摘要: 針對整體鋼平臺模架與大型垂直運輸塔機等施工機械一體化集成要求,基于模塊化設(shè)計的理念,通過局部強化、整體輕量化的思路建立了臨時鋼結(jié)構(gòu)支撐體系,同時運用結(jié)構(gòu)分析軟件對結(jié)構(gòu)進行整體優(yōu)化。 通過控制作業(yè)階段和爬升階段時的受力構(gòu)件應(yīng)力比、最大變形、豎向及側(cè)向支撐裝置反力,從而滿足承載力要求。 結(jié)果表明:臨時鋼結(jié)構(gòu)支撐體系通過在集成部位局部采用高承載力筒架支撐結(jié)構(gòu)與高承載力鋼梁爬升結(jié)構(gòu)的方式,從而解決大型機械設(shè)備的荷載傳遞問題,并在大噸位液壓油缸驅(qū)動下通過二者的交替支撐實現(xiàn)自動爬升。

Abstract: In view of the integration requirements of the overall steel platform formwork and construction machinery such as large vertical transport tower cranes, based on the concept of modular design, a temporary steel structure support system was established through the idea of local strengthening and overall light weight. At the same time, the structural analysis software was used to optimize the structure as a whole. By controlling the stress ratio, maximum deformation, vertical and lateral support device reaction force of the stressed member during the operation stage and the climbing stage, the bearing capacity requirements were met. The results show that the temporary steel structure support system solves the load transfer problem of large?scale mechanical equipment by locally adopting high?capacity cylinder support structure and high?capacity steel beam climbing structure in the integrated part, and the temporary steel structure is driven by large?tonnage hydraulic cylinders, which realized automatic climbing by the alternate support of support structure and climbing structure.

Keywords:super high?rise building; integral formwork; high bearing capacity; large construction machinery; integration
