Processing method for stiffening plates in reinforcing area of large-diameter tubular column

Abstract

The invention relates to a processing method of stiffening plates in a reinforcing area of a large-diameter tubular column, and belongs to the technical field of processing and manufacturing of building steel structural members. The processing method comprises the following operation steps that firstly, rolling and forming are carried out on the large-diameter tubular column by adopting a plate rolling machine, and welding is carried out on longitudinal seams after rolling and forming; secondly, the surface of a longitudinal weld joint is polished to be flush with a base metal after welding; thirdly, outer ring stiffening plates are welded to the lower end of a variable-cross-section circular pipe, the upper end of a straight-section circular pipe and the position between the variable-cross-section circular pipe and the straight-section circular pipe; fourthly, an end transverse stiffening plate is welded to the middle of the variable-cross-section circular pipe, then transverse stiffening plates and vertical stiffening plates are installed and welded in the variable-cross-section circular pipe and the straight-section circular pipe, welding is conducted through a taking and retreating method, and finally the end transverse stiffening plate is welded to the end face of the straight-section circular pipe; and fifthly, an inner stiffening plate is welded to the end face of the variable-cross-section circular pipe. The processing method has the characteristics of simple structure, high efficiency and long service life. The problem of high processing difficulty of the stiffening plates in the reinforcing area is solved, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing of building steel structure components, in particular to a processing method for a stiffening plate in a large-diameter circular pipe column. Background technique [0002] Due to the small number of vertical steel columns in the long-span space structure, the load transmitted from the floor (roof) to the steel columns is very large and complicated. If the column head joints are designed as steel castings, the cost is too high. Therefore, designers often set reinforcement areas at the beam-column connections. In the reinforced area, the horizontal and vertical stiffeners are dense, the welding space is small, and the welding is difficult. If the method is not proper, the quality of the weld will not pass the standard, and it is easy to cause safety hazards. How to choose a safe and efficient manufacturing method is a difficult problem faced by every steel structure manufacturi...
