TIE BOLT FOR SUSPENDING FLOOR BOARD-RECEIVING BEAM IN CONCRETE CONSTRUCTION OF BRIDGE GIRDER, AND INSTALLATION METHOD OF TIE BOLT FOR SUSPENDING FLOOR BOARD-RECEIVING BEAM IN CONCRETE CONSTRUCTION OF BRIDGE GIRDER

摘要

PROBLEM TO BE SOLVED: To provide a tie bolt for suspending a floor board-receiving beam in concrete construction of a bridge girder, which allows the tie bolt to be easily pulled out after concrete curing, and an installation method of a tie bolt for suspending a floor board-receiving beam in concrete construction of a bridge girder.

SOLUTION: A tie bolt for suspending a floor board-receiving beam comprises: an upper-side male screw part 11 for suspension from a floor board-suspending piece and an upper-side nut 12 screwed with the upper-side male screw part 11 on the upper end side of a bolt body 1; and a lower-side male screw part 13 for support of a concrete form floor board and floor board-receiving beam and a lower-side nut 14 screwed with the lower-side male screw part 13 on the lower end side of the bolt body 1. At least a part of the bolt body 1 to be embedded in concrete has the outer periphery provided with a synthetic resin pipe 6.
