China Steel Structure Association held a scientific and technological achievement evaluation meeting on "spatial grid structure integral hoisting technology and key equipment research and development and application"

On April 16, 2023, the China Steel Structure Association organized a video conference on the evaluation of scientific and technological achievements of "spatial grid structure integral hoisting technology and key equipment research and development and application. The achievement was jointly completed by the Seventh Engineering Co., Ltd. of the First Public Administration of China Communications, Chang'an University, Zhengzhou University and other units.

New Technology of Erection of Green Building with Steel Structure Reflects Energy Saving and Environmental Protection

With the increasing pressure of energy conservation and emission reduction in China, the state pays more and more attention to environmental protection and natural resource protection. The development of green buildings has been written into the national "Twelfth Five-Year Plan", which is undoubtedly a rare development for the steel structure industry. opportunity. The "Twelfth Five-Year Development Plan for the Construction Industry" officially announced by the Ministry of Housing and Urban-Rural Development pointed out that during the "Twelfth Five-Year Plan" period, the total output value and added value of the national construction industry should grow at an average annual rate of more than 15%.

The fire protection of steel structure buildings should meet the fire protection requirements.

Any building in the design, must do a good job of fire protection and other important protection measures. With the rapid development of economy, China's construction steel structure has been more and more widely promoted and applied since the 1990 s. Modern steel structure engineering is an important part of large-scale modern buildings in China. Because the steel structure has its light weight, low foundation cost, suitable for soft foundation and easy installation, fast construction, short cycle, construction pollution is small, good earthquake resistance and other comprehensive advantages, so the steel structure building was listed as a promotion project by the original Ministry of Construction.

Steel structure residence is a high and realistic choice

According to the interim report of steel enterprises issued by the China Federation of Iron and Steel Enterprises, listed iron and steel enterprises suffered large-scale losses in the first half of the year, and their net profits narrowed sharply, and the degree of losses further intensified in late August. Some people believe that steel overcapacity and excessive inventory affect the profits of the steel industry in the later stage, while others believe that the deep-seated reason lies in the slowdown of China's economy and the sluggish market demand.

Steel structure engineering regardless of the nature of the country

It has been widely used in developed countries, so it is called the main representative of green building. The foundation cost is low, the construction area is large, the construction quality is high, it is suitable for industrialization and standardized production, can be dry green construction, suitable for different climatic conditions, is not affected by the construction season, and has the advantages of low comprehensive cost. At the same time, the steel structure It can also reduce the pollution of construction waste to the environment and can be recycled in the whole life cycle. Steel structure building is in line with the development direction of energy conservation and circular economy in China, and it is one of the structures with the least impact on the urban environment.

Relevant theory of steel structure reinforcement

If the steel structure has serious defects and damages or changes the operating conditions, and the strength, rigidity or stability of the structure does not meet the operating requirements after inspection, the steel structure shall be strengthened. Due to the design or construction of steel structure defects, such as insufficient weld length, rod cut is too long, so that the section weakened too much and so on.

Formation and Prevention of Stress Corrosion Cracks in Steel Structures

With the progress of science and technology, as well as the deepening of people's understanding of steel structure, steel structure this new form of building structure is more and more used. Due to the different technical level and processing technology of the production or installation manufacturers, the quality of the steel structure is also very different. Xuzhou Sifang will introduce the formation and preventive measures of stress corrosion cracks in the steel structure.

How long can the "Chinese steel structure" go?

The Group believes that in the information age of economic globalization, informatization will become the only way for SMEs to enhance their competitiveness, and e-commerce will become the key path for enterprises to achieve informatization. Therefore, the Group will continue to focus on promoting the e-commerce and informatization process of Chinese SMEs, continue to innovate, continue to introduce more and better services, build intelligent Chinese enterprises, and achieve smart entrepreneurs!

What is the role of concrete protective layer in the use of steel truss floor?

The concept of concrete protective layer: in reinforced concrete members, in order to prevent corrosion of steel bars and ensure that the steel bars and concrete are firmly bonded together, there must be a concrete protective layer of sufficient thickness outside the steel bars. The minimum distance from the outer edge of the reinforcement to the concrete surface is called the thickness of the protective layer.

Academician of Chinese Academy of Engineering: Vigorously develop steel structure buildings, steel structure buildings are most suitable for building industrialization

From the 8th to the 9th, the annual work meeting of the Steel Structure Expert Committee of the China Construction Metal Structure Association was held in Wuhan. At the meeting, three academicians of the Chinese Academy of Engineering-Professor Shen Zuyan of Tongji University, Professor Dong Shilin of Zhejiang University, and Professor Mark Jian of Guizhou University jointly suggested, Vigorously develop steel structure buildings to resolve the current serious excess steel production capacity.
