懷化攀鋼鍍鋅角鋼要看整個樓板的厚度來考慮挑選是用75波高系列的仍是51波高系列的，沉默有40系列，46系列，60系列，65波高系列。鍍鋅角鋼價格一(yi)般(ban)來說(shuo)波高(gao)(gao)越(yue)(yue)低，承(cheng)載力就越(yue)(yue)低，然(ran)后就是波峰距離(li)越(yue)(yue)大，承(cheng)載力就越(yue)(yue)小，假如整(zheng)(zheng)個樓板(ban)厚度在10公(gong)分(fen)(fen)以內(nei)，好(hao)選用選用波高(gao)(gao)40系列，整(zheng)(zheng)個樓板(ban)厚度在10-13公(gong)分(fen)(fen)以內(nei)，好(hao)選用50波高(gao)(gao)系列，在13公(gong)分(fen)(fen)以上，好(hao)選用75系列。有些人(ren)會問，為什么呀?其實《我(wo)國鋼(gang)筋混(hun)凝(ning)土修建規范》里有個要求，鋼(gang)筋上面的(de)(de)混(hun)泥土保(bao)護(hu)層不能低于2.5cm，就是說(shuo)樓承(cheng)板(ban)自身的(de)(de)波高(gao)(gao)+鋼(gang)筋網的(de)(de)厚度(一(yi)般(ban)2cm)+2.5cm的(de)(de)保(bao)護(hu)層≤樓板(ban)的(de)(de)厚度。

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)組(zu)合板(ban)(ban)(ban)是一(yi)種十分(fen)(fen)(fen)合理(li)的(de)結(jie)(jie)構方(fang)式，它能(neng)(neng)夠按(an)其各組(zu)成(cheng)部(bu)件所(suo)處的(de)方(fang)位和(he)特(te)色，充分(fen)(fen)(fen)發揮鋼材(cai)抗拉(la)和(he)混凝(ning)土(tu)抗壓功能(neng)(neng)好的(de)長處，并(bing)具有杰出的(de)抗震功能(neng)(neng)、施(shi)工(gong)功能(neng)(neng)。這種結(jie)(jie)構現在被(bei)廣泛運(yun)用于國內外(wai)修建中，但(dan)在國內大(da)都將樓(lou)(lou)承(cheng)板(ban)(ban)(ban)當(dang)作(zuo)模(mo)板(ban)(ban)(ban)運(yun)用，而沒有充分(fen)(fen)(fen)發揮樓(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)效果。 與一(yi)般鋼筋混凝(ning)土(tu)樓(lou)(lou)板(ban)(ban)(ban)比較，樓(lou)(lou)承(cheng)板(ban)(ban)(ban)組(zu)合樓(lou)(lou)板(ban)(ban)(ban)具備(bei)以下長處：樓(lou)(lou)承(cheng)板(ban)(ban)(ban)能(neng)(neng)夠作(zuo)為(wei)現澆(jiao)混凝(ning)土(tu)的(de)模(mo)板(ban)(ban)(ban)。這樣就省掉了施(shi)工(gong)中裝置(zhi)和(he)撤除模(mo)板(ban)(ban)(ban)等工(gong)序，然后節約了時(shi)刻和(he)勞動力(li);當(dang)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)裝置(zhi)好今后將能(neng)(neng)夠作(zuo)為(wei)施(shi)工(gong)平臺運(yun)用。

熱鍍(du)鋅(xin)(xin)卷板價格(ge)行(xing)業(ye)統計(ji)數(shu)據(ju)(ju)顯示(shi)，十(shi)一月(yue)國內粗鋼日均產量為兩(liang)百零九萬噸(dun)，環比(bi)下降3.3%，創出(chu)今年(nian)以來水平，但(dan)是當前減(jian)產受到季節性(xing)因素支撐(cheng)，市場對(dui)數(shu)據(ju)(ju)有(you)效(xiao)性(xing)提(ti)出(chu)質疑。鍍(du)鋅(xin)(xin)卷工(gong)業(ye)品而言(yan)，近期陸(lu)續公布(bu)的重要(yao)數(shu)據(ju)(ju)中(zhong)性(xing)偏多。但(dan)值得注(zhu)意的是，同年(nian)十(shi)一月(yue)熱鍍(du)鋅(xin)(xin)卷板價格(ge)工(gong)業(ye)增加(jia)值和投資增速放緩，進(jin)一步(bu)印證了國內總需(xu)求乏力(li)，工(gong)業(ye)復(fu)蘇形勢不容樂觀。加(jia)上未來經濟結(jie)構調整(zheng)等因素，工(gong)業(ye)品價格(ge)反彈高度(du)將(jiang)有(you)限。傳統需(xu)求淡季效(xiao)應還在持續不斷地發酵，冬儲(chu)效(xiao)果不佳。雖然數(shu)據(ju)(ju)顯示(shi)供應壓力(li)開始(shi)減(jian)輕，但(dan)是目前處于(yu)鋼鐵需(xu)求淡季，市場成交(jiao)萎縮，下游(you)采購遲(chi)遲(chi)未能(neng)有(you)效(xiao)跟(gen)進(jin)，市場信心不足，鍍(du)鋅(xin)(xin)鋼板貿易商囤貨現象也不明(ming)顯。
