The present invention relates to a box having a mounting structure.

(Prior art) Conventionally, for example, in order to attach an electrical wiring box to a bar and hide it inside a lightweight partition wall, support bolts 5 are strung between lightweight steel 6 as shown in FIG. The box 1 is supported by holding the support bolt 5 between the support metal fitting 9 and the back side 8 of the box by tightening a separate support metal fitting 9 that sandwiches the support bolt 5 with the screw 7 to the back side 8 of the box. After attaching to the bolt 5, the lightweight steel 6
Walls were erected from both sides to sandwich the box.

(Problem to be Solved by the Invention) However, when the conventional box is attached to a bar, the bar 5 and the support fittings 5 protrude from the back surface of the box. There was a problem that the box could not be installed within the wall because it did not fit within the wall thickness.

This problem similarly occurs when the box is installed within a concrete formwork in order to bury the box within a concrete wall.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a box that can be installed inside a thin wall and has a structure for attaching to a bar that can be installed without being affected by obstacles outside the box. be.

(Means for Solving the Problem) In order to achieve the above object, the box according to the present invention is a box that stores wiring equipment etc. inside and is attached to a bar and installed inside the wall of a building. a bar insertion hole that is bored in a side wall of the box and has a size that substantially corresponds to the bar so that the bar passes through the box; and a bar insertion hole that is inserted into the bar insertion hole and inserted into the box and a fixing means for fixing a rod that has passed through the box, and the rod insertion hole is located near the bottom of the box in order to secure a storage space for wiring devices, etc. stored in the box with the rod passing through the inside of the box. It is characterized by the fact that it is formed in

(Function) With the above configuration, in order to attach the box according to the present invention to a bar, a bar such as a reinforcing bar or a bolt is inserted into the bar insertion hole of the box and passed through the inside of the box to make the bar lightweight. Fix it to a structure such as shaped steel.

Next, the box is fixed to the bar by means of a fixing means that fixes the bar passing through the inside of the box.

Therefore, according to the box of the present invention having the above-mentioned configuration, since the bar is placed inside the box, the box can be installed inside the wall of a building without having the bar, support fittings, etc. protrude from the back side of the box. .

(Example) Hereinafter, an example of an electric wiring box embodying the present invention will be described with reference to the drawings.

The electrical wiring box 1 shown in FIGS. 1 and 2 is made of metal, and the opposite side walls of the box are cut inward at opposite points near the bottom of the box perpendicularly to the side walls. By raising it up, a bar insertion hole 2 is formed and a tongue piece 3 is provided in a protruding manner.

This rod insertion hole 2 is formed in a size that approximately corresponds to the later-described rod used to support the electrical wiring box 1, and a screw hole 4 is formed through the tongue piece 3. It is formed.

Now, a method of constructing the electric wiring box 1 will be described below, taking as an example a case where the electrical wiring box 1 is hidden and installed within a lightweight partition wall.

First, as shown in FIG. 3, a support bolt 5, which is inserted into the bar insertion hole 2 of the box 1 and passes through the inside of the box 1, is stretched across the lightweight steel 6 and fixed.

Next, as shown in FIGS. 4 and 5, a screw hole 4 provided in the tongue piece 3 is used as a means for fixing the bar.
Insert the screw 7 from the opening of the box 1, tighten it with a screwdriver, etc., and press the lower end of the screw 7 against the outer surface of the support bolt 5. The box 1 is clamped and fixed to the support bolt 5.

Thereafter, walls are erected to sandwich the box 1 from both sides of the lightweight type steel 6, and the box 1 is hidden and installed within the lightweight partition wall.

Then, a through hole is bored at a predetermined location in the formed lightweight partition wall so that the opening of the box 1 faces the surface of the lightweight partition wall, and wiring equipment and the like are housed in the box 1 through the through hole.

Here, the bar material insertion hole 2 of the box 1 is inserted into the box 1 so that the bar material inserted therein passes through the inside of the box 1 to secure a storage space for wiring devices, etc. stored in the box. Since it is formed near the bottom of the side wall, when storing the wiring equipment in the box 1, the support bolts 5 in the box 1 will not become an obstacle and prevent the wiring equipment etc. from being stored.

Next, a case will be described in which the box of this embodiment is installed in a concrete formwork in order to be buried in a concrete wall.

When burying in concrete, as in the case of concealment, first, a support reinforcing bar cut to a predetermined length is inserted into the bar insertion hole 2 of the box 1 to pass through the inside of the box 1, and the bar fixing means is inserted. As, tongue piece 3
Tighten the fixing screw into the screw hole 4 provided in the
Fix box 1 to the supporting reinforcing bars.

Next, the supporting reinforcing bars to which the boxes 1 are fixed are stretched and fixed between the vertically and horizontally arranged support reinforcing bars.

After that, concrete formwork was erected and formed so as to sandwich box 1 from both sides of the strut reinforcement.
Concrete is poured into the formwork.

Since the bar insertion holes 2 are formed to have a size that substantially corresponds to the support reinforcing bars, it is possible to prevent concrete from entering the box 1 from the bar insertion holes 2.

Note that the bar referred to in the present invention is not limited to the bolts or reinforcing bars described in the above embodiments, and may have a cross-sectional shape other than a round bar, such as a flat plate or a square bar.

Further, in the above embodiment, the box is made of metal, but the box and the cut-and-raised piece may be integrally formed of resin, and the material of the box is not limited in any way.

Further, in the above embodiment, the shape of the box is described as being square, but it is not limited to this, and may be round or elliptical, and the shape is not limited in any way.

In addition, in the above embodiment, as a means for fixing the box to the bar, a screw is inserted into a screw hole formed in a cut-and-raised piece to clamp the bar. The box may be fixed to the bar by fixing a separate fixture to the bottom of the box, and if a means for fixing to the bar passing through the inside of the box is provided, what is the fixing means? Not limited.

The boxes to which the present invention is applied include, in addition to electrical wiring boxes that house electrical wiring equipment, etc., there are also fluid piping boxes that house joints and the like through which fluids such as hot water, water, and gas pass.

(Effects of the Invention) As described above, according to the box according to the present invention, the rod is bored in the side wall of the box with a size substantially corresponding to the rod so that the rod passes through the inside of the box. Since it is equipped with a bar insertion hole and a fixing means for fixing the bar that has passed through the bar insertion hole and penetrated the inside of the box, it is possible to attach the bar to the bar without protruding any part of the bar or supporting metal fittings outside the box. This makes it possible to install the box even if the wall on which it is installed is thin, and also prevents concrete from entering the box through the bar insertion hole when the box is buried in concrete. It can be prevented.

In addition, the rod insertion holes are formed near the bottom of the box so as to secure storage space for wiring devices, etc. that are stored in the box with the rod penetrating the inside of the box. The bar that passes through the box does not become an obstacle when storing wiring devices, etc. in the box.

Furthermore, if the box having the structure described in the above embodiment is used, it can be attached to the support rod without using a separate support fitting as in the conventional case.
By reducing the number of parts, costs are reduced and work efficiency is significantly improved.
