Description

The invention relates to a building with at least one building ceiling, a window frame and a roller shutter box or a shutter box, which is arranged between the window frame and the building ceiling. In addition, the invention relates to a fastening element for fastening a window frame to a building ceiling of a building and a method for fixing a window frame to a building ceiling of a building.

There are structures known to have on their facade as part of the building envelope windows in front of which a roller shutter or a blind is attached from the outside. This requires that a roller shutter box or a shutter box is arranged above the window frame. The roller shutter box or shutter box serves to accommodate the rolling armor or the slats of the blind and forms in a roller shutter an enclosure around the rolling room. In the rolling room, the shaft is arranged around which the roller shutter is wound, or the space in which the slats of the blind or the rolling armor of the shutter are taken up or rolled up. In order to achieve good thermal insulation, such roller shutter boxes or blind boxes are insulated. As insulating material, for example, foamed polystyrene or another material is used, which has a good insulating properties.

In buildings with large windows, correspondingly large wind loads act on the window surface, which must be recorded. This can, since the window sash is attached on the upper side over its length only on the attached roller shutter or shutter box, lead to problems. Because it is difficult to achieve a stable attachment of the window frame to the existing insulating material or insulating material having shutter box. Therefore, recorded high wind loads can be insufficient on the Roller shutter box can be transmitted, which is why it can come to movements of the window relative to the roller shutter or shutter box, which manifests itself in noise and can lead to damage to the window or the shutter box and the surrounding plaster.

The invention is therefore an object of the invention to provide a structure in which the attachment of the window frame is improved.

To solve this problem is provided according to the invention in a building of the type mentioned that the structure has at least one fastener with a mounting portion, an anchoring portion and a connecting portion with the anchoring portion connecting portion, wherein the window frame connected to the mounting portion and the anchoring portion in the Building ceiling is anchored and the connecting portion passes through the shutter box or the shutter box.

According to the invention it is therefore proposed that the window frame is connected to the fastening element and the forces that are absorbed, for example, by wind load from the window, are transmitted through the fastener in the building ceiling of the building. The fastener engages with its connecting portion to the shutter box or the shutter box so that it does not have to absorb the forces acting on the window.

On the other hand, the force is transmitted from the window to the fastening section to which the window frame is fastened, which in turn transmits the force via the connecting section into the anchoring section and thus into the building ceiling. Since the anchoring portion is anchored in the building ceiling, a high absorption of forces is possible in particular compared to a connection of the window frame to a roller shutter box or shutter box. The window frame is thus connected via the fastener fixed to the building ceiling.

In particular, the attachment portion may be formed such that when using a roller shutter box of the rolling room of the shutter box is not penetrated by the connecting portion, but the mounting portion protrudes so far in the direction of the building inside that the connecting portion extend vertically upwards through the disposed behind the rolling room insulation material and thus can penetrate the roller shutter box outside of the rolling room.

Particularly preferably, it can be provided in the construction according to the invention that the fastening section is designed as a fastening plate, in particular as a pole lug. Of course, the mounting plate has suitable openings to secure it to the window frame. In particular, the fastening plate can be connected to the window frame by means of suitable fastening means, such as screws. At its end, which is opposite to the portion where the mounting plate is connected to the window frame, this has a portion to which the connecting portion can be connected. The mounting plate is, as described above, in particular designed so that the rolling space of the roller shutter box does not need to be penetrated by the connecting element. This offers the advantage that roller shutter boxes that are already in use can continue to be used or installed, since they are not affected by the mounting plate and the connecting portion, for example in their rolling room.

A further development of the building according to the invention can provide that the fastening section is detachable from the connecting section and / or the window frame or that the fastening section is formed integrally with the connecting section. Advantageously, the attachment portion of the connecting portion and the window frame is detachable, so that it can be solved, for example, to access an inspection opening in the shutter box or assembly work on the window frame. However, it is also possible, the attachment portion integral with the Form connecting portion, so that they can be installed as a component in the building according to the invention.

Likewise, it may preferably be provided that the anchoring portion is detachably arranged on the connecting portion, in particular screwed, is.

Of course, further positive or non-positive connection mechanisms between the anchoring portion and the connecting portion are possible. The detachable connection between anchoring portion and connecting portion has the advantage that these can be transported disassembled before assembly. In an installation of the fastener in a new building, this is particularly preferred, since the assembly is preferably such that the connecting portion is introduced into the shutter box and spaced above the shutter box at a distance of about 4 to 5 cm from a Filigrandecke or of an intended Filigree corner spaced from the shutter box exit. There, the anchoring portion can be connected to the connecting portion. By separately forming the two sections, a transport of the fastening elements is possible more efficiently.

Particularly preferably, the anchoring portion has a Y-shaped or a V-shaped cross section. The Y-shape or V-shape shape significantly increases the anchoring strength with the concrete in which the anchoring portion is cast. Furthermore, it can be provided on the anchoring section that it is perforated or has openings which allow a further improvement of the inflow of the concrete or the entanglement of the anchoring section with the concrete.

Alternatively, it is possible, especially in old buildings or buildings with existing building ceiling in which the fastener is to be introduced into an existing building that the anchoring portion is glued in the ceiling or connected to a dowel, which is clamped or braced in the building ceiling , This is done in the existing Building ceiling through the shutter box or the blind box through a hole drilled into which the anchoring portion can be inserted and glued, or into which a dowel can be introduced, with the anchoring portion is connectable, so that the dowel braced in connected anchoring portion in the building ceiling ,

The connecting portion may in particular be tubular, but it is also possible to form this in the form of a flat strip-like material, or a square material. In general, all shapes are possible as long as the connecting portion has a stable connection between the attachment portion and the anchoring portion and can pass through the roller shutter box, in particular through an opening, in particular a hole through the roller shutter box.

Likewise, it can be provided on the building according to the invention that the anchoring section and / or the connecting section and / or the fastening section of the fastening element are integrally formed. Depending on the requirement, the anchoring section and the connecting section can thus be formed integrally or the fastening section can be formed integrally with the connecting section. Of course, all combinations of one-piece or multi-part connection of the individual sections are possible.

Finally, it is preferable to provide on the structure according to the invention that the connecting section passes through the roller shutter box or shutter box such that the end of the connecting section to be connected to the anchoring section is defined by a filigree corner or semi-finished ceiling in the direction of the building envelope of the building, in particular 4-5 cm , Is arranged at a distance. As described above, the connecting portion is guided through the roller shutter box or the shutter box in particular through a hole in this. Below the roller shutter box, the connecting portion is connected to the mounting portion, or is formed integrally therewith. Above the roller shutter box, in the area in which a Filigrandecke is placed on the masonry, and thus on the shutter box or the shutter box, in particular 4 - 5 cm spaced from the edge of the filigree corner, the connecting portion protrudes from the shutter box. This can be formed in a simple embodiment as a pipe with an internal thread into which the anchoring section can be screwed above the roller shutter box. Of course, it is also possible to connect the anchoring portion with a suitable fastening means with the connecting portion. Of course, it is also possible to first connect the connecting portion with the anchoring portion and to introduce this from above into the hole in the shutter box and then to connect the mounting portion from below with the connecting portion.

If the attachment portion with the window frame and the connecting portion and the connecting portion connected to the anchoring portion, it can be poured, for example, in-situ concrete after appropriate shells of the building, the building ceiling. The anchoring section protrudes from the connecting section pointing the way in the direction of the building ceiling or is arranged in the building ceiling. By pouring the anchoring section in the in-situ concrete this is connected to the building ceiling, resulting in a particularly stable connection. It is also possible to connect the anchoring section before the finished building ceiling with a reinforcement or reinforcement in the building ceiling.

Depending on the size of the window front, which is to be connected to the building ceiling, it is of course possible to provide several fasteners to the building according to the invention. The distance between two fastening elements can be adapted to the case of need, in particular, the distance may be less than one meter, in particular in the range of 60 to 90 cm. From this distance or the preferences of the user, there are the number of fasteners that have a Rohbaulichte of the window must be arranged distributed, so that a corresponding force acting on a window surface, safely distributed to the fasteners and thus can be passed into the building ceiling.

In addition, the invention relates to a fastening element for fastening a window frame to a building ceiling of a building, which has a fastening section for connecting the fastening element to a window frame, an anchoring section for anchoring the fastening element in the building ceiling of the building and a connecting section connecting the fastening section with the anchoring section, wherein the connecting portion in a fixed state of the fastener, a roller shutter box or a shutter box of the building, which is arranged between the window frame and the building ceiling, passes through. Of course, the fastener according to the invention has all the features that have been described with regard to the construction according to the invention.

• Einbringen des Verbindungsabschnitts in den Rollladenkasten oder in den Jalousiekasten, der zwischen dem Fensterrahmen und der Gebäudedecke angeordnet ist
• Befestigen des Fensterrahmens an dem Befestigungsabschnitt
• Verankern des Verankerungsabschnitts in der Gebäudedecke.

In addition, the invention relates to a method for attaching a window frame to a building ceiling of a building, comprising the steps:

• Inserting the connecting portion in the shutter box or in the shutter box, which is arranged between the window frame and the building ceiling
• Attach the window frame to the attachment portion
• Anchoring the anchoring section in the building ceiling.

The order of the individual process steps is of course arbitrary. Thus it is at the discretion of the person skilled in the art first to introduce the connecting section into the roller shutter box or into the shutter box which is arranged between the window frame and the building ceiling and then to fasten the fastening section to the window frame and / or the connecting section and subsequently to the anchoring section with the connecting section connect to. However, it is also possible the Join anchoring portion and the connecting portion and then connect this with the mounting portion and this in turn to the window frame. These steps are largely concatenated arbitrarily, but are at least partially determined depending on the use of the fastener, for example, in a new building or in an old building, in their order. This will be described in detail below.

Preferably, the attachment portion is formed integrally with the connection portion or is detachably attached to the connection portion. In the alternative, in which the connecting portion is releasably secured to the mounting portion, it is particularly advantageous that this, for example, to allow access to a revision opening in the shutter box or shutter box, is detachable from the connecting portion.

In particular, with regard to the attachment of the window frame in a new building or the introduction of the fastener in a new construction can be provided in the inventive method that after the introduction of the connecting portion in the roller shutter box or in the shutter box, the anchoring portion attached to the connecting portion and then the anchoring portion anchored in the building ceiling, in particular cast in situ concrete, is. When carrying out the method according to the invention in the case of a new building, the greatest freedom is thus given as to the order in which the method steps are carried out. Thus, it is firstly possible to first establish the connection between the fastening section and the connecting section and to introduce it from below into the opening in the roller shutter box and then to attach the window frame to the fastening section and / or the anchoring section at the connecting section, to introduce it into the bore. Furthermore, it is also possible first to attach the anchoring section to the connecting section and then to cast the anchoring section into in-situ concrete or into the building ceiling. Only then it is also possible the Attach mounting portion to the connecting portion and connect the window frame with the mounting portion. It is thus clear that the order of the method steps depends essentially on the preference of the user.

In addition, especially with regard to old buildings or buildings in which a building ceiling and a roller shutter box or shutter box is permanently installed, the method can also be developed to the effect that the anchoring portion is inserted into an existing building ceiling of the building and anchored there, wherein the connecting portion subsequently connected to the anchoring portion or formed integrally therewith. Sonach is preferably drilled from below the building ceiling through the shutter box into the building ceiling, so that a hole or a recess is created, which leads through the shutter box in the building ceiling. In this recess or hole in the building ceiling, the anchoring portion can be introduced and anchored therein. Subsequently, the connecting portion can be connected to the anchoring portion. Of course, it is also possible first to connect the anchoring portion and the connecting portion together and then introduce the anchoring portion in the recess in the building ceiling and anchor it there. All other possible combinations with the connection of the connecting portion with the mounting portion and the connection of the mounting portion with the window frame have been described previously or arise by appropriate combination of the individual steps.

In particular, in the method according to the invention with regard to buildings with existing building ceiling can be provided that in the building ceiling of the building a recess or a bore is produced, in which the anchoring portion is introduced and anchored, in particular glued, or in which a dowel is introduced with which the anchoring portion is connected, so that the dowel in the Recess braced. It is thus possible to form the anchoring portion and the connecting portion in one piece, so that it can be introduced, for example in the form of a tube in the recess and can be glued there by means of a suitable fastening means. Alternatively, it is possible to introduce into the recess of a building ceiling a dowel, which is connected for example with an anchoring portion designed as a threaded rod. By introducing the anchoring portion in the dowel this braced with the building ceiling and can then be connected to the connecting portion or be made in one piece with this.

Of course, all the features of the structure according to the invention, the fastener according to the invention and the method according to the invention are arbitrarily combinable or arbitrarily transferable or mutually applicable.

Fig. 1 shows a fastener 1 for the attachment of a window frame 2 to a building ceiling 3 of a building 4, see also Figures 2 . 3 , The fastening element 1 has a fastening section 5 for connecting the fastening element 1 to the window frame 2, an anchoring section 6 for anchoring the fastening element 1 in the building ceiling 3 of the building 4 and a connecting section 7 connecting the fastening section 5 to the anchoring section 6.

According to this embodiment, the fixing portion 5 is formed as a fixing plate. This is releasably attached to the connecting portion 7, for example screwed. The connecting portion 7 connects the attachment portion 5 with the anchoring portion 6. The length of the connecting portion 7 is at the height of a roller shutter box 12 (see. Fig. 2 ) or a shutter box (see. Fig. 3 ) customized. The connecting portion 7 is fixed by means of a fastening means 8 to the anchoring portion 6, for example screwed.

In this case, the anchoring section 6 is angled in its region facing the connecting section 7, for example at right angles, and has a Y-shaped cross-section in its region facing away from the connecting section 7. In particular, the anchoring section 6 can be formed from a sheet which is angled in the lower region, ie the region facing the connecting section 7, and in the opposite region, the region 9 which has the Y-shaped cross section, approximately in half along the longitudinal axis the anchoring portion 6 separated and bent up to a Y-shaped cross-section. The anchoring section 6 has in particular in the region of the Y-shaped cross section 9 holes 10, which serve the better anchoring or clawing in situ concrete. The installed state of the fastener 1 in the structure 4 is in Fig. 2 shown.

Fig. 2 shows a cross section through the structure 4, in particular in the region of a window 11 and the roller shutter box 12, which is arranged above the window 11. The fastening element 1 is screwed in this embodiment with the attachment portion 5 against the window frame 2 of the window 11. The attachment portion 5 abuts the underside of the roller shutter box 12 and is connected in the building inside facing part of the roller shutter box 12 behind the rolling room of the shutter box 12 with the connecting portion 7 of the fastener 1. The connection of the fastening portion 5 to the connecting portion 7 is preferably detachable, so that, for example, access to the interior of the roller shutter box 12 can be provided if required.

The connection section 7 designed as a tube is in turn screwed to the anchoring section 6 on the side opposite the attachment section 5 by means of a fastening means 8, which is designed as a screw. The connecting portion 7 has, as shown, a threaded portion in which the fastening means 8 is screwed from the side of the anchoring portion 6 and fastening means 13 from the side of the fixing portion 5 in the connecting portion 7. In the in Fig. 2 illustrated situation, the anchoring portion 6 is about 5 cm from the edge of a Filigrandecke 14 spaced, which rests on an inside edge of the masonry of the structure 4 and thus on the roller shutter box 12. By the spacing of the connecting portion 7 from the edge of the Filigrandecke 14, it is possible to screw the anchoring portion 6 to the connecting portion 7 with the fastening means 8.

The in Fig. 2 shown state already shows the finished state of the building ceiling, in which the anchoring portion 6 is cast in situ concrete. The anchoring portion 6 is thus anchored or digested in the in-situ concrete and can thus ensure a stable connection. Forces acting on the window 11, such as a wind load, is thus transmitted through the window frame 2 in the mounting portion 5 and from there via the connecting portion 7 in the anchoring portion 6 and thus in the Building ceiling 3 of structure 4 passed. Furthermore, in Fig. 2 a reinforcing steel 15 shown, to which the anchoring portion 6 has been connected prior to pouring into in-situ concrete.

Fig. 3 shows the connecting element 1 in a building 16. The fastener 1 is analogous to that in Fig. 2 present installation situation with the attachment portion 5 connected to a window frame 17 of a window 18 or screwed. The connecting section 7 is detachably fastened to the fastening section 5 via the fastening means 13, and the anchoring section 6 is attached thereto by means of a fastening means 8 on the opposite side. The anchoring section 6 is, as described above, embedded in the in-situ concrete of the building ceiling 19 of the building 16. Unlike the in Fig. 2 illustrated situation, the connecting portion 7 passes through no shutter box 12, but a shutter box 20. It is in Fig. 3 shown how the slats of the blind are included in the shutter box 20. The connecting portion 7 passes through the shutter box 20 in an area facing the inside of the building. The distance from the outside of the blind box 20, in which the connecting portion 7 passes through the shutter box 20, depends on the dimensions of the mounting portion 5 and is largely arbitrary, as long as the mounting portion 7 is not the function of the shutter of the shutter box 20 and the rolling room in the Roller shutter box 12 (in Fig. 2 ).

In the embodiment, the in Fig. 3 is shown, it would also be possible to arrange the connecting portion 7 further in the direction of the window frame. The distance between the connecting portion 7 and the window frame 17 is largely arbitrary. The attachment portion 5, which therefore indicates the distance between the window frame 17 and the connecting portion 7, can thus be chosen arbitrarily.

Fig. 4 shows a fastener 21 according to a second embodiment. The fastener 21 also has a mounting portion 22, an anchoring portion 23 and a Attachment portion 22 with the anchoring portion 23 connecting connecting portion 24. The attachment portion 22 is in this case designed as a fastening plate, which is detachably connected via a fastening means 25 with the connecting portion 24. The anchoring portion 23 has an external thread 26 and is formed integrally with the connecting portion 24.

The fastener 21 is therefore particularly suitable to be installed in buildings with existing building ceiling.

Fig. 5 shows a cross section through a structure 27, in particular in the region of a window 28 having a window frame 29 which is disposed below a shutter box 30. Through the shutter box 30 and insulating material mounted therein performs a bore in which the connecting portion 24 of the fastener 21 is received. The connecting section 24 passes through the roller shutter box 30. In the building ceiling 31 of the structure 27 is a recess 32, for example in the form of a bore. In the recess 32, a dowel 33 is inserted for mounting the fastener 21. The anchoring portion 23, which is formed integrally with the connecting portion 24 has an external thread 26 and is inserted through the shutter box 30 in the recess 32 and screwed there via the external thread 26 with the dowel 33. As a result, the anchoring portion 23 is securely anchored in the dowel 33. By screwing the two elements, the dowel 33 spans and is thus clamped in the recess 32 in the building ceiling 31 of the building 27. The anchoring section 23 is therefore anchored in the building ceiling 31. At the lower portion of the connecting element 24 this is connected by means of a fastening means 25 with the mounting portion 22, which in turn is connected via a fastening means with the frame 29 of the window 28, in particular screwed. Thus, the connection between the fastener 25, such as a screw, and the mounting portion 22 is detachable, so that the inspection cover shown here can be opened.

Of course, it is also possible in this case to choose the distance between the connecting element 24 and window frame 29 arbitrarily, as long as the connecting portion 24 does not pass through the rolling room of the shutter box 30. It is also possible to arbitrarily combine all the embodiments shown. It should be noted that, in particular with regard to a new building or a building with existing building ceiling, a special embodiment may be preferred.
