1. A spacer structure for a sandwich construction, comprising:
a material web which is provided with a plurality of cuts and has a material web plane as a first plane, wherein a plurality of bearing surfaces, which are spaced apart from the first plane and are disposed in a second plane, are formed in portions by a forming process of the material web, wherein spacing elements in a transition region between the first plane to the second plane run in each case along a direction of extent from the first plane into the second plane, the spacing elements thus spacing apart the first plane from the bearing surfaces,
wherein:
by the forming process of the material web, which is carried out by bending the bearing surfaces out of the first plane, the bearing surfaces are twisted in relation to the first plane, on the one hand, and the spacing elements are distorted due to twisting about the direction of extent, on the other hand.
