TEMPORARY REINFORCING APPARATUS FOR INCREASING CAST HEIGHT OF CONCRETE IN CONCRETE FILLED TUBE COLUMN

摘要

PURPOSE: A temporary reinforcing support for a concrete filled steel pipe column for increasing the concrete placing height is provided to increase the concrete placing height by suppressing the deformation of a steel pipe when filling concrete by using a thin steel pipe. CONSTITUTION: A temporary reinforcing support for a concrete filled steel pipe column for increasing the concrete placing height is composed of a reinforcement prop, a tendon member(120), and a connection member. The reinforcement prop is longitudinally installed in the outside of a steel pipe(10). The tendon member is spaced at the fixed interval along the longitudinal direction of the reinforcement prop. The connection member is combined in both ends of the tendon member. The connection member applies the tensile force and anchors the tendon member at the closed section. The reinforcement prop is an assembly prop formed by combining the steel plate to the longitudinal direction of the small diameter steel pipe. The tendon member includes a steel wire and a steel strand. The connection member includes a turn buckle(130a).
