DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to form pillars in a living room part by positively arranging a structural core which is a main part of a structural body in a so-called dead space around an elevator shaft or a staircase. The present invention relates to a structure of a building in which a large room with no pillars is secured by reducing as much as possible and a floor plan can be freely set.

[0002]

2. Description of the Related Art In a building having a so-called ramen structure, many columns and beams are arranged around an elevator shaft and a staircase, so that a space that can be used as a living room cannot be secured. In addition, many walls are arranged around the elevator shaft and the staircase to partition the elevator shaft and the staircase, and the wall often forms a part of the structure.

[0003] However, many of the walls in this part are thinner than columns or beam widths, resulting in wasted space.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has a structure in which a structure core, which is a main part of a structure, is intensively arranged in a surrounding dead space such as an elevator shaft or a staircase. It is an object of the present invention to provide a building structure in which the pillars in the living room portion are reduced as much as possible to secure a large living room space and a free plan can be made.

[0005] The structure of a building according to the present invention can be used in a building.
In the center or end, such as elevator shafts, staircases, etc.
Common facilities and facilities such as air-conditioning machine rooms and duct spaces
To be located around the common facilities and equipment facilities.
The structural core that forms the main part is placed around the building around the building.
Pillars forming a structure of the structure core and the pillars further
Arrange the large burrs between the upper ends, and
A damper that absorbs the difference in vibration period between a column and a large beam in the gap
The above-mentioned object is achieved by installing a key.

[0006]

In the structure of a building according to the present invention, the structure cores and columns arranged around a common facility such as a staircase room, equipment facilities such as an air-conditioning machine room, and the periphery of the building are the main parts of the building structure. Therefore, the number of pillars in the room can be greatly reduced.

For this reason, a large living room without pillars can be secured on each floor, a free plane plan can be made without restriction of pillars, and a large opening can be obtained by enlarging the surrounding pillar span. be able to.

[0008]

1 and 2 show the structure of a building according to the present invention.
1 shows an embodiment of a body , in which figures 1, 2 and 3 are located in the center of a building and are used as elevator shafts, elevator halls and staircases used as shared facilities;
Reference numerals 4, 5, and 6 denote an air-conditioning machine room, a duct space, and a pipe space which are arranged in the center of the building and used as facility facilities.

Reference numeral 7 denotes a structural core which is disposed around these common facilities and facility facilities, and forms a main part of the structural body. Reference numeral 8 denotes a pillar which is disposed around the building and forms a structural body around the building. Reference numerals 9 and 9 denote large beams which are provided between the upper end of the structural core 7 and the upper ends of the surrounding columns 8 and join the upper end of the structural core 7 and the upper ends of the columns 8 respectively.

Further, reference numeral 10 denotes a damper which is provided between the large beam 9 and each column 8 and absorbs a difference in vibration period between the column 8 and the large beam 9. It is a floor slab that is arranged in a plurality of layers between each pillar 8 and serves as a floor of each floor.

The structural core 7 is constructed of reinforced concrete or steel-framed reinforced concrete, and is designed to bear the weight of the floor slab 11 on each floor, the loaded load, and a large seismic load. It is constructed to have a certain amount or more of wall amount (wall length) in each of the X and Y directions.

The shape and position of the structural body core 7 are as follows.
The shape is not necessarily limited to the illustrated shape as long as a certain amount or more of the wall amount is secured in each of the X and Y directions, and may be, for example, a cylindrical shape.

Further, the planar shape and arrangement of the structural core 7 are determined by the arrangement of common facilities such as the elevator shaft 1 and the elevator hall 2 and the facilities such as the air conditioning machine room 4 (FIGS. 3 to 3). See FIG. 6).

The pillars 8 are designed to mainly bear the load of the tip of the floor slab 11 on each floor, are arranged around the building at arbitrary spans according to the plan of each floor, and if necessary, A small pillar 8a is arranged between 8,8.

Since the vibration period of the column 8 and the large beam 9 is different, the damper 10 is installed to prevent the upper end of the column from being destroyed during an earthquake or the like. For example, a hydraulic damper, a plastic damper, etc. Is used.

The floor slab 11 is designed to simply transmit the load of a person or furniture to the structural core 7 and the surrounding columns 8, and is designed to have a thickness of about 30 cm.

At the time of construction, the large burrs 9 are first constructed on the ground, and then the structure core 7 and the surrounding pillars 8 are constructed.
If the floor slabs 11 of the respective floors are sequentially constructed in the upper floor direction, the large burrs 9 can be used as a hut combination of all-weather temporary roofs.

[0018]

The present invention has the above-described structure,
The structure cores and pillars located around the common facilities such as stair rooms, equipment facilities such as air conditioner rooms, and around the buildings constitute the main part of the building structure, so the pillars in the living room can be significantly reduced. It is possible to secure a large living room without pillars on each floor, and a free plan can be made without restriction of pillars, and a large opening can be obtained by enlarging the surrounding pillar span. There are effects such as being able to do.
