Steel structure: "green house" leading the transformation of the construction industry

        In the exhibition area of "China Tomorrow's Home 2022 · Prefabricated Building Integrated Residential Demonstration House", we can see that the steel structure housing components are factory-produced in accordance with the standardization requirements, and the prefabricated construction is adopted to build the industrialized model house on site."Steel structures are energy-saving, land-saving, efficient and convenient, which not only improves economic benefits, but also improves building safety, and greatly surpasses traditional concrete buildings in earthquake resistance."On-site experts said.

"Steel structure is the best annotation for the industrialization of green buildings." SAFS Steel Structure Co., Ltd., an exhibitor of the Housing Expo, said that green buildings represented by steel structures are the vanguard of the transformation and upgrading of the construction industry.

The modernization process of my country's green building industry is accelerating. Relying on industrialization pilots to promote eco-friendly, high-quality, affordable and comfortable steel structure buildings is becoming the main theme of new residential buildings in the future. "Steel structure building subverts the manufacturing process and construction process of traditional buildings. It is the core content of the future green building industrialization and an important symbol of industrial modernization."

In fact, steel structure buildings not only promote the upgrading of the construction industry, but also provide a solution for steel enterprises facing transformation problems. High energy consumption, high emissions, and high pollution have always been a problem for domestic steel companies, and serious excess production capacity directly affects the survival of the company. Can we walk on two legs to make the industry "green" and develop an industry that does not contradict ecological and environmental protection; and let the "green" become an industry and develop green building industries such as steel structures?

The steel structure is the "green house" connecting the construction industry and the steel industry to transform and upgrade together.

As the main representative of green buildings, steel structure buildings have the advantage of steel recycling rate as high as 90%. Once they can be built in large quantities, steel structure buildings will become "steel storage warehouses". At the same time, steel companies can also ride on the green energy-saving ride. It is estimated that if the industrialized steel structure building production method is popularized in my country, the construction waste will be reduced by about 83%, and the building energy saving will reach more than 50%.

As a green building, steel structure runs through the circular economy development principle of "reduction, reuse, resource utilization, and reduction priority" throughout its life cycle, which can maximize resource conservation, protect the environment, and reduce pollution. This coincides with the goal of "improving the application efficiency of steel products and promoting the reduction and greening of the entire life cycle of steel products" proposed by the steel industry.

At present, my country's steel structure has been widely used in super high-rise, large-span space structure, industrial workshop and other fields, and the application in residential and urban construction has broad room for improvement.

At the exhibition, SAFS Steel Structure's "steel tube bundle combined shear wall structure residential system" attracted the attention of many participants. The system combines the advantages of steel structure building industrialization with the flexibility of concrete building shear walls, and has the characteristics of fire prevention, heat insulation, and integration of decoration. "Not only can several floors be used as a construction section, but also the construction site can be kept clean and orderly while speeding up the construction progress. From an economic point of view, it saves nearly 20% of the cost compared with the prefabricated concrete structure." Tianjin University Evaluation of professors of the School of Architecture and Engineering.

It can be expected that in the future, more "parts" such as wall panels, stairs, etc. will be transported to the construction site instead of scattered steel bars, concrete, and thermal insulation boards;Workers assemble these "parts" into houses with the cooperation of machinery...

With the strong support of the state, the green building industry has gradually achieved a transformation from nothing to something, from weak to strong. Since the implementation of the new version of "Green Building Standard Evaluation" this year, my country's green buildings have shown a strong growth momentum. According to statistics, in the first half of the year, a total of 3,194 green building evaluation and labeling projects were evaluated across the country, doubling the number from last year, with a total construction area of 360 million square meters. At present, among the 287 cities above the prefecture level, 280 cities have proposed low-carbon eco-city construction goals. It is expected that the proportion of urban green buildings in new buildings will increase from 2% in 2020 to 20% this year.
