What are the advantages of light steel structure houses?

When it comes to light steel, everyone must be familiar with it, it is an important part of building a house. Because the light steel structure house can be easily and quickly assembled and disassembled, it is widely used in the temporary construction of various construction sites, and has established the building concept of environmental protection, energy saving, high efficiency and speed. Regarding the comprehensive cost of the current light steel structure house, it can be analyzed from two aspects, which is the "clear water room" without decoration and the "finished house" with all the decoration and electrical configuration.

Because the light steel structure building system is different from the traditional practice, many pipelines in its fine decoration part are pre-contained in the wall, so the two cannot be categorically separated.

In the first case, the current comprehensive cost is about 1500-1800 yuan square meters, with the continuous improvement of the degree of industrialization and the further optimization of the building materials used, the cost is expected to be reduced. In the second case, it is even lower than the cost of renovation on the current market. The economic benefits of this type of house are already evident in terms of increasing the usable area by about 10%-15% compared to traditional buildings.

There are many advantages of light steel structure housing compared with traditional housing, such as: we all know that the cost of steel structure housing is basically the same as that of traditional concrete structure, but the usable area can be 5% more, and the average carbon emission is about 35% lower, which is an ideal choice for the development of low-carbon economy. Light steel structure housing refers to the use of steel structure as a load-bearing structure, with environmental protection, lightweight, energy-saving materials as the enclosure structure of the house.

At present, steel structure buildings account for less than 5% of the entire construction industry in China, while developed countries have reached more than 50%. The development space of China's residential steel structure is very large.

Light weight, seismic resistance, temperature insulation, waterproof, heat insulation, sound insulation functions, the same construction area of the building floor, the steel structure weight is light, according to the comparison, the weight of the six-story light steel structure house, only equivalent to the weight of the four-story brick and concrete structure house. Moreover, the steel has ductility and can consume the energy brought by the first class relatively well, so the seismic performance is good and the structural safety is high. The steel plate itself has the functions of temperature insulation, waterproofing, heat insulation, and sound insulation.

The construction is convenient, the construction period is short, and the steel structure components can be produced in factories and installed on site. Due to the small amount of on-site operation, there is less pollution to the surrounding environment, and at the same time, the construction mechanization degree is high, which accelerates the construction speed. According to statistics, the same area of buildings, steel structure than concrete structure construction period can be shortened by 1 3, and can save formwork materials, the comprehensive cost is low, due to the light weight, the foundation cost is reduced, the overall material is reduced, the direct cost is reduced, the construction period is short, and the indirect cost can be reduced, so the comprehensive cost is low, in line with the requirements of residential industrialization and sustainable development.

Advantages of light steel house: low cost, no harmful substances, good safety performance, fire prevention, insect prevention. Disadvantages of light steel houses: expensive cost, internal structure can be dismantled at will, materials, etc.

Advantages of light steel self-built houses:

1. The cost is low, the foundation treatment is simple, the scope of application is wide, the foundation cost is about half of the traditional building, and the construction is fast, the construction period is short, and the labor cost is saved.

2. No harmful substances are produced. Since the house is built with screws and nails connected to each other, no welding or adhesives are used, so there are no hazards such as chemicals, and there is no lot of dust or noise during construction.

3. Good safety performance, high strength, light weight, easy to transport and install. There will be no breakage due to accidental overload or local overload. In addition, its weight is only one-fifth of that of the brick-concrete structure, which can effectively reduce the load and improve safety.

4. Fireproof and insect-proof, the steel is deeply galvanized and protected during manufacturing, so it can effectively prevent termite invasion and automatically repair the damaged layer.

5. The thermal insulation effect is good, this kind of house adopts the external insulation method, which covers the skeleton from the outside with thermal insulation and moisture-proof materials, and then matches the thermal insulation layer, air layer and external wall, which can be effectively insulated.

6. Recyclable, steel is the main material for building houses, not easy to lose and age, and waste steel can be fully utilized.

Disadvantages of light steel self-built houses:

1. The cost is more expensive than the traditional structure of the house.

2. The internal structure is fixed, and the wall cannot be dismantled and rectified at will.

3. There are more requirements for materials.

4. The steel structure is fireproof, but it is not resistant to high temperature, if a fire occurs, as long as the temperature reaches more than 500 degrees, it will melt.

1. Advantages: The construction process is simple, which can save time and effort, and is convenient and fast. At the same time, it is also very environmentally friendly and does not produce substances harmful to the human body.

The cost is low and cost-effective. The structure is stable, not easy to collapse, and the safety index is high. In addition to these advantages, it is also fireproof, which can reduce the probability of fire.

2. Disadvantages: Compared with ordinary houses, light steel structure houses cannot remove walls, which is more troublesome in decoration. Low corrosion resistance and cannot be left untouched in wet environments. Because of its low dead weight, it cannot carry heavy loads and has poor load-bearing capacity.

Hello! Good structural performance, light weight, high strength, good seismic performance.

Steel can be more energy-saving and environmentally friendly than masonry and concrete.

Factory processing, quality ***.

The dead weight is light and the foundation cost is low.

The on-site construction period is short.

There is basically no wet work on the site, and there will be no dust, sewage and other pollution.

The cross-section of the structural members is small, the columns are thin, the walls are thin, and the building has a large usable area.

The disadvantages (some are called shortcomings are not exact, and should be called the reasons why they are not suitable for the domestic market at present) require skilled workers to install.

The cost may be slightly expensive.

Rely heavily on industrial support, such as prefabricated wall panels, roof panels, wall filling insulation materials, and fireproof materials. In the form of concrete and masonry structures that are now popular in China, the walls are basically on-site wet masonry, while the light steel structure requires dry prefabricated wall panels.

It is necessary to match the interior decoration materials, devices and methods, such as the method of installing water heaters, air conditioners, and picture frames on prefabricated wall panels and the methods of installing them on masonry walls are still very different, and then such as the waterproof practices and sound insulation practices of profiled steel plate floors.

Hope, thank you.

Light steel structure houses have been very widely used in modern society, and light steel structure houses can be seen in tourist buildings, gymnasiums and warehouses and other fields, but many people have little understanding of light steel structure houses, and do not know the advantages and disadvantages of light steel structure houses, so what are the advantages and disadvantages of light steel structure houses? What are the differences between light steel integrated houses and ordinary steel structure houses?

1. What are the advantages and disadvantages of light steel structure houses.

Advantages: low cost, compared with traditional buildings, the cost can be saved by more than half, wide range of application, simple construction process; Strong environmental protection, not easy to produce toxic substances; Not only is it light and easy to handle, but it is also safe and fireproof. Cons:

Light steel structure houses cannot be demolished for rectification; It has poor corrosion resistance and high temperature resistance, and is very easy to corrode in a humid environment.

Second, the difference between light steel integrated houses and ordinary steel structure houses.

1. Light steel keel is the main construction material of light steel integrated house, with good bearing capacity, can replace traditional houses, the main material of ordinary steel structure houses is steel materials, the bearing capacity is relatively poor, can not replace traditional houses, so it is often used to build venues and workshops.

2. The structure of the light steel integrated house is mainly made of steel plates and section steel, and the steel columns and steel beams and other components made of these two materials can greatly increase the bearing capacity of the building, and the weight is relatively light, and it is convenient to transport at the same time, and the construction is also more convenient, so the scope of application is relatively wide.

3. Compared with ordinary steel structure houses, light steel integrated houses have better environmental performance, all materials can be utilized, and light steel integrated houses can be relocated, and it is also very convenient to modify them in the later stage.

Summary: What are the advantages and disadvantages of light steel structure houses are introduced here, light steel structure houses have advantages and disadvantages, but due to the wide range of application, they have been widely used in temporary houses, warehouses, daily supermarkets and other places, which has brought great convenience to people's lives.

1. The biggest disadvantage.

The cost is high, and it needs to be overhauled and maintained regularly, which is more troublesome. Light steel houses have thin walls and are not soundproofed. Extremely poor fire performance. Not resistant to moisture. The quality is uneven, and now the whole industry is not perfect.

2. Fire prevention. One of the most critical issues of light steel villas is the application of fire prevention technology, and the fire resistance level of light steel villas has four levels. Among them, the glass fiber wool filled between the wall columns of the wall is a class A fireproof material, which also plays a positive role in protecting fire prevention and transmission.

3. Keep warm. In order to ensure the thermal insulation effect, the thermal insulation materials used in the exterior walls and roofs of the building can be used for a long time and can be insulated. In addition to filling the glass fiber between the wall columns of the wall, the light steel villa generally pastes a layer of insulation material on the outside of the wall to 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.

4. Sound insulation. Light steel villas are filled with glass wool between the interior and exterior walls and floor joists, which can effectively prevent the audio part from being transmitted through the air. For the impact sound propagating through the solid, the following structure is used:

For the sub-household wall, two wall columns are used to form a two-way wall with an intermediate void; For the small keel of the fixed gypsum board for the suspended ceiling, the elastic structure with small grooves is used to effectively reduce the solid sound transmission between floors.

5. Maintenance. Light steel villas are mainly composed of steel structures, so the prevention of steel structure rust has become a very important maintenance problem, the best light steel villa manufacturers will generally use a special paint for painting, in order to prevent steel structure rust.

The maintenance of light steel villas needs to pay attention to the place, because most of the light steel villa houses are built of light steel, a screw and a hole, and the threads are inseparable from each other, so special attention should be paid to the decoration of light steel villas. Moreover, the tiles of the light steel villa roof also need to be replaced regularly (preferably once every 5 years) to prevent rain leakage.

The exterior wall of the light steel villa should be regularly maintained with special paint, and the roof asphalt shingle should be replaced once every 5 years according to the actual situation. The structural components of the light steel villa are linked as a whole, and the user can not wrap the line around the steel structure when setting up the power line, and the line pipe or line isolation groove should be set up to avoid short circuit circuit.

6. Moisture-proof ventilation.

The walls and roof are equipped with ventilation layers to create a natural wind effect by using the difference between air density and temperature. A one-way breathable layer is set up in the composite fence structure to make the wall and roof have a "breathing" function.

7. Poor durability.

The structural parts must be galvanized with special anti-corrosion treatment, so it can protect the steel from rust and prolong the service life of the steel; The enclosure material adopts new lightweight building materials, flame retardant, mildew-free and moth-proof.

<> advantages of light steel structure houses: 1. Low cost and environmental protection. The overall cost is relatively low, and compared with traditional house construction, the cost of light steel structure houses can be saved by about half.

In addition to this, this type of house has a wide range of applications, and it is environmentally friendly and does not produce toxic substances. 2. This kind of house is light in texture, which is conducive to transportation, and it is also very fireproof. Disadvantages of light steel structure houses:

1. Light steel structure houses cannot be dismantled and modified independently. 2. The corrosion resistance and high temperature resistance are not good. If it is not cleaned in time when exposed to water, it will be easy to be damp and corroded.

So on the whole, light steel structure houses are cost-effective.
