Description
Technical field
The present invention relates to technical field of rail traffic, more particularly to a kind of suspension type monorail pier stud installation method.
Background technology
Suspension type monorail traffic is a kind of track traffic New Schemes.Decentralization opening thin C-shaped track girder is supported in pier stud, arranges
Car is hung on below track girder by c-shaped opening.Suspension type monorail vehicle uses rubber wheel, and bearing wheed is supported under track girder
On square cantilever bottom plate, travelling wheel and directive wheel are respectively acting on the coxostermum of track girder two.Tradition has been broken away from suspension type monorail traffic
Ground rail travel pattern turn to aerial development, radius of turn is small, climbing capacity is strong, efficiently utilizes city space, delays
Urban traffic blocking is solved, is the important directions of future track transport development.
Suspension type monorail pier stud is the main supporting member of supporting track beam and vehicle, and single line uses L-type structure, and two-wire is adopted
With the structural form of y-type structure, generally steel construction, prefabrication, on-site consolidation.The prefabricated installation accuracy of suspension type monorail pier stud
Control requires strict, and at present, installation method mainly has two kinds：One, steel construction pier stud is blocked and is divided into two parts up and down, is first installed
Bottom pier stud, by setting WELDING STUDS in bottom pier stud side wall, after pour the mode of pile foundation top surface concrete and realize steel construction pier
The combination of post and concrete pile foundation, finally by the mode of welding/bolt/ring flange by top pier stud and bottom pier stud pair
Connect, the positioning adjustment of pier stud can only be realized by the connecting structure between upper and lower pier stud；Two, whole pier stud is as overall complete in factory
Into prefabricated, after pre-embedded anchoring bolts lower concrete pile foundation also one-time-concreting in place, steel superstructure pier stud and concrete-pile
Basis is connected on the ground by foundation bolt/connecting bottom board, and the positioning adjustment of pier stud equally relies on bottom connecting structure.
Due to concrete shrinkage and creep, welding for steel structure error, steel construction pier stud-rear pouring concrete pile foundation adapter section positioning
The influence of the factors such as difficulty causes pier stud installation accuracy to be difficult to ensure that adjustment difficulty is big, causes the erection of track girder is linear to be difficult to
Ensure.
