河南冷軋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。 冷軋卷價格樓(lou)承板(ban)(ban)吊運時(shi)采(cai)用(yong)(yong)專用(yong)(yong)軟吊索(suo)(suo)。每次吊裝時(shi)應(ying)(ying)檢查軟吊索(suo)(suo)是否(fou)有(you)撕裂、割斷(duan)現象。樓(lou)承板(ban)(ban)擱(ge)置在鋼梁上時(shi)應(ying)(ying)防(fang)止探頭。鋪料時(shi)操作人(ren)員應(ying)(ying)系帶(dai)，并保證邊(bian)(bian)鋪設邊(bian)(bian)固定在周邊(bian)(bian)繩(sheng)上。 焊(han)(han)接采(cai)用(yong)(yong)熔透點焊(han)(han)連接，施焊(han)(han)前(qian)應(ying)(ying)準備邊(bian)(bian)角料引弧(hu)試焊(han)(han)，調整(zheng)施焊(han)(han)電流.因樓(lou)承板(ban)(ban)底部(bu)無水平(ping)(ping)模板(ban)(ban)及垂直(zhi)支(zhi)撐，澆筑混凝土時(shi)布料不(bu)宜太集中，采(cai)用(yong)(yong)平(ping)(ping)板(ban)(ban)振(zhen)(zhen)搗(dao)器及時(shi)分攤振(zhen)(zhen)搗(dao)。
