在现浇钢筋混凝土施工中,模板系统的操作方法和周转速度,在很大程度上能影响建筑工程的工期和成本投入,早期拆模技术能节省模板费用,本文从以下几个方面介绍该技术的应用。一、工作原理传统的水平现浇混凝土施工方法为顶杆支撑龙骨,龙骨上安放模板,模板上浇筑混凝土(图1);现浇混凝土养护10~14d后,才能拆除全部模板和顶杆,不能更早拆除模板的原因在于新浇筑的混凝土强度太低。针对这个问题,提出了以下设想:顶杆和模板
In the cast-in-place reinforced concrete construction, the operation and speed of the formwork system can largely affect the construction time and cost, and the early formwork removal technology can save the template cost. This article introduces the technology in the following aspects Applications. First, the working principle of the traditional level of cast-in-place concrete construction method for the mandrel support keel, keel placed on the template, the template pouring concrete (Figure 1); pouring concrete conservation 10 ~ 14d, to remove all the template and the mandrel can not The earlier demolition of the template is that the strength of the newly poured concrete is too low. In response to this problem, the following ideas were proposed: ram and template
