METHOD FOR REINFORCING LOAD-BEARING WALL AND SHEAR REINFORCED LOAD-BEARING WALL

摘要

The present invention relates to a method for reinforcing a load-bearing wall and a shear reinforced load-bearing wall that increases shear strength and shear deformation ability to achieve earthquake-proof performance of the load-bearing wall made of concrete. The method includes: an inspection step of non-destructively inspecting a predetermined section for reinforcing a load-bearing wall, and determining a construction area on a front surface of the load-bearing wall; a groove forming step of, in order to insert a reinforcing plate made of a rectangular steel plate for reinforcing shear strength of the construction area and provided with a plurality of spacers elongated in a longitudinal direction and spaced apart from each other at regular intervals, forming a first area by cutting the front surface of the load-bearing wall around a front rebar, as a connection space of the front bars positioned in front of the front of the load-bearing wall, to expose the front rebars, cutting the front rebars crossing a position where the reinforcing plate is positioned, forming a second area from the first area in the load-bearing wall to rear rebars, without exposing the rear rebars, to form a ┴-shaped or ├-shaped insertion groove; an insertion step of inserting and fixing the reinforcing plate in the second area of the insertion groove; a rebar connecting step of connecting the exposed front rebars by connecting members or coupler members; and a recovery step having a front surface constructing step of constructing mortar or concrete/mortar on the first area which is a connecting space around the groove, and a filling step of filling a gap between the second area of the insertion groove and the reinforcing plate with resin.;COPYRIGHT KIPO 2018
