Cable dome and mounting method thereof

Abstract

The invention mainly discloses a cable dome and a mounting method thereof. The cable dome comprises a central pressure ring, outer ring trusses, a plurality of radial ridge cables, stay cables, supporting rods and annular cables, wherein the radial ridge cables are circumferentially distributed along the central pressure ring with equal angles, the stay cables and the supporting rods are connected to the ridge cables, and the annular cables are connected to the supporting rods and the stay cables. When the cable dome is mounted, a central pressure ring assembling jig frame is set up, an inner cable releasing platform and an outer cable releasing platform are arranged, and the laying of the ridge cables and the laying of the stay cables are carried out. The upper rings of the central pressure ring are connected to inner ridge cables, the connecting nodes of the inner ridge cables and middle ridge cables are connected with inner supporting bars and inner stay cables, the lower rings of the central pressure ring are connected to the inner stay cables, and the inner supporting rods are connected with middle stay cables on the connecting nodes of the inner supporting rods and the middle stay cables through inner annular cables. Traction force is applied to enable the structure to be lifted for a certain height, and integral splicing is carried out until the tensioning and stretching of the cable dome are completed. According to the cable dome and the mounting method thereof, working quantity of high-altitude assembling of cable systems is reduced, construction safety is guaranteed, integral assembling of the cable systems can be carried out on the ground, then high-altitude lifting and tensioning are carried out, and the final forming state of the structure is guaranteed.

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...
