Processing and manufacturing method of huge pentagonal steel column

Abstract

The invention discloses a processing and manufacturing method of a huge pentagonal steel column, and the method is characterized in that the huge pentagonal steel column comprises upper flanges, a lower flange, a web, a middle division board, a gusset and a horizontal division board; the two upper flanges form a herringbone flange; the lower flange and the middle division board form a T-shaped part; the lower flange and the middle division board are fixed vertically; the manufacturing method comprises a part manufacturing step and a complete component assembly step. The processing and manufacturing method of the huge pentagonal steel column has the advantages that all the components are manufactured separately, a manufacturing cycle can be shortened by comprehensive arrangement, and the processing efficiency is improved; no jig needs to be erected, and a lot of materials for ejecting jigs and manpower cost are saved; unified sample ground line size is adopted to control the port sizes of the components, so that the port sizes of all the components are consistent, and the on-site installation precision is improved; the welded components are inspected by repeating the sample ground lines, so that whether the components meet requirements or not can be judged intuitively.

Description

technical field [0001] The invention relates to a processing method for a pentagonal giant steel column. Background technique [0002] With the development of science and technology, steel structures have been widely used in the field of construction instead of traditional brick, stone, and wood structures, especially in super high-rise buildings. 1. The stress of the main structure is complex, and the structural form of the main steel structure tends to be diversified and complicated. For professional manufacturing units of heavy-duty steel structures, it is necessary to continuously explore the manufacturing methods of various complex structures, formulate processing technology suitable for factory production, reduce manufacturing costs and improve production efficiency under the premise of meeting customer requirements. The traditional manufacturing method is to set up a tire frame for horizontal assembly. For a special component such as a pentagon, the tire frame is mor...

AI Technical Summary

Problems solved by technology

The traditional manufacturing method is to set up a tire frame for horizontal assembly. For a special component such as a pentagon, the tire frame is more complicated when it is installed horizontally, and the erection accuracy of the tire frame will directly affect the assembly accuracy of the component. The size can only be controlled by manual measurement, and there are great uncertainties
