Construction method for manufacturing box type column and beam

Abstract

The invention relates to the technical field of construction, and aims to provide a construction method for manufacturing a box type column and beam. The construction method can effectively reduce welding deformation and reduce the later correction cost. According to the technical scheme adopted in the method, the construction method for manufacturing the box type column and beam comprises the steps of A, marking off, B, marking out, C, discharging, D, groove machining, E, body assembling, F, end plate assembling and G, rust removing and painting. According to the construction method, throughthe reasonable welding sequence and welding manner, deformation is effectively reduced, the later correction cost is reduced, and the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a manufacturing method for box-shaped columns and beams. Background technique [0002] With the development of science and technology, the progress of society, the improvement of people's living standards, and the changes in life concepts and lifestyles, steel structures have gradually penetrated into civil buildings, not just in industrial buildings. Especially in the field of super high-rise steel structures, its superiority is particularly visible. Compared with traditional concrete structures, steel structures have small dead weight, high strength, strong bearing capacity, and high structural safety. Steel structure technology has developed rapidly in recent years. Steel structures The manufacturing level has been greatly improved, and in the next few years, the proportion of steel structure will continue to increase. Box-shaped columns and beams are the most important com...

Problems solved by technology

Box-shaped columns and beams are the most important components of steel structures. However, box-shaped columns and beams in the prior art have a large amount of deformation during processing, and a lot of manpower and material resources are spent in the later repair and correction process. Increased production cost and extended construction period

For example: in the process of welding the bottom wing plate and two side wing plates, after one side wing plate is welded, it is necessary to wait for the welded part to cool naturally before welding the other side wing plate, which greatly prolongs the processing cycle ; If welding is performed without waiting for the welding part to cool completely, welding deformation will be caused by unequal welding shrinkage

And in the prior art, the tooling used for making box-shaped beams and columns has complex structure and poor positioning effect, which affects the processing quality of box-shaped beams and columns
