摘　　要：对当前国内市场主流的桥梁伸缩装置进行了介绍,并通过调查,对梳齿板桥梁伸缩缝的常见病害进行了总结和原因分析,从其病害机理出发,提出一种多向变位复合板式桥梁伸缩装置,不仅适应了部分桥梁预留浅槽口,而且实现了缝体的均匀伸缩和多向变位功能,提高了板式伸缩缝的产品性能和使用寿命。This paper introduced the current mainstream bridge expansion devices in the domestic market,summarized common diseases of the comb plate bridge expansion joint by the investigation,and analyzed their causes.From the disease mechanism,a multi-directional displacement composite plate bridge expansion device was proposed.It not only adapts shallow notches reserved for the bridge but also realizes the functions of even expansion and multi-directional displacement of joints,improving the properties and service life of the plate expansion joint.
