DE-MOUNTABLE TENSIONED MEMBRANE STRUCTURE

摘要

A de-mountable tensioned membrane structure (100) is erectable to cover a zone (1000). Outer frames (30) with support arms (31) supported on brackets (11) on concrete footing members (10), have the posts (51) of respective inner frames (50) suspended therefrom. The membrane (70), interposed between the outer and inner frames (30, 50), has low points (73) connected to the footing members (10) and high points (72) connected to the ends of support arms (55) of the inner frames (50). The inner ends of the support arms (55) are pulled down the posts (31) to cause the support arms (55) to swing outwardly to cause the membrane (70) to be tensioned.
