The development of light steel structure housing needs multi-party support.
-- visiting director of steel structure of China institute of architectural sciences, Dr. Wang minggui.
Not long ago, this newspaper published a series of reports on the enactment of the technical regulations on the structural housing of light steel (JGJ209) (hereinafter referred to as the "regulations"), which attracted wide attention in the industry. The regulations will be officially implemented on October 1 this year. As the first technical specification for light steel structure housing in China, why should we introduce the regulation? How can the code be better implemented? To this end, our reporter interviewed one of the editors of the "regulations" -- the director of the steel structure of the Chinese academy of architectural sciences, Dr. Wang minggui.
Reporter: what is the background and significance of the regulation?
Ming-gui wang: our country the first about the specification of the steel structure residence, the regulation on April 17, 2010, promulgated by ministry of housing and urban-rural development, the "discipline" is a summary and analysis of the steel structure housing project practice for many years in China and done a lot of scientific experiments and, on the basis of investigation and research, put forward an accord with China's national conditions, consistent with the current national standard of light steel structure housing the new system. It specifies the function of the light steel structure residential building and performance, gives a material of light steel structure housing standards, design, construction and acceptance of the technical requirements and use and maintenance of standard management principles. The promulgate of the regulation will not only regulate the engineering practice of light steel structure residence in China, but also provide guidance for the enterprise to develop new type of wall material and building energy saving system.
Reporter: what is the characteristic of light steel structure housing system? What is the status quo?
Ming-gui wang: light steel structure residence is a kind of new construction system, involving the material is a new building materials, the design method is' construction, structure, equipment, construction and decoration integration "of the new method, comprehensive building system is a very professional. Our country in recent years, the steel structure housing engineering practice showed that various steel structure residential structure system, has introduced from abroad the cold-formed thin-wall steel low-rise residential buildings, useful also ordinary hot-rolled h-beam structure of multi-storey and high-rise residential buildings. But building materials and the requirements of the application technology to meet the residential function, performance and steel structure supporting the palisade less varieties of materials, poor quality, science and technology content is not high, restricting the development of steel structure residence. The one-sided understanding of steel structure residence is steel structure, ignoring the function of residential construction, cannot solve the matched with steel structure, satisfy the residential function, has the safety, durability, practical and technical problems of retaining structures and the result is not sustainable. In addition, enterprises do not form an industrial chain. 'production, learning, research' disconnection, 'technology, industry, trade' is not unified. The researchers who are engaged in the development of technology can not find engineering practice in the market, and take the 'golden rice bowl' begging, the technology can not be tested and perfected, so that the research and development can not proceed. In view of this situation, the ministry of housing and urban-rural development has instructed the relevant departments to compile the regulations, so that the r&d personnel and the market can integrate into the industrial system.
Reporter: what do you suggest for better implementation of this code?
Good ming-gui wang: in order to implement the "regulations", complete set technology, guide the scientific development of steel structure residential standard steel structure residential construction market in China, ensure the quality of the steel structure housing project, I have three Suggestions:
First, the establishment of light steel structure residential design construction integration qualification. Light steel structure housing is a new type of building system based on the special system of enterprise development and the design, construction and acceptance of concrete works according to the regulations. In accordance with the provisions of the "regulations" article 4.1.2 is light steel structure housing should be in accordance with the integration of construction, structure, equipment, and decoration design principle, and should according to form a complete set of comprehensive design on the basis of building systems and products. The establishment of enterprise 'integration qualification' will benefit the scientific development of light steel structure housing.
Second, the establishment of the steel structure residential enterprise alliance. The scientific research unit and the enterprise are organized, "produce, learn, grind" to combine, draw a bridge, information share, joint attack, common development. The goal is to develop new energy-saving wall and low-carbon building system, promote the industrialization of housing and promote the technological innovation of the construction industry.
Third, the establishment of a steel structure housing technical expert group. The technical control of the steel structure housing project to ensure the reasonable selection, design and construction quality; Technical advisory services for steel structure residential technology development, guide the steel structure residential or product 'safe application, economic rationality, advanced technology, ensuring quality'; The company applies for the evaluation of the construction integration qualification of light steel structure residential design, and provides reference for the relevant government departments.
In the case of building curtain wall, curtain wall engineering design and construction are the curtain wall enterprise and is essentially private enterprises' integration 'implementation of, the government formulated the curtain wall standard and the enterprise level of qualification, play to their innovation ability, the stone material to hang on to a few hundred meters tall building outside wall, withstand the test of time, earthquakes and hurricanes, their successful practices can be for reference.
For the steel structure housing technology development, will promote China's residential building material innovation and change the way of content of science and technology of construction technology and construction, although it is less in the market, but the progress of science and technology, marked the country building marks the building from the construction site to the factory, is part of realizing industrialization and modernization in our country. In the initial stage of light steel structure housing, the industry association should give the enterprise support and help to make the light steel structure residential technology healthy development.
