System Components and Construction Sequence
Components of the conventional wall system are similar to conventional wood system components for slabs but have different names. Joists become studs and stringers become wales. Also, the two systems are similar in that they are built in situ and stripped piece by piece.
Erection sequence for all wood conventional wood system is as follows:
1. Erection of wall form starts by attaching the first side of the plywood to the concrete footing wood sill (shoe) by anchors or hardened nails. The plywood is erected with the longer direction parallel to the length of the wall.
Studs are then erected and temporarily supported by wood bracing [usually 1 x 6 in. (25.4 x 152.4 mm) brace]. Reinforcing steel, opening boxouts, and other electrical or mechanical systems are installed before the second side of the wall is erected. The plywood is then nailed to the studs and the other wall side (plywood) is then erected.
3. Tie holes are then drilled from both sides of the wall at proper locations.
4. Wales are then erected and attached to the outside of the studs by nails. In double-wale systems, each wale should be located above and below the tie location.
5. Bracing is then installed to support horizontal loads resulting from wind loads and concrete vibration.
6. To facilitate concrete placement and finishing, scaffolds are erected and attached to the top of the wall.
