Description

Technical area

[0001] The invention relates to a screwless suspension bracket and a screwless suspension system for building elements, in particular for facade elements such as bricks in ventilated facade constructions. In particular, it relates to a screwless, modular suspension system that simplifies assembly, increases flexibility, and optimizes storage and maintenance. Background of the invention

[0002] Conventional systems for fastening building elements, especially brick facades, typically require screws or other mechanical fasteners, which are labor-intensive and time-consuming to install, expensive due to the high quantities required, and inflexible when it comes to adjustment or disassembly. Furthermore, screw connections make building elements such as the bricks of a brick facade too rigid and are insufficiently resistant to the energy generated by high wind and storm loads, for example. Furthermore, screws can cause corrosion and impair the aesthetics of the facade. Therefore, there is a need for a system that enables simple, screwless installation while offering flexibility in storage and maintenance.

[0003] It is therefore an object of the invention to provide a suspension bracket and a suspension system which enables secure, screwless fastening of building elements, in particular facade elements, while ensuring flexible assembly and easy maintenance and is characterized by high stability and low storage and logistics costs.

[0004] This object is achieved by a suspension bracket according to claim 1 and by a suspension system according to claim 12. The system utilizes, among other things, a suspension bracket suspension mechanism that is guided through an opening in the rear side of a wall of a support profile, so that the suspension projections protrude from the front side of the support profile for the components. Furthermore, the suspension bracket utilizes a pressure profile for locking the suspension bracket and the component to be suspended. Summary of the invention

[0005] The present invention describes a suspension system for a building element, in particular facade elements such as bricks of a brick facade, which does not require screws and enables flexible assembly and storage.

[0006] In one aspect, the invention provides a screwless suspension bracket for a component, comprising: - at least one floor area; - at least one suspension projection for receiving a building element, in particular a facade element, preferably a brick, which is connected to the base surface in such a way that a suspension device, preferably a hook element, for the suspension bracket is formed between the suspension projection and the base surface; - and the base further comprises at least one pressure profile for locking the suspension bracket.

[0007] In a further aspect, the invention provides a screwless suspension system as a substructure for a building element, in particular a brick of a brick facade, comprising: - at least one holding profile, in particular at least one rail, which is suitable for receiving the aforementioned suspension bracket; - the aforementioned suspension bracket; characterized in that the suspension bracket is designed to be hookable from behind through an opening in a wall of the holding profile by means of the hanging device, preferably the hook element.

[0008] The suspension of the suspension bracket from the rear side of a support profile through an opening is referred to in the invention as a snap-click mechanism. The suspension device of the suspension bracket, preferably the hook element, comes to rest by hooking into the opening in the wall of the support profile and can be released again by unhooking. The at least one suspension device, preferably a suspension lug, for a component protrudes freely from the support profile.

[0009] The snap-click mechanism securely and removably attaches the suspension bracket to a support profile, such as a support rail. The weight of the structural element, such as the facade element, additionally locks the suspension bracket in place. The system is designed to be mounted horizontally or vertically, remain flexible, and accommodate high static loads.

[0010] The retaining profile is preferably made of an omega profile or a T-profile with special punching. The system is scalable and can be configured as a four-point suspension ("four-point bracket"). Barbs, counterpressure hooks, or additional brackets can be used for additional security.

[0011] The material to be used is a metal or alloy. The preferred material is an aluminum alloy EN AW-5083.

[0012] The system according to the invention comprises the following technical advantages: Screwless fastening: Structural elements such as bricks of a brick facade are securely fixed by the suspension system according to the invention without the need for screws. This is possible thanks to the suspension points (e.g., the hook elements of the suspension device) of the suspension bracket through an opening in the wall of a support profile from the rear.

[0013] The Snap Click mechanism enables a quick, secure but also removable connection of the suspension brackets to a support profile such as a support rail of a substructure for house facades.

[0014] By suspending the suspension brackets through the wall of the support profile from behind through an opening, the static advantages of the support profile are used to fix the building elements, such as bricks, to the rigid support profile from behind, which increases the stability of the substructure.

[0015] A 4-point suspension system for the respective suspension trestles is preferred. This provides additional stability and flexibility during installation.

[0016] Due to a preferably standardized suspension device of the suspension brackets, e.g. the suspension nose XY, the suspension bracket and the system are manufacturer-independent and can be used for a variety of facade elements.

[0017] The additional at least one pressure profile in the base of the suspension bracket presses the component itself against the suspension device when the component is suspended, increasing its stability. At the same time, the component presses the suspension bracket itself against the support profile via the at least one pressure profile, strengthening, stabilizing, and securing it. This locks the components in the suspension system according to the invention without rattling, thus preventing movement and noise from the components, such as the brick. The suspension bracket itself is secured against falling out, which generally increases safety.

[0018] The structural design of the suspension bracket and the suspension system as a whole allows for efficient storage of components. This is due, among other things, to the fact that the suspension brackets are universally applicable for a wide variety of facade elements and can be modularly suspended from a support profile according to requirements. The design of the suspension bracket and support profile allows for horizontal or vertical arrangement of building elements using the same raw materials. Detailed description of the invention

[0019] In light of the above disclosure, the invention includes, among others, the following numbered embodiments and associated technical effects and advantages: 1. Screwless suspension bracket for a building element, in particular a facade element, comprising: - at least one floor area; - at least one suspension projection for receiving the structural element, in particular the facade element, which extends away from the base surface and is connected to the base surface in such a way that a suspension device for the suspension bracket is formed between the suspension projection and the base surface.

[0020] A key advantage of the suspension bracket according to the invention is that it does not need to be fixed to a support profile with screws or other fastening devices. Thanks to its aforementioned design, the suspension bracket is self-suspending in a support profile via the suspension device. This means that no additional fastening devices such as screws, nails, or rivets are required. Likewise, the self-suspending design means that no significant or even no tooling is required to attach the suspension bracket to a support device.

[0021] According to the invention, any type of suspended wall or facade cladding can be used as building elements, such as facade panels, bricks, wall stones, metal plates, etc.

[0022] In a preferred embodiment, the base surface is present only once and formed in one piece. In an alternative embodiment, the base surface can also be composed of multiple parts. Cutouts and / or openings can be incorporated into the base surface.

[0023] The suspension projection is the actual element for suspending the building element, especially a facade element. The suspension projection can take a variety of forms, provided it fulfills the secure suspension function for a building element, preferably a facade element. Preferred designs are a suspension lug or a suspension hook.

[0024] The suspension device connects the suspension bracket to the support profile, e.g., a support rail, in a releasable manner. The suspension device can take a variety of forms, provided it ensures secure insertion, hooking, and suspension of the suspension bracket in the support profile. Preferred designs of the suspension device are a hook, a barb, a groove, or a recess. 2. Screwless suspension bracket according to embodiment 1, wherein the base surface further comprises at least one pressure profile for locking the suspension bracket and / or the structural element, in particular the facade element.

[0025] In one embodiment, the pressure profile can be punched out of the base of the suspension bracket.

[0028] A substructure for a house facade is the supporting framework installed between the actual building wall and the visible facade cladding. It serves to securely attach the facade cladding (e.g., wood, metal, fiber cement panels) to the building.

[0029] Functions of a substructure: a. Load transfer: This transfers the weight of the facade panels and any wind or impact loads to the building structure. b. Ventilation: In many cases, it allows air circulation behind the facade, which prevents moisture damage to the wall (especially in the case of rear-ventilated facades, VHF). c. Leveling: This compensates for unevenness in the wall and ensures a flat mounting surface. d. Thermal insulation: An insulating layer is often placed between the substructure and the wall.

[0030] Materials for substructures: • Wood: Classic for facades with wood cladding. • Metal (aluminum, steel): Very durable, dimensionally stable.

[0031] The rearward attachment of the suspension bracket to a retaining profile makes it possible to dispense with fastening devices such as screws, nails, or rivets. This reduces or even eliminates the need for tools, reduces the number of craftsmen and personnel required for the facade cladding, is significantly more cost-effective, can be prefabricated, and is easy to handle. 13.

Screwless suspension bracket according to embodiments 1 to 11 and screwless suspension system according to embodiments 12 to 24, wherein the material is an EN AW-5083 material.

[0032] The suspension system according to the invention can be individually adapted for manufacturers of facade elements. The facade elements are fixed by a pressure profile that prevents the suspension brackets from rattling in the holding profile, such as a support rail. The suspension bracket is designed so that it can be locked against falling out and offers screwless fastening using, for example, a “snap click” or “snap-fit” mechanism. This mechanism enables components, preferably facade elements, to be easily inserted / clicked into place. Inventively, the suspension brackets are suspended from the rear, i.e. behind the holding profile, through an opening in the holding profile. The static advantages of the design are used to guarantee stable and secure fixing of building elements. In particular, a four-point suspension ensures that the load is evenly distributed and the system can respond flexibly to movements, e.g.due to wind or thermal expansion. The system is also designed to enable efficient warehousing by systematically prefabricated, organized, and easily accessible components. The modular approach of the inventive system, consisting of a retaining profile, a suspension bracket, and, if necessary, additional suspension brackets on the front and / or back of the retaining profile, allows for a wide variety of approaches for horizontal or vertical alignment of the building elements, e.g., a facade wall made of individual bricks.

[0044] Can be used for panel systems, tiles, and various facades. Character description

[0045] The Fig. Figures 1 to 19 show examples of the suspension bracket and suspension system according to the invention in various configurations, as well as corresponding support profiles. The figures are schematic representations and are not to be understood as limiting, but rather as examples. Further variations and alternatives will undoubtedly be apparent to those skilled in the art. Fig. Figure 1 shows an exemplary suspension bracket according to the invention in a perspective top view as a four-bracket variant (1). This comprises a base surface (2) from which four suspension projections (3) extend (four-bracket), each of which is connected to the base surface in such a way that it forms a suspension device (4); in this case, a suspension hook that can be hooked rearwardly, for example, into an omega profile as the substructure of a facade cladding (see the figure descriptions below; the omega profile is not shown here). This is achieved entirely without screw connections or other holding devices.The suspension bracket shown further comprises four pressure profiles (5), which, on the one hand, press against the structural element suspended in the suspension projections (3), stabilizing the fastening. On the other hand, the pressure exerted by the suspended structural element locks the suspension bracket itself to its retaining profile by means of the suspension devices (4). However, a slight play remains between the suspension bracket and the retaining profile, ensuring that this substructure is not rigid but remains slightly flexible, thus advantageously cushioning wind loads, for example, in terms of energy efficiency.

This is done entirely without screw connections or other holding means. The suspension bracket (1) shown further comprises four pressure profiles (5), which, on the one hand, press against the structural element suspended in the suspension projections (3) (structural element not shown), thus stabilizing the fastening, and, on the other hand, lock the suspension bracket (1) itself against its holding profile (6) by means of the suspension devices (4) through the pressure of the suspended structural element.However, a slight play remains between the suspension bracket (1) and the retaining profile (6) in such a way that this substructure is not rigid but remains slightly flexible, and can therefore absorb wind loads, for example, in an energetically advantageous way. Fig. 5 further shows the front side (8a) of the Omega profile as an exemplary holding profile, and the back side (8b) of the Omega profile, in which the suspension bracket (1) is hung from the rear via the openings (7) of the Omega profile (6) - without the use of screws or other holding means.

The suspension projections (3) and the pressure profiles (5) protrude through suitable openings in the support profile, e.g., the Omega profile (6), and can come into contact with the building element, such as a wall brick. Fig. 7 shows the suspension system according to the Fig. 5 and Fig. 6 in plan view, for example with the front side (8a) of the retaining profile, here the omega profile (6).

Fig. 8 shows the suspension system according to the Fig. 5, Fig. 6 and Fig. 7 in the bottom view, for example with the back (8b) of the retaining profile, here the Omega profile (6). The reference symbols have the same meanings as in the Fig. 1 and Fig. 5.

This is clearly visible from the visible base (2) of the suspension bracket (1). The suspension projections (3) and the pressure profiles (5), not visible here, protrude through suitable openings (7) in the support profile, e.g., the omega profile (6), and can come into contact with the building element, such as a wall brick, and secure it and / or lock the suspension bracket (1) in the support profile (6).

Fig. Figure 10 shows an exemplary suspension bracket according to the invention in a perspective top view as a two-bracket variant (9). This comprises a base surface (2) from which two suspension projections (3) extend (two-bracket), each of which is connected to the base surface in such a way that it forms a suspension device (4); in this case, a suspension hook that can be hooked rearwardly, for example, into an omega profile as the substructure of a facade cladding (see the figure descriptions below; the omega profile is not shown here). This is achieved entirely without screw connections or other holding means.The suspension bracket shown further comprises two pressure profiles (5), which, on the one hand, press against the structural element suspended in the suspension projections (3), stabilizing the fastening. On the other hand, the pressure exerted by the suspended structural element locks the suspension bracket itself to its retaining profile by means of the suspension devices (4), or they are simply snapped or pushed into the retaining profile itself. However, a slight play remains between the suspension bracket and the retaining profile, such that this substructure is not rigid but remains slightly flexible, and can thus advantageously absorb wind loads, for example, in terms of energy.
