DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an SI apartment house in which the living area of one dwelling unit can be changed without remodeling the skeleton by separating the skeleton from the infill.

[0002]

2. Description of the Related Art In recent years, research and development of SI homes (separated skeleton / infill homes) have been actively conducted for the purpose of supplying high quality homes in the future. An SI house is a house in which a skeleton that is a skeleton of a house and an infill that is an internal structure thereof are separated, and the infill can be built and remodeled independently of the skeleton. In the following, the SI house that targets the apartment house is referred to as “SI apartment house”.

In an apartment house, a skeleton (structural skeleton) is used.
Is a space defined by columns 52, beams 53, earthquake-resistant walls 54, and slabs 55 made of reinforced concrete, for example, as shown in FIG. This space is usually treated as a single dwelling unit (one dwelling unit). Also, infill (interior)
Is an internal structure of the skeleton, and generally includes piping and the like in addition to the interior. Reference numeral 57 denotes a drain stack.

[0004]

The conventional apartment house illustrated in FIG. 3 has a problem that it is practically difficult to change the living area of one dwelling unit unless the skeleton (structural frame) is largely changed. .

Therefore, as illustrated in FIG. 4, the distance (frontage) between the skeleton columns 52 is increased, and
2. An SI apartment house in which the space defined by the beam 53, the earthquake-resistant wall 54, and the slab 55 is widened in advance has been considered. In this case, the door border 56 divides the area according to the required area.

However, when the width of the pillar 52 is increased, it becomes difficult to install a common vertical pipe such as a water supply pipe, a gas pipe, a drain pipe, and an electric main line when the section is variously changed. For example, in the example of FIG. 4, since the position of the drain stack 57 on the upper and lower floors cannot be changed, in the case of a living space not adjacent to the drain stack 57 (for example, the three middle houses at the right end), the front of the adjacent house is It is necessary to install drain pipes and the like up to the drain stack 57 through the common corridor. for that reason,
There was a problem that hindered access to the adjacent house. In particular, when the drain pipe is provided with a gradient, the height of the projection is further increased.

In order to solve this problem, as shown in FIG. 5, an apartment house using a reverse beam 53 in which a beam is raised from both ends of a slab 55 is also known. In this case, the floor is made into a double floor using the reverse beam 53, the supply pipes such as water supply pipes and gas pipes and the drain pipes are piped using the underfloor space, and the exhaust duct is used using the ceiling part. 59 is provided. In this structure, the exhaust duct 59 is a structural beam 5
Since it does not penetrate through 3, it has an advantage that it can be arranged at any position according to the division and layout of the dwelling unit.

However, the double floor formed by the inverted beams 53 has a beam structure (total height of the beams) of, for example, about 900 mm, so that unnecessary extra underfloor space is formed in piping and the like. Therefore, it is necessary to make the floor height higher than usual in order to secure a sufficient ceiling height, and there are problems such as the number of floors of the building being reduced and the construction cost per unit being increased. Also, in order to realize an SI apartment house, the common standpipe is to be disposed outside the frame such as a column and a beam. As a result, the branch pipe branched from the common standpipe to each dwelling unit passes through the reverse beam 53. This is not preferred.

The present invention has been made to solve such a problem. That is, an object of the present invention is to separate the skeleton and the infill and change the living area of one dwelling unit without remodeling the skeleton, and it is possible to install a common pipe with almost no effect on each dwelling unit. It is an object of the present invention to provide an SI apartment house that has a small underfloor space or a space under the ceiling and can secure a sufficient ceiling height without increasing the floor height.

[0010]

And the ceiling (1) connected to the partition wall (8) separating the living space and the common corridor and the lower end of the beam (2) on the balcony side of the upper floor.
Thus, a floor space (12) is formed under the floor, and a ceiling space (13) is formed under the ceiling. With this configuration, a floor space (12) is formed below the floor, and a ceiling space (13) is formed below the ceiling, and this space can be used for equipment piping.

It is preferable that the thickness from the lower floor ceiling surface to the upper floor surface is substantially equal to the beam structure of the beam (2) (total height of the beam).
With this configuration, useless underfloor space or space above the ceiling can be reduced, and facility piping can be installed without providing a through hole or the like in the beam (2).

Also, a piping space (15) partitioned by a floor plate (14) connected to the rising portion (7) and the upper end of the common corridor-side beam (2), and a balcony-side beam (2).
And a piping space (15 ') partitioned by a top plate (14') connected to a lower end of the piping space (15, 15 ').
At least one is connected to a meter box (16) formed along the pillar (1). With this configuration, the floor space (12) and the ceiling space (13) can be provided from the meter box (16) via the piping spaces (15, 15 ') without providing a through hole or the like in a structural member (for example, reinforced concrete) constituting the skeleton. ), It is possible to install equipment pipes, and to eliminate pipes exposed in living spaces and common corridors.
