Corbel/slab interfaces where a low friction sliding interface is required. Granor Slipjoint provides a predicable low co-efficient of friction at the interface. Between the corbel and the slab.
Ensures that the load transfer is correctly through the centre of the corbel, eliminating any chance of fretting of the corbel edge due to settlement and / or rotation of the slab.
The very nature of the centralized elastomeric bearing strip automatically provides load transfer to the corbel away from the edge of the seating. Live load rotation / deflection of the slab or deflection by means of settlement of adjacent columns/walkways/walls/piers, fretting of the concrete is eliminated by the use of GRANOR Slipjoint.
Continual shortening and / or thermal movements of the slab can build up until slippage occurs at the rough concrete interfaces complete with a creaking or cracking sound. Such is eliminated by the use of the noiseless SJJ Slipjoint. Important in quiet buildings such as recording studios, hotels, hospitals, or funeral parlors.
In order to easily identify supplied items, part numbers and intended location of the product, is clearly marked by way of part number and installation location.
Slipjoint can be supplied with the stainless steel top offset compared to the elastomer bearing strip thus providing for what is typically greater shortening due to shrinkage and thermal contraction than expansion.
Can be cut to length on site however it is recommended that Granor supply units of the exact length required.
