Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure suitable for arranging a water area such as a kitchen, a bathroom, a toilet, and a washroom of each dwelling unit at a free position in a building such as an apartment.

[0002]

2. Description of the Related Art Generally, a building such as a condominium is formed by vertically stacking dwelling units, and each dwelling unit has a slab that forms a floor and a ceiling and a boundary between an outer wall and an inner wall. It has a living space surrounded by walls. Outside the living space of each dwelling unit, an outer corridor, a balcony, etc. are provided adjacent to the living space, while in the living space of each dwelling unit, together with the living room, a kitchen, a bathroom, a toilet, and a washbasin. There are water stations in each area. In addition, the building is provided with a pipe shaft extending vertically through the living space of each dwelling unit, and inside the pipe shaft, the main pipes such as the water supply vertical pipe and the drain vertical pipe are provided. A vertical pipe extending in the vertical direction is disposed. The vertical pipe arranged in the pipe shaft and the water supply / drainage equipment of the water field of each dwelling unit are connected to each other through a lateral pipe such as a lateral water supply pipe or a lateral drainage pipe.

[0003]

However, in this case, since a space for the pipe shaft is required in the living space of the dwelling unit, a space that can be used for living in the living space,
That is, the floor area had decreased. Further, when the layout of the dwelling unit in the living space is changed after the building is constructed, it is impossible to move the existing pipe shaft if the pipe shaft is arranged in the living space of the dwelling unit. Therefore, if the position of the water field in the living space is moved away from the pipe shaft, the pipe shaft will remain there (at the position where the original water field was). In addition, since the pipe shaft remains at the position planned to be used for living in the living space, the living space cannot be effectively used. Further, if the water field is too far from the pipe shaft, the pipe length of the drainage horizontal pipe, which requires a water gradient with a large diameter, becomes long, and a height difference is required to obtain the water gradient of the drainage horizontal pipe. In the building of, for example, it is not possible to provide a drainage horizontal pipe having a pipe length that traverses the living space of a dwelling unit from the outer corridor side to the balcony side in a height below the floor between the slab and the floor. It was impossible. In other words, even if you try to change the floor plan in the living space of the dwelling unit due to changes in the family structure living in the dwelling unit of the building, or because the resident is replaced, the water field will only be in the vicinity of the existing pipe shaft. Since it was not possible to move and the location of the water area was almost fixed, the degree of freedom in changing the layout of the dwelling units was small, and the layout could not be changed as expected. Furthermore, since the pipe shafts are arranged in the vertical direction even at the time of selling or renting each of the residential units of the building, in the plurality of residential units that are continuous in the vertical direction, the water field of each residential unit and the pipe shaft are Had to be provided close to each other. In other words, it is difficult to arrange the water fields of these dwelling units connected in the vertical direction at completely different positions, that is, it is difficult to arrange the water fields independently of the positions of the water fields between the dwelling units, and the pipe shafts are arranged. The degree of freedom in changing the positions of the water fields of a plurality of dwelling units whose positions are continuous in the vertical direction is limited, that is, the type of floor plan of the dwelling units must be limited.

Therefore, in view of the above circumstances, the present invention provides a large space for living in each dwelling unit in a building, and has a great degree of freedom in arranging a water area such as a kitchen, a bathroom, a toilet, and a washroom in each dwelling unit. It is possible to change the floor plan of each dwelling unit easily and it is possible to set freely.

Since the condominium 1 to which the present invention is applied has the above-described structure, the first and second pipe shafts 21 and 22 are provided outside the living space 11a of the dwelling unit 10 so that the dwelling unit 10 can be occupied. Since the space for the pipe shafts 21 and 22 is not required in the space 11a, the space that can be used for living in the living space 11a, that is, the floor area can be made large. Further, since the pipe shafts 21 and 22 are not arranged in the living space 11a of each dwelling unit 10, when changing the floor plan in the living space 11a of the dwelling unit 10, the kitchen 12, the bathroom 13, the washroom 14 Also, even if the position of the water area such as the toilet 15 is moved, the pipe shaft does not remain there (at the position where the original water area was). In other words, those water fields (12, 13, 14, 15)
Even if the position is moved, the pipe shafts 21 and 22 do not remain at the position newly planned for use in the living space 11a, and the living space 11a can be effectively used. The degree of freedom in changing the floor plan of the dwelling unit 10 can be increased. Furthermore, the living space 1 of the dwelling unit 10

5) Underfloor space 4c of the multipurpose double floor 4 in which the pipe length of each drainage horizontal pipe 28 that requires a water gradient to be piped respectively
The position of the water field after each relocation should be adjusted so that it fits within the underfloor height such as the height of the pipe shaft 21 (2
2) can be selected respectively. In other words, the pipe length of each drain horizontal pipe 28 that should be piped to each of these water fields is a length that cannot be installed within the underfloor thickness (for example, the living space 11a of the dwelling unit 10 from the outer corridor 31 side to the balcony 32).
It does not have a length that runs vertically to the side). Therefore, for those water fields (12, 13, 14, 15) arranged at arbitrary positions in the living space 11a of the dwelling unit 10, the optimum pipe shaft 21 (22) is selected for each of the arranged water fields. By doing so, the drainage vertical pipe 26 disposed in each selected pipe shaft and the drainage portion 12b of each water field
b, 13bb, 14bb, and 15bb can be connected to each other via the drainage horizontal pipe 28 having the minimum required pipe length, and a more preferable floor plan change of the dwelling unit 10 can be performed. That is, the water fields (12, 13, 14, 15) can be freely moved without being affected by the positions of the pipe shafts 21, 22 both before and after the construction of the condominium 1. So, the kitchen 12 of each dwelling unit 10,
It is possible to give a great degree of freedom to the arrangement of water areas such as the bathroom 13, the washroom 14 and the toilet 15, and it is possible to freely set the floor plan of each dwelling unit 10.
Therefore, at the time of selling or renting out each dwelling unit 10 of the condominium 1, not only the floor plan of various dwelling units 10 (various dwelling unit plans) can be presented to the customer as an example, but also it is easy to meet the demands of diverse customers. In addition, since the layout of the dwelling unit 10 after living is flexible and large, it is possible to flexibly respond to the lifestyle and life stage of the resident, and change to the floor plan desired by the resident. It becomes possible to do. Further, by forming the pipe shafts 21 and 22 in contact with the pillar 2 and providing them in the condominium 1, since the pipe shafts 21 and 22 and the pillars 2 are integrally provided in the condominium 1, the outside of the condominium 1 The protruding portion is not formed innocently, and the scenery of the building such as the apartment building 1 can be improved. Also, the first and second spaces between the pillars 2 of the condominium 1
The outer walls 7 and 8 can be effectively used. Furthermore,
By forming the multipurpose double floor 4 on the slab 5 of the dwelling unit 10, the horizontal drain pipe 28 can be easily rearranged in the underfloor space 4c of the multipurpose double floor 4 even if the position of the water field is changed. Therefore, it becomes easier to change the floor plan of the dwelling unit 10. In addition to the drainage horizontal pipe 28, etc., the air conditioning pipe 57
Since the arrangement of the wiring (not shown) for the floor outlet 59 and the like can be easily changed, not only can the indoor unit 55, the floor heating device 56 and the floor outlet 59 be relocated easily, but also the maintenance of these pipes and wiring is easy. become. Further, since the outdoor unit 51 installed in the outdoor unit installation portion 51 does not project onto the balcony 32 in such a manner as to narrow the width of the outer floor surface 32a of the balcony 32, it does not hinder the passage of the balcony 32.
