［摘要］以杭州蕭山國際機場三期新建T4航站樓鋼結(jié)構(gòu)屋蓋制造為例，深入剖析了屋蓋分叉節(jié)點、桁架弦桿節(jié)點、屋面焊接空心球網(wǎng)架等鋼結(jié)構(gòu)制造特點與難點，并對鋼結(jié)構(gòu)屋蓋制造的關(guān)鍵技術(shù)進行了詳細說明。通過這些關(guān)鍵技術(shù)的應(yīng)用，保證了本工程鋼結(jié)構(gòu)屋蓋制造的順利進行，這些技術(shù)對其他類似鋼結(jié)構(gòu)工程具有一定參考價值。
［關(guān)鍵詞］杭州蕭山國際機場；鋼結(jié)構(gòu)屋蓋；分叉節(jié)點；封邊桁架；焊接空心球；拼裝
