STIFFENING GIRDER OF SUSPENSION BRIDGE, AND METHOD FOR CONSTRUCTING THE SAME

摘要

PROBLEM TO BE SOLVED: To simplify constitution of a stiffening girder of a suspension bridge, and to secure wind-resistant stability both in and after construction.;SOLUTION: This stiffening girder 1 (of the suspension bridge) roughly includes two main girders 2 extending in a bridge axis direction C, a cross beam 3 extending in a direction orthogonal to the main girder 2, and a highly-durable concrete floor slab 4 disposed on the upper part of the main girder 2. The highly-durable concrete floor slab 4 comprises a plurality of highly-durable concrete floor slab panels which are disposed in the bridge axis direction C and the direction orthogonal to the bridge axis direction C. The highly-durable concrete floor slab panel is constituted of a panel in which steel materials such as a bottom steel plate 8, a reinforcing bar, a rib are embedded in the concrete, and is preliminarily manufactured in a factory, or the like.;COPYRIGHT: (C)2012,JPO&INPIT
