Steel Structure Building

With the development and popularization of Industrial Steel Buildings, different types of steel structure buildings gradually appear in our lives. Steel structure manufacturerssummarize the stress characteristics of different structures of steel structure buildings.

According to the structural stress characteristics of prefab steel structure buildings, it can be divided into portal rigid frame structure, space truss structure, string beam structure, string support dome structure, grid structure and multi-story structure. Today, I will mainly introduce three common structures: portal rigid frame structure, space truss structure, and string beam structure.

1. Portal frame structure. This kind of steel building components is light and small in height, and is a common structural form in steel structure buildings. Since the site is all bolted, the engineering installation is relatively simple.

2. Space truss structure. This type of steel structure building has heavy components and large spans, mainly composed of steel pipes, with strong cross-section bearing capacity and can be bent into curved shapes. On-site hoisting and welding work is heavy.

What is steel structure building?

A steel structure building is a building in which building with General steel, it is 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, which are cold-rolled and formed from thin steel sheets, rolled or unrolled, as well as the load-bearing components formed by them and small steel materials such as angle steel and steel bar, etc. Structural building, generally called light steel structure building. There are also suspension structure buildings using steel cables, which are also steel structure buildings.

What are the pros and cons of the steel structure building?

Pros

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

Cons

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

Questionnaire

Below issues are needed to make a solution.

3.1 Location (where will be built? ) _____country, area

3.2 Size: Length*width*height _____mm*_____mm*_____mm

3.3 wind load (max. Wind speed) _____kn/m2, _____km/h, _____m/s

3.4 snow load (max. Snow height)

_____kn/m2, _____mm

3.5 anti-earthquake _____level

3.6 brick wall needed or not If yes, 1.2m high or 1.5m high

3.7 thermal insulation If yes, EPS, fiberglass wool, Rockwool, PU sandwich panels will be suggested; If not, the metal steel sheets will be ok. The cost of the latter will be much lower than that of the former.

3.8 door quantity & size _____units, _____(width)mm*_____(height)mm
