近期好多(duo)客(ke)戶咨(zi)詢通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)使(shi)用(yong)壽命的問題，想了解通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)能使(shi)用(yong)多(duo)少年，就(jiu)必須知道(dao)通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)的結構(gou)組(zu)成。通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)是安裝于(yu)鋼結構(gou)廠房(fang)屋頂(ding)的一種(zhong)通(tong)(tong)風(feng)設備，具有通(tong)(tong)風(feng)換氣(qi)(qi)和采光排煙的作用(yong)。其結構(gou)組(zu)成可分為：天(tian)窗(chuang)骨(gu)架-牽引(yin)拉(la)桿(gan)-啟閉(bi)筏板(ban)-傳動系(xi)統-筏板(ban)中軸-牽引(yin)構(gou)件(jian)-擋雨板(ban)-集水(shui)槽-脊(ji)瓦-泛水(shui)板(ban)-側封板(ban)-端(duan)頭(tou)泛水(shui)板(ban)-端(duan)頭(tou)板(ban)-包(bao)角等(deng)。本(ben)文就(jiu)從通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)的整體結構(gou)、材質(zhi)和使(shi)用(yong)環(huan)境等(deng)幾(ji)個方面來談(tan)(tan)談(tan)(tan)通(tong)(tong)風(feng)天(tian)窗(chuang)/氣(qi)(qi)樓(lou)的使(shi)用(yong)年限(xian)。

首先談下通風天(tian)窗/氣樓的(de)(de)材質，（1）天(tian)窗骨架和(he)筏(fa)板(ban)(ban)(ban)(ban)(ban)(ban)骨架、牽引拉桿(gan)、筏(fa)板(ban)(ban)(ban)(ban)(ban)(ban)中軸(zhou)、傳動軸(zhou)等可選(xuan)(xuan)用(yong)(yong)(yong)的(de)(de)材料(liao)有冷(leng)、熱鍍(du)(du)鋅方管和(he)不(bu)(bu)銹(xiu)鋼(gang)(gang)方管。同(tong)樣的(de)(de)壁厚和(he)使(shi)用(yong)(yong)(yong)環境條件(jian)下，金屬使(shi)用(yong)(yong)(yong)年限為：冷(leng)鍍(du)(du)鋅方管＜熱鍍(du)(du)鋅方管＜不(bu)(bu)銹(xiu)鋼(gang)(gang)方管。（2）擋雨板(ban)(ban)(ban)(ban)(ban)(ban)一(yi)(yi)般選(xuan)(xuan)用(yong)(yong)(yong)FRP采(cai)光板(ban)(ban)(ban)(ban)(ban)(ban)或陽光板(ban)(ban)(ban)(ban)(ban)(ban)。其使(shi)用(yong)(yong)(yong)壽命和(he)產品的(de)(de)等級(ji)、厚度或層(ceng)數(shu)、質保期長短(duan)有關。（3）側封板(ban)(ban)(ban)(ban)(ban)(ban)、脊瓦、泛(fan)水(shui)板(ban)(ban)(ban)(ban)(ban)(ban)、集水(shui)槽(cao)、端頭板(ban)(ban)(ban)(ban)(ban)(ban)等一(yi)(yi)般選(xuan)(xuan)用(yong)(yong)(yong)彩鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)、鍍(du)(du)鋁鋅板(ban)(ban)(ban)(ban)(ban)(ban)或不(bu)(bu)銹(xiu)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。同(tong)樣的(de)(de)壁厚和(he)使(shi)用(yong)(yong)(yong)環境條件(jian)下，使(shi)用(yong)(yong)(yong)壽命為：彩鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)＜鍍(du)(du)鋁鋅板(ban)(ban)(ban)(ban)(ban)(ban)＜不(bu)(bu)銹(xiu)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。

再(zai)次就是(shi)使(shi)(shi)用(yong)(yong)(yong)環(huan)境對通(tong)風(feng)天(tian)(tian)(tian)(tian)窗/氣(qi)樓(lou)(lou)(lou)的(de)(de)(de)影響，眾(zhong)所(suo)周知，高溫高濕和腐蝕性強的(de)(de)(de)環(huan)境對通(tong)風(feng)天(tian)(tian)(tian)(tian)窗/氣(qi)樓(lou)(lou)(lou)壽命(ming)的(de)(de)(de)影響是(shi)很大的(de)(de)(de)。一般在(zai)工(gong)程立項階段設計單位就會根據建筑(zhu)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)性質，在(zai)選用(yong)(yong)(yong)通(tong)風(feng)天(tian)(tian)(tian)(tian)窗/氣(qi)樓(lou)(lou)(lou)的(de)(de)(de)規格型(xing)號和材質都會綜合考量。總體思路是(shi)建筑(zhu)整體構(gou)件大于通(tong)風(feng)天(tian)(tian)(tian)(tian)窗/氣(qi)樓(lou)(lou)(lou)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)年限(xian)。隨著近些(xie)年防(fang)腐防(fang)銹技術的(de)(de)(de)進步，以及在(zai)通(tong)風(feng)設備領(ling)域的(de)(de)(de)廣(guang)泛應用(yong)(yong)(yong)，通(tong)風(feng)天(tian)(tian)(tian)(tian)窗/氣(qi)樓(lou)(lou)(lou)產品的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命(ming)整體上了一個臺階。
