2. Description of the Related Art In recent years, due to the shortage of land in large cities and the exhaustion of the required number of houses, in urban apartments, for example, middle to high-rise apartments of 10 to 15 floors have been constructed. It's coming. These are generally H
The SRC structure is mainly made of shaped steel, the beam is a large PC board with the steel beam and the wall part integrated, the boundary wall is a PC board with beam braces, and the floor is cast on-site. The building construction technology was applied.

By the way, even in this type of apartment house,
Prefabricated houses such as detached houses have been developed in order to reduce time, materials and labor costs and to obtain high quality houses. A unitized construction method is known as one of the prefabrication methods. This unitized construction method is a method of stacking steel-framed rectangular box-shaped dwelling unit units on-site by a crane, and is also called a block construction method. As for the outer wall of the dwelling unit, a curtain wall made of steel resistant steel plate is attached in advance at the factory, and sash and glass are also attached at the factory.

[0004]

By the way, in the above-mentioned unitization method, if the interior of the unit is pre-installed in the factory, the construction at the site can be simplified and the quality of the interior can be standardized. You can However, for air-conditioning pipes (including ventilation) that need to be installed continuously across multiple dwelling unit units, at least the connection between dwelling unit units must rely on field work. I didn't get it.

Since the air-conditioning pipe is provided inside the interior (behind the ceiling, etc.), the interior of the portion for connecting the pipe must be installed on-site.
Therefore, such a pipe connecting work has been a hindrance in increasing the ratio of work in a factory in order to simplify the construction on site in a building including a dwelling unit. Further, there is a possibility that dew condensation may occur in the air conditioning pipe, and it is necessary to cover the heat insulating material at the site of the connection of the dwelling unit, which makes the joining of the dwelling unit complicated. ..

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to facilitate the work of connecting pipes between dwelling unit units so that the construction site of the dwelling unit is constructed. An object of the present invention is to provide a connection structure for air-conditioning pipes, which can simplify the construction in.

[0007]

In the connection structure for air conditioning pipes according to the present invention, the air conditioning pipes are installed in advance in factories or the like in each dwelling unit unit, and adjacent dwelling unit units have respective wall surfaces spaced from each other. The connection portions of the air-conditioning pipe end portions are arranged to face each other and the connection portions of the air-conditioning pipe end portions penetrate the wall surface of the dwelling unit from the inside to the outside of the dwelling unit, and the wall surfaces of the dwelling unit are connected to each other. Are arranged so as to abut each other, and ring-shaped packings are respectively provided on the wall surfaces facing each other so as to surround the periphery of the connection parts, and the tip surfaces of these ring-shaped packings are The means for solving the above problem is that the ring-shaped packings are in contact with each other so as to seal the inside.

[0008]

According to the present invention, when constructing a building composed of dwelling unit units, the connecting portion of the air conditioning pipe is abutted at the stage where adjacent dwelling unit units are arranged at predetermined positions, and the portion is It is designed to be covered by ring-shaped packing. Therefore, only by installing the dwelling unit, the connection of the air conditioning pipe between the adjacent dwelling units is completed. At this time, cold air or the like inside the pipe is doubly sealed by the abutting connection portion and the packing surrounding the periphery, and there is no possibility of leaking to the outside from the connection portion of the dwelling unit.

The structure of the dwelling unit 10 is not limited to the illustrated example, but can be variously changed according to the design requirements of the building to be constructed.

Next, the connection structure of the air conditioning pipe 1 in the above building will be described. The air conditioning pipe 1
It is a pipe having heat insulation and flexibility, and is formed in a bellows shape. As shown in FIG. 3 and the like, this air conditioning pipe 1 is provided under the ceiling of each dwelling unit 10, 20, that is,
The dwelling unit 10, 20 is arranged at the height of the upper beams 10b, 22 of the unit. And each dwelling unit 10,
20 is sent from the factory to the site with the ceiling provided under the pipe. That is, the dwelling unit 10, 20 is
The air-conditioning pipe 1 is installed, the ventilation port 6 and the like are installed, and the interior of the ceiling and the like is further provided so that the air can be sent from the factory to the site.

The air-conditioning pipe 1 connected to the dwelling unit 10 or 20 is connected to the end of the air-conditioning pipe 1 of the adjacent dwelling unit 10 or 20 when the end is not the end of the pipe arranged on each floor. It will be joined. The air conditioning pipe 1
At the end of the pipe, a connecting portion 2 on the pipe is provided.
Is inserted into the through hole 4 provided in the channel-shaped steel material forming the upper beams 10b and 22 of the housing units 10 and 20. The tip of the connecting portion 2 has upper beams 10b, 22
The upper beams 10b and 22 are fitted in the through holes 4 in a state of protruding to the outer surface side. The length of the protruding portion of the connecting portion 2 is the same as that of the upper beam 2 of the dwelling unit 10 or 20 adjacent to each other.
It is formed longer than half the length of the interval between the two (10b). Further, the peripheries of the through-holes 4 of the upper beams 10b and 22 are flared so as to project to the inside of the unit. The flare 5 strengthens the steel material provided with the through-holes 4 and the air conditioning. It is designed to guide the end of the pipe 1 for use.

The air conditioning pipe 1, the connecting portion 2 and the upper beam 2
The connection of 2 (10b) is such that one end of the connection portion 1 is fitted inside the end portion of the air conditioning pipe 1 and the upper beam 22 (10b).
The flare 5 is sandwiched between the inner surface of the air conditioning pipe 1 and the outer surface of the connecting portion 2.

A ring-shaped packing 3 is adhered to the outer surface of the upper beam 22 (10b) so as to surround the tip of the connecting portion protruding from the upper beam 22 (10b). The thickness of the packing 3 is such that the dwelling unit units 10 and 20 adjacent to each other are
The upper beams 22 (10b) are formed to be slightly thicker than half the distance between them. Also, this packing 3
Is made of a resin having elasticity, for example, natural rubber, rigid rubber, or other resin. Also, the connection part 2
Is slightly thicker than the packing 3, and is made of a resin having elasticity, for example, natural rubber, rigid rubber, or other resin.

When the dwelling unit units 10 and 20 are installed, the through holes 4 provided in the upper beams 22 (10b) of the dwelling unit units 10 and 20 that are adjacent to each other overlap each other. It is like this. That is, the connecting portion 2 fitted in each through hole 4 is
The tips are arranged to face each other. The connecting portion 2 is adapted to abut on the tip end surfaces 2a of the connecting portion 2 in a state of communicating with each other.

The packings 3 adhered to the opposing upper beams 22 (10b) are also overlapped. Since the thickness of the connecting portion 2 and the packing 3 is thicker than half the distance between the upper beams 22 (10b), the tip surfaces 2a and 3a of the connecting portion 2 and the packing 3 contact each other in a pressed state. I have come into contact with them. Therefore, the interiors of the connecting portion 2 and the packing 3 that abut the tip surfaces 2a and 3a are in a sealed state. Therefore, even if cool air or the like leaks from the connecting portion between the connecting portions 2 of the air conditioning pipe 1, the packing 3 prevents the cool air from leaking into the gap between the units, and prevents wasteful use of the cooling air. can do.

The air conditioning system in this embodiment is
An air conditioner (not shown) provided on the top floor performs heating / cooling and ventilation of each dwelling unit. The air conditioning pipe 1 is branched from a main air conditioning pipe (not shown) and provided horizontally on each floor. Further, the main pipes are arranged in a line along the top and bottom of the reinforced dwelling unit unit 20. This is because in order to effectively use the space of the building, a part of the reinforced dwelling unit 20 in which it is difficult to provide many openings for strengthening rigidity is used as a piping space that does not require openings such as windows. Is.

Next, a method of connecting the air conditioning pipes 2 when the dwelling unit units 10 and 20 are connected on site to construct a building will be described. To build a building, reinforced dwelling unit 2
0 and the dwelling unit 10 are installed with air conditioning pipes and are manufactured in an interior state, and these are transported to the site by a truck or the like, and the dwelling unit 1 is installed from the first floor.
Four 0s and 20s are arranged vertically and horizontally.

The arrangement of these units 10 and 20 is
The reinforced dwelling unit units 20 are installed so as to be located at the four corners of the building, and the dwelling unit units 10 are arranged between these reinforced dwelling unit units 20.

Then, the reinforced dwelling unit 20 and the dwelling unit 10 are successively stacked on the reinforced dwelling unit 20 and the dwelling unit 10 by a crane, and the units adjacent to each other in the front, rear, left and right are fastened. At this time, the through holes of the upper beams 10b and 22 of the adjacent dwelling unit units 10 and 20 overlap, and the packing 3 having elasticity of the upper beams 10b and 22 and the tip surfaces 3 and 2a of the connection portion 2 are provided. Are in contact with each other. Although the total thickness of the two packings 3 is slightly longer than the distance between the upper beams 10b and 22 facing each other, the packing 3
Has elasticity, the tip end surface 3a is in a state of abutting in a slightly compressed state. Further, the tip end surfaces 2a of the connection portions 2 are also in contact with each other, and the connection of the air conditioning pipe 1 is completed at the stage when the adjacent dwelling unit units 10 and 20 are connected.

As described above, the air conditioning pipe 1 of this embodiment
According to the connection structure of, the adjacent dwelling unit units 10, 20
Just by installing the air-conditioning pipe 1, the connecting portion 2 of the air-conditioning pipe 1 is brought into contact with the tip end surface 2a at a position where it is surrounded by packing 3, that is, the connecting portion of the air-conditioning pipe 1 is Since it is in a sealed state, cold air, etc. does not leak from the connection part. Further, since the connecting portion of the air conditioning pipe 1 is sealed by the ring-shaped packing 3, it is possible to prevent the occurrence of dew condensation, and even if dew condensation should occur, the dew condensation water will be generated between the dwelling unit units. It does not leak into the gap at the joint part of. The shapes and dimensions of each component shown in the examples are examples, and can be variously changed based on the design requirements of the building to be applied,
For example, in the above embodiment, the connecting portion 2 of the air conditioning pipe 1
Is configured to penetrate the upper beam 22 (10b) made of a channel-shaped steel material, but it is not limited to the upper beams 10b and 23 and may be any wall surface portion of the dwelling unit 10, 20. Also,
The shapes of the upper beams 10b and 23 are not limited to the channel shape, and may be H-shaped steel, square steel pipe, or the like.

Further, in the embodiment shown in FIGS. 4 to 6,
