H-BEAM Russian patent published in 2025 - IPC E04C3/14 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to the structures of H-beams used as load-bearing elements of floors and coatings of buildings. H-beam comprises outer flange, inner flange, beam wall, lower coupling structure, upper coupling structure consisting of coupling straps and coupling bars. Outer flange has a larger width compared to the inner flange, the outer flange also has a groove in which the beam wall is installed and binding bars, inner flange is structurally coupled with lower binding structure, which performs function of fastening element, wherein the lower binding structure is installed on the inner flange lower edge on both sides so that a part of the lower binding structure binding pads protrudes beyond the inner flange. In the upper part of the beam there located is the upper connecting structure, which consists of two equivalent binding straps attached by fastening elements and glue to the inner and outer flanges so that some of the straps protrude beyond the flanges.

EFFECT: development of H-beam design having increased bending strength, environmental friendliness, vapour permeability, thermoregulating, fireproof properties and reduced weight.
