SECTION STEEL AND WALL BODY USING THE SECTION STEEL

摘要

A section steel having excellent adhesion to concrete and a wall body allowed to reduce the wall thickness thereof, the section steel in H-shape comprising a plurality of projections on the inner surfaces thereof, wherein where the upper side width of the projections is b2, the height of the projections is h, the pitch of the projections is P in a section vertical to the surfaces of the H- steel having the projections thereon, the requirements of P/h= 4 can be satisfied. The wall body using the H- steels as structural members is formed by vertically installing the plurality of H-steels in the longitudinal direction of the wall body with the flange outer surfaces thereof facing the wall surfaces of the wall body.
