蘭州樓承板，也叫壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)、鋼(gang)(gang)(gang)承板(ban)(ban)(ban)(ban)、鋼(gang)(gang)(gang)樓(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)。最(zui)早(zao)叫壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，即(ji)所(suo)有經(jing)壓(ya)(ya)(ya)板(ban)(ban)(ban)(ban)機(ji)壓(ya)(ya)(ya)制成(cheng)型(xing)(xing)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)統稱。樓(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)是采用鍍鋅鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)經(jing)輥(gun)壓(ya)(ya)(ya)冷彎成(cheng)型(xing)(xing)，其(qi)(qi)截面成(cheng)V型(xing)(xing)、U型(xing)(xing)、梯形(xing)或類似這幾種形(xing)狀的(de)(de)波(bo)形(xing)，主要用作永久性模板(ban)(ban)(ban)(ban)，也可被(bei)選為其(qi)(qi)他用途(tu)。最(zui)早(zao)的(de)(de)壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)主要是用于(yu)(yu)廠(chang)房屋面的(de)(de)屋面板(ban)(ban)(ban)(ban)，后面有用于(yu)(yu)樓(lou)(lou)(lou)層的(de)(de)壓(ya)(ya)(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)后逐漸(jian)分類稱為樓(lou)(lou)(lou)承板(ban)(ban)(ban)(ban)。  

樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)型(xing)材厚0.8mm、1.0mm、1.2mm寬688mm~940mm，高5 1 mm ~76mm.工(gong)程(cheng)樓(lou)(lou)(lou)面(mian)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)與鋼(gang)筋(jin)混凝土結(jie)構(gou)(gou)共同作(zuo)用(yong)(yong)(yong)(yong)(yong)(yong)，系(xi)復合結(jie)構(gou)(gou)。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)鋪(pu)設與鋼(gang)梁(liang)(liang)連接，板(ban)(ban)(ban)端頭(tou)與鋼(gang)梁(liang)(liang)熔(rong)透點(dian)(dian)焊(han)，中間(jian)采用(yong)(yong)(yong)(yong)(yong)(yong)栓釘與鋼(gang)梁(liang)(liang)穿透熔(rong)焊(han)；樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)間(jian)用(yong)(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)(yong)夾緊鉗咬合壓孔連接；堵頭(tou)用(yong)(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)(yong)鍍鋅(xin)堵頭(tou)板(ban)(ban)(ban)與樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)及鋼(gang)梁(liang)(liang)點(dian)(dian)焊(han)。如果是帶弧形區(qu)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)異型(xing)裁切(qie)采用(yong)(yong)(yong)(yong)(yong)(yong)等離子(zi)切(qie)割(ge)機(ji)切(qie)割(ge)，其切(qie)口光滑，表面(mian)鍍鋅(xin)層(ceng)完整(zheng)。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)焊(han)接采用(yong)(yong)(yong)(yong)(yong)(yong)手工(gong)電弧點(dian)(dian)焊(han)，焊(han)條為Ｅ4303，直(zhi)徑3.2mm，熔(rong)透焊(han)接點(dian)(dian)為16mm.原設計(ji)焊(han)點(dian)(dian)間(jian)距305mm，后將焊(han)點(dian)(dian)增加(jia)1倍，以確保操作(zuo)人(ren)員行走時樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)不(bu)變形，混凝土澆筑(zhu)時樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)端頭(tou)不(bu)漏漿。當(dang)樓(lou)(lou)(lou)面(mian)層(ceng)結(jie)構(gou)(gou)標高變化(hua)不(bu)一致時，采取加(jia)焊(han)型(xing)鋼(gang)措施(shi)，使水(shui)平結(jie)構(gou)(gou)呈(cheng)臺階過渡，當(dang)降低標高時工(gong)字(zi)梁(liang)(liang)腹板(ban)(ban)(ban)加(jia)焊(han)角鋼(gang)；抬升(sheng)標高時工(gong)字(zi)梁(liang)(liang)翼緣加(jia)焊(han)槽(cao)鋼(gang)。  

樓承(cheng)板的(de)特點 

1：適應主體鋼結構快(kuai)速施工的(de)(de)要求，能(neng)夠(gou)在(zai)短時(shi)間內提供堅定的(de)(de)作業平臺，并可采用多個樓層鋪設壓型鋼板(ban)，分(fen)層澆筑(zhu)混凝(ning)土板(ban)的(de)(de)流(liu)水施工。 

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

3：壓型板(ban)表面壓紋使(shi)樓(lou)承(cheng)板(ban)與混凝土之間產生最大的(de)結合力，使(shi)二者形成整體(ti)，配(pei)以加勁肋，使(shi)樓(lou)承(cheng)板(ban)系統具有(you)高強(qiang)承(cheng)載力。 

4：在懸臂條(tiao)件下，樓承板僅(jin)作(zuo)為(wei)永久性(xing)模(mo)板。懸挑的長度(du)可根據樓承板的截(jie)面特(te)性(xing)來定。為(wei)了(le)防止懸挑板的開裂，需在支座處依(yi)結構(gou)工程(cheng)師的設計配上負筋。 

5：本公司樓承板已通過(guo)國(guo)家固(gu)定滅火系統及(ji)耐(nai)火構件質量檢測中心的耐(nai)火極(ji)限檢測，作為(wei)組合(he)樓承板無需(xu)防火噴(pen)涂，因此大大降低了(le)工程造(zao)價。
