DETAILED DESCRIPTION OF THE INVENTION

[0093] Identical or analogous parts are basically provided with the same reference signs in the figures.

[0094] FIGS. 1 and 2 each show a cross section of a safety panel 1 for producing resistant, surface-flush butt joint glazing 2. The safety panel 1 has two plates 44, namely a first plate 44a and a second plate 44b. The two plates 44 and the safety panel 1 are substantially transparent. The two plates 44 are spaced apart from each other by a distance D with the aid of a spacer 32. The intermediate space between the two plates 44 is filled with an inert gas. The first plate 44a is configured as single-pane safety glazing. The second plate 44b is configured as composite glazing and has fire-protection glazing and a pane composite. The fire-protection glazing has three panes, between which a fire-protection interlayer reacting, in particular becoming cloudy, in the event of a fire is arranged. However, the fire-protection glazing may also have only two panes or at least two panes. The fire-protection glazing be E30 or E60 glazing. The fire-protection interlayer is surrounded in an encircling manner by a sealing compound. The pane composite is formed by adhesively bonding a pane of fire-protection glazing to a further pane. The adhesive bonding can be made possible, for example, by a film. A receiving profile 11 is arranged between the first plate 44a and the second plate 44b and is fastened between the two plates 44 with a sealing compound 12. The receiving profile can also be called a reinforcing profile. The receiving profile is arranged in a border region of the abutting end side of the safety panel and forms an open groove, i.e. a receptacle, which is also called open receiving profile side, toward the abutting end side. The abutting end side with the groove may also be called connection side or abutting side, and a further safety panel can be connected to the safety panel in a surface-flush manner without an additional frame via the connection side or abutting side.

[0095] The safety panel and/or the plate are/is a surface element, which includes two substantially parallel large outer surfaces, which are also called flat sides. In the present text, the encircling surface regions of the safety panel or of the plate between the flat sides are called end sides, and sometimes the terms edge or narrow side of a safety panel or of a plate are also used for this purpose. The end side here has a smaller surface than the flat sides, and an extent of the end side perpendicular to the large surfaces corresponds to the thickness of the safety panel or of the plate. A border region of the safety panel and/or of the plate, which border region can be arranged in a frame, may also be referred to as a border flange. The border region is therefore a region of the safety panel and/or of the plate, which is arranged in the vicinity of the end side. A rectangular safety panel or a rectangular plate includes four end sides; two opposite end sides can be referred to here as mounting end sides, and the other two end sides can be referred to as an abutting end side.

[0096] In the case of the safety panel 1 shown in FIG. 1, the two plates, i.e. the first plate and the second plate, each include two flat sides. The flat sides of the two plates substantially include identical dimensioning. The two plates therefore have the same size with respect to the flat side.

[0097] The abutting end side 15 shown in FIG. 2 is of step-like design, and the flat sides of the two plates 44 are dimensioned differently. That is to say, the first plate 44a is smaller than the second plate 44b.

[0098] As already described, the two plates 44 have a different construction and a different extent of the abutting end side and mounting end side, i.e. a different thickness.

[0099] FIG. 3 shows a cross section of resistant butt joint glazing 2 with free abutting edges. The butt joint glazing 2 includes two safety panels 1 which are arranged in a surface-flush manner with respect to each other, as shown in FIG. 1. The two safety panels are arranged adjacent to each other along their abutting end side. Each of the two safety panels in each case includes two opposite mounting end sides. The mounting end sides are each mounted or held in an outer frame (not shown). A butt joint 21 is formed between the two adjacent safety panels 1; the butt joint 21 corresponds to a cavity between the adjacent safety panels 1. Between the first safety panel and the second safety panel, an insert element 10 is arranged along the butt joint 21 in the groove of the first safety panel and the groove of the second safety panel. The butt joint is sealed with a seal 30. This permits stabilization of the adjacent abutting edges of the butt joint glazing and protection against view and/or external effects, such as weather, wind and/or moisture. The receiving profile 11 is in the form of a flat profile. An outer frame 22 is not arranged in the region of the butt joint 21. A band 31, which is foamable or foams in the event of a fire, is arranged in the butt joint 21 and, in the event of a fire, permits sealing of the butt joint 21 against the passage of vapors and/or gases.

[0100] FIG. 4 shows a cross section of alternative, resistant butt joint glazing 2 with free abutting edges. The construction of the butt joint glazing 2 substantially corresponds to the construction of the butt joint glazing 2, as shown in FIG. 3. The insert element 10 is in the form of a T profile. The width of the T profile, i.e., the wide side, is formed by two feet, and the height of the T profile is formed by a web. The web extends substantially at a right angle from the feet. The wide side of the insert element 10 is arranged in the respective receiving profiles 11 of the adjacent safety panels 1. The web of the insert element 10 is arranged in the butt joint 21 of the butt joint glazing 2. The web is arranged between the second plate 44b of the adjacent safety panels 1.

[0101] FIG. 5 shows a cross section of further, alternative, resistant butt joint glazing 2 with free abutting edges. The second plate 44b is configured similarly here to the second plate 44b shown in FIG. 1 or 2. The first plate 44a is configured as composite glass 46 and has three panes which are connected or adhesively bonded to one another by a composite film. However, the first plate 44a can also be configured as single-pane safety glass. The same applies to the second plate 44b. A combination with a fire-protection function, as shown in FIG. 5, such as, for example, the second plate 44b, can likewise be realized. The second plate 44b includes fire-protection intermediate layers 45 or a fire-protection interlayer between adjacent panes. Furthermore, one of the panes is configured as composite glass 46. The butt joint glazing 2 includes an insert element 10 in the shape of a T profile. The wide side of the insert element 10 is arranged in the respective receiving profiles 11 of the adjacent safety panels 1. The web of the insert element 10 is arranged in the butt joint 21 of the butt joint glazing 2. The web is arranged between the first plate 44a of the adjacent safety panels 1.

[0102] FIG. 6 shows a cross section of further, alternative, resistant butt joint glazing 2 with free abutting edges. The two safety panels 1 are of step-like design, similarly as shown in FIG. 2. The receiving profile 11 is configured as an L profile and has a receiving profile side, i.e. receptacle, which is open to the abutting end side 15. The insert element 10 is configured as a T profile, similarly as shown in FIG. 4 and FIG. 5. Additionally, the butt joint glazing 2 includes a covering element 17 which is configured to cover the butt joint 21 and the insert element 10 opaquely. The butt joint glazing 2 includes an insert reinforcement 18 which is fixed to the insert element 10 with a fastening means 19. The fastening means 19 is in the form of a screw-shaped, self-securing fastening means 19. After the screw connection of insert reinforcement 18 and insert element 10, the screw head has been sealed with a seal. The insert element 10 and the insert reinforcement 18 can therefore be connected exclusively by the forceful destruction of the fastening means 19. The resistance of the butt joint glazing 2 can thereby be improved. The covering element 17 and the insert element 10 are adhesively bonded into the butt joint 21. Before the insert element 10 is positioned in the receiving profile 11, the butt joint 21 is freely accessible, as a result of which the installation or construction of the butt joint glazing 2 and the interchanging of individual safety panels 1 from existing butt joint glazing 2 can be facilitated.

[0103] FIG. 7 shows butt joint glazing 2 with free abutting edges. The butt joint glazing 2 includes at least three safety panels 1 and an outer frame 22. The butt joint glazing 2 is a surface-flush glass faade or glazing. The safety panels 1 are arranged adjacent to one another along their abutting end side. The safety panels 1 are arranged in a surface-flush manner with respect to one another. Each of the safety panels 1 in each case includes two opposite mounting end sides 16. The mounting end sides 16 are each mounted or held in the outer frame 22. A border region of the safety panel 1 enters the outer frame 22 and is mounted or held in the border region. A butt joint 21 is in each case formed between the adjacent safety panels 1; the butt joint 21 corresponds to a cavity between the adjacent safety panels 1. Between the safety panels 1, the insert element 10 is arranged beyond the butt joint 21 in the groove of the adjacent safety panels 1. The butt joint 21 is sealed with a seal. This enables stabilization of the adjacent abutting edges of the butt joint glazing 2 and protection against view and/or external effects, such as weather, wind and/or moisture. The abutting edges run along the abutting end side 15 and therefore extend substantially at a right angle to the outer frame 22. The abutting edges of the butt joint glazing 2 are not covered by a frame, i.e., are frame-free or frameless. Visually attractive butt joint glazing, which includes, for example, burglar-resistant properties is thereby provided.

[0104] The safety panels 1 do not have to include any purely rectangular dimensioning of the flat sides. On the contrary, one or more safety panels 1 is can include a substantially rectangular shape in which, for example, the mounting end side 16, which is held in the outer frame 22, of the safety panel 1 is rounded, and includes a triangular flattening of the substantially rectangular shape and/or a recess in the corner region of the substantially rectangular shape of the safety panel 1, as illustrated by dashed lines in FIG. 6.
