DRAIN GUTTER FOR ROAD BRIDGE EXPANSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a novel drain gutter for a road bridge expansion device causing no problem of drain such as rainwater falling under a girder. SOLUTION: The drain gutter for the road bridge expansion device is disposed in a girder expansion gap directly under the road bridge expansion device provided between facing side plates, and formed of a constitutive material with rubber elastic properties. The drain gutter has a pair of arm parts joined to the facing side plates respectively, and a drain passage is formed on the upper face. It is preferable to have a cavity part extending in the length direction of the drain gutter, inside the drain gutter. COPYRIGHT: (C)2006,JPO&NCIPI
