The U.S., Canada, Brazil, Australia, South Africa etc. by existing line upgrading or newly-built heavy haul railway heavy haul railway with
Largely start heavy haul train, also starts to start heavy haul train on passenger-cargo mixed fortune main line based on passenger traffic in Europe.Chinese big
Qin Tielu largely starts 25t axis weight heavy haul train, and Shuohuang Railway has by enhanced transformation and starts 30t axis weight heavy haul train energy
Power, it is newly-built by watt day of 30t axis heavy load design railway and covering Sinorael road and having and start 30t axis weight heavy haul train ability, separately
Outside, Chinese Railway parent company will develop in both wired backbones and start 27t axis heavy train.
In railway construction, there are many forms as the structure across barriers such as river, highways for bridge, have prestressing force mixed
Solidifying Tu Liang, reinforced beam, girder steel, and steel reinforced concrete bondbeam is used on a small quantity, such as deck type steel case girder bondbeam, Through Steel
The bondbeam span ability of purlin girder bondbeam etc., existing structure form is relatively large, but structure is relatively complicated, structure
It is self-possessed also larger.Medium and small span when for creating heavy haul railway or both wired enhanced transformation, using existing structure form bondbeam
There are certain shortcomings.
The steel reinforced concrete bondbeam of existing heavy haul railway application mainly in new route, and generally steel case girder bondbeam or
Steel truss girder bondbeam, applicable span are generally 32m or more, and structure is complicated, are self-possessed larger；It is less suitable for medium and small span
With.(1) existing steel case girder bondbeam is such as used in medium and small span bridge, and since building height is small, personnel cannot be introduced into steel case
Carry out inspection and maintenance；Base-supporting steel truss girder bondbeam building height is too big, and steel and concrete amount are big, and there are unnecessary
Waste.(2) both wired enhanced transformation when, often restricted to beam body height or upper space at bridge pier, existing pattern knot
It closes beam and is not able to satisfy this requirement.]

The steel-concrete composite beam structure of railway.To solve the disadvantage in above-mentioned background technique.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of steel-concrete composite beam structure suitable for heavy haul railway, steel girder is using duplexing fashioned iron, steel girder and floorings
It is connected as entirety, the steel girder beam body is designed using variable cross-section, and end beam body height is lower than the height of intermediate beam body, is become and is cut
Arc transition is used at face, is provided with horizontal-associate between duplexing fashioned iron and is attached.
Further, the horizontal-associate includes intermediate cross frame or the end horizontal-associate being arranged at support.
Further, by the drum steel upper surface weld stud or WELDING STUDS the steel girder and described
Floorings be connected as entirety.
Further, the steel main beam structure is connected by web, is provided with ribbed stiffener on the outside of web.
Further, the intermediate cross frame passes through high-strength bolt and gusset plate and two drum steel girder web plate ribbed stiffeners
It connects.
Further, ribbed stiffener is equipped at the steel girder arc-shaped transition section, at top beam point, at support, along steel master
The extending direction of girder construction.
Further, the end horizontal-associate and the work steel main beam are contour, and the end horizontal-associate top flange is logical
It crosses ceramic substrate butt weld to connect with steel girder upper limb, ribbed stiffener, end horizontal-associate at end horizontal-associate web and the support
Lower flange is connected with steel girder lower flange by high-strength bolt.
It is easy for construction from heavy and light the utility model has the beneficial effects that: structure is simple, can it is prefabricated after pass through mast-up
Beam or scaoffold change beam, can also at bridge location cast-in-place concrete floorings；Beam body variable cross-section design, at both wired bridge piers
Height limitation has good adaptability, and good appearance；Arc transition is used at variable cross-section, and one group of short stiffener is set, it can
Concentrated stress is effectively reduced；End horizontal-associate and steel girder connection type improve beam-ends fatigue stress performance.
