模板是用来保证混凝土和钢筋混凝土构件各部分形状、尺寸和相互位置的,必须具有足够的强度、刚度和稳定性,以便能可靠地承受新灌筑混凝土的重量和侧压力,以及在施工过程中所产生的荷载。所以,模板工程对于保证结构工程质量是至关重要的。同时,模板工程需用的材料和投资亦是十分可观的。就建设火电厂来说,2×12.5万千瓦机组需用木材约一万立方米,2×30万千瓦机组约需二万立方米。目前全国正在推广采用钢模代替木模,宝钢自备电厂2×35万千瓦机组基本上使用钢
The formwork is designed to assure the shape, size and mutual position of the various components of concrete and reinforced concrete members and must be of sufficient strength, rigidity and stability to reliably withstand the weight and lateral pressure of freshly laid concrete and to be used during construction In the load generated. Therefore, formwork engineering is crucial to ensure the quality of structural engineering. At the same time, the materials and investment required for the formwork project are also considerable. For the construction of coal-fired power plants, 2 × 125 MW units require about 10,000 m3 of timber and 2 × 300,000 kW units require about 20,000 m3. At present, the country is promoting the use of steel instead of wood, Baosteel own power plant 2 × 350 MW unit basically use steel
