FIELD: construction. ^ SUBSTANCE: invention is related to the field of construction, namely, to designs of smoke stacks, but may also be used to erect, repair or reinforce different construction structures. Some stack with sheet reinforcement created by concrete structure reinforced by sheet reinforcement, in which sheet reinforcement is made of separate high-strength strips, which are fixed along circumference and along generatrices of pipe surface with the help of glue, thus creating cross and longitudinal reinforcement. At that ends of longitudinal strips after their pre-stressing are fixed with anchors fastened in pipe wall, and ends of cross pipes are connected to each other so that their pre-stressing is provided. ^ EFFECT: provision of high manufacturability in erection of smoke stacks and repairability in case of construction structures reinforcement. ^ 1 dwg |
