砖混结构中构造柱圈梁施工质量控制

The construction quality control of the constructional columns and the circle beams in brick masonry structure

砖混结构中构造柱和圈梁对结构抗震性能起着举足轻重的作用 ,在施工过程中 ,因思想不重视 ,造成了构造柱钢筋纵筋移位 ;混凝土底部马牙槎洞内漏振 ,构造柱连接处有断点 ;砌筑马牙槎尺寸、高度、位置等留设不规范。造成了圈梁模板拆后梁有凸肚、翘曲 ;混凝土梁柱节点振捣不密实等。针对上述质量问题 ,进行了原因分析 。

The constructional columns and the circle beams act important roles in the brick masonry structure for structural earthquake resistance. In the construction the vertical bars of constructional columns deviate and breakpoint exit in the connection of constructional columns. The dimension, height and position of combed joints are not standard. According to those problems the paper analyzes the reasons and proposes the controlling measures.
