Abstract (en)
[origin: EP2402531A2] The staircase has a rack on which a step element (1) is arranged, where the element comprises a step and a counter step. The rack and the step element define a linear and continuous cavity for receiving reinforcement (5). The rack is formed as a simple individual element (3) and a double individual element (4), where each individual element is provided with an outer lateral part and an inner lateral part connected with each other by a lower part. The outer lateral part of the element is shaped to receive the step and the counter step. An independent claim is also included for a method for manufacturing a precast concrete staircase.
