首先，在鋼結(jie)構樓(lou)(lou)層板(ban)(ban)(ban)(ban)(ban)中要達到耐火(huo)1.5小(xiao)時，總的來說可以選(xuan)擇(ze)開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)、縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)、閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)三(san)大(da)類。規范上混凝(ning)土要高(gao)(gao)于(yu)(yu)(yu)開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)肋頂之上80mm，并(bing)且板(ban)(ban)(ban)(ban)(ban)底(di)(di)需(xu)配(pei)置板(ban)(ban)(ban)(ban)(ban)底(di)(di)受(shou)力筋。還(huan)(huan)有一(yi)種(zhong)就是再(zai)開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)底(di)(di)部刷(shua)防(fang)火(huo)涂(tu)料，涂(tu)料厚(hou)度大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)15,這(zhe)樣的話，只要達到構造(zao)要求高(gao)(gao)于(yu)(yu)(yu)肋頂5公分就可以了。而(er)縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)和(he)閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)，只需(xu)要總的樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)厚(hou)度大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)110即可，但是縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)雖然在防(fang)火(huo)方面比開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)要好。但是底(di)(di)部還(huan)(huan)是需(xu)要加板(ban)(ban)(ban)(ban)(ban)底(di)(di)受(shou)力筋，而(er)閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)則不(bu)需(xu)要。

鋼(gang)筋(jin)桁架樓承板(ban)完成(cheng)了機械化出產(chan)，有(you)利于鋼(gang)筋(jin)擺放距(ju)離均勻、混凝(ning)土保護層厚度(du)共同，提高了樓板(ban)的施工(gong)(gong)質量(liang)。裝(zhuang)配(pei)式鋼(gang)筋(jin)桁架樓承板(ban)可(ke)明(ming)顯(xian)削減現場鋼(gang)筋(jin)綁扎工(gong)(gong)程(cheng)量(liang)，加(jia)(jia)速施工(gong)(gong)進度(du)，添加(jia)(jia)施工(gong)(gong)確保，完成(cheng)文明(ming)施工(gong)(gong)。裝(zhuang)配(pei)式模板(ban)和連(lian)接件拆裝(zhuang)便利，可(ke)屢次重復(fu)使用，節省(sheng)鋼(gang)材，契合國家節能環保的要(yao)求。鋼(gang)構(gou)(gou)自主研制的產(chan)品(pin)配(pei)套自動(dong)化出產(chan)設備，大(da)大(da)提高了勞(lao)動(dong)出產(chan)率，有(you)用降低了產(chan)品(pin)成(cheng)本，并編(bian)制了產(chan)品(pin)出產(chan)企業(ye)規范、規劃手冊和節點構(gou)(gou)造(zao)圖集以及施工(gong)(gong)手冊。該產(chan)品(pin)經過浙(zhe)江大(da)學土木(mu)工(gong)(gong)程(cheng)測試中心(xin)檢測，并經過多項(xiang)工(gong)(gong)程(cheng)使用，各項(xiang)功能可(ke)以滿(man)意現澆鋼(gang)筋(jin)混凝(ning)土樓板(ban)承載力和變(bian)形的要(yao)求。

樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)習慣主(zhu)體(ti)鋼(gang)結構快(kuai)速施工(gong)(gong)的(de)(de)(de)要求，能(neng)夠(gou)在短時間(jian)內(nei)提(ti)供堅定(ding)的(de)(de)(de)作業渠道(dao)，并可采用多個(ge)樓層鋪(pu)設(she)壓(ya)(ya)型(xing)鋼(gang)板(ban)(ban)(ban)(ban)，分層澆筑混(hun)凝(ning)土板(ban)(ban)(ban)(ban)的(de)(de)(de)流(liu)水施工(gong)(gong)。在運用階段(duan)樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)作為(wei)(wei)(wei)混(hun)凝(ning)土樓板(ban)(ban)(ban)(ban)的(de)(de)(de)受拉鋼(gang)筋(jin)(jin)，也(ye)提(ti)高了(le)樓板(ban)(ban)(ban)(ban)的(de)(de)(de)剛度，節(jie)省了(le)鋼(gang)筋(jin)(jin)和(he)混(hun)凝(ning)土的(de)(de)(de)用量(liang)。樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)上(shang)面能(neng)夠(gou)鋪(pu)設(she)保(bao)溫，隔音，隔熱，隔振(zhen)等資料(liao)。改進(jin)樓面性(xing)能(neng)充分發揮鋼(gang)的(de)(de)(de)杰出(chu)的(de)(de)(de)抗(kang)拉強度和(he)延性(xing)及混(hun)凝(ning)土優良的(de)(de)(de)抗(kang)壓(ya)(ya)強度和(he)較大(da)的(de)(de)(de)剛度。壓(ya)(ya)型(xing)板(ban)(ban)(ban)(ban)表面壓(ya)(ya)紋使樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)與(yu)混(hun)凝(ning)土之間(jian)產生大(da)的(de)(de)(de)結合(he)力(li)，使二者形(xing)成整(zheng)體(ti)，配(pei)以(yi)加勁肋，使樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)體(ti)系(xi)具有(you)高強承(cheng)(cheng)載力(li)。在懸(xuan)臂條件(jian)下，樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)僅(jin)作為(wei)(wei)(wei)性(xing)模板(ban)(ban)(ban)(ban)。懸(xuan)挑的(de)(de)(de)長度可根據樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)截面特性(xing)來定(ding)。為(wei)(wei)(wei)了(le)避免懸(xuan)挑板(ban)(ban)(ban)(ban)的(de)(de)(de)開裂，需在支座(zuo)處依(yi)結構工(gong)(gong)程師(shi)的(de)(de)(de)規劃配(pei)上(shang)負筋(jin)(jin)。本公(gong)司(si)樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)已通(tong)過國(guo)家(jia)固(gu)定(ding)救(jiu)活(huo)體(ti)系(xi)及耐火構件(jian)質量(liang)檢(jian)測中心(xin)的(de)(de)(de)耐火檢(jian)測，作為(wei)(wei)(wei)組合(he)樓承(cheng)(cheng)板(ban)(ban)(ban)(ban)無需防(fang)火噴涂，因而大(da)大(da)降(jiang)低(di)了(le)工(gong)(gong)程造價。
