SUSPENSION BRIDGE FRAME, SUSPENSION BRIDGE, AND SUSPENSION BRIDGE ERECTION METHOD

摘要

To provide a suspension bridge frame, in which upper left and right parts and lower left and right parts are held by cables, and a suspension bridge using the suspension bridge frame with high stability; and to provide a suspension bridge erection method, a suspension bridge, and a suspension bridge frame used by these, constructed, at a low cost, by sequentially connecting suspension bridge frames on the shore side and sending them to the opposite shore side, and which excels in safety during erection.SOLUTION: In a suspension bridge frame 30 and a suspension bridge 80, main cables 50a, 50b are respectively fixed and held at the upper left, upper right, lower left, and lower right of the suspension bridge frame 30 such that the stability can be improved. In the suspension bridge erection method, temporary suspension of the suspension bridge frame 30 to the main cables 50a, 50b and connection by a connection member are performed on the shore side on the ground, and this is sent to the opposite shore side for erection. As a result, work at a high place is reduced and safety is improved, work efficiency is improved, and the cost can be reduced by shortening the construction period and reducing labor costs.SELECTED DRAWING: Figure 7
