Installing HILTI HVU-TZ Capsule Adhesive Anchors correctly is crucial for ensuring a secure and reliable fastening. Here's a step-by-step guide to help you through the process:
-
Concrete Strength Check: Verify that the concrete you're working with has a minimum compressive strength of 15 N/mm² (2000 psi). This is essential for the anchor to perform as intended.
-
Capsule Inspection: Before you begin, examine the capsules to ensure they are undamaged and within their expiration date. Using faulty capsules can compromise the anchor's performance.
-
Hole Preparation: Thoroughly clean the drilled hole. Use an air jet to remove all drilling dust and any standing water. Contaminants like oil, bitumen, or chemicals can significantly reduce the anchor's load capacity.
-
Threaded Rod Setting: Carefully insert the threaded rod into the capsule. Use a rotary hammering action with a speed between 250 to 1000 r.p.m. Apply moderate pressure and use a setting tool designed for this purpose. Stop the machine once the embedment depth is reached.
-
Adhesive Fill: After setting the rod, check that the annular space is completely filled with adhesive up to the concrete surface. If no adhesive emerges, the anchor fastening may not be properly installed and should not be used.
-
Avoid Disturbance: Do not disturb the anchor or remove any setting tools until the specified curing time has passed. This is vital for the adhesive to set correctly.
-
Final Tightening: After the curing time, use a torque wrench to tighten the anchor to the manufacturer's recommended specifications. Only apply load after the curing time.
Always follow these instructions precisely to ensure the HILTI HVU-TZ Capsule Adhesive Anchors perform safely and reliably. Remember to prioritize safety by adhering to all safety regulations and wearing appropriate protective gear during the installation process.
