樓(lou)承板(ban)(ban)(ban)鋼(gang)結構(gou)柱網間距一般(ban)5~9.0m×8~15m，次(ci)梁(liang)間距3m，而樓(lou)承板(ban)(ban)(ban)下料長度(du)為4.97~8.97m，運(yun)輸(shu)與安裝均(jun)較困(kun)難(nan)(nan)，尤其(qi)是帶(dai)由(you)圓弧區(qu)垂(chui)直(zhi)吊(diao)(diao)裝樓(lou)承板(ban)(ban)(ban)，由(you)上(shang)(shang)而下在(zai)次(ci)梁(liang)狹(xia)間穿套比較困(kun)難(nan)(nan)，且打亂了次(ci)梁(liang)焊(han)(han)(han)接正常(chang)工序。控制下料長度(du)為3～6m，則可避(bi)免(mian)垂(chui)直(zhi)運(yun)輸(shu)時(shi)(shi)(shi)在(zai)次(ci)梁(liang)間無法吊(diao)(diao)運(yun)的問題(ti)。 樓(lou)承板(ban)(ban)(ban)吊(diao)(diao)運(yun)時(shi)(shi)(shi)采用(yong)(yong)專用(yong)(yong)軟吊(diao)(diao)索。每次(ci)吊(diao)(diao)裝時(shi)(shi)(shi)應檢(jian)查(cha)軟吊(diao)(diao)索是否有(you)撕裂(lie)、割(ge)斷現象。樓(lou)承板(ban)(ban)(ban)擱置在(zai)鋼(gang)梁(liang)上(shang)(shang)時(shi)(shi)(shi)應防止探頭。鋪料時(shi)(shi)(shi)操作人員應系(xi)帶(dai)，并保證(zheng)邊鋪設(she)邊固定(ding)在(zai)周邊繩上(shang)(shang)。 焊(han)(han)(han)接采用(yong)(yong)熔透點焊(han)(han)(han)連接，施焊(han)(han)(han)前應準備(bei)邊角料引弧試焊(han)(han)(han)，調整施焊(han)(han)(han)電流.因樓(lou)承板(ban)(ban)(ban)底部(bu)無水平模(mo)板(ban)(ban)(ban)及垂(chui)直(zhi)支撐，澆筑混凝土時(shi)(shi)(shi)布料不宜太集中，采用(yong)(yong)平板(ban)(ban)(ban)振搗(dao)器及時(shi)(shi)(shi)分攤(tan)振搗(dao)。

攀鋼白鐵廠家樓承板能夠滿足快速施工的需求，可以在短時間內搭建起牢固的作業平臺，而且還能把多個樓承板層鋪設壓型鋼板，分層澆筑混凝土板的流水施工作業。可以作為混凝土樓板的受拉鋼筋，可以使樓板的剛度增強，而且使得鋼筋和混凝土的用量明顯減少。白鐵廠家壓型板表面(mian)壓紋使(shi)樓(lou)承(cheng)板與混凝土之(zhi)間(jian)產生大的(de)結(jie)合力，使(shi)二者(zhe)形成整體，再配合上加(jia)勁肋(lei)，使(shi)得有高強承(cheng)載力。還可以作(zuo)為性模板，懸挑的(de)長度可根據(ju)樓(lou)承(cheng)板的(de)截面(mian)特(te)性來(lai)定(ding)(ding)。為了防(fang)止懸挑板的(de)開裂(lie)，需在支(zhi)座處(chu)依結(jie)構工程師的(de)設計配上負筋。而且都是經過固定(ding)(ding)滅火(huo)(huo)系統(tong)及耐火(huo)(huo)構件質量檢(jian)測中心的(de)耐火(huo)(huo)檢(jian)測，具有防(fang)火(huo)(huo)的(de)特(te)性。
