Steel structure building is a new type of building system

Steel structure building is a new type of building system, which breaks through the industrial boundaries among real estate, construction and metallurgy industries and integrates them into a new industrial system. This is the steel structure building system widely favored by the industry.

Compared with traditional concrete buildings, steel structure buildings replace reinforced concrete with steel plate or section steel, which has higher strength and better earthquake resistance. And because the components can be manufactured in factory and installed on site, the construction period is greatly reduced.

As steel can be reused, it can greatly reduce construction waste and is more green and environmentally friendly, so it is widely used in industrial and civil buildings all over the world.

Advantages of putian Steel Structure Building:

The steel frame structure has the characteristics of high strength, good anti-seismic performance, simple and quick assembly and construction, etc.

The light steel villa can complete the main building of the house in less than a month. The construction of the light steel structure villa avoids complicated construction procedures, reduces the labor intensity of workers, and finishes most of the interior decoration of exterior decoration boxes.

Light-gauge steel villas save energy, are clean and environmentally friendly, and have relatively low comprehensive cost for construction. Many people easily misunderstand the quality of light-gauge steel villas by looking at the price. We should change our ideas and strongly support the application of light steel structure villas so that more people can understand them.

„Beautiful China“ Calls for Green Architecture

Building energy conservation has become an irreversible trend in the world, and the development of steel structure is the best choice for energy conservation and environmental protection. It is understood that the country is currently working out a building development plan for „saving energy and land“, encouraging the development of steel structures and promoting the construction of „beautiful China“.

Compared with the traditional cast-in-place production method, the steel structure integrated housing construction system can reduce labor by 30%, save construction land by 50%, save water by 60%, save electricity by 60%, reduce noise by 80%, reduce on-site construction waste emissions by 80%, and shorten construction period by more than 30%. Therefore, steel structures are truly „green buildings“.

What is steel structure building?

If one does not intend to understand conceptually, one need only look at the „Bird’s Nest“ and „Water Cube“ of Olympic venues, CCTV’s new office building, Shanghai World Center, etc., and one will know that the so-called steel structure is a building constructed with factory-made steel beams and columns as its framework and with new lightweight, heat-insulating, heat-insulating and high-strength wall materials as its enclosure structure.

Prefabricated building is the embodiment of green building

Prefabricated building is to design the structure produced and formed in the construction of traditional buildings into multiple parts that can be assembled, thus reducing the transportation cost in the application of building equipment, realizing the diversified development of industrial building materials application, not only greatly saving the capital investment in industrial production, but also realizing the flexible application of industrial building materials and the secondary application of building construction materials. It is an important embodiment of the application of low-carbon concept and green building concept in our country’s buildings.

The application of prefabricated buildings in China’s industrial buildings has been continuously developed with the further improvement of the social and economic development level and the social development structure.

On the one hand, the application of prefabricated buildings in industrial building production can be used as a new power for industrial development, and the technical level of industrial production and the universality of technical application can be further improved.

On the other hand, the application degree of fabricated buildings in China’s industrial buildings is low in innovative application factors and low in long-term development of application in buildings, which will adversely affect the long-term development of China’s future industrialization.

It can be seen that there is a long way to go for the application and development of fabricated buildings in China prefabricated homes.

Popular Factors of Light Steel Residential Buildings

Light steel house is a residential building with cold-formed thin-walled steel structure as the load-bearing framework and light wall materials as the enclosure structure. Light steel residential buildings have obvious advantages in energy saving, strategy and green building.

1. The traditional residential buildings have high energy consumption and unsophisticated manufacturing materials and techniques, resulting in a large amount of headache construction waste. As for light steel structure residential buildings, due to their high level of industrialization, they can be constructed in a commercial, universal, modular and standardized way, thus saving a lot of manpower and material resources.

At the same time, the light steel structure residence has a long service life and can be recycled after being dismantled without generating a large amount of construction waste.

2. The seismic performance of light steel structure residence is obviously better than that of traditional brick and concrete structure residence. At the same time, the light steel residential structure is light in weight, and the weight per unit area is only 1/4 of the weight of brick-concrete structure with the same area, so the foundation construction is simple and suitable for most geological conditions.

3. Because the steel used in the building structure is factory processed, the structural accuracy of light steel residential buildings is relatively high. The villa structure system consists of tens of thousands of components, and the average error of each component is less than 2mm, thus ensuring the quality of the house. This is beyond the reach of traditional building methods.

4. Light steel residential buildings have advantages in heat preservation, earthquake resistance, sound insulation, insect prevention and ant prevention, wide application and changeable architectural shapes.

Pay Attention to Anti-corrosion and Anti-rust Treatment of Steel Components

Whether the steel structure buildings is safe and reliable not only involves the safety of life and property, but also causes certain social impact. Therefore, we should have an understanding of the characteristics of the building structure.

As steel structure is mainly made of steel plate, hot rolled steel or cold-formed thin-walled steel, it is formed through various connections, manufacturing and assembly. Compared with other materials of building structures, it has different characteristics.

When steel structures are in a humid or corrosive environment, corrosion will obviously increase. Rust reaction of steel members will not only reduce the cross section of steel members, but also cause rust pits on the surface of steel members. In this case, when the members are stressed, the members will easily deform under pressure, thus affecting the balance of the whole steel structure.

Therefore, in order to ensure the structural safety of the factory, it is necessary to attach importance to the anti-corrosion and anti-rust treatment of steel components, to prevent these details from the design source, and to take corresponding measures in combination with the construction process layout and construction material selection under the environmental conditions of the steel structure factory building.

The steel has good plasticity, which can prevent the steel structure from sudden fracture and damage due to accidental overload or local overload: the steel has good toughness, which is favorable for the steel structure to adapt to vibration load, and the steel structure used in buildings in earthquake area is more earthquake resistant than engineering structures made of other materials. Steel structures are generally structures with little damage during earthquakes, which can be illustrated by comparing the damage of surface frames and concrete frames.

The above is an introduction to the reasons why steel structures are popular. More wonderful contents can be paid attention to us:

Container trailer can be built near the construction site

Today, I brought you the installation skills of Expandable Container Houses. what are you waiting for? come and have a look.

The movable house tells us through summary that the installation of the container movable house is similar to that of a building. It is necessary to level the surrounding and partition wall foundation and use reinforced concrete. Because reinforced concrete is relatively strong, then we use transverse beams to connect the framework, and then we use partition boards, exterior wall panels and door window frames to lay the floor, then install a layer upwards, and then roof truss and roof panel.

The following work is to install doors and windows, etc., and pull the vertical support. Another is the installation and purchase of sanitary ware and hardware. In fact, this is a light steel structure, which has many similarities with heavy steel structure workshops.

Concealed work of container mobile house refers to the interior decoration of the parts that will be covered up by the next process after the completion of the previous process during the construction process and cannot be inspected after the completion of the whole process. The „concealed work“ is very important. If the „concealed work“ is not done well, it is futile to decorate the surface beautifully.

Let’s briefly introduce the so-called „hidden project“, which can be divided into water installation, electricity installation, moisture prevention, waterproof and other projects. Each project is very important and cannot be ignored. If there is a problem in any link, it may cause serious economic losses and even harm to personal safety. It is necessary to identify the construction technology and materials of waterproof engineering to avoid unnecessary economic losses and injuries.

When the container mobile house is built, the original buildings on the construction site must be used first, which can reduce the corresponding costs. We attach great importance to these details, pay attention to the points, and insist on starting in an appropriate way. Considering the actual situation, the movable house should be built as close to the construction site as possible.

Stability Performance of Light Steel Structure House

At present, self-building and villa construction in rural areas have become a trend. PTH light steel villa house has also become the first choice for many people to build their houses. The advantages of choosing PTH light steel structure houses for rural self-building include the following.

PTH light steel structure house:

1. Earthquake resistance: The roofs of low-rise villas are mostly sloping roofs. Therefore, the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. After sealing structural plates and gypsum boards, the light steel members form a very strong „slab-rib structure system“. This structure system has stronger earthquake resistance and horizontal load resistance, and is suitable for areas with earthquake intensity above 8 degrees.

2. Wind resistance: Type II steel structure has light weight, high strength, good overall rigidity and strong deformation capacity. The self-weight of the building is only one fifth of that of brick-concrete structure, which can resist hurricanes of 70 meters per second and effectively protect life and property.

3. Durability: Light steel structure residential structures are all composed of cold-formed thin-walled steel members. Steel skeleton is made of super corrosion-resistant and high-strength cold-rolled galvanized sheet, which effectively avoids the influence of corrosion of steel plates during construction and use and increases the service life of light steel members. The structural life can reach 100 years.

4. Thermal insulation: The adopted thermal insulation material is mainly glass fiber cotton, which has good thermal insulation effect. The insulation board used for the outer wall can effectively avoid the phenomenon of „cold bridge“ of the wall and achieve better insulation effect. The thermal resistance of R15 thermal insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1 m.

5. Sound insulation: The sound insulation effect is an important index for evaluating residential buildings. The windows installed in light steel system are all made of hollow glass. The sound insulation effect is good, with the sound insulation reaching more than 40 decibels. The wall composed of light steel joist and thermal insulation gypsum board has a sound insulation effect of up to 60 decibels.

Light steel villas have formed a mature building system

The construction technology of light steel villa house is based on North American model wood structure. After more than 100 years of development, a mature building system has been formed with excellent physical properties, flexible space and shape, convenient construction and various forms.

In Europe, the United States, Australia and our neighboring countries, Japan and South Korea, light steel villas can be seen everywhere, while residential buildings, shopping malls, schools, office buildings and so on are all constructed with light steel structures.

In China, light steel villas have also entered a stage of rapid development, and have received public attention, recognition and pursuit. Light steel villa low-rise residential building technology conforms to the national industrial positioning of the construction industry and the sustainable development strategy. It has received policy and technical support from relevant government departments at all levels.

The following summarizes several comparative advantages of light steel villas:

  1. There are thermal insulation materials inside, and the thermal insulation performance is far better than that of brick-concrete houses and villas.
  2. Sound insulation effect is good, filling sound insulation cotton completely blocks the transmission of noise.
  3. Beautiful appearance, can be customized according to personal requirements, appearance can do any function.
  4. It can be recycled and can become a renewable resource for environmental protection.
  5. High taste and unique taste shape extraordinary life.

The technology and product configuration of light steel structure are very mature and have a high degree of industrialization. It is the crystallization of the development of North American construction technology and building materials industry in the past 100 years. Galvanized steel used in building structures has excellent corrosion resistance and durability, and its service life under normal use exceeds 70 years. The life span of traditional houses in China is very short. The average life span is less than 30 years, which is only half of the design life span.
