Description
Technical field
It the utility model is related to a kind of track traffic facility.More particularly to a kind of track girder technology.
Background technology
With the national economic development and social progress, the trip of big city people is increasingly relied in track traffic, and right
Rail line in connection city and suburb, overhead section is inevitable, and the track girder for being used to carry train is overhead
The most important component of structure.
Trough girder has the following advantages that：
1) building height is low, Bridge Landscape is good：Trough girder is base-supporting structure, and the more general beam type of building height reduces about
1.3m (by 30m exemplified by), Bridge Landscape effect is good, and is arranged beneficial to track profile.
2) excellent noise reduction effect：When rail traffic vehicles travel on beam channel, its wheel track walking system noise is by both sides master
Beam top flange and the barrier of web, reduce influence of the vehicle noise to surrounding environment to a certain extent；And relative box-girder,
Beam channel is without casing resonance noise.
3) functionals：Using web top surface as emergency evacuation, access path, cable is used as by the use of web inner side
Passage.
4) have a safety feature：There is prevention effect to the derailing situation being likely to occur：Twice abutment wall can ensure that train security row
Sail, prevent derailing and overturn accident.
5) comprehensive economy is excellent：Due to saving side shield and escape platform outside conventional beam type, and simplify sound barrier
Set, compound material dosage is few, low engineering cost.
Because trough girder has many advantages, such as above-mentioned, it is used widely in urban rail transit in China.But due to
Standard channel beam is both designed as prestressed reinforced concrete construction at present, and general span is no more than in 30m, it is difficult to adapt to line crossing road
Road, the needs in river, therefore it is excessive that Cast-in-situ Beam need to be set to carry out at node, constrains the mark of line construction to a certain extent
Standardization and mechanization, and it is connected the overall landscape effect that also have impact on bridge between Standard Beam and node bridge.
The content of the invention
The purpose of this utility model is to provide a kind of track traffic steel reinforced concrete combination trough girder, to solve track traffic steel reinforced concrete group
Technical problem that the loss of weight, the span ability that close trough girder are big, comprehensive cost is cheap etc..
In order to realize foregoing invention purpose, technical scheme is as follows used by the utility model：
Support and connector (2), girder steel on track traffic steel reinforced concrete combination trough girder, including concrete top flange (1), girder steel
Web (3), steel beam web plate stiffening construction (4), girder steel bottom plate and stiffening construction (5) and girder steel and track structure connecting structure (6)；
It is characterized in that：Track girder is undertaken by the girder steel bottom plate and stiffening construction (5) of curved caused tension by connector and girder steel
It is connected with track structure connecting structure (6), girder steel and track structure connecting structure (6) are concrete structure, and laying is overall thereon
Railway roadbed plummer is ballast bed；Girder steel bottom plate and stiffening construction (5) both sides be fixed with by connector undertake track girder by
The steel beam web plate (3) of curved shear stress；The upper end of steel beam web plate (3) is fixedly connected with support and connector (2) on girder steel, on girder steel
Concrete top flange (1) and steel beam web plate (3) are connected to become entirety by support and connector (2)；Steel beam web plate stiffening construction (4)
The steel beam web plate stiffening construction (5) for also serving as track girder cable bearer of inner side is arranged as required to vertically put more energy into or/and level
Put more energy into.
Connector is as needed using a kind of type of attachment in WELDING STUDS, PBL shear connectors or welding U-shaped muscle.
Described steel beam web plate (3) is made using general steel plate or setback steel plate.
Bottom plate longitudinal stiffener uses board-like rib or inverted T-shaped rib as needed for described girder steel bottom plate and stiffening construction (5),
Transverse stiffener uses inverted T-shaped rib.
The utility model has the following advantages that：
Track traffic steel reinforced concrete combination trough girder uses section top flange of the concrete material as simply supported beam, can give full play to
Its compressive property；Steel construction is used in tensile zone, while material tensile property is given full play to, has effectively evaded steel construction
Resistance to compression stable problem.Steel reinforced concrete combination groove profile girder span gets over ability and is better than conventional Pre-stress Concrete U-Shaped Beam, can further expand groove
The use range of type beam；Equal across footpath steel reinforced concrete combination trough girder is only conventional Pre-stress Concrete U-Shaped Beam weight simultaneously
60%, and prestressed setting is eliminated, reduce difficulty of construction and construction period.Although steel reinforced concrete combination trough girder is more pre- in itself
Prestressed concrete groove profile deck-molding, but with cast-in-place node bridge integrate essential, its economy still has some superiority, and meets state
Family goes the requirement of production capacity on green and steel.
