Mounting structure for unit type multidirectional displacement telescopic device of extra-large bridge
The invention relates to an installation structure of a unit type multidirectional displacement telescopic device of an extra-large bridge, and belongs to the technical field of large-span bridges. The telescopic device comprises a joint crossing plate and a fixed comb tooth steel plate, and one end of the joint crossing plate is fixed on the short step side of the beam end through an embedded bolt set and connected with a multidirectional displacement hinge and a rear anti-collision plate; one end of the fixed comb tooth steel plate is fixed on the long step side of the beam end through an embedded bolt set, reinforcing ribs are embedded in a step bottom plate of the beam end for fixing, a water stop structure is arranged at the position of an expansion joint, and rainwater is treated in a centralized mode through a drainage device. The unit type multidirectional displacement telescopic device installation structure and a beam end step bottom plate are combined into a whole through post-pouring concrete, a beam end cushion block, a beam side cushion block and a beam end partition plate are additionally arranged on a beam section at the position of a support, and a transverse anti-seismic check block is arranged at the end of a pier cover beam. Structural defects of a traditional bridge expansion device are overcome, the damping effect is obvious, noise is reduced, the installation and maintenance links of the expansion device are simplified, and therefore cost is reduced.
本发明涉及一种特大桥单元式多向变位伸缩装置安装结构，属于大跨桥技术领域，该伸缩装置包括跨缝板和固定梳齿钢板，跨缝板的一端在梁端短阶梯侧通过预埋螺栓组固定与多向变位铰以及后置防撞板连接，固定梳齿钢板的一端在梁端长阶梯侧通过预埋螺栓组固定，还包括在梁端阶梯底板预埋加强筋固定，在伸缩缝处设置止水结构并通过排水装置集中处理雨水，通过后浇混凝土将该单元式多向变位伸缩装置安装结构与梁端阶梯底板结合为一个整体，在支座处的梁段增设梁端和梁侧垫块以及梁端隔板，在桥墩盖梁梁端设置横向防震挡块。本发明改变了传统桥梁伸缩装置的结构缺陷，不仅减震效果明显、降低噪音，也简化伸缩装置的安装维护环节，从而降低成本。
