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)(lou)承(cheng)板吊運時(shi)采用(yong)專用(yong)軟吊索(suo)。每(mei)次吊裝時(shi)應(ying)檢查軟吊索(suo)是(shi)否有撕裂、割斷現象。樓(lou)(lou)承(cheng)板擱置在鋼梁上時(shi)應(ying)防止(zhi)探頭。鋪料時(shi)操作人員應(ying)系帶，并保證(zheng)邊鋪設邊固定在周邊繩(sheng)上。 焊接采用(yong)熔透點焊連(lian)接，施焊前應(ying)準備(bei)邊角料引弧試焊，調(diao)整(zheng)施焊電流.因樓(lou)(lou)承(cheng)板底(di)部無水平模板及垂直支撐，澆(jiao)筑混凝(ning)土時(shi)布(bu)料不宜太(tai)集中，采用(yong)平板振搗(dao)器及時(shi)分攤(tan)振搗(dao)。
