They ensure that the load transfer is correctly through the centre of the horizontal joint thus eliminating any chance of fretting at the edge due to the rotation of the slab. Live load deflection of the slab by means of settlement of adjacent columns/walls and piers is also diminished. Applied in a continuous length they are ideal for both reinforced and post-tension slabs in car parks, shopping centers, airports, hotels and recording studios. Description Slipjoints are manufactured of polished stainless steel sheet sliding on a PTFE layer bonded to a high performance quality rubber strip. The slipjoint is finished with polystyrene to give the required width and then sealed with adhesive tape. Advantages „ Standard movement capacity up to ± 50 mm „ Load capacity ranges from 75kN/mtr to 500kN/mtr „ Accommodates initial shrinkage and subsequent thermal movement while being noiseless „ Gives loading at a centralized area that eliminates edge loading Specifications When specifying please include details such as load capacity kN/mtr, movement capacity, total width of corbel. Example of a SJ100/15/150 slipjoint – SJ100 Load Capacity 100kN/mtr of Slipjoint 15 Movement capacity is +/- 15 mm 150 Width of Corbel is 150 mm Installation 1. Prepare suface of concrete/brickwork to receive the Slipjoint so that it is level and sound. 2. Hold the slipjoint in position using contact adhesive and seal any butt joints with tape. 3. Make sure the complete surface of the concrete seating is covered with slipjoint and polystyrene foam. Do not forget to allow for any expansion joint materials, if specified. 4. Placement of concrete should be done with care making sure no damage is done to the slipjoint with vibrators, etc. September 2007
