Overlapped semi-rigid pile plate node connecting structure
The invention provides an overlapped semi-rigid pile plate node connecting structure. According to the connecting structure, pile plate nodes are effectively connected through connecting belts between adjacent prefabricated pavement slabs and combined connecting pieces between pile plates; the combined connecting piece between the pile plates comprises a prefabricated pile overlapping type end head, a first anti-vibration pad, a prefabricated section steel overlapping type connecting device, a second anti-vibration pad, a high-strength bolt, an unbonded prestressed steel bar and a plurality of prestressed steel bar anchorage devices. The prefabricated pile laminated end head is mounted at the top end of the prefabricated pile and is upwards and sequentially connected and fixed with the first anti-vibration pad and the prefabricated profile steel laminated connecting device through high-strength bolts; the prefabricated profile steel overlapping type connecting device is sequentially connected with the second anti-vibration pad and the connecting belt between the adjacent prefabricated pavement slabs upwards through unbonded prestressed steel bars, and the ends of the prefabricated profile steel overlapping type connecting device are fixed through a plurality of prestressed steel bar anchorage devices to form a whole. By means of the method, the assembly construction efficiency, the node energy dissipation capacity and the reusability of pile plate node connection are greatly improved.
本发明提出一种叠合式半刚性的桩板节点连接结构，该连接结构通过相邻预制道面板之间的连接带和桩板之间的组合连接件实现桩板节点有效连接；桩板之间的组合连接件包括预制桩叠合式端头、第一减振垫、预制型钢叠合式连接装置、第二减振垫、高强螺栓、无粘结预应力钢筋和若干预应力钢筋锚具；所述预制桩叠合式端头安装于预制桩顶端，向上依次与第一减振垫、预制型钢叠合式连接装置通过高强螺栓连接固定；所述预制型钢叠合式连接装置向上依次与第二减振垫、相邻预制道面板之间的连接带通过无粘结预应力钢筋连接，且在端部通过若干预应力钢筋锚具进行固定，形成整体。本发明的应用极大地提高了桩板节点连接的装配施工效率、节点耗能能力和复用性。
