Claims10
A method for constructing a structure:
- providing a foundation including a plurality of hydraulic cylinders;
- providing a truss tower located on the foundation and configured to support a tower built on the foundation;
- extending the plurality of hydraulic cylinders to lift the tower;
- retracting a subset of the plurality of hydraulic cylinders to create a first opening;
- inserting a first block of a next level into the opening;
- retracting a rest of the plurality of hydraulic cylinders to create a second opening;
- inserting a second block of the next level into the second opening;
- and
- extending all of the plurality of hydraulic cylinders to lift the tower including the next level by directly exerting a vertical force on a bottom surface of the next level of the tower such that the tower moves with respect to the truss tower.
