Residential Housing Industry Modernization and Steel

Steel News Hainan: Residential Housing Industry Modernization and Steel

Steel News Hainan sum refers to the residential housing industry and related parts production, sales and business activities, the core product is the development of residential industrialization, aimed at improving the quality of residential buildings and thus promote the development of related industries. Housing Industry Modernization is to use modern scientific and technological means to establish a standardized, industrial and marketization of housing production system in order to support large-scale socialized production and supply as the main way to improve the quality of residential buildings and promote the development of housing industry. Housing Industry Modernization is mainly reflected in: the production of industrialization. That dwelling used materials, components and products in the factory can be fast, mass production, and has significant technological content.
 
Circulation specialization. Residential construction and supply industry isolated dwelling used materials, components and products and so have specialized circulation system.
 
Operating scale. By industry group and industry base gathering capital, joint ventures, the scale of operations.
 
Consumer personalization. It has high adaptability industrial structure by directing individual consumption, so the housing industry to meet the diverse, serialization and personalized environment requirements.
 
Housing Industry Modernization and development of productive forces is the inevitable trend of technological progress, which includes the modernization of residential buildings and industrial structures of the two systems. Between these two systems, modern architecture is a necessary condition for modernization of housing industry, no modern architecture, and certainly no modern housing industry. Compared with the existing structure, steel structure is one of the most consistent with industrial production methods, it is easiest to implement standardized design, components and parts production factory, social product supply, construction and assembly mechanization , market consumption series. And seismic behavior of steel is very good, but also re-use, environmentally friendly. China's steel output has been three consecutive years of more than 100 million t, steel varieties are relatively complete, the design standards of basic facilities, professional processing and construction of power has begun to take shape. On the other hand, a wide range of large residential construction, long duration, is the growth of the national economy. If we can promote residential construction steel, building industry, new technologies, new materials, the development of industry and improve the overall level of the new system can play an important role in promoting, but also the development of the metallurgical industry can play a catalytic role. Housing construction in developed countries has been widely used in steel, is expected in the 21st century residential building will be the century of the rise of steel.
 
1 foreign concept development and trends in the housing industry's first first proposed in the 1970s by the Japanese, this time, the product has scale industrialization of residential, residential construction industrialized developed countries gradually transition from quantity to quality improvement development direction. After the 1980s, the housing industry in developed countries to increase investment in science and technology, began to focus on the residential function and the direction of diversification, the formation of a number of large enterprise groups, a comprehensive industrial base and open technology standards, has reached a basic mature and stable development of the state, is moving to personalized, high environmental quality. USA Residential annual output value accounted for GDP25% ~ 30%, in the development stage.
 
However, residential construction in developed countries in the steel housing is not much, according to the American Institute of Steel Construction 1998 data provided by it: from 1993 to 1997 were built steel residential 1.3,40,55,7.5,9.5 Wan sets, respectively, accounting for 1.7% of the residential buildings of the total units, 29%, 41%, 57%, 7.0%, and most of them single-block single-family or two-family of low-rise buildings. Although the number of Japanese steel buildings up to, but in a high-rise building, represented only steel steel housing construction area of ​​about 20%, most of which are low-rise and single-family homes, four or more layers of steel housing is less than 1 one reason% to 2%. is the high cost of pure steel housing. According to our research traitor, the cost of steel and concrete composite structure is flat. However, we believe that good performance steel housing, a slightly higher price is reasonable, can not ignore the pursuit of price and quality, to a fine.
 
First Author: Wang Minggui male born in May 1956, Dr. Research Associate 2 development and trends from the housing industry, the housing industry foundation is weak our country, a Subsidiary of modern technology and product development started late, in the primary housing industry stage. Main features: the housing industry is still labor-intensive, less residential investments in technology, standardization system has not been formed; low labor productivity, per capita long-term completion of the area more than 20 m2 wandering, while the United States and Japan about 100m2. Scientific and technological progress contribution rate of only 25%, while the United States and Japan were more than 50%; low level of industrialization, only 15%, than the United States, Japan, a far cry from 70% to 80%; residential component, product support poor series products less than 20%. in short, China's housing industry is basically in "pre-industrial" decentralized backward, handicraft workshop, contractor team and guerrillas. This situation, it is difficult to adapt to China, saying the benefits of growth in housing demand and make the housing industry requirements to become a new economic growth point.
 
Since the reform and opening up, China's rapid development of housing construction in 1999 compared with 1978, the National Urban per capita living space increased from 3.6m2 9.78ml recent years, urban housing completed in an area of ​​3 to 400 million m2, equivalent to Canada National total housing. Residential annual output value of 600 billion yuan, accounting for about GDP10%, shows that China's housing construction is in the take-off stage. 1999 economic growth of 7.2% in residential pulling 1.5 percent. In 1999, China's total population of 126.7 billion and is expected to reach 1.6 billion by 2030, the urban population from the present 30.9% to 60% of the population growth and urbanization will inevitably lead to higher demand for housing. In order to meet people's growing demand for our housing, speed up housing construction from extensive to intensive, to promote the modernization of housing industry, improve the quality of housing, in 1999 the State Council forwarded the eight state ministries and commissions on promoting the modernization of housing industry, improve housing quality several opinions (SCS No. 72), made it clear to the development and introduction of advanced residential building systems and complete sets of engineering technology to improve the level of industrialization of residential construction and standardization, energy efficient, improve housing quality, so as to form industrial chain, promote the development of related industries, the formation of sustainable economic growth. To implement the SCS 199 972 documents, the Ministry of Construction and other four ministries jointly issued on elimination of outdated equipment in a residential building in the notification in December 6, 1999>, which is included in the solid clay gradually banned products, reflects the government in the housing industry in the policy-oriented.
 
Obviously, steel is a form consistent with the requirements of the housing industry, the status quo China's steel production and steel market, the Ministry of Construction and the former State Bureau of Metallurgical construction steel Technical Coordination Group to develop a national construction steel industry, "15" plan and the 2015 development plan, and strive in the "fifth" period of China's construction steel steel consumption up to 3% of the country's steel output in 2015 to reach 6% of construction steel to promote the application and development of China's construction industry new technology, new materials, and improve the overall level of development of the new system can play an important role, while the development of the metallurgical industry can also play a positive role in promoting.
 
3 steel residential road of industrialization development of steel housing, industry should take into goals. First, the residential parts as far as possible the industrial production, while industrial production is the premise of standardization, standardization achieved by means industrial production is "efficiency" means residential construction site shift from the factory, which means the supply of residential parts of society. Thus contributing to improve product quality management and is conducive to building the management team and improve labor productivity, it is conducive to technological innovation and application of modern science and technology, optimize the allocation will help drive the development of related industries and resources. Housing Industry Modernization is the science and technology of the housing industry, which is a measure of an important symbol of national progress and social development.
 
Development of steel structure residential system should be market-oriented. Residential is business, and is a special commodity, in particular its price is expensive, one-time purchase, lifetime consumption, generation to generation. Require both high residential quality, durability, low maintenance, also requires the construction costs must reflect market conditions, can not have too much difference with other systems houses. Be inexpensive, does have a certain degree of difficulty. On this issue there is no ready-made direct reference to foreign experience, because foreign steel housing is generally lower layer (layer 1-2), while China's large population, less land resources, should be developed with Chinese characteristics, high-rise or multi-layer steel residential structure. At present, the development of steel housing, with the market price to "standards", must take a gradual path of development, make full use of the existing system has a mature and industry trend, and gradually develop the market, guide consumption, neither anxious We can not wait on the sidelines. By a small number of demonstration projects solve one subsystem issues, lessons learned, and gradually developed for the development of complete sets of technology.
 
Development of steel structure residential, business is subject. In a market economy, enterprises organizational model, philosophy, strategy, product structure and process innovation mechanism for determining the level of residential and industrial development. Industrial pillars of enterprise, which is the most dynamic market economy fundamental part. Currently, the housing industry is the main business of real estate development enterprises. It started before the national scientific and technological achievements conversion project, mostly by the government to contribute money, passive participation of enterprises, in 2000 well-off urban and rural residential technology industry project is the expert study based on the results and new product demonstration area in the country carried out a trial by the market test of its maturity, whether the promotional value, so that the development of enterprises play an important role. Developers must look at the market, but also depends on the policy-oriented. In the 21st century, China to improve housing quality and comprehensively promote the modernization of housing industry, the authorities have introduced and gradually introduced a number of measures and guidelines, developers should closely follow the policy direction, engage in technological innovation, production and integration of scientific research, fight foundation for development, to seek new economic growth point. Currently, residential products business is relatively positive, the market there have been many residential products, such as H-shaped steel, special steel, non-clay bricks, wall panels and so on. Residential real estate development enterprises should extend enterprise products and alliances, from project development to corporate brand.
 
Development of steel housing, the government is leading. Government departments should develop the housing industry and policy-oriented macro-objectives, and depending on the level and the status of the housing industry development of local economic development, it is determined to promote the housing industry, improve the quality of residential work steps. Application of economic levers, through taxes to restrict the use of inferior products, while encouraging the use of new technologies and materials; application of basic research funding traitor, choose a topic, research organizations, and improve the preparation of standards and norms in the series; organize demonstration projects, a step by step solve one or two problems, and gradually promote the related art; support a number of technology-intensive enterprises, the development of housing components and supporting technology, the development of the building materials market, the formation of local industries.
 
4 Conclusion steel housing steel is not simply to build houses, but in the industry as the goal, market-oriented, in order to improve the quality of housing for the target of huge systems engineering. On the one hand, good steel performance, easy to industrialization, and promote the development of China's metallurgical industry; on the other hand, is a special residential consumer goods of the people, demanding residential function, long service life. Study based on the development of steel housing is in line with the new multi-storey residential development research Zhou Xuejun Steel System (Shandong Institute of Technology built, Jinan 250014) species new green steel robbery configuration system. This article describes the system configuration of residential robbery steel composition, advantages and disadvantages of the main node structure raises several important questions for future research and development should be noted, for peer study time.
 
BOLTED is one of the Ministry of Construction in the construction industry focus on the promotion of ten new technology, which is widely used in homes, office buildings, warehouses, factories, theaters, stadiums and even hangars and other construction projects, according to the information reported, currently light steel construction market in the United States accounts for about 75%, while in Japan the new building, 1-4 storey building most of the use of light steel structure system. World countries are optimistic about the lightweight steel market and concentrate its efforts on exploration and development of China's current annual steel output exceeded 100 million t, ranking first in the world, and variety, size and quality of steel can close and reached the international advanced level, so development and application of light steel structure, with a very broad prospects. Meanwhile, the current and future within quite a long time, housing demand will be in one of the largest building products, will therefore be used in residential light steel structure to form a new multi-storey residential steel structure system, will greatly promote the housing industry development, improve the technological content of the housing industry.
 
And the housing industry needs to adapt to a wide range of people building requirements are higher and higher, the concept of ecological architecture and green building has been popular. Green building refers to the so-called low-power, low consumption, no pollution, versatile, recyclable building and steel construction is to meet these requirements, the movable steel removable, recyclable products, and therefore residential steel buildings It is a green environment-friendly building.
 
The composition and characteristics of the traditional system of multi-storey residential steel 1 steel housing system architecture housing (brick structure, concrete structure) are very different, it has a main body steel structure system, the peripheral wall and the inner compartment wall systems, floor (house) panel system components.
 
Steel system has a multi-storey residential energy conservation, rapid construction, favorable seismic, environmental protection and adaptation to meet the obvious advantages of industrial production, with its outstanding features are: the steel structures for residential buildings can take advantage of the good ductility of steel, plastic deformation ability, excellent seismic performance, etc., which greatly improved the safety and reliability of the housing.
 
Residential steel buildings than traditional buildings to better meet the requirements of large bays separated by flexible, better able to meet the needs of modern living life to meet the needs of modern residential market, and by reducing the cross-sectional area of ​​the column and the use of light pursuing a form of housing industry modernization beneficial to the construction industry and technological progress, improve labor productivity, improve project quality, and promote the development of related industries, but steel housing industry modernization is a level many industries involved in the development of large systems engineering, parts can not meet the relevant function of living is the key constraint steel residential development, the main reason is the price limit, which requires a process of exploration and research traitor, but also a process of change in consumer attitudes. Housing industry modernization is the only way, in the 21st century steel housing will have a big development, but the opportunities and challenges.
