宜賓鍍鋅卷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。 鍍鋅卷批發樓(lou)承板(ban)吊(diao)(diao)運時(shi)采(cai)用專用軟吊(diao)(diao)索。每(mei)次吊(diao)(diao)裝時(shi)應(ying)檢(jian)查軟吊(diao)(diao)索是否有撕裂、割斷現象。樓(lou)承板(ban)擱置在(zai)鋼梁上(shang)時(shi)應(ying)防止探頭。鋪(pu)料(liao)時(shi)操(cao)作人員應(ying)系帶，并保證邊(bian)(bian)鋪(pu)設邊(bian)(bian)固定(ding)在(zai)周(zhou)邊(bian)(bian)繩上(shang)。 焊(han)接采(cai)用熔(rong)透(tou)點焊(han)連接，施焊(han)前應(ying)準(zhun)備(bei)邊(bian)(bian)角料(liao)引弧試焊(han)，調整(zheng)施焊(han)電流.因樓(lou)承板(ban)底部無水平(ping)模板(ban)及垂直支(zhi)撐，澆筑混(hun)凝土時(shi)布料(liao)不(bu)宜(yi)太(tai)集中，采(cai)用平(ping)板(ban)振搗(dao)器及時(shi)分攤振搗(dao)。
