Abstract

The invention discloses a manufacturing method of a large steel formwork. By adoption of the manufacturing method of the large steel formwork, the problem that a large steel formwork cannot be weldedreliably is solved, the problems of large welding quantity and large welding deformation are also effectively solved, and it is ensured that the product manufacturing precision meets design requirements. According to the technical scheme, the manufacturing method of the large steel formwork comprises the following steps that steel plates and profiles are fed and formed according to set dimensions,and grooves are machined in the steel plates; panels and angle iron are positioned through spot-welding and then are welded; after shear nails are welded on the panels, the adjacent panels are assembled through welding to form a panel assembly; a partition plate is welded on one side face of the panel assembly, and then channel steel is welded; another panel assembly is welded to the end of the partition plate, and the two panel assemblies are oppositely assembled through welding to form a sub-module; and the ends of two sub-modules are perpendicularly assembled through welding to form the steel formwork.

Description

technical field [0001] The invention relates to the technical field of steel module welding, in particular to a method for manufacturing a large steel module. Background technique [0002] The existing large steel module is used as a narrow cavity type welded structural part (its structure is as follows Figure 1a-1b , figure 2 As shown), it is mainly composed of upper and lower panels, partitions, angle steel, channel steel, and shear nails. Large-scale steel modules are generally of irregular structure, and there are many parts inside, and the parts are mainly connected by welding, with a large amount of welding and great welding deformation. For the above-mentioned problem of extremely large welding deformation, the prior art mainly adopts a predetermined amount of anti-deformation before welding, and performs appropriate mechanical correction after welding. Although the existing technology has reduced the welding deformation to a certain extent, due to the influence o...
