Abstract:
A method for reinforcing an existing wall structure comprising the steps of:attaching steel segments in a plurality of stages onto a wall surface of the existing wall structure, each of said steel segments being formed into a column having a continuous cross-section in the shape of a circular-arc, and being integrally provided with flanges for connection on both sides of each circular-arc column in the width direction;allowing a plurality of PC steel bars to pass through a plurality of holes pierced in said flanges and through a plurality of holes pierced through the existing wall structure in the direction of the thickness, and screwing end portions of said PC steel bars having been passed through said flanges and the existing wall structure to fix said steel segment onto the wall surface; andplacing concrete in the circular-arc protruded spaces between said steel segments and the wall surface to integrate said steel segments onto the wall surface of the existing wall structure;characterized in:providing reinforcing bodies on end surfaces, in the direction of the thickness which is perpendicular to the wall surface of the existing wall structure; andconnecting said reinforcing bodies to the end portions of said steel segments.
