ERECTION STRUCTURE OF FLOOR SLAB FOR BRIDGE

摘要

PURPOSE:To unify respective adjacent floor slabs as a unit in both lengthwise and breadthwise directions of a bridge, by constituting the floor slabs with parallelogram floor slabs with diagonal sides and isosceles triangle floor slabs and fastening the adjacent floor slabs in the breadthwise direction of the bridge by laterally fastening PC steel members. CONSTITUTION:A parallelogram floor slab 2 with four diagonal sides 1 is arranged so that a pair of tops 3 are positioned at the central part of the breadthwise direction of a bridge and tune floor slab 4 of the nearly isosceles triangle is inserted between the parallelogram floor slabs adjacent in the longitudinal direction of the bridge and laterally fastening PC steel members 5 are inserted over the adjacent floor slabs 2, 4 in the breadthwise direction of the bridge. the parallelogram floor slab 2 and the isosceles triangular floor slab 4 adjacent to each other in the breadthwise direction of the bridge are unified by the laterally fastening steel members 5.
