蘭州樓承板，也叫壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)板(ban)(ban)、鋼(gang)承板(ban)(ban)、鋼(gang)樓(lou)承板(ban)(ban)。最早叫壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)板(ban)(ban)，即所有經壓(ya)(ya)(ya)板(ban)(ban)機壓(ya)(ya)(ya)制(zhi)成型(xing)(xing)的(de)(de)鋼(gang)板(ban)(ban)的(de)(de)統稱。樓(lou)承板(ban)(ban)是(shi)采用(yong)鍍鋅(xin)鋼(gang)板(ban)(ban)經輥壓(ya)(ya)(ya)冷彎成型(xing)(xing)，其截面(mian)成V型(xing)(xing)、U型(xing)(xing)、梯形(xing)(xing)或類似這幾種形(xing)(xing)狀的(de)(de)波(bo)形(xing)(xing)，主(zhu)要用(yong)作永久性模板(ban)(ban)，也可被選為(wei)其他用(yong)途。最早的(de)(de)壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)板(ban)(ban)主(zhu)要是(shi)用(yong)于廠房屋面(mian)的(de)(de)屋面(mian)板(ban)(ban)，后(hou)面(mian)有用(yong)于樓(lou)層(ceng)的(de)(de)壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)板(ban)(ban)后(hou)逐漸分類稱為(wei)樓(lou)承板(ban)(ban)。  

樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)型材厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高5 1 mm ~76mm.工(gong)程樓(lou)(lou)(lou)(lou)(lou)面樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)與(yu)鋼(gang)(gang)(gang)筋混(hun)凝土(tu)結(jie)構共同作(zuo)用(yong)(yong)，系復合結(jie)構。樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)鋪(pu)設與(yu)鋼(gang)(gang)(gang)梁(liang)(liang)連接(jie)，板(ban)(ban)(ban)(ban)端(duan)頭(tou)(tou)與(yu)鋼(gang)(gang)(gang)梁(liang)(liang)熔(rong)透點焊(han)(han)，中(zhong)間采用(yong)(yong)栓釘與(yu)鋼(gang)(gang)(gang)梁(liang)(liang)穿透熔(rong)焊(han)(han)；樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)間用(yong)(yong)專用(yong)(yong)夾(jia)緊(jin)鉗咬合壓孔連接(jie)；堵頭(tou)(tou)用(yong)(yong)專用(yong)(yong)鍍鋅堵頭(tou)(tou)板(ban)(ban)(ban)(ban)與(yu)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)及(ji)鋼(gang)(gang)(gang)梁(liang)(liang)點焊(han)(han)。如果是帶弧形區樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)異型裁切(qie)(qie)采用(yong)(yong)等離子切(qie)(qie)割機切(qie)(qie)割，其切(qie)(qie)口(kou)光滑，表(biao)面鍍鋅層(ceng)完整。樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)焊(han)(han)接(jie)采用(yong)(yong)手工(gong)電弧點焊(han)(han)，焊(han)(han)條為Ｅ4303，直徑3.2mm，熔(rong)透焊(han)(han)接(jie)點為16mm.原設計焊(han)(han)點間距305mm，后將(jiang)焊(han)(han)點增加(jia)1倍，以(yi)確保操作(zuo)人員行(xing)走(zou)時(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)不變(bian)形，混(hun)凝土(tu)澆(jiao)筑(zhu)時(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)端(duan)頭(tou)(tou)不漏漿。當樓(lou)(lou)(lou)(lou)(lou)面層(ceng)結(jie)構標高變(bian)化不一致(zhi)時(shi)，采取加(jia)焊(han)(han)型鋼(gang)(gang)(gang)措施，使水平(ping)結(jie)構呈臺階過渡，當降低(di)標高時(shi)工(gong)字梁(liang)(liang)腹板(ban)(ban)(ban)(ban)加(jia)焊(han)(han)角鋼(gang)(gang)(gang)；抬(tai)升標高時(shi)工(gong)字梁(liang)(liang)翼緣加(jia)焊(han)(han)槽鋼(gang)(gang)(gang)。  

樓承板的特點 

1：適應主體鋼結構快速施(shi)工(gong)的要(yao)求，能夠在短時間(jian)內提供(gong)堅定的作(zuo)業平臺，并可采(cai)用多個樓層鋪(pu)設壓型鋼板(ban)，分層澆(jiao)筑混凝土板(ban)的流水施(shi)工(gong)。 

2：在使用階段樓承板作(zuo)為混(hun)凝(ning)土(tu)樓板的(de)(de)受拉鋼筋，也提高(gao)了樓板的(de)(de)剛度(du)，節省了鋼筋和混(hun)凝(ning)土(tu)的(de)(de)用量(liang)。 

3：壓型(xing)板(ban)(ban)表面壓紋使(shi)樓承(cheng)板(ban)(ban)與混凝土之間產生最(zui)大的(de)結(jie)合力，使(shi)二(er)者形成整(zheng)體，配以加勁肋(lei)，使(shi)樓承(cheng)板(ban)(ban)系統(tong)具有(you)高(gao)強承(cheng)載力。 

4：在懸(xuan)臂條件下，樓承板(ban)僅(jin)作為(wei)永久(jiu)性模板(ban)。懸(xuan)挑的(de)長度可根據樓承板(ban)的(de)截面特性來定。為(wei)了防止懸(xuan)挑板(ban)的(de)開裂，需在支座處依結構(gou)工(gong)程師的(de)設計配上(shang)負筋。 

5：本公司樓承(cheng)板已通過國家固定滅火(huo)(huo)系(xi)統及耐(nai)火(huo)(huo)構件質量檢(jian)測中心(xin)的耐(nai)火(huo)(huo)極限檢(jian)測，作為組合樓承(cheng)板無需防火(huo)(huo)噴涂，因此大(da)大(da)降低了工程造價。
