PROBLEM TO BE SOLVED: To solve the following problem: a conventional method for bonding stone to the surface of a concrete block to form a natural stone surface is problematic in load yield strength, and it is difficult to secure complete safety against peeling caused by the change of temperature and humidity for a block etc., to be set in a high place. SOLUTION: A shaft part 2 is formed on a bonding surface by inserting the head part into a T-channel 11 engraved in the bonding surface. The stone with a T-bolt fitted with washers 3 holding edge parts 13 on both sides of the T-channel between them in the shaft part made as a bonding foundation is placed at a prescribed position of a molding form. By pouring/molding concrete into/in the form, the stone is bonded to a prescribed surface of the concrete block. COPYRIGHT: (C)2005,JPO&NCIPI
