A corner anchor is a right-angled metal anchor or bracket that connects two building parts meeting at an angle and so stiffens the corner. It ensures that the parts do not spread apart and that the structure keeps its shape.
Forms and applications
The term corner anchor occurs in several building parts:
- Masonry — a corner anchor ties two walls meeting at right angles, or connects a facade to the floor or joist layer, so the corner does not split open
- Timber and carpentry — a galvanised or stainless angle bracket strengthens the joint between two beams, studs or frame members
- Window frames — corner anchors keep the frame square and anchor it in the reveal of the opening
Function
A corner is often the weakest point in a structure: forces from two directions meet here. The corner anchor takes up tension and shear forces and holds the parts in place. In masonry it works together with other wall anchors to tie the facade to the structure behind.
Points of attention
- Corrosion protection — use galvanised or stainless steel, especially in damp environments
- Correct fixing — screws, nails or anchors suited to the substrate
- Sufficient number — spread over the height of the joint
