摘　　要：某中心剧院项目采用劲性混凝土结构设计,劲性混凝土结构在梁柱核心区既要安装钢骨构件又要排布受力钢筋,核心区节点连接复杂,质量不易保证。为保证核心区复杂节点的施工质量,结合工程特点在梁柱节点核心区组合使用钢构件开孔穿筋(穿)、焊接机械连接套筒或与连接板焊接(焊)及钢筋并筋绕开(绕)的方式保证节点部位的施工质量。另外,从质量监督角度分析了多种钢筋连接方式的质量控制要点,进而提高监督检查针对性与有效性,促进项目提高施工质量。A theater was constructed in stiff concrete structure.Steel components and load-bearing reinforcing bars are installed in the core area of beam column.As a result,construction quality may not be ensured.Based on the characteristics of the project,steel bar interpenetration,welding of jackets or connecting plates and twin bars were used in the core area of beam columns to ensure construction quality.Quality control points of connecting mode of reinforcing bars were analyzed from the perspective of quality supervision in attempt to improve quality supervision and construction quality.

关 键 词：劲性结构节点 节点连接组合 质量控制点
