Left and right floor is positioned at the outside of left and right web, is welded and fixed between adjacent left and right web by internal partition.The end of upper cover plate is concordant with the outside of left and right floor, and lower cover stretches out the outside of left and right floor.The light material of high strength is filled with in the casing of adjacent two sections of girder junctions.
One end of bracket is fixed on the floor of girder, and the other end is fixed on sleeper beam.Bracket is the junction plate of inclination 45 degree, and two end is respectively equipped with mutually perpendicular fixed head, and two fixed head level and vertically settings respectively, all have bolt hole above.
Buckle lays respectively at the left and right sides of track, buckle comprises base and buckle body, base is bolted on sleeper beam, base has chute, buckle body is positioned at chute and can horizontally slips, the outer end of buckle body is against the bolt having a degree of tightness buckle body, and the inner of buckle body has arc groove down, and the bottom of track is stuck in arc groove.In present embodiment, the material of buckle is plastics.Arc securing member is S shape, is resisted against the top of buckle by bolt.
Girder of the present utility model adopts the entity girder structure by steel plate combination, the box section closed is formed by upper and lower cover plate and two pieces of vertical web, the sleeper beam of bearing track is fixed on girder lower cover or is linked mutually by the floor of bracket with girder, and the intensity of structure and rigidity ensure by box girder.
Sleeper beam also adopts the entity girder structure of steel plate combination, forms drum cross section by upper and lower cover plate and one block of web, and subsidiary fastener fixing device, makes track be fixed on sleeper beam and do not produce movement.
Rail fastening adopts arc securing member buckle and sleeper beam to be fixed, and buckle adopts PAT highstrenghtpiston to make, and avoids track circuit to join electricity.
Horizontal beam of lifting adopts two web special steel beam, coordinates jointly to complete to indulge choose the horizontal operation of lifting and stealing the beams and changing the pillars with girder.
The utility model technical characteristics is:
A. main beam is connected to form the overall structure of long span by junction plate equal strength, meets LONG-SPAN RAILWAY fixed track usage plan and reinforces;
B. beam body adopts two web design, adds the lateral stiffness of structure, makes structure have good lateral stability ability;
C. according to the mechanical characteristic of flexural member, main beam section adopts up-narrow and down-wide type to design, and have employed low clearance design simultaneously, strengthens its stability, improve safety, achieve girder and have higher bearing capacity and the larger scope of application;
D. the connection of girder and sleeper beam adopts inside suspension formula and bottom hang type, according to different line condition, the standard sleeper beam of L=496cm and L=396cm two kinds of length can be used, also can do sleeper beam with the shaped steel of larger supporting capacity at the complex section such as track switch, station, achieve its versatility;
