Description

The invention relates to a Wendezarge according to the preamble of the appended claim 1, as known from EP 0 805 255 B1 is known. In addition, the invention relates to a door provided with such a frame and a method for mounting the frame.

From the GB 2 126 636 A is a kit for joining a conventional door without fire protection and no turning function known. This door has a frame with two vertically arranged Zargenstäben and two horizontally arranged Zargestäben, which are connected to Zargenecken or connectable. At least one horizontally arranged Zargenstab is divided in its longitudinal direction into at least two releasably connected together sub-elements. It is provided a releasable corner connection device, which connects at each Zargenecke a vertically arranged Zargenstab with a horizontally arranged Zargenstab via a screw detachably. To form a top horizontal bar to be arranged a simple one-piece rail, connected by helical angle with the vertically arranged Zargenstäben. A lower horizontally arranged Zargenstab consists of another simple rail a threshold insert and a drainage rail. Only the rail of the lower vertical Zargenstabes can be connected with screw angles with the vertically arranged Zargenstäben. How to connect the threshold insert and the drainage rail to the rail is left open.

The DE 40 06 691 C2 relates to a Stahlturzarge with two vertically arranged Zargenstäben and a lower horizontally arranged Zargenstab, which is connected via support plates releasably connected to the vertically arranged Zargenstäben. The lower horizontally arranged Zargenstab is bolted to the welded to the vertically arranged Zargenstäbe support plates. An upper horizontally arranged Zargenstab is not addressed. The formation of the lower horizontally arranged Zargenstabes is left open.

From the DE 197 32 938 C1 is a comparable construction as in the just mentioned DE 40 06 691 C2 available. The from the DE 197 32 938 C1 known construction is further formed by the fact that the support plate with which a Zargenecke a vertically arranged Zargenstab is connected to a horizontally arranged Zargenstab is no longer welded, but is releasably secured.

The DE 90 03 276 U1 relates to a steel frame which is formed from sections of a profile and discloses for the skilled person a frame with two vertically arranged and two horizontally arranged identical Zargenstäben. Each profile section, which each forms a Zargenstab, has a longitudinal groove in which a strip of foaming in case of fire material is housed.

The DE 91 124 67 U1 relates to a frame with vertically arranged Zargenstäben and horizontally arranged Zargenstäben wooden, which are connected to each other via a detachable screw connection. A suitability for a fire door or a suitability as Wendezarge is not apparent.

From the EP 0 940 550 A2 On the other hand, a turning frame for a fire door is known. In this Wendezarge the horizontally arranged Zargenstäbe are split at predetermined breaking points in two sub-elements. The connection of the sub-elements with the lateral frame rods is carried out by partially bent tabs which are spot-welded to the part to be joined. As a result, by cutting the tabs and breaking the predetermined breaking points - these are preferably welded joints - adjust the frame to local conditions, in particular the respective lower Zargenstab adapt to whether a door sill should be present or not. The known frame is particularly suitable for 180 ° reversible fire doors with optional right / left stop.

From the above-mentioned EP 0 805 255 B1 is disclosed another frame for such a fire-resistant turnstile. There, the vertical opening width of the frame is greater than the entire height of the door leaf including upper and lower door rabbets. There is provided an additional sub-element for screwing to the upper horizontally arranged Zargenstab, which closes the resulting gap. The attachment is provided with spacers for providing a distance between the supporting upper frame member and the upper visible surface of the frame frame formed on the attachment, and for reducing the upper door gap therethrough. About how the supporting upper Zargenstab is connected to the lateral Zargenstäben, nothing is said. Since the frames must absorb high transverse forces in fire doors - fire test -, were used in the prior art welding to the corner joint.

Based on the state of the art according to the EP 0 805 255 B1 It is an object of the invention to form a frame with the features of the preamble so that it is even more easily adaptable to structural conditions.

These The object is achieved by a frame with the features of the independent claim 1 solved.

advantageous Uses of the invention are the subject of the dependent claims and advantageous embodiments of the invention are the subject of the dependent claims.

The The invention thus provides a Wendezarge for a fire door, with several Zargenstäben, which are connected or connectable to Zargenecken, wherein at least one first horizontally arranged Zargenstab two releasably connected together or connectable sub-elements. According to the invention is a releasable Corner connecting device for connecting two Zargenstäbe provided. Therefore, at the place of construction can be decided individually, whether one more or less high threshold may or may not be present, and the frame may accordingly easily adapted.

Both are according to the invention horizontally arranged Zargenstäbe by a division in the longitudinal direction formed in several parts and mirror images of each other and / or identical formed to each other. As a result, with ease of manufacture the possibility the use of the frame in a turning door or created as a turning frame.

A simpler construction results according to the invention by that the two sub-elements of the horizontally arranged Zargenstäbe means the corner connecting device detachable interconnected or connectable.

The Corner connecting device has a Eckverbindungswinkel with a first tab for releasable Attach the horizontal bar and two fasteners on, of which a second fastener only one of the two sub-elements and a first fastener both sub-elements or only the other sub-element connects to the first tab. This leaves when you remove the a sub-element of the horizontally arranged Zargenstabes, wherein removal by simply loosening the first fastener is done, the other sub-element on the second fastener firmly connected to the union rod Zargenstab since; the frame remains a four-sided closed frame with appropriate Stability, so that also a pre-assembled door leaf at this unscrewing need not be removed. The remaining one Part element does not need to be fixed again and can possibly by re-attaching the first fastener even firmer be fixed. According to the invention are screw fasteners used as a fastener, so that Zargenstäbe by a screw connection over corner are connected.

Of the Eckverbindungswinkel is preferably a helical angle, the both over Corner abutting Zargenstäben can be screwed.

If the corner connecting angle has a second tab which (only) a fastener opening for receiving a third fastener for securing a vertical has to be arranged Zargenstabes, then can also be by means of first and second fasteners multiply to the corner connecting angle fastened entire horizontal frame rod by simply loosening only one fastener per Zargenecke solve. If, in addition, an anti-rotation is provided, the - especially at Use of the third fastener - a relative twisting of the vertically arranged Zargenstabes and the second tab prevents then, despite the easy to solve and mounting to be mounted a sufficiently stable corner joint device created, even in case of fire occurring huge tension forces, the their cause in temperature differences and have even heavy steel structures can bend, stops. The Anti-rotation preferably has a projection on one of the two Parts to be connected here - second Tab and vertically arranged Zargenstab - and a receiving opening on the other part to the form-fitting Recording the projection, because such a positive connection when joining the Parts is easy to produce and with appropriate design of projection and receiving opening Furthermore the joining together can greatly simplify by a self-centering effect.

The rigidity of the Zargenecke created by the Eckverbindungsvorrichtung can, without having to use a visually and manufacture (moderately disadvantageous) excessively thick connection angle, be further increased if the Eckverbindungswinkel in the region of its bending a stiffening device, in particular a transverse to the angled, by a Inflection formed stiffening bead or a stiffening strut, has. Preferably, at least one of the two frame bars to be connected to the corner connection angle has at its front edge area a recess for the positive reception of the stiffening device projecting in the corner of the connection angle. More preferably, the stiffening device and the recess receiving this are complementarily conically widening / tapering, so that a self-centering effect is produced during assembly. An additional attachment and thus stiffening of the Zargenecke in addition to the fastening engagement is achieved, the Eckverbindungsvorrichtung in the parts to be joined at or with the Eckverbindungsvorrichtung fastener openings for receiving fasteners such that edge regions of the fastener openings two with Parts to be joined are in positive engagement with each other. A centering effect is also achieved here when the edge region of a fastener opening on one of the two parts to be connected at or with the corner joint device is tapered hollow towards the opening and the other edge region of the associated fastening opening of the other part is tapered and protruding towards the opening. This can be realized simply by forming the edge regions of the fastener openings corresponding to one another by deep drawing. Due to the interlocking interventions of the boundaries at right angles to each other over Eckschraubungen arranged it is sufficient for a frame of a fire door, that the Eckverbindungsvorrichtung has thread-cutting or thread-forming screws that form their own thread to appropriately shaped fastener openings itself, so that the screw easily can be produced and solvable. In addition, advantageously still a tab engagement for stabilizing between the corner connected Zargenstäben and / or an engagement between a projection on the one Zargenstab and a corresponding recess on the other Zargenstab be provided. For this purpose, at least one of the two corner bars connected Zargenstäbe have a profile with two substantially parallel spaced apart extending profile areas. A first of these profile areas is engaged behind on a first side by a protruding from the other Zargenstab tab. The other profile area lies with a second side opposite the first side on surface area of the other Zargenstabes rests, which runs parallel to the tab Thus, the one Zargenstab is taken by the other in the pliers, so that the Zargenstäbe only parallel to the extension of the tab are relatively movable. The tab can extend from a projecting profile region of the other Zargenstabes cranked, so that the profile region acts as a stop for the first Zargenstab, and the Zargenstäbe are further limited in their relative movement to each other. Each remaining degree of freedom can then be releasably fixed by a releasable fastener of the corner connecting device. As a result, despite the ease of mounting by means of screw connections, it is possible to create a frame which is extremely insensitive to torsional forces and thus particularly suitable for fire doors.

Prefers are also the vertically arranged Zargenstäbe or the entire frame mirror-symmetrical formed to a horizontal Zargenmittelebene. When the verti kal to be arranged Zargenstäbe both at least one trap receiving opening and receiving means for receiving door hinges, then opened a common part strategy and / or the use of the frame for optional Right / left stop without Turn the frame.

If the vertically arranged Zargenstäbe in a receiving groove with a strip of foaming in case of fire material is provided aptitude for too higher Fire protection classes (T90, T120) without any special optical losses. Special advantage for The optics of the frame is, if the stripes do not reach to the Zargenecken, wherein in the remaining space of the receiving groove, a part of the Eckverbindungsvorrichtung, in particular a tab of the connection angle, is arranged. This can the tab can be arranged on the visible side of the frame without optical attracting attention.

The following is first based on the 15 to 20 the basic structure of an embodiment of a fire door 1 explained, then is based on the 8th to 14 the basic structure of a frame used therein 5 explained, and then starting with 1 the frame construction described in detail.

The in the 14 to 20 shown door 1 has a cover sheet 2 and box 3 formed door leaf 4 in fire protection as well as a frame 5 in fire protection version made of steel.

The door 1 is designed as R / L door; by turning the door 1 with frame 5 and door leaf 4 around a perpendicular to the door plane center axis by 180 ° can easily achieve a change of the direction of the stop from left stop to right stop or vice versa.

The frame 5 is formed by four frame bars or frame bars 6a . 6b the over corner connecting devices 7 connected to each other. As vertical or lateral to be arranged Zargenstäbe 6a come a lock bar 8th , which is centered with a trap opening 9 for the trap 23 a castle 24 of the door leaf 4 is provided, and a ribbon bar 10 with two height-adjustable door hinges 11 for use. Horizontally arranged frame rods 6b are by a headstick 12a and a footstool 12b formed, with the head bar and the foot bar 12a . 12b are constructed essentially identical. The construction of the hinges 11 is in the co-pending German patent applications DE 103 35 349.6 such as DE 103 16 891.5 exactly described and shown, which is hereby referred to avoid repetition. With these height-adjustable door hinges you can also adjust the height of the door leaf after turning the door 1 make.

Central bulges of the door leaf 4 in case of fire by at least one safety pin 22 avoided or reduced, the door leaf 4 is screwed in and in a corresponding opening on the band bar - here also prepared on the band bar latch opening 9 - intervenes.

The 8th to 14 show the frame 5 without the door leaf 4 , As can be seen from the horizontal Zargenstäbe 6b divided in their longitudinal direction; they are made of two sub-elements in the form of angular steel sheet profiles 13 and 14 built, namely a frame angle 13 and an optionally used change angle 14 ,

The corner joint device 7 is similar in purpose to the Eckverbindungsvorrichtung, which in the EP 0 940 550 A2 which is expressly referred to. The functions of the EP 0 940 550 A2 Known corner joint device are also by the Eckverbindungsvorrichtung 7 Fulfills. Only this is done even easier and easier to assemble, because instead of a welded joint a screw 15 is used.

For this purpose, the corner connecting device 7 a corner connecting angle in the form of a screw angle 16 on, with screw holes 17 . 17a . 17b is provided, in turn, of recessed, especially deep-drawn opening edge areas 18 . 18a . 18b , cone-shaped here, are surrounded. In the frame rods to be joined together 6a . 6b are to appropriate screw holes in it 27 . 27a . 27b each matching the screw angle 16 Recesses in the form of further conical opening edge areas 19 . 19a . 19b . 19c also formed by deep drawing, provided in the opening edge areas 18 . 18a . 18b the screw angle 16 can intervene positively.

The screw connection 15 further points per corner joint device 7 several, here three self-tapping screws or thread-forming screws 20 . 20a . 20b on. These are provided here with countersunk heads, which in the recessed opening edge areas 18 . 18a . 18b and 19 . 19a . 19b fit.

The frame rods 6a . 6b are also still on tab interventions 21 , with the appropriate alignment of the Zargenstäbe 6a . 6b Match each other, fixed to each other. This will be explained in more detail below with reference to the corresponding drawings.

The frame described here 5 Can be completely pre-assembled depending on the circumstances at the site or with the occasional Zargenstäben 6a . 6b to be delivered.

The screw connection 15 not only fixes the horizontal bars to be arranged horizontally 6b to the lock bar 8th or ribbon bar 10 (please refer 13 ), but also the two sub-elements 13 . 14 of the respective horizontal Zargenstabes 6b . 12a . 12b to each other (see 11 to 14 , especially 13 ). The section - first tab 25 - the screw angle 16 , the foot or head bar 12a . 12b is to attach, this is with a first 17 and a second 17a the angle-side screw holes 17 . 17a . 17b Mistake. One of the two subelements 13 . 14 , namely here the angle of change preferred 14 , is only with a first conical recessed screw hole 27 for receiving the first screw 20 provided while the other sub-element, the first screw hole 27 and the second screw holes 27a having. So you can alone by solving the first two sub-elements 13 . 14 sweeping screws 20 the attachment of the change angle 14 from the frame angle 13 Loosen while the frame angle through the second screws 20a remains attached to the vertical Zargenstäben remains.

As 10 shows is also still a central screw connection 15a provided, only for releasable connection of the two sub-elements 13 . 14 the horizontally arranged Zargenstäbe 6b and not to the corner connection of the same to the two vertically arranged Zargenstäbe 6a serves.

The basic structure of the frame 5 is from the previously explained 8th to 14 seen. Details and installation examples are in the 1 to 7 shown in detail below. Depending on whether a more or less high threshold is to be present or not, the angle of change 14 screwed on (leave) - fitting example according to 2 - or removed - installation example 2 - or the footstool 12b completely removed (not shown in detail).

1 shows an example in which between the spaces to be closed by the door no step or no Bodeneinstand is or should be. In this case, the frame is installed 5 without lower exchange angle 14 , The footstool 12 is then only by the frame angle 13 formed, which continues to provide a very high stability of the frame frame.

The frame angle 13 is formed by a multi-bent steel profile strip. The profile of the same has a first stop area 30 as a stop for the box 3 of the door leaf 4 , The free edge of the first stop area 30 has a marginal area bent back on itself 29 on, which acts reinforcing and unsightly or even sharp edges from the field of vision and visibility. The first stop area 30 goes over into a U-profile area 31 , which serves for profile stabilization and for receiving a door seal 28 (shown in 18 . 19 ) is usable, which is why the first stop area opposite U-legs 32 designed to form a tangible supernatant Z-shaped. This is followed by a profile web area 34 at. The profile land area has the first and second conical opening edge areas made by deep drawing 19 . 19a which, in slight, extend longitudinally of the foot bar 12 extending distance are arranged side by side. To the profile web area 34 closes another edge bend 35 at. The bend 35 has at the bottom approximately the same extension downwards as the U-profile area 31 , The U-profile area 31 and the edge bend 35 thus form a good base for supporting the frame 5 on the ground (OFF).

As a lateral Zargenstab 6a here is the ribbon bar 10 with a frame-side part of the door hinge 11 shown. The representation is just as representative of the lock-side lower Zargenecke because ribbon bar 10 and lock bar 8th are essentially constructed identically for manufacturing reasons; at the lock bar 8th are just the door hinges 11 omitted.

The two vertical bars to be arranged vertically 6a are very similar to the basic structure of the frame angle 13 so that the same reference numerals, supplemented with "a" are used for corresponding profile areas and can be referred to the above detailed description to explain the vertically arranged Zargenstäbe The bend 35a in the vertically arranged Zargenstäben 6a but is longer than the edge bend 35 of the frame angle 13 , And it closes at the bend 35a once again a back bend 36a then, at a distance parallel to the profile web area 34a runs. The profile web area 34a the vertically arranged Zargenstäbe 6a is also with a receiving groove 38 Mistake. There is a fire protection strip 39 glued from foaming in case of fire material. The fire protection strip 39 Consists consistently the largest part of the receiving groove 38 ; in the end areas at the Zargenecke is adjacent to the fire protection strip 39 but the second tab 40 the screw angle 16 in the receiving groove 38 added. The second tab 40 is the appearance (contour, width, thickness, color) of the appearance of the fire strip 39 equalized.

The profile web area 34a of the ribbon bar 10 or lock rod 8th also has a greater extent in the direction of the door thickness than the profile web area 34 of the frame angle 13 so that the bend 35a the side bars 8th . 10 at least one of the sheet thickness of the changing angle 14 corresponding distance protrudes further than the edge-side bend 35 of the frame angle 13 , The bend 35a acts as a second stop area for the door leaf 4 namely for the opposite of the box 3 protruding door rebate 41 (see eg 19 ).

The first stop area 30 of the frame angle 13 is not enough to its ends, but is to form a close shot 42 the abutting first stop area 30a of the horizontally arranged Zargenstabes 8th . 10 cut out, see also 6 showing the corner from behind. With the front 43 the first stop area 30a supports the horizontally arranged Zargenstab 8th . 10 at the frame angle 13 from.

At the edge 53 of the profile web area 34 of the frame angle 13 is also an arcuate recess here 46 for positively receiving one at the helix angle 16 arranged, also rounded trained projection 52 intended. The engagement between the recess 46 and the lead 52 acts when screwing the frame angle - as the interventions between the opening edge areas 18 . 19 . 18a . 19a . 18b . 19b self-centering. In addition, the interlocking interventions provide a firm assurance against relative displacement of the corner joint device 7 connected parts. This is particularly advantageous in case of fire due to temperature differences strong distortion forces advantageous.

The 2 to 6 show an installation example of the frame 5 with change angle 14 for example, a step between those through the door 1 can cover or form separable rooms (not shown).

The change angle 14 is as a simple angle profile with two at a right angle to each other bent profile legs 44 and 45 educated.

The first profile leg 44 lies close to the profile web area 34 of the frame angle 13 on. He covers the second screw 20a farther away from the corner than the first screw 20 , He is also in an appropriate place as the frame angle with one of the first screw hole 27 corresponding fourth screw opening 27c with a corresponding fourth conical deep-drawn opening edge region 19c Mistake. This engages positively in the closer to the corner lying first opening edge area 19 at the profile web area 34 of the frame angle 13 one. The first screw 20 connects the change angle 14 with the frame angle 13 and with the ers th tab 25 the screw angle 16 ,

The first profile leg 44 has further on one of the recess 46 corresponding point on its edge 54 an arcuate recess 46a for receiving the projection 52 at the helix angle 16 ,

The second profile leg 45 lies on the edge bend 35 of the frame angle 13 on. His visual side 47 is flush with the visible side 48 the marginal bend 35a of the vertically arranged Zargenstabes 8th . 10 , An upper part of the second profile leg 45 hear the edge 54 of the first profile leg 44 on. A remaining lower part is longitudinally over the peripheral edge 54 out in the form of a flag 49 continued, extending from the through the bottom of the U-profile area 31 and the lower edge of the peripheral bend 35 defined floor level (OFF) down to the lower end edge 55 of the second profile leg 45 down and to the side under the bend 35a extending flush with this final. Upwards extends from the flag 49 from a tab 50 , which is bent to the flag 49 is integrally formed with this and the back 51 the bend 35a grasps these comprehensively. By the tab intervention 21 forming tab 50 and the stop between the bend 35 and the flag 49 and the detection of the first two stop areas 30 . 30a are relative movement possibilities of the abutting corner bars 6a . 6b limited. The remaining degrees of freedom are provided by the screw connection 15 solved solvable.

The following is based on the 7 the screw angle 16 explained in more detail. The first, the head / foot bar 12 associated tab 25 is bordered with the first and the second conical deep-drawn 18 . 18a screw opening 17 . 17a Mistake. The second, the frame bars to be arranged vertically 6a . 6b associated tab 40 has only one, namely the third conically edged 18b screw holes 17b , Further, the projection of the above-mentioned projection-recess engagement is 26 at the second tab 40 in the form of a statement (depression) 51 educated. The projection-return engagement 26 forms a rotation to prevent relative rotation of Zargenstab 8th . 10 and screw angle 16 , A bend area 57 between the two tabs 25 . 40 is with a stiffening device 58 strengthened. This is essentially a deep-drawn stiffening bead 59 ( 6 ) educated. By deep drawing forms the stiffening bead 59 on its back inside the helix corner the projection 52 ( 7 ), in the recesses 46 . 46a of the horizontally arranged Zargenstabes 6b positively engages.

In the horizontal frame rods 6b In the exemplary embodiment, no fire protection strips are provided, but have the horizontally arranged end broadsides 60 of the door leaf 4 comparable fire protection strips 61 from foaming in case of fire material. The subelements 13 . 14 the horizontal frame bars 6b are identically constructed above and below. When using the change angle 14 So are the horizontal Zargenstäbe 6b ie headstick 12a and footstool 12b altogether identical, so that the representation of the 2 and 6 is also representative of the two upper Zargenecken.

There are different variants for mounting. In a first variant, the complete frame 5 factory pre-assembled and with pre-assembled door leaf 4 be delivered. At the installation site it can then be decided whether the use should be made with a left or right stop with or without a change angle. If there is no step below, the horizontal frame will be used at the bottom according to the selected stop type 6b - Footstool 12b - the change angle 14 away. This can be done by loosening only two screws, namely the first screws 20 done after removing the change angle 14 again in the frame angle 13 and screw angle 16 can be screwed. If no door threshold is to be present, the complete footstool 12b removed, which in turn by loosening only two screws 20b namely the third screws 20c that the screw angle 16 with the ribbon bar 10 and the lock bar 8th connect can take place.

In the second variant, the side bars 6a . 8th . 10 and the pre-assembled horizontal bars 6b . 12a . 12b with pre-assembled helix angle 16 occasionally delivered and screwed together at the construction site, again only one screw per corner joint (third screw 20c ) must be screwed. The tightening torque of the thread-forming countersunk screws 20 . 20a . 20c is to be set to approx. 4.5 Nm ± 20% during assembly or factory pre-assembly. This moment includes the thread torque of approx. 2 to 3 Nm.
