ANCHOR MEMBER ANCHORAGE METHOD OF EXISTING CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an anchor member anchorage method of an existing concrete structure, capable of stably filling the inside of an anchor insertion hole with a filler such as mortar while suitably exhausting air from the inside of the anchor insertion hole, and surely connecting a new member to an existing concrete body.;SOLUTION: After an anchor insertion hole 10 is formed in an existing concrete structure 1, anchor members 3, 3... are inserted into the anchor insertion hole 10 in a state that a tip of a fixed type outer pipe 6 is fixed and an air exhaustion inner pipe 7 is inserted into the fixed type outer pipe 6 in a movable manner. The air exhaustion inner pipe 7 is extended until its tip opening part 7a abuts on the inside upper end part of the anchor insertion hole 10, and thereafter the inside of the anchor insertion hole 10 is filled with a filler 13 while exhausting air from the inside of the anchor insertion hole 10 through the air exhaustion inner pipe 7.;COPYRIGHT: (C)2014,JPO&INPIT
