Definitions

  • the present invention relates to a joint structure for structural sandwich panels comprised of a mineral wool core clad on both wide faces by skin sheets.
  • the skin sheets in such panels known in the art are conventionally made from sheet metal bonded to the mineral wool core.
  • the core is made from so-called structural mineral wool having an essential integral strength.
  • the shear strength of the core material is in the order of 25 - 100 kN/cm 2 .
  • the core and the skin sheet are bonded together using an adhesive.
  • edges of the panels are fabricated into a tongue-and- groove structure formed from the skin sheets thus facili- tating the jointing of the panels.
  • the mineral wool core is left unclad at the panel edges over at least a portion of the edge surface remaining between the tongue- and-groove members formed by the skin sheets .
  • the tongue-and-groove structures and the mineral wool core are dimensioned so that when the panels are ready mounted in place using the tongue-and-groove locking, the unclad edges of the mineral wool core remain resting against each other.
  • Such an integrity of the joint is extremely important not only for the sake of thermal insulation, but also in a crucial manner to counteract fire spreading.
  • the mineral wool core of the panel is extremely fire-resistant, but due to contraction or movement of the mineral wool, crevices may appear in the joint structure that deteriorate the fire resistance performance.
  • the advantageous goals defined above are attained according to the invention by severing the bonding strength from the initially tight bond of said edge to the skin structure over at least a portion of at least one of the unclad edges of the cores to be mated and for a depth at least essen ⁇ tially equal to half the height of the tongue-and-groove joint structure.
  • mineral wool has a somewhat resilient structure.
  • the structural mineral wool used as the core of a panel has a high compressive strength.
  • the wool is also conventionally adhesively bonded to the skin up to the edge of the tongue-and-groove structure, inward compression of the mineral wool core during the panel mounting step neces ⁇ sitates to overcome, not only the compressive strength of the wool, but also the shear strength of the bond to the skin, which has prevented the utilization of the resilience of the mineral wool in prior-art joint structures.
  • the core is made compressible at the joint area by providing the mineral wool forming the panel core with a possibility of undergoing contraction under compression over the entire area of the mating surfaces in the joint.
  • the mating area in the joint is provided with a separate sealer strip of more resilient (softer) mineral wool than that used in the panel core proper.
  • the resilience of the mineral wool core at the joint also facilitates new kinds of joint structures between the skin sheets by virtue of locking notches/tabs cut in the tongue- and-groove edges of the skin sheets .
  • the panel core is fabricated slightly overextending at the edges.
  • the joint edge of the panel core is then severed to include cuts or furrows extending toward the interior of the panel core and running parallel with the joint edge of the panel.
  • the pur ⁇ pose of such cuts or furrows is to reduce the compressive strength imparted by the bonding of the core to the skins and thus to give the panel core a greater compressive resilience at its joint edge freed from the counteracting effect of shear forces to the compression.
  • the cuts made as narrow furrows provide the mineral wool with more space for compression.
  • the cuts or furrows can be made approx. 15 - 50 mm deep depending on the wool type.
  • the cuts or furrows can be made only on one of the mating edges, or alternatively, on both. If the cuts or furrows are made on both of the mating joint edges, their depth can be smaller than when they are made on the edge of only one of the mating panels .
  • the mineral wool core of the panel must be left slightly undersized. Fabrication of the core to an undersize can be attained by, e.g.
  • Figure 1 is a cross-sectional view of the mating edges of two panels to be joined, said edges including two alternative structural details fabricated according to the invention
  • Figure 2 is a perspective view of an embodiment of a mutual locking arrangement for the side sheets of two panels to be joined;
  • Figure 3 is a perspective view of an alternative embodi ⁇ ment of a locking arrangement for the same purpose
  • Figure 4 is a perspective view of a further alternative embodiment of a locking arrangement for locking the skin sheets to each other;
  • Figure 5 is a perspective view of further another alter ⁇ native embodiment of a locking arrangement for locking the skin sheets to each other;
  • Figure 6 is a cross-sectional view of an alternative embodiment of the joint structure according to the invention shown in the diagram of Fig. 1.
  • the panels comprise a core 1 made from a mineral wool board and clad on both sides by a skin sheet 2.
  • the skin sheets are bonded to the core using an adhesive.
  • the skin sheets are shaped into conventional tongue- and-groove structures 3, 3 ' .
  • the panel edges are left unclad at the area used for the tongue-and-groove joint so that the mineral wool core surface remains bare.
  • said bare surfaces of the mineral wool core 1 advantageously mate with each other in a slightly compressed state.
  • the mineral wool core 1 in the joint edge of the lower panel is severed by cuts 4 made extending from the surface of the bare core toward the interior of the panel core and running parallel with the joint edge of the panel.
  • the purpose of such cuts is to detach that part of the mineral wool core remaining between the cuts from that part of the mineral wool core which is tightly bonded to the skin sheets 2.
  • Said cuts can be to a depth of approx. 20 - 50 mm deep, either to one or both of the edges of the panels to be jointed.
  • the cuts 4 made in the mineral wool core can also be implemented as narrow furrows which provide the mineral wool in the core with more space for compression.
  • the cuts made in the mineral wool core 1 are fabricated as narrow furrows 5 and 6, which are aligned obliquely into the mineral wool core 1 at an angle relative to the plane of the panel.
  • Such furrows can be aligned from the joint surface obliquely either toward the center plane of the panel core, or alternatively, toward the panel surface.
  • Said slit-like cuts 4 or furrows 5, 6, 6' can be made in a greater number staged in the thickness direction of the panel, however, without compromising the required total strength of the joint structure.
  • the cuts and furrows may be made with different orientation angles and/or depths relative to each other.
  • a useful joint structure is also achievable by virtue of working the initially cohesive structure of the mineral wool comprising the core so as to impart the wool greater flexibility and easier compressibility. Such a working must be done by weakening the mutual binding of the mineral fibers.
  • a proper working method is, e.g., sufficiently vigorous compression of the mineral wool over the entire length of the joint edge using, e.g., a reciprocating press roll apparatus. This kind of a working process detaches the mutual adherence of the fibers bonded with a binder, thus resulting in greater fluffiness of the mineral wool. Simultaneously, the volume of the worked wool increases, thus providing a suitable sealer strip of resilient wool for the joint.
  • This working method can be applied to both joint edges included the above-described separating cuts and joint edges without such separating cuts.
  • a locking arrangement of the skin sheets is shown which is particu ⁇ larly advantageously suited for use in the present joint structure.
  • the skin sheets 2, 2' are bent to form a tongue-and-groove joint comprising flanges 2a, 2b, which protrude orthogonally outward from the plane of the panel and are shaped to mate tightly parallel with each other when the panels are abuttingly mounted in place.
  • Each of the flanges is fabricated to include locking notches 5, 5' .
  • the notch 5 in the flange 2a at the upper edge of the panel is made by either entirely removing the flange material at the notch, or alternatively, slitting the sheet material (Fig. 3, ref . numeral 5'") -
  • the flange 2b at the lower edge of the panel is worked so that a part of the material cut free at the notch 5 ' is bent along the base line of the notch inward to form a catch claw 5" .
  • this claw can during the mounting of the panels be pressed to slide under the bottom edge of the notch 5 in the panel upper edge flange 2a.
  • Such a mutual locking of the skin sheets provides an essen- tial improvement to the mutual locking of the skin sheets in, e.g., a fire occasion, thus limiting the mutual distor- tional or translational movement of the panels relative to each other to a smaller scale than occurs in panels with a conventional joint structure.
  • the mutual locking of the flanges can also be attained using alternative notch/tab embodiments some of which are shown in Figs . 4 and 5.
  • the edges of the notches 5 are made lockable to each other by means of locking tabs partially cut loose from the sheet material at the notch, after which said locking tabs can be brought to lock with each other by moving the panels to be jointed so that they slide relative to each other in the direction of the joint.

Abstract

Structure de jonction de panneaux stratifiés constitués d'un noyau (1) en laine minérale dont les deux faces sont avantageusement revêties de pellicules (2) liées au noyau en laine minérale. Le noyau (1) en laine minérale est dénudé au bord d'un assemblage (3, 3') à fausse languette faisant partie de la structure pelliculaire de revêtement, de sorte que les surfaces des noyaux en laine minérale des panneaux à joindre puissent être couplées. Pour assure l'étanchéité du joint, le noyau (1) en laine minérale est soumis dans la zone de l'assemblage à fausse languette à une plus grande contraction par compression dans la direction de couplage des panneaux que partout ailleurs dans le noyau, une fois que les structures pelliculaires de revêtement des panneaux ont été mises en place dans leurs assemblages à fausse languette.
