1. A support device for an electrical energy store for arrangement in a storage housing between at least two storage modules of the electrical energy store and for holding the at least two storage modules, which are fastenable to both sides of the support device in a transverse direction, in the storage housing, comprising:
a beam for fastening to the storage housing, the beam having a bearing face on which holding elements of the storages module are to be placed;
a clamping strip for arrangement on the bearing face of the beam and for clamping the holding elements of the storage modules;
fasteners for fastening the clamping strip to the beam, wherein, in an upper side of the clamping strip, depressions are arranged spaced apart from one another in a longitudinal direction of the support device, which depressions are configured to receive the fasteners, wherein the depressions form continuous channels in the transverse direction; and
an isolation strip which is to be arranged on an upper side of the clamping strip and which is configured to close the channels in order to prevent a thermal event of one storage module from being transmitted to another storage module located opposite in the transverse direction, the isolation strip having two side parts, which extend in the longitudinal direction and cover the depressions at the sides, and cover regions, which cover the depressions on the upper side.
