Straddle-type monorail curve track girder construction.
Background technology
Load-carrying members and out of shape track of the straddle type monorail rail tracks as train, not only meet specification on structure stress
It is required that and to meet train driving requirement on linear.For the curved section track girder of straddle-type monorail, in the prior art across
Type monorail curve track beam is there are mainly two types of form is arranged, respectively as shown in Figure 1 and Figure 2：
The first is that have straddle-type monorail curve track beam typical case's cross-sectional configuration as shown in Figure 1, this set side
Formula uses at home, and by taking 2, No. 3 line straddle-type monorail lines of Chongqing Light Rail as an example, straddle-type monorail curve track beam is
Using small bore single line box beam, two trajectory beams are independently arranged, and being not provided with lateral ties between two panels track girder (does not adopt
With lateral connection component)；By being found to the existing analysis of project example of this straddle-type monorail, using the first set-up mode
When, it is contemplated that lateral ties, the independent stress of track girder, using mode tensile supporting seat and pier cap beam are not provided between two panels track girder
Connection；The structure lateral stiffness is weaker, and road-ability is poor；Also, since track girder need to rotate the lateral superelevation of realization, bearing
It needs to be in tilted layout, the stress of bearing is unreasonable.
Second is to have straddle-type monorail curve track beam typical case's cross-sectional configuration as shown in Figure 2, this set side
There is presently no uses for the formula country, are mainly used in foreign countries；Such as Las Vegas, US, St. Paul,Brazil ground straddle-type list
Rail track girder uses steel construction lateral connection component, and setting I-steel carries out lateral connection, I-steel between two panels track girder
It is connect using pre-embedded bolt with track girder, steel construction is connect with track girder using articulated manner；By to this straddle-type monorail
Existing analysis of project example is found, when using second of set-up mode, due to being that setting I-steel carries out between two panels track girder
Lateral connection, I-steel are connect with track girder using pre-embedded bolt, and lateral connection component and track girder are hinged, to track girder
Lateral overall stiffness is almost without contribution, supporting member of the steel construction only as fire escape and cable；Also, due to track
Beam need to rotate the lateral superelevation of realization, setting wedge-shaped steel plate be needed between I-steel and track girder, for different superelevation, wedge-shaped steel plate
Size is also different, and processing is cumbersome；In addition, steel construction late maintaining cost is also high.
Straddle type monorail rail tracks lateral dimension is small, lateral stiffness is weak, therefore, how to increase the laterally whole rigid of track girder
Degree improves train driving comfort and straddle-type monorail further genralrlization application problem to be solved.
Utility model content
For the disadvantages described above or Improvement requirement of the prior art, the purpose of this utility model is to provide one kind to have laterally

By the contemplated above technical scheme of the utility model, compared with prior art, due to lateral using concrete
At least two adjacent straddle type monorail rail tracks for moving towards curved section of shape of connecting elements lateral connection so that more after connection
Track girder has better globality, and its lateral stiffness is big compared with steel construction due to concrete lateral connection component so that
The straddle-type monorail curve track girder construction with lateral connection component is driven a vehicle in application with better in the utility model
Comfort.Since setting lateral connection component is the trend of future development, and the utility model is then laterally connected by accordingly improving
The shape and structure of connection member, overcome existing engineering there are the problem of.Track girder lateral dimension is limited general by vehicle
All smaller, the lateral stiffness of track girder is weaker, and the utility model multi-disc track girder is connected as using lateral connection component it is whole
Body, increases the lateral overall stiffness of track girder, while promoting train driving comfort, has to the characteristics of cross-saddle single-track traffic
There are very strong specific aim and adaptability.
Curve track beam beam bottom (i.e. track girder lower surface) in the utility model, which preferably uses, is parallel to setting for horizontal plane
Set mode, can the track beam prefabricated stage realize lateral superelevation (just consider transverse direction superelevation factor in the track beam prefabricated stage,
The upper and lower surface of track girder is designed according to practical application request and is prefabricated into special angle), track girder paving can be substantially reduced
If the difficulty of lateral superelevation adjustment in the process so that bearing can be arranged with horizontal, to also can further improve bearing by
Power, and convenient for the connection of lateral connection component and track girder, and be conducive to improve landscape.
The utility model forms lateral connection component using concrete structure, and since concrete easily conserves, the later stage is substantially not
With maintenance, compared with the prior art employed in other connection structures (such as steel structure connecting member), late maintaining cost will
It substantially reduces.Further, since concrete structure cost is relatively low, construction technology is ripe simple so that will when the utility model is applied
With good economic and practical.
