該沈陽(yang)鋼(gang)結(jie)構工程(cheng)鋼(gang)梁、柱(zhu)(zhu)連(lian)(lian)接采用(yong)(yong)大(da)六角高(gao)(gao)強(qiang)(qiang)螺(luo)栓(shuan)，安(an)裝(zhuang)(zhuang)高(gao)(gao)強(qiang)(qiang)螺(luo)栓(shuan)時構件(jian)的(de)磨擦面應保護干燥清(qing)潔，不(bu)(bu)得(de)在雨(yu)中(zhong)作(zuo)業。擰緊(jin)(jin)順序應從(cong)節(jie)點(dian)(dian)板(ban)中(zhong)心(xin)向(xiang)邊緣施擰，兩個(ge)連(lian)(lian)接件(jian)的(de)順序為(wei)(wei)先主要后(hou)次要，H型(xing)鋼(gang)構件(jian)為(wei)(wei)上(shang)翼緣、下(xia)(xia)翼緣、復板(ban)的(de)順序，同(tong)(tong)一節(jie)柱(zhu)(zhu)上(shang)梁、柱(zhu)(zhu)節(jie)點(dian)(dian)緊(jin)(jin)擰順序為(wei)(wei)先上(shang)梁柱(zhu)(zhu)接點(dian)(dian)再下(xia)(xia)梁柱(zhu)(zhu)節(jie)點(dian)(dian)，最后(hou)為(wei)(wei)中(zhong)間(jian)梁柱(zhu)(zhu)節(jie)點(dian)(dian)。高(gao)(gao)強(qiang)(qiang)螺(luo)栓(shuan)緊(jin)(jin)固程(cheng)度用(yong)(yong)扭矩(ju)扳手(shou)進行控制，其外露絲扣為(wei)(wei)2-3絲，連(lian)(lian)接檁條墻梁用(yong)(yong)的(de)普(pu)通螺(luo)栓(shuan)每個(ge)螺(luo)栓(shuan)墊(dian)兩個(ge)墊(dian)圈(quan)。所(suo)有(you)安(an)裝(zhuang)(zhuang)螺(luo)孔(kong)(kong)，均不(bu)(bu)得(de)采用(yong)(yong)氣割擴孔(kong)(kong)，當板(ban)疊(die)銷孔(kong)(kong)超出(chu)允許偏差造成連(lian)(lian)接螺(luo)栓(shuan)不(bu)(bu)能穿通時，可用(yong)(yong)鉸刀進行修整，但(dan)修整后(hou)的(de)最大(da)直徑(jing)應小于螺(luo)栓(shuan)直徑(jing)的(de)1.2倍，鉸孔(kong)(kong)時應防止鐵(tie)屑落入板(ban)疊(die)縫(feng)隙。同(tong)(tong)時本工程(cheng)所(suo)有(you)規格的(de)高(gao)(gao)強(qiang)(qiang)螺(luo)栓(shuan)經監理見證取樣(yang)后(hou)送試驗室(shi)試驗。

該工程(cheng)安(an)(an)裝(zhuang)(zhuang)擬編制一個班組6人(ren)專門負(fu)責(ze)高(gao)強度螺(luo)(luo)栓(shuan)施工，其中(zhong)螺(luo)(luo)栓(shuan)安(an)(an)裝(zhuang)(zhuang)4人(ren)，初擰(ning)2人(ren)，終擰(ning)2人(ren)，必(bi)須做到當(dang)天(tian)安(an)(an)裝(zhuang)(zhuang)的螺(luo)(luo)栓(shuan)當(dang)天(tian)終擰(ning)完畢。
