Floor panels provided with a mechanical locking system comprising a locking strip (5) projecting from a first edge (3) of a first floor panel (1), the locking strip (5) being provided with a locking element (6) formed therefor with a locking groove (7) on a lower side (18) of a second edge (4) of a second bottom plate (2) for locking the first edge (3) and the second edge (4) to cooperate in the horizontal direction, the first edge (3 ) and the second edge (4) are adapted to be mounted by a vertical downward movement of the second edge (4) towards the first edge (3), characterized in that the second edge (4) is connected to the locking groove (7) ) is provided adjacent Kalibriernut (11).
The present disclosure relates to floor panels provided with a mechanical locking system.
Due to the permissible tolerances during manufacture, the thickness of the various floor panels may differ slightly. Thus, various parts of a mechanical locking system may be located at different heights of the floor panels. For example, the distance from the underbody on which the bottom plates are arranged to a spring disposed on a first bottom plate may be from the distance from the bottom to the tongue of a second bottom plate into which the spring is inserted for locking in the vertical direction should be different, as in 1 is shown. This can lead to difficulties in connecting the floor panels, since the floor panels can not come into a locking position. However, such differences in the thickness of the floorboards usually do not cause problems in locking the floorboards together when the floorboards are placed on a foam with which the subfloor is provided. Such a foam is usually compressible. The compressible foam allows a thicker bottom panel to be pushed toward the underbody so that the tongue groove is positioned on the thicker bottom panel at the same height as the spring of an adjacent bottom panel.
Such a submerged foam is conventionally used in the installation of laminate flooring, parquet floors, etc. When installing floors made of plastic, such as vinyl flooring, z. B. LVT (Luxury Vinyl Tiles), such a foam is conventionally not used.
Thus, the differences in thickness between different floor panels in joining the floor panels can lead to difficulties, especially when connecting the floor panels with the so-called Abklapp technique. The Ablapp technique involves mounting the floor panels by means of a vertical downward movement of an edge of one of the floor panels. As described above, bottom plates of different thicknesses can cause the spring groove of a bottom plate to be positioned at a different height than the spring of the adjacent bottom plate, resulting in difficulty in joining the bottom plates, since the bottom plates can not come into a locking position.
An object of at least certain embodiments of the present invention is to provide an improvement over the techniques previously described and the prior art.
Another object of at least certain embodiments of the present invention is to simplify the locking of the floor panels by means of a mechanical locking system.

The first and second edges are adapted to be mounted by a vertical downward movement of the second edge toward the first edge. The second edge is provided with a calibration groove adjacent the locking groove.
An advantage of embodiments of the present invention is that the calibration groove compensates for a difference in thickness at the edges of the floorboards, particularly for floorboards of different thickness. The sizing groove allows the second edge to be pressed towards the subfloor onto which the bottom plates are placed. In this case, the second edge can be shifted so that an upper side of the second bottom plate is matched with an upper side of the first bottom plate respectively at the first and second edges, even if the thickness of the second bottom plate exceeds the thickness of the first bottom plate.
