本文介绍铝合金和钢在材性方面的差别,铝合金材料在国内外塔架行业的应用,以及国内对钢塔架在海洋地区、高山地区的腐蚀状况的研究成果。分析了铝合金在通信塔方向的应用优势,指出了铝合金的材料选择、构件承载力计算和构件连接方法是设计铝合金通信塔的重点和难点。介绍了基于相关成果,设计和建设的铝合金通信塔试点工程,并对比经济性,为今后该方面的应用提供理论参考和实践经验。
This paper introduces the differences in material properties of aluminum alloys and steels, the application of aluminum alloy materials in the tower industry at home and abroad, and the domestic research results on the corrosion status of steel towers in marine and alpine regions. The application advantages of aluminum alloy in the direction of communication tower are analyzed. It is pointed out that aluminum alloy material selection, component bearing capacity calculation and component connection method are the key points and difficulties in the design of aluminum alloy communication tower. The pilot project of aluminum alloy communication tower based on related achievements, design and construction is introduced, and economy is compared to provide theoretical reference and practical experience for the application in this aspect.
