FIELD: construction. ^ SUBSTANCE: method to erect a dome roof includes radial installation of flat trusses with a pitch along the roof perimetre, and their upper belt forms a shaping circuit of the dome. On the upper belt of trusses a formwork net is fixed with a cell size of 3-6 mm, a reinforcement frame of a reinforced concrete shell is installed, and a coarse net is laid with a cell size of 15-20 mm. Concreting of the reinforced concrete shell is carried out by concrete mix gunning on top to form an external protective layer of at least 10 mm. After hardening the protective layer of the shell is impregnated with a polymer composition, a layer of hydraulic insulation mastic is applied, above which a decorative mosaic coating is laid from smalto tiles. ^ EFFECT: reduced labour intensiveness and material intensity. ^ 2 cl, 1 dwg |
