Steel structure is one of the most important types of building structure. This structure is basically made of steel, steel columns, steel columns, and other parts of steel plate and steel plate, and is subjected to silverization, purification of manganese, cleaning process such as cleaning and growth prevention. Generally, diseases, storms, rivers are used to connect parts and parts. Since it is a simple building, it is widely applied to areas such as large workplaces, places and very high altitude.
 
This steel has the characteristics of high strength, light weight, good overall stiffness, and strong resistance to deformation. Therefore, it is particularly suitable for building large, elevated, and overweight buildings. This material has good uniformity and isotropy, making it an ideal elastic material that best conforms to the basic mechanical assumptions applied to general mechanics. This material has better plasticity and toughness, generates large deformation, and can withstand good dynamic loads. The construction cycle is short, the degree of industrialization is high, professional production is possible and high degree of mechanization.

 

Features:
1. High strength, light weight
Steel is very sturdy and flexible, with relatively low density and yield strength compared to concrete and wood. Therefore, under the same stress conditions, steel structures have the characteristics of small cross-section, light weight, and convenient transportation and installation. Suitable for large structures, skyscrapers, and heavy buildings.
2. Steel has good toughness, plasticity, material flatness, and high structural reliability.
Capable of withstanding impact and dynamic loads, and has excellent seismic performance. The internal structure of steel is uniform, close to the uniformity of isotopes. The actual performance of steel structure is more consistent with Theory of computation, so the reliability of steel structure is higher.
3. Advanced machinery for steel structure manufacturing and installation
Steel structures are easy to manufacture and assemble in the factory. Steel structure manufacturing plants have high processing accuracy, high production efficiency, fast assembly speed, and long construction cycles. Short rail steel structure is the highest structure in industry.
4. Steel structure with good sealing performance.
The welded structure can be completely sealed and can produce high-pressure vessels, large oil tanks, pressure pipelines, etc. Density of air and water density are good.
5. Steel structure is heat-resistant and non fireproof
At temperatures below 150 ° C, the performance of the steel remains almost unchanged. Therefore, steel structures are suitable for high-temperature workshops, but when the surface of the structure is exposed to thermal radiation of about 150 ° C, insulation plates should be used for protection. When the temperature is between 300 ° C and 400 ° C, the strength and elastic modulus of the steel significantly decrease. At a temperature of around 600 ℃, the strength of steel tends to zero. In buildings with special fire protection requirements, steel structures should be protected with refractory materials to improve their fire resistance level.
6. The corrosion resistance of steel structures is poor.
Especially in humid and corrosive environments, it is easy to rust. Generally, steel structures require pickling, galvanizing or painting, and require regular maintenance. Special measures should be taken for offshore platform structures in seawater, such as"protecting zinc block anodes"to prevent corrosion.
7. low carbon, energy saving, environmentally friendly and reusable
The demolition of steel structure buildings will hardly produce construction waste, and the steel structure can be recycled.
 

Application:
Compared with ordinary reinforced concrete structures, steel structures have the advantages of strong uniformity, fast construction speed, good seismic resistance and high recovery speed. Steel strength and elasticity are several times more than masonry and concrete, and under the same conditions the weight of steel components is low. As for damage, steel structures have significant preconditions for early deformation Belongs to ductile fault structures, it can be detected in advance to avoid danger.
The steel construction workshop has the advantages of low weight, which generally saves foundation, fewer materials, low cost, short construction time and large winch span. Safe and reliable, with beautiful appearance and stable structure. Steel structure workshops are widely used in large industrial factories, warehouses, cold stores, high rise buildings, office buildings and several parking spaces. Floors and other residential and construction industries.

Steel structure installation:
Precast of steel components:
Steel prefabrication and assembly are carried out on the steel platform according to the installation sequence, and the welding quality must be ensured according to the process requirements.
The connection distance of the profile steel flange should be greater than 200mm. The length of the wing attachment should not be less than twice the width of the plate. The connection width of the movement core should be less than 300mm and the length should be less than 600mm.
To easily facilitate and ensure the quality of welding, the collaboration should be performed according to the size of the construction designs, as much as possible on the ground steel line and as much as possible on the founders, connecting signs, gaskets and beams.
In addition to producing and collecting steel parts, attention should also be paid to change installation dimensions of steel plates based on the reality of installation on the site and architecture and specifications.
