蘭州樓承板，也叫(jiao)壓(ya)(ya)(ya)型鋼(gang)(gang)(gang)板(ban)(ban)、鋼(gang)(gang)(gang)承(cheng)(cheng)板(ban)(ban)、鋼(gang)(gang)(gang)樓承(cheng)(cheng)板(ban)(ban)。最(zui)早(zao)叫(jiao)壓(ya)(ya)(ya)型鋼(gang)(gang)(gang)板(ban)(ban)，即所有(you)經(jing)壓(ya)(ya)(ya)板(ban)(ban)機壓(ya)(ya)(ya)制成(cheng)型的(de)鋼(gang)(gang)(gang)板(ban)(ban)的(de)統稱。樓承(cheng)(cheng)板(ban)(ban)是采用(yong)(yong)鍍鋅鋼(gang)(gang)(gang)板(ban)(ban)經(jing)輥(gun)壓(ya)(ya)(ya)冷(leng)彎成(cheng)型，其(qi)截面(mian)成(cheng)V型、U型、梯形或類似這幾種(zhong)形狀的(de)波形，主(zhu)要用(yong)(yong)作永久性模板(ban)(ban)，也可(ke)被(bei)選為(wei)其(qi)他用(yong)(yong)途。最(zui)早(zao)的(de)壓(ya)(ya)(ya)型鋼(gang)(gang)(gang)板(ban)(ban)主(zhu)要是用(yong)(yong)于廠房屋面(mian)的(de)屋面(mian)板(ban)(ban)，后面(mian)有(you)用(yong)(yong)于樓層的(de)壓(ya)(ya)(ya)型鋼(gang)(gang)(gang)板(ban)(ban)后逐漸分(fen)類稱為(wei)樓承(cheng)(cheng)板(ban)(ban)。  

樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)型(xing)(xing)材厚(hou)0.8mm、1.0mm、1.2mm寬(kuan)688mm~940mm，高(gao)5 1 mm ~76mm.工(gong)程樓(lou)(lou)(lou)(lou)面樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)與(yu)(yu)鋼筋混凝土(tu)結構共同作(zuo)用，系復合結構。樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)鋪設(she)與(yu)(yu)鋼梁(liang)連接(jie)，板(ban)(ban)(ban)(ban)(ban)端頭(tou)與(yu)(yu)鋼梁(liang)熔(rong)透點(dian)(dian)焊(han)(han)(han)，中間(jian)采(cai)用栓釘與(yu)(yu)鋼梁(liang)穿透熔(rong)焊(han)(han)(han)；樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)間(jian)用專用夾緊鉗咬合壓孔連接(jie)；堵(du)頭(tou)用專用鍍鋅(xin)堵(du)頭(tou)板(ban)(ban)(ban)(ban)(ban)與(yu)(yu)樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)及鋼梁(liang)點(dian)(dian)焊(han)(han)(han)。如果是帶(dai)弧形區樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)異(yi)型(xing)(xing)裁(cai)切(qie)采(cai)用等離子切(qie)割機切(qie)割，其切(qie)口光(guang)滑，表面鍍鋅(xin)層完(wan)整。樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)焊(han)(han)(han)接(jie)采(cai)用手工(gong)電弧點(dian)(dian)焊(han)(han)(han)，焊(han)(han)(han)條為Ｅ4303，直徑(jing)3.2mm，熔(rong)透焊(han)(han)(han)接(jie)點(dian)(dian)為16mm.原(yuan)設(she)計焊(han)(han)(han)點(dian)(dian)間(jian)距305mm，后(hou)將焊(han)(han)(han)點(dian)(dian)增加1倍(bei)，以確保操(cao)作(zuo)人員行走時(shi)樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)不(bu)變(bian)形，混凝土(tu)澆筑(zhu)時(shi)樓(lou)(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)端頭(tou)不(bu)漏漿(jiang)。當(dang)樓(lou)(lou)(lou)(lou)面層結構標高(gao)變(bian)化不(bu)一致時(shi)，采(cai)取(qu)加焊(han)(han)(han)型(xing)(xing)鋼措施(shi)，使(shi)水(shui)平結構呈臺階(jie)過(guo)渡，當(dang)降低標高(gao)時(shi)工(gong)字梁(liang)腹(fu)板(ban)(ban)(ban)(ban)(ban)加焊(han)(han)(han)角(jiao)鋼；抬(tai)升標高(gao)時(shi)工(gong)字梁(liang)翼緣加焊(han)(han)(han)槽鋼。  

樓承(cheng)板(ban)的特點 

1：適應主體鋼結構快速施工的(de)要求(qiu)，能夠在(zai)短時間內提供堅定的(de)作(zuo)業平臺(tai)，并可采(cai)用多個樓(lou)層鋪設(she)壓型鋼板(ban)，分層澆(jiao)筑混凝土板(ban)的(de)流水施工。 

2：在使用(yong)階(jie)段樓(lou)(lou)(lou)承(cheng)板(ban)作為混(hun)凝土(tu)樓(lou)(lou)(lou)板(ban)的受拉(la)鋼筋(jin)，也提(ti)高了樓(lou)(lou)(lou)板(ban)的剛度，節省了鋼筋(jin)和混(hun)凝土(tu)的用(yong)量。 

3：壓型(xing)板(ban)(ban)表面壓紋使樓承板(ban)(ban)與混凝(ning)土之間(jian)產生(sheng)最(zui)大的結合力，使二(er)者形成整體，配以加勁肋，使樓承板(ban)(ban)系統具(ju)有高(gao)強承載力。 

4：在懸臂條件下，樓承板僅作(zuo)為(wei)永久性模板。懸挑的(de)長度可根據樓承板的(de)截(jie)面特性來(lai)定。為(wei)了(le)防(fang)止(zhi)懸挑板的(de)開裂，需(xu)在支座處依結構工程(cheng)師的(de)設計配上(shang)負筋。 

5：本公司樓承板已通過國家固定滅火系統及耐(nai)火構件質(zhi)量檢(jian)測(ce)中心的耐(nai)火極限檢(jian)測(ce)，作為組合(he)樓承板無需防火噴(pen)涂，因此大(da)大(da)降低了工程造(zao)價。
