What are the advantages of single-structure industrial steel building?
What are the advantages of industrial steel building construction?
1. From the height:
The height of the drip level of a single-storey factory building is very important. Some factory buildings are 4-5 meters high, some are 6-7 meters, and some can be as high as 11-12 meters or higher. Generally, the taller the factory building, the more difficult it will be to build, and the more expensive the material costs will be.
2. From the external building structure:
Simple iron sheet: It is the simplest, a factory built with iron sheet relatively freely.
Steel structure workshop: The steel structure workshop is divided into steel structure or ordinary steel structure. Color steel structure is more than ordinary
much better.
Concrete structure: The wall is built with bricks and the roof is sealed with concrete. This structure has better safety and heat insulation than the previous two.
3. From the internal structure:
It is divided into those with corbels and those without corbels. Only the workshops with corbels can install cranes (also called cranes). This is an important part of industrial production. If there are machinery and equipment to install cranes, just Must have corbels to use.
industrial steel building has the characteristics of forming a large space for use, easily meeting the requirements of the production process, and convenient internal transportation organization, which is conducive to the placement of heavier production equipment and products, and can realize the industrialization of the production of plant building components and the mechanization of on-site construction. Therefore, industrial steel building has been widely used in industrial buildings such as metallurgy, machinery manufacturing, motor manufacturing, chemical and textile industries. Common structural forms of reinforced concrete single-story factory buildings include bent frame structure and rigid frame structure.
1. industrial steel building has good structural performance, light weight, high strength, and good seismic performance.
2. The steel used in industrial steel building is recyclable, which is more energy-efficient and environmentally friendly than masonry and concrete.
3. The industrial steel building is processed by the factory, so the quality of the industrial steel building is guaranteed.
4. industrial steel building materials have light weight and low base cost.
5. The on-site construction period of industrial steel building is short. There is basically no wet work on site, and no dust, sewage and other pollution will be generated.
6. The cross-section of structural components is small, the pillars are very thin, the walls are very thin, and the building area is large.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been committed to providing customers with reliable industrial steel buildings and perfect after-sales service so that customers can invest easily, use them with confidence, and have no worries.
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.
Agricultural steel building has low cost, short construction time, and less pollution. Therefore, it has become the best choice for new-style construction.
Structural parts: material, surface roughness, tolerance, surface treatment, straightness (or radian)
Connection: hole position deviation, bolt grade; welding method, welding standard, welding material; air tightness, non-destructive testing, liquid penetration testing, etc. are required
Overall structure: verticality, horizontality, etc.
Packaging: packaging materials, packaging methods
Storage: ambient temperature, ambient humidity
Transportation: loading and unloading, placing in vehicles, placing in containers, etc.
Fire protection technology. One of the most critical issues in agricultural steel building is the application of fire protection technology. The fire resistance rating of light steel structure houses is level 4. For light steel structure residential buildings, fire-resistant gypsum boards are pasted on both sides of the wall and the ceiling of the floor. For ordinary firewalls and household walls, 25.4 mm thick (1 inch) gypsum boards are used to protect them to meet the 1-hour fire protection requirement. The glass fiber filled between the wall columns and the floor joists also plays an active role in protecting fire and heat transfer.
Sound insulation technology. The agricultural steel building is filled with glass wool between the inner and outer walls and the floor joists, which effectively prevents the audio part transmitted through the air. For the impact sound transmitted through the solid, the following construction is performed: the partition wall is composed of two wall columns. There are two walls with intermediate spaces; for the small keel used to fix the gypsum board for the suspended ceiling, an elastic structure with small cut grooves is used to effectively reduce the transmission of structure-borne sound between floors.
If an agricultural steel building is damaged, we must immediately recognise and remedy the problem. The main factors of steel structural damage are:
(1) the structural viability of agricultural steel buildings is insufficient due to changes in load, overdue service and changes in rules and regulations;
2) The components of agricultural steelworks are deformed, twisted, damaged, deformed, etc., due to various accidents; which results in a weakening of the cross-section of the component, a twisting of the rod and a tearing of the connection;
(3) deformation, cracking and retardation of agricultural steel components or connections due to temperature differences;
4) The agricultural steel structure corrodes due to the erosion of chemical substances and electrochemical corrosion leads to a weakening of the cross-section of the steel structure;
5) Other include errors in design, production, construction and illegal use and operation during the service period.
There are three main technical reinforcement measures for agricultural steel construction:
1) Cross-section defences: Apply the element locally or over the entire length of the element with steel and connect it to a whole to carry the force together;
2) Change the calculation diagram: add additional supports, adjust load distribution, reduce cutting force level, force displacement of static indefinite structural support and reduce peak voltage;
3) Pre-tensioned cable method: use high-strength cables to strengthen the weak links of the structure or to improve the overall durability, stiffness and stability of the structure.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been developing agricultural steel buildings for many years, and is known as "the national brand leader in the Chinesesteel building industry". Therefore, customers can choose their products with confidence.

What are the advantages of using Steel building accessories to build houses?
What are the common Steel building accessories on the market?
Why do Steel building accessories need to be fireproofed?
1. The total weight of the building using Steel building accessories is light, which is about half of the concrete structure. At the same time, it can greatly reduce the foundation cost of the house.
2。 The construction speed of Steel building accessories is fast, and the construction period is at least one third shorter than that of the traditional residential system. A 1000 square meter building can be completed in only 20 days and five workers.
3. The house with Steel building accessories has good environmental protection effect. This is because the consumption of sand, stone and ash is greatly reduced during the construction of the residential buildings built by Steel building accessories. The materials used are mainly green, 100% recycled or degraded materials. When the buildings are demolished, most of the materials can be reused or degraded without causing garbage.
4. Steel building accessories is welcomed by everyone for its flexibility and abundance. Large bay design, indoor space can be divided by multiple schemes, which can meet the different needs of users.
5. The use of Steel building accessories meets the requirements of housing industrialization and sustainable development. The steel structure is suitable for mass production in the factory with a high degree of industrialization. It can integrate advanced finished products such as energy saving, waterproof, heat insulation, doors and windows, and apply them in a complete set, integrating design, production and construction, so as to improve the level of construction industry.
1. u-shaped bracket
The u-shaped bracket is also one of the important accessories of Steel building accessories. The bracket is used for the connection between the ground and the main material. In addition to the fixing function, the u-shaped bracket can also balance the overall bearing force.
2. Fishing rod bracket
The fishing rod bracket of the steel structure frame is a single-unit fixing device accessory, which is used for the initial fixing of the single-unit room.
The temperature resistance of steel is poor, and many of its properties change with the rise and fall of temperature. When the temperature reaches between 430-540℃, the yield point, tensile strength and elastic modulus of the steel will drop sharply, and the load-bearing capacity will be lost. Steel building accessories must be maintained with refractory materials.
Qingdao Xinguangzheng Steel Structure Co., Ltd., as a Chinese pioneer in producing Steel building accessories, can ensure the products’ quality and the after-sales service
Prefab house is a structure mainly made of steel, which is one of the main building structure types. The characteristics of steel are high strength, light weight, and high rigidity, so it is especially suitable for the construction of large-span, super-high and super-heavy buildings.
Compared with traditional concrete buildings, what are the advantages of Prefab house?
What are the advantages of Prefab house?
What is the installation process of Prefab house?
Compared with prefabricated concrete buildings, Prefab houses have the following advantages:
1. There is no on-site cast-in-place node, the installation speed is faster, and the construction quality is easier to be guaranteed;
2. The steel structure is a ductile material with better seismic performance;
3. Compared with concrete structure, steel structure has lighter weight and lower foundation cost;
4. The steel structure is a recyclable material, which is more green and environmentally friendly;
5. Well-designed steel structure prefabricated buildings are more economical than prefabricated concrete buildings.
6. The cross-section of beams and columns is smaller, and more usable area can be obtained.
Save heating costs
Prefab house is more energy-efficient and environmentally friendly when used in the home, such as a new type of thermal insulation layer that has a better thermal insulation effect. When a household measurement is implemented and the heating has the same temperature, the room temperature of the "assembled" space is higher. The head of household may consider lowering the heating temperature, saving heating costs and, at the same time, reducing energy consumption.
Save energy
Finished house is of great benefit for energy saving and environmental protection. Through factory production and on-site assembly, it can significantly reduce building protection and waste water, reduce building noise, reduce harmful gas and dust emissions and reduce building and management personnel on site.
The assembly procedure for the steel construction of the Prefab house: steel column assembly -Installation of the supports between the columns -temporary installation of the steel bearer -roof bearings, roof bearings -correction and fixing of the steel bearer -Installation of the maintenance structure.
1. Contamination protection: Avoid rain water entering the metal roof from the outside. Rainwater enters the metal roof mainly through overlapping joints or knots. In order to achieve the function of the centrifuge, it is necessary to use a sealing disc at the screw connection and to make a concealed fixation. Use sealants or welds on the top of the plate. Best use a long board to remove the overlap. Close water-tight treatment for bleeding.
2. Moisture resistant: Avoid condensation of water vapour in the soil and metal wax layer and drain the water vapour in the metal wax 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.
3. Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain points on the metal roof, the duration of use of the daylight should be aligned with the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
