Description
Technical field
The utility model relates to steel structure bridge manufacturing field, and specifically a kind of Steel plate bridge beam flange plate and web welding are anti-
Distressed structure.
Background technology
After the completion of large-scale welded H section steel flange plate is welded with web, using traditional-handwork technique, i.e. flame heating and the wing
Listrium straightening machine is corrected.Since flame heating will cause flange plate deflection deformation and longitudinal wave transformation, flange plate to be rectified
Welding bead is easily cracked nearby when positive machine corrects deflection too big component.This two methods is to flange plate postwelding flatness quality
It is required that for high component, correcting and effect unobvious, it is very low that postwelding corrects heavy workload, construction efficiency.
Utility model content
The utility model aim is to provide a kind of Steel plate bridge beam flange plate and web welding anti-distortion technology, according to a large amount of examinations
Part welding machine deformation tendency is tested, reversible deformation assembling effectively reduces postwelding correction workload, improves production efficiency.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of Steel plate bridge beam flange plate and web welding anti-distortion structure, web and flange plate vertical connection, web end
For wedge structure, wedge angle is 55 °；The bevel angle of junction is 35 °；Welding bead with 6 welding in groove, the first weldering
Road is set to vertex, and the first welding bead outside weld is connected to the second welding bead, and the second welding bead outside weld is connected to third welding bead, third welding bead outside weld
It is connected to the 4th welding bead and the 5th welding bead, the 4th welding bead and the 5th welding bead outside weld are connected to the 6th welding bead；The 7th weldering is additionally provided with outside groove
Road.
The advantages of the utility model, feature was：
1, the utility model assembles flange plate and web by certain angle, is welded by divided edge structure, weldering
7 welding structures, postwelding are used to reduce correction workload in termination process.H profile steel flange plate and verticality, flange plate flatness matter
Amount significantly improves.
Description of the drawings
Fig. 1 is schematic diagram before the assembling of utility model.
Fig. 2 is the welding bead structural schematic diagram of utility model.
Fig. 3 is schematic diagram after the completion of the welding of utility model.
Specific implementation mode
With reference to say attached drawing and reference numeral to the utility model be further described.
As shown in Figs. 1-3, a kind of Steel plate bridge beam flange plate and web welding anti-distortion structure, web 8 hang down with flange plate 9
Direct-connected to connect, 8 end of web is wedge structure, and wedge angle is 55 °；10 angle of groove of junction is 35 °；Have in groove 10
The welding bead of 6 welding, the first welding bead 1 are set to vertex, and 1 outside weld of the first welding bead is connected to the second welding bead 2,2 outside weld of the second welding bead
It is connected to third welding bead 3,3 outside weld of third welding bead is connected to the 4th welding bead 4 and the 5th welding bead 5, the 4th welding bead 4 and 5 outside weld of the 5th welding bead
It is connected to the 6th welding bead 6；Ensure the web verticality vertical with flange plate, avoids deforming；The 7th weldering is additionally provided with outside groove 10
Road 7.
First welding bead, the second welding bead, third welding bead, the 4th welding bead and the 5th welding bead use gas shielded arc welding.
6th welding bead, the 7th welding bead use Lincoln weld.
Edge of a wing plate thickness is 30mm.
Web thickness is 20mm.
