Problems solved by technology
To form a track, it is necessary to lay multiple track slabs along the track line. When the rail vehicle passes by, the wheels roll over the two ends of the track slab successively, causing the track slab to rise one after another, causing frequent vibration of the slab girder and accelerating the damage of the slab girder; at the same time affecting the train comfort

Embodiment Construction
[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0027] like figure 1 , 2 As shown, the longitudinally connected track slab structure disclosed in the present invention includes a plurality of track slab beams 1 . A plurality of rail slab beams 1 are laid longitudinally and at intervals, a plurality of rail slab beams 1 in a long section or the whole line are connected together by longitudinal tie bars 4 between beam slabs, and there are two parallel and spaced bearing rails on the top surface of the rail slab girder 1 Slot 11. Preferably, two adjacent rail-slab beams 1 are connected together by two symmetrically arranged longitudinal tie bars 4 between beams and slabs.
[0028] The rail plate beam 1 is limited by the limit convex block 6 . Both ends of the rail plate beam 1 are provided with constraining...

The invention relates to a longitudinally connected track board structure and a fabrication and installation method thereof, and belongs to the technical field of track and bridge engineering. The longitudinally connected track board structure includes a plurality of longitudinal track board beams arranged at intervals, the multiple track board beams in a long section or a full line are connectedtogether by longitudinal tensile bars among beam plates, and two parallel supporting track grooves at intervals are formed in top faces of the track board beams. Two adjacent track board beams are connected by two symmetrically arranged longitudinal tensile bars among the beam plates, and the track board beams are post-tensioned prestressed concrete board beams. According to the longitudinally connected track board structure and the fabrication and installation method thereof, the multiple track board beams are connected together to form long section or full line of longitudinally connected board beams through the longitudinal tensile bars among the beam plates. When one ends of the track board beams are stressed, the other ends of the track board beams are pulled by the longitudinal tensile bars so as not to lower downwards heads and rise up upwards, and the overall stability of the track can be enhanced.
Description
technical field [0001] The invention relates to the technical field of rail and bridge engineering, in particular to a longitudinally connected rail plate structure and a manufacturing and installation method thereof. Background technique [0002] Railway bridges are structures constructed for railways to cross rivers, lakes, straits, valleys or other obstacles, as well as to realize the intersection of railway lines and railway lines or roads. Railway bridges are divided into railway bridges and highway-railway dual-use bridges according to their uses; according to their structures, they are divided into girder bridges, arch bridges, rigid frame bridges, suspension bridges, cable-stayed bridges and combined system bridges. The most commonly used railway bridges are beam bridges. It is one of the most widely used bridge types and can be subdivided into simply supported girder bridges, continuous girder bridges and cantilever girder bridges. [0003] With the development of...
