What should I pay attention to when using Industrial steel building?

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.

What are the reasons why Industrial steel building is used more and more widely?

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.

What are the steps involved in the general process of Industrial steel building installation?

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.

• Why pay attention to the design of residential steel building?

What is the layout of the 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.

What issues should be paid attention to when designing residential steel building?

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.

Why pay attention to the design of residential steel building?

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 raw materials used in 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.

What is the main installation process of industrial steel building?

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.)

What is the production and installation process of industrial steel building?

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)

What are the advantages of using Steel building accessories to build houses?

1. The total weight of the building using Steel building accessories is light, which is about half of the concrete structure. At the same time, it can greatly reduce the foundation cost of the house.

2。 The construction speed of Steel building accessories is fast, and the construction period is at least one third shorter than that of the traditional residential system. A 1000 square meter building can be completed in only 20 days and five workers.

3. The house with Steel building accessories has good environmental protection effect. This is because the consumption of sand, stone and ash is greatly reduced during the construction of the residential buildings built by Steel building accessories. The materials used are mainly green, 100% recycled or degraded materials. When the buildings are demolished, most of the materials can be reused or degraded without causing garbage.

4. Steel building accessories is welcomed by everyone for its flexibility and abundance. Large bay design, indoor space can be divided by multiple schemes, which can meet the different needs of users.

5. The use of Steel building accessories meets the requirements of housing industrialization and sustainable development. The steel structure is suitable for mass production in the factory with a high degree of industrialization. It can integrate advanced finished products such as energy saving, waterproof, heat insulation, doors and windows, and apply them in a complete set, integrating design, production and construction, so as to improve the level of construction industry.

What are the common Steel building accessories on the market?

1. u-shaped bracket

The u-shaped bracket is also one of the important accessories of Steel building accessories. The bracket is used for the connection between the ground and the main material. In addition to the fixing function, the u-shaped bracket can also balance the overall bearing force.

2. Fishing rod bracket

The fishing rod bracket of the steel structure frame is a single-unit fixing device accessory, which is used for the initial fixing of the single-unit room.

Why do Steel building accessories need to be fireproofed?

The temperature resistance of steel is poor, and many of its properties change with the rise and fall of temperature. When the temperature reaches between 430-540℃, the yield point, tensile strength and elastic modulus of the steel will drop sharply, and the load-bearing capacity will be lost. Steel building accessories must be maintained with refractory materials.

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.

What are the welding sequence and process parameters of commercial steel building typical nodes?

(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℃

What points should be paid attention to when installing commercial steel building?

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.
