自貢鍍鋅帶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。 鍍鋅帶鋼價格樓(lou)承(cheng)板(ban)吊(diao)(diao)運時(shi)(shi)采(cai)用(yong)專用(yong)軟(ruan)吊(diao)(diao)索。每次吊(diao)(diao)裝時(shi)(shi)應檢查軟(ruan)吊(diao)(diao)索是(shi)否(fou)有(you)撕裂、割斷現(xian)象。樓(lou)承(cheng)板(ban)擱置在(zai)鋼(gang)梁(liang)上時(shi)(shi)應防止探(tan)頭。鋪(pu)料(liao)時(shi)(shi)操作人員應系帶(dai)，并保證(zheng)邊鋪(pu)設邊固定在(zai)周(zhou)邊繩(sheng)上。 焊(han)接(jie)采(cai)用(yong)熔(rong)透點焊(han)連接(jie)，施焊(han)前應準備邊角料(liao)引弧(hu)試(shi)焊(han)，調整施焊(han)電流.因樓(lou)承(cheng)板(ban)底部無水平模板(ban)及垂(chui)直支撐，澆筑混凝(ning)土(tu)時(shi)(shi)布料(liao)不(bu)宜(yi)太集中，采(cai)用(yong)平板(ban)振(zhen)搗器(qi)及時(shi)(shi)分攤振(zhen)搗。
