蘭州樓承板，也(ye)叫壓型(xing)鋼(gang)(gang)板、鋼(gang)(gang)承板、鋼(gang)(gang)樓承板。最早(zao)叫壓型(xing)鋼(gang)(gang)板，即所有經壓板機壓制成(cheng)型(xing)的鋼(gang)(gang)板的統稱(cheng)。樓承板是采用(yong)(yong)(yong)鍍鋅鋼(gang)(gang)板經輥壓冷彎成(cheng)型(xing)，其截面成(cheng)V型(xing)、U型(xing)、梯(ti)形或(huo)類似這(zhe)幾種形狀(zhuang)的波形，主要(yao)用(yong)(yong)(yong)作永久性模板，也(ye)可被(bei)選為其他用(yong)(yong)(yong)途。最早(zao)的壓型(xing)鋼(gang)(gang)板主要(yao)是用(yong)(yong)(yong)于廠房屋面的屋面板，后面有用(yong)(yong)(yong)于樓層(ceng)的壓型(xing)鋼(gang)(gang)板后逐漸分類稱(cheng)為樓承板。  

樓(lou)承(cheng)(cheng)板(ban)(ban)型(xing)材厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高(gao)5 1 mm ~76mm.工程(cheng)樓(lou)面樓(lou)承(cheng)(cheng)板(ban)(ban)與鋼(gang)(gang)(gang)筋(jin)混凝(ning)土結構(gou)共同作用(yong)，系(xi)復合(he)(he)結構(gou)。樓(lou)承(cheng)(cheng)板(ban)(ban)鋪(pu)設與鋼(gang)(gang)(gang)梁(liang)連接(jie)，板(ban)(ban)端(duan)頭與鋼(gang)(gang)(gang)梁(liang)熔透(tou)點(dian)焊(han)(han)，中(zhong)間(jian)(jian)采用(yong)栓釘與鋼(gang)(gang)(gang)梁(liang)穿透(tou)熔焊(han)(han)；樓(lou)承(cheng)(cheng)板(ban)(ban)間(jian)(jian)用(yong)專(zhuan)用(yong)夾緊鉗咬合(he)(he)壓孔連接(jie)；堵頭用(yong)專(zhuan)用(yong)鍍(du)鋅(xin)堵頭板(ban)(ban)與樓(lou)承(cheng)(cheng)板(ban)(ban)及鋼(gang)(gang)(gang)梁(liang)點(dian)焊(han)(han)。如果是帶弧(hu)(hu)形區樓(lou)承(cheng)(cheng)板(ban)(ban)異型(xing)裁切采用(yong)等離子切割機切割，其切口(kou)光滑，表面鍍(du)鋅(xin)層完(wan)整。樓(lou)承(cheng)(cheng)板(ban)(ban)焊(han)(han)接(jie)采用(yong)手(shou)工電弧(hu)(hu)點(dian)焊(han)(han)，焊(han)(han)條為Ｅ4303，直徑3.2mm，熔透(tou)焊(han)(han)接(jie)點(dian)為16mm.原設計焊(han)(han)點(dian)間(jian)(jian)距305mm，后將焊(han)(han)點(dian)增加1倍(bei)，以確保(bao)操作人員行(xing)走時(shi)(shi)樓(lou)承(cheng)(cheng)板(ban)(ban)不變形，混凝(ning)土澆筑時(shi)(shi)樓(lou)承(cheng)(cheng)板(ban)(ban)端(duan)頭不漏漿。當(dang)樓(lou)面層結構(gou)標高(gao)變化不一致時(shi)(shi)，采取加焊(han)(han)型(xing)鋼(gang)(gang)(gang)措施，使水(shui)平結構(gou)呈臺階過渡(du)，當(dang)降低標高(gao)時(shi)(shi)工字梁(liang)腹板(ban)(ban)加焊(han)(han)角(jiao)鋼(gang)(gang)(gang)；抬升標高(gao)時(shi)(shi)工字梁(liang)翼緣加焊(han)(han)槽鋼(gang)(gang)(gang)。  

樓(lou)承板的特點 

1：適應主體鋼結構快(kuai)速施(shi)(shi)工(gong)的要求，能夠在短時間內提(ti)供堅定的作(zuo)業平臺，并可采用多個樓層(ceng)鋪設壓(ya)型鋼(gang)板，分(fen)層(ceng)澆筑混凝土板的流(liu)水施(shi)(shi)工(gong)。 

2：在使用階段(duan)樓承板(ban)(ban)作(zuo)為混凝土樓板(ban)(ban)的(de)受拉鋼筋，也提高了(le)(le)樓板(ban)(ban)的(de)剛度，節省了(le)(le)鋼筋和混凝土的(de)用量。 

3：壓型板(ban)(ban)表面壓紋使樓承(cheng)板(ban)(ban)與混凝土之間產(chan)生最大(da)的結合力(li)，使二者形(xing)成整體，配以加勁肋，使樓承(cheng)板(ban)(ban)系統具有(you)高強承(cheng)載力(li)。 

4：在(zai)懸臂條件下，樓(lou)承板(ban)僅作(zuo)為(wei)永久性(xing)模板(ban)。懸挑(tiao)的(de)(de)(de)長度可根據樓(lou)承板(ban)的(de)(de)(de)截面特性(xing)來定(ding)。為(wei)了防止(zhi)懸挑(tiao)板(ban)的(de)(de)(de)開裂，需(xu)在(zai)支(zhi)座處依(yi)結構工程(cheng)師的(de)(de)(de)設計配(pei)上負(fu)筋。 

5：本公司樓(lou)承(cheng)板已通過國家固定滅火(huo)系統及(ji)耐火(huo)構(gou)件(jian)質量(liang)檢測中心的耐火(huo)極限檢測，作為組合樓(lou)承(cheng)板無需防火(huo)噴涂，因此大大降低了工(gong)程造價。
