Problems solved by technology

Under the long-term load of high-speed and heavy-duty trains, the ballasted track has reached the limit of its carrying capacity, which is reflected in the increasing damage to the gravel track bed, the deterioration of track smoothness, the increase of maintenance work, and the available maintenance time is getting shorter and shorter. The less, it seriously hinders the development of railways in the direction of high speed and heavy load

Embodiment 1

[0022] Such as figure 1 , figure 2 , image 3 As shown, a bearing platform track slab is mainly formed by pouring concrete and built-in steel bars. The middle part of the longitudinal two ends of the track slab is provided with a semicircular notch 4, which is used to cooperate with the convex block on the base to overcome The reaction force caused by the disturbance of the loaded plate under the action of the wheel load; the bearing part of the track plate is symmetrically distributed with caps 3, which increases the distance between the rail and the internal steel bars of the track plate, which is more conducive to the relationship between the rail and the track plate The insulating bolt sleeves 1 embedded in the bearing platform 3 are symmetrically distributed in order to be insulated from the bolts on which the rail is installed; the built-in steel bar nodes of the track slab are insulating nodes, that is, the steel bar nodes inside the track slab are insulated The stee...

Embodiment 2

[0025] Such as Figure 4 , Figure 5 , Figure 6 As shown, a platform-type track slab is mainly formed by pouring concrete and built-in steel bars. There are holes 5 in the height direction of the middle of the track slab, which can save raw materials and reduce the manufacturing cost of the track slab; the middle of the longitudinal two ends of the track slab A semicircular notch 4 is provided, and caps 3 are symmetrically distributed on the rail bearing part of the track slab, and pre-buried insulating bolt sleeves 1 are symmetrically distributed in the caps 3, and the built-in reinforcement nodes of the track slab are insulating nodes, that is, the track The steel bar nodes inside the slab are insulated. The steel bars inside the track slab are cross-bound by vertical and horizontal steel bars. The horizontal steel bars are ordinary steel bars, generally hot-rolled ribbed steel bars. According to the regulations of Rib Reinforcement, the longitudinal reinforcement is made...

Abstract

The invention discloses a support rail plate, belonging to the construction element technique, which is mainly formed by concert and internal steel bar. Wherein, the middle part of longitudinal two ends of rail plate has a semi-circle cut; the support rail has symmetry supports which have symmetry distributed embedded insulated bolt sheathes; and the internal steel bar nodes of rail plate are insulated nodes. The invention has better insulated property, reduced cost, and easy production.

Description

technical field [0001] The invention relates to a railway construction component, in particular to a track slab. Background technique [0002] At present, my country's railways generally use ballasted tracks. Under the long-term load of high-speed and heavy-duty trains, the ballasted track has reached the limit of its carrying capacity, which is reflected in the increasing damage to the gravel track bed, the deterioration of track smoothness, the increase of maintenance work, and the available maintenance time is getting shorter and shorter. The less it is, it seriously hinders the development of railways in the direction of high speed and heavy load. Therefore, there has been the development of ballastless track, which is popular for its maintenance-free or less maintenance, good track smoothness, and good rigidity. However, since the Chinese track circuit transmission system transmits electrical signals through the track, this requires The track slab laid under the rail ...
