MEMBRANE COVER ELLIPTICAL IN PLAN Russian patent published in 1994 - IPC

FIELD: construction. SUBSTANCE: membrane cover includes four inclined arches of external supporting contour resting in pairs on four foundations, two inclined frames supporting central spatial latticed structure of zero Gauss curvature and four membrane shells with negative Gauss curvature with shape forming orthogonal lattice. External arches are inclined at angle of 50-65 deg. to horizon and form four gate openings for passing aircraft into hangar. Inclined frames consist of horizontal cross bars and inclined posts whose tops are connected by guys of strip steel with foundations of adjacent contour external arches. EFFECT: optimized internal space of hangar and reduced consumption of materials, and improved service properties of hangar cover. 6 dwg
