Description
Technical field
The utility model belongs to technical field of bridge engineering, and bridge is built in more particularly to a kind of highway, railway or track traffic jointly
Beam bilayer main beam section constructs.
Background technology
With the fast development of our national bridge constructions, increasing long-span highway, railway or track traffic are closed
Bridge construction beam is built, but many complicated landforms are got down the highway, railway or track traffic build adaptation of the bridge to two sides wiring jointly
Property and operation the maintenance stage the problem that influences each other it is outstanding day by day.
At present, the highway of home and overseas, railway or the dual-purpose bridge of track traffic use highway in upper, railway or rail substantially
Rebuilding scheme of the road traffic under, or highway, railway or track traffic flat bed arrangement, girder using steel truss girder or
Flat bed steel box-girder is arranged.It is however, along with the constraint for more repeating miscellaneous wiring condition and dual-purpose to highway, railway or track traffic
Bridge operation, the continuous attention of maintenance, traditional highway in rebuilding scheme under of upper, railway or track traffic and
Flat bed girder also runs into some problems.
The subject matter of double-deck girder pattern of the highway in upper, railway or track traffic under is embodied in：Some landform bars
Part can not be arranged as highway upper, and bilayer of the railway under builds form jointly.If highway above railway, can cause two by force
Bank highway access bridge length is very long, and the maintenance and maintenance of highway bridge have a strong impact on the operation of railway；Truss upper strata bolt breaks
Splitting can have an impact to railway operation；Highway and the division of the working interface of railway maintenance are unintelligible；Driving visual angle is poor；Train
Fire jeopardizes main beam structure safety etc..
The problem of girder of highway, railway or track traffic flat bed arrangement, is embodied in：Some orographic conditions determine if
Be arranged to the girder pattern that rail-road flat bed is built jointly, can also cause highway, the absolute altitude of railway or a track traffic wherein side raise or
Reduce, even if being arranged as the bridge that highway, railway or track traffic flat bed are built jointly, be also required to set anti-throwing between highway and railway
Net, Bridge Landscape is had a strong impact on, and increase the wind load of bridge；If the beam wind of train can cause the cross force of automobile,
Driving safety is influenceed, therefore typically wants the ventilative wind barrier of setting unit；To be set between highway and railway or track traffic anti-
Higher ranked anti-collision wall is hit, otherwise highway errant vehicle easily hits railway.Highway, railway or track traffic flat bed arrangement,
And railway is located at both sides, railway passenger can be caused to can only see highway bridge, can't see river and valley positioned at centre, highway
Beautiful scenery, and train by when, have psychological impact to the driver of road vehicle.
Utility model content
The utility model type technical problem to be solved is to provide a kind of highway, railway or track traffic and builds bridge pair jointly
Layer main beam section construction, significantly to save the connection charge of two sides, influencing each other for railway in operation and highway is greatly reduced, and
It is obviously improved the gap bridge landscape of highway and railway passenger.
Technical scheme is as follows used by the utility model solves its technical problem：
Bridge main beam cross-section structure, including left side highway are built in a kind of highway, railway or track traffic of the present utility model jointly
Girder, right side highway girder, and positioned at railway trusses between the two, it is characterized in that：The railway trusses and left side highway
Girder, right side highway girder use double-layer structural, and railway trusses is located at upper strata, and left side highway girder and right side highway girder are located at
Lower floor, railway trusses underface and left side highway girder, right side highway girder set the 4th road between inner side.
4th road is pavement, is either bicycle lane or is pavement and bicycle lane.
The beneficial effects of the utility model are can to greatly save the connection charge of two sides, while highway and railway or track
Traffic is mutually independent of each other with maintenance, especially highway bridge overhaul and railway or the shadow of meeting of track traffic bridge floor overhaul
Ring, operation and maintenance cost greatly reduce；Automobile and the train travel visual field are relatively open, and pedestrian can also pass through transparent floorings
See river, Bridge Landscape effect is preferable；On the left of highway or right side girder can be initially formed in construction, can also once be formed
Highway girder, the web member and lower boom of railway trusses being set up above Zai highway girders, railway girder may be readily formed as welding trusses entirely,
The difficulty of bridge construction and the maintenance of railway girder are substantially reduced, and because not having bolt, will not also produce high-strength bolt
Delayed fracture, it is ensured that the operation security of pedestrian, non-motor vehicle and highway；It is applied widely, can be used as beam bridge, arch bridge, tiltedly
Draw the girder of bridge and suspension bridge.
