Environmental protection and energy saving design in steel structure buildings

With the worsening world pollution, people pay more and more attention to environmental protection, forming the concept of green architectural design. The steel structure as an environmentally friendly material has an important role in alleviating the pollution caused by the building. To improve, the level of the steel industry has also developed significantly. The steel needs can meet the construction of the building, and can actually be used in urban construction.

1 Advantages of steel structure architecture

1.1 Steel structure reduces environmental pollution

With the development of the times, the requirements for building materials are getting higher and higher. The original building materials, such as lime, cement, stone bricks, etc. During use, it will inevitably produce a large amount of dust and related building waste. It will only cause environmental pollution and threaten the health of the workers. Each year, some workers will be ill because of the construction site all year round, affecting their health. For a generation, steel can also be recycled, which has a small impact on environmental pollution. It can minimize the production of waste, realize the recycling of building materials, and is conducive to the sustainable development of resources. Steel materials are mainly composed of chemical substances such as carbon steel and synthetic steel. They have less impact on the environment, the production process is short, the production is simple, the amount of exhaust gas has less, and the loss of loss resources is less. The environmental impact is small and suitable for large-scale promotion.

1.2 Energy-saving design of steel structure

First of all, steel is flexible and diverse in design. You can cut steel according to the design. From actual life, increase the area of indoor use, reduce economic loss, meet the personalized needs of design, minimize energy consumption, and reduce waste of resources to waste resources to the greatest extent At the same time, steel structure buildings can realize industrial design, reduce the construction period of construction, thereby reducing the loss of human and financial resources, and achieving energy -saving design. Secondly, the steel structure is highly reliable, has excellent seismic and stretching, and can effectively resist the threat of natural disasters to people’s health. In summary, in contemporary architectural activities, steel structure buildings have the characteristics of energy conservation and environmental protection, in line with the basic national policy of my country’s environment, and the general trend of the development of the times. Therefore, steel structure buildings have been vigorously promoted in life.

2 The problem facing steel structure construction

2.1 Poor corrosion resistance of steel structure

In actual construction activities, buildings inevitably to blow the sun and suffer from wind and rain, and this scene is obviously not suitable for the use of steel structure buildings. Steel corrosion resistance is poor. In the long-term open-air environment, it is easy to cause the decay of steel This leads to a decrease in the bearing capacity of steel, affecting the service life of steel structure buildings, and causing unnecessary economic losses. This requires special treatment of steel. The surface layer is not suitable for steel materials.

2.2 Steel structure, heat resistance, and refractory

As a high -quality energy -saving material, steel structure plays an important role in protecting the environment and saving energy. However, the disadvantages of the existence of steel structures also limited the development of steel structure houses. At normal temperatures, the steel structure is good and the structure is high, but at high temperatures, especially when the temperature exceeds 150 ° C, the nature of the steel is very easy to change. There are different degrees of decline, and as the temperature continues to rise, it continues to decline. Therefore, when a fire occurs, the steel structure building is very easy to collapse at high temperatures. Surgery, so we must apply a fire layer in steel structure buildings, and do a good job of fire prevention facilities and fire drills. At the same time, construction costs will also be increased. And in a normal temperature environment, it is still a fairly high -quality energy -saving material.

2.3 Insufficient understanding of steel structure buildings

Steel structure buildings are the products of the development of the times. Although steel structure buildings have certain advantages compared with traditional buildings, users and developers have insufficient understanding of steel structure buildings, resulting in the development of steel structure buildings into bottlenecks. First of all, in the traditional concept, the value of steel is always considered, so that the construction cost of steel structure housing is high, resulting in higher pre-sale costs, making more people choose concrete buildings. The energy-saving and environmental protection system of steel structure buildings is known as “one of the green buildings”. Steel structure buildings are widely used in modern buildings, mainly using steel as building raw materials, abandoning traditional lime, cement, and concrete materials. It is often used in large span large spans. In the building height of the floor, energy saving and environmentally friendly than traditional building materials, steel structure housing has also become a recognized green environmental protection house, which plays an important role in protecting the environment. Essence Based on this, the environmental protection and energy saving design in steel structure buildings is discussed in detail for reference for relevant persons. Secondly, some people believe that steel structure buildings have high requirements for technology, equipment, and other aspects. On the contrary, steel structure buildings are simple and convenient for design and construction. Low. Finally, the most important, the lack of related technical talents. Under the guidance of the wrong concept, most of the workers recruited lack actual construction experience, the technical threshold is not high, and the necessary professional skills are lacking. , Insufficient technical understanding, lacking understanding of its importance, and. The importance of can invest in steel structure construction activities with the greatest passion. The development of steel structure buildings has a lot to do with the backwardness of the concept of the people. Therefore, this requires the improvement and progress of the concept of the entire construction industry, fundamentally changing the traditional concept from the fundamental perspective. At the same time, it is necessary to increase publicity and increase People’s understanding of the steel structure building.

3 Environmental and energy-saving design of steel structure buildings

3.1 Use thermal blocking technology

The steel structure building plays an important role in energy conservation and environmental protection, mainly because of the introduction of heat blocking technology, reasonable distribution of thermal energy, and the main principle of thermal blocking technology is to cut off or prevent the transmission of the heat energy to the steel so that the temperature of the steel does not exceed the critical temperature. It can overcome the shortcomings of steel heat resistance and refractory, block the heat, avoid fire, and achieve the purpose of protecting steel. At the same time, it has achieved energy conservation and emission reduction in dermatology. The utilization rate of thermal energy is maximized. Thermal blocking technology is widely used in steel structure buildings. For example, setting small holes on steel structures, emission heat, research shows that this method has excellent energy saving and emission reduction effects, or setting insulation materials on the surface of the steel, has possession of the steel surface, and has some. Metal pieces block the function, after the thermal energy and metal slices are absorbed by thermal energy, the thermal energy of reaching the steel will greatly reduce it, and it will have an excellent insulation effect. Strict requirements must have excellent insulation and resistance functions. Both methods use the principle of thermal blocking. While protecting the steel structure, the heat energy is reasonably distributed to play a role in energy saving.

3.2 Preventive pollution design

In traditional structural buildings, due to the use of traditional concrete, lime, and other materials, or a structural angle problem, the sound insulation effect of the building structure is not good, which will cause noise pollution, and the steel structure building will effectively solve the problem of noise pollution. During the construction of steel structure buildings, due to the particularity of steel, the sound will be greatly weakened during the sound transmission process, and the special construction angle of the steel structure building will also greatly weaken the sound. Steel structure buildings will use sound insulation glass on the surface layer. Internal sound insulation materials are also used, so the impact of noise pollution in steel structure buildings is almost minimal. Now, with the development of the times, high -rise buildings are becoming more and more common, accompanied by the increase in floors, followed by the light pollution caused by sunlight on the external wall glass, and the main reason for the occurrence of light pollution is that the internal design of the building is unreasonable. There is no full consideration of the angle between light and exterior glass, which causes great inconvenience to the production and life of residents, and the anti -pollution design of steel structure buildings effectively solves this problem. According to the principle of green building design, steel structure buildings have been designed with steel structure glass curtain walls. Steel structure glass curtain walls use steel to make glass and add optical materials to effectively prevent the direct light of light. Strong seismicity has greatly reduced the weight of the building, and at the same time has a strong environmental protection and energy-saving effect, reducing the generation of urban waste and light pollution. Therefore, steel structure buildings have an important role in protecting the environment, energy conservation and emission reduction, can effectively solve the effects of optical pollution and noise pollution, and realize the integration of steel building materials and modern science and technology, which has promoted the development of environmental protection and energy conservation in my country.

3.3 Use energy-saving materials

During the construction of steel structure construction, due to the simple production and short construction date, the housing form of the steel structure building is flexible and can be designed according to actual needs. Type flooring, etc., light materials and low pollution, have great advantages in promoting energy conservation and environmental protection, minimize building pollution, can also reduce the quality of the building, can achieve effective division of the construction area, expand the use area. Get certain economic benefits. Therefore, the development of the steel structure construction industry can promote the development of my country’s environmental protection and energy conservation undertakings. In the construction process, steel structure buildings are integrated with a number of environmental protection technologies. While promoting the development of science and technology, it has achieved energy conservation and emission reduction.

With the development of my country’s construction industry, my country’s steel output has improved significantly, and the steel structure construction business has also developed to a certain extent. The huge contribution of steel structure buildings in environmental protection and energy conservation and sustainable development is incomparable to the traditional construction industry. Therefore, the state has made vigorous funds and technical support to vigorously develop steel structure buildings. In the future, steel structure buildings and intelligence will be achieved. The integration of new technology products such as Hua has achieved new development of steel structure construction.
