IMPROVEMENTS IN FORMWORK CONSTRUCTION

摘要

A prop (10) for supporting formwork (210, 220) for use in forming a concrete slab comprises a base plate (12) including means (28) for anchoring the base plate to ground using ground engaging means (29). A face plate (14) is hinged to the base plate. The face plate (14) defines a means for attaching a board to the side plate, typically in the form of an array of slots (36). An adjustable prop arm (18) extends between the base plate (12) and the face plate (14) for fixing and maintaining the orientation of the face plate relative to the base plate. The prop includes means (30, 32, 34) for controlled adjustment of the position of the base plate relative to the ground engaging means. Typically, the prop (10) will be made of steel, although other suitable metals or materials could be used. The means for anchoring the base plate to ground may comprise one or more star shaped apertures (28) formed in the base plate -sections having three points and the ground engaging means may comprise star pickets (29).
