Abstract: Stackable wall spacer adapted for automated distribution using a feeder device and adapted to support a reinforcement grid, where the wall spacer comprises a plurality of leg sections each having a lower foot adapted to be placed on a mold surface for the concrete, where a plurality of wall spacers can be stacked in each other with the feet of one wall spacer extending into corresponding voids of a subsequent wall spacer, where the side wall of a leg section is parallel with the side wall of a leg section of a subsequent wall spacer. The advantage of the invention is that the wall spacers can be stacked in a space saving manner in each other, which allows a cost-efficient storage and transportation of wall spacers. The invention further allows for wall spacers that can be distributed by using a hand-held or automatic feeder device. Further, a reinforcement grid can be supported by a wall spacer regardless of the position of the spacer.

Abstract: A stackable foundation spacer is adapted for automated distribution. The foundation spacer includes a lower bearing surface adapted to be placed on a foundation support surface for the concrete, a first support surface adapted to support the reinforcement grid in a plurality of support points, and an outer circumferential side wall connecting the lower bearing surface with the first support surface. The outer circumferential side wall is inclined outwards from the lower bearing surface to the first support surface with an angle ?, and the shape of the first support surface is larger than a mesh in the reinforcement grid that is to be supported. Distribution of foundation spacers can be automated by using a hand-held or automatic feeder device. Further, a reinforcement grid can be supported by a foundation spacer regardless of the position of the spacer.
