浅析铸钢件在输电线路铁塔上的应用

Brief Analysis on the Application of Steel Castings in Transmission Line Tower

主要分析了输电铁塔的连接节点的特点,结合两个案例浅析了应用于输电铁塔的铸钢件节点的结构特点、技术要求、热处理、焊接和镀锌工艺等。解决了繁杂部位焊接量大、难度高、应力集中等工程建设问题,缩短了输电铁塔的建设周期。最后,给出了输电铁塔铸钢件节点生产制造的质量控制措施。

This article mainly analyzes the characteristics of the connection nodes of transmission towers,and analyzes the structural characteristics,technical requirements,heat treatment,welding and galvanizing processes of the cast steel joints used in the transmission tower combined with two cases.Engineering construction problems such as large welding volume were solved,high difficulty,and stress concentration in complex parts,and the construction cycle of transmission towers was shortened.Finally,the quality control measures for the production of cast steel joints of transmission tower are given.
