STEEL PLATE FLOOR FOR BRIDGE, AND METHOD OF MANUFACTURING STEEL PLATE FLOOR FOR BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a steel plate floor for a bridge that can improve safety by retarding fatigue cracking of the steel plate floor for the bridge from a root of a U-rib weld zone of a deck plate and then preventing a steel plate floor for a steel-made bridge from decreasing in strength, and also can reduce repair cost by making repair intervals of the steel-made bridge long, and a method of manufacturing the steel plate floor for the bridge.;SOLUTION: There are provided the steel plate floor for the bridge characterized in that a deck plate-side end of a U rib is curved to contact a deck plate, and a length (L and/or L') of the curved part is equal to or larger than a thickness (t) of the U rib, and the method of manufacturing the steel plate floor for bridge.;COPYRIGHT: (C)2013,JPO&INPIT
