Multi-layer flexible panel modules with exterior and interior stressed layers spread apart at the ends and connected intermediate the ends inducing opposing concave deflections to the layers

摘要

A lightweight building construction system comprising multiple similar stressed roof and wall paneling modules (22, 122) assembled together to form a modular building envelope. Each roof module (22, 122) typically includes a double-skin panel (1,4/101) having structurally interacting inner and outer layers (4,3/104,103) joined together at mid-span and stretched in a V-shaped configuration between spaced-apart structural elements (9, 109). A linear gutter (2) can hang from the double-skin panel (22) at the junction of the inner and outer layers (4,3) thereof to drain water, thereby preventing ponding problems. The stressed paneling modules (22) may be supported by lightweight non-rigid tensely arched members (15, 16).
