ABSTRACT:
The roof structure includes a pair of cables (10, 12) intersecting at right angles to provide four cable segments and four quadrants, and clamping means clamping adjacent corners of four fabric panels (80) in the four quadrants, the clamping means including four elongated base plates (24, 34, 44, 54) mounted respectively on the four cable segments, each base plate (24, 34, 44, 54) having a pair of elongated lower clamping plates (60, 70) extending respectively along opposite longitudinal edge portions thereof, and each lower clamping plate (60, 70) having an elongated upper clamping plate (64, 74) secured thereto and clamping an edge portion of one of the fabric panels (80) therebetween. Only one end portion of each of the base plates (24, 34, 44, 54) is secured to its cable segment, and clearances between parts adjacent the cable intersection allow a limited amount of relative movement between the parts to provide stress relief in the fabric panels (80).
