The HALFEN HBJ-W Betojuster is an adjustment device for aligning
precast concrete wall elements. The HBJ-W Betojuster provides the
building contractor with an easy and therefore a safe method for
precise vertical adjustment of walls, whilst simultaneously
avoiding injuries and preventing tool damage to the concrete
elements. The adjustment process is done with standard tools
requiring little effort. The optimized construction height
keeps the Betojuster in the subsequent floor construction area. It
is not necessary to fill the screw slots.
Quality features are:
Easy, damage free screwable height adjustment
Crane time optimization. Once the elements are placed and
secured with shoring, the crane is available to lift the next
element
Adjustment range up to 35 mm
Requires only standard tools
Minimal effort required
Especially designed for restricted access
HALFEN HBJ-S Betojuster for column elements
The HALFEN HBJ-S Betojuster is an adjustment device for aligning
precast concrete slab elements like
precast columns with sole plate
road surface- and railway-platform slabs
stairs
precast foundations.
The HBJ-S Betojuster provides the building contractor with an easy
and therefore a safe method for precise vertical adjustment of
columns and slabs without using shims or wedges. The adjustment
process is done with standard tools requiring little effort. Once
the elements are placed the crane is available to lift the next
element because for the adjustment procedure the crane-support is
no longer required.
Quality features are:
Easy and safe screwable height adjustment
Crane time optimization - once in position, elements can be
aligned without crane-support
Adjustment range up to 100 mm
Less excavation required for column foundations
Smaller auxiliary space required - less backfill and compacting
required
Adjustment with standard tools
Reduced effort and assembly time
Straightforward assembly near to building extensions and
edges
