Embodiment 1

[0030] An ultra-high steel structure with a support frame core tube structure system, such as Figure 1~2 As shown, it includes a plurality of gravity columns 1, gravity beams 2 and supports 3. The gravity beams 2 are arranged on the gravity columns 1 and combined with the gravity columns 1 to form a plurality of cylindrical structures 4. The support 3 is arranged on the cylindrical On the side wall of the structure 4, the gravity column 1 is a steel column or a steel tube concrete column, the gravity beam 2 is a steel beam, and the support 3 is a steel support. The layout of the gravity column 1 is adjusted according to the building requirements, and the distribution is in the shape of a zigzag, and the core tube structure system is retracted sequentially from bottom to top, forming the core tube 5 in the low area, the core tube 6 in the middle area, and the core tube 7 in the high area. The gravity column 1 The number of partitions also decreases sequentially;

Embodiment 2

[0035] An ultra-high steel structure with a support frame core tube structure system, such as Figure 6 As shown, it includes a plurality of gravity columns 1, gravity beams 2 and supports 3. The gravity beams 2 are arranged on the gravity columns 1 and combined with the gravity columns 1 to form a plurality of cylindrical structures 4. The gravity columns 1 are steel columns or steel pipe concrete column, the gravity beam 2 is a steel beam, and the support 3 is a steel support. The layout of the gravity column 1 is adjusted according to the building requirements, and the distribution is in the shape of a nine-square grid, and the core tube structure system is retracted sequentially from bottom to top, forming the core tube 5 in the low area, the core tube 6 in the middle area, and the core tube 7 in the high area. The gravity column 1 The number of partitions also decreases sequentially;

[0036] The gravity column 1 is distributed in a nine-square grid pattern, and the cyli...

Embodiment 3

[0040] This embodiment is basically the same as Embodiment 1, the difference is that the core tube structure system of this embodiment is also connected to the external giant columns arranged outside the core tube structure system through outriggers. The outrigger includes a built-in outrigger and an outrigger. The built-in outrigger is formed by the gravity beam 2 located at the reinforcement layer or the refuge layer, and the built-in outrigger is connected to the external giant column through the outrigger.

[0041] This implementation has the advantages of light structure weight, good wind resistance and earthquake resistance, flexible building layout, fast construction speed, high degree of construction industrialization, and less wet work on site. The size of the column section is reduced, the layout of the structural building is flexible, and the structural components have little impact on the building function.

Abstract

The invention relates to an ultra-high-steel-structured core tube structure system with a supporting frame. The ultra-high-steel-structured core tube structure system with the supporting frame comprises a plurality of gravity columns, gravity beams and a support, wherein the gravity beams are arranged on the gravity columns and are combined with the gravity columns to form a plurality of cylindrical structures; the gravity columns are steel columns or steel tube concrete columns; the gravity beams are steel beams; and the support is a steel support. Compared with the prior art, the steel structure system has the advantages of light structural dead weight, good wind resistance and anti-seismic property, flexible building arrangement, high construction speed, high construction industrial degree, less field wet operation and the like.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to an ultra-high steel structure with a support frame core tube structure system. Background technique [0002] At present, the most widely used super high-rise structure system is the frame-core tube structure. The core tube is in the central part of the building. The central core tube is formed by elevator shafts, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms. , forming an outer frame and inner tube structure with the peripheral frame, which is the mainstream structural form widely used in super high-rise buildings in the world. In the structure above 500 meters, the core tube material is reinforced concrete or a mixture of steel and reinforced concrete and composite components. This kind of structure is self-heavy, and in order to improve the structural performance, the self-weight of the structure must be increased....
