近期好多客戶咨詢通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)使(shi)(shi)用(yong)壽命的(de)(de)(de)問題，想(xiang)了(le)解通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)能使(shi)(shi)用(yong)多少年，就必須知道通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)的(de)(de)(de)結(jie)構(gou)組成(cheng)。通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)是(shi)安裝(zhuang)于鋼結(jie)構(gou)廠房(fang)屋頂的(de)(de)(de)一種通(tong)風(feng)設(she)備(bei)，具(ju)有(you)通(tong)風(feng)換氣(qi)和(he)采光(guang)排(pai)煙的(de)(de)(de)作用(yong)。其結(jie)構(gou)組成(cheng)可分為：天(tian)窗(chuang)骨架-牽(qian)引拉桿(gan)-啟閉筏(fa)板(ban)-傳動(dong)系(xi)統-筏(fa)板(ban)中軸(zhou)-牽(qian)引構(gou)件-擋(dang)雨板(ban)-集水槽(cao)-脊瓦(wa)-泛(fan)水板(ban)-側封板(ban)-端頭(tou)泛(fan)水板(ban)-端頭(tou)板(ban)-包角等(deng)。本(ben)文就從通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)的(de)(de)(de)整體結(jie)構(gou)、材質和(he)使(shi)(shi)用(yong)環境(jing)等(deng)幾個方面(mian)來談談通(tong)風(feng)天(tian)窗(chuang)/氣(qi)樓(lou)(lou)的(de)(de)(de)使(shi)(shi)用(yong)年限(xian)。

首先談下通風(feng)天窗/氣樓(lou)的(de)(de)(de)材質(zhi)，（1）天窗骨架和筏(fa)板(ban)(ban)(ban)(ban)骨架、牽引拉桿、筏(fa)板(ban)(ban)(ban)(ban)中軸、傳動軸等可選(xuan)用的(de)(de)(de)材料有冷、熱(re)鍍鋅(xin)(xin)(xin)方(fang)(fang)管(guan)和不(bu)銹(xiu)鋼方(fang)(fang)管(guan)。同(tong)樣(yang)的(de)(de)(de)壁(bi)厚(hou)和使用環(huan)(huan)境條(tiao)(tiao)件(jian)下，金屬(shu)使用年(nian)限為：冷鍍鋅(xin)(xin)(xin)方(fang)(fang)管(guan)＜熱(re)鍍鋅(xin)(xin)(xin)方(fang)(fang)管(guan)＜不(bu)銹(xiu)鋼方(fang)(fang)管(guan)。（2）擋(dang)雨板(ban)(ban)(ban)(ban)一般(ban)選(xuan)用FRP采(cai)光板(ban)(ban)(ban)(ban)或(huo)陽光板(ban)(ban)(ban)(ban)。其使用壽(shou)命(ming)和產品的(de)(de)(de)等級、厚(hou)度或(huo)層數、質(zhi)保期長短(duan)有關。（3）側封板(ban)(ban)(ban)(ban)、脊瓦、泛水(shui)板(ban)(ban)(ban)(ban)、集水(shui)槽(cao)、端(duan)頭板(ban)(ban)(ban)(ban)等一般(ban)選(xuan)用彩鋼板(ban)(ban)(ban)(ban)、鍍鋁鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)或(huo)不(bu)銹(xiu)鋼板(ban)(ban)(ban)(ban)。同(tong)樣(yang)的(de)(de)(de)壁(bi)厚(hou)和使用環(huan)(huan)境條(tiao)(tiao)件(jian)下，使用壽(shou)命(ming)為：彩鋼板(ban)(ban)(ban)(ban)＜鍍鋁鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)＜不(bu)銹(xiu)鋼板(ban)(ban)(ban)(ban)。

再次就是(shi)使(shi)用(yong)環(huan)(huan)境對通(tong)風(feng)天(tian)窗(chuang)(chuang)/氣(qi)(qi)樓的影響，眾所周(zhou)知，高(gao)溫高(gao)濕和腐蝕(shi)性強的環(huan)(huan)境對通(tong)風(feng)天(tian)窗(chuang)(chuang)/氣(qi)(qi)樓壽命的影響是(shi)很大的。一般在工(gong)程立項階段(duan)設計單位就會根據建筑的使(shi)用(yong)性質(zhi)，在選用(yong)通(tong)風(feng)天(tian)窗(chuang)(chuang)/氣(qi)(qi)樓的規格(ge)型號(hao)和材質(zhi)都會綜合考(kao)量(liang)。總體(ti)思路是(shi)建筑整(zheng)體(ti)構(gou)件大于(yu)通(tong)風(feng)天(tian)窗(chuang)(chuang)/氣(qi)(qi)樓的使(shi)用(yong)年限。隨著近些年防(fang)(fang)腐防(fang)(fang)銹技術的進步，以及(ji)在通(tong)風(feng)設備領域的廣泛應(ying)用(yong)，通(tong)風(feng)天(tian)窗(chuang)(chuang)/氣(qi)(qi)樓產品的使(shi)用(yong)壽命整(zheng)體(ti)上了(le)一個臺階。
