JOINTS:    ALPHAJOINT     i     ALPHAJOINT CLASSIC

AlphaJoint

AlphaJoint and  AlphaJoint Classic are used in heavy-duty floors (big loads) – they provide free horizontal movement of adjacent floor slabs during the concrete contraction, thereby eliminates the risk of floor cracking. Those joints are used on jointed and jointless, steel fibre and mesh reinforced ground bearing slabs or bar reinforced suspended floor slabs on piles.

Joints are ideal as a daily formwork – it allows you to stop concrete pouring in each moment you need

Joint opening: max. 30mm

Floor arris protection of the concrete floor slab on the both sides of the joint is provided by two top steel strips 10mm wide – this eliminates concrete crushing along the joint gap caused for example by intens forklift traffic.

Load transfer across the joint is provide by Dowel Plats. Dowel Plates also protects floor slab against eventual vertical movement. Joints are available with one of 3 Plate Dowel: TD6, TD8, TD10.
Plate Dowels TD6, TD8 and TD10 have got the same dimensions but other thickness. TD6 Plate Dowel is 6mm thick, TD8 is 8mm thick and TD10 Plate Dowel is 10mm thick.

TYPES:

AlphaJoints are now up to 4x stiffer compare to traditional and from many years used AlphaJoint Classic, it’s because of improvement of Divider Plate.
