Fabricated self-resetting reinforced concrete beam-column connecting joint and construction method
The invention discloses an assembly type self-resetting reinforced concrete beam-column connecting joint and a construction method. The joint comprises a prefabricated concrete column and a prefabricated concrete beam, and a beam-column joint embedded part is arranged on the prefabricated concrete column; a beam end embedded part is arranged at the end of the prefabricated concrete beam, and one end of the beam column joint embedded part is located in an inner cavity of the connecting steel sleeve. Self-resetting connecting pieces are arranged on the upper side and the lower side of the beam end embedded part, and the self-resetting connecting pieces are fixedly connected through the vertical opposite-pulling anchor rods and the transverse opposite-pulling anchor rods; a buffer cushion layer is arranged between the precast concrete beam and the precast concrete column; the method comprises the steps of prefabricated part manufacturing, prefabricated concrete column and prefabricated concrete beam manufacturing, self-resetting connecting part installation and beam column connection. The joint can effectively reduce the residual strain of the structure, improve the anti-seismic toughness of the structure and reduce the post-earthquake loss of the building structure, the structure is simple and compact, the connection strength is high, welding on the construction site is not needed in the method, and the construction efficiency is improved.
本发明公开了一种装配式自复位钢筋混凝土梁柱连接节点及施工方法，该节点包括预制混凝土柱和预制混凝土梁，在预制混凝土柱上设置有梁柱节点预埋件；在预制混凝土梁的端部上设置有梁端预埋件，梁柱节点预埋件的一端位于连接钢套的内腔中；在梁端预埋件的上下两侧设置有自复位连接件，自复位连接件通过竖向对拉锚杆及横向对拉锚杆固定连接；在预制混凝土梁与预制混凝土柱之间设置有缓冲垫层；该方法包括预制件制作、预制混凝土柱与预制混凝土梁的制作、安装自复位连接件及梁柱连接。该节点能够有效降低结构的残余应变，增加结构的抗震韧性，减少建筑结构的震后损失，结构简单紧凑，连接强度高，该方法无需在施工现场焊接，提高了施工效率。
