Saddle-shaped ceiling, wall or roof panel - with anticlastic surfaces curving concave one way and convex the other

摘要

The lightweight panel, of plastic, sheet metal or cast material, for outside membrane mounting, combining structural and aesthetic qualities, has an even number of adjoining surface areas coming together at any given point so that one slope away is concave and the other direction convex. The periphery is polygonal, with a central structural element in the middle, and bridges formed between the saddle surfaces; the central element may be in various forms. There may be six outside saddle surfaces, with the polygonal periphery in the form of a triangle. In addition to the above qualities there are good acoustic characteristics with high resonance frequencies and low energy transmission, and production costs are low.
