摘要:目前, 在新建房屋及旧房改造中, 有关悬挑结构倾覆、坍塌的事故时有发生, 从悬挑结构坍塌实例来看, 表现为三种形式: 整体倾覆坍塌、沿悬臂梁根部的断塌及悬挑构件下砌体局部受压破坏. 本文从设计、施工及使用角度系统地分析了悬挑结构坍塌事故发生的原因, 如采用不正确的计算方法、模板支撑方案不当、施工超载、拆模过早、不正确地使用等, 并对这些原因提出了切实可行的防治措施和处理方法.

The Causes of the Overhanging Structure Collaping and Its Countermeasure

Abstract:Some accidents of overhanging structure collaping have frequently occurred in the new or old buildings. The accidents have three forms, that is, whole overhanging, breaking in the root of cantilever beam, and partly compression destruction of the masonry. A systematic analysis of the causes of the accidents of overhanging structure due to the design, construction and residing, such as using incorrect calculating method, unfitting formwork supports, construction overloads, form removal too early, uncorrect using and some others have been stated. Therefore, several prevention and control measures have presented for a consideration.
