摘　　要：箱型钢柱与钢筋混凝土梁是大型公共建筑常用的结构体系,然而现有施工工艺容易在梁柱核心区产生梁纵向钢筋连接不牢及混凝土孔洞外观缺陷等质量问题。论文以一实际工程为背景对箱型钢柱与混凝土梁连接节点施工合格率进行调查研究,查找了箱型钢柱与混凝土梁连接节点施工合格率不高的原因,提出了新型施工方法并通过在该项目中的具体实施,验证了所提方法的有效性。Box shaped steel columns and reinforced concrete beams are commonly used structural systems in large public buildings.However,existing construction techniques are prone to quality problems such as weak longitudinal steel bar connections and appearance defects of concrete holes in the core area of the beams and columns.This article investigates and studies the construction qualification rate of connection nodes between box shaped steel columns and concrete beams based on an actual project.The reasons for the low construction qualification rate of connection nodes between box shaped steel columns and concrete beams are identified,and a new construction method is proposed.The effectiveness of the proposed method is verified through specific implementation in this project.
