Hard flooring panel for laying in a floating manner to form a flooring panel composite

Abstract

The present invention relates to a hard flooring panel (1) with a top side (2) and a bottom side (3) and side edges (10, 20) along the panel sides, for laying in a floating manner to form a flooring panel composite, at least two flooring panels being joined together in each case, the opposing side edges (10, 20) being provided with tongue-and-groove profiles, a tongue (11) and a joining face (16) being provided in a first side edge (10), and a groove (21) and a joining face (26) being provided in a second, opposite side edge (20), the tongue (11) of the first side edge (10) having an upper side (12) and a lower side (13); wherein a protrusion (14) having a contact face (15) is provided on the lower side (13) of the tongue; wherein the joining face (16) of the first side edge (10) runs from the top side (2) of the flooring panel towards the upper tongue side (12), and the joining face (16) is chamfered; wherein the groove (21) in the second side edge (20) has a top side and a bottom side, the top side of the groove (21) being delimited by an upper lip (22), and the bottom side of the groove being delimited by a lower lip (23); wherein a cut-out (24) having a contact face (25) is provided in the lower lip (23) of the groove; wherein the joining face (26) of the second side edge (20) runs from the top side of the flooring panel along the upper lip (22), and the joining face (26) is chamfered; wherein, when at least two flooring panels are joined together, the protrusion (14) of the tongue (10) engages in the cut-out (24) in the lower lip (23) of the groove so that the contact faces (15, 25) of the protrusion (14) of the tongue and of the cut-out (24) in the lower lip of the groove exert a clamping force on each other; and wherein, when the chamfered joining faces (16) of the first side edge (10) of the tongue profile and the chamfered joining face (26) of the second side edge (20) of the groove profile bear against each other in the joined-together state of at least two flooring panels, a linear pressure is produced along the chamfered joining faces (16, 26) of the side edges of the tongue profile and of the groove profile.

Description

technical field [0001] The invention relates to a hard floor panel for floating laying to form a floor panel composite, in particular a laminate floor. Background technique [0002] Floor panels with a tongue-and-groove profile at the side edges for laying into panel composites, such as laminate flooring, are widespread and generally known. The profile enables simple laying of the floor panels as a floor covering. Such floor coverings can consist, for example, of wood fiber boards or plastic boards. Typically, floor panels are provided with a decorative layer and a wear-resistant surface layer. [0003] The commonly used tongue-and-groove profiles however have the disadvantage that gaps of different sizes are formed between the mutually abutting panels. Dirt and also moisture can penetrate into these gaps and cause expansion or expansion of the carrier plate of the floor panel, especially when a wooden material board is used as the carrier plate. Expansion or expansion o...
