Description

[0001] The present invention relates to a reveal frame for integration into a window or door opening in a building wall and for receiving a window or door, comprising an upper frame profile, a lower frame profile forming a base, and two side frame profiles. The invention further relates to a building, in particular a passive house, comprising at least one building wall into which a reveal frame according to the invention is integrated.

[0002] In current technology, reveal frames with cuboid frame profiles are frequently used to accommodate windows or doors in building walls. Often, additional reinforcement, such as steel reinforcement, is required to ensure sufficient stability of the reveal frame within the building wall and, consequently, of the windows or doors it holds. This is often a costly and expensive process. Furthermore, conventional reveal frames do not guarantee sufficient stability at the point of attachment to the building wall. It is also known that the use of reveal frames with cuboid frame profiles negatively impacts the thermal insulation of the building. In many cases, thermal bridge-free installation cannot be guaranteed because windows held by such reveal frames can only be positioned within the area of ​​the building walls.This negatively impacts the energy efficiency of buildings, such as passive houses. Furthermore, it also negatively affects the dew point of building walls, which can lead to disadvantages such as the risk of mold growth on windows or doors.

[0003] The present invention is based on the objective of overcoming the disadvantages described above from the prior art.

[0004] This problem is solved according to the invention by a reveal frame with the features of claim 1 and a building with the features of claim 14.

[0005] The advantage of the reveal frame according to the invention lies particularly in the fact that at least the two lateral frame profiles each have a first contact surface for contacting the building wall, in particular an end face of the building wall, and a second contact surface for contacting the building wall, in particular an outer face of the building wall, wherein the first contact surface forms a right angle with the second contact surface. Thus, at least the lateral frame profiles are essentially formed at a right angle. This allows the reveal frame to be arranged and connected to building walls from two sides. This increases the stability of the reveal frame in the building wall and simultaneously avoids the need for additional, costly steel reinforcement.Due to the special shape, especially of the side frame profiles, it is possible to drive fasteners, such as screws, dowels or the like, into the building wall from the two contact surfaces and thus to fasten the reveal frame particularly stably in a building wall.

[0006] Advantageously, the lower frame profile of the reveal frame according to the invention also has a first contact surface for contacting the building wall, in particular an end face of the building wall, and a second contact surface for contacting the building wall, in particular an outer face of the building wall, wherein the first contact surface forms a right angle with the second contact surface. Thus, the advantages of the side frame profiles mentioned above also apply to the lower frame profile.

[0007] In a particularly preferred embodiment of the reveal frame according to the invention, at least the two lateral frame profiles have a substantially L-shaped cross-section and each comprises a first profile section forming a first contact surface and a second profile section forming a second contact surface and a second section of the L-shape. Thus, the lateral frame profiles can be arranged within an insulation layer of an exterior wall of a building and connected to a building wall from two sides. When the reveal frame is installed, the first profile section can be brought into contact with an end face of a building wall and the second profile section with an outer surface of the building wall.Preferably, one outer surface of the side frame profiles is flush with an outer surface of the insulation layer, and one inner surface of the side frame profiles is flush with an inner surface of the building wall. In this way, the reveal frame, with a window or door installed within it, can be integrated into a building's exterior wall without thermal bridges, thus improving the energy efficiency of buildings.

[0008] Advantageously, in the reveal frame according to the invention, the contact surfaces of the side frame profiles and / or the lower frame profile can have different widths. This allows the reveal frame to be individually adapted to the statics of building walls, thereby further improving the stability of the reveal.

[0009] Advantageously, the lateral frame profiles of the reveal frame according to the invention are identical. This enables simple and cost-effective production of a reveal frame, since a maximum of three different frame profiles need to be manufactured.

[0010] Advantageously, in the reveal frame according to the invention, the frame profiles are connected to a building wall by means of force-fit fasteners, in particular dowels and / or screws, and / or adhesive, in particular construction adhesive. This ensures a particularly strong and stable connection between the reveal frame and a building wall.

[0011] Advantageously, in the reveal frame according to the invention, the frame profiles are made of plastic, in particular pressed polystyrene. This results in robust and durable frame profiles that exhibit particularly good insulation values.

[0012] Advantageously, the respective frame profiles of the reveal frame according to the invention are designed in two parts, and both parts of the respective frame profiles are connected to each other by means of screws and / or adhesive. In this way, the lateral frame profiles, which preferably have a substantially L-shaped cross-section, can be manufactured particularly easily and quickly. According to the invention, it is also conceivable to integrate a first set of frame profile parts, preferably comprising a first part of the upper frame profile, the lower frame profile, and the two lateral frame profiles, into a building wall at the site of the construction of prefabricated houses, and thus to industrially prefabricate a building wall, for example, the wall of a passive house, with elements of a reveal frame.The prefabricated building walls then only need to be transported to a construction site and completed by a second set of frame profile parts, preferably comprising a second part each of the upper frame profile, the lower frame profile and the two side frame profiles.

[0013] However, the frame profiles can also be made from a single piece. This also applies to the complete reveal frame, which can then be integrated as a whole into a corresponding recess.

[0014] In a preferred embodiment of the reveal frame according to the invention, the upper frame profile has a device for at least partially concealing a window or door opening, wherein the device for at least partially concealing a window or door opening is preferably a roller shutter or a venetian blind, and wherein the upper frame profile is preferably designed as a roller shutter box or venetian blind box. In such an embodiment, it is no longer necessary, for example, to subsequently mount a roller shutter box on a window or door reveal.

[0015] For serial renovation, the complete reveal frame is prefabricated in series, so that when renovating a building, it only needs to be inserted into a corresponding recess in a building wall. Advantageously, the prefabricated reveal frame includes a roller shutter box with a roller shutter.

[0016] Advantageously, the upper frame profile of the reveal frame according to the invention is connected at its end regions to one end face of each of the first profile sections of the lateral frame profiles. Thus, the upper frame profile can essentially be arranged on and connected to the lateral frame profiles. This simplifies the construction of the reveal frame.

[0017] Advantageously, an insulating wedge is assigned to the upper frame profile of the reveal frame according to the invention, which is preferably bonded to the upper frame profile by means of adhesive. Thus, the upper frame profile, which may be designed, for example, as a roller shutter box or external venetian blind box, can be easily insulated in order to improve the overall insulation performance of the reveal frame and to ensure that the reveal frame is free of thermal bridges.

[0018] Advantageously, the upper frame profile of the reveal frame according to the invention is connected to a building wall, particularly a concrete ceiling, by means of a connecting element, in particular by means of a stiffening steel. This ensures a rigid and stable integration of the reveal frame into building walls and improved load distribution within an exterior wall of a building.

[0019] The present invention further relates to a building, in particular a passive house, comprising at least one building wall, in particular a concrete wall, which has a thermal insulation layer for thermal insulation and a recess for receiving a reveal frame for receiving a window or door, wherein a reveal frame according to the invention is received in the recess. Thus, the aforementioned advantages also apply to the building according to the invention. The preferred embodiments of the reveal frame according to the invention are also intended to apply to the building according to the invention.

[0020] Advantageously, in the building according to the invention, a window can be installed in the area of ​​the thermal insulation layer of the reveal frame, preferably in the area of ​​the dew point of the building wall. This allows energy costs for buildings, especially passive houses, to be reduced, and the risk of mold growth due to condensation on windows or doors to be minimized.

[0021] Further features of the invention will become apparent from the following description of preferred embodiments of the invention in conjunction with the drawings and the dependent claims. The individual features can be implemented individually or in combination with one another.

[0022] The drawings show: Fig. 1 a perspective view of a jamb frame according to the invention; Fig. 2 a front view of the reveal frame according to the invention Fig. 1 in its installed state in an outer wall of a building according to the invention; Fig. 3 a top view of the reveal frame according to the invention Fig. 1 in its installed state in an outer wall of a building according to the invention; Fig. 4 a side view of a further embodiment of the reveal frame according to the invention in the installed state in an outer wall of a building according to the invention.

[0023] Identical elements or elements with the same function are subsequently marked with the same reference numbers.

[0024] Fig. Figure 1 shows a perspective view of a reveal frame 1 according to the invention. The reveal frame 1 comprises two identically designed lateral frame profiles 6a, 6b, a lower frame profile 5 forming a base, and an upper frame profile 4. The frame profiles 4, 5, 6a, and 6b are made of pressed polystyrene and bonded together with adhesive. Each of the two lateral frame profiles 6a, 6b has a first contact surface 7a, 7b, with which an end face 8 of a building wall 2 can be contacted, and a second contact surface 9a, 9b, with which an outer surface 10 of a building wall 2 can be contacted. The first contact surface 7a, 7b forms a right angle with the second contact surface 9a, 9b.The lower frame profile 5 also has a first contact surface 7c, with which an end face 8 of a building wall 2 can be contacted, and a second contact surface 9c, with which an outer surface 10 of a building wall 2 can be contacted. The lower frame profile 5 is arranged between the side frame profiles 6a, 6b.

[0025] The lateral frame profiles 6a, 6b have a substantially L-shaped cross-section, with a first profile section 11a, 11b forming the first contact surface 7a, 7b and a second profile section 12a, 12b forming the second contact surface 9a, 9b. The upper frame profile 4 is arranged substantially between the lateral frame profiles 6a, 6b and its end regions 17a, 17b are positioned on and connected to the end faces 18a, 18b of the first profile sections 11a, 11b of the lateral frame profiles 6a, 6b. An upper side surface 24 of the upper frame profile 4 is flush with an end face 25a, 25b of the respective second profile section 12a, 12b of the lateral frame profiles 6a, 6b. The reveal frame 1 can thus be precisely integrated into a recess 23 of building walls 2 of buildings 100, as is the case, for example, in Fig. Figure 3 can be seen. Furthermore, this avoids thermal bridges in this area. In this way, the thermal bridge-free reveal frames 1 according to the invention are also suitable for retrofitting existing buildings.

[0026] Fig. Figure 2 shows a front view of the reveal frame 1 according to the invention. Fig. 1 in the installed state in a building wall 2 of a building 100 according to the invention. The reveal frame 1 comprises the frame profiles 4, 5, 6a and 6b and is bonded to a building wall 2, wherein the two side frame profiles 6a, 6b and the lower frame profile 5 are additionally secured by means of dowels 15, as is the case, for example, in Fig. 3 or Fig. As can be seen in Figure 4, the second contact surfaces 9a, 9b of the side frame profiles 6a, 6b, and the second contact surface 9c of the lower frame profile 5 are connected to an outer surface 10 of the building wall 2 of building 100. It is clearly visible that the second profile sections 12a, 12b of the side frame profiles 6a, 6b are connected to the building wall 2 outside the recess 23. Here, the lower frame profile 5 also has a second profile section 12c, which has the second contact surface 9c, as well as a first profile section 11c, which has the first contact surface 7c (not shown). The second profile section 12c of the lower frame profile 5 is also connected to the building wall 2 outside the recess 23. Thus, the reveal frame 1 is connected to the building wall 2 of building 100 in a particularly stable manner.A window 3 is mounted in the reveal frame 1 and additionally connected to a support element 14 arranged on the upper side 13 of the lower frame profile 5. This ensures a particularly stable mounting of the window 3 in the reveal frame 1.

[0027] Fig. Figure 3 shows a top view of the reveal frame 1 according to the invention. Fig. 1 in its installed state in a building wall 2 of a building 100 according to the invention. The building wall 2 forms an outer wall of the building 100 and has an insulating layer 22 made of Styrodur on its outer surface 10. ®The reveal frame 1 is integrated into a recess 23 in the building wall 2. The first contact surfaces 7a, 7b of the lateral frame profiles 6a, 6b each contact end faces 8 of the building wall 2, and the second contact surfaces 9a, 9b each contact outer surfaces 10 of the building wall 2. It is particularly evident here that the lateral frame profiles 6a, 6b are connected to the building wall 2 at a right angle by means of dowels 15, with the respective first contact surfaces 7a, 7b forming a right angle α with the respective second contact surfaces 9a, 9b. A first dowel 15 is driven perpendicular to and from the first contact surfaces 7a, 7b through the respective end face 8 of the building wall 2 to create a first connection between the respective lateral frame profile 6a, 6b and the building wall 2.A second dowel 15 is driven perpendicularly to and from the second contact surfaces 9a, 9b into the respective outer surface 10 of the building wall 2 to create a second connection between the respective lateral frame profile 6a, 6b and the building wall 2. This allows the reveal frame 1 to be connected to the building wall 2 in a particularly stable manner. The width b of the first contact surfaces 7a, 7b of the lateral frame profiles 6a, 6b corresponds to the width b' of the second contact surfaces 9a, 9b of the lateral frame profiles 6a, 6b. The upper frame profile 4 is connected at its end regions 17a, 17b to one end face 18a, 18b of each of the first profile sections 11a, 11b of the lateral frame profiles 6a, 6b. A first outer surface 28a, 28b of the lateral frame profiles 6a, 6b is flush with an outer surface 26 of the insulation layer 22, while an inner surface 29a, 29b of the lateral frame profiles 6a, 6b is flush with an inner surface 27 of the building wall 2.An outer surface 30 of the upper frame profile 4 is also flush with the outer surface 26 of the insulation layer 22. Outer surfaces 33a, 33b of the second profile sections 12a, 12b of the side frame profiles 6a, 6b each contact an end face 34 of the insulation layer 22. In this way, improved insulation of the building wall 2 of the building 100 can be ensured. A window 3 is mounted in the area of ​​the insulation layer 22 by the reveal frame 1. Thus, the dew point T of the building wall 2 is located in the area of ​​the insulation layer 22, thereby reducing the risk of mold growth on the window 3 due to condensation.

[0028] Fig.Figure 4 shows a side view of another embodiment of a reveal frame 1' according to the invention in its installed state in a building wall 2 of a building 100 according to the invention. The reveal frame 1' is integrated into a recess 23 of the building 100. A window 3 is accommodated by the reveal frame 1'. An upper frame profile 4' is designed as a roller shutter box and includes a roller shutter 16. Thus, it is no longer necessary to retrofit a roller shutter 16 for the window 3. An insulating wedge 19 is associated with the upper frame profile 4' and is bonded to it. The upper frame profile 4' and the window 3 are connected to a building ceiling 32 of the building 100 via stiffening steel 20 and are additionally bonded to it. In this way, a rigid and stable integration of the reveal frame 1' and improved load distribution in the building 100 are ensured.

[0029] Furthermore, it is clearly visible that the first contact surface 7c of the lower frame profile 5 contacts an end face 8 of the building wall 2, and that the second contact surface 9c of the lower frame profile 5 contacts an outer surface 10 of the building wall 2. The two contact surfaces 7c and 9c form a right angle α. The lower frame profile 5 is connected to the building wall 2 by means of dowels 15. A first dowel 15 is driven perpendicular to and from the first contact surface 7c through the end face 8 of the building wall 2 to create a first connection between the lower frame profile 5 and the building wall 2. A second dowel 15 is driven perpendicular to and from the second contact surface 9c into the outer surface 10 of the building wall 2 to create a second connection between the lower frame profile 5 and the building wall 2.The two dowels, like the first contact surface 7c and the second contact surface 9c of the lower frame profile 5 in the present embodiment, are also positioned approximately at right angles to each other. This allows the reveal frame 1' to be connected to the building wall 2 with particular stability. The width b of the first contact surface 7c differs from the width b' of the second contact surface 9c of the lower frame profile 5. An outer surface 31 of the lower frame profile 5 is flush with an outer surface 26 of the insulation layer 22. Similarly, an outer surface 30 of the upper frame profile 4' is flush with the outer surface 26 of the insulation layer 22. An outer surface 33c of the lower frame profile 5 contacts an end face 34 of the insulation layer 22. Therefore, the reveal frame 1' is arranged flush with the insulation layer 22 of the building wall 2. This prevents thermal bridges in the area of ​​the recess 23 of the building 100.
