1、Hb第一節(jié)錨栓錨栓用于上部鋼結(jié)構(gòu)與下部基礎(chǔ)的連接，承受柱彎矩在柱腳底板與基礎(chǔ)間產(chǎn)生的拉力剪力由柱底板與基礎(chǔ)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(zhǎng)度要以混凝土對(duì)其的握裹力不小于其自身強(qiáng)度為原則，所以對(duì)于不同的混凝土標(biāo)號(hào)和錨栓強(qiáng)度，所需最小埋入長(zhǎng)度也不一樣。為了增加握裹力，對(duì)于e39以下錨栓，需將其下端彎成L型，彎鉤的長(zhǎng)度為4D；對(duì)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(wǎng)絡(luò)，僅用于個(gè)人學(xué)習(xí)錨栓的錨固及構(gòu)造詳見表7-5與表7-6。個(gè)人收集整理僅供參考學(xué)習(xí)個(gè)人收集整理僅供參考學(xué)習(xí) /7表7-
