實現了機械(xie)化(hua)生(sheng)(sheng)產，有利于鋼(gang)筋排列間(jian)距均勻、混(hun)凝土(tu)保(bao)護層厚(hou)度一致，提高了樓板(ban)的施(shi)工(gong)(gong)(gong)質(zhi)量(liang)。裝配(pei)式鋼(gang)筋桁架(jia)樓承(cheng)板(ban)可(ke)顯著減少現場鋼(gang)筋綁扎工(gong)(gong)(gong)程量(liang)，加(jia)快施(shi)工(gong)(gong)(gong)進度，增加(jia)施(shi)工(gong)(gong)(gong)保(bao)證(zheng)，實現文明施(shi)工(gong)(gong)(gong)。裝配(pei)式模(mo)板(ban)和連接(jie)件拆(chai)裝方(fang)便，可(ke)多次(ci)重復(fu)利用(yong)，節約鋼(gang)材，符合國家節能(neng)環保(bao)的要求(qiu)。鋼(gang)構自(zi)(zi)主研發的產品(pin)配(pei)套自(zi)(zi)動化(hua)生(sheng)(sheng)產設備，大大提高了勞動生(sheng)(sheng)產率，有效降低(di)了產品(pin)成本，并(bing)編制了產品(pin)生(sheng)(sheng)產企業(ye)標準、設計手(shou)(shou)冊(ce)和節點構造圖集(ji)以(yi)及施(shi)工(gong)(gong)(gong)手(shou)(shou)冊(ce)。并(bing)經過多項工(gong)(gong)(gong)程應(ying)用(yong)，各項性能(neng)可(ke)以(yi)滿足現澆鋼(gang)筋混(hun)凝土(tu)樓板(ban)承(cheng)載力(li)和變(bian)形的要求(qiu)。

樓(lou)承板鋼(gang)結構柱網(wang)間距(ju)一般5~9.0m×8~15m，次(ci)梁(liang)(liang)間距(ju)3m，而樓(lou)承板下料(liao)長度為4.97~8.97m，運輸與安裝均較困(kun)難，尤其是(shi)帶由(you)圓弧區垂(chui)直(zhi)吊(diao)(diao)裝樓(lou)承板，由(you)上而下在(zai)次(ci)梁(liang)(liang)狹(xia)間穿套比(bi)較困(kun)難，且打亂(luan)了次(ci)梁(liang)(liang)焊(han)接(jie)正常工序。控制下料(liao)長度為3～6m，則可避免垂(chui)直(zhi)運輸時(shi)(shi)在(zai)次(ci)梁(liang)(liang)間無法吊(diao)(diao)運的問題。 樓(lou)承板吊(diao)(diao)運時(shi)(shi)采(cai)用專用軟吊(diao)(diao)索(suo)。每次(ci)吊(diao)(diao)裝時(shi)(shi)應(ying)檢查軟吊(diao)(diao)索(suo)是(shi)否有撕裂(lie)、割斷現象。樓(lou)承板擱(ge)置(zhi)在(zai)鋼(gang)梁(liang)(liang)上時(shi)(shi)應(ying)防止探(tan)頭。鋪料(liao)時(shi)(shi)操(cao)作人員(yuan)應(ying)系帶，并保證邊鋪設邊固定在(zai)周(zhou)邊繩(sheng)上。 焊(han)接(jie)采(cai)用熔透點焊(han)連接(jie)，施焊(han)前應(ying)準備邊角料(liao)引弧試焊(han)，調整施焊(han)電流(liu).因樓(lou)承板底部無水平(ping)模板及垂(chui)直(zhi)支(zhi)撐，澆筑(zhu)混(hun)凝土時(shi)(shi)布料(liao)不宜太集中，采(cai)用平(ping)板振搗器及時(shi)(shi)分攤振搗。

云南酒鋼鍍鋅鋼板樓承板鍍鋅首要起到防腐的效果，按標準組合樓板與非組合樓板壓型鋼板應選用熱鍍鋅，不該選用電鍍鋅鋼板，其雙面鍍鋅層總含量要滿足在使用期間不致銹損的要求。當作為非組合樓承板時，鍍鋅層含量可選用較低值;當為組合樓承板時，鍍鋅層含量不該小于150g/m2。當為組合樓板且使用環境條件較為惡劣時，鍍鋅層含量應選用上限值或更高值。更高的鍍鋅要求，如雙面鍍鋅量為300g/m2、350g/m2或鍍鋁鋅(5%鋁)275g/m2、300g/m2等，較高的鍍層量使組合樓板有更長耐久性，同等量的鍍鋁鋅的防銹蝕才能大約兩倍于一般熱鍍鋅。鍍鋅鋼板批發鍍鋅量(liang)也不(bu)是(shi)越厚越好(hao)，當(dang)鍍鋅量(liang)較厚時，抗剪(jian)連接(jie)(jie)件栓(shuan)釘的(de)焊接(jie)(jie)質量(liang)就很(hen)難(nan)保證，焊接(jie)(jie)時，宜選用局部除鋅處理措施。
