Example Embodiment

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] see figure 1 , the hoisting method of the high-rise steel structure column of the present invention comprises the following steps:

[0023] Step S1, pre-check the length, section, side bend and elevation of the corbel surface of the steel structure column, report any problems found, and take measures to solve them. At the same time, the elevation and axis of the substructure shall be re-examined before the installation of the steel structure column.

[0024] Step S2, install the steel ladder and operate the steel platform. Before hoisting, the steel ladder should be installed on the steel column on the ground for the climbing operation. The outside is the operating steel platform set at the joint position with the upper column, which should also be installed on the steel column on the ground.

[0025] In step S3, connecting lugs are fixed on the four sides of ...

Abstract

The invention discloses a lifting method of high-rise steel structure columns. The lifting method of the high-rise steel structure columns includes the steps that the length, the section, side bendingand the elevation of a bracket face of each steel structure column are pre-detected; a steel ladder and an operating steel platform are installed on the steel structure columns; connecting lug platesare fixed on the four side faces of the top end of each steel structure column correspondingly; the steel structure columns are lifted in position; verticality and displacement of the steel structurecolumns are tested; the steel structure columns are welded in a butt jointing mode and are tightened by clamp plates and bolts; the connecting lug plates are cut off; and rigging is demolished. According to the lifting method of the high-rise steel structure columns, the lifting of the high-rise steel structure columns is conveniently, quickly and accurately realized.

Description

technical field [0001] The invention relates to the technical field of steel structure hoisting. Background technique [0002] Many existing buildings use steel structures, especially many workshops. Because of the large demand for space and the requirements of saving construction costs, most of them choose steel structure engineering for construction. Steel structure engineering uses many steel components, among which, steel structure column is an important part, and the accuracy and convenience of its hoisting are directly related to the quality of steel structure engineering. However, the existing steel structure columns (especially high-rise steel structure columns) have problems such as easy shaking, inaccurate positioning, time-consuming and labor-intensive hoisting. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for hoisting high-rise steel structure columns, which can realize the hoisting of high-rise steel structure ...
