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.
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.
Knowing this, do you also want to order a commercial steel building? Qingdao Xinguangzheng Steel Structure Co., Ltd., which has been a Chinese pioneer in commercial steel building for many years. Their skilled staff can use the best solution for anything, particularly when a custom product is required.
The development of residential steel building conforms to the industrial technology policy of protecting arable land and saving energy, and is also one of the production methods for realizing residential industrialization. The development of steel structure housing is the general trend.
What is the layout of the residential steel building?
What issues should be paid attention to when designing residential steel building?
Why pay attention to the design of residential steel building?
residential steel building’s column grid layout should be regular, and it is advisable to use residential units or sleeves as the unit to achieve modularity. The modular flat connection, wrong connection and symmetrical concave (convex) connection and other splicing adapt to changes in the overall layout .
When the residential steel building module adopts small column net, it should be combined with the floor and pipeline design; when the module adopts large column net, the facility pipeline should be designed as a fixed-positioned tube bundle, and the electrical and communication lines can be along the cavity and skirting of the partition wall. , Mirror hanging line or top line arrangement.
The kitchen and bathroom are located close to the concrete core tube or concrete shear wall, and avoid steel structure load-bearing components to facilitate the fire prevention and anti-corrosion treatment of steel components.
Vertical pipelines are centrally arranged in pipeline wells or pipeline walls, or installed on site using factory prefabricated tube bundles.
The toilet is drained on the same floor. Use a double pipe system for centralized heating, and use a temperature control valve and a heat meter. Use the equipotential characteristics of the steel structure to make a natural ground connection.
residential steel building should be dominated by construction and design, and other professions should interact closely with each other. In addition to following the general principles of residential building design, residential steel building must also focus on solving:
(1) How to make use of the advantages of steel structure? The beam span can be enlarged, the bays can be more flexible, and more space can be created for residents. But how to avoid the flatness and monotonous facade of the building caused by the steel structure.
(2) It is necessary to solve the fire protection and anti-corrosion problems of steel structure residential buildings. Especially in rainy areas, the quality of anti-corrosion and anti-rust work directly affects the promotion of steel structure housing.
The cost of residential steel building is the most concerned issue of real estate developers. Steel structure residences should be positioned in middle and high-end residences. Steel structure residences are a systematic project. Management and coordination should be strengthened from design, manufacturing, transportation, installation, maintenance and management, so as to reduce costs and improve overall economic benefits. the goal of.

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. A lightweight board. Special adhesive is used to bond the plate and the light steel frame, and between the plate and the plate. To prevent thermal bridges using double-layer plates.

As the strategic decision to develop energy-saving and land-saving housing and construct a conservation-oriented society is further deepened and housing industrialization has become a new growth point for the world’s economic development, the development of residential steel building will be the only way for housing industrialization.
1. residential steel building's structural system is diversified
Many structural systems that can be used for steel structure residences have been developed, steel frame structure, steel frame-support structure, frame-tube structure (steel frame, concrete internal simplified), frame-shear wall structure (shear wall can be steel plate, concrete Or concrete with built-in steel support), light steel structure and staggered truss structure system can all be used as the structural selection of residential steel building.
2. The project cost of residential steel building is slightly higher than that of concrete or equivalent
The cost of steel structure material is higher than that of concrete, but its construction period is short, the use area is large, and the number of floors can be increased under the same conditions. The project cost of residential steel building is slightly higher or equivalent to concrete, and the actual economic benefits are significant, making residential steel building It has become the first choice for high quality and low price, and the best choice for replacing masonry structure houses in the future.
residential steel building has a high technological content. The structure itself is often the architectural expression. The performance and craftsmanship of the steel structure is not only a necessary means to realize the image conception, but also has a significant impact on the architectural image, which determines that the structural conception is the success of the image conception. The key is whether or not. The progress of science and technology and the change of aesthetics will inevitably make steel structure buildings continue to expand their expression vocabulary and seek development. residential steel building sets aside the elements of style, starts from structural rationalism, and absorbs the essence from modern and traditional styles. In the future, it will be possible to create high-quality steel structure buildings with organic integration of technology and art.
The residential steel building of the design structure and the stability calculation of components must cooperate with each other to make them consistent. The consistency between structural calculation and structural design has always been a problem that everyone pays attention to in structural design. For the joint connection requiring to transfer bending moment and not, sufficient stiffness and flexibility shall be given to it respectively, and the eccentricity of members shall be minimized for frame joints, which are often considered by designers when dealing with structural details. However, when it comes to stability, there are often structural requirements or special considerations different from strength. For example, in terms of flexural strength of simply supported beams, the requirement for fixed hinge support is only to prevent displacement and allow rotation in the plane. However, the above requirements are not enough when dealing with the overall stability of the beam. The support shall also be able to prevent the beam from twisting around the longitudinal axis, and allow the beam to rotate in the horizontal plane and the beam end section to warp freely, so as to meet the boundary conditions adopted for stability analysis.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been committed to providing customers with residential 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.
