一种装配式无砟轨道结构及其纵向连接结构
摘要：
本发明公开了一种装配式轨枕板式或轨道板式无砟轨道结构的纵向连接结构，及包含该纵向连接结构的无砟轨道结构，预埋的纵向钢筋通过挤压套筒进行纵向连接，两个纵向钢筋的对接端分别插入所述挤压套筒的两端内，在便携式挤压机的挤压下，所述挤压套筒变形锁紧。本发明可提高现场铺设施工时的精度，方便拆卸和安装，降低施工难度，提高现场施工速度，且结构简单，方便轨枕板或轨道板的定位。
摘要（英）：

The invention discloses a longitudinal connecting structure of an assembled sleeper slab-type or a track slab-type ballastless track structure and a ballastless track structure including the longitudinal connecting structure. Two embedded longitudinal steel bars are longitudinally connected through an extrusion sleeve, the butting ends of the two longitudinal steel bars are separately inserted into the two ends of the extrusion sleeve, and the extrusion sleeve deforms and is locked under the extrusion of a portable extruder. According to the longitudinal connecting structure of the assembled sleeper slab-type or the track slab-type ballastless track structure and the ballastless track structure including the longitudinal connecting structure, the accuracy during site laying construction can be improved, disassembly and installation are convenient, the construction difficulty is reduced, the speed of site construction is increased, the structure is simple, and positioning of a sleeper slab or a track slab is convenient.
