HALFEN HBJ-W – Betojuster for precast concrete wall elements The HALFEN HBJ Betojuster is an auxiliary device for adjusting and aligning precast concrete elements; especially suitable for aligning wall elements, prefabricated garages and concrete form shapes. The HBJ Betojuster provides the building contractor with a simple and therefore a safe method for precise vertical adjustment of walls after initial installation; while simultaneously avoiding injuries to site personnel and avoiding tool damage to concrete elements. Adjustment requires minimal eort and is done with standard tools. The minimal...

Precast plant assembly Two betojusters are installed ush with the underside of the concrete wall element. The screw socket is fully recessed in delivery state and during the initial installation. Attach to timber formwork with nails or to steel formwork using hot glue. Variant 1: sandwich-walls, post-filled with concrete In sandwich-walls the HBJ is installed only in one shell (preferably in the inner shell). The required edge reinforcement is installed o-set behind the HBJ. ls,min Variant 2: monlithic walls The betojuster is xed to the formwork with an additional wood batten; this forms a deeper...

On-site assembly The wall is initially installed by crane and secured with shoring. The shoring elements support the stresses caused by eccentric forces during installation. The provided pressure distribution blocks are placed under the individual HBJ. Apply spanner here ➀ Construction elements must be properly secured pressure distribution block (included in delivery) 24 mm ratchet spanner-wrench Concrete slab ➀ Retaining plate for the hexagon screw socket Both HBJ are adjusted until the side joints are parallel, the wall is horizontal aligned and the desired wall height has been reached. Finally...

HALFEN HBJ-S – Betojuster for columns The HALFEN HBJ-S Betojuster is the ideal device for adjusting and aligning concrete elements: • precast reinforced concrete columns with formed foundation • road surface- and railway-platform slabs • stairs • precast foundations The HBJ 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. Two variants of HBJ-S Betojuster are available. HBJ-S-V for vertical assembly and HBJ-S-H for horizontal assembly into formwork. Both variants are available...

On-site assembly The crane lifts the column into position with the weight of the column resting on a central pin or bearing-plate. Adjustment is carried out by rst tilting the column in one axis by turning (clockwise or anti-clockwise) one HBJ-S on this axis. The foot moves out of the tube by turning the adjustment-screw anti-clockwise. Next the column position is secured by turning the second HBJ-S on this axis evenly onto the blinding layer. Adjusting in the other axis is done according to the same principle. When adjustment is completed, owing concrete is poured through one pour hole until...
