Post-tensioned prestressed fabricated frame joint and construction method thereof
The invention provides a post-tensioned prestressing fabricated frame node and a construction method thereof. The post-tensioned prestressing fabricated frame node comprises a prefabricated column, the prefabricated column is provided with a bracket, and the bracket is provided with a concrete overhanging plate serving as a tenon of a mortise and tenon joint structure; the precast beam is arranged on the bracket of the precast column; a beam end notch is formed in the precast beam to serve as a tenon eye of a tenon-and-mortise structure, and the tenon head and the tenon eye are in contact and support with each other; every two adjacent prefabricated beams are connected and fixed to the prefabricated columns in the mode that prestressed steel bars penetrate through the prefabricated columns; the metal elastic gaskets are arranged on the two sides of the prefabricated column and abut against the corresponding prefabricated beams; one limb of the energy dissipation angle steel is fixedly connected with the prefabricated column, and the other limb of the energy dissipation angle steel is fixedly connected with the prefabricated beam. Through the synergistic effect of the two energy consumption components of the tenon-and-mortise joint and the energy consumption angle steel, the node earthquake resistance of the assembly type frame structure is improved.
本发明提供的一种后张预应力装配式框架节点及其施工方法，包括预制柱，所述预制柱上带有牛腿，所述牛腿上设有混凝土外伸板作为榫卯结构的隼头；预制梁，设于预制柱的牛腿上；所述预制梁上开设有梁端切口作为榫卯结构的隼眼，所述隼头和隼眼相互接触支撑；且两相邻所述预制梁之间通过预应力钢筋穿过预制柱相连接固定于所述预制柱上；金属弹性垫片，设于预制柱两侧，且与相对应的预制梁相抵接；以及耗能角钢，一肢与预制柱固定连接，另一肢与预制梁固定连接。本发明通过通过榫卯和耗能角钢两种耗能构件协同作用，提高装配式框架结构的节点抗震性。
