FIELD: construction industry. ^ SUBSTANCE: invention refers to the field of construction industry, to device for renovation or reconstruction of multistory building or construction in particular. Mentioned engineering result is achieved due to the following: device includes column, mainly metal, which is installed adjoining to side vertical member with possibility of assembly and disassembly, and it is designed open, passing through floors at least one level up and one level down from zone of collapse. Ends of column are connected to undamaged side vertical members of above and below levels by temporary bracings. On column section located in zone of collapse power mechanism is installed. Columns may be installed as several parallel rows located at least opposite to each other and connected to each other by beams in lengthwise and crosswise directions with formation in plan view of at least rectangles, apices of each of them are connected diagonally by braces, at that power mechanism is installed in zone of collapse in each column. ^ EFFECT: decrease of efforts required for renovation or reconstruction of multistory building or construction upon improvement of reliability and reduction in consumption of materials. ^ 2 cl, 2 dwg |
