1、Hb第一節錨栓錨栓用于上部鋼結構與下部基礎的連接，承受柱彎矩在柱腳底板與基礎間產生的拉力剪力由柱底板與基礎面之間的摩擦力抵抗，若摩擦力不足以抵抗剪力，則需在柱底板上焊接抗剪鍵以增大抗剪能力。錨栓一頭埋入混凝土中，埋入的長度要以混凝土對其的握裹力不小于其自身強度為原則，所以對于不同的混凝土標號和錨栓強度，所需最小埋入長度也不一樣。為了增加握裹力，對于e39以下錨栓，需將其下端彎成L型，彎鉤的長度為4D；對于e39以上錨栓，因其直徑過大不便于折彎，則在其下端焊接錨固板。文檔收集自網絡，僅用于個人學習錨栓的錨固及構造詳見表7-5與表7-6。個人收集整理僅供參考學習個人收集整理僅供參考學習 /7表7-
