MOUNTING STRUCTURE OF WALL SURFACE BLOCK PANEL AND WALL SURFACE BLOCK PANEL

PROBLEM TO BE SOLVED: To provide a mounting structure of a wall surface block panel requiring less labor for the construction even when decorative parts such as shelf boards and shelf columns are arranged at the front of the wall surface block panel. SOLUTION: In this mounting structure, screw holes allowing mounting screws inserted therethrough are longitudinally formed in the wall surface block panel. Each screw hole has a small diameter hole allowing the body part of the screw to be inserted therethrough and a large diameter hole formed continuously with the small diameter hole through a step surface abutting on the head part of the mounting screw and allowing the head part of the mounting screw to be inserted and stored therein. First recessed grooves opened forward with the large diameter hole positioned at the center on the front side of the large diameter hole and each having a width larger than the diameter of the large diameter hole are radially formed to the outer peripheral end part. Second recessed grooves are so formed in the longitudinal intermediate part of the first recessed grooves as to be positioned along the first recessed grooves and recessed in the direction along the wall surface, respectively.
