A tensile pole tent having improved wind performance, perimeter catenaries, a flexible canopy continuously attached to the catenaries, corner posts to support the catenaries, a membrane interface or field joint between adjacent membrane modules consisting of a novel water-shedding keder rail. The novel keder rail has a high point on its upper surface, that is approximately midway between the channels. The upper surface is preferably convex, however, it may be formed by two or more planar, convex or slightly concave surfaces. A second surface on the other side of the keder rail may also have a high point (i.e. point of greatest distance from the horizontal plane mentioned above) approximately midway between the channels. The membrane interface can be sealed against precipitation by cover flaps that extend upwards from the membrane and come into contact above the interface. |
