Embodiment Construction

[0013] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0014] A quick method for welding flat curved T-rib units, the specific method is as follows:

[0015] S1: Blanking of the flange plate: during the blanking process of the curved T-rib top and bottom plate unit, when the T-rib flange plate on the same steel plate is single-piece blanked, a certain amount is reserved between each flange plate. The spacing is not cut off, even if the adjacent flange plates are connected as a whole, they will not be separated;

[0016] S2: Assembling and welding of T-rib webs: Assemble and weld T-rib webs on the steel plate of the integral flange plate of the fan, and perform unified correction after welding;

[0017] S3: Segmentation of T-rib: After the T-rib assembly, welding and correction are completed, it is cut and separated along the i...

Abstract

The invention relates to a fast and convenient group welding method of a plane curved T ribbed slab unit. The fast and convenient group welding method is characterized by comprising the following steps of 1: the overall feeding of wing edges; 2: welding of T ribbed webs and T ribbed wing edges; 3: cutting of T ribs; and 4: welding of T ribs and bottom plates. According to the fast and convenient group welding method, as each T rib is not cut, a whole like a plate unit is formed, and welding deformation is reduced; and by means of the fast and convenient group welding method, the difficulty ofT ribbed slab unit assembly is greatly reduced, the correcting quantity of T ribbed group welding deformation is reduced, and the group welding progress of the curved T ribbed slab unit is accelerated.

Description

technical field [0001] The invention relates to the technical field of welding methods, in particular to a fast method for assembling and welding planar curved T-rib units. Background technique [0002] At present, the top and bottom plates of steel box girders of most ramp bridges are planar curved T-rib unit structures. Since the T-rib flange plates and webs on the same plate unit are all curved, and the lengths and radii of curvature are different, according to The conventional method is to make a single T-rib, and then weld the single T-rib with the steel plate unit, and the speed of welding the T-rib unit is very slow. Therefore, it is necessary to develop a fast method for machining planar curved T-rib units. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fast method for assembling and welding plane curved T-rib units, which can solve the problem that the speed of welding T-rib units for curved T-rib un...
