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.
What is the purpose of isolation?
The purpose of isolation is to cut off the route of transmission in the infection chain,protect susceptible persons, and ultimately control or eliminate the source of infection.
Therefore, it is an important measure to prevent the spread of infectious diseases.
From a medical point of view, the goal of "isolation" is to prevent the spread of infection and ultimately eliminate or control the source of infection.
That is to prevent and limit the infectious factors of infected patients directly
or indirectly to susceptible persons,
or to those who may pass on such factors to others, and at the same time, enable infected patients to receive timely treatment under control and return to health as soon as possible.
Why choose container house?
In the construction field, it is called an assembled modular container house, also known as a container building or a container house.
It is a single room as a prefabricated unit.
The external wall panels and interior decoration of each unit are shipped to the factory after completion.
A building structure to be installed on site.
Compared with the traditional building structure, the container house has the following advantages:
(1) Convenient transportation, installation and movement, flexible combination;
(2) The cost is low and it can be completed quickly;
(3) The house can be recycled, and no construction waste is generated during use;
(4) The interior is completely renovated and can be used immediately.
Admittedly, it is precisely because of the advantages of rapid assembly and baggage check-in that the container house can be delivered to the Huoshenshan (Fire God Mountain) hospital within 10 days.

The development of Residential steel building Have a good material and technical foundation
How will Residential steel building develop in the future?
What should be considered before building Residential steel building?
What are the issues that need to be considered when constructing Residential steel building?
Due to the flexibility of Residential steel building design, in addition to high-rise buildings, low- and multi-storey residential buildings also have good adaptability for the residential system. At the same time, the development of villas in low- and multi-storey houses can use light steel structures such as cold-formed C-shaped steel or Small hot-rolled steel forms a keel structure system; high-rise buildings can use hot-rolled H-shaped, welded H-shaped, welded box-shaped, cold-formed thin-walled square steel pipe filled with concrete, round steel pipe filled with concrete, etc. to form a steel frame body and steel support frame system , Steel frame concrete shear wall system, etc.; while building villas and rural buildings, wall column systems can be used.
1. The cooperation between building equipment and Residential steel building is the first problem encountered by residents. Therefore, how to use advanced technology to develop various equipment suitable for steel structure residence is a problem we must solve.
2. The cost of Residential steel building is the most concerned issue of real estate developers. Steel structure residence should be located in medium and high-grade residence. Steel structure residence building is a systematic project. Management and coordination should be strengthened from the links of design, manufacturing, transportation, installation, maintenance and management, so as to reduce costs and improve comprehensive economic benefits.
1. Selection and development of exterior wall panels for Residential steel building is one of the key issues in the promotion of steel structure residential buildings. In addition to meeting the technical requirements of exterior wallboards, it is also necessary to make wallboard raw materials suitable for local conditions, work-oriented production, transportation, installation and connection.
2. The structure of Residential steel building should be safe and reasonable, the node structure should be convenient and reliable, and create conditions for component production, transportation and hoisting.
3. The seismic performance of Residential steel building has a lot to do with the regularity of structural layout. The structure layout is irregular, it is easy to be damaged during an earthquake, and in addition to the elastic design, the elasto-plastic layer displacement check calculation is also required. Therefore, we should try our best to make the structural layout meet the regularity requirements.
Overall, the important role of Residential steel building in our daily lives is perceived by more and more people. Qingdao Xinguangzheng Steel Structure Co., Ltd. strives to offer high quality Residential steel building at reasonable prices, efficient production times and the most professional customer service.
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.

Generally speaking, the installation procedures of industrial steel building include installation of steel columns, installation of inter-column supports, temporary installation of steel crane beams, roof beams, roof supports, steel crane beams, etc., correction, fixation, and structural installation of maintenance.
What is the specific process of industrial steel building construction?
How to regularly maintain industrial steel building?
How to consider the cost of industrial steel building construction?
1. Lifting the main structure of industrial steel buildings: connecting steel carriers on the ground, erecting steel columns, lifting steel carriers, connecting secondary structures, correcting the deviation of the main structure, installing crane carriers (optional), lifting intermediate layers (optional), and coating with fire resistant paint pack.
Main control quality: The deviation of the main structure should meet the specifications and design requirements and the initial and final application of high-strength screws should meet the requirements.
2. Installation of secondary structure: roofing posts, roof wall supports, flange supports, etc.
3. Laying of roof plate and insulation layer: first lay insulation layer, then assemble roof plate (in some projects a position of steel fabric is also placed under the insulation layer to prevent a fall of the insulation layer, this mainly depends on insulation layer level)
Main quality control: The roof is mainly waterproof, therefore the plate should be covered with the plate, the nail position, the glue coating should be full or not, the glue should be wiped clean and the coating on the surface of the plate should not be damaged to rust etc. to avoid.
industrial steel building wall maintenance and installation: mainly the installation of wall insulation and wall panels.
The main quality control of industrial steel building: the wall is mainly an aesthetic problem, and a window area is waterproof. There is also the problem of installation deviation. For example, the bottom should be flat, the entire plane should be flat, the flatness deviation between the board and the board should meet the requirements, and so on.
The detailed structure of the industrial steel building: mainly the installation of some trims, such as the wrap angle between the roof and the wall, the wrap angle at the corner of the wall, the flooding board between the wall panel and the brick wall, the door and window trim, etc.
The price of industrial steel building can only be compared with certain basic conditions, such as whether it is imported or domestic color panels, its thickness, coating; insulation material and thickness; whether there is a skylight; workshop bays and spans; whether there are cranes, crane tonnage, Many factors such as the level of the work system are related, and the impact of the price difference in other regions and the qualification level of the construction unit cannot be ignored.
The industrial steel building has achieved an irreplaceable position in industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. is committed to providing different kinds industrial steel buildings of high quality for all customers from all over the world.
Industrial steel building is easy to move and recycle without pollution. These are stronger than traditional workshops, and the walls of the steel structure workshops can also be filled with bricks, which are completely load-bearing. All future plant constructions will be steel structure plants. Here we are going to introduce the steps of installing Industrial steel building.
What are the raw materials used in industrial steel building?
What is the main installation process of industrial steel building?
What is the production and installation process of industrial steel building?
In addition to iron and carbon, the raw materials of industrial steel building also contain other elements. Divided into permanent elements; occasional elements; hidden elements and alloying elements. The common elements are manganese, silicon, sulfur, and phosphorus. Incidental elements are due to the different origins of ore (there are intergrowth ore mixed with iron) and scrap steel as raw materials, such as copper, titanium, vanadium, rare earth elements, etc., are brought into steel during smelting and process operations. The cryptic elements refer to non-metal elements with a small atomic radius, such as oxygen and hydrogen. Alloying elements refer to elements specially added to change the composition, such as chromium, nickel, tungsten, molybdenum, vanadium, etc.
Carbon steel (referred to as carbon steel) is an iron-carbon alloy with a carbon content of more than 0.0218% and less than 2.11%. Because carbon steel has good mechanical properties and process properties, and is large in output and low in price, it is a metal material that is widely used in mechanical engineering. However, carbon steel also has some shortcomings, such as low hardening energy, poor temper softening resistance, and low yield ratio. The strength potential of carbon steel cannot be fully utilized even after heat treatment. In order to meet the continuous development of modern industry and science and technology, alloy steel was developed.
Foundation → production and installation foundation is divided into (foundation ground survey → foundation excavation → embedded screws → foundation casting → later foundation grouting → outdoor water dispersion → outdoor drainage ditch (some factory design indoor drainage ditch or cable ditch suggestion Completed simultaneously with installation)→Enclosure masonry→tiling tiles, etc.)
The production and installation are divided into (processing production→component painting→structural pre-assembly→steel component hoisting→main structure adjustment→purlin installation→door and window column installation→gutter downpipe installation→steel component painting (some are fireproof, some are Anti-corrosion, according to design requirements) → roof panel (some with steel mesh, some with insulation layer, completed at the same time) → wall panel installation → door and window installation → water supply and drainage installation → electrical equipment installation)
