Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apartment house suitable for rent, which has flexibility in changing the floor plan and area of each house after construction.

[0002]

[Prior art and its problems]

A conventional housing complex (condominium) is disclosed in
The floor plans and floor areas are generally fixed except for some skeleton-infill structures such as SI housing complex No. 002-021348, so the floor plans and individual floor areas may change due to changes in the times or the needs of residents or lifestyle changes. Even if you want to change, you cannot change it easily. In particular, when looking at the aging society in the future, it is expected that the degree of freedom to change the floor plan and the area of each house for barrier-free will arise as a large market need. From the viewpoint of, it is expected that such needs will remarkably emerge. A housing structure that facilitates such changes in floor plans or changes in the area of each house is an area that is expected to develop in the future as it maintains the asset value of the building for a long period of time.

In the SI apartment house of JP-A-2002-021348, the entire area of each house has a double floor, and even a living area where a double floor is originally unnecessary is a double floor. Therefore, there is a problem that the cost is high and the floor height is unnecessarily high, resulting in a lot of waste.

An object of the present invention is to provide an apartment house in which the degree of freedom in changing the floor plan and changing the area of each house can be greatly improved at a low cost. Another object of the present invention is to suppress the floor height to a conventional level.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, an apartment house of the present invention is an apartment house in which a plurality of dwelling units are continuously constructed facing a common corridor, and the plurality of dwelling units are connected in series. The specified number of dwelling units are divided into multiple groups by seismic resistant walls as one group, and the dwelling units in each group are partitioned by dry soundproof and fire resistant walls, and
The common corridor area of each dwelling unit in one group is constructed with a skeleton and infill structure with a continuous double floor across the lower part of the dry soundproof fireproof wall, and piping wiring is housed inside the double floor This is possible (claim 1).

Here, the skeleton is a skeleton that forms the skeleton of a building, and is specifically a pillar, a beam, a slab, a wall, or the like. The infill is the contents of the building, and includes partitions, equipment, interiors, and the like. In the above configuration, since the double floor part is limited to the common corridor side area instead of the entire area of each dwelling unit, it is possible to reduce the average dwelling unit cost and also to move or remove the dry soundproof fireproof wall. It is possible to freely increase or decrease the area of the dwelling unit, and in that case, since the double floor part is continuous in each unit, regardless of the installation position of the dry soundproof fireproof wall, the double floor is used for each unit after the change in the unit area. It is easy to redraw the piping and wiring through the part, and it is possible to freely change the layout of the infill centering on the water supply facility in particular.

Further, in the housing complex of the present invention, the pipe space is formed in the vertical direction inside the beams arranged along the common corridor, and the pipe wirings arranged in the pipe space are connected to the double floor. It is characterized in that it is connected to the piping and wirings housed inside (claim 2). This is to avoid forming a pipe space through hole in the beam itself.

Further, in the apartment house of the present invention, the ceiling slabs for each door on the floors lower than the uppermost floor are lowered one step in the common corridor side area and one step higher in the area opposite to the common corridor, so that both areas are closed. It is characterized in that the double floor is constituted by steps. This is to prevent an increase in floor slab thickness or floor height due to double floors.

Further, the housing complex of the present invention is characterized in that the common corridor side area having the double floor is about 60% of the area of the dwelling unit (claim 4). This 60% figure has the implication of ensuring a sufficient double floor area if necessary. This is because, as mentioned above, the double floor is a factor that increases the cost, so it must be minimized, while a certain amount of area is required to secure the degree of freedom in the floor plan. In that sense, the fact that the double-floor area is about 60% of the area of the dwelling unit is a double-floor area that is necessary and sufficient to satisfy both cost and floor plan flexibility, based on the simulation results of construction costs. Can be said.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial plan view of a first floor of an apartment house according to the present invention, and FIG. 2 is a plan view of a portion above the second floor. As is clear from the figure, this housing complex has a plurality of (6) 2DK dwelling units 2a facing the common corridor 1 and continuously constructed in a straight line. The partition wall 3 between the three consecutive dwelling units 2a has a board system and an AL for easy removal.
It is composed of a C type dry soundproof fireproof wall 3. The partition wall 4 between two groups of which three groups are one group is configured by a so-called earthquake-resistant wall 4 which forms a part of the skeleton structure such as a reinforced concrete structure. The right half of the earthquake-resistant wall 4 in FIGS. 1 and 2 is enlarged and shown in FIG.

4 to 6 show an example of a floor plan in which the area of each house and the number of rooms are changed. FIG. 4 shows the dry soundproof fireproof wall 3 as in FIGS. 2DK housing unit 2
Similarly, a is a 1LDK dwelling unit 2b of 3 units in one group. In FIG. 5, one dry soundproof fireproof wall 3 is removed in the right half of the earthquake resistant wall 4 of FIGS. 1 and 2 to form a group of 2 units of 4LDK dwelling unit 2c and 2DK dwelling unit 2a. In FIG. 6, one dry sound insulation fire wall 3 is removed in the right half of the earthquake resistance wall 4 of FIGS. 1 and 2, and the remaining dry sound insulation fire wall 3 is removed.
Are moved to the center to form a group of 2 units of 3LDK housing units 2d. In the figure, 5 is an entrance, 6 is a storage case, 7 is a pipe space, 8 is a bathroom of a unit bath, 9 is a toilet, 10 is a toilet, 11 is a kitchen, 12 is a Western-style room, 13 is a living room, and 14 is a balcony.

As described above, the number of units and the area of each unit can be variously changed within the range of one group house, and particularly in the rental housing complex, it is possible to quickly and flexibly respond to the trend of the rental market.

As shown in FIG. 7, the floor slab layer S1 in the common corridor side area 20 of each house is one step lower than the floor slab layer S2 in the area 30 (balcony side) opposite to the common corridor 1 (specifically, Is 10 centimeters lower). Normally, the thickness of the floor slab layer is 40 cm, but in the present invention, the thickness of the floor slab layers S1 and S2 is 20 cm in principle, and the common corridor 1 within the range of the conventional floor slab layer thickness of 40 cm. Steps are provided on the door slab layers S1 and S2 on the side of the balcony and on the side of the balcony 14. In the space created by the step between the common corridor side area 20 and the balcony side area 30, plumbing wiring is properly installed, and on the floating floor 25 provided thereon, water for bathroom, washroom, kitchen, etc. The surrounding equipment and other areas will be appropriately partitioned. Then, the necessary partition wall is constructed with a panel member as an infill. It should be noted that the water supply / drainage pipe and gas pipe of the kitchen 11 on the balcony side of FIG. 5 should be constructed by constructing a double wall on the earthquake-resistant wall side and connecting it to the water supply / drainage pipe and gas pipe in the double floor on the shared corridor side through the inside. .

The pipes and wires in the double floor are the pipes and wires arranged vertically in the pipe space (water pipe, hot water supply pipe, sewer pipe, gas pipe, electric power line, telephone line, TV cable). Cable, optical fiber cable, etc.). The pipe space is formed on the inside of the beam so that the pipes and wirings can pass vertically through each floor without being disturbed by the beam 28 arranged along the common corridor.

A balcony 14 is usually provided on the side opposite to the common corridor 1, but since the living ceiling slab layer S2 adjacent to the balcony 14 can be made higher by 20 cm than the conventional one, the window side beam is a forward beam. Even so, a sense of openness is created.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, one group of three units or two units of two units is included. Although an example of a group is shown, the number of units may be determined as necessary, and one unit having the maximum area may be set to one group, or four units or more may be set to one group. Therefore, assuming that the minimum area of dwelling units is, for example, 50 m ² and this constitutes one group of 3 units, a maximum of 1 dwelling unit of 150 m ² is possible, and 100 m ² and 50 m ² dwelling units are formed one by one, ^Two 75 m ² dwelling units can be formed.

[0018]

As described above, the present invention provides a housing complex in which a plurality of dwelling units are continuously constructed facing the common corridor,
The above-mentioned plurality of dwelling units are divided into a plurality of continuous dwelling units as a group by seismic resistant walls, and the dwelling units in each group are partitioned by dry soundproof fireproof walls, and one group The common corridor area of each dwelling unit inside is constructed with a skeleton and infill structure with a continuous double floor across the lower part of the dry soundproof fireproof wall, and piping wiring can be stored inside the double floor As a result, the number of units and the area of each unit can be freely changed within the range of one group dwelling unit, and the layout can be freely changed by the skeleton and the infill structure on the shared corridor side. Can respond flexibly to rental market trends at low cost.
