PURPOSE: A cable-stayed bridge type long-span temporary bridge is provided to extend a span of a temporary bridge which gets various loads or sudden change in load safely and easily with a simple structure by connecting a stay cable to a spot required with tensile force when forming a long span on a temporary bridge. CONSTITUTION: The cable-stayed bridge type long-span temporary bridge contains a pier(1), a main girder(3) installed on the upper side of the pier(1), many lining plates(4) installed on the upper side of the main girder(3), a coupling frame(8) installed on both upper sides of the pier(1) to be interposed between the pier(1) and the main girder(3), a main tower frame(2) whose lower end is attached to the lower part of each coupling frame(8) and upper end is located higher than the upper side of the main girder(3), many cable anchorages(6) located on the structurally preset spot and attached to both sides of the main girder(3), many stay cables(7) connecting an upper end of the main tower frame(2) and the cable anchorages(6), at least one or more crossbeams(5) located on the structurally preset spot and attached to the lower end of the main girder(3), and a connecting slab(9) formed in the L-shape to set both ends of the main girder(3) for connecting a temporary bridge with a road evenly and stably. |
