China Supplier Drywall Mounted Panel Frame Drywall Metal Studs and Tracks Stud Frames for Steel Structure Building

Steel structure is composed of steel material structure, is one of the main types of building structure. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. It adopts silanization, pure manganese phosphating, washing and drying, galvanized and other rust removal and rust prevention processes. Welds, bolts, or rivets are usually used to join components or parts. Because of its light weight and simple structure, it is widely used in large workshops, venues, super high-rise buildings and other fields.

Steel is characterized by high strength, light weight, good overall rigidity and strong resistance to deformation. Therefore, it is especially suitable for the construction of large-span, super-high and super-heavy buildings; The material is an ideal elastic material with good homogeneity and isotropy, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, and can withstand dynamic load well; The construction period is short; High degree of industrialization, can be specialized production, high degree of mechanization.

 
Specification:

 
Features:
1. The material has high strength and light weight
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, its density and yield strength ratio is relatively low, so under the same stress conditions, steel structure has the characteristics of small section, light weight, easy to transport and installation, suitable for large span, high height, large load structure.
2. The steel has good toughness, good plasticity, uniform material and high structural reliability
Suitable for bearing impact and dynamic load, with good seismic performance. The internal structure of steel is uniform and close to the isotropic homoplast. The actual performance of steel structure is more consistent with the calculation theory. Therefore, the reliability of steel structure is high.
3. High degree of mechanization of steel structure manufacturing and installation
Steel structural members are easy to manufacture in factory and assemble on site. The steel structure member factory has the advantages of high precision, high production efficiency, fast assembly speed and short construction period. Steel structure is the most industrialized structure.
4. Good sealing performance of steel structure
Because the welded structure can be completely sealed, it can be made into high pressure vessels with good air tightness and water tightness, large oil pools, pressure pipelines, etc.
5. Steel structure heat resistant, not fire resistant
When the temperature is below 150℃, the properties of steel change little. Therefore, steel structure is suitable for high temperature workshops, but when the surface of the structure is exposed to thermal radiation of about 150℃, heat insulation plate should be used for protection. When the temperature is between 300℃ and 400℃, the strength and elastic modulus of steel decrease obviously. When the temperature is about 600℃, the strength of steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected by refractory materials to improve the fire resistance grade.
6. Poor corrosion resistance of steel structure
Especially in the environment of wet and corrosive media, it is easy to rust. General steel structures need to be derusted, galvanized or painted, and require regular maintenance. For offshore platform structures in seawater, special measures such as "zinc block anode protection" should be taken to prevent corrosion.
7. Low carbon, energy saving, green environmental protection, reusable
Demolition of steel structures produces little construction waste, and steel can be recycled.
 

Application program:
Compared with ordinary reinforced concrete structure, steel structure has the advantages of good homogeneity, high strength, fast construction speed, good seismic performance and high recovery rate. The strength and elastic modulus of steel are many times higher than that of masonry and concrete. Under the same conditions, the weight of the steel member is lighter. From the point of view of damage, steel structure has a large precursor of deformation in advance, belongs to ductile failure structure, can be found in advance, avoid danger.
Steel structure workshop has the advantages of light weight, saving foundation, less material, low cost, short construction period, large span, safe and reliable, beautiful appearance, stable structure and so on. Steel structure plant is widely used in long-span industrial plant, warehouse, cold storage, high-rise building, office building, multi-storey parking lot, residential building and other construction industries.

Steel structure installation:
Precast of steel components:
The prefabrication and assembly of steel components are carried out on steel platforms according to the installation sequence and technological requirements, and the welding quality must be guaranteed.
The distance between the joint of splicing flange plate and the joint of section steel web should be greater than 200mm. The splicing length of the flange plate shall not be less than 2 times the width of the plate; The stitching width and length of web should not be less than 300mm and 600mm respectively.
In order to facilitate welding and ensure welding quality, butt welding should be carried out on the steel platform on the ground as far as possible according to the size of the construction drawing, and butt welding should be carried out on the stiffening plate, connecting plate, backing plate and beam (beam) on the column and beam as far as possible.
In addition to fabrication and assembly of precast steel members on steel platforms in accordance with construction drawings and specifications, manufacturability of field installation and variation in installation dimensions should also be considered.
