Therefore, it is difficult to easily construct various pipes and the like.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a module system in which the installation routes of various pipes extending under the floor and above the ceiling are completed in advance by a module system, and to facilitate the installation of these pipes.

[Means for Solving the Problems] The present invention according to claim 1, in a unit building constituted by combining a box-shaped unit in which a beam and a column are framed in a box shape, a horizontal structure of each box-shaped unit. Each box-shaped unit is composed of a central portion whose length in the direction is an integral multiple of the same reference length, and end portions each of which is (reference length-interval between box-shaped units) / 2. A pipe insertion hole drilling position having the reference length as a pitch interval is set in the longitudinal direction of the beam located at the central portion of the above, and a pipe insertion hole is drilled in at least one of the pipe insertion hole drilling positions. It is to become.

In the present invention according to claim 2, the reference length is three feet, 0.9
It is a divisor of general modules such as m and 0.91m.

According to the present invention, the length of the box-shaped unit and the position of the through-hole for drilling various pipes and the like set on the beams constituting the box-shaped unit are the same. It will be built with the system. Therefore, when the installation route of the water supply / drainage piping, air conditioning piping, telecommunications wiring, etc. extending in the box type unit is set in advance by the module system, the installation route is extended under the floor or above the ceiling according to the above installation route. The various pipes smoothly pass through the insertion holes drilled at the insertion hole drilling positions set in the module system without having to adjust the site. Therefore,
Arrangement routes of various pipes and the like extending under the floor or behind the ceiling are set in advance by the module system, and the pipes and the like can be easily constructed.

According to the present invention as set forth in claim 2, the reference length is 3 shaku, 0.
Since it is a divisor of common modules such as 9m and 0.91m, there is an advantage that commercially available products can be used as piping components as they are.

[Example] FIG. 1 is a cross-sectional view showing a main part of a unit building to which the present invention is applied, FIG. 2 is a side view showing a piping state of the unit building, FIG. 3 is a schematic plan view of FIG. 4 is a front view showing a small beam, FIG. 5 is an enlarged view of a main part of FIG. 2, FIG. 6 is a side view of FIG. 5, and FIG. 7 is a perspective view showing a box-shaped unit.

The unit building 1 shown in FIG. 1 is constructed by arranging the box-shaped unit 10 shown in FIG. 7 horizontally and vertically on a foundation laid in advance at a building site.

The box-shaped unit 10 is formed by framing each of four mold steel floor girders 12, steel pipe columns 13, and steel girders 14 into a box shape, forming a floor structure with the floor girders 12, and using the ceiling girders 14. Form a ceiling structure.

That is, as shown in FIGS. 1 and 7, the floor structure is composed of an ALC floor base plate 15 connected to the floor girders 12, a plywood gilt 16, a floor joist 17, and a floor plate laminated sequentially on the floor base plate 15. It is composed of 18.

Also, as shown in FIGS. 1 and 7, the ceiling structure is a steel beam ceiling beam 19 connected to the ceiling beam 14, a field support 20 fixed by the ceiling beam 19, and a field support 20. It comprises a ridge 21 fixed to 20 and a ceiling board 22 fixed to the ridge 21.

 In FIG. 1, 23 is an inner wall, and 24 is an outer wall.

At this time, in the box-type unit 10, as shown in FIG. 7, the pillar 13 is provided on the four laps of the area b _1, b _2. The intervals in the areas b ₁ and b ₂ including the columns 13 are integer multiples of the reference length l _{1 in} the long side direction and integer multiples of the reference length l _{2 in} the short side direction. Here, the lengths of the reference length l ₁ and the reference length l ₂ are set to be equal, and l ₁ = l ₂ = a.

The reference length a is a common module of 3 shaku, 0.9 m, 0.
It is a divisor such as 91m.

If the widths b ₁ and b ₂ of the area b of the four peripheral portions are set to a size that can accommodate the column 13 and the like, and the distance between adjacent box-shaped units is d, b ₁ = b ₂ = (a −d) Set to / 2. The interval d is provided between adjacent units for absorbing dimensional errors of the units, for connection, and the like, and is usually set in a range of about 0 to 30 mm.

Since the reference lengths l ₁ and l ₂ and the widths b ₁ and b ₂ of the four peripheral portions are set as described above, the length L ₁ ,
The short side direction of the length L ₂ is m, respectively long side of n, as the number of modules of the short _{side, L 1 = ml 1 + 2b} 1 = ma + 2 · (a-d) / 2 = (m + 1) a-d L 2 _{= nl 2 + 2b 2 = na} + 2 · (a-d) / 2 = (n + 1) becomes a-d.

That is, in the unit building to which the present invention is applied, the long side and the short side of each box-shaped unit are each designed to be equal to the length obtained by subtracting the length of the interval between the box-shaped units from an integral multiple of the same reference length. Since the same length as the reference length of (ad) / 2 + d + (ad) / 2 = a occurs at the joint between the box units, a number of the box units were connected. Even in this case, the design can be performed without breaking the module.

In addition, since the reference length is a divisor of a common module such as 3 shaku, 0.9m, 0.91m, etc., general modules can be divided for frontage, layout, etc., and commercially available products can be used.

However, in the present invention, each of the above box-type units 10
As shown in FIGS. 1, 4, and 7, in the longitudinal direction of each of the floor girder 12, the ceiling girder 14, and the ceiling girder 19, the through holes having the reference length a as a pitch interval are formed. Set the installation position,
Insertion holes 31 are formed at these insertion hole formation positions.

The insertion hole 31 serves as an insertion path for water supply / drainage piping, air conditioning piping, electric communication wiring, and the like disposed below the floor and behind the ceiling.

2 and 3 show the insertion hole 31 provided in the ceiling beam 19.
In this example, an air conditioning pipe 32 is inserted.

In the embodiment of the present invention, each box-shaped unit 10
Arrangement routes for water supply / drainage pipes, air-conditioning pipes, electric communication wirings, and the like extending inside the box-shaped unit 10 are set by a module system divided into modules by the reference length a.

 Next, the operation of the above embodiment will be described.

According to the above-described embodiment, the length of the box-shaped unit 10 and the insertion holes for various pipes and the like set in the beams of the floor girders 12, the ceiling girders 14, and the ceiling beams 19 constituting the box-shaped unit 10. The drilling position is constructed by the same module system. Therefore, when the installation routes of the water supply / drainage pipes, air conditioning pipes, telecommunications wiring, etc., extending in the box-shaped unit 10 are set in advance by the module system, the installation routes are extended under the floor or above the ceiling in accordance with the above-described installation routes. The various pipes smoothly pass through the insertion holes 31 drilled at the insertion hole drilling positions set by the module system, without having to adjust the site. Therefore, the installation routes of various pipes and the like extending under the floor or behind the ceiling are set in advance by the module system, and the pipes and the like can be easily constructed.

In addition, the standard length for constructing the module system is 3
Since it is set to be a divisor of a general module such as 9 m or 0.91 m, there is an advantage that a commercially available product can be used as it is as a component of piping.

In the practice of the present invention, insertion holes may be provided in advance in a factory or the like at all of the insertion hole drilling positions set at the above-mentioned pitch intervals in the longitudinal direction of the beam. Of these, the insertion hole may be provided only at a position compatible with the piping schedule of the unit.

[Effects of the Invention] As described above, according to the present invention, the installation routes of various pipes and the like extending below the floor or behind the ceiling are set in advance in the module system, and the pipes and the like can be easily constructed.
