Abstract
A sealing strip is provided which is suitable for sealing flat roofs and engineering structures at outer corners. The sealing element is made of a weather-resistant elastomer or plastomer and comprises, in a zone positioned intermediate its ends, at least one pair of areas in the form of oppositely directed waves whose amplitudes and wave-lengths increase regularly from the center line of the strip towards its longitudinal edges so that said zone comprises a planar basal surface and an additional curved a planar sectorial surface corresponding to each wave. The wave-shape areas enable the sealing element to be smoothly laid around an outer corner without straining any areas of the strip.
Claims16
A sealing strip made of a weather-resistant elastomer or plastomer for outer corners on flat roofs and other engineering constructions, which comprises, in a zone positioned intermediate its ends, at least one pair of areas in the form of oppositely directed waves whose amplitudes and wave-lengths increase regularly from the centre line of the strip toward its longitudinally extending edges, so that said zone comprises a planar basal surface and an additional curved aplanar sectorial surface corresponding to each wave.
A sealing strip made of soft PVC or polyisobutylene for corners of flat roofs and other engineering construction which comprises, in a zone positioned intermediate its ends, at least one pair of areas in the form of oppositely directed waves whose amplitudes and wave-lengths increase linearly from the centre line of the strip towards its longitudinally extending edges so that said zone comprises a planar basal surface and an additional aplanar sectorial surface corresponding to each wave.
A rectangular sealing strip of weather resistant material having at least one pair of areas in an intermediate zone defining oppositely directed waves, each said wave having an amplitude and a wave-length increasing from a center line of the strip towards a longitudinally extending edge thereof.
