堆(dui)積(ji)樓承(cheng)(cheng)板的地坪應(ying)(ying)基本平坦，鋼(gang)筋(jin)桁架樓承(cheng)(cheng)板堆(dui)積(ji)不(bu)(bu)宜過高，每堆(dui)不(bu)(bu)超越(yue)60張(zhang)。樓承(cheng)(cheng)板運至(zhi)現(xian)場(chang)，需妥善保護，不(bu)(bu)得有任(ren)何損壞和污染，特別不(bu)(bu)得感染油(you)污。樓承(cheng)(cheng)板應(ying)(ying)根據排版圖預先切(qie)開、編(bian)號。起吊(diao)(diao)(diao)前，每捆(kun)(kun)要有兩條鋼(gang)絲繩，分別捆(kun)(kun)于(yu)兩頭四分之一鋼(gang)板長度處(chu)，采用專用吊(diao)(diao)(diao)具吊(diao)(diao)(diao)起。應(ying)(ying)先行(xing)試(shi)吊(diao)(diao)(diao)，檢查重心是否(fou)穩定，鋼(gang)索是否(fou)會滑(hua)動，待牢靠，無慮時(shi)方(fang)可(ke)吊(diao)(diao)(diao)起。起吊(diao)(diao)(diao)時(shi)，應(ying)(ying)從下(xia)往(wang)上(shang)樓層次序吊(diao)(diao)(diao)料為(wei)原(yuan)則，避免因(yin)先行(xing)吊(diao)(diao)(diao)放(fang)上(shang)層資料后，阻止下(xia)面(mian)樓層的吊(diao)(diao)(diao)放(fang)作(zuo)業。整疊樓承(cheng)(cheng)板放(fang)梁面(mian)時(shi)，應(ying)(ying)考慮梁的承(cheng)(cheng)載能(neng)力(li)，避免因(yin)集中載荷過大，造成梁的變形。樓承(cheng)(cheng)板吊(diao)(diao)(diao)至(zhi)樓層，暫時(shi)不(bu)(bu)鋪設時(shi)，應(ying)(ying)作(zuo)牢靠固定，避免飛落和滑(hua)落傷人(ren)。

彩涂卷廠家鍍鋅帶鋼的鋅層特性 電鍍鋅層是不能形成鋅花的，熱鍍鋅層則有鋅花，其形成過程如下：當鍍鋅帶從鋅鍋出來后，經氣刀的噴吹，大量鋅液被吹回鋅鍋，這時帶鋼表面還有純鋅層，呈液 態附在鋼板表面，在鋼板表面形成大量結晶核，隨著鋼板上升冷卻，使結晶核慢慢長成鋅花。彭水酒鋼彩涂卷冷卻(que)速度越(yue)快鋅(xin)(xin)花越(yue)小，冷卻(que)速度越(yue)慢鋅(xin)(xin)花越(yue)大(da)。熱鍍鋅(xin)(xin)帶鋼在(zai)我國市場(chang)一直(zhi)是(shi)緊缺品種。從20世紀90年代中期(qi)以來，每(mei)年都要從國外進口80-100萬t左右(you)。隨著國內(nei)經濟的發(fa)展(zhan)，尤其(qi)是(shi)汽(qi)車、家電及建筑業的發(fa)展(zhan)，對(dui)鍍鋅(xin)(xin)帶鋼的需求量也大(da)大(da)增加。
