CONSTRUCTION ELEMENT (VERSIONS) Russian patent published in 2024 - IPC E04C3/07 E04C2/38 E04B1/24 

FIELD: construction.

SUBSTANCE: group of inventions relates to structures of metal thermal profiles used as bearing elements of various frames of wall panels. Construction element is made in the form of a U-shaped plastically deformed, bent or rolled metal profile with a longitudinal perforated wall, including staggered thermal holes, and side shelves. Longitudinal wall in one version is made convex with formation in section of isosceles trapezoidal tenon with smaller base outside, and in another version—concave with formation in section of isosceles trapezoidal slot with smaller base inside, on which there are thermal holes made in the form of notches with flanges directed inward or outward of the profile.

EFFECT: construction elements are characterized by strength, spatial stability of shape and operational reliability, including their simultaneous joint use in creation of wall panels that are technologically advanced in production, having the possibility of simple and reliable docking and connection to each other using angular joints created on the basis of the same building elements.
