整体提升脚手架内力计算

由于建筑物的形状不同，在建筑施工过程中所用的整体提升脚手架的布置也就不同，从而造成了整体提升脚手架在实际运用中内力的差异。基于这种原因，本文通过对整体提升脚手架设计方法的研究，建立了三跨连续梁的力学模型，分析了其受力特性，对脚手架在实际布置的最恶劣工程中所受到的各种载荷进行分析，从而得到了整体提升脚手架内力的一般求解方法。把上述方法求解出的各种载荷下的内力进行组合，即可用于验证脚手架的安全性。本文所述方法在脚手架设计时具有通用性。

The Internal Force Calculation of the Whole-Raising-Scaffold

Because of the different configurations of buildings to be constructed, the arrangement of the whole-raising-scaffold used for practical construction is not always the same, which results in difference of the internal force of the whole- raising-scaffold in application. Based on the abovementioned, in this paper, the design method of the whole-raising-scaffold is investigated, a mechanical model based on the three-span continuous beam is set up, the mechanical characteristics due to the action of various load of the whole-raising-scaffold under the worst working condition is analyzed. Then the calculating method for the internal force of its main structure can be found. Combining the internal force calculated by this method, the security of the scaffold can be verified. The method introduced by this paper can be used as a general method for the scaffold design.
