Support Corbel JBA
If the parapet slab is located above the uppermost or below the lowermost ceiling slab, it is also called a parapet or apron. JBA support corbels are available in normal and parapet versions. In the standard version, the reinforcement bars for connecting the reinforced concrete element point upwards, while in the parapet version they point downwards. In custom designs, the reinforcement bars can also be welded on at variable heights. Both versions are also available in adjustable variants. The JBA support corbel can be raised or lowered on the compression bearing (front sliding bearing A) using the levelling pin JGW.
