Embodiment 1

[0042] Such as Figure 1-Figure 3 As shown, an assembled ballastless track unit plate includes a unit plate body 11, several installation chambers 7 preset on the unit plate body 11, and reserved on the unit plate body 11 There are several connecting channels 8 , each of the installation chambers 7 communicates with one of the connecting channels 8 . The installation chamber 7 is a recessed open-air hole reserved on the unit board body 11, the connecting channel 8 is located inside the unit board body 11, and one end opening of the connecting channel 8 is located in the installation chamber 7 , the other end passes through the unit board body 11 , and the opening is located on the side of the unit board body 11 . In order to realize connection with adjacent unit boards, the installation chamber 7 and the corresponding connecting channel 8 are located at least two edges of the unit board body 11 .

[0043] The shape of the unit plate body 11 is rectangular or wedge-shaped, an...

Embodiment 2

[0046] Such as Figure 4-Figure 5 As shown, an assembled ballastless track slab includes several unit plates 1 assembled into a track slab, and a connecting mechanism 2 connecting the unit slabs 1, wherein, along the transverse direction of the track slab, at least two mutually connected The unit plate 1, and also includes at least two interconnected unit plates 1 along the longitudinal direction of the track plate. The shape of the unit plate 1 is rectangular or wedge-shaped, and the unit plate 1 may include various sizes. Such as Figure 11 As shown, all the unit plates 1 form a continuous track plate structure.

[0047] The unit plate 1 is pre-embedded with connecting steel bars 3 for connecting with the substructure. The unit plate 1 is also provided with a rail platform 6, and both the unit panel 1 and the rail platform 6 are preset with fastener installation holes 5, and the fastener system is installed on the rail platform 6, and through the rail platform 6 can real...

Embodiment 3

[0050] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the unit plate 1 is not provided with a rail support platform 6, and the fastener system is directly installed on the unit 1, and the rail bottom slope is realized through the fastener system.

Abstract

The invention discloses an assembly type ballastless track unit plate and a ballastless track slab. The unit plate comprises a unit plate body and multiple installation chambers formed in the unit plate body in advance. The ballastless track slab comprises multiple unit plates and connecting mechanisms connecting the unit plates, at least two connected unit plates are arranged in the transverse direction of the track slab, and at least two connected unit plates are arranged in the longitudinal direction of the track slab. The assembly type ballastless track slab is assembled through the multiple unit plates, the large-size and large-weight ballastless track slab is divided into pieces, due to the fact that the unit plates are small in size and small in weight, the factory prefabrication difficulty is reduced, the assembled track slab is small in deformation, transport and lifting are convenient, in the operation process, if an off-line foundation is large in deformation, a ballastlesstrack can be divided into small unit plate structures, the replacement and maintenance difficulty is greatly reduced, the adjusting capacity and the repairing capacity of the track slab are enhanced,and the track slab has wide popularization prospects.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an assembled ballastless track slab. Background technique [0002] The track system is a key structural system that directly bears the vehicle load and keeps the vehicle running smoothly in rail transit. It plays a role of connecting the upper and lower in the entire wheel-rail system. The track system is generally composed of steel rails, fasteners, sleepers, track beds and lower support layers. . The track system is divided into ballast track and ballastless track according to the form of the ballast track. The ballast track is constructed of ballast, while the ballastless track is constructed of reinforced concrete. Compared with the ballasted track, the ballastless track has obvious advantages such as better integrity, good stability, good track assembly retention, and less maintenance and repair workload. [0003] Ballastless track first emerged in Europe and J...
