Abstract

The present invention is system for covering structures that have complex surfaces using tensioned membrane panels which exhibit maximum flexibility over multiple curvatures of the structure's surface. The system includes a means for supporting the cladding membrane over the structure, a means for tensioning the cladding membrane and a means for securing the tensioned cladding membrane to the structure. Generally, ribs are mounted to the structure wherein the ribs provide support for the cladding membrane. Attached at least one of the ribs are clamping channels which secure the tensioned cladding membrane to the structure. The ribs can be thermally isolated from the building surface to minimize directly conducted heat loss. Additionally, the tensioned membrane cladding system usefully accommodates various methods of applied insulation between the cladding membrane and the structure.

Dependent claims

an apparatus for cladding the exterior surface of a structure which is curved, wherein said apparatus is comprised of:

(a) a tensioned cladding membrane, wherein said tensioned cladding membrane has a proximal end, a distal end, and an intermediate portion disposed between said proximal end and said distal end;
(b) a standoff member which is contiguous with said intermediate portion of said tensioned cladding membrane but is not attached to said tensioned cladding membrane;
(c) a first tensioned cladding membrane attachment member which is contiguous with and attached to said proximal end of said tensioned cladding membrane;
(d) a second tensioned cladding membrane attachment member which is contiguous with and attached to said distal end of said tensioned cladding membrane, wherein:
1. said standoff member is disposed between said first tensioned cladding membrane attachment member and said second tensioned cladding membrane attachment member;
2. said tensioned cladding membrane is disposed between said first tensioned cladding membrane attachment member and said second tensioned cladding membrane attachment member, said tensioned cladding membrane is attached to said first tensioned cladding membrane attachment member at said proximal end of said membrane, said tensioned cladding membrane is contiguous with said standoff member at said intermediate portion of said membrane, and said tensioned cladding membrane is attached to said second tensioned cladding membrane attachment means at said distal end of said membrane,
3. from the proximal end to said standoff member, said tensioned cladding membrane forms an arc with a substantially continuous concave curvature, and
4. from the distal end to said standoff member, said tensioned cladding membrane forms an arc with a substantially continuous concave curvature.
