DOME-SHAPED ROOF Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: dome-shaped roof consists of small flakes located in two layers. Flake joint units of interior layer are disposed under centers of flakes of exterior layer, and gap between flake layers is filled with warmth-keeping material. Exterior flakes are connected with interior flakes by means of flexible latches. It is two-layer alternation of flakes with gap that makes it possible to increase dome load-carrying capacity which is also augmented due to flake continuous operation. Interlayer joints of flakes in form of flexible latches reduce labor input in dome assembly, and gap between flake layers allows warmth-keeping effected by three methods: adhesion (molding) of warmth- keeping layer to flakes of one layer before installation; insertion of warmth-keeping material (e.g., mineral wool) in course of installation between flake layers; pouring of foaming composition after dome assembly. EFFECT: higher efficiency. 3 dwg
