The present invention relates to a cover construction, such as e.g. a weather protection device for building sites or the like, comprising a number of beam members (5, 6) and connecting pieces arranged to be assembled into a number of frame bows formed by upright lateral beam members (5) and roof beam members (6) interconnected therewith, the lower ends of said lateral beam members being supported on a supporting surface (14, 17) the frame bows (2) being retained in spaced-apart relationship by means of spacer poles (3, 4) and the construction is arranged to support covering means, such as e.g. a flexible cloth. In accordance with the invention the supporting surface on which said lateral beam members rest is formed by a rail (14) extending transversely relative to the frame bows, and at their lower ends, said lateral beam members (5) are formed with runner wheels (15) the periphery of which at least partly enclose the track-forming face of said rail, i.e. the upper face thereof. |
