Fabricated beam-column joint
The invention relates to a fabricated beam-column joint, which belongs to the technical field of beam-column connecting structures and comprises a concrete column, a concrete beam is horizontally arranged on one side of the concrete column, and two beam end side plates are vertically arranged on two sides of one end, close to the concrete column, of the concrete beam. The two column end side plates are horizontally arranged outside the sides, away from the concrete beam, of the two beam end side plates, the two fixing plates are vertically arranged between the two beam end side plates and the two column end side plates correspondingly, and the U-shaped energy dissipation plates are vertically arranged on the upper side and the lower side between the two fixing plates at equal intervals. The metal yield energy dissipation box is formed by the fixing plates and the U-shaped energy dissipation plates in the beam end side plate and the column end side plate, the metal yield energy dissipation box firstly yields under the action of a medium earthquake, the beam end corner is increased along with the increase of the earthquake action, the beam end side plate and the column end side plate generate rotary friction, and a friction energy dissipation stage is started; therefore, continuous energy dissipation from a middle earthquake to a large earthquake is achieved, and the anti-seismic performance of the assembly type beam column joint is improved.
本发明涉及一种装配式梁柱节点，属于梁柱连接结构技术领域，包括混凝土柱，混凝土梁水平设置在混凝土柱的一侧，两个梁端侧板竖直设置在混凝土梁靠近混凝土柱一端的两侧，两个柱端侧板水平设置两个梁端侧板远离混凝土梁的一侧外部，两个固定板分别竖直设置两个梁端侧板以及两个柱端侧板之间，多个U型耗能板等间距竖直设置在两个固定板之间的上下两侧，本发明通过梁端侧板、柱端侧板内部的固定板、U型耗能板构成金属屈服耗能箱，在中震作用下金属屈服耗能箱首先发生屈服，随着地震作用增大梁端转角加大，使得梁端侧板、柱端侧板发生旋转摩擦，进入摩擦耗能阶段，从而做到从中震到大震的连续耗能，提高装配式梁柱节点的抗震性能。
