PURPOSE: A bridge construction method using a tendon and a connecting support is provided to remarkably reduce stress generated in a girder when external force is applied to the girder. CONSTITUTION: A bridge construction method using a tendon and a connecting support is as follows. A form is installed. A sheath, a connecting anchorage, and a connecting support(120) are arranged on specific position inside the form. A concrete member is formed by placing and curing concrete in the form. Anchorages are installed in both ends of the concrete member. A girder(160) is manufactured by inserting a tendon(150) in the sheath and tensing the inserted tendon. Multiple girders are placed on piers and abutments at uniform intervals. Tendons or steel bars are inserted between the connecting anchorages. A slab(190) is formed by placing concrete on the top of the girders. |
