1. A base plate, which is made of plastic and is intended for supporting a rail for a rail vehicle on a substrate, the base plate comprising
a lower face, assigned to the substrate, and an upper face on which a supporting surface for the rail is formed, at least one recess, from which a passage leads to the upper face of the base plate, being formed in the lower face of the base plate, the diameter of the recess in a direction transverse to the longitudinal axis of the passage being greater at least in part than the diameter of the passage, so that a stop for a component fitted into the recess is formed on a top surface, adjacent to the upper face of the base plate, of the recess, and a component, an abutment for rotationally secure support of the component is provided on an inner surface surrounding the recess, wherein the component fitted into the recess is an insert piece which is made of a material having a higher strength compared with the plastic material of the base plate and is supported with a counter-bearing, formed on one of its outer surfaces, on the abutment of the recess and with its upper face against the top surface of the recess, and wherein the insert piece comprises a lower face, assigned to the lower face of the base plate, starting from which a recess in which a passage formed into the insert piece and aligned flush with the passage of the base plate opens, the recess of the insert piece being configured for rotationally secure reception and support of a head of a clamping element, a threaded shank of which is fed during use through the passages of the insert piece and of the base plate,
and
at least one shaped element for supporting or guiding at least one component additionally arranged on the base plate is formed on the upper face of the base plate,
wherein a heel is formed onto the upper face of the insert piece, and, wherein, in a region in which the passage of the base plate merges into the top surface of the recess of the base plate, a seat for the heel, which is shaped in accordance with the heel, is formed.
