<p>Fermenter tank of a biogas plant having vertical side walls, comprises an adjacent sealing film present inside the fermenter tank, with which the fermenter tank is lined until above the upper edge of the side walls, and a tented roof made of at least one roofing foil, which is tightly attached at the upper edge of the side walls. The upper edge of the side wall is formed as wall crown by a longitudinally extending U-shaped beam with downwardly directed U-shaped shank and an approximately horizontal upper U-shaped base. Fermenter tank of a biogas plant having vertical side walls, comprises an adjacent sealing film present inside the fermenter tank, with which the fermenter tank is lined until above the upper edge of the side walls, and a tented roof made of at least one roofing foil, which is tightly attached at the upper edge of the side walls. The upper edge of the side wall is formed as wall crown by a longitudinally extending U-shaped beam with downwardly directed U-shaped shank and an approximately horizontal upper U-shaped base. An upwardly protruding threaded bolt series with respectively spaced threaded bolts is attached at the U-shaped base. The edge side of the sealing film exhibits a row of holes corresponding to the threaded bolt series, with which the sealing film is connected with an edge strip at the threaded bolt. The roofing foil also exhibits a peripheral row of holes corresponding to the threaded bolt series, with which the roofing foil is connected with an edge strip above the sealing film at the threaded bolt. At least one sealing strip with a row of holes corresponding to the threaded bolt series is inserted on the threaded bolt. The sealing strip is screwed with screw nuts such that the edge strips of the sealing film and the roofing foil are clamped between the U-shaped base and the sealing strip and/or between the sealing strips, for a thick wall connection.</p> |
