发明名称 CONCRETE MOLDING FORM MEMBER CONNECTOR
摘要 A concrete molding form member connector comprises a first holding portion having a linearly extending first holding surface of a prescribed length, a cylindrical insertional shaft portion, having a central axis being perpendicular to the first holding surface, which is provided in the vicinity of a first end of the first holding surface, and a second holding portion, having a second holding surface being opposed to the first holding surface in a parallel manner at a prescribed space in a region close to a second end of the first holding surface, which is continuous with the first holding portion on the second end of the first holding surface so that its free end is positioned at a prescribed space with respect to the insertional shaft portion. The insertional shaft portion is inserted in through holes which are provided in overlapping side plate portions of adjacent form members so that the connector is rotated about the same, whereby the side plate portions of the adjacent form members are held between the first holding surface and the second holding surface. Consequently, a lightweight concrete molding form member connector having excellent workability, which can be provided at a relatively low cost, is provided.
