SHOOTING ARMEN DE GLAZING

description

The invention relates to bullet-resistant glazing. In particular, the invention relates to transparent, splinter-free and bullet-resistant glazing and its use. It is known to design wall constructions, for example building facades, in the case of objects at risk from fire, to be bullet-resistant. If such facade or wall constructions are to be made transparent, bullet-resistant glass elements are arranged. In view of the high demands placed on thermal insulation, bullet-resistant insulating glass elements are generally used.

For example, such a bullet-resistant insulating glass element is known from the document DE 2 901 951 A1. In this case, the insulating glass plane is formed by two individual panes spaced apart from one another by a spacer. The resulting air gap ensures the desired improved thermal insulation.

The bullet-resistant glass level is formed by further individual panes arranged on the individual panes and bonded to one another. This results in so-called laminated glass packages, which are made up of several individual panes arranged one behind the other, which are connected to one another on their mutually contacting surfaces by foils or cast resin. However, the dimensions of the bullet-resistant insulating glass elements are limited for manufacturing, transport technology and architectural reasons. For façade or wall constructions, therefore, a large number of individual bullet-resistant insulating glass elements are required, which must be arranged at a distance from one another in order to be able to arrange the elements that ultimately form the frame, in order then to enable the edges to be held in place by individual insulating glass elements .

However, this approach has several disadvantages. If, for example, an oblique bombardment occurs in the edge region of the bullet-resistant insulating glass elements, in which the weft path in the bullet-resistant insulating glass element, i.e. the storeys can emerge in the edge area of the insulating glass elements to its main level, which runs obliquely. After that, the storeys only have to penetrate the designated elements of the facade construction in order to reach the area to be protected.

The elements of the facade holding the bullet-proof insulating glass elements are generally composite profile arrangements, in particular in the form of hollow chamber profiles made of aluminum, which do not have a sufficient bullet-proof effect. Since the bullets only have to penetrate a part of the individual panes of the laminated glass package during the oblique bombardment, this poses a danger to the area to be protected. The bombardment of the bullet-resistant insulating glass elements can be extremely strong in individual cases.

In order to avoid this disadvantage, it is known to provide steel inserts on the elements of the facade in the area between adjacent insulating glass elements. In individual cases, several such steel inserts have to be provided, which can be arranged, for example, in cavities of corresponding hollow chamber profiles.

The arrangement of such steel inserts is extremely labor-intensive, however, since a number of additional work steps are required in the production of corresponding facade constructions. For example, the steel inserts have to be deflected according to the length of the elements of the facade construction to be protected and inserted in places that are difficult to access and be attached. Sometimes additional steel corner pieces in the area of corner connections have to be taken into account, which should also protect the facade construction in the corner areas against shelling.

Another problem with such steel inserts is the interruption of the desired poor heat transfer in the corresponding areas of the facade. It may therefore be necessary to arrange additional insulation inserts, which in turn cause additional costs due to manufacture and, above all, assembly.

Instead of using steel inserts, it would - at least theoretically - be conceivable to enlarge the dimensions of the bullet-proof insulating glass elements. As already indicated, however, the dimensions are limited, in particular for manufacturing reasons. In particular, for technical reasons, bullet-proof or bullet-resistant glazing with dimensions greater than 7 m (length) x 2 m (width) cannot be implemented at present, since this is the critical size of the polycarbonate that is usually applied to bulletproof glass on a surface opposite the direction of the bullet. Plate or a shatter protection film is. Larger formats cannot be realized in particular because the static requirements can then no longer be met. This is due in particular to the fact that laminate films for polycarbonate can no longer carry the load from a size of approximately 14 m ² .

In addition, the proportion of polycarbonate in the bullet-resistant or bullet-resistant glazing would have a positive effect on the bullet resistance, but there are negative consequences for the fire behavior if the plastic or polycarbonate component reaches a certain mass.

On the basis of this problem, the invention is based on the object of specifying bullet-resistant glazing with which dimensions can also be realized which are significantly greater than the dimensions of approximately 7 mx 2 m which are currently feasible, with a splinter exit at the same time Bombardment of the glazing is to be effectively prevented, and the bullet-resistant glazing also fulfills the conditions for the classification BR1-NS to BR7-NS specified in standard EN 1063 (status of the standard: filing date). According to the invention, this object is achieved by the subject matter of independent claim 1, with advantageous developments of the bullet-proof glazing mentioned in independent claim 1 being specified in the subclaims.

Accordingly, the present invention relates in particular to bullet-resistant glazing with a ballistic block composed of at least two transparent panes which are connected to one another via an intermediate layer. In addition to the ballistic block, the bullet-resistant glazing has at least one further transparent pane, which is arranged parallel to and spaced from the panes of the ballistic block and is connected to the ballistic block via a circumferential spacer such that A cavity is formed between the ballistic block and the at least one further disk.

According to the invention, it is provided in particular that the bullet-proof glazing and in particular the ballistic block of the bullet-proof glazing are designed without an energy-absorbing layer or film made of polycarbonate.

According to embodiments of the bullet-proof glazing, it is further provided that the intermediate layer between the at least two transparent panes of the ballistic block is formed from a material which is highly resistant to polycarbonate. Of course, this aspect is not to be regarded as restrictive.

In particular, in the case of the bullet-proof glazing, it is provided that the intermediate layer, via which the at least two transparent panes of the ballistic block are connected to one another, comprises a transparent and in particular polycarbonate-free and / or polymethyl methacrylate-free intermediate layer, which is compared to a polycarbonate material connects the panes with high strength.

The advantages that can be achieved with the solution according to the invention are obvious. The fact that the bullet-proof glazing has a ballistic block and at least one further transparent pane which is spaced from is arranged on the ballistic block, there is bullet-proof double-skin insulating glazing, which due to the air gap between the ballistic block on the one hand and the at least one further transparent one

On the other hand, the pane provides good thermal insulation.

On the other hand, the selected multi-layer glazing proves to be very effective in terms of its bulletproof or bulletproof properties. The ballistic block arranged on the shelling side essentially prevents a bullet, while the at least one further disc arranged at a distance from the ballistic block on the side facing away from the shelling side has the task that occurs on the back of the ballistic block Intercept shelling, if necessary, to replace splinters.

Because the ballistic block of the glazing according to the invention has a large number of transparent panes which are connected to one another by means of an intermediate layer, the ballistic block itself taking on the function of energy absorption, it is possible to use any energy-absorbing foils or plates in particular to dispense with a surface of the disks of the ballistic block that is in particular opposite a potential direction of fire.

In addition, this approach enables the disks of the ballistic block to be connected with the aid of an intermediate layer, so that the ballistic block simultaneously forms a resilient, load-bearing structure, in particular also in sizes larger than 15 m ² . The intermediate layer is, in particular, transparent and, above all, is formed from a polycarbonate-free and / or polymethyl methacrylate-free material.

With this measure, the production size limited in the case of conventional splinter protection films known from the prior art is eliminated. In this respect, sizes for the bullet-resistant glazing in the range of, for example, 20 mx 3.5 m (or larger) are also conceivable. In particular, an overall bullet-resistant effect can be achieved without splintering without the bullet-proof glazing and in particular the ballistic block of the bullet-proof glazing having an energy-absorbing layer or film made of polycarbonate. In this context, it is particularly preferably provided that the intermediate layer or intermediate layers of the ballistic block is at least partially or partially formed from an ionoplast polymer or a material with similar material properties, such as, for example, high-strength polyvinyl butyral (PVB).

In this context, a two-component and in particular crystal-clear silicone is particularly suitable as the material for the intermediate layer or intermediate layers of the ballistic block. Such a two-component silicone material is particularly advantageous with regard to fire behavior, since it is difficult or difficult to ignite. According to embodiments of this aspect, a reactive and preferably crystal-clear silicone material is used in particular, which reacts from a critical temperature that can be determined in advance. Such a silicone material can then be cooled, i.e. in a state below the critical curing temperature, poured into a space between two panes of the ballistic block or introduced in some other way.

Compared to conventional PVB foils or PVB sheets or conventional polycarbonate sheets, which are applied as an energy-absorbing structure on an outer surface of the panes, intermediate layers made of high-strength polyvinyl butyral or a two-component silicone material or an ionoplastic intermediate layer are essential tougher and stiffer, so that the ballistic block does not become unstable even with a larger weight (ie with larger dimensions), but remains statically self-supporting overall.

In addition, it has been shown that a bullet-resistant laminated glass, in which a polycarbonate film is used as a ductile, energy-absorbing plastic outer layer, can form cracks in the layer due to the properties of the polycarbonate layer as a function of temperature have a negative impact on the overall appearance and the safety of the laminated safety glass.

By using an intermediate layer, for example made of ionoplast, in the ballistic block of the glazing according to the invention, instead of a polycarbonate outer plate, even at high temperatures Fluctuations in outdoor use do not cause any cracks in the ionoplastic interlayer in the long term, since it is much stiffer and stronger than polycarbonate.

In particular, the use of a polycarbonate-free ballistic block, and in particular the use of an ionoplast intermediate layer as an energy-absorbing plastic intermediate layer, allow the dimensions of the glazing to be realized at least 15 m ² and preferably at least 20 m ² . This is due in particular to the fact that the high-strength intermediate layer on the one hand can reduce the amount of plastic material per unit area, which has a positive effect on the fire behavior of the glazing, and on the other hand that the ballistic block is statically self-supporting even with an area of over 15 m ² .

The bullet-proofing effect is assessed after five bullet classes. In the currently highest fire class and resistance class BR7, for example, the attempt to fire the NATO rifle G3 is carried out with a 7.62 x 51 full-shell / hard-core ammunition. In this fire class, the highest demands are placed on the bullet resistance.

According to embodiments of the present invention, the ballistic block has a thickness, as seen in the direction of fire, which resists shooting with a 7.62 × 51 mm solid jacket / hard core cartridge in accordance with DIN EN 1063, the thickness of the ballistic block being formed in particular is determined by a corresponding number of transparent panes, each of which is connected to one another by an intermediate layer, and / or by corresponding thicknesses of the transparent panes of the ballistic block.

In order to further optimize the thermal insulation of the bullet-resistant glazing, it can be provided according to embodiments that the cavity between the ballistic block on the one hand and the at least one further transparent pane on the other hand is hermetically sealed and with a gas with a low heat transfer coefficient, such as argon and / or krypton.

In contrast to the ballistic block constructed as a composite, there is at least one further one with regard to the ballistic block spaced apart from the ballistic block It is not necessary to provide a transparent pane, provided that a laminated glass is used again with a high-strength intermediate layer. Rather, a laminated glass pane is preferably used as at least one further pane, which consists of several individual panes which are connected to one another via an elastic, tear-resistant polymer film. For example, polyvinyl butyral (PVB) is used as the polymer film.

The PVB layer has a thickness of at least 0.76 mm, preferably at least 0.90 mm and more preferably at least 1.52 mm. Polyvinyl butyral (PVB) is characterized by its high tear strength and also has a high splinter-binding effect due to its high adhesive strength.

Between the ballistic block, on the one hand, and the at least one further transparent pane, on the other hand, an intermediate space is provided, in which splinters that may occur when fired at are bombarded. The space also serves to allow the glazing to bend to a limited extent. A distance between the ballistic block and the at least one further disk of 8 mm to 24 mm, preferably of 12 mm to 16 mm, has proven to be advantageous.

Values between 13 mm and 60 mm have proven advantageous for the thickness of the ballistic block and values between 9 mm and 21 mm have proven advantageous for the thickness of the at least one further disk. Here, the highest possible protection and the weight of the entire glazing reflect a role.

In embodiments of the double-skin glazing according to the invention, this has a total thickness of approximately 60 mm, the ballistic block arranged on the shelling side having a total thickness of 30 to 40 mm and a total intermediate layer thickness of 3 to 5 mm.

The air gap between the ballistic block on the one hand and the at least one further transparent pane is preferably 12 to 16 mm, the at least one further pane, in particular laminated glass pane, facing away from the shelling side having a thickness of 9 to 21 mm. This at least one further pane can, for example, consist of a thin silicate glass pane facing the air gap and a thermally toughened silicate glass pane directed towards the outside h. This laminated glass pane is constructed in such a way that the outer, thermally toughened glass pane with high flexural strength can withstand the bending stresses caused by the deflection of the destroyed ballistic block and the bending stresses acting on it through the outgoing splinters, without breaking. It is protected against damage to its surface by the splinters that occur and / or by contact with the bulged front panes of the ballistic block by means of the thin normal glass pane that is directed towards the air gap, so that the surface of this prestressed glass pane remains undamaged and thus the full high flexural strength the thermally toughened glass pane comes into play.

According to a further aspect of the present invention, the thickness and / or the material of the at least one intermediate layer of the ballistic block and / or the at least one further transparent pane designed as a laminated glass is selected such that the calorific value of the material is less than 55 MJ / kg, and preferably less than 50 MJ / kg, and more preferably less than 45 MJ / kg.

In this way, the fire protection classification of the glazing can be improved. It is advisable if the mass distribution of the intermediate layer of the ballistic block and / or of the at least one further transparent pane designed as laminated glass is between 0.02 g / m ² and 0.10 g / m ² , preferably between 0 , 05 g / m ² and 0.08 g / m ² and in particular 0.07 g / m ² .

Exemplary embodiments of the bullet-proof glazing according to the invention are described in more detail below with reference to the accompanying drawings.

FIG. 3 schematically and in a cross-sectional view a further embodiment of the bulletproof glazing according to the invention.

A bulletproof glazing 100 without splinter exit according to the classes BR1-NS to BR7-NS according to the standard EN 1063 is based on the current state of the art primarily on the approach to retain the outgoing splinters through tough layers on the inside of the glazing 100 . These layers usually consist of either polycarbonate or a tear-proof, clear shatterproof film.

Due to their function, these layers, which are always on the innermost side, have the disadvantage that they do not have the scratch resistance that is comparable to glass surfaces. For this reason, placing the splinterguard in the space between the panes currently does not allow the possibility of applying suitable sun protection coatings, which is very often necessary for the glazing 100 to have the required physical building values.

In addition, the currently available anti-shatter films or polycarbonate sheets are limited in their production size. From certain sizes of insulating glass or corresponding static requirements, the use of TPU composite films required for the lamination of polycarbonate on glass is no longer sufficient for load transfer. The fire protection classification of this glazing 100 is also very unfavorable due to the large combustible mass of polycarbonate.

These and other disadvantages are overcome by the glazing 100 according to the invention, in which it is provided in particular that the glass and projectile splinter exits of the outside unclassified bulletproof glass pane which occur during the bombardment are caught in the form of a ballistic block in the interspace between the bullet-proof glazing 100 . The space between the panes is used as a buffer for the pressure wave and the splitter ports. In the end, the entire glazing 100 designed as an insulating glass unit achieves the necessary classification. Specifically, in the case of FIG. 1 schematically illustrated embodiment of the glazing 100 according to the invention embodied this with an external bulletproof glass pane as a ballistic block 10. For this purpose, the ballistic block 10 has at least two and - as in FIG. 1 indicated - for example, four transparent panes 11, 12, 13, 14, which are each connected to one another via an intermediate layer 19.

Parallel to the panes 11, 12, 13, 14 of the ballistic block 10 and spaced therefrom by a circumferential spacer 21, a laminated glass pane 15 with a total of two (further) transparent panes 15, 16 is provided, which are placed over the spacer 21 is connected to the ballistic block 10 such that a cavity 20 is formed between the ballistic block 10 on the one hand and the laminated glass pane 15 on the other hand.

Accordingly, the bullet-resistant glazing 100 consists of the ballistic block 10 facing the bullet side, which is designed as a laminated glass pane overall, and the at least one further transparent pane 15, 16 facing away from the bullet side, which is also designed here as a laminated glass pane 15.

This at least one further transparent pane 15, 16, which is designed as a laminated glass pane 15, is combined with the ballistic block 10 and the interposition of an air gap 20 to form a double-shell insulating glazing, specifically by the ballistic block 10 and the at least one further transparent pane Disc 15, 16 are connected to the spacer frame or spacer 21 via adhesive layers. The through the edge areas of the ballistic block 10 and the at least one further transparent

Washer 15, 16 and the spacer 21 / spacer formed fillet are made with a sealing compound.

The ballistic block 10, designed as a laminated glass pane, has in the case of FIG. 1 shown exemplary embodiment a total of four glass panes 11, 12, 13, 14, each of which is, for example, silicate glass panes, which are connected to one another with the aid of intermediate layers 19 made of an ionoplastic polymer. The glass panes 11, 12, 13, 14 of the ballistic block 10 designed as a laminated glass pane can each have the same thickness; However, it would also be conceivable to make the outer glass panes 11, 14 of the ballistic block 10 in the form of a laminated glass pane significantly thinner than the central glass panes 12, 13. In these embodiments, the thicknesses of the glass panes 11, 12, 13, 14 of the Ballistic block 10 designed as a laminated glass pane, for example at approximately 8 to 15 mm.

The air gap 20 between the ballistic block 10 and the at least one further laminated glass pane 15 is preferably at least about 12 mm.

The at least one further laminated glass pane 15 comprises the glass pane facing the air intermediate space 20, which can be designed, for example, as a silicate glass pane with a thickness of approximately 3 mm, for example.

This glass pane 17 facing the air gap is connected to an outer glass pane 16 made of thermally toughened silicate glass via an intermediate layer 22, in particular a polyvinyl butyral intermediate layer with a thickness of, for example, 1.5 mm. This outer glass pane 16 of the at least one further laminated glass pane 15 can have the same thickness as the inner glass pane 16.

However, it is also conceivable to choose a greater thickness for the outer glass pane 16, for example a thickness of 6 mm, so that a bending strength of at least 500 kg / cm ^{2 can be} achieved.

The glazing 100 according to the invention has a bullet-resistant effect in accordance with the resistance class BR37-NS, with no splinter exit on the side facing away from the bullet.

A classified bulletproof outer pane is not required to manufacture the bullet-resistant glazing 100, which significantly reduces the overall structure of the glass thickness and thus the weight and cost of the entire glazing 100. This new application also removes the previous size limitation, for example due to the availability of polycarbonate sheets for the bulletproof glass. In theory, sizes of at least 20 mx 3.5 m are now possible.

In addition, cleaning of the glass surfaces is possible as is the case with all glass surfaces. In particular, there is no need to consider scratching polycarbonate or the shatterproof films.

Furthermore, the application of sun protection and heat protection coatings to any surface in the pane 20 of the glazing 100 is possible without any problems.

By using high-strength, permanently load-transmitting composite films such as B. ionoplasts or high-strength PVB films in the external ballistic block, these glasses can be subjected to additional static loads. The main advantage is that the ballistic block also represents the statically resilient outer pane of the insulating glass structure. This is particularly relevant when using appropriately high loads (e.g. hurricane loads) or simply oversized insulating glass. For the inner composite pane, the only task left is to create an insulated space between the panes and to capture the splitter outlets.

All this is not possible if polycarbonate plates or splinter protection films are used to protect against splinters. Because in a lamination process with corresponding composite films, such as TPU film (thermoplastic polyurethane), high-strength films cannot be connected at the same time in the same package. These high-strength films, e.g. B. ionoplast films, need their own program with z. B. higher temperatures, the TPU film would overheat and become unusable.

Ultimately, there is no deterioration in the fire protection classification through the use of standard VSG composite units.

FIG. 2 and FIG. 3 each show schematically and in a cross-sectional view further embodiments of the bulletproof glazing 100 according to the invention. 2 is the glazing 100 according to the invention with an external one Tempered glass pane designed as a ballistic block 10, the ballistic block 10 here having a total of four transparent panes 11, 12, 13 and 14, which are each connected to one another by an intermediate layer 19. Parallel to the panes 11, 12, 13 and 14 of the ballistic block 10 and spaced apart therefrom by a circumferential spacer 21, a laminated glass pane 15 is provided with a total of two (further) transparent panes 15, 16 which are spaced about the spacer 21 are connected to the ballistic block 10 such that a cavity 20 is formed between the ballistic block 10 on the one hand and the laminated glass pane 15 on the other hand.

In the case of FIG. 2 schematically shown glazing 100 is in particular provided that it is convexly curved towards the outside. In contrast, in the case of FIG. 3 schematically shown embodiment provided that the glazing 100 shown there is concave with respect to the outside. Otherwise corresponds to that in FIG. 3 shown embodiment of the glazing 100 of the invention shown in FIG. 2 embodiment shown.

The curved design of the glazing can be realized due to the special structure of the glazing.
