<p>A gliding bed (1) for a concrete slab (2) comprises a first film (4) and a second film (5), wherein the first film (4) can be brought into contact with a base structure (3) of the concrete base slab (2), and the second film (5) can be brought into contact with the under side of the concrete slab (2) by means of pouring the concrete onto the second film (5). Said films (4, 5) are tightly connected to each other at edges (7). In order to minimize friction between the concrete slab (2) and the base structure (3), a gas- and liquid-permeable layer is placed between the films (4, 5) and is constructed from a nonwoven fabric (6) and/or a textile sheet, woven fabric, knitted fabric, or meshed fabric.</p> |
