A lot of work is needed to promote and improve the design specifications and construction technical standards of different types of structures, and to develop new types of lightweight insulation wall materials and the supporting issues of residential components. At the same time, it is necessary to widely publicize the advantages of the development of Residential steel building, so that more developers, designers and users can understand and understand steel structure housing.
What are the main forms of Residential steel building?
What are the structural characteristics of these Residential steel buildings?
What should I pay attention to when using Residential steel building?
Judging from the Residential steel building that has been built, the king has:
1) Thin-walled steel composite wall panel form;
2) Pure frame form;
3) Frame support form;
4) Form of steel-concrete combination;
5) Steel frame-concrete seismic wall form and so on.
The structural forms of Residential steel building have their own characteristics. Among them, the thin-walled steel composite wall panel is particularly suitable for finalized products. The Residential steel building system evolved from the wall panel structure, that is, the thin-walled steel column members are arranged at a distance of about 600mm. The vertical load-bearing structure and section steel have a support system to resist horizontal forces. The floor slab is arranged as a multi-rib support structure according to the position of the vertical section steel. Because the upper structure is a wall-like structure, the foundation is set as a strip foundation according to the force. The foundation requirements are not high.
The thin-walled steel composite wallboard residence is affected by the dense structure, and there are certain restrictions on the size of the partitions, door, door and window openings, and pick-out components.
The latter several forms of Residential steel building can meet the design requirements of multi-story residential buildings, but there is a common problem from the perspective of use, that is, the impact of the prominent beams and columns on the interior look and feel of the residence.
Compared with other buildings, Residential steel building has its particularity. Offices and workshops can use a relatively fixed column network, and the storey height is also higher. The space occupied by the beams and columns is suitable for people. The rules of the column network are conducive to the beams. Layout. On the contrary, the residence is a product with many changes. According to the requirements of the building, a regular column network is rarely arranged. The interior space of the house is relatively small and changes a lot, which is not conducive to the layout of the steel frame.
After seeing this and learning so much information about residential steel structures, I believe you must also want to order a Residential steel building. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Residential steel building you need. At the same time, their after-sales service is also very considerate.
Industrial steel building is a great invention. All components are prefabricated in the factory, and the site only needs to be assembled simply, thus greatly shortening the construction period. For a building of 6000 square meters, the basic installation can be completed in only 40 days.
What should I pay attention to when using Industrial steel building?
What are the reasons why Industrial steel building is used more and more widely?
What are the steps involved in the general process of Industrial steel building installation?
1. Industrial steel building construction has strict requirements for construction measurement. When the steel structure workshop stops the structural calculation, the mechanical model is very clear, and the size change has an obvious influence on the model. Therefore, during the manufacturing and installation stages, construction measurement is a more important issue. For example, inaccurate blanking will result in deformation of components; failure to be placed in place during installation will affect the load-bearing effect of the environmental characteristics of the construction site welding of steel structure workshops.
2. The steel of Industrial steel building has the characteristics of thermal expansion and contraction, and it is sensitive to weather, temperature and other conditions during the installation process. Industrial steel building welding has its own special technical requirements. In practice, when natural conditions cannot meet the work requirements, manual measures are often taken to create conditions for construction, such as preheating of welding rods and preheating and heating of steel plates. If the size of the steel structure factory building changes greatly during the construction process, the temperature is too high or too low will affect the accuracy of the device.
3. The Industrial steel building is easy to rust and has poor fire resistance, so it needs to be painted and maintained. Paint the steel structure factory building fireproof coating on the exterior of the Industrial steel building to play the role of fire protection and heat insulation maintenance, to prevent the steel from rapidly heating up in the fire and reducing its strength, and to prevent the steel structure factory building from losing its support ability and causing the building to collapse.
The grid structure of Industrial steel building has the advantages of reasonable stress, large stiffness, light weight, single member and convenient fabrication and installation. In recent years, it has been widely used in public and industrial buildings with large span and large column network. It can be used not only for roof structure, but also for floors, walls and special structures.
1. The main structure hoisting of Industrial steel building,
2. Secondary structure installation of Industrial steel building,
3. Installation of roof panel and insulation layer of Industrial steel building,
4. Wall maintenance and installation,
5. Finally, the detailed structure of Industrial steel building.
After reading this, have you also had the idea of ordering Industrial steel buildings. At Qingdao Xinguangzheng Steel Structure Co., Ltd., you can get the best quality Industrial steel buildings and the most intimate after-sales service.
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.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has worked on the production of Prefab Houses for several years. You can find the best Prefab House in this company.
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.
Knowing this, do you also need to order a Prefab House? Qingdao Xinguangzheng Steel Structure Co., Ltd. is committed to providing various Prefab Houses with high quality for all customers from all over the world.

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.
Color steel insulation sandwich panel is the basic materials for steel structure buildings, which is suitable for steel structure industrial plant. It is composed of two layers of formed metal panel and directly foaming, curing molding polymer heat insulation inner core. Color steel insulation sandwich panel commonly used insulation materials are: glass wool, polystyrene(EPS), polyurethane(PU), Rock wool and other insulation materials.
Then, what's the difference between these three insulation materials?
1) Glass wool sandwich panel. Glass wool is a good inorganic thermal insulation material, glass wool is obviously characterized by good fire resistance, flame retardant and moisture absorption, and its price is cheap. The thermal conductivity of the glass wool sandwich board is not greater than 0.038 W/(m2•K).
2) Polystyrene (EPS) sandwich panel. Polystyrene is a polystyrene resin as the main raw material, through the foaming agent foaming and made of internal with numerous closed micropores. Its insulation effect is good, the price is cheap, the strength is slightly poor. Polystyrene (EPS) sandwich board, thermal conductivity is not greater than 0.038W/(m2•K).
3) Polyurethane(PU)sandwich panel. The thermal conductivity of polyurethane sandwich board is no more than 0.033 W/(m2•K), with good thermal insulation performance, good water resistance, good thermal insulation effect, high strength, foam can be made into any shape, suitable for site construction, but the price is expensive.
To meet different thermal insulation requirements, consider the thermal conductivity of the steel structure material and the thickness of the insulation layer. The thermal conductivity of commonly used steel structure insulation materials is as follows: polyurethane foam> polystyrene foam >glass wool > rock wool.

The light steel structure of commercial steel building is a structure composed of steel materials, and each component or part is connected by welding, bolts or rivets.
commercial steel building is mainly used for low-rise or multi-storey buildings: the prefabricated wall panels are transported to the construction site by special vehicles, hoisted by cranes, connected with the foundation by anchor bolts and connectors, and the wall panels are connected by screws and connectors, and then the light steel floor is installed. The light steel floor is composed of floor beams, profiled steel plates Steel wire mesh and concrete. The construction of the main structure can be completed by constructing the upper floor according to the construction method of one floor and finally installing the roof. The system is applicable to buildings with 6 floors and below. It has the advantages of high assembly rate, short construction cycle, earthquake resistance and typhoon resistance, thermal insulation, large use area in the sleeve, no exposed beams and columns, and recyclable materials.
1. The construction period is short. The construction period of commercial steel building can be shortened by more than 50%;
2. The project quality is stable. The quality of parts and components produced in commercial steel building factory is more stable, which solves many common quality problems of on-site construction technology and human errors in on-site construction, and ensures the project quality;
3. Energy saving and environmental protection, less construction pollution. commercial steel building adopts energy-saving technology, which greatly improves the performance of house thermal insulation and sound insulation, and improves the living comfort of the building. According to statistics, the prefabricated construction method can save about 50% water, 70% wood and 70% construction waste;
4. Integrated decoration, which is carried out simultaneously with architecture, structure and electromechanical design. commercial steel building completes the pre functional conditions, pipeline installation, wall decoration and component installation in place at one time, which not only ensures the decoration quality, but also avoids the repeated waste and secondary pollution of secondary decoration.
1. Variability
The construction quality problems of commercial steel building will continue to evolve and change with external changes and the extension of time, and quality defects will gradually manifest. For example, the welds of steel components cause cracks in the welds that did not originally have cracks due to changes in stress: delayed cracks can occur due to the activity of hydrogen in the welds after welding. In addition, if the component is subjected to long-term overload, the steel component will be bent and deformed under the arch, which will cause hidden dangers.
2. Frequent
When faced with the relatively unfamiliar construction and construction techniques of steel structures, managers and technicians engaged in construction must be very careful and trained before they can take up their posts.
