Fabricated concrete frame structure system with joints connected by UHPC (Ultra High Performance Concrete)
The invention discloses a fabricated concrete frame structure system with joints connected through UHPC. The fabricated concrete frame structure system comprises a prefabricated concrete beam, a first-layer prefabricated concrete lower column, a first-layer prefabricated concrete upper column, a second-layer prefabricated concrete column and a prestressed steel pipe truss floor support plate. A post-cast UHPC column-column node area is arranged at the joint of the first-layer prefabricated concrete lower column and the first-layer prefabricated concrete upper column; a post-cast UHPC beam-column node area is arranged at the joint of the second-layer prefabricated concrete column, the first-layer prefabricated concrete upper column and the prefabricated concrete beam; the tops of the adjacent precast concrete upper columns are connected with precast concrete beams; and the prestressed steel pipe truss floor support plates are uniformly distributed in a horizontal area defined by the precast concrete beams. The prefabricated assembly type structural system is short in engineering period, good in anti-seismic performance and easy to maintain and repair, and the assembly efficiency and the bearing capacity and the shear capacity of the prefabricated concrete column are improved.
本发明公开了一种节点采用UHPC连接的装配式混凝土框架结构体系，包括预制混凝土梁、一层预制混凝土下柱、一层预制混凝土上柱、二层预制混凝土柱、预应力钢管桁架楼承板；一层预制混凝土下柱、一层预制混凝土上柱连接处为后浇UHPC柱‑柱节点区；二层预制混凝土柱、一层预制混凝土上柱和预制混凝土梁的连接处为后浇UHPC梁‑柱节点区；相邻预制混凝土上柱顶部连接预制混凝土梁；预制混凝土梁之间围成的水平区域内均布设预应力钢管桁架楼承板。本发明是具有工程周期短、良好抗震性能、易于维护和修复的预制装配式结构体系，提高了装配效率及预制混凝土柱的承载能力和抗剪能力。
