steel structure engineeringHelp the solid building expoThe expo in the lot of the venues are wonderful clips

steel structure engineeringHelp the solid building expoThe expo in the lot of the venues are wonderful clips. And the most impressive, is broad pavilion screening venues of live video.

Short film tells the broad pavilion in sight - a day to complete construction crane to lift the floor of the large, steel beam, a layer of laid in place, workers skilled up screw down the screws, in their heads at the same time began laying a new floor, Windows, walls, etc is done in the same way.

Movie ended, the audience gave the story of the thunder of applause construction speed of movies: complete build 6 floors in 24 hours, this is a miracle in the history of architecture. FuGuangXu said the big news center, the live video is in the expo garden high-rise residential area on the top floor, piece is compared with the clips and the effect after the fast forward.

Distance, broad pavilion by a white L and a pyramid building together and become, appearance is concise and simple. In the visual effect of the expo site, and without a sense of jing is colourful. But it is the simple venues, it is the cleanest air in the expo garden, aseismic rank highest venues.

Housing security is the key of the architecture design

Is located in puxi side of the great hall building itself is a exhibits. This 6 f has a new name can be built, the meaning of sustainable architecture.

Concrete manifestation is realized in the process of building the factory operation, mass production in the factory construction, minimize the site construction. The advantage is can save a lot of time, reduce the generation of construction waste. At the same time, the structural safety of building component can test again and again, until 9 degree seismic standards.

More than 200 years ago, the British invented the cement. From then on, the city with tall buildings. Support concrete and brick structure, is the construction of column and beam. Big construction project, it is the column, beam and singled out the keel structure, made of Steel structure warehouse. On the metope adornment on the basis of the steel structure.

This in only one day of completing 6 layer of steel structure building, because of its unique seismic design, through the national jianke institute earthquake research institute of 9 degree seismic testing, reached the highest current global seismic grade.

House in the future, no matter how novel and unique appearance of ideas, no matter how many new technologies, new materials, using safety of building structure is the most important. Great pavilion located near the earthquake house sustainable architecture gives people hope.

Unique brace can magnitude 9 earthquake resistant design

The seismic behavior of the wall, in order to guarantee sustainable architecture used in the original brace structure. The diagonal bracing is adopted in the construction Steel structure warehouse supporting force, and between the column and measure lines into the stability triangle.

Broad pavilion earthquake science and technology is the core principle, namely: brace + lightweight + factory. According to introducing, the destructive force of the earthquake is mainly horizontal thrust, pillars again strong also carry the horizontal thrust, the aseismatic capability can therefore be built.

First, is to rely on in the brace around the buildings and at regular intervals in the middle of the diagonal brace. Second, it is light weight. Strong earthquake damage = because x building self-respect, the greater the weight of the more destructive power. Broad pavilion using seismic average thickness of 30 mm of concrete floor, and traditional building about 100 to 200 mm. 50 layers can be built under the dead weight, if you include all materials and equipment, use of aseismic building 6 times lighter than traditional architecture of the floor above.

Third, it is factory. Earthquake-resistant buildings ceiling and the upper floor is close 2 for one, is a standard size, together with the concrete floor were completed in the factory, factory rate of 99%, and the construction waste is only 1%, can be assembled at the scene construction, not far-fetched and redundant, that is the core of the factory.

According to information, broad pavilion can fight the high intensity earthquake, from the building has a great magic weapon original three seismic, namely "brace, lightweight and factory. Museum no ordinary brick, with one floor on the top floor, the ceiling is 11.9 meters long, 3.9 meters wide, 3.9 meters thick, the unified specification, complete precast in factory assembly line.

Also because of this, all the materials enter the expo garden, not only created the miracle of construction completed in one day, and together the "9 degree seismic 5 times 6 times, material saving, energy saving, 1% of construction waste, 1% factory", become a has a strong technology based on sustainable architecture.

Enclosed buildings ventilation design about people's health

Make air conditioning from the broad group of have the absolute right to speak in terms of air purification. The world expo in the great hall of the ventilation design is very characteristic. The whole venue no air conditioning, but there are several air vents on the ground.

, new fan heat recovery ventilation exhaust quantity of cold (hot) for air cooling (heating). These vents have two functions: one is to adjust indoor temperature, the second is the indoor air circulation and outdoor air purification after discharge to indoor, so as to achieve the purpose of the clean air.

Great hall walls, the roof adopts 170 mm polymerization foaming insulation material; Windows USES the three layers glass plastic casing window, and is equipped with automatic window and the window shade heat insulation; Walls, Windows, ventilation, three aspects of "zero tolerance" heat insulation measures, make the building even without central heating in the winter nor too cold, summer air conditioning only to the human body, lighting and electrical heating, energy consumption is equivalent to only about 20% of the traditional architecture.

At the same time, it was a "breathing" ultra clean architecture. Indoor and ventilated good, thorough of 3 times, air changes per hour is more than twice as many as 5 star hotel also. In particular, due to the electrostatic precipitator were used of new turbines, outdoor air through the machine when indoors, 99.9% of the dust and bacteria will be filtered out.

A set of data can illustrate this: in the great venues, a liter of the dust in the air could be purified to about 1800, while outdoor dust in the air for as many as 300000.

At the end of the world expo 2010 Shanghai, most of the venues to dismantle. While broad pavilion removed intact, and reconstruction in other cities, this also is the perfect interpretation of "low-carbon expo".

At the same time, the great hall of the seismic exploration and seismic experience are warning people, prevent response to the earthquake disaster, we still have a lot to do.

Sixty years to the development of China's Light steel structure

Sixty years to the development of China's Light steel structure including building steel structure, bridge, tower mast, containers and hydraulic structure in various fields. Now is only house steel structure describes the development of 60 years.

Sheng in the early stage (50 ~ 60 s last century)

New China in 1949, the newly established his devastated when steel output is very low, only 1.35 million tons per year (now more than 500 million tons). Steel structure construction only rely on the Soviet economic and technical assistance, the Soviet union built 156 heavy industrial plants, including metallurgy, heavy machinery, aircraft, automotive and other industrial, such as anshan steel, wuhan steel, dalian shipyard, Harbin aircraft manufacturing plant and so on. In a short span of few years, a lot of steel structure construction industry workshop(steel column, steel roof truss and the crane beam), trained a large number of talents in design, manufacture, installation, to lay a solid foundation for future development.

Low water stage (the 70 s and 1960 s)

This period requirements increases the state departments of steel structure, steel production was still not much, only 20 million tons per year, countries put forward the policy of saving steel, some one-sided understanding of no steel structure at the time, so fewer steel structure. From the country as a whole, also built a few large steel structure engineering. Due to save policies, steel plate rack project is widely used, especially successful research welded hollow spherical node, small and medium span across the country are welding ball node plate rack abound, meanwhile bolt ball node network frame are also introduced.

Stage of development (in the 80 s ~ 80 s)

This 20 years should be a prosperous period of the development of the steel structure, due to the steel structure have some unique advantages, has become the main structure in construction project, especially the rising steel production, in 1997 1997 tons, to the development of our steel structure created there is a condition. In 1998 our country has been able to produce rolling h-beam, steel structure provides a new steel series, the steel structure engineering development mainly has the following several aspects.

& ndash; & ndash; Single layerworkshopFrame structure. The larger steel, seamless steel pipe, thermal power plant, etc. Its characteristic has a large area (200000 square miles), column height (50 meters), column spacing (48 meters), even across multiple across (8), large crane lifting weight (450 tons), etc.

& ndash; & ndash; The spatial structure. Flat space truss has been widely used large stadium, exhibition center, shopping mall, airport, station, warehouse, factory, etc. In particular, most of the 1990 Asian games venues have adopted welded hollow spherical nodes flat rack. Libraries in the capital Beijing, 1996 (153 m + 153 m and 90 m deep), four pyramid three layer network frame welding ball node. That same year 150 hangar taeco & times; 70 MiJianCheng, using unbonded manual sola lever arch at the gate.

& ndash; & ndash; Net shell of several projects. In 1994, tianjin gymnasium (D = 1994 m) double-layer spherical reticulated shell; Changchun stadium in 1997 (191.8 m) 146 meters & times; heilongjiang HuaBingGuan double square steel pipe network shell, 1995 (86.2 m & times; 191.2 m) on both ends of the central cylinder reticulated shell hemisphere shell. 1995 sichuan panzhihua gymnasium adopt eight side petal type double-deck net nanning, span of 60 meters, several times with prestress. This is the first time at home several times with prestressed concrete engineering. Was built in 1998 the Shanghai international gymnastic center the main hall, adopt aluminum alloy spherical reticulated shell, 68 meters in diameter. Network frame and net shell has a corresponding design procedures.

& ndash; & ndash; Cable structure. The structure development is slow, only a handful of engineering use, such as shandong zibo stadium (54 meters), anhui stadium (53 m & times; 72 m), wuxi stadium (43 meters) 40 meters & times; and jilin BingQiuGuan adopting different cable network system.

& ndash; & ndash; Space structure and the arch and rigid frame combined system is composed of concrete development such as the Asian games in Beijing shijingshan gymnasium (triangle, the length 99.7 meters), etc., is a hybrid structural system.

& ndash; & ndash; Membrane and the membrane structure. Get certain development since the late 90 s, is still in the continually expanding role, is very promising. Such as built in Shanghai in 1998 and 1998 stadium grandstand is the relatively large size of cable membrane structures.

& ndash; & ndash; High-rise building steel structure. High-rise building steel structure started relatively late, in 1987 the first 165 meters of shenzhen development center mansion, later the jingguang center 208 meters, 325 meters in shenzhen diwang building, 1996, 1999, Shanghai jin MAO tower 420 meters; In recent years, built in the Shanghai world financial center.

& ndash; & ndash; Light steel structure. Light steel structure is developing very fast, especially the door frame, such as industrial factory buildings, warehouses, cold storage, greenhouse, hotels, villas and so on to get a large number of applications. Light steel structure housing also began to research and experimental project, is very promising. This period steel structure specification and revised in 74, to 88 specification.

Strong period (s) 2009 years ago

Nearly 10 years of rapid development of the steel structure project of that range is wide, is unprecedented, is the major country of steel structure. Steel output was 400 million tons in 2006, the highest in the world, this also for our developmentsteel structure engineeringHave created favorable conditions.

Traditional space structure such as grids, continue to be heavily promoted net shell, etc. New space structure began to widely used, such as Zhang Xianliang, chord truss string and dome, etc. Shanghai pudong airport, Harbin exhibition center, Shanghai exhibition center, guangdong exhibition center, etc are more than 100 m copies string truss, it is also rare in the world. Especially space structure is adopted for a few games, the expo is more big, such as: the 2008 Olympic Games in Beijing new 37 venues, shandong jinan national games in 2009, the 2010 Shanghai world expo and guangzhou Asian games, the 2011 shenzhen universiade. Be worth what carry is the 2008 Olympic Games in Beijing 12 new venues, it represents the skill level of the steel structure in our country. National stadium (bird's nest) (& times; 292 meters 292 meters, consists of a series of door frame along the inner ring of the large span of space structure, the steel consumption of 42000 tons; national swimming center (water cube) (170 m & times; 70 m & times; 29 meters, special-shaped polyhedron grid structure); the national stadium, 144.5 meters (114 meters & times; bidirectional zhang chord truss structure); laoshan bicycle pavilion (133 m double layer spherical reticulated shell), wukesong gymnasium (120 meters 120 meters & times; two-way orthogonal is put truss composed of rack); Beijing industrial university gymnasium (badminton gymnasium (105 m chord dome); China agricultural university gymnasium (wrestling) (90 meters 90 meters & times; the door frame structure); Beijing university gymnasium (table tennis) 64 meters (64 meters & times; by 32 common radiation of truss string net shell) and other projects.

Shandong jinan 2009 national games main stadium, gymnasium, swimming pool and tennis center, the whole buildings adopt & other; Throughout east Netherlands XiLiu &; Building modelling, reflect the local characteristics of jinan, specifically have a stadium with 122 meters in diameter chord dome, will become the biggest span in the country and even the world chord dome structure.

The Shanghai world expo venue is spectacular. Which one axis and four pavilions (China pavilion, the expo center, theme pavilions, performing arts center) permanent buildings are very distinctive. Hundreds of other represent different creative national pavilion, enterprise pavilion building is also very worth visiting.

Except a few games and the expo venues, of course, there are worth questioning: Shanghai world financial center, the new terminal building of Beijing capital international airport, Beijing south railway station, national centre for the performing arts, China central television (CCTV) new sites, Shanghai south railway station, Beijing new poly plaza, zhengzhou international conference and exhibition center and nantong stadium, guangzhou TV tower, west tower, a new theatre, museums, etc. Engineering due to these characteristics, it also produced many new technology in steel structure manufacture and installation. Also emerged a large number of advanced steel structure enterprise at the same time, the steel structure industry for the future development is very favorable.

About steel structure residence, during this period due to policy support, engineering technical personnel's efforts, has made great achievements, the construction of the pilot project, the publication of technical specification has been carried out, have the right conditions for further development. Steel structure specification in 1988 and was replaced by 2003 specification, this year 2003 steel specification is revised, updated version of the standard one, two years can be realized.

The steel structure development vision in the future

The above description can be expected steel structure development vision in the future. & other; 11th five-year plan & throughout; During planning, the ministry of railways plans to build 548 station in one hundred, steel structure, civil aviation administration to invest heavily in plans to build 175 large airport terminal, all over the country provinces and cities also have vigorously construction of sports venues and conference and exhibition center planning. Now is approaching & other; The 12th five-year & throughout; The start of the implementation of, I believe that the further development of the steel structure of the development of our country will be more.

structural steel beams housing: need policy support

Steel structure housing: need policy supportThe 2011-6-10 10:43:28 signature: this version on April 14, 2011 published and who Steel structure: the sustainable development of the housing industry and strong spine throughout Penny, cause widely discussed in the industry. How to promote China's large structural steel beams Over the years, to become the industry experts and structural steel beams Research and development department common concern. In this paper, such as a large number of development to the steel structure housing, need a series of policy support, I hope that this view can be promote the rapid development of the steel structure housing a good recipe.
Steel structure housing in more than ten years of development process, met many problems. Whether steel structure manufacture enterprise or real estate development enterprise, do not have the steel structure housing as the main force of the housing market. In fact, the steel structure housing is the most can realize residential industrialization of a residential building way, it's not a lot of promotion, the fundamental problem is the lack of related policy support. In addition, the related departments and no will and who People-oriented and throughout Implement the concept of our housing market.
Deepening the policy guidance to strengthen industry legislation
In China, to vigorously promote the steel structure housing, first of all, shall establish unified organization, set up system promotion plan.
Secondly, in the legislation, the relevant departments to formulate relevant laws and regulations to promote the development of the steel structure housing, such as who and The steel structure housing industry resource construction planning & throughout For the steel structure housing industrialization of land resource, energy saving, environmental protection and development provides a legal basis, and who Steel structure housing industrialization base construction method and throughout In promoting the healthy development of the steel structure housing industrialization a demonstration effect. Clear the central government and local government in the steel structure housing supply responsibility, formulate plaintext law that local governments often should pay attention to the jurisdiction of the residential areas of the subordinate status. Make steel structure housing industry system technology development subsidy system, such as research and development to the steel structure housing enterprise provide a certain amount of research funding assistance, and who Steel structure housing industrialization funds and throughout For the steel structure housing industrialization to promote rapid development to provide financial support, the government should support the small and medium-sized enterprise in this research.
Finally, establish and make effective steel structure housing industrialization, financial support policy. Establish and who Steel structure housing industrialization special fund and throughout , reduce the low-income housing loan interest, take fund institution "one-stop" work style, integration and economic means. The use of fiscal and financial means, create the steel structure housing industry fund mode, to the steel structure housing manufacturing enterprise and ordinary residents provide long-term low-interest loans, all citizens to buy steel structure housing in the standards prescribed by the state, all within to and who Steel structure housing industrialization special fund and throughout Apply for low-interest loans. Through a series of fiscal and monetary system's implementation, the correct guidance enterprise, make its research direction and the policy of the government guide phase with established steel structure housing technology policy implementation. The government subsidies and financing system is the national guidance and management of the construction of the steel structure housing industry is an important way, not only can apply for the individual, the local government also can be in residential construction funds shortage and who apply for Steel structure housing industrialization special fund and throughout And the steel structure housing private enterprise can also through to and who Steel structure housing industrialization special fund and throughout Apply for long-term low-interest loans. For some certain types of steel structure housing, such as aging residential, energy-saving residences, still can apply for special financial subsidies or low-interest loans.
Complete set product to establish the relevant specification
Steel structure housing in the process of development meet the most prominent problem is supporting problems, such as wall material research work, the purpose is to meet the production requirements of the wall products; Promote economy applicable, construction simple floor, the purpose is to reduce the cost of the steel structure housing; To strengthen the scientific research work of nodes, the purpose is to reduce the welding work in construction can, simple installation, so as to save the time.
At present, in China to develop the steel structure housing, it is urgent to establish a wide range of this agreement. We can from the establishment of the relevant specification, the steel structure housing industrialization and standardization direction to advance. In the industrialized housing era, it is important to the factory and production line. In the unified standards and specifications, under the guidance of establishment conforms to the market demand of steel structure housing system, in order to meet the housing market multiple needs. With the guidance of standardization, the establishment of the construction and quality management system, improve the steel structure housing construction efficiency, reduce the cost, the advantages of steel structure residence truly play out. Therefore, it is urgent to research the independent innovation of intellectual property rights technology and formulation and industry adapt to the standard and norm system.
In addition, attention should also be paid to the steel structure housing interdisciplinary education and training of technical personnel. The environmental protection consciousness of the architect, artistic accomplishment, social responsibility and the steel structure processing, manufacturing, installation process of familiar degree, directly affect the whole process of the steel structure housing construction. Improve the quality of the professional team, to ensure that the steel structure housing performance, quality and improve the efficiency of building lay a good foundation.
For industrialization ground strengthening base construction
To speed up the steel structure housing industrialization base construction, and the construction is to solve the sustainable development of the society and effective ways and the best solution. Steel structure housing industrialization base should have the functions: one is the research and design of the steel structure housing integrated system and a complete system of the part; Two is the study of the steel structure part, pressure type steel plate and wall materials processing and installation; Three is the research and the steel structure housing of supporting the inside and outside the walls and floor system; Four is to develop and who Steel structure housing industry general modulus standard & throughout , through the module standard realize accessories generalization to ensure that different manufacturer member of generality, Five is to develop and who Steel structure housing product design catalogue and throughout As the center to promote universal system development; Six is the general part called & who Steel structure housing department product catalogue and throughout , each manufacturer can be listed in their products and who Steel structure housing department product catalogue and throughout , designers can arbitrarily choose general list of product design; Seven is the steel structure housing modular coordination, narrow finalize the design unit, standardization and diversification better unify, the steel structure housing industry building part of standard gradually into the standard. Proof of foreign experience, to change the backwardness of the residential construction, it is necessary to promote housing industrialization, go high scientific and technological content, good economic returns, low resources consumption, little environmental pollution, human resources can be fully used the new industrialization road.
The so-called housing industrialization, is through the way of industrialization production house, construction of high efficiency, low cost. To be specific, housing industrialization is the housing market demand as the guide, building materials, light industry, etc, supported by factory producing all kinds of residential components and finished products, semi-finished products and field assembly, and the talents of science and technology as the means, through the whole process of housing production design and components production, construction, sales and after-sale link connection for a complete industrial system, so as to realize the housing production, supply, sales integration of the production and business operation organization form. Accelerating housing industrialization, is not only guarantee the quality of residential and improve labor productivity, and the need to save resources and reduce the cost of the need, but also shorten the construction period and improve labor condition needs.
In our country promote housing industrialization, one is to establish promote the industrialized housing mechanism; The second is to develop and promote all kinds of advanced technology, Three is to cultivate and support backbone enterprise: four is to use demonstration project guide; The fifth is to make effective technical and economic policy.
In addition, the need to further speed up the steel structure housing industrialization base construction, broaden and who Steel structure green energy-saving residential building system and throughout Technology in the application of real estate development, creating and who The green building, science and technology, real estate and throughout To promote our country housing industrialization process, in order to promote the recycling economy and building a harmonious society contribution strength.

steel construction can't ignore the use of fire retardant coating

steel construction  can't ignore the use of fire retardant coating Although now a lot of buildings will use steel structure framework for building. But because of the special steel material performance, a lot of time need to pay attention to the anticorrosion properties. So fire coatings used insteel structure engineeringIn the middle, is a necessary process.
Fire coating for steel structure building put on and who Protective clothing and throughout
Steel structure building with rapid economic development, China construction steel structure since the 1990 s to get more and more widely accepted and used. modernsteel structure engineeringChina is the important content of large-scale modern buildings. Due to the steel structure has its light dead weight, basic low cost, suitable for soft foundation and easy to install, construction fast, the construction period is short, less pollution, good resistance to shock, and other comprehensive advantages, so steel structure building by the ministry of construction as promotion project. But in recent years, steel structure building fire accident frequency, the CCTV new site fire event for people again was a wake-up call.
China construction metal structure association XueFa senior experts believe that steel structure building fire prevention is always the focus industry experts, China's steel structure building fire protection technology has advanced foreign, at present widely used method is: putSteel structure fireaint coating in steel component surface, with a view to play a fire insulation protection, prevent the steel products in the fire temperature quickly and reduce intensity, avoid steel structure lose support ability and lead to building collapse. At present,Steel structure fireaint the research, production and application of more and more be taken seriously.
As we have learned, our country fireproof paint production enterprise after twenty years of development has begun to take shape, the production enterprise development to 250 above, but in many of the fireproof paint production enterprise, enterprise scale, management level and technical level is uneven, the high quality product rarely. In many production enterprises, only more than half of the enterprise through the ISO9000 quality system certification. The survey found that the domestic market sales of fireproof paint products are common problems: fire performance low, easy to fall off, decorative poor, poor durability and quality is not stable.
At present, the domestic steel structure building more, in order to achieve fire requirements, the owner may not have the imported steel structure fire retardant paint, using imported fireproof paint though can achieve fire requirements, but nearly 70000 yuan 1 tons of cost price let builders pain in the neck. For fireproof paint is concerned, the key lies in the reasonable formula and production process.
Construction steel structure corrosion nots allow to ignore
After years of development, at present, the steel structure building industry vigorous development, however, the relevant laws and regulations, standards and the promulgation of the relative lag, in recent years in the steel structure building and many problems in, such as the 1998 in zhejiang happen tens of thousands of square meters of light steel plant and individual network engineering collapse accident; Somewhere a span of 70 meters of space truss structure engineering, after five years use suddenly overall collapse. The accident in addition to design, production, installation problems outside, steel structure corrosion is a very serious problem.
XueFa said,steel structure engineeringThe owners, users, design and construction of the enterprise on the steel structure of the protection problems are the lack of enough attention, in consciousness still stay in the traditional anti-corrosion technology. Due to the material and construction technology choice improper, often causing premature steel structure corrosion or damage. At present, whether project owners, users or constructor for construction how to detect the performance of anticorrosive coating, basic downplay. In addition, some engineering owner completely according to graph and decide, in the project before start, did not find special anticorrosive engineering experts to evaluate the whole engineering anticorrosion scheme, no delegate professional anti-corrosion construction engineer or experts to anticorrosive coating for strict inspection, all to the project supervision. Project supervision on corrosion resistance of comprehension is also according to graph and decide, project delivery after use basic no corrosion maintenance detection, and regardless of the actual conditions of the large cut the cost of the anticorrosion engineering, all of these make steel structure life shortens greatly. Comprehensive of the world to the steel structure building protection practice proof, with heavy anti-corrosion coatings and be carried out anti-corrosive coating with fire anti-corrosion coatings on fire anti-corrosion coating is the most economic and effective, the most simple and practical, the most popular a kind of method.
Construction steel structure to improve the long-term protection technology
XueFa think, the steel structure anticorrosion technology, especially long-term anticorrosion technology is very important. Anticorrosion design life is 30 years, according to the different environment of indoor and outdoor use different anticorrosion coating. In fact coating system is made up of two different structure coating combination and become, include electrochemical protection of zinc rich primer, scaly natural cloud iron mainly intermediate paint, paint a skeletal support function and shielding performance is remarkable. Epoxy paint have good adhesion, abrasion resistance, water resistance, resistance to chemicals, other varieties coating have far more.
At present, the countries all over the world to building fire problem has certain value and introduced the corresponding fire safety requirements. Such as the United States two layer below the lower house refractory limit is 30 minutes. For fire rating requirements, according to different actual situation, each country has its own standard. Will China's actual situation, combined with the overseas experience, XueFa advice, because the Chinese property concept is stronger, in the fire, people not only to escape, and fire, rescue property, this would be a waste of time. So to make the residence with steel structure specification cannot copy foreign standards, and combined with the actual conditions in China work out suitable product standard.
In short, steel structure building to be popular in China, but also need to solve the technology and production process of the many problems, especially in fire anti-corrosion, should further increases the research and development dynamics, steel structure building as soon as possible to solve the problem of fire.
