蘭州樓承板，也叫壓型(xing)(xing)(xing)鋼板、鋼承(cheng)板、鋼樓承(cheng)板。最(zui)早(zao)叫壓型(xing)(xing)(xing)鋼板，即所有經壓板機壓制成型(xing)(xing)(xing)的鋼板的統稱(cheng)。樓承(cheng)板是(shi)采用(yong)鍍鋅鋼板經輥壓冷彎成型(xing)(xing)(xing)，其截面(mian)成V型(xing)(xing)(xing)、U型(xing)(xing)(xing)、梯形或類似這(zhe)幾種形狀的波形，主(zhu)要用(yong)作(zuo)永久性模板，也可(ke)被選為其他用(yong)途。最(zui)早(zao)的壓型(xing)(xing)(xing)鋼板主(zhu)要是(shi)用(yong)于廠房(fang)屋(wu)面(mian)的屋(wu)面(mian)板，后面(mian)有用(yong)于樓層的壓型(xing)(xing)(xing)鋼板后逐漸分(fen)類稱(cheng)為樓承(cheng)板。  

樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)型材(cai)厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高5 1 mm ~76mm.工(gong)程樓(lou)面樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)與鋼(gang)(gang)筋混凝土(tu)結(jie)構(gou)共同作用(yong)(yong)(yong)，系復合(he)結(jie)構(gou)。樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)鋪設(she)(she)與鋼(gang)(gang)梁(liang)連接，板(ban)(ban)端(duan)頭(tou)與鋼(gang)(gang)梁(liang)熔透點(dian)焊(han)，中間采(cai)用(yong)(yong)(yong)栓釘與鋼(gang)(gang)梁(liang)穿(chuan)透熔焊(han)；樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)間用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)夾緊鉗咬合(he)壓孔連接；堵頭(tou)用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)鍍(du)鋅(xin)堵頭(tou)板(ban)(ban)與樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)及鋼(gang)(gang)梁(liang)點(dian)焊(han)。如果是(shi)帶弧形(xing)區(qu)樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)異型裁切(qie)采(cai)用(yong)(yong)(yong)等(deng)離子切(qie)割機切(qie)割，其切(qie)口光滑，表(biao)面鍍(du)鋅(xin)層完整。樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)焊(han)接采(cai)用(yong)(yong)(yong)手工(gong)電(dian)弧點(dian)焊(han)，焊(han)條為Ｅ4303，直徑3.2mm，熔透焊(han)接點(dian)為16mm.原(yuan)設(she)(she)計焊(han)點(dian)間距305mm，后(hou)將焊(han)點(dian)增加1倍(bei)，以確(que)保操作人員行走時樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)不(bu)變形(xing)，混凝土(tu)澆筑(zhu)時樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)端(duan)頭(tou)不(bu)漏漿。當(dang)樓(lou)面層結(jie)構(gou)標(biao)高變化不(bu)一致時，采(cai)取加焊(han)型鋼(gang)(gang)措施，使(shi)水平結(jie)構(gou)呈臺階過渡，當(dang)降低標(biao)高時工(gong)字梁(liang)腹板(ban)(ban)加焊(han)角鋼(gang)(gang)；抬升(sheng)標(biao)高時工(gong)字梁(liang)翼緣加焊(han)槽鋼(gang)(gang)。  

樓承板的特點 

1：適應主體鋼結構快速施工的(de)要(yao)求，能夠在短時間內(nei)提供(gong)堅定的(de)作(zuo)業平臺(tai)，并可采用(yong)多(duo)個樓層鋪(pu)設(she)壓(ya)型鋼板(ban)(ban)，分層澆筑混凝土板(ban)(ban)的(de)流(liu)水施工。 

2：在使用(yong)階(jie)段樓承板(ban)作為混凝土樓板(ban)的(de)受拉鋼筋，也提高了樓板(ban)的(de)剛度，節省了鋼筋和混凝土的(de)用(yong)量。 

3：壓(ya)型板表(biao)面壓(ya)紋使樓承(cheng)板與混凝(ning)土之間產生(sheng)最大的結合力，使二者形成整體，配以(yi)加勁肋，使樓承(cheng)板系(xi)統(tong)具有高強承(cheng)載力。 

4：在懸(xuan)(xuan)臂條件下，樓承板(ban)僅作(zuo)為永久性(xing)模板(ban)。懸(xuan)(xuan)挑的(de)長度(du)可根據樓承板(ban)的(de)截面(mian)特(te)性(xing)來定。為了防(fang)止懸(xuan)(xuan)挑板(ban)的(de)開裂(lie)，需在支(zhi)座處依結(jie)構工程師的(de)設計(ji)配上負筋。 

5：本(ben)公司樓承板已通過(guo)國家(jia)固定滅火系統及耐火構件(jian)質量檢測(ce)中(zhong)心的耐火極限檢測(ce)，作為組合樓承板無(wu)需(xu)防火噴涂，因此大大降低了(le)工程造價。
