樓(lou)承板(ban)(ban)鋼(gang)結構柱網(wang)間距一般5~9.0m×8~15m，次(ci)(ci)梁(liang)間距3m，而(er)樓(lou)承板(ban)(ban)下(xia)料(liao)長度為4.97~8.97m，運輸(shu)與安(an)裝均較困難，尤其是帶由(you)圓弧(hu)區垂直(zhi)吊裝樓(lou)承板(ban)(ban)，由(you)上(shang)而(er)下(xia)在(zai)次(ci)(ci)梁(liang)狹間穿套比(bi)較困難，且打亂(luan)了(le)次(ci)(ci)梁(liang)焊接正常工序。控(kong)制下(xia)料(liao)長度為3～6m，則(ze)可避免垂直(zhi)運輸(shu)時(shi)(shi)在(zai)次(ci)(ci)梁(liang)間無法吊運的(de)問題。 樓(lou)承板(ban)(ban)吊運時(shi)(shi)采(cai)用專用軟(ruan)吊索。每次(ci)(ci)吊裝時(shi)(shi)應檢查軟(ruan)吊索是否有撕(si)裂(lie)、割斷(duan)現象。樓(lou)承板(ban)(ban)擱置在(zai)鋼(gang)梁(liang)上(shang)時(shi)(shi)應防止探頭。鋪(pu)料(liao)時(shi)(shi)操作(zuo)人員應系帶，并保證(zheng)邊(bian)鋪(pu)設(she)邊(bian)固定在(zai)周邊(bian)繩上(shang)。 焊接采(cai)用熔透點焊連接，施焊前(qian)應準備(bei)邊(bian)角料(liao)引弧(hu)試焊，調整施焊電流(liu).因樓(lou)承板(ban)(ban)底部無水平(ping)模(mo)板(ban)(ban)及(ji)垂直(zhi)支撐，澆筑混凝土時(shi)(shi)布料(liao)不宜太集中，采(cai)用平(ping)板(ban)(ban)振搗器及(ji)時(shi)(shi)分攤振搗。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。昆明彩涂板規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。彩涂板批發而縮口(kou)(kou)(kou)板(ban)(ban)和閉口(kou)(kou)(kou)板(ban)(ban)，只(zhi)需要(yao)總的樓(lou)板(ban)(ban)厚度大于等于110即可，但(dan)是縮口(kou)(kou)(kou)板(ban)(ban)雖(sui)然(ran)在防火方面比開口(kou)(kou)(kou)板(ban)(ban)要(yao)好(hao)。但(dan)是底部還是需要(yao)加板(ban)(ban)底受力筋(jin)，而閉口(kou)(kou)(kou)板(ban)(ban)則不需要(yao)。
