摘要

The roof has a ruled curved surface in a shape of hyperbolic paraboloid having row of tubes (1) placed side by side and supported on two opposite beams (2) of four beams of a support. The row of tubes are connected by flexible plates or by a slab (3) inserted between the two adjacent tubes. The curved surface is made up of flexible cloth stretched on the support.
