Description

[0002] With the rapid development of the battery industry, the construction demand of the battery factory is increasing. The production space of the battery factory usually needs to meet the requirements of large span, high space utilization rate, good ventilation and lighting, etc. The traditional building structure form, such as ordinary steel frame structure or simple truss structure, can meet these requirements to some extent, but there are deficiencies in structural efficiency, material utilization and construction convenience, etc.

[0003] The hyperstatic ring truss structure can effectively disperse the load due to its excess constraint, has small structural deformation, strong rigidity, small cross-section size, light self-weight, and good resistance to damage. This structure performs well in large-span space structure, can effectively reduce the structural self-weight, and improve the overall stability.

[0004] The sunflower three bracing rod II type cable dome structure is a new type of cable dome structure. It abandons the traditional "cable ocean and compression rod island" concept, adopts a layout scheme of 3 bracing rods intersecting, can make one ring cable govern two circles of ridge cables. Under the condition that the number of upper chord grid is unchanged, the number of diagonal cables and ring cables can be reduced by half, thereby improving the convenience of tensioning construction, and improving the stability of local and overall structure. In addition, compared with the traditional cable dome, the structure can effectively reduce the ratio of cables and rods, and has superior technical and economic indicators.

[0005] The combination of hyperstatic ring truss and sunflower three bracing rod II type cable dome applied in the battery factory building not only can meet the demand of large-span space, but also can realize the weight reduction of building roof, column-free inside the building, large-span space, and good seismic and wind resistance performance. This combined structure also has advantages in the construction process, such as reduced construction difficulty and shortened construction period. Therefore, this new combined structure has broad application prospects in the field of battery factory building, and is expected to provide a more efficient, economical and reliable solution for the infrastructure construction of the battery industry.
