REINFORCEMENT UNIT INSTALLATION METHOD Russian patent published in 2006 - IPC E04G23/00 

FIELD: building, particularly to reinforce building structure.

SUBSTANCE: method to install reinforcement unit made as covering yoke composed of angle members and strips around building structure, for instance around column, involves arranging the yoke on concrete or grout bed; providing necessary gap between contact surfaces and compressing reinforcement section of the yoke by pulling angle members and strips together by welding operation. Inner surfaces of angle members are preliminarily primed with mount grout and then covering grout is applied over the mount grout. Angle members are located on column surfaces covered with the grout and are pulled together by jack to provide close contact between inner surfaces of angle members and the column through the grout. Non-combustible plates are arranged in gaps between side ends of angle members. Yoke strips are put onto non-combustible plates and welded to angle members in two stages. At the first stage two pairs of cold strip sides extending along one column diagonal are welded and then the strips are heated up to 400-450°C. At the second stage remainder two pairs of two strip sides located along the second column diagonal are welded.

EFFECT: increased reliability and safety of the structure.
