Abstract (en)
For casting a concrete inside corner wall structure, the corner is defined by a corner member (16) to extend lengthwise of the corner with the adjacent edges of a pair of form panels (12) that are disposed generally perpendicular to each other being butted against the outer edges of the corner member (16) and a control unit (10) is interconnected with the form panels (12) and the angle member to retain this relationship between the panels and angle member incident pouring and hardening of the concrete. The control unit (10) has actuator means associated therewith operable to move the panel edges into abutment with the outer edges of the angle member prior to concrete pouring and to strip both the form panels and the angle member from the hardened concrete structure.
