蘭州樓承板，也叫壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)(ban)、鋼(gang)(gang)承(cheng)板(ban)(ban)(ban)(ban)、鋼(gang)(gang)樓承(cheng)板(ban)(ban)(ban)(ban)。最早叫壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)(ban)，即所有經壓(ya)板(ban)(ban)(ban)(ban)機壓(ya)制成(cheng)型的(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)的(de)統(tong)稱。樓承(cheng)板(ban)(ban)(ban)(ban)是(shi)(shi)采(cai)用(yong)鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)經輥壓(ya)冷彎成(cheng)型，其(qi)截面(mian)(mian)成(cheng)V型、U型、梯形(xing)或類似這(zhe)幾種(zhong)形(xing)狀的(de)波形(xing)，主(zhu)要用(yong)作永久(jiu)性模板(ban)(ban)(ban)(ban)，也可被選為(wei)其(qi)他(ta)用(yong)途。最早的(de)壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)(ban)主(zhu)要是(shi)(shi)用(yong)于廠房屋面(mian)(mian)的(de)屋面(mian)(mian)板(ban)(ban)(ban)(ban)，后面(mian)(mian)有用(yong)于樓層的(de)壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)(ban)后逐漸分類稱為(wei)樓承(cheng)板(ban)(ban)(ban)(ban)。  

樓(lou)承(cheng)(cheng)(cheng)(cheng)板型(xing)(xing)材厚(hou)0.8mm、1.0mm、1.2mm寬688mm~940mm，高(gao)(gao)5 1 mm ~76mm.工程樓(lou)面樓(lou)承(cheng)(cheng)(cheng)(cheng)板與鋼筋混凝土(tu)(tu)結(jie)(jie)構共同作用(yong)(yong)(yong)，系復合(he)結(jie)(jie)構。樓(lou)承(cheng)(cheng)(cheng)(cheng)板鋪設與鋼梁(liang)連接(jie)，板端頭與鋼梁(liang)熔透(tou)點(dian)(dian)焊(han)(han)(han)，中間采(cai)(cai)用(yong)(yong)(yong)栓(shuan)釘(ding)與鋼梁(liang)穿透(tou)熔焊(han)(han)(han)；樓(lou)承(cheng)(cheng)(cheng)(cheng)板間用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)夾(jia)緊鉗咬(yao)合(he)壓孔連接(jie)；堵頭用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)鍍鋅堵頭板與樓(lou)承(cheng)(cheng)(cheng)(cheng)板及鋼梁(liang)點(dian)(dian)焊(han)(han)(han)。如果(guo)是帶弧形(xing)區(qu)樓(lou)承(cheng)(cheng)(cheng)(cheng)板異型(xing)(xing)裁切(qie)采(cai)(cai)用(yong)(yong)(yong)等離(li)子切(qie)割(ge)機切(qie)割(ge)，其切(qie)口光滑(hua)，表(biao)面鍍鋅層完整。樓(lou)承(cheng)(cheng)(cheng)(cheng)板焊(han)(han)(han)接(jie)采(cai)(cai)用(yong)(yong)(yong)手(shou)工電弧點(dian)(dian)焊(han)(han)(han)，焊(han)(han)(han)條為(wei)Ｅ4303，直徑(jing)3.2mm，熔透(tou)焊(han)(han)(han)接(jie)點(dian)(dian)為(wei)16mm.原設計焊(han)(han)(han)點(dian)(dian)間距305mm，后(hou)將焊(han)(han)(han)點(dian)(dian)增加(jia)1倍，以確保操作人(ren)員(yuan)行走時(shi)樓(lou)承(cheng)(cheng)(cheng)(cheng)板不(bu)變形(xing)，混凝土(tu)(tu)澆筑(zhu)時(shi)樓(lou)承(cheng)(cheng)(cheng)(cheng)板端頭不(bu)漏漿(jiang)。當(dang)樓(lou)面層結(jie)(jie)構標高(gao)(gao)變化不(bu)一致時(shi)，采(cai)(cai)取加(jia)焊(han)(han)(han)型(xing)(xing)鋼措施，使水(shui)平結(jie)(jie)構呈(cheng)臺階(jie)過渡，當(dang)降低標高(gao)(gao)時(shi)工字梁(liang)腹板加(jia)焊(han)(han)(han)角(jiao)鋼；抬升標高(gao)(gao)時(shi)工字梁(liang)翼緣加(jia)焊(han)(han)(han)槽鋼。  

樓承板(ban)的特點(dian) 

1：適應主體鋼結構快(kuai)速施(shi)工(gong)的(de)(de)要求，能夠在短(duan)時間內提供堅定的(de)(de)作業平臺，并(bing)可(ke)采用多個樓層(ceng)鋪設壓型鋼板，分層(ceng)澆筑混凝土板的(de)(de)流水(shui)施(shi)工(gong)。 

2：在(zai)使用階段樓承板(ban)作為混凝土(tu)樓板(ban)的受拉鋼筋(jin)，也提高了(le)樓板(ban)的剛度(du)，節省了(le)鋼筋(jin)和混凝土(tu)的用量。 

3：壓(ya)型板表面壓(ya)紋使(shi)(shi)樓承板與混凝(ning)土之間產生最大的結合力，使(shi)(shi)二者形(xing)成(cheng)整體，配以加勁肋，使(shi)(shi)樓承板系統具有高強承載力。 

4：在(zai)懸(xuan)臂條件下，樓承(cheng)板僅作為(wei)永久性(xing)模板。懸(xuan)挑的(de)(de)長(chang)度可根據(ju)樓承(cheng)板的(de)(de)截面特性(xing)來定。為(wei)了(le)防止(zhi)懸(xuan)挑板的(de)(de)開裂(lie)，需在(zai)支座處(chu)依(yi)結(jie)構工程師(shi)的(de)(de)設計配上負筋(jin)。 

5：本公司樓(lou)承板(ban)已通過國家固定滅(mie)火(huo)系統(tong)及耐火(huo)構件質(zhi)量(liang)檢測(ce)中心(xin)的耐火(huo)極限檢測(ce)，作(zuo)為組(zu)合樓(lou)承板(ban)無(wu)需防火(huo)噴(pen)涂，因此大(da)大(da)降低(di)了工程造價。
