Jacking method and device of steel structure module

Abstract

The invention discloses a jacking method and a jacking device of a steel structure module, and belongs to the technical field of structure module jacking. The jacking method of the steel structure module is characterized in that the sufficient number of hydraulic jacks are arranged according to the size of the steel structure module, a jacking framework platform and a foundation box are placed on the hydraulic jacks, when the hydraulic jacks are in a jacking state, standard joint pad blocks are inserted in two side positions between the foundation box and the jacking framework platform, when the hydraulic jacks are in a falling-back state, loads are transferred onto the standard joint pad blocks, standard joint inserting blocks are inserted between the standard joint pad blocks, the processes of hydraulic jack jacking, standard joint pad block insertion, hydraulic jack falling-back and standard joint inserting block insertion are repeated, and in addition, the adjacent upper and lower layers of standard joint pad blocks form 90-degree crossing until the steel structure module is jacked to the set position. The jacking method and the jacking device have the advantages that the requirements on the fields are low, the received jacking force of the steel structure module is uniform, the deformation cannot easily occur, the jacking process operation is simple and convenient, and a large amount of work can be reduced.

Description

technical field [0001] The invention relates to a jacking method and device for a steel structure module, which belongs to the technical field of structural module jacking, in particular to the technical field of modular jacking, transportation and installation of large-scale engineering steel structures. Background technique [0002] During the transportation and installation process of large-scale steel structure modularization, in order to meet the requirements of the base elevation of the module installation, the large-scale structural modules need to carry out the operation of raising the module elevation, and the weight of the modules is generally relatively heavy. At present, the overall lifting method of domestic steel structures often adopts the overall lifting method or the overall hoisting method of a large crane. The lifting method is widely used in the field of large-scale equipment hoisting. When it is used in the field of structural modules, columns are instal...

AI Technical Summary

Problems solved by technology

The lifting method is widely used in the field of large-scale equipment hoisting. When it is used in the field of structural modules, columns are installed on both sides of the module structure, and the steel structure module moves upwards as a whole through lifting. The disadvantage of this lifting method is high cost and few lifting points. , it is very easy to cause the overall structural deformation of the module, resulting in damage to the module structure

The large-scale crane hoisting method is to set multiple hoisting points on the top of the steel structure module and use the frame-type balance beam for hoisting. This method has the following disadvantages: high requirements for the site, high risk of hoisting, heavy welding workload on the top of the steel structure, and heavy hoisting. Uneven force can easily lead to deformation of the module structure
