Unloading method and unloading device for spherical hinge support of grid structure
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.
本发明公开了一种架结构球铰支座卸载方法及卸载装置，用于混凝土柱的变形恢复，混凝土柱的柱顶设置埋件与球铰支座，埋件与球铰支座之间放置滑移板，释放对网架结构的提升力，将网架结构卸载至球铰支座，球铰支座固定于混凝土柱的柱顶。本发明中的网架结构球铰支座卸载方法及卸载装置，通过在混凝土柱柱顶的埋件与球铰支座之间设置滑移板，降低埋件与球铰支座之间的摩擦力，使球铰支座在网架结构提升力卸载的过程中，能够相对埋件滑移，从而使混凝土柱的变形得到恢复，并提高了网架结构的卸载精度，以及混凝土柱对网架结构的支撑强度。
