REPAIRING METHOD OF EXISTING CONCRETE STRUCTURE AND CONSTRUCTION METHOD OF NEWLY PROVIDED CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To perform repair or construction of a concrete structure without breaking fitting holes and the like by providing side by side wall materials such as fiber reinforced concrete plates formed with fitting holes in which fixing bolts are inserted from a repairing face while keeping a distance. ;SOLUTION: A fiber reinforced concrete plate 1 is spacedly arranged from a repairing face 4 so that the side of small fitting hole diameter is provided on the inside. Next, an anchor bolt 6 is inserted from the fitting hole 2 toward the repairing face 4, and fixed to a fixing part 5. Next, the space between the fiber reinforced concrete plate 1 and the repairing face 4 is filled with filler such as mortar or grout and hardened. At the filling, because the fitting hole 2 is blockaded with the head part 7 of the anchor bolt 6 and seal material, the filler 8 does not leak. Hereby it is high in strength even if it is thin in the wall thickness, and the filling work can be performed without breaking the fitting hole 2.;COPYRIGHT: (C)1999,JPO
