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.2 dwg |
