Further, an inner wall 10 is formed on the short side surface of the skeleton, that is, on the inner side of the side surface composed of the two columns 3, the upper beam 4 and the lower beam 6.

Outside the inner wall 10, that is, outside the upper beam 4 and the lower beam 6, a length corresponding to the height of the building unit 2, specifically, a length slightly longer than the height of the column 3. The wiring conduit 21 having a thickness is mounted via mounting brackets 30A and 30B. In addition, other building units 2
Except that the wiring unit 21 is not provided, the same framework, floor, and floor as the building unit 2 having the wiring unit 21 are used.
It is composed of a ceiling and the like. And the wiring conduit 2
Numeral 1 is made of elastic rubber and has an oblong cross section. At the lower end of the wiring conduit 21, a fitting portion 21A having an enlarged inner diameter is formed.

As shown in FIG. 4, the mounting bracket 30A includes a fixing piece 31 fixed to the upper beam 4 and a fixing piece 31.
Of the wiring conduit 21 between the fixing piece 31 and the holding piece 32, which is rotatably provided at one end of the
It is composed of The fixing piece 31 is provided with a fitting hole 31A which is engaged with the projection 34 at a position corresponding to the projection 34 protruding outside the upper beam 4, and a screw hole 31B at an end opposite to the hinge 33. ing. The holding piece 32 is provided with an insertion hole 32A for a bolt (not shown) screwed into the screw hole 31B of the fixing piece 31 at an end opposite to the hinge 33. Since the mounting bracket 30B is the same except for the lower beam 6, the description is omitted.

FIG. 5 shows upper and lower building units 2A and 2B.
2 shows a state in which the wiring conduit 21 attached to the wiring is connected. The upper end of the wiring conduit 21 of the lower-floor building unit 2B is located slightly higher than the upper beam 4,
The fitting unit 21A provided at the lower end of the wiring conduit 21 of the upper floor building unit 2A is fitted without any gap.

Next, a method of constructing the wiring structure will be described. Upper-floor building unit 2A corresponding to the upper and lower floors in advance
And the wiring conduit 21 on the side of the lower-floor building unit 2B.
Attach. At this time, as shown in FIG.
The fixing piece 3 of the mounting bracket 30 </ b> A is
The fitting holes 31A provided in the fitting 1 are fitted and fixed. Then, the holding piece 32 is rotated via the hinge 33 so that the wiring conduit 21 is held between the fixing piece 31 and the holding piece 32, and the bolt inserted from the insertion hole 32A is screwed into the screw hole 31B.
To fix the fixing piece 31 and the holding piece 32 together. The lower end of the wiring conduit 21 is fixed in the same manner. For transportation to the construction site, the wiring conduit 21 is bent, and the upper end of the wiring conduit 21 is substantially the same as the upper surfaces of the upper and lower floor building units 2A and 2B, as shown by the two-dot chain line in FIG. In this state, the upper and lower floor building units 2A and 2B are transported to the construction site.

At the construction site, the lower-floor building unit 2B
After the upper-floor building unit 2A is installed on the above, the wiring conduits 21 of the upper and lower-floor building units 2A and 2B are connected. At this time, the wiring conduit 21 of the lower-floor building unit 2B that is curved and attached is returned to its original straight state, and the wiring conduit of the lower-floor building unit 2B is fitted to the fitting portion 21A of the upper-floor building unit 2A. The upper end of 21 is fitted. Then, if the building units 2 on each floor are arranged as shown in FIG. 2, the wiring conduits 21 are arranged in gaps between the building units 2. In the wiring conduit 21 for wiring, wires such as televisions and telephones, which are weak wires, are passed.

According to the above-described embodiment, the following effects can be obtained. Since the wiring conduits 21 are provided on the side surface of the building unit 2 in the vertical direction of the building unit 2, there is no need to form an opening in the floor or ceiling and pass a shaft, and the floor of the building unit 2 can be used effectively. . This means that there is no need to form an opening in the floor or ceiling, and since the wiring conduit 21 is concealed by the inner wall 10 or the like, no puffing wall is required, and the productivity of the building unit 2 is secured. Can be.

Further, since the wiring conduit 21 is provided in the gap between the adjacent building units 2, the gap which is the dead space of the adjacent building unit 2 can be effectively used.

Further, the wiring conduit 21 is previously attached to the building unit 2 via the fittings 30A, 30B at the factory, and the upper and lower floor building units 2A,
After installing 2B, the upper end of the wiring conduit 21 of the lower floor building unit 2B may be fitted into the fitting portion 21A formed at the lower end of the wiring conduit 21 of the upper floor building unit 2A. Therefore, the connection work of the wiring conduit 21 at the construction site can be simplified. At this time, the wiring conduit 21
Is formed to a length slightly longer than the height of the building unit 2, and when transported to the construction site, the wiring conduit 21 is transported in a curved state. Workability on site can be improved.

Since the wiring conduit 21 is made of elastic rubber, the wiring conduit 21 is bent when transported to a construction site, and is bent according to the gap between the adjacent building units 2. Can be elastically deformed into a desired shape, so that the wiring conduit 21 can be smoothly inserted into the gap between the adjacent building units 2.

The mounting brackets 30A and 30B are
And the holding piece 32 rotatably provided via the hinge 33, so that the wiring conduit 21 is sandwiched between the fixing piece 31 and the holding piece 32. By simply connecting the fixing piece 31 and the holding piece 32 with bolts, the wiring conduit 21 can be easily inserted and fixed.

Since the cross section of the wiring conduit 21 is an ellipse, it does not rotate in the mounting brackets 30A and 30B even if it is sandwiched between the mounting brackets 30A and 30B.

As described above, the present invention has been described by way of preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications and changes in design can be made without departing from the gist of the present invention. Is possible. For example, the wiring conduit 21 is provided in a gap between the adjacent building units 2, but is not limited thereto, and may be the outer peripheral wall of the building body 13 as long as the side surface of the building unit 2.

Although the wiring conduit 21 is formed to have a length slightly longer than the height of the column 3, the present invention is not limited to this, and may be the same as or shorter than the height of the column 3.

The fitting portion 21 of the wiring conduit 21
A is not limited to the lower end of the wiring conduit 21, but may be formed at the upper end of the wiring conduit 21. At this time, if the connection is made in the same manner as the method described in the embodiment, the same effect can be obtained.

The material of the wiring conduit 21 is not limited to rubber, but may be resin or the like.

The cross section of the wiring conduit 21 is not limited to an ellipse but may be a circle. At that time, the wiring conduit 21 is
An engagement hole is provided at a position where it engages with the projection 34 of the upper beam 4 and the lower beam 6 because it turns inside the mounting brackets 30A and 30B. By doing so, the same effect as described in the embodiment can be obtained.
