Description

Technical area

The invention relates to a frame arrangement, in particular for closing a building opening, with a frame defining a frame plane, in particular a window or door frame. The frame is constructed from hollow frame profiles which each have at least one main chamber, an inner prechamber and an outer prechamber, adjacent chambers being separated from one another by partitions extending substantially parallel to the frame plane. The frame assembly further comprises a substantially plate-shaped frame attachment part, which is fastened to the frame such that the frame is arranged with an outer edge side in gegeneinanderstossender arrangement with respect to a opposite side of the frame connection part and that a plate plane of the frame connection part is aligned parallel to the frame plane. The frame assembly further comprises a connection device for fastening the frame attachment part to the frame, comprising a support part for arrangement on an edge side of the frame attachment part opposite the frame in a connected state, such that the support part is supported on the edge side, and a connection means with a profiled section. The invention further relates to a method for fastening a substantially plate-shaped frame connection part to a frame constructed from hollow frame profiles, each having an inner prechamber and an outer prechamber.

State of the art

It is known to form the frame of a window, a door or similar Gebäudeöffnungsabschlusses with much smaller outer peripheral masses than the light mass of the building opening (also called Mauerlichtöffnung, window or Türaussparung), in which the frame is to be used. In the space between the frame and the inner edge sides of the building opening, then plate-shaped frame connection parts are arranged. These frame attachment parts (frame widenings, window frame duplications) can be arranged on only one frame side (eg above), on several sides of the frame or also on all frame sides, so that they form a frame surround as a whole. The frame connection parts have the function of fastening elements, which fasten the frame in the building opening, on the one hand, and the function of closing elements, which tightly close the building opening between the frame and the building opening edge, on the other hand.

Window and door frames are often made of hollow profiles made of plastic or metal (eg aluminum). For a good thermal insulation can be achieved, the hollow sections between their outer state in the installed state and in its inner state in the installed state boundary several partitions parallel to the frame plane, so that a plurality of mutually closed chambers are formed in the hollow profile. Hollow profiles are known, for example, with a main chamber which is surrounded by two prechambers. In the case of plastic profiles, a metal frame reinforcement extending parallel to the frame plane is often arranged to improve the mechanical stability in the main chamber.

For the connection of the frame connection part with the hollow profile frame, various possibilities are known. Conventionally, with the aid of a drilling jig, a hole is drilled through the frame (and thus possibly also through the frame reinforcement) through the frame inside the frame side facing away from the frame connection part into a core plate of the frame connection part. Thereafter, a screw is screwed into this hole until the screw head rests on the inside of the frame and a tensile connection between the frame and the frame connection part is created. Often the Screw head for aesthetic reasons and to avoid injury from sharp edges covered by a cap.

For the screw to be held in the frame connector, the core plate must have a certain mechanical strength. To ensure this, it is made, for example, from a polyurethane foam (Puren), while they are made of lighter polystyrene foam (EPS) surrounding insulation plates, which have no attachment function. Thus, the created by the hole through the frame through the cold bridge does not lead to a significant impairment of the thermal insulation capacity of the frame assembly, also between the frame and the core plate insulation is introduced, for. B. by means of a Kompribands surrounding the bore. The attachment of the frame connection part to the building opening is effected, for example, by a wall anchor, which is likewise secured in the core plate of the frame connection part by means of a second screw.

However, this known fastening has a number of disadvantages: The core plate required for fastening purposes in the frame connection part leads to a high weight of the frame connection part and impairs the achieved insulation values; mounting the frame widening is cumbersome, especially if a metal frame reinforcement in the main chamber is to be pierced; the insulation of the frame is reduced despite the additional insulation between frame and connector, and the screw head (or cover) visible on the inside of the frame affects the aesthetics of the frame assembly.

To address some of these disadvantages, other solutions have been proposed. The EP 1 191 180 A1 (Kurt Steineberg GmbH) shows a connecting device comprising projection-like connecting means, which are attached to the frame or the connecting part and which cooperate with grooves on the opposite part. This avoids the need to pierce the frame. However, this device requires certain structural features (in particular suitable grooves) on the frame and / or on the connecting part. The connection part must also absorb or transmit tensile forces for fastening the frame in the building opening, so that its Construction can not be optimized for optimal thermal insulation in consideration of mechanical requirements.

The EP 1 457 635 A1 (Kurt Steineberg GmbH) discloses a frame arrangement in which the frame connection part is held on the frame by means of an anchoring device which can be inserted into a groove, a threaded rod which can be attached thereto and a counterpart which can in turn be fastened thereto. The connecting device thus formed extends from the frame peripheral side to the building opening edge side and thus provides a high-tensile connection between the frame and the building opening edge. The connection part therefore no longer has to absorb or transmit tensile forces, so that its design can be aligned with optimum thermal insulation.

However, even with this frame assembly, the mounting of the connection part on the frame is quite complex, and also here certain structural features (grooves) are provided on the frame.

Presentation of the invention

The object of the invention is to provide a frame assembly belonging to the technical field mentioned above, which can be realized with a large number of frames and which can be produced quickly and easily.

The solution of the problem is defined by the features of claim 1. According to the invention, in the connected state, the connecting means extends from the support part through the frame connection part into one of the antechambers of the frame, and the profiled section is held on the front and / or intermediate walls of the pre-chamber such that a direct, high-tensile connection between the frame and the support part is created.

The connecting means is in particular straight and substantially rod-shaped. In the comparatively narrow prechamber it is securely held with its profiled section. In order to achieve the best possible hold, a connecting means is advantageously chosen whose cross section is adapted to the dimensions of the prechamber. That's how it works Connecting means cooperate not only with end and intermediate walls transverse to the main direction of the connecting means, but also with side walls which are approximately parallel to the connecting means. Because in the antechambers of plastic frame usually no metal reinforcements are performed, the connection means can also attach easily in the frame, without metal would have to be drilled. The frame does not need to have grooves so that the connection means can be attached to the frame. The frame connection part does not have to absorb or transmit tensile forces and can thus be optimized with regard to thermal insulation. The seal between the connection part and the frame can be made directly by the insulation material of the connection part, an additional seal or the profiling of the insulation material is unnecessary. A good tightness can be achieved in a simple manner with the help of a introduced between the insulating material and the frame Compriband or a sealing cord.

Because in the inventive frame assembly no screwing from the inside is necessary, a window can be finished fabricated, it is not necessary for the installation of the frame widening to open the casement. By screwing the frame widening from the outside into the frame results in an above-average stability. The break point between frame and frame broadening is improved.

• a) zunächst der Rahmen mit einer Aussenrandseite in gegeneinanderstossender Anordnung bezüglich einer Gegenseite des Rahmenanschlussteils angeordnet wird, so dass eine Plattenebene des Rahmenanschlussteils parallel zur Rahmenebene ausgerichtet ist;
• b) anschliessend das Abstützteil auf eine dem Rahmen gegenüberliegende Randseite des Rahmenanschlussteils aufgesetzt wird; und
• c) das Verbindungsmittel vom Abstützteil durch das Rahmenanschlussteil hindurch in den Rahmen hindurchgeführt wird, bis der profilierte Abschnitt des Verbindungsmittels in eine der Vorkammern eindringt und mit Begrenzungs- und/oder Zwischenwänden der Vorkammer derart zusammenwirkt, dass eine direkte zugfeste Verbindung zwischen dem Rahmen und dem Abstützteil geschaffen wird.

The connection between the connection part and the frame can be made quickly and easily by

• a) first the frame is arranged with an outer edge side in gegeneinanderstossender arrangement with respect to a opposite side of the frame connection part, so that a plate plane of the frame connection part is aligned parallel to the frame plane;
• b) then the support member is placed on a frame opposite the edge side of the frame connection part; and
• c) the connecting means is passed from the support member through the frame connection part into the frame until the profiled portion of the connection means penetrates into one of the antechambers and with boundary and / or partitions of Vorkammer cooperates such that a direct tensile connection between the frame and the support member is created.

The placement of the support member and the passage of the connecting means can be carried out successively or simultaneously. For example, the support part may already be arranged at the beginning of the fastening process in the region of the rear ends of the connecting means, so that a drilling jig can be arranged between the support part and the front end connecting means, which ensures that the connecting means are guided along a predetermined path through the frame and which possibly also the connection part centered on the frame.

The profiling of the connecting means is designed in such a way that the connecting means can be easily (eg by means of a sliding or a screwing movement) introduced into the pre-chamber, but that it can then be retracted again only with great effort. This can be achieved, for example, by an asymmetric (eg undercut) profiling. But particularly preferred is the formation of the profiled section as a threaded portion. The connecting means is thus a (possibly pointed) threaded rod or a screw, z. As a so-called chipboard screw, the thread does not have to run along the entire shaft. Thus, it is possible that the connecting means without pre-drilling through the frame connection part and is screwed into the frame. The screw thread drilled in this process through the frame connection part and (at least partially) through the boundary and / or intermediate walls of the antechamber and is then held tensile strength on these walls. It has been shown that this process works well in both plastic and metal frames. In special cases, d. H. For special geometries or material combinations, a pilot hole in the frame connection part and possibly also in the frame can be made, especially if the screw is to be additionally guided during subsequent screwing.

As part of a particularly advantageous variant of the inventive frame assembly, a connecting means is used whose length is adjustable, so that it can be easily adapted to different width frame extensions and / or to different frame geometries and / or profiles. Such a connection means includes, for example, a first, front portion with an external thread and a second, rear portion, with an internal thread, which can cooperate with the external thread of the first portion to form a tension-resistant connection. The rear portion includes a head for support on the support member or other attachment for the support member. To adjust the length of the rear section is screwed more or less on the front section. The front portion can be formed, for example, by a commercially available chipboard screw of suitable length, the head has been cut off.

In the connected state, the connecting means advantageously forms an acute angle with the plane of the plate. The straight and substantially rod-shaped connecting means thus occurs in a fixed position at a first point in the frame connection part, extends obliquely within the same and at a second point in the frame, wherein the two points a different distance to the outer surface of the connecting part or the Have frame. In particular, the second point is positioned farther outward (i.e., closer to the outer surface) than the first point, i. H. the connecting means extends starting from the connecting part in the direction of the frame obliquely outwards. The angle between the connecting means and the plane of the plate need not be large, depending on the length of the connecting means and the extent of the antechamber are usually enough already 1-2 °. But there are also larger angles up to the range of 5-10 °, with connection parts of small width also up to 10 ° or even 20 °, possible.

In principle, it is also possible to guide the connecting means parallel to the plate plane. Due to the oblique arrangement of the connecting means but there is a better anchoring of the profiled section in the antechamber.

When conventional connection elements and conventional frames are used, guidance of the connection means obliquely outwards further simplifies the production of the connection: Conventional connection elements are constructed in sandwich construction and have a comparatively soft insulation plate of a heat-insulating material (eg Polystyrene foam EPS), which is completed on both sides of relatively hard cover plates and connected to these. The two cover plates and the insulation plate are each with their main planes parallel to the plate plane oriented the frame connector. In conventional hollow frame profiles, the inner pre-chamber adjoins a first boundary of the frame hollow profile parallel to the frame plane, and the outer pre-chamber adjoins a second boundary of the frame hollow profile opposite the first boundary parallel to the frame plane. If now the connecting means, starting from the supporting part, is guided slightly obliquely outwards into the frame connecting part (it is not necessary that a precisely predetermined angle must be maintained), after a certain distance the tip of the connecting means contacts the corresponding lateral cover plate of the connecting part; then the connecting means is automatically guided by this to the frame. There, the connecting means enters reliably into the antechamber, which is completed by the running in the plane of the cover plate boundary of the frame profile. Thus, drilling or guiding gauges are unnecessary.

The fastening process is additionally facilitated if the hollow frame profiles each have on their outer edge side in the region of the antechambers a groove running parallel to the frame surface. Such grooves are common in many of the known frame profiles and are normally used as part of a clip system for attachment of auxiliary profiles. Such auxiliary profiles are used to slightly widen the frame. In the context of the present invention, this task is usually taken over by the frame connection parts. However, it has surprisingly been found that the grooves during screwing or insertion of the connecting means act as guides, as it were, which precisely introduce the tip of the connecting means in the antechambers. With a suitable dimensioning of the connecting means (eg when using a screw with a suitable diameter), the grooves also lead to an increased tensile strength, because the profiled portion of the connecting means on the walls and / or the inwardly projecting portions of the groove opening bounding the Groove is held in addition.

In a particularly preferred embodiment of the invention, the connecting means is guided through a through hole in the supporting part and is supported on the supporting part in the connected state of the frame arrangement by means of a head or another supporting element (eg a nut or a plug pin). In this way, the tensile connection can be realized in a very simple manner.

Alternatively, the connection means is fastened to the support part in another way (eg by frictional engagement or by means of gluing), or the connection means and the support part are made in one piece.

Two connecting means may be disposed in a single plane transverse to the frame plane, with a first one of the connecting means extending into the inner prechamber and a second one of the connecting means extending into the outer prechamber. As a result, a particularly stable attachment of the frame connection part is achieved on the frame. It also takes place during manufacture of the attachment automatically centering of the connection part on the frame.

Alternatively, the connecting means are arranged, for example, along the longitudinal extent of the frame or of the connecting piece such that they extend alternately into the inner and the outer prechamber.

The support member may be formed by a fastening device for fixing the frame assembly in a building opening, for. B. by a wall anchor or a ceiling mounting element. This has the advantage that, as part of the attachment of the frame connection part on the frame at the same time the fastening device is attached tensile strength on the frame connection part. Additional screws are unnecessary, thereby reducing the price and the weight of the frame assembly.

In a frame assembly a plurality of support members and fastening devices are usually required. Depending on the required numbers, all supporting parts or only some of them can simultaneously serve as fastening devices, or the fastening devices are basically mounted separately from the supporting parts on the frame connecting part.

The fastening device (wall anchor) can also be provided in addition to a supporting part. However, a wall anchor can still be attached to the connecting means, for. B. by means of screws which are screwed into the rear end faces of the connecting means.

In an advantageous variant of the inventive frame arrangement, the support part is formed by an elongated strip of wood, plastic or metal. This runs parallel to the frame main plane and is narrower than the edge side of the frame connection part. The strip may be solid or a tube (eg with a rectangular cross-section). With sufficient strength, the strip exerts a uniform pressure on the frame connection part or its insulation plate. It is thus possible to achieve a stable attachment of the frame connection part to the frame with a smaller number of connection means. A fastening device, such. As a wall anchor, can be attached to the bar in a conventional manner. Along the outer edge side, a continuous bar can be used, or several strip-like sections are used one behind the other.

If the frame connection part is fastened to the frame by means of two connection means arranged in the same plane extending transversely to the plane of the frame, two strips arranged next to one another and running parallel to one another and mechanically connected to one another are advantageously used. If these strips are formed of metal, the connection is advantageously carried out by a chrome steel profile, so that the formation of a cold bridge is avoided.

A frame arrangement according to the invention can also comprise a plurality of frames constructed from hollow profiles, wherein two adjacent frames arranged in the same frame plane are connected to one another via a frame connection element. In this case, one of the frames can form the supporting part, ie the connecting means is guided from the inner edge of this frame, starting through the frame and then through the connecting part, into an antechamber of the second frame. The connecting means can thus be guided in particular first through a through hole in the first frame and supported by means of a head or other support member on the first frame. For aesthetic reasons or to avoid injury from sharp edges, the head or the support element can be provided with a cover.

In general, the scope of the invention is not limited to end elements for building openings such as doors or windows. Frame arrangements according to the invention can be used wherever a frame is to be provided with a frame connection element (a frame widening), that is to say, for example. As in conservatories or pavilions in which entire walls or roof elements are constructed of several interconnected frame.

The frame connection part may comprise frame-side widening parts which extend parallel to the plate plane and project on both sides of the frame beyond the peripheral side of the frame facing the frame connection part. These parts can be formed, for example, by correspondingly extended sections of cover plates of the frame connection part. When connected, they partially overlap the frame parallel to the frame plane. This embodiment is aesthetically advantageous, allows a better insulation between the frame and connector and simplifies the attachment of the connector, because it already centered his protruding widening parts before making the connection to the frame.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

FIG. 1A shows a perspective partial view of a first embodiment of a frame arrangement according to the invention, and FIG. 1B is an enlarged view of the section marked by a circle in FIG. 1A. The frame assembly 100 includes a rectangular frame 110, e.g. Example, a window frame of a window, which is composed of hollow sections 111, and a frame connection part 140, which is held by means of a connecting device 150 on one of the hollow sections 111 of the frame 110.

The frame 110 is a conventional frame known per se. The hollow profile 111 made of PVC plastic forms several longitudinal along the frame boundary running chambers, namely an inner prechamber 112, a main chamber 113 and an outer prechamber 114. The inner prechamber 112 is on its inner, ie the built-frame to the building interior side facing directly completed by the inner wall 115 of the hollow section 111, the outer pre-chamber 114 is closed on its outer side by the outer wall 116 of the hollow section 111. Between the chambers vertical partitions 117, 118 are arranged. At their the frame opening or the frame peripheral side facing the ends of the chambers are through the corresponding resulting in a further improved thermal insulation and better mechanical stability of the frame 110. On the frame opening facing the frame side a stop 122 is arranged for the sash of the window. On the outer surface of the frame-periphery-side frame wall 120, profiles 123, 124 are arranged along the inner wall 115 and along the outer wall 116 of the hollow profile 111, which form grooves 125, 126 extending parallel to the frame boundary. These grooves 125, 126 are found on many commercially available plastic or metal frames and typically serve as part of a clip system for attaching auxiliary profiles (frame extensions).

The frame connector 140 is constructed in sandwich construction and includes a polystyrene foam (EPS) insulation panel 141 which is sealed on both the inside and outside by a plastic (e.g., PVC) cover plate 142, 143 bonded thereto is. The thickness of the insulation plate 141 of the frame connection part 140 corresponds to the thickness of the frame profile 111. The cover plates 142, 143 have frame-side widening parts 142 a, 143 a, which on both the inside and on the outside of the frame 110 on the peripheral side facing the frame connection part 140 Frame 110 out and partially overlap the frame 110 parallel to the frame plane in the connected state.

The connecting device 150 comprises plate-shaped supporting parts 151 which rest on the insulating plate 141 on the side of the frame connecting part 140 facing away from the frame. The length of a support member 151 substantially corresponds to the width of the insulation plate 141, its width about one third thereof. Each support member 151 has two perpendicular to its main surface oriented, through holes 151 a, 151 b. The distance between the holes 151 a, 151 b is slightly less than the distance of the vertical planes of symmetry of the antechambers 112, 114. The support members 151 are connected by tapered threaded rods 152, 153 with the hollow section 111 of the frame 110. For this purpose, the threaded rods 152, 153 are guided through the bores 151 a, 151 b of the support part 151, penetrate the insulation plate 141 of the frame connection part 140 and enter the respective prechamber 112 or 114, in which they are screwed. At the rear end of the threaded rods 152, 153 is a hex nut 154, 155 rotatably mounted. In attached State, this is supported on the outer surface of the support members 151 and thus creates a tensile connection between the frame connection part 140 and the frame 110th

Due to the smaller compared to the distance of the antechambers 112, 114 distance of the bores 151 a, 151 b include the threaded rods 152, 153 an acute angle of about 1.5 ° with the plane of symmetry of the frame connection part 140 and the frame 110 a. The screwing of the threaded rods 152, 153 in the pre-chambers 112, 114 takes place in the longitudinal grooves 125, 126, in the frame peripheral side facing frame wall 120, in the horizontal partitions 121 and partially on the inner wall 115 and the outer wall 116 of the hollow section 111th (In Figures 1A, 1B, a window is shown in the inner wall 115, this only serves to better visibility of the position of the threaded rod 153 and is not present in the real version.) The slightly oblique arrangement of the threaded rods 152, 153 results in a Centering of the frame connection part 140 on the frame 110, in addition, the attachment of the threaded rods 152, 153 in the hollow profile 110 is improved by enlarged contact surfaces between the threads of the threaded rods 152, 153 and the chambers and partitions of the hollow section 111.

On one of the illustrated support members 151, a wall anchor 156 is attached to secure the frame assembly 100 to a ceiling. For this purpose, the corresponding threaded rod 153 is first guided through a through opening 156a of the wall anchor 153 and only then through the opening 151 b of the support member 151. The wall anchor 156 is additionally connected directly to the insulation plate 141 of the frame connection part 140 by means of a screw 157 guided through a further opening 156b of the wall anchor, which primarily has the function of preventing rotation.

The fastening of the frame attachment part 140 to the frame 110 shown in FIGS. 1A, 1B is produced as follows. First, the frame connector 140 is pushed onto the frame 110. The frame-side widening parts 142a, 143a result in a precisely fitting centering of the frame connection part 140 on the hollow profile 111 of the frame 110. Next, the support parts 151 are placed on the frame 110 facing away from the outer surface of the frame connection part 140 and optionally the wall anchors 156 are arranged at the desired locations. Then, the threaded rods 152, 153 through the holes 151 a, 151 b, 156 a of the support member 151 and optionally the wall anchor 156 out and slightly obliquely screwed outwardly through the insulation plate 141 therethrough. A drilling jig is not necessary, so that approximately the correct direction is maintained, the holes 151 a, 151 b in the support member 151 may be slightly obliquely performed, but an attachment is not too large thickness or not too small hole diameter in the support 151 also possible with straight holes.

As soon as the tip of the threaded rod 152, 153 encounters the inside of the corresponding cover plate 142, 143 during the screwing operation, it is deflected in the direction of the hollow profile 111 in comparison with the insulation plate 141 because of the considerably greater hardness of the cover plate 142, 143. There, it is guided by the hollow profile 111 itself, or the profiles 123, 124 on the outer surface of the frame peripheral side frame wall 120 in the grooves 125, 126 into it. As soon as the threaded portion of the threaded rod 152, 153 enters the respective groove 125, 126, the actual screwing of the threaded rod 152, 153 in the frame 110 sets by the threaded portion initially in the groove opening limiting, inwardly projecting Sections of the groove 125, 126 and then into the horizontal end and intermediate walls 120, 121 of the respective prechamber 112, 114 screwed. With suitable dimensioning of the diameter of the threaded rods 152, 153, namely, if this is only slightly smaller than the width of the antechambers 112, 114, in addition, a fastening to the side walls of the groove 125, 126 and a support of the front end of the threaded rod 152, 153 on the inside of the inner or outer wall 115, 116 of the hollow profile 111th

FIG. 2 shows a cross section through a second embodiment of a frame arrangement according to the invention. The basic principle of the frame arrangement 200 corresponds to that of the first embodiment according to FIGS. 1A, 1B. In the following, we will therefore focus primarily on the differences from the first embodiment. The frame connector 240 has no protruding frame-side widening parts. The cover plates 242, 243 close in the fastened state flush with the inner wall 215 or to the outer wall 216 of the hollow profile 211. A precise centering of the frame connection part 240 on the frame 210 is achieved by the shape of the insulation plate 241 of the frame connection part 240. The insulating plate 241 has a central portion 241 a, which in the fastened state between the profiles 223, 224 engages on the outer surface of the frame peripheral side frame wall 220 in the manner of a tongue and groove connection, thus centering the frame connection part 240.

The bores 251 a, 251 b in the support part 251 are closer together in the second embodiment and thus further away from the planes of symmetry of the antechambers 212, 214 in the hollow profile 211. Accordingly, the angle between the threaded rods 252, 253 and the plane of symmetry of the frame connection part 240 and the frame 210 is larger and is about 3.5 °. The wall anchor is held by both threaded rods 252, 253 and the corresponding nuts 254, 255 on the support member 251 and thus on the frame connection part 240.

FIG. 3 shows a cross section through a third embodiment of a frame arrangement according to the invention, in which two frames are coupled together by means of a frame connection part and thus form a frame arrangement 300. The one frame 370 forms the supporting part in this configuration, while the other frame 310 is held on the frame fitting 340 by a threaded portion of a threaded rod 352, as in the first two embodiments.

The frame connection part 340 is in turn constructed in sandwich construction and comprises an insulation plate 341 of polystyrene foam (EPS), which is closed on both the inside and on the outside by a glued with her cover plate 342, 343 made of plastic. The thickness of the insulation plate 341 of the frame attachment part 340 corresponds to the thickness of the hollow profiles 311, 371 of the frames 310, 370. The cover plates 342, 343 have extension parts 342a, 343a on both sides; 342b, 343b, which both on the inside and on the outside of the frames 310, 370 protrude beyond the frame connection part 340 facing peripheral sides of the frame 310, 370 out and partially overlap in the connected state, the frame 310, 370 parallel to the frame plane. In addition to an aesthetic advantage is through these widening parts 342a, 343a; 342b, 343b, the centering of the frame connection part 340 to the frame 310, 370 reached.

To produce the connection, the threaded rod 352 is first guided through openings 391, 392, 393 in the frame opening-side frame wall 379, the horizontal intermediate wall 381 and the frame wall 380 opposite the frame opening. The openings are arranged so that the threaded rod 352 is completely received in the frame 370 within the main chamber 373 of the hollow profile 371 and that the threaded rod extends obliquely to the plane of symmetry of the frame connection part 340 and the frame 310 on the inside of the inner cover plate 342.

The threaded rod 352 is in turn passed through the insulating plate 341 of the frame fitting 340 into the corresponding prechamber 312 of the other frame 310 where it is anchored to the foremost threaded portion. To improve the aesthetics and to avoid injuries, the hexagon nut 354 fastened to the threaded rod 352 can be provided by a cover, which is held for example by a clamping fit on the hex nut 354.

FIG. 4 shows a cross section through a fourth embodiment of a frame arrangement according to the invention, in which the frame widening is fastened to the frame with the aid of a drilling jig. FIG. 5 shows an oblique view of the fourth embodiment. The basic principle of this frame arrangement 400 corresponds to that of the first embodiment according to FIGS. 1A, 1B. In the following, we will therefore focus primarily on the differences from the first embodiment. The threaded rods 452, 453 are inserted into the insulation plate 441 using a jig 460. For this purpose, the drilling jig 460 comprises a tray body 461, which lateral guide grooves 462, 463 for the threaded rods 452, 453 and on the underside guide rods 464, 465 for two-sided support on the outside of the cover plates 442, 443 and the inner wall 415 and the outer wall 416 of the Hollow sections 411 of the frame 410 are arranged.

The drilling jig 460 can thus be fitted accurately on the frame connection part 440 and the frame 410 and thus centers the frame connection part 440 with the frame 410. The threaded rods 452, 453 are then inserted into the guide grooves 462, 463 and then inserted into the insulation plate 441. The threaded rods 452, 453 have a special grinding in the region of their front end, so that they can easily penetrate into the insulating plate 441 and the frame 410.

The guide grooves 462, 463 are formed on the drilling jig 460 such that the threaded rods 452, 453 are accurately guided during screwing into the corresponding cavities of the frame 410. Before the support part 451, which is arranged in the region of the threaded rod heads, touches the drilling jig 460, the latter can be removed. In the course of the threaded rods 452, 453 safely guided by the already created hole in the insulation plate 441.

Between the frame 410 and the insulation plate 441, a Compriband 458 between the profiles 423, 424 is arranged. This ensures a secure seal between the frame 410 and the insulating plate 441 of the frame connection part 440, which has a simple rectangular cross-section in the present embodiment.

The attachment of the assembled frame assembly 400 in a wall opening by means of a wall anchor 456. This is by two screws 457a, 457b, which are screwed into the corresponding end threads in the threaded rods 452, 453, to the threaded rods 452, 453 and thus to the frame assembly 400th held.

FIG. 6 shows a perspective partial view of a fifth embodiment of a frame arrangement according to the invention. It corresponds in many ways to the arrangement shown in Figures 1 A, 1 B, but has a different support. The frame assembly 500 includes a rectangular frame 510, e.g. Example, a window frame of a window, which is composed of hollow sections 511, and a frame connection part 540, which is held by means of a connecting device 550 on one of the hollow sections 511 of the frame 510.

The frame 510 is again a conventional frame known per se and corresponds to the frame 110 shown in FIGS. 1A, 1B. The frame connection part 540 is again constructed in sandwich construction and comprises a polystyrene foam (EPS) insulation plate 541, which both on the inside and on the outside by a glued with her cover plate 542, 543 made of plastic (eg., PVC) is completed. The fat The cover plates 542, 543 have frame-side widening parts 542 a, 543 a, which on both the inside and on the outside of the frame 510 on the frame connection part 540 facing the circumferential side of the frame 510th protruding out and partially overlap the frame 510 parallel to the frame plane in the connected state.

The connecting device 550 comprises two elongated metal profiles 571, 572 which rest on the insulating plate 541 on the side of the frame connection part 540 facing away from the frame 510 and extend substantially in the main plane of the frame connection part 540. The metal profiles 571, 572 are interconnected by a U-shaped profile 573 made of chrome steel. In the illustrated section, each metal profile 571, 572 has a perpendicular to its main surface oriented, through hole 571 a, 572 a. The spacing of the holes 571 a, 572 a is slightly smaller than the distance of the vertical planes of symmetry of the antechambers 512, 514 of the frame profile 511. The metal profiles 571, 572 lie on a large area on the insulating plate 541. The metal profiles 571, 572 are connected by tapered threaded rods 552, 553 with the hollow profile 511 of the frame 510. For this purpose, the threaded rods 552, 553 are guided through the holes 571 a, 572 a of the metal profiles 571, 572, penetrate the insulation plate 541 of the frame connection part 540 and enter the respective pre-chamber 512 or 514, in which they are screwed. At the rear end of the threaded rods 552, 553, a hex nut 554, 555 is mounted rotatably. In the fastened state, this is supported on the outer surface of the metal profiles 571, 572 and thus creates a tension-resistant connection between the frame connection part 540 and the frame 510.

Due to the smaller compared to the distance between the antechambers 512, 514 distance of the holes 571 a, 572 a include the threaded rods 552, 553 an acute angle of about 1.5 ° with the plane of symmetry of the frame connector 540 and the frame 510 a. The screwing of the threaded rods 552, 553 in the prechambers 512, 514 again takes place as in the first embodiment described in connection with FIGS. 1A, 1B.

The invention is not limited to the illustrated embodiments. It is also executable, for example, with metal instead of plastic frame. Also, the materials of the frame connection part can be varied; Thus, an insulation panel of a different material or a composite of other materials can be used, and the cover plates can be made of a variety of plastics or metals or even of wood.

The geometry of the hollow frame profiles and the arrangement of the individual chambers can also be taken into account individually within the scope of the invention. In particular, the invention can also readily be used with frames in which a frame reinforcement (for example made of metal) is guided in the main chamber. The fastening means can - unlike the illustrated embodiments - are also performed parallel to the plate plane.

Each of the support parts can be held by means of two fastening means (such as threaded rods, screws, profile bars, etc.) on the opposite frame, or it is held only by a fastener. In the latter case, successive supporting parts can each be anchored alternately in the inner and the outer prechamber. Similarly, the arrangement of the fasteners for mounting the frame assembly in a wall opening vary: Fasteners such as wall anchors can be provided on each support member or only a few support members or they can also be attached to the frame connector as needed, regardless of the support members. The support member itself may also be formed directly by the fastener, for example by a wall anchor with additional openings for receiving the fastener.

In summary, it should be noted that a frame arrangement is provided by the invention, which can be realized with a variety of frames and which is quick and easy to produce.
