Formwork apparatus for construction of stairs
A formwork apparatus (30) has a left side extender arm (32) and a right side extender arm (34), each of which are slidably connected to a bridging connector (36) which spans the extender arms so as to form an adjustable waler structure (35). There is also a left end anchor plate (38) and a right end anchor plate (40) which are connected to opposite ends of the adjustable waler structure. The anchor plate (38) is adjustably connected to the left end of the left side extender arm, and the anchor plate (40) is adjustably connected to the right end of the right side extender arm. The extender arms can be engaged against a riser board (57) cut to an appropriate length and height for each step of the stairs being constructed. The anchor plates can be engaged against upright surfaces which are either vertical or not vertical at opposite sides of the stairs being constructed.
