对于有抗震要求的多层及高层框架的节点,钢筋安装工程常常存在这样的质量问题:一是框架节点处柱的箍筋远不能满足设计要求,甚至沿整个梁高范围内连一根柱箍都不绑扎。二是上层柱的纵向钢筋与下层柱钢筋搭接时,常因下层柱 For the nodes with multi-layer and high-rise frames that have seismic requirements, there are often such quality problems in the installation of steel bars: First, the stirrups at the frame joints are far from meeting the design requirements, even with a column hoop along the entire beam height range. No banding. The second is that when the upper column’s longitudinal reinforcement and the lower column’s reinforcement are overlapped, often due to the lower column
