Title: Panel for tiling and engagement piece used for it
Inventor: SHIMA NOBUYOSHI
IPC: E04F13/08
Filed: 1988-03-07
Abstract: PURPOSE:To prevent bond from separating when the joint between tiles is filled with bond by a method in which a plurality of sections are provided on the tiles by forming continuous joint grooves longitudinally and transversely, and the joint grooves between the engagement pieces arranged on the periphery of the sections at a suitable interval are used as the expanded adhering area of the bond. CONSTITUTION:In tiling, a panel 1 is fixed to a cross piece by driving in a nail, and an engagement piece 2 is driven into the position where a transverse joint groove 1a and a longitudinal joint groove 1b are crossed with and fitted into it. Tiles T are stuck to the adjacent two sides of each section of the panel 1 in parallel with an adhesive so as to keep the distance between tiles T at the same distance. Since the diameter of the protrusion 21 of the engagement piece 2 is smaller than the width of a supporting leg 20, when the tile is set in parallel with the protrusion 21, the side edge T1 of the tile T is bulged to the side of the joint grooves 1a, 1b, and its rear surface becomes a fastening part T2. Tiling work is finished by filling the joint between the tiles with bond 3 so that the protrusion 21 is not seen from its outside. Since the bond 3 enters the joint grooves 1a, 1b, the area to be stuck is increased, and since the bond enters the side of the fastening part T2, the detachment of the tile do not occur.
