Prefab House refers to a building where parts and components produced in a factory are assembled and connected at the construction site. Steel structure prefabricated buildings refer to steel structure components produced in factories and assembled and connected at the construction site.
Different countries have different understandings and practices of the housing system, but Prefab House generally refers to the main project of the house. Different residential products are formed due to the selection of different structural materials, structural types and construction methods, and constitute a number of corresponding residential products ranging from design to The complete technology of construction. The steel structure residential building system uses the steel structure form as the basis for the classification of the building system and becomes a branch of the building system.
The material of Prefab House has good homogeneity and isotropy, which is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformations, and can well withstand dynamic loads; construction period is short ; It has a high degree of industrialization and can be used for specialized production with a high degree of mechanization; it has high processing accuracy, high efficiency, and good airtightness, so it can be used to build gas tanks, oil tanks, and transformers.
In the future, the steel structure of Prefab House should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel), T-shaped steel and profiled steel plates, etc. The needs of large-span structures and super high-rise buildings.
(1) Light weight and high strength. Due to the use of steel as the load-bearing structure and new building materials as the enclosure structure, Prefab House generally uses steel structure to build residences that weigh about one-half of the weight of reinforced concrete residences, which reduces the weight of the house and reduces the cost of basic engineering. Since the building area occupied by the vertical force-bearing member is relatively small, the use area of the house can be increased. At the same time, because the steel structure residence adopts a large bay and large depth column network, it provides residents with a large space that can be flexibly separated, which can meet the different needs of users.
(2) The degree of industrialization is high and meets the requirements of industrialization. Most of the structural components of Prefab House are made in factories, which are easy to install and suitable for mass production. This has changed the traditional way of housing construction and realized the transformation from "building houses" to "manufacturing houses". Promoted the transformation of the housing industry from extensive to intensive, and at the same time promoted the development of productivity.

The beam-column joints of Prefab House are mainly connected by bolt welding. However, bolted joints are recommended for fabricated steel structures. The advantage of bolted connection (weld-free connection) is that the installation speed is fast and the construction quality is easier to control.
1. The construction period is short. Generally, the first floor of Prefab House can be built in three or four days, and it only takes one or two days. Steel structure residential systems are mostly manufactured in factories and installed on-site. The amount of on-site work is greatly reduced. Therefore, the construction period can be greatly shortened, and the noise and dust generated during the construction, as well as the consumption of on-site resources and various on-site expenses are correspondingly reduced. Compared with reinforced concrete structures, the construction period can generally be shortened by one-half, the investment benefits can be brought into play in advance, capital turnover can be accelerated, and construction costs can be reduced by 3%-5%.
2. Good seismic performance. Because the steel of Prefab House is an elastically deformable material, it can greatly improve the safety and reliability of the house. The steel structure has high strength, good ductility and light weight, which can greatly improve the mechanical performance of the structure, especially the seismic performance. Judging from the situation after the earthquake at home and abroad, the number of collapsed steel structure residential buildings is very small.
In line with the development direction of building energy efficiency. Prefab House uses steel as the frame and thermal insulation wallboard as the enclosure structure, which can replace clay bricks, reduce the amount of cement, sand, stone, and lime, and reduce the damage to non-renewable resources. On-site wet construction is reduced, and the construction environment is better. At the same time, steel can be recycled and reused, and the environmental pollution during construction and dismantling is small, and its energy saving index can reach more than 50%, which belongs to the green building system.
The application of steel structure in Prefab House has opened up a new application market for my country's steel industry. It can also drive the research and application of related new building materials.
Steel-finished house is generally a residential building constructed with factory-made, economical steel profiles as a supporting work and new lightweight, heat-conserving, heat-insulating and high-strength wall materials as a home. The industrialisation of the steel building house refers to the use of steel construction houses as the final product. Through socialized mass production, the process of investment, development, construction, construction and customer service of steel dwellings is centralised and unified into an overall organisational form. The industrialization of the steel building house is the development trend of the steel building house.

Agricultural steel building is a construction of steel materials and is one of the main types of construction. The structure consists mainly of steel bearings, steel columns, steel works and other components made of profile steel and steel plates and uses silanisation, pure manganese phosphation, washing and drying, galvanising and other rust and rust protection methods.
What is agricultural steel building?
What are the characteristics of people who opt for agricultural steel building?
What are the benefits of people opting for agricultural steel building?
The agricultural steel building is characterized by high strength, low weight, good overall stiffness and high deformation resistance. It is therefore particularly suitable for the construction of large-scale and ultra-high agricultural buildings; The material has a good homogeneity and isotrope, which is ideal for elasticity. The structure most closely corresponds to the basic assumptions of general technical mechanics; the material has good plasticity and toughness, can exhibit large deformations and can withstand dynamic loads well; construction time is short; the agricultural steel industry has a high degree of industrialisation and can be specialised in agricultural production.
1. agricultural steel building has good sealing performance
Since the welding design can be completely sealed, it can be air and water-tight to high pressure containers, large oil reservoirs, pressure pipes, etc. to be processed.
2. agricultural steel building is heat resistant and non-fire resistant
If the temperature is below 150oC, the properties of the steel change slightly. The steel structure is therefore suitable for hot workshops, but if the surface is exposed to heat radiation of approximately 150, it should be protected by a thermal insulation plate. If the temperature is between 300-C and 400-C, the strength and elasticity module of the steel material decreases significantly, and if the temperature is approximately 600-oC, the strength of the steel material is zero. In buildings with special fire protection requirements, the steel structure must be protected by refractory materials to improve fire resistance.
3. agricultural steel building has poor corrosion resistance
Especially in the vicinity of moist and corrosive media, it rust easily. In general, steel structures must be rusted, galvanized or painted and regularly maintained. Specific measures such as zinc-blockanode protection are required for offshore platform construction in seawater to protect corrosion.
4.The demolition of agricultural steelworks is not subject to any building protection and the steel can be recycled and reused.
The grid structure of the agricultural steel building has an adequate load, a high stiffness, a low weight, individual rods and a comfortable production and installation. In recent years, it has often been used in public and industrial buildings with large stretches and large columns. In the construction of agricultural steel buildings there are stainless steel sandwich plates, profile plates, lighting materials and other roof materials. It can be used not only for roof constructions, but also for floors, walls and special constructions.
Agricultural steel production plays an essential role in the current industrial production process. Qingdao Xinguangzheng Steel Structure Co., Ltd. has undertaken to offer the most suitable agricultural steel buildings at a reasonable price.

What is the purpose of isolation?
The purpose of isolation is to cut off the route of transmission in the infection chain,protect susceptible persons, and ultimately control or eliminate the source of infection.
Therefore, it is an important measure to prevent the spread of infectious diseases.
From a medical point of view, the goal of "isolation" is to prevent the spread of infection and ultimately eliminate or control the source of infection.
That is to prevent and limit the infectious factors of infected patients directly
or indirectly to susceptible persons,
or to those who may pass on such factors to others, and at the same time, enable infected patients to receive timely treatment under control and return to health as soon as possible.
Why choose container house?
In the construction field, it is called an assembled modular container house, also known as a container building or a container house.
It is a single room as a prefabricated unit.
