Document Type and Number:

Japanese Patent JP2016065569

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an opening part closing method capable of performing a simple, easy and fast opening part closing stage and realizing a positive anti-water leakage seal.SOLUTION: After arranging a pipe in a pipe hole formed at a floor slab of a building, an opening part closing member is adhered to a lower surface of the floor slab, a closing member is filled from an upper side of the pipe hole between an outer peripheral surface of the pipe and an inner peripheral surface of the pipe hole to close a pipe penetration part. Damper material is filled between the inner peripheral surface of the pipe hole and an outer peripheral surface of the pipe from above the pipe hole, cement mortar is filled from above the pipe hole up to a height of an upper surface of the floor slab and hardened between the inner peripheral surface of the pipe hole and the outer peripheral surface of the pipe after the damper material is filled.SELECTED DRAWING: Figure 1
