Currently, mostly using Frame Pier and letter when new route (railway, highway, urban rail) is intersected with existing line low-angle
The leap of strutbeam combination or large-span structure one are across leap.For structure of the Frame Pier in conjunction with simply supported beam, span ability has
Limit, landscape effect is poor, the disadvantages of period is long, risk is high of setting a roof beam in place on there is also the pier stud work points for closing on both wired constructions more, line.Mesh
Front baffle pier is generally used in combination with small span beam structure, is since Frame Pier can not carry the weight of large-span structure.For
Large-span structure, that there are costs is high, on build the disadvantages of height is big, while being limited by structure maximum span, had centainly to cross-line angle
Limitation.
(3) utility model content：
The purpose of this utility model is to provide a kind of steel truss girder-Frame Pier bridge structures, it is able to solve the prior art
There are the problem of, intersect work point in route low-angle, using And of Varying Depth steel truss girder, span ability can be effectively increased, reduce frame
Pier quantity, reducing influences existing line, while building that height is small, easy for construction, landscape is good, small investment on having many advantages, such as.
The technical solution of the utility model is：A kind of steel truss girder-Frame Pier bridge structure, it is characterised in that it includes continuous
Girder, bridge pier and the support that steel truss girder is constituted；It is connected between the steel truss girder and bridge pier by support；In the bridge pier at least
One uses Frame Pier；The Frame Pier is located above existing line and crosses over existing line.
The steel truss girder includes top boom, web member, lower boom；The top boom is for curve or to roll over for curved formula, purlin
Coca according to structure stress and landscape it needs to be determined that.
The existing line is existing traffic route or existing pipeline, and the traffic route includes highway, railway, city rail
Road traffic route, the existing pipeline include transmission of electricity pipeline, waterline, petroleum pipeline, gas transmission line or optical cable.
The girder is continuous structure, is made of more than two girder spans.
The span of the girder span is 30~300m.
The steel truss girder using have vertical bar trigonometric expression, without vertical bar trigonometric expression, various purlin formulas such as fraction, Hua Lunshi again.
The steel truss girder is laterally being two panels or multiple-piece construction.
Superhigh intensity construction material can be used in the steel truss girder, composite material is built, and improves span ability, mitigates weight,
Improve lower frame pier stress.
The Frame Pier is made of crossbeam, at least two pier studs, and crossbeam and pier stud use steel construction or concrete structure；
The pier stud and crossbeam use hingedly first, after the completion of steel truss erection, hingedly are changed to be fixedly connected between pier stud and crossbeam,
To reduce stress moment of flexure.
The steel truss girder is built using the construction method of pushing tow, swivel or cantilever.
The utility model has the advantages and positive effects of：
1, the And of Varying Depth continuous steel girder-Frame Pier structural system of the utility model, can be applicable to new route with it is existing
Route low-angle intersects work point, has overall structure permeability good, landscape effect is good；Close on the pier stud work point of both wired constructions
Few, work progress is smaller on both wired influences；Speed of application is fast, and both Wired Securities are effectively ensured；Built in structural system height it is low,
The advantages that span ability is strong, can effectively reduce track profile, good economy performance.2, the utility model can overcome current low-angle across
More both the shortcomings that wired solution.Structurally reasonable, the modern design, good economy performance of the utility model, it is practical, have broader
Application prospect.3, the utility model reduces Frame Pier consolidation moment of flexure by improving Frame Pier structure stress, while by adopting
Mitigate steel truss girder weight with high strength composite etc., realizes structure type of the Frame Pier in conjunction with longspan steel truss girder.
