Definitions

  • the invention relates to a fireproof wall, comprising - sandwich panels having first and second facings and first and second edges arranged on opposite ends of the sandwich panel.
  • a disadvantage of existing sandwich panel wall structures designed to fulfill the requirements of fire wall impact loads usually require rather heavily constructed and complicated fixings and support structures which makes assembly work difficult and time consuming.
  • JP H02 197670 A discloses a wall with a joint section comprising a fire proofing inorganic sheet and a back batten underneath a wall panel joint section, wherein the joint section is covered with metal fixture to fix to the body after caulking.
  • the joint is provided with a resilient fitting plate with only one bulge directed away from the joint.
  • a fireproof wall comprising
  • the resilient fitting plate is made of metal.
  • first and the second fitting edges have a thicker structure than the two or more bulges therebetween.
  • the cross-sectional shape of the two or more bulges is selected from sinusoidal shape, wavy shape, arched shape, crested shape, or any of their combination.
  • the joint is arranged to have a joint gap between the two sandwich panels being adapted to be connected to each other in said joint.
  • the joint gap is adapted to be filled with a filling material.
  • a protective element is adapted to be arranged on outer side of the resilient fitting plate.
  • a thermally isolating material is adapted to be arranged between the protective element and the resilient fitting plate.
  • the supporting element is a metal profile.
  • the resilient fitting plate is adapted to be attached to the sandwich panels by fixation means.
  • the resilient fitting plate is adapted to be attached to the supporting element by fixation elements extending through the composite panel.
  • Figure 1 is a schematic top view of a fireproof wall in partial cross-section and Figure 2 is a schematic perspective view of a resilient fitting plate shown in Figure 1 .
  • the fireproof wall 100 comprises two or more sandwich panels 1 having first and second facings 2, 3 and first and second edges 4, 5 that are arranged on opposite ends of the sandwich panel 1.
  • first and second facings 2, 3 is sheet of metal, in a further embodiment both first and second facings 2, 3 are sheet of metal.
  • said metal is steel, such as stainless steel.
  • the facing 2, 3 comprises at least one of the following materials: copper, brass, titanzink, aluminiun.
  • the first facing 2 is made of same material as the second facing 3, but not necessarily.
  • a core 17 is arranged between said facings 2, 3.
  • the core is e.g. mineral wool, polyisocyanurate (PIR), polyurethane (PUR), or extruded polystyrene (XPS).
  • joint 6 there is a joint 6 in where two sandwich panels 1 are connected to each other.
  • a clear joint gap 12 between the first and second edges 4, 5 in the joint 6.
  • the joint gap is preferably filled with a filling material 13, such as a fireproof isolation material, e.g. mineral wool.
  • a supporting element 7 is adapted to be attached to two, at least, sandwich panels 1 in the joint 6.
  • the supporting element 7 is a part or element of a framework of building. In an embodiment, the supporting element 7 is a part of wall structure of a building.
  • the supporting element 7 may be manufactured from metal, concrete, wood etc.
  • the supporting element 7 is a metal profile made of steel.
  • the supporting element 7 is arranged on side of the first facings 2 of the sandwich panels 1.
  • the wall is an outer wall of a building, and the first facing 2 is arranged inside side of that outer wall.
  • the supporting element 7 is arranged outside the building.
  • the wall is a partition wall, and thus both of the facings 2, 3 are inside the building. The distance of the edges 4, 5 of the two sandwich panels in the joint 6 is less than the corresponding width of the supporting element 7.
  • a resilient fitting plate 8 is attached on the joint 6 on side of the second facings 3 of the sandwich panels 1.
  • the resilient fitting plate 8 comprises two fitting edges, so that a first fitting edge 9 is attached to a first of said two sandwich panels 1 and a second fitting edge 10 is attached to a second of said two sandwich panels 1.
  • the resilient fitting plate 8 is configured to deform, e.g. expand, from its original shape (shown in Figures) into another shape. According to an aspect, the deformation is permanent or at least mainly permanent by its nature. This ability to change shape of the resilient fitting plate 8 enables it to absorb dynamic impact loads or shocks incurred on the sandwich panels 1 and the joint 6.
  • the resilient fitting plate 8 is distributing the energy of the loads or shocks over length of the plate 8 and also over a prolonged period of time. Thus, the resilient fitting plate 8 may prevent the sandwich panels 1 from coming loose from the wall and the supporting element 7.
  • fitting edges 9, 10 are parallel to the edges 4, 5 of the sandwich panels.
  • the length of the resilient fitting plate 8 is equal or at least substantially equal to the length of the joint 6. In another embodiment, the resilient fitting plate 8 is substantially shorter than the joint 6. In this embodiment, the joint 6 may be covered by using two or even more resilient fitting plates arranged one after another on the joint 6.
  • the resilient fitting plate 8 is made of metal, such as steel.
  • the shape of the fitting plate may be formed by bending and edging or pultrusion, for instance.
  • thickness of the resilient fitting plate 8 is in range of 0,5 mm - 1,5 mm.
  • the resilient fitting plate 8 there are two or more bulges 11 directed away from the joint and arranged between the first and second fitting edges 9, 10 and in parallel or at least substantially parallel to said edges. In the embodiment shown in Figures 1 and 2 , there are two bulges 11 in the resilient fitting plate 8.
  • height of the bulges 11 is in range of 5 mm - 50 mm.
  • a protective element 14 is arranged on outer side of the resilient fitting plate 8.
  • the protective element 14 may be e.g. a metal plate, made of same or different material as the facings 2, 3.
  • the protective element 14 is attached to the panels 1 so that it envelopes both sides of the resilient fitting plate 8.
  • a thermally isolating material 15 is adapted to be arranged between the protective element 14 and the resilient fitting plate 8.
  • the thermally isolating material may be e.g. mineral wool.
  • the resilient fitting plate 8 is attached to the sandwich panels 1 by fixation means 16, such as screws or rivets.
  • the fixation means 16 may be arranged with suitable spacing in the entire length of the fitting plate 8.
  • the resilient fitting plate 8 is attached to the supporting element 7 by fixation elements 18 that extends thereto through the composite panel 100.
  • the fixation element 18 may be e.g. a screw.
  • Figure 3 is a schematic view of another resilient fitting plate.
  • the first and the second fitting edges 9, 10 of the resilient fitting plate 8 has a thicker structure than rest of the resilient fitting plate or the bulges 11 therebetween.
  • the thicker structure has been made by turning the plate material double on the edges thereof.
  • Figure 4 a schematic view of a third resilient fitting plate and in Figure 5 a schematic view of a fourth resilient fitting plate.
  • the resilient fitting plate 8 comprises just one bulge 11 only.
  • the resilient fitting plate 8 comprises three or four bulges.
  • the bulges 11 have a sinusoidal shape. In another embodiment, the bulges 11 have a wavy shape. In another embodiment, the bulges 11 have an arched shape. In still another embodiment, the bulges 11 have a crested shape. In an embodiment, the resilient fitting plate 8 comprises bulges 11 having different cross-sectional shapes, for instance any combinations of the shapes mentioned above.
