PROBLEM TO BE SOLVED: To provide a wall-shaped structure joint which is easy to set and secures desired durability and integration in wall structure, while dispensing with repairing even when a wall-shaped reinforcing concrete building such as a wall handrail and a ground cover of a road bridge undergo cracks penetrating through the cross section of the structure. SOLUTION: A crack trigger joint using a reinforcing stainless-steel bar is set to the wall-shaped structure such as the wall handrail and the ground cover of the road bridge, at 3 to 10 m intervals so as to be equally spaced in the extension direction of the wall. The reinforcing stainless-steel bar formed into a square-shape in the cross sectional direction of the wall is arranged, and also a notch such as a joint bar or the like is set on the front surface side of the wall, the joint causes the wall cross sectional area to be chipped, configured to trigger cracking at the joint portion. Furthermore, a reinforcing stainless-steel bar high in a corrosion-proof property is disposed at the joint portion in a direction orthogonal to the cracking surface, configured to secure structural continuity at the cracking position of the wall-shaped structures.
