Problems solved by technology

[0003] The conventional long-span steel structure in related architectural design has the problems of poor overall rigidity performance and difficult structural deformation control, and the long-span steel structure often adopts the way of setting temporary support columns before the overall structure reaches the design stress state. Due to the gravity of a part of the span steel structure, the removal of the temporary support column after the construction is completed will easily cause secondary deformation, which will easily cause harmful internal forces to the existing structure and affect the service life of the long-span steel structure building

Embodiment Construction

[0044] Attached to the following Figure 1-3 This application will be described in further detail.

[0045] The embodiment of the present application discloses a large-span steel structure with a double-ring cable, refer to figure 1 , The double-ring cable long-span steel structure includes an inner ring steel structure system 1, a cable connecting structure system 2 between the inner and outer rings, and an outer ring steel structure system 3, which are arranged sequentially from the center to the circumferential edge. The inner ring end of the cable connection structure system 2 between the inner and outer rings is connected to the inner ring steel structure system 1 , and the outer ring end of the cable connection structure system 2 between the inner and outer rings is connected to the outer ring steel structure system 3 . The inner ring steel structure system 1 and the cable connection structure system 2 between the inner and outer rings are both suspended, and the outer ri...

Abstract

The invention relates to the technical field of large-span space buildings, in particular to a double-ring inhaul cable large-span steel structure which comprises an inner ring steel structure system, an inhaul cable connecting structure system between an inner ring and an outer ring and an outer ring steel structure system. The inhaul cable connecting structure system between the inner ring and the outer ring is connected with the inner ring steel structure system and the outer ring steel structure system. The outer ring steel structure system can abut against the ground to support the inner ring steel structure system and the inner and outer ring inhaul cable connecting structure system. The inhaul cable connecting structure system between the inner ring and the outer ring comprises a plurality of three-dimensional fan-shaped units which are connected with one another, each fan-shaped unit comprises at least one bearing cable, and the two ends of each bearing cable are connected with the inner ring steel structure system and the outer ring steel structure system correspondingly. Structural deformation of the large-span steel structure is effectively controlled, and after the temporary supporting columns are dismantled, the probability of secondary deformation of the large-span steel structure is reduced, and the possibility that an existing structure part generates harmful internal force is reduced.

Description

technical field [0001] The present application relates to the technical field of large-span space buildings, in particular to a large-span steel structure with double-ring cables. Background technique [0002] In the spatial structure design of large-span stadium buildings such as stadiums and cultural theaters, long-span steel structures are often used. [0003] The conventional long-span steel structure in related architectural design has the problems of poor overall stiffness performance and difficult structural deformation control, and the long-span steel structure often adopts the method of setting temporary support columns before the overall structure reaches the designed stress state. Due to the gravity of a part of the span steel structure, the removal of the temporary support column after the construction is completed will easily cause secondary deformation, which will easily cause harmful internal forces to the existing structural parts and affect the service life ...
