China News Service, Chongqing, July 14 (Han Lu, Jiang Tianyu, Wang Lei) The fastest three days to build a floor, only 7 national-level patents have been applied for... The reporter was on the 14th in China Construction Third Bureau in Chongqing One of the project sites saw that the first domestic "residential building machine" jointly developed by the China Construction Third Engineering Research Institute and the China Construction Third Engineering Corporation has been officially put into use.
"What we call a "residential building machine" is an intelligently controlled large-scale combined mechanical equipment platform that integrates functions such as building outer protective frames, construction layer retractable awnings, hydraulic distributing machines, formwork hanging, pipeline spraying, etc. Xu Guowei, Director of the Formwork Research Office of the Engineering Technology Research Institute of China Construction Third Engineering Bureau and the Third Company, told reporters that the “airborne building machines” previously used by the Chinese construction industry were mainly used in urban landmark buildings above 300 meters in height. And improvement, this'residential building machine' we designed is suitable for the construction of high-rise buildings over 100 meters."

The reporter saw at the project construction site that the "residential building machine" covered multiple structural layers at once. When the main structure of the outer frame was being constructed, the bottom of the outer frame could be interspersed with decoration and other multi-process operations at the same time. This also turns the project under construction into an "air mobile factory" that can be continuously increased with the building structure. "Residential building machine" has also set up a telescopic awning above the working floor, which can maintain a relatively closed environment in the working floor when it rains and high temperatures, providing construction workers with a more comfortable and humanized working environment.
"The support point of the formwork system of the "residential building machine" is lower than the newly poured concrete layer by 2 to 3 structural layers. The concrete age is longer and the bearing capacity is higher. Therefore, the climbing of the formwork system is basically not affected by the bearing capacity of concrete As a result, the construction speed has greatly increased." Zhang Zhihua, deputy general manager of the Southwest Branch of China Construction Third Engineering Bureau and the Third Company, told reporters that the current "residential building machine" only needs 80 to 90 minutes to lift a 3-meter operating floor height; The fastest construction speed takes only 3 days to build a floor. Compared with the previous 6 days, the time is shortened by half. "Most of the equipment materials of the "residential building machine" are designed with assembled nodes, and the recycling turnover rate is more than 90%. In the next commissioning, only a small amount of non-standard components need to be assembled."
