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)

How to remove the rust spots on the surface of Steel building accessories?
For Steel building accessories that have been used for a period of time, there are inevitably some attachments on the surface, such as rust, dirt, dust, old paint film, etc. Before painting the surface of Steel building accessories, if these attachments are not completely removed, although they can be temporarily covered after painting, they play a role of isolation, which makes the coating and the component substrate bond If the strength is severely reduced, the paint film will fall off prematurely, which will eventually reduce the corrosion resistance of the surface coating and fail to play the protective role of the coating. Therefore, before painting the surface of the component, the attachments on the surface of Steel building accessories should be thoroughly cleaned.
In order to improve the quality of rust removal and work efficiency. To improve the working conditions of construction workers, the current Steel building accessories derusting work has adopted a large number of wind-driven or electric small equipment. The main rust removal methods using equipment are:
(1) Angle grinder: This small pneumatic equipment is mainly used to clean flat areas. It can use sandpaper, grinding wheels and wire brushes as needed.
(2) Needle Bundle Derusting Machine: This kind of small pneumatic equipment is generally equipped with 30-40 needle bundles, which can be adjusted with different working surfaces, which are mainly suitable for curved, narrow, uneven and cracked places.
(3) Single-head cold air gun: This small pneumatic equipment is also called zinc knocking. It uses the impact of the knocking head to remove rust. The diameter of the shovel head is generally 25-40mm, and it can impact 1000 to 6000 times per minute. Suitable for relatively narrow places.
1. Two-hole connection accessories
One of the main accessories of Steel building accessories is the double-hole connection accessory, which is mainly used to connect with the corners. The corners on both sides of the right-angle connection can reduce the pressure on the alloy. At the same time, the recesses of the building materials can be based on the aluminum alloy frame.
2. Single hole connector
Steel building accessories also has an important accessory, the single-hole connector, which has a completely different function from the double-pipe connector. It is mainly used for the affinity connection between the aluminum alloy frame and the ground in the ground installation. Therefore, the single-hole connector has The role of anchor bolts.
The Steel building accessories have been widely used in daily life and industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Steel building accessories for their customers.
Generally speaking, Steel building accessories include: steel column systems, steel beam systems, support systems, connection systems, purlin systems, and brace stairs. This is a part and an indispensable part of every steel structure project.

The length of the straight overpass on the east side is 56.3 meters and the width is 5 meters. The length of the straight overpass on the west side is 49 meters and the width is 5 meters. The diameter of the main bridge surface of the central circular overpass is 56 meters. The narrowest part is 6.5 meters and the maximum width is 12 meters. The construction of the overpass on Hongqi Road can avoid the interference of people and vehicles To improve the road capacity, and effectively solve the problem of efficiency and safety of a large number of people crossing the street.
After completion, it will become the most characteristic commercial block with urban flavor in the main urban area of Pingdu City, as well as the landscape landmark and cultural landmark of Pingdu.
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.
2. Fast.
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.
4.Economical.
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 has a wide range of applications and can be used in factories, warehouses, office buildings, stadiums, hangars, etc. to be used. It is suitable not only for single-storey large-space buildings, but also for the construction of multi-storey or high-rise buildings.
What are the architectural features of industrial steel building?
What is the reason why more and more people are choosing industrial steel building?
What types of construction are available for industrial steel buildings?
Insulation: Avoid heat transfer on both sides of the metal roof to ensure that the ambient air temperature is stable. The thermal protection function is realized by filling thermal protection materials (usually used glass wool and stone wool) under the metal roof plate. The heat conservation effect is expressed by the U-value and the unit is W/M2K. The thermal insulation performance is determined by the following factors: raw material, density and thickness of the thermal insulation cotton; the humidity of the thermal insulation wall, the method of connecting the metal roof plate and the underlying structure (to prevent the phenomenon of the "cold bridge"), the repeated ability of the metal coating to heat radiation.
Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain positions on the metal roof, the duration of the daylight should be adjusted to the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
Beautiful: The metal roof of the industrial steel building has a good texture and a pleasant color.
Check the heat expansion and contraction: check the contraction shift and direction of the metal roof plate. Make sure that in areas with high temperature differences the metal roof plate is not damaged by heat expansion and contraction.
Anti-avalanche: install snow barriers on the metal roof in snow-covered areas to prevent a sudden fall of snow.
Anti-ice caps: industrial steel building can prevent rain and snow from forming ice caps on the mould.
The frame of the industrial steel building is the main structure of the system frame. It is a flat structure consisting of columns and frames. All horizontal water loads and most vertical loads are transferred to the foundation via the plant frame. In industrial buildings, the industrial steel building frame has the following three most common types of construction;
1. The single-storey steel structure factory building frame is a single-storey frame formed from the stacked column of the factory building and the frames anchored to the top of the column (the column top can be called the system bent when the column top is foldable).
2. A rigid one-storey frame, a one-storey frame formed by a rigid connection of columns with an equal or gradual cross-section and frames on the top of the column.
3. Multi-layered frame, a multi-layered frame formed by joining columns and floor supports (or specialist works) and roof supports or roof supports.
Having learned so much about industrial steel building, it is also a difficult problem to select from many manufacturers the one with high quality and low price. Qingdao Xinguangzheng Steel Structure Co., Ltd. has been a Chinese pioneer in industrial steel building for several years. You can work with customers from design to completion to ensure that all technical requirements are met.
