Joint structure suitable for CRTS II type plate-type ballastless track crossing girder joint
The invention discloses a joint structure suitable for a CRTS II type plate-type ballastless track crossing girder joint, and belongs to the field of ballastless track structure engineering, and the joint structure comprises a base plate arranged on a bridge in the longitudinal direction. A supporting part is arranged on a base plate above a beam seam, a first notch and a second notch are formed in the end parts of two adjacent beam ends respectively, the supporting part is arranged between the first notch and the second notch, and the bottom of the supporting part is connected with the bottoms of the first notch and the second notch respectively, so that the weak part of the base plate is supported; the original beam seam is divided into two gaps; further, the relationship between the distances d1 and d2 from the two longitudinal sides of the supporting part to the adjacent side surfaces close to the beam end and the width d of the beam seam is limited to meet the following conditions: d1 + d2 is greater than or equal to d, d1 is greater than or equal to 1/3d and less than or equal to 2/3d, and d2 is greater than or equal to 1/3d and less than or equal to 2/3d, so that the sum of the gaps d1 and d2 on the two sides of the supporting part can meet the maximum length that the beam end can extend, namely the width d of the seam, and meanwhile, the base plate can directly span two gaps separated by the beam seam; the structure is simple and durability is high.
本发明公开了一种适用于CRTSⅡ型板式无砟轨道跨越大梁缝的接缝结构，属于无砟轨道结构工程领域，包括沿纵向设置在桥梁上的底座板。其通过在梁缝上方的底座板上设置有支撑部，并在相邻两梁端的端部分别设置第一缺口和第二缺口，将支撑部设置在第一缺口和第二缺口之间，其底部分别与第一缺口、第二缺口的底部相接，实现对底座板薄弱处的支撑，并将原梁缝分隔成两间隙；进一步地通过限制支撑部的纵向两侧距相邻近梁端的侧面的距离d1、d2与梁缝宽度d之间的关系满足：d1+d2≥d，且1/3d≤d1≤2/3d，1/3d≤d2≤2/3d，使支撑部两侧的间隙d1、d2之和能够满足梁端可以伸长的最大长度即缝宽d，同时使底座板可以直接跨越大梁缝分隔后的两间隙，结构简单，耐久性高。
