In FIG. 1 and FIG. 2, a support member 1 is a portion that is erected on a reinforcing bar 5 serving as a support of a concrete wall. The support member 1 can be manually bent, and the bending direction can be freely set. Regarding the specific shape of the linear support member 1, various shapes such as a circular cross section, a square cross section, and a flat cross section are conceivable. Particularly, the ease of erection on the rebar 5 forming a skeleton, In addition, the one with a circular cross section is excellent in terms of flexibility in the bending direction. Specifically, it is commonly called a No. wire, and among them, the mild steel wire around the No. 8 wire is most suitable. The support member 1 has a tensile strength capable of pressing the embedded object main body against the formwork in a bent state, and as shown in FIG.
When the support member 1 is pressed against the formwork 6, the support member 1 is bent in a direction indicated by an arrow 62 in a state in which the support member 1 is bent in response to a force applied to the embedded object body 4 in the direction indicated by an arrow 61. It has a pressing force to make the embedded object main body 4 stretch. In this state, the buried object main body 4 is kept pressed against the formwork 6 by the support member 1, in other words, is kept in close contact.
