Description
Technical Field
[0001] The utility model relates to the technical field of civil engineering, in particular to a combined beam-string secondary arch structure with a single cable and double beams. Background Art
[0002] The combined beam string secondary arch structure of single cable and double beam is an advanced building structure, which combines the high efficiency of beam string and the stability of secondary arch. Beam string, as a rigid-flexible hybrid structure, is composed of rigid components of upper chord and high-strength tensioned cable rods, which are connected by several struts. It uses form resistance and pre-tension to resist external loads and has the characteristics of efficient large-span spatial structural system. As for its evolution process, it can be traced back to the cast iron bridge in the early 19th century and the later tension arch, King Post truss, self-anchored suspension bridge and other structural forms.
[0003] The combined design of single cable and double beams also increases the lightness of the structure. By using high-strength materials, such as high-performance steel, the material usage is reduced while ensuring the structural strength, thereby reducing the self-weight of the entire structure. This is not only conducive to reducing construction costs, but also helps to improve the energy-saving performance of the building. At the same time, this structure also has good construction convenience. Its structural form and construction method are relatively simple. It is constructed by prefabrication and assembly, thereby shortening the construction period and improving construction efficiency. At the same time, due to the high stability and rigidity of the structure, it also reduces safety risks during construction.
[0004] Most of the existing technologies require at least two beam string structures to form a floor (roof) panel plane on the upper chord, which requires two cables, increasing material consumption. A single beam string structure cannot withstand vertical ground loads, so at least two beam string structures are required. The two beam string structures are subjected to force independently and cannot assist each other. A single beam string structure has only one support at both ends, so its torsional (anti-overturning) capacity is poor. In view of this, we propose a combined beam string secondary arch structure with a single cable and double beams. Utility Model Content
