高边坡脚手架结构计算理论与方法概述
|
摘要
关于高边坡脚手架的结构计算却至今没有统一的计算方法,为此,结合当今研究的现状,对脚手架系统从单杆件计算到整体结构计算的理论进行详细的阐述及对比分析,并对脚手架的计算理论进行力学方面的探讨,对不同理论提供较为明确的计算简图和系统完整的分析和论证。通过对脚手架格构式体系、刚架结构、排架结构三种整体结构模式进行结构力学方面的对比分析以及相关力学的探讨,最终得出应尽量采用格构式体系进行脚手架设计和理论计算,并且提出采用电算方法是脚手架结构设计与计算的发展前景。
There is no unified calculation method about high slope scaffold structure.Combining with current researches,the calculation theories of scaffolding system from single bar to whole structure are compared and analyzed in detail,the calculation theories are also discussed from the aspect of mechanics,and clear calculation diagrams of different theories and corresponding system analysis and demonstration are finally provided.Three kinds of integral scaffold structures of lattice system,steel structure and bent structure are analyzed and compared from structural mechanics,and it is concluded that the lattice system should be used to carry out the design and theoretical calculation of scaffolding.The suggestion on the use of computer-based scaffolding structure design and calculation is also proposed.
