Abstract
A covered structure is formed in an arched shape and utilizes PVC pipe which is slidable through sleeves electrically welded to a cover. The PVC pipe is bent into an arched shape and is attached to spreader bars which serve as the ground contacting portion of the structure. Fiberglass rods are inserted within the arched PVC pipe so as to both strengthen and define the arch, and water bags and stakes may be attached to the spreader bar, which is also constructed of PVC pipe, so as to anchor the structure to the ground. This construction provides for a flexible covered structure which will not be destroyed by external forces, such as wind, rain, etc., since only resilient materials are used in its construction. Additionally, building code requirements which relate to the method of attachment of a structure to the ground are not applicable since a direct attachment between the structure and the ground is not required.
