The invention relates to the technical field of bridge expansion joints, in particular to an expansion joint structure for road and bridge construction, which is used for solving the problems of poor concrete wrapping property, ineffective cohesion, complicated construction procedures and difficulty in adjustment caused by the fact that an expansion joint structure is composed of various materials with different elastic moduli, and comprises a pavement layer and a beam body, a beam end seam is formed in the end of the beam body, a leveling layer is arranged below the pavement layer and arranged above the beam body, and the pavement layer, the leveling layer and the beam body are connected pairwise from top to bottom. Compared with the prior art, the expansion joint structure is constructed in a pouring integrated forming mode, through the simple structure arrangement of the bridge deck seams and the beam end seams which are distributed in a staggered mode, the compatibility of the expansion joint is improved, the overall performance is improved, the impact load of a vehicle is diffused through the common arrangement of the pavement layer and the leveling layer, and the expansion joint structure is more compact. And the unit type assembly structure can be attached to the beam body erection to complete installation, so that the construction procedures are reduced, and the bridge construction efficiency is improved.
本发明涉及桥梁伸缩缝技术领域，用于解决伸缩缝结构由多种弹性模量各异的材料组成造成的混凝土包裹性差、黏结力失效及伸缩缝的施工工序复杂、调节困难的问题，具体是一种道路桥梁施工用伸缩缝结构，包括铺装层和梁体，梁体的端部设置有梁端缝，铺装层的下方设有找平层，找平层设在梁体上方，且铺装层、找平层及梁体自上而下呈两两相接；本发明与现有技术相比较，该伸缩缝结构采用浇筑一体成型的方式施工完成，通过错列分布的桥面缝和梁端缝的简单结构设置，提升伸缩缝的兼容能力并提升整体性能，以铺装层和找平层的共同设置达到对车辆的冲击载荷完成扩散，且单元式的拼装结构可依附于梁体架设完成安装，减少施工工序，提升桥梁施工效率。
