evaluation meeting invited Professor He Mingxuan, chief expert of China Baowu Iron and Steel Group Co., Ltd., as the team leader, Professor Xue Suduo of Beijing University of Technology, Huo Wenying, chief engineer of China Architectural Design and Research Institute Co., Ltd., Fu Lijiazheng, director of Shuzhi Transportation Engineering Research Center of China Merchants Chongqing Transportation Research and Design Institute Co., Ltd., and Hou Xianju, chief engineer of Xuzhou Zhongmei Baijia Heavy Steel Technology Co., as the senior engineer. The meeting was presided over by Li Qingwei, secretary general of the association. Cai Dongbo, chief engineer of the seventh engineering co., ltd. of the first public administration of China, Chai Shaoqiang, director of the technology center, and Guan Yu, associate professor of Chang 'an university, attended the meeting. At the

meeting, Feng Tianchu, chief project engineer of the 7th Engineering Co., Ltd. of the First Public Administration of China, reported on the project research background, key innovative technologies and application of achievements on behalf of the project team. The evaluation experts reviewed the technical data, and after inquiry and discussion, they believed that the main innovative achievements of the project team for the research and development of the integral hoisting technology and key equipment of the space grid structure were as follows:

1. The integral hoisting construction technology of the space steel grid based on the integrated technology of BIM analysis was proposed;

2. A device for hoisting and hoisting beams of the steel grid was invented, and the integral hoisting of the steel grid was realized;

3. Through the development and application of a number of software systems, the spatial grid structure is formed to predict the installation and construction safety monitoring technology.

The research results have been demonstrated and applied in the "ship-shaped" pipe truss project of Xiangtan Tourist Service Center and the roof steel grid project of No. 8 Gymnasium in Zhongmou County. The economic and social benefits and environmental benefits are remarkable, and it has broad application prospects.

Expert Group believes that the results reached the international advanced level.

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.
