Description
技术领域technical field
本实用新型涉及建筑结构技术领域，尤其涉及一种装配整体式梁柱节点。The utility model relates to the technical field of building structures, in particular to an assembled integral beam-column joint.
背景技术Background technique

This type of structural system has the advantages of fast construction speed, low environmental pollution, guaranteed quality and good durability.
预制混凝土梁与预制混凝土柱的节点连接构造质量直接影响到该类结构的极限承载力和抗震性能。目前已有的预制框架结构梁柱节点连接技术将梁端设有键槽或U形凹槽，同时配有普通钢筋与U型钢筋，相互搭接、锚固于节点核心区内，并在节点区的后浇段采用混凝土现浇将预制混凝土梁、柱形成一个整体。以上预制框架梁柱节点连接技术具有适用性不足、施工建造不便等问题，这使得预制预应力混凝土装配整体式框架结构的应用优势并不明显。The structural quality of joint connections between precast concrete beams and precast concrete columns directly affects the ultimate bearing capacity and seismic performance of this type of structure. At present, the existing prefabricated frame structure beam-column joint connection technology is provided with keyway or U-shaped groove at the end of the beam, and is equipped with ordinary steel bars and U-shaped steel bars, which are overlapped and anchored in the core area of the joint, and in the joint area. The post-casting section uses concrete cast-in-place to form a whole of precast concrete beams and columns. The above prefabricated frame beam-column joint connection technology has problems such as insufficient applicability and inconvenient construction, which makes the application advantages of prefabricated prestressed concrete assembly integral frame structure not obvious.
如何构建受力性能良好、构造措施合理、施工便捷的新型梁柱节点连接构造，一直是预制预应力混凝土装配整体式框架结构的技术难点。How to construct a new beam-column joint connection structure with good mechanical performance, reasonable structural measures, and convenient construction has always been a technical difficulty in the precast prestressed concrete assembly integral frame structure.
