Description

Large-space office building structure with offset core barrel

Technical Field

With the rapid development of the economy of China, a great number of scientific and technological parks are built around the country. Some scientific and technological parks are convenient for residents to use several floors or a whole building of buildings in the park as office places for meeting the development of small and medium enterprises, and the buildings in the park are generally designed into buildings with smaller volumes.

The number of building layers is not high (the number of building layers is generally 1-8), and the building planes are designed into a large-space office building with a core tube offset. The large-space office building with the offset core barrel is not large in plane size and only has 2-3 spans in the transverse direction, the elevator traffic core, the washroom, the equipment room and the like of the building are arranged in the middle of the north side of the building plane, and the rest parts are used for open type office work. Meanwhile, in order to facilitate indoor lighting and create a good use space, the design of the outer vertical surface of the building is mostly a glass curtain wall or a transparent window,

generally speaking, for the large-space office building with a core barrel with a lower number of floors (the number of floors is 1-4), the reinforced concrete frame structure scheme can meet the requirements of building functions and structural design specifications. However, when the number of the layers exceeds 4, and the core tube of the large-space office building is offset, the whole length adopts a reinforced concrete frame-shear wall structure scheme. For a large-space office building adopting a frame-shear wall structure scheme and with a core tube offset, due to the limitation of the arrangement position of the shear wall, the shear wall needs to be arranged at the corner or the edge of the structure as much as possible, and the lighting requirement cannot be met.

Detailed Description

As shown in fig. 1 and 2, a large-space office building structure with offset core barrels is a 5-8-layer offset core barrel 1 reinforced concrete frame structure, the areas except the core barrel 1 are office areas 3, all the outer vertical surfaces of the office areas 3 of the office building structure are not provided with shear walls, and support columns 4 are arranged at the junction positions of the walls and the strong wall; because the shear wall is omitted, the energy dissipation and shock absorption system 2 needs to be embedded and installed on the wall body of the vertical surface except the office area 3, and the energy dissipation and shock absorption system 2 is at least arranged in the wall body in the two main shaft directions of the main body structure.

If the whole office building structure is not provided with the shear wall, if inside the building, all the outer vertical surfaces are not provided with the energy dissipation and shock absorption system 2. The core tube 1 is arranged at the central position of one side of a large-space office building structure in a biased mode, the energy dissipation and shock absorption systems 2 are arranged in the wall body of the core tube 1, the most ideal state is achieved, and all the energy dissipation and shock absorption systems 2 can be arranged in the wall body of the core tube 1.

However, there are some objective factors, and all the energy dissipation and shock absorption systems 2 cannot be arranged in the wall body of the core tube 1, and can be arranged at the position with the smallest influence on the space use of the office area 3 according to the building or decoration scheme, so as to ensure the lighting effect of the office area 3 as much as possible and improve the actual application area of the office area 3. As shown in fig. 1, the number of the energy dissipation and shock absorption systems 2 is four, two of the four energy dissipation and shock absorption systems are arranged on the wall opposite to the outer vertical surface of the core tube 1, the other one is arranged on the wall adjacent to the outer vertical surface of the core tube 1, the other one is arranged on the wall far away from the outer vertical surface of the office area 3, the four energy dissipation and shock absorption systems 2 are arranged in a zigzag manner, and the wall belonging to the core tube 1 cannot be arranged with all the energy dissipation and shock absorption systems 2.

Wherein, can directly cut a mounting hole on original wall body, form upper cantilever wall A and lower cantilever wall B. If no wall is provided or not enough walls are provided in the office area 3, an upper cantilever wall a and a lower cantilever wall B need to be additionally built. And the last cantilever wall A and the lower cantilever wall B in office area all lean on support column 4 to set up, can let last cantilever wall A and lower cantilever wall B lean on the limit to set up, avoid blocking the road between two parties, improve space utilization, further ensure office area daylighting.
