Do you know the seven characteristics of steel frame structure?

Seven characteristics of steel frame structure in building engineering:

I. Characteristics of steel frame structure materials

The traditional construction industry mainly uses civil engineering, using soil as raw material to make bricks and tiles, calcining limestone to produce lime, using sand and cement to make concrete, and using steel bars and concrete to make reinforced concrete members. The material of steel structure, unlike the traditional construction industry which uses a lot of local materials, is all kinds of steel, aluminum and alloys provided by modern metallurgical industry, all of which are products of modern industry. There are also all kinds of fluxes and various coating materials, plastics and adhesives produced by modern chemical industry. Steel structure materials have accurate standards, high inspection requirements, strict storage, transportation and processing conditions, and most of them need mechanized operation.

Second, the steel structure production and installation characteristics

It is basically manufactured in the factory, transported to the site and installed, and the main structure is completed by welding or bolting. Because it is manufactured in the factory, various processing methods of modern manufacturing industry can be used, including welding, bolting, cast steel, hot bending and cold rolling, and various detection methods can be used, including physical and chemical tests, ultrasonic flaw detection, radiographic flaw detection, magnetic particle flaw detection, etc., so that the processed components are more accurate and the quality is more guaranteed.

Third, the steel structure requires high measurement.

Generally, the civil dimension error is measured in centimeters, while the steel structure is measured in millimeters. If it fails to meet the requirements, it will be impossible to install it smoothly, and forced installation will also produce huge initial stress, which will bring hidden dangers to the structure.


Four, steel structure involves material science.

Various processing technologies, various detection technologies, various assembly technologies, and welding technologies such as laser welding, high-frequency welding, electroslag welding, and gas shielded welding are all related to modern science. Steel structure is a precise structure. Modern buildings are not only simple three-dimensional, but also consider the connection in multiple directions, which requires CNC machine tools and computer networking operation. Therefore, employees have high quality requirements, and they must master certain professional technical knowledge and have certain operating skills.

Five, steel structure enterprises should have a design team.

From the construction drawing to the detailed drawing that can be read by workshop workers, the design needs to be deepened, and designers are indispensable. In general, the construction enterprises mainly turn over the samples of steel bars, and the higher-level master of steel bar workers can undertake this work, so there are basically no full-time designers. Steel structure enterprises need full-time designers, and steel structure enterprises also need a testing team to conduct physical and chemical reinspection on raw materials to ensure that the quality of raw materials meets the specifications and design requirements, and to carry out flaw detection on welds to ensure that the quality of welds can meet the specifications and design requirements. Therefore, they have to set up their own physical and chemical laboratories, otherwise they have to commission relevant testing work.

Six, the steel frame structure has remarkable seismic effect.

The anti-vibration effect of steel frame structure is also the most significant, and the safety factor of steel frame structure will be higher in the process of bearing gravity and power.

Seven, the steel structure has a wide range of applications.

The steel frame structure is also more comprehensive in use, which is inseparable from the high density of the steel frame structure from the building and manufacturing of the factory building to the construction of the site, and the steel frame structure is a recycled material, which is easier to complete in transportation; However, attention should be paid to the characteristics of the steel frame structure itself, and the corrosion resistance of steel will be low, and rust will occur for a long time. It is recommended to maintain the steel frame structure regularly.
