保山C型鋼樓承板鋼結構柱網間距一般5~9.0m×8~15m，次梁間距3m，而樓承板下料長度為4.97~8.97m，運輸與安裝均較困難，尤其是帶由圓弧區垂直吊裝樓承板，由上而下在次梁狹間穿套比較困難，且打亂了次梁焊接正常工序。控制下料長度為3～6m，則可避免垂直運輸時在次梁間無法吊運的問題。 C型鋼批發樓(lou)承(cheng)(cheng)板(ban)(ban)吊運時采(cai)(cai)用(yong)專用(yong)軟(ruan)吊索。每次(ci)吊裝時應(ying)檢查軟(ruan)吊索是否有撕(si)裂、割斷(duan)現(xian)象。樓(lou)承(cheng)(cheng)板(ban)(ban)擱(ge)置在(zai)鋼(gang)梁上時應(ying)防(fang)止探頭(tou)。鋪(pu)料(liao)時操(cao)作(zuo)人(ren)員應(ying)系帶，并保證邊(bian)(bian)鋪(pu)設邊(bian)(bian)固定在(zai)周(zhou)邊(bian)(bian)繩上。 焊(han)接采(cai)(cai)用(yong)熔(rong)透點焊(han)連接，施焊(han)前應(ying)準備邊(bian)(bian)角料(liao)引弧試(shi)焊(han)，調整施焊(han)電流(liu).因(yin)樓(lou)承(cheng)(cheng)板(ban)(ban)底部無水平模板(ban)(ban)及(ji)垂直支撐，澆筑混凝(ning)土時布料(liao)不宜(yi)太集(ji)中，采(cai)(cai)用(yong)平板(ban)(ban)振搗器(qi)及(ji)時分攤振搗。
