一种板式无砟轨道混凝土轨道板
摘要：
本实用新型涉及一种板式无砟轨道混凝土轨道板，包括板体，所述板体内设有若干先张纵向预应力钢筋，所述先张纵向预应力钢筋沿板体的长度方向延伸，所述先张纵向预应力钢筋与板体内的混凝土紧密结合，所述先张纵向预应力钢筋与板体锚固。与现有的先张板相比，由于在生产时，将先张纵向预应力钢筋端部与轨道板之间用锚具锚固，解决了板体与先张纵向预应力钢筋之间仅依赖握裹力进行连接时锚固强度不足的问题，通过锚固的方式在板体端部建立起预应力体系，增加了位于板体端部的混凝土的强度，提高了板体的使用寿命。
摘要（英）：

The utility model relates to a concrete track plate of a plate type ballastless track. The concrete track plate comprises a plate body, wherein a plurality of pretensioned longitudinal prestressed reinforcements are arranged in the plate body, extend in the length direction of the plate body, are tightly connected with concrete in the plate body and are anchored with the plate body. Compared with the conventional pretensioned plate, the end parts of the pretensioned longitudinal prestressed reinforcements are anchored with the track plate by an anchorage device at first in the production process, so that the problem of insufficient anchoring strength in connecting the anchorage pretensioned longitudinal prestressed reinforcements with the plate body by bond stress only is solved, a prestressing system is created at the end part of the plate body in an anchoring way, the strength of the concrete at the end part of the plate body is enhanced, and the service life of the plate body is prolonged.
