FIELD: construction.

SUBSTANCE: reinforcement device includes stressing stands of a steel shell of a column and a spacing unit. The spacing unit comprises support tables, loading screws, thrust elements. The support table is made from a section of a rolled steel angle, reinforced with stiffening ribs, equipped with holes for installation of loading screws. Loading screws are equipped with tension nuts, washers and lock-nuts. The frame of stressed spacers is made of two pairs of steel angles connected by planks. The spacing unit comprises two steel combs installed onto support tables. Support tables are attached to stands of the steel shell at two opposite faces of the reinforced column. Steel combs include thrust plates with loading screws tightly attached to them. Thrust plates are fixed to support parts of joined slab elements. Through rest against thrust plates the loading screws transfer power load to stressed stands of the steel shell, including the latter directly into operation of the reinforced column.

EFFECT: increased reliability of operation, reduced metal and energy consumption.
