Disposed structure of the wiring box, concrete wall that was buried wiring box, and its construction method

摘要

PROBLEM TO BE SOLVED: To provide an arrangement structure of a wiring box capable of easily embedding various wiring boxes by utilizing a concrete formwork method, a concrete wall body in which a wiring box is embedded, and a method of constructing the concrete wall body.SOLUTION: In an inventive arrangement structure of a wiring box, at least a part of a rod-like member (2B) of a spacing member 2 positioned in a concrete placement space 5 is surrounded by a cylindrical member 2C, and the spacing member 2 can be extracted after concrete 5 is placed. A wiring box 1 is made as a box-shaped body having at least an opening surface and a bottom face 13 in which a through-hole 131 for penetration of the spacing member 2 is formed. The rod-like member 2B is fastened to a holding member 7 arranged outside a form 3A, thereby bringing a rear face (13) side of the wiring box 1 into contact with the cylindrical member 2C and a front side thereof into contact with the surface of the form 3A in a sandwiching manner to form a concrete placement space 5. Then, the wiring box 1 is fixedly attached to reinforcements 6 or an adjacent spacing member by coupling tools 9.
