BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure of a building. In particular, the present invention relates to a building piping structure suitable for a unit building.

[0002]

2. Description of the Related Art Conventionally, housing facilities such as a bath and a sink have often been provided on the first floor of a building, but recently, they are often provided on the second floor. When installing the housing equipment on the second floor like this, the drain pipe connected to this housing equipment
When passing through the building on the first floor, the living space of the building becomes narrower, and the sound of the drainage flowing in this drain pipe is annoying, so install the housing equipment along the inside of the outer wall and install it in this housing equipment. The connected drain pipe penetrates the outer wall and hangs downward along the outside of the outer wall to connect to the external drain pipe. On the other hand, recently, since the residential area is small, a garage space is often provided in the building.

The unit building is Japanese Patent Publication Sho 62-622.
As described in Japanese Unexamined Patent Publication No. 24, a box-shaped building unit having a certain size that can be transported and having an internal and external finished building unit is manufactured in advance in a factory, transported to a construction site, and then transported to a construction site. It is assembled into a building. This unit building is gradually and widely adopted because it has a characteristic that it is a standardized building with a short field construction period and good dimensional accuracy. This building unit is disclosed in JP-A-55-3
As described in Japanese Patent Publication No. 9549 and Japanese Patent Laid-Open No. 56-69048, four pillars arranged at the four corners of a rectangular space composed of short sides and long sides, and the upper portions of these four pillars are set to the short sides. Has a skeleton composed of four ceiling beams connecting along the long sides and four floor beams connecting the lower portions of these four columns along the short sides and the long sides.

Also in this unit building, when housing equipment is installed on the second floor, it has the same structure as the above building. That is, the housing equipment is attached along the inside of the outer wall, and the drain pipe connected to the housing equipment is connected to the outside drain pipe by penetrating the outer wall and hanging downward along the outside of the outer wall. In addition, even in a unit building, a garage space is often provided in the building.

When this garage space is provided, it has the following structure. That is, in order to produce a garage unit at a factory and transport it to a construction site, the length of the short side is made substantially equal to or shorter than the lateral width of the carrier. Therefore, since it is difficult for a vehicle to enter the garage unit with only one garage unit and the garage unit does not become a garage unit, a plurality of garage units are installed side by side on the foundation so that the short sides are on a substantially straight line, and are equivalent to the long sides of a rectangle. The floor beam is not provided on the side surface, and the garage space is formed by using this side surface as a communication opening of the garage unit. When the drainage pipe connected to the housing equipment is hung downward along the outside of the outer wall, the drainage pipe is exposed to wind and rain, and is therefore easily corroded. Therefore, the drain pipe is usually covered with a cover.

[0006]

However, if a cover is provided on the drain pipe hanging down along the outside of the outer wall, rainwater will enter the inside of the cover and the drain pipe will corrode, so that water will not enter. It is necessary to attach the cover in a watertight manner so that there is no such problem. In addition, the cover that covers the drain pipe hanging down along the outer wall of this building is unsightly because it protrudes from the outer wall and is unsightly, and when installing or repairing the drain pipe, work is done outdoors. hard. In particular, there is a problem that it is difficult to work when it is raining or snowing or when wind is strong.

In the unit building, the garage unit, which is the garage space, has no floor beam on the side surface corresponding to the long side of the rectangle, so that the base of the pillar is insufficiently fixed against the force from the short side direction. There is a problem that it is easy to fall down, and it is difficult to fix the pillar when transporting the garage unit. Therefore,
An object of the present invention is to provide a piping structure for a building which does not hang down the drainage pipe along the outside of the outer wall, and which has a good soundproof property and is easy to install and repair. Another object of the present invention is to provide a garage unit which has a large strength against a force from the short side direction and which can firmly fix a pillar during transportation, and a building in which the garage unit and a building unit are assembled. It is an object of the present invention to provide a piping structure for a building which is easy to install and repair, when the housing equipment is provided on the second floor without causing the drainage pipe connected to the housing equipment to hang down along the outside of the outer wall.

[0008]

The present invention has been made to achieve the above object, and the invention according to claim 1 is such that a garage space is provided on the first floor of a building, and the garage space is above the garage space. Housing equipment is provided in a room on the second floor or a room adjacent to the room on the second floor, and a drainage pipe attached to this housing equipment is hung from the room for housing equipment along the side wall of the garage space. It is a thing. In the present invention, the drainage pipe is hung down from the room of the housing equipment along the side wall of the garage space, but in order to do so, the floor of the room of the housing equipment is penetrated to form the side wall of the garage space. There is a means for hanging along the side wall of the garage space, and a means for penetrating the floor of the adjacent room from the room of the housing equipment through the adjacent room.

The invention according to claim 2 is characterized in that four pillars are arranged at the four corners of a rectangular space consisting of short sides and long sides, and the upper portions of these four pillars are arranged along the short sides and the long sides. 4 ceiling beams to be connected together and the lower parts of these 4 columns are connected along the short sides 2
A garage unit having a skeleton consisting of four floor beams and four floor beam pieces protruding along the long sides from the bottoms of the four pillars, so that the short sides of the garage unit are almost in a straight line,
A plurality of them are placed side by side and installed on the foundation, floor beam pieces are fixed to the foundation to form a garage space, next to or above this garage unit, at the four corners of a rectangular space consisting of short sides and long sides. Connected four pillars, four ceiling beams connecting the tops of these four pillars along the short and long pieces, and the bottoms of these four pillars along the short and long sides A building in which a plurality of building units each having a skeleton composed of four floor beams are installed, and the house is located in a room of a building unit on the second floor above the garage unit or a room adjacent to the room on the second floor. Equipment is provided, and a drainage pipe attached to the housing equipment is hung from a room of the housing equipment along a side wall near a corner of a garage space or a floor beam piece.

The invention according to claim 3 is the piping structure of a building according to claim 1 or 2, wherein a cover is detachably attached to a drain pipe attached along a side wall of a garage space. It is what

[0011]

Since the garage space is provided on the first floor of the building, the garage can be secured even when the building is set up in a place where the residential area is small. Further, since the drainage pipe attached to the housing equipment provided on the second floor is attached along the side wall of the garage space from the garage space and the room of the housing equipment, the drainage pipe does not protrude from the outer wall.
Therefore, the drain pipe is not exposed to wind and rain, and the cover does not necessarily have to be provided. Further, since this drainage pipe is hung down and attached along the side wall of the garage, when installing or repairing the drainage pipe, it is sufficient to work in the garage space. Therefore, it is possible to work without hindrance even when it is raining or snowing, or when the wind is strong.
Further, since the drainage pipe is provided in the garage, the noise of the drainage flowing through the drainage pipe to the outside of the room or the building is less audible, which improves the habitability and does not bother the neighborhood.

In this way, since the drainage pipe hangs down along the side wall of the garage and is attached, the drain pipe is located above the garage space.
It is not necessary to provide the housing equipment provided in the room on the floor along the inside of the outer wall as in the conventional case, and thus the degree of freedom in the mounting position of the housing equipment is increased. According to the second aspect of the present invention, when a plurality of garage units are installed side by side so that the short sides of the rectangle are substantially aligned with each other, the long side portions of the rectangle without floor beams become the communicating portions. Therefore, by setting this side surface as a place where the vehicle passes, a garage space can be provided without any trouble.

In the skeleton of the garage unit used in the second aspect of the present invention, since two floor beams connecting the lower portions of the four columns along the short sides are provided, the skeleton unit is seen from the long side direction. For the power of, it has the same structure as the conventional building unit,
It is strong. Also, since four floor beam pieces protruding from the bottom of the four columns along the long side are provided and these floor beam pieces are fixed to the foundation, they are also strong against the force from the short side direction. . Also, by attaching a temporary floor beam to this floor beam small piece and attaching this temporary floor beam to the loading platform, it can be firmly attached to the vehicle and does not deform, so the garage unit may move or be damaged during transportation. There is nothing to do. Further, when the temporary floor beam is attached, it is hoisted by a wrecker or the like at the time of installation, but it is not deformed at that time.

According to the second aspect of the present invention, when a plurality of garage units are installed side by side so that the short sides of the rectangle are substantially straight, four floor beam pieces protruding along the long sides are installed. It projects inside the garage. Therefore, the vehicle does not pass near the floor beam small pieces. Similarly, the vehicle does not pass through the corners of the garage unit. In the present invention, since the drainage pipe passes through a corner portion where this vehicle does not pass or the floor beam small piece, the drainage pipe does not interfere with the entrance and exit of the vehicle.

According to the third aspect of the invention, since the drain pipe is attached with a detachable cover, the drain pipe is not visible and the vicinity of the drain pipe is beautiful. When repairing, the drain pipe can be easily repaired by removing this cover. Further, since the cover is provided in the garage space, the cover is not exposed to rain and wind. Therefore, this cover may be made of a material having inferior weather resistance and water resistance when it is provided outdoors, or it may have a simple structure because it does not need to be watertight. Further, when the cover is provided in this way, the sound is further reduced, and the habitability is further improved, which does not disturb the neighborhood.
