What is the future prospect of steel structure villas?

With the continuous development of China's construction technology, prefabricated villas are gradually promoted in China, and steel structure villas have the advantages of fast construction, labor saving, and reduced consumption.

The state has repeatedly introduced relevant policies to promote prefabricated buildings, which is naturally not untargeted. Its implementation is a transformation to a green mode of production at the national and social levels; For individuals, it is a healthy, comfortable and green building quality and an upgraded indoor environment living experience. In terms of design, we will continue to practice the concept of green building, make the building more "green", and add low-energy consumption and passive design to the prefabricated housing to create a healthy living environment; At the same time, more technologies to improve comfort will be introduced to achieve both health and comfort, and improve the quality of the house to a higher extent.

The production mode of the traditional construction industry has been unable to meet the development needs of the times, and the prefabricated steel structure villa has also entered the fast lane of development. As a comprehensive service provider of prefabricated steel villas in China, Yunshu Construction responds to national policies and builds the most beautiful villages.

Light steel structure villa** in North America Its structure is naturally stable In recent years, affected by the international environment, steel ** has continued to decline; Coupled with the continuous operation of steel production and the continuous release of production capacity, the pressure on steel inventory has increased, and the cycle of travel has led to the current steel market in the "worst period". Such an environment provides the "best opportunity" for the steel structure integrated house in the steel industry chain. Nowadays, people's requirements for self-built houses are no longer limited to the requirements of good looks, long living time, and convenient construction, and have begun to take the direction of personalized development.

The materials used for the prefabricated house are mainly color steel plates, which are relatively simple. Safe and practical, suitable for temporary construction on the construction site, recyclable; Light steel structure houses are mainly made of light steel keel, which is light in weight, environmentally friendly and energy-saving, and suitable for living. The appearance, materials, and interior of the self-built house have many requirements, which can be cast in situ or sprayed.

Preventing the rust of the steel structure has become a very important problem, and the best light steel structure villa steel structure will be painted with a special paint to prevent the steel structure from rusting. The cast-in-place solid concrete layer is usually reinforced with steel wire mesh or steel bars to limit shrinkage cracks and ensure the strength of the shell. The spraying method can apply a sand pump to the surface of the steel structure on the construction site to form a protective layer, and the sand pump can be lime cement or gypsum mortar, and can also be mixed with perlite or asbestos.

Light steel villas are produced by prefabricated parts, and it is agreed that the assembly line has fast production speed and high quality; Then transport to the construction site to directly build and assemble, shorten the construction time on the construction site, reduce the unnecessary labor cost expenditure. Light steel structure villa has the advantages of high strength, light weight, good seismic performance, low foundation cost, large building use area, high building quality, suitable for industrialization and standardized production, dry green construction, suitable for different climatic conditions, not affected by the construction season, and low comprehensive cost. At the same time, it can also reduce the pollution of construction waste to the environment and can be recycled in the whole life cycle, which has become the preferred material for villa construction in today's era.

It forms a very strong and sturdy "plate rib structure system". In the event of a strong **, it seems that the steel structure only accounts for 10% of the total cost of the project, and the share is not much. ，

Steel structure light steel villas or low-rise cold-formed thin-walled steel villas are a trend, and there will be more and more applications in suburbs or rural areas. This kind of structural system has a fast construction speed and a large usable area, and can have relatively rich façade shapes.

Good.

The steel structure villa has good seismic performance, but the villa uses very little steel structure, and the cost is high.

The steel structure house is light in weight, only about one-fifth of the brick-concrete structure house, and the reinforced concrete structure.

About one-eighth of the house, so it can greatly reduce the cost of foundation construction, light steel structure house.

The foundation is generally a strip foundation.

Can. <>

Light steel villa, also known as light steel structure house, its main material is a light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology, after accurate calculation plus the support and combination of accessories, to play a reasonable bearing capacity, in order to replace the traditional house.

Advantages of light steel villas:

1. The weight is very light, the stability is good, and it has very good seismic and wind resistance. The construction speed of light steel villas is 7-8 times that of ordinary buildings, and it is basically dry construction without involving water problems. Light steel villas may only weigh a quarter to one-sixth of a traditional concrete building, and the mass is very light.

Its stability is excellent, and the steel structure of the house has very good seismic and wind resistance. Paste a layer of insulation material on the outside of the wall, so that the thermal insulation effect can be achieved and play the role of thermal insulation and sound insulation.

2. Light steel materials can also be recycled, green and environmentally friendly. In addition, the life span of light steel villas can reach more than 70 years, while the traditional brick-concrete structure is 50 years.

Of course, it's good, and the seismic performance is good. However, the villa adopts very few steel structures, and the cost is high.

The main body is made of light steel keel load-bearing, and the wall and roof are composed of keel, thermal insulation materials, moisture-proof and soundproof materials, and the house performance can be compared with foreign advanced passive houses! The construction of light steel villas adopts the dry construction method, which will not cause waste of water materials and save costs.

Moreover, the fully assembled construction technology shortens the construction period of one and a half years to only three months, which is very convenient. And the flexible main body structure can resist level 9** without falling! Because the wall thickness of the light steel structure is small, the light steel villa can increase the effective use area compared with the brick-concrete structure.

Light steel structure villas are reliableThe light steel structure villa is a reliable use of the main building materials for the prefabricated house, H-shaped steel, and color steel sandwich panel as the main load-bearing skeleton and main wall system, which is quite good in terms of load-bearing and solidity.

The light steel structure has good seismic performance. Because the activity of the first is left and right and up and down, the light steel structure connected together with screws forms a safe and stable box, and the wall will not collapse or the floor will fall down because of the shaking of the first and endanger personal safety.

Because the wall thickness of the light steel structure is small, it can increase the effective use area compared with the brick-concrete structure. All the building materials are produced by the factory with high precision, with a high degree of industrialization, transportation and on-site installation, rapid construction speed, and low labor loss.

Light steel structure villas are reliable. The main building materials, H-shaped steel, and color steel sandwich panels for prefabricated houses are mainly used as the main load-bearing skeleton and main wall system.

The tile surface is made of glazed colored tiles, the outer wall can be nested with different material plates, and the inner wall can be nested with inner decks according to needs to make the interior wall texture that is no different from ordinary houses. This forms a civil residence with the appearance of a villa and a small bungalow.

After more than 100 years of development, it has formed a mature construction system with excellent physical properties, flexible space and shape, easy to build and various forms. In the North American continent, which is known as the best living environment in the world, more than 95% of low-rise civil buildings, including residences, shopping malls, schools, office buildings, etc., are built with wood or light steel structures (even our neighbors Japan and South Korea). North American wood and light steel structures have an absolute advantage in the entire construction market.

Reliable. 1. Foundation costs.

Because all the materials of the light steel structure house are light materials, its own weight is light, which can greatly reduce the foundation cost, which is only 1 5 of the brick-concrete structure and 1 7 of the steel-concrete composite structure.

2. Construction costs.

The construction of light steel structure residential buildings is highly industrialized and fast. The construction period is half that of a brick and concrete house. The construction of light steel structure houses is less affected by weather and seasons, and can be carried out under various climatic conditions, so as to achieve uninterrupted construction throughout the year and reduce on-site transportation and hoisting costs.

Under normal circumstances, light steel houses can be moved in within two months.

3. Usable area.

Due to the thin walls, the light steel villa has a large usable area and a high housing rate. The usable area of brick and concrete houses is generally about 75%. The utilization rate of light steel structure houses is as high as more than 90%. With a construction area of more than 200 square meters, you can have an extra small study.

4. Service life and **.

Light steel structure, the application period of 70 years, 70 years to dismantle and renovate the old, about 90% of the utilization rate, saving the cost of dismantling and transportation. Brick-concrete structure, the application period is 50 years, 50 years ago to dismantle the old and renovate, the utilization rate is low, and the dismantling and transportation costs will cost a lot of money.

Light steel structure villas are still more reliable.

Steel villas are mainly composed of steel structures, and many people have the impression that things like steel and iron are easy to rust. So, why do light steel houses have a service life of up to 100 years? This is also thanks to an anti-rust coating, which is also aluminum-zinc AZ150, which is sprayed with both the light steel keel and the screws connecting the keel.

Chemically, the theoretical oxidation time of this anti-rust coating is 300 years, so after the light steel is built, there is no problem at all when it is used normally for 100 years. Because steel and screws have their "protective guards", they are difficult to oxidize by air and are also very strong.

The light steel villa wall belongs to the composite wall, through the combination of structural framework, thermal insulation glass fiber cotton and various maintenance plates, a combined wall system with good performance and a composite roof system with excellent thermal insulation effect. Generally, in addition to filling the wall columns with fiberglass, another layer of insulation material is pasted on the outside of the wall.

Effectively cut off the thermal bridge from the wall column to the exterior wall panel; The joists between the floors are filled with fiberglass to reduce heat transfer through the floors; All interior walls are filled with fiberglass between the columns to reduce heat transfer between the walls. The thermal insulation of the roof of the light steel villa can be paved obliquely along the slope roof or tiled above the top ceiling by means of insulation materials.

The light steel structure is reliable, but it is not very suitable for China's national conditions.

The advantages are light weight and good seismic performance, except for this advantage, everything else is a disadvantage.

China's steel cannot be compared with Europe and the United States.

There is no relevant software in China to do structural design, and if there is, it is not mature, and I am afraid that the design cost of a design is 10 times that of ordinary design costs.

Imported machines are too high, and the light steel industry is less competitive and expensive.

Light steel and plate are jointly stressed, the plate may have indoor pollution, you have to ensure that the use of environmentally friendly materials, will not buy fake and substandard goods.

Light steel is not suitable for large spans, and can only be made of villas and the like. But all Chinese buy villas, they have to go through a transformation, and there is not much room for light steel transformation.

The later maintenance cost of the steel structure is large, and the light steel structure is even worse, it has more corrosion area, and the steel is thinner and wrapped, so the later maintenance is more difficult. If there is a problem with the steel, it should not be discovered.

This structure should be more suitable for Japan, a country with such frequent occurrences.

Is the light steel structure villa good?

The light steel structure house is still relatively reliable, with good seismic performance, although it is a light structure, it is very reliable, and it is an environmentally friendly material that can be recycled.
