METHOD FOR REINFORCING A REINFORCED CONCRETE COLUMN OF RECTANGULAR OR SQUARE SECTION Russian patent published in 2022 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to the reinforcement of both new reinforced concrete columns, in which technological errors were made during the manufacturing process, and destroyed or damaged during operation due to the influence of negative factors. The substance of the invention lies in the fact that a method for reinforcing a reinforced concrete column of rectangular or square section, including a formwork around the column, subsequent concreting with fine-grained self-expanding concrete, while first rounding the corners of the column cross section, then cleaning the surface of dust and damaged concrete, priming the surface, and after the formwork and subsequent concreting, the formwork is removed and wrapping with composite materials is carried out in the transverse direction, while the formwork is arranged without a gap, close to the rounded corners of the column, and the composite material is glued to the rounded sections of the concrete casing.

EFFECT: increasing the strength of concrete of an existing reinforced concrete column by restraining the development of transverse deformations of concrete.
