Flat component, shear force reinforcing element, and reinforced concrete/prestressed concrete component with a shear force reinforcement of such shear force reinforcing elements

A shear force reinforcing element (Q) for a reinforced or prestressed concrete component, comprising:

• a flat component of metal configured to provide a shear force reinforcing element (Q) and suitable for mounting a stirrup (30) thereto, comprising a lower section, configured for connection with a lower longitudinal reinforcement of a reinforced or prestressed concrete component, wherein the flat component has an angled longitudinal recess (23) ending in a fastening region (BF) and having a feed channel (S) connected thereto and opening to a vertical side edge or an upper horizontal edge of the flat component, wherein the feed channel has a feed angle ζ of between 10° to 120° to the horizontal and the fastening region (BF) is either horizontal or slightly inclined upwards as it extends away from the feed channel and toward a vertical centerline (M) of the flat component;
• and
• at least one stirrup (30) fastened to the flat component.

A reinforced or prestressed concrete component with an upper and a lower longitudinal reinforcement, comprising:

• at least one shear force reinforcing element (Q) with a flat component of metal configured to provide a shear force reinforcing element (Q) and suitable for mounting a stirrup (30) thereto, comprising a lower section, configured for connection with a lower longitudinal reinforcement of a reinforced or prestressed concrete component, wherein the flat component has an angled longitudinal recess (23) ending in a fastening region (BF) and having a feed channel (S) connected thereto and opening to a vertical side edge or an upper horizontal edge of the flat component, wherein the feed channel has a feed angle ζ of between 10° to 120° to the horizontal and the fastening region (BF) is either horizontal or slightly inclined upwards as it extends away from the feed channel and toward a vertical centerline (M) of the flat component;
• and
• and at least one stirrup (30) connected to the flat component, whereby the at least one stirrup (30) of the at least one shear force reinforcing element (Q) has a connection to the upper longitudinal reinforcement of the reinforced or prestressed concrete component and the flat component has a connection to the lower longitudinal reinforcement of the reinforced or prestressed concrete component.
