钢筋混凝土框架柱增层改造施工工艺研究

Study on construction technology of storey adding reinforcement of reinforced concrete frame column

直接在柱顶表面凿毛安装孔环形连接板,对钢管施加预应力,克服了常规施工方法施工过程中对梁体产生破坏,便于对施工控制,有很好的工程应用价值,可以为类似工程提供参考。

This paper is directly connected with the board in the top surface roughening the mounting hole ring of prestressed steel pipe. It over-comes the conventional construction method in the construction process of the beam damage, which is convenient for construction. So it has good engineering application value, which can provide reference for similar projects.
