Abstract

The invention relates to a panel provided with two cover plates (1,2) and with insulating material located between said cover plates. A layer (9) of a fire-retardant material is provided between the cover plates (1,2), which is arranged between two layers (7,8) of an insulating material. At least one of the cover plates (1,2) may be profiled, seen in its longitudinal direction, in such a manner that parts of the cover plate (1,2) are staggered with respect to each other in a direction perpendicularly to the longitudinal direction of the panel.

Description

  • The invention relates to a panel provided with two cover plates and with layers of an insulating material and of a fire-retardant material located between said cover plates, whereby the layer of a fire-retardant material is provided between the two layers of a thermally insulating material abutting against said cover plates.
  • By a panel of this type, known from EP-B1-0.353.540 the layers of thermally insulating material consist of mineral wool. By this known panel all three layers, the two layers of thermally insulating material and the layer of fire-retardant material, contribute to a large extent to the fire-retardant aspects of the panel.
  • A disadvantage of the use of mineral wool as thermally insulating material is that machining of the layer of mineral wool, for example for the formation of grooves in the layer, is time consuming. Furthermore the moistureproofness and pressure resistance are relatively poor whilst the specific weight and the prize are relatively high.
  • It is an object of the invention to provide a panel whereby the disadvantages of the known panel have been overcome.
  • This object is achieved by a panel according to the invention in that said insulating material is an expanded polystyrene.
  • Although the layers of expanded polystyrene have nearly no fire-retardant effect it has surprisingly become apparent, that with such a construction of the panel it is still very well possible to meet the requirements with regard to the fire-retarding effect that are made of such panels, which are for example used for making walls in buildings. The provision of layers of expanded polystyrene on the outside of the core of the panel, which is to be clad with the cover plates, thereby offers great advantages with respect to the moisture proofness, pressure resistance, specific weight and price in comparison with a construction wherein the outsides of the panel to be clad with the cover plates are made up of layers of mineral wool.
  • In many cases the outer surfaces of the core of the panel made up of the layers of insulating material and fire-retardant material require machining, for example trimming or milling, so as to give the core its correct thickness and/or to form grooves which are to correspond with a profiled version of a cover plate.
  • The outer surfaces of a core can be worked much more easily when said outer surfaces are made up of an expanded polystyrene than when said outer surfaces are made up of mineral wool. Furthermore, when providing the cover plates on the core it will be readily possible to press any roughnesses still present in the insulating material or any impurities present on the insulating slightly into the layers of insulating material, so that an adequate smoothness and a taut outline of the cover plates can be ensured, while retaining conventional simple methods of providing the cover plates, which is of great importance in order to ensure an attractive appearance of the panels.
  • The invention will be explained in more detail hereafter with reference to the accompanying Figure, which is a diagrammatic perspective view of a part of a panel according to the invention.
  • The panel shown in Figure 1 comprises two cover plates 1 and 2 of a metal, for example steel, which make up the outside of the panel. As is shown in the Figure, the cover plates are profiled, in such a manner that for example parts 3 and 4 of cover plate 1 are staggered with respect to each other, in a direction perpendicularly to the longitudinal direction of the panel. In a similar manner the cover plate 2 comprises parts 5 and 6 which are staggered in a direction perpendicularly to the longitudinal direction of the panel.
  • The longitudinal edges of the cover plates 1 and 2 are flanged in the manner shown in the Figure, which is known per se, such that a longitudinal edge of corresponding panels fits between the flanged parts of the cover plates 1 and 2 of another longitudinal edge of a correspondingly shaped panel.
  • Two layers 7 and 8 of a thermally insulating material, generally expanded polystyrene, are provided between the cover plates 1 and 2, whilst a layer 9 of a special fire-retardant material is provided between said layers 7 and 8.
  • As already explained above, the outer layers of polystyrene can be readily machined, inter alia with a view to forming longitudinal grooves for receiving the deflected parts 4 and 5 of the cover plates 1 and 2. Partly because of the slightly resilient nature of the polystyrene said cover plates 1 and 2 can thereby be glued to the layers 7 and 8 of an insulating material in such manner as to closely abut against said layers.
  • It is preferred to form grooves 10 and 11 extending in the longitudinal direction of the profile in the longitudinal edges of the layer 9 of a fire-resistant material. When assembling a wall consisting of panels of this type tongues may be inserted in the grooves 10 and 11 of adjoining panels in order to prevent the occurrence of a leak near the layers of fire-retardant material.
  • Another possibility is to coat the sides of the layers 7 - 9 with a fire-resistant paint, which will foam at high temperatures, thus providing a seal between adjoining panels.
  • Furthermore a fire-retardant putty may be provided between adjoining panels when assembling a wall on the construction site.
