Wall or floor covering ceramic split panel pair - comprises two trapezoid panels with equal and unequal base lines

摘要

Two elements make up a set of panels used in covering walls or floors esp. ceramic split panels. Both are in the form of trapezia, with base lines symmetrically combined in plan shape. In both, the height and slope of the trapezia's side lines are the same. Trapezia of one type have base lines of different length while those of the other have base lines of equal length. Base lines of both types may be in a length ratio of at least 3 to 5 times a grid dimension.
