Description

[Detailed description of the invention] Industrial applications The present invention relates to a high-rise apartment complex.

Conventional technology Generally speaking, in high-rise housing complexes where several housing units are arranged consecutively horizontally and vertically to form a single building, the surface of each housing unit that is in contact with the outside air is designed to ensure lighting, ventilation, etc. Because of this, it is necessary to have an open façade, so many of them are built with rigid frame structures that allow for wide openings.

Measures to solve the problem However, when using a rigid frame structure, the columns and beams protrude into the room, making processing and assembly of the formwork complicated, making the entire formwork work complex and significantly increasing the cost of the formwork work. There was a drawback. Moreover, there was also the drawback that the columns and beams were obstacles, making it impossible to plan the plan freely. Furthermore, in consideration of earthquake resistance, a large amount of reinforcing bars and steel frames had to be used and the cross-sectional strength had to be considerably increased, resulting in a significant increase in construction costs.

This invention was proposed in order to solve the above-mentioned conventional problems, and although it is a so-called wall-type structure, it is possible to secure the maximum opening on the surface that is in contact with the outside air, and it also allows for easy formwork construction. The purpose of the present invention is to provide a high-rise apartment complex that can be simplified and significantly reduce formwork construction costs and frame construction costs.

Means for Solving the Problems This invention provides an earthquake-resistant wall for each residential unit boundary wall in a high-rise apartment complex in which several residential units are arranged consecutively horizontally and vertically to form one residential building. Earthquake-resistant buttresses are installed on the sides of this boundary wall at right angles to the boundary wall, and the floor slabs on each floor are made of reinforced concrete or precast concrete plates using unbonded PC steel wire, and the lowest floor This objective is achieved by installing a seismic isolation device under the floor slab of the building.

Embodiment Hereinafter, the present invention will be described with reference to an illustrated embodiment. A high-rise apartment complex 1 is constructed by arranging several residential units 2, . . . consecutively in the horizontal and vertical directions.

The boundary walls 3 between the residential units 2, . . . are made of cast-in-place reinforced concrete and are constructed continuously in the direction of the upper and lower floors, and are designed as earthquake-resistant walls.

When constructing the door boundary wall 3, a large formwork is used and concrete is poured into the formwork while the large formwork is sequentially moved upward by a crane. Concrete will be poured to the bottom of the floor slab on each floor.

In the center of the door boundary wall 3, buttresses 4, 4 are connected to the door boundary wall 3.
It is configured to protrude at right angles on both sides of the The buttress 4 is made of reinforced concrete using formwork blocks and is constructed of continuous upper and lower floors, and is designed as a seismic wall. The construction of the buttress 4 shall be carried out after the construction of the door boundary wall 3 and the floor slab. Further, the placement of the buttress 4 shall be determined by considering the floor plan of the dwelling unit, preferably in the center.

The floor slab 5 on each floor is made of cast-in-place reinforced concrete, and a required number of unbonded PC steel wires are inserted into the floor slab 5. A large formwork (flying shore) is used to construct the floor slab 5, and this large formwork is sequentially moved to the upper floors by a crane and reused. Note that the floor slab 5 can also be constructed from a precast concrete board such as a Kaiser board or an FC board.

In the high-rise apartment complex 1 configured in this way, a seismic isolation device 6 made of laminated rubber, an elastoplastic damper, etc. is installed at the bottom of the floor slab 5 on the lowest floor, located directly below the partition walls 3, 3. The seismic isolation device is designed to reduce the seismic force acting on the building.

Effects of the Invention This invention has the following effects because it has the above configuration.

Since there are no columns or beams and it consists only of walls and floor slabs, the walls and floor slabs can be constructed using large formwork with simple shapes, simplifying and speeding up the formwork work, and significantly reducing costs. You can aim for down.

By staggering the concrete for the boundary walls, buttresses, and floor slabs between each dwelling unit and placing them separately, it is possible to achieve the optimum concrete strength and slump depending on the area. This also eliminates waste in concrete mixing,
Materials can be saved.

In addition, the entire building is supported by a seismic isolation device to prevent it from being directly affected by a major earthquake, and buttresses are placed on the sides of the walls between each unit, and the walls and buttresses are seismically resistant. It is constructed as a wall to ensure sufficient earthquake resistance, and the floor slab on each floor is made into a large slab by inserting unbonded PC steel wires, so even though it is a so-called wall-type structure, it has the maximum frontage on the surface that is in contact with the outside air. It is possible to secure a limited opening. Moreover, since the columns and beams do not protrude into the room, planar planning can be carried out freely without any restrictions.
