SUBSTRATE TREATMENT STRUCTURE OF WALL SURFACE

摘要

PROBLEM TO BE SOLVED: To provide substrate treatment of a wall surface, which increases fixing strength of furring strips around an opening of a lightweight concrete wall surface. SOLUTION: In this substrate treatment structure of the wall surface 6 around the opening 5 of the lightweight concrete wall surface 6, the L-shaped furring strips 10, into which a screw is inserted in a position with a distance from an inward curved edge 1a longer than a distance from an L-shaped outward curved edge 1b are provided on the wall surface 6 along a corner part of the opening 5.
