Hard Floor Panel for Floating Installation with the Formation of a Flooring Panel Network

A hard floor panel with a core made of a wood-based panel, a wood-based plastic panel or a plastic panel with a top side and a bottom side and with side edges along the panel sides for floating installation to form a floor panel composite,

• wherein at least two floor panels are joined together,
• wherein the opposite side edges are provided with tongue and groove profiles,
• wherein a tongue and a joining surface are provided in a first side edge and a groove and a joining surface are provided in a second opposite side edge,
• wherein the spring of the first side edge has an upper side and a lower side;
• wherein a projection with a contact surface is provided on the lower side of the spring;
• wherein the joining surface of the first side edge extends from the upper side of the floor panel towards the upper spring side,
• wherein the groove in the second side edge has an upper side and a lower side,
• wherein the upper side of the groove is bounded by an upper lip and the lower side of the groove is bounded by a lower lip;
• wherein a recess with a contact surface is provided in the lower lip of the groove;
• wherein the joining surface of the second side edge extends from the upper side of the floor panel along the upper lip,
• wherein, in the joined state of at least two floor panels, the projection of the tongue engages in the recess of the lower lip of the groove so that the contact surfaces of the protrusion of the tongue and the recess of the lower lip of the groove exert a clamping force on each other;
• and
• wherein
• the joining surface of the first side edge is formed to extend at right angles to the upper side of the floor panel, and
• the joining surface of the second side edge is beveled and inclined inwards from the upper side of the floor panel, away from the vertical towards the groove,
• or
• the joining surface of the first side edge is beveled and is inclined inwardly from the upper side of the floor panel, away from the vertical and away from the tongue, and
• the joining surface of the second side edge is designed to run at right angles to the top of the floor panel,
• so that the angle between the top of the panel and the respective joining surface of the side edges is no longer right-angled, but forms an acute angle of between 85° and 89°, and that
• when the right-angled and beveled joining surfaces of the first side edge of the tongue profiling and the joining surface of the second side edge of the groove profiling are in contact with each other in the joined state of at least two floor panels, a line pressure occurs along the joining surfaces of the side edges of the tongue profiling and the groove profiling.
