A concrete frame F having a reverse beam structure, which forms a framework of the apartment house, extends in the horizontal direction and partitions the building into a plurality of upper and lower layers. And a vertical frame portion Fv extending vertically and interconnecting the upper and lower horizontal frame portions Fh.

The horizontal frame portion Fh has a reverse beam structure in which a plurality of reverse beams are integrally and vertically projecting upward and downward on the upper surface of the concrete slab S. The section inverted beam 1 surrounding the outer periphery of the living part of one house is formed in a square shape by connecting the pillars P at the four corners, and extends in parallel with each other at intervals and before and after the inverted beams 1a and 1b. And left and right inverted beams 1c and 1d extending in parallel with each other. The rectangular portion surrounded by the section inverted beam 1 defines an underfloor storage space LS for a single living room.
In order to bisect S, the floor slab S is formed with a main trunk reverse beam 2 which runs longitudinally in the center thereof and whose front and rear ends are connected to the front and rear reverse beams 1a and 1b. Reverse beam 2
A reinforcing inverted beam 3 is formed in the middle of the cross-section.

Between the left inverted beam 1c and the main inverted beam 2 and between the right inverted beam 1d and the inverted main beam 2, a plurality of large pulleys 4 are laid in parallel with each other. A plurality of joists 5 are mounted on the large joists 4 at right angles to each other in parallel with each other, and a flooring 6 is laid on the joists 5. The floor structure 7 is constituted by the joists 5 and the flooring 6. Above the floor structure 7, an on-floor space US serving as a living space is formed, and below the floor structure 7, the under-floor storage space LS is formed.

In the underfloor storage space LS, a strip-shaped facility trunk area MA is provided along one side of the trunk reverse beam 2 over the entire length thereof. In this equipment main line area MA, a water supply system main line 8M (shown by a white line) and a drainage system main line 9M (shown by a black line) are exposed substantially parallel to the main line reverse beam 2. These pipe trunk lines 8M and 9M penetrate the reinforcing reverse beam 3. The outer end of the water supply pipe trunk line 8M is frame F
And the outer end of the drainage pipe trunk line 9M is connected to a drainage passage 29 that extends vertically through the frame F and communicates with the sewerage system.

The water supply and drainage piping trunks 8M, 9
M is supported in a suspended state in the equipment main line area MA by the puller 4 constituting the floor structure 7 without contacting the slab S. Since the support structure of the water supply system pipe trunk 8M and the drainage system pipe trunk 9M is the same, the support structure of the water supply system pipe trunk 8M will be described below with reference to FIGS. Piping trunk line 8M
A plurality of large pulleys 4 are suspended and supported, and a support rod 12 is suspended and supported by a rubber packing 13 at each of the large pulleys 4 made of a beam material. The support rod 12 is a turnbuckle 14 in the middle thereof with hook-shaped support portion 12 ₁ is formed is connected to the lower end, it is possible that the length adjustment. A plurality of support members 12 of a plurality of support rods 12 arranged in a row at right angles to the plurality of pulleys 4.
₁ includes a rubber packing 1 for the main pipe 8M of the water supply pipe system.
It is removably supported via 6. As described above, the pipe main line 8M of the water supply pipe system is supported in a suspended state by the heavy lifting 4, so that the vibration of the pipe main line 8M itself and the noise generated from the water flowing therethrough are directly transmitted to the frame F. There is no transmission.

In the case of supporting the water supply and drainage pipe trunks 8M and 9M in parallel with the arrangement direction of the plurality of girders 4, as shown in FIG. during, a plurality of cross Obiki 4 ₁ connected with a connecting fitting 15, their cross Obiki 4 _1, a plurality of the support bars 12
And the supporting rods 12 removably support the water supply and drainage pipe trunks 8M and 9M.

As shown in FIG. 2, the pipe trunk 9M of the drainage system has a downward slope from the upstream side to the downstream side (exit). In this case, the underfloor storage space LS surrounded by the inverted beams can secure a depth of about 60 cm, so that the descending slope can be largely secured. As a result, drainage efficiency is greatly improved.

In the equipment main line area MA,
, Also supports wiring trunks such as electric wires.

In the underfloor storage space LS, an equipment area is set by selecting a desired position, and in this equipment area, equipment provided with appropriate piping, in this embodiment, a plumbing equipment WE is provided. In this plumbing system WE, as usual,
Rooms such as a bathroom 17, a dressing room 18, a toilet 19, and a kitchen room 20 are collectively arranged. In these rooms, plumbing equipment such as a bathtub, a washing machine, a toilet, and kitchen equipment is provided. The water supply and drainage pipe branch lines 8B and 9B connected to the equipment are connected to the water supply and drainage pipe trunk lines 8M and 8M.
9M is detachably connected via a joint 24. That is, a plurality of branch pipes 8'M, 9'M branched from water supply and drainage pipe trunks 8M, 9M, which are provided in the facility trunk area MA, penetrate the trunk reverse beam 2 and are provided with a water supply facility WE. And connected to the water supply and drainage piping branch lines 8B and 9B via the joint 24, respectively.

Thus, as shown by a chain line in FIGS. 1 and 2, the equipment area is set at another position, and the water supply equipment WE is placed there.
Is installed, and the water supply and drainage piping branch lines 8B and 9B
Can be detachably connected to the water supply and drainage piping trunk lines 8M and 9M in the same manner as described above. In this way, the plumbing equipment WE can be installed at a desired position in one living part.

The water supply and drainage pipe branch lines 8B,
Similarly to the water supply and drainage piping trunks 8M and 9M, the water supply and drainage piping main lines 8M and 9M can also be supported in a suspended state by the support bar 12 on the large scale 4.
Vibration and noise generated from B and 9B can be prevented from being directly transmitted to the skeleton F.

As described above, no matter where the underwater storage space is located, such as a water supply facility WE, it is possible to easily and easily connect the pipe branch line of the facility to the pipe trunk. Become.

The pipe trunks 8M and 9M are connected to the floor structure 7
Is suspended in a suspended state, and a gap is formed between itself and the frame F, so that vibrations and noise generated in the pipe trunk lines 8M and 9M are not directly transmitted to the frame F. Therefore, the propagation of vibration and noise to downstairs and the like can be reduced as much as possible.

FIG. 7 shows a water supply and drainage pipe main line,
Other modified examples of the supporting structure of the piping are shown.

In FIG. 7, an outline 4 of the floor structure 7 includes:
Support frame 3 assembled from angle materials via packing
0 is supported in a suspended state.
Water supply and drainage piping trunks 8M and 9M supported via rubber packing 31 and other pipings 34 and 3
5 and 36 are fixed to the support frame 30 by the inverted U-shaped stopper 32.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various embodiments are possible within the scope of the present invention.

For example, in the above-described embodiment, a case has been described in which the pipe mains for the water supply and drainage systems are provided in the equipment mains area. However, mains other than those pipes mains may be provided in the equipment mains area. .
