蘭州樓承板，也(ye)叫壓型(xing)(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)、鋼(gang)(gang)(gang)(gang)承板(ban)(ban)(ban)、鋼(gang)(gang)(gang)(gang)樓承板(ban)(ban)(ban)。最早叫壓型(xing)(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，即所有經(jing)壓板(ban)(ban)(ban)機壓制成(cheng)型(xing)(xing)的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)的(de)統稱。樓承板(ban)(ban)(ban)是(shi)(shi)采用(yong)鍍鋅鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)經(jing)輥壓冷(leng)彎成(cheng)型(xing)(xing)，其(qi)截(jie)面成(cheng)V型(xing)(xing)、U型(xing)(xing)、梯形或類(lei)似這幾種形狀的(de)波形，主要用(yong)作永久性(xing)模板(ban)(ban)(ban)，也(ye)可被選(xuan)為(wei)其(qi)他用(yong)途。最早的(de)壓型(xing)(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)主要是(shi)(shi)用(yong)于廠房屋面的(de)屋面板(ban)(ban)(ban)，后(hou)面有用(yong)于樓層的(de)壓型(xing)(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)后(hou)逐漸分類(lei)稱為(wei)樓承板(ban)(ban)(ban)。  

樓(lou)承(cheng)板(ban)(ban)(ban)型材(cai)厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高(gao)(gao)(gao)5 1 mm ~76mm.工程樓(lou)面(mian)樓(lou)承(cheng)板(ban)(ban)(ban)與(yu)(yu)(yu)鋼筋混凝(ning)土(tu)結構共(gong)同作用，系復合結構。樓(lou)承(cheng)板(ban)(ban)(ban)鋪設(she)與(yu)(yu)(yu)鋼梁(liang)(liang)連(lian)接(jie)，板(ban)(ban)(ban)端(duan)頭(tou)與(yu)(yu)(yu)鋼梁(liang)(liang)熔(rong)(rong)透(tou)點(dian)焊(han)(han)(han)，中間采(cai)用栓(shuan)釘與(yu)(yu)(yu)鋼梁(liang)(liang)穿透(tou)熔(rong)(rong)焊(han)(han)(han)；樓(lou)承(cheng)板(ban)(ban)(ban)間用專(zhuan)用夾緊鉗咬(yao)合壓(ya)孔(kong)連(lian)接(jie)；堵(du)頭(tou)用專(zhuan)用鍍(du)(du)鋅堵(du)頭(tou)板(ban)(ban)(ban)與(yu)(yu)(yu)樓(lou)承(cheng)板(ban)(ban)(ban)及鋼梁(liang)(liang)點(dian)焊(han)(han)(han)。如果是帶弧(hu)形(xing)區樓(lou)承(cheng)板(ban)(ban)(ban)異(yi)型裁切(qie)(qie)(qie)采(cai)用等離子(zi)切(qie)(qie)(qie)割機切(qie)(qie)(qie)割，其切(qie)(qie)(qie)口光滑，表面(mian)鍍(du)(du)鋅層完整。樓(lou)承(cheng)板(ban)(ban)(ban)焊(han)(han)(han)接(jie)采(cai)用手工電弧(hu)點(dian)焊(han)(han)(han)，焊(han)(han)(han)條為(wei)(wei)Ｅ4303，直(zhi)徑3.2mm，熔(rong)(rong)透(tou)焊(han)(han)(han)接(jie)點(dian)為(wei)(wei)16mm.原設(she)計焊(han)(han)(han)點(dian)間距305mm，后將焊(han)(han)(han)點(dian)增加(jia)(jia)1倍(bei)，以確保操作人員行走時樓(lou)承(cheng)板(ban)(ban)(ban)不(bu)變形(xing)，混凝(ning)土(tu)澆筑時樓(lou)承(cheng)板(ban)(ban)(ban)端(duan)頭(tou)不(bu)漏(lou)漿。當(dang)樓(lou)面(mian)層結構標高(gao)(gao)(gao)變化不(bu)一致(zhi)時，采(cai)取加(jia)(jia)焊(han)(han)(han)型鋼措施，使水(shui)平(ping)結構呈臺階過渡，當(dang)降低(di)標高(gao)(gao)(gao)時工字梁(liang)(liang)腹板(ban)(ban)(ban)加(jia)(jia)焊(han)(han)(han)角鋼；抬升標高(gao)(gao)(gao)時工字梁(liang)(liang)翼緣(yuan)加(jia)(jia)焊(han)(han)(han)槽鋼。  

樓(lou)承板(ban)的特(te)點 

1：適應主體鋼結構快速施工的(de)要求，能夠在(zai)短時間內提供堅定的(de)作業平臺，并(bing)可(ke)采用多個(ge)樓層鋪(pu)設壓型鋼板(ban)，分層澆筑(zhu)混凝土(tu)板(ban)的(de)流水施工。 

2：在(zai)使用階(jie)段樓承(cheng)板作為混凝土樓板的受拉鋼(gang)筋，也提高(gao)了(le)(le)樓板的剛度，節省了(le)(le)鋼(gang)筋和混凝土的用量。 

3：壓(ya)型(xing)板表面(mian)壓(ya)紋使(shi)樓(lou)承板與混凝(ning)土之間產生最大的結合(he)力(li)，使(shi)二者形成整體，配(pei)以加勁肋(lei)，使(shi)樓(lou)承板系統具有高強承載力(li)。 

4：在(zai)懸臂條件下，樓承板(ban)僅作為永久性模(mo)板(ban)。懸挑的(de)長度可根據樓承板(ban)的(de)截面特性來定。為了防止(zhi)懸挑板(ban)的(de)開裂，需(xu)在(zai)支(zhi)座處依結構工(gong)程師(shi)的(de)設(she)計配(pei)上負筋。 

5：本(ben)公司樓承(cheng)板(ban)已(yi)通(tong)過國家固定滅火系統及耐(nai)火構(gou)件質量檢測(ce)中心的耐(nai)火極限檢測(ce)，作為組(zu)合樓承(cheng)板(ban)無需防火噴涂，因此大大降低(di)了工(gong)程造價(jia)。
