Description

  The present invention relates to a housing complex.

In collective housing, various ideas have been made for the purpose of effectively using the living space.
For example, the flat ramen structure is a structure in which the pillars and beams, which are the main structure, are flattened so that no pillars or beams are formed in the room, and space is effectively utilized.

  However, if the cross-sectional dimension of the main structure is reduced in this way, there is a concern that the rigidity of the building will be reduced. For this reason, it is common to adopt a structural form that uses a seismic wall in conjunction with a reduction in the cross section of the main structure.

  For example, Patent Document 1 discloses a housing complex in which a core wall made of a square-walled earthquake-resistant wall is provided at the boundary between dwelling units.

JP-A-8-254024

The rectangular cylindrical core wall is generally formed facing the common part, such as around an elevator shaft or a staircase.
For this reason, when a core wall is formed in the central part between the dwelling units, the common part becomes large, and the degree of freedom in floor plan design may be reduced. On the other hand, if the position of the core wall is shifted in order to increase the degree of freedom in floor plan design, the core wall is disposed at a position that is biased on the plane.

  This invention solves the said problem, and it aims at proposing the housing complex which made it possible to improve the earthquake resistance of a housing complex, and to raise the freedom degree of floor space of living space. .

  In order to solve the above-mentioned problem, the present invention is an apartment house in which a pair of T-type earthquake-resistant walls are arranged on the border between adjacent dwelling units, and each T-type earthquake-resistant wall extends along the border. A pair of T-shapes are formed in a T-shape in plan view by a first wall formed and a second wall formed at one end of the first wall so as to be orthogonal to the first wall. The earthquake-resistant wall is characterized in that the second walls are arranged to face each other at a predetermined interval in the center of the door boundary.

According to such a housing complex, a pair of T-type earthquake-resistant walls formed in a T shape in plan view are arranged in the center of the doorway of the dwelling unit, so that the mechanical balance is good and the earthquake resistance is excellent. .
In addition, since the T-type seismic wall is T-shaped, the T-type seismic wall has a better fit at the doorway than the conventional square tube-shaped core wall, and the degree of freedom in the layout of the living space can be increased.

  If a flat wall pillar extends from the other end of the first wall along the door boundary, it becomes possible to secure a large opening in the direction of the crossing, and the degree of freedom in floor plan design is further increased. Can be increased.

  If the water circulation of the dwelling units is concentrated around the T-type earthquake-resistant wall, the space formed between the second walls is used as the aerial space for the facilities, so that the facility piping of each dwelling unit The horizontal piping can be shortened, and the degree of freedom in designing the living room space is further increased.

  ADVANTAGE OF THE INVENTION According to this invention, while having high earthquake resistance, it becomes possible to provide an apartment house with a high freedom degree of floor plan design.

  In the present embodiment, every other equipment void 3 is formed with respect to a plurality of doorways arranged side by side. That is, each dwelling unit 2 faces one equipment void 3. In addition, the equipment void 3 is formed in the center (intermediate part of a beam direction) of a door boundary.

The equipment void 3 is a space formed continuously in the vertical direction, and is used as a piping space in this embodiment.
The water surroundings of each dwelling unit 2 (kitchen 2a, bathroom / toilet 2b, toilet 2c, etc.) are arranged around the equipment void 3 so that the extension of the horizontal pulling of the equipment piping is shortened.

  A pair of T-type earthquake-resistant walls 10 and 10 are disposed at the door boundary where the equipment void 3 is formed. Further, a flat seismic wall 30 is formed on the doorway where there is no equipment void 3.

The T-type earthquake resistant wall 10 is formed by a first wall 11 and a second wall 12 in a T shape in plan view.
The T-type seismic wall 10 is fixedly fixed to the foundation beam at a foundation (not shown) and is continuous from the lower floor to the upper floor (see FIG. 2).

The first wall 11 is a plate-shaped member made of reinforced concrete and is formed along the door boundary.
A second wall 12 is formed at one end of the first wall 11, and the other end of the first wall 11 is connected to a wall column 21 formed along the door boundary.

  The second wall 12 is a reinforced concrete plate-like member formed integrally with the first wall 11, and is formed at one end of the first wall 11 so as to be orthogonal to the first wall 11.

  The pair of T-type earthquake-resistant walls 10 and 10 are arranged so that the second walls 12 face each other with a predetermined interval at the center of the door boundary (intermediate portion in the beam direction).

In the present embodiment, side end surfaces of the second walls 12 and 12 arranged so as to face each other are connected by U-shaped void walls 40 and 40 to form a rectangular space in plan view. A space surrounded by the second walls 12 and 12 and the void walls 40 and 40 is used as the equipment void 3.
The piping from the inside of each equipment pipe to the equipment void 3 is performed by penetrating the void wall 40. The void wall 40 is a non-structural wall (for example, a dry wall).

The earthquake-resistant wall 30 is a plate member made of reinforced concrete, and is formed along the door boundary. As shown in FIG. 2, the earthquake resistant wall 30 is continuously formed from the lower floor to the upper floor.
