Abstract:

A standardized foldable variable height lightweight operating frame for construction has beendesigned. Through theoretical calculations and numerical simulations, the horizontal bar force,verticalpole axial force, and anti overturning stability calculation, as well as the overall force and instabilityanalysis of the folding frame, have been carried out to ensure the safety and reliability of the structure.By using aluminum alloy materials and arranging ladder openings reasonably, the problems of complex,heavy, difficult ladder installation, and personnel difficulty in operating scaffolding such as steel pipefastener scaffolding and plate fastener scaffolding can be solved. Through the bottom support, the safetyrisk of easy overturning of the climbing operation frame and the illegal operation risk caused by the bottomrolling wheel are solved, and the structural stability is increased by setting slant support. Combiningeconomy analysis, this paper compares the number of upright poles of steel pipe buckle operating framesunder the same conditions. The research results indicate that with the increase of turnover times, the newoperating frame can significantly reduce manual installation time and achieve cost reduction and efficiencyimprovement.
