INSERTION METHOD FOR ANCHOR TENDON, ANCHOR TENDON SUPPORT UNIT AND ANCHOR TENDON BASE

摘要

PROBLEM TO BE SOLVED: To prevent the damage to a boundary part of an anchor body length part and a free length part in the case of inserting an anchor tendon whose top end (anchor body length part) is pre-grouted into an anchor hole.

SOLUTION: An anchor body length part 30 is supported by a top end support body 40 as a sufficient rigid member which does not affect the anchor body length part hardened with grout when it is hanged by a crane, and a free length part 31 is conveyed in a state that it is supported by an intermediate part support body 41 as a flexible member. Those top end support body 40 and the intermediate part support body 41 are connected, and the intermediate support body 41 is structured such that deformation does not become a predetermined curvature radius or less. The boundary part of the anchor body length part and the free length part can be protected, and damage thereto can be prevented by those support bodies 40 and 41.
