‌Installation and Usage Guide for FRP I Beam

‌1. Pre-Installation Inspection‌

‌Installation and Usage Guide for FRP I Beam

‌1.1 Material Verification‌

• Confirm that the FRP (Fiber-Reinforced Polymer) I Beam specifications (dimensions, load capacity, and corrosion resistance grade) match the project requirements.
• Check for visible defects (cracks, delamination, or surface irregularities) using ASTM D2584 standards.
• Verify certification documents, including manufacturing date, batch number, and quality compliance (ISO 9001/ASTM standards).

‌1.2 Storage Conditions‌

• Store beams horizontally on wooden supports in a dry, shaded area. Avoid direct sunlight or moisture exposure.
• Maintain a minimum clearance of 50 mm between stacked beams to prevent deformation.

‌2. Pre-Construction Preparation‌

‌2.1 Personnel Requirements‌

• Assign ‌certified engineers‌ with FRP handling experience.
• Provide PPE (Personal Protective Equipment): gloves, safety goggles, and respirators (for cutting/drilling operations).

‌2.2 Tools & Equipment‌

• ‌Essential Tools‌: Non-metallic cutting blades (diamond-coated), FRP-specific adhesives, torque wrenches, nylon slings, and laser levels.
• ‌Prohibited Tools‌: Angle grinders with metallic discs (to avoid fiber contamination).

‌2.3 Site Preparation‌

• Clear debris and level the installation area.
• Mark anchor bolt positions using CAD drawings. Tolerance: ±3 mm.
• Ensure ambient temperature is between 10°C–35°C; humidity <70% for optimal adhesive curing.

‌3. Step-by-Step Installation Procedure‌

‌3.1 Positioning & Alignment‌

• Lift beams using ‌nylon slings‌ (avoid metal chains). Max lifting angle: 30°.
• Align beams with pre-marked anchor points. Use laser levels to ensure ±2° deviation tolerance.

‌3.2 Fixation‌

• ‌Mechanical Fastening‌:
  • Drill holes using carbide-tipped bits (speed: 800–1,200 RPM).
  • Secure beams with ‌316 stainless steel bolts‌ (torque: 25–30 N·m). Apply anti-seize lubricant.
• ‌Adhesive Bonding‌ (for non-load-bearing joints):
  • Clean surfaces with acetone. Apply epoxy resin (e.g., Sikadur 31) in a zigzag pattern.
  • Cure time: 24 hours at 25°C.

‌3.3 Post-Installation Adjustments‌

• Recheck alignment and torque values after 48 hours.
• Trim excess adhesive with non-metallic scrapers.

‌4. Critical Installation Notes‌

• ‌Avoid Impact‌: FRP beams are brittle; never strike with metallic tools.
• ‌Thermal Expansion‌: Account for FRP’s thermal expansion coefficient (18×10⁻⁶/°C) during joint design.
• ‌Electrical Isolation‌: Use insulating washers to prevent galvanic corrosion when connecting to metal structures.
• ‌UV Protection‌: Apply UV-resistant coating if exposed to sunlight (e.g., AkzoNobel Interfine 979).

‌5. Quality Acceptance Criteria‌

‌5.1 Visual Inspection‌

• No cracks, warping, or resin pooling.
• Adhesive coverage ≥95% of bonded areas.

‌5.2 Load Testing‌

• Conduct static load test at 110% of design capacity (per ASTM D790).
• Max deflection: ≤L/250 (L = span length).

‌5.3 Documentation‌

• Submit signed inspection reports, torque logs, and adhesive curing certificates.

6. Maintenance & Long-Term Care‌

‌6.1 Routine Checks‌

• ‌Monthly‌: Inspect for delamination or discoloration.
• ‌Annual‌: Test bolt tension and adhesive integrity.

‌6.2 Cleaning‌

• Wash with pH-neutral detergent and soft brushes. Avoid abrasive materials.

‌6.3 Repair Protocol‌

• ‌Minor Damage‌: Sand affected area and apply repair resin (e.g., West System 105).
• ‌Major Damage‌: Replace the beam segment; do not weld.
