Description

The invention relates to a frame according to the preamble of the appended claim 1, such as it is known from EP 0 940 550 A2. Moreover, the invention relates to such Frame provided door and a method for mounting the frame or door.

In EP 0 940 550 A2, the Zargenstäbe to be arranged horizontally Predetermined breaking points divisible into two partial elements. The connection of the partial elements with the lateral Zargenstäben done by partly bent tabs, which are connected to the Part are spot-welded. This can be done by cutting the tabs and breaking the predetermined breaking points - these are preferably also welded joints - adjust the frame to local conditions, in particular the respective lower Adjust the frame rod to determine if a door sill should be present or not. The well-known Frame is for 180 ° turnable fire doors with optional right / left stop particularly suitable.

EP 0 805 255 B1 discloses a further frame for such a fire protection turning door. There, the vertical opening width of the frame is greater than the total height of the frame Door leaf including upper and lower door rabbets. It is an additional subelement provided for screwing to the upper horizontally arranged Zargenstab, that closes the resulting gap. The additional part is with spacers for Creating a distance between the supporting upper Zargenstab and at the Additional part formed upper visible surface of the Zargenrahmens and to reduce the upper Door gap thereby provided. About it, like the carrying upper Zargenstab with The side frame bars is connected, nothing is stated, therefore, the beginning EP 0 940 550 A2, which deals with this, as the closest prior art viewed. Since the sides of fire doors have to absorb high lateral forces - Fire test -, were used in the prior art welds to the corner joint.

Starting from the prior art according to EP 0 940 550 A2 it is the object of the invention is to form a frame with the characteristics of the generic term so that they even easier to adapt to structural conditions.

This object is achieved by a frame with the features of 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 invention thus provides a frame for a door, with several Zargenstäben, the Zargenecken are interconnected, wherein at least a first horizontally to be arranged Zargenstab two releasably connected or connectable sub-elements having. If according to the invention a releasable corner connection device for connecting two Zargenstäbe, then can be decided individually at the place of construction, whether a more or less high threshold may be present or not and the frame accordingly easily adapted.

A simpler construction results, albeit the two sub-elements of the horizontal to be arranged Zargenstabes means of Eckverbindungsvorrichtung releasably to each other connected or connectable.

The corner connecting device preferably has a corner connecting angle with a first tab for releasably securing the horizontally arranged Zargenstabes and two fasteners, 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 with the first Strap connects. This leaves when removing the one sub-element of the horizontal to be arranged Zargenstabes, the removal by simply loosening the first Fastener happens, the other sub-element via the second fastener firmly with the connected side frame rod; the frame remains a four-sided closed frame with appropriate stability, so that also a preassembled door leaf in this unscrewing step does not need to be removed. The remaining subelement does not need More to be fixed again and may possibly by re-attaching the first fastener be fixed even tighter. Advantageously, screws are used as fasteners, so that Zargenstäbe are connected by a screw connection over corner.

Wherein the corner connecting angle is preferably a helix angle, which connects to both over Eck abutting Zargenstäben is screwed.

If the corner connecting angle has a second tab, the (only) one fastener opening for receiving a third fastener for fixing a vertically arranged one Zargenstabes, then can also be by means of the first and second Fix multiple entire horizontal frame rod attached to corner joint bracket by simply loosening only one fastener per Zargenecke solve. If Moreover, a rotation is provided, which - especially when using the third fastener - a relative turning of the vertically arranged Zargenstabes and prevents the second tab, then despite the easy to solve and to be mounted Attachment created a sufficiently stable corner joint device, which also In case of fire occurring huge tension forces, the cause of temperature differences and even heavy steel constructions could bend holds. The anti-rotation device preferably has a projection on one of the two here connecting parts - second tab and vertically arranged Zargenstab - and a Receiving opening on the other part for the positive reception of the projection, because such a positive connection when assembling the parts is easy to produce and with appropriate design of projection and receiving opening also the Merging by a self-centering effect can greatly simplify.

The rigidity of the Zargenecke created by the Eckverbindungsvorrichtung can, without a visually and production (cost) moderately disadvantageous excessively thick connection angle to be used, further increased when the corner joint angle in the region of its angled stiffening device, in particular a transverse to the bend running, formed by a bend stiffening bead or a stiffening strut, has. Preferably then at least one of the two has the corner connecting angle to be connected Zargenstäbe at its front edge region a recess for positive reception of the in the corner of the connection angle protruding stiffening device. Further preferred are the stiffening device and the receiving recess receiving this conically widening / tapering complementarily formed, so that a self-centering effect arises during assembly. An additional attachment and thus stiffening the Zargenecke in addition to the fastener engagement is achieved by the corner joint device in the at or with the corner joint device parts to be connected fastener openings for Receiving fasteners such that edge regions of the fastener openings two parts to be joined together are in positive engagement with each other. One Centering effect is also achieved here when the edge region of a fastener opening one of the two to be connected at or with the Eckverbindungsvorrichtung parts tapering hollow towards the opening and the other edge region of the associated attachment opening the other part according to the opening tapering protruding is trained. This can be realized simply by virtue of the edge regions of the fastener openings are formed according to each other by deep drawing. Due to the positive locking Interventions of the borders at a right angle to each other over corner arranged Fittings, it is sufficient for a frame of a fire door from that the corner joint device thread-cutting or thread-forming screws having their threads formed on correspondingly shaped fastener openings themselves, so that the screw connections are quite easy to manufacture and solvable. additionally can advantageously still a tab engagement (21) for stabilizing between the Connected to corner frame rods and / or engagement between a projection one Zargenstab and a corresponding return to the other Zargenstab be provided. For this purpose, at least one of the two corner connected Zargenstäbe a profile with two are substantially parallel with distance to each other have extending profile areas. A first of these profile areas will be on a first Page engaged by a protruding from the other Zargenstab tab. Of the other profile area lies with one of the first side oppositely directed second Side rests on surface area of the other Zargenstabes, which is parallel to the tab As a result, the one Zargenstab is taken by the other in the pliers, so that the Zargenstäbe relatively movable only parallel to the extension of the tab are. The tab may be from a projecting profile area of the other Zargenstabes out of cranked, leaving the profile area as a stop for the first Zargenstab acts, and the Zargenstäbe further limited in their relative movement to each other are. Each remaining degree of freedom can then by a releasable fastener of Corner connecting device are releasably fixed. This makes it possible, despite the simple Mounting by means of screw one against twisting forces extremely robust and therefore particularly suitable for fire doors suitable frame create.

If both horizontally arranged Zargenstäbe are formed in several parts and / or are mirror images of each other and / or identical to each other, it is easier Manufacturability the possibility of using the frame in a turning door or created as a turning frame. It is preferable that also the Zargenstäbe to be arranged vertically or the entire frame mirror-symmetrical to a horizontal Zargenmittelebene are formed. If the frame bars to be arranged vertically are both at least a trap receiving opening and receiving means for receiving door hinges have, then opens up a common part strategy and / or the use the frame for optional right / left stop without turning the frame.

If the frame bars to be arranged vertically in a receiving groove with a strip made of foaming material in case of fire, is also suitable for higher Fire protection classes (T90, T120) without any special optical losses. special Advantage for the appearance of the frame, it has, if the strips are not up to the Zargenecken range, wherein in the remaining space of the receiving groove a part of the Eckverbindungsvorrichtung, in particular a tab of the connection angle, arranged is. As a result, the tab can be arranged on the visible side of the frame without optical attracting attention.

In the following, the basic structure of an embodiment will first be described with reference to FIGS. 15 to 20 a fire door 1 explained, then with reference to FIGS. 8 to 14 of Basic structure of a frame 5 used therein explained, and then starting with FIG. 1 describes the frame construction in detail.

The door 1 shown in FIGS. 14 to 20 has a cover sheet 2 and box 3 formed Door leaf 4 in fire protection version and a frame 5 in fire protection design 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 be easily Change the direction of the stop from left stop to right stop or vice versa.

The frame 5 is formed of four Zargenholmen or Zargenstäben 6a, 6b via corner connecting devices 7 are connected to each other. To be arranged vertically or laterally Zargenstäbe 6a come a lock rod 8, the center of a trap opening. 9 for the case 23 of a lock 24 of the door leaf 4 is provided, and a band bar 10th with two height-adjustable door hinges 11 are used. Horizontally arranged frame rods 6b are formed by a head bar 12a and a foot bar 12b, wherein the Head bar and the foot bar 12a, 12b are constructed substantially identical. The structure the door hinges 11 is in the co-pending German patent applications DE 103 35 349.6 and DE 103 16 891.5 exactly described and shown, which hereby to avoid is referenced by repetitions. With these height-adjustable door hinges You can also make a height adjustment of the door panel after turning the door 1.

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

Figs. 8 to 14 show the frame 5 without the door leaf 4. As can be seen from the horizontal frame rods 6b divided in their longitudinal direction; they are made of two subelements constructed in the form of angle-shaped sheet steel profiles 13 and 14, namely a frame angle 13 and an optionally used change angle 14th

The corner joint device 7 is similar in purpose to the corner joint device, which is described in EP 0 940 550 A2, to which expressly referred becomes. The functions of the Eckverbindungsvorrichtung known from EP 0 940 550 A2 are also met by the corner connecting device 7. Only this happens even easier and easy to assemble, because instead of a welded joint a screw connection 15 is used.

For this purpose, the corner connecting device 7 a Eckverbindungswinkel in the form of a Schraubwinkels 16, which is provided with screw holes 17, 17 a, 17 b, which in turn of recessed, in particular deep-drawn opening edge regions 18, 18 a, 18 b, here Conically shaped, are surrounded. In the frame rods to be joined together 6a, 6b are corresponding screw holes 27, 27a, 27b mounted therein, respectively suitable for the helix angle 16 recesses in the form of further conical Opening edge portions 19, 19a, 19b, 19c also formed by deep drawing, provided, into which the opening edge regions 18, 18 a, 18 b of the helix angle 16 form fit can intervene.

The screw 15 further has per Eckverbindungsvorrichtung 7 more, here three self-tapping screws or thread-forming screws 20, 20a, 20b. These are provided here with countersunk heads, which in the recessed opening edge areas 18, 18a, 18b and 19, 19a, 19b fit.

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

The frame 5 described here, depending on the circumstances at the site completely preassembled or with the occasional Zargenstäben 6a, 6b supplied.

The screw 15 not only attached to the horizontally arranged Zargenstäbe 6b to the lock rod 8 or band bar 10 (see FIG. 13), but also the two sub-elements 13, 14 of the respective horizontal Zargenstabes 6b, 12a, 12b to each other (see see FIGS. 11 to 14, in particular 13). The subarea - first tab 25 - of Schraubwinkels 16, which is to be attached to the foot or head bar 12a, 12b, this is with a first 17 and a second 17a of the angle-side screw holes 17, 17a, 17b Mistake. One of the two sub-elements 13, 14, namely here preferably the angle of change 14, is only with a first conical recessed screw hole 27 for receiving the first screw 20, while the other sub-element, the first screw hole 27th and the second screw holes 27a. So you can alone by solving the first both sub-elements 13, 14 by cross-screws 20 fastening the change angle 14 from the frame angle 13, while the frame angle through the second Screw 20a remains attached to the vertical Zargenstäben.

As shown in FIG. 10, a central screw connection 15a is also provided which only for detachable connection of the two sub-elements 13, 14 of the horizontal to be arranged Frame bars 6b and not to the corner joint of the same to the two vertically arranged Zargenstäbe 6a serves.

The basic structure of the frame 5 can be seen from the previously explained FIGS. 8 to 14. details and installation examples are shown in Figs. 1 to 7, to which in the following closer will be received. Depending on whether a more or less high threshold is available should be or not, the angle bracket 14 is screwed (left) - installation example As shown in FIG. 2 - or removed - installation example Fig. 2 - or the foot bar 12 b completely removed (not shown in detail).

Fig. 1 shows an example in which between the spaces to be closed by the door there is no or no ground level or should be. In this case, done an installation of the frame 5 without lower change angle 14. The Fußstab 12 is then only formed by the frame angle 13, which further for a very high stability of the frame frame provides.

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 portion 30 has a on even bent-back edge region 29, which acts reinforcing and unsightly or possibly brings sharp edges from the field of view and visibility. The first Stop area 30 merges into a U-profile area 31, which is used for profile stabilization serves and for receiving a door seal 28 (shown in Fig. 18, 19) is available, therefore the U-leg 32 opposite the first stopper area for forming a engageable supernatant Z-shaped. This is followed by a profile web area 34 on. The profile land area has the first and the second by deep drawing produced conical opening edge portion 19, 19a, which in low, in the longitudinal direction the foot bar 12 extending distance are arranged side by side. At the profile web area 34 is still followed by a peripheral bend 35 at. The bend 35 has approximately the same extent at the bottom as the U-profile area 31. The U-profile region 31 and the peripheral bend 35 form such a good base for supporting the frame 5 on the ground (OFF).

As a lateral Zargenstab 6a here is the band 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 rod 8 for manufacturing reasons substantially are constructed identically; on the lock bar 8 are only the door hinges 11th omitted.

The two frame bars 6a to be arranged vertically are very similar to the basic construction to the frame angle 13, so that for corresponding profile areas the same Reference numerals, supplemented "with a" are used and to explain the vertically arranged Zargenstäbe can be referenced to the above detailed description. 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 again to a bend 36a, which then at a distance parallel to the Profile web area 34a extends. The profile web portion 34a of the vertically arranged Zargenstäbe 6a is also provided with a receiving groove 38. There is a fire protection strip 39 glued from foaming in case of fire material. The fire protection strip 39 consistently occupies most of the receiving groove 38; in the end areas However, the Zargenecke is adjacent to the fire protection strip 39, the second tab 40 of the screw 16 is received in the receiving groove 38. The second tab 40 is the appearance (contour, width, thickness, color) of the appearance of the fire strip 39 adjusted.

The profile web portion 34a of the band bar 10 and lock rod 8 also has a larger one Extension in the direction of the door thickness than the profile web portion 34 of the frame angle 13, so that the bend 35a of the side bars 8, 10 around at least one of the Sheet thickness of the change angle 14 corresponding distance further protrudes 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 above Door fold 41 (see, e.g., Fig. 19).

The first stop portion 30 of the frame angle 13 does not reach to the ends, but is to form a close receptacle 42 of the abutting first abutment area 30a of the horizontally arranged Zargenstabes 8, 10 cut out, see also Fig. 6, which shows the Zargenecke from behind. With the front side 43 of the first stop area 30a, the horizontally arranged Zargenstab 8, 10 is supported on the Frame angle 13 from.

At the peripheral edge 53 of the profile web portion 34 of the frame angle 13 is also a here arcuate recess 46 for the positive reception of a on the Screw 16 arranged arranged, also rounded trained projection 52. The engagement between the recess 46 and the projection 52 acts during Screwing on the frame angle - like the interventions between the opening edge areas 18, 19, 18a, 19a, 18b, 19b self-centering. In addition, the form-fitting offer Interventions a firm assurance against Relatiwersetzung the with the Eckverbindungsvorrichtung 7 connected parts. This is especially in case of fire due to temperature differences occurring strong distortion forces advantageous.

Figs. 2 to 6 show an example of installation of the frame 5 with changing angle 14, for example a step between the rooms separated by the door 1 (not shown) cover or form.

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

The first profile leg 44 lies closely on the profile web portion 34 of the frame angle thirteenth on. He covers the second screw 20a, which is further away from the corner is as the first screw 20. He is also in an appropriate place like that Frame angle with one of the first screw opening 27 corresponding fourth screw opening 27c with a corresponding fourth conical deep-drawn opening edge region 19c provided. This engages positively in the closer to the corner first opening edge region 19 on the profile web portion 34 of the frame angle 13 a. The first screw 20 connects the change angle 14 with the frame angle 13 and with the first tab 25 of the screw 16.

The first profile leg 44 has further at one of the recess 46 corresponding point at its peripheral edge 54 an arcuate recess 46a for receiving the projection 52 at the screw 16.

The second profile leg 45 is located on the peripheral bend 35 of the frame angle 13 on. Its visible side 47 is flush with the visible side 48 of the peripheral bend 35a of the vertically arranged Zargenstabes 8, 10. An upper part of the second profile leg 45 stops with the peripheral edge 54 of the first profile leg 44. A remaining one lower part is in the longitudinal direction beyond the peripheral edge 54 in the form of a flag 49 continued, extending from the through the bottom of the U-profile portion 31 and the Bottom edge of the edge bend 35 defined floor level (OFF) from down to the bottom End edge 55 of the second profile leg 45 down and to the side below the Bend 35a flush with this extends. Extends upwards from the flag 49 of a tab 50, the bent to the flag 49 integral with this is formed and the back 51 of the bend 35 a this engages behind. By the tab engagement 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 corner abutting Zargenstäbe 6a, 6b limited. The remaining degrees of freedom are provided by the screw connection 15 removably eliminated.

In the following, the helix angle 16 is explained in more detail with reference to FIG. 7. The first, the Head / Fußstab 12 associated tab 25 is conical with the first and the second deep-drawn edged 18, 18 a threaded opening 17, 17 a provided. The second one is vertical only one, namely the third conically edged 18b screw holes 17b. Next is the lead of the above-mentioned projection-return engagement 26 on the second tab 40 in shape a depression (deep drawing) 51 is formed. The projection-return engagement 26 forms an anti-rotation to prevent relative rotation of Zargenstab 8, 10th and helix angle 16. A Umbiegungsbereich 57 between the two tabs 25, 40th is reinforced with a stiffener 58. This is essentially a deep-drawn stiffening bead 59 (Fig. 6) formed. By deep drawing forms the Stiffener bead 59 on its back inside the helix corner corner the lug 52 (Fig. 7), in the recesses 46, 46 a of the horizontally arranged Zargenstabes 6b positively engages.

In the horizontal Zargenstäben 6b are in the embodiment no fire protection strip provided, For the horizontally arranged end broadsides have 60th the door leaf 4 comparable fire protection strips 61 from foaming in case of fire Material. The sub-elements 13, 14 of the horizontal Zargenstäbe 6b are above and below each constructed identically. When using the change angle 14 so are the horizontal Frame rods 6b, i. Head bar 12a and foot bar 12b are identical in total, so that the representation of Figs. 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 delivered with pre-assembled door leaf 4. At the installation site can then be decided whether the use of left or Right stop with or without change angle to take place. If you do not want to create a step below, becomes horizontal at the bottom according to the selected stop type Zargenstab 6b - foot bar 12b - the change angle 14 away. This can be done by Loosening only two screws, namely the first screws 20 happen to be after the removal of the change angle 14 back into the frame angle 13 and screw angle 16 can be screwed. If no threshold is to be present, the complete foot bar 12b removed, which in turn is achieved by loosening only two screws 20b, namely the third screw 20c, the screw 16 with the band bar 10 and connect the lock rod 8 can be done.

In the second variant, the side bars 6a, 8, 10 and the preassembled horizontal bars 6b, 12a, 12b delivered with pre-assembled helix 16 isolated and at the Site screwed together, again per Zargenecke only one screw (third screw 20c) must be screwed. The tightening torque of the thread-forming countersunk screws 20, 20a, 20c is at assembly or factory pre-assembly to about 4.5 Nm ± 20%. This moment includes the thread moment of about 2 up to 3 Nm.
