The industrialization of steel structure housing is the only way for the development of China's housing industry, and it will also become a new growth point to promote China's economic development

The steel method is easy to construct, does not damage the original roof, and can prevent the aging of the roof. The temperature difference between the surface of the board after construction and before construction can reach 20 ℃, and the indoor temperature difference can reach 8-10 ℃. The energy consumption of steel structure factories can be reduced by 30% -70%. Ventilation and cooling of steel structure factory buildings: Some machines in the steel structure factory buildings generate heat and water vapor. If these hot gases and water vapor are not discharged in time, they will accumulate in the factory building, causing the temperature of the steel structure factory building to rise and affecting the environment of the steel structure factory building. The solution to these problems is to ensure proper ventilation in the factory and install appropriate ventilation equipment. A reasonable exhaust system will significantly improve the air environment of steel structure factories and significantly reduce the temperature of steel structure factories. 1. Installation of roof non powered ventilator Non powered ventilator is a ventilation device that relies on the principle of air convection for ventilation. When there is a difference in indoor and outdoor air environment, air flow will be generated to eliminate indoor exhaust gas and heat. Its advantage is that it does not require additional electricity and is more environmentally friendly. But it has a strong dependence on the environment and cannot be forced to exhaust. The products mainly include turbine ventilators, strip ventilators (daylighting belt ventilation), ridge ventilators, etc. 2. Installing a roof forced exhaust fan is a ventilation device driven by electricity, which has good exhaust effect and can adapt to ventilation in any environment. Forced cooling of steel structure factory buildings refers to the installation of air coolers on the roof of the factory building. The air coolers use the principle of water cooling to cool the air, and the forced exhaust fans transport the cold air to the indoor machines.

At present, steel structures are an important representative of green buildings. It can effectively handle the dialectical relationship between building energy conservation, land conservation, water conservation, material conservation, and environmental protection, and is a structure with minimal impact on the natural environment in urbanization construction.

The characteristics of steel plate processing are high strength, light weight, good overall rigidity, and strong deformation ability. Therefore, it is particularly suitable for constructing large-span, ultra high, and ultra heavy buildings; The material has good homogeneity and isotropy, and belongs to the ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can be used for specialized production of steel structures with a high degree of mechanization. High strength steel should be studied to greatly improve its yield point strength; In addition, new types of steel sections need to be rolled, such as H-beams (also known as wide flange steel), T-beams, and profiled steel plates, to meet the needs of large-span structures and super high-rise buildings. In addition, there is a non thermal bridge light steel structure system. The building itself is not energy-efficient, and this technology solves the problem of cold and hot bridges in buildings with clever special connectors; The small truss structure allows cables and plumbing pipes to pass through the wall, making construction and decoration convenient. When steel structures are also damaged, we need to immediately detect and solve the problem. Steel Structure Network introduces that the main factors causing steel structure damage are: 1) insufficient structural bearing capacity due to load changes, expired service, and changes in specifications and regulations; 2) Due to various unexpected deformations, twists, disabilities, dents, etc., the cross-section of the component is weakened, the members are warped, and the connections are cracked; 3) Deformation, cracking, and warping of components or connections caused by temperature differences; 4) Corrosion caused by chemical substances and electrochemical corrosion leading to weakened cross-sections of steel structural components; 5) Other issues include errors in design, production, and construction, as well as unauthorized use and operation during service life. There are three main reinforcement techniques for steel structures: 1) section reinforcement method: steel reinforcement is used locally or along the entire length of the component to connect it as a whole and share the force; 2) Change the calculation diagram: add additional supports, adjust load distribution, reduce internal force levels, force displacement of statically indeterminate structural supports, and reduce stress peaks; 3) Pre stressing cable method: using high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness, and stability of the structure..

Inspection methods for steel structure engineering: visual inspection, natural or local water immersion test. 2. The repair of damaged parts of steel (H-shaped steel, C-shaped steel) in the installed steel structure should comply with regulations. Inspection method: Visual inspection. 3. The connection nodes of columns and steel beams should meet the design requirements, and there should be no detachment or broken welding of the seams between the steel and the steel connection parts. There should be no peeling or delamination at the hot fusion bonding points. Inspection method: manual testing. 4. All connectors and fasteners shall meet the design requirements. Inspection method: manual testing. 5. Whether the steel beams have been treated with rust prevention, and if the final quality is still uncertain about the rusting situation in the gutter, you can also seek professional inspection departments for testing.

The popularity of steel structure engineering in the construction market is not only due to its ease of construction and dismantling, but also inseparable from its safety performance. Today, we will take a detailed look at the widespread use of steel structure housing in the world. In the world's super high-rise buildings, pure steel structures account for about 50%, and more than 60% of high-end housing abroad uses steel structures. Due to the fact that steel structure residential buildings in China are currently in the initial stage of development and do not have fully mature complete sets of technologies and products, the following issues should be noted from the road and experience of steel structure residential buildings: Currently, there are no specialized technical specifications for steel structure residential systems in China, and only existing steel structure design regulations, high-rise civil building steel structure design regulations, building fire protection design regulations, residential building design regulations, etc. can be referred to when using them. The technical level and standards vary greatly, and further research and development are needed to design an economically reasonable steel structure system with wide promotional value. Secondly, the market demand for steel structure engineering has not reached the level of industrialization, and the functionality of related products is single. The degree of industrialization is not high enough, and the product quality cannot meet the standard requirements of residential industrialization. Thirdly, the corrosion resistance and fire resistance requirements of building steel are high. Data shows that ordinary steel without any protection will soften within 15-20 minutes once it is subjected to corrosion and fire. The industrialization of steel structure housing is the only way for the development of China's housing industry, and it will also become a new growth point to promote China's economic development. The steel structure residential system is easy to achieve industrial production and standardized production, and the supporting wall materials can use energy-saving and environmentally friendly new materials. It belongs to green and environmentally friendly buildings, renewable and reusable, and conforms to the strategy of sustainable development. Therefore, the research results of the complete technology of steel structure residential system will greatly promote the rapid development of residential industrialization, directly affecting the development level and prospects of China's residential industry. If this trend continues, we believe that there is still a lot of market space waiting to be explored for steel structure engineering. We will continue to improve and optimize it according to the needs of consumers..

We will continue to strive for survival through quality, development through reputation, and create the most satisfactory projects for customers at the most affordable prices.

Steel structure buildings have become commonplace in recent years. Large shopping malls, high-rise buildings, and bridges all use steel structures as the main frame structure, replacing traditional reinforced concrete structures. Therefore, in the process of steel structure construction, the following points should be noted. According to the website of Activity House, the floor slabs of multi height steel structure buildings should have sufficient rigidity to transmit and disperse energy during earthquakes. The floor beams can be steel-concrete composite beams or non composite beams, and the floor slabs can be made of pressed steel and reinforced concrete with a layer of reinforced concrete poured on top to facilitate the construction of steel structure projects. Generally, cast-in-place reinforced concrete floor slabs are less commonly used. Prefabricated reinforced concrete floor slabs have poor stiffness and are not suitable for use in high-rise steel structures. If they must be used, in addition to reliable seismic structural connections between prefabricated slabs and steel beams, a reinforced concrete surface layer with a thickness of not less than 4cm should also be poured on top. Composite steel structures must use shear connectors to connect the two materials, and the connection should be divided into rigid connectors and flexible connectors according to their deformation capacity. When using prefabricated reinforced concrete floor slabs with prestressed thin plates and cast-in-place concrete layers, or general cast-in-place reinforced concrete floor slabs or other lightweight floor slabs, the floor slab and steel beams should be reliably connected to ensure the integrity of the floor slab. Square steel and T-shaped steel are rigid connectors, while cylindrical head bolts, channel steel, and bent steel connectors are flexible connectors. Cylindrical head bolts, channel steel, and bent steel connectors are flexible connectors. The commonly used connectors are cylindrical head bolt shear connectors. For frame composite beams in strong earthquake zones, it is not advisable to install bolts in areas with high plasticity to prevent node damage due to excessive beam stiffness. In strong earthquake zones, the compression effect of columns on the floor slab should be considered when the steel structure floor slab transmits force to the column. If necessary, steel bars and stirrups should be added to the adjacent parts of the steel structure floor slab and column. Or adopt other effective measures to enhance the torsional stiffness of the structure. The above is a list of precautions to be taken during the construction of high-rise steel structures, written for the website souhdf.com. We hope it will be helpful for friends in the construction industry..

China already has the conditions for developing grid steel structure residential buildings, which are energy-saving, environmentally friendly, and land saving. Although grid steel structure residential buildings are receiving increasing attention in China, there is still a significant gap in their promotion compared to developed countries in the world. According to the head of relevant industry associations on the 10th, the proportion of steel structure residential buildings in China is currently less than 5%, while in developed countries it is generally above 40%. More than half of China's steel is used in the construction industry. Last year, the total amount of steel used for construction reached 170 million tons, but the vast majority of it was used in traditional reinforced concrete structures, with only over 10 million tons used for steel residential buildings. The use of new wall materials in grid steel structure residential buildings can improve energy efficiency by 50%, increase effective usable area by 6% to 8%, shorten construction period, save construction water, and conform to the development direction of national industrial policies. It is one of the excellent forms of residential buildings to achieve energy-saving and land saving goals.
