APPARATUS FOR PRODUCTION OF CAST CONCRETE MEMBERS

摘要

Prestressed cast concrete structural members which are T-shape or multiple T-shape in cross section are cast in a metal mold. Each T portion of the mold comprises inverted L-shape form members, the depending portions of which have pin members affixed thereto. The pin members are cooperatively received in diagonal slots of a horizontally movable cam plate. Movement of the cam plate causes the depending portions to move laterally away from one another to enable stripping of the cast member from the form. A separately constructed vertically movable horizontal pallet member forms the bottom surface of the form and includes a roller transfer assembly supported on an elevator mechanism. By cam action, the cast member is raised and then transferred to a roller conveyor which engages the bottom surfaces of the extending arms of the cast member. The roller conveyor transfers the member to another work area.
