Steel building accessories are constructed of steel materials. It is one of the main types of building structures. The structure consists mainly of steel bearings, steel columns, steel joints and other components made of profile steel and steel plates and uses rust removal and rust protection methods such as silylation, pure manganese phosphation, water washing and drying, galvanizing and so on.
Prefabricate and assemble Steel building accessories on the steel platform according to the installation sequence and process requirements to ensure the welding quality.
The spacing between the splicing joint of flange plate and web plate of section steel shall be greater than 200mm. The splicing length of flange plate shall not be less than 2 times of plate width; The web splicing width shall not be less than 300 mm and the length shall not be less than 600 mm.
In order to facilitate welding and ensure welding quality, the stiffener plates, connecting plates, base plates and cantilever beams (beams) on columns and beams shall be assembled and welded on the ground steel platform according to the dimensions of the construction drawing.
The Steel building accessories prefabricated on the steel platform shall not only be fabricated and assembled according to the construction drawings and specifications, but also consider the process of on-site installation and the change of installation size.
Some Steel building accessories users do not know that steel structures still need to be maintained and maintained. As a result, there is serious corrosion that users often can't find out, which makes steel products appear many unsafe hidden dangers, reduces the safety of Steel building accessories in use, and even affects normal use functions. It is recommended that the design unit not only put forward the painting requirements of the steel structure in the painting design description of the steel structure, but also put forward the maintenance and maintenance requirements of the Steel building accessories according to its use.
There are many ways to prevent Steel building accessories from rusting, and the following are usually used.
The steel structure is made of alloy steel that is not easy to rust
Chemical oxide layer protection method
Using metal coating protection method
Non-metallic coating protection law
In the later maintenance and maintenance process, non-metallic coating protection method is especially commonly used. The surface of the component is protected by paint and plastic, so that it does not contact the surrounding corrosive medium, so as to achieve the purpose of anti-corrosion. This method has good effect, low price, and has a wide range of paint varieties, a wide range of options, and strong applicability. It is not limited by the shape and size of the component. It can form a film with any shape on the surface of the component. The adhesion is firm. It can also follow the temperature change. The components are telescopic and easy to use. It is also possible to give the component a beautiful color.

Industrial steel building mainly refers to that the main load-bearing components are composed of steel. Including steel column, steel beam, steel structure foundation, steel roof truss (of course, the span of the plant is relatively large, and they are basically steel structure roof truss now), steel roof. Note that the wall of steel structure can also be maintained by brick wall.
What should be taken into account in the day-to-day maintenance of industrial steel buildings?
What are the arrangements for the planning of industrial steel buildings?
What should be taken into account when selecting industrial steel building?
After the installation of our industrial steel building, the owner is not allowed to change its structure privately, not to remove screws and other parts, and not to increase or reduce the partition wall. If you need to change a part, you need to negotiate with the manufacturer. It is up to the manufacturer to decide whether it can be changed. After approximately three years of use, the steel structure must be maintained with colour to give the building beauty and safety. industrial steel buildings are connected by steel construction components, so electrical devices such as wires should be insulated by cable channels in order to avoid accidents involving electric shocks.
The maintenance of industrial steel buildings is closely linked to the durability of the steel structure. That is why the industry pays enough attention to it. If you have problems with maintenance and maintenance, you should contact a professional steel construction manufacturer for help.
1. Insurance: Avoid rain water from the outside entering the metal roof of the industrial steel building. 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. Fire protection: The metal material does not burn in the event of fire and the flame does not penetrate the metal roof plate.
3. Wind pressure resistance: industrial steel building can withstand the maximum local wind pressure and the metal roof plate is not removed by negative wind pressure. The wind resistance depends on the strength of the metal roof plate and the fixing seat and the density of the fixing seat.
Sound protection: industrial steel building prevents sound transmission from the outside to the inside or from the inside to the outside. Fill the metal sheet with sound insulation material (mostly insulated cotton) and the sound insulation effect is expressed by the sound intensity difference on both sides of the metal sheet. The sound insulation effect depends on the density and thickness of the sound insulating agent. Note that sound insulating agents have different locking effects on sounds of different frequencies.

Prefab House refers to a building where parts and components produced in a factory are assembled and connected at the construction site. Steel structure prefabricated buildings refer to steel structure components produced in factories and assembled and connected at the construction site.
Different countries have different understandings and practices of the housing system, but Prefab House generally refers to the main project of the house. Different residential products are formed due to the selection of different structural materials, structural types and construction methods, and constitute a number of corresponding residential products ranging from design to The complete technology of construction. The steel structure residential building system uses the steel structure form as the basis for the classification of the building system and becomes a branch of the building system.
The material of Prefab House has good homogeneity and isotropy, which is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformations, and can well withstand dynamic loads; construction period is short ; It has a high degree of industrialization and can be used for specialized production with a high degree of mechanization; it has high processing accuracy, high efficiency, and good airtightness, so it can be used to build gas tanks, oil tanks, and transformers.
In the future, the steel structure of Prefab House should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel), T-shaped steel and profiled steel plates, etc. The needs of large-span structures and super high-rise buildings.
(1) Light weight and high strength. Due to the use of steel as the load-bearing structure and new building materials as the enclosure structure, Prefab House generally uses steel structure to build residences that weigh about one-half of the weight of reinforced concrete residences, which reduces the weight of the house and reduces the cost of basic engineering. Since the building area occupied by the vertical force-bearing member is relatively small, the use area of the house can be increased. At the same time, because the steel structure residence adopts a large bay and large depth column network, it provides residents with a large space that can be flexibly separated, which can meet the different needs of users.
(2) The degree of industrialization is high and meets the requirements of industrialization. Most of the structural components of Prefab House are made in factories, which are easy to install and suitable for mass production. This has changed the traditional way of housing construction and realized the transformation from "building houses" to "manufacturing houses". Promoted the transformation of the housing industry from extensive to intensive, and at the same time promoted the development of productivity.

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.
Nowadays, more and more industrial parks prefer to build workshop, warehouse, office and other buildings by steel structures. Why are steel structures so popular with the public? It is mainly due to the four excellent functions of steel structure "light, fast, good properties and economical".
1. Light: The steel structure has the characteristics of light weight and excellent stress function.
Steel has the smallest ratio of density to strength compared with concrete and wood. For example, the weight of steel roof trusses is only 30% or even 25% of the same concrete roof truss under the same load and strength conditions. The weight of the steel structure house is about 50% of the reinforced concrete house, but the usable area is about 4% higher than that of the reinforced concrete house.
The steel structure is prefabricated in the factory then bolts contacted installation on site. It has the characteristics of mass production of large pieces and high-level precision of finished products, which effectively shorten the construction period and reducing the cost to give high investment returen. Compared with the construction period of reinforced concrete structure engineering, the steel structure is only 1/3 to 1/2 of the reinforced concrete structure under the same conditions .
3. Good properties: The steel structure has good properties and high reliability.
Steel has uniform of texture, isotropy, large elastic modulus, good plasticity ,good resistance and is an ideal elastic plastic body. Therefore, the steel structure will not suddenly break due to occasional overloading or partial overloading, it can adapt to the oscillating load, and the calculation model can reflect the mechanical properties of the steel well, so the analysis is accurate and reliable.
The cost of steel structure is higher than concrete structure from the raw materials only, but the construction speed of steel structure is about 50% faster than concrete structure, which will save a lot of time and cost. The steel structure is more than 50% lighter than the overall weight of the concrete structure house, so that the cost of basic treatment and transportation will be reduced. Building is a systematic project includes many items, such as planning, manufacturing, transportation, installation, maintenance and management. Therefore, from the overall point of view, the steel structure is more cost saving.
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.
