Composite semi-rigid pile plate joint connecting structure and construction method
The invention relates to a combined type semi-rigid pile plate joint connecting structure and a construction method.The combined type semi-rigid pile plate joint connecting structure comprises a connecting area and a combined connecting piece between pile plates, and the connecting area comprises reserved steel bars, long bolts, post-pouring concrete and plate top negative steel bars; the combined connecting piece comprises a prefabricated pile end plate, a prefabricated base plate, a prefabricated steel casing, a gasket leveling layer, an energy-consuming reinforcing steel bar, a prestressed reinforcing steel bar and in-casing concrete filled in the prefabricated steel casing, and the upper end of the energy-consuming reinforcing steel bar and the upper end of the prestressed reinforcing steel bar are both fixed to the gasket leveling layer. The nut end of a long bolt is arranged on the lower surface of the gasket leveling layer, the other end of the long bolt is fixed through a long bolt matched nut located on the upper surface of the gasket leveling layer, and the slab end of the prefabricated pavement slab is fixed to the gasket leveling layer in a lap joint mode. According to the invention, the occurrence of structural cracking is reduced, the power damage of the pile plate joint under the action of dynamic load is greatly reduced, and the earthquake energy dissipation capacity of the pile plate structure is improved.
本发明涉及一种复合式半刚性的桩板节点连接结构及施工方法，其中，复合式半刚性的桩板节点连接结构，包括连接区和桩板之间的组合连接件，连接区包括预留钢筋、长螺栓、后浇混凝土和板顶负筋，组合连接件包括预制桩端板、预制垫板、预制钢护筒、垫圈调平层、耗能钢筋、预应力钢筋以及填充在预制钢护筒内的筒内混凝土，耗能钢筋的上端和所述预应力钢筋的上端均固定在所述垫圈调平层上，长螺栓的螺帽端在所述垫圈调平层的下表面，另一端用位于垫圈调平层上表面的长螺栓配套螺母固定，预制路面板板端搭接固定在所述垫圈调平层上。本发明减小了结构开裂情况的发生，极大地降低了桩板节点在动荷载作用下的动力损伤，提高了桩板结构的地震耗能能力。
