METHOD AND STRUCTURE FOR PREVENTING WATER LEAKAGE OF FLOOR JOINT IN BUILDING

摘要

The present invention relates to a method and a structure for preventing a water leakage through a floor joint of a building. The method of preventing the water leakage through the floor joint, which is a floor boundary of upper and lower walls forming an outer wall of the building constructed by placing concrete into molds, includes: a step of arranging lower wall rebar for reinforcing the lower wall in a space between an inner wall mold and an outer wall mold and installing a groove unit frame on the upper inner surface of the outer wall mold; a step of forming a key-groove unit at a depth deeper than the width thereof in an upper part of the lower wall by removing the inner wall mold, the outer wall mold, and the groove unit frame after placing and curing concrete into the space; a step of connecting upper wall rebar to the lower wall rebar protruding upward from the upper part of the lower wall and arranging the bottom of the upper wall rebar to be adjacent to the bottom of the key-groove unit; and a step of interlocking a key unit protruding from the lower part of the upper wall to be integrated with the key-groove unit of the upper part of the lower wall when forming the upper wall on the top of the lower wall.
