  • Method for manufacturing an improved prestressed concrete joist
    Patent number: 6036906
    Abstract: A precast, prestressed concrete joist having web openings through which mechanical and electrical equipment may pass. In an exemplary embodiment, the joist comprises generally horizontal opposite top and bottom concrete members with a concrete web interposed between them. This web may have openings through which mechanical and electrical equipment may pass. Prestress steel strands may extend lengthwise through both the top and bottom members to provide prestress in the concrete joist. The concrete joist may further comprise strand restraining devices for deflecting the prestress steel strands. The precast, prestressed concrete joist having a web opening may be constructed using a reusable casting apparatus. This casting apparatus comprises a prestressing bed onto which a frame may be mounted. The frame provides a means of applying tension to the prestress steel strands and of supporting prestress strand restraining devices.
