Abstract

The invention discloses a device and method for controlling welding deformation of an unclosed box beam. The device comprises an inner partition plate supporting body which is of a rectangular-plate-shaped structure. A manhole is formed in the center position of the rectangular-plate-shaped structure. Two bolt and nut assemblies I are arranged on the side of one vertical plate of the rectangular-plate-shaped structure and are used for supporting a web of the unclosed box beam, wherein the two bolt and nut assemblies I are located on different sides of the vertical plate. Two bolt and nut assemblies Ii are also arranged on a horizontal plate on the top of the rectangular-plate-shaped structure, and the two bolt and nut assemblies Ii are located on different sides of the horizontal plate and are used for supporting a top plate of the unclosed box beam.

Description

Technical field [0001] The invention relates to a device and method for controlling welding deformation, in particular to a device suitable for controlling C-shaped box beams and a method of use thereof. Background technique [0002] Suspended air rail is a new type of public rail transit. It suspends passenger cars to run on a rail beam in the air. The design speed can reach 60km / kh and the actual running speed is 40-50km / h. The track beam is an unclosed box beam, such as figure 1 As shown, it includes a bottom plate unit 1, a web unit 5, a top plate 9, and a top plate reinforcing rib 8. The connection method of each component is welding. When the inner cavity of the suspended empty rail needs to be welded on the running surface, each part of the plate is subjected to uneven high temperature heating and cooling, which will cause welding deformation. For this unclosed box beam, there is no support in the middle, if it is directly welded , The amount of deformation will be very l...
