The invention provides a bridge expansion joint device and a mounting method thereof. The bridge expansion joint device comprises a first comb plate mounted at the end of a first beam and a second comb plate mounted at the end of a second beam, and is characterized in that mounting notches are reserved in the end of the first beam and the end of the second beam respectively, a leveling layer and a bottom plate assembly fixed to the leveling layer in an adhesive mode are arranged in the mounting notches. The first comb plate and the second comb plate are arranged above the leveling layer and installed on the bottom plate assembly. The bridge expansion joint device has the advantages that the bridge expansion joint device does not need to prefabricate a bracket, a bridge structure manufacturer does not need to reserve a large notch, before the expansion joint is installed, the bottom plate assembly is bonded and fixed to the leveling layer, then the rotating shaft support is installed, and finally the joint crossing plate and the fixing plate are installed and fixed; because the concrete pouring area is relatively small, the maintenance period is short, and the purposes of rapid installation and rapid traffic can be achieved.

一种桥梁伸缩缝装置及其安装方法，包括安装在第一梁端部的第一梳齿板和安装在第二梁端部的第二梳齿板，其特征在于：在第一梁端部和第二梁端部均预留有安装槽口，在安装槽口内设有调平层和粘接固定在调平层上的底板组件，第一梳齿板和第二梳齿板设于调平层的上方并件安装在底板组件上。本发明的优点在于：该桥梁伸缩缝装置无需预制托架，桥梁结构制造厂家无需预留较大槽口，伸缩缝安装前，先将底板组件粘接固定在调平层上，再安装转轴支座，最后进行跨缝板和固定板的安装与固定，因混凝土浇筑的面积较小，因此保养周期较短，可以实现快速安装和快速通车的目标。
