A well-known wall element consists of two sheet metal shells of the same size, a sealing strip made of elastic material and arranged between the shell edges and from insulating plates, which fill the H space between the metal shells.

When used as an outer wall, the individual wall elements are over Brackets suspended from building supports. Similar wall elements also serve as floor-to-ceiling partition walls for interiors.

However, the heat and sound insulation of these wall elements is poor.

It is therefore up to us to improve the heat and sound insulation and avoid corrosion.

In the case of a wall element consisting of opposing block shells, the end a seal located between the shell edges and a seal housed in the cavity According to the invention, insulation is at least one parallel to the insulation Wall-extending insulation group, composed of two high-gloss, heat rays reflective foils and intervening chambers, the walls of which are made of insulating material exist, provided. A highly effective insulation is achieved in this way. The e.g. The heat absorbed by the outer wall is shared by that on the inside Slide with. Only a few heat waves emanate from this high-gloss film and penetrate it the chambers meet the opposite film and are almost completely covered by it reflected, so that the second film is only slightly heated. The chambers will made of insulating material, e.g. in the form of honeycomb panels or perforated plastic foam panels. They have thin walls so that only small amounts of heat are transferred through the walls The chambers are small and tightly sealed, so that even through Convection of the air can hardly transfer heat.

If such isolation groups are arranged one behind the other., Off Foils and chambers, the effect is correspondingly increased many times, making the highest Requirements can be met, between each additional group an insulating plate, E.g. fiberglass mat, plastic foam board, which the heat conduction between two reflective foils.

Insulating plates,, B. made of plastic waiting foam, be arranged, which sound to the formation Chambers on both sides Have ribs. To reduce the contact surfaces for heat transfer follows on an insulating plate with horizontal ribs an insulating plate with vertical ribs Instead of whole panels, only strips with ribs alternating horizontally and vertically can be used against the reflective foil lying in between the ribs can be made with reflective strips or the ribbed plate can be completely be covered with reflective foil.

The isolation chambers can be of (approx. 5 mm) narrow, continuously perforated Insulating panels, for example made of rigid plastic foam, can be formed on both sides highly reflective foils are tightly sealed, with the remaining plastic foam structure forms the geometric shape of the chamber walls.

To avoid the formation and accumulation of condensation water can be pre-dried Air must be introduced into the wall elements and this via an air drying system, at the same time to compensate for the atmospheric pressure fluctuations with the outside air stay in contact.

In addition, the cavity can be evacuated. A heat transfer convection is then excluded. This also has the advantage of that prevents the formation of condensation and the associated corrosion will.

Several examples are shown in the drawings. It shows: Fig 1- Parts of two adjoining wall elements in a vertical section as an outer wall attached to a building ceiling, FIG. 2 shows a section through a wall element Insulation by plates and honeycombs Fig. 3 an insulating plate with horizontal ribs, FIG. 4 with vertical ribs, FIG. 5 with interrupted ribs, FIG. 6 a section by a wall element with insulation by strips and plates, and FIG. 7 shows a Section through a wall element with insulation by honeycomb and covered with foil Plates, Fig. 8 parts of two abutting wall elements in vertical section with a sheet metal outer shell and a plaster inner shell, FIG. 9 a perforated insulating foam panel with reflective foils on both sides.

In Fig. 1, rails 1 with a Z-shaped cross-section are provided by screws 1 a attached to the front edge of a building ceiling 2.

The upper rail carries in with its flange facing outwards upper wall element 3 and the lower rail holds the upper edge of a lower wall element 3, Each wall element consists of an outer block shell 3 a and an inner one Sheet metal grinder 3 b. Between the edge partOn 3 c, 3 d of the shells is a Insulating and sealing strips 10, preferably made of hard rubber, laid. Penetrate screws 11 the edge parts, the weather strip and the rails. They press the metal bowls Airtight to each other and at the same time hold the wall elements ai building. In the cavity insulation is housed between the Bloch shells, which at least consists of a highly effective isolation group extending parallel to the shell walls consists. The insulating group is made up of a high-gloss, heat rays reflecting thin film, e.g. made of aluminum, made up of small narrow chambers 8, the walls of which are made of Consist of insulating material, and formed from a further reflective film, the Foils seal the chambers.

According to a first example chambers are formed from honeycomb panels 8 a, whose preferably 5 mm high webs 8 b extend between the film and the counter-film. There are still insulating groups between the foils of the three insulation groups shown Plate 9, e.g. made of felt cardboard or plastic foam or glass fiber mats, for Reduction of heat transfer and placed for stiffening. For good looks and for rust protection, the sheet metal shells are externally covered with a coating 4 made of lacquer or Plastic and inside with a de-drumming film or mass 5 and a stiffening plate 6 equipped.

When the outer Bloch shell is exposed to sunlight, the adjacent one heats up first slide. However, the high-gloss film radiates very little heat inwards, compared to a black body only about a fifth. The tone of the slide outgoing Heat rays penetrate the chambers, hit the counter foil and are released from its high-gloss surface almost completely (approx 93%) and only a small part (7%) is absorbed1 so that -ie heats up little and only a little Can pass on heat (1.25%).

The heat transfer through radiation is therefore very low.

Furthermore, there is heat conduction through the layers resting on the foils Bars of the honeycomb instead. But since the cross-sectional area of the adjacent to the foils The webs only make up about 4% of the total film area and the webs are made of insulating material exist, the heat conduction is also very low. Värie can finally get through too Convection of the trapped air are transmitted. Because through the honeycomb panels very many and therefore small chambers are formed, air can hardly be circulated arise and heat transfer can take place. Become multiple isolation groups arranged one behind the other, the effect is considerably increased. In one attempt with five insulation groups, the outer sheet metal shell is at a temperature of loo brought and kept at this temperature while the inner sheet metal shell was exposed to a room temperature of 200. After four hours, she was in a state of restraint achieved. The temperature of the inner sheet metal shell had increased from 200 to 300 elevated. At an outside temperature of 70 °, the temperature of the inner Bloch shell rose at 70 and at an outside temperature of 45 ° by 30.

The honeycomb walls can be made of highly reflective, very thin metal surfaces (e.g. by evaporation of aluminum in a vacuum). For fire protection reasons the honeycombs can be fire-receiving by impregnation or the like. Likewise fiberglass mats can be insulating on the insides of the wall shells, as well E.g. between 2 aluminum foils each, through which the wall element, along with don reflective Metal foils and sheets (heat reflection ) and the impregnated and hardened honeycombs, extremely good against the effects of fire is coming of fire.

The gap between two wall elements can be turned towards the outside by means of angle plates 13, which are held by the screws 11, and ton screens 14, which are behind grip springy tongues on the angle plates, be closed. For further heat and sound insulation to the interior of the room, the inner sheet metal shells can be a Wear reflective foil and spacer strips 15. There will be one on both sides Plastered plasterboard 16 coated with reflective foils, which by angle 17 on Building is held and forms the interior space.

A second example is shown in FIGS.

The wall element 3 consists of the outer sheet metal shell 3 a and the inner sheet metal shell 3 b. Both have a coating 4 on the outside. The pickled Isolation consists of six isolation groups. The two middle groups are off Honeycomb panels 8 a, as in the first example, produced. The outer groups are from insulating panels 51, e.g., made of rigid plastic foam, which on both Side lips 51 z have and (about 5 mi narrow) strip-shaped chambers S form. In Fig. 3 is an Isolierplatto flit horizontal ribs 51 a, ii Fig. 4 one with vertical lips 51 b and in Fig. 5 one with rows of projections 51 c in view shown. A second reflective film 7 and one follow the first insulating plate second insulating plate, the ribs of which perpendicular to those of the first Stand insulating plate. This allows heat conduction only at the crossing points of the ribs take place. A third reflective foil closes the chambers. Between The insulating groups can be arranged sheets 9, which at large pressures, e.g. When evacuating, the thin reflective film is pressed in through which only point by point connect opposing webs of the honeycomb panels or the ribs of the insulating panels. If the sheets themselves are highly reflective, the foils can be omitted.

In a third example, only insulating strips are used instead of insulating plates used, the contact surfaces of which have ribs. In Fig. 6 are the sheet metal shells 3 a, 3 b provided with coatings 4 on the outside. The first isolation group is from horizontal Insulating strips 52 formed with ribs 52 a, which by gluing to the adjacent Reflective foils 7 'can be held. The second group has vertical insulating strips 53 with ribs 53 a. This is followed by a third group with horizontal and one fourth group with vertical stripes. Heat transfer occurs in the chambers hardly open through conversion. In the middle are two groups of insulating plates 51 with horizontal ribs and appropriate reflective foils. About that In addition, reflective film strips 7 a are inserted into the recess, whereby the Thermal radiation in the insulating plate is greatly reduced.

According to the fourth example in FIG. 7, there are 3 on the sheet metal shells a, 3 b with the coatings 4 inside each two insulating groups of honeycomb panels 8 a with the associated reflective foils 7 at. In the middle is an isolation group arranged with an insulating plate 51 which has ribs 51 a on both sides. The ribs can be produced by pressing or rolling. Here you can at the same time reflective foils are attached by gluing, so that the walls of the Insulating plate are completely covered with reflective foil0 In Fig. 8 is a fifth Example shown. On the sheet metal shells 3 a with an outer coating 4 lie seven insulating groups made of insulating foam panels 71, with cylindrical perforations 71 a, sealed on both sides by reflective foils 7, narrow insulating chambers forming with still air.

The wall element is made of plasterboard towards the inside of the seam 16 completed, the to the last insulating group with a reflective sheet 7 are coated. The outer wall shell 3 a and the inner plaster wall shell 16 are connected with a plastic screw 72. A nut 72 is provided for this purpose a welded on the inside of the wall shell 3 a using the stud welding process. The edge sealing of the wall element is carried out by insulating strips 54, e.g. made of hard foam.

Fig. 8 shows the connection of an upper and lower wall element by means of corresponding, encompassing bends 3 d, 3 e, which are riveted 73 are connected.

To reduce contact and thus heat conduction, it is advantageous to roughen the surfaces.

Hoses protrude through the gypsum plates 16 into the interior of the wall element or pipes 75, which the airtight wall elements with an air drying system and connect the atmosphere.

According to the atmospheric pressure fluctuations is about this Air drying system with increasing atmospheric pressure dried air from the wall elements added and with falling atmospheric pressure released again. The pressure in the wall element is equal to the atmospheric pressure in the same at every point in time, without moisture getting into the wall element can. This causes the formation of condensation in the wall element and the resulting conditional prevention or heat reflection and increased thermal conductivity, as well possible destruction of the insulating elements and also rusting of the sheet steel surfaces and cut edges avoided.

A further increase in insulation can be achieved by evacuating the air the cavity can be achieved between the sheet metal shells. The individual Provide wall elements with valves or all wall elements through a pipe be connected to an evacuation system. The evacuation includes heat transfer by convection. In addition, condensation is prevented, which could reduce the reflectivity of the high-gloss reflective films.
