蘭州樓承板，也(ye)叫(jiao)壓(ya)(ya)型(xing)(xing)(xing)鋼(gang)板(ban)(ban)(ban)、鋼(gang)承(cheng)板(ban)(ban)(ban)、鋼(gang)樓承(cheng)板(ban)(ban)(ban)。最早(zao)叫(jiao)壓(ya)(ya)型(xing)(xing)(xing)鋼(gang)板(ban)(ban)(ban)，即所有經壓(ya)(ya)板(ban)(ban)(ban)機壓(ya)(ya)制成(cheng)(cheng)型(xing)(xing)(xing)的(de)(de)鋼(gang)板(ban)(ban)(ban)的(de)(de)統稱。樓承(cheng)板(ban)(ban)(ban)是(shi)采用(yong)(yong)鍍鋅鋼(gang)板(ban)(ban)(ban)經輥壓(ya)(ya)冷彎成(cheng)(cheng)型(xing)(xing)(xing)，其截面(mian)(mian)成(cheng)(cheng)V型(xing)(xing)(xing)、U型(xing)(xing)(xing)、梯(ti)形(xing)或類(lei)似這(zhe)幾種形(xing)狀的(de)(de)波形(xing)，主要用(yong)(yong)作永久性模板(ban)(ban)(ban)，也(ye)可(ke)被選為其他用(yong)(yong)途。最早(zao)的(de)(de)壓(ya)(ya)型(xing)(xing)(xing)鋼(gang)板(ban)(ban)(ban)主要是(shi)用(yong)(yong)于廠(chang)房屋面(mian)(mian)的(de)(de)屋面(mian)(mian)板(ban)(ban)(ban)，后(hou)面(mian)(mian)有用(yong)(yong)于樓層(ceng)的(de)(de)壓(ya)(ya)型(xing)(xing)(xing)鋼(gang)板(ban)(ban)(ban)后(hou)逐漸(jian)分類(lei)稱為樓承(cheng)板(ban)(ban)(ban)。  

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)型材厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高5 1 mm ~76mm.工程樓(lou)(lou)面樓(lou)(lou)承(cheng)板(ban)(ban)(ban)與(yu)鋼筋混凝土結構(gou)共同作用，系復合(he)結構(gou)。樓(lou)(lou)承(cheng)板(ban)(ban)(ban)鋪設與(yu)鋼梁(liang)(liang)連接(jie)，板(ban)(ban)(ban)端頭(tou)(tou)與(yu)鋼梁(liang)(liang)熔(rong)(rong)透(tou)點(dian)(dian)焊(han)，中間(jian)采用栓釘與(yu)鋼梁(liang)(liang)穿透(tou)熔(rong)(rong)焊(han)；樓(lou)(lou)承(cheng)板(ban)(ban)(ban)間(jian)用專用夾緊鉗咬合(he)壓孔連接(jie)；堵(du)頭(tou)(tou)用專用鍍鋅堵(du)頭(tou)(tou)板(ban)(ban)(ban)與(yu)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)及鋼梁(liang)(liang)點(dian)(dian)焊(han)。如果是帶弧形區樓(lou)(lou)承(cheng)板(ban)(ban)(ban)異型裁切采用等離(li)子切割機切割，其(qi)切口光(guang)滑，表面鍍鋅層完整(zheng)。樓(lou)(lou)承(cheng)板(ban)(ban)(ban)焊(han)接(jie)采用手工電弧點(dian)(dian)焊(han)，焊(han)條為Ｅ4303，直徑3.2mm，熔(rong)(rong)透(tou)焊(han)接(jie)點(dian)(dian)為16mm.原設計焊(han)點(dian)(dian)間(jian)距305mm，后將焊(han)點(dian)(dian)增(zeng)加(jia)1倍，以(yi)確保操作人員行走時(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)不變形，混凝土澆(jiao)筑時(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)端頭(tou)(tou)不漏漿(jiang)。當樓(lou)(lou)面層結構(gou)標(biao)高變化不一致(zhi)時(shi)，采取加(jia)焊(han)型鋼措(cuo)施，使水平結構(gou)呈臺階(jie)過渡，當降(jiang)低標(biao)高時(shi)工字梁(liang)(liang)腹板(ban)(ban)(ban)加(jia)焊(han)角鋼；抬升標(biao)高時(shi)工字梁(liang)(liang)翼緣(yuan)加(jia)焊(han)槽鋼。  

樓(lou)承板的特(te)點(dian) 

1：適應主體鋼結構快速施工的(de)要(yao)求，能夠在短時間(jian)內提供堅定的(de)作業平臺，并可(ke)采用多個(ge)樓層鋪設壓(ya)型鋼板(ban)，分層澆筑混凝土板(ban)的(de)流水施工。 

2：在使用階段樓承板(ban)作為混凝(ning)土(tu)樓板(ban)的受拉鋼筋，也提高(gao)了樓板(ban)的剛度，節省了鋼筋和混凝(ning)土(tu)的用量。 

3：壓型板(ban)表面壓紋使(shi)樓(lou)承(cheng)板(ban)與混凝土之間產生(sheng)最大的結合(he)力，使(shi)二者形成整體(ti)，配以(yi)加勁肋，使(shi)樓(lou)承(cheng)板(ban)系統具(ju)有高(gao)強承(cheng)載力。 

4：在懸(xuan)臂條件下，樓承(cheng)板(ban)僅作為永久性模板(ban)。懸(xuan)挑(tiao)的長(chang)度可根據樓承(cheng)板(ban)的截面特性來定。為了防止懸(xuan)挑(tiao)板(ban)的開裂，需在支座處(chu)依結構工程師(shi)的設(she)計配上負筋。 

5：本公司樓承(cheng)板(ban)已通(tong)過國家固定滅火(huo)系統(tong)及耐火(huo)構件質量檢測中(zhong)心的耐火(huo)極限(xian)檢測，作為組合樓承(cheng)板(ban)無需防火(huo)噴涂(tu)，因(yin)此大大降低了工程造價。
