针对实际施工中对扫地杆是否搭设和搭设质量的忽视,在实验室搭设高度为4.0m,3×3跨,跨度0.95m,步距1.3m的满堂扣件式钢管脚手架竖向加载的实体实验,通过设置纵横向扫地杆,去除横向扫地杆,再去除纵向扫地杆分析对架体承载力影响,并与ANSYS有限元模拟结果对比分析,得出去除扫地杆对脚手架立杆承载力有明显影响,所以实际工程中要高度重视扫地杆对架体的影响,此实验结论为现场搭设架体的技术人员提供借鉴。
In view of the negligence of whether the erecting poles are erected and erected in the actual construction, the full-scale fastener-type steel pipe scaffolding with a height of 4.0m, a span of 3 × 3, a span of 0.95m and a step distance of 1.3m By setting the vertical and horizontal sweeping poles, removing the horizontal sweeping poles and removing the influence of longitudinal sweeping pole analysis on the bearing capacity of frame, the results of ANSYS finite element simulation results show that removing the sweeping poles has a significant effect on the bearing capacity of the scaffolding poles , So the actual project should attach great importance to the impact of sweeping the pole on the frame, the experimental conclusion for the scene set up to provide technical support for the frame body.
