Steel structure and PEB

Aug 09, 2019

The steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column and steel truss made of steel and steel plates, and adopts rust-preventing and rust-preventing processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or components. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rises and other fields.

Steel structure and PEB(alles)

What are its characteristics? as follows:

1. High material strength and light weight

The steel has a high strength and a high modulus of elasticity. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the steel structure has a small cross section, light weight, easy transportation and installation, and is suitable for large span, high height, and heavy bearing capacity. Structure.

2, steel toughness, good plasticity, uniform material, high structural reliability

Suitable for impact and dynamic loads, with good seismic performance. The internal structure of the steel is uniform and close to the isotropic homogeneous body. The actual working performance of the steel structure is in line with the calculation theory. Therefore, the steel structure has high reliability.

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

Steel structural members are easy to manufacture at the factory and assembled on site. The mechanized manufacturing of steel structural members in the factory has high precision, high production efficiency, fast assembly speed and short construction period. Steel structure is the most industrialized structure.

4, steel structure sealing performance is good

Since the welded structure can be completely sealed, it can be made into a high-pressure container with good airtightness and water tightness, a large oil pool, a pressure pipe and the like.

5, steel structure is heat resistant and not fire resistant

When the temperature is below 150 ° C, the properties of the steel change little. Therefore, the steel structure is suitable for use in a hot workshop, but when the surface of the structure is subjected to heat radiation of about 150 ° C, it is protected by a heat shield. When the temperature is between 300 ° C and 400 ° C, the strength and elastic modulus of the steel are significantly reduced. When the temperature is around 600 ° C, the strength of the steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected with refractory materials to increase the fire rating.

6, steel structure is poor corrosion resistance

Especially in the environment of wet and corrosive media, it is easy to rust. General steel structures are to be rusted, galvanized or coated and regularly maintained. For the structure of the offshore platform in seawater, special measures such as “zinc block anode protection” are required to prevent corrosion.

7, low carbon, energy saving, green and environmentally friendly, reusable

The demolition of steel structures will produce almost no construction waste, and the steel can be recycled and reused.

PEB is Pre-engineered Building, prefabricated steel structure, which is a component of custom steel structure according to customer's structural and architectural requirements. All major and minor components are designed and processed at the factory: shearing, punching, drilling, welding, and finally transported to the construction site. At the construction site, the components are bolted to the nodes after assembly; this reduces cost and assembly time.

Then what are its characteristics? as follows:

1. Significantly reduce costs

Precast steel structures can reduce costs from 20% to 30% compared to traditional buildings. Minimize the weight of the part subjected to less load to reduce the amount of steel.

2. Durability

Prefabricated steel structures are durable and resistant to heavy rain, strong winds, and large earthquakes.

3. Quick installation

Prefabricated steel structures can be installed quickly because each project has assembly details, components that have been machined and detailed installation instructions.

4. Flexibility

Prefabricated steel structures can have a small or no column inside to facilitate the storage of large quantities of equipment, installation of cranes and internal activities.

In addition, prefabricated steel structures are flexible, easy to expand, and economical and transportation costs are low.

5. Energy saving

Currently, prefabricated steel construction is a green solution that can reduce CO2, energy savings, and more.

Prefabricated steel construction can effectively save heat and cooling energy. In particular, all components do not generate dust, noise and can effectively reduce installation time.

There is a close relationship between the steel structure and the PEB, and the customer determines the formation of the steel structure based on the prefabricated steel structure. Prefabricated steel construction can be from simple storage structures to any complex steel structure frame office building. The cost of prefabricated steel construction is lower than most other types of buildings.
