Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as Figure 1-6 As shown, a strip-shaped steel tie plate cable dome structure includes a strip steel tie plate 1, oblique cables 2, struts 3, ring cables 4, a central inner ring beam 5 and a peripheral outer ring beam 6. One end of the steel tie plate 1 is connected to the central inner ring beam 5, and the other end is connected to the peripheral outer ring beam 6 through the end node 7, and the upper ends of the oblique cables 2 and the struts 3 are connected to the strip steel tie plate through the connecting node 8 1 connection, the oblique cable 2 connects the upper end and the lower end of the adjacent ring strut 3, and the ring cable 4 connects the lower end of the same ring strut 3, and is closed along the ring direction, and is stretched on the strip steel by prestressing Establish prestress in plate 1, oblique cable 2, and ring cable 4 to form a f...

The invention discloses a strip-shaped steel pulling plate cable dome structure which comprises strip-shaped steel pulling plates, inclined cables, support bars, hoop cables, a center inner ring beam and peripheral outer ring beams; one ends of the strip-shaped steel pulling plates are connected with the center inner ring beam, and the other ends of the strip-shaped steel pulling plates are connected with the peripheral outer ring beams through end nodes; the upper end of each inclined cable and the upper end of each support bar are connected with the corresponding strip-shaped steel pulling plate through a connecting node, the inclined cables connect the upper ends with the lower ends of the corresponding support bards of adjacent rings, each hoop cable connects the lower ends of the support bars of the same ring and are closed in the ring direction, prestress is established among the strip-shaped steel pulling plates, the inclined cables and the hoop cables through prestress tension, and a full-tension structure with certain rigidity is formed. According to the strip-shaped steel pulling plate cable dome structure, inhaul cables are replaced with hot-rolled steel sheet strips, the use amount of cable clamps is decreased, and the structure construction cost is effectively reduced; structure nodes can be connected through bolts, upper rigid roofing materials are easy to install, and construction is easy, convenient and rapid.
Description
technical field [0001] The invention relates to the technical field of space structures of civil engineering, in particular to a dome structure of strip-shaped steel stay cables. Background technique [0002] The cable dome structure has the advantages of large span, light weight, full use of high-strength materials, material saving, high degree of on-site assembly, fast construction speed and environmental protection, and is widely used in long-span spatial structures. Compared with flexible roofing materials such as membrane materials, conventional rigid roofing materials have the advantages of reasonable structural stress, convenient roof insulation, strong pollution resistance, simple construction and low cost, and their application in flexible structures has huge economic benefits. However, when the rigid roof panel is applied to the conventional cable structure, the connection between the cable body and the rigid roof requires special structural connection measures. Du...
