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 is overhead rail train, and track is square ON TRAINS, is supported by steel or cement post
In the air.Due to traffic above-ground being moved in the air, city friendship can be alleviated on the basis of it need not extend city existing highway facility
Logical problem.Again because it only moves in the air track, whole road surface is lifted rather than as elevated railway or riding single track
Enter aerial, therefore overcome the disadvantage of other Rail Transit Systems, the characteristics of construction and operator face have many prominent and
Advantage.Although suspension type monorail traffic has lot of advantages, existing suspension type monorail traffic track beam manufacture is primarily present
Following difficult point：
(1) using armored concrete precast construction, then its quality is larger for existing track girder, and construction is transported and in-site installation
Difficulty is larger, and the lifting machine requirement for being used is higher, and construction cost is higher, and construction safety risk is larger；It is prefabricated by template
Reinforced concrete structure, its apparent size precision is poor, and track girder inner section flatness is difficult to ensure, causes train advancing
During relatively jolt, comfort level is poor.
(2) existing track girder main body is the section form of remaining silent that bottom disconnects, and is then by inciting somebody to action using steel plate welding fabrication
Steel plate cuts into strips, and by the vertical assembly welding fabrication of batten group, its 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 that；The shape of transverse stiffener is irregular simultaneously, causes cutting for stiffener
Cut off material loss greatly, cost wastes the attachment weld and track girder main body attachment weld of serious transverse stiffener and main body casing,
Intersecting and overlay region is more, easily causes weld seam to be piled up, and influences node quality, if according to welding for steel structure code requirement, to keep away
Track girder main 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.
