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.

What are the main Steel building accessories?
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.

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.

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.
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.
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.

What are the reasons why people choose Residential steel building?
What should the choice of Residential steel building structural system look like?
What is the framework system used by Residential steel building?
1. Residential steel building energy saving and environmental protection
The main body of the Residential steel building is steel components, and the wall material is thermal insulation mortar, which not only meets the requirements for energy saving, but also can be recycled. It is a green and environmentally friendly recycling building that meets the requirements of sustainable development. The thermal resistance can reach a brick wall thickness of about 1m. At present, the global population is large and energy consumption is large, and the promotion and application of steel structure housing is the final choice.
2. Residential steel building's pipe network line layout is convenient
In residential buildings, there are many lines of professional plumbing and electricity pipe network, which will reduce the effective use area in traditional buildings. In Residential steel building, there are many holes or holes in beams and columns, which is easy to form a cavity for wiring layout. Moreover, the beam can be artificially made into a honeycomb shape, which is convenient for line layout, which not only saves the net height of the building, but also increases the use area.
According to engineering practice, the commonly used Residential steel building structure system can be selected with reference to the following scope:
The 4th to 6th floors are the steel frame system, the steel frame-support system, and the steel frame-shear wall system; the 7th to 12th floors are the steel frame-concrete core tube (shear wall) system.
The section form of steel components should be hot-rolled H-section steel, high-frequency welded H-section steel and steel tube concrete.
Light steel frame system
The light steel frame system is a load-bearing frame composed of hot-rolled H-shaped steel (or I-beam), high-frequency welded H-shaped and cold-formed square pipes, and a steel structure residence with composite curtain walls or infill walls as the enclosure structure system.
The wall panels in the picture collection are made in the factory with fly ash as the filler, sulfoaluminate as the cement, polystyrene foam (EPS) as the core material, and glass fiber mesh as the reinforcement material.
