Abstract
A self-raising form control system and method is provided that that may be used to form elevator shafts and other vertical building structures. The apparatus includes one or more form elements for defining an area to receive a formable material, such as concrete. Each element is attached to the form structure. A lift apparatus is provided for lifting the form elements. The lift apparatus comprises a measurement device for measuring the position of said lift apparatus relative to a fixed point. The lift apparatus is connected to the form structure. A control unit is provided for controlling the lift apparatus. The control unit is signal connected to the measurement device and is signal connected to the lift apparatus.
Claims20
A controlled method of raising a form, comprising the steps of:
- providing a plurality of jacks supporting m-a form structure;
- providing a plurality of lift position sensors corresponding to the plurality of jacks;
- supporting said jacks on a wall by anchoring the jacks to the wall;
- lifting said form structure with said plurality of jacks anchored to said wall;
- monitoring a lift position of each said jack with the lift position sensor corresponding to each said jack;
- and pausing one or more jacks while one or more lift position sensors corresponding to said one or more jacks reports a position value that is outside of a deviation tolerance range.
A controlled method of raising a form, comprising the steps of:
- providing a plurality of jacks connected to a form structure;
- supporting the weight of the form structure by attaching said jacks to a wall;
- lifting said form structure with said plurality of jacks attached to said wall;
- monitoring a lift position of said jack with a lift position sensor corresponding to each said jack;
- and
- pausing one or more jacks during times when one or more lift position sensors corresponding to said one or more jacks reports a position value that is outside of a deviation tolerance range.
