Abstract: A tile holding device for presetting tiles comprises strip-shaped core members attachable to the inner surface of a form panel as arranged in parallel at a required spacing, long joint members made of elastic material and each mountable on the core member, and short joint members made of elastic material and to be arranged between and joined to each two adjacent long joint members. Preferably, the long joint member comprises a mounting portion in the form of an outwardly open channel, an inward projection projecting inward from the center of width of the mounting portion and having a specified height for forming a long joint, and a side projection projecting sidewise from each side of the inner end of the inward projection for engaging tiles.
