Description
Advantage:
- The STSR double-threaded screw is supplied pre-assembled with EPDM gasket, tightening nut and pair of nuts for connection to the MW or SSP brackets.
- Quick installation because the roofing must not be removed during installation.
- Due to the EPDM gasket, the waterproofness of the roof is maintained.
Application Area:
- Concrete beams and slabs
- Brick and concrete ceilings
- Wooden beams
Suitable for corrugated panel roof systems with:
- SolarFish H33
- SolarFish H44
- With FIS V chemical anchor on concrete beams and slabs
- With FIS V chemical injection mortar and FIS HK injection anchor sleeve in brick and concrete ceilings
- Directly on wooden beams after drilling the pilot hole
Application Notes:
- Identify the length of the STSR double-threaded screw depending on the thickness of the load-bearing structure.
- Determine the centre distance of the STSR double-threaded screws according to the snow and wind loads of the installation area and inclination of the roof.
- Identify the position of the STSR double-threaded screws depending on the load-bearing structure and the layout of the installation.
- Drill the support according to the diameter of the screw and the type of support.
- Fix the STSR double-threaded screw to the structure by putting the EPDM rubber in contact with the roof.
- Tighten the MU nut on the gasket to maintain waterproofness.
- FIx the SSP or MW connection plate, adjusting its height using the MU F nuts.
- Carefully seal the exit point of the screw from the roof with bituminous sealant.
