Fabricated concrete frame beam-column dry type connecting joint adopting bolt connection
The invention discloses a fabricated concrete frame beam-column dry type connecting joint adopting bolt connection. The fabricated concrete frame beam-column dry type connecting joint comprises a prefabricated concrete column, a prefabricated concrete beam and two L-shaped connecting devices, each L-shaped connecting device comprises a vertical plate and a transverse plate, and the two L-shaped connecting devices are symmetrically arranged at the upper side and the lower side of the end part of the prefabricated concrete beam; and the two transverse plates are fixedly connected with the upperside and the lower side of the prefabricated concrete beam, the two vertical plates are fixedly connected with one side face of the middle of the prefabricated concrete column, two steel plates arranged on the side faces of the ends of the prefabricated concrete beam are also included, and the two steel plates and the two transverse plates are welded to form a wrapping cavity to wrap the end of the prefabricated concrete beam insides. According to the fabricated concrete frame beam-column dry type connecting joint, the L-shaped steel plates are adopted at the beam-column joint for high-ductility bolt connection, the energy dissipation capacity of the joint can be effectively improved, meanwhile, the prefabricated concrete beam is wrapped with the steel plates, the strength of the part canbe enhanced, outward movement of beam-end plastic hinges is achieved, and the deformation capacity of the joint is enhanced.
本发明公开一种采用螺栓连接的装配式混凝土框架梁柱干式连接节点，包括预制混凝土柱、预制混凝土梁、两个L型连接装置，L型连接装置包括竖板和横板，两个L型连接装置对称的设在预制混凝土梁端部的上下两侧，且两个横板与预制混凝土梁上下两侧连接固定，两个竖板与预制混凝土柱中部一侧面连接固定，还包括设在预制混凝土梁端部侧面的两块钢板，两块钢板与两块横板焊接形成包覆腔将预制混凝土梁端部包裹在内。本发明在梁柱连接处采用L型钢板进行高延性螺栓连接，能够有效提高节点的耗能能力，同时在预制混凝土梁外部包上钢板，可以增强该部分的强度，实现梁端塑性铰外移，增强节点变形能力。
