Prestress self-adaptive hinged beam column joint, hinged system and construction method
The invention relates to the technical field of prefabricated concrete hinged joints, in particular to a prestress self-adaptive hinged beam column joint which comprises a bracket column, a beam column, a beam column, a beam column, a beam column and a beam column. The notched beam is matched with the middle column, and a groove, a hole channel and a rear pouring gate are reserved in the notched beam; the pin key rib is arranged on the bracket column, part of the pin key rib extends out of the bracket column, the pin key rib is inserted into the hole channel, the two ends of the prestressed rib extend into the notch beam and extend out of the rear pouring gate, and after the prestressed rib is stretched, high-strength shrinkage-free grouting materials are poured into the groove, the hole channel and the rear pouring gate; or, the notched beams are matched with the side columns, fixing pieces are arranged in the notched beams and on the sides, away from the notched beams, of the side columns, and the prestressed tendons are connected with the fixing pieces after being stretched; and the buffer piece is arranged between the bracket column and the notched beam. According to the prestress self-adaptive hinged beam column joint, the construction time is greatly shortened, the construction cost is greatly reduced, and the construction speed is effectively increased.
本发明涉及预制混凝土铰接节点技术领域，具体涉及一种预应力自适应铰接梁柱节点，包括：牛腿柱，包括中间柱或边柱，预应力筋贯穿牛腿柱；缺口梁，与中间柱相适配，且缺口梁上预留有凹槽和孔道、以及后浇口；销键筋，设于牛腿柱上，且部分伸出牛腿柱，销键筋插置于孔道内，预应力筋的两端伸入缺口梁，并由后浇口伸出，预应力筋拉伸后，对凹槽和孔道内、以及后浇口内灌入高强无收缩灌浆料；或，缺口梁与边柱相适配，缺口梁内部和边柱远离缺口梁的一侧均设有固定件，预应力筋拉伸后，与固定件连接；缓冲件，设于牛腿柱和缺口梁之间。该预应力自适应铰接梁柱节点使得施工时间和施工成本大大降低，并且施工速度得到了有效的提升。
