Connecting method for fabricated concrete beam-column dry-type joints
According to the connecting method of the assembly type concrete beam column dry type joint, high-strength finish rolling deformed steel bars are adopted, reserved holes of a concrete column are utilized, and dry type connection mainly including non-bonding, weak bonding and the like is carried out. Wherein the column is a concrete cast-in-place column or a prefabricated column with a bracket, and the column and the prefabricated beam can be conveniently spliced and mounted on site, applied with pre-stress and replaced and repaired after an earthquake through finish rolling deformed steel bars. Meanwhile, the brackets are arranged on the two sides of the column, so that vertical loads are conveniently borne, and vertical shearing force is conveniently transmitted. By applying pre-tension stress to the high-strength finish-rolled deformed steel bars and applying special shear-resistant devices at the two ends, good overall performance and rigidity of the fabricated beam-column joint under the normal use load can be provided, and meanwhile large elastic deformation is provided by means of non-bonding between the finish-rolled deformed steel bars and concrete in the column; the good deformation capacity and displacement recovery capacity of the structure under the accidental action are provided, and the convenience of post-earthquake repair of the assembly type joint is greatly improved.
一种装配式混凝土梁柱干式节点的连接方法，采用高强精轧螺纹钢，利用混凝土柱的预留孔洞，实行无粘结、弱粘结等以干式连接为主的方式。其中柱为带牛腿的混凝土现浇柱或预制柱，柱和预制梁通过精轧螺纹钢可实现便捷的现场拼接安装、预加应力施加、震后更换修复。同时在柱两侧通过牛腿，便于承载竖向荷载传递竖向剪力。本发明通过对高强度精轧螺纹钢施加预拉应力及两端特殊的抗剪装置，可提供在正常使用荷载下装配式梁柱节点良好的整体性能和刚度，同时依赖精轧螺纹钢与柱内混凝土之间的无粘结提供较大的弹性形变，提供在偶然作用下该结构良好的变形能力及位移恢复能力，本发明还极大的提升了装配式节点震后修复的便捷性。
