BREADTHWISE STEP HEIGHT CONSTRUCTION METHOD OF DECK PLATE WITH REINFORCEMENT TRUSS

摘要

PROBLEM TO BE SOLVED: To provide a breadthwise step height construction method of a deck plate with a reinforcement truss, for dispensing with a support by eliminating construction of a beam in a step height part.;SOLUTION: This breadthwise step height construction method comprises a process of arranging a lower stage side deck plate 10 with the reinforcement truss and an upper stage side deck plate 30 with the reinforcement truss by arranging a step height, a process of blocking up a clearance formed in the step height by using a step height processing metallic material 50, a process of allowing a lower stage lower chord member 22 to abut on a flange 62 by inserting a lower stage upper chord member 21 of a lower stage reinforcement truss 20 into a through-hole 61 of a step height tool 60, by placing the step height tool 60 in the step height part of the lower stage deck plate 10, and allowing a step height lower chord member 72 of a reinforcement truss 70 for the step height part to abut on a flange 62, by placing a step height upper chord member 71 of the reinforcement truss 70 for the step height part, and a process of placing concrete so as to wrap the reinforcement truss 70 for the step height part in the lower stage deck plate 10 and the upper stage deck plate 30.;COPYRIGHT: (C)2008,JPO&INPIT
