Method for producing double floor

摘要

On site, empty troughs (1) are positioned and levelled by means of supports (4) on the rough floor, clay material then being placed in them. The troughs are actually overfilled with clay material and after the material has hardened it is ground off so that the troughs can be individually withdrawn. The intermediate space between the individual trough is sealed before introduction of the clay material. On the edge area of adjacent troughs before filling a strip or profile is laid. The profile (7) has a U-shaped cross-section.
