GIRDER FOR ADJUSTING SECTION RIGIDITY AND BRIDGE

摘要

PURPOSE: a kind of to be applied to field condition by being equipped with rigid adjustment section, for the loading concrete according to differential adjustment section rigidity for adjusting combined bridge rigidity and providing the part optimized comprising the bridge. ;CONSTITUTION: a kind of bridge (100) includes girder steel and rigid adjustment portion (130) for adjusting sectional rigid main body. The beam body is formed with hollow inside. It includes pipe portion part, bent member, subregion, filling hole, tension member (135) that the rigidity adjustment section, which is equipped in hollow space,. Pipeline and bending component are separately fixed and are attached to the lower surface and in beam body. Pipeline and bending component are by the filling space of (131). Subregion adheres to internal web, in the beam ontology. The rigidity pours into filling space with concrete by adjusting loading. ;The 2013 of copyright KIPO submissions
