熱鍍鋅批發樓承板適應主體鋼結構快速施工的要求，能夠在短時間內提供堅定的作業平臺，并可采用多個樓層鋪設壓型鋼板，分層澆筑混凝土板的流水施工。資陽熱鍍鋅在(zai)使(shi)(shi)用階段(duan)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)作為混(hun)(hun)凝(ning)土樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)受(shou)拉鋼筋，也(ye)提(ti)高了樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)剛(gang)度(du)，節省了鋼筋和混(hun)(hun)凝(ning)土的(de)(de)(de)用量。樓(lou)(lou)承(cheng)板(ban)(ban)(ban)上面(mian)可以鋪設(she)(she)保溫，隔(ge)音，隔(ge)熱，隔(ge)振(zhen)等材(cai)料(liao)。樓(lou)(lou)面(mian)性(xing)(xing)能充分發揮鋼的(de)(de)(de)良(liang)好(hao)的(de)(de)(de)抗(kang)拉強度(du)和延性(xing)(xing)及混(hun)(hun)凝(ning)土優良(liang)的(de)(de)(de)抗(kang)壓強度(du)和較大的(de)(de)(de)剛(gang)度(du)。壓型板(ban)(ban)(ban)表(biao)面(mian)壓紋(wen)使(shi)(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)與(yu)混(hun)(hun)凝(ning)土之間產(chan)生大的(de)(de)(de)結合力(li)，使(shi)(shi)二(er)者形成整體(ti)，配以加勁肋，使(shi)(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)系統(tong)具有(you)高強承(cheng)載(zai)力(li)。在(zai)懸(xuan)臂條件下，樓(lou)(lou)承(cheng)板(ban)(ban)(ban)僅作為性(xing)(xing)模板(ban)(ban)(ban)。懸(xuan)挑的(de)(de)(de)長度(du)可根據(ju)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)(de)截面(mian)特性(xing)(xing)來定(ding)。為了防止懸(xuan)挑板(ban)(ban)(ban)的(de)(de)(de)開裂，需在(zai)支座處依結構工程(cheng)師的(de)(de)(de)設(she)(she)計配上負筋。

鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼(gang)(gang)的鋅(xin)(xin)(xin)層(ceng)特性(xing) 電鍍(du)鋅(xin)(xin)(xin)層(ceng)是(shi)不能形成鋅(xin)(xin)(xin)花(hua)(hua)的，熱(re)鍍(du)鋅(xin)(xin)(xin)層(ceng)則有鋅(xin)(xin)(xin)花(hua)(hua)，其形成過程如(ru)下：當(dang)鍍(du)鋅(xin)(xin)(xin)帶(dai)從鋅(xin)(xin)(xin)鍋(guo)(guo)出來(lai)后，經(jing)氣刀的噴吹，大(da)(da)量(liang)鋅(xin)(xin)(xin)液被吹回鋅(xin)(xin)(xin)鍋(guo)(guo)，這時帶(dai)鋼(gang)(gang)表面還有純(chun)鋅(xin)(xin)(xin)層(ceng)，呈液 態附在(zai)(zai)鋼(gang)(gang)板(ban)表面，在(zai)(zai)鋼(gang)(gang)板(ban)表面形成大(da)(da)量(liang)結晶(jing)核，隨(sui)著(zhu)鋼(gang)(gang)板(ban)上升冷卻，使結晶(jing)核慢(man)慢(man)長(chang)成鋅(xin)(xin)(xin)花(hua)(hua)。冷卻速(su)度越(yue)(yue)快鋅(xin)(xin)(xin)花(hua)(hua)越(yue)(yue)小(xiao)，冷卻速(su)度越(yue)(yue)慢(man)鋅(xin)(xin)(xin)花(hua)(hua)越(yue)(yue)大(da)(da)。熱(re)鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼(gang)(gang)在(zai)(zai)我國市場一直是(shi)緊缺品種。從20世(shi)紀90年(nian)(nian)代中期(qi)以來(lai)，每年(nian)(nian)都要從國外進口80-100萬t左右(you)。隨(sui)著(zhu)國內經(jing)濟的發展，尤其是(shi)汽(qi)車、家電及建筑業的發展，對鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼(gang)(gang)的需求量(liang)也大(da)(da)大(da)(da)增加。

鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)是(shi)為防(fang)止(zhi)鋼(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)遭(zao)受(shou)腐蝕，延長其使用(yong)壽命，在(zai)鋼(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)涂以一層金屬鋅(xin)(xin)(xin)(xin)，這(zhe)種(zhong)(zhong)(zhong)涂鋅(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。按生產及加工方法(fa)可分為以下(xia)幾類：熱浸(jin)鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。將薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔 微(wei)商貨源解的(de)鋅(xin)(xin)(xin)(xin)槽(cao)中(zhong)，使其表(biao)面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)(ban)。目(mu)前主要采(cai)用(yong)連續鍍(du)鋅(xin)(xin)(xin)(xin)工藝生產，即(ji)(ji)把成卷的(de)鋼(gang)板(ban)(ban)(ban)(ban)連續浸(jin)在(zai)熔解有鋅(xin)(xin)(xin)(xin)的(de)鍍(du)槽(cao)中(zhong)制成鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)；合金化鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。這(zhe)種(zhong)(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)也是(shi)用(yong)熱浸(jin)法(fa)制造，但(dan)在(zai)出槽(cao)后(hou)，立即(ji)(ji)把它(ta)加熱到５００℃左右，使其生成鋅(xin)(xin)(xin)(xin)和鐵的(de)合金被膜。這(zhe)種(zhong)(zhong)(zhong)鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具有良好的(de)涂料的(de)密著性和焊接性。

堆(dui)(dui)積(ji)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)的(de)地坪應(ying)(ying)基本平(ping)坦(tan)，鋼筋桁架樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)堆(dui)(dui)積(ji)不(bu)宜過(guo)高，每(mei)(mei)堆(dui)(dui)不(bu)超越60張。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)運至現場，需妥善保護，不(bu)得(de)有任何損壞和污(wu)染(ran)，特別(bie)不(bu)得(de)感染(ran)油(you)污(wu)。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)應(ying)(ying)根據排版圖(tu)預(yu)先切開、編號。起吊(diao)前，每(mei)(mei)捆(kun)要有兩(liang)條鋼絲繩，分別(bie)捆(kun)于兩(liang)頭(tou)四分之一(yi)鋼板(ban)長度處，采用(yong)專用(yong)吊(diao)具(ju)吊(diao)起。應(ying)(ying)先行試吊(diao)，檢查(cha)重心是否穩(wen)定，鋼索是否會(hui)滑(hua)動，待(dai)牢靠(kao)(kao)，無慮時方可吊(diao)起。起吊(diao)時，應(ying)(ying)從下往上(shang)樓(lou)(lou)(lou)層(ceng)(ceng)次(ci)序吊(diao)料為原則，避免因先行吊(diao)放(fang)上(shang)層(ceng)(ceng)資料后(hou)，阻止下面樓(lou)(lou)(lou)層(ceng)(ceng)的(de)吊(diao)放(fang)作(zuo)業。整疊(die)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)放(fang)梁面時，應(ying)(ying)考慮梁的(de)承(cheng)(cheng)載能力，避免因集中載荷過(guo)大，造成(cheng)梁的(de)變形。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)吊(diao)至樓(lou)(lou)(lou)層(ceng)(ceng)，暫時不(bu)鋪設時，應(ying)(ying)作(zuo)牢靠(kao)(kao)固定，避免飛落和滑(hua)落傷人。
