The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. The steel structure is easy to rust. Generally, the Steel building accessories shall be derusted, galvanized or coated, and shall be maintained regularly.
For maintenance personnel, the daily maintenance of Steel building accessories should first be the maintenance of the surface coating of the components. The maintenance of the coating directly affects the service life of the steel structure. Therefore, to do a good job in daily maintenance, you should start with the following points:
1. The surface of the steel structure must be kept clean and dry, and the places where the steel structure is easy to accumulate dust (such as the steel column foot and the gusset plate) should be cleaned regularly.
2. Regularly check the integrity of the protective coating of Steel building accessories. If one of the following occurs, it should be maintained in time:
1) It is found that the area of the coating surface loses its luster to 90%;
2) The area of roughness, weathering and dry cracking of the coating surface reaches 25%;
3) The paint film bulges in the coating and the slightly rusted area of the components reaches 40%;
3. The steel structure parts affected by high temperature and high temperature should be equipped with protective plates to protect the coating from high temperature damage.
4. Try to avoid contact of Steel building accessories with corrosive substances, and clean up those that have been in contact.
1. According to the principles of production applicability, reliable performance, safe use, and convenient operation, a variety of Steel building accessories should be selected reasonably.
2. The inspection and measurement equipment should ensure the unity, accuracy and reliability of the value transmission. Various measuring tools such as steel tape, board, square, level, spring force gauge and so on used in the construction shall be verified before storage to ensure that the measuring instruments entering the construction site are qualified. The tools used in the construction shall be checked regularly . Ensure that each tool always meets the measurement accuracy requirements in the same project.
Steel building accessories must weld the cracks between the two drill holes. During welding, the edges of the cracks can be gas-cut into different types of grooves according to the thickness of the component to ensure the quality of the welding. When the thickness is less than 6mm, use 1 shape (that is, without beveling); when the thickness is greater than 6mm and less than 14mm, use the V-shaped bevel; when the thickness is greater than 14mm, you need to use the X-shaped bevel.
As technology advances, Steel building accessories are increasingly used in everyday life. Qingdao Xinguangzheng Steel Structure Co., Ltd. is known for high precision Steel building accessories. And you can connect them.
Introduction of Qingdao Jiaodong International Steel Structure Building Airport
Qingdao Jiaodong International Airport (comprehensive transportation center and parking building) project is constructed by open cut method. The buried depth of the structure bottom is about 2.5m, and the wall wrapping surface is about 3.5m * 0.85m.
The column is made of Φ 850 * 25 / φ 700 * 16 straight seam concrete-filled steel tubular column, and the upper and lower columns are welded by variable diameter (φ 850 ~ φ 700). The total height is about 30 meters, and the total weight is about 20 tons. It is transported to the construction site in 17m + 13m sections. Each steel pipe column is made of 25 mm or 16 mm thick steel plate.
Factory processing assembly with an error of ± 2mm to meet the requirements, the construction site using a 250t crane for installation.
Prefab House refers to the use of industrial production methods to build houses, that is, the stairs, exterior walls, balconies, air-conditioning panels, etc. of the house are all prefabricated in the factory outside the construction site, and then shipped to the construction site for "assembly", and the interior of the house will be refined at one time. Handed over after renovation. That is, the huge external walls, stairs, and balconies from the factory are "assembled" on the construction site into houses and buildings.
What are the advantages of a Prefab House?
What are the structural types of Prefab Houses?
What should we be careful about when selecting a Prefab House?
1. Safe and reliable
The Prefab House with steel as the main building material has a high capacity per volume unit, is more stable and solid than the traditional brick and brick concrete technology, has a better seismic performance, wind resistance, water density and refractory performance and also has thermal insulation and sound protection functions. Steel has good ductility and can better use the energy brought in by earthquakes, so it has good seismic performance and a high structural security t hat guarantees the safety of stay.
2. Easy construction and short construction time
All components are prefabricated in the factory and only have to be installed on site, which greatly shortens the construction cycle. A 6000-square-metre-long building can basically be installed in 40 days.
1. Structural system
The structure of the Prefab House can be divided into: steel frame system, steel frame support system, steel frame-core tube system, steel frame-module-core tube system and steel frame-shear-wall system. With the continuous development of the technology, newer steel construction systems will also appear.
2. Peripheral protection system
The outer protective system of the Prefab House can be divided into blocks, plates, cans and other types.
3. Internal system
Traditional construction has many disadvantages. For example, the traditional rough decoration method does not separate the interior system and the structural system, which makes it difficult to adapt to the modern development of the housing industry; the house technology lines are not separated and the water and power lines are buried in the support layer, which the "century residence" cannot realize." The waste of social resources is serious.
1.The costs are relatively higher than in the traditional Prefab House made of brick concrete and concrete.
2. The steel structure of the Prefab House, with its unique steel structure, walls, roofs and other materials, as well as the standardized and final internal distribution and support facilities, is difficult to adapt to the habits of people "arbitrarily handling the house".
3. Corrosion of steel: Al-galvanized steel must be used for maximum corrosion protection and the main steel structure can reach fifty years.
4. There are many requirements for new materials. The structure of steel houses is equipped with materials such as thermal insulation and heat protection, usually using new lightweight materials.
Prefab Houses produced by Qingdao Xinguangzheng Steel Structure Co., Ltd. feature attractive appearance, excellent performance, user-friendly operation, easy maintenance, and internationally advanced performance indicators, and are exported to more than 10 countries and regions.

Industrial steel building is easy to move and recycle without pollution. These are stronger than traditional workshops, and the walls of the steel structure workshops can also be filled with bricks, which are completely load-bearing. All future plant constructions will be steel structure plants. Here we are going to introduce the steps of installing Industrial steel building.
What are the raw materials used in industrial steel building?
What is the main installation process of industrial steel building?
What is the production and installation process of industrial steel building?
In addition to iron and carbon, the raw materials of industrial steel building also contain other elements. Divided into permanent elements; occasional elements; hidden elements and alloying elements. The common elements are manganese, silicon, sulfur, and phosphorus. Incidental elements are due to the different origins of ore (there are intergrowth ore mixed with iron) and scrap steel as raw materials, such as copper, titanium, vanadium, rare earth elements, etc., are brought into steel during smelting and process operations. The cryptic elements refer to non-metal elements with a small atomic radius, such as oxygen and hydrogen. Alloying elements refer to elements specially added to change the composition, such as chromium, nickel, tungsten, molybdenum, vanadium, etc.
Carbon steel (referred to as carbon steel) is an iron-carbon alloy with a carbon content of more than 0.0218% and less than 2.11%. Because carbon steel has good mechanical properties and process properties, and is large in output and low in price, it is a metal material that is widely used in mechanical engineering. However, carbon steel also has some shortcomings, such as low hardening energy, poor temper softening resistance, and low yield ratio. The strength potential of carbon steel cannot be fully utilized even after heat treatment. In order to meet the continuous development of modern industry and science and technology, alloy steel was developed.
Foundation → production and installation foundation is divided into (foundation ground survey → foundation excavation → embedded screws → foundation casting → later foundation grouting → outdoor water dispersion → outdoor drainage ditch (some factory design indoor drainage ditch or cable ditch suggestion Completed simultaneously with installation)→Enclosure masonry→tiling tiles, etc.)
The production and installation are divided into (processing production→component painting→structural pre-assembly→steel component hoisting→main structure adjustment→purlin installation→door and window column installation→gutter downpipe installation→steel component painting (some are fireproof, some are Anti-corrosion, according to design requirements) → roof panel (some with steel mesh, some with insulation layer, completed at the same time) → wall panel installation → door and window installation → water supply and drainage installation → electrical equipment installation)

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.
