ASEAN steel demand soars, overseas Chinese leaders look forward to building a bridge for Chinese steel companies to go global

"At present, there are three major railways in Southeast Asia that are under construction or have been included in the construction plan, which has a huge demand for steel. China's steel has technological and financial advantages, and it is possible to consider 'going out' to invest in ASEAN. Overseas Chinese and overseas Chinese are willing to In this process, it is a bridge for Chinese enterprises." Deng Lianghui, president of Laos Guangxi Association, said in an interview with a reporter from China News Agency in Nanning recently. From January 12 to 16, the Fifth Session of the Eleventh CPPCC Guangxi Zhuang Autonomous Region was held in Nanning. Deng Lianghui and many other ASEAN leaders attended the meeting. According to data released by the Southeast Asian Iron and Steel Association recently, since 2016, the steel consumption of ASEAN countries has grown strongly, and the steel demand of Vietnam, the Philippines, Indonesia, Thailand, and Malaysia has exceeded expectations, and the consumption has increased by more than 20% year-on-year. As the main importer of steel from ASEAN countries, in the first three quarters of 2016, ASEAN imported 28.36 million tons of steel from China, a year-on-year increase of 20%. "The China-Laos Railway has now fully started. The construction of the railway, the construction of the station and some commercial properties in the future will require a large amount of steel. Although Laos has some small-scale joint venture steel plants with overseas, most of them still need to rely on imports. Deng Lianghui said that for a long time, China's foreign aid infrastructure construction projects, technology and steel are basically exported from China, and the cost of material transportation is relatively high. "Instead of that, why don't Chinese steel companies consider setting up factories directly in ASEAN?" Chen Hongbing, vice president of the China All-China Federation of Small and Medium Metallurgical Enterprises Chamber of Commerce, also said in an interview with a reporter from China News Agency that China's current steel production capacity has reached 1.25 billion tons. Overcapacity, China will reduce crude steel production capacity by 100-150 million tons in the next five years. "The economic development in the ASEAN region continues to improve, and the steel demand potential is huge. As China's largest steel exporter, it is very necessary for China and ASEAN to carry out cooperation in the steel industry." Tang Jianxiang, president of the Cambodia Guangxi Chamber of Commerce, agreed. He said that Cambodia is currently implementing the "Cambodia Industrial Development Policy from 2015 to 2025. Chinese steel companies should seize the opportunity to invest and set up factories in ASEAN countries." and business environment system have rich experience and unique understanding. When Chinese enterprises invest and set up factories overseas, overseas Chinese can become an important way for them to understand the situation of the investing country, and play the role of platform and media. Deng Lianghui also said that ASEAN countries themselves have relatively rich iron ore resources. Chinese-funded steel companies investing in ASEAN can not only effectively utilize local resources, but also promote the development of the local steel industry. "As overseas associations and chambers of commerce, we can Assist Chinese enterprises to do some preliminary work and research to help them further explore the investment country environment. Deng Lianghui believes that Guangxi itself has certain advantages in steel, industrial manufacturing and automobile industries. "Southeast Asia is a large market with a population of 650 million, accounting for half of China's population. Relevant enterprises in Guangxi should take advantage of their geographical advantages to actively cooperate with relevant industries in ASEAN countries. It is understood that in recent years, Chinese steel industry giants have stepped up the pace of "going out", and went to Nigeria and other places to invest and set up factories. However, in ASEAN countries, the pace of "going out" of Chinese steel enterprises has been slightly slower. "China and Thailand are developing Cooperation in the field of steel has natural advantages. Li Mingru, chairman of the Guangxi Federation of Thailand, who attended the Guangxi CPPCC meeting, said that it has been the 41st anniversary of the establishment of diplomatic relations between China and Thailand, and the two countries have very close relations and exchanges in terms of geographical location and history. Now the Federation of Industry and Commerce under the Guangxi Federation of Thailand has Begin to pay attention to the development of the steel field, and the staff of Guangxi Construction Engineering Group are also promoting this aspect.” Regarding the prospect of Sino-Thai cooperation in the steel field, Li Mingru believes that “the prospect is very optimistic, and cooperati

Steel structure market analysis and development prospect

Market Analysis my country's construction steel structure started early, industry standards and specifications are becoming more and more perfect, industry talents (including design, installation, construction) have gradually formed a scale, and some high-quality companies have begun to undertake overseas projects. According to the "2015-2020 China Steel Structure Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" released by the Prospective Industry Research Institute, since 2000, my country's steel structure industry has entered a stage of rapid development, and the output of steel structures has increased from 8.5 million in 2002. tons, increased to 35 million tons in 2011, with an average annual compound growth rate of more than 15%, and the output in 2012 was about 39 million tons. my country's spatial steel structure is widely used, accounting for a large proportion of steel structure applications, mainly used in urban public buildings such as large stadiums, theaters, airports, and railway stations. By 2012, the market capacity of space steel structure is about 43 billion yuan. Steel structure buildings have the advantages of earthquake resistance, light weight, and low environmental pollution, which are in line with the direction of building energy conservation and environmental protection. In developed countries such as the United States and Japan, the steel structure building area accounts for more than 40% of the total building area, while in China, this proportion Only about 5%. Therefore, the promotion of steel structure buildings will greatly expand the demand market of the steel structure industry, and this market has great development space in China. Development prospects Steel structure development: three major areas should be paid attention to. According to the development of the industry, Liu Jun believes that the development of the three areas of offshore oil engineering equipment, steel structure housing, and steel structure bridges should attract the attention of the relevant national authorities. And policy encouragement can fully achieve the goal of industrial doubling. Liu Jun pointed out that the output of offshore oil will reach 100 million tons in 2015. The goal of marine engineering equipment enterprises is to provide a large amount of equipment for the mining of deep seas ranging from 1,500 meters to 3,000 meters. The industrial level and scale must be improved; Environmental protection, energy saving and emission reduction and circular economy policies, its industrialized and standardized steel structure residential products have a broad and unlimited market space; at present, less than 1% of the 590,000 highway bridges in the country are steel structure bridges, the railway system is developing rapidly, and new lines are built. With bridges instead of roads, 80% of them are prestressed reinforced concrete bridges. While steel structure bridges account for 41% in Japan and 33% in the United States, it can be seen that there is still a big gap between the market demand and industrial development of steel structure bridges in my country and developed countries. China's steel structure industry has developed rapidly in the past 10 years, and has become the world's largest steel structure country with the largest amount of steel structure, the strongest manufacturing and construction capacity, the largest industrial scale, and the largest enterprise scale. Steel structure enterprises: Pay attention to the development of the "Twelfth Five-Year Plan" Liu Jun pointed out that the successful construction of major steel structure projects in various places shows that my country's comprehensive steel structure technology level has reached the international advanced level. However, there is still a big gap between my country's steel structure industry and developed countries in terms of informatization, automation, standardization, scientific research and innovation. 2011 is the first year of the national "Twelfth Five-Year Plan". Relevant national ministries, industry associations, enterprise groups, and steel structure enterprises are all conducting research and analysis of the market and future development trends. The National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Science and Technology are also studying the determination and planning goals of relevant strategic new industries. For industries with international advanced level, strong independent innovation ability, strong international competitiveness and can occupy more markets, they will be included in the planning and given. Support and support policies. Opportunities are also challenges. Whether my country's steel structure industry can reach a higher level and scale, the development during the "Twelfth Five-Year Plan" period is very important. Liu Jun said that after investigation and research, and after listening to the opinion

The Development Situation and Trend of Building Steel Structure in my country

The construction steel structure industry mainly refers to the domestic enterprises engaged in the production, processing and installation of construction steel structures and the production enterprises of auxiliary products. With the acceleration of the country's industrialization and urbanization, and the extensive use of modern construction technology, this industry has developed rapidly. . According to incomplete statistics, by the end of 2010, there were more than 10,000 steel structure processing and manufacturing enterprises of various scales in the country, and more than 400 enterprises with first-class steel structure professional qualifications. There are 39 large-scale steel structure enterprises with an annual processing capacity of more than 50,000 tons. These enterprises lead the trend of the industry, and gradually move towards scientific management, focus on quality, and be good at absorbing and digesting today's international advanced technological achievements. In some technical fields, they have reached or exceeds the international advanced level. The newly built Olympic Bird's Nest, the new CCTV site, Shanghai Global Center and other steel structure building products have become the representative works of this industry. During the "Twelfth Five-Year Plan" period, my country's iron and steel enterprises and iron and steel manufacturing industries were supported by active industrial policies. , will show a sustainable and healthy development trend. According to preliminary statistics, my country's steel output in 2011 will still maintain a certain growth level, and China will still be the main market for steel, steel structure and steel products. , The relatively low cost of construction will still occupy a considerable proportion in urban construction and infrastructure construction in the next five years. With the improvement of urban functions, the shortage of land resources and the popularization of super high-rise residential buildings, the construction steel structure market will remain relatively high. large scale of growth. From the perspective of market prospects, the country will invest heavily in processing infrastructure construction, the application of building steel structures will be inclined to energy, infrastructure, high-rise residential and other fields, the proportion of steel structures in highway and railway bridge construction will increase, urban subway and light rail projects, overpasses , viaducts and other urban public facilities will increasingly use steel structures. With the popularization of the concept of green and environmentally friendly buildings, the design specifications and supporting technologies for steel structure residential buildings are becoming more and more mature, and the scale of steel structure buildings will increase. The research and development and promotion of residential buildings will have a positive impact.

Development history of steel structure

Although China had outstanding achievements in iron structures in the early days, due to the constraints of the feudal system for more than 2,000 years, science was not developed, so it stayed at the level of iron buildings for a long time. It was not until the end of the 19th century that my country began to adopt modern steel structures. After the founding of New China, the application of steel structures has been greatly developed, far exceeding the past in terms of quantity and quality. The floor of the light steel structure is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, supports, connectors, etc. The materials used are oriented strand board, cement fiberboard, and plywood. Each square meter of these lightweight floors can bear a load of 316 to 365 kilograms. The number of steel structure buildings indicates the economic strength and economic development of a country or a region. After entering 2000, my country's national economy has grown significantly, its national strength has increased significantly, and its steel production has become a world power. Construction is gradually increasing in economically developed areas. Especially around 2008, under the impetus of the Olympic Games, there was a boom in steel structure buildings, and the strong market demand promoted the rapid development of steel structure buildings. A large number of steel structure venues, airports, stations and high-rise buildings were built. Among them, some Steel structure buildings have a world-class level in production and installation technology, such as the Olympic National Stadium and other buildings. After the Olympic Games, steel structure buildings have been popularized and developed continuously. Steel structures are widely used in buildings, railways, bridges and houses. There are tens of thousands of steel structure enterprises of various sizes, and the world's advanced steel structure processing equipment is basically complete, such as Multi-head multi-dimensional drilling machine, steel pipe multi-dimensional intersecting wire cutting machine, corrugated plate automatic welding machine tool, etc. And now the processing and production level of hundreds of steel structure enterprises has reached the world's advanced level, such as steel structure manufacturing super and first-class enterprises. In recent years, the annual steel output has reached more than 600 million tons, and the steel varieties can fully meet the needs of construction. Steel structure design specifications, steel structure material standards, steel structure engineering construction quality acceptance specifications, as well as various professional specifications and enterprise construction methods are basically complete. The downstream industry of steel structure has a greater traction and driving effect on the development of the steel structure industry, and their demand changes directly determine the future development of the industry. 1. The upstream industry of steel structure is the raw material supply industry such as steel The steel industry is the material basis for the development of the steel structure industry, and the technological progress of the steel industry has created favorable conditions for the application of steel structures. Some large enterprises in the domestic steel industry have started the research and development of steel varieties and technologies for building structures, and have successively developed high-strength steel and steel for fire resistance, weather resistance, seawater resistance, laminar tear resistance, and low temperature resistance, as well as H-beam, high Performance color-coated steel plates, cold-formed steels, etc., have laid a good application foundation for the development of the steel structure industry. 2. The impact of upstream and downstream on the industry The upstream of the steel structure is mainly the steel industry, and the price fluctuation of steel products directly affects the procurement cost of the industry. On the whole, the upstream industry is basically a competitive industry, producing various types of steel plates, steel pipes, section steels and other steel materials for steel structures. Among them, H-beams and medium and heavy plates are the most commonly used products in steel structure buildings. Industry Insights Research Data In 2011, the crude steel output reached 696 million tons, and the output was relatively saturated. The raw materials required for the production of steel structures could obtain a stable supply. The downstream industries have a greater traction and driving effect on the development of the steel structure industry, and their demand changes directly determine the future development of the industry. Due to its comprehensive advantages such as high strength, light weight, good seismic performance, high degree of industrialization, short construction period, strong plasticity, energy saving and environ

What are the components of a single-storey steel structure workshop?

A single-storey steel structure workshop is generally a space system composed of roof structures, columns, crane beams, brake beams (or brake trusses), various supports, and wall frames. These components can be divided into the following categories according to their functions: (1) The transverse frame is composed of columns and the roof trusses or roof beams supported by it. It is the main load-bearing system of the single-storey steel structure workshop. Snow loads and vertical and lateral loads from cranes and transfer these loads to the foundation. (2) Roof structure The structural system that bears the roof load, including beams, brackets, intermediate roof trusses, skylight frames, purlins, etc. of the transverse frame. (3) The support system includes the support of the roof part and the inter-column support. On the one hand, it forms the longitudinal frame of the single-storey steel structure workshop with columns and crane beams, and bears the longitudinal horizontal load; on the other hand, the main load-bearing system is The individual plane structures are connected to form the overall structure of the space, thereby ensuring the rigidity and stability necessary for the steel structure of the single-storey factory building. (4) The crane beam and brake beam (or brake truss) mainly bear the vertical and horizontal loads of the crane, and transmit these loads to the transverse frame and the longitudinal frame. (5) The wall frame bears the self-weight and wind load of the wall. In addition, there are some secondary components such as ladders, walkways, doors and windows, etc. In some single-storey workshop steel structures, there is also a working platform due to the requirements of process operation. 1. Column grid layout Column grid layout (layout of column rows) is to determine the arrangement of the load-bearing columns of the single-storey steel structure workshop on the plane, that is, to determine the grid formed by their longitudinal and lateral positioning axes. The span of the single-story factory building steel structure is the dimension between the longitudinal positioning axes of the columns, and the column spacing of the single-story factory building steel structure is the size of the columns between the lateral positioning axes. 2. Temperature expansion joints Temperature changes will cause structural deformation, resulting in thermal stress on the steel structure of the workshop. Therefore, when the plane size of the factory building is large, in order to avoid excessive temperature deformation and temperature stress, temperature expansion joints should be set up in the horizontal and vertical directions of the steel structure of the factory building. The arrangement of thermal expansion joints depends on the longitudinal and transverse lengths of the steel structure. When the temperature of a factory building with a very long longitudinal direction changes, the extent of expansion and contraction of the longitudinal members is large, which causes the deformation of the entire structure, generates a large temperature stress in the members, and may lead to the damage of the wall and roof. In order to avoid such adverse consequences, transverse temperature expansion joints are often used to divide the single-storey steel structure factory building into temperature sections that do not affect each other during expansion and contraction.

Design and technical performance of migrating modern steel structure buildings

The key to the success of the design of the steel structure building design is the technical conception and performance. In the deepening of the scheme design, it is necessary to cooperate closely with the structural engineer, the equipment engineer, and even the mechanical engineer. At this time, technical performance is a natural thing. Whether it is spatial form, formal volume or structural nodes, it is very important to influence its architectural design and performance. The following will illustrate this point from several aspects. (A) Technical performance of steel structure architectural design The conception of architectural image is a creative process of conceptual image, which is one of the difficulties in architectural creation and one of the core issues that have received much attention in architectural design. Looking back at the development of the relationship between architecture and science and technology since the Industrial Revolution, we can clearly find the hysteresis of architecture's response to technological change, which reflects the deep status of architecture in social culture and the relationship between architecture and people's way of life. close relationship. In addition, the emerging information revolution in modern times is widely permeating and involving every field of social activities, so that modern scientific thinking is integrated into architectural design, and great changes have taken place in the planning, architectural and landscape design methods of new projects. The purpose of architectural design has also developed from the pure pursuit of beauty to the pursuit of reasonable solutions to problems, which has fundamentally changed people's previous understanding and design methods of architecture, and finally affected the traditional architectural views formed by human beings for thousands of years, such as high Jipai architecture is its main representative, which embodies superb skills with exquisite nodes and fine processing, and designs and "manufactures" buildings with a higher level of craftsmanship. (B) The detailed design of steel structure buildings has higher requirements. The higher the complexity and refinement requirements of steel structure building design, the higher the requirements for detailed design. Because detailing determines whether a place is finally confirmed and its quality. In modern steel structure buildings, various metal structural rods and the details of the nodes connecting the metal rods are often exposed, giving the building a strong sense of technology, such as the Pompidou Art and Culture Center in Paris, France, built in 1977. , its steel columns, steel beams, trusses and other structural components are exposed, which not only reflects the beauty of technology, but also reflects the wisdom and ability of people. Therefore, it is very important for steel structure buildings to maintain high design requirements for detail quality, and special attention should be paid to steel structure buildings. (C) Architectural planning is also an influencing factor for the design and performance of steel structure buildings. Because steel structure building design has the general attributes of architectural design, architects do not design at will, and the owner's design task book affects the architect's plane and design concept. The effect is significant. Clients expect better performance from designers, and they expect designers and market experts to be more productively involved in the decision-making process of their final product. At this stage, the construction project emphasizes the overall design and the coordination between professional designers, market experts and developers. The design process includes continuous exchange and integration of information and knowledge. In addition, the specialization of steel structure buildings can not only provide a wealth of design knowledge, but also effectively integrate design resources and market experts to be jointly responsible for the building, so that the design and the owner's business intentions can be effectively combined to make the project profitable and reduce risks. Architectural characteristics of modern steel structures (1) High degree of pre-engineering, reduced construction costs, and shortened construction period It has certain versatility and interchangeability with building components of different manufacturing methods. At the same time, the pre-engineering of steel structure buildings integrates material processing and installation, which greatly reduces the construction cost; and accelerates the construction speed, so that the construction period can be shortened by more than 40%, thereby speeding up the capital turnover speed of real estate developers and making the construction energy efficient. put into use earlier. 　　 (2) Steel structure buildings can meet the requirements of super height and super span. The steel structure is uniform, close to the isotropic homogeneou
