Problems solved by technology

Obviously, only changing the grid type of the steel grid tube and the structural type of the concrete core tube cannot effectively improve the vertical bearing capacity of the steel grid tube, and the design economy is also poor. Therefore, it should be considered to improve the structure shape and structure. Looking for solutions in the system

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with accompanying drawings 1 to 3 .

[0026] As shown in Figures 1 to 3, a hybrid structure composed of a steel grid tube, a core tube and a radially flexible cable tray includes the following components:

[0027] 1——steel grid cylinder, including two types: 1-1—cylindrical grid cylinder, 1-2—hyperboloid grid cylinder;

[0028] 2 - core tube;

[0029] 3——Prestressed cable;

[0030] As shown in Figure 2, the hybrid structure includes a steel grid tube 1, a core tube 2 and a prestressed cable 3; one end of the prestressed cable 3 is connected to the steel grid tube 1, and the other end is connected to the core tube 2 The connection plays the role of connecting the steel grid tube 1 and the core tube 2 so that they can receive force together.

[0031] As shown in FIG. 1 , the steel grid cylinder 1 includes two types of cylindrical grid cylinder 1-1 and hyperboloid grid cylinder 1-2.

Abstract

The invention relates to a combined structure composed of a steel grid barrel, a core barrel and a radial flexible cable tray and belongs to the technical field of structure engineering.A radial prestress inhaul cable is arranged between a traditional steel grid barrel and the concrete core barrel to form the combined structure, the aim of improving vertical bearing force of the peripheral steel grid barrel is achieved, and accordingly a more stable spatial structure system is formed.By means of the arrangement of the space radiation type flexible cable, it is guaranteed that a transparent building effect is formed between the steel grid barrel and the concrete core barrel.By means of the out-of-plane constraint function of the flexible cable on the steel grid barrel, out-of-plane local deformation of barrel components is effectively restrained, defect sensitivity of the steel grid barrel is reduced, and accordingly multi-column unstability damage is effectively prevented.The flexible cable tray can guarantee that the core barrel and the peripheral steel grid barrel are stressed synergistically, the requirement for strength and rigidity of the core barrel and the steel grid barrel is reduced, and economical efficiency of structural design is remarkably improved.

Description

technical field [0001] The invention relates to a hybrid steel structure, in particular to a hybrid structure composed of a steel grid tube, a core tube and a radially flexible cable tray, belonging to the technical field of structural engineering. Background technique [0002] As a vertical load-bearing structure, there are more and more engineering applications of steel grid tube + concrete core tube structure. The most typical engineering applications are the China Animation Museum and the Guangzhou New TV Tower. The former uses a hyperbolic diamond-shaped steel grid tube, while the latter uses a triangular steel grid tube with obvious differences in stiffness directions. The built-in core tube provides lateral resistance. Force stiffness and vertical traffic passages such as elevators. [0003] For the above-mentioned steel grid tube + concrete core tube, the peripheral steel grid tube can usually adopt a cylindrical or hyperboloid type. No matter what type is used, un...
