Abstract
A printing system for printing the lower base of a wind tower or the entire wind tower. The system includes a printing device configured to print the coaxial polymeric shells with an empty volume between the shells. The printing device uses the coaxial polymeric shells as driving rails. A concrete material deposition device configured to deposit the concrete material into the empty volume between the polymeric shells, and a rebar handling device is configured to deliver rebars into the volume between the polymeric shells to reinforce the deposited concrete material.
Claims25
A printing system for printing the lower base of a wind tower, or the entire wind tower, comprising:
- a printing device configured to print first and second polymeric shells and wherein the polymeric shells are coaxial with an empty volume between them;
- a concrete material deposition device configured to deposit the concrete material into the empty volume between the first and second polymeric shells;
- a rebar handling device configured to deliver rebars into the volume between the first and second polymeric shells to reinforce the deposited concrete material;
- a rebar connection and tying device allowing to connect the different rebar elements into a unified construction;
- and
- a driving mechanism that uses the polymeric shells as rails for carrying the printing system weight without transferring weight to the just poured non-dehydrated concrete.
A method of additive manufacturing of the lower base of a wind tower, or the entire wind tower, comprising:
- providing a printing device configured to print the first and second polymeric shells and wherein the polymeric shells are coaxial with an empty volume between them;
- providing a concrete material deposition device configured to deposit the concrete material into the empty volume between the first and second polymeric shells;
- and
- utilizing a rebar handling device configured to deliver rebars into the volume between the first and second polymeric shells to reinforce the deposited concrete material;
- wherein the rebar handling device inserts new rebar edges into conical edges of a previous rebar of a lower layer, and a gripper presses the new rebar to the adjacent rebar of the same layer level.
