摘要
某低强度混凝土楼板须进行加固处理,因拆除重做极不经济,采用置换受压区混凝土并增设暗梁形成锚固键的方法加固楼板,解决了新旧混凝土结合层协同工作的问题,投入使用1年多未发现任何问题,加固效果良好。
As it is quite uneconomical to dismantle and reconstruct the low strength concrete slabs, they must be reinforced. By replacing compressive concrete and adding hidden-beam to form anchoring key, which enable the interface of the new and old concrete to function jointly, the slabs were strengthened. No problem has taken place more than one year since they were put into use, which shows that the reinforcement has achieved good result.
