steel structure building

The steel structure building opens up industry boundaries between the real estate, construction, and metallurgical industries, and integrates them into a new system. This is the steel structure building system that is generally optimistic about the industry.

Steel structure buildings are stronger and more earthquake-proof than traditional concrete buildings since they use steel plates or steel profiles instead of reinforced concrete. And because the components can be manufactured in factories and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and be greener and environmentally friendly, so it is widely used in industrial and civil buildings all over the world.

The application of steel structure buildings in high-rise and super high-rise buildings is becoming more and more mature, and it has gradually become the mainstream construction technology, which is the development direction of future buildings.

Introduction

A steel structure building is a building in which building steel constitutes a load-bearing structure. The load-bearing structure is usually composed of beams, columns, trusses, and other components made of section steel and steel plates. Together with the envelope structures such as roof, floor, and wall, they form a fully planted building.

Construction steel usually refers to hot-rolled angle steel, channel steel, I-beam, H-beam, and steel pipe. A building whose components constitute a load-bearing structure is called a steel structure building. In addition, thin-walled sections such as L-shaped, U-shaped, Z-shaped, and tube-shaped steels that are cold-rolled from thin steel sheets, rolled or unrolled, and the load-bearing components formed by them and small steel materials such as angle steel and steel bars Structural building, generally called light steel structure building. There are also suspension structure buildings using steel cables, which are also steel structure buildings.

The strength and elastic modulus of steel is high, the material is uniform, and the steel structure has good plasticity and toughness, high precision, convenient installation, high degree of industrialization, and fast construction, but it has poor corrosion resistance and fire resistance and requires frequent maintenance.

Advantages and disadvantages

advantage

1. The construction time is greatly saved, and the construction is not affected by the season

2. Increase the usable area of residential space and reduce construction waste and environmental pollution

3. Building materials can be reused, driving the development of other new building materials industries

4. Good seismic performance, easy to transform in use, flexible and convenient, bringing comfort to people, etc.

5. High strength, lightweight, high safety, and wealth of components, reducing building cost

6. In line with the national sustainable development strategy, low-carbon, green, environmental protection, energy-saving, etc. are the industries supported by the state

shortcoming

Due to the non-renewable land resources, the Ministry of Construction has ordered the prohibition of the use of traditional clay bricks. At the same time, my country’s steel production has reached 1 billion tons. The serious oversupply situation has forced iron and steel enterprises to take a different approach and introduce the mature steel structure residential building system from abroad. At the same time, a new way has been found for the construction industry and the steel industry. Therefore, steel mills and building materials companies are at the forefront of steel structure housing.

1. It is not heat-resistant and fire-resistant, and needs to be coated with fire-resistant paint on the surface

2. It is susceptible to corrosion, and the surface needs to be coated with anti-corrosion paint to reduce or avoid corrosion and improve the durability
