Descriptiom

A multi-storey steel building is a three-dimensional or light steel building with a number of storeys containing vertical circulation via elevators and stairs. Based on preliminary analysis and validation, a wide range of methods have been adopted for these buildings of different heights. Multi-storey steel buildings are generally designed to be used as hospitals, commercial malls or apartments.

As the ideal solution for commercial buildings, multi-storey buildings can be built faster than other traditional buildings due to the use of a high level of material prefabrication, design precision, optimal quality checks and risk-free construction.

Parameter

Advantages of multi-storey steel structures

I. Material grade

1. Carbon structural steel: Q235B, which is a common construction steel, with good weldability and plasticity.

2. High-strength structural steel: Q345B, the strength of this steel is higher than Q235B, suitable for bearing large loads of structures.

3. Special purpose steel, this type of steel has special physical or chemical properties for specific engineering needs.

ⅱ. Quality standards

1. Certificate: ISO9001:2008, which is an international quality management system certification.

2. Steel structure design specification: GB 50017-2003, which is the Chinese national standard, stipulates the design requirements of steel structure.

3. Cold-formed thin-wall steel structure technical specification: GB50018-2002, this specification specifies the design and construction requirements of cold-formed thin-wall steel structure.

4. Building structure design load code. GB 50009-2006, this specification specifies the load design requirements for building structures.

5. Steel construction quality acceptance: GB50205-2001, this specification specifies the quality acceptance requirements for steel construction.

6. "High-strength Steel structure Design, construction and acceptance Code" JGJ82-2011, which is China's industry standard, stipulates the design, construction and acceptance requirements of high-strength steel structures.

7. Steel structure building welding technical specifications: JGJ 81-2002, this specification specifies the technical requirements for steel structure building welding.

8. Technical specification for steel structures in high-rise buildings: (JGJ99-98), this specification specifies the design and construction requirements for steel structures in high-rise buildings.

Iii. Structural assembly

1. Steel frame: composed of h column, h beam and C/ Z-purlin, the connection method of steel structure has two kinds of welding and bolt connection.

2. Surface treatment: including spray paint and galvanized two, can protect the steel from corrosion.

3. Roof and walls: Usually use color steel tile or color steel sandwich board, these materials are both beautiful and durable.
