Abstract
The invention relates to a separating device for door cases on floors with different heights, which is used to inject a moisture-proof seal, for example, and which can be anchored in the jointless floor and can be secured to the door cases with a bottom part which has an expansion element. A height-adjustable, connectable top part can be reverse-drawn over the bottom part, the upper surface of the top part being aligned with the upper surface of the higher floor. An adjustable clamping device is used to spread the expansion element of the bottom part relative to the top part, the sealing device being clamped between the bottom part and the top part. The separating device is easy to install and can be flexibly adjusted to various height differences between floors with different heights.
