Connolly Universal Dowel Sleeves are available for round and square dowels, to allow for load transfer across joints in slab-on-ground applications.
The sleeve encases one half of the dowel to de-bond the dowel from the concrete. All Connolly Universal Dowel Sleeves allow for expansion and contraction at the joint. Square dowel sleeves also allow for lateral movement at the joint.
The Universal Dowel Sleeve is equipped with a patented, integrated support leg, which can be adjusted to suit multiple slab heights. This unique feature assists with accurate dowel alignment.
With the included nailing plate, they can also be connected to conventional formwork.
Injection moulded from polypropylene for accuracy and straightness, the UDS range minimises the vertical movement across the joint.
All our sleeves are colour coded for ease of identification.
For use with formwork:
Flick a chalk line along the form board at the centre of the slab thickness. Nail the face fixing caps onto the form board with the supplied nails. Insert sleeves onto the fixing caps prior to pouring the concrete. To make the job easier the sleeves can be installed after the reinforcement has been laid and chaired. The face fixing caps can also be screwed to steel formwork using self-drilling screws.
When concrete has hardened, the form board can be stripped to expose the open end of the sleeves.
If specified apply expansion material to the slab face and insert the appropriate dowels into the sleeves as the next pour is being prepared. To eliminate tripping, the dowels can be installed after the groundwork has been completed for the adjacent pour.
For use of Universal Dowel Sleeves in conjunction with other Connolly jointing solutions, please refer to the appropriate installation instruction.
