  • the rod 27 comprises one or several of:
  • the plastic material comprised in the rod 27 may be present in the form of a polymer or copolymer.
  • the plastic material present in the rod 27 may be present in a plasticized or non-plasticized formulation.
  • the thermoplastic material used can advantageously be applied in the recess 56 with a nozzle (not shown).
  • the rod 27 for example comprises a latent adhesive, preferably a polymer adhesive, adapted for adhering to the connecting tongue in the locked configuration after the latent adhesive has been moistened with water.

  • the rod 27 has a sufficient strength in order not to be removed or to be damaged, when the tongue is pushed into the groove.
  • the rod 27 for example has a substantially uniform thickness E1 in the thickness direction V, preferably comprised between 5% and 40% of the thickness E of the tiles 5.
  • the thickness E1 is larger than the thickness of the recess 56.
  • the rod 27 for example forms a bulge 60 protruding from a mouth of the recess 56, that is to say protruding above the rest of the lower contact surface 54.
  • the thickness E1 is for example comprised between 0.3mm and 1.5mm, preferably between 0.6mm and 0.8mm.
  • the first tile 15 and the third tile 115 are first connected to each other in the connection direction C2.
  • the connecting tongue 134 of the fourth edge 128 of the third tile 115 is introduced, advantageously without much effort, in the connecting groove 130 of the third edge 126 of the first tile 15. This is symbolized in Figure 3 by a sticker 1.
  • first tile 15 and the second tile 20 are put in the locked configuration by introducing the connecting tongue 34 of the second tile into the connecting groove 30 of the first tile (sticker 2).

  • the rod 27 provides a latching action on the connecting tongue 34 (or on the connecting groove 30 in embodiments wherein the rod is fixed on the connecting tongue 34).
  • the rod 27 acts as a locking element when the tiles 15, 20 are joined.
  • the step of putting the first tile 15 and the second tile 20 in the locked configuration comprises angling the second tile with respect to the first tile, and inserting the connecting tongue 34 in the connecting groove 30 in a connection direction C1 forming an angle ⁇ with the thickness direction V around the longitudinal direction L.
  • This substep is symbolized with an arrow F1 in the Figure.
  • the step also includes a substep of pivoting (arrow F2 in the Figure) the second tile 20 with respect to the first tile 15 around the longitudinal direction L, and further inserting the connecting tongue 34 in the connecting groove 30 (arrow F3) until the locked configuration is reached.

  • the fourth tile 120 is also connected to the third tile 115 by introducing the connecting tongue 34 of the fourth tile into the connecting groove 30 of the third tile 115 (sticker 3') in a similar manner as the second tile 20 is connected to the first tile 15.
  • the fourth tile 120 can be moved with respect to the second tile 20 during the connection of the fourth tile to the third tile 115, which makes this connection very easy to perform.
  • the connecting tongue 34 of the fourth tile 120 is introduced into the connecting groove 30 of the third tile 115 (sticker 3')
  • the connecting tongue 134 of the fourth tile 120 may slide (sticker 3") in the connecting groove 130 of the second tile 20 along the third edge 126 of the second tile. This also allows repositioning the fourth tile 120 with respect to the second tile 20 when connecting the fourth tile to the third tile 115.
  • these tiles may be connected in such a way that the first tile 15 and the third tile 115 are offset with respect to the second tile 20 and the fourth tile 120 in the longitudinal direction L. This prevents the third tile 115 and the fourth tile 120 from sliding with respect to the first tile 15 and the second tile 20 along the transverse direction T once in the locked configuration.
  • the other tiles 5 (not shown) are connected to each other in the same manner, using connecting tongues and grooves.
  • the connecting tongue 34 can be inserted in the connecting groove 30 with a reasonable insertion effort, despite the rigidity of the core layers 22. Then, in the locked configuration, the rod 27 acts as an efficient latching element.
  • the set 1 is easy to use, while remaining simple to produce, and cost effective.
  • the rod 27 is applied in the recess 56 during production of the tiles 5 in a simple and durable way.
  • the tiles 5 are adapted for having a weaker connection between the third edged 126 and the fourth edge 128, the set 1 is even easier to use.

    wobei die erste Fliese (15) und die zweite Fliese (20) so beschaffen sind, dass sie in die verriegelte Konfiguration gebracht werden können durch:
    - Abwinkeln der zweiten Fliese (20) in Bezug auf die erste Fliese (15) und Einsetzen der Verbindungszunge (34) in die Verbindungsnut (30) in einer Verbindungsrichtung (C1), die einen Winkel (a) mit der Dickenrichtung (V) um die Längsrichtung (L) bildet, wobei der Winkel (a) zwischen 15° und 70° liegt, und
    - Schwenken der zweiten Fliese (20) gegenüber der ersten Fliese (15) um die Längsrichtung (L) und weiteres Einschieben der Verbindungszunge (34) in die Verbindungsnut (30), bis die verriegelte Konfiguration erreicht ist, dadurch gekennzeichnet, dass
    die erste Fliese (15) frei von einem Stab ist, der sich in einer in der Verbindungsnut (130) im dritten Rand (126) ausgebildeten Aussparung befindet, und die zweite Fliese (20) frei von einem Stab ist, der sich in einer in der Verbindungszunge (134) im vierten Rand (128) ausgebildeten Aussparung befindet, so dass
    eine Verriegelungsstärke zwischen dem dritten Rand (126) der ersten Fliese (15) und dem vierten Rand (128) der zweiten Fliese (20) in der verriegelten Konfiguration geringer ist als eine Verriegelungsstärke zwischen dem ersten Rand (26) der ersten Fliese (15) und dem zweiten Rand (28) der zweiten Fliese (20) in der verriegelten Konfiguration, wobei die Verriegelungsstärke ein Aufwand zum Entriegeln der ersten Fliese (15) und der zweiten Fliese (20) pro Meter der miteinander verriegelten Ränder ist, wenn die erste Fliese (15) und die zweite Fliese (20) parallel zueinander sind.
  2. Satz (1) nach Anspruch 1, wobei der Stab (27) ein Kunststoffmaterial umfasst.
  3. Satz (1) nach Anspruch 1 oder 2, wobei der Stab (27) Folgendes umfasst:

    - Bereitstellen eines Satzes (1) von Fliesen nach einem der Ansprüche 1 bis 11, und
