Definitions

  • the invention relates to a method for laying and locking panels, in particular by means of a fastening system consisting of form-fitting holding profiles provided on the narrow sides of the panels, which extend over the length of the narrow sides and are provided with joint projections or complementary socket recesses.
  • EP 0 855 482 A2 Another method for laying and locking panels is known from EP 0 855 482 A2.
  • Panels that are to be laid in the second row are also attached to the panels in a first row in an inclined position. Adjacent panels of the second row are first locked with the panels of the first row at a small lateral distance from one another. In this state, the panels of the second row can be moved along the first row.
  • By pushing two panels of the second row against each other holding profiles which are provided on the short narrow sides of the panels are pressed into one another. Disadvantageously, the holding profiles are greatly expanded and stretched.
  • the mounting profiles are already damaged during assembly, which affects the durability of the mounting profiles.
  • the holding profiles constructed and laid according to the teaching of EP 0 855 482 A2 are not suitable for multiple laying.
  • Holding profiles formed from an HDF or MDF material become soft due to the high degree of deformation to which the holding profiles are subject in the laying process according to EP 0 855 482 A2. Internal cracks and displacements in the fiber structure of the HDF or MDF material are responsible for this.
  • the object of the invention is therefore to simplify the known method for laying and locking and to improve the durability of the fastening system.
  • the object is achieved with a method for laying and locking square, panel-shaped panels, in particular floor panels, which on opposite long narrow sides and on opposite short narrow sides have holding profiles which extend over the length of the narrow sides and of which the opposite holding profiles are essentially complementary to one another are, first connecting a first row of panels on the short narrow sides, either by pushing together the complementary holding profiles of a laid and a new panel in the longitudinal direction of the short narrow sides or by first holding the holding profile of a new panel by tilting relative to the laid panel with the complementary holding profile of the installed panel and then by swiveling into the plane of the installed panel with it both in the direction perpendicular to the in one joined narrow sides as well as in the direction perpendicular to the plane of the installed panels, next a new panel is laid in the second row by first inserting the holding profile of its long narrow side with its holding profile by inclination relative to the long narrow side
  • panels to be installed in the second row can be installed by a single person.
  • a new panel can be locked with panels from the first row as well as with an already installed panel from the second row. For this, it is not necessary to lock the short narrow sides of two panels lying in one plane by widening and deforming the holding profiles.
  • the last panel laid in the second row can be gripped on its free short narrow side and can be swiveled upwards around the locked long narrow side as a pivot axis.
  • the panel is twisted a little around its longitudinal axis. This leads to the free short narrow side of the panel being in an inclined position and the inclined position decreasing towards the locked short narrow side of the panel.
  • a more or less strong torsion and thus a more or less decreasing inclination can result.
  • the inclination can continue through several of the previous panels of the second row.
  • the process can be carried out particularly well with thin and easily twistable panels.
  • the inclination of one in second row of thin panels decreases due to strong torsion at a very short distance.
  • the und twisted rest of a panel or row of panels in the installation level is securely locked. Only with the short slanted piece of the last panel of the second row can the holding profiles of the long narrow sides disengage during the laying work. But they can easily be put together again with the new panel attached to the short narrow side.
  • Rectangular, panel-shaped panels that have complementary holding profiles that extend along the length of the narrow sides on mutually parallel narrow sides, wherein a holding profile as a joint projection with a convex curvature and the complementary holding profile as a socket recess with a concave curvature, are particularly articulated and durable, with each joint projection of a new panel with a slight widening of the pan recess of a laid panel and the new panel is finally locked by swiveling into the level of the laid panel.
  • the deformation of the holding profiles necessary for laying and locking is considerably less than for holding profiles which have to be compressed perpendicular to their narrow sides in the laying plane.
  • the joint projection does not protrude further from the narrow side than the thickness of the panel. In this way, there is a further advantage that the holding profile can be milled on the narrow side of a panel with very little waste.
  • the holding profiles of the long narrow sides of two panels which are also referred to as form-fitting profiles, form a joint in the installed state of two panels, the upper side of the joint projection of a panel facing away from the substrate preferably having an oblique material removal which extends to the free end of the joint projection, and wherein the thickness of the joint projection due to the material Carrying to the free end is increasingly reduced, and the removal of material creates a freedom of movement for the joint.
  • the construction allows an articulated movement of two interconnected panels.
  • two panels that are connected to one another can be bent upward at the connection point. If, for example, a panel lies on a base with an elevation, so that a narrow side of the panel is pressed onto the base under load and the opposite narrow side bounces upwards, a second panel attached to the upward bobbing narrow side is also moved upwards.
  • the bending forces that arise do not damage the narrow cross-sections of the positive-locking profiles. Instead, a joint movement takes place.
  • a floor laid with the proposed fastening system has a flexibility which is adapted to irregular rough or corrugated surfaces.
  • the fastening system is therefore particularly suitable for panels for renovating irregular floors in old buildings. Of course, it is also better suited for laying panels on a soft intermediate layer than the known fastening system.
  • the construction takes into account the principle of "adapted deformability". This principle is based on the knowledge that very stiff and therefore supposedly stable connection points cause high notch stresses and therefore easily fail. In order to avoid this, components should be designed in such a way that they have a resilience or "adapted deformability" that is tailored to the intended use and in this way notch stresses are reduced.
  • the form-fitting profiles are designed so that a load on the top of the floor panels in the installed state from the top wall of the socket recess of a first panel into the hinge projection of the second panel and from the hinge projection of the second panel into the underside ge wall of the first panel is transferred.
  • the walls of the pan recess of the first panel come into contact with the top and bottom of the joint projection of the second panel.
  • the upper wall of the socket recess has only a short area at the free end of the upper wall of the socket recess in contact with the joint projection of the second panel.
  • the construction allows a slight movement of the joint between the panel with the socket recess and the panel with the joint projection with little elastic deformation of the walls of the socket recess.
  • the rigidity of the connection is optimally adapted to an irregular base, which inevitably leads to a buckling movement between panels fastened to one another.
  • a further advantage is seen in the fact that the laying and locking method according to the invention is better suited for multiple laying than the known methods, because the panels have no previous damage to the interlocking profiles after repeated laying and after long use on an irregular surface.
  • the form-fitting profiles are dimensionally stable and durable. They can be used much longer and can be relocated more often during their life cycle.
  • the convex curvature of the joint projection and the concave curvature of the socket recess essentially each form a circular section, the center of the circle of the circular sections being arranged on the top of the joint projection or below the top of the joint projection in the installed state. In the latter case, the center of the circle lies within the cross section of the joint projection.
  • the most protruding point of the convex curvature of the joint projection of a panel is arranged so that it is located approximately below the top edge of the panel. This results in a relatively strong cross section for the joint projection in relation to the total thickness of the panel.
  • the concave curvature of the socket recess provides a sufficiently large undercut for the convex curvature of the joint projection, so that these can hardly be moved apart by tensile forces acting in the laying plane.
  • the joint properties of two interconnected panels can be further improved if the wall of the pan recess of a panel facing the substrate has an inclined material removal on its inside, which extends to the free end of the wall and the wall thickness of this wall is increasingly thinner towards the free end.
  • the removal of material when two panels are installed creates freedom of movement for the joint. This improvement further reduces the amount of elastic deformation of the walls of the pan recess during the deflection of the installed panels.
  • socket recess of a panel for connection to the joint projection of another panel can be widened by a resilient deformation of its lower wall and that the resilient deformation of the lower wall which occurs during the joining is withdrawn again in the fully connected state of two panels.
  • the positive locking profiles are thus only elastically deformed for the joining process and during a joint movement and, if they are not loaded, are not subject to any elastic tension.
  • the ability to flexibly connect two panels on their short narrow sides also benefits the resilience of a floor covering.
  • the positive-locking profiles are preferably formed in one piece on the narrow sides of the panels.
  • the panels can be manufactured very easily and with little waste.
  • the laying process is particularly suitable if the panels consist essentially of an MDF (Medium Density Fiberboard), HDF (High Density Fiberboard) or a chipboard material. These materials are easy to process and maintain sufficient surface quality, for example by machining. In addition, these materials have a high dimensional stability of the milled profiles.

  • FIG. 8 is a perspective view of the method for laying and locking rectangular panels
  • Fig. 9 shows an alternative method for laying and locking rectangular panels.
  • the fastening system 1 required for the method for laying and locking rectangular panels is explained using the example of elongated rectangular panels 2 and 3, a section of which is shown in FIG. 1.
  • the fastening system 1 has holding profiles arranged on the narrow sides of the panels, which are designed as complementary form-fitting profiles 4 and 5.
  • the opposite form-fitting profiles of a panel are each complementary. In this way, a further panel 3 can be attached to each panel 2 that has already been laid.
  • the positive locking profiles 4 and 5 are based on the state of the art of the German utility model G 79 28 703 Ul. In particular on the positive locking profiles of the exemplary embodiment which is disclosed in FIGS. 14, 15 and 16 and in the associated description part of G 79 28 703 Ul.
  • the form-fitting profiles according to the invention are developed in such a way that they enable an articulated and flexible connection of panels.
  • One of the form-fitting profiles 4 of the present invention is provided with a joint projection 6 protruding from the narrow side.
  • the underside of the joint projection 6, which faces the base in the installed state has a cross section with a convex curvature 7 for the purpose of the articulated connection.
  • the convex curvature 7 is rotatably supported in the complementary form-fitting profile 5.
  • the convex curvature 7 is designed in the form of a circular section.
  • the part 8 of the narrow side of the panel 3 which is arranged below the joint projection 6 and which faces the base in the installed state is further back from the free end of the joint projection 6 than the part 9 of the narrow side which is arranged above the joint projection 6.
  • the part 8 of the narrow side arranged below the joint projection 6 steps back approximately twice as far from the free end of the joint projection 6 as the part 9 of the narrow side arranged above the joint projection 6. This is due to the fact that the circular section of the convex curvature 7 is relatively wide. As a result, the most protruding point of the convex curvature 7 of the joint projection 6 is arranged such that it is located approximately below the upper edge 10 of the panel 3.
  • the part 9 of the narrow side arranged above the joint projection 6 emerges from the narrow side at the top of the panel 3 and forms a joint joint surface 9a.
  • the part 9 of the narrow side is set back between this joint joint surface 9a and the joint projection 6 of the panel 3. This ensures that part 9 of the narrow side always forms a closed top-side joint with the complementary narrow side of a further panel 2.
  • the top of the hinge projection 6 opposite the convex curvature 7 of the hinge projection 6 has a short, straight section 11, which is also arranged parallel to the underground U in the installed state. From this short section 11 towards the free end, the top of the hinge projection 6 has an inclined material removal 12, which extends to the free end of the hinge projection 6.
  • the form-fitting profile 5 complementary to the form-fitting profile 4 discussed on one narrow side has a socket recess 20. This is essentially delimited by a lower wall 21 facing the subsurface U in the installed state and an upper wall 22. On the inside of the pan recess 20, the lower wall 21 is provided with a concave curvature 23. This has the function of a bearing shell.
  • the concave curvature 23 is also designed in the form of a circular section. So that the relatively wide concave curvature 23 can be accommodated on the lower wall 21 of the pan recess 20, the lower wall 21 protrudes further from the narrow side of the panel 2 than the upper wall 22.
  • the concave curvature 23 forms at the free end of the lower one Wall 21 an undercut.
  • this undercut is undercut by the joint projection 6 of the associated form-fitting profile 4 of the adjacent panel 3.
  • the degree of engagement that is to say the difference between the thickest point of the free end of the lower wall and the thickness of the lower wall at the lowest point of the concave curvature 23, is coordinated in such a way that a good compromise between an articulated flexibility of two panels 2 and 3 and a good hold against pulling apart the form-fitting profiles 4 and 5 is given in the installation plane.
  • the fastening system of the prior art according to FIGS. 14, 15 and 16 of the utility model G 79 28 703 U1 has a considerably larger degree of undercut. This results in extremely stiff joints, which cause high notch stresses due to the stress on an irregular surface.
  • the inside of the upper wall 22 of the pan recess 20 of the panel 2 is arranged parallel to the underground U in the installed state.
  • the inside of the wall 21 has an inclined material removal 24 which extends to the free end of the lower wall 21. This makes the wall thickness of this wall increasingly thinner towards the free end. According to the exemplary embodiment, the material removal 24 adjoins one end of the concave curvature 23.
  • the lower wall 21 of the socket recess 20 of the panel 2 in the installed state of the panels 2 and 3, creates freedom of movement 13 and 25, respectively, which allow the joint G to rotate in a small angular range.
  • the short straight section 11 of the top of the joint projection 6 of the panel 3 is in contact with the inside of the upper wall 22 of the socket recess 20 of the panel 2.
  • the convex curvature 7 of the joint projection 6 lies against the concave curvature 23 of the lower wall 21 of the pan recess 20 of the panel 2.
  • the side joint joint surfaces 9a and 26 of two connected panels 2 and 3 facing the upper side always lie clearly against one another.
  • the convex curvature 7 of the joint projection 6 of the panel 3 it is not possible for the convex curvature 7 of the joint projection 6 of the panel 3 to lie precisely against the concave curvature 23 of the socket recess 20 of the panel 2 at the same time.
  • Manufacturing tolerances would result in that either the joint faces 9a and 26 lie exactly against one another or the joint projection 6 / recess 20 exactly abut each other.
  • the positive-locking profiles are therefore designed so that the joint faces 9a and 26 always lie exactly against one another and the joint projection 6 / recess 20 cannot be moved sufficiently far into one another for an exact system.
  • the manufacturing tolerances are of the order of a hundredth of a millimeter, the joint projection 6 / recess 20 also nestle against one another almost exactly.
  • Panels 2 and 3 with the described complementary form-fitting profiles 4 and 5 can be attached to one another in different ways.
  • a panel 2 with a pan recess 20 has already been installed, while a second panel 3 with a complementary joint projection 6 is inserted obliquely into the pan recess 20 of the first panel 2 in the direction of arrow P.
  • the second panel 3 is rotated about the common center of the circle K of the circular sections of the convex curvature 7 of the joint projection 6 and the concave curvature 23 of the socket recess 20 until the second panel 3 rests on the substrate U.
  • FIG. 4 A further type of joining of the panels 2 and 3 discussed is shown in FIG. 4, according to which the first panel 2 is laid with a socket recess 20 and a second panel 3 with a joint projection 6 in the laying plane and perpendicular to the interlocking profiles 4 and 5 in the direction of arrow P. is moved until the walls 21 and 22 of the socket recess 20 expand a little elastically and the convex curvature 7 of the joint projection 6 has overcome the undercut at the front end of the concave curvature 23 of the lower wall and the final laying position has been reached.
  • the latter type of joining is preferably used for the short narrow sides of a panel if these are provided with the same complementary form-fitting profiles 4 and 5 as the long narrow sides of the panels.
  • 5 shows the fastening system 1 in use.
  • the panels 2 and 3 lie on an irregular surface U.
  • the first panel 2 with the form-fitting profile 5 has been loaded on its upper side.
  • the form-fitting profile 4 of the panel 3 connected to the form-fitting profile 5 has also been raised.
  • the joint G results in a kink between the two panels 2 and 3.
  • the freedom of movement 13 and 25 create space for the rotary movement of the joint.
  • the joint G formed from both panels 2 and 3 has been moved upwards a little from the laying plane.
  • the freedom of movement 13 has been fully utilized for the rotation, so that the upper side of the joint projection 6 of the panel 3 lies against the inside of the wall 22 of the panel 2 in the area of material removal 12.
  • the connection point is flexible in itself and does not impose any unnecessary and material-fatiguing bending load on the interlocking profiles 4 and 4 involved.
  • a further advantage results from a joint movement according to FIG. 5. This can be seen in the fact that the two panels fall back into their laying plane after being relieved by their own weight. In this case there is also a slight elastic deformation of the walls of the pan recess. This elastic deformation supports the panels falling back into the installation level. Only a very slight elastic deformation occurs because the pivot point of the joint, which is defined by the curved sections 7 and 23, is located within the cross section of the joint projection 6 of the panel 3.
  • FIG. 6 shows an articulated movement of two installed panels 2 and 3 in the opposite direction of rotation.
  • the on panels 2 and 3 laid on an irregular underground U are bent downwards.
  • the construction is designed in such a way that when the connection point bends out of the laying plane towards the substructure U, there is a significantly greater elastic deformation of the lower wall 21 of the socket recess 20 than when it bends upward from the laying plane.
  • the purpose of this measure is that panels 2 and 3, which have been bent downwards, cannot return to the laying level due to their own weight after being relieved.
  • the positive-locking profiles 4 and 5 described are integrally formed on the narrow sides of the panels 2 and 3 in the present case. This is preferably done by a so-called formatting process, in which the positive-locking profiles 4 and 5 mill the shape of the narrow sides of the panels 2 and 3 with a plurality of milling tools connected in series in one pass.

  • the panels are locked in the direction perpendicular to the installation level. They are also locked in the direction perpendicular to the plane of the narrow sides.
  • the free end 45a is pivoted upwards about the locked long narrow side 45b from the installation plane by a pivoting angle.
  • the panel 45 twists in such a way that the degree of the pivoting angle ⁇ decreases from the free end 45a to the locked end 45c.
  • the locked end 45c remains in the laying plane.
  • the new panel 46 is placed in an inclined position relative to the panel 45 at its free end 45a.
  • the panel 46 cannot initially be attached over the entire length of the short side, because the panel 45 is already locked with the panels 41 and 42 of the first row. Now the panel 46 is pivoted in the direction of arrow A until it is also positioned at the pivoting angle a to the laying plane, as shown by the dashed pivot position 46 '.
  • the panel 46 In the pivoting position 46 ', the panel 46 is shifted in the direction of arrow B and the joint projection of the panel 46 is inserted into the socket recess of the panels 42 and 43 of the first row R1. The short narrow side of the panel 46 is simultaneously pushed completely onto the short narrow side 45a of the panel 45. Finally, the panels 45 and 46 are pivoted together in the direction of arrow C into the laying plane and locked with the panels of the first row R1. Pre-damage to the holding profiles due to a high degree of deformation during installation and locking is avoided.
  • the alternative of the laying method according to FIG. 9 also provides that the free end 45a is pivoted upwards about the locked long narrow side 45b from the laying plane by a pivot angle ⁇ , the panel 45 twisting and at the free end 45a by a pivot angle ⁇ is inclined to the installation level.
  • the locked end 45c in turn remains in the laying plane.
  • the panel 46 is now also inclined at the swivel angle ⁇ to the installation plane and is slid on its short side 46a in the longitudinal direction onto the holding profile of the short side 45a of the panel 45. In this inclined position, the joint projection of the long side 46b of the panel 46 is immediately inserted into the socket recess of the panels 42 and 43 of the first row R1. Finally, the panels 45 and 46 are pivoted together into the installation plane and locked with the panels of the first row R1.
  • the alternatives for laying and locking panels consist in initially locking panels 45 and 46 in the laying plane on their short narrow sides.
  • the alternatives described here can be understood by looking at FIGS. 8 and 9, and therefore reference numerals are also given with regard to the alternatives that are not shown.
  • the holding profiles of the short narrow sides 45a and 46a of the panels 45 and 46 are pushed into one another in the longitudinal direction, while both panels 45 and 46 remain in the laying plane.
  • the panel 45 lies in the laying plane and the panel 46 is placed obliquely to the panel 45 on its short narrow side 45a and then pivoted into the laying plane.
  • the panel 46 is not yet locked on its long side with the panels 42 and 43 of the first row R1.
  • the panel 46 and the panel 45 must be raised at one end 45a into the above-described inclined position under the swivel angle ⁇ .
