【摘要】：满堂扣件式钢管脚手架在混凝土工程模板施工中有着广泛的应用,具有拆装方便、周转次数多、经济效益显著等诸多优点。本文通过3×3跨的满堂式扣件钢管脚手架加载实验,在施加不同荷载的情况下,研究脚手架某一立杆扣件处的应力传递规律。采用数值模拟和现场监测等分析方法,分析在不同的荷载作用下,架体内部钢管立柱的应力传递规律,其结论和研究方法可为研究类似架体的受力性能提供借鉴和参考,同时为现场关键点监控和远程安全预警系统开发提供相应的理论依据。
[Abstract]:The scaffolding of steel tube with full hall fastener is widely used in the construction of concrete engineering formwork. It is convenient to disassemble and assemble, and has a lot of turnover times. In this paper, through the 3 脳 3 span full buckle steel tube scaffolding loading experiment, under the condition of different load. This paper studies the stress transfer law of a vertical rod fastener of scaffold, and analyzes the stress transfer law of steel tube column in the frame under different loads by numerical simulation and field monitoring. The conclusion and research method can provide reference and reference for studying the mechanical performance of similar frame, and also provide the corresponding theoretical basis for the development of monitoring and remote security early warning system at key points in the field.
