Definitions
- the invention relates to a bullet-resistant glass louvre window construction for building installations, in particular for vertical facades with a closed all-glass look on the outside of the building.
- Louvre windows usually have a rectangular window frame in which several lamellas are arranged parallel next to or one above the other. When the louvre window is closed, the louvres form a window surface which is plane-parallel to the window frame and which closes the opening of the window frame.
- the slats are mounted on axes of rotation fixed in the window frame and, in order to open the slat window, can be swiveled synchronously into an open state by means of a drive mechanism acting simultaneously on all slats.
- Louvre windows are already known from the prior art in which an all-glass look is achieved within the window frame.
- the lamellas consist of an inner and an outer glass pane, which are glued to one another at their edges using spacers, so that an airtight cavity is formed between the glass panes.
- the opposing side surfaces of adjacent slats are bevelled in opposite directions, so that a gap that remains between the adjacent slats in the closed state is as small as possible.
- the outer glass and the spacers are shifted relative to the inner glass and parallel to the axis of rotation, so that a stepped overlap is formed in the area of the spacers between the adjacent lamellae, in which the adjacent lamellae can rest against one another.
- the utility model DE 202 04 044 U1 discloses a louvre window in which the louvres each consist of an insulating glass pane which is held in a louvre frame made of metal profile.
- the insulating glass pane consists of an inner and an outer glass pane which are glued to one another via a spacer that runs around the edge of the inner glass pane.
- the The insulating glass pane is surrounded on all sides by the lamella frame, it being possible for the lamella frame to be glued in between the two glass panes in the area of the spacer.
- the slat frame is covered by the outer panes of the slats and is not visible from the outside of the building.
- Axle stubs are attached to the slat frame, on which the slats are rotatably received in the window frame.
- elastic sealing means are used in the slat frame.
- the window surfaces of the closed slats are framed by the window frame, so that the window frames mounted on a facade always remain visible. Due to the disclosed type of rotatable mounting, in which part of the lamella is pivoted to the inside and part of the lamella to the outside of the window frame, it is in principle not possible to cover the window frame with a facade element mounted on the lamella frame. A facade with an all-glass look, in which the window frame remains hidden behind the facade elements, cannot be achieved in this way. Bullet resistance measures are also not provided.
- a louvre window is known in which the louvres for opening the louvre window perform a combined opening and pivoting movement in the direction of the outside of the window frame.
- the slats therefore always remain outside the window frame and no longer plunge into the window frame towards the inside of the window.
- the opening and pivoting movement is achieved by a multi-articulated movement mechanism via which the slats are connected to the window frame on both sides. Due to the combined opening and pivoting movement, it is in principle possible to mount facade elements on the louvre frame in such a way that they also cover the window frame in the closed position of the louvre window. Louvre windows of this type are particularly suitable for integration in a facade with an all-glass look. In addition to the mechanism of movement and the design of the slats, the document does not give any information on how to achieve bullet resistance.
- the invention is based on the object of creating a possibility that ensures bullet resistance in louvre windows with an all-glass look.
- a bullet-resistant glass louvre window construction for building installations.
- This contains a rectangular window frame, a first slat and at least one further slat.
- the first and further slats each contain a facade element and a rectangular slat frame with an axis of rotation.
- the facade elements are arranged on the lamellar frame and have an outer surface directed towards the outside of the building and an inner surface directed towards the inside of the building.
- the lamellar frames are arranged with the axes of rotation horizontally in the window frame. In a closed position, the slats have a window surface which is oriented parallel to the window frame and which is closed apart from function-related gaps and which covers the window frame.
- the first lamella has a first facade element and is arranged horizontally at the top of the window frame.
- Each additional lamella has a second facade element and is arranged horizontally below the first lamella on the window frame.
- the first facade element and the second facade element are each a laminated safety glass which has an inner viewing area and an edge area surrounding the inner viewing area.
- the edge area of the first facade element is completely covered on the inner surface with a first reinforcement frame.
- the edge area of the second facade element is completely covered on the inner surface with a second reinforcing frame and in the upper edge area with an additional cover strip.
- the first and the second facade element each have an inner pane on the inner surface and a central pane, preferably a polycarbonate pane, which connects the inner pane to the respective facade element in the visible area.
- the inner pane is larger than the center pane and smaller than the respective facade element.
- the lamellar frame of the first lamella has a reinforcing strip arranged at the top of the lamellar frame.
- the window frame has reinforcing inserts which, when the slats are in the closed position, reinforce an edge surrounding the window area.
- the glass louvre window construction further includes a mounting structure for securing the window frame in a building structure and a movement device for opening and closing the Slats.
- a fastening frame is arranged in the building structure as a mounting structure for the window frame.
- the first reinforcement frame, the second reinforcement frame, a first assembly frame, a second assembly frame, the cover strip, the reinforcement strip, the reinforcement insert and the fastening frame are weatherproof steel profiles with appropriately dimensioned cross-sections.
- the cover strip is expediently firmly connected to the second reinforcement frame between the second reinforcement frame and the inner pane and, in the closed position, overlaps with the first or second reinforcement frame of the first or further lamella arranged above it.
- the first and second reinforcing frames are each composed of four sections of the steel profile, which are glued to the respective facade element on the inner surface.
- the first assembly frame is advantageously composed of four sections of the steel profile that are screwed to the slat frame.
- the second mounting frame is particularly advantageously composed of three sections of the steel profile and the cover strip, which are screwed to the slat frame.
- the reinforcing strip is screwed to the lamella frame on the upper side of the lamella frame of the first lamella.
- the reinforcement insert is arranged circumferentially in a cavity in the window frame.
- the fastening frame for connecting the window frame to the building structure is expediently arranged within an opening in the building structure.
- the bullet-resistant glass slat window construction for building installations has a rectangular window frame 4, a first slat 1 and at least one further slat 2.
- the first lamella 1 and the further lamella 2 each contain a facade element and a rectangular lamella frame 3 with an axis of rotation A.
- the facade elements are arranged on the lamella frame 3. They have an outer surface E directed towards an outside of the building 81 and an inside surface F directed towards an inside 82 of the building.
- the louvre frames 3 are arranged horizontally in the window frame 4 with the axes of rotation A, so that the glass louvre window construction in a closed position of the first and further louvres 1 and 2 has a window surface oriented parallel to the window frame 4, closed except for the function-related column G and covering the window frame 4. Furthermore, the bullet-resistant glass louvre window construction has a fastening frame 5 for fastening the window frame 4 in a building structure 8 and a movement device (not shown in the figures) for opening and closing the first and further louvres 1 and 2.
- the bullet-resistant glass louvre window construction is intended in particular for installation on vertical or almost vertical building facades with an all-glass look in which, apart from the functional gap G between individual facade elements, there are no interruptions by materials other than those of the facade elements.
- the first lamella 1 is arranged horizontally at the top on the window frame 4 and has a first facade element 11.
- Each of the further slats 2 is arranged horizontally below the first slat 1 or below further slats 2 in the window frame 4 and has a second facade element 21.
- the movable mounting of the slats 1 and 2 in the window frame 4 and the movement device for driving the slats 1 and 2 are not described further here. They are designed according to the state of the art, for example from the aforementioned EP 2 666 951 B1 is known. It is essential that the slats 1 and 2 move away from the window frame 4 towards the outside of the building 81 in a combined rotating and opening movement of the axes of rotation A when they are opened.
- the two facade elements 11 and 21 are each rectangular glass elements made of laminated safety glass, which have the same width in the horizontal direction.
- the first facade element 11 differs from the second facade element 21 by a greater height in the vertical direction.
- the width is chosen so that the facade elements 11 and 21 cover the window frame 4 in the closed position.
- the height is selected so that all facade elements 11 and 21 together form the closed window area with which the window frame 4 is covered in the closed position, except for the remaining function-related gaps G.
- a lower edge of the window frame 4 is covered with the second facade element 21 of the further lamella 2 received at the bottom in the window frame 4.
- An upper edge of the window frame 4 is covered with the higher first facade element 11 of the first lamella 1.
- the first and second facade elements 11 and 21 have an inner viewing area S and an edge area R, wherein the edge area R surrounds the inner viewing area S in a framing manner.
- the viewing area S is framed by a dotted line for clarity. Everything outside the dotted line belongs to the edge area R of the facade elements 11 and 21.
- the edge region R On the inner surface F of the facade elements 11 and 21, the edge region R has an opaque coating.
- the coating is preferably a black enamel layer. All the structures behind the facade elements are optically covered by the coating, so that a clean look is achieved on the outside of the building 81.
- the first and second facade elements 11 and 21 in the viewing area S are designed as laminated, bullet-resistant composite safety glass.
- the first and second facade elements 11 and 21 are each firmly connected on the inner surface F to a center pane 6 and the center pane 6 is connected to an inner pane 7.
- the center pane 6 is a polycarbonate pane. It is slightly larger than the viewing area S defined by the edge area R. On the side facing the inner surface F, the side edges of the central pane 6 remain hidden behind the edge area R, so that the facade elements 11 and 21 have a clean look that is visible from the outside of the building 81 .
- the center disk 6 is connected to the inner disk 7.
- the inner pane 7 is a thermal insulating glass known from the prior art, made of two panes of glass separated by a spacer, which enclose a layer of air.
- the inner pane 7 is larger than the center pane 6, so that the spacer is located outside the side edges of the center pane 6 and is not visible from the outside of the building 81.
- the bullet-resistant effect in the field of vision S of the facade elements 11 and 21 can of course also be achieved by using other materials or a different arrangement of the layers of the laminated safety glass. It is essential that the required bullet-resistant effect is always achieved in the field of vision S.
- the facade elements 11 and 21 are reinforced in the edge region R with various flat steel profiles.
- the various flat steel profiles either consist of weather-resistant types of steel or are provided with a coating that makes the steel profiles weatherproof.
- the edge region R of the first facade element 11 is completely covered on the inner surface F with a first reinforcing frame 12.
- the first reinforcing frame 12 consists of four 8 mm thick flat steel profiles 70 ⁇ 8 mm, which are glued onto the side edges of the central pane 6 in the edge area R afterwards.
- the edge area R of the second facade element 21 is completely covered on the inner surface F with a second reinforcing frame 22.
- the second reinforcing frame 22 consists of three 8 mm thick flat steel profiles 70 ⁇ 8 mm, which cover the lower and the side edge areas R, and of one 8 mm Flat steel profile 7 x 8 mm, which covers the upper edge area R.
- the flat steel profiles are then glued to the side edges of the center disk 6 in the edge area R on the inner surface F.
- a cover strip 24 is arranged in the upper edge region R of the second facade element 21.
- the cover strip 24 is a 12 mm thick flat steel profile 26 x 12 mm, which is inserted into a remaining space between the second reinforcing frame 22 and the inner pane 7 and is glued to the inner pane 7, the second reinforcing frame 22 and the side edge of the center pane 6.
- Fig. 2 shows the first lamella 1 inserted at the top in the window frame 4 and the window frame 4 fastened in the building structure 8 in a sectional side view.
- the first lamella 1 is in the closed position.
- the axis of rotation A is oriented perpendicular to the plane of the drawing and is not shown.
- the window frame 4 and the lamellar frame 3 are constructed from combined aluminum-polyamide profiles which are provided with sealants on corresponding contact surfaces. This structure is known from the prior art and is not explained in more detail here.
- the lamella frame 3 of the first lamella 1 has a reinforcing strip 31 on its upper side.
- the reinforcement bar 31 is a square steel 18 x 18 mm.
- the reinforcing strip 31 is screwed to the aluminum profile of the louvre frame 3 and fills a gap between the louvre frame 3 and the window frame 4, provided that this does not restrict the mobility of the first louvre 1 in the window frame 4.
- a circumferential first mounting frame 13 is arranged on the lamellar frame 3.
- the first mounting frame 13 consists of four 12 mm thick flat steel profiles 37 ⁇ 12 mm, which are screwed onto the polyamide profile of the lamella frame 3 towards the outside of the building 81.
- the first facade element 11 is screwed to the lamella frame 3 via the first reinforcing frame 12.
- An opening framed by the first mounting frame 13 is larger than the inner pane 7, so that the first facade element 11 can be introduced into the lamella frame 3 from the outside 81 of the building.
- a reinforcing insert 41 is arranged around the window frame 4.
- the reinforcement insert 41 is a 6 mm thick flat steel profile 15 x 6 mm, which is inserted into a cavity in the polyamide profile. With the reinforcement insert 41 an existing space between the fastening frame 5 and the window frame 4 is covered.
- the fastening of the window frame 4 in the building structure 8 takes place with the fastening frame 5.
- the fastening frame 5 consists of a square steel 26 x 20 mm. It is inserted into an opening in the building structure 8 and screwed radially to the building structure 8.
- the window frame 4 is inserted into the fastening frame 5 from the outside of the building 81 and is brought into contact with the fastening frame 5. With the fastening frame 5, an existing space between the building structure 8 and the window frame 4 is filled.
- Fig. 3 shows a further slat 2 inserted into the window frame 4 in a sectional side view.
- the other lamella 2 is in the closed position.
- the axis of rotation A is oriented perpendicular to the plane of the drawing and is not shown.
- a second mounting frame 23 is arranged around the lamellar frame 3.
- the second mounting frame 23 consists of three 12 mm thick flat steel profiles 37 x 12 mm and the cover strip 24, which are screwed onto the polyamide profile of the lamella frame 3 towards the outside of the building 81.
- the second facade element 21 introduced into the lamella frame 3 from the outside 81 of the building is screwed to the lamella frame 3 via the second reinforcement frame 22.
- the first lamella 1 is arranged above the further lamella 2 and another lamella 2 is arranged below the further lamella 2, each of which is only shown in part. It can be clearly seen that the first lamella 1 overlaps with the further lamella 2 and the further lamella 2 overlaps in the vertical direction with the further lamella 2 arranged therebelow.
- the overlap is given by the first and second Facade elements 11 and 21 reached, the first facade element 11 with its lower edge covering part of the lamella frame 3 of the further lamella 2 arranged below.
- Each second facade element 21 covers with its lower edge part of the lamella frame 3 of the further lamella 2 arranged below it.
- the overlap continues up to the further lamella 2 received at the bottom in the window frame 4, the second facade element 21 of which covers the lower edge of the window frame 4.
- the facade elements 11 and 21 thus form the closed window area, which is only interrupted by the function-related column G visible from the outside of the building 81.
- the bullet-resistant effect in the area of the function-related gap G is achieved in that the first reinforcement frame 12 and the second reinforcement frame 22 each have a partial overlap with the cover strip 24 of the further lamella 2 arranged below.
- the bullet-resistant effect outside the field of vision S of the facade elements 11 and 21, even if the bullet does not hit the outer surface E perpendicularly, is achieved by the arrangement of the overlapping individual elements of the glass louvre window construction.
- These elements include the first and second reinforcement frames 12 and 22, the first and second mounting frames 13 and 23, the cover strip 24, the reinforcement strip 31, the reinforcement insert 41 and the fastening frame 5.
- the bullet-resistant effect is achieved according to the same principle described in the embodiment described above, if instead of the glass louvre window construction, a vent window with only a first facade element 11 is built, in which a first lamella 1 is received in the window frame 4 .

Description
Die Erfindung betrifft eine durchschusshemmende Glaslamellenfensterkonstruktion für Gebäudeinstallationen, insbesondere für senkrechte Fassaden mit einer geschlossenen Ganzglasoptik an der Gebäudeaußenseite.The invention relates to a bullet-resistant glass louvre window construction for building installations, in particular for vertical facades with a closed all-glass look on the outside of the building.
Lamellenfenster weisen in der Regel einen rechteckigen Fensterrahmen auf, in dem mehrere Lamellen parallel neben- oder übereinander angeordnet sind. Im geschlossenen Zustand des Lamellenfensters bilden die Lamellen eine zum Fensterrahmen planparallele Fensterfläche, welche die Öffnung des Fensterrahmens verschließt. Die Lamellen sind an im Fensterrahmen befestigten Drehachsen gelagert und können zum Öffnen des Lamellenfensters über einen gleichzeitig auf alle Lamellen wirkenden Antriebsmechanismus synchron in einen geöffneten Zustand geschwenkt werden.Louvre windows usually have a rectangular window frame in which several lamellas are arranged parallel next to or one above the other. When the louvre window is closed, the louvres form a window surface which is plane-parallel to the window frame and which closes the opening of the window frame. The slats are mounted on axes of rotation fixed in the window frame and, in order to open the slat window, can be swiveled synchronously into an open state by means of a drive mechanism acting simultaneously on all slats.
Aus dem Stand der Technik sind bereits Lamellenfenster bekannt, bei denen innerhalb des Fensterrahmens eine Ganzglasoptik erreicht wird.Louvre windows are already known from the prior art in which an all-glass look is achieved within the window frame.

Die Gebrauchsmusterschrift
Bei den beiden zuvor genannten Lösungen sind die Fensterflächen der geschlossenen Lamellen von dem Fensterrahmen eingefasst, sodass die an einer Fassade montierten Fensterrahmen stets sichtbar bleiben. Durch die offenbarte Art der drehbaren Lagerung, bei der ein Teil der Lamelle zur Innenseite und ein Teil der Lamelle zur Außenseite des Fensterrahmens geschwenkt wird, ist es prinzipbedingt nicht möglich, den Fensterrahmen mit einem auf dem Lamellenrahmen montierten Fassadenelement abzudecken. Eine Fassade in Ganzglasoptik, bei der der Fensterrahmen hinter den Fassadenelementen verborgen bleibt, kann so nicht erreicht werden. Maßnahmen zur Durchschusshemmung sind ebenfalls nicht vorgesehen.In the case of the two aforementioned solutions, the window surfaces of the closed slats are framed by the window frame, so that the window frames mounted on a facade always remain visible. Due to the disclosed type of rotatable mounting, in which part of the lamella is pivoted to the inside and part of the lamella to the outside of the window frame, it is in principle not possible to cover the window frame with a facade element mounted on the lamella frame. A facade with an all-glass look, in which the window frame remains hidden behind the facade elements, cannot be achieved in this way. Bullet resistance measures are also not provided.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, die bei Lamellenfenstern in Ganzglasoptik eine Durchschusshemmung gewährleistet.The invention is based on the object of creating a possibility that ensures bullet resistance in louvre windows with an all-glass look.
Erfindungsgemäß wird die Aufgabe gelöst durch eine durchschusshemmende Glaslamellenfensterkonstruktion für Gebäudeinstallationen. Diese enthält einen rechteckigen Fensterrahmen, eine erste Lamelle und mindestens eine weitere Lamelle. Die erste und weitere Lamelle enthalten jeweils ein Fassadenelement und einen rechteckigen Lamellenrahmen mit einer Drehachse. Die Fassadenelemente sind auf dem Lamellenrahmen angeordnet und weisen eine zu einer Gebäudeaußenseite gerichtete Außenoberfläche und eine zu einer Gebäudeinnenseite gerichtete Innenoberfläche auf. Die Lamellenrahmen sind mit den Drehachsen horizontal in dem Fensterrahmen angeordnet. Die Lamellen weisen in einer Schließstellung eine parallel zum Fensterrahmen orientierte und bis auf funktionsbedingte Spalte geschlossene und den Fensterrahmen abdeckende Fensterfläche auf. Die erste Lamelle weist ein erstes Fassadenelement auf und ist horizontal zuoberst am Fensterrahmen angeordnet. Jede weitere Lamelle weist jeweils ein zweites Fassadenelement auf und ist horizontal unterhalb der ersten Lamelle am Fensterrahmen angeordnet. Das erste Fassadenelement und das zweite Fassadenelement sind jeweils ein Verbundsicherheitsglas, das einen inneren Sichtbereich und einen den inneren Sichtbereich umgebenden Randbereich aufweist. Der Randbereich des ersten Fassadenelements ist auf der Innenoberfläche vollständig mit einem ersten Verstärkungsrahmen abgedeckt. Der Randbereich des zweiten Fassadenelements ist auf der Innenoberfläche vollständig mit einem zweiten Verstärkungsrahmen und im oberen Randbereich mit einer zusätzlichen Abdeckleiste abgedeckt. Das erste und das zweite Fassadenelement weisen an der Innenoberfläche jeweils eine Innenscheibe und eine die Innenscheibe mit dem jeweiligen Fassadenelement im Sichtbereich verbindende Mittenscheibe, vorzugsweise eine Polycarbonatscheibe, auf. Die Innenscheibe ist größer als die Mittenscheibe und kleiner als das jeweilige Fassadenelement. Der Lamellenrahmen der ersten Lamelle weist eine oben am Lamellenrahmen angeordnete Verstärkungsleiste auf. Der Fensterrahmen weist Verstärkungseinlagen auf, die in der Schließstellung der Lamellen einen die Fensterfläche umgebenden Rand verstärken. Die Glaslamellenfensterkonstruktion enthält weiterhin eine Montagestruktur zum Befestigen des Fensterrahmens in einer Gebäudestruktur und eine Bewegungseinrichtung zum Öffnen und Schließen der Lamellen. Als Montagestruktur für den Fensterrahmen ist ein Befestigungsrahmen in der Gebäudestruktur angeordnet.According to the invention, the object is achieved by a bullet-resistant glass louvre window construction for building installations. This contains a rectangular window frame, a first slat and at least one further slat. The first and further slats each contain a facade element and a rectangular slat frame with an axis of rotation. The facade elements are arranged on the lamellar frame and have an outer surface directed towards the outside of the building and an inner surface directed towards the inside of the building. The lamellar frames are arranged with the axes of rotation horizontally in the window frame. In a closed position, the slats have a window surface which is oriented parallel to the window frame and which is closed apart from function-related gaps and which covers the window frame. The first lamella has a first facade element and is arranged horizontally at the top of the window frame. Each additional lamella has a second facade element and is arranged horizontally below the first lamella on the window frame. The first facade element and the second facade element are each a laminated safety glass which has an inner viewing area and an edge area surrounding the inner viewing area. The edge area of the first facade element is completely covered on the inner surface with a first reinforcement frame. The edge area of the second facade element is completely covered on the inner surface with a second reinforcing frame and in the upper edge area with an additional cover strip. The first and the second facade element each have an inner pane on the inner surface and a central pane, preferably a polycarbonate pane, which connects the inner pane to the respective facade element in the visible area. The inner pane is larger than the center pane and smaller than the respective facade element. The lamellar frame of the first lamella has a reinforcing strip arranged at the top of the lamellar frame. The window frame has reinforcing inserts which, when the slats are in the closed position, reinforce an edge surrounding the window area. The glass louvre window construction further includes a mounting structure for securing the window frame in a building structure and a movement device for opening and closing the Slats. A fastening frame is arranged in the building structure as a mounting structure for the window frame.
Vorzugsweise sind der erste Verstärkungsrahmen, der zweite Verstärkungsrahmen, ein erster Montagerahmen, ein zweiter Montagerahmen, die Abdeckleiste, die Verstärkungsleiste, die Verstärkungseinlage und der Befestigungsrahmen witterungsbeständige Stahlprofile mit entsprechend dimensionierten Querschnitten.The first reinforcement frame, the second reinforcement frame, a first assembly frame, a second assembly frame, the cover strip, the reinforcement strip, the reinforcement insert and the fastening frame are weatherproof steel profiles with appropriately dimensioned cross-sections.
Zweckmäßig ist die Abdeckleiste zwischen dem zweiten Verstärkungsrahmen und der Innenscheibe fest mit dem zweiten Verstärkungsrahmen verbunden und weist in der Schließstellung eine Überlappung mit dem jeweils ersten oder zweiten Verstärkungsrahmen der darüber angeordneten ersten oder weiteren Lamelle auf.The cover strip is expediently firmly connected to the second reinforcement frame between the second reinforcement frame and the inner pane and, in the closed position, overlaps with the first or second reinforcement frame of the first or further lamella arranged above it.
In einer verallgemeinerten Variante ist der erste und zweite Verstärkungsrahmen jeweils aus vier Abschnitten des Stahlprofils zusammengesetzt, die an der Innenoberfläche mit dem jeweiligen Fassadenelement verklebt sind.In a generalized variant, the first and second reinforcing frames are each composed of four sections of the steel profile, which are glued to the respective facade element on the inner surface.
Vorteilhaft ist der erste Montagerahmen jeweils aus vier Abschnitten des Stahlprofils zusammengesetzt, die am Lamellenrahmen verschraubt sind.The first assembly frame is advantageously composed of four sections of the steel profile that are screwed to the slat frame.
Besonders vorteilhaft ist der zweite Montagerahmen jeweils aus drei Abschnitten des Stahlprofils und aus der Abdeckleiste zusammengesetzt, die am Lamellenrahmen verschraubt sind.The second mounting frame is particularly advantageously composed of three sections of the steel profile and the cover strip, which are screwed to the slat frame.
In einer möglichen Ausgestaltung ist die Verstärkungsleiste an der Oberseite des Lamellenrahmens der ersten Lamelle mit dem Lamellenrahmen verschraubt.In one possible embodiment, the reinforcing strip is screwed to the lamella frame on the upper side of the lamella frame of the first lamella.
In einer speziellen Ausgestaltung ist die Verstärkungseinlage umlaufend in einem Hohlraum des Fensterrahmens angeordnet.In a special embodiment, the reinforcement insert is arranged circumferentially in a cavity in the window frame.
Zweckmäßig ist der Befestigungsrahmen zur Verbindung des Fensterrahmens mit der Gebäudestruktur innerhalb einer Öffnung der Gebäudestruktur angeordnet.The fastening frame for connecting the window frame to the building structure is expediently arranged within an opening in the building structure.

Gemäß
Die durchschusshemmende Glaslamellenfensterkonstruktion ist insbesondere für den Einbau an senkrechten oder nahezu senkrecht verlaufenden Gebäudefassaden mit einer Ganzglasoptik vorgesehen, in der bis auf die funktionsbedingten Spalte G zwischen einzelnen Fassadenelementen keine Unterbrechungen durch andere Materialien als die der Fassadenelemente vorhanden sind.The bullet-resistant glass louvre window construction is intended in particular for installation on vertical or almost vertical building facades with an all-glass look in which, apart from the functional gap G between individual facade elements, there are no interruptions by materials other than those of the facade elements.
Die erste Lamelle 1 ist horizontal zuoberst am Fensterrahmen 4 angeordnet und weist ein erstes Fassadenelement 11 auf. Jede der weiteren Lamellen 2 ist horizontal unterhalb der ersten Lamelle 1 oder unterhalb weiterer Lamellen 2 im Fensterrahmen 4 angeordnet und weist ein zweites Fassadenelement 21 auf.The
Die bewegliche Aufnahme der Lamellen 1 und 2 im Fensterrahmen 4 und die Bewegungseinrichtung zum Antreiben der Lamellen 1 und 2 werden hier nicht weiter ausgeführt. Sie sind entsprechend dem Stand der Technik ausgeführt, der zum Beispiel aus der vorgenannten
Die beiden Fassadenelemente 11 und 21 sind jeweils rechteckige Glaselemente aus Verbundsicherheitsglas, die in horizontaler Richtung eine gleiche Breite aufweisen. Das erste Fassadenelement 11 unterscheidet sich gegenüber dem zweiten Fassadenelement 21 durch eine größere Höhe in vertikaler Richtung. Die Breite ist so gewählt, dass die Fassadenelemente 11 und 21 den Fensterrahmen 4 in der Schließstellung abdecken. Die Höhe ist so gewählt, dass alle Fassadenelemente 11 und 21 zusammen die geschlossene Fensterfläche ausbilden, mit welcher der Fensterrahmen 4 in der Schließstellung, bis auf die verbleibenden funktionsbedingten Spalte G, abgedeckt wird. Ein unterer Rand des Fensterrahmens 4 wird mit dem zweiten Fassadenelement 21 der zuunterst im Fensterrahmen 4 aufgenommenen weiteren Lamelle 2 abdeckt. Ein oberer Rand des Fensterrahmens 4 wird mit dem höheren ersten Fassadenelement 11 der ersten Lamelle 1 abgedeckt.The two
Die ersten und zweiten Fassadenelemente 11 und 21 weisen einen inneren Sichtbereich S und einen Randbereich R auf, wobei der Randbereich R den inneren Sichtbereich S einrahmend umgibt. In
Auf der Innenoberfläche F der Fassadenelemente 11 und 21 weist der Randbereich R eine undurchsichtige Beschichtung auf. Die Beschichtung ist bevorzugt eine schwarze Emailleschicht. Durch die Beschichtung werden alle hinter den Fassadenelementen liegenden Strukturen optisch abgedeckt, sodass auf der Gebäudeaußenseite 81 eine saubere Optik erreicht wird.On the inner surface F of the
Wie in
Die Mittenscheibe 6 ist eine Polycarbonatscheibe. Sie ist geringfügig größer als der durch den Randbereich R definierte Sichtbereich S. Auf der Seite zur Innenoberfläche F bleiben die Seitenränder der Mittenscheibe 6 hinter dem Randbereich R verborgen, sodass an den Fassadenelementen 11 und 21 eine von der Gebäudeaußenseite 81 sichtbare, saubere Optik erreicht wird.The
Auf der anderen Seite ist die Mittenscheibe 6 mit der Innenscheibe 7 verbunden. Die Innenscheibe 7 ist ein aus dem Stand der Technik bekanntes Thermoisolierglas aus zwei mit einem Abstandshalter getrennten Glasscheiben, die eine Luftschicht einschließen. Die Innenscheibe 7 ist größer als die Mittenscheibe 6, sodass sich der Abstandshalter außerhalb der Seitenränder der Mittenscheibe 6 befindet und von der Gebäudeaußenseite 81 nicht sichtbar ist.On the other hand, the
An dieser Stelle wird darauf hingewiesen, dass die durchschusshemmende Wirkung im Sichtbereich S der Fassadenelemente 11 und 21 selbstverständlich auch durch Verwendung anderer Materialien oder eine andere Anordnung der Schichten des Verbundsicherheitsglases erreicht werden kann. Wesentlich ist, dass im Sichtbereich S stets die geforderte durchschusshemmende Wirkung erreicht wird.At this point it is pointed out that the bullet-resistant effect in the field of vision S of the
Zum Erreichen der durchschusshemmenden Wirkung außerhalb des Sichtbereichs S sind die Fassadenelemente 11 und 21 im Randbereich R mit verschiedenen Flachstahlprofilen verstärkt. Die verschiedenen Flachstahlprofile bestehen entweder aus witterungsbeständigen Stahlsorten oder sind mit einer Beschichtung versehen, welche die Stahlprofile witterungsfest macht.To achieve the bullet-resistant effect outside the field of vision S, the
Der Randbereich R des ersten Fassadenelements 11 ist auf der Innenoberfläche F mit einem ersten Verstärkungsrahmen 12 vollständig abgedeckt. Der erste Verstärkungsrahmen 12 besteht aus vier 8 mm dicken Flachstahlprofilen 70 x 8 mm, welche, an die Seitenränder der Mittenscheibe 6 anschließend, im Randbereich R aufgeklebt sind.The edge region R of the
Der Randbereich R des zweiten Fassadenelements 21 ist auf der Innenoberfläche F mit einem zweiten Verstärkungsrahmen 22 vollständig abgedeckt. Der zweite Verstärkungsrahmen 22 besteht aus drei 8 mm dicken Flachstahlprofilen 70 x 8 mm, welche den unteren und die seitlichen Randbereiche R abdecken, und aus einem 8 mm Flachstahlprofil 7 x 8 mm, das den oberen Randbereich R abdeckt. Die Flachstahlprofile sind, an die Seitenränder der Mittenscheibe 6 anschließend, im Randbereich R auf die Innenoberfläche F aufgeklebt.The edge area R of the
Zusätzlich zum zweiten Verstärkungsrahmen 22 ist im oberen Randbereich R des zweiten Fassadenelements 21 eine Abdeckleiste 24 angeordnet. Die Abdeckleiste 24 ist ein 12 mm dickes Flachstahlprofil 26 x 12 mm, das in einen verbleibenden Zwischenraum zwischen dem zweiten Verstärkungsrahmen 22 und der Innenscheibe 7 eingesetzt ist und mit der Innenscheibe 7, dem zweiten Verstärkungsrahmen 22 und dem Seitenrand der Mittenscheibe 6 verklebt ist.In addition to the second reinforcing
Der Fensterrahmen 4 und der Lamellenrahmen 3 sind aus kombinierten Aluminium-Polyamid-Profilen aufgebaut, die an entsprechenden Anlageflächen mit Dichtmitteln versehen sind. Dieser Aufbau ist aus dem Stand der Technik bekannt und wird hier nicht näher erläutert.The
Abweichend vom Stand der Technik weist der Lamellenrahmen 3 der ersten Lamelle 1 an seiner Oberseite eine Verstärkungsleiste 31 auf. Die Verstärkungsleiste 31 ist ein Vierkantstahl 18 x 18 mm. Die Verstärkungsleiste 31 ist mit dem Aluminiumprofil des Lamellenrahmens 3 verschraubt und füllt einen zwischen dem Lamellenrahmen 3 und dem Fensterrahmen 4 bestehenden Zwischenraum aus, soweit dadurch nicht die Beweglichkeit der ersten Lamelle 1 im Fensterrahmen 4 eingeschränkt wird.In a departure from the prior art, the
Am Lamellenrahmen 3 ist ein umlaufender erster Montagerahmen 13 angeordnet. Der erste Montagerahmen 13 besteht aus vier 12 mm dicken Flachstahlprofilen 37 x 12 mm, die zur Gebäudeaußenseite 81 hin auf das Polyamidprofil des Lamellenrahmens 3 aufgeschraubt sind. Am ersten Montagerahmen 13 ist das erste Fassadenelement 11 über den ersten Verstärkungsrahmen 12 mit dem Lamellenrahmen 3 verschraubt. Eine vom ersten Montagerahmen 13 eingerahmte Öffnung ist größer als die Innenscheibe 7, sodass das erste Fassadenelement 11 von der Gebäudeaußenseite 81 her in den Lamellenrahmen 3 eingeführt werden kann.A circumferential first mounting
Zur Unterstützung der durchschusshemmenden Wirkung ist im Fensterrahmen 4 umlaufend eine Verstärkungseinlage 41 angeordnet. Die Verstärkungseinlage 41 ist ein 6 mm dickes Flachstahlprofil 15 x 6 mm, das in einen Hohlraum des Polyamidprofils eingeschoben ist. Mit der Verstärkungseinlage 41 wird ein zwischen dem Befestigungsrahmen 5 und dem Fensterrahmen 4 bestehender Zwischenraum abgedeckt.To support the bullet-resistant effect, a reinforcing
Die Befestigung des Fensterrahmens 4 in der Gebäudestruktur 8 erfolgt mit dem Befestigungsrahmen 5. Der Befestigungsrahmen 5 besteht aus einem Vierkantstahl 26 x 20 mm. Er ist in eine Öffnung der Gebäudestruktur 8 eingesetzt und radial mit der Gebäudestruktur 8 verschraubt. Der Fensterrahmen 4 wird von der Gebäudeaußenseite 81 her in den Befestigungsrahmen 5 eingesetzt und am Befestigungsrahmen 5 zur Anlage gebracht. Mit dem Befestigungsrahmen 5 wird ein zwischen der Gebäudestruktur 8 und dem Fensterrahmen 4 bestehender Zwischenraum ausgefüllt.The fastening of the
Am Lamellenrahmen 3 ist umlaufend ein zweiter Montagerahmen 23 angeordnet. Der zweite Montagerahmen 23 besteht aus drei 12 mm dicken Flachstahlprofilen 37 x 12 mm und der Abdeckleiste 24, die zur Gebäudeaußenseite 81 hin auf das Polyamidprofil des Lamellenrahmens 3 aufgeschraubt sind. Am zweiten Montagerahmen 23 ist das von der Gebäudeaußenseite 81 her in den Lamellenrahmen 3 eingeführte zweite Fassadenelement 21 über den zweiten Verstärkungsrahmen 22 mit dem Lamellenrahmen 3 verschraubt.A
Oberhalb der weiteren Lamelle 2 ist die erste Lamelle 1 und unterhalb der weiteren Lamelle 2 ist eine weitere Lamelle 2 angeordnet, die jeweils nur in einer Teildarstellung gezeigt sind. Es ist gut zu erkennen, dass sich die erste Lamelle 1 mit der weiteren Lamelle 2 und die weitere Lamelle 2 mit der darunter angeordneten weiteren Lamelle 2 in vertikaler Richtung überlappt. Die Überlappung wird durch die ersten und zweiten Fassadenelemente 11 und 21 erreicht, wobei das erste Fassadenelement 11 mit seiner Unterkante einen Teil des Lamellenrahmens 3 der darunter angeordneten weiteren Lamelle 2 überdeckt. Jedes zweite Fassadenelement 21 überdeckt mit seiner Unterkante einen Teil des Lamellenrahmens 3 der darunter angeordneten weiteren Lamelle 2. Die Überlappung setzt sich bis zu der zuunterst im Fensterrahmen 4 aufgenommenen weiteren Lamelle 2 fort, deren zweites Fassadenelement 21 den unteren Rand des Fensterrahmens 4 abdeckt. Die Fassadenelemente 11 und 21 bilden so die geschlossene Fensterfläche, die nur durch die von der Gebäudeaußenseite 81 her sichtbaren funktionsbedingten Spalte G unterbrochen ist.The
Die durchschusshemmende Wirkung im Bereich der funktionsbedingten Spalte G wird dadurch erreicht, dass der erste Verstärkungsrahmen 12 bzw. der zweite Verstärkungsrahmen 22 jeweils eine teilweise Überlappung mit der Abdeckleiste 24 der darunter angeordneten weiteren Lamelle 2 aufweist.The bullet-resistant effect in the area of the function-related gap G is achieved in that the
Die durchschusshemmende Wirkung außerhalb des Sichtbereichs S der Fassadenelemente 11 und 21, auch bei nicht senkrecht auf die Außenoberfläche E auftreffendem Beschuss, wird durch die Anordnung der sich überlappenden einzelnen Elemente der Glaslamellenfensterkonstruktion erreicht. Zu diesen Elementen gehören der erste und zweite Verstärkungsrahmen 12 und 22, der erste und zweite Montagerahmen 13 und 23, die Abdeckleiste 24, die Verstärkungsleiste 31, die Verstärkungseinlage 41 und der Befestigungsrahmen 5.The bullet-resistant effect outside the field of vision S of the
In einer nicht in den Figuren gezeigten Ausführung wird die durchschusshemmende Wirkung nach dem gleichen, im zuvor beschriebenen Ausführungsbeispiel beschriebenen Prinzip erreicht, wenn anstatt der Glaslamellenfensterkonstruktion ein Ausstellfenster mit nur einem ersten Fassadenelement 11 aufgebaut wird, bei dem im Fensterrahmen 4 eine erste Lamelle 1 aufgenommen ist.In an embodiment not shown in the figures, the bullet-resistant effect is achieved according to the same principle described in the embodiment described above, if instead of the glass louvre window construction, a vent window with only a
