樓(lou)承板(ban)(ban)(ban)(ban)組(zu)合板(ban)(ban)(ban)(ban)是(shi)一種十分合理的結構(gou)(gou)方(fang)式，它能(neng)夠(gou)(gou)按其各組(zu)成部件所處的方(fang)位和(he)特色，充分發(fa)揮鋼(gang)材抗拉和(he)混(hun)凝(ning)土(tu)抗壓功(gong)能(neng)好(hao)(hao)的長處，并具有(you)(you)杰(jie)出的抗震功(gong)能(neng)、施工(gong)功(gong)能(neng)。這種結構(gou)(gou)現在(zai)被廣(guang)泛運(yun)用(yong)于國內(nei)外修(xiu)建中(zhong)，但在(zai)國內(nei)大(da)都(dou)將(jiang)(jiang)樓(lou)承板(ban)(ban)(ban)(ban)當作(zuo)模板(ban)(ban)(ban)(ban)運(yun)用(yong)，而(er)沒有(you)(you)充分發(fa)揮樓(lou)承板(ban)(ban)(ban)(ban)的效果。 與一般鋼(gang)筋混(hun)凝(ning)土(tu)樓(lou)板(ban)(ban)(ban)(ban)比較，樓(lou)承板(ban)(ban)(ban)(ban)組(zu)合樓(lou)板(ban)(ban)(ban)(ban)具備以下(xia)長處：樓(lou)承板(ban)(ban)(ban)(ban)能(neng)夠(gou)(gou)作(zuo)為現澆混(hun)凝(ning)土(tu)的模板(ban)(ban)(ban)(ban)。這樣就省掉了(le)施工(gong)中(zhong)裝置(zhi)和(he)撤除模板(ban)(ban)(ban)(ban)等(deng)工(gong)序，然后節(jie)約了(le)時刻和(he)勞動力;當樓(lou)承板(ban)(ban)(ban)(ban)裝置(zhi)好(hao)(hao)今后將(jiang)(jiang)能(neng)夠(gou)(gou)作(zuo)為施工(gong)平臺運(yun)用(yong)。

彩涂卷價格鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。蘇州彩涂卷電鍍鋅(xin)成(cheng)本(ben)低，表面不(bu)是很光滑(hua)，其本(ben)身的(de)(de)(de)耐(nai)腐蝕性比熱鍍鋅(xin)管(guan)(guan)相差很多。提起鍍鋅(xin)管(guan)(guan)，可能沒接觸過建材的(de)(de)(de)朋友并不(bu)了解。從1935年建立一(yi)條連續涂層鋼板(ban)線開始，彩(cai)(cai)涂板(ban)得到了廣泛應用，目前彩(cai)(cai)涂板(ban)的(de)(de)(de)品種繁多，大約超(chao)過600種，彩(cai)(cai)涂板(ban)兼(jian)有(you)機(ji)聚合(he)物與(yu)鋼板(ban)兩者的(de)(de)(de)優點，既有(you)有(you)機(ji)聚合(he)物的(de)(de)(de)良好(hao)著(zhu)色性、成(cheng)型性、耐(nai)蝕性、裝飾(shi)性、又(you)有(you)鋼板(ban)的(de)(de)(de)高強(qiang)度和易(yi)加工性，能很容易(yi)地進行沖(chong)壓裁剪(jian)、彎曲、深沖(chong)等加工。

實(shi)現(xian)了機械(xie)化生(sheng)產(chan)(chan)，有利于鋼(gang)筋排列間距均勻、混凝土保(bao)護層(ceng)厚度(du)一致，提高了樓板的(de)(de)施(shi)(shi)工(gong)質量。裝(zhuang)(zhuang)配(pei)式鋼(gang)筋桁架樓承板可顯著減少現(xian)場鋼(gang)筋綁(bang)扎工(gong)程量，加(jia)快(kuai)施(shi)(shi)工(gong)進度(du)，增加(jia)施(shi)(shi)工(gong)保(bao)證，實(shi)現(xian)文明施(shi)(shi)工(gong)。裝(zhuang)(zhuang)配(pei)式模板和連接件拆裝(zhuang)(zhuang)方(fang)便(bian)，可多次(ci)重復利用，節約鋼(gang)材，符合國(guo)家節能(neng)(neng)環保(bao)的(de)(de)要(yao)求(qiu)。鋼(gang)構自主研(yan)發的(de)(de)產(chan)(chan)品配(pei)套自動化生(sheng)產(chan)(chan)設備，大(da)大(da)提高了勞動生(sheng)產(chan)(chan)率(lv)，有效降低(di)了產(chan)(chan)品成本，并編制了產(chan)(chan)品生(sheng)產(chan)(chan)企(qi)業標準、設計手冊(ce)和節點構造圖集(ji)以(yi)及施(shi)(shi)工(gong)手冊(ce)。并經過多項(xiang)工(gong)程應(ying)用，各(ge)項(xiang)性能(neng)(neng)可以(yi)滿足現(xian)澆鋼(gang)筋混凝土樓板承載(zai)力和變形的(de)(de)要(yao)求(qiu)。

樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)習慣主(zhu)體(ti)(ti)鋼結構快速(su)施(shi)工的(de)要(yao)求，能(neng)(neng)夠(gou)(gou)在(zai)短時間(jian)內提(ti)供(gong)堅定的(de)作業渠道，并(bing)可采用(yong)多(duo)個樓層鋪(pu)設(she)壓型鋼板(ban)(ban)(ban)，分層澆筑混凝(ning)(ning)土板(ban)(ban)(ban)的(de)流水施(shi)工。在(zai)運用(yong)階段樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)作為(wei)(wei)混凝(ning)(ning)土樓板(ban)(ban)(ban)的(de)受拉鋼筋(jin)(jin)，也(ye)提(ti)高了(le)樓板(ban)(ban)(ban)的(de)剛(gang)度，節省了(le)鋼筋(jin)(jin)和混凝(ning)(ning)土的(de)用(yong)量。樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)上(shang)面能(neng)(neng)夠(gou)(gou)鋪(pu)設(she)保(bao)溫，隔(ge)音，隔(ge)熱，隔(ge)振等資料(liao)。改(gai)進樓面性能(neng)(neng)充分發(fa)揮鋼的(de)杰出的(de)抗拉強(qiang)度和延性及(ji)混凝(ning)(ning)土優良的(de)抗壓強(qiang)度和較大(da)的(de)剛(gang)度。壓型板(ban)(ban)(ban)表面壓紋使(shi)樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)與混凝(ning)(ning)土之(zhi)間(jian)產生(sheng)大(da)的(de)結合力(li)，使(shi)二(er)者形成整體(ti)(ti)，配以加勁(jing)肋，使(shi)樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)體(ti)(ti)系具(ju)有高強(qiang)承(cheng)(cheng)(cheng)(cheng)載力(li)。在(zai)懸(xuan)臂條件下，樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)僅作為(wei)(wei)性模(mo)板(ban)(ban)(ban)。懸(xuan)挑(tiao)(tiao)的(de)長度可根據樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)的(de)截面特(te)性來定。為(wei)(wei)了(le)避(bi)免懸(xuan)挑(tiao)(tiao)板(ban)(ban)(ban)的(de)開(kai)裂，需(xu)在(zai)支座處依結構工程師的(de)規劃配上(shang)負筋(jin)(jin)。本公司樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)已通過國(guo)家固定救活體(ti)(ti)系及(ji)耐火(huo)(huo)構件質量檢測(ce)中心的(de)耐火(huo)(huo)檢測(ce)，作為(wei)(wei)組(zu)合樓承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)無需(xu)防火(huo)(huo)噴涂(tu)，因而大(da)大(da)降低了(le)工程造價。

熱(re)鍍(du)(du)鋅(xin)(xin)板(ban)(ban)和電(dian)鍍(du)(du)鋅(xin)(xin)板(ban)(ban)在鍍(du)(du)鋅(xin)(xin)量上有很大的(de)(de)差別(bie)，就像山東彩涂卷）。熱(re)鍍(du)(du)鋅(xin)(xin)的(de)(de)鍍(du)(du)鋅(xin)(xin)量不(bu)可(ke)能太小，一(yi)般(ban)(ban)較小為雙(shuang)面50～60g／m2，較大可(ke)達(da)600g／m2。電(dian)鍍(du)(du)鋅(xin)(xin)板(ban)(ban)的(de)(de)鍍(du)(du)鋅(xin)(xin)層可(ke)以很薄，較小達(da)15g／m2，但要求鍍(du)(du)層較厚的(de)(de)話則生產(chan)線速(su)度很慢，不(bu)適(shi)應現(xian)代化(hua)機組的(de)(de)工(gong)(gong)藝特(te)點，一(yi)般(ban)(ban)較大為lO0g／m2左右。正因為如(ru)此，電(dian)鍍(du)(du)鋅(xin)(xin)板(ban)(ban)的(de)(de)生產(chan)受到(dao)很大的(de)(de)限制。工(gong)(gong)一(yi)般(ban)(ban)電(dian)鍍(du)(du)鋅(xin)(xin)比較多，適(shi)用(yong)于小部件；熱(re)鍍(du)(du)鋅(xin)(xin)一(yi)般(ban)(ban)用(yong)于電(dian)力(li)設(she)(she)備和構(gou)件，適(shi)用(yong)于大的(de)(de)部件和設(she)(she)備。當然(ran)他們的(de)(de)價格也(ye)相(xiang)對便宜一(yi)些。建設(she)(she)部已正式下文，淘汰技術(shu)落后的(de)(de)冷(leng)鍍(du)(du)鋅(xin)(xin)管(guan)，不(bu)準用(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)管(guan)作(zuo)水(shui)、煤(mei)氣管(guan)。
