Description

  The present invention relates to a dwelling unit structure using a cantilever effectively and a dwelling unit structure of an apartment house such as a condominium. More specifically, the present invention relates to a dwelling unit structure that effectively uses a cantilever that improves the degree of freedom of floor plan and a dwelling unit structure of an apartment house such as a condominium.

  In general, a dwelling unit of an apartment house such as an apartment employs a structure formed in a substantially rectangular shape in plan view from the viewpoint of maintaining the strength of the apartment house such as an apartment and effectively using the building area. For example, a dwelling unit having a generally rectangular shape in a plan view is generally formed so that the length in the depth direction is longer than the length in the frontage direction. In such a dwelling unit, living in a space surrounded by horizontally formed upper and lower slabs and walls provided between the upper and lower slabs (for example, a boundary wall between adjacent dwelling units or an outer wall of an apartment, etc.) An exclusive part is formed. And this resident exclusive part is equipped with several living rooms such as living room (L), dining room (D), bedroom, etc., kitchen (K), washroom, toilet, bathroom etc. There is a common hallway, balcony and veranda outside.

  In recent years, there is a desire to change the layout (layout) of living rooms and the like in a residential exclusive unit in accordance with changes in the future family structure and lifestyle.

  However, in the general dwelling unit as described above, there is a problem in that the degree of freedom when changing the floor plan is limited by the watering equipment.

  The water supply equipment supplies drinking water and the like from the water pipe and drains used water through the drain pipe. In general, clean water is stored in a tank provided at the uppermost part of the apartment house, and is supplied to the dwelling units below using gravity drop. In addition, the wastewater is sent from the dwelling unit to a wastewater treatment facility provided on the ground or underground in the vicinity of the apartment house using gravity drop. That is, both the method for supplying clean water and the method for draining drainage use gravity drop. For this reason, a water pipe and a drain pipe provided in a general apartment house are arranged so as to penetrate through the dwelling units on the upper and lower floors of the apartment house from the top floor to the lowest floor in a substantially vertical direction. In other words, the water pipe and the drain pipe are formed so that both ends thereof are located on the same axis (hereinafter, this water pipe is referred to as a water tank pipe, and this drain pipe is referred to as a drain pipe). Since such water supply pipes and horizontal drainage pipes are shared items in apartment buildings such as condominiums, residents in each dwelling unit can freely replace such water supply pipes and horizontal drainage pipes, or change the piping shape. I can't. Therefore, as described above, the degree of freedom of the floor plan is limited by the watering equipment.

  Flexibility of the floor plan can be increased by bending the saddle pipe arranged in the occupying occupancy part with respect to the central axis. However, the occupants of each dwelling unit cannot be freely changed as described above. Even if it is a case where consent is obtained about changing, by bending these dredging pipes in the middle, the flow passage resistance of the drainage which flows inside becomes large in the bent portion. In particular, in the drainage pipe, when drainage flows through this bent portion, the bent portion becomes a resistance and unpleasant noise such as a falling sound and an impact sound is generated. For this reason, the range in which the drainage pipe can be moved is limited to a slight distance from the original position. In other words, it is not realistic to move these dredging pipes, particularly drainage dredging pipes.

  Then, the dwelling unit structure where the freedom degree of a floor plan is not restrict | limited by the water around facilities is proposed (for example, patent documents 1, 2).

  In Patent Document 1 or Patent Document 2, the water supply pipe and the drainage pipe are accommodated in a pipe shaft (PS) disposed on the shared corridor side of the resident exclusive part, and the interior floor of the resident exclusive part is a floor slab. Water and drainage pipes (hereinafter referred to as water supply horizontal pipes) that are connected to the water supply and drainage pipes and the watering equipment. And a dwelling unit structure in which a drainage horizontal pipe) is disposed in an underfloor space. In these dwelling unit structures, horizontal piping can be freely arranged in the underfloor space, so the position of the watering equipment can be freely changed, so the degree of freedom of the floor plan is not limited by the watering equipment. Since there is no need to bend the drainage pipe, there is an advantage that noise due to the falling sound of the drainage is not generated.

  However, in the dwelling unit structure of Patent Document 1 or Patent Document 2, among the horizontal water pipes and drainage horizontal pipes arranged in the underfloor space, the drainage pipes, in particular, the drainage flowing inside the drainage pipes are drained from the water facilities. It is necessary to be provided with a sufficient gradient (for example, about 1/50 to 1/75) so that it can flow satisfactorily while dropping to the pipe. However, from the viewpoint of construction cost, the height of the underfloor space (that is, the distance from the upper surface of the floor slab to the lower surface of the interior floor) can generally only be about 300 mm. Such a restriction also limits the length of the drainage horizontal pipe. Then, in the dwelling unit structure of patent document 1 which employ | adopts a double floor structure as an underfloor structure, there exists a problem that the distance between a drainage pipe and watering equipment is restrict | limited to some extent. In other words, even in a dwelling unit structure that adopts a double floor structure, the degree of freedom in floor plan is limited to some extent.

  In recent years, water-saving toilets have been popularized from the viewpoint of energy saving and ecology. In the water-saving toilet, the amount of water used during drainage is extremely smaller than that of a conventional toilet, and therefore, it is necessary to further strengthen the slope of the drainage horizontal pipe disposed under the floor of the double floor structure described above. This is because, when a water-saving toilet is used, the amount of drainage is smaller than in the conventional case, so that the conventional gradient causes a problem that dirt or the like is clogged in the horizontal pipe. In other words, when a water-saving toilet is adopted, the distance between the drainage pipe and the water-saving toilet is limited to be shorter, so that the degree of freedom in layout is further limited.

  And in the dwelling unit structure of patent document 1 or patent document 1 which employ | adopted the double floor structure, the distance (henceforth ceiling height) between the upper surface of an interior floor and a ceiling surface becomes small only by the height of underfloor space. (For example, the ceiling height is about 2100 mm). If the ceiling height of the living room is 2100mm or more, it is recognized as a living room under the Building Standards Act, but at present, when the ceiling height of a general apartment house has a ceiling height of 2400mm or more, the dwelling unit with such a ceiling height is It is a height that makes the residents feel a sense of oppression. For this reason, the dwelling unit which has such a ceiling height also has a problem that it is avoided from the purchaser who is considering the purchase of the dwelling unit of the apartment house.

  On the other hand, when adopting a double-floor structure and a dwelling structure with a ceiling height of 2400 mm or more, the distance from the upper surface of the floor slab to the upper surface of the ceiling slab (so-called floor height) is equal to the height of the underfloor space. Need to be high. In this case, the number of floors that can be built is generally higher in an apartment house where the construction cost is higher than in the case of an apartment house in which general dwelling units that do not have a double floor structure are stacked, or the building height is limited. There was a problem that it was less than a typical apartment house. As a result, there arises a problem that the price of the dwelling unit must be increased.

  In view of the above circumstances, the present invention is a dwelling unit that effectively uses a cantilever that maintains a floor height equivalent to the conventional level, has a ceiling height that prevents residents from feeling pressure, and improves the degree of freedom in floor plan. It aims at providing the dwelling unit structure of apartment houses, such as a structure and an apartment.

The dwelling unit structure that effectively utilizes the cantilever of the first device is provided so as to protrude outward along a substantially box-shaped residential exclusive part having a plurality of rooms and one side wall constituting the exclusive residential part. A dwelling unit structure of a dwelling unit provided with a veranda, wherein the dwelling unit can be used as a drainage pipe and a common water pipe that can be used as a common drainage pipe that vertically penetrates each dwelling unit on the upper and lower floors A pipe shaft in which a water supply pipe is accommodated is provided, and the pipe shaft is provided in the vicinity of one side wall and / or on the veranda.
The dwelling unit structure of an apartment house such as a condominium of the second device is a dwelling unit structure of a dwelling unit having a substantially box-like residence-exclusive part having a plurality of rooms in an apartment house having a plurality of residence units, In this case, all pipe shafts are provided in the vicinity of one side wall, and in the pipe shaft, drainage pipes that can be used as a common drainage pipe that vertically penetrates each dwelling unit on the upper and lower floors and a common upper pipe. It is characterized by containing a tap water pipe that can be used as a water pipe.
The dwelling unit structure of an apartment house such as a condominium of the third device in the second device is provided with the veranda so as to protrude outward along the one side wall, and the pipe shaft is provided on the veranda. It is characterized by being.
The dwelling unit structure of an apartment house such as an apartment of the fourth device is characterized in that, in the first or third device, a watering facility is provided on the veranda.
The dwelling unit structure of an apartment house such as a condominium of the fifth device is the housing unit of the fourth device, wherein the floor is composed of a floor slab and an interior floor provided on the upper surface of the floor slab. The veranda is provided with a cantilever slab portion that constitutes a floor portion thereof, and the cantilever slab is provided with a water-floored floor portion that is held in a floating state from the upper surface of the cantilever slab. The water floor portion is formed such that the floor surface thereof is substantially flush with the upper surface of the interior floor in a state where the water circulation facility is disposed.
The dwelling unit structure of an apartment house such as a condominium of the sixth device is the first, third, fourth, fifth or fifth device, wherein the veranda is provided so as to protrude outward along the one side wall. And a rear veranda that is continuously extended so as to be substantially orthogonal to the axial direction of the veranda.

According to the first device, all pipe shafts can be provided in the vicinity of one side wall and / or on the veranda of the occupancy occupancy part. For this reason, if the watering equipment is arranged in the vicinity of the pipe shaft, the watering equipment can be concentrated in one place in the residential exclusive part and / or the veranda. As a result, the degree of freedom in the floor plan can be improved as compared with the case where the water supply facilities are installed in the vicinity of the substantially central part of the occupancy exclusive part. For example, if the occupying exclusive part is a substantially rectangular shape in plan view, a space that can be arranged can be formed in a substantially U shape or L shape in plan view. In addition, if a pipe shaft is provided on the veranda, the interior of the occupying occupancy can be cleaned.
According to the second device, all pipe shafts are provided in the vicinity of one side wall of the resident exclusive part. Therefore, if the water supply equipment is arranged in the vicinity of the pipe shaft, the water supply equipment is provided in one place in the resident exclusive part. Can be aggregated. As a result, the degree of freedom in the floor plan can be improved as compared with the case where the water supply facilities are installed in the vicinity of the substantially central part of the occupancy exclusive part. For example, if the occupying exclusive part is a substantially rectangular shape in plan view, a space that can be arranged can be formed in a substantially U shape or L shape in plan view.
According to the third device, since the pipe shaft is provided on the veranda, it is possible to clean the interior of the residential exclusive part.
According to the 4th device, since the water facilities such as bathrooms, washrooms, toilets, kitchens, etc. are arranged on the veranda, there is a space that can be laid out in the occupancy occupancy area by the area of the water facilities arranged on the veranda. Can be increased. Then, compared with the case where most watering facilities are provided in the residential exclusive part, the degree of freedom of the floor plan can be improved. For example, if all the water supply facilities are arranged on the veranda, the area of the residential exclusive part is the same, and the degree of freedom of the floor plan is equal compared to the dwelling unit structure where the interior floor of the residential exclusive part is a double floor structure Can be. In addition, since there is no watering equipment in the resident-occupied part, the entire occupying part of the resident-occupied part can be used for living rooms, etc., so the degree of freedom in the floor plan can be improved compared to the dwelling unit structure that uses a double floor structure. . Furthermore, since there is no need for a double floor structure, the floor space and the ceiling height that the occupants do not feel oppressive (for example, about 2400 mm) should be maintained while the occupancy is free. Can do. In other words, the resident of the dwelling unit can surely use a private space (for example, a space having a height from the upper surface of the floor slab to the ceiling) that can be used freely. Moreover, since the construction cost can be kept low as compared with the case of adopting the double floor structure while improving the degree of freedom of the floor plan, the dwelling unit price can be kept down.
According to the fifth device, since the water floor has a structure having an underfloor space, a horizontal drainage pipe and a clean water horizontal pipe used for a plurality of water circulation facilities can be disposed in the underfloor. In other words, it is possible to reliably arrange a plurality of water facilities on the veranda. For example, place bathrooms, toilets, washrooms, etc. on the veranda, and connect drainage horizontal pipes and clean water horizontal pipes from these watering equipment to the drainage and plumbing pipes contained in the pipe shaft, respectively. Can do. In addition, the floor of the water floor and the interior floor of the resident-occupied part are formed so that they are almost flush with the water supply equipment, so that the flow of the residents is smoother. Can be formed. In other words, since there is no step between the resident-occupied part and the watering equipment on the veranda, it is possible to prevent a small child or an elderly person from crawling and falling.
According to the sixth device, the rear veranda is extended so as to be continuous from the veranda in order to arrange the watering equipment, so the function of the general veranda as a whole (the clothes drying place and the rear veranda are used for the evacuation route. This space can be used effectively while maintaining

  On the other hand, on the side veranda 4 constituting the veranda 3, a washroom 24 and a bathroom 22 used as a watering facility 20 are provided along the side walls 6 in this order from the back veranda 5 side toward the shared corridor side. Is provided. The washroom 24 and the bathroom 22 are provided so as to be located at a substantially central portion of the side wall 6. A pipe shaft 2 c is provided between the washroom 24 and the bathroom 22.

The vertical water pipe p1 and the drainage pipe p2 are pipes arranged so as to penetrate the upper and lower floor dwelling units of the apartment house from the top floor to the bottom floor in a substantially vertical direction. That is, in the state of being arranged in such a state, both the pipes are arranged so that both ends thereof are located on the same axis.
Further, the water supply facility 20 is provided with a horizontal water pipe so as to connect a faucet or the like of each facility and the vertical water pipe p1, and so as to connect the drain port of each facility and the drainage pipe p2. Drainage horizontal piping is provided. For example, as shown in FIG. 4, the bathroom 22 and the washroom 24 include drainage horizontal pipes 22p2 and 24p2 connected to a drainage pipe p2, and horizontal water supply pipes 22p1 connected to a not shown drainage pipe p1. 22p2 is provided.

  If the living room 11 and the watering equipment 20 are arranged as described above and the watering equipment 20 is provided in the vicinity of one side wall of the resident exclusive part 10, all the pipe shafts 2 are provided in the vicinity of one side wall of the resident exclusive part 10. It can be provided to be located.

  For example, as shown in FIG. 1, the watering equipment 20 such as the kitchen 23 can be concentrated and arranged in the vicinity of the substantially central portion of the side wall 6. In other words, all the pipe shafts 2 can be provided so as to be concentrated in the vicinity of a substantially central portion of the side wall 6 (for example, within a radius of about 2 m with respect to the side wall). That is, all the pipe shafts 2a and 2b provided in the occupying exclusive part 10 can be provided limitedly within a range of a radius of about 2 m from the substantially central part of the side wall 6. In this case, in the floor space 10h in the resident exclusive part 10, the living room 11 other than the watering facility 20 can be arranged at a desired position, and the degree of freedom in the layout (layout) of the living room 11 can be improved. .

Specifically, since only the watering equipment 20 and the pipe shaft 2 are provided in the vicinity of the substantially central portion of the one side wall 6, in the floor space 10 h in the occupying exclusive part 10, the side veranda 8 extends from the side wall 8 on the shared hallway side. A floor space 10h that communicates up to 5 can be formed.
For example, as shown in FIG. 2, a space 10 h in which a substantially L-shaped floor plan can be formed can be formed in the residential exclusive part 10. In the space 10h in which such a substantially L-shaped floor space can be provided, a wall between the living rooms 11 can be freely provided, so that the living room 11 having a free shape or size can be formed, or an accessory of the living room 11 (for example, a closet or the like) ) Can be formed freely. That is, the degree of freedom of the floor plan can be improved as compared with a general dwelling unit structure in which a watering facility is also provided in the vicinity of the substantially central part in the occupancy exclusive part.

  In addition, as shown in FIG. 5, you may provide the bathroom 22 used as the watering equipment 20 in the part which faces the shared corridor of the side veranda 4. In this case, the water supply facilities 20 such as the bathroom 22, the washroom 24, the toilet 21, and the kitchen 23 can be collectively arranged at one corner portion of the occupancy dedicated portion 10 having a substantially rectangular shape in plan view. Then, the floor area of the sanitary space having the bathroom 22, the washroom 24, and the toilet 21 can be widened, and a space 10h capable of a substantially L-shaped floor space is formed in the resident exclusive part 10 as described above. be able to.

(Description of the dwelling unit structure in which the pipe shaft 2 is provided on the side veranda 4)
In particular, a dwelling unit structure in which all the pipe shafts 2 provided in the residential exclusive part 10 are provided on the side veranda 4 is preferable. In this case, since all the watering equipment 20 can be excluded from the resident exclusive part 10 of the dwelling unit structure 1, the floor plan in the resident exclusive part 10 is equivalent to the floor area of the watering equipment 20 arranged on the side veranda 4. The floor area of the space 10h can be increased. In other words, the resident exclusive part 10 can form a space having almost nothing in the interior in a state where the living room 11 and the like are excluded from the interior. As a result, the degree of freedom in layout (layout) can be further improved as compared with the case where most of the watering facilities 20 are provided in the resident exclusive part 10.

  For example, as shown in FIG. 3, in the side veranda 4, the kitchen 23, the washroom 24, the bathroom 22, the toilet 21, and the like are arranged in this order from the rear veranda 5. Then, as shown in FIG. 3, the floor area of the floor space 10 h in the occupancy exclusive part 10 can be formed to be substantially the same as the floor area of the floor slab 1 s constituting the floor part of the occupancy exclusive part 10. .

  As described above, if all the water-circulating facilities 20 are arranged on the side veranda 4, the floor area of the floor slab 1s constituting the floor portion of the resident exclusive part 10 is the same, and the interior floor of the resident exclusive part 10 is provided. Compared to a double-floor structure dwelling unit structure, the degree of freedom in floor plan can be made equal.

  Moreover, in the dwelling unit structure 1 of the present embodiment, since the watering facility 20 is not arranged in the resident exclusive part 10, the entire resident exclusive part 10 can be used for the living room 11 or the like. Then, compared with the dwelling unit structure which made the interior floor of the residence exclusive part the double floor structure, the freedom degree of floor space can be improved more.

  Furthermore, in the dwelling unit structure 1 of this embodiment, since it is not necessary to have a double floor structure, the floor height and the ceiling height that the occupants do not feel pressure (for example, about 2400 mm) are maintained while All the spaces in the exclusive part 10 can be laid out freely. In other words, the resident of the dwelling unit can surely use an exclusive space (for example, a space having a height from the upper surface of the floor slab 1s to the ceiling) that can be used freely. In addition, the construction cost can be kept low as compared with the case where the double floor structure is adopted while improving the degree of freedom of the floor plan, and the dwelling unit price can also be kept down.

  In addition, as shown in FIG. 3, it is preferable to provide the kitchen 23 so as to be the face-to-face kitchen 23 because the kitchen spare can be used more effectively.

(Description of the floor of the side veranda 4)
Moreover, when the watering equipment 20 is provided in the side veranda 4, it is preferable to set it as the following structures.
For example, as shown in FIG. 3, a so-called sanitary room is provided on the side veranda 4 from the entrance / exit of the bathroom 22 to the washroom 24, and the floor surface SAfs of the sanitary room floor SAf is the interior floor of the occupancy exclusive unit 10. It is preferably formed so as to be substantially flush with the floor surface of 10f.

  For example, in FIG. 4, the side veranda 4 includes a cantilever slab 4 s that extends continuously from the outer surface of the floor slab 1 s of the occupying exclusive part 10 that constitutes the floor, and And a handrail wall 4w erected at the end. And it is formed so that the thickness of the cantilevered slab 4s is substantially equal to the thickness of the floor slab 1s of the occupying occupancy part 10. Specifically, when the floor thickness of the floor slab 1s is about 150 mm to 200 mm, the floor thickness of the cantilevered slab 4s is formed to be equal. In this case, as described above, the cantilever slab 4s provided with the bathroom 22 and the sanitary room is separated from the upper surface, and the upper surface SAfs is substantially the same as the upper surface 10fs of the interior floor 10f of the occupancy exclusive part 10. A sanitary room floor SAf is provided so as to be uniform. That is, as shown in FIG. 4, the floor part SAf of the sanitary room is formed so as to have a double floor structure having an underfloor space SAfh under the floor.

  With the structure as described above, the drainage horizontal pipe 22p2 provided in the bathroom 22 and the drainage horizontal pipe 24p2 provided in the washroom 24 in the floor space SAfh of the sanitary room floor SAfh, Piping 22p1 and 24p1 can be arranged. That is, with this structure, even if the distance between the water-circulating facility 20 and the pipe shaft 2 is slightly separated, the horizontal water pipe and the horizontal drain pipe can be arranged in the underfloor space SAfh. Can be refreshed. In addition, since a plurality of water tank pipes p1 and the like can be arranged in the underfloor space SAfh, the pipe shaft 2 provided on the side veranda 4 only needs to be provided at one place.

  Moreover, the sanitary room floor SAf has a floor surface SAfs substantially equal to the floor surface 10fs of the interior floor 10f of the resident-occupied part 10 by a support member provided in the floor space SAfh of the sanitary room floor SAf (not shown). It is held to be flush. Then, if such a configuration, that is, the floor surface 10fs of the sanitary room floor surface SAfs and the interior floor 10f of the occupying exclusive part 10 is formed to be substantially flush with each other, the flow line of the resident is made smoother. Can be formed. Then, since there can be no step or the like from the residential exclusive part 10 to the sanitary room, it is possible to prevent a small child or an elderly person from scolding and falling.

  The sanitary room floor SAf is not particularly limited as long as it can be maintained in a state of being separated from the upper surface of the cantilever slab 4s. For example, the sanitary room floor SAf and the cantilever slab 4s A support member such as wood or a jack can be provided between the upper surfaces.

  The floor part SAf of the sanitary room corresponds to a watering floor part in the claims.

  Further, the veranda 3 shown in the present specification includes a balcony, a roof balcony and the like in addition to the veranda as described above.

(Other embodiments)
In addition, although the dwelling unit structure of this invention demonstrated the case where the veranda 3 was provided in the outer side of the residence exclusive part 10 in the example mentioned above, you may employ | adopt the dwelling unit structure of a structure which does not provide a veranda.
Specifically, all the pipe shafts 2 are collected in the vicinity of one side wall constituting the occupying exclusive part 10 of the dwelling unit structure 1 of the present invention. For example, the pipe shaft 2 is gathered in the middle part of the longitudinal direction in one side wall substantially orthogonal to the axial direction of the side wall having the entrance. And if it is set as the state which excluded the living room 11 grade | etc., From the inside of the residence exclusive part 10, the space 10h in which a substantially L-shaped floor plan can be formed can be formed like the case shown in FIG. Then, the same effect as the case where the watering equipment 20 shown in FIG. That is, even if the dwelling unit structure of the present invention is not provided with a veranda, the living room 11 and the watering facility 20 can be arranged at desired positions in the space 10h in which the floor space in the resident exclusive part 10 can be arranged.
