框架梁柱钢筋绑扎安装工程的控制要点

Control Points of Binding Installation Engineering of Framework Beam Reinforcing Steel Bar

针对基础、框架梁、板、柱钢筋绑扎安装容易出现的问题,主要论述了桩顶纵筋在承台内的锚固构造;基础中柱插筋锚固构造;基础梁与楼层框架梁箍筋加密的区别;框架梁、柱纵筋在不同节点的锚固要求;框架梁、板、柱钢筋的连接方式、接头位置、接头数量、接头面积百分率;箍筋加密范围等。钢筋绑扎工程质量将直接影响到主体结构的安全,要控制好钢筋隐蔽工程项目的质量验收,保证主体结构工程质量的安全。

According to the foundation, frame beam, plate and column steel bar installation prob- lems easy to occur , this article mainly discusses the longitudinal reinforcement in pile cap within the an- choring structure; foundation column anchor structure; the differences between foundation beam and floor trame beam stirrup encrypts; the anchorage requirement of frame beam and column longitudinal steel bars in different nodes ; the connection mode, joint position, joint number and joint area percentage of frame beams, plates and columns reinforcement; stirrup encrypts range, etc. Reinforcing bar engi- neering quality will directly affect the main structure safety, so constructors should control the quality acceptance of the reinforcement＇s hidden project, to ensure the safety of the main structural engineering quality.
