Description

Door frame, in particular for a door swivel

The invention relates to a door frame according to the preamble of the attached claim 1, as known by EP 0 940 550 A2. The invention further relates to a door provided with such a framework, as well as a procedure to mount the frame or the door.

In the frames known from EP 0 940 550 A2, the bars can be divided, to be arranged horizontally, in two partial elements with breakpoints controlled. The union of the partial elements with the bars side of the frame is done, in part, by means of fins angled, which have been welded by points with the piece to be joined. Thanks to this, the framework can be adapted to the particularities premises, dividing the fins in two parts and breaking the points controlled breakage - these are also preferably joints by welding-, in particular, adapt the respective lower bar of the framework to whether or not a door threshold should be provided. The known frame is especially suitable for revolving fire doors 180º with discretionary right / left stop for the door.

By EP 0 805 255 B1, it has been published another frame for a revolving fire door similar. In said document, the vertical amplitude of the opening of the frame is greater than the entire height of the door leaf, including the upper and lower recesses. It is planned a additional partial element to fasten with screws to the bar top of the horizontally arranged frame, which closes the opening existing for that reason. The additional piece has been provided with spacers to produce a separation between the bar of the upper bearing frame and the visible upper surface of the frame frame formed in the additional part and to reduce, with it, the upper slit of the door. Nothing is exposed about how the top bearing frame bar is attached with the bars side of the frame, therefore, document EP 0 has been considered 940 055 A2 mentioned at the beginning, which deals with it, such as the closest state of the art. Since at the gates firewalls, the frames have to absorb high forces transversal -behavior test to fire-, were used in the state of the art welds for the union of corners

From WO 98 / 14681A, a three-sided frame with two side frame bars and one bar of upper frame to be arranged horizontally. All the bars of frame present two partial elements and still a third element partial. The first and second partial elements have been set mutually scrollable by means of devices special fixing with an elongated hole in one of the two partial elements in the direction of the thickness of the frame. Additionally there is a separable corner joint device between the lateral stringers of the frame and the upper stringer of the framework. In addition, a first element is fixed by screws partial from the sidebar of the frame to the first partial element of the top bar of the frame. It is also fixed by screws the second partial element of the sidebar of the frame at second partial element of the top bar of the frame. Due to the special fixing device to fix the partial elements First and second through an elongated hole, they can be fixed the two partial elements relatively movable between them main of all frame bars so that the opening The frame can be adapted to different wall thicknesses. Additionally, each frame bar still has a third element partial in the form of a tilting cover.

Starting from the state of the art according to the EP 0 940 550 A2, it is the mission of the invention to configure a frame for a revolving door, with the characteristics of the preamble, so that it can be adapted even more easily to the constructive peculiarities with regard to the threshold of the door.

This mission is fulfilled through a framework. with the characteristics of independent claim 1.

Advantageous uses of the invention are subject to secondary claims and advantageous configurations of the invention are subject to the dependent claims.

The invention therefore provides a framework for a revolving door with several frame bars, which are mutually joined in the corners of the frame, presenting at least a first horizontal bar of the frame, to be arranged horizontally, two partial elements united or separable separable from each other. According to the invention, a connecting device of Separable corners to join two frame bars. Therefore, it can decide individually on site whether or not to dispose of a more or less high door threshold, and adapt the frame easily accordingly.

It is a simpler construction because the two partial elements of the frame bar, to be arranged horizontally, join or join each other so separable by means of the corner joining device.

The corner joining device features preferably a corner joint angle with a first flap to detachably fix the frame bar, to be arranged horizontally, and two bras, of which a second bra only hold one of the two partial elements and a first bra joins both partial elements or only the other element partial with the first fin. Thanks to that, it is united solidly with the sidebar of the frame the other partial element by means of the second fastener, when removing one of the elements partials of the frame bar to be arranged horizontally, having place the suppression by simple release of the first fastener; he frame is forming a four-sided closed frame with the corresponding stability so that it also doesn't need to be suppressed a door leaf preassembled at this stage of screwed The remaining partial element does not need to be fixed anymore again and can eventually be fixed even more solidly by new application of the first bra. For convenience, they are used  screws as fasteners so that the frame bars are joined by a union screwed in the corner. At the same time, the corner joint angle is preferably an angular screwed, which can be fixed by screws to the bars of the butt frame in the corner.

When the corner joint angle has a second fin, which (only) has a fixing hole to receive a third fastener to fix a frame bar to arranged vertically, then it can also be released, by simple release of a bra only by frame corner, entire horizontal bar of the frame fixed several times to the angular corner joint by means of the first and second fasteners. When torsion protection is also provided, which prevents - especially when using the third fastener - a twist relative of the frame bar, to be arranged vertically, and the second fin, then a binding device of sufficiently stable corner despite the simple fixing of release and mount, which also resists torsional forces that they appear in case of fire, which have their cause in the temperature differences and that can double even solid steel constructions The torsion protection has preferably a shoulder in one of the two pieces to be spliced in this case -second fin and bar of the frame to be arranged vertically- and a reception opening in the other piece to receive in union positive form the highlight, because such positive form union is Easy to perform when assembling parts and can simplify also considerably the coupling by an effect of self-centering with proper shoulder and opening configuration reception.

The stiffness of the corner of the frame produced by the corner joint device can be further increased without having to use an exaggeratedly thick corner joint angle unfavorable to the eye and in terms of processing costs, when the corner joint angle has a corner reinforcement mechanism, especially a reinforcement brace or a reinforcement groove, which runs transversely to its bending, formed by a fold. At least one of the two bars of the frame, to join with the corner joint angle, has then preferably in its front edge area a recess to receive positively the reinforcement mechanism protruding in the corner of the joint angle. Still preferred more than the reinforcement mechanism and the recess, which receives it, it set widening / narrowing conically in addition so that there is an effect of self-centering during assembly. An additional fixation and, with this, a corner reinforcement of the additional frame to the lace of fixing is achieved by the corner joining device present fixing holes in the pieces to be joined in or with the corner joining device to receive fasteners in such a way that the edge areas of the two-piece fixing holes to join each other fit in positive union with each other. In this case, a centering effect is also achieved if the area of edge of a fixing hole, in one of the two pieces to join in or with the corner joining device, it is hollow narrowing towards the hole, and the other edge area of the corresponding fixing hole of the other part is configured protruding conveniently narrowing towards each other orifice. This can be done simply so that the edge areas of the fixing holes mutually conform conveniently by deep drawing. Due to couplings in positive connection of the edges with the screwed mutually arranged at right angles to the corner, it is also enough for a door frame of fire protection than corner joining device present self-locking or self-tapping screws, which conform themselves their thread in fixing holes conveniently molded so that screw connections are very simple of performing and releasing. You can still provide additionally advantageous a fin coupling for stabilization between the frame bars joined by the corner and / or a lace between a highlight on one of the frame bars and an entree corresponding in the other bar of the frame. To do this, at least one of the frame bars joined by the two corners can have a profile with two profiled areas, which extend so substantially parallel to each other. A first of those profiled areas are attacked from behind on a first face by a projecting fin of the other frame bar. The other zone profiled rests with a second opposite face oriented opposite to the first face in a superficial area of the other frame bar, which runs parallel to the fin. Thus, one of the frame bars is pressed by the other so that the frame bars are only relatively mobile in parallel to the fin extension. The fin can run in an angled manner from a profiled area protruding from the other bar of the frame of so that the profiled area acts as a stop for the first bar of the frame, and the bars of the frame are even more restricted in their mutual relative movement. Each remaining degree of freedom can then detachably fixed, by a releasable bra of the corner joining device. Thanks to that, you can make a extremely insensitive frame to torsional forces and, for this, especially good for a door of protection against fires, despite its simplicity of assembly by means of unions to screws

When the two bars of the frame, to arrange horizontally, they are configured of several pieces and / or configured symmetrically with respect to a plane and / or mutually identical, Then it can be established with simple manufacturing capacity the possibility of using the frame on a revolving door or as rotating frame It is preferred that also the frame bars, to arrange vertically, or the entire frame is symmetrically configured with respect to a central horizontal plane of the frame. When the frame bars, to be arranged vertically, present both to the minus one receiver hole for latch and receiver mechanisms to receive bolts, then a parts strategy is offered equal and / or use of the framework for discretionary cap to right / left without turning the frame.

When the frame bars, to dispose vertically, they are provided in a receiving slot of a strip  of foaming material in case of fire, there is also a suitability for fire protection degrees (T90, T120) higher without special optical deterioration. Has special advantage for the optical aspect of the frame that the strips do not reach to the corners of the frame, having arranged in space remaining part of the receiving slot a part of the joining device corner, especially a joint angle fin. Thanks to this, the fin can be arranged on the face of the frame without draw attention to its optical appearance.

Next, it is explained, first by means of Figures 15-20, the basic construction of an example of realization of a fire protection door 1, then explains by means of figures 8 to 14 the basic construction of a frame 5 used in it, and then the detail is described in detail frame construction starting with figure 1.

The door 1 shown in figures 14 to 20 It has a door leaf 4 formed by sheet 2 cover and box 3 in one embodiment of fire protection, as well as a 5 steel frame in fire protection realization of steel.

Door 1 has been configured as an R / L door (a right, left); turning door 1 180º with frame 5 and door leaf 4 around a central axis that is perpendicular in the plane of the door, a change can be achieved simply from the top direction, from top to left to top to right or vice versa.

The frame 5 is formed by four stringers of frame or bars 6a, 6b of frame, which are mutually joined by 7 corner joining devices. As frame bars 6a, to arranged vertically or laterally, a bar 8 of lock, which has been centrally provided with an opening 9 of latch for latch 23 of a lock 24 of sheet 4 of door, and a bar 10 of hinges with two bolts 11 adjustable in height. The bars 6b of the frame, to be arranged horizontally, are formed by a header bar 12a and a socket bar 12b, the bars 12a having been constructed basically identically, 12b header and socket. The construction of the pernios 11 se Describes and shows exactly in patent applications  German attached DE 103 35 349.6 and DE 103 16 891.5, to which Refer hereby to avoid repetitions. With these bolts adjustable in height, an adaptation can also be made in height of the door leaf after turning the door 1.

Bulging is avoided or lessened central door leaf 4, in case of fire, for at least a security bolt 22, which is screwed into the door leaf 4 and fits into a corresponding hole in the hinge bar - here the opening 9 of the latch also provided in the bar hinges-.

Figures 8 to 14 show frame 5 without leaf 4 door. As can be seen in them, bars 6b of Horizontal frames are divided longitudinally; they have constructed from two partial elements in the form of bars 13 and 14 of angular steel sheet, namely an angular 13 of frame and an alternative angle 14 usable at discretion.

The corner joint device 7 is comparable, from the point of view of its objective, to the device corner joint, which is described in EP 0 940 550 A2, which is expressly referred to. The device functions of corner joint known from EP 0 940 550 A2 se they also comply with the corner connection device 7. Though This occurs even more simply and with more pleasant assembly, since that, instead of a weld joint, a joint 15 is used by screw

For this, the corner joint device 7 presents a corner joint angle in the form of an angle 16 screwed, which is provided with holes 17, 17a, 17b for screws, which are, in turn, surrounded by zones 18, 18a, 18b of deepened hole edge, especially embedded in depth, in this case conically configured. On the bars 6a, 6b of the framework to join each other, are planned, around threaded holes 27, 27a, 27b conveniently practiced in they, coincidental concavities, in each case, with the angular 16 screwed in the form of zones 19, 19a, 19b of edge of holes, also made by deep drawing, in which the zones 18, 18a, 18b of angled hole 16 screwed edge can fit into positive union of form.

The screw connection 15 also presents each corner connection device 7 several screws, in this Case of three self-harvesters or self-tapping screws 20, 20a, 20b. They are provided with countersunk heads, which match within hole 18, 18a, 18b and 19, 19a, 19b deepened

In addition, the bars 6a, 6b of the frame are fixed mutually also by means of lace 21 of fins, which in case of proper orientation of the bars 6a, 6b of the frame agree each. This is explained in more detail below by The corresponding drawings.

The frame 5 described here can be preassembled completely according to the particularities in the place of employment or they can supply the bars 6a, 6b of the frame separately.

The union 15 by screws not only holds the bars 16a of the frame, to be arranged horizontally, to bar 8 of the lock or the bar 10 of the hinges (see figure 13), but also mutually holds the two elements 13, 14 partials of the respective bar 6b, 12a, 12b of the frame (see for it figures 11 to 14, especially figure 13). Area Partial -First fin 25- of angular 16 screwed, to be fix to the header bar 12a or the socket bar 12b, it has been provided, for this, with a first 17 and a second 17th of the threaded holes 17, 17a, 17b on the side of the angle. One of the two partial elements 13, 14, namely, in this case preferably the alternative angle 14 is only provided with a first hole 27 conically deepened thread to accommodate the first screw 20, while the other partial element presents the first threaded hole 27 and the second threaded hole 27a. So you can release, loosening only the first two screws 20 that penetrate in partial elements 13, 14, fixing angle 14 alternative of the angular 13 of the frame, while the angular of the frame remains secured by the second screws 20a at vertical frame bars.

As Figure 10 shows, it is planned by addition a central union 15a by screws, which only serves for the separable union of the two partial elements 13, 14 of the 6a bars of the frame, to be arranged horizontally, and not for joining corner thereof to the two bars 6b of the frame, to be arranged vertically

The basic construction of frame 5 can be observe from figures 8 to 14 explained above, which will be entered in more detail below. Depending on whether there must be a more or less high door threshold, Screw (left in place) the alternate angle 14 - example of assembly according to figure 2- or suppressed - assembly example according to Figure 1- or the socket bar 12b is completely suppressed (without represent in greater detail).

Figure 1 shows an example, in which, between the spaces that the door should close, does not exist or should not be step or floor stud. In this case, the frame assembly 5 without bottom 14 angular alternative. The bar Socket 12 is then formed only by angle 13 of the frame, which also ensures high stability of the frame of the frame.

The angular 13 of the frame is formed by a Profiled steel strip several times folded. Its profile it has a first stop zone 30 as a stop for box 3 of the door leaf 4. The free edge of the first buffer zone 30 it has an area 29 of the edge folded back on itself, acting reinforcing and away from the area of vision or detection ugly or possibly sharp cutting edges. The first zone 30 butt, a U-shaped area 31 becomes, which serves to stabilize the profile and that is usable to accommodate a board 28 watertight door (shown in figures 18, 19), so which the U-wing 32 opposite the first stop zone has been configured to form a Z-shaped projection, which attacks by behind. To said wing 32 a profile core zone 34 is juxtaposed. The profile core zone has edge areas 19, 19a of first and second conical hole made by drawing deep, that have been arranged next to each other within walking distance, extending longitudinally to the socket bar 12. In the zone 34 of the profile core is also added an edge fold 35. The fold has approximately the same extent as it has downwards the zone 31 profiled in U. The zone 31 profiled in U  U and the marginal fold 35 thus form a good basis to support the frame 5 on the ground (OFF).

As 6a sidebar of the frame, it is shown here the hinge bar 10 with a part of the bolt 11 on the side of the framework. But the representation is equally representative for the bottom frame corner of the lock side, since the hinge bar 10 and lock bar 8 have been constructed substantially identical for manufacturing reasons; in bar 8 lock, only bolts 11 have been removed.

The two bars 6a of the frame, to be arranged vertically, they are very similar, from the point of view of basic construction, to angular 13 of the frame so that, for the respective profile areas, the same have been used reference numbers completed with "a", and for the explanation of the frame bars, to be arranged vertically, is You can refer to the detailed description mentioned above. But fold 35a in the bars 6a of the frame, to be arranged vertically, is longer than the edge bend 35 of the angular 13 of the frame. Y a fold 36a is added back to the 35th fold again, which then runs parallel to the area 34a of the soul of the profile. Zone 34a of the soul of the profile of the bars 6a of the frame, to be arranged vertically, it is also provided with a slot 38 Receiver A protective strip 39 against the fire of foaming material in case of fire. The strip 39 protective against fire occupies, in general, most of the receiving slot 38; although in the extreme areas in the corner of frame, it has been received in the receiving slot 38 limiting with the strip 39 firewall, the second fin 40 of angular 16 screwed The second fin 40 is equal in appearance (contour, width, thickness, color) to the appearance of the strip 39 Firewall

Zone 34a of the profile core of the bar 10 of hinges or lock bar 8 also has a larger extension in the direction of the thickness of the door than zone 34 of the profile core of the angular 13 of the frame, so that the 35a fold of the side bars 8, 10 is more advanced, in al minus the length corresponding to the thickness of the angle plate 14 alternative, that the marginal 5a fold of angular 13 of the frame. The fold 35a acts as the second buffer zone for the blade 4 of the door, namely for the recess 41 outstanding respect of the door box 3 (see, for example, figure 19).

The first stop zone 30 of the angular 13 of the frame does not reach its ends, but is trimmed to form a narrow housing 42 of the 30th buffer zone, facing butt, of the bar 8, 10 of the frame to be arranged horizontally, see also figure 6, which shows behind the corner of the framework. The bar 8, 10 of the frame, to be arranged horizontally, is supports with the front face 43 of the first stop zone 30a in the angular 13 of the frame.

At the edge 53 of the edge of zone 34 of the soul of profile of the angular 13 of the frame, a recess 46, in this case arched, to receive in positive union so that a shoulder 52 also has a rounded shape, arranged in angular 16 screwed. The lace between the recess 46 and shoulder 52 acts self-centering when Screw the angle of the frame - like the fittings between the zones 18, 19, 18a, 19a, 18b, 19b orifice edge-. The lace in positive form union also offer a solid secure against relative displacement of the pieces connected with the device 7 of corner junction. This is especially advantageous with Remarkable deformation forces in case of fire, due to to temperature differences.

Figures 2 to 6 show an assembly example of the frame 5 with alternative angle 14, which, for example, can cover or form a step between the spaces (not shown) to separate by door 1.

The alternative angle 14 has been formed as simple angular profile with two wings 44 and 45 mutually profiled angled forming a right angle.

The first wing 44 of the profile is tightly on zone 34 of the profile core of the angular 13 of the frame. It also covers the second screw 20a, which has been arranged more far from the corner than the first screw 20. It is also provided with a fourth threaded hole 27c, corresponding to the first threaded hole 27, with a respective fourth zone 19c conical hole edge made by deep drawing in a Convenient place as the angle of the frame. Said zone 19c of hole edge fits positively together in the first hole edge zone 19, which is closer to the corner in the area 34 of the profile core of the angular 13 of the frame.

The first wing 44 of the profile also has, in a place corresponding to the recess 46 of its edge edge 54, an arcuate recess 46a to receive the shoulder 52 of the angle 16 screwed.

The second wing 45 of the profile rests on the fold 35 of the edge of the angular 13 of the frame. His face 47 view it is flush with the face 48 view of the 35th edge fold of the bar 8, 10 of the frame to be arranged vertically. A top of the second wing 45 of the profile ends with the edge 54 of the edge of the first wing 44 of the profile. A remaining bottom continues longitudinally on the edge 54 of the edge in the form of a 49 skirt, which extends closing from the ground level (OFF), defined by the underside of profile area 31 a U and the lower edge of the edge fold 35, until the end edge 55 bottom of the second wing 45 of the profile down and laterally under the 35th fold flush with it. From skirt 49 towards a flap 50 is extended above, which has been configured towards skirt 49 and one piece with it and attacks from behind the back side 51 of the fold 35a encompassing it. Thanks to fin 50, which forms the flap 21, and at the top between the fold 35 and the skirt 49, as well as the collection of the first two zones 30, 30a butt, the relative movement possibilities of the 6a, 6b bars of the frame facing each other in the corner. The remaining degrees of freedom are severely suppressed by union  15 by screws.

The following explains in more detail the angular 16 screwed by means of figure 7. The first fin 25 associated with the head 12 / socket bar 12 is provided with first hole 17, 17a and the second hole 18, 18a threaded, Conical, flanged and made by deep drawing. The second fin 40 associated with the bars 6a, 6b of the frame, to be arranged vertically, it has only one hole, namely third parties holes 17b, 18b threaded, tapered, flanged. In addition, the highlight 26 inset-in mentioned above has been configured in the second fin 40 in shape of a prominence 51 (deep drawing). The lace 26 of highlight-inlet forms a torsion safe for avoid a relative rotation of the bar 8, 10 of the frame and the angle 16 screwed. A layered zone 57 between the two fins 25, 40 It is reinforced with a reinforcing mechanism 58. The latter is basically formed by a groove 59 stiffener (figure 6) Deep drawing. Deep drawing, grooving 59 stiffener forms on its back face, inside the corner of the screwed angle, the shoulder 52 (figure 7), which fits in positive shape connection at recesses 46, 46a of bar 6b a arrange horizontally.

In the exemplary embodiment, they are not provided in the horizontal bars 6b firewall strips. For it, they have 60 wide front faces, to be arranged horizontally, of the door leaf 4 strips 61 comparable firewalls of foaming material in case of fire. The elements 13, 14 Partial horizontal frame bars 6b have been constructed above and below identically in each case. Using the alternative angle 14, the horizontal frame bars 6b, is that is, the header bar 12a and the socket bar 12b, are thus identical together so that the representation of figures 2 and 6 is also representative for the two upper corners of the framework.

For mounting there are several variants. In a first variant, the complete frame 5 can be pre-assembled at the factory and supply it with pre-assembled door leaf 4. In place of assembly, you can then decide if the job is to take place with right or left butt with or without alternative angle. Yes there must be no step down, angle 14 is suppressed alternative in frame bar 6b - socket bar 12b - a place horizontally down according to the type of stop chosen. This it can occur by releasing only two screws, namely the first screws 20, which, after the deletion of the alternative angle 14, they can be screwed again in the angular 13 of the frame and in the 16 angular screwed. If there is absolutely no provision Door threshold, the complete socket bar 12b is suppressed, which again it can take place by releasing only two screws 20b, to namely, the third screws 20c, which join the angle 16 screwed with hinge bar 10 and bar 8 of lock.

In the second variant, they are supplied separately the horizontal bars 6b, 12a, 12b preassembled with the angular 16 screwed pre-assembled and joined by screws in work, only one screw must be screwed again (third screw 20b) per frame corner. The tightening torque of the self-locking countersunk screws 20, 20a, 20c must be fixed in the assembly or in the factory pre-assembly in about 4.5 Nm \ pm twenty%. This pair includes the self-tapping pair of approximately 2 to 3 Nm
