BRICK JOINING PART

PROBLEM TO BE SOLVED: To simply join bricks to one another in laying bricks so that the joined bricks may be effectively efficacious against external force such as a quake or tension for a stacked-together structure to be weak. SOLUTION: In execution of works, a part of a shaft and a return disposed in at least two places of one brick is inserted in a hole part of a lower perforated brick, mortar for a joint is applied with reference to the thickness of a collar 3, a shaft 1 and a barb 2 are inserted in a hole of an upper perforated brick too, and bricks are sequentially stacked. Thus, two or more shaft and return parts are arranged to join the whole of bricks, and especially the barb 2 is efficacious tension.
