Prefabricated steel structure warehouse with sandwich wall panel

Grid structure is a material commonly used in many buildings, mainly in sandwich wall panel prefabricated steel structure warehouses. At the same time, in the sandwich wall panel prefabricated steel structure warehouse project, the sandwich wall panel prefabricated steel structure warehouse technology mainly uses steel production, composed of steel beams, columns, steel trusses and other components made of steel and steel plates; The structure connected by welds, bolts, or rivets between various components or parts is one of the main types of building structures. Below is a specific understanding of the advantages and disadvantages of sandwich wall panel prefabricated steel structure warehouses

Characteristics of prefabricated steel structure warehouse with sandwich wall panels

Steel based structures are one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings; The material has good homogeneity and isotropy, and belongs to the ideal elastic body, which is more in line with the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization. The prefabricated steel structure warehouse with sandwich wall panels should study high-strength steel to greatly improve its yield point strength; In addition, new types of steel profiles, such as H-beams (also known as wide flange steel), T-beams, and profiled steel plates, need to be rolled to meet the needs of large-span structures and super high-rise buildings.

The sandwich wall panel prefabricated steel structure warehouse also has a lightweight sandwich wall panel prefabricated steel structure warehouse system without thermal bridges. The building itself is not energy-saving. This technology uses clever special connectors to solve the problem of cold and hot bridges in the building; The small truss structure allows cables and water supply and drainage pipes to pass through the wall, making construction and decoration convenient for grid processing.

Advantages and disadvantages of prefabricated steel structure warehouses with sandwich wall panels

1. High material strength and light weight

Steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the component section of the prefabricated steel structure warehouse with sandwich wall panels is small, the self weight is light, and it is easy to transport and install. It is suitable for the processing of structural grids with large spans, high heights, and load-bearing capacity.

2. Steel has toughness, good plasticity, uniform material, and high structural reliability

Suitable for withstanding impact and dynamic loads, with good seismic performance. The internal structure of the steel is uniform, almost isotropic and homogeneous. The actual working performance of the prefabricated steel structure warehouse with sandwich wall panels is in line with computational theory. So the prefabricated steel structure warehouse with sandwich wall panels has high reliability.

3. The prefabricated steel structure warehouse with sandwich wall panels has a high degree of mechanization in manufacturing and installation

The prefabricated steel structure warehouse components of sandwich wall panels are easy to manufacture in the factory and assemble on the construction site. The factory mechanization manufacturing of sandwich wall panels prefabricated steel structure warehouse components has high precision, high production efficiency, fast on-site assembly speed, and short construction period. Sandwich wall panel prefabricated steel structure warehouse is a highly industrialized structural grid processing.

4. Sandwich wall panel prefabricated steel structure warehouse has good sealing performance

Due to the welding structure, it can achieve complete sealing and can be used as high-pressure vessels, large oil tanks, pressure pipelines, etc. with good airtightness and water tightness.

5. Sandwich wall panel prefabricated steel structure warehouse, heat-resistant but not fire-resistant

When the temperature is below 150 ℃, there is little change in the properties of the steel. Therefore, sandwich wall panel prefabricated steel structure warehouses are suitable for hot workshops, but when the surface of the structure is exposed to thermal radiation of around 150 ℃, insulation panels should be used to protect it. When the temperature is between 300 ℃ -400 ℃, the strength and elastic modulus of the steel both significantly decrease. When the temperature is around 600 ℃, the strength of the steel tends to zero. In buildings with special fire requirements, the prefabricated steel structure warehouse with sandwich wall panels must be protected with refractory materials to improve the fire resistance level of the grid frame processing.

6. Poor corrosion resistance of prefabricated steel structure warehouse with sandwich wall panels

Especially in environments with high humidity and corrosive media, it is prone to rusting. Generally, prefabricated steel structure warehouses with sandwich wall panels need to be rust removed, coated with zinc or paint, and regularly maintained. For offshore platform structures located in seawater, measures such as zinc block anode protection are adopted to prevent corrosion.
