AlphaJoint Classic Universal 4010 joints are designed mainly for concrete jointless floors, because they also act as a working break and as a leave-in-lace formwork, but they can be also easily used in cut concrete floors.

PERMABAN AlphaJoint® Classic Universal 4010 expansion profiles as a precursor are certainly the most well-known expansion joints on the industrial floor market, distinguished primarily by high quality and reliability. Intended for indoor applications, for floors exposed to high loads. They ensure free horizontal movement of adjacent concrete slabs and prevent any vertical movement of these slabs, also protecting their edges. Load transfer between adjacent concrete slabs is ensure with plate dowels.
This model is available from the so-called "universal" divider plate, which can be lowered to the ground, it is suitable for slabs 150-200mm. Ensure load transfer between adjacent concrete slabs with plate dowels.
Massive cold drawn, square edge steel profile 4010 - 10mm wide and 40mm high, so-called. "4010" protects the edges of jointed floor slabs from crumbling because they are exposed to the impact of passing forklift wheels through the expansion joint openend.
TD plate dowels ensure the transfer of loads between floor plates, enabling the horizontal movement of concrete plates, while preventing any vertical movement of these plates relative to each other at the expansion joint. Expansion joints are available with one of three types of load-bearing plate dowels: TD6 6 mm thick, TD8 8 mm thick or TD10 10 mm thick. These dowels are of the same shape and differ only in thickness.
Divider plate consists of two steel sheets, lower one after
installing the profiles at the appropriate height (floor level), can be lower down to the ground. This prevents concrete from flowing out under the mounted one
profile to the other side. It allows the same product to be used for different slab height.
The profiles are connected with peel rivets (frangible fixing system), which break during concrete contraction, allowing expansion joints to open and compensate for this shrinkage. Shear studs ensure steel elements anchoring on each side of the joint. After rivets breaking, in one concrete slab stays: the upper square edge steel bar, sheet steel formwork and plate dowel. In the second concrete slab stays the second upper square edge steel bar and the dowel sleave from which the dowel has already slipped out as far as the slabs have moved apart compensating concrete shrinkage.Even in extreme situations with a 30mm joint opening, TD plate dowels still transfer loads from one plate to another and prevent plate deadlock.
The length of one profile is 3m. Profiles can be cut anywhere.
AlphaJoint Classic Universal 4010 expansion joints are in standard made of natural steel, but you can also order profiles in the version with galvanized square edge upper bars 4010.
This model - AlphaJoint Classic Universal 4010 - is available from "Universal" separating plate, which can be lowered to the ground in the case of floors with a height of 150-200mm.
