Construction drawing for a reinforced concrete staircase, including a structural step section and a geometric layout for a winding flight. The sectional detail specifies a 2.5 cm concrete cover, ribbed steel reinforcement (acero aletado), and finishes comprising smooth ceramic tiles with non-slip nosing. Standard dimensions show a 0.175 m riser height and 0.28 m tread width.
The plan view details the geometry for the first flight of eight risers designed to reach a 1.45 m landing. It includes calculations for the line of travel and specific widths for winding steps measured from the stringer line. Detailed labels cover material specifications for concrete tension and adhesive application for ceramic finishes (detalle escalera hormigon armado).
