Fabricated concrete shear wall local prestress connecting structure
The invention discloses a fabricated concrete shear wall local prestress connecting structure. The fabricated concrete shear wall local prestress connecting structure comprises a prefabricated concrete shear wall, wherein tie bars are arranged on the prefabricated concrete shear wall, and a lower end component is arranged at the bottom of the prefabricated concrete shear wall. According to the fabricated concrete shear wall local prestress connecting structure, a traditional steel sleeve grouting mode is abandoned, a prestressed steel bar tensioning mode is adopted, under the condition that the material consumption is far less than the material consumption of the steel sleeve grouting mode, the joint bearing capacity is close to or even larger than the bearing capacity improved through thesteel sleeve grouting mode, and the economy and the safety are achieved; and the stress of the middle of the connecting part between the prefabricated concrete shear wall of the fabricated concrete shear wall local prestress connecting structure and the foundation is less than the stress of the outer side, so that the prestress tensioning mode does not need to be adopted, steel fiber reinforced concrete shear key blocks are adopted, prestress high-strength steel bars and epoxy resin are inserted to serve as grouting materials, the connection mode is selected by fully combining a structural stress mode, the manufacturing cost is reduced, and the construction is easy.
本发明公开了一种装配式混凝土剪力墙局部预应力连接结构，包括预制混凝土剪力墙，所述预制混凝土剪力墙上设置有拉结筋，且预制混凝土剪力墙底部设置有下端构件。本装置摒弃传统钢套筒灌浆方式，采用预应力钢筋张拉方式，在材料用量远小于钢套筒灌浆方式所用材料的情况下，接缝承载力接近甚至大于钢套筒灌浆方式提高的承载力，经济又安全；该装配式混凝土剪力墙局部预应力连接结构的预制混凝土剪力墙与和基础连接部分的中部由于受力小于外侧，故无必要采用预应力张拉方式，改为采用钢纤维混凝土剪力键块，并插入预应力高强钢筋和环氧树脂作灌浆料，充分结合结构受力模式选择连接方式，减少造价并易于施工。
