Are steel structure self-built houses really suitable for rural areas?

In recent years, more and more people in rural areas choose steel structure to build houses. Can it really be better than heavy reinforced concrete houses? In fact, this is not the case. Although steel structure houses have many advantages over traditional houses, the disadvantages are also obvious. Today, I will share with you the pros and cons of it.

1. Performance advantages

1. Strong bearing capacity, large span and light weight

ratio From a reinforced concrete brick house, although the steel structure is light in weight, its load capacity is very strong! It can not only reduce the requirements for foundation foundation, but also facilitate transportation and construction.

The style of steel structure buildings is more flexible, with large bay design, and the indoor space can be divided into multiple schemes to meet the different needs of everyone.

2. The steel material is uniform, with good plasticity, toughness and good seismic performance. Strength is close. The steel members have good plasticity and will not break suddenly due to accidental overloading or local overloading. Good toughness makes the steel structure more adaptable to dynamic loads.

In addition to the lightweight characteristics of steel structure, the seismic and wind resistance performance of steel structure villas is much better than that of traditional houses. It can better protect the life and property safety of the owner, and you can rest easy.

3. Industrial production, easy to manufacture and high precision

Steel structures are all manufactured in professional steel structure factories, with simple production and high precision. The finished components are transported to the site for assembly and connected by bolts, which is convenient for construction. The completed steel structure is also easy to dismantle and reinforce.

4. Short construction period

Beams, columns, wall panels and roofs all adopt prefabricated installation methods, only need The reinforced concrete is cast in place on the floor, and the construction speed is fast. Compared with traditional houses, the construction period can be shortened by 2/3.

5. Energy saving and emission reduction, green environmental protection , Cement, water use less, more than 80% of the materials can be recycled, saving energy and protecting the environment, especially in the construction site, the pollution is lower.

6. Humanized decoration

The steel structure self-built house itself has a natural sense of heaviness and decoration, coupled with other decoration elements, modern Full of feeling!

Everything has a good side, and of course there is a bad side. We all need customers to compare and analyze, and we can't be blind!

Second, performance disadvantages

Although steel structure villas have many advantages above, their defects cannot be ignored.

1. No corrosion resistance

This is the biggest problem of steel structure houses. Without concrete protection, corrosion will easily occur. In particular, the welded connection between the components is the most prone to rust. Although it can be improved by hot-dip galvanizing and painting, it must be maintained regularly, otherwise the service life of the steel structure villa will hardly exceed 15 years.

2. Heat resistance but not fire resistance

When the temperature is between 300℃ and 400℃, the strength and elastic modulus of the steel decrease significantly. At about ℃, the strength of steel tends to zero. Relatively speaking, the fire resistance of steel structure houses is weaker than that of traditional houses.

3. Strong professionalism

Steel structure construction requires a professional construction team, especially the positioning, connection and review of steel columns require a skilled installation team , professional workers to carry out construction, general construction team can not do.

Three, the cost

The cost of steel structure housing is not expensive, but the price of steel has risen sharply this year. The rough house is actually not more expensive than the reinforced concrete frame structure. Before, 1,200 yuan/㎡ was basically enough, but now it will rise to about 1,500 yuan. As the tide rises, it is impossible to do so.

In general, steel structure houses have obvious advantages over traditional structure houses, but the biggest hidden danger is the problem of rust. Friends, if you really plan to build your own with steel structure For houses, hot-dip galvanized steel can be used, but the construction cost will increase by at least 30%. Local tyrants can consider it, and friends with limited economic conditions, please consider carefully.
