Abstract
A formwork system includes (a) a wallform panel for forming a wall portion; and (b) at least one brace assembly including a pair of vertically spaced apart props pivotably connected to the wallform panel for pivoting of the brace assembly relative to the wallform panel between a storage position, in which the brace assembly lies adjacent the wallform panel, and a deployed position, in which the brace assembly projects from the wallform panel for anchoring the props to a ground surface through a common base plate connected to each prop.
Claims19
A formwork system, comprising:
- a) a wallform panel having a first side for forming a concrete wall portion and a second side opposite the first side;
- b) at least one brace assembly mounted to the second side of the wallform panel for supporting and aligning the wallform panel, the brace assembly including:
- i) a base plate for anchoring to a ground surface spaced horizontally apart from the wallform panel,
- ii) a pair of vertically spaced apart swivel connectors pivotably mounted to the second side of the wallform panel for pivoting about a vertical axis relative to the wallform panel, and
- iii) a pair of vertically spaced apart props, each prop having an adjustable length between a first end and a second end, the first end of each prop pivotably connected to the base plate and the second end of each prop pivotably connected to a corresponding swivel connector, and the props fixed to pivot with the swivel connectors about the vertical axis for swinging the brace assembly between a deployed position, in which the brace assembly projects from the wallform panel for anchoring the base plate and supporting the wallform panel upright, and a storage position, in which the brace assembly lies adjacent the wallform panel.
A brace assembly for supporting and aligning a wallform panel, comprising:
- c) a base plate for anchoring to a ground surface spaced horizontally apart from the wallform panel;
- d) a pair of vertically spaced apart swivel connectors pivotably connectable to the wallform panel for pivoting about a vertical axis relative to the wallform panel;
- and
- c) a pair of vertically spaced apart props, each prop extending between a first end connected to the base plate and a second end connected to a corresponding swivel connector, the props fixed to pivot with the swivel connectors about the vertical axis for swinging the brace assembly between a deployed position, in which the brace assembly projects from the wallform panel, and a storage position, in which the brace assembly lies adjacent the wallform panel, wherein at least one of the props has an adjustable length between the first and second ends.
A method of operating a formwork system, comprising:
- a) positioning the formwork system upright, the formwork system comprising a wallform panel and a brace assembly pivotably connected to the wallform panel, the brace assembly including a pair of vertically spaced apart props, each prop having a first end pivotably connected to the wallform panel and a second end connected to a base plate of the brace assembly;
- b) swinging the brace assembly relative to the wallform panel from a storage position to a deployed position;
- c) when the brace assembly is in the deployed position, anchoring the base plate to a ground surface spaced apart from the wallform panel;
- d) after (c), adjusting a length of at least one of the props to align the wallform panel;
- e) after (d), unanchoring the base plate from the ground surface;
- f) after (e), swinging the brace assembly from the deployed position back to the storage position.
