Ballastless track, slab, track slab part and track bearing part
The invention provides a ballastless track as well as an assembly, a plate and a track bearing part thereof, which can reduce the use amount of reinforced concrete and improve the structural performance at the same time. The ballastless track comprises a base part; the track plate part comprises a self-compacting layer, a track plate main body with a plurality of hollow grooves corresponding to the plurality of top convex plates, and a plurality of upper cover plates; the rail bearing part comprises two rail bearing table units which extend in the running direction of the train and are located above the peripheral areas of the left side and the right side of the cavity of the rail plate correspondingly, and each rail bearing table unit comprises a plurality of S-shaped rail bearing tables which are sequentially connected end to end to form a wavy continuous extending structure; the S-shaped rail bearing table comprises two blocking shoulders which are parallel to the running direction of a train and are arranged on the two sides of a steel rail in a staggered mode, and an inner connecting plate used for bearing the steel rail and connecting the tail end of one blocking shoulder with the front end of the other blocking shoulder to form a rail bearing groove. The outer connecting plate is used for bearing a steel rail and connecting the tail end of the other retaining shoulder with the adjacent S-shaped rail bearing table to form a rail bearing groove; and a rail section.
本发明提供了无砟轨道及其组件、板与承轨部，能够减少钢筋混凝土的用量，同时提高结构性能。无砟轨道包括：底座部；轨道板部，包括：自密实层，具有与多个顶部凸板相对应的多个镂空槽的轨道板主体，多个上盖板；承轨部，包括沿着列车行驶方向延伸、且分别位于轨道板空腔左右两侧外围区域上方的两个承轨台单元，每个承轨台单元均包括多个首尾依次相连形成波浪形连续延伸结构的S形承轨台；S形承轨台包括：与列车行驶方向相平行、且交错布设于钢轨两侧的两个挡肩，用于承载钢轨、并将一个挡肩的末端与另一个挡肩的前端相连形成承轨槽的内连接板，和用于承载钢轨、并将另一个挡肩的末端与相邻S形承轨台相连形成承轨槽的外连接板；以及钢轨部。
