Types of Concrete Anchors
Different anchor types for different applications: 1. Wedge Anchors: - Full expansion against concrete - Highest load capacity - Not removable - Use: Structural connections 2. Sleeve Anchors: - Multi-piece expansion - Good for hollow masonry - Moderate load capacity - Use: General purpose 3. Drop-in Anchors: - Internally threaded - Flush mount installation - Requires setting tool - Use: Repetitive attachments 4. Strike Anchors: - Nail-style installation - Quick installation - Light-duty only - Use: Temporary installations
Anchor Selection Criteria
Key factors for anchor selection: 1. Load Requirements: - Determine design load (tension and shear) - Check anchor load tables - Apply safety factors 2. Base Material: - Solid concrete: All anchor types work - Hollow masonry: Sleeve anchors - Cracked concrete: Use ICC-approved anchors 3. Installation Type: - Fixed object: Wedge or sleeve anchor - Temporary: Strike anchor - Repetitive: Drop-in anchor 4. Environment: - Dry interior: Carbon steel - Exterior: Hot-dip galvanized - Corrosive: Stainless steel
Installation Best Practices
Proper installation ensures anchor performance: 1. Hole Preparation: - Drill to correct diameter - Drill depth = anchor depth + 1/4" - Clean hole thoroughly (blow and brush) 2. Installation: - Wedge anchor: Hammer in, tighten nut - Sleeve anchor: Insert and tighten - Drop-in: Set with setting tool 3. Minimum Spacing: - 10 x diameter from edges - 12 x diameter between anchors - From cracks: 6 x diameter minimum 4. Edge Distance: - Maintain minimum edge distance - Reduces splitting risk - Ensures full load capacity
