    I Thermally insulated wall and process for its manufacture
    The invention relates to a thermally insulated wall and a method for its manufacture. From DE 26 23 355 Al is a thermally insulated wall with a
    Wall element, which has a surface, with rigid foam panels, which are fixed on the surface of the wall element and have outer surfaces, and with aluminum panels, which have inner surfaces facing the outer surfaces, to which the rigid foam panels are glued.
    EP 0 478 084 A1 discloses an adhesive bond between a facade panel and a facade construction with a first adhesive in the form of a 2 mm thick double-sided adhesive tape and with a second adhesive which has a higher adhesive strength and a greater thickness than the first adhesive. When assembling, the facade panel is only slightly pressed in a first step and completely in a second step. The second adhesive fixes the facade panel immediately after contact is made with it in the second step. This means that the facade panel can only be moved before the second step.
    WO 2012/059757 A2 discloses an adhesive bond between a rail or plate and a facade, in particular it relates to the planking of shipping containers. A first adhesive in the form of a double-sided adhesive tape and a second adhesive which has a higher adhesive strength than the first adhesive are used. Both adhesives are the same
    Thickness applied. The first adhesive immediately fixes the rail or plate, the second adhesive does not initially have sufficient strength to hold the rail.
    From EP 2 441 898 A2 an adhesive bond of a U-shaped steel profile to a facade panel is known. A profiled plastic profile is glued to the steel profile using double-sided adhesive tape. It has a rib on its surface facing the facade panel and takes up another double-sided adhesive tape on the side of the rib, which forms a first adhesive and does not protrude as far as the rib. In addition, a second adhesive is applied to the steel profile in a thickness so that the second adhesive protrudes approximately as far as the first adhesive. The assembly takes place in 2 steps
    BE2016 / 0008 from. First the facade panel is placed on the rib, in this position it can be moved. Then it is pressed on in a second step, thereby coming into contact with the first adhesive, which fixes it immediately, and also with the second adhesive.
    From GB 1 379 932 A an adhesive bond between a plate, in particular plasterboard and supports is known. A pressure-sensitive first adhesive and a second adhesive, which has a solidification mechanism, are applied in approximately equal thickness to the supports. When the 10 plate is applied to the supports, the first adhesive immediately fixes the plate.
    From DE 20 2007 001 775 1 U1 a thermally insulated wall is known, in which a hard foam panel is first attached to a wall element of a wall, for example a house wall. The attachment is done by gluing or doweling. Then a reinforcing mortar with internal mesh is applied to the outer surface of the rigid foam panels. The reinforcement mortar has to harden for approx. 1 week. Only then are veneer elements glued in the form of straps, for example clinker straps. These are generally glued and grouted individually after the cord.
    It is also known to use so-called aluminum composite panels as facade elements. Here, fasteners are first attached to the Wand25 element. Then the wall element is covered with an insulation layer, usually an insulation layer made of mineral fiber, e.g. Rock wool, covered. The aluminum composite panels are then attached to the support elements, this can also be done by gluing. The aluminum composite panels are not in contact with the layer of thermal insulation material. The fastening 30 of the aluminum composite panels is independent of the arrangement of the insulation layer made of thermal insulation material and also of whether this insulation layer is present at all or not. Such thermally insulated walls are known for example from DE 34 27 513 Al and DE 20 2008 001 893 Ul.
    The object of the invention is to provide a thermally insulated wall that can be created quickly, in particular in a significantly shorter time than a week
    BE2016 / 0008 does not require any special fasteners, in which a rear ventilation of the aluminum composite panels can be achieved, and which has a high strength.
    Furthermore, it is an object to specify a method for producing a thermally insulated wall which enables a thermally insulated wall to be built in a few days, possibly in one day, does not require any time-consuming preliminary work or intermediate work, can be carried out without special fastening elements and no waiting times between the individual Steps of construction required.
    This object is achieved in terms of the device by a thermally insulated wall with the features of claim 1. In this thermally insulated wall, a rigid foam panel is applied to the surface of the wall element. The hard foam sheet is glued on, for example. An adhesive is used that provides strength after a few minutes. The hard foam plate has an outer surface. An aluminum composite panel is applied to this outer surface. The aluminum composite panel has an inner surface that is immediately adjacent to the outer surface, it is at a distance of at least 1 mm from the outer surface. This creates a free space between the outer surface and the inner surface. This free space allows the arrangement to be ventilated, in particular the aluminum composite panel.
    The aluminum composite panel is connected to the rigid foam panel by two different adhesives. The first adhesive does not have a solidification mechanism, it only ensures the assembly strength. It is only through the second adhesive that the actually necessary strength of the connection between the aluminum composite panel and the rigid foam panel is achieved. The second adhesive has a solidification mechanism. This only starts after a certain time, for example 30 minutes or several hours. Since the first adhesive enables the aluminum composite panel to adhere and hold directly on the rigid foam panel, a second adhesive can be selected which is geared to the required final strength without having to reach this final strength particularly quickly. The two adhesives therefore contribute to the strength together. The first adhesive takes over the time in which the second adhesive has not yet hardened, after which the second adhesive is for the strength of the connection of the aluminum composite panel to the rigid foam panel
    BE2016 / 0008 responsible, he is preferably responsible for more than 90% for the final strength of the connection.
    The first adhesive is a solid. It has a thickness of at least one millimeter, preferably 2-4 mm. The second adhesive is a paste. It can be pressed and displaced as long as it has not yet hardened. The first adhesive determines the distance between the outer surface and the inner surface. The first adhesive has a maximum thickness of 8mm, in particular a maximum of 5mm.
    It has surprisingly been found that even with a narrow adhesive seam, a firm bond is achieved between the hard foam sheet and the adjacent aluminum composite sheet. Although the hard foam plate is very easy to injure locally and is therefore weak, it can easily be pierced with a screwdriver, for example, a long adhesive seam or a correspondingly large adhesive stain surprisingly enables high forces to be transmitted, so that the unit made of aluminum composite plate and hard foam plate has a high load capacity overall having. This applies in particular to load directions that run vertically. Over 80% of the inner surface can remain free of adhesives, in particular of the second adhesive, but a sufficiently firm connection is nevertheless achieved.
    In particular, it has been shown that firm connections to rigid foam panels can be produced with second adhesives in the form of industrial adhesives. To do this, it is sufficient to carry out the bonding in narrow, elongated strips; there may be larger gaps between the strips. The distances can be more than ten times the width of a narrow elongated strip of the adhesive.
    The first adhesive has a predetermined, constant thickness. This is achieved by using double-sided tape as the first adhesive. The first adhesive specifies the distance between the rigid foam panel and the aluminum composite panel.
    The second adhesive is pasty, it spreads when the aluminum composite panel is pressed against the hard foam panel, which makes the pressure movement
    BE2016 / 0008 limits that the thickness of the first adhesive is reached. Because of the first adhesive with constant thickness, i.e. e in the form of double-sided adhesive tape with a predetermined thickness, the distance between the outer surface of the rigid foam plate and the inner surface of the aluminum composite panel is always constant.
    An adhesive seam made from a second adhesive can be produced quickly and easily. A skilled worker can create several meters of adhesive seam in a short time. A common construction adhesive is used for this, which is applied cold. A polymer adhesive, for example TEC 7 from Novatech N.V., Oien, Belgium, is preferably used, which is applied with a pressure gun.
    In terms of the method, the object is achieved by a method having the features of claim 4. Hard foam panels are first applied to a wall element, for example an outer wall of a house, for example fixed by means of a chemical adhesive or a mortar. In this case, an agent is used which hardens relatively quickly, for example in 15 to 45 minutes, to such an extent that the rigid foam panels are sufficiently fastened to the wall element. Subsequently, a first adhesive and, on the other hand, a second adhesive are applied either to the outer surfaces of the rigid foam panels or to the inner surface of aluminum composite panels. The first adhesive is applied in first areas, the second adhesive is applied in second areas. These two areas can touch, but they are separate. The two adhesives are separated. There is preferably a free space between the two adhesives. The second adhesive is applied in a greater thickness than the first adhesive, preferably at least 1.5 times, preferably at least twice the thickness.
    The aluminum composite panels can now be applied to the outer surfaces. Liability is achieved immediately, this liability is achieved by the first adhesive. When the aluminum composite panels are pressed onto the outer surfaces, the second adhesive is pressed wide, it assumes the thickness specified by the first adhesive. Both adhesives are preferably applied in strips. The aluminum composite panels are fixed immediately after application. Adjacent panels can be applied immediately. They also no longer shift, existing joints remain constant. This is achieved with the first adhesive.
    BE2016 / 0008
    The first adhesive is designed so that the aluminum composite panels can be shifted to a certain extent in a plane that is parallel to the outer surface. This allows gap dimensions to be adjusted. This must be done before the second adhesive hardens.
    Both adhesives are designed so that on the one hand they have a high surface adhesion to the aluminum composite panels and on the other hand they have a high surface adhesion to the hard foam panels.
    It is known that rigid foam panels have an extremely low hardness. No strength is achieved with punctiform bonds because it is easy to tear a small area of foam material out of the surface of a rigid foam sheet. With a sufficiently extensive adhesive bond, which extends for example over 1 cm in width and 40 to 60 cm in length, however, sufficient strength is achieved that the necessary hold of the aluminum composite panels on the rigid foam panel is achieved.
    Aluminum composite panels are also referred to as aluminum composite panels and aluminum bond panels. They are layer plates. They usually consist of three layers. A middle layer is typically a layer of plastic, for example 2 to 5 mm thick. There are thin aluminum layers on their two main surfaces, which are typically 0.5 mm thick. They can be colored, anodized or otherwise treated.
    Hard foam sheets are sheets made of solidified foam, mostly polyvinyl chloride, polystyrene or polyurethane. They are characterized by high strength with low weight and good thermal insulation properties. The foam is preferably closed-cell. The foam sheets are finished products, they are prefabricated. They have a constant thickness. The thickness can be between 20 and 300 mm. Larger thicknesses are possible, e.g. up to 500 mm. Typical dimensions are 0.5 to 2 m high and 0.5 to 3 m wide
    Rigid foams have a relatively high resistance to deformation when subjected to pressure (DIN 7726). Their main characteristics are the
    BE2016 / 0008 outstandingly low heat conduction due to the insulation gases present in the closed cells and the ability to form solid bonds with almost all flexible or rigid cover layers. For rigid foams, reference is also made to DIN EN ISO 845. The rigid foams preferably have a density of 20 to 100 kg / m 3 , for example 20 to 50 kg / m 3 . Densities of 10 to 35 kg / m 3 can also be used.
    The invention is explained in more detail below on the basis of exemplary embodiments, with reference to the drawing. The exemplary embodiments of the invention are not to be understood as restrictive. The drawing shows:
    Fig.l: A perspective view of a corner of a wall element, on which hard foam panels and aluminum composite panels are applied, Fig. 2: a plan view of rigid foam panels on which three aluminum composite panels are applied, Fig. 3: 3 shows a sectional view through a thermally insulated wall with a wall element, a hard foam panel and an aluminum composite panel, each partially shown, Fig. 4: 3 shows a rear view of an aluminum composite panel, to which on the one hand a first adhesive is applied in first areas and on the other hand a second adhesive in second areas, Fig. 5: 4 in the viewing direction V and, Fig. 6: a sectional view through a rigid foam panel and two aluminum composite panels attached, each shown partially.
    Figure 1 shows a thermally insulated wall, it has a wall element 20, which is shown here as a 90 ° wall corner. The structure of the wall is not detailed, it is state of the art. It is e.g. around a concrete wall, a brick wall, or the like.
    BE2016 / 0008
    A plurality of hard foam panels 22 are applied, in particular glued, to the wall element 20. The prior art is also used here. The rigid foam panels all have the same format, including the same thickness. They are applied in such a way that no cross joints occur. This is advantageous, but need not be so.
    The rigid foam panels 22 are attached to the wall element 20 according to the prior art, e.g. with an adhesive or a mineral binder, for example mortar. Other mounting options are not excluded. The rigid foam panels 22 are attached to the surface 24 of the wall element 20.
    The hard foam panels 22 are fastened on the wall element 20 in such a way that their outer surfaces 26 are all in one plane if possible. This plane is called the plane of the outer surfaces. Aluminum composite panels 28 are glued to the outer surfaces 26. They are of the same format. As FIG. 1 shows, the format of the aluminum composite panels 28 is different from the format of the hard foam panels 22 and such that no joint between adjacent aluminum composite panels 28 is located directly above a joint between adjacent hard foam panels 22. This is beneficial. But it is not out of the question that joint is joint.
    The aluminum composite panels 28 are connected to the rigid foam panels 22 by two different adhesives. At the same time, a first adhesive 30 without a hardening mechanism and a second adhesive 32 with a hardening mechanism are used. These adhesives 30, 32 are either applied to an inner surface 34 of the aluminum composite panel 28, see FIG. 4, or they are applied to the outer surfaces 26. The adhesives 30, 32 are located in different areas. Only a very small part of the surface, either of the aluminum composite panel 28 or the rigid foam panels 22, is covered with adhesives. The first adhesive is located in first areas 36, the second adhesive is located in second areas 38. These areas 36, 38 do not overlap. They are preferably separated from one another by a free space 40. The first and second regions 36, 38 are preferably arranged in pairs, as shown in FIG. 4. There is between a pair of a first region 36 and a two
    BE2016 / 0008 th area 38 a first free space 40, which is at least four times as small as a second free space 41 to the next neighboring pair of another first area 36 and another second area 38.
    The first adhesive 30 has a predetermined thickness, see FIGS. 5 and 6. It is preferably a solid, in any case it can only be deformed with great effort. It determines the distance between the inner surface and the outer surface 26. This distance is at least 1 mm, preferably at least 2 mm. The upper limit is 10 mm, preferably 5 mm. Adhesive tapes from 3M under the name VHP (registered trademarks), for example, can be used as the first adhesive 30. Adhesive tapes that can be removed on both sides are also suitable. Adhesive tapes with PE foam backing or PU foam backing can also be used.
    The first adhesive 30 is preferably a pressure sensitive adhesive. By contact with the component to be glued, adhesion and strength of the connection are immediately achieved. The first adhesive 30 provides immediate hold, but only a limited hold. The actual strength of the connection between the hard foam plate 22 and the aluminum composite plate 28 is achieved by the second adhesive 32. This is applied pasty and only hardens after some time, for example after more than 10 or 20 minutes. Once it has hardened, the second adhesive 32 is practically exclusively responsible, in any case more than 90%, for the strength of the connection.
    The second adhesive 32 is applied in the form of a sausage, caterpillar or bead, this in a thickness that is significantly thicker than the predetermined thickness of the first adhesive. This is shown in FIG. 5. If the aluminum composite plate 28 according to FIGS. 4 and 5 is pressed onto a surface 26, namely until the first adhesive 30 comes into contact with the surface 24, the second adhesive 32 is laterally in the direction of the plane mentioned parallel to the outer surface 26, displaced and pressed wide. As a result, it is in flat contact with the outer surface 26.
    FIG. 2 shows that the aluminum composite panels 28 can also be laid in a cross joint. This has advantages for the overall architectural impression. In contrast, a cross joint is deliberately omitted in the embodiment according to FIG.
    BE2016 / 0008
    In Figure 1, an aluminum composite panel 28 is bent around the 90 ° edge. The outside aluminum layer is only curved, but has remained intact. In order to be able to carry out the bend, a V-shaped incision is made from the inner surface in the aluminum composite plate 28 in a known manner and according to the prior art, this incision goes as far as the outer aluminum layer, but not through this. This enables the shown bend.
    Figure 3 shows the connection. A hard foam plate 22 is applied to the wall element 20 with a suitable means 42. An aluminum composite plate 28 is applied to this in turn, by means of the second adhesive 32, which can only be seen in the sectional view here.
    FIG. 6 shows a section in another direction, specifically in the longitudinal direction of the caterpillar-shaped second adhesive and the strip-shaped first adhesive 30. Cavities 44 remain permanently free between these adhesives 30, 32. These are preferably not closed, but run through. The cavities 44 are preferably vertical. They preferably have a lower inlet and an upper outlet so that air can circulate in them.
    The first adhesive 30 preferably has a slidability in a plane parallel to the outer surface 26. This sliding ability is used in order to be able to align the aluminum composite panel 28 slightly after an aluminum composite panel 28 has been placed on an outer surface 26, for example in order to achieve a constant gap dimension. The first adhesive is preferably elastically displaceable. This sliding ability can be limited or limited to displacements of a few millimeters.
    As FIG. 6 in particular shows, the aluminum composite panels 28 are preferably laid in such a way that a gap 50 remains free between them. This also compensates for thermal expansion. The gap 50 can be bridged on the inside by an adhesive tape 52. During assembly, this is first applied to an aluminum composite panel 28, for example the lower aluminum composite panel 28 in FIG. 6 on the back. The application takes place with
    BE2016 / 0008 a free supernatant. If the upper aluminum composite plate 28 is now applied, it is pressed against the adhesive tape 52 and comes into contact with it. An adhesive tape 52 with a soft elastic foam backing can be used. As a result, the adhesive tape 52 presses against the inner surface 34.
    The outside of the aluminum composite panels 28 is the outer surface of the wall and thus of a building. The aluminum composite panels 28 protect the thermal insulation from the hard foam panels 22. The hard foam panels 22 support the aluminum composite panels 28.
    The applicant reserves the right to combine any features of the description and claims, including sub-features and sub-features, in any form.
