不可展锥曲线面构筑物树脂衬钢模板制作技术

Manufacture Technology of Non-developable Conic Surface Structures of Resin Lining Steel Formwork

通过嘉峪关市南市区至新火车站道路工程(二标段)讨赖河大桥主桥墩模板的加工制作施工,阐述了一种利用钢模板和环氧树脂的特点,采取以直代曲、近似展开下料、条块简易拼装的方法,将钢骨架焊接成相似于各种异型形状,以环氧树脂作为内衬,获得既有强度和刚度,又符合构筑物设计表面形状的大型钢骨架树脂衬钢模板的加工技术。

According to the processing manufacture construction of the main bridge pier template of Taolai River Bridge in Jiayuguan City Nanshi District-New Railway Station Project(Bid II), this article sets forth a method of utilizing the characteristics of steel formwork and epoxy resin, and replacing curve by straight line,approximate expansion blanking, and slice simple assembly to weld the steel skeleton into various similarly different shapes, which can achieve the existing strength and stiffness with epoxy resin as lining, and also conform to the processing technology of large steel skeleton resin lining steel formwork in the design surface shape of structure.
