Description
Technical field
The present invention relates to field of track traffic, more particularly to combined type overhead monorail traffic track beam and its processing technology.
Background technology
Suspension type monorail traffic system, that is, overhead rail train, track is square ON TRAINS, is supported by steel or cement post
In the air.Due to moving in the air traffic above-ground, city friendship can be alleviated on the basis of without extending city existing highway facility
Logical problem.Again since it only moves to track in the air, rather than entire road surface is lifted as elevated railway or riding single track
Enter aerial, therefore overcome the disadvantage of other Rail Transit Systems, build and operator face have the characteristics that much to protrude with
Advantage.Although there is lot of advantages, existing suspension type monorail traffic track beam manufacture to be primarily present for suspension type monorail traffic
Following difficult point：
(1) existing track girder is using armored concrete precast construction, then its quality is larger, construction transport and in-site installation
Difficulty is larger, and used lifting machine is more demanding, and construction cost is higher, and construction safety risk is larger；It is prefabricated by template
Reinforced concrete structure, apparent size precision is poor, and track girder inner section flatness is difficult to ensure, train is caused to advance
It relatively jolts in the process, comfort level is poor.
(2) existing track beam body be bottom disconnect silent section form, using steel plate welding fabrication, then be pass through by
Steel plate is cut into strips, and by the vertical assembled welding fabrication of board group, welding engineering amount is larger, and manufacture efficiency is low, welding deformation amount
Greatly, track girder formed precision is poor, and quality is difficult to ensure；The shape of transverse stiffener is irregular simultaneously, leads to cutting for stiffener
Cut off material loss greatly, cost wastes serious transverse stiffener and the attachment weld and track beam body attachment weld of main body casing,
Intersection and overlay region are more, easily cause weld seam accumulation, node quality are influenced, if according to welding for steel structure code requirement, to keep away
Track beam body attachment weld is opened, welding hole was set on ribbed stiffener, then can increase the blanking loss of ribbed stiffener, and weld seam does not connect
Continuous, welding efficiency is extremely low.
