Abstract (en)

[origin: EP0947257A2] To form basket structures (3,4) of reinforcement wire rods (5), they are aligned parallel to the concrete pipe axis and are assembled on a frame (9). The frame has a fixed perforated frame (13) in the longitudinal direction, and a sliding holding frame (18). Straight or angled lateral rod sections or kinked bars are welded to the longitudinal wire rods as required, using a mobile fitting unit traveling at right angles to the longitudinal wire sections, to place them according to the wire thickness and intervals. The frame (9) is on a turntable (10), for rotation round its vertical axis, between two welding units for the fittings. The fittings are aligned during welding. The finished reinforcement basket structures are taken by a crane (19-25) and fitted into each other.
