蘭州樓承板，也叫壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)、鋼(gang)(gang)(gang)(gang)承(cheng)板(ban)(ban)(ban)(ban)、鋼(gang)(gang)(gang)(gang)樓(lou)承(cheng)板(ban)(ban)(ban)(ban)。最早(zao)叫壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，即(ji)所有經壓(ya)(ya)板(ban)(ban)(ban)(ban)機壓(ya)(ya)制成型(xing)的(de)(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)(de)統(tong)稱(cheng)。樓(lou)承(cheng)板(ban)(ban)(ban)(ban)是(shi)采用(yong)鍍鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)經輥壓(ya)(ya)冷彎成型(xing)，其截(jie)面(mian)成V型(xing)、U型(xing)、梯形或類(lei)似這幾種形狀的(de)(de)(de)波形，主(zhu)要用(yong)作永久性模板(ban)(ban)(ban)(ban)，也可被選為(wei)其他用(yong)途。最早(zao)的(de)(de)(de)壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)主(zhu)要是(shi)用(yong)于廠房屋面(mian)的(de)(de)(de)屋面(mian)板(ban)(ban)(ban)(ban)，后面(mian)有用(yong)于樓(lou)層(ceng)的(de)(de)(de)壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)后逐漸分類(lei)稱(cheng)為(wei)樓(lou)承(cheng)板(ban)(ban)(ban)(ban)。  

樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)型(xing)材(cai)厚(hou)0.8mm、1.0mm、1.2mm寬688mm~940mm，高(gao)5 1 mm ~76mm.工程樓(lou)(lou)(lou)(lou)(lou)(lou)面(mian)樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)與(yu)鋼(gang)(gang)筋(jin)混(hun)凝土結構共同作用(yong)，系復合(he)結構。樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)鋪設與(yu)鋼(gang)(gang)梁(liang)(liang)(liang)連(lian)接(jie)，板(ban)(ban)端頭(tou)與(yu)鋼(gang)(gang)梁(liang)(liang)(liang)熔透(tou)(tou)點焊，中間采用(yong)栓(shuan)釘與(yu)鋼(gang)(gang)梁(liang)(liang)(liang)穿透(tou)(tou)熔焊；樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)間用(yong)專用(yong)夾緊鉗咬合(he)壓孔(kong)連(lian)接(jie)；堵頭(tou)用(yong)專用(yong)鍍鋅堵頭(tou)板(ban)(ban)與(yu)樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)及鋼(gang)(gang)梁(liang)(liang)(liang)點焊。如(ru)果(guo)是帶弧(hu)形區樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)異型(xing)裁(cai)切采用(yong)等離子切割機切割，其切口光滑，表面(mian)鍍鋅層完整。樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)焊接(jie)采用(yong)手工電弧(hu)點焊，焊條為(wei)Ｅ4303，直徑3.2mm，熔透(tou)(tou)焊接(jie)點為(wei)16mm.原設計焊點間距305mm，后將焊點增加(jia)1倍，以(yi)確保操(cao)作人員行(xing)走時(shi)(shi)樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)不(bu)(bu)變(bian)形，混(hun)凝土澆(jiao)筑時(shi)(shi)樓(lou)(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)端頭(tou)不(bu)(bu)漏漿。當樓(lou)(lou)(lou)(lou)(lou)(lou)面(mian)層結構標高(gao)變(bian)化不(bu)(bu)一致時(shi)(shi)，采取加(jia)焊型(xing)鋼(gang)(gang)措施，使(shi)水(shui)平結構呈臺(tai)階過渡，當降低(di)標高(gao)時(shi)(shi)工字梁(liang)(liang)(liang)腹板(ban)(ban)加(jia)焊角鋼(gang)(gang)；抬升標高(gao)時(shi)(shi)工字梁(liang)(liang)(liang)翼(yi)緣加(jia)焊槽鋼(gang)(gang)。  

樓承板的(de)特點 

1：適應主體鋼結構快速施工的(de)要(yao)求，能夠在(zai)短時(shi)間內提供堅定的(de)作業平(ping)臺，并可采用多個樓層鋪設壓(ya)型鋼板，分層澆筑混凝(ning)土板的(de)流水(shui)施工。 

2：在使用階段樓(lou)承板(ban)作(zuo)為混凝土樓(lou)板(ban)的(de)(de)受拉鋼筋，也提(ti)高(gao)了(le)樓(lou)板(ban)的(de)(de)剛度(du)，節省了(le)鋼筋和混凝土的(de)(de)用量。 

3：壓(ya)型板(ban)表面壓(ya)紋使(shi)樓承板(ban)與混(hun)凝土之間(jian)產生最大的結(jie)合力(li)，使(shi)二者(zhe)形成整體，配以加勁肋，使(shi)樓承板(ban)系統具(ju)有高強(qiang)承載力(li)。 

4：在懸臂條件下，樓(lou)承(cheng)板僅作(zuo)為(wei)永(yong)久性模板。懸挑的(de)(de)長度可(ke)根據樓(lou)承(cheng)板的(de)(de)截面特(te)性來定。為(wei)了防(fang)止懸挑板的(de)(de)開裂，需在支(zhi)座處依結構工程師的(de)(de)設計配上負筋。 

5：本(ben)公(gong)司(si)樓承板(ban)已通(tong)過(guo)國(guo)家(jia)固定(ding)滅火(huo)(huo)(huo)系統及耐火(huo)(huo)(huo)構件質量檢測(ce)中心的耐火(huo)(huo)(huo)極(ji)限檢測(ce)，作為(wei)組合(he)樓承板(ban)無需防火(huo)(huo)(huo)噴涂(tu)，因此大大降低了(le)工程造價。
