<p>An apparatus for forming a building support structure includes opposing, inward-facing concrete forms (114, 116) arranged adjacent to one another and in a closed-perimeter formation. Each inward-facing concrete form has an associated truss module (118, 120). The apparatus includes actuator devices (196, 198) which are mounted on selected truss modules. The actuator devices can move the inward-facing concrete forms translationally with respect to the respective truss module. An insert concrete form is arranged in a closed-perimeter shape and can be located within the closed-perimeter formation of the inward-facing concrete forms. A yoke system (106) connects selected truss modules to the insert concrete form. Climbing devices (108) are attached to the yoke system and can engage associated climb rods to thus move the apparatus along the climb rods.</p> |
