发明名称 Reinforcement cage for pre-fabricated steps and device for producing the same
摘要 <p>The cage has an upper part (2) for an upper support seat (24), a lower part (4) for a lower support seat (38), an upper intermediate part (3), a lower intermediate part (5), and a central part (1). The upper part, the lower part, the intermediate parts and the central part have longitudinal bars (6, 15, 20, 31, 36). Cross bars (12, 18, 19, 22, 23, 34, 35) are connected to the upper part and the lower part, where the longitudinal bars are connected with the central part via the upper intermediate part. An independent claim is also included for a device for manufacturing a reinforcement cage.</p>
