自貢鍍鋅管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。 鍍鋅管批發樓承板吊(diao)運時采(cai)用專用軟(ruan)吊(diao)索(suo)。每(mei)次吊(diao)裝時應檢查軟(ruan)吊(diao)索(suo)是否有(you)撕(si)裂(lie)、割斷(duan)現象。樓承板擱置在鋼梁上時應防止探頭。鋪(pu)料(liao)時操作人員(yuan)應系帶(dai)，并保證邊(bian)(bian)(bian)(bian)鋪(pu)設邊(bian)(bian)(bian)(bian)固定在周邊(bian)(bian)(bian)(bian)繩(sheng)上。 焊接采(cai)用熔透點(dian)焊連接，施焊前應準備邊(bian)(bian)(bian)(bian)角料(liao)引(yin)弧試焊，調整施焊電流(liu).因(yin)樓承板底部無水平模板及垂直(zhi)支撐，澆筑混(hun)凝土(tu)時布(bu)料(liao)不宜太集中(zhong)，采(cai)用平板振(zhen)搗器及時分攤振(zhen)搗。
