Concrete molding form member, and form member space holder and form member connector for assembling the same

摘要

A concrete molding form member comprises a long flat front plate portion (3), a pair of horizontal side plate portions (4, 4) perpendicularly extending from cross-sectional ends of the front plate portion toward its back surface, and a horizontal pair of rear plate portions (5, 5) perpendicularly inwardly extending from forward ends of the side plate portions to be opposed to the back surface of the front plate portion (3), and is integrally formed by a fiber reinforced plastic material. Each of the front plate portion (3), the side plate portions (4, 4) and the rear plate portions (5, 5) is provided with a plurality of mounting holes (6, 7, 8, 13, 14) in the same longitudinal positions at prescribed intervals, so that the distances between centers of the mounting holes which are arranged in the side plate portions and the surface of the front plate portion (3) are set to be substantially equal to those between centers of the mounting holes which are arranged in the rear plate portions and surfaces of the side plate portions. According to this structure, it is possible to provide a concrete molding form member having excellent workability, which comprises advantages of conventional wood, metal and synthetic resin form members and can be provided with both functions of concrete molding surfaces and connecting surfaces not only on its surface but on side surfaces, a back surface and upper and lower surfaces, at a relatively low manufacturing cost.
