ABSTRACT:
In order to form a tighter seal, especially at corner butt joints, between polygonal construction plate elements which are pressed together at their edges with an intervening gasket strip, the strip is provided at its critical sealing section with a second material of greater elasticity than the first, main gasket material. A third material which plastically deforms under pressure is partially embedded in the second material. The pressure of the second material when compressed forces the third material to flow into low seal pressure spaces and gaps of the seal to form a bonded seal with a seal pressure which is distributed by the deformation of the third material. Various configurations of the gasket cross-section and of corner segments are described.
