高层大悬挑结构施工技术的实施与监测分析

Implementation and Monitoring Analysis of Construction Technology for High-rise Large Cantilever Structures

为满足高层建筑多元化建设需求,大悬挑结构应运而生,此结构建设时具有较高的抗震抗风要求,但由于高层建筑层数多、高度大,高层大悬挑结构的稳定性控制难度越来越大。为此,文章结合高层建筑工程实例,介绍了大悬挑结构支撑体系设置方法,依次阐述了钢筋、模板、混凝土三项施工的技术要点,最后对支撑胎架展开了监测分析,得出本文采用的大悬挑结构施工技术在高层建筑施工中具有较高的应用价值。

In order to meet the diversified construction needs of high-rise buildings,large cantilever structures have emerged.This structure has high seismic and wind resistance requirements during construction.However,due to the multiple floors and high height of high-rise buildings,the stability control of large cantilever structures is becoming increasingly difficult.For this purpose,the article combines examples of high-rise building engineering to introduce the setting method of the large cantilever structure support system,and sequentially elaborates on the technical points of steel reinforcement,formwork,and concrete construction.Finally,monitoring and analysis of the support frame are carried out,and it is concluded that the construction technology of the large cantilever structure used in this article has high application value in high-rise building construction.
