Description

[0001]

[0002] The invention relates to a fastening set for fastening an insulation layer to a wall portion of a construction, in particular for forming a rear-ventilated fagade, and a production method.

[0003] PRIOR ART

[0004] Constructions which are standardised in DIN 18516-1 | 2010-06 are referred to as a rear-ventilated fagade, curtain-wall fagade or even curtain-wall rear-ventilated fagade.

[0005] Rear-ventilated fagades typically comprise a 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 fastened in a regular pattern to the anchoring base. The position of the anchoring brackets is determined in particular by the structural calculation required for the covering.

[0006] 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 or crevice-free manner possible to form the insulation layer.

[0007] 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.

[0008] 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.

[0009] 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. Firstly, 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. After fastening the anchoring brackets, the insulation elements are slotted into place. 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. After mounting of the insulation elements, bores for the dowels are made in the anchoring base. The dowels are then driven in, wherein in particular in the case of soft bases, a uniform insertion depth is often not to be maintained. Above all, inexpensive dowels often have poorly functioning drive-in limitation or no such limitation. If a dowel is seated too deeply, this can be corrected only with difficulty. Particularly in the case of chamber stones, cross-pieces are often destroyed by the drilling of drill holes and the driving-in of dowels.

[0010] If the dowels are inserted too deeply, a mattress effect is produced on the insulation elements. The mattress effect means that in particular the corners of the insulation elements often protrude with respect to the surface. The insulation elements are subjected to outdoor exposure on the building site, and in addition particularly over a period until the fagade cladding has been attached. In the case of severe action by the wind, the mattress effect causes the lining fleece to tear off in 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.

[0011] By means of additional dowels at the corners, the corner regions can be levelled in order not to provide any additional contact surface for the wind and weather. However, this leads to an insulation element then having to be held by a plurality of dowels, which means a great deal of work having to be carried out at the building site.

[0012] Dowels with insertion depth limitation are also known but when these are used, drill holes are still also required and the mattress effects are also present in this case.

[0013] 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-profile rails lie on the insulation material.

[0014] DE 10 2022 134 713 A1 which forms the basis of the preamble of claim 1 discloses a fastening set having clamping plates and cross-ties which can be connected to one another by hooking and / or are designed to form a form-fitting connection or a frictional connection with one another, or additionally connectors for fastening a cross-tie to a clamping plate. The advantage of the set is that the insulation elements can be held in place by dowels not at specific points but rather in a linear manner. This means that joints between insulation elements or corner regions of insulation elements, at which they abut against one another, can be bridged, which, inter alia, also allows the system to be subjected to outdoor exposure. The set can even be adapted in part to the specific conditions on the building site. Hence, provision is made e.g. that a plurality of cross-ties can be connected to each other in order to bridge the distance between clamping plates to be connected or the anchoring brackets to be connected. However, this requires further set components in the form of connectors.

[0015] OBJECT OF THE INVENTION

[0016] The object of the invention is to provide a fastening set for fastening an insulation layer to a wall portion of a construction, which set is suitable in particular for the formation of a rear-ventilated fagade and facilitates mounting.

[0017] A further object of the invention is to provide a method for producing a rear-ventilated fagade which overcomes the disadvantages described above. DISCLOSURE OF THE INVENTION

[0018] The object is achieved by a fastening set and a method having the features of the independent claims. Advantageous embodiments are characterised by the features of the dependent claims.

[0019] In accordance with the invention, a fastening set for fastening an insulation layer to a wall portion of a construction, said wall portion being provided with a number of anchoring brackets, comprises at least one set of mounting plates and at least one punched tape. Provision is made that the mounting plates each have a two- dimensional base body with a fit-on portion for fitting onto an anchoring bracket, that the mounting plates also have at least one fastening element which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto, and that the punched tape is provided with at least one through-opening which is matched in terms of its size to the fastening element such that the punched tape can be fastened preferably loosely to the mounting plate by means of the fastening element.

[0020] Advantages of the invention

[0021] The fastening set makes it possible for the sub-structure of the curtain-wall fagade, in this case in the form of anchoring brackets, to be used both for holding the fagade cladding and for holding the insulation layer. The fastening set in accordance with the invention requires no drilling and placing of dowels in addition to the anchoring brackets. With the fastening set, the mattress effect is avoided and the insulation layer can fulfil its full function.

[0022] One advantage of the use of punched tapes is that the insulation elements are not held at specific points by dowels but rather are pressed in a planar or linear manner against the wall portion. The punched tapes can also be used advantageously for bridging joints between insulation elements. Preferably, the mounting plates are pressed into the insulation at least by the thickness of the two-dimensional base body of the mounting plate. This advantageously allows the punched tapes to lie directly against the insulation elements.

[0023] The fastening set additionally has the advantage that it provides a solution for a corner region of a construction. In the corner region, the anchoring bracket of a first wall portion is generally perpendicular to the anchoring bracket of a wall portion adjoining it. By means of mounting plates and punched tapes, it is possible to secure the corner region, as described in more detail below, in particular also with reference to the figures. The covering of the corner regions of the construction and the joints between the insulation elements by means of the punched tapes obviates shuddering noises to a significant extent in windy conditions. In particular, the solution in accordance with the invention makes it possible to hold the insulation elements in the corner region without dowels and to secure the lamination from becoming detached due to wind suction force. In an advantageous manner, in the case of punched tapes made of a flexible material, the corner region can be bridged e.g. by the punched tape being bent around the corner or folded. Therefore, fraying of fleece- reinforced insulation elements, for example, can also be avoided in the corner region of the building, which normally offers a particularly large contact surface for wind.

[0024] Therefore, the proposed solution also allows the insulation to be subjected to outdoor exposure at least temporarily.

[0025] The proposed solution is stable and universally applicable. Products from any manufacturer can be used as the insulation elements, in particular mineral wool, such as glass wool or rock wool, preferably in the form of mineral wool insulation slabs but also for example rigid foam slabs.

[0026] The invention is suited both to use in the modernisation of buildings and also when constructing new-builds. Mounting plate-base body

[0027] According to one embodiment, the two-dimensional base body of the mounting plate is substantially rectangular. Alternatively, however, other shapes are also possible, e.g. the two-dimensional base body can have a circular contour or generally a polygonal contour, e.g. a contour in the shape of a pentagon, hexagon or octagon.

[0028] The mounting plate base bodies can be manufactured from metal or as injection- moulded synthetic material parts, in particular PP, PE, PLA.

[0029] In the case of injection-moulded synthetic material parts, the two-dimensional base body can be designed with a plate thickness of 2 mm to 5 mm, preferably 3 mm to 4 mm. In the case of metal, in particular steel, the plate-shaped base body can be designed with a plate thickness of 0.5 to 0.8 mm, wherein this is not limiting to the invention.

[0030] The area of the two-dimensional base body can be e.g. 100 mm x 80 mm or 120 mm x 100 mm. In the case of a circular, two-dimensional base body, the preferred diameter is 10 to 50 cm, more preferably 15 to 30 cm, in particular 20 to 25 cm. The two-dimensional base body can have surfaces with material notches in order to save on material and reduce the weight.

[0031] According to one embodiment, provision is made that the fit-on portion of the mounting plate comprises at least one receiving slot which is dimensioned such that the mounting plate can be placed loosely on the anchoring bracket. When a mounting plate is placed loosely with its fit-on portion on an anchoring bracket, no form-fitting connection and / or frictional connection is formed.

[0032] However, in a preferred manner provision is made that the mounting plate is designed as a clamping plate. The fastening portion of the clamping plate is designed for forming a form-fitting connection and / or frictional connection to an anchoring bracket. In a preferred manner, provision is made that the fit-on portion of the mounting plate comprises at least one receiving slot which is dimensioned such that, when the mounting plate is placed on the anchoring bracket, a form-fitting connection and / or frictional connection is formed. A combination of a form-fitting connection and a frictional connection can also be present.

[0033] In this context, a form-fitting connection is understood to be mutual engagement of the connected parts, wherein the relative movement of the connected parts is limited or prevented. In this context, a frictional connection is understood to be a connection of the connected parts, in which the relative movement of the connected parts is limited or prevented by static friction.

[0034] The shape of the receiving slot is in principle arbitrary and for instance can be formed so as to taper from an edge of the mounting plate in the direction of a centre of the mounting plate or from a centre of the mounting plate in the direction of an edge of the mounting plate. Alternatively, the receiving slot can be formed having a constant width. The shape of the receiving slot, which is formed so as to taper from the centre of the mounting plate in the direction of an edge of the mounting plate, permits extensive adaptivity in relation to the width of the supporting region of the anchoring bracket and so there is compatibility with established anchoring bracket manufacturer systems.

[0035] Mounting plate-fastening elements

[0036] Furthermore, the mounting plate has at least one fastening element which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular to the two-dimensional base body.

[0037] The fastening element comprises e.g. a stem portion and a head portion, wherein at least the stem portion extends at least in sections from the two-dimensional base body in a direction perpendicular thereto. The head portion extends preferably at least in sections in a direction in parallel with the two-dimensional base body. Preferably, provision is made that the head portion and the stem portion are formed in one piece with one another.

[0038] According to one embodiment, the fastening element is mushroom head-shaped. The head portion is designed preferably as a spherical cap-shaped or hemispherical nub, which is advantageous but not limiting to the invention. Alternatively, the fastening element is designed having a cylindrical head portion.

[0039] Furthermore, in the case of a mushroom head-shaped fastening element or fastening element having a cylindrical head, provision is preferably made that the diameter of the through-opening of the punched tape is smaller than the diameter of the head portion but larger than the diameter of the stem portion. The diameter of the head portion is e.g. 20% to 100% larger than the diameter of the stem portion.

[0040] According to a further embodiment, the fastening element has a hook-like design and has a portion which extends preferably in a direction away from the edge of the mounting plate, e.g. a flat piece.

[0041] In a preferred manner, provision is made to manufacture the mounting plate as a punched piece from a metal strip, wherein a hook-like fastening element in the form of a tab is produced by means of a partial cut-out of the metal plate. The punched tab is simply bent e.g. upwards so as to form the angled flat piece which extends preferably in the direction away from the edge of the mounting plate. Alternatively, the punched tab is formed in such a way that a stem portion and a head portion are formed, wherein the stem portion extends at least in sections from the two- dimensional base body in a direction perpendicular thereto and the head portion has the angled flat piece which extends preferably in the direction away from the edge of the mounting plate.

[0042] Further alternatively, the fastening element can also be designed e.g. as a pin having a cylindrical stem portion without a specially configured head. In the embodiments described, the fastening element, in particular its stem section if present, preferably has a height in order to accommodate, preferably in loose manner, at least two punched tapes, preferably two to a maximum of three punched tapes, more preferably exactly two punched tapes.

[0043] Preferably, the mounting plates can be manufactured in one piece from metal or as injection-moulded synthetic material parts, in particular PP, PE, PLA.

[0044] Punched tapes

[0045] Within the scope of the present invention, punched tapes are understood to be longitudinally extended components which can include both rigid embodiments and, what is preferable, flexible embodiments. The punched tapes have a longitudinal extension and, by reason of their flatness, a certain stiffness at least in one dimension or in two dimensions, but can also be flexible and bendable in at least one dimension.

[0046] In the case of flexible punched tapes, they can preferably be bent or folded through at least 90° without plastic deformation. Flexible punched tapes preferably consist of a rollable or foldable material, e.g. in the form of a strip which can be unrolled.

[0047] The punched tape is designed preferably as a longitudinally extended flat component. The use of flat punched tapes leads to particularly low shuddering noises under the action of the wind. The punched tape preferably has a thickness of 0.6 mm to 5 mm, more preferably of 1 mm to 2 mm, particularly preferably of 1.2 mm.

[0048] The punched tape can be provided as a long tape in a dispenser and can be cut to length as required. For this purpose, cutting aids, such as marking lines or perforations, can be provided between individual through-openings.

[0049] The punched tape preferably has a plurality of through-openings. The through- openings are preferably arranged at regular intervals with respect to one another, in particular in a row along the longitudinal extension of the punched tape. The hole spacing is preferably 20 mm to 80 mm, particularly preferably 25 mm to 40 mm. Alternatively, it is possible for the punched tape to be provided with one or more through-openings when at the construction site.

[0050] The size of the through-openings is matched to the fastening element in such a way that the punched tape can be fastened to the mounting plate preferably in a loose manner by means of the fastening element.

[0051] Loose fastening of the punched tape to the mounting plate is understood to mean that a diameter of a through-opening of the punched tape is larger than a diameter of the fastening element, e.g. the stem portion of the fastening element. The diameter of the through-opening of the punched tape is e.g. up to 30%, preferably up to 20%, even more preferably up to 10% larger than the diameter of the fastening element, e.g. the stem portion of the fastening element.

[0052] The punched tape consists particularly preferably of an elastic material, in particular rubber, particularly preferably of EPDM, wherein the EPDM can also be fibre- reinforced. Above all, it is preferable if the material of the punched tape has such a degree of extensibility that it is possible to expand the through-openings manually using muscle power in order to force them over the head portions of the mushroom head-like fastening elements. Alternatively, the punched tape can also be manufactured from synthetic materials, such as PE, PET, PP or the like, composite materials or metal.

[0053] The punched tape is preferably extendible in such a manner that it can be extended up to 1.1 times, preferably up to 1.2 times, even more preferably up to 1.5 times its length without it becoming torn.

[0054] The hole spacing and the material are preferably selected such that the punched tape is designed to be extendible such that it is possible manually using muscle power to stretch a through-opening to the location of a second through-opening in the unstretched state without it becoming torn.

[0055] Alternatively, it is possible for the end side of the punched tape to be fitted with a head portion with fastening parts, such as a hook or the like, at the construction site in order to be fastened to the fastening element of the mounting plate.

[0056] Connectors for punched tapes

[0057] A plurality of punched tapes can also be fastened to one another. A plurality of punched tapes can be e.g. connected to one another in order to bridge the distance between anchoring brackets, which are to be connected, or to stabilise a cross pattern, as explained below with reference to figure 28.

[0058] The fastening set can thus also comprise connectors for fastening punched tapes to one another. The connectors for fastening punched tapes to one another can be designed similarly or differently, wherein it is preferable to have the similar design for all the connectors used for reasons of cost and sustainability.

[0059] A connector can be e.g. a stud, a screw, a bayonet pin, a set pin, a clamp, a band, a locking strap, a wire or a component with an adhesive portion or hook-and-loop fastener portion or the like. In the case of the design as a clamp, the connector can be provided with a spring element which keeps the punched tapes to be connected tensioned with respect to one another. In the case of the design as a stud, this stud can be in two parts, wherein the two parts can be connected e.g. using a rivet gun. A person skilled in the art is familiar with alternative ways of connecting punched tapes to one another. Within the scope of the invention, connections which can easily be dismantled and recycled are preferred.

[0060] The connectors can be manufactured as injection-moulded synthetic material parts, in particular PP, PE, PLA. Alternatively, metal parts or the like can be used. The proposed solution is sustainable if a suitable selection of materials is made, since it is suitable for entirely mono-material production. UV-stable materials are preferred, wherein e.g. a suitable UV additive can be added to the synthetic material. It is particularly advantageous that, by means of the proposed fastening set, substantially the same fire load as in the case of a known dowel solution is incorporated into the system.

[0061] Anti-slip device

[0062] In a preferred embodiment, the fastening set comprises an anti-slip device which secures the mounting plate to prevent it from slipping on the anchoring bracket.

[0063] The anti-slip device can be formed by bent portions in the region of the receiving slot of the mounting plate. The mounting plate, which is designed as a clamping plate, itself fulfils the function of protecting it against slipping on the anchoring bracket, e.g. by generating sufficient static friction, so that after the clamping plate has been fitted onto the anchoring bracket and pressed into the insulation layer, the clamping plate is prevented from snapping back or slipping.

[0064] The bent portions in the region of the receiving slot can extend starting from the two- dimensional base body in the same direction as the fastening elements or in the opposite direction.

[0065] The bent portions in the region of the receiving slot can be formed e.g. by deformation of the two-dimensional base body, in particular if it consists of metal.

[0066] Alternatively, the anti-slip device can be based on the fact that an additional part or adhesive material is provided in the contact region of the mounting plate and the anchoring bracket, which secures the mounting plate to prevent it from slipping on the anchoring bracket. The protection against slipping can be achieved e.g. by producing sufficient static friction, e.g. by connecting, e.g. bracing the mounting plate and the anchoring bracket against one another or by bonding them together. However, the protection against slipping can also be implemented by supporting the additional part against structural components provided on the mounting plate and / or anchoring bracket, such as protrusions, lips, lugs, merlons, walls of notches and the like. For example, the additional part is wedged against the mounting plate and / or anchoring bracket. Combinations of high static friction, e.g.in contact with the mounting plate, and support, e.g. against a structural component of the anchoring bracket, or vice versa, are also possible. Even further alternatively, the protection to prevent slipping can be implemented by virtue of the fact that the additional part is placed in front of the mounting plate in order to prevent the mounting plate from slipping.

[0067] The additional part can be formed by means of a punched tape. The punched tape can be designed as described above and in particular can consist of a separated, e.g. cut-off portion of the punched tape, which is provided in the fastening set for connecting the mounting plates. The punched tape can be fastened e.g. to the fastening elements of the mounting plate and / or the anchoring bracket in order to brace them against one another. Alternatively, in the case of a punched tape made of a rubber material, e.g. EPDM, the punched tape can be inserted between the anchoring bracket and the mounting plate in order to increase the static friction between the anchoring bracket and the mounting plate. Even further alternatively, the punched tape can be wound fixedly around the anchoring bracket in front of the mounting plate in order to prevent the mounting plate from slipping.

[0068] Alternatively, the anti-slip device can also be provided in the form of further individual parts in the set, which are referred to below as anti-slip parts.

[0069] The anti-slip part can be a sealing or adhesive tape which consists e.g. of a rubber material, such as EPDM and forms the additional part described above. The sealing or adhesive tape can be used between the anchoring bracket and the mounting plate in order to increase the static friction between the anchoring bracket and the mounting plate. Alternatively, the sealing or adhesive tape can be wound fixedly around the anchoring bracket in front of the mounting plate in order to prevent the mounting plate from slipping. Alternatively or in addition, the anti-slip part can be a cap or a buckle. The cap or buckle can be used between the anchoring bracket and the mounting plate in order to increase the static friction between the anchoring bracket and the mounting plate. Alternatively, the cap or buckle can be placed in front of the mounting plate in order to prevent the mounting plate from slipping.

[0070] In one embodiment, the anti-slip part is formed as a preferably metallic spring element. For example, provision can be made that the spring element has a slot which is matched to a receiving slot of the mounting plate or the dimensions of the anchoring bracket such that the spring element prevents the mounting plate from snapping back or slipping after the mounting plate has been fitted onto the anchoring bracket and pressed into the insulation layer. The anti-slip device can be based on high static friction and / or support, as described above.

[0071] Even further alternatively, such a preferably metallic spring element can be connected to the mounting plate to form a composite component. The anti-slip device can also comprise a two-part spring element which is connected to the mounting plate to form a composite component. The composite component can be manufactured by subsequently connecting the parts, e.g. by riveting, or by extrusion coating or by another suitable way of embedding the spring element into the mounting plate.

[0072] Anchoring brackets

[0073] The fastening set can also comprise the anchoring brackets. Components known to a person skilled in the art are suitable as the anchoring brackets, in particular metal or synthetic material components which, on the one hand, can be fastened to the anchoring base and, on the other hand, comprise a supporting region which preferably protrudes perpendicularly out of the anchoring base and serves for fastening of the fagade cladding. The anchoring brackets can be designed in one piece, e.g. as L-profiles, or in multiple pieces, e.g. with an anchoring plate for dowelling to the wall portion and a support arm fastened thereto. The anchoring plate is preferably designed as an L-profile having a foot region, which can be fastened to the wall region, and a supporting region which extends perpendicularly thereto. The anchoring bracket having an L-profile can be designed in an advantageous manner simply as a punched profile.

[0074] In one advantageous embodiment, the anchoring brackets have a toothed profile which is matched to the geometric dimensions of the mounting plate, in particular to the thickness of the mounting plate, and so the mounting plate can be placed in a form-fitting manner on the anchoring bracket. In this embodiment, the mounting plate can advantageously be locked on the anchoring bracket at defined distances perpendicularly to the wall plane. For this purpose, the toothed profile can include a sequence of merlons, in particular also in order to be able to clamp insulation materials of different thicknesses against the wall portion by means of the mounting plate. The toothed profile of the anchoring bracket can be designed in an advantageous manner simply as a punched profile.

[0075] In one advantageous development, the mounting plate can comprise, in particular in the region of the receiving slot, a placement notch which is adapted to the anchoring bracket and which is matched to the notches of the toothed profile of the anchoring brackets and so it can be brought mechanically into engagement therewith.

[0076] Instead of simple merlons, the toothed profile of the anchoring bracket can also have a more complex design. For example, a toothed profile can be provided having hooklike merlons, at the upper end of which lugs oriented in the direction of the supporting portion protrude. The complex toothed profile of the anchoring bracket can also be designed in an advantageous manner simply as a punched profile.

[0077] In one advantageous development, the mounting plate can have a slip-in window which is adapted to the anchoring bracket and is matched to the size of the hook-like merlons of the anchoring bracket, so that the lugs of the toothed profile can each be mechanically engaged with the slip-in window. If the lugs and the slip-in window are dimensioned accordingly, the mounting plate can be held on the anchoring bracket without slipping, without lifting off and without tilting.

[0078] Method

[0079] The invention also includes a use of one of the described fastening sets to produce or to construct a rear-ventilated fagade.

[0080] In the case of a method in accordance with the invention for producing a rear- ventilated fagade, the following steps are provided: a) fastening anchoring brackets to a wall portion of a construction, b) attaching insulation elements to at least a part of the wall portion in order to construct an insulation layer, wherein at least some anchoring brackets protrude with supporting regions out of the insulation layer, c) fitting mounting plates on the supporting regions of the anchoring brackets, d) optionally securing the mounting plates to prevent them from slipping on the anchoring brackets, e) optionally repeating steps b), c) and d), f) fitting at least one punched tape onto at least one fastening element of a first mounting plate, g) tensioning the punched tape over one or more insulation elements in order to hold the insulation layer against the wall portion, and h) fitting the punched tape onto at least one fastening element of a second mounting plate, g) optionally repeating steps f) to h) or steps b) to h), and h) attaching a fagade cladding to the anchoring brackets.

[0081] Preferably, the method is carried out using one of the fastening sets described above, i.e. comprising a set of mounting plates and at least one punched tape, and optionally anchoring brackets, connectors and / or anti-slip elements which are designed as described above. The features which are described in connection with the components of the fastening set should therefore also be regarded as disclosed in connection with the method.

[0082] Therefore, the mounting plates preferably each have a two-dimensional base body with a fit-on portion for fitting onto an anchoring bracket and fastening elements which extend from the two-dimensional base body at least in sections in a direction perpendicular thereto.

[0083] Some, or preferably all, of the anchoring brackets which are fastened to the anchoring base in order to fasten the fagade cladding are thus provided with mounting plates, wherein in each case a mounting plate is placed with its fit-on portion onto an anchoring bracket provisionally in a loose manner or with a formfitting connection and / or frictional connection. Within the scope of the present disclosure, the phrase “provisionally in a loose manner” refers to a state which is not intended to be permanent and which is achieved by avoiding a form-fitting connection and / or frictional connection.

[0084] Preferably, in step c) the mounting plates are pressed into the insulation approximately by the thickness of the two-dimensional base body of the mounting plate. At least some of the mounting plates are then connected to one another in each case by means of punched tapes. After attachment, the punched tapes preferably lie directly on the insulation layer.

[0085] In step d), provision is preferably made to secure the mounting plate to prevent it from slipping on the anchoring bracket. This advantageously makes it possible for the mounting plate to be pressed a short distance into the insulation element and to be locked in place so that after attachment the punched tape lies permanently in a planar manner on the insulation plane. The mounting plate is fastened, wedged, braced or similar to the anchoring bracket by means of the anti-slip device. If the receiving slot is of a suitable shape and size or if the anti-slip device is already integrated into the mounting plate, e.g. by means of bent portions in the region of the receiving slot, the anti-slip device can already be provided when said mounting plate is fitted on in step c).

[0086] In step d) of providing anti-slip protection, provision can be made to introduce a punched tape in the contact region between the anchoring bracket and the mounting plate in order to generate a static friction between the anchor bracket and the mounting plate. Alternatively, it is also possible to use an anti-slip element, such as e.g. a sealing or adhesive tape, a cap or a buckle. Alternatively, the punched tape, the sealing or adhesive tape, the cap or the buckle can also be placed in front of the mounting plate in order to prevent the mounting plate from slipping.

[0087] In order to provide anti-slip protection, the punched tape can also be tensioned over two or more fastening elements of the mounting plate, with the anchoring bracket being braced with the mounting plate.

[0088] Even further alternatively, the anti-slip device can be provided in the form of a preferably metallic spring element which can be provided in the fastening set as an individual part or as a composite component with the mounting plate. The spring element likewise has a slot which is matched to the receiving slot of the mounting plate or the dimensions of the anchoring bracket such that it prevents the mounting plate from snapping back or slipping after the mounting plate has been fitted onto the anchoring bracket and pressed into the insulation layer.

[0089] As a further optional, additional method step, provision can be made to secure the mounting plate to prevent it from lifting off from the anchoring bracket. For example, a punched tape can be used to be tensioned over two fastening elements so that the mounting plate is tensioned against the anchoring bracket. Alternatively or in addition thereto, provision can be made to position some mounting plates on the anchoring brackets in the opposite direction to other mounting plates and to brace them against one another by means of punched tapes. The use of the punched tape additionally as an anti-lift device or anti-slip device has the advantage that the set has very few individual parts.

[0090] In the case of the method in accordance with the invention, it is ideally possible to entirely dispense with dowels and attachment thereof to the anchoring base. Anchoring brackets are merely fastened to the wall portion, wherein at the same time the anchoring brackets preferably have the function of supporting the fagade cladding. Therefore, the proposed solution has the advantage that no dust and no noise are produced when attaching the fastening set. Thus, advantageously, no special tool, such as a drilling machine or hammer, is required and mounting is possible irrespective of the material of the wall portion of the building.

[0091] Particularly rapid mounting of the system is advantageously the result. By reason of the fact that the insulation is attached in sections, i.e. the insulation elements are mounted in a step by step procedure, the method allows work to be carried out visually.

[0092] Within the scope of the method in accordance with the invention, provision can advantageously be made for using the punched tapes only in regions on the wall portion. Within the scope of the invention, it is thus possible to also make different regions of the wall portions differently, specifically with or without punched tapes. By virtue of the mounting plates for holding the insulation elements, no punched tapes at all are required in the middle regions, since the number of dowels required for practical purposes per square meter (mounting plates in this case) is already achieved. The system using the punched tapes is advantageously used in regions, in particular in the edge region of the rear-ventilated fagade and / or in the corner region. Thus, in one embodiment, in one region, in particular an edge region, the insulation elements are held against the wall portion by means of punched tapes, which are connected to mounting plates, and in another region, in particular a middle wall region, they are held only by means of mounting plates. Depending on the building height and wind loading zone, the number of punched tapes can be varied in order to ensure that the insulation elements are secured.

[0093] The method in accordance with the invention has the further advantage that the insulation elements are not fixedly clamped to the wall portion when, for example, dowels are driven in too deeply. On the contrary, the mounting plates are fastened on the supporting regions of the anchoring brackets preferably in a position- correctable manner so as to obviate the mattress effect.

[0094] Advantageously and preferably, the punched tapes can be provided in a dispenser and cut to length on site during installation. This means that in each case a punched tape can be used in order to connect the mounting plates to one another. Alternatively, e.g. in the case of punched tapes having a prefabricated length dimension, provision can be made that a plurality of punched tapes are used in order to bridge distances between mounting plates which are to be connected. A connector can preferably be used for this purpose. The method can thus advantageously be carried out irrespective of the specific distance of the anchoring brackets from each other. The position of the anchoring brackets can be determined exclusively by the necessary structural calculation and the material use and / or costs thereof.

[0095] With the method in accordance with the invention, a corner region of the wall portion of the construction can be easily bridged and secured by means of the punched tapes. In an advantageous manner, in the case of punched tapes made of a flexible material, the corner region can be bridged e.g. by the punched tapes being bent around the corner or folded.

[0096] The invention also relates to a rear-ventilated fagade which has been produced using one of the described methods and / or by means of one of the described fastening sets.

[0125] EMBODIMENTS OF THE INVENTION

[0126] Figure 1 shows an exemplified dowel pattern which results when the insulation elements 14 are being fastened to the anchoring base according to the prior art. The insulation layer 12 is in this case formed from a plurality of insulation elements 14 disposed offset with respect to each other, for example, mineral wool insulation slabs. Each insulation element 14 is fixedly held on the anchoring base, for example masonry, by two centrally placed dowels 16. In the region of the corners of the insulation elements 14 further dowels 16 are inserted in order to protect the corners.

[0127] Figure 2 shows an exemplified photograph of a building with an insulation layer fastened by means of dowels, with storm damage. Fleece-reinforced mineral wool was used in this case. The black fleece is ripped off at many points. In particular, the corners are frayed and damaged by outdoor exposure and after the storm. In this case, the dowels are inserted too deeply and so a mattress effect is produced on the insulation elements. The mattress effect means that the corners of the insulation elements protrude with respect to the surface. By means of additional dowels at the corners, as shown in figure 1 , the corner regions can be held back in order not to provide an additional contact surface for the wind and weather. In the mode of construction illustrated in figure 1 , it is necessary for each insulation element 14 to be held by means of at least four dowels 16, which involves a considerable amount of work.

[0128] Figure 3 shows a mounting plate 30 which is suitable for use in a fastening set according to one embodiment of the invention. The mounting plate 30 comprises a two-dimensional base body 34 which has e.g. a surface area of 100 mm x 80 mm and a plate thickness of 3 mm. The two-dimensional base body 34 is e.g. an injection-moulded synthetic material part.

[0129] The two-dimensional base body 34 comprises a fit-on portion 32 which is designed as a tapered receiving slot 322 which extends in a manner tapering from a middle 38 of the mounting plate 30 towards an edge of the mounting plate 30. The receiving slot 322 is formed in such a way that the mounting plate 30 can be fitted on an anchoring bracket 20 (see e.g. figure 22) and fixedly clamped.

[0130] The use of the tapered receiving slot 322 makes the mounting plate 30 adaptive in particular in relation to the use with anchoring brackets 20 from any manufacturer.

[0131] In the illustrated embodiment, the mounting plate 30 is substantially rectangular with rounded corners, wherein the shape facilitates handling thereof and keeps the risk of injury for the user low. Alternatively, circular mounting plates 30 (see figure 8) or even other geometries are covered by the invention, e.g. with a circular or polygonal contour.

[0132] A central opening 324 is formed in the middle of the mounting plate 30. In the illustrated embodiment, four fastening elements 342 are provided around the central opening 324, which is not limiting to the invention. A radial arrangement of the fastening elements 342 around the central opening 324 is advantageous insofar as it permits in this case attachment options for punched tapes 40 in different directions away from the central opening 324.

[0133] Figure 4 shows a further embodiment of a mounting plate 30 which is suitable for use in a fastening set according to one embodiment of the invention.

[0134] In contrast to the embodiment described with reference to figure 3, the mounting plate 30 comprises a fit-on portion 32 which is formed as a straight receiving slot 326 which extends with parallel limbs with a constant width from the edge of the mounting plate 30 towards the middle 38 of the mounting plate 30. The straight receiving slot 326 is formed in such a way that the mounting plate 30 can be fitted on an anchoring bracket 20 and fixedly clamped.

[0135] Above the central opening 324, which is advantageous in this case but not necessarily provided, is a placement notch 328 which is matched to a toothed profile 242 of the anchoring bracket 20 illustrated in figure 22. By reason of the form-fitting connection of the placement notch 328 with the toothed profile 242, it is ensured that the mounting plate 30 is seated securely on the anchoring bracket 20. The further statements relating to the embodiment described in figure 3 also apply to the embodiment illustrated in figure 4, wherein no repeated description will be given.

[0136] Figure 5 shows a further embodiment of a mounting plate 30 which is suitable for use in a fastening set according to one embodiment of the invention. The mounting plate 30 in the embodiment shown in figure 5 can be manufactured as a punched piece of metal, wherein the fastening elements 342 are produced in the form of tabs by means of partial cut-outs of the metal plate. The tabs can then be formed into hooks, e.g. bent upwards, e.g. in the manner shown in figure 11 or 12.

[0137] Figure 6 shows a perspective view of a mounting plate 30 according to a further embodiment of the invention. The fastening elements 342 are formed in this case having a stem portion 62 and a head portion 60, each in the form of a cylinder. The fastening elements 342 extend starting from the two-dimensional base body 34 in a direction perpendicular thereto.

[0138] Figure 7 shows a perspective view of a mounting plate 30 according to a further embodiment of the invention. As in figure 6, the fastening elements 342 are formed having a stem portion 62 and a head portion 60, each in the form of a cylinder. In addition, material notches 344 are illustrated schematically in the two-dimensional base body 34, the size and number of said notches can be dimensioned such that as much material as possible is saved while maintaining sufficient stability for the desired functionality and the weight of the mounting plate 30 is reduced.

[0139] The design of the mounting plate 30 is compatible in particular with the embodiment of the anchoring bracket in figures 23 and 24. In contrast to the mounting plate 30 described with reference to figure 6, this additionally comprises, above the central opening 324, a slip-in window 325 which is matched to the size of a lug 243 in the toothed profile 242 of the anchoring bracket 20. The mounting plate 30 is fitted onto the anchoring bracket 20 and is pressed into the corresponding insulation layer 12. A lug 243 thereby engages into the slip-in window 325. The elastic spring-back of the insulation material pushes the mounting plate 30 out slightly, whereby the web located between the slip-in window 325 and the central opening 324 is pushed into the undercut 245 of the toothed profile 242. In an advantageous manner, the mounting plate 30 is countersunk flush with adjacent areas in the insulation layer 12 after spring-back. If the lugs 243 and the slip-in window 325 are dimensioned accordingly, the mounting plate 30 can be held on the anchoring bracket 20 without slipping, without lifting off and also without tilting.

[0140] Figure 8 shows a perspective view of a further embodiment of a mounting plate 30. In this case, the two-dimensional base body 34 is circular and has e.g. a diameter of 25 cm and a plate thickness of 0.6 mm.

[0141] In this embodiment, the two-dimensional base body 34 comprises a straight receiving slot 326 as a fastening portion 32 which extends starting from an edge of the two- dimensional base body 34 to the middle 38. Purely by way of example, the mounting plate 30 comprises six material notches 344 which are delimited by webs 346 which extend from an annular outer edge 348 of the two-dimensional base body 34 to the middle 38. Tab-like fastening elements 342 are located circumferentially on the two- dimensional base body 34 and can be configured in the manner illustrated in figures 11 or 12. In particular, the fastening elements 342 can be produced from partial cutouts 64 of the two-dimensional base body 34. The straight receiving slot 326 is surrounded on the edge side by bent portions 328 which form an anti-slip device when the mounting plate 30 is placed on the anchoring bracket 20. When the mounting plate 30 is placed on the anchoring bracket 20, the mounting plate 30 is pressed sufficiently deeply into the insulation layer 12. The bent form of the bent portions 328 means that the elastic spring-back is resisted by the insulation material.

[0142] The bent portions 328 and the fastening elements 342 can extend starting from the two-dimensional base body 34 in opposite directions, as illustrated, or in the same direction (not illustrated).

[0143] Figure 9 shows a side sectional view of a part of a mounting plate 30 according to one embodiment of the invention.

[0144] A portion of the two-dimensional base body 34 is illustrated, to which a fastening element 342 for fastening a punched tape 40 to the mounting plate 30 is attached in one piece. The fastening element 342 extends starting from the two-dimensional base body 34 in a perpendicular direction thereto.

[0145] In the illustrated embodiment, the fastening element 342 is designed in the form of a mushroom head. It has a preferably cylindrical stem portion 62 and a preferably rotationally symmetrical head portion 60, wherein the head portion 60 is designed in this case by way of example as a hemispherical nub. In alternative embodiments (not illustrated), the head portion 60 can be formed as a spherical cap (or, in other words, as a spherical segment), e.g. for reasons of material savings or improved handling capability.

[0146] The stem portion 62 has a height h and a diameter d. The height h is adapted in order to receive up to two or up to three punched tapes 40. The diameter d of the stem portion 62 is e.g. 6 mm. The head portion 60 has e.g. a diameter dP of 9 mm. A punched tape 40 made of a rubber material, e.g. EPDM, which is provided with through-openings 442 having a diameter of e.g. 7 mm can be fastened to the fastening element 342 by manually elastically expanding a through-opening 442 and forcing it over the head portion 60. The elastic material of the punched tape 40 then contracts after the head portion 60 has been overcome and thus the punched tape 40 is connected loosely together with the stem portion 62 of the mounting plate 30 by reason of the advantageously selected sizes of the diameters. Alternatively, provision can be made that one, two or more punched tapes 40 do not lie loosely between the head portion 60 and the two-dimensional base body 34, but instead are clamped.

[0147] After the punched tape 40 has also been fastened in such a manner on the other side to a further mounting plate 30, two mounting plates 30 are connected to one another via the punched tape 40.

[0148] Figure 10 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0149] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a punched tape 40 to the mounting plate 30 is attached in one piece.

[0150] The fastening element 342 extends in turn with a preferably cylindrical stem portion 62 starting from the two-dimensional base body 34 in a perpendicular direction thereto. In this case, the fastening element 342 is designed in the manner of a hook. It has a head portion 60 in the form of an angle-bent flat piece.

[0151] The height h and the diameter d of the stem portion 62 can be designed as in the embodiment described above with reference to figure 7. The head portion 60 has e.g. a length dP of 9 mm. The punched tape 40 made of a rubber material, e.g. EPDM, which is provided with through-openings 442 having a diameter of e.g. 7 mm can be fastened to the fastening element 342 by threading the head portion 60 in one of the through- openings 442. After the head portion 60 has been overcome, the punched tape 40 hangs loosely on the stem portion 62 of the mounting plate 30 with advantageously selected diameter ratios.

[0152] Figure 11 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0153] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a punched tape 40 to the mounting plate 30 is attached in one piece.

[0154] The mounting plate 30 in the embodiment shown in figure 11 can be manufactured as a punched piece of metal, wherein the fastening element 342 is produced in the form of a tab by means of a partial cut-out 64 of the metal plate, see also figure 5. The punched tab was then deformed in the manner of a hook, thus forming the stem portion 62 and the head portion 60. The head portion 62 and the stem portion 62 can be dimensioned in the manner described with reference to figure 10.

[0155] Figure 12 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0156] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a punched tape 40 to the mounting plate 30 is attached in one piece.

[0157] The mounting plate 30 in the embodiment shown in figure 12 can be manufactured as a punched piece of metal, wherein the fastening element 342 is produced in the form of a tab by means of a partial cut-out 64 of the metal plate, see also figure 5. The punched tab was then deformed in the manner of a hook, thus forming a fastening tab 61 .

[0158] Figure 13 shows a perspective view of a mounting plate 30 with an anti-slip device according to an alternative embodiment. The fastening set comprises an additional component in the form of a spring element 70. In this case, the spring element 70 is formed by way of example by means of a bent metal sheet which is provided on a longitudinal side with a central slot 72 which is matched to the width of the anchoring bracket 20. After the mounting plate 30 is placed onto the anchoring bracket 20, the spring element 70 is placed onto the anchoring bracket 20 and is pressed with the mounting plate 30 sufficiently deeply into the insulation layer 12. The bent form of the spring element 70 results in a tunnel-shaped gap 71 remaining between the spring element 70 and the mounting plate 30. The elastic spring-back of the insulation material generates pressure onto the mounting plate 30, which pressure is, however, resisted by the spring element 70 secured against the anchoring bracket 20. The spring element 70 can also extend more deeply than illustrated in the drawings over the height of the anchoring bracket 20.

[0159] Figure 14 shows a perspective view of a mounting plate 30 having an anti-slip device according to a further embodiment. The fastening set comprises an additional component in the form of a two-part spring element 74. Both parts of the spring element 74 are connected to the mounting plate 30 to form a composite component, and moreover by means of fastening rivets 76, but this is purely by way of example. Both parts of the spring element 74 are formed from bent metal sheets. They are fastened to the mounting plate 30 such that in each case one limb protrudes in the shape of a lip from the mounting plate 30, wherein the two limbs form a gap therebetween which is matched to the thickness of the anchoring bracket 20. A gap 71 is likewise located between the arcuate protruding limbs and the mounting plate 30.

[0160] When the mounting plate 30 is placed onto the anchoring bracket 20, the spring element 74 is placed onto the anchoring bracket 20 at the same time. The bent form of the spring element 74 means that, when the mounting plate 30 is pressed into the insulation material, the elastic spring-back of the insulation material generates pressure onto the mounting plate 30, but this is resisted by the spring element 74.

[0161] Figure 15 shows a side sectional view of the mounting plate 30 with the anti-slip device of figure 13. The spring element 70 was fitted onto the anchoring bracket 20 in such a way that the mounting plate 30 is pressed into the insulation layer 12 by the amount of the thickness of the two-dimensional base body 34 of the mounting plate 30. The spring element 70 prevents the mounting plate 30 from snapping back on the anchoring bracket 20. After the punched tape (not illustrated here, cf. figure 19 ff.) has been fitted onto the fastening element 342 of the mounting plate 30, the punched tape can be tensioned over one or more insulation elements of the insulation layer 12, wherein it lies in a planar manner on the insulation layer 12.

[0162] Figure 16 shows a side sectional view of the mounting plate 30 with an alternative anti-slip device. A buckle 73 (a fixed additional part, or even a sealing tape, a portion of the punched tape or the like) has been attached around the anchoring bracket 20 in such a way that the mounting plate 30 is pressed into the insulation layer 12 by the amount of the thickness of the two-dimensional base body 34 of the mounting plate 30 and the mounting plate 30 is prevented from snapping back on the anchoring bracket 20.

[0163] Figure 17 shows a side sectional view of the mounting plate 30 with another alternative anti-slip device. In this case, a wedge 75 (a fixed additional part, or e.g. even a portion of the punched tape or the like) was inserted into the gap between the anchoring bracket 20 and mounting plate 30, the mounting plate 30 is pressed into the insulation layer 12 and the snap-back is prevented.

[0164] Figure 18 shows a plan view of a mounting plate 30 which is protected against being lifted off. After the mounting plate 30 has been placed onto the anchoring bracket 20, a punched tape 40 is cut to size and fastened to two fastening elements 342 in such a manner that the mounting plate 30 is tensioned against the anchoring bracket 20. This prevents the mounting plate 30 from slipping on and at the same time from being lifted off from the anchoring bracket 20.

[0165] Figure 19 and figure 20 show alternative embodiments of a punched tape 40 which are each suitable for being used in a fastening set in accordance with the invention.

[0166] The punched tape 40 is e.g. a perforated rubber strip made of EPDM having a thickness of 1 .2 mm and comprises in each case a plurality of through-openings 442 which in this case are arranged, by way of example but in a manner not limiting to the invention, in one line and equidistantly from one another at a distance of 30 mm with respect to one another.

[0167] The illustrated embodiments of the punched tape 40 in figure 19 and figure 20 are, in each case, a punched tape 40 made of a flexible material which has a longitudinal extension and sufficient stiffness in one or two dimensions but is flexible and bendable at least in one dimension.

[0168] The punched tape 40 in figure 19 and figure 20 is provided in each case with a plurality of through-openings 442 which are spaced apart from each other by cutting marks or perforations 446 which are provided optionally but preferably. The flexible punched tape 40 can be stored and transported e.g. in a dispenser housing 450, but this is not limiting to the invention. Figure 19 and figure 20 show different possible embodiments of dispenser housings 450, e.g. as a box or as a drum. Alternatively, the flexible punched tape 40 can also be rolled up or folded together without housings being provided specifically for this purpose or, even further alternatively, can be provided in the stack of uniformly cut strips.

[0169] Figure 21 shows a connector 50 which is suitable for use in a fastening set according to one embodiment of the invention. Such connectors 50 can be used to connect a plurality of punched tapes 40 to one another, for instance at crossing points or for the lengthening thereof. The connector 50 is purely by way of example but is designed in a non-limiting manner as a stud 52. The stud 52 comprises a head region 522, a body region 524 and a cone region 526. The stud 52 has rotational symmetry, wherein the head region 522 has a larger diameter than the body region 524 and the cone region 526. Naturally, other embodiments are conceivable.

[0170] The connector 50 is dimensioned in order to connect two punched tapes 40 to one another. For this purpose, the through-openings 442 of a first punched tape 40 and a further punched tape 40 are placed one on top of the other and the connector 50 is pressed with its cone region 526 through the through-openings 442 which lie one on top of the other until both punched tapes 40 are clamped between the head region 522 and the cone region 526.

[0171] In order to release the connection of the components, the connector 50 is destroyed, for example by means of pincers. In this manner, two punched tapes 40 can be separated from one another and recycled.

[0172] The stud 52 can also be designed in two parts and e.g. fitted together using riveting tongs or a rivet gun, thus connecting the components to be connected, e.g. punched tapes 40 and mounting plates 30.

[0173] Figure 22 shows a perspective view of a purely schematically illustrated anchoring bracket 20 according to one possible embodiment of the invention. The anchoring bracket 20 comprises a foot region 22 and a supporting region 24 extending perpendicularly therefrom. The supporting region 24 has a first portion L approximately in the thickness of the insulation layer and then a portion with a toothed profile 242 for receiving the mounting plate 30. This is followed by a further portion S in the thickness of the rear ventilation gap and a portion for fixing the fagade cladding.

[0174] The foot region 22 comprises two openings as first attachment points 222 to receive screws for the purpose of dowel-connecting to a wall portion. In a purely schematic manner, two attachment points 28 for profile elements (not illustrated) are shown, to which a facade cladding can be fastened, in the form of openings in the supporting region 24 of the anchoring bracket 20. The anchoring brackets 20 and the profile elements (not illustrated) form, together with their fastening means, the sub-structure of a curtain-wall fagade. In the illustrated embodiment, a toothed profile 242 with a plurality of merlons 244 and notches 246 is located on the upper edge of the supporting region 24. A merlon 244 and a notch 246 can each be formed the same size, for example in each case between 2 mm and 15 mm, preferably between 3 mm and 10 mm. Alternatively the notches 246 and the merlons 244 can also be of different sizes. The width of the notch 246 is preferably matched to the thickness of the mounting plate 30 and so the mounting plate 30 is firmly seated in terms of a form-fitting connection of the mounting plate 30 on the supporting region 24. The anchoring bracket 20 in figure 22 is compatible with the previously described embodiments of the mounting plate 30.

[0175] Figure 23 shows an anchoring bracket 20 according to an alternative embodiment of the invention. The anchoring bracket 20 is designed substantially like the anchoring bracket 20 described previously with reference to figure 22, and comprises the foot region 22 and the supporting region 24 with the portions L and S, as well as the toothed profile 242, wherein, in this case by way of example, alternatively a single long hole is provided as a first attachment point 222 for fastening the anchoring bracket 20 to the wall portion and a single further long hole is provided as a second attachment point 28 for fastening the profile elements for the fagade cladding.

[0176] The anchoring bracket 20 illustrated in figure 23 differs from the embodiment illustrated in figure 22 substantially in the configuration of the toothed profile 242. The toothed profile 242 (illustrated in greater detail in figure 24) comprises a number of hooks 241 which are each provided with a lug 243 facing the foot region 22. Located below the lug 243 is an undercut 245 in the notch 246. The toothed profile 242 with the undercut 245 can be produced in a simple manner by a punching process. The advantages of the embodiment of figure 23 and figure 24 reside in the combination with the mounting plate 30 which has been described in connection with figure 7. Reference can be made at this juncture to the statements made in this respect.

[0177] Figure 25 shows a wall portion 10 with anchoring brackets 20 fastened therein and two insulation elements 14 in a state which is shown in one implementation of the method in accordance with the invention. The anchoring brackets 20 are illustrated in this case, purely by way of example but not limiting to the invention, as L-shaped profiles and each have a foot region 22 and a supporting region 24. The foot region 22 is connected, for example dowelled, to the wall portion 10. The supporting region 24 protrudes perpendicularly from the wall portion 10 and forms the sub-structure for the curtain-wall fagade (not illustrated). In this case, two second attachment points 28 in the form of openings in the supporting region 24 of the anchoring bracket 20 are illustrated purely schematically.

[0178] When carrying out the method in accordance with the invention, the anchoring brackets 20 are first fastened to the wall portion 10 of a construction, wherein this is preferably effected in a regular pattern as illustrated, in which the distances between the anchoring brackets 20 are in each case equidistant preferably both horizontally as well as vertically and are selected according to the necessary structural calculation.

[0179] The insulation elements 14, for example mineral wool insulation slabs, are attached to the wall portion 10 in that they are slit and placed onto the anchoring brackets 20. In addition or alternatively, anchoring brackets can be attached to the wall portion 10 in the joints between insulation elements 14. Thereafter, the supporting regions 24 of the anchoring brackets 20 protrude with their second attachment points 28 out of the insulation elements 14.

[0180] Figure 26 shows a further state after the method in accordance with the invention has been carried out, specifically at a time after the state illustrated in figure 25. For a better overview, the individual insulation elements 14 are in this case no longer shown, otherwise the view corresponds to figure 25. The insulation elements 14 jointly form an insulation layer 12 which lies directly against the wall portion 10. Mounting plates 30 were in each case initially fitted on the anchoring brackets 20, and moreover with the aid of their receiving slot 322 or 326, as described with reference to figure 3 to figure 8, and optionally then protected against slipping, as described with reference to figure 8 or figure 13 to figure 18. In each case, two mounting plates 30 are connected to each other by means of one or more punched tapes 40.

[0181] A preferred system is achieved when using punched tapes 40 in the form of figure 19 and figure 20. The length of the punched tape 40 can be adapted directly on the building site. The punched tape 40 is cut to size according to the distance between two anchoring brackets 20 or is otherwise cut open at its perforation 446, if provided. The punched tape 40 is connected to the mounting plates 30, generally under tension, i.e. in a stretched state, by means of the fastening elements 342. Provision can also be made to connect a plurality of punched tapes 40 by means of connectors 50 to form a longer punched tape 40.

[0182] It is possible to connect the anchoring brackets 20 diagonally in each case, as illustrated. Alternatively or in addition, it is possible e.g. to connect two anchoring brackets 20 disposed horizontally next to each other in each case and / or anchoring brackets 20 disposed vertically with respect to each other in each case.

[0183] Figure 27 shows an alternative image to figure 26, which can result after attaching the punched tapes 40 and mounting 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. In this embodiment, the anchoring brackets 20 are disposed in a substantially regular grid pattern distributed horizontally and vertically over the wall portion 10. The grid pattern of the anchoring brackets 20 is generally determined by the structural requirements of the covering. In each case, two anchoring brackets 20 are connected to each other diagonally, wherein the punched tapes 40 cross each other and form a net-like structure. This makes possible additional securing of the fastening arrangement.

[0184] Figure 28 shows the state of the system of figure 27 according to a further optional method step. Two punched tapes 40 are each joined together at the crossing points by means of connectors 50. This makes possible additional securing of the fastening arrangement.

[0185] Figure 29 shows an alternative image to figure 27, which can result after attaching the punched tapes 40 and mounting 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. In this embodiment, purely by way of example only in the lowermost row are the mounting plates 30 fitted on the anchoring brackets 20 in the opposite direction to the mounting plates 30 opposite them, i.e. in this case from below and not from above. When subjected to tensile stress by the punched tapes 40, the anchoring bracket 20 prevents the mounting plate 30 from lifting off.

[0186] It is apparent that the arrangement of opposite mounting plates 30 in mirror- symmetrical form illustrated in figure 29 also offers advantages in connection with the arrangement of the punched tapes 40 illustrated in figure 26.

[0187] Figure 30 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. Naturally, 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.

[0188] The anchoring brackets 20 of the two wall portions 10 forming the corner region 18 are perpendicular to each other. Both anchoring brackets 20 with three second attachment points 28, which are shown in this case purely by way of example and schematically and of which one is a long hole, are provided with mounting plates 30. A flexible punched tape 40, which extends from the first mounting plate 30 to the second mounting plate 30, bridges the corner region 18. On the end side, the punched tape 40 is fastened in each case to the fastening elements 342 of the two mounting plates 30. Although, in the illustrated embodiment, the punched tape 40 is bent over the corner region, provision can alternatively be made that the punched tape 30 is also bent at the corner region 18 (not illustrated).
