There is a particular thing.

(composition) First, the erection tool according to the present invention will be explained.

The erection tool according to the present invention is constructed separately from the buried object and is used by being attached to the buried object. The erection tool according to the present invention includes a linear support part that can be bent by hand and has a tensile strength that can press an embedded object against a formwork in a bent state, and a linear support part that is embedded in a concrete wall. It consists of a mounting part that is attached to the buried object.

EMBODIMENT OF THE INVENTION Hereinafter, the erection tool based on this invention is demonstrated according to a drawing.

In FIGS. 1 and 2, the support part (1) is a part installed on reinforcing bars (5) that form the support frame of a concrete wall. The support part (1) can be bent by hand, and the bending direction can be freely set. As for the specific shape of the linear support part (1), various shapes can be considered, such as a shape with a circular cross section, a square shape, or a flat shape.
In particular, those with a circular cross section are excellent in terms of ease of installation on the reinforcing bars (5) that form the support frame, and flexibility in bending direction. Specifically, it is commonly called a wire, and among them, mild steel wire around number 8 is optimal. In addition, the support part (1) has a tensile strength that can suppress the buried object in the formwork in a bent state, and as shown in FIG.
4) is pressed against the formwork (6), when the buried object (
4), the buried object (4) is stretched in the direction of the arrow (82) in a state where the support part (1) is bent in response to the force in the direction of the arrow (81). It has power. In this state, the buried object (4) is
), it is kept pressed against the formwork (8), in other words, kept in close contact with it.

The supplement part (2) has a structure for attaching the support part (1) to the buried object (4). There are numerous methods of attachment, including attachment with screws and attachment by fitting. The shape of the attachment part (2) takes various forms depending on the external shape of the buried object (4). However, as shown in Figure 2, the buried object (electrical wiring box) (4) has a supporting part (
