ABSTRACT:
An apparatus for forming concrete structures includes a first truss module and a second truss module, as well as a first and a second concrete form. The apparatus further includes a first and a second actuator device. Each first and second actuator device is mounted on the respective first and second truss module, and each first and second actuator device can move the respective first and second form translationally with respect to the respective first and second truss module. A yoke connects the first truss module to the second truss module to thereby place the concrete forms in generally parallel, spaced-apart relationship. A climbing device attached to the yoke can engage a climb rod and can move the apparatus upward along the climb rod.
