Prefabricated and assembled separable concave-convex groove connection type track structure
The invention discloses a prefabricated and assembled separable concave-convex groove connection type track structure. A prefabricated track beam is connected with a prefabricated base beam through a cast-in-place connecting part; the prefabricated track beam comprises a track beam longitudinal beam, a track beam transverse beam, a track beam rail bearing table and a track beam convex column, the lower end of the track beam convex column is coated with an isolating layer, the prefabricated base beam comprises a base beam longitudinal beam, a base beam transverse beam and base beam grooves, and the base beam grooves are formed in the base beam longitudinal beam at intervals; when the base beam groove and the track beam protruding column are installed, the base beam groove and the track beam protruding column are in an up-and-down corresponding state. The track beam convex columns at the lower ends of the prefabricated track beams are inserted into the base beam grooves, then strength connection is conducted in a cast-in-place construction mode, the assembly rate of the track structure is increased, and the workload of cast-in-place is reduced; according to different vibration reduction requirements, the track beam convex columns are wrapped with vibration reduction cushion layers or additionally provided with vibration reduction base plates, the track beam can be applied to sections without vibration reduction or sections with different vibration reduction requirements, the track structure types are reduced, and adjustment of the vibration reduction grade in the operation stage is facilitated.
本发明公开一种预制装配可分离的凹凸槽连接式轨道结构，预制轨道梁通过现浇连接部与所述预制底座梁连接；预制轨道梁包括轨道梁纵梁、轨道梁横梁、轨道梁承轨台、轨道梁凸柱及轨道梁凸柱的下端包覆隔离层，预制底座梁包括底座梁纵梁、底座梁横梁和底座梁凹槽，底座梁凹槽在所述底座梁纵梁上呈间隔布置，底座梁凹槽与所述轨道梁凸柱安装时，呈上下位置对应状态。预制轨道梁下端的轨道梁凸柱插入到底座梁凹槽中，然后通过现浇施工方式进行强度连接，提高轨道结构的装配化率，减少现场浇筑的工作量；根据不同减振需求，轨道梁凸柱外包裹减振垫层或增加减振垫板，可应用于无减振或不同减振需求地段、减少轨道结构类型、方便运营阶段减振等级的调整。
