Novel dry connection self-resetting node and manufacturing method
The invention discloses a novel dry connection self-resetting node and a manufacturing method, the self-resetting node comprises a prefabricated stand column and a prefabricated cross beam, the prefabricated cross beam is internally provided with a reserved hole for inserting an unbonded prestressed tendon, the end face of the prefabricated cross beam is fixedly provided with a beam shoe, the inner side of the beam shoe is provided with an inner nut, and the outer side of the beam shoe is provided with an outer nut; couplers are arranged at the corresponding positions in the prefabricated stand columns, and the inner nuts and the outer nuts on the beam shoes are connected with the couplers in the prefabricated stand columns through bolt rods. The low-yield-point bolt is used for replacing a traditional steel bar to serve as a self-resetting joint energy dissipation component, the construction process can be simplified, construction is easy and convenient, connection can be completed through few workers on site, temporary supporting is not needed, anti-torque connection can be formed once a nut is fastened, the bolt is easy to replace after an earthquake, and the construction cost is reduced. And compared with friction energy consumption, the metal yield energy consumption effect is more stable, and the node structure is simple.
本发明公开一种新型干连接自复位节点及制作方法，自复位节点包括预制立柱和预制横梁，预制横梁内设置有用于穿插无粘结预应力筋的预留孔洞，预制横梁端面固定设有梁靴，梁靴内侧设置有内螺母，梁靴外侧设置有外螺母，预制立柱内设置有对应位置设置有耦合器，梁靴上的内螺母、外螺母与预制立柱内的耦合器之间通过螺栓杆连接。本发明使用低屈服点螺栓来代替传统钢筋作为自复位节点耗能部件，能够简化施工流程，使得施工简捷，现场需要很少的工人即可完成连接，而且不需要临时支撑，一旦螺母紧固就可以形成抗力矩的连接，且震后螺栓易更换，减少了修复费用成本，用金属屈服耗能效果相对摩擦耗能更稳定，节点构造简单。
