Semi-rigid connection precast concrete frame structure
The invention discloses a semi-rigid connection precast concrete frame structure, which is characterized by comprising a precast concrete column, a precast concrete beam, a precast concrete node core area and a post-pouring concrete laminated layer, the prefabricated concrete column on the upper portion and the prefabricated concrete column on the lower portion are connected through a screw connector and a high-strength screw, no rib is exposed out of the column end, the prefabricated concrete column and the prefabricated concrete beam are connected through a convex connector and a concave connector, no rib is exposed out of the beam end, and UHPC grouting is adopted in a cavity of the connector. According to the invention, the construction is convenient and fast, the quality is controllable, the on-site wet operation can be reduced, the assembly rate is improved, the bearing capacity level is high, meanwhile, the semi-rigid characteristic is obvious, the deformation capacity of the node is greatly improved, and the construction period is shortened. The method has important significance in improving the construction efficiency and the engineering quality of the precast concrete structure, and has wide application prospects in the field of constructional engineering.
本发明公开了一种半刚性连接预制混凝土框架结构，具有这样的特征，包括：预制混凝土柱、预制混凝土梁、预制混凝土节点核心区以及后浇混凝土叠合层，其中，上部的预制混凝土柱和下部的预制混凝土柱之间通过螺杆连接器和高强螺杆相连接，柱端不出筋，预制混凝土柱和预制混凝土梁之间在通过凸形连接器和凹形连接器连接，梁端不出筋，并在连接器空腔处采用UHPC灌浆，后浇混凝土叠合层在预制混凝土梁上，本发明施工便捷、质量可控，可减少现场湿作业、提高拼装速率，承载力水平高，同时具有明显的半刚性特征，大大提高了节点的变形能力，本发明对于提高预制混凝土结构的建造效率和工程质量具有重要意义，在建筑工程领域中具有广阔的应用前景。
