Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house provided with a carport on a lower floor and a drainage facility on an upper floor.

[0002]

2. Description of the Related Art Hitherto, buildings having a structure in which a car port for parking a car is provided have been built. Such buildings are widely used not only in relatively large buildings used for offices and the like, but also in general houses with the spread of private cars in recent years.

For example, Japanese Patent Application Laid-Open No. Hei 9-137504 proposes a unit-type building having a carport. Note that the unit-type building is constructed by combining a plurality of box-shaped building units, and the building unit has, for example, a rectangular parallelepiped shape in which upper and lower ends of four pillars are connected by upper beams and lower beams. It has a frame.
In the building unit described in the above publication, four pillars are provided, and a lower beam is erected between lower ends of the pillars except at least between the pair of pillars, and upper ends of a pair of pillars without the lower beam are provided. An upper beam, which is a lattice beam, is erected between them. With the above-described configuration, it is possible to have sufficient rigidity and sufficiently secure the height of the opening (the entrance / exit of the carport).

[0004]

In general, when a facility for draining water is provided above a living space, a pipe space provided on an outer wall portion of a lower floor (a living space) is provided. , Water pipes and drain pipes were led to each facility. However, when the lower floor is a carport, there is no outer wall at the opening that will be the entrance and exit of the car.Therefore, when installing equipment for draining almost above the opening, each drain pipe and water supply The pipe had to be guided from the outer wall of the lower floor, which did not become an opening.

[0005] At this time, for example, the drain pipe and the water supply pipe are routed under the floor of the upper floor. In this case, the space under the floor of the upper floor is limited. For example, when installing a bathtub or a storage room below the floor below the floor surface, determine the arrangement of drainage pipes and water supply pipes so as to avoid the bathtub or storage room below the floor, It was necessary to decide the arrangement of the bathtub and storage in consideration of the position. In particular, in a bathroom provided with a bathtub, for example, the bottom of the bathtub may be lower than the floor outside the bathroom, and the washing area may be lower than the floor outside the bathroom, and the bathroom is a unit bath. In such a case, the bathtub of the unit bath protrudes under the floor and the other part may also protrude under the floor, so that the space under the floor is occupied over a wide area, and the pipes are routed at that part. Was sometimes difficult. Also, in a barrier-free unit bath in which the floor of the washing room in the bathroom is almost the same height as the floor outside the bathroom, parts other than the bathtub protrude below the floor due to drains surrounding the washing room. And a similar problem has arisen. In general, a washroom is arranged adjacent to the bathroom. At this time, a parking space is constructed below the washroom, and the drain pipe of the washbasin must be routed to the bathroom for the above-described reason. In such a case, it was difficult to pipe a drain pipe.

The present invention has been made in view of the above circumstances, and a facility for discharging drainage is arranged on the upper floor of a carport.
It is another object of the present invention to provide a house that can secure a sufficient degree of freedom in the layout of the upper floor.

[0007]

In order to achieve the above object, a house according to claim 1 of the present invention is constructed as shown in FIGS.
As shown in the figure, the vehicle has at least two upper and lower levels, and a parking space (carport) 1 is formed in a lower level, which is a lower level, and an upper level, which is an upper level above the lower level. Equipment for draining water to a position almost above the parking space 1 (bath 5
1. In a house where one or more washbasins 61) are provided,
The part of the drain pipe 65 connected to the drainage facilities 51 and 61 for discharging water in the upper floor part and being arranged to be lowered to the lower part of the lower floor part and extending substantially horizontally is disposed as described above. The parking space 1 in the parking space 1 on the lower floor below the boundary between the upper floor and the lower floor is provided.

[0008] Here, the equipment for discharging the drainage is, for example,
Provided in bathroom 5, washroom 6, toilet, kitchen, etc.,
A bathtub 51, a sink 61, a toilet bowl, a sink, and the like.

In the house according to the first aspect, the drain pipe 65 communicated with the drainage facilities 51, 61 on the upper floor.
Of the parking space 1 on the lower floor portion below the boundary between the upper floor portion and the lower floor portion, that is, the portion extending in the horizontal direction of the parking space 1 In the case where facilities 51 and 61 for draining water are provided on the upper floor portion at a position substantially above the parking space 1, the space 51 serves as an entrance and exit for the parking space 1 and an outer wall surrounding the parking space 1. When lowering the drainage pipe 65 so as to avoid the opening 12, it is not necessary to route the drainage pipe 65 under the floor of the upper floor, and the pipe is routed at the ceiling back part 19 of the lower floor. Therefore, unlike the related art, the space under the floor in the upper floor is not limited by the piping below the floor, and the space below the floor in the upper floor can be used freely. In other words, the piping position of the drain pipe 65b drawn in the lateral direction is
The drain pipe 65 can be freely laid out in the lateral direction in the space 19 below the ceiling of the parking space 1 on the lower floor without being affected by the facilities such as the bathtub 51 and the like. In addition, even if the drain pipe 65 is disposed in the back part 19 of the ceiling, it is not the living room but the back of the ceiling of the parking space 1, so that it is not necessary to take special soundproofing measures for piping under the floor. In particular, piping costs do not increase. In addition, parking space 1
Is formed on the lower floor, the portion of the parking space 1 is basically a dirt floor, and the floor of the parking space 1 is lower than the floor of the living room. Therefore, even if the height of the ceiling is lower than that of other rooms in order to perform piping in the back part 19 of the ceiling, since the floor is low, the height from the floor to the ceiling does not become particularly low.

The house according to claim 2 is the house according to claim 1, wherein the upper and lower ends of the four pillars (31...) Are upper beams (32a, 32b, 42a) and lower beams (33).
A unit building constructed by combining a plurality of building units each having a rectangular parallelepiped frame and connected to a lower floor building unit (carport unit) 4 having the parking space 1. The upper-floor building unit 9 is provided with the drainage facilities 51 and 61 described above.
Is provided.

[0011] In the house of the second aspect, the same effect as the configuration of the first aspect can be obtained. That is,
By making the house described in claim 1 a unit-type building, it is possible to increase the number of variations in the layout of the house in the unit-type building. That is, for example, when plumbing pipes under the floor, the arrangement of the plumbing pipes under the floor limits the arrangement of bathtubs drawn in below the floor surface and storages under the floor, and conversely, bathtubs etc. In some cases, the plumbing of the water supply / drainage pipe may become difficult due to the arrangement of the drainage pipe.
, The space under the floor of the upper floor building unit 9 in the upper floor can be used freely. In a unit-type building, the upper and lower beams of the building unit serve as boundary of the story, so if the upper-floor building unit is equipped with drainage equipment, The plumbing pipes must be routed between the position of the lower beam and the position of the upper beam on the lower floor, but the lower beam and the upper beam may interfere with the routing of the piping, When there is an intermediate beam bridged between the lower beams, the intermediate beam sometimes becomes an obstacle. However, when the drainage pipe 65 is routed horizontally in the lower part of the ceiling 19 on the lower floor below the boundary between the upper and lower floors, the lower and upper beams 32a, 32b, 42a, and the intermediate beam 49 do not interfere with each other. Instead, the drain pipe 65 can be routed in the horizontal direction and piped.

According to a third aspect of the present invention, in the house of the second aspect, the lower-floor building units (carport units) 3 and 4 having the parking space 1 are open at lower left and right sides thereof. It is characterized in that it has a substantially gate shape in which the upper ends of the left and right sides are connected to each other, and lattice beams 38 and 48 are bridged between the upper ends of the left and right sides.

Here, the lattice beam refers to a beam using a web material formed obliquely or in a zigzag shape.

According to the third aspect of the present invention, the beams bridged between the upper ends of the left and right sides of the lower-floor building units 3 and 4, that is, the upper beams 32a, 32b and 42a are connected to the lattice beams 38 which are wide vertically. By setting it to 48, the ceiling back part 19 in the lower floor can be widened up and down. Therefore,
The drain pipe 65 that is provided on the upper floor and guides to the drainage facilities 51 and 61 can be sufficiently routed in the ceiling back part 19 of the lower floor. In addition, the lattice beams 38 and 48 have lower gates that are formed between the lower ends of the left and right sides in a normal building unit by making the lower-floor building units 3 and 4 have a substantially gate shape. In this case, the shear deformation of the lower building units 3 and 4 is reduced, and
a, 42a so that the bending strength can be obtained.

According to a fourth aspect of the present invention, in the house according to any one of the first to third aspects, a bathroom 5 and a bathroom are provided on the upper floor at a position substantially above the parking space 1. 5 is provided with a washroom 6 adjacent thereto, and a position (piping space) 16 where the bathroom 5 lowers the pipe of the washroom 6 to the lower part of the lower floor, or between the position 16 and the washroom 6 It is characterized by being arranged.

When a bathroom and a washroom adjacent to the bathroom are provided at a position above the parking space as in the above configuration, two or more facilities for draining water (for example, a bathtub and a washstand, etc.) are provided. ), The drain pipes of at least one of the two drainage facilities are installed horizontally under the floor so that the drainpipe of the drainage facility is close to the drainpipe side of the other drainage facility. It is preferable to drop it to the lower side of the first floor in the piping space at the location. Also, for example, when there is an opening of a parking space or an outer wall for a parking space below the washroom, and there is no outer wall portion where a piping space to the lower part of the lower floor can be arranged below the vicinity of the washroom. It is necessary to pipe the drain pipe of the washroom to the outer wall side with no opening under the floor, but in this case if it becomes necessary to pipe the pipe below the bathroom, as described above, the bathroom , The drain pipe is difficult to pipe. Therefore, as described above, the drain pipe 65 of the washroom 6 is connected to the lower part 19 of the ceiling.
The drain pipe 65 can be routed on the lower side of the bathroom 5. Therefore, the arrangement of the washroom 6 and the bathroom 5 above the parking space 1 is not limited, and the arrangement of each facility on the upper floor can be freely planned. In other words, the drain pipe 65 of the washroom 6 or the like can be freely routed and arranged below the bathroom 5.

A house according to a fifth aspect of the present invention is the house according to any one of the first to fourth aspects, wherein the upper floor portion is provided with a bathroom 5 and a washroom at a position substantially above the parking space 1. 6, and the washroom 5 is provided at a position away from the outer wall portion 14 where the piping space 16 extending vertically above and below the lower floor can be arranged, and the bathroom 5 is vertically above and below the lower floor. Is provided in the vicinity of the outer wall portion 14 where the piping space 16 extending to the outside can be arranged.

Here, the outer wall portion in which a vertically extending piping space can be arranged is, for example, an opening portion which serves as an entrance or exit of a parking lot or an opening portion such as a normal window or door. It is a portion where the piping space can be arranged up and down between the outer wall and the interior surface on the indoor side. According to the above configuration, even if the drain pipe on the side of the washroom is to be lowered almost at that position as described above, the drain pipe cannot be passed through the parking space or the opening thereof, and Even if it is attempted to lower the drain pipe together with the pipe, it becomes difficult to pass the drain pipe from the washroom side to the bathroom side as described above. The drain pipe 65 is routed from the side of the washroom 6 to the lower side of the bathroom 5 by passing the drain pipe 65 through the drainage pipe 65, and the drain pipe of the bathroom 5 and the drain pipe 65 of the washroom 6 are combined to form an outer wall portion on the bathroom 5 side. A drain pipe 65 can be provided along the lower side of the lower floor along the line 14. In addition, the drain pipe 65 of the washroom 6 with relatively little drainage is connected to the lower part 1 of the ceiling.
9 can be routed.

A piping space 16 for guiding the drain pipe is provided vertically.

On the second floor of the house, as shown in FIG. 2, a bathroom 5 is provided at a position substantially above the carport 1, and a washroom 6 is provided adjacent to the bathroom 5. Have been. On the carport unit 4 arranged on the indoor side, an upper-floor building unit 9 which is a normal building unit, that is, upper and lower ends of four pillars are connected by an upper beam and a lower beam. A rectangular parallelepiped frame is installed. Inside this upper floor building unit 9,
The bathroom 5, the washroom 6, and the corridor 7 provided adjacent to the washroom 6 are arranged. A balcony 8 is provided above the carport unit 3 arranged outside the house.

The bathroom 5 is provided with a bathtub 51 and a washing place 52 as shown in FIG. The bathroom 5 is installed along an outer wall portion 14 that separates the carport 1 from the outside of the house. Facilities for draining the bathroom 5, such as a bathtub 51 and a shower (not shown), are provided. It is arranged near the position to be the piping space 16.

The washroom 6 is provided with a washstand 61 as shown in FIG. The washroom 6 is provided adjacent to the bathroom 5, and an entrance 62 is provided at a boundary between the washroom 6 and the bathroom 5. The floor of the washroom 6 is substantially the same height as the floor of the bathroom 5, and has a so-called barrier-free structure. In addition, wash basin 61
The lower side of the (bathroom 6) is a parking space and the entrance 2 and has a structure in which there is no outer wall in which a piping space extending up and down can be arranged nearby. It is difficult to secure the space for piping to directly lower the piping to the lower part of the first floor.

In the wash basin 61 provided in the wash basin 6, as shown in FIGS. 3 and 4, a water supply pipe and a drain pipe 65 a communicating with the wash basin 61 are located at the lateral position of the wash basin 61. As will be described later, the carport unit 4 is disposed below the ceiling back portion 19 of the carport unit 4. In addition, the dropping position 66 of each pipe may be a space between the inner wall of the washroom 6 and the outer wall of the house, or may be inside the washroom 6. Downwardly directed water and drain pipes 65a
Is the underside 19 of the carport unit 4 on the first floor,
That is, between the upper beam 42a and the horizontal erection beam 46 in FIG. 6, each of the water supply pipes and the drain pipes 65b arranged in the horizontal direction is communicated.

As shown in FIG. 4, each pipe provided in the ceiling back portion 19 is provided along the upper beam of the carport unit 4 provided on the indoor side of the first floor, and The ceiling space 19 communicates with the piping space 16. By arranging each pipe along the upper beam 42a, that is, along the side edge of the ceiling back portion 19 of the carport unit 4, the indoor space of the ceiling back portion 19 can be used for other purposes such as storage. And so on. The water supply pipe and the drain pipe 65b are not limited to this.
May be routed on the indoor side of the ceiling back portion 19 to communicate with the piping space 16.

At the upper part of the piping space 16, as shown in FIG. 3, the above-mentioned pipes (drain pipes 65b) arranged in the horizontal direction are communicated with the water supply pipe and the drain pipe 65c of the piping space 16. ing. With such a configuration, the above-described piping space 1 is installed in a facility (a wash basin 61 or the like) that drains water on the second floor provided substantially above the parking space.
From 6, a water supply pipe and a drain pipe 65 are led. Thereby, water is supplied to the wash basin 61 of the wash room 6 on the second floor,
Further, water can be drained from the sink 61.

In the bathroom 5, the piping space 1 is connected to a drainage facility such as a bathtub 51 and a shower facility.
From 6, a water supply pipe and a drain pipe (not shown) communicate with each other. Since the bathroom 5 is located substantially above the piping space 16, the water supply pipe and the drain pipe can be communicated by disposing the piping downward substantially above the piping space 16. In some cases, depending on the arrangement of the facilities for draining each drain in the bathroom 5, dropping pipes cannot be formed almost above the piping space 16. In this case, however, the pipes are installed at the ceiling back part 19 of the carport unit 4 on the first floor. , The water supply pipe and the drain pipe can be communicated.

As described above, in this example, the lower floor (the first floor)
A drain pipe 65 communicated with a facility (bathtub 51, wash basin 61, etc.) for draining water from the upper floor (second floor) to the ceiling back portion 19 of the building.
Since b is provided, there is no need to run a drain pipe under the floor of the second floor. Therefore, conventionally, when a facility for discharging water was provided almost above the parking space, a drain pipe had to be routed under the floor of the second floor. Since there is no need for a space under the floor for the drain pipe, the space under the floor on the second floor can be used freely.

In the parking space on the first floor, the ceiling back part 19 is provided by the lattice beam 48 formed in the carport unit 4, so that a large space can be secured in the ceiling back part 19. . Therefore, the drain pipe 65 for leading to the drainage facility on the second floor can be routed in the ceiling back portion 19 having a sufficiently large space.

Further, since it is not necessary to route the drain pipe in the underfloor portion of the second floor, the layout of the underfloor of the second floor portion can be freely determined. In other words, even when the bottom of the unit bus projects below the floor of the second floor and it is difficult to route the plumbing pipes under the floor, the plumbing pipe 65 can be routed at the ceiling back part 19 of the carport on the first floor. it can.

In addition, with the above-described piping, the drain pipe 65 of the washroom 6 with relatively little drainage can be routed around the ceiling back portion 19 on the first floor.

In this example, a house is constructed by combining a plurality of building units. However, the present invention is not limited to this. For example, a wooden house, a steel structure building, and a plurality of panels may be used. It may be a house with a panel construction method.

Although the bathroom 5 and the washroom 6 are provided almost above the parking space, the invention is not limited to this.
For example, a room such as a toilet or a kitchen provided with a drainage facility may be provided substantially above the parking space.

In this example, the house has three stories. However, the present invention is not limited to this. If it has two or more stories, it has two or more stories and four or more stories. It may be a building.

[0040]

As described above, according to the first aspect of the present invention,
According to the house, since there is no need to route a drain pipe under the floor of the upper floor, unlike the conventional case, the space under the floor of the upper floor is not limited by the piping under the floor, and You can use the space freely. In other words, since the bottom of the unit bus projects below the floor of the upper floor, even if piping under the floor is difficult, piping can be freely performed in the lower part of the parking space behind the ceiling of the parking space. .

According to the second aspect of the present invention, since the drainage pipe is disposed in the lower part of the ceiling of the lower-floor building unit provided on the lower floor, the underfloor space of the upper-floor building unit can be used freely. .

According to the third aspect of the present invention, since the upper beam of the lower-floor building unit, which has a substantially gate shape for providing a parking space, is formed as a lattice beam to enhance the strength, the ceiling of the lower floor portion is provided. Even if piping is performed on the back part, the space behind the ceiling on the lower floor can be widened, and the space for piping can be widened. Therefore, piping can be easily performed in the lower part of the ceiling.

According to the fourth aspect of the present invention, even if the bathroom projects below the floor of the upper floor, the drain pipe of the washroom is routed around the lower part of the ceiling of the lower floor. Can be routed below the bathroom, so that the arrangement of the washroom and the bathroom is not restricted above the parking space, and the arrangement of each facility on the upper floor can be freely planned.

According to the fifth aspect of the present invention, the drain pipe of the washroom with relatively little drainage can be routed around the lower part of the ceiling.
