樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)習慣主體(ti)鋼(gang)結構(gou)(gou)快速(su)施工(gong)(gong)的(de)要求(qiu)，能夠在短時間內提(ti)供堅定的(de)作(zuo)業渠道，并可采用(yong)多個樓(lou)層鋪設壓(ya)(ya)型(xing)鋼(gang)板(ban)(ban)，分(fen)層澆筑混(hun)凝(ning)土(tu)板(ban)(ban)的(de)流水施工(gong)(gong)。在運用(yong)階段樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)作(zuo)為(wei)混(hun)凝(ning)土(tu)樓(lou)板(ban)(ban)的(de)受(shou)拉(la)鋼(gang)筋(jin)，也(ye)提(ti)高(gao)了樓(lou)板(ban)(ban)的(de)剛度(du)(du)，節省了鋼(gang)筋(jin)和混(hun)凝(ning)土(tu)的(de)用(yong)量。樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)上面(mian)(mian)能夠鋪設保溫，隔(ge)音，隔(ge)熱，隔(ge)振等資(zi)料(liao)。改進(jin)樓(lou)面(mian)(mian)性能充分(fen)發(fa)揮鋼(gang)的(de)杰出的(de)抗拉(la)強(qiang)(qiang)度(du)(du)和延性及混(hun)凝(ning)土(tu)優良的(de)抗壓(ya)(ya)強(qiang)(qiang)度(du)(du)和較大(da)的(de)剛度(du)(du)。壓(ya)(ya)型(xing)板(ban)(ban)表面(mian)(mian)壓(ya)(ya)紋使(shi)樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)與混(hun)凝(ning)土(tu)之間產生(sheng)大(da)的(de)結合力(li)，使(shi)二者形成整體(ti)，配以加勁肋，使(shi)樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)體(ti)系具(ju)有(you)高(gao)強(qiang)(qiang)承(cheng)(cheng)(cheng)(cheng)載力(li)。在懸(xuan)臂條件(jian)下，樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)僅作(zuo)為(wei)性模(mo)板(ban)(ban)。懸(xuan)挑的(de)長(chang)度(du)(du)可根據樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)的(de)截面(mian)(mian)特性來定。為(wei)了避(bi)免(mian)懸(xuan)挑板(ban)(ban)的(de)開裂，需(xu)在支座處依結構(gou)(gou)工(gong)(gong)程(cheng)師的(de)規劃配上負筋(jin)。本(ben)公司樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)已(yi)通(tong)過(guo)國家固定救活體(ti)系及耐火構(gou)(gou)件(jian)質量檢(jian)測中心(xin)的(de)耐火檢(jian)測，作(zuo)為(wei)組合樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)無需(xu)防火噴涂，因而大(da)大(da)降低了工(gong)(gong)程(cheng)造價。

攀鋼冷軋卷堆積樓承板的地坪應基本平坦，鋼筋桁架樓承板堆積不宜過高，每堆不超越60張。新疆冷軋卷批發樓(lou)(lou)承(cheng)板(ban)運至現場(chang)，需妥善(shan)保(bao)護，不(bu)(bu)得有任何損壞和(he)污染(ran)，特別不(bu)(bu)得感(gan)染(ran)油污。樓(lou)(lou)承(cheng)板(ban)應(ying)根據排版圖預先(xian)切開、編(bian)號。起吊(diao)(diao)前，每捆要有兩條鋼絲繩，分別捆于兩頭四分之(zhi)一鋼板(ban)長度處(chu)，采(cai)用專用吊(diao)(diao)具(ju)吊(diao)(diao)起。應(ying)先(xian)行(xing)試吊(diao)(diao)，檢查重心是否穩定(ding)，鋼索是否會滑動，待牢靠，無慮時(shi)(shi)方可吊(diao)(diao)起。起吊(diao)(diao)時(shi)(shi)，應(ying)從下往上(shang)樓(lou)(lou)層次(ci)序吊(diao)(diao)料為原則，避免因(yin)先(xian)行(xing)吊(diao)(diao)放上(shang)層資(zi)料后，阻止(zhi)下面樓(lou)(lou)層的(de)吊(diao)(diao)放作業。整疊樓(lou)(lou)承(cheng)板(ban)放梁面時(shi)(shi)，應(ying)考慮梁的(de)承(cheng)載(zai)能力，避免因(yin)集中載(zai)荷過(guo)大(da)，造成梁的(de)變(bian)形(xing)。樓(lou)(lou)承(cheng)板(ban)吊(diao)(diao)至樓(lou)(lou)層，暫時(shi)(shi)不(bu)(bu)鋪設(she)時(shi)(shi)，應(ying)作牢靠固定(ding)，避免飛落和(he)滑落傷人。

樓(lou)(lou)承板(ban)(ban)(ban)組合板(ban)(ban)(ban)是一種十分合理的(de)(de)(de)結構方(fang)(fang)式，它能(neng)夠(gou)(gou)按其(qi)各(ge)組成(cheng)部件所處的(de)(de)(de)方(fang)(fang)位和(he)特色，充分發(fa)揮鋼材抗拉和(he)混(hun)凝(ning)土抗壓功能(neng)好(hao)的(de)(de)(de)長處，并(bing)具(ju)(ju)有(you)杰出的(de)(de)(de)抗震功能(neng)、施工功能(neng)。這種結構現(xian)在被廣(guang)泛運(yun)用(yong)(yong)于國(guo)內外修建中(zhong)，但在國(guo)內大(da)都將樓(lou)(lou)承板(ban)(ban)(ban)當作(zuo)模(mo)板(ban)(ban)(ban)運(yun)用(yong)(yong)，而沒(mei)有(you)充分發(fa)揮樓(lou)(lou)承板(ban)(ban)(ban)的(de)(de)(de)效(xiao)果(guo)。 與一般(ban)鋼筋(jin)混(hun)凝(ning)土樓(lou)(lou)板(ban)(ban)(ban)比較，樓(lou)(lou)承板(ban)(ban)(ban)組合樓(lou)(lou)板(ban)(ban)(ban)具(ju)(ju)備以下長處：樓(lou)(lou)承板(ban)(ban)(ban)能(neng)夠(gou)(gou)作(zuo)為現(xian)澆混(hun)凝(ning)土的(de)(de)(de)模(mo)板(ban)(ban)(ban)。這樣就省(sheng)掉(diao)了(le)施工中(zhong)裝(zhuang)置和(he)撤除模(mo)板(ban)(ban)(ban)等工序，然(ran)后(hou)(hou)節約(yue)了(le)時(shi)刻和(he)勞動力;當樓(lou)(lou)承板(ban)(ban)(ban)裝(zhuang)置好(hao)今后(hou)(hou)將能(neng)夠(gou)(gou)作(zuo)為施工平臺運(yun)用(yong)(yong)。

熱鍍(du)(du)鋅生產(chan)發展(zhan)一(yi)直(zhi)處于滯(zhi)后狀態。20世(shi)紀(ji)50年代(dai)到60年代(dai)陸續建(jian)(jian)成了13條單張鋼板熔劑(ji)法熱鍍(du)(du)鋅機組(zu)，能(neng)力為10萬t/a，但因(yin)產(chan)量低、成本高、質量差、污(wu)染環境、經濟(ji)效益差等(deng)缺陷已(yi)先后停、轉產(chan)。從(cong)20世(shi)紀(ji)70年代(dai)末，我國(guo)(guo)才開始建(jian)(jian)造大(da)型寬(kuan)帶熱鍍(du)(du)鋅機組(zu)。熱鍍(du)(du)鋅帶鋼在我國(guo)(guo)市場(chang)一(yi)直(zhi)是緊缺品種。從(cong)20世(shi)紀(ji)90年代(dai)中期以來，每年都要(yao)從(cong)國(guo)(guo)外進口(kou)80-100萬t左(zuo)右。隨著(zhu)國(guo)(guo)內經濟(ji)的(de)(de)發展(zhan)，尤其是汽(qi)車(che)、家電及建(jian)(jian)筑(zhu)業的(de)(de)發展(zhan)，對鍍(du)(du)鋅帶鋼的(de)(de)需求量也大(da)大(da)增(zeng)加(jia)。
