Rigid frame structure with tensioned membrane cladding

摘要

A plurality of modular dual arch arrangements are aligned to provide the frame for a shelter. Each dual arch module constitutes first and second arches having their bases spaced from one another and leaning towards one another so that their crests rest against one another. The two arches are hinged to one another at their crests by a hinge. A fabric membrane is positioned over the arches and held in tension through various turnbuckles which attach the membrane to the bases which support the arches. A plurality of longitudinal fabric support bands are stretched longitudinally across the plurality of arches and held in tension to provide further support for the membrane.
