Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, a track slab includes a track slab body 1, the slab body 1 is a concrete prefabricated part, a rail support platform 2 arranged on the slab body 1, and an insulating pre-embedded casing 3 embedded in the rail support platform 2 , several grouting holes 4 arranged on the central axis of the plate body 1, a plurality of transverse prestressed reinforcement bars 5 and a plurality of longitudinal prestressed reinforcement bars 6 fixed inside the plate body 1; A plurality of oblique prestressed reinforcement bars 7 parallel to each other, the two ends of the oblique prestressed reinforcement bars 7 are respectively connected to the ends of two adjacent transverse prestressed reinforcement bars 5 located on the two opposite sides of the plate body 1, and the oblique prestressed reinforcement bars Stress bars 7 are arranged at intervals between adjacent transverse prestress bars 5, that is, oblique prestress bars 7 are arranged between t...

Embodiment 2

[0028] Different from Example 1, as image 3 , Figure 4 , Figure 5 As shown, the transverse prestressed reinforcement 5, the longitudinal prestressed reinforcement 6 and the oblique prestressed reinforcement 7 are arranged in two layers. staggered arrangement, that is, there is no oblique prestressed reinforcement 7 between adjacent transverse prestressed reinforcements 5 on the upper layer, and the corresponding position of the lower layer is provided with an oblique direction opposite to that of the oblique prestressed reinforcement 7 on the upper layer. To the prestressed reinforcement 7.

Abstract

The invention provides a rail plate which comprises a plate body of the rail plate, multiple transverse prestressed reinforcing steel bars fixedly arranged in the plate body and multiple longitudinal prestressed reinforcing steel bars fixedly arranged in the plate body. The rail plate further comprises multiple parallel oblique prestressed reinforcing steel bars arranged in the plate body. The two ends of each oblique prestressed reinforcing steel bar are connected with the ends, located on the two opposite side faces of the plate body, of the two adjacent transverse prestressed reinforcing steel bars. The oblique prestressed reinforcing steel bars are arranged between the adjacent transverse prestressed reinforcing steel bars at intervals. The surfaces of the transverse prestressed reinforcing steel bars, the surfaces of the longitudinal prestressed reinforcing steel bars and the surfaces of the oblique prestressed reinforcing steel bars are coated with insulating layers. The rail plate has the beneficial effects of being resistant to bending and resistant to pulling.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and in particular relates to a rail slab. Background technique [0002] At present, the ballastless track slab of my country's high-speed railway generally adopts ordinary reinforced concrete structure, and its structure is solid. The concrete material has the characteristics of high compressive strength and low tensile strength, which makes the track slab prone to cracking when it is subjected to lateral force. Although the existing prestressed reinforced concrete track adopts longitudinal and transverse prestressed steel bars to improve certain Bending and tensile strength, but the horizontal bending and tensile strength is still relatively weak, especially when the track slab is applied in a curved section, the track slab is more prone to cracking. Contents of the invention [0003] In view of this, the present invention aims to propose a track slab to solve the problem of poor ...
