Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building structure of a middle- and high-rise apartment house in which a plurality of dwelling units are integrated in one building such as a condominium.

[0002]

2. Description of the Related Art In a middle-high-rise condominium in which a plurality of dwelling units are gathered in one building such as an apartment, a common corridor, generally called a corridor, is placed in the center of each floor and surrounds the common corridor. The structure of arranging the dwelling units is adopted. In such an apartment house, there is an advantage that the layout of the boundary walls of the dwelling unit can be changed for each floor and the layout can be freely set. In an apartment like this,
Since a partition wall such as a boundary wall of a dwelling unit runs geese over the upper and lower floors, a ramen structure constructed by rigidly connecting columns and beams has been generally adopted as a structural form of a building.

[0003]

However, in an apartment house adopting this ramen structure, the size of columns and beams becomes large, which causes a rise in floor height, and the beam width of the girder is large, so that the unit Since the bus cannot be brought close to the wall, there is a problem that a lot of useless space is generated. In addition, since the pillars and beams project into the living space of the dwelling unit, the habitability is impaired and the space cannot be effectively used. In addition, a girder must be provided with a sleeve for exhausting water around the bathroom, kitchen, toilet, washroom, etc., and this requires measures such as extra reinforcement bars placed around the sleeve. However, the cost was increased.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent columns and beams from protruding into a living space, to create a useless space, and to effectively utilize the space. It is to provide a building structure of a high-rise apartment house that can be.

[0005]

[Means for Solving the Problems] In order to achieve such an object, in a building structure of a middle and high-rise apartment house according to the present invention, a common corridor and an elevator installation zone arranged at the center of each floor of the building, Lower floors of the building are equipped with earthquake-resistant walls that surround shared areas such as elevator halls and staircase zones, entrance zones of each dwelling unit, and water supply zones such as bathrooms, kitchens, washrooms, and toilets of each dwelling unit. From the earthquake-resistant core tube to the upper floors, and the pillars constructed to surround the outside of this earthquake-resistant core tube.
An outer frame composed of beams, and a slab installed between the outer frame and the seismic resistant core tube to construct a floor of each floor of the building (claim 1).

The inventor of the present invention, in an apartment house in which the dwelling units are arranged so as to surround the common corridor as described above, shortens the pipe length from the common pipe to reduce the head, and reduces the height of the pipe space. Therefore, focusing on the fact that the water supply zones such as bathrooms, kitchens, washrooms, and toilets are generally located near shared corridors, and constructing an earthquake-resistant core tube to surround these zones, the ramen structure I thought that other structural formats could be adopted. Therefore, we devised the building structure.

In this building structure, the seismic resistant core tube is
Common zones such as shared corridors, elevator installation zones, elevator halls, stair zones located in the center of each floor of the building, entrance zones for each dwelling unit, and bathrooms, kitchens, washrooms, toilets, etc. around each dwelling unit Since it is constructed so as to surround the zone, it is possible to secure a large cross-sectional area of the seismic resistant core tube, which ensures sufficient rigidity even when the wall thickness is thin.

In this building structure, since there is no need for large columns or beams, there is no need to raise the floor height, and there is no protrusion of columns or beams into the living space, which does not impair livability. The space can be effectively used as well. In addition, since the seismic-resistant core tube can have a structure without studs or beams, the unit bath can be moved up to the wall side, thereby avoiding wasting space. Furthermore, as mentioned above, seismic resistant core tubes are used in common areas such as common corridors, elevator-related zones, staircase zones, entrance zones for each dwelling unit, and water supply zones such as bathrooms, kitchens, washrooms, and toilets for each dwelling unit. Since it surrounds, it is possible to secure a large cross-sectional area, which makes it possible to sufficiently apply it to a small building. Further, since the seismic core tube blocks the water supply zone and the living room zone, a high sound insulation effect can be obtained.

Further, in the building structure of the middle-high-rise apartment house, the earthquake-resistant core tube is made of a reinforced concrete structure (claim 2). In this way, by making the earthquake-resistant core tube a reinforced concrete structure, sufficient rigidity can be secured.

Further, in the building structure of the middle-high-rise apartment house, the partition wall for partitioning the space portion in the earthquake-resistant core tube is formed by the earthquake-resistant wall integrally provided on the inner peripheral portion of the earthquake-resistant core tube. It is constructed (claim 3). By constructing the partition wall inside the seismic resistant core tube with seismic resistant walls in this way, the space inside the seismic resistant core tube can be made into a space without studs or crossbeams. Can be utilized.

Further, in the building structure of the middle-high-rise apartment house, the slab is constituted by a slab with a beam or a flat slab (claim 4). Since the slab is composed of the slab with beam girders or the flat slab in this way, the space between the seismic resistant core tube and the outer perimeter frame can be a space without girders. It can be effectively used.
