BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. In FIG. 4 and FIG. 5, the wiring box 1 is attached to the back surface of the wall material 21, and wiring equipment and the like are housed inside. The opening surface of the wiring box 1 is an opening formed in the wall material 21. Faces the wall surface. At the eccentric position of the bottom wall 2 of the wiring box 1, a detected part 3 is integrally provided upright. The detected portion 3 has a magnet 5 attached to the top end of a tubular body 4, and the tubular body 4
Can be broken off from the bottom wall 2 at an annular thin portion 2a formed on the bottom wall 2. Also, wiring box 1
A pair of boss bodies 6 for mounting a wiring device mounting frame (not shown) are formed on the upper and lower end portions of the inner surface facing each other.
The wall material 21 is formed of a plywood board, a gypsum board, a calcium silicate board, or the like.

On the other hand, in FIG. 1 to FIG.
Is formed in a size such that the main body 12 made of synthetic resin can be gripped, and the outer diameter of the hard steel wire or the like capable of forming the wall member 21 on one side surface of the main body 12 is 1.5 to 2.0 mm. A center drill 13 is provided so as to project. Further, the main body 12 is provided with an accommodating portion 15 for accommodating the metal rod 14, and the accommodating portion 15 is covered with a lid member 16 which can be opened and closed with a shaft portion 16a as a fulcrum. The metal rod 14 has a diameter of 1.2 mm
The magnetic metal rod is bent to form a hook shape.

Next, a method of confirming the position of the detected portion of the wiring box by using the opening tool 11 and the metal rod 14 of the present embodiment configured as described above will be described. Before confirming the position of the detected portion 3 of the wiring box 1 by magnetic detection in advance, before making a hole in the wall material 21 so as to expose the opening of the wiring box 1 installed on the back of the wall to the wall surface, first, In FIG. 5, the detected portion 3 of the wiring box 1 attached to the back of the wall using a known magnetic detector 31.
Detect the location of. When the magnetism detector 31 detects the magnet 5 of the detected portion 3 while moving the magnetometer 31 along the wall surface, the magnetometer 31 is lit and displayed, so that the position is marked.

Next, as shown in FIGS. 6 and 7, the small hole 2 is formed in the wall member 21 at the position marked by using the opening tool 11.
2 is drilled. At this time, since the center drill of the perforation tool 11 is formed of hard steel wire or the like, by holding the perforation tool 11 and pushing it while rotating left and right, a wall material made of a plywood board, a gypsum board, or the like. 21 can be easily drilled. When the wall material 21 is bored in this manner, the small holes 22 are formed to have a hole diameter of about 1.5 to 2.0 mm.

Next, referring to FIG. 8, the metal rod 14 is inserted into the small hole 22 from the wall surface. At this time, the detected part 3 and the small hole 22
If the position of the metal rod 14 is the same as the position of
Since it is attracted by the magnetic force of the magnet 5 of the
Can be confirmed to exist at a position facing the small hole 22. Here, although the metal rod 14 has a small diameter, the presence or absence of magnetic attraction can be sensed by the feel of the fingertip. On the other hand, if the detected portion 3 and the small hole 22 are displaced and apart from each other, the small hole 22 is formed from the wall surface because the magnet 5 is not magnetically attracted when the metal rod 14 is inserted into the small hole 22. It can be confirmed that the position is out of the detected part 3.

Here, when the wall member 21 is being drilled with the opening tool 11, it can be confirmed that an object is present if it hits various members on the back of the wall, but the object is the magnet 5. Since it can be confirmed whether or not there is a magnetic member such as the metal rod 14, the metal rod 14 is useful in that respect.

Next, after the position of the detected portion 3 is confirmed in this way, first, the punching tool 3 shown in FIG.
The center axes 33 of the two are aligned, and the first through hole 23 shown in FIG. 10 for exposing the opening surface of the wiring box 1 to the wall surface is formed by the perforating blade 34 with this position as the center of the perforation. Then, as shown in FIG. 10, the center shaft 3 of the punch 32 is
3 is aligned with the lower boss body 6, and the perforation center position 36 of the second through hole is displayed on the wall member 21 by the index displayed on the upper end of the cover body 35 of the perforation tool 32. Next, in FIG. 11, the center axis 33 of the perforation tool 32 is aligned with the center position 36 of the perforation of the second through hole, and the second through hole is bored with the perforating blade 34. Then, after forming a daruma-shaped through hole by the first through hole 23 and the second through hole in the wall material 21, the detected portion 3 of the wiring box 1 is broken off from the wall surface in FIG. . With the above, the work of exposing the opening surface of the wiring box 1 to the wall surface is completed.

By the way, a small hole 22 for confirming the position is formed in the wall member 21 before the through hole is formed. However, if the detection positions are the same, the first through hole 23 is formed. The small holes 22 are not left in the wall material 21 by being removed together with the waste material cut off at the time of drilling. On the other hand, when the small hole 22 is drilled but the detected portion 3 does not exist at that position due to a detection error, the wall material 21 is separated from the mounting position of the wiring box 1 even after the through hole is drilled. The small holes 22 may remain. However, since the small hole 22 has an extremely small diameter compared to the size of the through hole, even if it remains on the wall material 21, it does not cause any trouble in appearance, and even if it is defective in appearance, it can be easily performed. It can be repaired.

If the hole diameter of the small hole 22 is made smaller than that of the center shaft 33, the center shaft 33 is positioned within the small hole 22 even if the small hole 22 is positioned and the center shaft 33 of the punch 32 is aligned therewith. It does not move and the drilling center position is displaced, and therefore, there is no obstacle in positioning the center shaft 33.

Furthermore, since the end portion of the metal rod 14 is bent in a hook shape, it is possible to prevent the metal rod 14 from being accidentally dropped to the back of the wall when it is inserted into the small hole 22. It should be noted that the portion of the metal rod 14 bent into a hook shape to be inserted into the small hole 22 is, of course, required to be formed longer than the wall thickness.

As described above, according to the method for confirming the installation position of the wiring box of the present embodiment, the through hole is formed in the wall member 21 so that the opening of the wiring box 1 installed on the back side of the wall faces the wall surface. Previously, the detected portion 3 provided in the wiring box 1
After magnetically detecting from the wall surface, a small hole 22 is provided at a detection position of the detected portion 3 in the wall material 21, and then the metal rod 14 is inserted into the small hole 22 to detect the detected portion 3 The position of the detected part 3 is confirmed by the presence or absence of magnetic attraction.

Therefore, since the position of the wiring box 1 can be confirmed in advance when the through hole is formed in the wall member 21, the opening of the wall member 21 is formed at an accurate position corresponding to the wiring box 1. it can. Further, since the small hole 22 has an extremely small diameter, even if the small hole 22 remains in the wall hole 21 due to a detection error, it does not cause any trouble in appearance, and even if the appearance is defective, it can be easily repaired. it can.
When the through hole is formed by using the perforation tool 32 after the small hole 22 is formed, even if the center shaft 33 of the perforation tool 32 is aligned with the small hole 22 as the positioning, the center shaft 33 is positioned. There is no obstacle.

By the way, in the hole forming tool 11 of the above embodiment, the accommodating portion 15 for the metal rod 14 is formed, but since it is formed for the convenience of carrying and storing, the accommodating portion 15 is formed.
Is not necessarily required. Further, although the metal rod 14 has its end bent in a hook shape, the small hole 2 is detected in the magnetic detection.
If it can be prevented from being accidentally dropped to the back of the wall when it is inserted into the inside, it can have an arbitrary shape, for example, the end portion can be bent in an annular shape.

Further, in the above embodiment, the wiring box 1
The case where the center of perforation is found by detecting the detected part 3 of FIG. 13 is shown in FIG. 13 or FIG.
When the outer shape of the wiring box 1 as shown in FIG. 4 is extracted and cut with a saw or a cutter, the installation position of the wiring box 1 can be confirmed from the wall surface in the same manner. The wiring box 1 shown in FIG. 13 is provided with a pair of detection parts 3 having magnets 5 attached to the outer surfaces of the upper and lower side walls 7, and a magnetic detector having detection parts at two upper and lower positions is used. The outer shape of the wiring box 1 can be extracted. In the wiring box 1 shown in FIG. 14, a separate detected member 8 having a magnet 5 attached to the center thereof is held by a pair of upper and lower boss bodies 6 of the wiring box 1 at its gripping portion 8a. The outer shape of the wiring box 1 can be extracted by the central magnet 5. Here, the detected member 8 corresponds to the detected portion in each claim.

In the above embodiment, the case where the detected portion 3 and the detected member 8 to which the magnet 5 is attached is detected by the magnetic detector is shown. However, the present invention is not limited to this. The same can be applied to the case of detecting by metal detection or the like. In this case, wiring box 1
The metal rod 14 for checking the presence / absence of the detected part is equipped with a magnet.

Although all the above-mentioned embodiments relate to the wiring box, the object of the present invention is to be applied to the back of the wall, and the entire surface of the wiring box is provided, for example, through a through hole formed in the wall material. The present invention can be applied to not only the wiring box but also a piping box such as a hot and cold water supply pipe and a gas pipe in addition to the wiring box.
