Description

DESCRIPTION

Rear feedback device and wraparound frame supplied with it

The invention relates to a wrap-around frame with adjustable mouth width, and with a feedback device for feedback of the frame. The invention also relates to the uses of such a wraparound frame, and to a method for assembling such a wraparound frame.

The frames are used in masonry jambs, and serve to hold a door leaf. Conventional frames usually have at least three frame beams (also referred to in the following as frame bars) which are connected to each other. The frames are usually made of wood or metal materials, such as steel. Next, the main focus will be on these steel or metal frames. For the assembly of the known frames, these are first placed on a masonry jamb. The frame is then connected to the masonry using suitable fasteners, in particular fastening screws. In order for the frame to maintain its position during assembly, in many cases a spacer element is inserted between the masonry and the frame. It is often difficult to insert a spacer between the frame rail and the wall jamb, especially if the distance between the frame rail and the wall jamb is very small.

From document DE 102014116290 A1 a metal wrapping frame with adjustable mouth width is known, which is provided with a first partial frame bar designed as a metal profile part, and a second partial frame bar designed as a metal profile part , the partial bars being configured to surround an area of the wall, and to adjust a width of the mouth, they fit together in a displaceable manner with respect to one another. The fastening of the frame takes place through a screw-tenon fastener, placed at an angle, by means of a fixing angle, or through foaming by means of mounting foam. In addition to its simple assembly, and its aesthetic appearance, the wraparound frame is characterized by the fact that it can be fastened dry, without subsequent mortar or masonry work.

An anchor adjusting element is spot welded inside the counter-frame housing, the anchor adjusting element being screwed to the steel support profile. The anchor adjusting element also has a snap-in recess, into which the main casing of the frame can be snapped. Subsequently, the counter frame wrap and the main frame wrap are firmly screwed into a groove area.

DE 20 2015106530 U1 discloses a side part of the door frame for a multi-casing sheet steel door frame, essentially consisting of a front casing profile and a rear casing profile, which can be inserted into the same. The front casing profile is firmly welded with a spacer element, which has a mounting surface. The front wrapping profile is attached to the wall opening, by filling a space between the mounting surface and the wall face with mounting foam. The rear wrap profile is then clamped between the rear of the mounting surface and a flange of the front wrap profile.

It is preferred that the feedback device has a first spacer element with a clamping barb, and at least one second spacer element without a clamping barb, the first and second spacer elements being configured to be traversed by a set screw, and the second spacer element to be able to overlap, support and / or strongly clamp the clamping tab when the clamping screw is tightened.

A preferred embodiment of the invention relates to a wrapping frame with a feedback device, which is preset on a soffit, for a frame bar of the door or gate frame. Another aspect of the invention relates to a spacer element for use in such a wrapping frame, and to a method for feeding back the preset frame spar of the frame.

Preferably, a feedback device is provided, for a predetermined frame beam, of a door frame, in particular fire doors, which has at least one spacer element for feedback of the frame beam, the spacer element having an installation clamping screw for fixing to a shaft, in particular to a threaded shaft, of a fixing element. Preferably, the frame spar is divided into several partial frame bars, in order to configure a frame with a width of adjustable mouth.

In an advantageous embodiment, the feedback device is configured in such a way that it is possible to feed back a frame member in a simple way and without any help, especially without tools.

In the use of the feedback device, and before the frame is fed back with the spacer element, the frame, and in particular the frame bars, are previously fixed on the wall by means of fixing elements. This pre-fixing takes place, advantageously, in the jamb of a masonry, the surrounding area of which has already been largely completed. Here it can be, for example, a structure (dry construction) or a masonry that is already finished and largely plastered. Thus, there is only a small space between the frame bar and the jamb, through which the fastening element must be inserted.

The spacer element is inserted through the slot between the frame bar and the jamb, and is fastened to a threaded shaft of the fastener by means of the fastener clamping device. Advantageously, the clamping device for the fixing elements produces a clamping effect.

With a flat and plate-like configuration of the second spacer element, it is also possible to insert the spacer element into a small space between the masonry and the frame bar, or between the masonry and the first spacer element, and fasten it to the shaft. threaded, without using an assembly aid.

For insertion, the spacer element is grasped by a side opposite the elongated hole, and is inserted into the space between the frame bar and the wall jamb, and is pushed onto a threaded shaft of a fixing element by means of the elongated hole. The spacer element is then preferably pushed onto the threaded shaft of the fixing element, either by pressing it fully, or with a tool, such as a hammer, until it hits an area of the leg of the frame bar.

In an advantageous configuration, the clamping device for the fixing elements is a hole configured as elongated. Due to the conical configuration of the elongated hole, a clamping effect is achieved, which increases the further the spacer element is pushed onto the threaded shaft of the clamping element. Furthermore, an elongated conical hole is presented as an inexpensive way to produce a fastener holding device.

In an advantageous configuration, the second spacer element has an anti-tip stop. Advantageously, the roll-over stop is rectangular in shape for ease of manufacture. Preferably, the anti-tip stop is configured in such a way that it counteracts an inclination of the spacer element, in the clamped state. On the one hand, the anti-tilt stop counteracts the tipping of the clamped spacer element and, on the other hand, the anti-tip, in the stop state, ensures that a spacer element inserted at an angle reverts to a horizontal position.

Advantageously, the second spacer element is designed asymmetrically.

The invention provides a spacer element as a feedback device for a wrapping frame. The spacer element is characterized through its fastening device for the fixing element, which is preferably an elongated hole configured in a conical shape. The clamping element holding device serves to clamp the spacer element on a threaded shaft of a clamping element. Furthermore, the spacer element has an anti-tilt stop, which prevents the spacer element from tilting, and serves to align the spacer element in the inserted state. Furthermore, the spacer element is also characterized by its ease of assembly.

Advantageously, a spacer element in the form of a bridge or in the shape of a U, which has a bearing area with an opening for passing a fixing element, and a clamping lug with clamping feet, is used as the first spacer for feed back a part of the frame, on the hinge side, of a wraparound frame with adjustable opening width for a fire door, which can be inserted movably, in an insertion area between the clamping legs of the clamping flange and a profile area of the part of the frame on the hinge side, an area of insertion of a part of the frame, opposite the hinge side of the surround frame, for adjusting the width of the mouth.

A preferred procedure for assembling a wrap-around frame comprises the steps:

a) previous fixation, somewhat loose, of a first partial bar of the frame by means of several fasteners to an area of the wall;

b) feedback of the first partial bar of the frame with a feedback device, the spacer element being pushed, in at least some of the fastening points to the spacer element, configured with the fastening tab, on an axis of the fastener, and, if necessary, other spacer elements without retaining lug, until the first partial bar of the frame is fed back with the desired distance to the wall area;

c) insert an insertion zone of the second partial bar of the frame, in order to achieve the desired width of the mouth,

d) fastening the fasteners, so that the first partial bar of the frame rests firmly on the feedback device.

Furthermore, the invention thus relates to a method for feeding back a previously fixed frame bar, the frame being fed back with a spacer element of a feedback device. The procedure ensures the introduction of a spacer element between a frame bar and the partition, in a very late construction phase, especially in the final stage, leaving a very small space between the frame beam and the wall jar for the insertion of the spacer element. To do this, the spacer element is grasped on a side opposite the elongated hole, and inserted into the gap between the frame rail and the wall jar, and by means of the elongated hole it is pushed onto a threaded shaft of a locking element. fixation. The spacer element is then pushed onto the threaded shaft of the fixing element, either by pressing it by hand or by means of a tool, such as a hammer, until it collides with an area of the leg of the frame bar. Furthermore, the procedure can also be used to feed back a frame bar whose periphery is still largely unfinished.

Advantageously, the spacer element is fixed on a threaded shaft of a fixing element by means of an elongated hole, until an anti-tip stop of the spacer element collides with the bar of the frame.

A preferred configuration of the invention achieves a wrapping frame with a feedback device, with the special feature that an adjustable mouth width can be achieved also for fire protection. This is achieved in particular by adapting a first spacer element. At least one clamping lug is configured on the first spacer element. Through this, a clamping clamp can be configured at the fixing points, where the part of the frame profile on the opposite side of the hinge can be engaged.

In this way, a spacer can preferably be formed into a clamping bracket by means of bends. Through the combination of a fastener, such as a dowel fastener, or another fastener suitable for the respective material of the wall area, with at least the first spacer element, configured with the fastening lug, You can achieve a very firm and secure holding of a part of a frame profile on the hinge side - example for the partial bar of the hinge side frame -. Through this, the forces exerted on a fire door leaf, in the event of a fire, can be diverted through the door hinges and the counter support for the door lock, or its latch, which is also set on the hinge side. If necessary, even more spacers are used for feedback, preferably without the clamping plate, and more preferably executed like the spacer elements shown and described in DE 10 2009 057 040 A1, so that feedback is achieved. adapted correspondingly to the distance between the first partial bar of the frame and the area of the wall.

The first spacer has the holding tab. In the groove between the fastening tab and a profile area of the first partial frame bar, an insertion area of the second partial frame bar on the opposite side of the hinge is inserted.

Preferably, the second partial frame bar has essentially a covering function, while all other frame functions are fulfilled through the partial frame bar on the hinge side.

According to another additional aspect, the invention relates to a method for assembling a wraparound frame, with adjustable mouth width, according to one of the configurations described above, comprising the steps:

a) preliminary fixing, somewhat loose, of a first partial frame bar, to be used as a partial frame bar on the hinge side, by means of several fasteners to an area of the wall;

b) feedback of the first partial bar of the frame with the feedback device, which has at least one spacer element, configured with a fastening lug, the spacer element being pushed, in at least some of the fastening points to the spacer element , configured with the clamping tab, over the holder, and other spacer elements being pushed, if necessary - preferably without clamping tab - until the first partial frame bar is fed back with the desired distance to the wall area ;

c) insert an area for inserting the second partial frame bar, which will be used as a partial frame bar on the side opposite the hinges, in order to achieve the desired width of the mouth,

d) fastening the fasteners, so that the first partial bar of the frame rests firmly on the feedback device.

In one configuration of the method, step c) is carried out before step d). In this, the clamping force of the clamp joint is preferably increased through tightening of the fastener. For this, a second spacer element, without a clamping lug, is particularly preferably used as a clamping jaw for the clamping lug fixation.

Particularly preferred embodiments of the invention have the advantages that are explained in more detail below.

Preferably, a first frame part is designed in such a way that it can also be used alone as a corner frame. Especially the first part of the frame is formed through a standard corner frame. A special feature of a preferred configuration of this corner frame is the possibility of mounting inclined dowels directly in an area of the profile of the corner frame. This is achieved in particular through cup-shaped recesses in an area of the profile of the corner frame. These cup-shaped cavities are preferably provided at a base of a fold on the side of the jamb, at a step of the fold of the corner frame. The corner frame has in particular two zones, which form the two step flanks of the fold step. In a first area of the profile, which has to be placed parallel to the jamb (fundamentally perpendicular to the main surface of the door leaf, when the door is closed), a fastener housing is provided, in which it also takes place fixing by fasteners. In this first area of the profile, the first step flank of a fold step of a stop fold is formed. Furthermore, a second section of the profile is provided, which forms the second step flank of the fold step, and thereby forms the stop for the door leaf, and consequently protrudes further.

Preferably, a spacer element of the feedback device preferably has a first support area to support the first area of the profile, and a second support area to support the second area of the profile. This second support area serves at the same time as a holding area for fixing a counter frame (second part of the frame).

In particular, a universal frame is configured, which can be used both as a corner frame and, with a second part of the frame, as a wrap-around frame, with an adjustable mouth width. In particular, a universal frame is achieved with a telescopic counter frame.

This universal frame has in particular a corner frame with a cut-out for a diagonal clamping, a clamping lug with a clamping area (example for the first spacer), a set of cladding parts (spacer plates - example for the second spacer) and an additional frame (counter frame - example for the second part of the frame).

In some configurations, one or more fastening lugs may also be additionally provided, which can additionally be used in the intermediate region between the fastening points, and can serve to fasten the frame.

An assembly is preferably carried out in such a way that the corner frame is fixed (with stamping for diagonal fixing), a plug is pressed, through the corner frame, into a corresponding hole in the wall, the fixing lug (i.e. first bracket retainer) is inserted between the wall and the corner frame (around the dowel of the screw-dowel fastener), and if necessary, filler pieces are inserted between the clamping lug and the wall (around the block). Then follows a fixation with a screw of the screw-dowel holder. The trim is then clamped between the fixing lug and the corner frame.

Preferably, when the screw is firmly tightened, both a clamping of the corner frame and a clamping of the counter frame between the clamping lug and the corner frame.

Spatially, a frame can be configured without a support on the ground.

Few attachment points are sufficient for each side bar, for example three attachment points per side bar.

A lower fixing point replaces an additional anchor for frames without ground support.

The frame can be used universally: - masonry - reinforced concrete wall - lightweight construction walls. The frame presented here forms a further development of the wrap-around frame described in the previously unpublished German patent application DE 10 2016 114 966.7. For more details express reference is made to this German patent application.

This frame has only been further developed in the sense that now a standard corner frame with diagonal fixation can be attached to a telescopic counter frame by a clamping procedure.

The resulting universal frame through it can be used on various types of walls: masonry, reinforced concrete wall, light wall, etc.

The exemplary embodiments of the invention are explained in more detail below, according to the attached drawings. They show:

A preferred embodiment of a surround frame 210 for a fire door is shown in Figures 1 to 5. Surrounding frame 210 has a first frame part 212 and a second frame part 214, which can be movably joined together by means of a clamp connection 216, thus establishing a mouth width of the surrounding frame 210, and a feedback device 218.

In the example shown, the first frame part 212 is a part of the frame on the hinge side, to which the door hinges (not shown) are attached, and on which an opposite housing for a lock is configured. a door leaf (not shown) from the fire door. Door leaf examples are shown and described in DE102005023426B3, or DE102010005719B4, or DE102010044195A1; for more details of the door leaf reference is made to these publications. The opposite housing is hereinafter referred to as the opposite housing of the lock. The first part of frame 212 is designed as a standard corner frame, and it can also be used as a corner frame only, if a corner frame and no surrounding frame is desired. The individual frame bars of the first frame piece 212 are profiled and configured like those of the frame bar of document DE 20 2009 001 225 U1 and, as shown there, can be used as frame bars of a pure corner frame .

In the example shown, the second frame part 214 is a frame part on the opposite side of the hinge, which has primarily a covering function, but no clamping function, and has an insertion zone 224 that can be inserted into an insert area 226 in the first part of the frame. The insertion zone 226 is part of the clamping connection 216.

The feedback device 218 serves to feed back the surrounding frame 210, in order to connect the surrounding frame 210, firmly and without play, to an area of the wall. For this, the feedback device 218 has at least one first spacer element 228, and if necessary at least one second spacer element 230, in order to bridge a distance between a bar 232 of the surround frame frame 210 and the area of the Wall. Depending on the size of the distance, more or less second distance elements 230 are used.

On the first spacer element 228, which is shown in detail and individually in Figures 6 to 11, at least clamping lug 234 is configured to configure clamping connection 216.

The first and second spacer members 228, 230 are preferably configured so that a screw 238 passes through, so that, through tightening of the screw 238, the spacer members 228, 230 are compressed together. The second spacer element 230 preferably has a clamping jaw area 231, which bears against the clamping lug 234, and can press it firmly against the insertion area 224.

The first frame part 212 presents a plurality of first partial frame bars 236, in order to thus configure a frame with at least three sides. In particular, a first partial frame bar on the hinge side 236, a first partial upper frame bar, which will be positioned horizontally above, and a first partial frame bar on the lock side are provided. In this, in the representations of Figures 1 to 5, only one of the partial frame bars 236 is shown, to be placed vertically, which can be the first partial frame bar on the hinge side, or on the side of the frame. the lock. All the first bars 236 of the frame are configured from a metal profile, especially a steel profile, the profile contour of which can be seen especially in Figures 1 to 5, and in DE 20 2009001225 U1, or in DE 20 2008 000 835 U1 (to which reference is made for further details). Accordingly, a Z-shape is provided as the basic shape, with the end regions 242 folded back. Through the Z-shape a stop fold 244 is configured to accommodate the closed door panel. On a first flank 246 of the stop fold 244, a row of fastener housings 248 are provided, distributed along the two first partial bars 236 of the frame, which are to be positioned vertically. On the second flank 250 of the stop fold 244 a sealing groove 252 is configured for a door sealing strip (not shown).

The fastener housings 248 have cavities 254, configured in a partially sloped cup shape, for complete housing of the screw heads of the screws 239 of the screw-dowel fasteners 238. For more details on these cavities 254, and on the fasteners 238, reference is made to DE102009057037A1 and DE202009001225U1. In particular, the cup-shaped cavity 254 (after tightening the fastener) can be covered with a cover cap (not shown), such that the cover cap is flush with the surface of the first flank 246. In this way , a concealed, optically high-quality installation can be achieved.

The bars 236 of the first part of the frame thus present a first zone 240 of the profile that configures the first flank 246, and a second zone 243 of the profile that configures the second flank 250. When used according to the definition, the second zone of the Profile 243 is located further away from the jamb towards the inside of the door opening to be closed, and configures the stop for the door leaf, and presents the sealing groove 252 for the door's weatherstrip. When used as a pure corner frame, this second section of profile 243 can be lined with mortar or the like on its rear side (side opposite the stop profile 244), so that the door frame is only configured in one corner of the jamb.

The first spacer element 228 is configured such that it can also support the corner frame during this function. Therefore, no further spacer devices are required, apart from the first and second spacer elements 228 and 230.

As can be seen especially in Figures 1 to 5, the feedback device 218, in the example shown here, has a first spacer element 228, and where appropriate one or more second spacer elements 230, for each holder 248.

In this, the first spacer elements 228 are configured in such a way that they support the different profile areas 240, 243 of the first bar 236 of the frame, which must be aligned approximately in parallel with respect to the jamb, and at the same time configure a clamp clamping device 216. Thus, the first spacer element fulfills the function of the spacer device (see reference number 21 of DE 202009001225111), and of the spacer element (see reference number 22 of DE 20 2009001225 IM ) of the frame member described in DE 202009001225 U1, as well as the function of the retaining lug shown in DE 202009009444 U1 (see there reference number 38), as well as the function of the first spacer element of the application German patent 102016114 966.7, which has not been published.

The second spacer elements 230 are configured as described and shown in more detail in DE102009057040A1. Consequently, the second spacer elements 230 are configured as plates, which have at one end a slot-shaped recess, with which they can be pushed and held from the side on a previously fixed axis of the screw-dowel threaded fastener. 238, an anti-tilt stop being provided against lateral tilt.

An exemplary embodiment for the first spacer element 228 is explained in more detail below, according to Figures 6 to 11.

The first spacer element 228 is manufactured from a sheet metal part 258, as shown in Figure 11. The sheet metal part 258 is stamped from a sheet metal, with a sheet thickness that is less than the sheet thickness of the second spacer element 230.

By way of example, the thickness of the plate of the second spacer element 230 is greater than the thickness of the plate of the first spacer element 228, by a factor of 1.2 to 2, preferably 1.33-1.5

In the sheet metal part 258 a central area 310 is configured, which is configured, in a plan view from above, approximately at right angles to the outer perimeter contour. From this central area 310, two lugs extend laterally, at a first end 312, to configure a first clamping leg 314 and a second clamping leg 316, which are joined by a rib area 318 of the clamping lugs.

At the second end 320, opposite the first end 312, the opening 278 is configured in the form of an elongated hole 280, with a funnel-shaped insert opening 284. Furthermore, in this area of the sheet metal part 258, which is arranged at a second end 320, two flags are supported to configure a first support leg 322 and a second support leg 324. The flags to configure the support legs 322 are configured longer than the flags to configure the clamping legs 314, 316, viewed in the direction from the first end 312 to the second end 322 (longitudinal direction of the sheet metal part 258). The flags for configuring the clamping legs 314, 316 extend laterally further from the central zone 310 than the tabs for forming the support legs 322, 324. Between the respective ear for configuring the support leg 322, 324, and the lug for configuring the clamping leg 314, 316, a slot spacing 326 is configured on each side so that the flags can be folded apart from one another in the manner shown in Figures 8 to 10.

At the edges of the free lateral end edges 328 of the lugs 314, 316, which form the clamping legs, a projection-recess formation 330 is provided, the corner edges 332 of the projections 334 being configured, facing the end. closest - first end 312 - shaped inclined at an obtuse angle, in order to thus configure entry slopes 336. At the ends of the projections 334, opposite the inclined corner edges 332, a sharp end edge 338 is configured, for example through a notch, at a right or acute angle. Through the protrusion-recess formation 330, the lugs that make up the clamping legs 314, 316 are provided with a serrated end edge 328. By way of example, two projections 334 are configured with a recess between them.

The lugs that make up the support legs 322, 324 are provided with a straight end edge 340.

The support legs 322, 324 are bent, with respect to the plane of the central zone 310, by means of a bending of the corresponding lugs that are configured at the first end 312, by less than 90 °, by way of example from 80 ° to 60 °, and more especially 70 °, so that the clamping legs 314, 316 of the area of the rib 318 of the clamping lug, configured between them, try to come out inclined outwards. Through this inclined arrangement of the clamping legs 314, 316, they can be elastically flexible to exert a clamping effect.

The lugs that make up the support legs 322, 324 are bent 90 ° and therefore move away from the plane of the central zone 310 at right angles.

Through this, a first support area 342 is formed in the first spacer 228, which is formed through the support legs 322, 324 and the rib area 344, configured therebetween. This first support area 342 serves, see Figures 1 to 5, to support the first area 240 of the profile, and especially to support the area of the first flank 246 of the stop fold 244, provided with the housing 248 of the fasteners. In this, the first support leg 322 and the second support leg 324 are supported by the indicated use of the surrounding frame 210 or the corner frame (for example, also when only the first part 212 of the frame is used, and not the second frame portion 214, which may be referred to as the counter frame) above and below the fastener housing 248. Through this, the first frame part 212 can be well clad and supported.

Furthermore, the first spacer element 228 is provided, at the first end 312, with a second support zone 346, which at the same time acts as a clamping lug 334. This second support zone 346, which also forms the clamping lug 334 , is configured through the first clamping leg 314, the second clamping leg 316, as well as the rib area of the clamping tab 318, configured between them. The clamping legs 316, 314, which protrude at an angle, are configured to support the second zone 343 of the profile, with its end edges 328 serrated. At the same time, the clamp legs 314, 316 form part of the clamp joint 216.

Through the inclined corner edges 332, the insertion zone 224 of the second end 214 of the frame can be inserted into the insertion zone 226, configured between the serrated edges 328 of the clamping legs 314, 316 and the edge zone end 240 of the second zone 243 of the profile. The clamping legs 314, 316 can be deflected, due to their inclined arrangement, and exert an elastic clamping load. At the same time, the sharp corners 338 provide for increased strength in the direction opposite to the insertion direction, so that the second frame part 214 is held well.

The second part of the frame 214 is represented in Figures 1 to 5, together with the first part of the frame 212. It has, in a manner not shown, several second partial bars 288 of the frame, which are joined in the areas of corner with a bolted corner joint, and thus form a frame of at least three sides. In Figures 1 to 5 only a second partial frame bar 288 is shown, to be placed vertically as in the case of the first frame part 212, the other second partial frame bars have an identical profile.

The second main bars 288 of the frame are made of a metal profile, especially a steel profile, the profile shape of which can be better understood from Figure 1. Consequently, the profile is L-shaped, with a first L-shaped leg 294. , a second L-leg 296, and an additional end flange 298 folded back at right angles on the second L-leg 296 (expressed another way, the profile is roughly U-shaped, with two legs 294, 298 in U and a web 296 therebetween, one leg 294 in U being significantly longer than the other leg 298 in U).

The second L-arm 296 has the function of a mirror frame, while the end zone of the first L-arm 294 forms the insertion zone 224.

The insertion area 224 of the second partial bar 290, on the hinge side, can be assembled, by means of the clamping connection 216, with the first partial bar 236 of the frame part, on the side of the hinges, to forming an adjustable frame spar 232, on the hinge side of the surrounding frame 210, which can be adjusted in its mouth width by relative displacement of the partial frame bars 290, 236. Correspondingly, the first upper part bar of the frame (not shown) and the second upper part bar of the frame (not shown), together make up an upper part bar of the frame, and the first part bar of the frame on the side opposite the hinge (also not shown), and the second part bar of the non-hinge side frame (also not shown), together make up a bar of the non-hinge side frame.

The clamping connection 216 is formed therein through the first spacer elements 228, arranged on the first vertical partial bars 236 of the frame, more precisely their clamping lugs 234, and the adjacent area of the profile of the first vertical partial bars 236 of the frame.

The assembly of the surrounding frame 210 proceeds as follows.

The frame of the first part of the frame 212 is placed in the opening of the building to be closed through the fire door, and the screw-dowel fasteners are inserted obliquely, in the area of the wall, in the fastener housings 248 to be used, but initially only pre-attached, and not yet tightened. For example, initially only plug 237 can be inserted.

Subsequently, the first spacer element 228, with its opening 278, is first pushed from the side onto the shaft, or here in particular, onto the fastener lug.

Thus, the first spacer element 228 can be pushed over a part of the pre-attached fastener, as described and shown, for the second spacer, in DE102009057040A1. The first spacer element 228 is pushed therein, as the first element, onto the workpiece (in this case, the dowel 237). In the event that there is still another distance to be bridged between the metal profile of the corresponding bar 236 of the frame and the area of the wall, a second spacer element 230 can also be inserted; if necessary, several second spacer elements 230 will be used. The frame part 212 can then be fixed by screwing in the screw 239.

The insertion zone 224 is then inserted, before the plug-screw fasteners are fully tightened. In this form of the method, the dimensions and thicknesses are preferably selected in such a way that the clamping force of the clamping joint can be reinforced by the action of the clamping jaw 231 of the second spacer element 230. Thus, the screw holder it is used at the same time as a clamping screw to tightly fix the second frame part 214 to the first frame part 212.

As can be seen from FIGS. 1 to 5, a step 304 is configured in a corner area 302 of the surrounding frame 210, configured on the opposite side of the hinge, the first step flank 306 of which is configured through the first partial frame bar 236, and whose second step flank 308 is configured through the second partial frame bar 288. Because the clamping connection 216 is configured at the base of a step 304, an attractive design can be achieved, and the surrounding frame 210 cannot be seen from the outside, since it is a frame with an adjustable mouth width .

With the feedback device 218 shown here, and the surrounding frame 210 with which it is provided, a visually appealing surround frame 210, with an adjustable mouth width M, can be achieved with simple constructive measures, using a part strategy. common, and using many of the same pieces as for the other frames, which does not require subsequent mortar work, and thus can be clamped dry, yet satisfies all requirements, especially in terms of strength for fire door frames .

Especially, the first frame part 212 can also be used alone as a corner frame. The support brackets 228, 230 used in this rest directly on the profile areas 240, 243 of the first part 212 of the frame, so that only a few pieces are required for feedback. At the same time, through these supports 228, 230 a clamping connection can be made for the accommodation, in a sliding manner, of the second part 214 of the frame, which acts as a counter frame.
