Definitions

  • the invention relates to wall or ceiling panels of a building forming a tongue and groove joint without fastening elements, said panels comprising a metallic outer surface plate, a metallic inner surface plate arranged at a thickness from the outer surface plate, and heat insulation therebetween; in said tongue and groove joint, the groove is placed at the first edge of the panel and comprises a fold that is bent inwardly from one of said edges of the surface plate in a second direction, and, as an extension thereof, a first bend pointing in the opposite first direction inside said thickness; and the tongue is placed at the other edge of the panel and comprises a bead strip extending outwards, in said second direction of a surface plate, and as an extension thereof, a second bend pointing in said first direction inside said thickness.
  • the invention relates to a fire resistant panel of this type.
  • tongue and groove joints provided between wall or ceiling panels made of metallic surface plates and insulation provided therebetween, are not the best possible joints.
  • One such tongue and groove joint between light panels is described in the publication WO-01/77457 .
  • the panel described in said publication comprises an upper and a lower metal or plastic plate, and therebetween, insulation made of elastic material, such as mineral wool.
  • the publication relates to a hidden joint provided between the panels, by which joint the panels are attached to the load-bearing structure.
  • the joining to the load-bearing structure is carried out by screw fasteners at the tongue provided at the panel edge, and through a plate-like additional load distribution element arranged in between the screw head and the metal or plastic plate constituting the tongue and groove.
  • the groove edge of the adjacent panel covers said fasteners and load-distributing elements.
  • the publications GB-2,142,670 and EP-1,260,647 describe somewhat more complicated tongue and groove joints, which are provided with reinforcing additional folds of the plate, when compared with the tongue and groove of the above mentioned WO publication.
  • the tongue and groove of the GB publication is designed as a snap-on joint, which means that the making of the tongue and groove joint requires the use of considerable strength.
  • the high rigidity of the elements of the tongue and groove joint makes the installation difficult in other ways, too, especially if the elements of the tongue and groove joint have formal defects.
  • the object of the invention is to realize a tongue and groove joint of the type described in the beginning of this specification, which joint would have a distinctly better fire resistance than the prior art tongue and groove structures, and which joint would also otherwise have better airtightness and watertightness than known tongue and groove joints.
  • Another object of the invention is to achieve said main objects without using any fire resistant paint or other thermally expanding mass between the insulations of the connected panels, and also without locking the tongue and groove joint with screws or similar means.
  • a third object of the invention is to achieve, for a tongue and groove of this type, also a shape that does not result in mutual matching problems when installing the panels in place, as is sometimes the case with known seam solutions.
  • both the tongue section and the groove section are designed in the tongue and groove joints of wall or ceiling panels so that they include folds and first bends as extensions of the surface plates, and in addition by arranging, as extensions of said bends, another set of inner flanges, at the same time as the tongue bend is preferably arranged on the opposite side of the bead strip than the surface plates, there is achieved a shape-locked joint between the tongue and the groove.
  • the shape-locked joint that is achieved owing to these several plate bends or plate folds, designed according to the invention, drastically improves the sealing of the tongue and groove, particularly in the case of a fire.
  • the reason for this improvement is that in the tongue and groove joint, the combustion gases infiltrating through the plate bends are in the case of a fire conducted towards the heat insulation, and not directly to the seam joint of the insulations provided between the panels, in which case also the insulation capacity remains good, in addition to the improved sealing.
  • the same conducting of the combustion gases works in both directions.
  • the groove part is set precisely and reliably, without wedging, in the tongue part, because the tongue and groove parts do not include inclined surfaces.
  • the wall or ceiling surface formed of the panels is smooth.
  • the panel surface plates cannot slide or slip apart.
  • a double sealing can be utilized in this tongue and groove joint.
  • a flow of water, caused by rain and wind, that attempts to penetrate into the tongue and groove joint it can be prevented by a capillary groove or water-preventing trough according to the invention.
  • the capillary groove is invisible, hidden in the vertical part of the tongue; owing to the expanded transversal surface, it prevents the water from rising deeper in the tongue and groove joint, and is left invisible after the installation of the next panel.
  • the capillary groove can also be used as an extra sealing in the tongue and groove joint, by extruding for instance sealing mass therein, either in the factory or during the installation step at the building site.
  • Fig. 1 illustrates a first embodiment of the tongue and groove according to the invention, seen in a cross-section in perpendicular to the panel plane and to the length of the tongue and groove joint.
  • Fig. 2 illustrates a second embodiment of the tongue and groove according to the invention, seen in the same view as in figure 1 , in a cross-section in perpendicular to the panel plane and the length of the tongue and groove joint.
  • the figures illustrate a panel construction to be used as wall or ceiling panels 1 in a building.
  • This kind of light ceiling or wall panels comprise a metallic outer surface plate 3a, a metallic inner surface plate 3b placed at a thickness W1 thereof and heat insulation 6 in between said two surfaces.
  • the heat insulation is generally mineral wool, but in some cases other heat insulations can also be used, such as foam polymers, for instance foam polyurethane or the like.
  • Each of two superimposed wall panels 1a, 1b and respectively each of two adjacent ceiling panels 1a, 1b are interconnected at the edges by means of a mutual tongue and groove joint 2 without a fastening element.
  • a fastening element is not provided means that in between the groove 7 and the tongue 8, there are not provided any mutually fastening elements, but there may be provided fasteners, such as screws or bolts, that penetrate the tongue alone and attach it to structures, not illustrated in the drawings. In the preferred embodiments illustrated in the drawings, not even these are provided, but the panels are fastened by other means.
  • the absence of a mutual fastening element between the groove and the tongue enables a self-sealing capacity to be described below.
  • the groove 7 of the tongue and groove joint is provided at the first edge of each panel and comprises a fold 4a or 4b, folded from said edge of a surface plate inwards in said panel 1a, towards the tongue 8, i.e. in the second direction D2, and as an extension thereof, a first bend 9a, 9b pointed in the opposite first direction D1, i.e. outwards towards the edge 1a of said panel, inside the panel thickness W1.
  • the tongue 8 of the tongue and groove joint is located at the second edge of each panel, said edge being opposite to the first edge, and comprises a bead strip 5a or 5b, extending outwards from said panel 1b of a surface plate, towards said edge, i.e. when the groove and tongue are mutually attached, in said second direction D2, and as an extension thereof, a second bend 10a, 10b pointing in said first direction, i.e. in this case towards the panel 1b, inside said panel and in the direction D1 towards said groove 7, inside said second thickness W1.
  • a common reference number 1 For special purposes, there can naturally be made panels that are mutually different. If said panel 1 is used as a wall panel or a ceiling panel installed in an inclined position, the tongue 8 is provided at the top edge of the panel, and the groove 7 is provided at the bottom edge of the panel.
  • the first direction D1 points downwards, and the second direction D2 points upwards.
  • the directions D1 and D2 are parallel with the center line connecting the panel edge on the tongue side and the panel edge on the groove side. If the surface plates are in parallel, the directions D1, D2 are also parallel with them.
  • the groove 7 comprises a fold 4a, 4b and a first bend 9a, 9b as an extension of both surface plates 3a and 3b
  • the tongue 8 is provided with a bead strip 5a, 5b and a second bend 10a, 10b as an extension of both surface plates 3a and 3b, which thus means that the first tongue and groove section 31 located on the side of the first surface plate 3a is essentially of the same type as the second tongue and groove section 32 located on the side of the second surface plate 3b.
  • the first and second tongue and groove sections 31, 32 are not necessarily mutually identical or located at precisely the same height in the directions D1, D2, but according to the invention, they are in principle corresponding in shape, and contain sections or shapes that are functionally of the same type.
  • the second tongue and groove section 32 can be located upper, i.e. shifted in the direction D2, or lower, shifted in the direction D1, the curvatures to be dealt with below can be of different orders etc.
  • the first and second tongue and groove section 31, 32 are identical in measures, in which case the tongue and groove joint 1 is mirror symmetrical with respect to the center plane that is parallel with the panel surface plates.
  • the bead strips 5a, 5b of the tongue 8 according to the invention, as well as the folds 4a, 4b of the groove 7 arranged on both sides thereof, can be essentially parallel with the surface plates 3a, 3b, as is depicted by unbroken lines in the drawings, but especially the tongue bead strips 5a, 5b can also in the second direction D2 approach each other, so that the bead strips form, with respect to the direction of the surface plates, an angle K3 that is smaller than 10°, generally not larger than 7° and typically of the order 5°, as is depicted by dotted lines in figure 1 .

  • the second angle K2 can be equal to the first angle K1, but advantageously the second angle K2 is larger, for example by 5° - 10° larger than the first angle K1.
  • Said second bend 10a, 10b of the tongue is placed on the opposite side of the bead strip 5a and respectively 5b, than the outer surface plate 3a or respectively the inner surface plate 3b.
  • the distance W2 between the folds 4a, 4b is smaller than the thickness W1 of the wall elements, and in addition the distance W2 of these folds 4a, 4b is larger than the distance W3 of the bead strips 5a, 5b of the tongue 8, but by no more than for the length of the first clearances P1.
