Abstract

The invention relates to a transparent safety panel 1 for producing a resistant flush butt joint glazing 2 having at least two panes 44 and a profiled receiving section 11. The two panes 44 are arranged at a distance (D) to each other and substantially parallel to each other. The safety panel 1 has a joint end face 15 and a mounting end face 16 which extends perpendicularly from the joint end face 15 of the safety panel 1. The mounting end face 16 can be mounted in the frame and allows the safety panel 1 to be fixed in the frame. The profiled receiving section 11 is arranged between the mutually spaced panes 44 and in the process in an edge region in the vicinity of the joint end face 15. The profiled receiving section 11 forms an open groove up to the joint end face 15. The joint end face 15 of the safety panel together with the groove can also be called the connection face or the butt joint face. An additional safety panel can be connected to the safety panel 1 without additional frames in a flush manner via the connection face. The connection can be produced via an insert element 10 which is arranged in the grooves of adjacent flush safety panels 1, thus forming a resistant butt joint glazing 2.

Description

BUMPER JOINT GLASS

The invention relates to the field of resistant butt joint glazing. It relates in particular to a security panel and a set for the production of a frameless, flush butt joint glazing and a butt joint glazing with free edges and an insert element for use in a butt joint glazing according to the preamble of the corresponding claims.

Flush-mounted fire-resistant glazings with monolithic embodiments or insulating glass designs are known from the prior art. Such "butt-joint" glazings or butt joint glazings consist of a number of individual glazing units that are connected flush to each other. "Butt-joint glazings are able to form a visually appealing, flush-mounted glazing with fire protection function, but are sufficient such glazing does not meet the requirements for increased safety, such as anti-glare glazings of resistance class RC1-RC6 (EN 1627: 201 1), bullet resistance according to EN 1063: 2009 or blast resistance according to EN 13541: 2012. With the help of an anti-attack glazing of resistance class RC1-RC6, a perpetrator with simple additional tools, such as a saw and a percussion tool -or an additional power tool, such as Electric drill, do not penetrate or break within nominativ fixed times in the object in which the flush-mounted glazing is installed.

Of course, safety glazings of, for example, resistance class RC1-RC6 (according to EN 1627: 201 1) are known from the state of the art. Such safety glazings are mounted on four sides and consist of single-layer or multilayer glass-PVB laminates or glass-polycarbonate laminates, as shown for example in EP 1 194673, DE 20 2012 012285 or WO 2008/110021. Such glazings could previously only be used on four sides in correspondingly reinforced frame profiles and breakthrough-proof or burglar-resistant. As a result, resistant, burglary-resistant safety glazings have a circumferential four-sided mounting of the individual glazing units. Due to the width of the usually specially reinforced frame profiles, this four-sided bearing has an architecturally unattractive and clumsy effect and thus does not correspond to flush glazing or butt joint glazing.

For example, class P6B to P8B glazing of the EN 1627: 2011 standard describes an "attack-inhibiting glazing with breakthrough resistance." The test method attempts to produce a square breakthrough with an edge length of 400 mm using an ax between 30 and more than 70 times.

From the prior art, flush, two-sided mounted glazings with free edges or bump edges, so-called butt joint glazing, known, for example, EP 1 194673. In such glazes succeeds the experienced offender (burglar) so far with the appropriate tool through the attack on The edge of the glass that is not encircled in a frame profile, ie the free butt edge, provides relatively quick access to the object. The mechanical attack on the supposedly weaker joint between two adjacent panes is obvious as the weak point of only two-sided mounted glazing. J -

From the prior art, such as EP 1020605, glass wings without outer frame with circumferential support and / or edge termination element are known. Furthermore, a fire protection wall is known from DE 19933400, which is modularly constructed from sub-elements. Each sub-element has a circumferential frame made of profiles. The undercut frame can receive a connecting element. The connecting element is suitable for a point-by-point connection. DE3714629 discloses a facade wall of a building. The facade wall with outwardly projecting profile beam. The profile support is selectively screwed in the end with a holder between two panes. FR2662739 describes a disk assembly with an undercut circulation frame.

It is an object of the invention to provide a double-jointed butt joint glazing with free butt edges, which is designed as a flush glazing, without projecting from the glazing surface, frame profiles, and the increased security in terms of attack, burglary, bullet and / or explosive effect allows so resistant.

This object is achieved by a safety panel and a set for the production of a robust, flush-fitted butt joint glazing with free edges, as well as a butt joint glazing with the features of the corresponding claims.

The security panel is essentially transparent. Transparent in this context means translucent or translucent, ie transmitting light. In other words: the safety panel is translucent or translucent. Frameless means in the context of the invention that the individual glazing units, so security panels are not circumferentially enclosed in a frame profile, but two-sided or on the outside of the building opening on three sides, so not four-sided, are not stored circumferentially in a frame. Therefore, individual, adjacent safety panels in the joint joint glazing on a free edge and are held only on two sides in a frame. However, the butt joint glazing has resistant, in particular burglar-resistant properties. Resilient in the sense of the invention means that there is a break-through, bullet-drop and / or explosive-effecting property. The butt joint is located between the adjacent safety panels of the butt joint glazing. The butt joint is arranged substantially between the butt edges and / or butt-end faces of the adjacent safety panels of the butt joint glazing.

The safety panel for the production of a resilient, flush-jointed butt joint glazing has at least two substantially transparent plates, namely a first plate and a second plate, and a reinforcing profile. The reinforcing profile can also be referred to as a receiving profile. The two plates are spaced apart by a distance (D). The two plates are arranged substantially parallel to each other. The safety panel has a shock end face and a bearing end face extending substantially at right angles from the front end face of the safety panel. The storage front can be stored in a frame, also called outer frame, and allows a fixation of the security panel in the frame or in the building opening. Adjacent to the front face, another safety panel can be placed to form butt joint glazing. The outer frame may protrude from the plane of the flush joint glazing and may be located at the outer edge of the resilient butt joint glazing.

The security panel and / or the plate is / are a surface element which has two substantially parallel large outer surfaces, which are also called flat sides. The circumferential surface areas of the security panel or the plate between the flat sides are referred to in the present text "end faces", but can also the terms "edge" or "narrow side" of a Security panel or a plate can be used. In this case, the end face has a smaller area than the flat sides, and an extension of the end face perpendicular to the large areas, ie the flat sides, corresponds to the thickness of the security panel or the panel. An edge region of the security panel and / or the plate, which may be arranged in a frame, may also be referred to as a peripheral edge. The edge region is thus an area of the safety panel and / or the plate which is arranged near the end face. A rectangular safety panel or a rectangular plate has four end faces, while two opposite end faces may be referred to as bearing end faces, and the other two end faces may be referred to as a front face. The safety panel can be accommodated in the outer frame on the bearing end faces. The substantially perpendicular to the bearing end face extending Stossstirnseite with the receiving profile is adapted to receive an insert element.

The essentially flush butt joint glazing can be substantially flush on both sides, ie in relation to the two outer flat sides.

The receiving profile is arranged between the two spaced plates. The receiving profile is arranged in an edge region of the front end face of the security panel and the receiving profile has a receptacle, also open

Receiving profile side called on, which is open or open to this shock front side. This front face with the recording or the open

Shooting profile side can also be called connection side or shock side. On the connection side or shock side another security panel to the

Security panel flush with no additional frame between the two

Security panel are connected.

The receiving profile is set up so that the insert element is inserted or pushed along an insertion axis into the receiving profile can be inserted, that is inserted or inserted. The insertion axis is substantially perpendicular to the shock front. The insertion axis can run substantially parallel to the bearing end face. The insertion or insertion and / or positioning of the insert element in the / the receiving profile can be done essentially without effort. This means that the insert element can be easily inserted into the receiving profile. When inserting and / or inserting no frictional forces, spring forces, torques o.ä. be overcome. This allows easy manufacture of the resilient butt joint glazing.

The receiving profile can be configured substantially free of undercuts. In this way, the insert element can be easily inserted and / or inserted. This allows easy production of the resistant butt joint glazing. In contrast, in an undercut receiving profile, the correspondingly configured insert element would have to be inserted parallel to the front end face. This can lead to wedging or even damage to the panel and / or the insert element. The receiving profile can form an open groove towards the front face. The groove may have an undercut-free area for receiving an insert element, which supports an upgrading of the butt joint. The Hinterschnitssfreiheit may relate to the insertion axis. The receiving profile can be arranged along the butt joint, in particular the receiving profile can be arranged along the entire butt joint and / or butt end face, ie arranged over the entire length of the butt joint and / or butt end face. As a result, a continuous resistance of the butt joint can be obtained. Such continuous resistance can be the Prevent the formation of points of attack, which can occur, for example, at point anchorages.

The recording of the receiving profile may have over the entire length substantially the same cross-section. As a result, the insertion and / or insertion of the insert element over the entire length can be simplified.

The storage side can be free from the receiving profile, in particular free from a continuous receiving profile. On the storage side no insert element is inserted and / or inserted. In particular, the impact side is reinforced and the resilience of the butt joints is improved. The bearing in the outer frame can be independent of the butt joint resistance. The bearing end face can be stored in the outer frame. The mounting profile protects the edge area, ie the area near the front side, from damage, in particular in the event of a break-in, from bombardment and / or explosion and thus supports the protective function and resistance of the butt joint glazing or security panel. The first plate and / or the second plate may comprise or consist of a glass having resistant properties. The plate may be a thermally or possibly chemically tempered glass. As alternatives to glass panes based on silica, transparent carriers based on polymers (for example made of polycarbonates or poly-methyl methacrylate (PMMA; acrylic glass), partially crystalline "glasses" (ceramic glasses), borosilicate glasses or composite systems with glass panes and plastic carriers are also suitable the plate does not consist exclusively of glass material, it may for example also have a plastic (ie in particular a polymer, possibly with, for example, inorganic fillers), for example acrylic glass as part of a laminated glass exhibit. The first plate and / or the second plate or safety panel can comply with the product standard according to EN 1279.

The receiving profile can be permanently fixed in the edge region. As a result, the position of the receiving profile relative to the security panel can be precisely defined and the production of a butt joint glazing with free butt edges can be simplified.

The receiving profile can be fastened with a sealing compound in the edge region of the security panel. The sealant may be e.g. Silicone, polysulfide, polyurethane, other suitable construction adhesives and / or resins. As a result, the edge area near the front face of the security panel can be further reinforced.

The receiving profile may be arranged without contact to the first or second plate in the edge region of the security panel. This means that the receiving profile can be arranged so that it has no contact with the first or second plate. As a result, a heat transfer to the plates can be reduced and / or prevented. This can allow a reduction in the edge load. The sealant can cause the isolation and / or prevent the contact between the plate and receiving profile.

The receiving profile can be arranged separately, in particular thermally separated, from the first and / or second plate. The receptacle or open receiving profile side or the groove or the receiving profile can be substantially flush and / or flush with the butt end face of the security panel. By this flush and / or flush arrangement of the receptacle or the groove or the receiving profile, a simple positioning of another security panel adjacent to the security panel can be made possible. The receiving profile can be configured as a hollow profile, in particular as a U-profile or L-shaped profile. The U-profile has two spaced-apart first profile sections and a second profile section extending substantially perpendicular to the two first profile sections, wherein the second profile section is arranged between the two first profile sections.

The receiving profile may be L-shaped, with two substantially mutually perpendicular profile sections, be configured. A first profile section may be arranged substantially parallel to the flat side of the first plate and / or second plate, and a second profile section may be arranged substantially parallel to the shock end side. The groove, ie the receptacle or open receiving profile side is formed in this case on one side of the first profile section.

The receiving profile, in particular the hollow profile, may have a dimensionally stable and / or resistant material, such as, for example, metal, in particular iron or non-ferrous metal, in particular steel and / or, for example, a plastic and / or a composite material.

The two plates, ie the first plate and the second plate, each have two flat sides. The flat sides of the two plates can have substantially the same dimensions. Therefore, the two plates have the same size with respect to their flat side. However, they may have different dimensions of the front end face or Lagerangsstirnseite, so have a different thickness and / or structure.

The flat sides of the first plate can be dimensioned larger than the flat sides of the second plate. Alternatively, the flat sides of the first plate can be smaller than the flat sides of the second plate. As a result, a step-like impact end face can be formed.

The shock end face can be designed in a step-like manner for a flush mounting, that is to say flush mounting, a fastening means, an insert element and / or a cover. The step-like impact end face can be formed by the fact that the flat sides of the first plate is dimensioned smaller in one direction than the second plate or vice versa. The receiving profile can be attached to the front face of the security panel between the two plates, for example, the receiving profile can be glued using the sealant on the front end face. The cover may cover the insert element and / or the receiving profile, so that they are covered towards the outside of the security panel or the butt joint glazing out and thus protected. The cover may extend substantially over the length of the bumper face.

The receiving profile may extend substantially over the entire length of the shock end face. The security panel may have two receiving profiles, which are each arranged in the edge region of opposite end faces of the security panel between the spaced plates. As a result, a substantially symmetrical construction of the security panel can be made possible, whereby the production of a butt joint glazing can be simplified.

The first panel and / or the second panel may be configured as safety glazing, fire-resistant glazing, insulating glazing and / or glazing. In particular, the fire-resistant glazing can be designed at least as E30 fire-resistant glazing (EN 13501, EN 1364, EN 1363, as of April 2017). It is also possible that heat and / or Sun protection layers, other functional and decorative glasses in the construction of the safety panel or plates can be combined. Screen films, matt films, structured glasses, switchable glasses can also be integrated into the structure of the panels. In the disc structure of the panels or security panel also movable slats, Store, foils can be introduced. The panels may also include composite sheets and composite panels of, for example, PVB, especially EVA and TPU, ionomers, structural interlayer, PMMA, PC.

The two adjacent plates can be spaced apart by a spacer. The spacer can be further in the interior of the security panel, so more shifted to the center of the flat side of the security panel, compared to the receiving profile, be arranged.

The first plate and / or the second plate may have a monolithic and / or multilayer composite pane. The multi-layer disc composite may comprise at least two spaced-apart glasses of float, composite, composite safety or thermally partially or fully tempered single-pane safety glass. Between the spaced-apart glasses, one or more in the event of fire to temperature-responsive, cooling acting, and / or opacifying, foaming, such as from EP 1 194673 known or abusing interlayer / s may be included. It is also possible that only a part of the plate has such a composite pane and / or fire protection interlayer so fire protection Zwischenschicht / s. Security panel in which part of the panel consists of panels which may comprise composite sheets and composite panels of, for example, PVB, in particular EVA and TPU, ionomers, structural interlayers, PMMA, PC.

The first plate and / or the second plate may have an integrated alarm function. Such an alarm function can, for example, as an alarm be configured, in which an Alamischleife, so an electrical conductor loop, is introduced or applied in an toughened glass (toughened safety glass). When the plate is hit, the circuit of the alarm loop is interrupted and the alarm is triggered. When hammering the plate so the resistance of the alarm can be changed, resulting in a signal change the alarm and thus trigger the alarm.

In other words, the security panel or plates or butt joint glazing can combine different security classes, such as attack inhibition, bullet resistance, blast resistance and / or fire protection, with each other. In this case, the structure of the safety panel or the plates or the butt joint glazing can be modified according to the requirements. In particular, an attack inhibition, in particular an intrusion resistance, can be combined with a fire protection function in the butt joint glazing.

The buttstim face in the positioned state of the safety panel in the butt joint glazing run vertically. The impact side runs along the butt joint. The security panels can be arranged horizontally next to each other. In another embodiment, with horizontally extending kick sides, we can place security panels vertically one above the other.

The distance between the two adjacent plates can be filled with a protective gas.

The distance between the two adjacent plates may be filled with a plate structure, in particular a composite glazing and / or a fire-resistant glazing. The set for the production of a break-through resistant, frameless, flush-jointed butt joint glazing with free butt edges, has at least two security panels described above, ie a first security panel and a second security panel, and at least one insert element. The insert element has a first portion and a second portion. The first section is dimensioned such that it can be positioned in the receptacle or open receiving profile side, in particular the groove, ie the receiving profile, of the first of the two security panels. At least a portion of the insert element protrudes in the positioned state at least partially beyond the butt end face of the first safety panel, in particular the second section of the insert element protrudes beyond the butt end face of the first safety panel. The protruding portion of the insert element, in particular the second portion of the insert element, is dimensioned such that it can be positioned in the receptacle, in particular the groove, of the second of the two safety panels. In the positioned state of the insert element in the respective receptacle, in particular in the respective grooves, the two security panels, the two security panels are arranged flush with each other. As a result, it is possible to facilitate the production of a flush and burglary-resistant butt joint glazing with free butt edges.

The insert element may extend substantially over the entire length of the receiving profile. Thus, in the positioned state of the insert element in the respective receptacle or open receiving profile side, in particular in the respective grooves, the two security panels a connection of the two security panels over the entire length of the front end face stabilized or strengthened. The insert element may extend substantially over the entire length of the butt joint end face of the safety panel.

The length of the insert element can exceed the length of the receiving profile, in particular the length of the butt joint end face, and in the positioned state of the Insertion element in the respective receptacle, in particular in the respective grooves, the two safety panel protrude beyond the bearing end face. As a result, the insert element may be attached to an outer tube under certain circumstances. The insert element can, for. B. be formed as a flat profile or I-profile, T-profile and / or cross-section in symmetrical and / or asymmetrical shape. The width of the T-profile, ie the broad side, is formed by two feet and the height of the T-profile is formed by a web. The bridge extends substantially perpendicularly from the feet. The feet may form the first section or the second section of the insert element.

The insert element can be loosely inserted into the receiving profile and / or be inserted or positioned. The loose insertion or insertion allows easy production of resistant butt joint glazing. A choke, wedging or twisting of the insert element in the receptacle can be prevented or reduced. When inserting no frictional and / or positive connection between the receiving profile and insert element. The insert element may comprise a resistant material, in particular metal, in particular steel. It is also possible that the insert element has a plastic, a composite material and / or a ferrous metal or non-ferrous metal. The insert member may also have recesses, these recesses do not affect the resistance and stability of the insert element. In this way, thermal bridges in the butt joint glazing can be reduced. Also, the weight of the butt joint glazing can be reduced. At butt joint glazings without and with fire protection properties of the fire resistance classes E30 to EI 120 with free butt edges (without surrounding frame profiles around the individual safety panels) with two-sided storage (eg above and below) in building interior and exterior areas (eg partitions, window hinges, facades, oblique glazings) Beyond crash and safety thrown out higher security requirements. These requirements are met by the described butt joint glazing.

The first section of the insert element and the second section of the insert element can be designed such that they can be arranged in a stationary manner, in particular fixed relative to one another, and thus can not be mutually displaced. The insert element can not be rotated / rotated relative to the receiving profiles or the recordings in the positioned state with the two sections in the respective receiving profiles. The first and second sections may be integrally connected together. One-piece means that the two sections are inseparable. One-piece can also mean made in one piece. Integral may also mean that the insert element does not consist of several parts or is made of several parts.

The set may comprise a cover element which is adapted to cover a butt joint, in particular the insert element, in the mounted state.

The set can have an additional insert reinforcement, which can be fastened to the insert element. The insert reinforcement can be fastened with a fastening means on the insert element.

The fastening means may be configured as helical, wherein the insert member and the insert reinforcement has a correspondingly adapted to the helical fastening means opening. The opening may have an internal thread, wherein the helical fastening means may have a correspondingly corresponding external thread. The helical fastening means can be configured as a self-locking screw, ie as a self-locking fastening means. The insert element can also be glued to the insert reinforcement.

The insert reinforcement may extend over the entire length of the insert element. The cover element can be fixed to the insert element, the insert reinforcement, the receiving profile, the fastening means and / or the front end face. By such a fixation, the butt joint can be protected.

The set may have a foamable or foaming in case of fire band, which can be arranged in the butt joint of the butt joint glazing, between the first and the second security panel. The foamable band may extend substantially over the entire length of the shock end face, from one bearing face to the other bearing face, of the safety panel. The robust, flush-jointed butt joint glazing with free butt edges has a set as described and an outer frame. The butt joint glazing is a flush glass facade or glazing. The two security panels are arranged adjacent to each other along their front face. The two safety panels are arranged flush with each other. Each of the two security panels has two opposing Lagerimgvorirnseiten. The bearing end faces are each stored or held in the outer frame. That is to say an edge region of the security panel), in particular the bearing end face, projects into the outer frame and is supported or held in this edge region. Such bearings of glazing in the frame are known in the art and serve the attachment / fixation of glass in the frame. These bearings can, for example, by so-called blockages are made possible. Between the two adjacent safety panels a butt joint is formed, this butt joint responds to a cavity between the adjacent safety panel. Between the first security panel and the second security panel, the insert element is arranged over the butt joint in the receptacle or open receiving profile side, in particular the groove, the first security panel and the receptacle, in particular the groove, of the second security panel. This allows stabilization of the adjacent butt edges of the butt joint glazing. The butt joint may be sealed with a seal or sealant. This allows protection against insights and / or external influences, such as weather, wind and / or humidity. The butt edges run along the butt end face and therefore extend substantially at right angles to the outer frame. The butt edges of the butt joint glazing are not covered by a frame, ie frame-free or frameless. As a result, a visually attractive butt joint glazing is provided, which has resistant, in particular burglar-resistant properties.

The butt joint glazing may correspond to burglary - resistant butt joint glazing of resistance classes RC1 - RC6 (according to EN 1627: 201 1).

As already described, the insert element may be loosely inserted or inserted in the receiving profile. The connection is therefore not frictional and / or positive. Rather, the butt joint glazing forms a loose, two-sided composite, which can be reinforced by the insert element.

The seal and / or a sealant that can secure the receiving profile with a sealant in the edge region of the safety panel may have a opaque material. In this way, the insert element remains hidden in the butt joint and is not visible to the skilled perpetrator (burglar). The security panel may have a screen print in the edge area. As a result, the area near the butt joint can be protected and the insert element concealed opaque. The butt joint glazing may also have further security panels with receiving profiles in the two opposite end faces and further insert elements. The additional security panel can be arranged flush between the first security panel and the second security panel and connected to the further insert element with the first security panel and the second security panel without a frame and with free edge bumps.

The insert element can be designed such that it does not protrude from the flush-jointed butt joint glazing in the positioned state. That is, it does not protrude from a plane defined by the butt joint glazing. This "plane" is defined by the flat sides of the flush-mounted safety panel, in other words: In the positioned state, the insert element protrudes from the flat side or the plane of the flat side of the safety panel, which of course refers to the outer flat sides of the safety panel can be used in a butt joint glazing as described and extend along the impact side of the safety panel, in particular the insert element can be configured as a T profile and / or cross profile in symmetrical and / or asymmetrical form The cover element can be designed such that it extends substantially over the length of the joint gap.The cover element can be fastened in the region of the impact side of the adjacent safety panel, for example, the cover element can be glued into the joint joint Ebekante or glue joint can essentially over the entire length of the butt joint extend. This then the butt joint and / or the insert element are protected from external violence and the strength of the butt joint glazing can be maintained. With the help of the cover, the insert element can be made accessible after extensive removal of the cover. This makes it possible to remove a damaged safety panel from the butt joint glazing and insert a new safety panel into the butt joint glazing without having to disassemble the entire butt joint glazing. Such a simple replacement of security panel may be advantageous to ensure a visually pleasing flush-fitted butt joint glazing in the long term.

The cover element can be configured in such a way that, when installed, it can be arranged substantially flush with the flat sides of the adjacent safety panel in the butt joint glazing. The cover member may comprise a opaque material. The cover can be arranged in particular the butt joint between two security panels with step-like Stossstirnseiten.

The intumescent or foamable in case of fire band can be arranged in the butt joint between the first and the second security panel. As a result, the butt joint can be sealed in case of fire and a passage of vapors, gases and / or direct heat radiation can be prevented after foaming. The foamable band may extend substantially the length of the butt joint.

The insert reinforcement can be attached to the insert element. As a result, the resistance of the butt joint glazing can be further improved. In particular, the insert reinforcement can be fastened to the insert element with the helical fastening means. It is possible that the cover element can be fastened to the fastening means, the insert reinforcement and / or the insert element. Can the cover be designed clickable or clickable. As a result, a non-destructive removal of the cover, for example with special tools, are made possible.

As previously described, the butt joint may extend vertically between the first and second security panels. The insert element and / or the insert reinforcement can be fastened, in particular glued, in the receptacle or open receptacle profile side, in particular in the groove, of the receptacle profile.

A process for making the tough, flush butt joint glazing may include the following steps:

- Providing a set as described;

- spreading an outer frame;

- Fixing the outer frame in a building opening;

- Storage of at least one storage side of the first security panel in the outer frame;

- Positioning or insertion of the insert element in or in the receiving profile of the first security panel;

Positioning of the receiving profile of the second security panel adjacent to the first security panel, wherein the second portion of the insert element is positioned in the receiving profile of the second security panel.

When inserting the insert element into the receptacle of the first security panel, the first section is positioned in the receiving profile of the first security panel and the second section protrudes beyond the over the impact side of the first security panel. When positioning the second security panel adjacent to the first security panel, the second section is positioned or inserted in the receiving profile of the second security panel. The positioning can be made possible for example by a lateral insertion of the second security panel. The butt end faces of the two safety panels are pushed one on top of the other. One of the safety panels can already be stored in the outer frame.

The method may comprise a further step: sealing the butt joint between the first and the second security panel, in particular the edge region of the butt joint, with a seal. The seal may be opaque, as described above.

Before the sealing, a frothable band can be arranged between the first and the second safety panel. As a result, the resistance of the butt joint glazing can be improved.

After positioning the second security panel adjacent to the first security panel, the second security panel can be stored in the outer frame. The storage can also be done before positioning, but the storage in this case should allow a subsequent positioning of the second section in the receiving profile of the second security panel.

Further preferred embodiments emerge from the dependent claims.

Basically, the same or analogous parts are provided with the same reference numerals in the figures.

Figures 1 and 2 each show a cross section of a security panel 1 for the production of a resilient, flush-fitted butt joint glazing 2. The security panel 1 has two plates 44, namely a first plate 44a and a second plate 44b. The two plates 44 and the security panel 1 are substantially transparent.
