CONNECTING SECTION STRUCTURE OF CORRUGATED STEEL PLATE AND CONCRETE FLOOR SLAB IN CORRUGATED STEEL-PLATE WEB PC BOX GIRDER BRIDGE

摘要

PROBLEM TO BE SOLVED: To avoid the change of the size of a PC box girder bridge component, ensuring shear resistance force in the same as or more as a large number of stud dowels are used when the integrality of a corrugated steel plate and a concrete floor slab is assured in the PC box girder bridge in which the corrugated steel plate is used for a web.;SOLUTION: Flange plates 5 are welded in the longitudinal direction of the corrugated steel plate 3 at the upper end and lower end of the steel plate 3, perforated steel-plate dowels 6 in a shape that holes 61 are bored at intervals in the longitudinal direction of plates 60 are welded vertically to the flange plates 5 along the longitudinal direction of the flange plates 5 on surfaces on the concrete floor slab 1, 2 sides of each flange plate 5, and the perforated steel-plate dowels 6 are buried into the concrete of concrete floor slabs 1, 2.;COPYRIGHT: (C)2000,JPO
