Guide to building Solid Sole and Split Sole Raker Shores with clear steps for measurements, bracing, and securing structures.

Solid Sole Raker Shore

Steps:

• Measure and Prepare Materials
  • Measure the height to the insertion point (where the shore will support the wall).
  • Cut the wall plate and sole plate (both 4×4 lumber) to size.
  • Temporarily fix the plates together at a right angle.

• Attach Gusset Plates
  • Attach gusset plates to both sides using 13 nails (65 mm).
  • Leave a gap of 1–1.5 cm between the edge of the gusset plate and the lumber.

• Construct the Raker
  • Create the raker at a 45° or 60° angle.
    • For 45°, attach a 60 cm cleat to the wall plate using 13 nails.
    • For 60°, attach a 75 cm cleat to the wall plate using 20 nails.
  • Secure the top of the raker to the wall plate with gusset plates on both sides, using 13 nails (65 mm).
  • Attach gusset plates to the lower end of the raker (both sides) with 5 nails, without nailing to the sole plate yet.

• Set Up the Raker
  • Place the raker against the structure. If the raker exceeds 3.3 m in length, attach midpoint braces (2×6 lumber) with 5 nails (90 mm) on both sides.
  • Leave a 3 cm gap at the lower end and attach a 60 cm cleat to the sole plate using 14 nails (90 mm). Insert a wedge.

• Anchor the Sole Plate
  • Install a 4×4 sole plate anchor and drive stakes (pickets) into the ground:
    • 2 stakes for paved surfaces.
    • 4 stakes for soil.
  • Insert a wedge between the sole plate and the anchor and tighten it securely. Tighten the wedge at the raker’s base as well.

• Repeat for Additional Rakers
  • Create and position a second raker. Maintain a maximum spacing of 2.4 m between rakers.

• Add Bracing
  • If the insertion point exceeds 2.4 m, add horizontal bracing at the top, middle, and bottom.
  • Install X-bracing between rakers for added stability.

• Finalize
  • Tighten all wedges at the base.
  • Nail gusset plates to the lower part of the raker and secure midpoint braces to the raker.

Split Sole Raker Shore

Steps:

• Measure and Cut Materials
  • Measure the height to the insertion point and determine its location.
  • Cut the wall plate (4×4 lumber) to size.
• Construct the Raker
  • Decide on a 45° or 60° angle:
    • For 45°, attach a 60 cm cleat with 13 nails.
    • For 60°, attach a 75 cm cleat with 20 nails.
  • Secure gusset plates to both sides of the cleat and raker with 13 nails each.

• Prepare the Base
  • U-shaped base: Use for 45° rakers on soil.
  • Trough base: Use for 45° or 60° rakers on paved surfaces (e.g., asphalt).
  • Steps to Create the Base:
    1. Cut a 4×4 piece to 45 cm. Attach gusset plates to both sides with 8 nails (65 mm).
    2. Insert the raker’s lower end into the base, and tighten a wedge. Nail both sides of the raker to the gusset plates using 5 nails each (65 mm).
    3. Create two sets of bases.

• Install Braces
  • Measure from the wall plate to the raker.
  • Cut and attach bottom braces and midpoint braces (2×6 lumber) with 5 nails (90 mm) on both sides.
  • Attach the bottom brace 30 cm above the base of the wall plate.

• Final Assembly
  • Position the second raker. Insert wedges at the base and tighten.
  • Secure all gusset plates with 5 nails (90 mm) each.

Additional Notes:

• Solid Sole Raker Shore: Suitable for construction sites and disaster response to support walls or structures.
• Split Sole Raker Shore: Flexible for various ground conditions (e.g., soil or asphalt).

This guide ensures proper support for walls and structures in emergency or construction scenarios.
