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.
