Document Type and Number:
WIPO Patent Application WO/2003/046311
Kind Code:
A1
Abstract:
A concrete placing form (30), made of a plastic material, having a hollow sheathing plate portion (32) of which one side is a concrete placing surface (31) and hollow side plate portions (33) that bend at right angle at both side edges of the sheathing plate portion (32) in a direction opposite to the concrete placing surface (31) of the sheathing plate portion (32). Rib portions (40) extending in a vertical direction are provided projectingly on the outer surface (38) of each side plate portion (33). One side face of one of the rib portions (40) is on the same plane as the concrete placing surface (31) of the sheathing plate portion (32). Cutout grooves (41) are formed in the rib portions (40) at the same position such that the grooves are perpendicular to the length direction of the rib portions (40). Metal members for forms, which members have been used for conventional plywood forms in making a form (installation), can be used for the form (30). The form (30) is light−weighted, is excellent in constructibility, is highly durable, hardly causes concrete leakage, and is recyclable.
