蘭州樓承板，也叫壓型(xing)(xing)(xing)鋼(gang)板(ban)(ban)、鋼(gang)承(cheng)板(ban)(ban)、鋼(gang)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)。最(zui)早叫壓型(xing)(xing)(xing)鋼(gang)板(ban)(ban)，即所有經壓板(ban)(ban)機壓制成型(xing)(xing)(xing)的(de)鋼(gang)板(ban)(ban)的(de)統(tong)稱(cheng)。樓(lou)(lou)(lou)承(cheng)板(ban)(ban)是采用鍍鋅鋼(gang)板(ban)(ban)經輥壓冷(leng)彎(wan)成型(xing)(xing)(xing)，其(qi)截面成V型(xing)(xing)(xing)、U型(xing)(xing)(xing)、梯形(xing)或類似這幾種形(xing)狀的(de)波(bo)形(xing)，主要(yao)用作永久(jiu)性(xing)模板(ban)(ban)，也可被選(xuan)為(wei)其(qi)他用途。最(zui)早的(de)壓型(xing)(xing)(xing)鋼(gang)板(ban)(ban)主要(yao)是用于(yu)廠房屋面的(de)屋面板(ban)(ban)，后面有用于(yu)樓(lou)(lou)(lou)層的(de)壓型(xing)(xing)(xing)鋼(gang)板(ban)(ban)后逐(zhu)漸(jian)分類稱(cheng)為(wei)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)。  

樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)型(xing)材厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高(gao)5 1 mm ~76mm.工程樓(lou)(lou)面樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)與鋼(gang)筋混凝土結(jie)(jie)構(gou)共同作用(yong)(yong)，系復合(he)結(jie)(jie)構(gou)。樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)鋪設與鋼(gang)梁(liang)連(lian)接(jie)，板(ban)端頭(tou)(tou)與鋼(gang)梁(liang)熔(rong)透點(dian)(dian)焊，中間采(cai)(cai)用(yong)(yong)栓釘與鋼(gang)梁(liang)穿透熔(rong)焊；樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)間用(yong)(yong)專(zhuan)用(yong)(yong)夾緊鉗(qian)咬合(he)壓孔連(lian)接(jie)；堵頭(tou)(tou)用(yong)(yong)專(zhuan)用(yong)(yong)鍍鋅(xin)堵頭(tou)(tou)板(ban)與樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)及鋼(gang)梁(liang)點(dian)(dian)焊。如果是(shi)帶(dai)弧形(xing)區樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)異型(xing)裁(cai)切(qie)采(cai)(cai)用(yong)(yong)等離子切(qie)割機切(qie)割，其(qi)切(qie)口(kou)光滑(hua)，表面鍍鋅(xin)層(ceng)完整(zheng)。樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)焊接(jie)采(cai)(cai)用(yong)(yong)手工電弧點(dian)(dian)焊，焊條(tiao)為Ｅ4303，直徑(jing)3.2mm，熔(rong)透焊接(jie)點(dian)(dian)為16mm.原(yuan)設計焊點(dian)(dian)間距(ju)305mm，后(hou)將焊點(dian)(dian)增加(jia)1倍，以確保(bao)操作人(ren)員行(xing)走時樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)不(bu)變形(xing)，混凝土澆(jiao)筑時樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)端頭(tou)(tou)不(bu)漏漿。當樓(lou)(lou)面層(ceng)結(jie)(jie)構(gou)標高(gao)變化不(bu)一(yi)致(zhi)時，采(cai)(cai)取加(jia)焊型(xing)鋼(gang)措施(shi)，使水平(ping)結(jie)(jie)構(gou)呈臺(tai)階過渡，當降低(di)標高(gao)時工字(zi)梁(liang)腹板(ban)加(jia)焊角鋼(gang)；抬(tai)升(sheng)標高(gao)時工字(zi)梁(liang)翼緣加(jia)焊槽(cao)鋼(gang)。  

樓承板(ban)的特點 

1：適應主體鋼結構快速施工(gong)的要求(qiu)，能夠在(zai)短時間內提供堅定的作業平臺，并可采用多個樓層(ceng)(ceng)鋪設(she)壓(ya)型(xing)鋼板，分層(ceng)(ceng)澆筑混(hun)凝土板的流水施工(gong)。 

2：在使(shi)用階段樓(lou)(lou)承(cheng)板作為混凝土(tu)樓(lou)(lou)板的受拉鋼筋，也(ye)提高了(le)樓(lou)(lou)板的剛(gang)度，節省(sheng)了(le)鋼筋和混凝土(tu)的用量。 

3：壓型板(ban)表(biao)面壓紋使樓承(cheng)(cheng)板(ban)與混凝土之(zhi)間產生最大的結合力，使二者形(xing)成整體，配以加勁肋，使樓承(cheng)(cheng)板(ban)系統具有高強承(cheng)(cheng)載力。 

4：在懸(xuan)臂(bei)條件下，樓(lou)承板(ban)僅作為永久性模板(ban)。懸(xuan)挑的(de)(de)長度可根(gen)據樓(lou)承板(ban)的(de)(de)截面特性來定。為了防止懸(xuan)挑板(ban)的(de)(de)開裂，需在支座處依(yi)結構(gou)工程師的(de)(de)設計配上負筋(jin)。 

5：本公司樓承(cheng)板(ban)已通過國家固定滅火(huo)系統及耐(nai)火(huo)構件(jian)質(zhi)量檢(jian)測中心的耐(nai)火(huo)極限檢(jian)測，作為組合樓承(cheng)板(ban)無需防火(huo)噴涂，因此大(da)大(da)降(jiang)低了工程造價。
