"Green Assembly" as the theme of industry development Lightweight steel structure is the last word

As a brand event of the industry, the “Summit Forum” of the steel structure industry has been successfully held for three sessions, and has received the recognition and support of the majority of colleagues, and has achieved good results. This session draws on the successful experience of the previous three sessions, closely follows the industry's hotspots, and focuses on "steel structure construction-green and healthy development of assembly" as the theme, focusing on how steel structure construction can achieve green energy saving and assembly To promote industry transformation and upgrading. Chen Tianyi, chief engineer of the Guangdong Provincial Department of Housing and Urban-Rural Development, Vice President of Xi'an University of Architecture and Technology, member of the National Committee of the Chinese People's Political Consultative Conference, Chairman of China Building Metal Structure Association, Hao Jiping, Executive Vice Chairman of China Steel Structure Association, and Deputy Secretary of China Building Metal Structure Association Mr. Chang, the president of the Construction Steel Structure Branch, party defense and other industry experts, leading enterprises and leaders of major associations made special reports and shared successful experiences.

Wang Shitong, chairman of the Guangdong Steel Structure Association and professor of South China University of Technology, said that green buildings are mainly energy-saving and environmentally friendly. The steel structure proposes a structural arrangement, which is less expensive and more useful, and provides the largest structural bearing capacity with the least structure, that is, the lightweight steel structure. Design is the last word. Evaluate the steel structure industry, including design and construction. Construction includes manufacturing and installation. The rest of the steel structure must begin with design.

Steel structure is a typical green building. The space for steel structure assembly building is huge.

    Hao Jiping, president of the China Association of Building Metal Structures and vice president of Xi'an University of Architecture and Technology, said that we now actively promote the industrialization and modernization of construction, which is to follow the path of industrialization. The new type of industrialization of buildings can achieve energy conservation and environmental protection in buildings and maximize the value of the entire life cycle. Sustainable new construction style. So we said that we have to transform and upgrade and go green buildings. The steel structure is a typical green building. The materials can be recycled and reused. It has good seismic performance and sustainable development. The concept of recycling is reflected in the entire design, construction, demolition and other processes of our steel structure buildings, which are all green. Therefore, we say that steel structures are more suitable for the current industrialized production and assembly-type building development and demand, and also more in line with the development direction of our country.

Chen Tianyi, chief engineer of the Guangdong Provincial Department of Housing and Urban-Rural Development, said that steel structure is one of the main forms of assembling buildings. At this stage, in areas with good economic development, including Guangdong, Jiangsu, Zhejiang, Shanghai, These big cities like Beijing should account for about 20%. During the 13th Five-Year Plan period, the country will increase its investment by 400 billion yuan, and at 15%, it will have close to 300 billion yuan and 290 billion yuan of investment. The space for steel structure assembly buildings is huge.

Steel and composite structures should develop in synergy

    Hou Zhaoxin, secretary general of China Steel Structure Association and technical director of China Metallurgical Construction Research Institute, said that we are building green buildings with high cost performance. Compared with the structure of the shear wall, what are the shortcomings, and the shortcomings should have advantages. We want to build green buildings, and the idea is an idea that people can accept. In this case, we are developing the MCC Steel House system and are working hard to solve this problem.

Luo Chiyu, chief engineer of Guangdong Architectural Design and Research Institute, said that in addition to steel structures, composite structures can also be developed in combination with steel structures at the same time, a form suitable for our national conditions and local characteristics. In addition, innovative ideas to develop prefabricated steel structures are still based on the concept of building system integration. Instead of making a steel structure, they must work from an architectural system and an integrated perspective to rewrite the prefabricated steel structure system. In addition, the conventional modular construction is usually multi-level. If you want to develop to multi-level, especially high-level, do you need to have some innovation in the structural system?

    Liu Yanjun, deputy dean of the Design and Research Institute of Zhejiang Luzhu Integrated Technology Co., Ltd. said that in the process we are doing, many parties consider information methods, including our factories, including our design, from the program to our deepening, to our The standard build, including our standard build library, makes the platform for the entire system. For example, your industrialized building, prefabricated building, how well you standardize, how to split it up, this poses a great challenge to us.

Attendees carefully listen to expert reports

The forum has achieved expected results. Experts and scholars discussed the healthy development of prefabricated steel structures with the theme of “Steel Structure Buildings—Green and Healthy Development of Assembly”. The meeting also raised the development of prefabricated buildings as a national strategy. How to calculate the assembly rate of prefabricated steel structures and why high strength bolts should be used for prefabricated steel structures are discussed. At the same time, the forum proposed that prefabricated construction should not be carried out across the board. It should be adapted to local conditions and materials according to local conditions. In addition, it should also learn from some foreign experiences to find innovative solutions for steel structure construction systems suitable for Chinese characteristics.

    Since its establishment in 2009, the Guangdong Steel Structure Gold Award (referred to as the "Guangdong Steel Award") has been selected for nine sessions. A total of 104 "Guangdong Steel Award" projects have been selected, including 175 awardees, including 3 comprehensive awards and 5 design awards. , 99 construction awards. At the same time, a total of 940 outstanding technical personnel were selected. The "Guangdong Iron and Steel Award" has two characteristics: 1. The steel tonnage of the project is not particularly emphasized, and the award-winning project is based on the level of technological innovation, quality and accuracy; 2. The "Guangdong Steel Award" is divided into: , Manufacturing) two categories. The construction category is not classified, and the design category is divided into first, second and third prizes.
