The cone has an inner scaffold (1) and an outer scaffold (2) that are covered in gas-tight and waterproof manner. A film/tarpaulin (3) is formed between the inner and outer scaffolds. The inner and outer scaffolds comprise profiles, where the profiles and the film/tarpaulin are adaptable for different applications. Protection plates (5) are arranged between the profiles of the inner and outer scaffolds and made of plastic or metal. The inner and outer scaffolds are interlocked by a screw or press connection (4) to form a gas-tight and waterproof connection. |
