Column Assembly Sketch FOOTING NOTES:

  1. Concrete strength shall be a minimum of 20 Mpa (3000 psi) at 28 days.
  2. Concrete shall be Type 10 or Type 50 with a max 20 mm (3/4") aggregate and 3" slump.
  3. Rebar shall be grade 400.
  4. Rebar is to be tied at all intersections.
  5. Column shall be placed in the center of the footing. Eccentric loading reduces the footing capacity.
STEMCO Column Assembly
  1. Support and brace the beam in its intended postion using lumber.
  2. Measure the distance from the top of footing to the underside of the beam and write down this number.
  3. IMPORTANT Position the threaded rod in the support head at the midpoint of its extension to allow for future up or down adjustment.
  4. Measure the length of your original column from the bottom of the baseplate to the top of the head/top plate assembly.
  5. Subtract Step 2 and Step 4 measurements and record number.
  6. Remove head and trim top of column by the value calculated in Step 5 using an approved metal cutting blade. The cut must be level, true and free of nicks or burrs.
  7. Centre the assembled column under the beam and centre on the footing. Plumb column in both directions.
  8. Drill 3/16" x 2.5" holes into the wood beam through holes in the top plate and install 1/4" x 3" lag bolts.
  9. Column bases shall be encased by a floor slab or equivalently secured as specified by others.
NOTE: As required by C.S.A. 086, and TrusJoist, all beams shall have adequate attachment and positioning of lateral bracing to achieve member stability (as determined by the building designer).
