Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture used to fix a wiring box buried in a concrete wall or a concrete ceiling of a building to a formwork.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional example of this wiring box fixture (see Japanese Utility Model Laid-Open No. 52-153895). The fixture 1 is made of a metal plate formed in a substantially U-shape, the center portion 21 of which serves as a stop portion of the wiring box 7, and each end portion 23 of both legs 22 and 22 is bent outward to form a frame. It is a mounting part for 8. The central portion 21 serving as the wiring box fixing portion is fixed to the bottom surface 71 of the wiring box with screws 61, and the bent end portion 23 serving as the mold frame mounting portion is formed with the nails 62. Fixed to.

[0003]

However, in this conventional wiring box fixing tool, the mounting height position of the wiring box 7 cannot be adjusted when the wiring box 7 is mounted because the length of the foot 22 is constant. In order to fix the sheet metal directly to the form 8,
After the concrete is cured, there is a problem that the sheet metal is exposed from the concrete surface and causes rust.

[0004] Therefore, an object of the present invention is to provide a wiring box fixing tool capable of adjusting the height of the wiring box and less likely to cause rust.

[0005]

In order to solve the above-mentioned problems, a wiring box fixing device according to the present invention is provided with a main body made of sheet metal formed in a U-shape, and a mounting base for the mold. The main body of the main body serves as a fastening portion for the wiring box, has a screw hole for fixing a screw to the bottom of the wiring box, and has a plurality of notches that can be cut by bending on both legs. The mounting base has a slit for inserting a foot end portion of the main body and a nail hole for nailing to the form, and a screw for temporary fixing is provided between the main body and the mounting base. A hole is formed.

[0006]

[Function] When the foot end of the main body has a plurality of cutouts that can be cut by bending, the cutouts are used to cut the legs and adjust the length of the legs, thereby increasing the height of the wiring box. The height can be adjusted. If the mounting base is removed together with the formwork, the sheet metal remains buried in the concrete, and rust is unlikely to occur.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a wiring box fixture according to the present invention. The fixture 1 includes a main body 2 formed of a U-shaped sheet metal and a mounting base 3 for the mold.
It has and. The center portion 21 of the main body 2 serves as a fixing portion for the wiring box 7, and here, the wiring box bottom surface 7 is provided.
1 has a screw hole 21a for fixing with a screw 61, and has a plurality of notches 22a at both legs 22, 22 thereof that can be cut by bending. Mounting base 3
Has a slit 31 (concave groove) for inserting the foot end of the main body 2 and a nail hole 32 for fixing to the formwork with a nail 62. Then, a screw 63 is provided between the main body 2 and the mounting base 3.
Screw holes 22b and 33 for temporary fixing are formed.

Considering the concrete thickness and the thickness (depth) of the wiring box, the length of the foot 22 of the main body 2 is determined, and the notch 22a is used to cut the foot 22 with a tool such as pliers. Adjust the length. The thickness of the sheet metal should be set in consideration of the ease of this cutting work. After adjusting the leg length of the main body 2 in this manner, the central portion 21 of the main body 2 is coupled to the wiring box 7 using the screws 61. On the other hand, the mount 3 is nailed in advance to one of the molds 8. Then, as shown in FIG. 2, the other end of the main body 2 is inserted into the hole of the mounting base 3 (including press-fitting), and the wiring box 7 is inserted.
Is fixed to the form 8. In addition, screw holes 3 provided on the mounting base 3
Insert a screw 63 into 3 and screw it into a screw hole 22b provided at the end of the foot 22 of the main body to temporarily fix both. These procedures may be modified appropriately.

The state after the concrete has been poured and the form 8 has been removed is as shown in FIG. 10 in the figure
Indicates a concrete portion, and among the other reference numerals, the portions having the same reference numerals as those in FIG. 1 indicate the same portions. The nail 62 for fixing the mounting base 3 is made of a soft material such as a plastic material and has a cavity 34 inside. It can be easily removed by twisting.

[0010]

Since the wiring box fixture according to the present invention is configured as described above, the height of the wiring box can be adjusted and rust is unlikely to occur.
