一、前言在火力发电厂土建施工中,目前各单位已广泛使用了定型组合钢模板,其使用面积达到85％以上,并都收到了较好的经济效果。但是,对外形较复杂的构件,如厂房的钢筋混凝土牛腿,混凝土冷风道及循环水沟的八字角仍需大量木材。由于构件造型复杂,木模容易变形,钢木同时施工连接不牢,给施工带来一定困难。为此,提出设计部分异型钢模板,使之与定型钢模板一起使用,不仅能使模板不容易变形,提高了工程质量,而且简化了支撑系统,提高
I. INTRODUCTION In the civil construction of thermal power plants, various types of steel structures have been widely used by various units. Their use area has reached over 85%, and they have received good economic results. However, for the more complex components, such as the reinforced concrete legs of the factory, the cold air channels of the concrete and the circular grooves of the concrete, a large amount of wood is still required. Due to the complex shape of the components, the wood mold is easily deformed, and the steel and wood are not connected firmly at the same time, which brings certain difficulties to the construction. For this reason, designing a part of special-shaped steel formwork to be used together with the shaped steel formwork not only can make the formwork not easily deformed, improves the project quality, but also simplifies the support system and improves
