无梁楼盖节点加固实用技术

Reinforcing Technology of No-beam Floor

如果无梁楼盖发生冲切破坏,将发生楼板整体塌落、结构柱穿透混凝土楼板的工程事故。导致这些事故的原因主要为设计和施工阶段的失误以及使用情况的改变等。可以通过结构加固的方法避免此类事故的发生,重点介绍了无梁楼盖节点的加固技术。

If no-beam floor is damaged by an action known as punching, the construction accident will occur that some building floors collapse and the supporting columns break through the concrete slab. The main factors, which cause these accidents, are failure at the design and construction stage and change of working condition. They can be avoided by structure strengthening method. In this article, the author mainly shows strengthening technologies of no-beam floor.
