Angle Brackets (Junior Cert Wood Technology): Revision Notes

Angle Brackets in Woodworking

Angle brackets are key tools in woodworking. They support and reinforce structures, strengthen joints in corners, and come in different types and materials.

Definitions

• Angle Bracket: A tool used in woodworking to support or strengthen joints, usually at a 90-degree angle.
• L-shaped Bracket: A bracket shaped like an 'L', commonly used for simple corner joints.
• T-shaped Bracket: A bracket shaped like a 'T', used to join three pieces of wood and give extra support.
• Corner Bracket: Designed to secure corners; often decorative too.

Functions of Angle Brackets

Angle brackets stabilise joints, prevent sideways movement, and keep structures firm.

Types of Angle Brackets

• L-shaped Brackets: Used for corner support.
• T-shaped Brackets: Join three pieces and strengthen split beams.
• Corner Brackets: Add a decorative element with function.

T-shaped	Middle sections and supports	Variable	Added support
Corner Brackets	Aesthetic and functional use	Variable	Decorative and reinforcing

Materials Used for Angle Brackets

• Steel:
  • Common for heavy support.
  • Heavy and durable, ideal for high-stress uses.
  • Can rust unless coated.

• Brass:
  • Adds a decorative look.
  • Suitable for light, decorative uses.
  • Not best for heavy loads.
• Aluminium:
  • Light and strong.
  • Great for areas prone to corrosion.

Applications of Angle Brackets

Angle brackets are used in different wood constructions:

• Cabinet frames: Support to maintain shape.
  • Steel in Cabinet Frames: For cabinets holding heavy items.
• Bookshelves: Prevent sagging.
• Decking supports: Prevent plank shifting.
  • Aluminium in Decking Supports: Good for outdoors where corrosion resistance is key.

Tips for Selecting Angle Brackets

Consider these aspects:

• Load Bearing Needs: Determine how much weight is needed.
• Aesthetic Preferences: Match décor if visible.
• Environment: Consider corrosion resistance in damp areas.
