Elastic support for single-layer multi-camber steel-structured net rack with single-layer welded balls

Abstract

An elastic support for a single-layer multi-camber steel-structured net rack with single-layer welded balls comprises a support ball, ribbed plates, steel tube brackets, bolts, bevel gears, spring coil cushion plates, spring coils, a bottom plate, transitional plates, stiffening ribs and an embedded plate. the support ball is a hollow steel ball, the bottom plate is a square steel plate, each transitional plate is a square steel plate with borders on four edges, each edge of each transitional plate is longer than each edge of the bottom plate by 8% to 25%, the embedded plate is also a square steel plate, and each edge of the embedded plate is longer than the longest edge of each transitional plate by 10% to 20%. When the elastic support works, the steel tube brackets and the ribbed plates which are used for supporting the support ball are fixed onto the bottom plate, the support ball is fixed onto the steel tube brackets and the ribbed plates, the spring coils, the spring coil cushion plates and the bevel bears are sleeved on the bolts, the bolts penetrate through the bottom plate to be fixed onto the transitional plates, the bottom of the bottom plate is slidably connected with the transitional plates, and the transitional plates are mounted on the embedded plate via the stiffening ribs. The bottom plate of the elastic support has three different structures, so that the elastic support capable of tenderly moving in a certain direction or in an optional direction is formed.

Description

technical field [0001] The invention relates to a multi-level multi-curved surface single-layer welded space steel structure net frame and other parts used in the construction method of a multi-level multi-curved single-layer welded spherical steel structure net frame, especially to a kind of multi-span, multi-curved surface, Multi-level, single-layer shell-type space grid, multi-level, multi-curved surface, single-layer welded spherical steel structure grid, elastic support. 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-layered and multi-cu...

[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 long-span building roofs, but the traditional construction method of steel structure grid can no longer meet the requirements of arbitrary curved surfaces, Due to the diversity of levels and shapes, and the planning of large-scale buildings, the requirements for space use, rational distribution of the force of each component of the steel structure and the artistic effect of the building shape, therefore, a multi-level multi-curved single-layer shell-type space grid roof truss is innovated. The structure and the construction method of the multi-level multi-curved single-layer shell-type space truss roof truss is a difficult problem in front of the builders. Among them, the single-layer multi-curved single-layer multi-curved single-layer welded spherical steel structure grid that supports the multi-layer multi-curved surface Elastic support for welded spherical steel structure grid is an important part
