Fischer FHB II-PF 20 x 170 Hex Bolt Anchor

1. Pengenalan

The Fischer FHB II-PF 20 x 170 is a high-performance hex bolt anchor system designed for secure and reliable fastening in both uncracked and cracked concrete. This system utilizes a specialized mortar cartridge containing a styrene-free vinylester mortar that cures rapidly, ensuring efficient installation and high load-bearing capacity. It is compatible with Fischer highbond Anchor FHB II-A S (standard) and FHB II-A L (long) anchor rods, available in galvanized steel, stainless steel, or highly corrosion-resistant steel. The FHB II-PF system is engineered for demanding applications such as securing facades, machinery, and steel constructions in various indoor and outdoor environments.

2. Maklumat Keselamatan

Always adhere to local safety regulations and guidelines when working with power tools and anchoring systems. Failure to do so may result in injury or damage.

• Pakai peralatan pelindung diri (PPE) yang sesuai, termasuk cermin mata keselamatan, sarung tangan, dan pelindung pendengaran.
• Ensure the work area is well-ventilated, especially when handling mortar cartridges.
• Verify the structural integrity of the concrete substrate before drilling and installation.
• Do not exceed the specified load capacities for the anchor system.
• Jauhkan kanak-kanak dan kakitangan yang tidak dibenarkan dari kawasan kerja.
• Dispose of used materials and packaging responsibly.

3. Kandungan Pakej

Verify that all components are present and undamaged before beginning installation. The package typically includes:

• Fischer FHB II-PF 20 x 170 Hex Bolt Anchor Rods
• Fischer Mortar Cartridges (quantity as per order)
• Hex Nuts and Washers
• Instruction Leaflet (this document)

4. Arahan Pemasangan

Follow these steps carefully for proper installation and optimal performance of the Fischer FHB II-PF anchor system.

1. Prepare the Borehole: Drill a hole into the concrete substrate using a rotary hammer and a drill bit of the specified diameter (e.g., 20mm for M20 anchors) and depth. Ensure the hole is clean and free of dust and debris. Proper hole cleaning is crucial for bond strength.
2. Insert Mortar Cartridge: Carefully insert the Fischer mortar cartridge into the prepared borehole. The cartridge contains a styrene-free vinylester mortar designed for rapid curing and high performance.
3. Masukkan Rod Sauh: Attach the Fischer highbond Anchor Rod (FHB II-A S or FHB II-A L) to the appropriate setting tool (e.g., SDS rotary hammer). Drive the anchor rod into the mortar cartridge. During this setting process, the rotation and impact of the tool destroy the cartridge, thoroughly mixing and activating the mortar mass within the borehole.
4. Allow Curing: The mortar cures very quickly. Refer to the product's technical data sheet for specific curing times based on ambient temperature. Do not apply load until the mortar has fully cured.
5. Tighten Hex Nut: Once the mortar has fully cured, apply the specified torque to the hex nut using a torque wrench. This action tensions the cones of the anchor rod, pressing them firmly against the cured mortar within the borehole, creating a secure, load-bearing connection.

Note: The Fischer FHB II-PF system offers super fast curing, reducing wait times, especially for series installations. It provides high load values in cracked concrete, potentially requiring fewer attachment points.

5. Arahan Operasi

Once installed and cured, the Fischer FHB II-PF anchor is ready to bear the intended load. Ensure that the applied load does not exceed the anchor's certified capacity for the specific concrete type and installation conditions. Regularly inspect the anchor and the attached fixture for any signs of loosening, corrosion, or damage, especially in dynamic load applications or harsh environments.

6. Penyelenggaraan

The Fischer FHB II-PF anchor system is designed for long-term durability with minimal maintenance. However, periodic checks are recommended:

• Pemeriksaan Visual: Periodically inspect the anchor and the surrounding concrete for any visible cracks, corrosion, or signs of movement.
• Pemeriksaan Tork: If the application involves vibrations or dynamic loads, consider periodic torque checks on the hex nut to ensure it remains at the specified setting.
• Faktor Persekitaran: In corrosive environments, ensure that the anchor material (e.g., highly corrosion-resistant steel) is appropriate for the conditions and monitor for signs of degradation.

7. Penyelesaian masalah

Jika anda menghadapi masalah semasa atau selepas pemasangan, pertimbangkan perkara berikut:

• Anchor Not Holding:
  • Ensure the borehole was cleaned thoroughly. Dust and debris can significantly reduce bond strength.
  • Verify the correct drill bit diameter and hole depth were used.
  • Check if the mortar had sufficient curing time before applying load.
  • Confirm the anchor rod was properly inserted, mixing the mortar.
• Difficulty Inserting Anchor Rod:
  • Check for obstructions in the borehole.
  • Ensure the drill bit was not worn, leading to an undersized hole.
• Anchor Corrosion:
  • Ensure the correct anchor material (galvanized, stainless, or highly corrosion-resistant steel) was selected for the environmental conditions.
  • If corrosion is observed, consult a structural engineer for assessment and potential replacement.
