Description

  The present invention relates to a building having two or more floors.

  Conventionally, in a building for an apartment house (apartment, apartment, etc.) having two or more floors, when a bathroom is provided on each floor and a unit bath is provided in each bathroom, the bathroom on each floor is viewed in a vertical direction and viewed on a plane. They are arranged at the same position (hereinafter, also referred to as linear arrangement). This makes it possible to efficiently arrange the pipes for supplying and draining water to and from the bathroom, and to suppress adverse effects such as water leakage from affecting the living room. The underfloor slab in the area where the unit baths are installed (including the surrounding area) is more than the underfloor slab in other areas in order to secure space for drainage piping when barrier-free is realized. It is lowered downward (hereinafter also referred to as a slab lowering structure).

  On the other hand, the height of a building is restricted according to the area by the Building Standards Law. Specifically, the building height is limited to 10 m or less or 12 m or less depending on the type of the use area. In some cases, it is necessary to keep the building height low based on the shading regulations.

JP 2002-138618 A

  When a unit bath is installed under such a height restriction, the ceiling height of the unit bus may have to be set low due to the linear arrangement and the slab falling structure described above. For example, when constructing a four-story apartment house in an area where the building height is limited to 10 m or less, it is necessary to keep the floor height low. In this case, the ceiling height of the unit bus can be secured only about 1900 mm. Such a problem is not limited to a four-story building or an apartment building, but is common to any two-story or more building in which a bathroom having a unit bath is provided on each floor under height restrictions. For this reason, there is a need for a two-story or more building in which the ceiling height of the unit bus can be set higher than before while satisfying the building height restriction.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as, for example, the following modes.

  According to the first aspect of the present invention, a building having two or more floors is provided. This building has odd and even floors. Each of the odd and even floors has a bathroom with a unit bath. Bathrooms on odd floors are arranged in a first area on a plane, and bathrooms on even floors are arranged in a second area on a plane. At least the underfloor slabs of the first region and the second region have a slab descent structure whose height is relatively reduced. The first region is arranged at a position not overlapping with the second region when viewed in the vertical direction.

  According to such a building, the bathroom having the unit bath does not continue at the same position in the vertical direction between the odd-numbered floor and the even-numbered floor. That is, the slab lowering structure of the bathroom is not continuous in the vertical direction. Therefore, the ceiling height of the unit bath can be set higher than before by the height of one slab descent structure as compared with the conventional building in which the slab descent structure of the bathroom is continuous in the vertical direction.

  According to the second mode of the present invention, in the first mode, the first region and the second region are arranged adjacent to each other when viewed in the vertical direction. According to this mode, the bathroom on the odd-numbered floor and the bathroom on the even-numbered floor are arranged at positions adjacent to each other when viewed in the vertical direction. Therefore, the pipes for supplying and draining water to and from the bathroom can be efficiently arranged, and adverse effects such as water leakage can be suppressed from reaching the living room.

  According to a third aspect of the present invention, in the first or second aspect, the building comprises a pipe space. The first region and the second region are symmetrically arranged with the pipe space as a reference position when viewed in the vertical direction. The pipe space is shared by the water supply and drainage for the bathroom on the odd-numbered floor and the water supply and drainage for the bathroom on the even-numbered floor. According to this embodiment, the plumbing for supplying and draining water to and from the bathroom can be more efficiently arranged.

  According to the fourth aspect of the present invention, in any one of the first to third aspects, the odd-numbered range hood is arranged so as to avoid an odd-numbered area corresponding to the second area when viewed in the vertical direction. Is done. The even-numbered range hood is arranged so as to avoid an even-numbered floor area corresponding to the first area when viewed in the vertical direction. According to this mode, since the range hood is arranged so as to avoid the place where the slab is lowered in the bathroom on the immediately higher floor, the floor height at the place where the range hood is installed is not reduced due to the arrangement of the bathroom. . That is, the degree of freedom in setting the range hood is improved.

  According to the fifth aspect of the present invention, in any one of the first to fourth aspects, at least one of the washroom and the toilet is located in the area on the odd-numbered floor corresponding to the second area when viewed in the vertical direction. Be placed. At least one of the washroom and the toilet is arranged in the area on the even-numbered floor corresponding to the first area when viewed in the vertical direction. According to this embodiment, the pipes related to the bathroom, the washroom, and the toilet can be efficiently arranged, and the adverse effects such as water leakage can be suppressed from reaching the living room. Further, the effect according to the fourth embodiment can be obtained.

  According to the sixth aspect of the present invention, in the fifth aspect, the drainage pipe from the odd-numbered floor toilet and the drainage pipe from the even-numbered toilet are connected to one common drainage vertical pipe. According to such an embodiment, wastewater of the waste can be efficiently discharged. Also, the wastewater drainage pipe can be efficiently arranged so as to be substantially symmetrical when viewed in the vertical direction.

  According to the seventh aspect of the present invention, in the fifth or sixth aspect, a drain pipe from a bathroom and a washroom on an odd-numbered floor and a drain pipe from a bathroom and a washroom on an even-numbered floor are common. Connected to one vertical drain. According to this mode, the wastewater from the household wastewater system can be efficiently discharged. Further, the drainage pipes of the household drainage system can be efficiently arranged so as to be substantially symmetrical when viewed in the vertical direction.

A. First embodiment:
FIG. 1 is a plan view of a first or third floor and a second or fourth floor of a building 20 according to a first embodiment of the present invention. In the present embodiment, the building 20 is exemplified as a 4-story 1K apartment. In this embodiment, the height of the building 20 is set to 9.99 m. FIG. 1A is a plan view of the first and third floors, and FIG. 1B is a plan view of the second and fourth floors. There are a plurality of rooms on each floor of the building 20, but FIG. 1 shows only one room. Each room of the building 20 includes a living room (Western-style room) 30, a kitchen 40, a bathroom 50, a washroom 60, a toilet 70, and a PS (pipe space) 80.

  FIG. 2 is a sectional view taken along line X1-X1 of FIG. FIG. 3 is a sectional view taken along line Y1-Y1 of FIG. In FIGS. 2 and 3, the floor is indicated at the end of each code via “−”. For example, the bathroom 50 on the second floor is indicated as “50-2”. As shown in FIGS. 2 and 3, the bathrooms 50 on odd-numbered floors (here, the first and third floors) are arranged at the same position when viewed in the vertical direction. The area where the bathroom 50 on the odd floor is arranged is also referred to as a first area. The bathrooms 50 on even-numbered floors (here, the second and fourth floors) are arranged at the same position when viewed in the vertical direction. The area where the bathroom 50 on the even-numbered floor is arranged is also referred to as a second area. As shown in FIG. 2, the first region and the second region are arranged at positions that do not overlap each other when viewed in the vertical direction.

  In the present embodiment, the first region and the second region are adjacent to each other when viewed in the vertical direction. For this reason, piping for supplying and draining water to the bathroom 50 on each floor can be efficiently arranged. In addition, it is possible to suppress the adverse effects such as when water leaks from the bathroom 50 or its piping from reaching the living room 30.

  In other words, the first area and the second area are alternately arranged along the vertical direction. Specifically, as shown in FIG. 1, on odd-numbered floors, the bathroom 50 is disposed on one side in the lateral direction of the room (left side in the drawing) on the entrance side in the longitudinal direction of the room. The washroom 60 and the toilet 70 are arranged adjacent to the bathroom 50 in the longitudinal direction. On the opposite side (the other side in the lateral direction) of the bathroom 50, the washroom 60, and the toilet 70, a kitchen 40 is arranged. On the other hand, on the even-numbered floor, the bathroom 50 is arranged on the other side in the short direction (right side in the drawing) on the entrance side in the longitudinal direction. The washroom 60 and the toilet 70 are arranged adjacent to the bathroom 50 in the longitudinal direction. On the opposite side (one side in the lateral direction) of the bathroom 50, the washroom 60, and the toilet 70, a kitchen 40 is arranged. That is, in the first embodiment, the bathroom 50, the washroom 60, the toilet 70, and the kitchen 40 are alternately arranged along the vertical direction.

  Further, as shown in FIG. 1, the PS 80 is disposed substantially at the center in the lateral direction. As a result, the first area and the second area (that is, the bathroom 50, the washroom 60, and the toilet 70) are arranged symmetrically in the short direction with the PS80 as a reference position. For this reason, the piping for supplying and draining water to and from the bathroom 50 can be more efficiently arranged.

  As shown in FIGS. 2 and 3, a unit bath 51 is installed in each of the bathrooms 50. In order to install the unit bath 51, the underfloor slab 52 of the bathroom 50 has a slab descent structure in which the underfloor slab is locally lowered when viewed from the upper floor. Specifically, the underfloor slab 52 of the bathroom 50 is lowered below the underfloor slabs of other locations (in FIGS. 2 and 3, the underfloor slab 42 of the kitchen 40 and the underfloor slab 32 of the living room 30). And locally concave. In the space between the underfloor slab 52 and the unit bath 51 in the bathroom 50, piping for water supply and drainage is laid. Further, ventilation equipment and piping for ventilation are laid between the underfloor slab on the immediately higher floor and the bathroom 50. In this embodiment, as shown in FIG. 3, the underfloor slab 62 of the washroom 60 also has a slab lowering structure. The range around the bathroom 50 up to the slab-down structure may be set according to the piping design around the water.

  Due to the staggered arrangement of the bathrooms 50 described above, slab descent structures will also occur every other floor. For this reason, the ceiling height of the bathroom 50 can be set higher by the height of one slab drop than the linear arrangement in which the bathrooms 50 on each floor are linearly arranged at the same position in the vertical direction. As a result, the ceiling height of the unit bus 51 can be set high. In the conventional linear arrangement, the ceiling height of the unit bus 51 is limited to about 1900 mm, but according to the building 20 of the present embodiment, a ceiling height of about 2000 mm can be realized.

On the other hand, on the even-numbered floor, when viewed from the entrance side, the bathroom 150, the washroom 160, and the toilet 170 are arranged in the longitudinal direction on one side in the short direction. That is, the bathroom 150, the washroom 160, and the toilet 170 are arranged alternately between the odd and even floors. The PS 180 is arranged in the longitudinal direction over a range where the washroom 160 and the toilet 170 are arranged. As shown in FIGS. 6 and 7, the underfloor slab 152 of the bathroom 150 is lower than the underfloor slab of other places (for example, the underfloor slab 142 of the kitchen 140), and has a slab lowering structure. 4 and 5, the lower part of the floor slab on the floor is shown as an area A1, and the lower part of the floor slab on the lower floor is shown as an area A2. With such an arrangement, the same effect as in the first embodiment can be obtained.

  In addition, by interchanging the positions of the bathroom 150 and the positions of the washroom 160 and the toilet 170 between the odd and even floors, as shown in FIG. 140 can be arranged. As a result, the range hood 141 of the kitchen 140 is arranged in an area of the floor where the slab descent structure is avoided. According to such an arrangement, the floor height of the installation location of the range hood 141 is not reduced due to the arrangement of the bathroom 150. That is, the degree of freedom in installing the range hood 141 is improved.
