摘要
在一些重大项目中,高强混凝土的采用使得部分框架柱与框架梁的混凝土强度等级并不相同。在设计中,一般将梁柱节点区域的混凝土按照高强度等级的混凝土进行浇筑,由此带来的问题是:该节点区域的混凝土浇筑困难,特别是对于大截面的梁柱构件来说,梁板混凝土与节点区域混凝土分开浇筑将很难保证施工质量。对梁柱节点区域的混凝土实际表现强度进行了对比分析,对该区域等强处理方法和措施给出了建议。
In some major projects,due to the using of high-strength concrete the concrete strength grade of frame column and beam is not different. The high-grade concrete is often used to pouring into the beam-column joints in the design,and which will lead to some problems. Concrete pouring of beamcolumn joints is very difficult especially for large section member. Construction quality control will be difficult due to pouring separately of members and beam-column joints concrete. Concrete representative strength of beam-column joints is analyzed in this paper. The equal-strength processing methods and measures are given.
