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 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.
Qingdao Xinguangzheng Steel Structure Co., Ltd. strives to provide top-quality residential steel buildings with reasonable prices, efficient production time, and the most professional customer service.
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.
Industrial steel building mainly means that the main load-bearing components are composed of steel. Including steel pillars, steel beams, steel structure foundations, steel roof trusses (of course, the span of the factory building is relatively large, and it is basically steel structure roof trusses now), steel roof, note that steel structure walls can also be surrounded by brick walls.
What are the characteristics of Industrial steel building?
What are the industrial characteristics of Industrial steel building?
Why do we have to carry out daily maintenance on Industrial steel buildings?
The characteristics of the steel construction workshop are:
1. Industrial steel building is light, high-strength and has a large span width.
2.The construction time of industrial steelworks is short, reducing investment costs accordingly.
3. Industrial steel buildings have poor fire resistance and corrosion resistance and steel structures should not be used in areas with low temperatures.
4. Industrial steel building is easy to move and recycle without contamination.
The roofs of flat buildings are mostly inclined roofs, so that the roof construction essentially uses a triangular roof chair system made of cold-formed steel components. The light steel components form a very strong structure after sealing the building plates and plasterboard plates. "Plate-rib structural system", the industrial steel structure of this structure has a stronger earthquake resistance and resistance to horizontal loads and is suitable for areas with earthquake intensities above 8-degree.
The Industrial steel building has a low weight, a high strength, a good overall stiffness and a strong deformability. The building weighs only a fifth of the brick concrete construction and holds a hurricane of 70 meters per second so that life and property can be effectively protected.
The housing structure of the Industrial steel building consists entirely of cold-formed thin-walled steel component systems. The steel frame consists of a high-strength, cold-rolled, fire-soaked super-corrosion protection sheet which effectively avoids the influence of steel sheet corrosion during construction and use and increases the durability of light steel components. The durability of the structure can reach 100 years.
Industrial steel buildings must be regularly cleaned and maintained. Under normal circumstances, it must be inspected and maintained once a year. When cleaning the outer wall of the Industrial steel building, you must be careful not to contaminate anything. Do not use steel wire balls, brushes and other abrasive cleaning agents. If you use clean water, you should rinse from top to bottom. The branches, leaves and similar objects on the Industrial steel building should be cleaned in time to avoid unnecessary problems due to the delay. If the surface of the metal plate for industrial steelmaking is damaged, it should be repaired in time to prevent the surface of the metal plate from corroding by sun and rain. If necessary, use all coated high-elastic nanomaterials to protect the metal roof plate, act effectively in thermal insulation and sealing and save energy for room climate.
Seeing this, do you also want to order a Industrial steel building? If necessary, you can contact Qingdao Xinguangzheng Steel Structure Co., Ltd. they will provide the Industrial steel building of the best quality.
Steel structures are a new type of construction system that offers the benefits of low weight, easy installation, short construction time, good seismic performance, fast investment recovery and low environmental pollution. It is therefore generally preferred by all parties in the industry. Under the call for green construction, energy saving, environmental protection and resource recycling, steel structures have gradually become widespread in agricultural steel building and the scale of the steel construction industry has expanded further.
