DOME STRUCTURE Russian patent published in 2013 - IPC E04B1/32

Abstract RU 2490398 C1

FIELD: construction.

SUBSTANCE: dome structure comprises a stiff frame with external and internal shells that create a cavity with lower atmospheric pressure. The inner shell is made of textile cloth, and the cavity formed by shells is connected to a fan that maintains in the cavity a previously calculated difference between dome-to-dome and atmospheric pressure, providing for even stretching of the inner shell of the specified spherical shape. The stiff frame is made as collapsible and is formed by a net of triangles.

EFFECT: improvement of structure stiffness.
