拴焊结构钢管铁塔系近年来国内开发设计的一种新产品,用于沿海地区的大跨越高塔(塔高100～200余米)。铁塔全部采用φ300～650的薄壁钢管,段位和水平隔面均用法兰连接,每基塔有主管100多根,横管100多根,法兰盘400多个且每个装配单元均受空间位置约束,相互都有位置度要求,标准段的装配均要求互换,因此加工工艺难度大、要求高。 Shuan welded steel pipe structure in recent years, the domestic development and design of a new product for the coastal areas across the tower (100 to 200 meters high tower). All the tower uses φ300 ~ 650 thin-walled steel pipe, section and level of the two sides are flanged connection, each tower has more than 100 competent, horizontal pipe more than 100, more than 400 flanges and each assembly unit are subject to space Position constraints, each position has the degree of requirements, the standard section of the assembly are required to exchange, so the processing technology is difficult, demanding.
