加大截面法加固钢筋混凝土框架柱实例

钢筋混凝土构件出现质量问题后,框架结构的安全性将受到严重威胁,必须进行及时处理。就某中学教学楼扩建工程钢筋混凝土框架柱的承载力不足构件的外观、钢筋分布和混凝土质量进行了调查,对构件的承载力和可靠性进行了评估,经过方案比选,采用加大截面法进行补强加固处理。文章详细介绍了设计方案和施工要点。实践证明。加固效果良好。

A Brotice to Reinforce a Reinforced Concrete Frame Column by Enlargement Section Method

If reinforced concrete structural components emerge quality failures, the structural safety will suffer the serious threat, so these failures must be handled on time. After detecting the exterior, distribution of reinforcing bars and quality of concrete of a capacity lack member in a middle school teaching house extension project, we accessed its capacity and safety. By comparing and contrasted many plans, we chose the enlargement section method to reinforce it. Some significant details including plan and construction were introduced in this paper. It was a fact that the reinforcement has gained good effect and notable economic bene-fit.
