Manufacturing method for box type pillar beam

Abstract

The invention relates to a manufacturing method for a pillar beam for the building field and especially relates to the manufacturing method for a box type pillar beam. The manufacturing method comprises the processes of steel check, line marking, cutting, material receiving, assembling, welding, finishing, coating, and marking. The manufacturing method comprises the following steps: splicing big plates and cutting the box type pillar beam under numerical control; adding lining strips and leaving gaps during the grouping process of four main welding seams of the box type pillar beam; welding the four main welding seams by adopting an automatic submerged arc welding method; welding box type separating plates by adopting non-melting nozzle electro-slag welding; keeping the welding seams of the non-melting nozzle electro-slag welding under an abreast state; machining after grouping the separating plates of the box type pillar beam; and end-milling the two ends of the box type pillar beam. According to the manufacturing method, during a manufacturing process of the box type pillar beam, an advanced box type separating plate non-melting nozzle electro-slag welding technology is adopted; the welding and the assembling are alternately performed; the welding sequence is scientific and reasonable; multiple measures are simultaneously taken for preventing welding deformation; the precise equipment is adopted for processing the end part, so that the manufacturing technology for the box type pillar beam is more advanced and reasonable; and the manufacturing method is suitable for the box type pillar beams in various cross section sizes and plate thicknesses.

Description

technical field [0001] The invention relates to a manufacturing method of a column beam used in the construction field, in particular to a manufacturing method of a box-shaped column beam. Background technique [0002] In recent years, with the development of my country's economic construction, high-rise steel structure buildings have been widely used, among which box-shaped column beams occupy a large proportion in high-rise steel structures, and the current box-shaped specifications and sizes of rolled steel can not meet the requirements Therefore, welded box column beams are widely used in various high-rise steel structure buildings. The manufacturing process of box-shaped components is more complicated than that of other component forms, and the quality requirements are high. In particular, the welding of box-shaped partitions often affects the welding quality and progress due to the constraints of welding positions in the production. Therefore, the development of box-sha...
