FORMWORKING SYSTEM FOR PREMIUM-MONOLITHIC CONCRETE WALLS - DIAPHRAGM OF RIGIDITY Russian patent published in 2021 - IPC E04B2/84 E04G11/08 

FIELD: construction.

SUBSTANCE: Formwork system for precast-monolithic concrete walls-diaphragms of stiffness, containing a truss of C-shaped steel profiles, obtained by connecting several C-shaped steel profiles (1) with horizontal reinforcement (2); C-shaped steel profiles (1) are provided with through holes on two lateral vertical sides; rivet nuts (3) are installed in the through holes; clamping screws (20) are screwed into the rivet nuts (3) at one end, and sealing support elements are put on the clamping screws (20); the sealing support elements comprise an inner part (4) and an outer part (5) of the sealing support elements; the inner parts (4) of the sealing support elements consist of a three-section sleeve with a gradually decreasing outer diameter from the inside to the outside, while its outermost section is provided with an external thread; the outer parts (5) of the sealing support elements are a nut.

EFFECT: provides a more stable quality of monolithic concrete walls, while the quality of precast-monolithic concrete walls is ensured simultaneously with a decrease in the cost of construction.
