SUBSTANCE: column comprises concrete beam in which main longitudinal reinforcement bars are arranged along the full column length. Included in concrete beam are collars and auxiliary reinforcement made as welded nettings located at ends. Transversal steel sheets are located at column ends and connected to column beam by anchor rods. Rods are not connected with end sheets and have no contact points with above sheets. Secured to steel sheets are vertical steel angle members forming pockets located on steel sheets at column sides. Pockets are symmetric about main column axes. Created in pockets of end sheets are orifices for arranging screw connections to provide joint with upper and lower column. Column may be made as prismatic or cylindrical stem. Transversal steel sheets connected to column ends under vertical angle members in pocket areas may have increased thickness and comprise additional plates. Each column formed as multi-story one has through channels for cast-in-place building floor structures arrangement in column. Column butt-joints including column end parts are provided with transversal sheets connected to ends thereof having centering lining. Transversal steel sheets have shaped edges. Gap between transversal steel sheets is filled with mortar. Butt-joint includes pockets formed at column ends. Steel sheets have orifices in which pins with threads are inserted. Pins are secured on end sheets with nuts. Located in mortar between sheets are aligner nuts. Pockets are caulked by fast-hardening fine concrete. Method of butt-joint forming includes locating and securing lower column; fixing threaded pins on upper end of lower column; screwing aligner nuts on threaded pins; arranging aligner nuts in design position; installing upper column in two stages coaxially above lower column so that upper column end abuts that of lower one and connecting columns. The first stage of upper column installation includes supporting column on aligner nuts; adjusting upper column position up to obtaining demanded position in horizontal and vertical planes. The second stage involves displacing upper column upwards, pouring mortar on lower column end and immediately putting upper column on non-hardened mortar so that upper column rests upon aligner nuts; fixing upper column from upper end thereof by nuts arranged in upper column pockets; caulking pockets with fast-hardening fine concrete and rubbing butt-joint surfaces opposite to sheets with mortar.
