How to remove the rust spots on the surface of Steel building accessories?
For Steel building accessories that have been used for a period of time, there are inevitably some attachments on the surface, such as rust, dirt, dust, old paint film, etc. Before painting the surface of Steel building accessories, if these attachments are not completely removed, although they can be temporarily covered after painting, they play a role of isolation, which makes the coating and the component substrate bond If the strength is severely reduced, the paint film will fall off prematurely, which will eventually reduce the corrosion resistance of the surface coating and fail to play the protective role of the coating. Therefore, before painting the surface of the component, the attachments on the surface of Steel building accessories should be thoroughly cleaned.
In order to improve the quality of rust removal and work efficiency. To improve the working conditions of construction workers, the current Steel building accessories derusting work has adopted a large number of wind-driven or electric small equipment. The main rust removal methods using equipment are:
(1) Angle grinder: This small pneumatic equipment is mainly used to clean flat areas. It can use sandpaper, grinding wheels and wire brushes as needed.
(2) Needle Bundle Derusting Machine: This kind of small pneumatic equipment is generally equipped with 30-40 needle bundles, which can be adjusted with different working surfaces, which are mainly suitable for curved, narrow, uneven and cracked places.
(3) Single-head cold air gun: This small pneumatic equipment is also called zinc knocking. It uses the impact of the knocking head to remove rust. The diameter of the shovel head is generally 25-40mm, and it can impact 1000 to 6000 times per minute. Suitable for relatively narrow places.
1. Two-hole connection accessories
One of the main accessories of Steel building accessories is the double-hole connection accessory, which is mainly used to connect with the corners. The corners on both sides of the right-angle connection can reduce the pressure on the alloy. At the same time, the recesses of the building materials can be based on the aluminum alloy frame.
2. Single hole connector
Steel building accessories also has an important accessory, the single-hole connector, which has a completely different function from the double-pipe connector. It is mainly used for the affinity connection between the aluminum alloy frame and the ground in the ground installation. Therefore, the single-hole connector has The role of anchor bolts.
The Steel building accessories have been widely used in daily life and industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Steel building accessories for their customers.
How much do you know about the Agricultural steel building?
When you consider the building materials used in a new construction project, you will feel uneasy. In fact, by choosing steel (rather than wood, stone, brick, etc.), you have already taken the first step to ensure that the completed project produces the best results. Steel is attractive because of its unparalleled strength-to-weight ratio, ductility, price, aesthetics, and consistency of composition from the beginning. There are more and more applications of agricultural steel building in agricultural production. Let’s take a look below.

What is the significance of the development of agricultural steel building?
The economic benefits of the development of agricultural steel building are good. First of all, the entire building does not require beams and bars, and the cost is only two-thirds of the light steel structure, and the larger the span, the lower the cost. In addition, the construction of agricultural steel building can greatly shorten the construction period, and the daily construction area can reach 1000m, which greatly saves the construction of machinery and labor costs.
The social effect of the development of agricultural steel building is significant. The construction period of modern large-scale projects is closely linked to economic benefits. Because we have adopted agricultural steel building development, the construction of the project is completed ahead of schedule, which creates good conditions for agricultural production units to put into use in advance, and the social effect is significant.
How to set the power supply in agricultural steel building?
1. The main distribution box in the agricultural steel building should be installed near the power source, and the distribution box should be installed near the electrical equipment or power-using area.
2. The distribution box in the agricultural steel building is made of iron plate.
3. The distribution box in the agricultural steel building should be equipped with a working neutral terminal board and a protective neutral terminal board.
4. The metal box, metal base and shell must be protected and connected to zero. The distribution box must be protected from rain and moisture. There must be a secondary leakage protector in the distribution box, and each electrical equipment should have its own dedicated switch box, which must implement "one machine, one switch, one leakage, one box", equipment and lighting are disconnected, all power distribution The boxes are all equipped with doors and locks, and a dedicated person is responsible for keeping them, and a regular inspection and maintenance system is implemented.

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.
The main structure of the commercial steel building can be installed simultaneously with the wall panel. The main structure and the wall panel are fixed by embedded parts and connectors, which is convenient for installation. It only needs to be hoisted in place, connected and fixed, and the three links of joint treatment are not required. No need for secondary grouting, and has the advantages of short construction period, high assembly rate, good integrity, and good wind pressure resistance.
(1) When the sides of the upper and lower columns without ear plates are symmetrically welded to 1/3 of the plate thickness by two welders on both sides, cut off the ear plates.
(2) Then two welders are symmetrically welded on both sides to 1/3 of the plate thickness on the side where the ear plate is cut off.
(3) Two welders will be responsible for the welding of two adjacent sides.
(4) The joints of the weld bead between every two layers should be staggered with each other, and the weld bead joints welded by two welders should also pay attention to the stagger of each layer. Pay attention to the temperature between the layers during the welding process.
(5) Welding process parameters:
CO2 gas shielded welding: wire diameter Φ1.2mm, current 280~320A, welding speed 350~450mm/min
Extending length of welding wire: about 20mm, gas flow rate 25~80L/min,
Voltage 29~34V, interlayer temperature 120~150℃
We must prefabricate and assemble commercial steel building steel components on the steel platform in accordance with the installation sequence and process requirements, and ensure the quality of welding production.
The spacing between the splicing seam of the splicing flange plate and the splicing seam of the web plate of the section steel should be greater than 200 mm. The splicing length of the flange plate shall not be less than 2 times the plate width; the splicing width of the web shall not be less than 300 mm, and the length shall not be less than 600 mm.
In order to facilitate the welding of commercial steel building and ensure the welding quality, try to weld the reinforcement plates, connecting plates, backing plates, and overhanging beams (beams) on the columns and beams on the ground steel platform according to the dimensions of the construction drawings.
In addition to the fabrication and assembly of steel components prefabricated on the steel platform according to the construction drawings and specifications, the process and installation dimensions of the commercial steel building on-site installation should also be considered.
The construction of commercial steel building has trained a new generation of construction and installation industrial workers. Factory production and mechanized installation avoid the high dependence of the traditional construction industry on labor, moderately reduce the impact of high labor costs brought on by the aging of the global population on the development of the industry, and predictably cultivate a new generation of construction and installation industry workers. It is of far-reaching significance to the sustainable development of the construction industry.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has focused on the development and production of commercial steel buildings for several years. And it commits to provide perfect service for every customer from all over the world.
At present, the construction technology of large-space steel structure construction has made great progress, and the "folding and unfolding" construction technology is a construction method that fully expresses the changes in the construction process of large-span space construction. He turned a large structure into a movable mechanism; the industrial steel building is so popular nowadays mainly because its advantages surpass the previous buildings.
What is the meaning of industrial steel building?
What should I pay attention to when installing steel columns in industrial steel building?
What should be paid attention to when constructing industrial steel building?
The use of steel construction in industrial steel building has the advantages of shorter construction period, higher application rate, sensitive plan, column spacing and large span. As far as the owner is concerned, industrial steel building can shorten the investment construction period and work quickly. The components can be disassembled and re-applied, which promotes environmental protection and saves resources. Therefore, the application in modern industrial design is becoming more and more common.
(1) Due to the heavy weight and long length of the steel column, the industrial steel building cannot be manufactured and transported at one time. Therefore, the method of segmented manufacturing and on-site assembly as a whole is used for hoisting. It is planned to divide the steel column into two sections. The steel column is transported to the site in two sections, the lower lattice part and the upper H-shaped steel column. The weight of the steel column is about 6 tons, and the height in place is about 17 meters. A 50-ton truck crane can meet the hoisting needs, supplemented by a 25-ton truck crane for hoisting.
(2) The hoisting adopts single-machine rotary hoisting. Before lifting, padded wooden squares at the position of the steel column foot plate to prevent the steel column from damaging the foot plate during the lifting process. When the steel column is hoisted, the crane should lift the hook while turning the arm to make the steel column vertically off the ground and put the column into the mouth of the cup.
Ventilation: air exchange in indoor and outdoor areas. Put air vents on the metal roof.
Moisture resistant: Avoid condensation of water vapour in the lower layer of the metal roof and metal roof layer and drain the water vapour in the metal ceiling layer. The solution is to fill the metal roof with thermal insulation cotton, place a waterproof membrane on the metal floor plate and have ventilated knots on the metal roof.
Carrying: construction load, rain, dust, snow pressure, maintenance load. The load bearing capacity of the metal roof depends on the cross-section characteristics of the plate type, the strength and thickness of the material, the power transfer method and the distance of the horses (sub-horses).
Lightning protection: Take the lightning to the ground to prevent the lightning from penetrating the metal roof and entering the room.

Industrial steel building has a wide range of applications and can be used in factories, warehouses, office buildings, stadiums, hangars, etc. to be used. It is suitable not only for single-storey large-space buildings, but also for the construction of multi-storey or high-rise buildings.
What are the architectural features of industrial steel building?
What is the reason why more and more people are choosing industrial steel building?
What types of construction are available for industrial steel buildings?
Insulation: Avoid heat transfer on both sides of the metal roof to ensure that the ambient air temperature is stable. The thermal protection function is realized by filling thermal protection materials (usually used glass wool and stone wool) under the metal roof plate. The heat conservation effect is expressed by the U-value and the unit is W/M2K. The thermal insulation performance is determined by the following factors: raw material, density and thickness of the thermal insulation cotton; the humidity of the thermal insulation wall, the method of connecting the metal roof plate and the underlying structure (to prevent the phenomenon of the "cold bridge"), the repeated ability of the metal coating to heat radiation.
Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain positions on the metal roof, the duration of the daylight should be adjusted to the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
Beautiful: The metal roof of the industrial steel building has a good texture and a pleasant color.
Check the heat expansion and contraction: check the contraction shift and direction of the metal roof plate. Make sure that in areas with high temperature differences the metal roof plate is not damaged by heat expansion and contraction.
Anti-avalanche: install snow barriers on the metal roof in snow-covered areas to prevent a sudden fall of snow.
Anti-ice caps: industrial steel building can prevent rain and snow from forming ice caps on the mould.
The frame of the industrial steel building is the main structure of the system frame. It is a flat structure consisting of columns and frames. All horizontal water loads and most vertical loads are transferred to the foundation via the plant frame. In industrial buildings, the industrial steel building frame has the following three most common types of construction;
1. The single-storey steel structure factory building frame is a single-storey frame formed from the stacked column of the factory building and the frames anchored to the top of the column (the column top can be called the system bent when the column top is foldable).
2. A rigid one-storey frame, a one-storey frame formed by a rigid connection of columns with an equal or gradual cross-section and frames on the top of the column.
3. Multi-layered frame, a multi-layered frame formed by joining columns and floor supports (or specialist works) and roof supports or roof supports.
Having learned so much about industrial steel building, it is also a difficult problem to select from many manufacturers the one with high quality and low price. Qingdao Xinguangzheng Steel Structure Co., Ltd. has been a Chinese pioneer in industrial steel building for several years.
