SPRING SPIRAL REINFORCEMENT AND ARRRANGING METHOD AND ARRANGING STRUCTURE THEREOF

PURPOSE:To facilitate the work of operating a series of reinforcement by inserting a spring spiral reinforcement spirally formed to be extensible into reinforcements arranged in a meshy form. CONSTITUTION:A spring spiral reinforcement 1 formed in a spiral shape having a required length and formed to be extensible in the longitudinal direction is inserted into the meshes 3 of reinforcements 2 under the state in which the spring spiral reinforcement 1 is shrunk. The lateral direction or the vertical direction is selected arbitrarily as the insertion direction of the spring spiral reinforcement 1 at that time. The spring spiral reinforcement 1 inserted into the meshes 3 is extended, and rotated under the state, and arranged so as to wind a steel material 4 at the specified position of the steel material 4. The end section of the arranged spring spiral reinforcement 1 is bundled, thus completing operation. Considerably long-sized reinforcements 1 are divided previously into two or three when the reinforcements 1 are inserted into the meshes 3 of the reinforcements 2, the reinforcements 1 previously inserted so as to wind the steel materials 4 are inserted under a shrunk state when the reinforcements 1 of a final block are inserted, the existing reinforcements 1 are elongated, and the reinforcements 1 of the final block are bundled with the existing reinforcements 1.
