Embodiment Construction

[0039] Attached to the following Figure 1-6 This application will be described in further detail.

[0040] The embodiment of the present application discloses a large-span steel structure with an inclined column truss cable. refer to figure 1, a large-span steel structure of inclined column truss cable includes inclined column system 1 , outer ring suspension cable roof system 2 and inner ring chord support roof system 3 . The inner ring chord roof system 3, the outer ring suspension cable roof system 2 and the inclined column system 1 are arranged concentrically, the inner ring chord roof system 3 is arranged in the center, and the outer ring suspension roof system 2 is arranged in the middle of the connection , the inclined column system 1 is set outside.

[0041] refer to figure 1 and 2 , the inner ring chord roof system 3 includes a central funnel mechanism 31 arranged at a central position and a chord roof mechanism 32 connected to the periphery of the central funne...

Abstract

The invention relates to the technical field of large-span space buildings in civil engineering, in particular to an inclined column truss inhaul cable large-span steel structure which comprises an inclined column system, an outer ring suspension cable roof system and an inner ring chord support roof system which are sequentially arranged from inside to outside. The inner ring suspended roof system, the outer ring suspended cable roof system and the inclined column system are concentrically arranged, the inner ring suspended roof system is fixedly connected with an inner ring of the outer ring suspended cable roof system, and an outer ring of the outer ring suspended cable roof system is fixedly connected with the inclined column system. When the batter post system is stressed, the batter post system further tends to stretch the outer ring suspension cable roof system, so that the outer ring suspension cable roof system has an expansion trend, the batter post system and the outer ring suspension cable roof system are matched with each other, internal force borne by the outer ring suspension cable roof system and vertical shearing force of a central part are reduced, and the service life of the outer ring suspension cable roof system is prolonged. The roof system has the effects that deformation of the roof system can be controlled easily, and the bearing capacity of the roof system is improved.

Description

technical field [0001] The invention relates to the technical field of large-span space buildings in civil engineering, in particular to a large-span steel structure with inclined column truss cables. Background technique [0002] In the spatial structure design of sports and cultural large-span buildings, long-span steel structures are often used. Generally, steel structures with a horizontal span of 60 meters, concrete with a span of more than 30 meters, and frame structures with a span of more than 18 meters are large-span steel structures. Its structural forms mainly include five spatial structures and various combined spatial structures such as grid structure, reticulated shell structure, suspension cable structure, membrane structure, and thin shell structure. [0003] When the large-span steel structure in the current architectural design bears a large load, the large-span steel structure is deformed by the force, which causes harmful internal forces inside the steel...
