Definitions

  • the invention relates to a wall, comprising an inner skin manufactured substantially from plate material and an outer skin manufactured substantially from plate material, wherein:
  • an insulating layer manufactured from mineral wool is placed between the inner skin and the outer skin
  • the inner skin is provided with noses placed at regular distances and directed toward the interior of the wall,
  • the noses are connected to the outer skin by means of pointed connections, and
  • the noses are located at a distance from the outer skin.
  • Such a wall is known from EP-A-0 801 190.
  • thermal insulation value is understood to mean not only the normal measurable insulation value, but that the fire- retardation is also very important. It is of course of the greatest importance to ensure that the construction is as fire-resistant as possible. Fire-retardation is often also very important in respect of legal regulations.
  • the object of the present invention is to provide such a construction wherein the resistance to wind load is much greater without the noses having to be placed considerably closer together or the pointed connections having a greater closeness or having to have excessively heavy dimensions.
  • the insulating layer has a greater density on the outside than on the inside and in that the pointed connections are adapted to absorb forces in the direction parallel to the plane of the wall.
  • lateral forces are at least partially absorbed by the pointed connections without the pointed connections having to be embodied in excessively heavy form.
  • the pressure forces are absorbed by the mineral wool with a high density and transmitted on the one hand to the layer of mineral wool of a lower density located therebehind and on the other hand to the noses.
  • a construction is known from EP-A-0 849 420 wherein mineral wool with a higher density is applied on the outside, albeit in combination with a screw connection which is not suitable for absorbing lateral forces. This is an attempt to obtain a combination of a thick layer of mineral wool on the inside with an acceptable thermal insulation and low cost, and a thinner layer of mineral wool with a greater density located on the outside with the purpose of obtaining a sturdier construction and an optimal thermal insulation.
  • the problems associated herewith are obviated by the measure according to a first preferred embodiment of the invention, wherein the density of the layer of mineral wool progresses smoothly from a low density on the inner skin to a high density on the outer skin.
  • the forces perpendicularly to the plane of the wall are herein transmitted without discontinuity due to the uniform progression of the density.
  • a good distribution over the surface of the wall herein takes place .
  • the density on the inner side of the wall is practically constant over a considerable part of the total distance toward the outer side.
  • the part with the practically constant density extends at least as far as the noses .
  • the whole space in the cassette is filled.
  • the occurrence of channels extending in lengthwise direction, which can result in convection, is hereby prevented.
  • the low density lies between 30 and 40 kg/m 3 .
  • optimization on the other side i.e. a sufficiently high density to obtain the mechanical strength necessary there while still making a contribution toward the thermal insulation, is obtained when the high density lies in the range between 55 and 85 kg/m 3 .
  • the specific fibre direction of the mineral wool extends transversely of the main plane of the wall.
  • figure 1 shows a partly broken-away perspective view of a wall construction according to the present invention
  • figure 2 shows a graph of the density curve of the mineral wool by way of elucidating the present invention.
  • FIG. 1 Shown in figure 1 is a wall construction designated as a whole with "1", which is fixed to vertically extending profiles 2.
  • an inner skin 3 which is formed by cassettes extending in substantially horizontal direction.
  • the cassettes are provided with a wall fixed against the profiles and with bent noses designated as a whole with "4".
  • an outer skin 6 Arranged on the outside is an outer skin 6 which is formed by a metal plate. This is preferably corrugated.
  • Outer plate 6 is connected to the noses by means of screw connections 7. Up to this point the construction corresponds with the construction described in EP-A-0 801 190.
  • a block of mineral wool 8 is arranged in the space between inner skin 3 and outer skin 6.
  • the density of the block of mineral wool progresses in the direction transversely of the direction of the wall construction from a low value of about 35 kg/m 3 on the inner side to a high value of about 65 kg/m 3 on the outer side. This progression is smooth so as to avoid discontinuities, particularly in the path of forces.
  • the density from the inner side as far as the length of noses 4 is substantially constant at the low value in this configuration.
  • Figure 2 shows the density graphically. This shows that the density is practically constant over a total length of roughly 90 mm, this being the thickness of noses 4. The density then increases in a smooth curve to the recommended value of 65 kg/m 3 . The advantages elucidated in the preamble are thus obtained.

Abstract

L'invention concerne une paroi qui comprend une peau interne sensiblement constituée d'un matériau pour plaques et une peau externe, qui est aussi sensiblement constituée d'un matériau pour plaques. Dans cette cassette: - une couche isolante en laine minérale est placée entre les peaux interne et externe; - la peau interne comporte des becs disposés à intervalles réguliers et orientés vers l'intérieur de la paroi; - ces becs sont reliés à la peau externe au moyen de raccords à pointe; et - ils sont placés à une certaine distance de la peau externe, la couche isolante ayant une densité plus grande du côté extérieur que du côté intérieur, et les raccords à pointe sont conçus pour absorber les forces dans une direction parallèle au plan de la paroi. Ces caractéristiques permettent d'obtenir une plus grande rigidité latérale de la structure de cloison. La densité de la couche de laine minérale, faible au niveau de la peau interne, augmente progressivement et est élevée au niveau de la peau externe.
