AI Technical Summary

Technical Problem

Existing panels experience water penetration and mold growth at transverse and longitudinal joints, particularly at the intersection points, leading to structural integrity and aesthetic issues.

Method used

The panel edges are redesigned with a retaining groove for the locking element positioned lower on the mounting hook, creating a greater distance from the panel top, and a cap formed by retaining the upper portion of the spring profile to enhance sealing, combined with complementary hook profiles and chamfers to prevent separation and improve watertightness.

Benefits of technology

The redesign significantly enhances sealing at T-joints, preventing water ingress and mold growth, ensuring improved structural integrity and aesthetic quality of panel surfaces.

Abstract

The invention relates to a panel (A, B, C, D) with a panel core (E), a panel top (0), a panel bottom (G), and with a first pair of edges and a second pair of edges, wherein the first pair of edges is provided with a groove profile (1) on one panel edge (N) and a complementary spring profile (2) on the opposite panel edge (F), which interact in such a form-fitting manner that, in the locked state, a movement of locked panels apart in the plane of the panels (horizontally) is counteracted, wherein the second pair of edges is provided on its opposite panel edges with complementary hook profiles, namely a receiving hook (3) and a locking hook (6), wherein the locking hook (6) can be joined to the receiving hook (3) by an joining movement in a direction perpendicular to the panel plane, with the proviso that the receiving hook (3) has a retaining groove (41, 67) for a separate locking element (5, 66, 73, 80, 86,93) is provided with which a vertical locking effect can be achieved, wherein at a corner (K1) of the panel (A, B, C, D) the spring edge (2) of the first pair of edges meets the receiving hook (3), wherein the retaining groove (41, 67) provided on the receiving hook (3) of the second pair of edges for the locking element (5, 66, 73, 80, 86, 93) is provided with an upper groove wall (43, 68) which has a distance (L2) to the top of the panel (O) that is greater than the distance (L1) between the top of the panel (O) and the top of the spring (19) of the spring profile (2) of the first pair of edges.
