Abstract

The invention discloses a vertically-type rail plate with bumping shoulders, belonging to the technical field of vertically-type rail plates. The vertically-type rail plate with the bumping shoulders comprises a rail plate body the end part of which is provided with grooves; the rail-bearing platform surface of the rail plate is provided with 1:38 to 1:42 rail bottom slopes; at least two rows of rectangular reinforced steel bars are pre-embedded at the bottom surface of the rail plate body in the longitudinal direction; and the lower ends of the rectangular reinforced steel bars expose out of the rail plate body. The invention enhances the connection between the rail plate and a roadbed, not only has simple structure, but also can ensure the shearing stress of the vertically-type rail plate on the roadbed to be effectively transferred and dispersed on the adjacent rail plates and prevent the end of the rail plate from being broken by the sedimentation of the roadbed.

Description

The shoulder block longitudinal-connecting type track slab is arranged
Technical field
The present invention relates to a kind of track plate, especially relate to a kind of longitudinal-connecting type track slab.
Background technology
Existing longitudinal-connecting type track slab is to be connected with roadbed through 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 through junction plate; Get on the right track vertical connection the between plate and the track plate though this connected mode can reach ballastless track,, cause the longitudinal-connecting type track slab part unsettled probably for the inhomogeneous location of subgrade settlement; 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 just often saying, thus cause the damage of track.
Summary of the invention
The objective of the invention is to: 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 tracks adjacent 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.
Technical scheme of the present invention 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 said track plate is provided with 1: 38～1: 42 rail cant; Said 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.Be embedded with shear device on the said groove; This shear device comprises junction plate, and junction plate one side is fixed with embedded bar, and the junction plate opposite side is fixed with shear plate; Wherein, Said embedded bar and junction plate are pre-buried in the track board concrete, and the one side that said junction plate is connected with shear plate exposes to said bottom portion of groove, and said shear plate exposes to track plate end; Said shear plate one side at least is provided with tooth, and the teeth groove direction of said tooth is vertical with junction plate, also is provided with at least one connecting hole on the said shear plate.
Said track plate plate body bottom surface longitudinal direction respectively is embedded with row's rectangle reinforcing bar near the plate body marginal position.
Said embedded bar is a U shaped steel muscle.Make be connected between embedded bar and the track board concrete more firm.
The end of said U shaped steel muscle is outwardly-bent.This structure has further strengthened the fastness that is connected between embedded bar and the track board concrete.
Said embedded bar adopts hot rolled ribbed steel bar.
Said 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.
Said embedded bar is fixed on junction plate one side with welding manner, and said 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 invention has the beneficial effects as follows: it is more reliable to make that the track plate is connected with roadbed; The present invention 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 tracks adjacent 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 appearance temperature changes, 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 accompanying drawing and the specific embodiment the present invention is further specified.
