Description

The invention relates to a system for installing a finished window or the like prefabricate wall elements according to the preamble of the protection claim. 1

Ready-made windows, also called monoblocks or double-glazed windows in the construction industry, enable an active, versatile interior design in a simple way. They usually consist of a peripheral frame, in which two glass panes are arranged parallel with distance from each other. This usually prefabricated in the factory "Monoblock" can be installed in a wall opening of a stud wall. With a stud wall is meant a built in the desired area of space framework of vertical and horizontal uprights or uprights elements on the outside in particular one or both sides plates, in particular lightweight panels in the form of plasterboard are preferably secured by screws. As is known, the uprights or uprights have a wide variety of profile cross sections on, such as B. U, C, M or Ω profile cross-sections and are also called stator profiles.

For mounting or installation of a finished window or the like wall elements in a wall opening of a stud wall studs are already formed with an opening provided for attaching the finished window, the opening is limited at least on both sides, preferably from all sides by stud profiles. Lightweight panels, in particular plasterboard panels, are then fastened to this built-up framework on the outside or on both sides, so that the plasterboard panels are connected to the column profiles as close as possible to their edges. In this way, stator walls can be constructed with one or more wall openings for the installation of prefabricated windows or similar wall elements.

Often, subsequently formed wall opening of the stud walls are carried out, in which the prefabricated window elements are used and fixed, wherein joint areas are covered to the outside by screens. As fastening means, in particular screws and sealants are used. Fasteners are for example in the DE 101 34 396 C1 described which shows a combination of screws and mounting clips.

These mounting systems work well when both the stud wall and the window member have exactly the dimensions that were determined for installation. Usually, the known stud walls have a thickness of 100 or 125 mm. As soon as the wall thickness of the stud wall deviates from this standard value, even with a very small deviation, the entire construction no longer becomes exact, since the fastening elements have to be bent in order to be able to mount the finished wall element in the wall opening. Exact conditions, however, do not occur in reality or practice straight, but must always be expected with more or less large tolerance deviations in the dimensions of the upright profile and the thickness of the plasterboard, which of course correspondingly very beneficial effect in the finished wall with the window can.

Deviations in the range of about +/- 2 to 7 mm can usually occur in the case of a stator wall designed for 100 mm thickness, with the effect that a custom-made ready-made window can no longer be fitted or installed properly in the stator wall. Committee would be the result. Another possibility, such as a new custom tailor-made manufacturing of a finished window, also does not provide a viable solution to the problem due to the high cost and time involved.

Also with this system is an adaptation to peculiarities of the stator wall, such. B. to the profile of the stud wall or individual plasterboard, not possible. The window frame is usually made of aluminum, which makes a subsequent processing and adjustment of the finished window element or the like wall element either impossible or much more difficult. In this case, either a new individual window element must be completed with a new frame, which, however, only requires a precise profile dimension of the wall opening, or the stud wall to be adapted to the finished element. This means that this system will only work well if it does not deviate from standard sizes, which is not possible in practice. However, tolerance compensation is not possible with this system, which means that the flexibility in planning and designing a room is considerably limited.

In connection with the attachment of Türzargen in wall openings, it is known ( EP 0 562 249 A2 ) to use tolerance-compensating devices to allow adaptation to tolerance differences or the like dimensional inaccuracies, including adjustable connection means are provided with a T-shaped Justierprofil of an L-shaped longitudinal web and a Z-shaped crosspiece, which are each provided with slots to a To allow compensation. These slots are directed with respect to each other with respect to the longitudinal web and crosspiece, wherein the longitudinal openings in the longitudinal web run parallel to the reveal and perpendicular to the wall surface and the slots in the transverse web perpendicular to the soffit and parallel to the wall surface.

The invention has for its object to provide a fastening system for inserting or installation of a finished window or the like finished wall elements so that finished windows or the like finished wall elements can be installed easily, easily and flexibly.

This object is achieved by a fastening system according to protection claim 1. Advantageous developments of the invention will become apparent from the features of the dependent claims.

The system according to the invention with and for the installation of a finished window or the like prefabricated wall elements in a wall opening of a stud wall, characterized in that it comprises at least one tolerance adjustable angle element for attaching the finished window to the stud wall. The stud walls are in this case formed essentially of horizontal and vertical stud profiles with which one or both sides attached plasterboard, wherein the plasterboard terminates with the edge of the stud profiles. It is advantageous that the stator walls are formed so that the wall opening for inserting the finished window at least on both sides, preferably circumferentially bounded by the uprights, from above and below by horizontal profiles and from the left and right, that is laterally, by vertical profiles. CW profiles are provided in particular as upright profiles. By way of example, stator walls constructed in this manner have, as standard, a stator wall thickness of 100 mm. However, the stator wall thicknesses often deviate from the standard value in practice due to tolerances. The tolerances arise in particular in horizontal assembly of the wall construction, so when consolidating the plasterboard on the framework. Also, processing-related material doubling of the framework and / or frequently necessary Anspachtelarbeiten can lead to deviations from the standard value of the stator wall. Surprisingly, it has been found that by using at least one tolerance-adjustable angle element for attaching or fixing the finished window element to the stud wall, the deviations of the stud wall thickness from its standard value can be easily compensated or compensated. It is possible according to an advantageous embodiment of the invention to compensate for a deviation of -4 mm to +7 mm. Thus, by the use of the angle element according to the invention a trouble-free, stable installation of the finished window in the wall opening of a stator wall with a stator wall thickness in particular in the range of 96 to 107 mm possible. It should be noted that the angle element according to the invention for attaching window elements even with a stud wall, which shows no wall thickness deviation and / or another standard stator wall thickness of z. B. of 125 or 150 mm, can be applied. There are also applications in other areas conceivable.

In a preferred embodiment of the invention, the angle element in the form of an L-profile, one leg of which is preferably fastened by means of a screw on the stator wall. This attachment to the stud wall takes place on the stud profile through the gypsum plaster boards. The second leg of the angle element is designed such that it can be fastened with respect to the central axis of the stator frame facing window frame in the x and / or y-direction adjustable on the window frame preferably by means of a screw connection. Due to the possibility of the x and / or y-direction adjustable attachment of the angle element to the window frame, the finished window element can be mounted tolerance adjustable. As a result, its installation is tuned stably and optimally to the stud wall thickness of the gypsum plasterboard, which have both one or no deviation from the standard stud wall.

According to the invention, the angle element in its second leg on an oblong hole, which is obliquely set or inclined to the outer edge of the second leg. Due to the oblique position of the elongated hole, the displacement of the angle element in the x and y direction and thus the tolerance compensation of the stator wall thickness, in particular the strength of the plasterboard is possible. Preferably, the adjustment or displacement is infinitely variable, whereby a fine tolerance adjustment is possible. The range of tolerance compensation can be varied by varying the sizes, such as length, orientation, inclination of the elongated hole. Various embodiments of the angle element with respect to its adjustable attachment to the window frame, in particular on the window frame are described and illustrated below.

Preferably, the angle elements are arranged only on one side of the finished window element, which is very advantageous in terms of acoustic and fire-protected properties. However, it is also possible for their two-sided arrangement.

In an alternative embodiment of the invention, the fastening system comprises at least one attachable to the window frame fastener, preferably made Metal, which has at its two ends tabs for receiving angle elements, wherein the angle element instead of the elongated hole in its second leg has at least one open and substantially limited by U-shaped grooves for positive and / or non-positive cooperation with the tabs.

Conveniently, the window frame contained in the system of a mineral product, in particular gypsum fiber, more specifically cellulose fiber mixed with gypsum dissolved. A gypsum fiber board can be relatively easily reshape, z. B. by cutting, whereby the window frame or a window frame from the window frames also subsequently optimally, individually and without much effort to the peculiarities of the stud wall is customizable. A further advantage of the invention is that, when multiple prefabricated windows are installed next to one another, the prefabricated windows with window frames or window frames can be fastened together from a mineral product by means of an adhesive connection. There are no known from the prior art additional interlinking profiles needed. The interlinking profiles have the disadvantage that an additional frame must be installed between the adjacent windows. In contrast, the finished windows according to the invention by the adhesive bond directly next to each other, d. H. be installed adjacent.

In the context of the invention, the window frame can also be made of aluminum, steel, or wood or wood-based materials.

In an advantageous embodiment of the invention, the glass plates or windows of the window are fastened by means of an adhesive connection to the window frame. This ensures a secure hold of the two plates on the window frame, and on the window frame of window frames. Another advantage is that the plates can be used with different glass thicknesses up to a maximum glass thickness of 15 mm. Also can have glass plates of different colors, patterns and, where appropriate, ornaments. It is also conceivable Glass plates to use plates of other transparent materials. As an adhesive bond may double-sided, preferably for aesthetic reasons transparent adhesive tape, adhesive or the like. Be used.

In the context of the invention, it is further provided that the system has at least one integrated in the window frame or attachable to the window frame mounting bracket, which has open to the outer sides of the finished window open and essentially limited by U-grooves for receiving the cover strips. Preferably, the mounting bracket is formed integrally in a window frame made of aluminum, steel or wood, while being designed for use with a window frame of a mineral product as a separate item in the form of an H-profile, preferably made of aluminum, that it by means of a Screw can be attached to the window frame.

Due to the frictional force between the seal molding and the web, the web sits firmly in the U-groove. It can be achieved by the depth of insertion an adapted to the adjustable L-angle element arrangement of the cover strip. Since the insertion of the web into the U-groove takes place continuously, a fine depth adjustment and thus precise, tolerance adjustable adjustment of the cover strip on the window frame of the prefabricated windows take place, which are installed in a wall opening of a stator wall, with no or no deviation from the standard stator wall thickness having.

In a preferred embodiment, the web at the top of two circumferential mutually arranged, protruding lips. The size of the lips is adapted to the size of the U-grooves so that a secure hold of the web is ensured in the U-grooves with a gasket molding. Preferably, the lips are formed parallel to the bottom of the U-groove, whereby the interaction is reinforced with the sealing molding. Other embodiments of the lips, for example in the form of hooks, pins or the like are also conceivable.

In an advantageous embodiment of the invention, the sealing molding is made of an elastic material, preferably made of sponge rubber. The application of the sponge rubber achieves acoustic decoupling of the trim strip from the glass element. Further, by the length, i. H. the surface of the blank of the foam rubber, these forces of interaction are controlled and adjusted. The larger the area, the smaller the force. It should be noted that the blank of the sponge rubber must be at least as large as the circumference of the groove area in which the web is inserted in order to ensure a stable system.

As is known, this is formed of vertical upright profiles with essentially U-, C- or W-shaped profile cross sections, in particular CW profiles according to DIN standard 18182, on the outside of which at least one plasterboard panel is fastened by screws. In the illustrated embodiment, two plasterboard 18 are arranged one above the other parallel to each other on both sides of the upright profile 2 and fastened with suitable screws 15 on the legs of the profile 2. On the right side of the Fig. 1 is a detail of a finished window 3 shown. Usually this is formed from a peripheral window frame, which is preferably formed of two parallel and two horizontal Fensterzargen in which or on which one or two glass sheets are arranged. In the illustrated embodiment, both sides of the window frame 4 each have a glass pane 5 attached to the window frame 4 of the finished window 3 by means of a suitable adhesive bond. In the Fig. 1 the vertically extending window frame 4 is shown, which is preferably made of a molded part of mineral material, in particular gypsum fiber.

At the in the Fig. 1 shown prefabricated windows can connect another unfinished prefabricated window or a lightweight wall. In this way, several finished windows or lightweight walls can be arranged side by side or one above the other. Also is one of double window elements and Leichbauwänden arbitrarily assembled arrangement in a row or over the wall height conceivable.

The attachment of the finished window 3 to the stator wall 1 by means of angle elements 6, one of which in the lower portion of Fig. 1 is shown in plan view. The angle element 6 in this case has the shape of an L-profile whose short leg 6a with a not in the Fig. 1 shown hole 14 is provided and is fastened by means of one or more screw (s) 15 on one side of the stator wall on the leg of the upright profile 2. This hole 14 is in the Fig. 2 shown. His second longer leg 6b is also attached to the window frame 4 by means of about a screw 16 and although tolerance adjustable, whereby a transition from the stud wall to the finished window and thus a stable attachment of the finished window element in the wall opening of the stud wall is reached. The tolerance adjustable attachment is in detail in the Fig. 3 shown and described.

The angle element 6 is enlarged in Fig. 2 shown. It is formed of a shorter leg 6a and a longer leg 6b, here in each case with the same thickness. The shorter leg 6a is provided with a bore 14 for receiving a not in Fig. 2 provided screw 15 is provided. The bore 14 is centered in this embodiment in relation to the height of the in Fig. 2 shown leg 6a and about 5 mm away from the outer edge of the shorter leg 6a. In the longer leg 6b to the outer edge of the leg 6b for the purpose of adjustability obliquely oblong hole 17 is formed. This in Fig. 2 illustrated angle member 6 is preferably made of aluminum and formed in it slot 17 is inclined in an exemplary practical embodiment at an angle of -15 ° to the outer edge of the longer leg 6b, 23.2 mm long and 6.5 mm wide, all These dimensions are not restrictive. Also other forms of training of the slot 17 are conceivable. For example, the slot can be formed from one another passing holes, whereby the slot can have a stepped profile. As a result of the training, a tolerance compensation stepwise respectively. Other sizes, such as length, width and inclination of the elongated hole are suitable adaptable to different applications.

Fig. 3 represents a horizontally and vertically extending at the corner window frame 4, on which an angle element 6 is fixed with its longer leg 6 b by means of a screw 16. In the longer leg 6b of the angle element, the obliquely placed slot 17 is formed, in which, in its middle position, the screw 16 is arranged. This attachment of the angle element 6 in the middle position of the elongated hole 17 corresponds in this embodiment, an attachment of the finished window 3 in a wall opening of a stator wall 1 of 101 mm thickness. With the vertical displacement of the angle element 6 along the elongated hole 17, the shorter leg 6a moves away or approaches the outer edge of the window frame 4, whereby the width of the finished window 3 provided for installation with the angle element 6 can be adjusted. When the angle element 6 at the lowest point of in Fig. 3 Dargstellten slot 17 is fixed by a screw 16 to the window frame 4, thereby the shorter leg 6a and consequently the finished window 3 in a wall opening of a stator wall 1 with a stator wall thickness of for example 107 mm are stable and easily attached. With each height adjustment of the attachment, the corresponding pillar wall thickness decreases until it reaches a stable attachment to a stud wall 1 of stud wall thickness of 96 mm at the highest point of the elongated hole 17. Due to the inclined design of the elongated hole 17, it is possible with the height adjustment of the angle element 6 to compensate for a stator wall of 100 mm thickness production-related deviations in a range of 96 mm to 107 mm. The height adjustment of the angle element 6 takes place in the embodiment of Fig. 3 due to the advantageous design of the elongated hole 17 continuously. As a result, an adjustment due to manufacturing or assembly-related errors or deviations in a very simple manner possible.

The part 10b of the angle is directed with a U-profile to the outer sides of the finished window, which forms a groove 9 for receiving the diaphragm strip 7, 8, which is inserted here from the outside into the groove.

The cover strips 7, 8 can be flat or raised, ie formed high. A sublime molding strip 7 is in the upper section of Fig. 1 and a flat formed molding strip 8 is in the lower portion of Fig. 1 shown. An enlarged view of the two trim strips 7, 8 is corresponding in the FIGS. 5a and 5b shown. Both embodiments essentially have flat cover strips 7.1, 8.1 and a web 7.2, 8.2 formed at right angles to this cover strip for insertion into the groove 9 of the fixing bracket 10 and for non-positive connection between the fixing bracket 10 and the cover strips 7, 8. At the ends of the webs 7.2, 8.2 lateral thickening or protruding lips are 7.3, 8.3 formed on both sides, wherein the end piece of the webs is formed pointy. Also in the groove 9 two lateral webs or lips 9.1 are formed on both sides of the horizontal walls. In the Fig. 1 is in each groove 9, a sealing molding 11, preferably a blank of sponge rubber, shown. This acts with the inserted into the groove 9 web 7.2, 8.2 due to the frictional forces between the two and also due to the contact with the webs 9.1 in the walls of the groove 9 together so that the web is stuck in the U-groove 9 after insertion , In the Fig. 1 the web 7.2, 8.2 is fully inserted into the groove 9. The web can be inserted at different depths in the groove 9, whereby an attachment of the cover strips 7, 8 can be adapted to the tolerance built-in finished solid. Since the insertion of the web into the U-groove here is infinitely, a fine depth adjustment and Consequently, a precise, tolerance adjustable adjustment of the cover strip to the frame of the finished window can be achieved. This also allows installation-related deviations can be compensated.

The cover strips 7.1, 8.1 with their legs 7.4, 8.4 are in Fig. 1 applied to the outside of the plasterboard and the glass plate and may further be secured by means of an adhesive connection, for example a self-adhesive PVC lip seal (7.4, 8.4), a decorative band or the like.

Laterally on the window frame 13, two screw channels 12 for receiving a screw 16 for fixing the angle element 6 are integrally mounted on the window frame 4.

In Fig. 7 a further embodiment of the angle element and a further embodiment of its attachment to the window frame is shown. This angle element 19 has the shape of an L-profile in the side view and is formed from two legs 19a and 19b. The leg 19a is provided with a bore 14 for receiving a not in Fig. 7 provided screw 15, by means of which it is fastened to one side of the stator wall on the leg of the stator profile 2. The bore 14 is centered in this embodiment in relation to the height of the in Fig. 7 formed leg 19a formed. The second leg 19b has in this embodiment on both sides open and substantially limited by U profiles grooves 19.1, forming the guides for the purpose of adjustment. The U-shaped groove 19.2 extends in this embodiment over approximately the entire width of the leg 19b of Fig. 7 , Furthermore, in Fig. 7 a fastener 20 is shown, which is fastened to the window frame 4. The fastener 20 has two holes 21 for receiving in Fig. 7 not shown screws and is formed such that it has at its two end portions tabs 20.1, which is to the middle part of the fastener 20 in the direction away from the window frame are slightly offset, so that the angle elements 19 can be plugged from both sides. The angle element 19 can be pushed at different depths on the tab 20.1, whereby a tolerance adaptation to the thickness of the stator wall can be made from both sides. The sliding of the angle element on the tab 20.1 takes place continuously, whereby a precise tolerance compensation and thus the transition from the stator to the finished window can be achieved. The angle element 19 can be held positively in its position by cooperation with the tab 20, which is designed such that it represents the counterpart to the groove 19.1 of the angle member 19. In this case, a corresponding plug-in fit can be provided, so that the angle element is held in the inserted position accordingly. In this case, the outer edges of the tab 20.1 and the inner surface of the groove 19.1 may be notched, for example, whereby the angle element 19 can be engaged in accordance with the tab. Other locking elements are suitable. Alternatively, the angle element 19 in its position on the tab 20.1 non-positively, preferably held by an adhesive bond between the inside of the groove 20.1 and the outer edges of the tab 20.1, for example with a quick adhesive, such as a superglue.
