Cable dome and installation method thereof

Abstract

The invention mainly discloses a cable dome and its installation method. The ring cable connected by the oblique cable; during installation, a central pressure ring is set up to assemble the tire frame, and two inner and outer cable laying platforms are set up to lay the notochord and oblique cables; the upper ring of the central pressure ring is connected to the inner notch cable, and the inner notch cable, The connecting node of the middle ridge cable is connected with the inner strut and the inner cable, and at the same time, the lower ring of the central pressure ring is connected with the inner cable, the inner strut is connected with the middle cable, and the connecting node of the inner strut and the middle cable is passed through the inner Ring cable connection; apply traction force to raise the structure to a certain height, complete the assembly until the traction and tensioning of the cable dome is completed. The invention not only reduces the workload of high-altitude assembly of the cable system and ensures construction safety, but also performs overall assembly of the cable system on the ground, and then carries out high-altitude lifting and tensioning to ensure the final forming state of the structure.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a cable dome and an installation method thereof. Background technique [0002] Cable dome technology is the highest achievement of space structure technology in the modern world, based on the concept of TENSEGRITY of the famous American architect Mr. Fuller. The stiffness of this structure is provided by the balanced pretension between the tension and compression units. Before the pretension is applied, the system has almost no stiffness, and the magnitude of the initial pretension plays a decisive role in the shape of the system and the stiffness of the structure. Because the tensegrity structural system inherently complies with the laws of nature, and maximizes the use of the characteristics of materials and sections, it is possible to use a small amount of materials to build super-long-span buildings. At present, foreign developed regions have successfully a...

Problems solved by technology

With such an installation method, high-altitude operations are labor-intensive and the force balance of the overall structure is poor. Therefore, the applicant aimed at the gap in the installation technology of large-scale cable domes in China, and developed a new design and development of a cable dome and its installation method. This case resulting from
