This standard provides guidelines for the selection, sizing, and installation of fixing devices such as expansion plugs, anchor bolts, and wooden plugs in solid construction materials like walls, ceilings, and floors. It outlines the preparation of holes, embedment techniques, and safety factors to ensure secure attachment of structural and architectural fixtures.
Code of practice for use of fixing devices in walls, ceilings and floors of solid construction
Quick Reference Values
typical factor of safety static loads4
typical factor of safety vibratory loads10
minimum hole depth clearance5 mm greater than plug length
minimum edge distance5 times drill diameter
Practical Notes
Ensure the drilled hole diameter strictly matches the anchor manufacturer or code recommendations to prevent loss of pull-out strength.
Avoid using traditional wooden plugs in damp environments or exposed external walls due to the risk of moisture expansion, decay, and subsequent loss of grip.
When installing expansion anchors near the edge of a concrete or masonry member, strictly maintain minimum edge distances to avoid substrate cracking or edge breakout.
