Abstract

PROBLEM TO BE SOLVED: To reduce cost and save labor for a work by integratedly forming first and second spring pieces on the outside of a cylindrical supporting tool, and fitting a buried tool inside the upper part of the cylindrical supporting tool. SOLUTION: This insert for building is constituted so that first spring pieces 2 projecting in chevron downward on the right and left of the upper part, and second spring pieces 3 projecting chevron-likely upward on the front and rear of the lower part, are formed integratedly with the outside of a cylindrical supporting tool 1, and a buried tool 4 integratedly provided with a flange-like anchor part 5 and a female screw part 6 is fitted inside the upper part of the supporting tool 1. Next by pushing this insert in the through hole of a deck plate formwork P from the lower end of the supporting tool 1, the spring pieces 2, 2 are pushedly spread out, the spring pieces 3, 3 are once made narrower, restored simultaneously with passing the through hole, and hence it is fitted in the condition of pressing the formwork P from both sides. Because the insert is constituted of two parts, the supporting tool 1 and buried tool 4, the cost can be reduced, easily supported with the formwork P by spring action of the spring pieces 2, 3, and the labor saving of the work can be attained.
