Description

[0001]

[0002] The invention relates to a mounting plate, 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 fagade cladding.

[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. 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 are held in place by dowels not at specific points but rather in a planar 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 crossties 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.

[0014] OBJECT OF THE INVENTION

[0015] The object of the invention is to provide a mounting plate, and 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.

[0016] A further object of the invention is to provide a method for producing a rear-ventilated fagade which overcomes the disadvantages described above.

[0017] DISCLOSURE OF THE INVENTION

[0018] The object is achieved by a mounting plate, 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 linear tensioning element. 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 portion with at least one fastening element which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto or can be made into such a configuration by bending or folding, and that the tensioning element can be fastened 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 linear tensioning elements, for instance cables, cords or wires, is that the insulation elements are not held at specific points by dowels but rather are pressed in a linear manner against the wall portion. The linear tensioning elements 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 cables, chords or wires 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 linear tensioning elements, it is possible to secure the corner region, as described in more detail below, in particular also with reference to the figures. The bridging of the corner regions of the construction and the joints between the insulation elements by means of the linear tensioning elements 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. 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, especially since the proposed solution is also UV- resistant.

[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. Hospitals, old people's homes, schools, hotels and the like can be refurbished in terms of energy during ongoing operations.

[0027] Mounting plate-base body

[0028] According to one embodiment, the two-dimensional base body of the mounting plate is substantially rectangular. Preferably, however, other shapes are also possible, in particular 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.

[0029] The mounting plate base body can be manufactured from metal or as an injection- moulded synthetic material part, in particular PP, PE, PLA. The base body can have coloured layers or protective layers or the like, in particular can be e.g. black anodised.

[0030] 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. 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 or a receiving opening 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 formfitting 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 fit-on portion of the clamping plate is designed for forming a form-fitting connection and / or frictional connection to an anchoring bracket.

[0033] In a preferred manner, provision is made that the fit-on portion of the mounting plate comprises at least one receiving slot or a receiving opening 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.

[0034] 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.

[0035] According to one embodiment, the mounting plate comprises a first receiving slot which extends from an edge of the mounting plate inwards into the two-dimensional base body. The shape of the receiving slot is in principle arbitrary, for instance the first receiving slot can be formed e.g. so as to taper from the edge of the mounting plate in the direction of a centre of the mounting plate or from the centre of the mounting plate in the direction of the edge of the mounting plate. The shape of the receiving slot, which is formed so as to taper from the centre of the mounting plate in the direction of the 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.

[0036] Alternatively, the receiving slot can be designed with a constant width.

[0037] In addition or alternatively, the mounting plate comprises a second receiving slot which is arranged in the two-dimensional base body, i.e. without an edge aperture and spaced apart from its edge. The second receiving slot is preferably arranged approximately in the centre. The second receiving slot can have any shape, in particular straight, wedge- shaped or tapering towards one side, in particular preferably adapted to the shape of an anchoring bracket system.

[0038] In addition or alternatively, the mounting plate comprises a receiving opening which is preferably arranged in the two-dimensional base body, i.e. without an edge aperture and spaced apart from its edge. The receiving opening is preferably arranged approximately in the centre. The receiving opening is round or has a roundish, polygonal cross-section, in particular preferably adapted to the shape of an anchoring bracket system.

[0039] In a preferred manner, provision is made that the mounting plate comprises a plurality of receiving slots or receiving openings which enable compatibility with anchoring brackets from different manufacturers. For example, and preferably, the mounting plate comprises at least the above-described first receiving slot, second receiving slot and the receiving opening. By providing differently dimensioned slots and openings, in particular in relation to the slot length and diameter of the opening, the mounting plate is adaptive and can therefore be used internationally and independently of the manufacturer, i.e. universally. Preferably, a receiving slot is also designed in such a way that, in addition, a basement ceiling insulation can also be installed with a subsequent suspended ceiling, in particular by means of so-called Nonius hangers. Mounting plate-fastening elements

[0040] Furthermore, the mounting plate has at least one fastening portion, preferably with a 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 or can be made into such a configuration by deformation, for instance bending or folding.

[0041] In one embodiment, the fastening portion comprises at least one through-opening. The through-opening is dimensioned such that the tensioning element can be guided therethrough.

[0042] However, in a preferred manner provision is made that the mounting plate has a fastening portion with at least one fastening element. The fastening element is designed in such a way that the tensioning element can be tensioned around it. The fastening element can be arranged in the plane of the base body, e.g. as a hook, or as a ring of teeth, merlons or rods having inwardly or outwardly oriented teeth, merlons or rods. Alternatively, the fastening element can be provided extending at least in sections from the two-dimensional base body in a direction perpendicular thereto. Provision can be made that the fastening element can be moved to a position by deformation, e.g. by bending or folding, so that it extends, starting from two-dimensional base body, at least in sections in a direction perpendicular thereto.

[0043] 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.

[0044] 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. 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 head portion is e.g. 20% to 100% larger than the diameter of the stem portion.

[0045] According to a preferred embodiment, the fastening element has a hook-like design and comprises a portion which extends preferably in a direction away from the edge of the mounting plate or in a direction towards the edge of the mounting plate, e.g. a flat piece.

[0046] According to one embodiment, provision is made that the fastening portion comprises a plurality of fastening elements. In a preferred manner, provision is made that the fastening portion comprises three or more, more preferably six or more, still more preferably ten or more, particularly preferably fifteen or more fastening elements. Furthermore, it is preferred that the plurality of fastening elements is arranged in a ring shape along the edge of the mounting plate. By reason of the large number of fastening elements, particularly if they are arranged in a circle around the edge of the two- dimensional base body, the mounting plate can be spanned in a variety of ways by linear tensioning elements, e.g. also multiple times and at different points, so that different types of nets can be produced.

[0047] In particular, it is preferred that the fastening elements form a ring of hooks. The hooks can advantageously be oriented alternately in relation to a direction away from the edge of the mounting plate or towards the edge of the mounting plate, which increases the various spanning options still further.

[0048] In a preferred manner, provision is made to manufacture the mounting plate as a punched piece from a metal strip, wherein at least one hook-like fastening element, preferably each 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 deformed, e.g. bent 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.

[0049] Further alternatively, the fastening element can also be designed e.g. as a pin, having a cylindrical stem portion without a specially configured head.

[0050] In the embodiments described, the fastening element, in particular its stem section if present, preferably has a height such that at least two tensioning elements can be tensioned around it or can be fixed on it.

[0051] Preferably, the mounting plates can be manufactured in one piece from metal or as injection-moulded synthetic material parts, in particular PP, PE, PLA.

[0052] Tensioning elements

[0053] Within the scope of the present invention, linear tensioning elements are understood to be elongate components which guarantee tensile strength and can include both rigid embodiments and, what is preferable, flexible embodiments. In particular, the linear tensioning element can be designed as a cable, cord or wire.

[0054] The linear tensioning element is or comprises preferably an extruded part. It can be a single strand of material or comprise a plurality of individual strands of material which are connected to one another, e.g. twisted together, beaten, braided, in the form of a cord or connected in a similar way.

[0055] In one embodiment, the tensioning element is a metal cable or metal wire. The metal cable and the metal wire consist in particular of a flexible metal, in particular stainless steel, which is preferred, or of aluminium or an aluminium alloy. The wire can also consist of a synthetic material-encased or rubber-encased metal.

[0056] In an alternative embodiment, the tensioning element is a synthetic material cord or a synthetic material cable, in particular made of synthetic materials, such as PA, PE, PES, PET, PP or a composite material. In a still alternative embodiment, the tensioning element is a cord or a cable made of natural or synthetic fibres, e.g. cotton, jute, flax, hemp, coconut, carbon fibre, glass fibre or a composite material or the like.

[0057] In particular, it is preferred that the linear tensioning element has a tensile strength > 50 MPa, preferably > 100 MPa, more preferably > 200 MPa, even more preferably > 500 MPa, and particularly preferably > 1000 MPa, wherein the tensile strength is determined in accordance with ISO 6892-1 :2019 in the case of a metallic tensioning element (40) and is determined in accordance with ISO 527-1 :2019 in the case of a tensioning element (40) made of synthetic material. In the case of such tensile strengths, excessive yielding against bulging of the insulation elements and also tearing can be effectively prevented. A tensile strength > 500 MPa, in particular > 1000 MPa, also enables suspended installation of insulation elements.

[0058] The tensioning element is preferably round in cross-section and preferably has a diameter of 0.1 mm to 5 mm, more preferably of 0.5 mm to 2 mm, particularly preferably of approximately 1 mm.

[0059] The tensioning element can be provided on a winding core or in a dispenser and can be cut to length as required on site.

[0060] Anti-slip device

[0061] 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.

[0062] The anti-slip device can be formed by bent portions, in particular preferably by means of spring disks in the region of the fit-on portion of the mounting plate, in particular as a lateral delimitation of the receiving slot or of the receiving opening. 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. The bent portions, e.g. spring disks, 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.

[0063] The bent portions, e.g. spring disks, 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.

[0064] 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 generating sufficient static friction, e.g. by connecting, e.g. bracing the mounting plate and the anchoring bracket against one another or by means of 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.

[0065] The anti-slip device can be provided in the form of further individual parts in the set, which are referred to below as anti-slip parts.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Spanning

[0071] The mounting plate preferably has means which allow it to be used even without being placed or clamped onto an anchoring bracket for the purpose of fastening the insulation layer. Regions of the insulation layer which are equipped with no or too few anchoring brackets can be bridged by spanning individual mounting plates by means of the linear tensioning elements.

[0072] According to one embodiment, provision is made that the mounting plate comprises a bridging device which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto or can be made into such a configuration by deformation, for instance bending or folding. The bridging device can comprise e.g. one or more spokes which extend from a middle of the two-dimensional base body in the direction of the edge or vice versa. An advantageous embodiment is formed by means of a bridging device comprising two spokes, wherein the spokes are opposite each other and extend in opposite directions.

[0073] The bridging device comprises one or more receivers for the linear tensioning element, so that the bridging device is suitable for building up a force component perpendicular to the plane of the two-dimensional base body when spanning with a linear tensioning element.

[0074] In particular, it is preferred if the receivers for the linear tensioning element are designed in the form of guide grooves on the spokes, in particular e.g. in the form of notches at the head end of the spokes.

[0075] Furthermore, it is preferred that the mounting plate comprises at least one anchoring spoke which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto or can be made into such a configuration by deformation, for instance bending or folding. The anchoring spoke preferably comprises one or more latching strips on the edge, in particular with barbs. This makes it possible to press the anchoring spoke into the insulation material in such a way that the mounting plate is provisionally held in a fixed position. The mounting plate can therefore also be fastened to the wall portion without an anchoring bracket. After spanning by means of the linear tensioning element, the normal force component and the anchoring spokes ensure that the mounting plate is in a fixed position. In the final installation state, depending on the width of the air gap, the mounting plate may be additionally secured in position by virtue of the bridging device lying on the rear side against the fagade cladding.

[0076] Anchoring brackets

[0077] 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. According to one embodiment, the anchoring bracket is designed as an L-profile having a foot region, which can be fastened to the wall region, and a sword-shaped supporting region which extends perpendicularly thereto. The anchoring bracket having an L-profile can be designed in an advantageous manner simply from a punched profile.

[0078] Alternatively, the anchoring bracket is designed as a rod-shaped fagade anchor with a foot region which can be fastened to the wall region and a preferably collinearly adjoining rod-shaped supporting region. Such a rod-shaped fagade anchor, e.g. having a metal core for introducing the loads of the fagade cladding into the wall portion and having a glass fibre sheath for thermal insulation, is particularly advantageous, e.g. in relation to minimising heat bridges.

[0079] Even further alternatively, the anchoring bracket is designed as a hanger with a foot region which can be fastened to a wall region, in particular a ceiling region, and an adjoining supporting region, wherein the supporting region comprises at least one II- profile, preferably two U-profiles which can be displaceably received one inside the other in order to adjust a longitudinal dimension of the anchoring bracket. This additionally allows the installation of basement ceiling insulation with a subsequently suspended ceiling.

[0080] In a particularly preferred manner, the mounting plate is designed as a clamping plate, wherein the first receiving slot, the second receiving slot and / or the receiving opening are matched to the width of the anchoring bracket in such a way that a form-fitting connection and / or frictional connection can be formed when the mounting plate is fitted on the anchoring bracket.

[0081] For example, the anchoring bracket can have a grooved profile, which additionally supports the clamping effect of the mounting plate, particularly in the case of a sword- shaped supporting region. This also allows the use of the mounting plate in combination with harder bracket materials, such as stainless steel, in which the clamping effect is provided by the form-fitting clamping in the grooves.

[0082] Alternatively, provision is made that the first receiving slot, the second receiving slot and / or the receiving opening are matched to the width of the anchoring bracket in such a way that the mounting plate can be placed loosely on the anchoring bracket.

[0083] 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 formfitting 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] Method

[0088] The invention also includes a use of one of the described fastening sets to produce or to construct a rear-ventilated fagade.

[0089] 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) attaching at least one linear tensioning element to at least one fastening element of a first mounting plate, g) tensioning the linear tensioning element over one or more insulation elements in order to hold the insulation layer against the wall portion, preferably with the formation of a net by connecting, in particular hooking, the tensioning element to or on further fastening elements of one or more further mounting plates and h) attaching the tensioning element to at least one fastening element of a second mounting plate, i) optionally intermediate positioning and spanning one or more still further mounting plates, j) optionally repeating steps f) to i) or steps a) or b) to i), and k) attaching a fagade cladding to the supporting regions of the anchoring brackets by means of connection profiles. In the case of the method in accordance with the invention, it is ideally possible to completely dispense with dowels and the attachment thereof to the anchoring base. Only anchoring brackets are fastened to the wall portion, wherein the anchoring brackets have the function of supporting the fagade cladding. The proposed solution therefore has the advantage that no dust or noise is generated during the attachment of the fastening set. Therefore, in an advantageous manner no tool, such as a drill or hammer, is required and no electrical tool is required at all. Installation is considerably (up to ca. 90%) faster compared with drilling and hammering-in dowels.

[0090] Installation is possible irrespective of the material of the wall portion of the building. The substrate, including e.g. Ytong, vertically perforated bricks or the like, is subjected to minimal stress. In addition, the method is independent of any insulation material thickness because the mounting plate is clamped visually and as a termination element.

[0091] When using metallic elements, the fastening set is non-flammable.

[0092] The fastening set can be removed without leaving any residue and is recyclable.

[0093] In an advantageous manner, the system is installed particularly quickly. By reason of the insulation being attached in sections, i.e. the insulation elements are installed in a step-by-step procedure, the method allows work to be carried out visually. No prior knowledge is required for the installation because the system is self-explanatory and can also be corrected if necessary.

[0094] 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 linear tensioning element, and optionally anchoring brackets 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.

[0095] Therefore, the mounting plates preferably each have a two-dimensional base body with a fit-on portion for fitting onto an anchoring bracket and a fastening portion, preferably with at least one, preferably a plurality of fastening elements which extend from the two-dimensional base body at least in sections in a direction perpendicular thereto or can be made into such a configuration by deformation, for instance bending or folding.

[0096] 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 form-fitting 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.

[0097] 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 tensioning elements. After attachment, the tensioning elements preferably lie directly on the insulation layer.

[0098] 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 tensioning element 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.

[0099] 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 or of the receiving opening, in particular for instance by means of spring disks, the anti-slip device can already be provided when said mounting plate is fitted on in step c).

[0100] In step d) of providing anti-slip protection, provision can be made to introduce an antislip element, such as e.g. a sealing or adhesive tape, a cap or a buckle, 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, 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.

[0101] In order to provide anti-slip protection, the tensioning element can also be tensioned over two or more fastening elements of the mounting plate, with the anchoring bracket being braced with the mounting plate.

[0102] 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.

[0103] 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 tensioning element 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 so that the first receiving slots point in the opposite direction, and to brace them against one another by means of tensioning elements.

[0104] The use of the tensioning element additionally as an anti-lift device or anti-slip device has the advantage that the set has very few individual parts.

[0105] In step g) of tensioning the linear tensioning element over one or more insulation elements in order to hold the insulation layer against the wall portion, a tensioning element net is formed by connecting, in particular hooking, the tensioning element to or on further fastening elements of one or more further mounting plates. In particular, the net can comprise uniform patterns, for instance zigzag patterns, horizontal or vertical lines or the like, or it can also extend in a chaotic manner. Depending on the required structural calculation, a variable configuration of the net is possible, even with double-tensioned and / or crossing lines.

[0106] In step i) of the optional intermediate positioning and spanning of one or more additional mounting plates, provision can be made to initially bend an anchoring spoke in a direction perpendicular to the two-dimensional base body, preferably by 90°, and use same in order to fasten the mounting plate in the insulation element. A location is selected where the net extends and where the distance between the mounting plates is to be bridged. At this location, the further mounting plate is placed approximately in the centre under the tensioning element, e.g. wire, and the anchoring spoke is pressed into the insulation element, preferably with barbs. The bridging device is moved to a functional position, e.g. by bending two opposing spokes in the opposite direction to the anchoring spoke. Finally, the already tensioned tensioning element is hooked into the receivers of the spokes (e.g. notches). By bending the two spokes upwards, the insulation material is better secured in position over the tensioned wire netting.

[0107] Preferably, spanning is carried out if the grid pattern of the anchoring brackets exceeds a defined value, e.g. more than 750 mm x 750 mm, or e.g. if individual insulation elements are not fitted onto anchoring brackets on the wall portion.

[0108] Within the scope of the method in accordance with the invention, provision can advantageously be made for using the tensioning elements 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 tensioning elements. By virtue of the mounting plates for holding the insulation elements, no tensioning elements 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 tensioning elements 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 tensioning elements, 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 tensioning elements can be varied in order to ensure that the insulation elements are secured. Provision can likewise be made to add individual mounting plates in regions of the fagade subject to particular stress, e.g. in edge and corner regions where higher wind loads occur, and to span them in the manner described.

[0109] 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.

[0110] Advantageously and preferably, the tensioning elements can be provided on a winding core and cut to length on site during installation. This means that in each case a tensioning element can be used in order to connect the mounting plates to one another. Alternatively, e.g. in the case of tensioning elements having a prefabricated length dimension, provision can be made that a plurality of tensioning elements are used in order to bridge distances between mounting plates which are to be connected. The tensioning elements can be connected to one another 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.

[0111] With the method in accordance with the invention, a corner region of the wall portion of the construction can also be bridged and secured by means of tensioning elements.

[0112] 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.

[0113] In accordance with the invention, a mounting plate for fastening an insulation layer to a wall portion of a construction, in particular for forming a rear-ventilated fagade, said wall portion being provided with a number of anchoring brackets, has a two-dimensional base body. The two-dimensional base body comprises a fit-on portion for fitting on an anchoring bracket. The fit-on portion comprises: at least one first receiving slot which extends from an edge of the mounting plate inwards into the two-dimensional base body and / or at least one second receiving slot which is arranged in an area of the two- dimensional base body spaced apart from the edge, and / or

[0114] - at least one receiving opening which is arranged in the area of the two- dimensional base body.

[0115] 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 thereto, or can be made into such a configuration by deformation, for instance bending or folding.

[0116] In accordance with the invention, the mounting plate may be provided with one or more of the features as described above in the context of the fastening set. It should be understood that the advantages of the features explained above are disclosed in the context of the claimed mounting plate itself, too. Specifically, the mounting plate may be part of the fastening set which may additionally comprise one or more preferably linear tensioning elements, optionally anchoring brackets and anti-slip devices.

[0117] Specifically, the fastening element of the mounting plate may have a hook-like design and comprise a portion which extends preferably in a direction away from the edge of the mounting plate or in the direction towards the edge of the mounting plate.

[0118] The mounting plate may comprise a plurality of fastening elements, preferably three or more, more preferably six or more, still more preferably ten or more, particularly preferably fifteen or more fastening elements.

[0119] The mounting plate may comprise a plurality of fastening elements which are arranged in a ring shape along the edge of the mounting plate.

[0120] The fastening elements may form a ring of hooks, wherein the hooks are oriented alternately in relation to a direction away from the edge of the mounting plate or towards the edge of the mounting plate.

[0121] The mounting plate may comprise an anti-slip device, which is designed to secure the mounting plate to prevent it from slipping on the anchoring bracket, wherein the anti- slip device is preferably formed by means of spring disks in the region of the fit-on portion, particularly preferably by means of bent spring disks.

[0122] The mounting plate may comprise a bridging device which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto or can be made into such a configuration by deformation, for instance by bending or folding. The bridging device may comprise one or more receivers for a preferably linear tensioning element, so that the bridging device is suitable for building up a force component perpendicular to the plane of the two-dimensional base body when spanning by means of the preferably linear tensioning element.

[0123] The bridging device may comprise at least two spokes which are preferably opposite each other and extend from the middle of the two-dimensional base body in the direction of the edge or vice versa, wherein the receivers for the preferably linear tensioning element are designed preferably in the form of notches on the head end of the spokes.

[0124] The mounting plate may comprise at least one anchoring spoke which extends, starting from the two-dimensional base body, at least in sections in a direction perpendicular thereto or can be made into such a configuration by deformation, for instance by bending or folding.

[0125] The at least one anchoring spoke may comprise at least one latching strip, preferably in the form of barbs.

[0126] The two-dimensional base body may comprise a slip-in window.

[0127] The invention also relates to a use of the described mounting plate as to produce a rear-ventilated fagade.

[0161] EMBODIMENTS OF THE INVENTION

[0162] 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.

[0163] 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. Figure 3 shows a mounting plate 30 which is suitable for use in a fastening set according to one embodiment of the invention.

[0164] The mounting plate 30 comprises a two-dimensional base body 34 which is circular in shape and has e.g. a diameter of 25 cm and a plate thickness of 0.6 mm.

[0165] In this embodiment, an fit-on portion 32 of the two-dimensional base body 34 comprises a first receiving slot 326 which extends, starting from an edge of the two-dimensional base body 34, in a straight line to its middle 38.

[0166] In this embodiment, the fit-on portion 32 of the two-dimensional base body 34 also comprises a second receiving slot 334, which extends centrally, but slightly offset with respect to the middle 38, in the two-dimensional base body 34.

[0167] Finally, in this embodiment, the fit-on portion 32 of the two-dimensional base body 34 comprises a receiving opening 332, which is arranged centrally, but slightly offset with respect to the middle 38, in the two-dimensional base body 34.

[0168] The first receiving slot 326, the second receiving slot 334 and the receiving opening 332 are each delimited on the edge side by spring disks 330, which form an anti-slip device when the mounting plate 30 is placed on the anchoring bracket 20. In the case of the first and second receiving slots 326, 334, the spring disks 330 form two disk strips along the slot. At the receiving opening 332, the spring disks 330 form a starshaped ring of disks. 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 spring disks 330 means that elastic spring-back is resisted by the insulation material.

[0169] The illustrated mounting plate 30 is advantageously adaptive in relation to the use with anchoring brackets 20 from different manufacturers (cf. figures 21 - 26). The first receiving slot 326 is compatible with the sword-shaped supporting region 24 of the L- shaped anchoring bracket 20 in figures 21 - 24. The second receiving slot 334 is compatible with the U-shaped supporting region 24 of the anchoring bracket 20 in figure 26. The receiving opening 332 is compatible with the rod-shaped supporting region 24 of the rod-shaped anchoring bracket 20 in figure 25.

[0170] In further embodiments which are not illustrated, the fit-on portion 32 can also comprise more elements, i.e. further receiving slots or further e.g. circular receiving openings. In other embodiments which are not illustrated, the fit-on portion 32 can also comprise fewer elements, e.g. no or fewer receiving slots or, still further alternatively, no circular receiving openings.

[0171] In further embodiments which are not illustrated, the elements of the fit-on portion 32 can also be arranged differently. For example, the second receiving slot 334 arranged in the two-dimensional base body 34 can be arranged in the middle 38 and the first receiving slot 326 can extend only over a part of the radius length of the mounting plate 30. Alternatively, provision can likewise be made that the receiving opening 332 is located in the middle 38 of the mounting plate 30 and the receiving slots 326, 334 are arranged eccentrically or end outside the middle 38.

[0172] The illustrated embodiment of the mounting plate 30 is in particular compatible with the embodiment of the anchoring bracket 20 in figure 22, 23 or 24. The mounting plate 30 additionally comprises, above the first receiving slot 326, 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 engages into the slip-in window 325. By reason of the elastic spring-back of the insulation material, the mounting plate 30 is urged 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.

[0173] The mounting plate 30 further comprises, purely by way of example, 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. The material notches 344 can be dimensioned such that a tensioning element 40 (not illustrated), in particular a cable, cord or wire depending on the embodiment, can be guided therethrough. Thus, the material notches 344 form a part of the fastening portion of the mounting plate 30, which is provided for the purpose of interacting with the tensioning element 40 (not illustrated).

[0174] The annular outer edge 348 with the fastening elements 342 provided thereon forms a further part of the fastening portion of the mounting plate.

[0175] A plurality of fastening elements 342, in this case fifteen hook-like or tab-like fastening elements, which can be designed as illustrated in figure 12 or 13, are located circumferentially for attaching the tensioning element 40 to the two-dimensional base body 34. In particular, the fastening elements 342 can be produced from partial cutouts 64 of the two-dimensional base body 34 (cf. figure 12 or 13 and description thereof).

[0176] The fastening elements 342 together form a ring 350 of hooks. The hooks of the ring 350 of hooks can be oriented alternately in relation to a direction away from the edge of the mounting plate 30 or towards the edge as illustrated or in each case can be oriented in the same directions (not illustrated), i.e. with the end towards the middle 38 of the mounting plate 30 or in the direction of its edge. A radial arrangement of the fastening elements 342 around the central opening 324 is advantageous insofar as it permits attachment options for tensioning elements 40 in different directions away from the central opening 324.

[0177] The mounting plate 30 comprises a bridging device 364 which is formed from two spokes. The two spokes are opposite one another in relation to the middle 38 of the mounting plate 30. They extend from the middle 38 towards the edge, but are unconnected or at least connected in an easily detachable manner to the annular outer edge 348. At the end of the spokes, these are each provided with two notches which form receivers 366 for the linear tensioning element 40.

[0178] Starting from the flat position illustrated, the spokes can be bent in at least one direction, i.e. out of the plane of the drawing or into the plane of the drawing. In other words, the spokes of the bridging device 364 can be made into a configuration such that they extend, starting from the two-dimensional base body 34, at least in sections in a direction perpendicular thereto (in this case out of the plane of the drawing or into the plane of the drawing). When spanning with a linear tensioning element 40, a force component can be built up perpendicular to the plane of the two-dimensional base body 34 which holds the mounting plate 30 on the wall portion in a position, in which it can support the insulation elements of an insulation layer 12. Cf. figures 32 and 33 and description.

[0179] The mounting plate 30 also has an anchoring spoke 360 which extends from the middle 38 of the two-dimensional base body 34 in the direction of its edge. The anchoring spoke 360 is unconnected or at least connected in an easily detachable manner to the annular outer edge 348. In an embodiment which is not illustrated, the anchoring spoke 360 can extend from the edge to the middle 38 of the two-dimensional base body 34.

[0180] The anchoring spoke 360 can be made into a configuration such that it extends, starting from the two-dimensional base body 34, at least in sections in a direction perpendicular thereto (in this case out of the plane of the drawing or into the plane of the drawing).

[0181] The anchoring spoke 360 is provided on the edge side with two latching strips 362 in the form of barbs. After insertion into an insulation element, the anchoring spoke 360 holds the mounting plate 30 in a fixed position on the wall portion.

[0182] Figure 4 shows a mounting plate 30 according to a further embodiment of the invention. As in figure 3, the mounting plate 30 comprises the circular two-dimensional base body 34 which has e.g. a diameter of 25 cm and a plate thickness of 0.6 mm.

[0183] However, the fit-on portion 32 of the mounting plate 30 comprises in this case only the first receiving slot 322 which extends from the edge of the mounting plate 30 inwards into the two-dimensional base body 34.

[0184] As in the embodiment illustrated in figure 3, the central opening 324 is formed in the middle 38 of the mounting plate 30, but in this embodiment the slip-in window 325 has been omitted, which is not limiting to the invention. In the illustrated embodiment, seven fastening elements 342 are provided circumferentially, which is not limiting to the invention.

[0185] In the perspective view, it can be seen that the seven fastening elements 342 extend in sections in a direction perpendicular to the two-dimensional base body 34 of the mounting plate 30, namely into the plane of the drawing. The spring disks 330 also extend in a direction perpendicular to the two-dimensional base body 34, preferably in the same direction as the fastening elements 342, but this is not limiting to the invention.

[0186] Figure 5 shows a mounting plate 30 according to an alternative embodiment having 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.

[0187] 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 the middle 38 of the mounting plate 30 towards the edge of the mounting plate 30. The tapered 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 21) and fixedly clamped.

[0188] 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.

[0189] 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 (as described in figure 3 or 4) or even other geometries are covered by the invention, e.g. with a circular or polygonal contour.

[0190] A central opening 324 is formed in the middle 38 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 tensioning elements 40 in different directions away from the central opening 324.

[0191] Figure 6 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.

[0192] In contrast to the embodiment described with reference to figure 5, the mounting plate 30 comprises a fit-on portion 32 which is formed as a straight first 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 first 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.

[0193] Above the central opening 324, which is advantageous in this case but not necessarily provided, is a placement notch 328 which is matched to the toothed profile 242 of the anchoring bracket 20 illustrated in figures 21 - 24. 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 previously described embodiments in figures 3 - 5 can likewise be provided with placement notches 328. The further statements relating to the embodiment described in figure 5 also apply to the embodiment illustrated in figure 6, wherein no repeated description will be given.

[0194] Figure 7 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 7 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 12 or 13.

[0195] Figure 8 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. The previously described embodiments in figures 3 - 5 can comprise fastening elements 342 configured in the same manner.

[0196] Figure 9 shows a perspective view of a mounting plate 30 according to a further embodiment of the invention. As in figure 8, 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. The material notches 344 can be dimensioned such that a tensioning element 40 (not illustrated), e.g. a cable, cord or wire depending on the embodiment, can be guided therethrough.

[0197] The design of the mounting plate 30 is compatible in particular with the embodiment of the anchoring bracket in figures 22 - 24. In contrast to the mounting plate 30 described with reference to figure 8, this additionally comprises, above the central opening 324, the slip-in window 325 which is already described in relation to figure 3 and which is matched to the size of the 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.

[0198] Figure 10 shows a side sectional view of a part of a mounting plate 30 according to one embodiment of the invention.

[0199] A portion of the two-dimensional base body 34 is illustrated, to which a fastening element 342 for fastening a tensioning element 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.

[0200] 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.

[0201] The stem portion 62 has a height h and a diameter d. The height h is adapted in order to receive a plurality of tensioning elements 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.

[0202] A tensioning element 40 can be fastened to the fastening element 342, e.g. by folding it around the stem portion 62 once or multiple times.

[0203] After the tensioning element 40 has also been fastened in such a manner at another location to a further mounting plate 30, two mounting plates 30 are connected to one another via the tensioning element 40.

[0204] Figure 11 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0205] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a tensioning element 40 to the mounting plate 30 is attached in one piece.

[0206] 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. 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 10. The head portion 60 has e.g. a length dP of 9 mm.

[0207] Figure 12 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0208] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a tensioning element 40 to the mounting plate 30 is attached in one piece.

[0209] 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 figures 3, 4 and 7. 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 60 and the stem portion 62 can be dimensioned as described with reference to figure 11.

[0210] Figure 13 shows a side sectional view of a part of a mounting plate 30 according to a further embodiment of the invention.

[0211] A portion of the two-dimensional base body 34 is illustrated, to which an alternatively configured fastening element 342 for fastening a tensioning element 40 to the mounting plate 30 is attached in one piece.

[0212] The mounting plate 30 in the embodiment shown in figure 13 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 figures 3, 4 and 7. The punched tab was then deformed in the manner of a hook, thus forming a fastening tab 61. The tab extends at an obtuse angle in a direction perpendicular to the two-dimensional base body 34.

[0213] In figures 14 - 19, the two-dimensional base body 34 and the fastening elements 342 are designed purely by way of example as described with reference to figures 9 and 10. However, the mounting plate 30 can alternatively be designed as illustrated in figures 3 to 8 and 11 to 13 or as described in the context of figures 3 to 8 and 11 to 13.

[0214] Figure 14 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.

[0215] Figure 15 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.

[0216] 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. Figure 16 shows a side sectional view of the mounting plate 30 with the anti-slip device of figure 14. 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 tensioning element (not illustrated here, cf. figure 20) has been attached to 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.

[0217] Figure 17 shows a side sectional view of the mounting plate 30 with an alternative antislip device. A buckle 73 (a rigid additional part, or even a sealing 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.

[0218] Figure 18 shows a side sectional view of the mounting plate 30 with another alternative anti-slip device. In this case, a wedge 75 (a rigid additional part or the like) was inserted into the gap between the anchoring bracket 20 and mounting plate 30, wherein the mounting plate 30 is pressed into the insulation layer 12 and the snap-back is prevented.

[0219] Figure 19 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, the tensioning element 40 is 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.

[0220] Figure 20 shows a tensioning element 40 in the form of a metal wire 442 which is suitable for being used in a fastening set in accordance with the invention. The metal wire 442 is formed e.g. with a diameter of 1.2 mm. The metal wire 442 is mounted on a winding core 451 . The metal wire 442 can be easily transported and unwound. The length of the tensioning element 40 can be adapted directly on the building site. Alternatively, the tensioning element 40 can also be rolled up on a winding core 451 or can be provided uniformly cut to length in a dispenser or housing or, even further alternatively, in the composite.

[0221] Figure 21 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.

[0222] 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 fagade 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 21 is compatible with the previously described embodiments of the mounting plate 30.

[0223] Figure 22 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 21 , 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.

[0224] The anchoring bracket 20 illustrated in figure 22 differs from the embodiment illustrated in figure 21 substantially in the configuration of the toothed profile 242. The toothed profile 242 (illustrated in greater detail in figure 23) 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.

[0225] The advantages of the embodiment of figure 22 and figure 23 and also figure 24 reside in the combination with the slip-in window 325 of the mounting plate 30 which has been described in connection with figures 3 and 9. Reference can be made at this juncture to the statements made in this respect.

[0226] Fig. 24 shows a section of an anchoring bracket 20 according to a further embodiment of the invention. As described with reference to figures 22 and 23, the anchoring bracket 20 comprises the toothed profile 242 with the lug 243 facing the foot region 22 and the undercut 245. The supporting region 24 is provided below the toothed profile 242 with a grooved profile 247 which supports the clamping reception of the mounting plate 30.

[0227] Fig. 25 shows an anchoring bracket 20 which is designed as a rod-shaped fagade anchor with a foot region 22 which can be fastened to the wall region, and a preferably collinearly adjoining rod-shaped supporting region 24. The rod-shaped fagade anchor preferably comprises a metal core to transfer the load of the fagade cladding to the wall region and a glass fibre sheath to minimise heat bridges, in particular in the supporting region 24, for example, but this is not limiting to the invention. The foot region 22 is anchored in a bore in the wall region with or without dowels or a metal screen sleeve. The supporting region 24 is provided with a ribbed profile 25 which supports the clamping reception of the mounting plate 30.

[0228] Fig. 26 shows an anchoring bracket 20 which is designed as a hanger with a foot region 22 which can be fastened to a wall region and an adjoining supporting region 24, wherein the supporting region 24 comprises in this case a U-profile which can be displaceably received in a further U-profile or can displaceably receive a further U- profile. In order to adjust a longitudinal dimension of the anchoring bracket, rows 27 of holes are advantageously provided on each limb of the U-profile. After fitting the mounting plate 30 onto the supporting region 24 of the anchoring bracket 20, the mounting plate can be fixed in position by means of a split pin. The further U-profile can then be inserted to the required length and can be fastened to the supporting region 24 by means of a further split pin.

[0229] Figure 27 shows a wall portion 10 with anchoring brackets 20 fastened therein and two insulation elements 14 in a state which can be shown in one implementation of the method in accordance with the invention, or which can arise when using the fastening set in accordance with the invention. The grid pattern of the anchoring brackets 20 is generally determined by the structural requirements of the fagade cladding. The anchoring brackets 20 are illustrated in this case, purely by way of example but not limiting to the invention as described above with reference to figure 21 or 22, as L- shaped profiles and each have the foot region 22 and the 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.

[0230] 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 but are selected according to the necessary structural calculation. 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.

[0231] Figure 28 shows a state after the method in accordance with the invention has been carried out at a time after the state illustrated in figure 27. For a better overview, the individual insulation elements 14 are in this case no longer shown, otherwise the view corresponds to that in figure 27. 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 9, and optionally then protected against slipping, as described with reference to figures 3 and 4 or figure 14 to figure 19. In each case, two mounting plates 30 are connected to each other by means of one or more tensioning elements 40.

[0232] A preferred system is achieved when using linear tensioning elements 40, e.g. metal wires. The length of the tensioning element 40 used can be adapted directly on the building site. The tensioning element 40 is connected to the mounting plates 30, generally under tension, i.e. in a taut state, by means of the fastening elements 342 and is cut off at the end and finally fastened, e.g. by winding around, knotting or the like.

[0233] It is possible to connect the anchoring brackets 20 to one another either, as illustrated, vertically in a double zigzag (figure 28) or horizontally in a double zigzag (figure 29), wherein the tensioning elements 40 of four anchoring brackets 20 cross one another and form a net-like structure. This allows the fastening of the insulation elements to be firmly secured. Depending on the structural calculation, a variable design of the securing arrangement is possible.

[0234] Alternatively or in addition, it is possible e.g. to connect merely anchoring brackets 20 disposed horizontally next to each other and / or anchoring brackets 20 disposed vertically with respect to each other, cf. e.g. figure 32. Figure 30 shows an alternative image to figure 29, which can result after attaching the tensioning elements 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 tensioning elements 40, the anchoring bracket 20 prevents the mounting plate 30 from lifting off.

[0235] Figure 31 shows another alternative image which can result after attaching the tensioning elements 40 and mounting plates 30 to 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 mounting plates 30 described with reference to figure 3 were used. Each mounting plate 30 is fitted on an anchoring bracket 20 by means of its first receiving slot 326. The distances between the mounting plates 30 are bridged by the net 444. In the upper two rows of mounting plates 30, the net 444 is formed as a horizontal double zigzag pattern as described above. The net 444 covering the two lower rows of mounting plates 30 is formed by a horizontal single zigzag pattern.

[0236] As described above, the grid pattern of the anchoring brackets 20 is generally determined by the structural requirements of the fagade cladding. It has been demonstrated that the procedure illustrated in figure 31 is sufficient for samples with distances between the anchoring brackets 20 of up to 750 mm. For distances between the anchoring brackets 20 greater than 750 mm, further fixing can be achieved with additional mounting plates 30, as described hereinafter with reference to figures 32 and 33.

[0237] Figure 32 shows an alternative image to figure 31 which can result when carrying out the method in accordance with the invention. Located on the wall portion are four anchoring brackets 20 which are spaced too far apart from one another for the insulation layer 12 to be adequately held in position by the mounting plates 30 fastened thereto and the tensioning elements 40. Further mounting plates 30 have therefore been clamped under the net 444 so as to bridge the gap in each case. For this purpose, the anchoring spoke 360 of a mounting plate 30 was initially bent by 90° and inserted into an insulation element 14. For this purpose, the mounting plate 30 was placed approximately in the centre under a tensioning element 40. The other two spokes of the bridging device 364 were bent upwards and hooked into the previously tensioned net 444. By bending the two opposing spokes upwards, the insulation element 14 becomes secured in position via the tensioned net 444.

[0238] Figure 33 shows an alternative spanning arrangement. In the top row, two mounting plates 30 are bridged by means of a double spanning arrangement 446 by means of, in this case purely by way of example, the same tensioning element 40. By virtue of the fact that this also increases the contact pressure on the mounting plate 30, the spanned mounting plate 30 can serve as the end point for spanning of a still further spanned mounting plate 31.

[0239] Figure 34 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.

[0240] 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, are provided with mounting plates 30. A tensioning element 40, which extends from the first mounting plate 30 to the second mounting plate 30 and back, bridges the corner region 18. On the end side, the tensioning element 40 is fastened in each case to the fastening elements 342 of the two mounting plates 30. The tensioning element 40 is bent or is folded over the corner region.

[0241] What is not illustrated in the drawing is the possibility of arranging a mounting plate 30 on each of the two insulation elements 14 in such a way that the tensioning element 40 is guided over the respective bridging devices 364 in order to prevent the tensioning element 40 from cutting into the insulation layer 12, wherein the two mounting plates 30 preferably contact one another in the edge region. This structure offers the advantage that no further element is required and by virtue of the anchoring - described in conjunction with figure 3 - in the insulation layer 12, the latter is additionally secured in the corner region. Alternatively, an edge protection element, not illustrated, e.g. an edge protection bracket made of metal or synthetic material, can also be used in order to prevent the tensioning element 40 from cutting into the insulation layer 12.
