上海浦东图书馆(新馆)工程中清水混凝土圆柱施工采用了纸筒模板这一新型的模板体系,取得了良好的效果。纸筒模板采用多层特殊耐水复合纸卷制而成,直径、高度均可定制加工,无需现场拼接;纸筒模板自重轻,对吊装机械要求低;纸筒自身刚度可满足混凝土浇筑过程中产生的侧压力,柱高上、中、下设了3道定位箍以调节模板垂直度,安装、拆模施工便捷。在类似工程中,纸筒模板比常规模板在环保节能、质量控制、施工管理、经济效益等方面均占优势。
Shanghai Pudong Library (New Hall) project in the construction of clear water concrete cylinder paper used a new template system, and achieved good results. Paper template with multi-layer special water-resistant composite paper roll made of diameter and height can be customized processing, without on-site splicing; paperboard template light weight, low hoisting machinery requirements; paper cylinder stiffness to meet the concrete pouring process generated Of the side pressure, column height, in the next set of three positioning hoop to adjust the template verticality, installation, demolition mold construction convenient. In similar projects, the paperboard template than the conventional template in environmental protection and energy saving, quality control, construction management, economic benefits and other advantages.
