Description

[0001] Thermally insulating bracket for facades

[0002] Description

[0003] Technical area

[0004] The invention relates to a thermally insulating bracket for fastening a projection, e.g. a facade panel system, to a supporting structure such as an external wall of a building.

[0005] State of the art

[0006] US 2004 / 123550 A1 (Hartmann) discloses a building panel fastening system with improved energy efficiency and fire protection properties. The panels are connected to a structural angle bracket. The angle bracket has a base and a head section made of aluminum. A web connects the base and head sections. The web can also be made of metal or it can be formed by a thermally insulating panel. A composite material consisting of continuous strand mat and glass fiber roving with a phenolic resin matrix is ​​used as the thermally insulating material.

[0007] A thermally insulated facade construction is known from EP 2'180'1 15 B1 (Wagner System AG). The construction uses a connecting piece between the facade and the supporting structure, which has a base section, a head section, and a spacer plate. The base section and head section are made of bent-back aluminum or stainless steel sheet. The spacer plate is thermally insulating and made of glass-fiber-reinforced plastic (GRP). It essentially bridges the space between the supporting structure and the facade. The disadvantage of the known systems is that they are either thermally insulating but not fire-resistant, or fire-resistant but with little thermal insulation.

[0008] Description of the invention

[0009] The object of the invention is to provide a bracket belonging to the technical field mentioned at the outset for fastening a projection to a supporting structure, which bracket is both thermally insulating and fire-resistant.

[0010] The solution to the problem is defined by the features of claim 1.According to the invention, the thermally insulating holder comprises the following components: a) a base part having a base surface for stable support on the supporting structure and a spacer plate holder perpendicular to the base surface; b) a spacer plate made of a thermally insulating material, wherein the spacer plate has an inner end region and an outer end region and wherein the spacer plate has at least two through holes at its inner end region; c) at least two pin connections, each of which pierces one of the at least two holes and creates a mechanically load-bearing connection between the spacer plate holder of the base part and the spacer plate; d) wherein the spacer plate is a laminated material consisting essentially of muscovite mica paper layers to ensure high tensile strength of the laminated material and of a silicone resin binder as a matrix for firmly bonding the mica paper layers.

[0011] Features a) to c) are known from EP 2'180'115 B1.

[0012] The base section is designed to be securely attached to the supporting structure, for example with a dowel anchor. The base surface ensures stable alignment. The spacer plate holder is a section of the base section designed to hold the spacer plate. The spacer plate should be essentially perpendicular to the base surface and thus to the supporting structure (e.g. building wall). The spacer plate is the core element for thermal insulation. The material should have a thermal conductivity of less than 1 W / mK. Good values ​​are in the range of 0.25 W / mK and less. The material is essentially non-flammable, meaning it does not burn even when exposed to flames. The material is preferably stable up to 500 °C. The holes in the inner end area can have any shape, but a round shape is preferred.

[0013] The at least two pin connections, each of which pierces one of the at least two holes, are intended to clamp and hold the spacer plate as a whole.

[0014] Advantages

[0015] The laminated material according to the invention is mechanically resilient, thermally insulating, and non-combustible. This has the advantage that the bracket can be easily used for buildings where the facade structure must be thermally insulating but must not contain any flammable materials (e.g., high-rise buildings).

[0016] Furthermore, the inventive bracket has the advantage that it can be easily adapted to different distances during production. It is sufficient to insert a suitably cut spacer plate between the standardized foot section and head section. This allows different mounting lengths to be created using one type of head section and foot section.

[0017] Furthermore, the material according to the invention has the advantage that it can be processed quickly and easily in terms of production technology.

[0018] The laminate is produced, for example, by impregnating a large number of muscovite mica paper layers (as known, for example, from DE 11 02 548 B; General Electric) with the silicone resin binder and then bonding them together with heat in a press to form a composite material. The resulting laminate consists essentially only of mineral muscovite mica and silicone resin binder. These two components make up at least 99% by weight of the laminate's composition. The remaining components are typically natural impurities in the muscovite mica and any traces of chemical substances from the manufacturing process. In the following description - beginning with number 2 - various particular embodiments of the invention are explained.

[0019] Version 2: at least 85 wt% muscovite mica

[0020] According to a particular embodiment of the invention, the muscovite mica paper layers constitute at least 85% by weight of the laminate. The proportion of silicone resin binder is advantageously no more than 15% by weight of the laminate. Traces of chemical substances from the manufacturing process in the laminate should be as minimal as possible and, for example, not exceed 1% by weight of the laminate.

[0021] The laminate may contain small amounts of other components, e.g. potassium silicate, which increases the tensile strength of muscovite mica paper (as known, for example, from DE 11 02 548 B; General Electric).

[0022] Deviating from the above embodiment, laminates containing less muscovite mica paper, e.g., 80 wt.%, are also within the scope of the invention. Accordingly, the proportion of silicone resin can be, for example, around 20 wt.%. Because mica paper has a significantly higher heat resistance than silicone resin, reducing the mica paper content will tend to lower the heat resistance of the laminate.

[0023] Version 3: At least 2 wt.% silicone resin

[0024] According to a particular embodiment of the invention, the silicone resin binder makes up at least 2% by weight of the laminate. Preferably, the silicone resin content is as low as possible, while at the same time, the mineral content in the laminate is as high as possible.

[0025] It has been shown that a laminate with a silicone resin content of at least 8 wt.% and a maximum of 12 wt.% exhibits a particularly good combination of tensile strength, heat resistance, and low thermal conductivity. The tensile strength, for example, is approximately 180 MPa and the tensile modulus is approximately 62 GPa (according to ISO 527). The thermal conductivity is approximately 0.18 W / mK (ISO 8301). The operating temperature is approximately 500°C, and the short-term maximum operating temperature is approximately 800°C.

[0026] This amount of binder ensures that the muscovite mica papers are reliably bonded together. This allows the laminate to achieve the desired mechanical strength (tensile strength).

[0027] In principle, the laminate should contain as little silicone resin as necessary. This means the mineral content (mica component) should be as high as possible.

[0028] Deviating from the above embodiment, silicone resin contents of less than 2% by weight are also within the scope of the invention.

[0029] Design type 4: Distance plate has L to D in the range 5-100

[0030] According to a particular embodiment of the invention, the spacer plate has a length-to-thickness ratio between 5 and 100, in particular at least 10. This means that the spacer plate is thin. The smaller the cross-section of the spacer plate, the lower the heat dissipation through the plate. Consequently, high insulation values ​​can be maintained with the support.

[0031] Deviating from the above embodiment, length-to-thickness ratios greater than 100 are also possible within the scope of the invention. However, the mechanical stability of the spacer plate is then rather low, requiring more brackets per square meter of facade. This can lead to a suboptimal insulation value for the entire building structure. This effect is particularly noticeable when high insulation requirements for the facade are met.

[0032] Design type 5: Constant thickness of the spacer plate in the range 2 - 10 mm

[0033] According to a particular embodiment of the invention, the spacer plate has a constant thickness. This is preferably in the range of 2 mm to 10 mm. At a thickness of less than 2 mm, the stable length of the spacer plate becomes too short. The maximum distance between the supporting structure and the canopy that can be bridged by the bracket is then too short. For thick insulation layers of, for example, 200 mm, such thin spacer plates are no longer very effective. In contrast to the above embodiment, the invention also includes spacer plates that are significantly thicker than 10 mm. These can be used to bridge large distances with mechanical stability. However, the heat dissipation is then increased due to the relatively large cross-section. The thickness of the insulation layer is usually less than approximately 220 mm. The gain in mechanical stability is then achieved at the cost of increased heat dissipation.

[0034] Design type 6: rectangular spacer plate

[0035] According to a particular embodiment of the invention, the spacer plate has a substantially rectangular outer contour. Such a shape typically results in optimal utilization of the material. This means that the consumption of spacer plate material for an insulated building envelope is advantageously low. Furthermore, such plates are easy to manufacture by cutting a piece from a long, strip-shaped sheet of material.

[0036] Deviating from the above embodiment, the invention also includes spacer plates with a different outer contour, such as a trapezoidal outer contour.

[0037] Design 7: Spacer plate has recess

[0038] In a special embodiment of the invention, the spacer plate has a recess at its inner end. This recess allows for a centered hole to be provided in the base section. The centered hole serves to fix the base section to the supporting structure using a dowel anchor. The screw head of the dowel anchor is accessible thanks to the recess in the spacer plate. The recess can be wedge-shaped or rectangular, for example.

[0039] In contrast to the above embodiment, it may also be advantageous if the spacer plate forms a closed rectangular surface (i.e., closed except for the holes for the pin connections to the base). Such spacer plates are particularly easy to manufacture.

[0040] It is also not excluded that two or more recesses are provided in the spacer plate, e.g. to save weight or for special mounting purposes.

[0041] Embodiment 8: U-profile on the foot part According to a special embodiment of the invention, the spacer plate holder of the foot part forms at least one U-profile. The U-profile has a slot width that corresponds to the thickness of the spacer plate, so that the spacer plate can be pushed into the U-profile during production of the holder. The at least two pin connections penetrate the U-profile (i.e. both flanks of the U-profile). The thickness of the U-profile and spacer plate are preferably matched to one another in such a way that the spacer plate is clamped to both flanks of the U-profile when the pin connection is attached. In the present embodiment, a single continuous U-profile can be provided, or, for example, two aligned U-profiles can be provided.

[0042] Deviating from the above embodiment, it is also within the scope of the invention that a flat connection is provided instead of the U-profile, in the sense that the spacer plate is fixed on one side to a plate-shaped end of the foot part.

[0043] Version 9: Headboard

[0044] According to a particular embodiment of the invention, the bracket has a head section with a connecting piece as a further component. The connecting piece is mechanically and load-bearing-fastened to the outer end area of ​​the spacer plate with at least two pin connections.

[0045] The head section is used to attach the facade system to the bracket. This bracket design allows the manufacturer to adapt the bracket to different facade systems. When ordering the bracket, the customer specifies which facade system the bracket should be adapted to. The manufacturer can then combine a standardized base section with a spacer plate and attach the appropriate head section to the outer end of the spacer plate.

[0046] In contrast to the above embodiment, the invention also encompasses brackets consisting only of a base section and a spacer plate. If the manufacturer does not offer head sections, it is up to the user to decide how to attach the facade system to the spacer plate. The facade manufacturer can then provide their preferred fastening components as the connection to the spacer plate.

[0047] Design 10: U-profile on the headboard. According to a special design of the invention, the connecting part of the headboard forms at least one U-profile that surrounds the outer end area of ​​the spacer plate on both sides. This U-profile is adapted to the thickness of the spacer plate in the same way as the U-profile of the footboard. It is also penetrated on both sides by a pin connection that connects the headboard to the spacer plate. By enclosing the spacer plate on both sides, the U-profile ensures a mechanically very strong connection to the spacer plate.

[0048] In contrast to the above embodiment, head sections that essentially consist of a flat plate or a T-profile are also within the scope of the invention. In this case, a cost-effective solution can be created with a one-sided connection (i.e., the spacer plate and head section are placed sideways against each other and connected with a continuous pin connection).

[0049] Design 11: Adapter element on the headboard

[0050] In a particular embodiment of the invention, the head section has at least one adapter element for attaching the extension to the bracket. The adapter element has, for example, the form of a clamping finger, a slot, or a C-profile. The adapter element can also be a specifically positioned hole for screwing in a support of the façade substructure. This means that the head section is physically adapted to the façade substructure. The adapter element can, for example, be designed so that a support can be temporarily clamped before being permanently fixed.

[0051] Deviating from the above embodiment, head parts which are essentially designed as simple rectangular plates (but at least with holes for the pin connection to the spacer plate) are also within the scope of the invention.

[0052] Design type 12: Riveted joints

[0053] According to a particularly preferred embodiment, the pin connections are designed as rivets. If the base or head section forms a U-shaped profile, it is irrelevant which side the rivet head is on. In contrast to the above embodiment, pin connections in the form of a screw and nut or other clamping means are also within the scope of the invention.

[0054] Design 13. Foot part mirror-symmetrical

[0055] In a particular embodiment of the invention, the base section is mirror-symmetrical with respect to a plane perpendicular to the base surface. In particular, the openings for the dowel anchors are mirror-symmetrical with respect to the center plane defined by the spacer plate. This is advantageous for the statics of the bracket.

[0056] In contrast to the above embodiment, non-mirror-symmetrical base parts are also within the scope of the invention. In practice, it will often be necessary to design individual brackets asymmetrically to accommodate a particular feature of the facade. For example, L-shaped base parts are often required for a facade. However, if the bracket is not mirror-symmetrical and requires an off-center opening for the dowel anchor, the aim is to keep the asymmetry as small as possible to prevent the resulting increase in moments on the dowel anchor from becoming excessive.

[0057] Design type 14: extruded aluminum profile

[0058] In a particular embodiment of the invention, the base section is formed from an extruded aluminum profile. A single base section can thus be easily manufactured by cutting a piece of the required length from a long profile.

[0059] In an analogous manner, the head part can also be made from an extruded aluminum profile piece.

[0060] The bracket according to the invention can be assembled with minimal technical effort. The base section, head section, and spacer plate are prepared by cutting a piece from a long profile or a long strip of material. Holes for the dowel anchors are then drilled in the base section. If necessary, certain parts of the extruded profile may also be shortened. Where necessary, adapter elements (e.g., a slot, a hole for a pin connection) are attached to the head section. The holes for the pin connections are drilled in the spacer plate. Finally, the parts are connected to each other with the required number of pin connections.

[0061] Deviating from the above embodiment, the invention also includes head and foot parts formed from a strip of sheet steel, as is known per se from the prior art cited at the outset.

[0062] Structure with supports

[0063] A further object of the invention is to provide an insulated building with a facade that is both thermally insulated and fire-resistant on the outside.

[0064] According to the invention, the stated object is achieved by a structure comprising a supporting structure, in particular a building wall (e.g., made of concrete or brick), external insulation on the supporting structure (e.g., a mineral insulation mat on the building wall), and a projection, in particular a facade panel system, and a thermally insulating mounting according to the invention. The mounting anchors the projection to the supporting structure.

[0065] Further advantageous embodiments and combinations of features of the invention emerge from the following detailed description and the entirety of the patent claims.

[0066] Short description of the drawings

[0067] The drawings used to explain the embodiment show:

[0068] Fig. 1 shows a preferred embodiment of the holder according to the invention with a full-surface spacer plate;

[0069] Fig. 2 is a schematic representation of a cross section of a spacer plate according to the invention as shown in Fig. 1;

[0070] Fig. 3 shows a second preferred embodiment of the holder according to the invention with a spacer plate with a recess; Fig. 4 shows a schematic representation of a structure with the holder according to the invention.

[0071] In principle, identical parts in the figures are provided with identical reference symbols.

[0072] Ways to implement the invention

[0073] The bracket 3 shown in Fig. 1 consists of a base section 4, a spacer plate 9, and a head section 12. The base section 4 and the spacer plate 9 are mechanically connected via two pin connections 8.1, 8.2. Similarly, the spacer plate 9 and the head section 12 are connected via two pin connections 8.3 and 8.4. The bracket 3 is provided in this form, for example, by the manufacturer and mounted on the building by the construction worker on site (see Fig. 4).

[0074] The foot part 4 is made essentially of an extruded aluminum profile according to design type 14.

[0075] The base section has a base plate 5 in the form of a long rectangular strip, which is vertically oriented when the bracket 3 is mounted. In this orientation, a first hole 6.1 is provided at the upper end of the base plate 5 and a second hole 6.2 is provided at the lower end of the base plate 5. The upper hole 6.1 is an elongated hole with a vertical longitudinal axis; the lower hole 6.2 is an elongated hole with a horizontal longitudinal axis, which allows for precise adjustment of the base plate 5 to the supporting structure.

[0076] Between the two holes 6.1, 6.2, a spacer plate holder 7 is formed in the vertical direction (assembly orientation), which is perpendicular to the base surface 5.1 and protrudes away from the base plate 5. According to embodiment 8 of the invention, it forms a U-profile 7.1. For this purpose, two strips are provided on the base plate 5 (opposite the base surface 5.1), which protrude perpendicularly from the base plate and are spaced apart from each other. Between the two spaced strips (which form the flanks of the U-profile 7.1), a receiving space for the inner end region 9.1 of the spacer plate 9 is formed. Each of the opposing strips has two holes aligned to receive a through-pin of the pin connection 8.1, 8.2. The two pin connections

[0077] 8.1 and 8.2 penetrate the U-profile on both sides according to design type 8.

[0078] The bracket 3 in Fig. 1 is, in accordance with embodiment 13, mirror-symmetrical with respect to a vertical plane perpendicular to the base surface 5.1. In particular, the entire bracket is mirror-symmetrical with respect to the vertical center plane defined by the spacer plate 9 (the directions mentioned here refer to the installation orientation). This has the advantage that the vertical loads absorbed by the bracket are optimally transferred into the supporting structure via the dowel anchors. In other words: For a given load capacity of the dowel anchors, the greatest possible load can be absorbed. With an asymmetrical design of the bracket, moments can arise that require a reduction in the load per bracket.

[0079] Fig. 2 shows a schematic cross-section through the spacer plate 9. It has a rectangular contour (cf. Fig. 1) in the sense of embodiment 6 with an inner end region 9.1 and an outer end region 9.2. The inner end region 9.1 is accommodated in the U-profile 7.1 of the base part 4. The width of the U-profile essentially corresponds to the thickness of the spacer plate 9, so that the inner region of the spacer plate lies flush between the flanks of the U-profile. Two holes 10.1 are provided in the inner end region 9.1 for the two pin connections 8.1, 8.2, which pierce the spacer plate (they are located one behind the other when viewed in Fig. 2). The diameter of the holes 10.1 is matched to the diameter of the pin of the pin connection, so that the hole and pin are essentially flush and the pin can engage all muscovite mica paper layers.

[0080] As schematically shown in Fig. 2, the spacer plate 9 is a laminated material composed of many thin muscovite mica paper layers 11 (also called muscovite mica foils). The individual muscovite mica paper layers consist primarily of mineral mica of the muscovite type. Muscovite is chemically defined by the following molecular formula:

[0081] K AI2[AISi3Oio(OH)2] Since muscovite mica is a natural product, unavoidable mineral impurities are always present in muscovite mica paper. However, these impurities have no relevant influence on the properties of muscovite mica paper, which are crucial for the invention: fire resistance, mechanical stability, and thermal conductivity.

[0082] The muscovite mica papers have a film thickness in the range of, for example, 0.3 - 0.6 mm. For a spacer plate with a thickness of, for example, 5 - 6 mm, 10 - 20 layers are pressed together. A silicone resin acts as a matrix and binder between the muscovite mica paper layers. Considered as a whole, the laminate consists almost exclusively of muscovite mica paper and silicone resin. These two components typically make up at least 99% by weight of the laminate.

[0083] For the spacer plate 9 in Fig. 1, for example, a composition of approximately 90 wt.% muscovite mica paper and approximately 10 wt.% silicone resin binder is chosen. This corresponds to design type 2 and also design type 3.

[0084] The spacer plate 9 in Fig. 1, for example, has a length of 200 mm (measured from the inner end to the outer end), a width of 80 mm (measured in the vertical direction of the mounting orientation), and a thickness of 5 mm. This results in a length-to-thickness ratio of 40 (corresponding to designs 4 and 5).

[0085] As further indicated in Fig. 2, there are two holes 10.1 in the outer end area 9.2 (they are located one behind the other when viewed in Fig. 2). These serve to attach the head section 12 shown in Fig. 1. The head section 12 is formed from an extruded aluminum profile piece. A U-profile 14 is formed on this as a connecting part 13, the width of which is adapted to the thickness of the spacer plate 9 in a manner as described in connection with the U-profile 7.1 of the spacer plate holder 7. The head section 12 thus corresponds to design 10.

[0086] The head section 12 has a panel section 15, at whose inner end is the U-profile 14 and at whose outer end is an adapter element 16.1 in the form of a C-profile. The C-profile runs vertically in the assembly orientation, i.e., along the panel section 15. The C-profile serves to fix the facade substructure (see Fig. 4). A further adapter element 16.2 is a horizontal slot into which a support of the facade substructure can be inserted. Thus, the head section 12 implements design type 11.

[0087] Fig. 3 shows another embodiment. The mount again consists of a base section 18, a spacer plate 9, and a head section 12. The three components are connected via four pin connections 8.1 - 8.4.

[0088] The pin connections each have a pin element (e.g., bolt) and a clamping element (e.g., rivet, nut). They are preferably riveted connections according to design type 12.

[0089] The base part 18 differs from the base part 4 of the embodiment of Fig. 1 in that it has two U-profiles 22.1, 22.2 arranged one above the other in alignment in the assembly orientation. The upper U-profile 22.1 extends to the upper edge of the base plate 21, while the lower U-profile 22.2 extends to the lower edge of the base plate 21. The hole 6.3 is located between the two U-profiles 22.1, 22.2. The hole 6.3 is located in the center of the base plate 18. Overall, the base part 18 is mirror-symmetrical to the vertical center plane of the base part 18 (embodiment 13).

[0090] The spacer plate 19 has a rectangular outer contour with a length of, for example, 200 mm and a width of, for example, 180 mm. It also has a recess 23 at the inner end. This creates a free space in the spacer plate 19 in front of the hole 6.3. The recess allows a screw to be inserted through the hole 6.3 when attaching the bracket to the building wall. In the top view (i.e., viewed perpendicular to the plate plane), the spacer plate 19 has two arms or supports in the inner end. The recess is a combination of a rectangle and a triangle (wedge shape). The thickness of the spacer plate is, for example, 8 mm.

[0091] The laminate from which the spacer plate 19 is made contains approximately 88 wt.% muscovite mica paper and approximately 12 wt.% silicone resin binder, with traces of other substances from the manufacturing process of no more than 1 wt.% being neglected. This corresponds to design type 2 and also design type 3.

[0092] The head section 20 has a U-profile 24 with two through holes (not shown) for the pin connections 8.3, 8.4. A plate section 25 is connected to the bridge section of the U-profile 24. This plate section has adapter elements, namely holes 26.1, 26.2, and a clamping finger 26.3. The clamping finger 26.3 assists with assembly by clamping a support profile until it is screwed tight.

[0093] The head section 20 is not mirror-symmetrical with respect to the vertical plane (spacer plate plane). Rather, the plate section 25 is slightly offset from the center, so that the support profile, which is held by the clamping finger 26.3, lies in the plane of the spacer plate 19. The head section as a whole forms a quasi-H-shaped profile.

[0094] Fig. 4 schematically shows how a projection 30 is attached to a supporting structure 2, resulting in an externally insulated building construction. The inventive brackets 28.1, 28.2 are attached to the concrete wall 27, which is an exterior wall of the building, with anchor bolts. In the present example, the base of the brackets 28.1, 28.2 is equipped with only one hole for an anchor bolt.

[0095] Once the brackets 28.1, 28.2 are fixed in their intended locations, external insulation 29 (e.g., in the form of rock or glass wool) is laid on the concrete wall 27. The external insulation 29 has a thickness of 180 mm, for example. In the present example, the brackets 28.1, 28.2 are largely recessed into the external insulation. Only the outer end of the head section with the adapter elements is visible. Next, the substructure 30 of the facade is suspended from the brackets 28.1, 28.2. In the present example, horizontally running beams 30.1, 30.2 are inserted into the horizontal slots (cf. Fig. 1, adapter element 16.2) of the head sections and fixed in place. Subsequently, further parts of the substructure (e.g., vertical beams) are attached to the beams 30.1, 30.2. Finally, the facade panels (not shown) are suspended from the substructure.

[0096] In summary, the described examples can be modified in a variety of ways. In particular, the base section can be adapted almost infinitely to the specific structural features of the individual case. While clamping the spacer plate on both sides using a U-profile offers particular advantages in terms of mechanical load-bearing capacity, it is not mandatory. Depending on requirements, the spacer plate can be just long enough to be completely embedded in the building's insulation layer. However, it can also easily protrude from it and bridge the air space in a ventilated facade.

[0097] The head section is designed to facilitate easy installation of the façade substructure. Since there are a wide variety of façade constructions, the bracket according to the invention can be adapted to the various variants.

[0098] The spacer plate holder on the base section can be formed very simply by a plate part (e.g., a leg of an L-shaped base section). Holes for attaching the spacer plate are provided in this plate part, for example. List of reference symbols:
