Problems solved by technology

[0002] The connection between the long-span grid structure and the concrete column usually adopts spherical joint bearings. After the overall lifting of the long-span steel structure grid structure is completed, the grid structure needs to be unloaded. During the lifting process, the concrete column as the lifting point is prone to Larger displacement, in related technologies, it is usually used to build a temporary support tire frame, and set an adjustable support device on the temporary support tire frame, such as an hourglass device, to generate displacement in the unloading direction, so as to facilitate the unloading of the steel structure, and Remove the temporary support tire frame and hourglass device after unloading is completed. This unloading method is only suitable for temporary support systems with a large number of fixed-point supports, and cannot solve the problem of deformation recovery of concrete columns after lifting

Abstract

The invention discloses an unloading method and unloading device for a spherical hinge support of a grid structure. The unloading method and unloading device are used for deformation recovery of a concrete column. An embedded part and the spherical hinge support are arranged on the top of the concrete column, a sliding plate is placed between the embedded part and the spherical hinge support, lifting force on the grid structure is released, the grid structure is unloaded to the spherical hinge support, and the spherical hinge support is fixed to the column top of the concrete column. According to the unloading method and the unloading device for the spherical hinge support of the grid structure, the sliding plate is arranged between the embedded part at the top of the concrete column and the spherical hinge support, so that the friction force between the embedded part and the spherical hinge support is reduced, and the spherical hinge support can slide relative to the embedded part in the lifting force unloading process of the grid structure; therefore, deformation of the concrete column is recovered, the unloading precision of the grid structure is improved, and the supporting strength of the concrete column to the grid structure is improved.
