鋼結構房屋的優(yōu)缺點有哪些？

What are the advantages and disadvantages of steel structure houses?

　　鋼結構房屋安裝速度快，施工壓力較??；表面有漆，起到防水作用；抗震能力強，系數高。但是表面若不定期維護，容易生銹；鋼材在高溫下強度減弱，易發(fā)生火災；房子建成后不可隨意更改結構。鋼結構房屋的優(yōu)缺點具體如下：

Steel structure houses have fast installation speed and low construction pressure; The surface is coated with paint to provide waterproofing; Strong seismic resistance and high safety factor. But if the surface is not regularly maintained, it is easy to rust; Steel weakens its strength at high temperatures and is prone to fire; After the house is built, the structure cannot be changed arbitrarily. The advantages and disadvantages of steel structure houses are as follows:

　　一、優(yōu)點

1、 Advantages

　　1、施工便捷

1. Convenient construction

　　鋼結構房屋在建造時，主要使用的材料就是鋼結構和一些金屬制成的小構件。所以整體的安裝速度快，工人們的施工壓力較小，極大地縮短了施工時間。

When constructing steel structures, the main materials used are steel structures and small metal components. So the overall installation speed is fast, and the workers have less construction pressure, greatly reducing the construction time.

　　2、防水性好

2. Good waterproof performance

　　鋼結構房屋的主體就是鋼，表面有一層漆，可以起到良好的防水作用。

The main body of a steel structure house is steel, with a layer of paint on the surface that can provide good waterproofing.

　　3、抗震性好

3. Good seismic resistance

　　鋼結構房屋的主要承重構重構件都是鋼，具有良好的韌性和彈性，整體結構的穩(wěn)定性強，即使發(fā)生地震，房子也不會立即倒塌，減少了死傷，系數高。

The main load-bearing components of steel structure houses are made of steel, which has good toughness and elasticity. The overall stability of the structure is strong, and even in the event of an earthquake, the house will not collapse immediately, reducing casualties and having a high safety factor.

　　二、缺點

2、 Disadvantages

　　1、容易生銹

1. Easy to rust

　　雖然鋼結構房屋的表面有一層漆可以起到一定的防水作用，但若是不定期維護也很容易生銹。

Although a layer of paint on the surface of a steel structure house can provide some waterproofing, it is also prone to rusting if not regularly maintained.

　　2、防火性差

2. Poor fire resistance

　　鋼材在高溫下，強度會減弱很多，自身會快速升溫，導致室內溫度過高，極其容易發(fā)生火災。

At high temperatures, the strength of steel decreases significantly, and it rapidly heats up, leading to high indoor temperatures and an extremely high risk of fire.

　　3、不可改變結構

3. Cannot change structure

　　鋼結構的房子一旦建成，就不能隨意改變結構了，因為各個構件之間都是恰好連接在一起的，私自更改會出現很多問題。

Once a steel structure house is built, the structure cannot be changed arbitrarily because the various components are precisely connected together, and making unauthorized changes can lead to many problems.
