  • two resilient fitting plates are arranged in the joint, on both sides of the fireproof wall.
  • An advantage is that even stronger structure may be achieved, and also good fire-resistant properties on both sides of the wall.
  • the resilient fitting plate comprises just one bulge only.
  • the cross-sectional shape of the bulge is selected from sinusoidal shape, wavy shape, arched shape, crested shape, or any of their combination.
  • An advantage is that properties of resiliency may be selected in a broad range.
  • the resilient fitting plate is made of metal.
  • An advantage is that a pliable and flexible but still sturdy resilient fitting plate may be achieved.
  • the attachment edge comprises at least two attachment profiles, for instance two, so that a first attachment profile is formed from the first face skin and a second attachment profile is formed from the second face skin.
  • An advantage is that a robust structure of the joint may be achieved in a simple way.
  • At least one of the attachment profiles is arranged on the outer surface of the sandwich panel such that an outer surface of a lip/outer edge of the groove is flush with the outer surface of the respective face skin.
  • An advantage is that the attachment profile is easily reachable with the fastener.
  • the resilient fitting plate is adapted to be attached to the sandwich panels by second fasteners.
  • Figure 1 is a schematic view of a fireproof wall in partial cross-section
  • Figure 2 is a schematic view of a detail of the fireproof wall in partial cross-section.
  • the fireproof wall 100 comprises two or more sandwich panels 1 having first and second face skins 2, 3 and first and second attachment edges 4, 5 that are arranged on opposite ends of the sandwich panel 1. Said attachment edges 4, 5 are counterparts to each other.
  • first and second face skins 2, 3 is sheet of metal, in a further embodiment both first and second face skins 2, 3 are sheet of metal.
  • said metal is steel, such as stainless steel.
  • the face skin 2, 3 comprises at least one of the following materials: copper, brass, titanzink.
  • the first face skin 2 is made of same material as the second face skin 3, but not necessarily.
  • a core 15 is arranged between said face skins 2, 3.
  • the core is e.g. mineral wool, polyisocyanurate (PIR), polyurethane (PUR), or extruded polystyrene (XPS).
  • the attachment edge 4, 5 comprises at least one attachment profile 6.
  • the attachment profile 6 is formed from at least one of the face skins 2, 3 and shaped in form creating a tongue 13 or a groove 14 of a tongue-and-groove attachment.
  • the sandwich panels 1 connect to each other by said tongue-and-groove attachment.
  • the attachment profile 6 is arranged on the outer surface of the sandwich panel 1 in a way that an outer surface of a lip or outer edge 17 of the groove is flush with the outer surface of the respective face skin 2, 3. This way a quite imperceptible joint can be created. It is to be noted, however, that the lip or outer edge 17 may be arranged another way, too.
  • the joint 7 further comprises a fastener 12 that is arranged through the tongue 13 and the groove 14 of the tongue-and-groove attachment.
  • a fastener 12 that is arranged through the tongue 13 and the groove 14 of the tongue-and-groove attachment.
  • the fasteners 12 may be e.g. screws or rivets.
  • the joint 7 further comprises a resilient fitting plate 8 that is attached on the joint 7, to the outer surfaces of the sandwich panels 1.
  • the resilient fitting plate 8 comprises a first fitting edge 9 for attaching to a first of said two sandwich panels 1 and a second fitting edge 10 for attaching to a second of said two sandwich panels 1.
  • the fitting edges 9, 10 are parallel to the attachment edges 4, 5 of the sandwich panels.
  • the fitting edges 9, 10 are arranged on both sides of the joint 7 such that the resilient fitting plate 8 at least essentially covers said joint 7.
  • the resilient fitting plate 8 is attached to the sandwich panels 1 by second fasteners 16, such as screws or rivets.
  • the second fasteners 16 may be arranged with suitable spacing in the entire length of the fitting plate 8.
  • fitting plate 8 there are two resilient fitting plates 8 are arranged in the joint, on both sides of the fireproof wall 100.
