Abstract

The invention discloses a method for overall hoisting of a large-span spherical grid frame. The invention adopts a combination of overall hoisting and segmental hoisting to hoist a large-span spherical grid frame. Overall assembly, the reserved value of the arching height is prepared during the assembly process, and the upper grid frame is lifted and installed as a whole through multiple lifting equipment, and the upper structure of the overall hoisting is used to form an operation platform, and the lower structure is assembled in sections , hoisting and connecting in sections to form a whole, which reduces the bulk of components at high altitudes, reduces the amount of scaffolding, and reduces the amount of high-altitude operations. The construction is safe and reliable, reduces construction risks, improves construction work efficiency, and is conducive to the quality control and maintenance of grid structures. Safety production control.

Description

technical field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an integral hoisting method of a large-span spherical grid frame. Background technique

[0002] With the continuous and innovative rapid development of the construction industry, people's requirements for buildings are not limited to functionality, usability, and economy, but more pursuit of unique appearance requirements, reflecting the trend of the new era, and building characteristics. Among them, the large-span space spherical grid frame is favored by the modern construction industry for its light weight, high rigidity, large span, flexible layout, beautiful appearance, and generous features.

[0003] At present, the installation method of the large-span space spherical grid is: first assemble and weld the small units, and then lift the small units to the preparation site for high-altitude assembly, and perform high-altitude assembly and welding from...
