Summary: | PROBLEM TO BE SOLVED: To provide an excellent crack preventive function by forming a plurality of long reinforcing bars and a plurality of short reinforcing bars into a grid by integrally welding them to one body. SOLUTION: A unit 1 comprises many short reinforcing bars 3 are assembled to three long reinforcing bars 2 and integrated to one body by welding. In this reinforcing bar unit 1, the long reinforcing bars 2 is arranged in parallel with the longitudinal direction of a beam, and the short reinforcing bars 3 are arranged in parallel with the wall face of a wall, and they are incorporated in the inside of a wall reinforcing bars with a specified thickness of overburden. When a crack is produced in the wall in which the reinforcing bar unit 1 is thus arranged, a load is applied to the short reinforcing bars 3, but since this load is surely supported by the short reinforcing bars 3 which are integrated with the long reinforcing bars 2 by welding. As a result, the production of a crack in this wall can effectively be prevented, and even if a crack is produced, an increase in the width of the crack can effectively prevented. |
