System element against noise and heat

The innovation affects one. System element against noise and heat - consisting in particular with high radiation intensity from a sheet metal cassette filled with insulating material.

Large enclosures are known in which elements with seals placed in between, which are made of elastic cords or plastic straps can be placed on top of one another will. j

In production systems with innovations, such as in the case of an electric melting furnace, there is a risk of that the seals are directly exposed to high temperatures or even flames. As a result, the seal burns and then loses its function. :

The innovation is based on the task of finding a stackable element, which in addition to good thermal insulation and a high absorption and sound insulation ability is resistant to short-term radiant heat and can be completely prefabricated in the workshop.

The innovation was achieved in that a flat side of the sheet metal cassette in the area of the side walls according to the system of protruding or recessed box-shaped body made of absorbent material is arranged, which by means of a covering perforated plate to .der

Sheet metal cassette is held and that on the other flat side in the area of the side walls alternately to sheet metal strips are attached to the neighboring system elements.

In addition to good thermal insulation, the system element has a high level of acoustic impermeability. The construction is largely insensitive to flames, which can sometimes occur in fire establishments in the event of a breakdown. Due to the interlocking - the protruding parts and sheet metal strips are '■' - arranged according to a system in the case of neighboring system elements - the encapsulation has a high level of stability.

In a particular embodiment, the offset makes im Area of the side wall at least the thickness of the box-shaped body.

This offset enables a sufficiently rigid and functional encapsulation.

An example of the innovation is shown in the sectional drawing and is described in more detail below.

On the sheet metal cassettes 1, which are covered with thermal insulation 2 are filled, are on the Fiachseita, 3 box-shaped Body 4 made of mineral wool as absorption material with | a cover made of perforated plate 5 attached offset, so that the protrusion from the adjacent system element engages in the offset of the next system element.
