METHOD OF MANUFACTURING CONCRETE TUBULAR BUILDING ELEMENTS |
| 摘要 |
In order to dismantle during the manufacture of a concrete building element (3) the casting in a simple and reliable manner without damage, so that the casting mould (5) can be rapidly used for a next manufacturing process, the upper gauge (9) of the casting mould is retained against the still incompletely cured concrete mortar (10) of the casting, whilst the casting is removed from a core (8) and a jacket (7) of the casting mould (5). |
