METHOD OF REINFORCING REINFORCED CONCRETE BEAMS USING POLYMER COMPOSITE PROFILE Russian patent published in 2024 - IPC E04G23/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to the reinforced concrete beams reinforcement method. Method of reinforcing a reinforced concrete beam using a trough-shaped profile from a polymer composite material, attached to the lower edge of the beam, consists in the fact that on the prepared surface of the working reinforcement located in the lower edge of the beam, paired steel short pieces with a bolt fixed in them are fixed by means of welding with pitch S. Then, through pre-drilled holes in the trough-shaped profile, it is fixed with bolts so that the inner cavity filled with polymer concrete closes the working reinforcement from external action and creates a waterproof barrier.

EFFECT: high strength of the reinforced beam.
