Problems solved by technology

Second, the upper and lower ring beams formed by the rigid support parts of the cable rack steel structure change with the change of the oval structure of the stadium. The space hyperbolic shape formed by them makes all the structural parts change with this change, supporting There is diversity and complexity in the size and size of the components, and the accumulation of structural errors in each unit will cause the entire structure to lose stability, resulting in a great potential safety hazard

Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. The stadium of Wuhan Sports Center has a construction area of ​​80,000 square meters. It has a second-floor stand with a total height of 45 meters, which can accommodate 60,000 spectators. The first-class venue facilities can undertake first-class domestic and international large-scale competitions. The stadium consists of four petal-shaped stands forming an oval platform with a major axis of 277 meters and a minor axis of 245 meters. The stand adopts a frame structure system with four corner tubes. The frame-tube is the support of the canopy. The canopy adopts the current international popular cable-membrane tension structure. Tube-cable-membrane structure system.

[0027] The stadium adopts a cable-membrane tensioned canopy structure, and the steel structure supporting the canopy structure covers an area of ​​27600m 2 ...

Abstract

A construction technology for large overhead cable-steel structure system features that its master rigid supporter is installed by an alternative installation and step interpolation method, which includes such steps as dividing whole engineering into multiple working positions for simultaneous installation, installing the first and then the third rigid supporting units, installing the second unit between the first and the third unit while eliminating the accumulated structural error, repeating said installing steps untile the rigid supporting skeleton system is installed, and installed suspended truss and other accessories. Its advantages are high safety and high structure precision.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to the technical field of construction of a space cable frame steel structure system for large venues. Background technique [0002] Construction is a fast-growing industry, and the development of construction technology is changing with each passing day. More and more large-scale venues, especially sports venues, are designed with the latest concepts and materials, among which the canopy-shaped stadium with cable-membrane tension structure is extremely Rich in the new atmosphere of the 21st century, it makes the gymnasium look novel and beautiful from a bird's-eye view. However, this canopy structure requires a large cable-frame steel structure to support it. Generally, this cable-frame steel structure must be located on large cantilevered reinforced concrete beams and columns, and stadiums generally adopt oval structures. , which brings the fo...
