Prefabricated frame type track beam with connecting convex columns
The prefabricated frame type track beam comprises a track beam longitudinal beam, a track beam transverse beam, a track beam rail bearing table and the track beam convex column, the track beam rail bearing table is installed on the upper surface of the track beam longitudinal beam, and the track beam convex column is installed on the lower surface of the track beam longitudinal beam. Connecting steel bars can be pre-embedded below the track beam convex columns, and the track beam convex columns can also be wrapped by isolating layers. According to the technical scheme, the track beam longitudinal beam, the track beam transverse beam and the track beam rail bearing table form a prefabricated frame type structure, the manufacturing cost is reduced, the track beam longitudinal beam is of a prestressed structure, the structural section size can be effectively reduced, the track beam is prevented from cracking, and the influence of temperature change on beam deflection is reduced; the limiting stability of the track beam is guaranteed, the track beam can be applied to sections without vibration reduction or sections with different vibration reduction requirements by arranging isolation layers made of different materials or adding vibration reduction base plates below the protruding columns, the track structure types are reduced, and adjustment of the vibration reduction grade in the operation stage is facilitated.
本发明公开一种带连接凸柱的预制框架式轨道梁，包括轨道梁纵梁、轨道梁横梁、轨道梁承轨台和轨道梁凸柱，所述轨道梁承轨台安装在所述轨道梁纵梁的上表面，所述轨道梁凸柱安装在所述轨道梁纵梁的下表面，所述轨道梁凸柱的下方可预埋连接钢筋，也可包裹隔离层。本技术方案中所述轨道梁纵梁、轨道梁横梁、轨道梁承轨台组成预制框架式结构，降低制作成本，且所述轨道梁纵梁为预应力结构，可有效减小结构截面尺寸，防止轨道梁开裂、降低温度变化对梁挠曲的影响，凸柱现浇入梁下底座，保证了轨道梁的限位稳定，凸柱下通过设置不同材料的隔离层或增加减振垫板可应用于无减振地段或不同减振需求的地段，减少了轨道结构类型，方便运营阶段减振等级的调整。
