2. FORMWORK Scaffold frames
Scaffold tubes and frames are used to support formwork. The tubes and frames are used in conjunction with bearers and joists to support the plywood sheets that form the slab, column or beam.
2. Plywood
Plywood (Formply) comes in various thicknesses from 12, 17 and18mm. The sizes of sheets are generally 2440 x 1220 mm others are available.
3. Bearers and Joists
Bearers vary in size but are generally 150 x 100 with joists 100 x 50.
Bearers and joists may be LVL’s in construction for strength.
Sizes for LVL’s are 95 x 65.
These are the horizontal members laid on edge supporting the plywood.

 Studs and wales are used in wall formwork or edge beam construction.
Studs are the vertical members and wale the horizontal.
5. Starter bars
Starter bars are the reinforcement bars that are protruding out from previously poured concrete. They help to tie in between joins from column to slab or slab to column.
6. Braces/Props
Braces and props are used to secure formwork columns and walls and to help straighten and align. They are needed to add to the strength and stiffness of the formwork during the pouring of the concrete.

Tube and coupling components are also used to support and brace formwork in some situations where conventional scaffold frames are unworkable.
8. Wall ties
Wall ties are placed at specific points in the formwork walls so as to maintain an even distance between sheets with the use of “he” & “she” bolts or ties.
9. Column clamps
Column clamps are used to tie columns together with the use of wedges and pins.
They are spaced as per column height and dimensions. The column clamps increase in number and decrease in spacing due to the increased pressure the lower down the column.
