Sika CarboShear L carbon fibre shear link for beam strengthening

Sika® CarboShear L carbon fibre shear links are corrosion resistant, designed for strengthening concrete structures in shear and to anchor Sika® CarboDur® plates at their ends. They are part of the Sika® CarboDur® CFRP Strengthening System.

Sika® CarboShear L shear links are bonded as external reinforcement using Sikadur®-30 epoxy resin based adhesive for normal, or Sikadur®-30 LP epoxy resin based adhesive for elevated temperatures during application. For fixing into the anchorage holes, Sika AnchorFix®-3+ can also be used.

Please refer to the relevant Product Data Sheet for more detailed information about each of these adhesives.

Usage

Sika® CarboShear L profiles are 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 service ability 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

Advantages

• 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.

Packaging
