Description

[Detailed description of the invention] [Industrial application field] The invention relates to a wiring duct.

[Conventional technology]

As a duct used to wire wires such as electric wires,
2. Description of the Related Art Conventionally, as described below, there is a wiring duct including a duct main body and an accessory connected to the duct main body. The attachment includes, for example, a coupling. The duct main body 71 includes a gutter-shaped main body base 80 and a cover 81, as shown in FIG. 4, and the coupling 72 includes an attached base 90 and a cover 91, as shown in FIG. Body base 80
At the center of the bottom portion 80a, two round holes 82 for mounting are formed along the longitudinal direction. On the other hand, in the center of the bottom 90a of the attached base 90, one round hole 92 for attachment is clear. And
As shown in Fig. 5, the attached base 90
The two contact pieces 90c, 90c are provided on the side facing 80, and when both bases 80, 90 are connected, as shown in FIG. 6 (c), the contact piece 90c is attached to the bottom of the main body base 80. Overlaps and contacts 80a.

 Construction of this wiring duct is performed in the following procedure.

Perform ink summit. That is, as shown in FIG. 6A, a reference line A is drawn on the mounting surface. The longitudinal center of the wiring duct is located at the reference line A.

Pull the wires out of the ceiling or wall.

As shown in FIG. 6A, the center position of the attached base 90 on the reference line A is indexed and a mark B is attached. Separate the attached base 90 from the cover 91 and connect the attached base 90 to the reference line A.
And a mark B is made in the middle of the hole 92.

The dimension L of the duct body 71 between the couplings 72 is determined. The dimension 1 between the marks B and B and the occupied length l 'of the attached base 90 are measured, and a calculation for determining the dimension L (l-2l' = L) is performed.

Using a metal saw, the duct body 71 is cut to the length L.

The position of the leading edge of the main body base 80 is determined. As shown in FIG. 6 (b), the position where the exclusive length l 'of the attached base 90 is away from the mark B is measured and the mark C is attached.

The main body base 80 and the cover 81 are separated, and as shown in FIG. 6C, the main body base 80 is first fixed through the holes 82 with screws 89.

As shown in FIG. 6 (c), the attached base 90 is fixed between the main body base 80 with the screw 99 through the hole 92.

The electric wire is placed (placed) inside the main body base 80 and the attached base 90.

The cover 81 is put on the main body base 80.

The cover 91 is put on the attached base 90.

 This completes the construction.

[Problems to be solved by the invention]

However, in the case of the above-mentioned wiring duct, it takes time and effort to construct, and the accuracy of the length and the mounting position of the duct main body cannot be said to be sufficient.

The reason for the troublesome work is that the work of measuring the exclusive length l 'of the attached base 90 and the work of measuring the tip position of the main body base 80 are quite troublesome.

The reason why the accuracy of the length and the mounting position of the duct body is not sufficient is that the accuracy of the length and the mounting position of the duct body is the exclusive length l 'of the attached base 90 which is the basis for determining the same length and the mounting position. This is because the measurement accuracy depends on the measurement accuracy and the measurement accuracy for determining the position of the tip of the main body base 80, and the measurement accuracy may be insufficient such as when an unskilled worker performs the measurement work.

In view of the above circumstances, it is an object of the present invention to provide a wiring duct that can quickly perform construction with high accuracy in the length and mounting position of a duct main body.

[Means for solving the problem]

In order to solve the above problems, in the wiring duct of the present invention, a gutter-shaped main body base, an attached base connected to the gutter-shaped main body base, a cover put on the gutter-shaped main body base, and a cover put on the same attached base are provided. In the wiring duct, wherein the attachment base has a contact piece overlapping with and contacting the bottom of the gutter-shaped main body base on a side facing the gutter-shaped main body base, the contact piece of the attached base has a center mark. And a hole for writing a mark is provided at a position overlapping the edge of the gutter-shaped main body base.

In the case of the wiring duct of the present invention, for example, the wiring duct is formed using a metal material, but is not limited thereto, and may be formed of another material.

Examples of the center mark on the contact piece of the attached base include a mark formed by a cut or a protrusion formed at the center of the edge of the contact piece, but the present invention is not limited to this, and may be a print mark.

Examples of the hole for writing a mark include a long hole and a slit-like hole that looks like a groove.

Examples of the attachment include a coupling, a switch box, and a corner box.

[Action]

In the case of the wiring duct of the present invention, it can be constructed more quickly than before.

In the case of the wiring duct of the present invention, when determining the length of the duct body at the time of construction, the dimensioning work for finding the exclusive length l ′ of the attached base and the gutter-shaped body base (hereinafter simply referred to as “body base”) This is because there is no need for a measuring operation to determine the tip position. That is, in the case of the wiring duct of the present invention, as shown in FIG. 3B, the attached base 20 is placed with the center mark 23 coincident with the reference line A and the mark C is placed in the hole 24 for filling the mark. Then, as shown in FIG. 3 (d), the duct main body is cut between the marks C, C according to the length (for example, by marking them with actual goods) as shown in FIG. 3 (d). Then, as shown in FIG. 3 (e), the main body base 10 is fixed with its leading edge aligned with the position of the mark C. In this way, no measuring work is required.

In addition, the accuracy of the length and mounting position of the duct body is sufficient.

This is because the length of the duct body and the mark C, which is the basis for positioning, can be accurately and easily determined according to the actual product as described above. Even inexperienced workers can perform work as inferior to skilled workers.
