Description

The invention relates to a frame according to the preamble of the appended claim 1. Such a frame is known from FR-A 2 042 240.

DE 297 03 434 U1 relates to a mounting device for the upper window frame in prefabricated high-rise buildings. There is usually already on site an angle steel available, which complicates the subsequent installation of conventional window frames. DE 297 03 434 U1 proposes now to use this only especially in prefabricated buildings already existing on site angle steel as a holding part for fixing the window frame. In the known holding device of the upper Zargenholm is firmly clamped to the angle steel by means of clamping screws. The achievable stationary connection is found to be essential. The remaining parts are glued. By this state of the art, a tolerance compensation during installation is possible, since due to the clamping of the Zargenholm independently of fixed holding points slidably selectable fixed can be used. When installing but creates a rigid connection.

DE 198 55 622 A1 relates to a clamp for fixing components to be mounted, in particular a setting clip for setting door frames. The setting clip is used as a tool instead of usual wedges and removed after setting the door frame again.

DE 195 44 719 C1 relates to a mounting device for fastening a window insert in einzugauernen soffit frame. This mounting device contains pressurized plug-in pins. These bolts are displaceable with respect to the jamb frame acting as a holding part, while the actual window frame spar is held stationary on the jamb frame.

DE 43 11 793 A1 describes a mounting device for fixing a window frame in a wall cutout. With this mounting device, the window frame is jammed. This one is independent of fixed Fastening bolt; and tolerances can be compensated during installation. After installation, the window frame is firmly clamped.

In DE 87 08 829 U1 attachment of a window frame is described over a left in the renovation leftover wood an old frame. For this purpose, a large bore is placed in the old wood and in the underlying masonry. Therein a long dowel is used. A specially designed screw, which contains a protruding threaded pin on your screw head, is inserted into the long dowel. At the now protruding threaded pin then the new frame is attached. As a result, even with this construction, the window frame is firmly connected to the frame.

From the above-mentioned FR-A-2 042 240 a door frame for a single-leaf door is known. The upper Zargenholm is held against a ceiling in the height direction movable on a holding part. For this purpose, a plurality of adjusting screws are provided on the holding part, by means of which the Zargenholm is height-adjustable screwed to the holding part.

In the prior art frames of the type in question are always anchored to the side and top fixed to the wall and ceiling of the room. For example, frames of doors in which the leaves of one or mehrflügeliger doors are pivotally supported firmly with the wall and ceiling of the room in which the door is provided, braced and in particular also anchored. Apart from the so-called Baufuge there is no effective tolerance compensation between the ceiling and frame, in particular a frame. These can be frames of interior space closures such as doors, wall elements such as fire barriers and fixed glazing in various designs. The frames can be designed differently, including steel, plastic or wood, and in any training, the example of wood, especially as a wood block or Holzstockzarge.

However, the connection of the ceiling-side Zargenholms to the ceiling can cause difficulties when variations, tolerances and deflections occur in the ceiling area, especially with regard to high-rise buildings that perform oscillating compensatory movements under wind pressure, etc., which manifests itself in increasing height with changes in the distance between the ceiling and floor , In these cases, this can be caused by pressure on the frame to corresponding deformations and thus Pinching the closed door leaves or straining the glazing up to damage.

Many of the above references are concerned with exterior windows. The inventions at issue here are about improving the interior doors of buildings.

The invention is therefore based on the object to improve a frame of the type mentioned in the preamble of claim 1 such that the operational readiness and function of built-in with such a frame doors even when installed in high-rise buildings for decades to ensure.

This object is achieved by a frame according to claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention, a ceiling spar with free-swinging compensation can be achieved, which is intended in particular to exclude any subsequent deflections caused by whatever reason, or primarily a compressive load or other load on the connection between the wall-ceiling on the one hand and the door on the other hand. On the other hand, in the prior art in door frames, there is consistently a firm locking of the cover side frame spar and thus a prevention of ceiling compensation.

Although a cover slidably sliding in the vertical direction attachment is known for example from DE-A 24 39 979 for partitions. However, these are always solid room closures that are not comparable in function with doors. The known sliding displaceability thus serves for partitions completely different purposes, for example, to allow easier installation.

By a rolling or preferably sliding displacement between a holding part and the actual upper Zargenholm can be compensated for example by building movements, especially in high-rise building tolerances. Thus, even long after the installation of the frame, can be compensated for building movements and prevent their detrimental consequences for doors.

In the case of a door frame proposed mounting means for the approximately parallel to the ceiling Zargenholm this is held on a single or multi-piece, fixed to the ceiling holding part freely slidably at least in the vertical direction.

By such a sliding support of the ceiling side Zargenholms to be determined on the ceiling holding part a range of motion is created, can be compensated with the fluctuations, tolerances and Versetzbewegungen the ceiling relative to the frame. It is primarily provided a sliding displacement possibility in the vertical direction, it can also be provided with respect to high-rise fluctuations lateral shifts by appropriate sliding guides or interventions involving play between frame and cover-side holding part. The frame learns in the area of the ceiling side Zargenholms a bracket relative to the ceiling, which corresponds to the required stability of the Zargenverankerung total.

According to the invention, a form-fitting sliding guide device is provided, which permits a displacement of the cover-side frame member relative to the ceiling and / or the wall of the room in a height direction and blocks a displacement thereof in a direction perpendicular to this height direction. The Zargenholm can therefore move relative to the ceiling to compensate for building fluctuations to some extent in the vertical direction, but not in the direction perpendicular thereto or only to the extent limited extent. As a result, despite the compensation possibility, a good stability and strength of the frame is achieved, which is especially in door frames of heavy special doors (burglary, bulletproof, fire doors, smoke doors, radiation protection doors, ...), where the pivoting movement of very heavy door leaves of the frame and be supported on the wall, is advantageous.

The holding part of the mounting device formed as part of the frame may comprise a rod extending in the longitudinal direction of the cover side frame beam, in particular in the form of a beam, or a plurality of rod sections arranged successively in this direction, in particular in the form of beam sections, which or relative to the Ceiling remaining fixed at the installation location or can be fastened. Thus, the holding part can even contribute to the outer visual appearance of the frame and remain uncovered to some extent, without this being unfavorable for the appearance of the door.

In a height direction extending connectors or running in a vertical direction sliding guide, for example, formed by a means for positively guiding a sliding movement (hereinafter called sliding guide means) may be provided to connect the holding part with the cover side Zargenholm slidably. For example, it is provided in a concrete embodiment that the sliding guide device has a male element on the holding part and / or the Zargenholm and a corresponding, correspondingly formed on the Zargenholm and / or the holding part Einsteckausnehmung.

By means of plug-in connections or similar sliding guides, it is possible to allow desired sliding movements for the purpose of tolerance or motion compensation, but to prevent undesired displacements of the frame. The slide or the connectors can be equipped with more or less large game, so that the Zargenholm in the height direction according to the guide path is free and displaceable in the vertical direction in the context of the game. However, embodiments are also conceivable and desirable in some installation situations in which a backlash-free and even with (low) frictional resistance clamping guide is provided. The frictional resistance of the guides or connectors are always such that building dislocations or building movements are automatically compensated without affecting the frame and / or the door or the function or appearance. A (light) terminals or a (light) frictional engagement could be advantageous, for example, during assembly of the upper frame handle for handling it before its final attachment or also with regard to the stability of the frame. Also possible are hybrids, for example, such that a sliding guide with little or no resistance in one direction, preferably the height direction, and a sliding guide with greater resistance in another direction is provided. Instead of a sliding guide roller guides or the like for guiding the two mutually movable sub-elements of the frame are possible.

Preferably, the sliding guides or connectors are concealed, so as not to adversely affect the visual appearance of the room finish. For example, it is provided that the frame in the longitudinal direction in the ceiling to be fastened to the holding part, the latter in the height direction displaceably held Zargenholm and a positive Gleitführungseinrichtung is divided therebetween and having a cover for covering the Gleitführungseinrichtung.

As a cover member for covering guide means may be attached to the sliding Zargenholm or integrally executed with it strip member serve. For example, the Zargenholm itself be provided with a flange-like portion for covering a gap between the holding part and Zargenholm. But also a fixed or to be fastened to or integral with the stationary to be fastened holding part bar can serve as a cover.

In order to cover the above-mentioned gap on both sides, it is advantageously provided that the cover side frame spar is composed of a plurality of profiled bars, which are each provided with the flange-like portion for forming the sliding guide means covering frame mirrors.

Between the mutually displaceable sub-elements of the frame sealing or sliding strips can be arranged. These can, for example, maintain a tightness-proof closure despite the possibility of transfer. For example, between the side surfaces of the above-mentioned rod or beam or the beam or rod sections and these cross-over Zargenspiegeln the ceiling-side Zargenholms sealing and / or sliding strips may be arranged.

In a preferred embodiment, plug connections are created by engaging in corresponding insertion plug-in pins. The locking pins can be attached by suitable connection methods to one of the mutually movable sub-elements of the frame member. For example, metal bolts are provided with heads that engage positively in a cavity in the sub-element and / or clamped with force fit with this sub-element for common movement relative to the other sub-element having the insertion, are braced.

In a further preferred embodiment, in addition to or as an alternative to a plug-in bolt connection, it is provided that the holding part has an engagement rail arranged in one or in the longitudinal direction, fixed on the ceiling or to be fixed, which points downwardly into a groove-shaped recess in the upwardly projecting web Surface of the frame spar is used.

For forming cover elements is then preferred that the engagement rail are assigned on both sides parallel strips, between the mutually facing side surfaces and the respective opposite side surfaces of the cover used in the holding position Zargenholms the sealing and / or sliding strips are arranged. Preferably, the strips are to be mounted directly on the ceiling, although an attachment to or integral with the holding part or the engagement rail is conceivable and advantageous.

According to the invention, the mounting device is a component of a frame of a single or multi-leaf door, in which the door leaf or the door leaves of the door are pivotally held. The frame according to the invention has the cover-side Zargenholm, which can be held by the support means at least in the height direction slidably relative to the ceiling. The frame may be, for example, a wooden block frame or a wooden frame.

Particularly preferably, the frame is designed as part of a fire and / or Rauchschutzabschlusses. For this purpose, it is provided with at least one strip of intumescent under heat material. The strip is used in case of fire for sealing gaps formed between individual sub-elements of the frame member and / or between a sub-element of the frame and the ceiling or the wall of the room.

The upper connection of the frame to the ceiling is flexible in terms of materials. The holding part, which is first attached to the ceiling - and could also be in the form of an angle -, could be made of wood, metal, especially steel or other materials, including composite materials or mixtures of materials, while the Zargenholm and / or the rest of the Frame could also be made of wood, metal or other materials as well as hybrid forms.

Embodiments of the invention will be explained in more detail with reference to the accompanying drawings. It shows:

Fig. 1

a cross-section through a first embodiment of a fixed to a ceiling of a space frame member; and

Fig. 2

a cross section through a second embodiment of a fixed to a ceiling of a room frame member.

In the following, two reproduced in the drawing embodiments of ceiling-side frame sections of doors, and special doors are explained in more detail. The figures each show parts of a frame of the door. The frame is in the example shown in Fig. 1, a wooden block frame built on the basis of wood materials fire door with smoke protection function and in the example shown in Fig. 2, a wooden frame of such a door.

The drawings each show a horizontal section through the extending approximately parallel to the ceiling, ceiling side Zargenholm in its installed position on a holding part also shown cut, which is fixed to the building ceiling.

Fig. 1 shows a generally designated 1 support means, with the help of the ceiling 2, a total of 3 designated ceiling-side Zargenholm a wood block frame is held.

To form a holding part is in the space below the ceiling protruding rod, here in the form of a bar 4, fixed to the ceiling 2 with fastening means not shown. The bar 4 extends in the direction of him to be determined, parallel Zargenholmes 3. The bar 4 preferably has at least substantially the length of the Zargenholmes 3 on.

Between the holding part of the holder 1, i. here the beam 4, and the Zargenholm 3 a sliding guide device is provided. This is formed in the first embodiment by connectors, here in the form of pin 5 and holes 6 as engagement openings for receiving the same. With the help of the fixed to the Zargenholm 3 locking pin 5, which are provided in the provided in the bar 4 correspondingly matching holes 6, the ceiling-side Zargenholm 3 is slidably connected to the beam 4. The locking pins 5 are supported by bolt heads 7 on the Zargenholm 3.

The wooden block frame is equipped with frame mirrors 8 and 9. For this purpose, the Zargenholm 3 in several, here two, connected to each other via tongue and groove engagement profile bars 20, 21 divided with L-profile. As a flange-like section forms one of the legs of each L-profile The frame mirrors 8 and 9 overlap in the installed state between their laterally mutually facing surfaces opposite side surfaces of the beam 4. In the overlapping areas each sealing or sliding strips 10 are arranged, here in such a way that the slide strips are fastened to the frame mirrors 8, 9.

In order to make the Gleitverschiebbarkeit in the height direction correspondingly spacious, 2 cavities 11 are formed above the locking pin 5 in the ceiling.

The determination of the beam 4 on the underside of the ceiling 2 can be done via an insulating intermediate layer 12. Trained as sliding strips sealing strips 10 prevent passage through the formed between the frame beam 3 and the beam 4 gap 22. In particular, the passage of smoke is thereby prevented in case of fire. Next here is a strip 23 provided from intumescent under heat material to prevent the passage of fire in case of fire.

Fig. 2 shows a differently constructed mounting device, which is designed for the mounting of a cover-side Zargenholms 13 of a wooden frame. The holding device comprises an engagement rail 14 to be fixed on the ceiling side, which extends in the longitudinal direction of the frame member 13 and preferably has approximately its length. This engagement rail 14 is fixed in a manner not shown on the lower surface of the ceiling 2 adjacent to this and has a web 15 which engages in a correspondingly extending groove 16 in the ceiling 2 facing the surface of the frame member 13 slidingly slidably, as the Trace drawing. As a result, a sliding guide device between the Zargenholm 13 and acting here as a holding part engagement rail 14 is provided with the web 15 as a male or male member and the groove 16 as an engagement or Einsteckausnehmung.

Parallel and on both sides of the engagement rail 14 cover elements in the form of strips 17 and 18 are mounted, in the present case in turn fastened in a manner not shown directly on the underside of the ceiling 2 projecting from this. In principle, the engagement rail 14 with the strips 17 and 18 may also be integrally formed.

The strips 17 and 18 are arranged spaced from each other such that their mutually facing side surfaces of the Zargenholm 13 more or less accurately between take up, so that in each case the side surface of one of the strips 17 and 18 with one of the side surfaces of the Zargenholms 13 opposite. The inclusion of Zargenholms 13 between the strips 17 and 18 is sealed by mounted in the region of the opposite side surfaces sealing and wear strips 10, which are fixed in the present case in the strips 17 and 18. The sealing strips 10 embodied here as sliding strips serve to seal the gap 25 between the ceiling 2 and the displaceably mounted frame rail 13, for example against the passage of smoke in the event of fire. In the example shown here further have both strips 17, 18 and the Zargenholm 13 on the respective ceiling 2 facing side depending on at least one strip 26 of intumescent under heat material to seal the gap 25 against passage of fire in case of fire.

As the drawings show, the at the ceiling-side bracket at least in the height direction sliding sliding frames are not only independent of the material and the shape, but also suitable for doors of certain tasks such as sound-absorbing, smoke-tight or fire retardant trained door and frame areas. Here, the sealing or sliding strips can represent special measures in terms of sealing.

Although the above-mentioned embodiments relate to the basis of wood-based construction of frames of doors, corresponding support means, which allow a sliding or roll-rolling use of rolling bearings of an upper frame member, also possible in various other embodiments of room closures. Accordingly, an upper frame element could be formed by fixed glazings or by inner wall elements.
