plates (42) thereon. End flanges (30) extend from ends of the side walls (14), the end flanges (30) being directed outwardly sideways to be perpendicular to the side walls (14). Flange attachment apertures (32) are formed along the end flanges (30). Spaced bracket attachment apertures (34) are formed along lower edges of the side walls (14).
