THREE-CHAMBER WALL CONSTRUCTION PROFILE Russian patent published in 2019 - IPC E04B2/14 E04B2/86 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to elements of building structures, and can be used as a fixed formwork for monolithic construction of buildings and structures. Technical result is achieved by the fact that the three-chamber wall construction profile includes lateral parallel spaced longitudinal walls connected by perpendicular partitions, and two partitions arranged parallel to the longitudinal walls, forming three cavities to accommodate the structural material, and in perpendicular partitions of the extreme cavities there are holes for pouring concrete, with the side longitudinal walls, connected by partitions, form an elongated hollow volumetric figure of rectangular section with openings in its four sides, moreover, two parallel openings are provided with retaining elements, made in the form of shaped grooves-hooks, placed along the entire length of the edge of each longitudinal wall of one opening with the possibility of connection with the grooves-hooks of the longitudinal walls of the parallel opening.

EFFECT: technical result is to increase the reliability of the connection of multi-chamber wall building profiles.
