ALUMINIUM FLOOR TO FLOOR EXPANSION JOINTS
PURPOSE
This is used for the expansion gaps between floor to floor. It features a durable architectural aluminium base frame and cover which helps in avoiding leakages through the expansion joints.
ADVANTAGES
- Accommodating thermal changes to prevent cracking.
- Absorbing vibrations from machinery and seismic activity.
- Preventing damage by reducing stress and fractures.
- Ensuring durability and minimizing costly repairs.
- Facilitating structural movement in response to load variations.
- Enhancing safety by preventing sudden failures.
- Adapting to interactions between different materials in construction.
METHODOLOGY
- Clean the surface of the 'mother slab' thoroughly to a width of 4 inches / 100 mm on either side of the expansion gap. Grind any uneven surface and smooth finish. Remove the dust particles using an air blower.
- Apply a thin coat of polymer based adhesive supplied by Arpitha exports, which is suitable for fixing the PVC water barrier to the concrete floor, on the cleaned surface and affix the PVC water proof sheet by pressing firmly without allowing any air pockets.
- Then 6 inches / 150 mm width Arpitha Plaster Mesh provided by Arpitha Exports is spread on the affixed PVC water proof sheet firmly all along and nail to the mother slab. Then apply a thin coat of cement mortar. Allow curing for one or two days.
- Fix the Aluminium profile on either side of the expansion joint gap to the final required level of the floor with thescrew & cement mortar.
- The same procedure is followed for the other side of the expansion joint gap.
- Insert the expansion pin through the slot provided in the fixed aluminium profile connecting the aluminium profiles fixed on either sides.
- Finally place the Aluminum plate provided by Arpitha Exports on top, and fix it to the inserted expansion pin through the holes provided in the top Aluminum plate.
