HOLE FINISHING METHOD

PROBLEM TO BE SOLVED: To provide a hole finishing method capable of eliminating production of a plate member for each through hole, use of fire in the work and removal work of a trace of an inflow/outflow opening of a filler. SOLUTION: According to the hole finishing method, in order to fill a thorough hole 52 which is provided for passing a pipe 54 in a concrete wall 50, a sleeve 40 is arranged in the thorough hole 52 and plate members 10 are pushed from both sides of the concrete wall 50 while the filler is filled between the pushed plate members 10. A threaded bolt 32 is passed through a pair of the plate members 10 which are arranged for sandwitching the wall 50, so as to generate a pushing force by tightening a nut 34 to the threaded bolt 32. The plate member 10 can be separated, and the separated piece 12 has a notched part 15 for ventilation of air in the thorough hole 52 also as an inlet of the filler. In the notched part 15, a partition plate is placed after the filler is inserted, and after the filler is hardened, the partition plate and the plate member 10 are removed. Also, the threaded bolt 32 protruded from the hardened filler is cut off. COPYRIGHT: (C)2010,JPO&INPIT
