Definitions

  • the invention relates to a panel with a panel upper side and a panel lower side and with at least two opposing panel edges, each of which has an edge break in the form of a bevel on the panel upper side, the edge breaks in turn forming a joint in a covering surface when connected to one another, the edge breaking one of the panel edges is made larger than the edge break of the opposite panel edge, and that a lower part of the large edge break of one panel edge is overlapped in the connected state by the small edge break of the opposite panel edge.
  • the panels usually have decorative surfaces.
  • the invention relates to a panel of the above type which is intended to be glued to a load-bearing substrate.
  • Such panels are used, for example, as floor panels and glued to a screed, etc.
  • the opposing panel edges of the proposed panel have contoured panel edges which are designed complementary to one another, i. H. In principle, two panel edges of the same panel can be joined together if the panel were severed.
  • Panels that are intended to be glued to a substrate often do without contoured panel edges. You then simply have flat panel edges that are arranged perpendicular to the top of the panel and butt against each other. On the other hand are in favor of bonding Panels with contoured panel edges are known which have complementary tongue and groove. Tongue and groove panels can also be glued to the substrate, but in many cases they are intended for floating installation and not glued to the substrate. Then only the tongue and groove edges are glued together.
  • the edge breaks at the top of the panel edges represent a blunt effect, which makes the respective edge less sensitive to mechanical impacts and in this way protects the panel edges.
  • the joints between panels that are joined to one another can be irregular in practice. Although panel edges are pressed against each other when glued to a substrate, inclinations and gaps can arise, which disrupt the desired uniform appearance of a covering surface. Edge breaks, which together form a joint or notch, help to hide inequalities such as misalignments or gaps a little.
  • a generic panel (board) according to DE 10 2011 111 166 A1 viewed, which proposes at least two boards for a floor covering made of wood, which are arranged with their long sides to form a joint next to one another in a laying plane.
  • the joining connection has: an engagement section, which is designed in such a way that the two adjacent boards can be held in the laying plane and mobility transverse to the laying plane can be prevented, and a first contact section in which a projection is seen on at least one side surface of a board in cross section is formed in the width direction of the board, which rests at its distal end on a portion of the side surface of the adjacent board, so that the movements of the board in the width direction during swelling and shrinking can be compensated for by the elastic deformation of the projection.
  • this structure is it is possible to keep the boards in the laying plane by means of the engagement section and to elastically compensate for movements during swelling and shrinking due to changes in moisture by means of the projection of the contact section, with a closed surface of the floor covering being maintained
  • a panel in the form of a cuboid dry screed slab for a subfloor in dry construction having a slab height direction, a first, flat broad side of the screed slab, in particular a screed slab support surface, a second broad side of the screed slab opposite this in the slab height direction, in particular a screed slab top, and four screed slab side surfaces adjoining each other in pairs (20 ), each having a rebate, the dry screed panel having at least one first rebate and at least one complementary, second rebate, and the rebates each having a first rebate joint surface, a second rebate joint surface and a rebate contact surface in between, characterized in that the first rebate joint surface of the first rebate has a first, inclined clamping surface and the complementary first rebate joint surface of the second rebate has a second, inclined clamping surface
  • the first two rabbet surfaces are designed in such a way that after two dry screed panels have been put together in such a way that the two step rabbets interlock with one another in
  • the DE 102 56 501 A1 proposes a panel, in particular a floor panel, made of a wood material, which is provided with means for releasably connecting at least two panels, with positive locking elements for locking in the vertical direction and in the horizontal direction with a further panel being formed on at least one side edge of a first panel, whereby from Starting from a top side, a bevel is formed on at least one side edge, as well as a method and a device for producing such a panel.
  • the bevel should at least be covered with a layer of lacquer.
  • a panel called a floor element as a flexible object.
  • a decorative sheet is laminated on the surface of a woody substrate by impregnating and solidifying pattern paper obtained from melamine resin.
  • a vinyl chloride resin-based resin mat is laminated on the back of the substrate.
  • a tongue and groove connection is formed in each of four circumferential end faces of the base element in such a way that a central part has a tongue and a groove.
  • several floor elements can be continuously connected to one another in a continuous manner by means of a construction connecting material. The adhesive strength of the construction connecting material is lower than the delamination strength of each floor element.
  • the invention is based on the object of proposing a panel provided for gluing to a substrate with an improved design of at least two opposing panel edges for thin panels.
  • the object is achieved in that a projection is provided on that panel edge with the large edge break, which has a rounded shape at the free end, that the complementary panel edge has a recess that is provided with a matching round shape so that the projection nestles against the cross-section of the recess, and that in the assembled state the panel edges can be centered relative to one another by means of the projection and the recess and a locking can be effected against the panels moving apart in a direction perpendicular to the panel plane.
  • the new design of the opposing panel edges means that any gap is less noticeable than with a covering surface made of known panels. If the broken edges of two panel edges are joined together to form a joint, then there may be a gap at the bottom of the joint. Due to the design of the large edge breakage and the small edge breakage, however, a gap can never arise that could be viewed vertically from above by a viewer. As a result, the appearance of a flooring surface is far less disturbed than a flooring surface made of known panels.
  • the design of the panel edges is particularly suitable when the panel is to be made very thin overall.
  • An undercut contour with a lateral projection is expediently provided on a panel edge in an upper area near the panel top, the small edge break being located at the top of the lateral projection of this contour.
  • the lateral projection preferably forms the distal area of the panel edge. No other area of the panel edge protrudes laterally than this lateral projection.
  • the lateral projection has a blocking surface facing the underside of the panel.
  • the overlapped part of the large edge break in the connected state is aligned parallel to the blocking surface that is provided on the contour of the lateral projection.
  • the overlapped area of the large edge break cannot move unhindered perpendicular to the plane of the panel in the direction of the panel top, because the blocking surface of the lateral projection blocks the path.
  • a recessed abutment surface is provided between the underside of the panel and the lateral projection. This abutment surface limits the joining path when two panels are moved against each other in the panel plane and perpendicular to their panel edges.
  • the free end of the complementary panel edge also expediently has an abutment surface which interacts with the abovementioned abutment surface arranged below the lateral projection. If the abutting surfaces of the complementary panel edges are aligned perpendicular to the panel plane, then this avoids the creation of a force component acting perpendicular to the panel plane, which is an undesirable one Height offset of the panel edges could result.
  • the opposite panel edges can each have a lower edge break on the underside of the panel.
  • the resulting blunting protects the respective edge from damage.
  • the edge breaks also form a joint on the underside of the covering. This favors the bonding in that the adhesive that has been applied to the underside of the panel can flow to the joint on the underside. So adhesive gets at least a little way between the panel edges and can also get between the abutting surfaces and glue them to one another, whereby an additional material bond is produced between the abutting surfaces and the strength of this connection is improved.
  • That panel edge with the lateral projection can have a lower edge break that is equal to or greater than the lower edge break of the complementary panel edge.
  • This embodiment can be designed, for example, so that the large edge break on the underside of the panel extends so far that it intersects the small breakage on the top of the panel.
  • the entire panel edge then forms an asymmetrical point, with each of the two edge breaks forming a flank of this point.
  • the two flanks of the tip can differ in size, angle and surface shape. For example, the surfaces do not have to be planes.
  • the underside of the panel can be prepared as an adhesive underside.
  • This can be adhesive tape that is applied to the underside of the panel or, for example, an adhesive that has to be activated in order to develop its adhesive effect.
  • the adhesive underside is created by that the surface quality of the underside of the panel is prepared for good adhesion of an adhesive. The adhesive is then applied during the manufacture of a covering surface.
  • a method for gluing a panel according to the invention in which the adhesive is applied to the underside of the panel, but with an edge area of the underside of the panel remaining free of adhesive. An edge area around the underside of the panel is not provided with adhesive.
  • the adhesive can flow to the edge region of the underside of the panel and some of it reaches between the panel edges.
  • this can be, for example, a reactive adhesive or a reactive adhesive.
  • a reactive adhesive can in particular be understood to be an adhesive of this type whose curing is based on a chemical reaction, such as a polymerization, for example a polyaddition or polycondensation. In particular, the reaction can produce large-molecular, cross-linked plastics of high strength.
  • reaction partners are involved in the reaction.
  • the reaction partners can, for example, be combined and mixed immediately before processing, in which case it is a 2-component adhesive.

  • the panel can first be laid and then the adhesive can be activated by pressing the panel from above.

It goes without saying that activation can also take place before the installation.
