框架结构梁柱节点是框架结构的关键部位,节点构造复杂,钢筋绑扎密集,而且都是高空作业,特别是中间柱子钢筋纵横交错,箍筋绑扎极为不便,给施工造成许多麻烦,稍有疏忽质量就难以保证。历次震害表明,框架结构的破坏绝大部分是由梁柱节点核心区强度不足和延性不够所致。所以在施工中应该提高对抗震节点重要性的认识,严格管理,采取合理的施工措施,确保施工质量能达到设计及规范的要求,不留隐患。对框架结构梁柱节点施工的具体方法进行讨论、总结,权当能为同行业者提供一个参考。
Frame structure The beam-column joint is the key part of the frame structure. The structure of the node is complex and the tendons are heavily lashed, and all are working at heights. In particular, the columns of the middle column are criss-crossing in length and breadth and the stirrups are bound in a very inconvenient manner. It is difficult to guarantee. The previous earthquake damage shows that most of the damage to the frame structure is caused by insufficient strength and ductility of the core region of the beam-column joints. Therefore, it is necessary to raise awareness of the importance of anti-seismic nodes during construction, strictly manage and take reasonable construction measures to ensure that the construction quality can meet the requirements of design and norms without leaving hidden dangers. Discuss and discuss the concrete methods of construction of beam-column joints in frame structure, and provide a reference for the same industry.
