Sika® CarboShear® L, type 4/20/50
Carbon fibre shear links for structural strengthening as part of the Sika® CaroboDur® carbon fibre-reinforced polymer (CFRP) strengthening system.
Application
Used to improve, increase or repair the performance and shear resistance of structures for:
Increased load carrying capacity:
- Increasing the load capacity of beams;
- For the installation of heavier machinery;
- For changes in building use.
Damage to structural elements due to:
- Deterioration of the original construction materials;
- Steel reinforcement corrosion;
- Accidents: vehicle impact, earthquakes, fire etc.
Improvement of serviceability and durability:
- Reduced deflection and crack width;
- Stress reduction in the steel reinforcement;
- Improved fatigue resistance.
Change of the structural system:
- Removal of walls and/or columns;
- Removal of floor and wall sections to create access/openings;
- Changed design philosophy.
To repair design or construction defects such as:
- Insufficient / inadequate reinforcement;
- Insufficient / inadequate structural depth.
Description
Carbon fibre shear links for structural strengthening as part of the Sika® CaroboDur® carbon fibre-reinforced polymer (CFRP) strengthening system.
Designed for strengthening concrete structures in shear and to anchor Sika® CarboDur® plates at their ends.
Features and benefits:
- Tested anchorage system.
- Non-corroding.
- Very high strength and durability.
- Shear and bursting enhancement.
- Well defined anchoring.
- Lightweight.
- Low overall thickness, can be over coated.
- Easy transportation.
- Easy installation – no heavy handling and installation equipment.
- Outstanding fatigue resistance.
- Minimal preparation of the shear links is required.
- Minimal aesthetic impact.
- Sika® CarboShear L shear links are bonded as external reinforcement using Sikadur®-30 epoxy resin-based adhesive for normal temperatures during application.
