Building a house is like "building blocks"! The assembly rate of intelligent buildings in Tianjin is as high as 94%

Can you imagine? House construction is like building blocks. All components are prepared in advance and assembled directly on site. At present, the highest building assembly rate has reached 94%. Recently, Tianjin's "Intelligent Construction and New Building Industrialization Technology Exchange Conference" was held in Tianjin. Experts, scholars and construction enterprises in the intelligent construction industry gathered together to provide suggestions for intelligent construction.

"Currently prefabricated buildings have steel structures, reinforced concrete, and a combination of the two. The white-collar apartment in the Ziya Circular Economy Industrial Zone in Jinghai District has realized all the prefabrication from construction to decoration to furniture, and the assembly rate has reached 94%, which is at the leading level in China. " Chen Zhihua, a professor at Tianjin University and vice president of Urban Construction University, said that at present, prefabricated models are being promoted across the country, but there is still a lack of standardization. In the next step, relevant policies should be introduced, standards should be unified, and industrialization and industrialization should be realized through standardization.

Zhang Xizhi, deputy general manager and chief engineer of Tianjin University's General Institute of Architectural Design and Planning, said: "The topic we are studying is a new type of prefab combining steel structure and reinforced concrete. That is, the main body of the building is still reinforced concrete, and the different modules are connected with steel structures, which can solve the winter construction problems. The steel structure is easy to install, but anti-corrosion and fire prevention measures must be taken after installation. "

Daqiuzhuang Sino-German Eco-city under the concept of "double carbon" is located on the south bank of Tuanbo Lake in Jinghai District. As a zero-carbon construction industry base, Sino-German Eco-city vigorously advocates zero-carbon construction. When planning the core area, the proportion of zero-carbon buildings in the area is required to reach 100%, and the development of green buildings is vigorously promoted. At present, the Sino-German Zero-Carbon Exhibition Hall, which was constructed by China Railway 18th Bureau and participated by Lvjian Dadi Construction and Development Co., Ltd., has begun to take shape.

At present, the "new self-locking prefabricated building system" jointly developed by Tianjin University and China Railway Construction Bridge Bureau is about to be put into use in the prefabricated building production base. "Between two prefabricated components, such as wall panels and beams and columns, the 'self-locking' is achieved through the friction of the steel structure's mother-in-law buckle, which completely realizes that building a house is like 'building blocks'. The traditional method is to use concrete grouting after installation, and the construction progress is affected by the weather. We are about to put into use the supporting buildings in the factory area, and choose autumn and winter construction. It is expected that the assembly rate will reach more than 90%.“ said Liu Yang, deputy general manager of China Railway Construction Bridge Engineering Bureau Group Construction Assembly Technology Co., Ltd.

It is understood that at present, the total construction area of prefabricated buildings in Tianjin has reached 14 million square meters, and the entire industrial chain of prefabricated buildings research and development, design, production, construction, and testing has been gradually improved, forming a good trend of comprehensive development.

"At present, the 'Tianjin Modern Construction Industrial Park' located in Jinghai District is the only state-level park-like prefabricated construction industry base in Tianjin, and there are also 7 national-level prefabricated construction industrial bases approved by the city. This year, we recommended to the Ministry of Housing and Urban-Rural Development 5 companies including China Railway Construction and Bridge Bureau to apply for prefabricated construction industry bases. " Hou Xuegang, a second-level inspector of Tianjin Housing and Construction Commission, said that by holding this exchange meeting, we will continue to explore a batch of replicable and popularized prefabricated building development experience and innovative technologies for promotion and application in the city. Through organizing technical exchanges and project observation, we build a platform for joint consultation, joint construction and sharing, enhance the innovation ability of enterprises, cultivate a team of high-quality talents, promote the overall development of the industry, and stimulate the vitality of the market.
