• Rear-ventilated fagades typically comprise fagade cladding, a rear ventilation zone, insulation and a sub-structure which is fastened to an anchoring base.
• the anchoring base is usually a wall portion of a construction, for example masonry, generally an outer wall of the construction.
• the sub-structure generally consists of metal or wood or the like and comprises, for example, horizontally and vertically extending supporting rails and/or anchoring brackets, for example of metal, which are usually fastened in a regular pattern to the anchoring base.
• the insulation hereinunder referred to as the insulation layer, is often made of mineral wool, such as glass wool or rock wool, alternatively for example also of rigid foam slabs.
• the insulation layer is usually supplied in the form of individual insulation elements, such as rolls or slabs, and, at the building site, these are placed flat next to one another in the most gap-free manner possible to form the insulation layer.
• the fagade cladding is held at a distance from the insulation layer by means of a suitable supporting construction, thus forming the rear ventilation zone. Moisture can be reliably carried away via the rear ventilation gap owing to the physical separation between the insulation and the fagade cladding.
• fagade cladding For example, timber frameworks, natural stone, artificial stone or ceramic slabs, as well as glass or other generally rigid slab elements which protect the construction against the weather and the effects of impacts from the outside are suitable as fagade cladding.
• the fagade cladding is generally determined by ecological and aesthetic considerations.
• Dowels are typically inserted into the anchoring base when fastening the insulation elements in the anchoring base.
• a disadvantage of fastening the insulation layer using dowels becomes clear during mounting.
• a sub-structure in the form of anchoring brackets is fastened to the supporting anchoring base, this being done in a regular pattern.
• the anchoring brackets stick out perpendicularly from the anchoring base and serve as a holder for the fagade cladding.
• the insulation elements are slit, and the supporting regions of the anchoring brackets for the fagade cladding are inserted through the slits in the insulation elements and so these protrude out of the insulation layer.
• the mattress effect means that in particular the corners of the insulation elements often protrude with respect to the surface.
• the insulation elements are subject to outdoor exposure on the building site, in particular over a period until the fagade cladding has been attached.
• the mattress effect causes the lining fleece to tear off the insulation elements, especially at the corners. Depending on the duration of this action and on the wind strength, the fleece may tear off over half or even the whole surface.
• the corner regions can be levelled in order not to provide any additional contact surface for the wind and weather.
• FR 2557901 A1 discloses a fastening system for insulation material, in particular felt or insulation slabs on the inside of buildings, in particular in the region of a pitched roof.
• Anchoring elements are first fastened to a portion of a pitched roof or wall and small square plates with longitudinal or transverse slots are positioned in order to clamp the insulation material against the wall element.
• Flange regions with undercuts are provided on the small square plates and, in a further step, are bent up in order to fasten C-shaped profile rails to the beaded area thereof.
• Cladding slabs are fastened to the rear side of the C-shaped profile.
• the system is not suitable for use in rear- ventilated fagades since no air gap is formed, the C-shaped profile rails lie against the insulation material.

• cross-ties 40 in the form of Fig. 6.
• two cross-ties 40 are connected to each other in each case in the region of their fourth fastening portion 44 by means of the connector 50 illustrated by way of example in Fig. 8.
• the overall length of two connected cross-ties 40 is adjustable. In this way, very different distances between the anchoring brackets 20 can be bridged.
• the fourth fastening portions can comprise hooks (not illustrated) and so in each case two cross-ties 40 can be hooked to each other.
• the fourth fastening portion 44 of the cross-tie 40 can be fastened in each case by means of a connector 50, as illustrated for example in Fig. 8, to the second fastening portion 34 of the clamping plate 30.
• cross-ties 40 can be used which also have one or a plurality of second through-openings 442 in the third fastening portion 34 (not illustrated), wherein, in this case, the cross-ties 40 are connected to the clamping plates 30 by means of connectors 50 and the cross-ties 40 are connected between themselves by means of connectors 50.
• flexible cross-ties 40 can be used which comprise second through-openings 442 both in the third fastening portion 42 and also in the fourth fastening portion 44.
• the length of the cross-tie 40 can be adapted directly on the building site, in that it is cut or in some other way severed at its perforation 446.
• only one cross-tie 40 is required, which is connected at both ends in each case to a clamping plate 30 by means of a connector 50 in each case.
• cross-ties 40 can be used which have hooks 422 at both ends (not illustrated), wherein the hooks 422 engage into the first through- openings 342 of the clamping plates 30 and the hooks 422 of the two cross-ties are mutually hooked to each other.
• Fig. 13 shows an alternative image to Fig. 12, which can result after attaching the cross-ties 40 and clamping plates 30 on the anchoring brackets 20 when carrying out the method in accordance with the invention or when using the fastening set in accordance with the invention.
• the anchoring brackets 20 are disposed in a substantially regular grid pattern distributed horizontally and vertically over the wall portion 10. In each case, two anchoring brackets 20 are connected to each other diagonally, wherein the cross-ties 40 cross each other and form a net-like structure. This makes possible additional securing of the fastening arrangement.
• Fig. 14 shows an embodiment of the invention for fastening the insulation layer 12 to a wall portion 10 with a corner region 18.
• a first insulation element 14 ends flush with the wall portion 10 and a second insulation element 14 protrudes beyond the wall portion 10 and so the corner region 18 is replicated in its shape by the insulation elements 14.
• the insulation elements 14 in the corner region can also overlap into each other in another manner, thus, for example, a mitred flanged arrangement is troublesome but possible.
• the anchoring brackets 20 of the two wall portions 10 forming the corner region 18 are perpendicular to each other.
• the two anchoring brackets 20 with in this case three attachment points 28, one of which is an elongate hole, are provided with clamping plates 30.
• a first cross-tie 40 extends from the first clamping plate 30 where it engages with a first hook 422 into a through-opening 342.
• a second cross-tie 40 extends from the further clamping plate 30 where it likewise engages by means of a hook 422 into a through-opening 342.
• a third cross-tie 40 is fastened to the second cross-tie 40 by means of a connector 50.
• the third cross-tie 40 engages with its hook 422 into a through-opening 442 of the first cross-tie 40.
• the corner region has been bridged, purely by way of example exclusively, using the clamping plates 30, cross-ties 40 and connectors 50 illustrated in Figs. 4, 6 and 8.
• cross-ties 40 with hooks 422 at both ends or cross-ties 40 with through-openings 442 at both ends are possible as described above.
• Fig. 15 shows an alternative embodiment of the invention for fastening the insulation layer 12 to a wall portion 10 with a corner region 18.
• the anchoring brackets 20 of the two wall portions 10 forming the corner region 18 are also perpendicular to each other in this case.
• Both anchoring brackets 20 are provided with clamping plates 30.
• a single flexible cross-tie 40 which extends from the first clamping plate 30 to the second clamping plate 30, bridges the corner region 18.
• the cross-tie 40 is fastened at the ends to both clamping plates 30 by means of a connector 50.
• the cross-tie 40 is flexible and bends around the corner region. Alternatively, provision can be made that the cross-tie 40 is folded at the corner region 18 (not illustrated).
• FIG. 14 already shows the option of connecting cross-ties 40 only to cross-ties 40 and not to a clamping plate 30. It is obvious to a person skilled in the art that this option is naturally also available for the planar wall surface. Thus, where required, further cross-ties 40 connecting cross-ties 40 to each other can be integrated into a network.
