Description

The invention relates to a fire door with a door leaf frame construction and a glazing inserted therein. Moreover, the invention relates to a system and a Process for the preparation of such fire protection door leaves and one with such Fire protection door leaf provided fire door.

Fire doors are part of the fire protection, their provision many times are prescribed by building regulations, especially in public buildings. Fire protection closures are in Germany and in Europe, among others, by the DIN 4102 and EN 1634 standardized. They require a building authority approval. To one To obtain such approval are fire door designs in a fire test tested. Depending on whether the doors are at least 15, 30, 60 or 90 minutes one withstand one-sided exposure to fire under DIN conditions (DIN 4102 Part 5), they are referred to as T15, T30, T60 or T90 fire doors. A particular Type of fire doors in the form of sheet steel doors are standardized by the DIN 18082. For steel sheet doors, which are manufactured according to this standard, you do not need one carry out a separate fire test. These DIN sheet steel doors are distinguished by a particularly cost-effective manufacturing process. The door leaves of these fire doors according to DIN 18082 are made of a box plate and a cover plate formed, which enclose a cavity filled with insulating material.

There are also fireproof glazings and glazed fire doors on the market. The door leaves of such glazed fire doors have a door leaf frame and a fire protection disk held therein as a door leaf filling. Such glazed Fire doors require a separate approval. The known glazed Fire doors are usually very elaborate and optically high quality trained and accordingly expensive.

While the aforementioned relatively inexpensive DIN sheet steel doors usually in function rooms, such as basement rooms or production areas of commercial enterprises, are used, glazed fire doors usually find in higher quality objects such as As office or hotel buildings use.

In particular, the fire door leaves according to DIN 18082 are depending on other Requirements in various thicknesses produced in industrial mass production.

The object of the invention is to provide a glazed fire protection door leaf, which with relative can be industrially manufactured in less than a few parts to be stockpiled and yet has a visually appealing appearance.

This task is accompanied by a fire door with the features of the Claim 1 solved.

According to the invention, in a fire protection door leaf with a door leaf frame construction and a glazing inserted therein the glazing at least one fire screen and another disc up. These two discs are by means of a Spacer device spaced so that it is approximately flush with the broad side surfaces complete the door leaf frame construction or that of each other opposite broad sides of the two discs at least in the vicinity of the broad side surfaces the door leaf frame structures are arranged. This can be different thick door leaf frame constructions, each with a same pair of glass panes glazed at the same, visually appealing broadside view. you each must provide only a suitable spacer device. The glass panes Close even with different door leaf thicknesses with about the door leaf frame construction so that, despite the proposed glazing a uniform door leaf body completely without gradations on the door leaf wide surfaces or at least without visually particularly striking gradations arise on these broad surfaces. A measure of about 5 mm for a stage is still as visually hardly noticeable and thus still essentially be flush. But it also comes down to the relative other dimensions; small, thin door leaves become smaller Gradations attract more attention than large thick door leaves with structured surfaces. More generally, the invention is directed to a substantially uniform optical Impression of the broadside surfaces also of different thick glazed fire doors from.

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

The invention is particularly for the glazing produced by the DIN 18082 Fire-resistant sheet steel doors with box sheet and cover sheet suitable. By application the invention for glazing such door leaves made according to DIN is a Particularly cost-effective fire protection door leaf with visually appealing glazing created. Accordingly, the door leaf frame construction is preferably formed by a sheet metal fire protection door leaf construction. This further preferably has one Chest sheet and a lid sheet and a filling in between. The box sheet and the cover plate then form the respective broad sides of the door leaf frame construction. To produce this door leaf can be z. B. corresponding fire doors in accordance with DIN 18082 and then to form a glazing cutout Cut centrally and the thus cut door leaf body by means of the spacer stiffen and then insert the two discs. alternative you could equal a suitably cut box plate and cover plate possibly with insertion of the spacer device to the door leaf frame construction connect.

When glazing is preferably only a fire screen is used, so that the Overall construction is inexpensive. Such fire screens are on the Market as F15 discs, F-30 discs or with correspondingly higher fire protection requirements available. They consist of several layers of transparent Material, in particular glass, with usually transparent fire-resistant cooling materials between. As in the glazing invention yet another disc is used, the fire door panel according to the invention also in one embodiment with a fire screen with lower fire classification also overall meet a higher fire classification. For example, you can use it make a T30 door leaf on an F15 disc.

Accordingly, this additional disc does not fulfill a fire protection function. It is preferable to do this only as a so-called G-glass. Preferred materials for this are simple float glass, or more preferably safety glass, such as toughened safety glass (ESG), laminated safety glass (LSG) and so on Depending on requirements also used insulating glass or toughened glass or other tempered glass become. Even ornamental glasses that give the door a correspondingly higher-quality appearance or lessening the transparency and yet letting light through, can be used become. By the invention it is thus possible without major fire protection Effort very different optical impressions of the glazing and quite different To fulfill functions of the glazing, simply by an appropriate Function glass is used for the further disc.

The spacer device preferably has an interposed between the discs Spacer bar made of a fire protection material. Preferably, the spacer device serves - Especially when using a sheet metal frame construction for stiffening the door leaf frame construction through the window opening mechanically weaker compared to the original DIN door leaves is. Accordingly, the use of appropriate stiffening elements in or at the spacer means between the sheets forming the broad sides preferred. Now if the spacer strip from a fire-resistant cooling fire protection material such partial reinforcements may have no adverse effects on the Fire protection function of the door leaf can be used. The running through in the thickness direction Metal bridges formed thermal bridges could otherwise in case of fire the conduct hot temperature through the thickness of the door leaf. The fire protection material of the cover strip For example, it releases moisture, which evaporates in case of fire for cooling contributes to the metal bridges. Or it generally has a material that in case of fire his State of aggregation changes, whereby the energy required for the state change of the penetrating fire heat is withdrawn. This leaves the fire protection facing away Side cooler. Thus, the fire protection conditions, according to the appropriate Standards also provide for certain temperature limits on the non-brand side, be fulfilled.

Since you through the two discs arranged between the discs Part of the spacer device, this is preferably consistently as spacer strip (and not interrupted, for example, in the form of spacer blocks) formed. At least the visible surface of the spacer bar is more preferably optical hardened and tempered. For this purpose, it is clad, for example, with a panel or veneered. Or it is coated or painted with a visually appealing material.

• Enclose and hold the glass panes in the manner of a glass strip.

To hold the discs in place, the spacer means is more preferred Execution of the discs on the outside comprehensive profile strip device. The Profile strip device further preferably has a profile strip for stiffening the Door leaf frame construction on. To fulfill the glazing beads function has the profile strip device preferably two legs for encompassing the outer surface of the two Washers, which by means of a spacer between them - preferably the Spacing strip mentioned above - are spaced. The distance between the Legs also preferably corresponds substantially to the thickness of the door leaf frame construction. To determine the leg distance has the profile strip device preferably a bridge between the legs. The bridge is preferably as part of a Profile formed a profile strip. The profile strip is preferably formed of metal and further preferably formed from steel sheet, which, for. In a profiling machine, has been correspondingly cold worked. To the in case of fire led by the footbridge To minimize heat, the bridge may be pierced with through holes. The Through openings are preferably transverse to the thickness direction of the door leaf extending elongated slots formed what the contributing to the temperature line Cross-sectional area lowered without affecting the rigidity over charge. To further minimize the heat provided by the bridge in case of fire, this is more preferably at least one side with a fire-resistant fire protection material Mistake. This may, for example, the fire protection material of the spacer be. There are also fire doors, which in case of fire at their faces Moisture and thus also when it rests on the bridge to its cooling contribute. The bridge can also on its entire extent in the thickness direction one-sided or be provided on both sides with fire protection material. Alternatively, however currently less preferred because more expensive and expensive in design and manufacture, the web is formed of a poorly heat-conducting material.

To facilitate the insertion or replacement of the discs is the profiled strip device preferably constructed of a plurality of interconnectable parts, wherein a first part has a first of the legs and a second part has the second leg. The parts are preferably releasably connected to each other, for example with each other screwed.

In Fig. 1 is a fire door 3 for a in Figs. 2a-2c shown, made of sheet steel manufactured fire door 1 shown in side view on one of the broadsides. The Fire door 1 has a steel frame 2 and a fire door 3. The door leaf 3 is hinged to door hinges 4 hinged to the frame 2. The door leaf 3 has a door leaf frame construction 5 with a window opening 6, in which a glazing 7 is used.

The door leaf 3 may be formed differently thick. In Fig. 2 are exemplified three different Embodiments of the door leaf 3, each with different thicknesses a, b, c in Section along the line II - II of Fig. 1 shown.

The door leaf frame construction 5 is made by cutting out the window cutout 6 made of sheet steel door leaf, analogous to the corresponding DIN 18082 a box plate 8 and a cover plate 9 is made. The thus formed Cavity 10 is filled with an insulating material 11.

2a shows a first door leaf 3a with a small first thickness a, for example approx. 45 mm. The door leaf 3a is here in so-called Dünnfalzausbildung with a thin Fold 12 provided. In fold 12 are an edge region of the box plate 8 and one around it around bent edge region of the cover plate 9 directly to each other. Below shows Fig. 2b a door leaf 3b with a slightly larger second thickness b, for example, about 55th mm. In the illustrated example, the door leaf 3b has a slightly thicker fold 12b.

Below this, FIG. 2c shows a third door leaf 3c with a third, even greater thickness c, for example, of about 65 mm. The fold of this third door leaf 3c is in the example as formed so-called thick fold 14, where by corresponding bends of Edge regions of box plate 8 and cover plate 9, a rebate cavity 13 is formed.

Corresponding, not shown here leaves without glazing are often in the manner shown with the different thicknesses a, b, c produced.

Fig. 3 shows how these different thickness door panels 3a, 3b, 3c in simpler cost Way can be provided with a visually appealing glazing 7. 3 shows the section along the line III-III of FIG. 1 through one of the three Door leaves 3a, 3b or 3c. The thus generally designated 3 door leaf has the door leaf frame construction 5 and the glazing 7 on. The glazing 7 has a fire screen 15 and another disc 16 on. The fire protection pane 15 is here a F15 disc. The further disc 16 is here a G-glass disc. The two Discs 15, 16 are passed through a glass retainer or spacer 17 held on the door leaf frame structure 5 at a distance from each other.

The spacer 17 has a spacer in the form of a spacer side 18 and a profile bar means 19. The spacer bar 18 holds the two Disks 15, 16 with such a distance from each other that their respective outward directed broadsides 20, 21 almost, but not in the example shown here completely, flush with the outer broad side surfaces 22, 23 of the box plate 8 and cover plate 9 are arranged.

For each of the possible thicknesses a, b, c, there is a correspondingly formed spacer device 17 (not explicitly shown), the two discs 15, 16 in the zu the thickness a, b, c holds appropriate distance.

The profile strip device 19 serves to stiffen the door leaf frame structure 5 at the window cutout 6. Although only the vertical sides of the window cutout 6 in section III - III, it should be clear that all four edges of the Window section 6 can be formed as shown, as is the Exploded view of Fig. 5 can be removed. The transitional area of the glazing 7 and the door leaf frame construction 5 is covered on both sides by cover strips 24.

The construction of the spacer device 17 will be described below with reference to the illustration in FIG Fig. 3 explained in more detail. The spacer 17 consists essentially of the Distance retaining strip 18 and the profile strip device 19. The profile strip device 19 is formed by a Z-profile strip 25 and a substantially flat glass strip 26th

The spacer strip 18 is essentially a fire-resistant fire protection material formed, the at least for stiffening and / or optical remuneration his, the profile strip device 19 side facing away from a sheet is planked. In In the illustrated example, the spacer bar 18 is a GKF beam 27 having a Sheet metal coating 28 on its visible side 29 and the two here to capture the Glass panes 15, 16 serving narrow sides 30, 31. At its fourth, one the Distance in the thickness direction determining web 32 of the profile strip device 19th facing side 33, the fire protection material is released. The sheet metal coating 28 may be further optically tempered, for example, painted or powder coated be.

The profile strip device 19 is essentially formed from sheet steel. She rejects the Web 32, one of the thickness a, b, c of the door leaf 3 corresponding expansion in Thickness direction has. The web 32 corresponds more precisely in the embodiment of the thickness a, b and c of the door leaf 3a, 3b, 3c minus the sheet thicknesses of Box sheet 8 and cover sheet 9 and minus the sheet thickness of the web of the 32nd further projecting profile areas of a hereafter explained in more detail Z-profile strip 25. The profile strip device 19 has a U-shaped partial profile with the web 32nd and two legs 34, 35, which fulfill the function of glass retaining strips and the Outer sides 20, 21 of the two discs 15, 16 border edge.

At the bottom of the profile strip means 19 with a further part profile, the Attachment and / or stiffening is provided, for example, with one or more Edge flags or with strip-shaped flanks.

In order to use the discs 15, 16 with the spacer bar 18 in between, the profile strip device 19 is here, as can be seen in FIGS. 3 and 5, from several parts, namely from that in Figs. 6 to 8 in more detail individually shown Z-profile strip 25 and one in Figs. 9 to 11 in more detail individually formed flat glass strip 26, wherein the Z-profile strip 25 the first Leg 34 and the web 32 and the flat glass bar 26, the second leg 35th forms.

The Z-profile strip 25 shown in Fig. 6 to 8 is at its leg 34th opposite side provided with a flange 36. The transition area between the flange 36 and the web 32 is at regular intervals with Fastened areas provided here in the direction of the course of the web 32nd having recessed receiving holes 38.

The glass retaining strip 26 shown in FIGS. 9 to 11 has on its Z-profile strip facing side at appropriate intervals flag-like projections 37, the attack the attachment areas and also with corresponding hole holes 38 'are provided, which engage flush in the Tutungslöcher 38 and there with Countersunk screws 39 are detachably screwed. As shown in Fig. 10, the Glashaltele 26 simply a flat piece of sheet metal, which screws to the Construction is provided.

As best seen in FIG. 3, the spacer bar 18 is also included connected by means of countersunk screws 40 with the profile strip device 19.

As can be seen from FIG. 8, the web 32 of the Z-profile strip is provided by means of slots 41 breached.

Fig. 5 shows an exploded view of the attachment of the individual parts of the glazing with the glazing frame and also the attachment between Z-profile strip 25 and Glazing bar 26. It is also the corresponding area of the door panel, here the Cover sheet 9 shown. This cover plate 9 is corresponding to the flag-like Projections 37 provided with recesses 42 and projecting in between Areas 43 with the flange 36, for example by screws or through Welding 47 such as spot welding or beam welding or through Riveting connected.

As shown in FIG. 3, which shows the section III -III of Fig. 1 and the Fig. 5 can be removed is the bridge 32 on both sides with fire protection material, such as GKF (plasterboard) surround. A first strip 45 of fire protection material covers the web 32 its entire thickness range between the two legs 34 and 35 and thus also between the end faces of the two discs 15, 16 and the web 32 and between the spacer bar 18 and the web 32 inserted. A second strip 46 of Fire protection material is between the insulation material 11 and the web 32 innensetig appropriate. The strips 45, 46 are together with the spacer strip 18 by means of the screws 40 screwed to the web 32. The screws 39 secure the Glashalteleiste 26 to the Z-profile strip 25 and both strips 25, 26 on the Fire protection material and / or insulation 11.

As fire protection material for the spacer strip 18 and the two strips 45, 46th In particular materials come into consideration, which give off moisture in case of fire, such as z. A Calzitherm®-marketed material or sodium silicate-based materials. For the fire protection panel 15, there are different F15 fire protection panels on the market. For example, the company Promat offers a F15 disc, the a one-sided exposure to fire for 25 minutes. Another of the Fa. Promat offered F15-type fire-resistant glass last 20 minutes. Together with the Distance holding device 17 and formed as a G-glass disc another disc 16 can thus be glazed door leaves 3 for T30 fire doors.

The bordered edge regions of the two disks 16, 15 are each sealed with silicone. In this way, a wet glazing is formed.

The cover strip 24 is preferably glued. It has mainly decor function and could be made of steel or other materials like stainless steel or aluminum or one be made of other light metal alloy. Also non-metals like glass, ceramics or Plastics are possible. In the illustrated example, the cover strip 24 is part of a Cover frame 54, which may be integrally formed and thus easy to handle and can be attached.

Figs. 12 to 14 show a second form of glass retaining strip 50, which at a in the following described in detail second embodiment of the door panel 3 is used. The glass retaining strip 50 differs essentially by the provision of perpendicularly projecting tabs 52, which for further positive connection with the Z-profile strip and thus serve to stiffen the entire construction. Accordingly, the entire second embodiment is different from the first one Embodiment only by an adapted to this additional tab connection Education. Wear corresponding parts as in the first embodiment corresponding reference numerals and the description thereof may be the above illustration to be taken in the first embodiment.

FIGS. 15 to 17 show a second one designed to match the second glass strip 50 Z-profile strip 56. This is provided with receptacles 58, in which the tabs 50 can be inserted. In the example shown, the web is the Z-profile strip 56 provided with bow-shaped notches 59, which is so far from the web 32 in Direction to the glass sheets 15, 16 protrude that the tabs 52 substantially clearance between the web 32 and the bow-shaped notch 59 positive fit can be introduced.

Fig. 18 shows, corresponding to Fig. 3, the section along the line III-III of Fig. 1 for the second embodiment. Fig. 19 shows the section along the line XIX-XIX of Fig. 18 and illustrates the position of the tabs 52 in the second embodiment. Like this Illustrations can be removed, the second strip 46 of fire protection material to the the tabs 52 having points provided with recesses 60.

Fig. 4 shows for comparison the corresponding section in the first embodiment. As can be seen, here lacks the tabs 52 on the vertical glazing edges. however can also, as shown here, at the horizontal glazing edges one or several of the tab connections 52/59 be provided.

As best of the exploded views of Figs. 5 and 20 for the two Embodiments will be apparent when inserting the window 6 in a Sheet metal door leaf construction of one of the door leaf sheets 8, 9 here the cover sheet. 9 rectangular-tooth-shaped incised. Thereby, projecting portions 43 and Recesses 42 formed. In these recesses 42, the projections 37 of the Glass retaining strips 26, 50 added. The glass retaining strips 26, 50 take the place of the door leaf sheet 9 and do not wear. The above areas have preferably approximately centrally in each case at least one of the welds 47 or like fasteners with which the Z-profile bar 25 or 56 directly to the Door leaf sheet 9 is connectable.

In the following, with reference to FIGS. 5 and 20, the production of the Door leaf 3 with different thicknesses a, b, c explained. The procedure is as follows:

First, a solid material door leaf 3a having a certain thickness a is provided. Then the window opening 6 with the teeth 43/42 at the edge region cut out. The second fire-resistant strip 46 is more suitable from a range Thicknesses selected or cut and pasted. From a range with Z-profile strips 25 or 56, which correspond to the thicknesses a, b and c, becomes the thickness a the door leaf 3a matching Z-profile strip 25 or 56 selected and with the Edge regions of box plate 8 and cover plate 9 connected. In the illustrated Example is then according to the first fire protection material strip 45th selected according to its thickness or cut and inserted. Then one will the two disks 15, 16 - in the example, the fire protection disk 15 - to the first Leg 34 applied and selected by means of a corresponding to the door leaf thickness Spacers, d. H. here the corresponding spacer bar 18, by Screwing the spacer strip 18 by means of screws 40 fixed to the web 32.

Then the second disc, here the disc 16, inserted and by screwing the glass strip 26 and 50 fixed. In the second embodiment, the Tabs 52 by appropriate insertion of the glass strip 50 in the thickness direction in the Shots 58 inserted. Subsequently, the cover strips 24, i. this one Cover frame 54 glued.

By appropriate storage of different thickness spacers 17, the various door leaf thicknesses a, b, c with substantially flush Glazing 7 glazed.

As can be seen from Figs. 3 and 18, these constructions are the outside Wide side surfaces 20, 21 almost flush with the broad side surfaces 22, 23rd the door leaf frame construction 5. Specifically, the surfaces 20, 21 of the glazing 7 to the thickness of the flush with the sheets 8, 9 flush legs 34, 35 inwards added. This thickness corresponds to the usual sheet thicknesses and is at most about 5 mm. The displacement of the glass pane 15, 16 inwards is preferably such that they visually not noticeable. Serve also the cover strips 24, which actually in the Laid embodiments offset dislocation of the surfaces 20 and 23 or 21 and 22. The offset between these areas is in each case independent of the respective door leaf thickness a, b, c. The differences between the door leaf thicknesses a, b, c be by different width spacer strips 18 and correspondingly wider Bars 32 balanced. This is only the cavity between the discs 16, 15th at the different thicknesses, a, b, c larger or smaller.

As can be seen from FIGS. 3 and 18, the heavier one is shown in the examples shown Fire protection pane 15 on the side of the structure stiffer Chest sheet 8 arranged. The fire protection disk 15 is also at the with integral with the web 32 and thus held more stable leg 34. The lighter one another slice 16 is easier with the so far somewhat difficult near the edge Handle insertion with subsequent screw connection.
