Station of Steel Structure

Introduce

Metallic shape platform is a structural platform composed of metal cloth, that's one of the number one forms of building structure of the platform.the form is especially composed of steel beam, metallic column, metallic truss and one-of-a-kind additives made from type steel and metal plate, and adopts silanization, natural manganese phosphorization, washing and drying, galvanizing and one-of-a-kind rust removal and rust prevention era.welds, bolts or rivets are typically used among the people or additives.due to its mild weight and easy creation, it's miles widely used in platform engineering projects.

characteristic

1. High material strength and light own weight

High steel strength and high elastic modulus.Compared with concrete and wood, the ratio of density to yield strength is relatively low, so the components of steel structure has small section and light weight, easy transportation and installation.

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

Suitable for bearing the impact and power load, with good seismic performance.The internal tissue structure of the steel is uniform, close to the isotropic homogeneity.The actual working performance of the steel structure is more in line with the calculation theory.So the steel structure reliability is high.

3. High degree of mechanization of steel structure manufacturing and installation

Steel structure components are easy to manufacture in the factory and assemble on the construction site.Factory mechanized manufacturing of steel structure components finished products with high precision, high production efficiency, fast site assembly speed, short construction period.Steel structure is the most highly industrialized structure.

4. Good sealing performance of the steel structure

Because the welding structure can be completely sealed, can be made into gas tightness, water tightness are very good high pressure vessel, large oil tank, pressure pipeline, etc.

5. Steel structure is heat resistant and not fire resistant

The steel properties vary very little when the temperature is below 150℃.Therefore, steel structure is suitable for thermal workshop, but the surface of the structure is about 150℃ of thermal radiation, heat insulation plate should be used to protect.At 300℃ -400℃.Steel strength and elastic modulus have decreased significantly, the temperature at about 600℃, the strength of steel tends to zero.

Low-carbon, energy-saving, green and environmental protection, reusable

The demolition of steel structures can hardly produce construction waste, and the steel can be recycled.

Installation difficulties and key control points of steel structure engineering

In the steel structure engineering, the control of ground foot bolt installation and component production and processing quality is the key control point.The key control point of installation is the control of installation sequence and installation accuracy.

Steel member Ann

Hoist according to the hoisting machinery situation in the project area.Generally, the car crane model is selected according to the heaviest steel components to ensure that the safety factor is large enough, and the lifting safety check is required when necessary.Before lifting, the safety of the car crane itself should be checked.

Steel column correction

After the steel column is installed in place, the verpendiculality and elevation of the steel column are retest successively.When the first steel column is in place, the elevation of the bottom of the column should also be adjusted. See the schematic diagram of the steel column correction for details, and all the anchor bolts and leveling bolts should be fastened in place.Installation accuracy of steel columns shall comply with EN 1090-2:2008.
