在结构质量事故中,现浇钢筋混凝土檐板根部顺墙断裂所占比例很大。造成这种事故的原因很多,其中一个主要原因是主筋位置不正确,未放在板的上部,位置偏低,或是在施工中主筋被踩后未及时扶正,降低了有效高度,削弱了板的强度。在处理这类事故时,一般是打掉重做。但有时由于情况复杂,不允许打掉重做,这就需要加固补强。本文介绍两种简易的加固补强方法。
In the structural quality accidents, the proportion of in-situ reinforced concrete rafts along the root wall is very large. There are many reasons for this type of accident. One of the main reasons is that the main ribs are not positioned correctly, they are not placed in the upper part of the board, the position is low, or the main ribs are not stepped up right after being stepped on, reducing the effective height and weakening the board. Strength of. In dealing with such accidents, it is usually done to re-do. However, sometimes due to the complexity of the situation, it is not allowed to eliminate re-doing, which requires reinforcement and reinforcement. This article describes two simple reinforcement methods.
