What are the advantages and disadvantages of light steel structure housing?

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.

Merit. 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, and wall filling insulation materials.

1 Uses. Where is light steel used? @猪小宝 Do you think you are promoting residential use?

I don't think it's appropriate. First of all, self-built houses in rural areas, the cost is really high, and where to find skilled workers? Then there are the high-rise buildings in the city, the carrying capacity is not enough, and the two or three floors are over, and they cannot be used.

All that's left is to build villas, the question is how many villas we need. What about it

Although we always have a once-in-a-millennium flood and a once-in-a-10,000-year flood, the actual situation should be considered in earthquake resistance, and it makes sense to pursue 8 degrees and 10 degrees one-sidedly.

2 About the so-called "merits".

Steel can be more energy-saving and environmentally friendly than masonry and concrete A building is less than 50 years, and who can say the technology after 50 years. Isn't it too early to plan for 50 years from now** and calculate the benefits (as far as I know, the total cost will increase by more than 40%)

There is basically no wet work on the site, and there will be no dust, sewage and other pollution Where is the floor slab. We don't have wet work, so we sleep on the patio.

The cross-section of the structural components is small, the columns are very thin, the walls are very thin, and the building has a large usable area. The thickness of the wall cannot be considered only by that area.

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.

Villa Master.

1. The cost of light steel villas is slightly more expensive than ordinary villas, and you also need to find a professional construction team.

2. The materials used in light steel villas do not have the properties of thermal insulation, so they are not suitable for living in cold winters.

3. Light steel villas are not resistant to moisture and fire, so they cannot be built in the rainy south.

4. The walls of light steel villas are very thin, so the sound insulation effect will be very poor.

5. Light steel villas need to be bothered in the later maintenance, and they should be regularly checked to see if there are corroded parts and repaired regularly.

The cost is slightly expensive, and the cost and tools are too expensive.

The actual effect of sound and heat insulation may be inferior to traditional concrete houses due to operational problems.

When you tap the wall with your hand, there will be an "empty" sound.

Generally, the wall is 13mm gypsum board, which will be broken when it is beaten, and there is a sense of insecurity.

Heavily dependent on industrial support, such as prefabricated wall panels, roof panels, wall filling insulation materials, fireproof materials, light steel structures need dry prefabricated wall panels.

It needs to be overhauled and maintained regularly, because the durability of steel is still not as good as concrete, and it is not as "spicy" as concrete

Can light steel villas be built? Listen to the real estate people talk about the shortcomings, are you okay with it?

As a prefabricated house, the internal structure of Sunshine Mansion Light Steel Villa can realize dry structure, fast assembly, high precision, and the construction period can be completed within 1-2 months.

The cost is slightly expensive, and the cost and tools are too expensive. The actual effect of sound and heat insulation is not as good as that of traditional concrete houses. When you tap the wall with your hand, there will be an "empty" sound.

Generally, the wall is 13mm gypsum board, which is insecure. Relying heavily on industrial support, the light steel structure needs to be prefabricated by dry method. It needs to be overhauled and maintained regularly, because the durability of steel is not as good as concrete, and it is not as "spicy" as concrete

What about the disadvantages of light steel villas?

1. Depending on the design or construction and decoration standards, the cost may be slightly higher than that of a traditional brick-concrete building.

Two: after the installation of light steel villas, for the owner, can not change its structure privately, can not remove any bolts and other components, can not increase or decrease the partition wall, if you need to replace which parts must be negotiated with the manufacturer, by the manufacturer to judge whether it can be replaced.

Three: the light steel villa manufacturers on the market are mixed, and some manufacturers rely on low prices to attract customers and then use their routines, or use cheaper inferior materials to shoddy.

Four: the current acceptance of light steel villas is relatively low, in people's perception of light steel is not strong, but in fact, light steel strength, durability is stronger than traditional buildings.

Although the house was repaired quickly, it was not soundproofed and not warm.

The technology and product configuration of light steel structure are very mature, with a high degree of industrialization, and it is the crystallization of the development of construction technology and building materials industry in North America in the past century. The galvanized steel sheet used in the building structure has excellent corrosion resistance and durability, and its service life under normal use is 275 years.

The seismic performance of light steel structures is far superior to that of traditional concrete and brick concrete houses. At the same time, because the structure of the light steel structure is light, the weight per unit area is only equivalent to 1 4 of the weight of the same area of brick-concrete structure, so its foundation treatment is simple, and it is suitable for most geological conditions. Steel structure houses are no longer as worried about termite damage as wood frame houses.

Because the steel used in the structure is processed by factory, the structural accuracy of the light steel structure villa is quite high, and the structural system of a villa is composed of tens of thousands of components, and the average error of each component is less than 2 mm, which ensures the quality of the house, which is unattainable by the traditional construction method.

If you don't have a specific understanding, you dare to talk nonsense, and people's hearts are not ancient.

Advantages of light steel structure housing:

1. Good structural performance, light weight, high strength, good seismic performance;

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

3. Light weight and low foundation cost;

4. The on-site construction period is short;

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

6. The cross-section of the structural components is small, the columns are very thin, the walls are very thin, and the building use area is large.

Disadvantages of light steel structure housing:

1. Skilled workers are required to install;

2. The cost may be slightly expensive;

3. Rely heavily on industrial support, such as prefabricated wall panels, roof panels, wall filling insulation materials, and fireproof materials. Concrete, which is now popular in China;

4. The masonry structure form wall is basically on-site wet masonry, while the light steel structure needs dry prefabricated wallboards;

5. It requires the matching of interior decoration materials, devices and methods, such as the method of installing water heaters, air conditioners and picture frames on prefabricated wall panels is very different from the method of installing them on masonry walls now;

6. It needs to be regularly overhauled and maintained, and the durability of steel is not as good as that of concrete.

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.
