Multilevel multi-curve single-layer welding ball steel structure net rack and construction method thereof

Abstract

Disclosed is a multilevel multi-curve single-layer welding ball steel structure net rack. Each layer of the multilevel multi-curve single-layer welding ball steel structure net rack comprises a structurally separated rod and a hollow ball which are connected into a whole in a welded manner; an elastic support positioned on a reinforced concrete vertical column is connected with each layer of the multilevel multi-curve single-layer welding ball steel structure net rack through a net rack supporting part; the elastic support is capable of inching in a certain direction or an optional direction, and the net rack further comprises a cable-supported structure consisting of a cable-supported structure support, a cable-supported ball, a pull cable and a cable-supported ball supporting rod. The net rack is unique in appearance and suitable for serving as a building steel structure support which has high requirements on the appearance of a building, is unique in appearance and needs to display arc shapes, line shapes, shell shapes and staggered levels, and the construction method of the net rack can be used for effectively controlling space coordinates and positional accuracy of components of the net rack, structural stability and structural appearance diversity of the net rack during installation, so that the requirements of a building structure on high, large, difficult and multidirectional change can be met.

Description

technical field [0001] The invention relates to a construction method of a multi-level multi-curved single-layer welded space steel structure grid and a multi-level multi-curved single-layer welded spherical steel structure grid, in particular to a construction method for large-span, multi-curved, multi-level, single The utility model relates to a multi-level multi-curved surface single-layer welded spherical steel structure grid of layered shell type space grid and a construction method thereof. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, in order to meet the needs of social development and enrich people's cultural and sports life, cities have increased the construction of large steel structure venues such as gymnasiums, theaters, exhibition halls, and science and technology museums; The roofs of these long-span buildings mostly adopt steel reticulated shell structures, especially the multi...

[0002] In recent years, with the development of society and the improvement of people's living standards, in order to meet the needs of social development and enrich people's cultural and sports life, cities have increased the construction of large steel structure venues such as gymnasiums, theaters, exhibition halls, and science and technology museums; The roofs of these long-span buildings mostly adopt steel reticulated shell structures, especially the multi-layered and multi-curved spatially shaped multi-curved reticulated shells; At the same time, the amount of steel used is less, it has good economy, and it has unique adaptability to various shapes of large-span building roofs, but the traditional steel structure grid can no longer meet the requirements of arbitrary curved surfaces, multiple layers, and shapes. Diversity, and the planning of large-scale buildings require space use, rational distribution of the force of each component of the steel structure, and the artistic effect of the building shape. The construction method of multi-level multi-curved single-layer shell-type space grid is a difficult problem for builders
