1. floor board block that is used to be provided with the floor, described floor board block is laminate floorboards (1), thickness with 0.5cm to 1.5cm, described floor board block (1) is a rectangle, it is elongated or square, and described floor board block have first and second pairs relative limit (2-3,26-27), the core (8), decorative layer (55) and the bottom (58) that constitute by MDF/HDF;

  • Wherein the edge at least the first pair of relative limit (2-3) locates to be provided with basically that form is the coupling part (4-5 of tongue (9-31) and groove (10-32);

    28-29), described groove (10-32) is defined by top projection (22-42) and bottom projection (23-43), thus these coupling parts (4-5;

    28-29) allow two such floor board block (1) to interconnect, it is characterized in that, on described first pair limit, floor board block (1) has following at least supplementary features;

    -coupling part (4-5;

    28-29) be provided with whole mechanical locking (6), the floor board block (1) that prevents two connections is along separating with the direction on the base (7) that is parallel to the floor board block (1) after being connected perpendicular to relevant limit (2-3);

    -coupling part (4-5;

    28-29) be provided at immobile interlocking on all directions in the plane vertical with relevant edge;

    -coupling part (4-5;

    28-29) make one with core (8) with whole mechanical locking (6);

    -bottom projection (23;

         43) stretch out top projection (22;

         42) in addition;

    -locking device (6) is at least by being positioned at bottom projection (23;

         43) stretch out top projection (22;

         42) part in addition constitutes;

    -coupling part (4-5) and locking device (6) allow two such floor board block (1) can pass through rotational engagement;

    And on described second opposite side (26-27), floor board block (1) has following at least feature;

    -coupling part (4-5;

    28-29) be provided with locking device (6;

         30), this locking device is different with the locking device on the coupling part of floor board block (1) first opposite side (2-3);

    -coupling part (4-5;

    28-29) and locking device (6) allow by moving two such floor board block engagement and interlocking, these coupling parts (4-5 thus;

    28-29) mate mutually by the connection that is interlocked.
