東莞南沙群島鋼結構工程的優(yōu)點是？

? 鋼結構工程是以鋼材制作為主的結構，主要由型鋼和鋼板等制成的鋼梁、鋼柱、鋼桁架等構件組成，各構件或部件之間通常采用焊縫、螺栓或鉚釘連接，是主要的建筑結構類型之一。因其自重較輕，且施工簡便，廣泛應用于大型廠房、橋梁、場館、高層等領域。東莞鋼結構工程的優(yōu)點是？

1、抗震性：低層別墅的屋面大都為坡屋面，因此屋面結構基本上采用的是由冷彎型鋼構件做成的三角型屋架體系，輕鋼構件在封完結構性板材及石膏板之后，形成了非常堅固的"板肋結構體系"，這種結構體系有著更強的抗震及抵抗水平荷載的能力，適用于抗震烈度為8度以上的地區(qū)。

2、抗風性：型鋼結構建筑重量輕、強度高、整體剛性好、防變形能力強。建筑物自重僅是磚混結構的五分之一，可抵抗每秒70米的颶風，使生命財產(chǎn)能得到有效的保護。

3、耐久性：輕鋼結構住宅結構全部采用冷彎薄壁鋼構件體系組成，鋼骨采用防腐高強冷軋鍍鋅板制造，有效避免鋼板在施工和使用過程中的銹蝕的影響，增加了輕鋼構件的使用壽命。結構壽命可達100年。

4、保溫性：采用的保溫隔熱材料以玻纖棉為主，具有良好的保溫隔熱效果。用以外墻的保溫板，有效的避免墻體的“冷橋”現(xiàn)象，達到了更好的保溫效果。100mm左右厚的R15保溫棉熱阻值可相當于1m厚的磚墻。

5、隔音性：隔音效果是評估住宅的一個重要指標，輕鋼體系安裝的窗均采用中空玻璃，隔音效果好，隔音達40分貝以上；由輕鋼龍骨、保溫材料石膏板組成的墻體，其隔音效果可高達60分貝。

6、健康性：干作業(yè)施工，減少廢棄物對環(huán)境造成的污染，房屋鋼結構材料可100%回收，其他配套材料也可大部分回收，符合當前環(huán)保意識；所有材料為綠色建材，滿足生態(tài)環(huán)境要求，有利于健康。

7、舒適性：輕鋼墻體采用節(jié)能體系，具有呼吸功能，可調節(jié)室內(nèi)空氣干濕度；屋頂具有通風功能，可以使屋內(nèi)部上空形成流動的空氣間，保證屋頂內(nèi)部的通風及散熱需求。

8、快捷：全部干作業(yè)施工，不受環(huán)境季節(jié)影響。一棟300平方米左右的建筑，只需5個工人30個工作日可以完成從地基到裝修的全過程。

9、環(huán)保：材料可100%回收，真正做到綠色無污染。

10、節(jié)能：全部采用節(jié)能墻體，保溫、隔熱、隔音效果好，可達到50%的節(jié)能標準。
