METHOD TO ERECT ADDITIONAL STORIES FOR BUILDING RECONSTRUCTION

FIELD: construction, particularly working measures on existing buildings. ^ SUBSTANCE: method involves creating orifices in facade walls of basic building so that orifice dimensions provide passage of transversal girders installed at the last building ceiling panel top to create cantilevers; installing posts of the lowest additional story on the transversal girders and on framing belt along building perimeter; creating orifices in building roof to permit post passage; locating removable protective awnings over the orifices; installing additional story frame on the posts and filling frame with filler structure. After that basic building roof and parapet wall are disassembled. Cathead system is installed in upper additional story part along with additional story frame assembling. The cathead system provides movement of telphers to be suspended to girders. All following works for additional story finishing and basic building roof disassembling are carried out with the use of the telphers. ^ EFFECT: decreased building reconstruction time. ^ 6 cl, 4 dwg
