MOSCOW, December 18. . Experts from Perm National Research Polytechnic University (PNRPU) have developed a building frame construction technology, which increases the speed of monolithic house construction by 10%. The university press agency reported this news.

“Now the frames of such objects are formed using special structures – formwork – these are temporary structures into which fresh concrete solution is poured so that it hardens to the desired shape want. PNRPU scientists have developed a new technology for constructing building frames. it is a combination of traditional methods and innovative 3D printing. This will speed up construction time by 10% and reduce energy costs,” the statement said.

Formwork is an auxiliary structure made of wood, metal and other materials. It is used to give monolithic concrete structures certain parameters – shape and size. For example, with the help of formwork, walls and ceilings are created. Traditional technology involves the use of removable, reusable formwork, which is dismantled after the concrete has gained strength. The authors proposed a construction method using permanent formwork made of concrete with additives, created using a mobile 3D printer that can be moved using a special platform.

“We compared the time and cost of building a building frame using traditional and proposed technology. To calculate the work, we made a work schedule and took into account the market cost of hiring and purchase of formwork and printer sets, wages for workers, and total material costs, the cost of building with a 3D printer is almost no different from traditional technology, even when taking into account its purchase , however, its use allows us to increase speed completed the work by 10%,” said PNIPU Department of Civil Engineering and Materials Science lecturer Stepan Leontiev, whose words were quoted in the message.

The research was conducted within the framework of the Priorities 2030 strategic academic leadership program.
