Description

[0001] Wall element with mounting part

[0002] The invention relates to a wall element, a wall arrangement comprising the wall element, and a method for providing the wall element.

[0003] Room-dividing wall elements are widely known. Using these wall elements, for example, an aesthetically pleasing separation of a hallway from a workspace can be achieved. Furthermore, the installed wall elements can also serve other purposes, such as preventing fire spread if the wall element is designed as fire-resistant glazing.

[0004] Fire-resistant glazing serves to protect people and objects on one side of the glazing from a fire on the other side. Typically, not only is smoke containment desired, but also at least a temporary heat barrier. Under normal operating conditions, however, fire-resistant glazing should function like a standard transparent glazing unit. One category of fire-resistant glass consists of at least two panes, usually transparent, with a fire-resistant coating sandwiched between them. This coating, also known as a fire-resistant interlayer or fire-resistant gel, may contain an intumescent, opacifying, heat-insulating, and / or cooling material. The material of the fire-resistant coating is, for example, an alkali polysilicate with the highest possible water content.Water-containing, organic, gel-like polymer hydrogels are also known as materials for fire-resistant coatings. These fire-resistant coatings have in common that they are transparent at room temperature, but become cloudy and / or foam up when exposed to heat, thereby exerting a cooling effect.

[0005] Alkali silicates are completely transparent under normal application conditions, but begin to become irreversibly cloudy and foamy at temperatures of approximately 80 °C. Such fire-resistant glazing can be produced by applying a thin layer of liquid alkali silicate to one side of a first pane and then drying it (see, for example, WO 2004 / 082933 A1). This drying step is complex and slows down the manufacturing process. A second pane is then bonded to the intermediate, or protective, layer of alkali silicate. WO 94 / 04355 A1 proposes a method in which the fire-resistant layer can be produced by casting without drying. The fire-resistant layer of WO 94 / 04355 A1 is a polysilicate formed from alkali silicate and at least one hardener, the starting material of which is flowable and suitable for casting into cavities.In this process, a chamber formed by the space between two (or more) panes is sealed around its perimeter. A penetration is created in the seal, and the chamber is filled through this penetration with the liquid or paste-like material of a fire-resistant coating. The penetration is then sealed, and the fire-resistant material is allowed to harden into a fire-resistant coating.

[0006] The room-dividing wall elements typically have a frame surrounding the edges. This frame improves stability but can also affect the visual appearance of the wall element.

[0007] A particularly aesthetic appearance is achieved when the wall element is frameless or at least largely frameless. However, the wall element must be attached to the surrounding room opening. To reduce visible fixing elements at the edge of the wall element, one option is to use only one or two mounting elements at the top and / or bottom edge of the wall element (see, for example, WO 2013 / 104946 A1).

[0008] US 2008 / 196333 A1 discloses a panel fastening for securing a panel within a window opening.

[0009] EP 3 438 394 A1 discloses a frameless fire-resistant insulating glazing system.

[0010] Often, the opening into which the wall element is to be installed has unevenness in the contact area with the element, making alignment during installation difficult. Furthermore, achieving uniform alignment of multiple wall elements relative to each other to create a cohesive wall arrangement is also challenging. Therefore, it is desirable to provide an aesthetically pleasing and mechanically reliable wall element that allows for easy adjustment both during and after installation.

[0011] The object of the present invention is achieved according to the invention by a wall element according to claim 1. Preferred embodiments are described in the dependent claims. A wall arrangement according to the invention, comprising the wall element according to the invention, and a method for providing the wall element are described in further independent claims.

[0012] The wall element according to the invention comprises at least one disc assembly, wherein the disc assembly has a lower edge, an upper edge opposite the lower edge, and two side edges, and at least one fastening element, wherein the at least one fastening element comprises at least: a U-shaped clamp that engages the lower edge and / or the upper edge of the disc assembly with two legs, wherein the U-shaped clamp has a projection arranged on the side of one of the legs of the U-shaped clamp facing away from the disc assembly, and the projection has at least two first bores; a holder having a side flank and a contact plate connected to each other and arranged perpendicular to each other, wherein the contact plate has at least three first slot-shaped openings and the side flank has a first recess that can receive the projection of the U-shaped clamp.wherein at least one of the first slot-shaped openings is arranged parallel to the lower and upper edges of the disc assembly and at least one of the first slot-shaped openings is arranged perpendicular to the lower and upper edges of the disc assembly, and wherein a first fixing means is inserted into each of the at least three first slot-shaped openings, and a mounting plate having at least two second slot-shaped openings, wherein a second fixing means is inserted into each of the at least two second slot-shaped openings, which engages in one of the first bores of the projection of the U-shaped clamp.

[0013] The design of the fastening element according to the invention allows the wall element to be easily adjusted in three spatial directions during installation. Furthermore, it also allows for easy adjustment of the position after installation for maintenance purposes. The separate design of the U-shaped clamp, the bracket, and the mounting plate enables a high degree of flexibility in the arrangement of the panel assembly with respect to the building opening and, if the wall element is part of a wall assembly, with respect to other elements of this wall assembly, such as another wall element according to the invention, a generally known wall element, and / or a door. Accordingly, for example, unevenness in the building opening can be easily compensated for, and, if necessary, the parts of the wall assembly can be easily aligned with each other, resulting in an aesthetically pleasing overall appearance.Furthermore, the wall element features maximum transparency thanks to its minimalist fastening design, while achieving high mechanical strength.

[0014] The lower edge of the disc assembly is defined as the edge closest to the building's floor surface when installed in a building opening, while the upper edge is the edge of the disc assembly that, when installed, has the greatest distance from the floor surface and is closest to the nearest floor slab or ceiling structure of the building. The disc assembly also has two side edges, preferably parallel to each other, which connect the upper and lower edges. Furthermore, the disc assembly has two outer surfaces formed by the disc surfaces facing the environment. In a disc assembly according to one embodiment comprising two discs, a first disc represents an outer surface of the disc assembly facing the environment and an inner surface facing a spacer.The first disk is connected to the inner surface of a second disk via the spacer, while the surface of the second disk facing away from the spacer can represent an outer surface of the disk assembly. If the disk assembly comprises further disks according to an embodiment, this structure applies analogously, whereby all disk surfaces bordering an intermediate space are defined as inner surfaces, and the two outer surfaces of the disk assembly are formed by the first disk and one of the further disks.

[0015] According to a preferred embodiment, the disk arrangement comprises at least a first disk, a second disk, and at least one spacer circumferentially separating the disks. Alternatively, the disk arrangement can also be designed as a monolithic disk (single disk). The materials used for the monolithic disk can be the same as those used for the first disk or the second disk, as described below.

[0016] If, according to one embodiment, the pane arrangement comprises exactly two panes and a spacer arranged circumferentially between the panes, these panes and the spacer form a gap which is optionally filled with a fire-resistant layer or a gas. If, according to another embodiment, the pane arrangement comprises exactly three panes, the third pane is attached to the first or second pane via a further spacer, with a further gap formed between the third pane, the spacer, and the first or second pane, respectively, which is optionally filled with a fire-resistant layer or a gas. The pane arrangement can also comprise more than three panes, with further gaps forming analogously, which are optionally filled with a fire-resistant layer or a gas.

[0017] According to the invention, the U-shaped clamp with two legs encompasses the lower and / or upper edge of the disc assembly. This means that the two legs extend from the respective edge along a portion of the outer surfaces of the disc assembly. This is advantageous for further increasing the contact area between the U-shaped clamp and the disc assembly and the associated mechanical stability. In one embodiment, the two legs extend from the respective edge by at least 15 mm, preferably at least 20 mm, and more preferably at least 23 mm, along the outer surfaces of the disc assembly.

[0018] According to the invention, a projection is arranged on the side of one of the legs of the U-shaped clamp that faces away from the disk assembly. Here, "facing away from the disk assembly" also means "facing away from the outer surface of the disk assembly".

[0019] According to the invention, the projection has at least two first bores. Preferably, these at least two first bores are symmetrically arranged and centrally located with respect to the height of the projection. This enables a particularly stable attachment of the fastening element to the disc assembly.

[0020] In one embodiment of the present invention, the projection of the U-shaped clamp is flush with the surface of the side flank of the holder that faces away from the disc assembly. Here, "facing away from the disc assembly" also means "facing away from the outer surface of the disc assembly." This allows for a particularly stable connection between the U-shaped clamp, the holder, and the mounting plate.

[0021] According to the invention, the U-shaped clamp has a projection. In one embodiment, the projection is formed in one piece, so that the at least two first bores are openings in a single surface. According to another embodiment, the projection is formed in multiple parts, so that each of the at least two first bores is embedded in a part of the projection. In this embodiment, the parts of the projection are arranged as islands on the U-shaped clamp.

[0022] Preferably, the U-shaped clamp is attached to the disc assembly by an adhesive. The adhesive is preferably applied in a liquid state and, due to its flowability, optimally fills any gaps between the outer surface and edge of the disc assembly and the U-shaped clamp. After the adhesive has cured, a particularly strong bond is achieved. At the same time, manufacturing tolerances of the U-shaped clamp can be compensated for. Preferably, the materials mentioned for the spacer are used as the adhesive.

[0023] According to the invention, the bracket has a side flank and a contact plate. The bracket is preferably formed in one piece. The side flank and the contact plate are connected to each other and arranged perpendicular to one another. When the wall element is installed, the contact plate is arranged substantially parallel to the lower and upper edges of the pane assembly, and the side flank is arranged substantially parallel to the outer surfaces of the pane assembly. "Substantially" here means that a deviation of up to 4 degrees is permissible. The contact plate comprises the contact surface between the wall element and the building opening.

[0024] According to the invention, the contact plate has at least three first slot-shaped openings, wherein at least one of the first slot-shaped openings is arranged parallel to the lower and upper edges of the disc assembly and at least one of the first slot-shaped openings is arranged perpendicular to the lower and upper edges of the disc assembly. This arrangement of the first slot-shaped openings allows for flexible attachment of the wall element to the building opening, thus compensating for unevenness in the installation environment, and also facilitates the absorption of impact loads against the wall element in the installed state, particularly through attachment via the at least one first slot-shaped opening that is arranged parallel to the lower and upper edges of the disc assembly.

[0025] Preferably, at least one of the first slot-shaped openings is arranged parallel to the lower and upper edges of the disc assembly in the center of the contact plate when viewed from above. This design allows for particularly effective absorption of impact loads on the wall element. Furthermore, preferably, at least one of the first slot-shaped openings is arranged on both sides of the center, perpendicular to the lower and upper edges of the disc assembly, extending outwards from the center. This design enables a particularly strong attachment of the wall element to the building opening. According to one embodiment, each of the first slot-shaped openings has a width of at least 5 mm, preferably at least 7 mm, and more preferably at least 9 mm.According to one embodiment, each of the first slot-shaped openings has a length of at least 13 mm, preferably at least 16 mm, more preferably at least 19 mm.

[0026] According to the invention, a first fixing element is inserted into each of the at least three first slot-shaped openings. The first fixing element establishes a connection between the wall element and the building opening. Preferably, the building opening is provided with bores at the selected locations for this connection, which are preferably fitted with dowels or fastening screws, so that each first fixing element engages with a counterpart when installed. This results in a particularly stable connection between the wall element and the building opening.

[0027] In one embodiment, the contact plate of the holder has a notch centrally located at at least one end along its longitudinal direction when viewed from above. This notch can be used, for example, to align the contact plate during installation of the wall element using a line laser, a chalk line, or a marker.

[0028] According to the invention, the side flank has a first recess that can receive the projection of the U-shaped clip. In the installed state, the first recess receives the projection of the U-shaped clip. In a preferred embodiment, the first recess is at least 1.2 times, preferably at least 1.3 times, larger than the projection of the U-shaped clip when viewed from above. This allows for easy spatial adjustment of the first recess and the projection relative to each other. In a preferred embodiment, the first recess is rectangular. This allows for a particularly flexible fastening perpendicular to the building opening and along the upper or lower edge of the pane assembly.According to the invention, the fastening element comprises a fastening plate having at least two secondary slot-shaped openings, each of which contains a secondary fixing element that is inserted into one of the first bores of the projection of the U-shaped clamp. The fastening plate thus connects the disc assembly with the U-shaped clamp to the holder. The slot-shaped design of these secondary slot-shaped openings offers an advantageous adjustment option for fastening the fastening plate and the U-shaped clamp. In a preferred embodiment, the at least two secondary slot-shaped openings of the fastening plate are arranged perpendicular to the contact plate of the holder. In another embodiment, each of the secondary slot-shaped openings has a width of at least 3 mm, preferably at least 4 mm, and more preferably at least 5 mm.According to one embodiment, each of the second slot-shaped openings has a length of at least 13 mm, preferably at least 16 mm, more preferably at least 19 mm.

[0029] According to one embodiment of the present invention, the first recess in the side flank of the bracket is arranged centrally in the top view, and at least one second bore is arranged on each of two opposite sides of the side flank, outside of the first recess. The preferred central arrangement allows for a particularly mechanically stable fastening. The second bore is suitable for receiving the adjusting screw described below.

[0030] In a preferred embodiment of the invention, the at least two second slot-shaped openings in the mounting plate are arranged centrally in plan view, with at least one second recess located outside each of them. Preferably, an adjusting screw is inserted through one of the second recesses into one of the second bores of the bracket. In a preferred embodiment, each of the second recesses is at least 1.3 times, preferably at least 1.5 times, and even more preferably at least 2 times larger than one of the second bores. This allows for easy spatial adjustment of the second recesses and the second bores relative to each other. In a preferred embodiment, each of the second recesses is rectangular. This allows for particularly easy adjustment of the mounting perpendicular to the building opening and along the upper or lower edge of the pane assembly.

[0031] In its installed state, the adjusting screw preferably makes contact with the U-shaped bracket. By tightening (tightening) or loosening (loosening) this adjusting screw, the angle (tilt angle) between the outer surface of the disc assembly with the U-shaped bracket and the building opening can be adjusted. Preferably, the adjusting screw is a setscrew. This allows for particularly easy angle adjustment.

[0032] The fastening element is preferably made of a metallic material, for example aluminum or steel, particularly stainless steel. Alternatively, the fastening element can also be made of plastic, for example polypropylene. Suitable materials and manufacturing processes for providing the fastening element with these materials are known to those skilled in the art.

[0033] The first and second fixing means according to the invention are not particularly restricted and can be selected by a person skilled in the art from conventional fixing means. According to one embodiment, the first fixing means can be a first screw or a first anchor. Preferably, the first fixing means is a first screw. Preferably, the second fixing means is a second screw. The type of the first fixing means depends on the properties of the material of the building opening and can be selected accordingly by a person skilled in the art. Examples of the first fixing means include countersunk screws (such as M8 x 15 mm (ISO 10642)), countersunk wood screws (such as 8 x 50 mm (DIN 97)), and Fischer anchors (such as SXRL 10 x 100 mm). Examples of the second fixing means include countersunk screws (such as M5 x 10 mm (ISO 10642)).

[0034] In one embodiment of the present invention, the wall element further comprises a block arranged between the U-shaped clamp of the fastening element and the mounting bracket of the fastening element. Preferably, the wall element includes such a block when the fastening element is designed to secure the wall element to the floor of a building opening. The block bridges any gap that may exist between the wall element with the U-shaped clamp and the mounting bracket, ensuring that the wall element rests stably on the mounting bracket. The thickness of the block is selected to ensure that the gap is bridged. According to one embodiment, the block is fire-resistant. For the purposes of the invention, "fire-resistant" means that the block remains mechanically stable at temperatures above 600 °C. This is particularly advantageous if the wall element is fire-resistant glazing.Preferably, the block comprises at least one material made of silicon carbide, aluminum oxide, zirconium dioxide, and mullite. According to one embodiment, the wall element further has at least two covers that conceal the at least one fastening element from both sides of the disc assembly. This results in an aesthetically pleasing overall appearance. According to one embodiment, a cover can be designed to extend along the entire width of the disc assembly.

[0035] According to one embodiment, the pane assembly comprises at least one spacer. The spacer in the pane assembly serves to maintain the panes at a defined and constant distance from one another across the wall element. Furthermore, the spacer defines the cavity between the panes, into which a fire-resistant layer is optionally arranged, this fire-resistant layer being protected from environmental influences, or into which a gas is optionally introduced to form insulating glazing. Depending on the type of wall element and the manufacturing process, the spacer can also serve to seal the cavity during manufacturing. For the application of, for example, a flowable fire-resistant compound, the panes can first be spaced around their perimeter by the spacer, with an opening left in the surrounding spacer frame through which the flowable fire-resistant compound is poured.The spacer seals the gap. In this embodiment, after the gap is filled, the fire-resistant compound hardens and the opening of the spacer frame is closed.

[0036] Suitable spacers for use in wall elements are known to those skilled in the art; for example, spacers comprising polyvinyl chloride (PVC), injection-moldable thermoplastic spacers, metallic spacers, and / or glass fiber reinforced plastics (GFRP) are used. Glass fiber reinforced plastic spacers are available as prefabricated profiles that are bonded to the adjacent glass pane surfaces using a sealant. Preferably, the spacer is an injection-moldable thermoplastic spacer. Injection-moldable thermoplastic spacers, also known as TPS spacers, are known to those skilled in the art and generally comprise sealing materials such as polyisobutylene and butyl rubber. With these spacers, no separate sealant or adhesive is required for installation, as the spacer itself already consists of a suitable sealing material.These spacers can be applied directly to the panel. Thermoplastic spacers are also advantageous due to their comparatively high mechanical flexibility, which allows them to compensate for differing thermal expansion rates among the individual components of a wall element. Furthermore, thermoplastic spacers, due to their extrusion process, offer a high degree of flexibility in shaping the spacer strand. The metallic spacers can be made of materials such as aluminum or stainless steel.

[0037] The spacer is preferably an injection-moldable thermoplastic spacer comprising a sealing material from the group of hot melt adhesives, particularly preferably from the group of butyl-based hot melt adhesives, especially butyl rubber and / or polyisobutylene. The butyl polymers described in EP 1179113 B1, containing 40 wt.% to 65 wt.% polyisobutylene, 10 wt.% to 25 wt.% carbon black, and 10 wt.% to 40 wt.% of a filler, have proven particularly advantageous and can be applied directly to the discs using an extrusion die.

[0038] The spacer can be positioned flush with the edges of the discs at the top, bottom, and side edges of the disc assembly, or it can be recessed from the disc edges towards the center of the disc assembly. In the latter case, an outer gap is formed between the discs, bounded by the discs and the spacer, and open to the surroundings on a fourth side.

[0039] Preferably, the spacer is set back from the nearest edge towards the center of the surface by an amount of 2 mm to 50 mm, particularly preferably by 2 mm to 30 mm, and especially by 3 mm to 22 mm, along the bottom edge, the top edge, and the side edges. This creates a circumferential outer gap between the first disk, the second disk, optionally further disks, and the spacer.

[0040] Preferably, the wall element has an outer cavity between the panes, which includes a secondary sealant adjacent to the spacer. The secondary sealant, also referred to as a sealant, fills the outer cavity between the first and second panes across its entire width. This secondary sealant causes the first and second panes to bond together, thus improving the mechanical stability of the wall element according to this embodiment. The secondary sealant preferably comprises a polymer or silane-modified polymer, particularly preferably organic polysulfides, silicones, room-temperature curing silicone rubber, high-temperature curing silicone rubber, peroxide-curing silicone rubber and / or addition-curing silicone rubber, polyurethanes and / or butyl rubber.Such materials have very good adhesion to glass, so the secondary sealant primarily serves to bond the panes together. The thickness of the outer seal made of secondary sealant is preferably 2 mm to 30 mm, more preferably 5 mm to 10 mm. Preferably, the secondary sealant is flush with the circumferential edge of the first and second panes.

[0041] Preferably, the disc arrangement includes a sealing strip comprising intumescent material at the lower edge, the upper edge, and / or one or both side edges. Sealing strips known to those skilled in the art and commercially available can be used. According to one embodiment of the present invention, the sealing strip comprises a tube in which the intumescent material is arranged. The tube is preferably made of a fire-resistant material. For example, the tube can be made of a fiberglass fabric. Preferably, the intumescent material is arranged in the tube in strip form along the direction of extension of the tube and / or on the inner surface of the tube. In the event of a fire, the intumescent material foams up and thereby seals the gap between the wall element and the building opening.The preferred arrangement of the intumescent material within the tube ensures that, upon activation, the foamed material is held within the tube, thus guaranteeing a long-lasting seal and insulation in the event of a fire. In another embodiment, the sealing tape can comprise wires surrounding the intumescent material. In a further embodiment, the sealing tape can comprise a sealing material surrounding the intumescent material. Like the tube mentioned above, the wires and the sealing material serve to hold the intumescent material against the foamed material upon activation, thus ensuring a long-lasting seal and insulation in the event of a fire. According to one embodiment, the sealing tape can be attached to the disc assembly using an adhesive layer.

[0042] According to one embodiment, the wall element is a fire-resistant glazing unit. In this embodiment, the pane assembly comprises at least a first pane, a second pane, and at least one spacer separating the panes around their perimeter, and further, at least one fire-resistant layer arranged in the space between the panes and the spacer. Various intumescent or non-intumescent fire-resistant materials known to those skilled in the art can be used as the fire-resistant layer. Preferably, the fire-resistant layer comprises polysilicates and / or hydrogels. The alkali silicates mentioned in EP 2516568 B1 and the hydrogels described in DE 102005018842 A1 are suitable examples. Alkali silicate gels according to EP 3224045 A1 have proven to be particularly advantageous.

[0043] According to another embodiment, the wall element is an insulating glass unit. In this embodiment, the pane arrangement comprises at least a first pane, a second pane, and at least one spacer separating the panes around their perimeter, and furthermore a gas introduced into the space between the panes and the spacer. Preferably, the gas is a noble gas, more preferably argon or krypton, or air. Argon and krypton advantageously reduce the heat transfer coefficient in the insulating glass cavity, while air allows for simpler handling and more cost-effective manufacturing. Manufacturing methods for insulating glass units are known to those skilled in the art.

[0044] According to another embodiment, the disc assembly is a panel. In this embodiment, the disc assembly can comprise at least the first disc and the second disc described above, and a plate that separates the first and second discs from each other. Alternatively, the disc assembly can comprise at least a first sheet and a second sheet, and a plate that separates the first and second sheets from each other. The first sheet and the second sheet can independently comprise steel or stainless steel. The plate can, for example, be a fire-resistant board, such as a cement-bonded silicate fire-resistant building board.

[0045] In one embodiment of the wall element, the pane arrangement comprises at least three panes, wherein a third pane is attached to the first pane or the second pane via a spacer and is spaced apart from it, forming an intermediate gap.

[0046] The first and / or second pane, as well as any further panes, such as a third pane, preferably contain glass, particularly preferably quartz glass, borosilicate glass, soda-lime glass, and / or mixtures thereof. The panes may also comprise thermoplastic polymeric panes. Thermoplastic polymeric panes preferably comprise polycarbonate, polymethyl methacrylate, and / or copolymers and / or mixtures thereof.

[0047] According to one embodiment, the first and second discs have a thickness of 1 mm to 50 mm, preferably 1 mm to 10 mm, and particularly preferably 3 mm to 8 mm, with the two discs also being able to have different thicknesses. Additional discs, such as a third disc, of the wall element preferably also have thicknesses within these ranges.

[0048] The first pane, the second pane, and optionally further panes, such as the third pane, can be made of tempered safety glass, thermally or chemically tempered glass, float glass, extra-clear low-iron float glass, colored glass, or laminated safety glass containing one or more of these components. The panes can have any other components or coatings, for example, low-E coatings or other solar control coatings.

[0049] In a preferred embodiment, the wall element comprises at least two fastening elements according to the present invention. In this embodiment, preferably at least one of the fastening elements is arranged at the lower edge of the panel assembly, while at least one of the fastening elements is arranged at the upper edge of the panel assembly. In a further preferred embodiment, the wall element comprises at least four fastening elements according to the present invention. In this embodiment, preferably at least two of the fastening elements are arranged at the lower edge of the panel assembly, while at least two of the fastening elements are arranged at the upper edge of the panel assembly. This provides particularly good support for the panel assembly.In cases where at least two fastening elements are arranged on the lower or upper edge of the panel assembly, it is preferred that, in at least one of these arrangements, the at least two fastening elements are connected to each other via a web. Connecting the fastening elements to each other via the web facilitates the uniform alignment and support of the wall element. According to a preferred embodiment, the web connects the contact plates of at least two fastening elements to each other. This embodiment facilitates the installation of the wall element.

[0050] In one embodiment, a diamond-shaped opening is arranged centrally in the web when viewed from above. This diamond-shaped opening can be used, for example, to align the fastening element during installation of the wall element using a line laser, a chalk line, or a marker.

[0051] Another aspect of the invention relates to a wall arrangement comprising at least one wall element according to the invention. In one embodiment, the wall arrangement comprises at least two wall elements according to the invention. In another embodiment, the wall arrangement comprises at least one wall element according to the invention and at least one general wall element. According to one embodiment, the wall arrangement comprises at least one wall element according to the invention and at least one door. The space between the butt joints of adjacent elements of the wall arrangement can be filled with conventional means, such as a silicone sealant or a fire-resistant sealant. In one embodiment of the present invention, the sealing tape described above can be used.

[0052] Another aspect of the invention relates to a method for providing the wall element according to the invention, comprising the following steps:

[0053] Provision of the mounting bracket for the fastening part,

[0054] Securing the contact plate of the bracket in a building opening by inserting initial fixing elements into at least the first three slot-shaped openings of the contact plate,

[0055] Provision of the disk assembly and the U-shaped clamp, wherein the U-shaped clamp encompasses the lower edge and / or the upper edge of the disk assembly with two legs,

[0056] Arrangement of the disc assembly with the U-shaped clamp in relation to the contact plate of the holder, such that the projection of the U-shaped clamp is positioned in the first recess of the holder, provision of the mounting plate,

[0057] The mounting plate is attached to the U-shaped clamp by inserting second fixing elements through the second slotted openings of the mounting plate into the first bores of the projection of the U-shaped clamp.

[0058] The features described with regard to the wall element according to the invention also apply to the method according to the invention and vice versa.

[0059] In one embodiment, the steps of the method are carried out in the order mentioned above. Alternatively, it is also possible, for example, to provide the holder, the disc assembly, the U-shaped clamp, and the mounting plate at the beginning of the method.

[0060] According to the invention, the disc assembly with the U-shaped clamp is arranged in relation to the contact plate of the bracket such that the projection of the U-shaped clamp is positioned in the first recess of the bracket. In one embodiment, a gap is located between the disc assembly with the U-shaped clamp and the contact plate. In another embodiment, the gap can be bridged with a block. This is particularly advantageous when the fastening element secures the wall element to the floor of a building opening. This allows the wall element with the U-shaped clamp to rest stably on the bracket.

[0061] The spacer is preferably in the form of a sealant automatically injected around the perimeter of a gap between the panes, for example, using a commercially available double-glazing system. Preferably, a bead of sealant is first applied around the perimeter of the first pane, then the second pane is placed on top of the sealant and the assembly is pressed together. Alternatively, the first and second panes could be held in position, for example, by means of a suction device, while a sealant is injected around the perimeter of the gap between the panes using a nozzle on a robot arm. As a further alternative, the sealant can also be prefabricated as a bead or hollow profile and inserted into the gap between the panes.

[0062] After the sealant is applied, the first and second panes are pressed together with the sealant bead between them. Suitable presses, for example for the production of insulating glass units, are known to those skilled in the art. After pressing the assembly, a blank is formed in which the circumferential sealant bead acts as a spacer between the panes. Alternatively, for special shapes, such as model panes, or special sizes, production can be carried out manually.

[0063] According to one embodiment, the wall element has a fire-resistant layer, preferably a flowable fire-resistant compound applied to the space between the first pane, the second pane, and the spacer. For this purpose, at least one opening is preferably provided in the surrounding spacer through which the fire-resistant compound can be poured into the space between the panes. The blank filled with flowable fire-resistant compound is then subjected to a curing step, causing the compound to harden. This involves, for example, polymerization, resulting in the formation of a fire-resistant gel within the chamber. This process is applicable to all fire-resistant compounds that can be processed in a flowable form during the production process and cure in a subsequent step.Alternatively, the fire-resistant compound can also be applied in flowable form to one of the panes, dried on it, and laminated between the panes after placing another pane on top.

[0064] Various types of fire-resistant glass are known in the prior art, which utilize flowable fire-resistant compounds, such as aqueous alkali silicates or aqueous hydrogels. Upon curing, these compounds form a fire-resistant layer that foams up, becomes cloudy, and provides heat insulation and / or cooling when exposed to heat. Preferably, the flowable fire-resistant compound comprises at least alkali silicates and at least one hardener. After curing, a polysilicate fire-resistant layer is formed. Such polysilicate fire-resistant layers exhibit good transparency under normal conditions, while in the event of a fire, they provide heat protection by becoming cloudy and / or foaming up. Foaming fire-resistant layers are also known as intumescent fire-resistant layers and are familiar to those skilled in the art.

[0065] Preferably, a secondary sealant is introduced into the outer space between the panes on the surface of the circumferential spacer facing the environment, either before or after filling with the fire-resistant compound or with gas in the case of insulating glazing.

[0066] In one possible embodiment of the method, the wall element comprises further panes extending beyond the first and second panes, which, analogous to the connection of the first and second panes, are also connected to these panes via a circumferential bead of sealant. In this way, two or more chambers are formed in the spaces between the panes, which are to be filled with fire-resistant compound or gas.

[0067] After the fastening element is attached, the edges of the wall element are preferably provided with a sealing tape, more preferably comprising an intumescent material. The invention is explained in more detail below with reference to drawings and exemplary embodiments. The drawings are purely schematic representations and not to scale.
