Description

  The present invention relates to a building structure in which a frame structure having a ramen structure is arranged in the direction of the beam and a seismic wall is arranged in the direction between the beams, and is particularly suitable for a mid-to-high-rise apartment house.

Conventionally, a plurality of dwelling units continuously arranged in the column direction, a shared corridor arranged on one side of the plurality of dwelling units along the plurality of dwelling units, and a plurality of dwelling units along the plurality of dwelling units Mid-to-high-rise apartments with balconies on the other side are widely known.
As a structure of such an apartment building, there is known a structure in which the frame surface of the common corridor side and the balcony side is composed of a ramen structure and the direction between the beams is composed of multi-layer earthquake resistant walls. Columns and beams protrude into the dwelling units by the columns and beams that make up the ramen frame. When the pillar type or the beam type protrudes into the dwelling unit, the feeling of opening is impaired, and the height of the opening part such as a window and the position in the left and right direction are restricted, and there is a problem that the lighting performance and the view are deteriorated.
Patent Document 1 states that in a housing complex as described above, for the purpose of eliminating the beam type in the dwelling unit, “the main frame in the girder direction is composed of a ramen structure, and the main frame in the interbeam direction is composed of a seismic wall. The multi-story building is characterized in that the seismic reinforcement frame in the direction of the girder is composed of a mega brace structure that passes through the dwelling unit (Claim 1).
However, since the apartment house building described in Patent Document 1 has a mega brace structure that passes through the dwelling unit, the degree of freedom of the floor plan of the dwelling unit through which the mega brace passes is inevitably restricted.
In addition, Patent Document 2 discloses that “a dwelling unit is installed in a lateral direction for the purpose of obtaining a necessary strength as a structure without providing a structural member having a large cross section that protrudes from a ceiling or a floor in an opening. In the apartment house connected to the building, the door is a load-bearing wall, a reinforcing structure is provided in the center of the door, and the slab is supported by the door-bearing wall and the reinforcing structure. ing.
However, since the building described in Patent Document 2 is configured such that a reinforcing structure such as a wall column 25 is provided in the dwelling unit at a right angle to the door boundary wall 1, The degree of freedom of the floor plan is limited.

In the present invention, a frame surface of a ramen structure composed of columns and beams is arranged in the crossing direction on one side of the beam-to-beam direction, while the side opposite to the frame surface of the frame structure (the other side in the beam-to-beam direction). In such a column direction, there is no frame surface having such a ramen structure extending linearly in the column direction. The seismic wall is connected on one side in the inter-beam direction to a column located on one side in the inter-beam direction, but there is no column to be connected on the other side in the inter-beam direction. Do not connect to the pillar on the side.
The thin wall of the earthquake-resistant wall and the thick wall of the earthquake-resistant wall are continuously integrated, and a single plate-shaped earthquake-resistant wall is formed by the thick wall of the earthquake-resistant wall and the thin wall of the earthquake-resistant wall. Moreover, the floor slab thick part and the floor slab thin part are continuously integrated.

This structural part is composed of a member that is thinner than an ordinary rigid frame structure and forms a rigid frame structure that extends in a band shape in plan view, and the strength of the other side in the inter-beam direction is ensured by the structural part. Accordingly, in the present invention, horizontal rigidity and proof stress in the direction of the entire building are ensured with a composite form (combination) of the frame surface of the ramen structure and the structure portion having an outer shape approximate to a wall structure. Yes.
In addition, in the beam-to-beam direction, one side of the earthquake-resistant wall (multi-layer earthquake-resistant wall) is joined and integrated with the column of the frame structure of the frame structure, and the earthquake-resistant wall is arranged in the direction of the beam. And the proof stress is secured.
Furthermore, the seismic force is reduced by supporting the entire building with a seismic isolation device.

In the present invention, the structure type of the frame surface of the ramen structure composed of columns and beams is not particularly limited, such as steel structure, steel reinforced concrete structure (SRC structure), reinforced concrete structure (RC structure), steel concrete structure (SC structure), and the like. .
Moreover, the earthquake-resistant wall of each layer of the earthquake-resistant wall arranged in multiple layers over a plurality of layers is composed of a single plate-like earthquake-resistant wall, and is usually made of reinforced concrete.

The thick wall of the earthquake-resistant wall is provided with main bars and shear reinforcement bars (hoops) like a column, and bears rigidity and strength. The thin wall of the earthquake-resistant wall bears a part of rigidity and proof strength mainly by ensuring sound insulation performance.
Usually, the thick wall of the earthquake-resistant wall has a thickness of about 250 to 400 mm, the thin wall of the earthquake-resistant wall has a thickness of about 180 to 230 mm, and the thickness of the thick wall of the earthquake-resistant wall is equal to that of the thin wall of the earthquake-resistant wall. It is about 1.1 to 2.2 times the thickness.
In addition, in the inter-beam direction, the earthquake-resistant wall has a length D1 of the earthquake-resistant wall thin portion, a length D2 of the earthquake-resistant wall thick portion, and a total length of the earthquake-resistant wall D3. In the building, a range of D1: D2 = 1: 0.3 to 1: 0.45 is preferable. This is to ensure sound insulation and vibration resistance, avoid an increase in the wall thickness of the thick wall of the earthquake-resistant wall, and ensure the strength of the structure.

The seismic walls to be arranged in the direction of the beam are provided on the other side in the beam-to-beam direction with a relatively thick and rigid seismic wall thick part. By providing a floor slab thick part with relatively large thickness and rigidity at the corresponding position, the strength of the other side in the inter-beam direction is ensured. There is no structural frame. For this reason, it is not necessary to provide a mega brace or a reinforcing member that passes through the dwelling unit, it is possible to prevent protrusion of the floor plan and the beam type into the room without reducing the degree of freedom of the floor plan, and the width of the opening. The degree of freedom of position, etc. can be improved, and it is open and easy to use, and good lighting and view can be obtained.
In addition, since the thick wall part of the earthquake-resistant wall and the thick wall part of the floor slab do not extend over the entire length of the earthquake-resistant wall in the beam-to-beam direction, the material cost such as the amount of concrete used for the earthquake-resistant wall and floor slab And an increase in the weight of the building can be suppressed. The balance of the building is also good.
In addition, it is not easy to build a high-rise building in a conventional wall-type structure, but because it has the above-described configuration and seismic isolation device, it exhibits about 20 floors while demonstrating the goodness that approximates the wall-type structure. Can be built up to height.

An efficient plan in which the degree of freedom of the height, width, position, etc. of the opening is improved is possible, and good lighting is obtained. For example, since there is no beam-shaped protrusion on the shared corridor side, the opening can be arranged at a high position in consideration of privacy.
