ラインの設置面積の有効利用が計れる等の効果がある。According to the first manufacturing method of the related art, it takes four hours per sheet for two workers after the welding of the welded rebar bent into a ring shape. In the second manufacturing method, the welding is performed integrally. After carrying in the outer rebar, it took about 2.5 hours per sheet for two workers, but with the manufacturing method of the present invention, after the outer rebar is carried in, there is no danger as in the past and light work that does not require heavy labor. There is an effect that one worker can complete one in about 30 minutes,
Further, by applying the insertion device of the present invention, since there is no standing posture such as leaning forward, middle waist, etc., it is possible to prevent the occurrence of back pain of the worker, fatigue and injury of the limbs, etc., and labor saving to eliminate the worker shortage ( Labor saving) and the cost reduction of the wire net for underdrain block due to the shortening of the manufacturing time, and the assembly accuracy is improved, which has the effect of exceeding the capital investment. The ones according to claims 3 and 4 are installed on both sides of the outer reinforcing bar. The amount of welding machines (welding robots) that need to be moved can be reduced, and the number of welding machines can be reduced, or the loading line can be installed vertically and horizontally, and the effective use of the production line installation area can be achieved. .
