Abstract: A frame structure comprises a plurality of parallel, spaced apart, arched frame assemblies composed of pairs of frames. This enables existing frame members to be used for longer spans and/or stronger structures. The pairs of frames are connected together at spaced apart positions. Conveniently the connections between frames occurs adjacent to the ends of sections forming the frames and a combined arrangement can be used for connecting frames and joining sections. Fabric panels extend between the frames of a pair and between pairs of frames. The panels have integral tensioning means. The frames are pivotally fastened to ground support means.

Abstract: A viewing structure comprising a plurality of parallel arched frames, pivotally mounted at their ends on the ground, each frame having a front portion, a top portion and a rear portion. The front portion is generally arcuate, with straight top and rear portions joined by a further arcuate portion. The top portion inclines upward and rearward and support pillars are mounted on each top portion, spaced apart along the top portion. Seating members are mounted on the pillars and flooring members are provided between the pillars. The spaces between arches can be filled by fabric panels. The clear space beneath the structure can be used for food concessions, washrooms and other uses.

Abstract: A frame supported structure with fabric panels is formed from a plurality of spaced arched frame members pivotally attached at their lower ends to ground plates. The ground plates are fixed in position prior to erection of the frames. The frames have open slots on each side into which slide beaded or roped edges of the fabric panels. The frames can be erected from or near ground level, and then the fabric panels pulled in along the slots, from ground level. Cranes or scaffolding are not required. After the panels are in position they are tensioned, as by inflating inflatable sections extending for the length of a panel.
