Overview

• Part of the Connector Training for Contractor Series.
• Focus on basic installation techniques for various types of construction connectors including mudsill anchors.

Key Concepts

Mudsill Anchor Terms

• Mudsill Anchors: Connectors or bolts that attach the sill plate of a framed wall section to its foundation.
• Sill Plate: Bottom horizontal framing member attached to the foundation; typically made of 2-by or 3-by treated lumber.
• Stem Wall: Narrow wall foundation usually 4-8 inches wide, made of concrete or masonry block.
• Grout: Concrete fill poured into blocks; important for anchor consolidation.
• Slab on Grade: Type of foundation where a concrete floor is placed directly on soil.
• Forms: Structures to shape and hold concrete until it cures; can be permanent or temporary.
• Brick Ledge: Foundation wall where brick or veneer rests.

Installation Overview

• Use the correct mudsill anchor specified by the engineer or designer.
• Inappropriate anchor choice can lead to inspection problems or job shutdown.
• Various anchors are available for different foundation types (e.g., block or concrete).

Installation Techniques

General Tips

• Ensure mudsill anchor does not move or sink into concrete/grout while it is wet.
• Some anchors allow for alternate installations; consult the framer before proceeding.

Specific Installations

MAS (Concrete Applications)

• Can be installed before or after concrete is poured.
• Straps should be outside the concrete; embedded portion fully submerged.
• Use nails to secure straps; avoid short nails that could loosen the anchor.

MASB (Block Installations)

• Installed after grout is poured.
• Straps placed on the top outside edge of the block.
• Wiggle anchor to ensure grout consolidation.

LMA (Concrete Stem Walls)

• LMA4 for 2x4 plates, LMA6 for 2x6 plates.
• Installed after concrete poured; ensure tabs are submerged.

MAB (Concrete/Block)

• Two types: MAB 15 (7-inch embedment), MAB 23 (15-inch embedment).
• Position depends on sill plate size; ensure sufficient concrete between straps.
• Do not separate straps more than 90°.
