The present invention provides a diagonal strut device (1) for reinforcing arrangement on an underfloor of a motor vehicle, wherein the diagonal strut device (1) comprises a plurality of struts (2) composed of a fibre-reinforced plastic composite material, which struts (2) extend away from a central node element (3). Each strut (2) can be connected by the end of each strut (2) to the underfloor, wherein the end of each strut (2) faces away from the central node element (3). For this purpose a connecting node element (4) is arranged at the end of each strut (2), the end faces away from the central node element (3), wherein the central node element (3) and the connecting node elements (4) are embodied from a lightweight metal material. The central node element (3) and the connecting node elements (4) are connected here to the struts (2) by means of an at least materially joined cast connection. In addition, the present invention relates to a method for manufacturing the diagonal strut device (1) and to the motor vehicle underfloor which uses the diagonal strut device (1) for reinforcement.
