Abstract
The utility mode discloses a longitudinally-connected track slab with shoulders, which belongs to the technical field of longitudinally-connected track slabs. The longitudinally-connected track slab with shoulders comprises a track slab body. A groove is arranged at the end of the track slab body. 1/38 to 1/42 track cants are arranged at the surfaces of track carrying stages with shoulders of the longitudinally-connected track slab. At least two rows of rectangular reinforcing steel bars are embedded at the longitudinal direction of the end of the track slab body, and the lower ends of the rectangular reinforcing steel bars expose out of the track slab body. Because the utility model enables the longitudinally-connected track slab and a road base to reliably connect, not only the structure is simple, but also the shearing stress of the longitudinally-connected track slab on the road base can be effectively transmitted and dispersed to adjacent track slabs to prevent the ends of the track slabs from breaking off because of the sedimentation of the road base.

Background technology
Existing longitudinal-connecting type track slab is to be connected with roadbed by the bottom under the plate laying on the line, and this connected mode is unreliable.Present longitudinal-connecting type track slab directly connects longitudinal reinforcement by junction plate, though can reaching ballastless track, this connected mode gets on the right track vertical connection between plate and the track plate, but for the inhomogeneous location of subgrade settlement, cause the longitudinal-connecting type track slab part unsettled probably, under alternating stresses the active force to track plate end of train wheel to formation, the end of longitudinal-connecting type track slab is very easily fractureed, " nodding " phenomenon of the track plate end of often saying just, thus cause the damage of track.
The utility model content
The purpose of this utility model is: provide a kind of track plate to be connected with roadbed reliably, and can guarantee longitudinal-connecting type track slab shear stress on the roadbed effective transmission, be distributed on the adjacent track plate, effectively reduce train wheel to the effect to track plate end of the alternating stresses that forms, preventing has a shoulder block longitudinal-connecting type track slab because of what subgrade settlement caused that track plate end fractureed.
The technical solution of the utility model is: a kind of have a shoulder block longitudinal-connecting type track slab, comprises track plate plate body, and track plate plate body end is provided with groove, and the support rail platform table top of described track plate is provided with 1: 38～1: 42 rail cant; Described track plate plate body bottom surface longitudinal direction is embedded with at least two row's rectangle reinforcing bars, and rectangle reinforcing bar lower end is exposed to outside the track plate plate body.Track plate plate body bottom surface longitudinal direction described here is meant: the direction of moving towards unanimity of the rail of installing on the track plate.
Described track plate plate body bottom surface longitudinal direction respectively is embedded with row's rectangle reinforcing bar near the plate body marginal position.
Be embedded with shear device on the described groove, this shear device comprises junction plate, junction plate one side is fixed with embedded bar, the junction plate opposite side is fixed with shear plate, wherein, described embedded bar and junction plate are embedded in the track board concrete in advance, and the one side that described junction plate is connected with shear plate exposes to described bottom portion of groove, and described shear plate exposes to track plate end; Described shear plate one side at least is provided with tooth, and the teeth groove direction of described tooth is vertical with junction plate, also is provided with at least one connecting hole on the described shear plate.
Described embedded bar is the U-shaped reinforcing bar.Make be connected between embedded bar and the track board concrete more firm.
The end of described U-shaped reinforcing bar is outwardly-bent.This structure has further strengthened the fastness that is connected between embedded bar and the track board concrete.
Described embedded bar adopts hot rolled ribbed steel bar.
Described connecting hole is a bar hole.Connecting hole on the shear plate adopts the structure of bar hole, can regulate when being convenient to the shear plate engagement of two track plates.
Described embedded bar is fixed on junction plate one side with welding manner, and described shear plate is fixed on the junction plate opposite side with welding manner.Adopt this mode that is connected to make that connection is more reliable.
The beneficial effects of the utility model are: it is more reliable to make that the track plate is connected with roadbed, the utility model is not only simple in structure, and can guarantee longitudinal-connecting type track slab shear stress on the roadbed effective transmission, be distributed on the adjacent track plate, effectively reduce the effect of normal pressure, prevent to be fractureed because of subgrade settlement causes track plate end to track plate end; When variations in temperature occurring, when longitudinal-connecting type track slab expanded with heat and contract with cold, because of the tooth that engagement is vertically arranged of the shear plate of adjacent longitudinal-connecting type track slab, this tooth can slide along the teeth groove direction, thereby guaranteed the reliability that connects between the track plate.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
