Self-resetting assembly type reinforced concrete frame structure
The invention belongs to the technical field of assembly type buildings, and discloses a self-resetting assembly type reinforced concrete frame structure which comprises a plurality of prefabricated concrete columns which are vertically connected with one another, the prefabricated concrete columns are connected with prefabricated concrete beams through dampers of assembly energy dissipation nodes, and in-column embedded steel connecting pieces are embedded in the upper portions of the prefabricated concrete columns. And a column bottom embedded steel connecting piece is embedded at the bottom. Two energy dissipation structures of the dog bone type weakening steel plate and the multi-seam energy dissipation steel plate are arranged, replacement is very convenient and fast, the PVC pipes are embedded in advance before concrete beams and columns are poured, the steel strands penetrate through the reserved PVC pipes after forming, then the steel strands are tensioned to apply prestress, the steel strands in the columns and the steel strands in the beams both pass through the connecting joints, and the steel strands in the columns and the steel strands in the beams are connected through the connecting joints. Not only is the self-resetting capability provided, but also the connection strength of the node is enhanced; the structure is simple in construction, high in energy dissipation capacity, good in self-resetting performance and easy to repair, and the structure has excellent anti-seismic performance under high-strength earthquakes.
本发明属于装配式建筑技术领域，公开了一种自复位装配式钢筋混凝土框架结构，包括若干竖向相互连接的预制混凝土柱，预制混凝土柱通过装配耗能节点的阻尼器连接预制混凝土梁，预制混凝土柱上部预埋有柱中预埋钢连接件，底部预埋有柱底预埋钢连接件。本发明具有狗骨式削弱钢板和多缝耗能钢板两种耗能结构，更换十分便捷，在浇筑混凝土梁和柱之前预先埋设PVC管，待成型后将钢绞线贯穿预留PVC管，然后对钢绞线进行张拉施加预应力，柱内钢绞线和梁内钢绞线都经过连接节点，不仅提供自复位能力，还加强了节点的连接强度；本发明施工简单、耗能能力强、自复位性能好且易修复，使得结构在高强地震下具有优异的抗震性能。
