Description
FIREPROOF WALL
The invention relates to a fireproof wall, comprising sandwich panels having first and second face skins and first and second attachment edges arranged on opposite edges of the sandwich panel.
It is known to use sandwich panels in buildings and con- structions as a wall element, a partition wall panel ele- ment, or a ceiling or roof panel element. In some applica- tions, there is need for fire resistant walls. In order to absorb impact energy due to a falling shelf, for example, the fixing system of the fire resistant walls needs to be flexible. This decreases risk of failures during fire and then decreases also costs affected by fire.
A disadvantage of existing sandwich panel wall structures designed to fulfill the requirements of fire wall impact loads 1s that they usually have rather complicated struc- tures which makes assembly work difficult and time consum- ing.
Viewed from a first aspect, there can be provided a fire- — proof wall, comprising sandwich panels having a first face
O skin of sheet metal, a second face skin of sheet metal, s 25 and a first and second attachment edges arranged on oppo- - site edges of the sandwich panel the attachment edge com- prising an attachment profile being formed from at least i one of said face skins and shaped for a tongue-and-groove
N attachment, the fireproof wall further comprising a joint
D 30 in where two sandwich panels are adapted to be connected
S to each other by at least one tongue-and-groove attachment by their attachment profiles, a fastener in the joint ar- ranged through a tongue of one of said two sandwich panels and a groove of another of said two sandwich panels, and a resilient fitting plate adapted to be attached on the joint, the resilient fitting plate comprising a first fit- ting edge adapted to be attached to a first of said two sandwich panels and a second fitting edge adapted to be attached to a second of said two sandwich panels, and at least one bulge arranged between said first and second fitting edges in parallel to the edges of said sandwich panels arranged in the joint, the bulge configured to ex- tend outwards away from the panels.
Thereby a fire wall structure having improved impact load resistance performance and maintaining simplicity of the wall structure may be achieved.
The arrangement is characterised by what is stated in the independent claim. Some other embodiments are character- ised by what is stated in the other claims. Inventive em- bodiments are also disclosed in the specification and drawings of this patent application.

The fireproof wall 100 comprises two or more sandwich pan- els 1 having first and second face skins 2, 3 and first and second attachment edges 4, 5 that are arranged on op- posite ends of the sandwich panel 1. Said attachment edges 4, 5 are counterparts to each other.
In an embodiment, at least one of the 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.
In an embodiment, said metal is steel, such as stainless steel. In some other embodiments, the face skin 2, 3 com- prises at least one of the following materials: copper, brass, titanzink. Typically, the first face skin 2 is made of same material as the second face skin 3, but not neces- sarily.
A core 15 1s arranged between said face skins 2, 3. The core is e.g. mineral wool, polyisocyanurate (PIR), polyu- rethane (PUR), or extruded polystyrene (XPS). - There is a joint 7 in where two sandwich panels 1 are con-
O nected to each other by the first and second attachment 00 edges 4, 5. The attachment edge 4, 5 comprises at least ? one attachment profile 6. The attachment profile 6 is
T 30 formed from at least one of the face skins 2, 3 and shaped
E in form creating a tongue 13 or a groove 14 of a tongue- 5 and-groove attachment. The sandwich panels 1 connect to 2 each other by said tongue-and-groove attachment. In an em-
N bodiment, such as shown in Figure 1, there are two attach-
N 35 ment profiles 6 in each of the attachment edges 4, 5 and thus also two tongue-and-groove attachments. First of the attachment profiles is formed from the first face skin 2 and second of the attachment profiles 6 is formed from the second face skin 3.
In an embodiment, such as shown in Figure 1, the attach- ment profile 6 1s 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 an- other way, too.
The joint 7 further comprises a fastener 12 that is ar- ranged through the tongue 13 and the groove 14 of the tongue-and-groove attachment. Typically, there are plural- ity of fasteners 12 arranged with suitable spacing in the entire length of the joint 7. The fasteners 1? 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 com- prises 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.
N In an embodiment, the fitting edges 9, 10 are parallel to
A the attachment edges 4, 5 of the sandwich panels. The fit-
P ting edges 9, 10 are arranged on both sides of the joint - 30 7 such that the resilient fitting plate 8 at least essen-
E tially covers said joint 7. = 3 In an embodiment, the resilient fitting plate 8 is at-
N tached to the sandwich panels 1 by second fasteners 16,
N 35 such as screws or rivets. The second fasteners 16 may be arranged with suitable spacing in the entire length of the fitting plate 8.
In an embodiment, such as shown in Figure 1, there are two resilient fitting plates 8 are arranged in the joint, on both sides of the fireproof wall 100. In another embodi- ment, the fitting plate 8 is arranged on one side of the fireproof wall 100 only.
The resilient fitting plate 8 comprises at least one bulge 11 arranged between the first and second fitting edges 9, 10 and in parallel to the attachment edges 4, 5 of the sandwich panels 1. The bulge 11 extends outwards, i.e. away from the panels 1 and the joint 7. In the embodiment shown in Figure 1, there is just one bulge 11 in the re- silient fitting plate.
The resilient fitting plate 8 is configured to deform, e.g. expand or bend, in the area of the bulge 11 from its original shape (shown in Figures) into another shape. Ac- cording 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 7. The resilient fitting plate 8 is distributing the energy of the loads or shocks
N over length of the plate 8 and also over a prolonged peri-
A od of time. Thus, the resilient fitting plate 8 may pre-
P vent the sandwich panels 1 from coming loose from each - 30 other. = a = Figure 3 is a perspective view of a resilient fitting x plate. In an embodiment, the length 1 of the resilient
N fitting plate 8 is equal or at least substantially equal
N 35 to the length of the joint 7. In another embodiment, the resilient fitting plate 8 is substantially shorter than the joint 7. In this embodiment, the joint 7 may be cov- ered by using two or even more resilient fitting plates arranged one after another on the joint 7.
In an embodiment, 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 in- stance.
In an embodiment, the thickness of the resilient fitting plate 8 is in range of 0,5 mm —- 1,5 mm. In an embodiment, the thickness of the resilient fitting plate is in range of 0,5 mm — 0,7 mm.
In an embodiment, the thickness of the resilient fitting plate 8 is at least essentially constant all over the plate. In another embodiment, 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 bulge(s) 11 therebetween. In an embodiment, the thicker structure has been made by turning the plate mate- rial double on the edges thereof. Thus, the attachment of the resilient fitting plate to the sandwich panels may be reinforced, without scarifying resilient characters there- of.
N In an embodiment, the width W of the resilient fitting
A plate 8 is in range of 30 mm — 200 mm. In an embodiment,
P the width W is in range of 50 mm - 100 mm. - 30
E The resilient fitting plate 8 comprises at least one bulge
K 11 arranged between the first and second fitting edges 9, 3 10 and in parallel or at least substantially parallel to
N said edges. In the embodiments shown in Figures, there is
N 35 one bulge 11 in the resilient fitting plate 8. In some other embodiments, there may be two or even more bulges 11 in the resilient fitting plate 8.
In an embodiment, the deepness of the bulge 11 is in range of 5 mm —- 100 mm. In an embodiment, the deepness is in range of 8 mm - 50 mm. The "deepness” means dimension of the resilient fitting plate perpendicular to its length L and width W.
Figure 4a is a schematic view of a resilient fitting plate, and Figure 4b is a schematic view of another resil- ient fitting plate.
In some embodiments, the resilient fitting plate 8 com- prises just one bulge 11 only. In another embodiment, the resilient fitting plate 8 comprises at least two bulges 11, for instance two, three or four bulges.
In an embodiment, the bulge 11 has a sinusoidal shape. In another embodiment, the bulge 11 has a wavy shape. In an- other embodiment, the bulge 11 has an arched shape. In still another embodiment, the bulge 11 has 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 men- _ tioned above.
