Rigid roof cable-dome structure with circumferential-direction support

Abstract

The invention discloses a rigid roof cable-dome structure with a circumferential-direction support. The rigid roof cable-dome structure comprises an internal pull ring and an external ring, at least one round of circumferential-direction assembly is arranged between the internal pull ring and the external ring, and the circumferential-direction assembly separates the part between the internal pull ring and the external ring into at least two stages of structures; a plurality of ridge cables arranged in a radial shape in the radial direction are arranged between the internal pull ring and the external ring, one ends of the ridge cables are connected with the internal pull ring, the other ends of the ridge cables are connected with supporting points of the external ring, and the middle of each ridge cable is connected with the upper end portion of the corresponding circumferential-direction assembly; and oblique cables are arranged between the circumferential-direction assembly and the external ring as well as between the circumferential-direction assembly and the internal pull ring correspondingly, if multiple rounds of circumferential-direction assemblies are arranged, oblique cables are arranged between the every two adjacent circumferential-direction assemblies, and the oblique cables are arranged in a radial shape in the radial direction. According to the rigid roof cable-dome structure with the circumferential-direction support, force transferring is direct, the high-strength character of an inhaul cable is brought into full play, the rigid roof cable-dome structure has the advantages of being good in rigidity, good in stability, simple in structure, rapid in construction and the like, meanwhile a rigid roof technology adopted by the rigid roof cable-dome structure is mature, and the cost is relatively low.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a rigid roof cable dome structure with hoop support that can be applied to large-span buildings such as gymnasiums and exhibition halls. Background technique [0002] The cable dome structure is a tension structure proposed by American engineer Geiger based on Fuller's tension overall structure idea. As early as the 1940s, Fuller believed that the operation of the universe was carried out according to the principle of tensegrity, so he imagined that a truly efficient structural system should be a self-balancing system of pressure and tension. In 1984, his student, the sculptor Snelson, completed the first tensegrity model, based on which he designed urban sculptures, which proved Fuller's vision and was recognized as a starting point for the development of modern tensegrity structures. Fuller was more encouraged and inspired by this, and published th...

Problems solved by technology

[0004] Although the cable dome structure has been developed rapidly in foreign countries, its development in my country is relatively lagging behind. On the one hand, it is due to its technical difficulty. Although the material has the advantages of good permeability, it limits the form of the building, is sensitive to wind loads, has high environmental requirements, cannot hang other loads at will, and is expensive, which reduces the scope of application of the cable dome
