Manufacturing method of dislocated spliced perforated combined beam

Abstract

The invention relates to a manufacturing method of a dislocated spliced perforated combined beam. The manufacturing method comprises the following steps of 1) calculating to obtain the size of a steel plate before cutting according to the size of a web needing to be perforated and the size of a hole, and performing discharging processing to form a toothed trough plate I and a toothed trough plate II; 2) dislocating the toothed trough plate I and the toothed trough plate II, aligning teeth crests and splicing the teeth crests, and performing full-length welding on a part at each section to form the web; 3) vertically welding an upper flange and a lower flange on the outer sides of the toothed trough plate I and the toothed trough plate II; 4) welding end plates at the end parts of the toothed trough plate I and the toothed trough plate II; 5) welding stiffened plates on two sides of the web; and 6) welding sealing plates in small space segments formed among the end plates, the flanges and the stiffened plates and between the flanges and the stiffened plates, so that a dislocated spliced perforated part is coated with the concrete combined beam. The effects of realizing one-time pouring molding and reducing steel consumption are achieved on the basis of ensuring the performance index of a component.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a building component, in particular to a method for manufacturing a composite beam with dislocation splicing and openings, and belongs to the technical field of construction engineering. 【Background technique】 [0002] At present, my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. In traditional buildings, most of the work needs to be completed on the construction site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction personnel have become barriers to the progress of the construction industry. [0003] The partially clad concrete composite structure (PEC structure) is produced by an industrial production line. The concrete is directly poured into the semi-open cavity surrounded by the steel flange and the steel web. The pouring on the formwork does not require addi...

Problems solved by technology

Although PEC components still have the above-mentioned advantages, they still need to be poured twice during production, which increases the production cost and cycle
