河北鍍鋅鋼樓承板鋼結構柱網間距一般5~9.0m×8~15m，次梁間距3m，而樓承板下料長度為4.97~8.97m，運輸與安裝均較困難，尤其是帶由圓弧區垂直吊裝樓承板，由上而下在次梁狹間穿套比較困難，且打亂了次梁焊接正常工序。控制下料長度為3～6m，則可避免垂直運輸時在次梁間無法吊運的問題。 鍍鋅鋼價格樓承(cheng)(cheng)板(ban)(ban)(ban)吊(diao)運時采(cai)用專用軟吊(diao)索。每次吊(diao)裝時應(ying)(ying)(ying)(ying)檢(jian)查軟吊(diao)索是否有撕裂、割斷(duan)現象(xiang)。樓承(cheng)(cheng)板(ban)(ban)(ban)擱置在鋼梁上時應(ying)(ying)(ying)(ying)防止探頭。鋪料時操(cao)作人員應(ying)(ying)(ying)(ying)系帶，并保(bao)證(zheng)邊(bian)(bian)鋪設邊(bian)(bian)固定(ding)在周邊(bian)(bian)繩上。 焊(han)(han)接(jie)采(cai)用熔透(tou)點焊(han)(han)連接(jie)，施(shi)焊(han)(han)前應(ying)(ying)(ying)(ying)準備邊(bian)(bian)角料引弧試焊(han)(han)，調整施(shi)焊(han)(han)電(dian)流.因樓承(cheng)(cheng)板(ban)(ban)(ban)底部無水(shui)平模板(ban)(ban)(ban)及垂(chui)直支撐，澆筑混凝土時布(bu)料不宜(yi)太集中，采(cai)用平板(ban)(ban)(ban)振搗器及時分攤(tan)振搗。

樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)組合板(ban)(ban)(ban)(ban)(ban)是一種(zhong)十分合理的(de)(de)(de)結(jie)構方(fang)式(shi)，它(ta)能(neng)(neng)夠按其各組成部件所處的(de)(de)(de)方(fang)位和特色，充(chong)分發(fa)揮(hui)鋼(gang)材抗拉(la)和混凝土抗壓功能(neng)(neng)好(hao)的(de)(de)(de)長處，并具有杰出的(de)(de)(de)抗震功能(neng)(neng)、施工(gong)功能(neng)(neng)。這種(zhong)結(jie)構現(xian)在(zai)被廣泛運用于國內(nei)外修建中(zhong)，但在(zai)國內(nei)大都將樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)當作(zuo)模(mo)板(ban)(ban)(ban)(ban)(ban)運用，而沒有充(chong)分發(fa)揮(hui)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)效果。 與一般(ban)鋼(gang)筋混凝土樓(lou)板(ban)(ban)(ban)(ban)(ban)比較，樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)組合樓(lou)板(ban)(ban)(ban)(ban)(ban)具備以下長處：樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)能(neng)(neng)夠作(zuo)為現(xian)澆混凝土的(de)(de)(de)模(mo)板(ban)(ban)(ban)(ban)(ban)。這樣(yang)就省掉了(le)施工(gong)中(zhong)裝置和撤除模(mo)板(ban)(ban)(ban)(ban)(ban)等(deng)工(gong)序，然(ran)后(hou)節約(yue)了(le)時刻和勞(lao)動力;當樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)裝置好(hao)今后(hou)將能(neng)(neng)夠作(zuo)為施工(gong)平臺運用。

鍍(du)(du)鋅(xin)鋼(gang)板的(de)表面鍍(du)(du)鋅(xin)主要采(cai)(cai)用的(de)方(fang)法是熱(re)(re)鍍(du)(du)鋅(xin)。熱(re)(re)鍍(du)(du)鋅(xin)是由較古老的(de)熱(re)(re)鍍(du)(du)方(fang)法發(fa)展而(er)來(lai)的(de)，自(zi)從(cong)1836年法國把熱(re)(re)鍍(du)(du)鋅(xin)應用于(yu)工業以(yi)來(lai)，已經有一百七十(shi)(shi)年的(de)歷(li)史(shi)了。然而(er)，熱(re)(re)鍍(du)(du)鋅(xin)工業是近(jin)(jin)三十(shi)(shi)年來(lai)伴隨冷(leng)軋帶鋼(gang)的(de)飛速發(fa)展而(er)得到了大規(gui)模發(fa)展。鍍(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)有氰(qing)化(hua)物(wu)鍍(du)(du)液(ye)(ye)(ye)和無(wu)(wu)氰(qing)鍍(du)(du)液(ye)(ye)(ye)兩類。氰(qing)化(hua)物(wu)鍍(du)(du)液(ye)(ye)(ye)中分微(wei)氰(qing)、低氰(qing)、中氰(qing)、和高氰(qing)幾(ji)類。無(wu)(wu)氰(qing)鍍(du)(du)液(ye)(ye)(ye)有堿性鋅(xin)酸(suan)鹽鍍(du)(du)液(ye)(ye)(ye)、銨鹽鍍(du)(du)液(ye)(ye)(ye)、硫酸(suan)鹽鍍(du)(du)液(ye)(ye)(ye)及無(wu)(wu)氨(an)氯化(hua)物(wu)鍍(du)(du)液(ye)(ye)(ye)等(deng)。氰(qing)化(hua)鍍(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)均(jun)鍍(du)(du)能力好，得到的(de)鍍(du)(du)層光滑細致(zhi)，在(zai)生產中被長(chang)期采(cai)(cai)用。但由于(yu)氰(qing)化(hua)物(wu)劇毒，對環境污染嚴重，近(jin)(jin)年來(lai)已趨向于(yu)采(cai)(cai)用低氰(qing)、微(wei)氰(qing)、無(wu)(wu)氰(qing)鍍(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)。
