ANCHOR DEVICE FOR SCREW REINFORCEMENT

摘要

PROBLEM TO BE SOLVED: To enable an anchor metal member for anchoring a screw reinforcement to concrete to be fitted to the screw reinforcement without the use of grout. SOLUTION: An anchor device 1 is equipped with the anchoring metal member 10 and a fixing bolt 19. The metal member 10 comprises a tube 11 wherein an internal thread 14 is formed on an inner periphery, an end wall 12 for closing one end of the tube 11, and an annular flange 13 which overhangs in radial and outward directions from the tube 11. A threaded hole 16 is formed in the center of the end wall 12. The thread pitch of the threaded hole 16 is smaller than that of the internal thread 14 of the tube 11. The fixing bolt 19 is screwed into the threaded hole 16 of the end wall 12, and pushes the end surface of the screw reinforcement 40 which is screwed into the tube 11 of the metal member 10 so that the thread 14a of the tube 11 can be pushed against the thread 41a of the screw reinforcement 40.
