Figure 1 explains the attachment of a support element to a building wall 1. The carrier element consists of the insulation strip 2 and the carrier strip 3 and is fastened to the wall 1 using the dowel 4. It is advisable between the wall 1 and the insulation strip 2 and between the insulation strip 2 and the carrier strip 3 an adhesive layer 9 to install. The carrier strip 3 is to increase the strength with a Provide sheet 5. Fastening elements, preferably screws are inserted, which secure in this sheet Find a stop. For the insulation strip 2 is preferred Mineral fiber material is used, but it can also be rigid foam or other insulation materials are used. For the carrier strip 3 , organic and / or inorganic material, for example plate material Calcium silicate or cement-based material used.

FIG. 2 shows an embodiment in which the carrier strip 3 a dowel 4 and a composite fastening element 10 is integrated.

Figure 3 explains the force ratios for a load combination, which by the dead weight of the support system and the facade elements attached to it and occurs through hygrothermal effects. The figure shows the Effects of force, the particular advantage of the arrangement being evident, that the insulation strip 2 need not absorb tensile forces. The on force component D acting on it is determined by the compressive force Z generated by the dowel is transferred to the insulation strip, as well as by its own weight Q caused. The components therefore absorb the loads for which they are used are particularly suitable.

FIGS. 4 to 7 show embodiments for complete facade systems shown. For this purpose, plaster base panels 6 are applied to the base strips. The attachment of the plaster base panels 6 to the carrier strip 3 is by a Adhesive layer 9 and / or with screws 11 possible, so that in a simple manner secure attachment can be guaranteed. On the plaster base board 6 plasters 12 can be placed on the outside. Attaching ceramic elements, Glass cladding or facade panels made of metal and others commercially available facade panels are also possible.

It is also advantageous in this application that there is great freedom of color design consists. Dark coverings can also be applied because the thermal expansion is well controlled and therefore disturbing translucent joints can be avoided. Furthermore, the substructure through the simple possibility of designing it as a ventilated system especially for attaching coverings with high diffusion resistance suitable.

In the example explained here, the gaps are filled with the aid of insulation panels 7 which are glued and / or dowelled to the outer wall. This embodiment allows in the simplest way either to create rear-ventilated systems or to fill completely filled gaps only by selecting the thickness of the insulation board. The spaces can be filled both with insulation panels 7 and with roll material or by foaming in foamable materials. It is also possible to blow or fill in pourable insulation material. It is particularly advantageous that thick insulation layers can be produced, which is not practical when using wood as a composite support. Another advantage is that elastic fastening of the facade panels is achieved, so that no movement joints are required.
It is also advantageous that a sheet 5 can be attached to the carrier strip 3. FIG. 4 shows an embodiment in which the sheet is attached to the inside of the carrier strip 3 and comprises the end face of the carrier strip 3. Figures 5.1 and 5.2 show an embodiment in which the plate 5 is incorporated as an intermediate plate 8 in the carrier strip 3. The sheet 5 increases the security of screwing on the plaster base panels 6 because high forces can thus be absorbed.
Alternative designs are shown in FIG. 5.2. The intermediate plate 8 can be glued into a groove cut into the end face or can be completely integrated into the carrier strip 3. It is advantageous if the sheet is perforated in the central area.

The arrangement of the system on flat walls and in the corner area of two Wall surfaces are explained in FIGS. 6 and 7.

FIGS. 8 to 12 show application examples in which translucent thermal insulation has been integrated into a facade construction with the components.
In the arrangement shown in FIGS. 8 and 9, a translucent insulating material 16 is glued to the building wall 1 with black adhesive 17 between two vertical support elements. As a result, the wall acts as an absorber and can store the radiated thermal energy. A window is incorporated into the facade cladding to allow access to solar energy. To protect against excessive solar radiation, a movable sun protection device 19 was installed between the glass pane 20 forming the window and the translucent insulation material 16. The glass pane 20 is fastened by means of a rubber seal 22 and a metal frame 21. The arrangement of a translucent thermal insulation is particularly useful for systems that have a rear ventilation 18.

FIGS. 10 to 12 explain a further embodiment in which the Heat is generated with solar collectors 23. This is done on the outside a solar collector 23 integrated into the facade, which directly with one or with several radiators 25, which are located inside the building wall 1, connected is. Due to the warming that occurs as a result of solar radiation water circulation is effected. With the help of a valve 26 ensured that the water circulation only in the desired direction he follows. There is also a pressure compensation vessel 27 in the liquid circuit attached, with which the thermal expansion of the liquid is compensated. It is expedient here for the windproof wall penetration 28 routed connecting lines 24 as far as possible inside, thus a thermal bridging effect of the liquid in cases where none Sun exposure is present is minimized. To boost the to intensify heated liquid, it is appropriate to use two collectors to be arranged one above the other. It is of course also possible to put the collectors in one Include conventional system of heat generation: outside is a ceramic one Clothing 29 attached.

Figures 13 to 17 show the assembly process when attaching the facade. FIG. 13 shows a building wall 1 on which the support elements are laid in vertical strips and at a distance in the horizontal direction. The insulation panels 7 can then be fastened between the support elements according to FIG. 14.
FIG. 15 shows the facade view with plaster support panels 6 completely laid on the support elements.
Figure 16 shows the finished facade view with applied plaster system. In contrast to FIG. 15, a strip with an integrated translucent insulation layer 16 is shown in FIG. Deviating from FIG. 15, however, an integrated strip of transparent facade cladding with a translucent insulating material behind it according to FIG. 8 is shown.
FIG. 17 explains an example in which the carrier element is used for fastening a substructure for facade panels made of fiber cement. Sheet metal profiles or slats are fastened horizontally to the support elements, to which the facade panels are attached.

FIGS. 18 to 23 show further embodiments of the Support elements. FIG. 18 shows an element in which the Carrier strip is clad on the top with the sheet 5. This sheet, made made of stainless steel, galvanized and / or coated steel or made of aluminum, can enclose the carrier strip on the front side. Furthermore, a Projection of the sheet can be provided. This makes it possible to have facade panels with joints open above the support elements on the support elements Fasten. The support elements are thus part of the facade cladding used.

In Figure 19 is a support member which is reinforced by a Fabric 13 is shown. In the variant shown here, the Insulation strips 2 on two faces and the underside with applied or glued fabric 13 provided in the adhesive bond between Insulation 2 and carrier strip 3 is glued. They are different Alignment of the fabric structure possible. The fabric 13 envelops the Insulation strips 2 partially or completely and contributes to the forwarding of Forces. The side view shows different orientations of the fabric 13. It can be metal or glass mesh as well as any other inorganic and / or organic substances can be used.

In Figure 20, an embodiment is shown in which on two sides of the Insulation strip 2, a carrier strip 3 is arranged. This can be for one only mechanical fastening of the elements to the base of Be an advantage.

FIG. 21 shows an element according to FIG. 20, in which, in addition to Connection of the carrier strips 3 with the insulation strips 2 latticework 14 or frameworks are attached. This means that in the event that the insulation material only the attacking forces cannot pass on, an increase in load capacity be achieved. The latticework 14 made of metal, plastic or other organic and / or inorganic substances can consist of individual flat structures or be designed as a spatial framework. An attachment to the carrier strips 3 can by gluing, mechanical connections or - as in Figure 21 outlined - done by pouring into the carrier strip material.

FIG. 22 shows an element according to FIG. 20, which is attached to the substrate by means of dowels 4 is attached. The dowels 4, however, only capture the carrier strip on the wall side Third

The arrangement shown in FIG. 23 combines the embodiments according to 21 and 22. In addition, here is the wall-side carrier strip 3 not pulled all over the element, but covers it Element only partially, and as far as to accommodate the forwarded Forces from the dowels 4 is required. For fastening facade parts and the like can in the carrier strip 3 threaded sleeves 15th be arranged.
