钢筋混凝土构件粘钢加固技术及应用

Reinforcing technology and application of RC members with steel plates

我国在 2 0世纪七八十年代修建的建筑标准都比较低 ,随着时间的推移 ,这些旧建筑出现了不同程度的劣化 ,需要进行维修加固处理的建筑越来越多 .通过对正阳县第一小学教学楼悬挑梁的加固 ,介绍了钢筋混凝土构件外部粘钢加固技术的原理及其在工程实践中的设计思路、施工要点、技术措施等 ,可供类似工程设计。

In 1970s,1980s,some old buildings have deteriorated as time passed.So buildings which should be strengthened are becoming more and more.Through the reinforcing application of the cantilvever beams of the classroom building in the 1st Primary School of Zhengyang,the reinforcing technology and its design methods,construction attention and technical measures have been introduced.These can give some suggestion to the similiar egineering design and construction.
