the invention relates to a device used as a laying aid for tiling work , comprising a base element having a support region for laying flat on a surface to be covered with tiles , and a tile - supporting region on which tiles are placed . the tile - supporting region has at least two web - like spacer elements which extend perpendicularly with respect to a plane defined by the tile - supporting region and which are arranged at an angle of an integer multiple of 90 ° relative to one another in said plane , and which have a thickness corresponding to a desired joint spacing . to avoid the disadvantages of the known laying aids and to achieve uniform joint spacing and an even surface , whereby the laying aid is intended to be especially easy to handle , the base element is designed as a disk - like element having a base area that is smaller than a base area of the tiles to be laid .
