And the aforementioned DE 196 15 902 A1 relates to a fire-resistant wooden frame glass door with the features of the preamble of the appended claim 1, wherein a the largest possible amount of glass should be visible. This known construction is at best sufficient for a fire protection class after T30.

The invention is based on the object, a wooden frame glass door in the preamble Of the type mentioned in claim 1 such that they as T90 fire door a one-sided firing for at least 90 minutes and despite easier Manufacturing has a high quality appearance.

To achieve this object, the invention provides a door with the features of the claim 1 proposed.

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

The invention thus provides a T90 wooden frame glass door with a substantially - almost exclusively and preferably without metal inserts - formed from wood material Frame and at least one door leaf, which consists essentially of a whole or predominantly made of wood material - preferably without metal inserts - formed door leaf frame and an F90 fire protection disk held therein. The thickness of the wooden material - preferably solid wood, more preferably hardwood - formed Zargen- and door leaf frame is more than 90 mm, namely about 100 mm or more. The Door is folded at least twice on both sides parallel to the door pivot axis executed. In each fold section of Mehrfachfalzes is at least one Fire-resistant strips of foamy material in case of fire, around each fold section to seal in case of fire. These amazingly simple measures also succeed a simply constructed as a solid wood frame glass door and thus easy to produce door as a T90 fire door. Surprisingly, such a structure is simpler Solid wood door leaf frame capable of handling the extra heavy F90 glass panes even during burning of the wood material when exposed to fire over safe and tight for more than 90 minutes. Wood materials also have the Fire case extraordinarily positive property of poor heat conduction, so that - in contrast to metal frame doors - to special cooling or insulation measures for Prevention of heat transfer can be dispensed with. In case of fire, the remain already burnt on outer wood layers on the wood material and act as a heat shield.

By a measured perpendicular to the door width side thickness D of the frame and / or the door leaf frame of at least 100 mm, preferably of about 110 mm, it is thus possible on the one hand, despite a very slender appearance of the wooden frame from the door broadside or visible side (top view of the closed door) seen from - one sees only a little Wood and plenty of disc material - to achieve the stability required for a T90 door and on the other hand simply solid wood beams as technically very simple producible and yet without surface coating optically high-quality acting To use wooden material beams for the frame and the glass frame of the door leaf. The Mehrfachfalz prevents tilting even with smaller Türblattschwenkradien of door leaf and frame. The multiple fold is sealed according to the invention thereby, that each fold of Mehrfachfalzes or each other by the folding remote from each other Front side sections of the door leaf or the frame with their own fire protection liners with intumescent material for sealing in case of fire is provided. With "front sides" (also peripheral sides) here are substantially perpendicular to the door broadsides, i. to the sides visible in the closed state of the door, extending narrow sides of the door leaf or in the closed state of the door refers to these door leaf narrow sides parallel Leibungsseiten the frame.

Preferably, the proportion of wood materials of the frame and the frame opposite the disc material in each parallel to the door wide side at the height of the F90-fire protection pane guided cutting plane less than 40%, preferably less than 30%. In other words, the area ratio of the wood materials at the fire attack surface is according to one embodiment, at most 40%, preferably at most 30%, with the remainder of the fire attack surface from the F90 fire screen is formed. Thus, a fire attack attacks mainly on the less sensitive Disc material. In addition to fire protection advantages can be but also achieve a very attractive visual appearance with these measures, which does not give the viewer the impression that he has it here with a special one to do safe fire completion.

According to an advantageous embodiment of the invention is a T90 wooden frame glass door proposed with a frame formed essentially of wood material and at least a door leaf which consists essentially of a wholly or predominantly of wood-based material, in particular metallverstärkungslos, formed door leaf frame and a therein held F90-fire protection glass is formed, wherein the door leaf frame of frame spars is formed, of which at least the vertically arranged frame beams and a frame rail to be arranged horizontally above a measured on the door leaf broadside Overall width and a transverse to the door leaf broadside measured against this total width have greater total thickness, the total width preferably less than about 70% of the total thickness.

For sealing the door gap in case of fire for more than 90 minutes and a targeted Steering or influencing the sealing processes during the fire is the use of different intumescent layers with different properties prefers. Preferably, a first intumescent foams and foams faster second intumescent slower, but with larger volume or larger Inflation pressure. Accordingly, in a particularly preferred embodiment of the invention a first fire blanket in the front sides of the door leaf and a second fire blanket provided in the front sides of the frame, wherein the first and second Fire-protection liners with different types of fire-resistant fire-protection materials - Intumescent - are formed, of which a first faster and / or foams at lower heat and a second with a larger volume and / or foams with a higher foaming pressure or inflation pressure. Next is to discharge In case of fire, the door hinges, which may be anchored in the wood-based materials, cause the due to the fire screen must hold particularly heavy door leaf, preferably, that on the door leaf underside at least one fire protection with a glue layer is provided, with a stronger Aufschäumdruck or inflation pressure foams up as an intumescent used in the upper horizontal and vertical door gaps. In case of fire this foams at least one provided in the lower door gap Fire-proof liners - preferably a variety of such fire-resistant liners provided in the door leaf underside - particularly strong on, so supports the door leaf and relieves the door hinges.

The frame and / or the door leaf frame can be entirely or predominantly made of solid wood, especially from oak, koto or Shorea spp., subg. Rubroshorea (trade name Dark Red Meranti).

a front view of a second, two-leaf embodiment of a T90 glass frame door with wooden frame.

The wooden frame glass doors 1 and 50 shown in the figures each have one beside or two door leaves 2, 2a, 2b, 51 a wooden frame 3. The door leaves 2, 2a, 2b, 51 are basically mainly in a stable a door leaf frame performing glass frame 4 from slow burning wood materials, preferably solid oak, Koto Solid or Dark Red Meranti solid, held F90 fire protection panels 5 formed. The frames 3 are made of the same material as the glass frame 4 of the door leaves 2, 2a, 2b and 51.

The illustrated in Fig. 1 as a first embodiment in front view two-leaf door 1, the frame 3 and two door leaves 2, namely a wing 2a and a passive leaf 2b on. The door leaves 2 are each three-sided, namely at the top horizontal and the two vertical front or peripheral sides, executed repeatedly folded.

The frame 3 is made of three anchored in the masonry framework Zargenholmen, a left vertical Zargenholm 30, a right vertical Zargenholm 31 and an upper horizontal frame member 32, formed. On the left vertical Zargenholm 30 is at the Representation in Fig. 1 of the wings 2a and the right vertical Zargenholm 31 of Inactive leaf 2b, each pivotally supported on four Türbändem 33. The total width ZAMB - Zargenaußenmaß - the frame 3 is here about 2550 mm, for example 2556 mm; The total height ZAMH - Zargenaußenmaß - here is about 2400 mm, for example 2403 mm. The front door broadside - front side or hinge side V - visible frame width ZHB of all frame beams 30, 31, 32 is less than approx. 50 mm, here 45 mm. The Zargenholme 30, 31, 32 are mainly from the slow burning Solid wood made.

The glass frame 4 of the wing 2a is composed of two vertical frame beams 20 and 21, two horizontal frame rails 22 and 23 and an additional, here centered horizontally arranged rung 24 formed. All these parts 20-24 are predominantly from the formed slowly burning solid wood. The visible on the front door broadside V Frame width THB is less for vertical frame beams 20 and 21 as about 100 mm, for example about 70 mm. Also on the front door broadside V visible frame height THH is 22 and 23 for the horizontal frame spars also less than about 100 mm, for example about 70 mm. The visible height HS of Rung 24 is less than about 50 mm, for example 40 mm. In the so formed Glass frame 4 of the wing are used two F90 fire protection panels 5, here both more than about 1050 mm in height, for example 1083.5 mm, and more than about 1100 mm Width, for example, 1145 mm. The F90 fire protection panels 5 are each held by glazing beads 6, here also from the slowly burning solid wood are formed, although other materials for the glazing beads 6 are conceivable. The visible width TFMG of the leaf 2a (Türfalzmaß) is slightly more than that Half of the frame rebate width ZFMB, which is made up of the total frame width ZAMB minus the visible widths ZHB of the two vertical Zargenholme 30 and 31 results. Of the remaining area of the Zargenfalzbreite ZFMB is through the visible width TFMS of the passive leaf 2b filled. Example values are TFMG = approx. 1272 mm, TFMS = approx. 1180 mm, ZFMB = approx. 2466 mm.

The glass frame 4 of the passive leaf 2b is made of two vertical frame beams 25 and 26th and two horizontal frame beams 27 and 28 formed. The frame beams 25-28 exist mainly from the slowly burning solid wood. The upper horizontal Frame rail 27 of the passive leaf 2b has a horizontal frame members 22 and 23rd the visible wing height 2a THH; the band side has the same vertical Frame rail 26 of the passive leaf 2b a vertical frame beams 20 and 21st the visible wing corresponding to visible width THB. The visible width TLB of the The aerofoil 2a facing vertical frame spar 25 is less than the visible width THB of the remaining vertical frame spars 20, 21, 26, for example less than about 50 mm, in particular about 44 mm. For the lower horizontal frame member 28 of the Inactive leaf 2b higher than the other horizontal frame members 22, 23, 27 and with a visible height TUH of less than about 250 mm, in particular of about 200 mm executed. In the thus constructed glass frame 4 of the passive leaf 2b is a single F90 fire screen 5 with more than about 1950 mm in height, for example, 2077 mm in height and more than about 950 mm wide, for example, 1053 mm width used.

The area fraction of the wood materials of the frame 3 and the glass frame 4 on the visible door broad side V, if one disregards the glazing beads 6, amount to less than 40%, as can easily be calculated from the abovementioned values: While the total area G of the in 1 door view surface on the door level (fire attack surface) G = ZAMB × CAGA ≈ 2550 mm × 2400 mm = 6120000 mm 2 is, the amount attributable to the F90 fire disks 5 G s ≥ 2 × 1050 mm × 1100 mm + 1950 mm × 950 mm = 4162500 mm 2 ,

The proportion of the fire attack surface attributable to the disk surface is thus: G s G ≥ 4162500 mm 2 6120000 mm 2 ≈ 68%; ie the wood materials account for less than about 32% of the fire attack area. With the stated more precise example values for the individual heights and widths, an area proportion of the wood materials of less than 30%, namely about 27% for the two-leaf door 1 without consideration of the glazing bead 6 results.

In the following, with reference to the sectional views in Figs. 2 to 6 on the inner Structure of the door 1 received.

Fig. 2 shows a vertical section through the passive leaf 2b. The upper frame spar 32 and the upper frame member 27 are folded double corresponding to each other. At each staggered by the double fold 12 staggered parallel to each other extending end face areas 13, 13a and 13b includes the upper frame member 27 in a correspondingly shaped groove thus a flush with the end face area final first fire protection 8, the below in reference to the representation in Fig. 3 will be explained in more detail. The upper Zargenholm 32 has rabbet seals 14 to the to the door wide sides V (front side or hinge side) and R (back side or opposite side of the belt) parallel walls of Doppelfalzung 12. Next one has the wider one band-side first end face region 13 of the horizontal frame spar 27 opposite band-side first end portion 15 of the frame spar 32 in a corresponding formed groove flush with this first end face area second fire protection 10, on the below in the representation in Fig. 6 will be discussed in more detail. The remaining end regions 15a and 15b of Zargenholmes 32, the staggered due to the double fold 12 staggered parallel to the first end portion 15 extend, however, contain in the present embodiment no fire protection glue. Facing on all of the F90 fire screen Walls 16 of the glass frame 4 includes a first fire protection strip 7 from in Fire case for holding and sealing the glass pane 5 in the wooden frame 4 foaming Material. At the bottom U of the horizontal frame spar 28 and thus at the bottom of the door leaf 2 are several parallel to each other parallel to the door broadside V or R arranged extending second fire protection strip 9 arranged. In the shown Embodiments are four second fire protection strips 9 next to each other at a distance provided to each other and the door broads R and V extending grooves.

In Fig. 4 is a vertical section through the aerofoil 2a is shown. This show corresponding Reference numbers respectively corresponding parts and on the above Explanation is hereby referred to. As can be seen in comparison of FIGS. 3 and 4 of the lower frame member 23 of the wing 2a comparable to the lower level THH executed the lower frame member 27 of the passive leaf 2b. Also correspond to the Profiles of the upper frame members 22 and 27. The glass frame 4 has at all to the Glass pane 5 directed toward walls 16 each have a first fire protection strip. 7 on; accordingly, the rung 24 is provided at the top and bottom thereof.

In Fig. 5 is a horizontal section through the door 1 is shown. As can be seen from a comparison with FIG. 2 or 4, the lateral frame members 30 and 31 correspond in profile to the upper one Zargenholm 32, and the lateral band-side frame spars 20 and 26 the two Door leaves 2a and 2b correspond in profile to the upper frame members 22 and 27. Die the respective other door leaf 2b and 2a facing vertical frame members 21 and 25 are also provided with a double seam 17. These are the door wide sides V and R lying front side portions 18 and 18b respectively thinner than the central end face area 18a executed; and there are each first fire protection 8 opposite. Next is in the other of the other door leaf 2b, 2a facing vertical Frame spars 21, 25 each have a cable channel 11 is provided. With through the cable channel 11 guided electrical connections 21, 25 can be z. B. electric door openers, Connect smart card systems or similar lock control systems. Otherwise For more details of the construction is expressly on the exact drawing Referenced illustration.

As can be seen from Figs. 3, 4 and 5, the frame 3 and the glass frame 4 have a uniform thickness D, which is made thicker than usual in known doors. The thickness D is preferably more than about 100 mm, and more preferably 110 mm. The ratio of each exposed in the event of fire, the fire wood surface to the timber thickness is less than 15,000 mm at the two-leaf door 1 (the timber engaging surface H _1, ie the respectively identical to hinge side V and the hinge side R sum of Zargenangriffsfläche and the door frame engaging surface is about H ₁ = 1.6 × 10 ⁶ mm ² , the thickness D = 110 mm, this gives H ₁ : D≈14.5 × 10 ³ mm). The thickness D is greater than the visible widths THB and THH of the frame spars 20 to 23 and 25 to 26 and greater than the visible width ZHB of the frame spars 30 to 32.

The door 1 has a maximum weight of 250 kg per wing, d. H. a total of 500 kg. you can assume that the door 1 weighs 85 kg / sqm. One has also with choice of Wood materials little influence. The emphasis is on the fire panels 5 certainly.

Because of the large thickness D, the door 1 is executed at least double folded, as the Door leaves 2 otherwise - with single fold or blunt execution - with normal door widths when opening and closing due to too small pivoting radii in the frame 3 tilt. The double folding 12, 17 is difficult to seal in case of fire. One has Therefore, so far have to avoid multiple folds in T90 wooden door area with the effect of not being able to make doors that thick and complicated, difficult to handle or expensive measures for stiffening the door leaves and had to resort to the stamina of the wood materials used. At the here described Door 1 but the double seam 12, 17 is also sealed for T90 requirements, so that the door 1 for forming the heavy glass panes 5 also in the Fire case sufficiently rigid glass frame 4 simply made of solid wood just thicker could be executed. The seal succeeds in the anticipation of several fire protection liners 8 and / or 10 per double-fold and / or by fire-resistant strips 7 and 9 with different dimensions and different response in case of fire.

In Fig. 3 of the lateral and upper frame beams 20, 21, 22, 25, 26 and 27 facing away from the comprehensive glass pane 5 facing end face multiple parallel and at a distance next to each other endseitig as continuously as possible continuously circulating used first fire protection 8 is shown in profile , It is formed from a layer of a first intumescent layer 81 embedded between a lower layer 80 of high-density fiber material (HDF) and a cover fumier 82 of the same material as the slow-burning solid wood. Exemplary values for the width B of the first fire protection insert 8 and the thicknesses D ₁ , D ₂ , D _{3 of} its three layers 80 - 81 are: B = about 15 mm (± 5 mm), D ₁ = about 2.5 mm (± 0.5 mm), D ₂ = about 2 mm (± 0.5 mm) and D ₃ = about 1.5 mm (± 0.5 mm).

In Fig. 6 of the lateral and upper Zargenholmen 30, 31 and 32 at the wider band-side end face regions 15 as continuously as possible circumferentially inserted second fire protection strips 10 is shown in profile. It is formed of a second intumescent layer 101 layer sandwiched between a lower layer 100 of high density fiber material (HDF) and a top veneer 102 of the same material as the slow burning solid wood. Exemplary values for the width B _{10 of} the second fire-protection inserter 10 and the thicknesses D ₄ , D ₅ , D _{6 of} its layers 100, 101, 102 are: B ₁₀ = approx. 46 mm (± 5 mm), D ₄ = approx. 2.5 mm (± 0.5 mm), D ₅ = approx. 2 mm (± 0.5 mm) and D ₆ = approx. 1.5 mm (± 0.5 mm).

The first intumescent agent 81 is a very fast responding, i. at relatively low Heat already used intumescent material. This is suitable for example, one sold by BASF AG under the trade name PALUSOL Material; a glass fiber and water-containing, foaming on exposure to sodium silicate. The second intumescent agent 101 also foams up under the effect of heat, But speaks slower than the first intimidating agent 81, but with a larger one Blowing volume, so that even larger gaps are sealed. This is suitable a material sold by PROMATECT under the trade name "Promaseal" slower than palusol, but more effective foaming material.

For forming the second fire protection strip 9 accommodated in the door leaf underside U. an intumescent is provided, which with very high foaming pressure or inflation pressure foams. Specifically, several parallel stripes of a third intumescent, that of the company Rolf Kuhn GmbH in Tutzing-Garatshausen under the trade name ROKU-Strip is distributed, housed, a material that under heat creates a very strong expansion pressure

In the event of a fire, the first, fast layering agent 81 (palusol) - the one in the embodiments shown in the first fire protection 8 in the door panel 2 is housed - quickly, swells and seals even at low heat the door crack against fire and smoke. Then, with prolonged exposure to fire swells the second, slower but more swelling intumescent 101 (Promaseal) - here in the second fire protection glue 10 - filling up any gap and the respective door leaf 2 festquillt in the frame 3. Meanwhile, the first worry Fire protection strip 7 in the event of fire foaming material between the glass 5 and the glass frame 4 for setting and sealing the glass frame edge, when the glazing bead 6 fails in the fire (e.g., burns off). The second fire protection strips 9 on the underside U press against the door leaf 2 and hold its weight, to relieve the door hinges in case of fire, or to compensate for their failure.

Oak burns off relatively slowly. But especially important is the sealing of the joints and the stability of the door, i. Also, the glass frame 4. Therefore, the thickness of the wood-glass frame 4 and the relatively slow burning wood.

FIG. 7 shows yet another embodiment of a T90 wooden frame glass door. it is a single-leaf door 50 with only one wing 51 as the only door leaf 2 acts. The door 50 is executed repeatedly folded at least on three end faces. In each case with respect to the door 1 corresponding parts are designated by the same reference numerals, and reference is made to the above explanations for explanation thereof. The inner one Structure of the door 50 shown here results essentially (the known arrangement of castles and tapes once disregarded) from the profiles of near the wall extending spars 30, 31, 32, 20, 22 and 26 in Figs. 4 and 5 and at according to the continuous design of the glass pane 5. However, is also in the lock-side frame spar 21 'of the door leaf 51, although the profile of the frame spar 26 similar, the cable channel 11 is provided. The total width ZAMB 'of the door 50 is about 1370 mm, the height of the glass sheet 5 of the door panel 51 is more than about 2150 mm, for example about 2207 mm; the width of this glass sheet 5 is more than about 1100 mm, for example about 1132 mm; otherwise the wooden parts correspond in theirs Profile dimensions of the explained in the first embodiment values. Also at the door So 50 are the frame members 20, 21 ', 22 and 23 of the glass frame 4 more thick than wide.

The ratio of the wood attack surface to the wood thickness is less than 8,000 mm for the single-leaf door 50 (the wood-engaging surface H ₁ is approximately 7.8 × 10 ⁵ mm ² , the thickness D = 110 mm, this gives H ₁ : D≈7.1 × 10 ³ mm), the proportion of the wood attack surface on the total attack surface (ignoring the glazing beads 6) in the case of the door 50 is less than 30%, with the exemplary exact values being approximately 24%.

When dimensioning the T90 wooden frame glass door 50 is considered upper limit in the ratio Wood material to glass at the fire attack surface of, for example, about 30% wood attack surface towards 70% glass output. You may be able to change the ratio also set a little higher (for example, 40% wood material to 60% glass). these are then already relatively broad Frisians.

The double seam 12 is present at each of the doors 1, 50, but has fire protection rather disadvantages, as it is harder to seal. But if you do not have a double fold 12, the door would not open. The door 1, 50 is so thick that with narrow doors the pivot radius would lead to tilting of the door leaf 2 and 3 frame. you would therefore have to make the doors very wide, if one blunted rebated door leaves 2, 2a, 2b, 51 would like to provide. Due to the specially sealed double seam 12, 17 can be solve this problem.

The arrangement of several thinner first fire protection grips 8 and second Fire protection strip 9 has among other things, a reason that the fire protection Intended therein intumescent are mounted circumferentially on three sides have to. In the castle area the first fire protection ledger 8 would be interrupted, resulting in Irregularities in sealing could result. Therefore, so many first fire protection liners 8 placed side by side. In addition, you should always only from the visible side look on wood.

The difference between the preferred materials as intumescent materials Palusol, Promaseal and ROKU-Strip is the following: Palusol is the fastest and seal first; Promaseal is slower, but can do more Fill cavity and also pushes stronger; Rokustrip has the most power. One can Actually here already speak of violence, the door leaves 2 are in case of fire of the ROKU strip strip held. As a result, the door leaves 2 are pushed up and the bands are relieved.

There are in the glass frame 4 on the side facing the glass pane 5 16 still the thin first fire protection strip 7. Through this fire strip 7 is the Glass pane 5 when burning in the door 1, 50 held. The glazing beads 6 burn after a certain time, so that the glass pane 5 alone by pressure in the door 1, 50th is held.

One aspect to increase the service life is also the special arrangement and the Dimensions of the fire protection strips and strips 8, 9 and 10. The in the door frame or the Frame 3 used second fire protection strip 10 with the second Dämmschichtbildner 101 is relatively wide (more than 40 mm, here 46 mm). Opposite him are also intermediate groove areas the front side portions 15 of the door frame spars, where there is no first fire protection liners 8 and therefore also in case of fire an initially constant Provide counter pressure surface.

Die.Türblätter 2, 2a, 2b, 51 are therefore basically nothing more than massive wooden frame around the F90-Feuerschutzscheibe 5. By the thickness of approx. 110 mm succeeded, one To achieve very low view width of the wood-glass frame 4 with appropriate stability (less wood attack surface in case of fire, also optical advantages). The glass panes 5 can optionally be divided by additional rungs 24.

A particularly attractive appearance of the doors 1, 50 shown here is achieved by that the sum of each visible on the door leaf broadsides V and R wooden frame stringer surfaces is the same, i. that in the door closing state the sum of the on the band side V visible Zhargenholmbreite ZHB and visible on the hinge side V door leaf frame width or height THB or THH is substantially equal to the sum of the Gegenbandseite R visible Zargenholmbreite and on the Gegenbandseite R visible door leaf frame width or height is. In particular, this sum is also equal to the visible in the door closing state total width of the facing each other Door leaf frame spars 21 and 25 formed in the door 1 middle wooden frame Holmes. In this way, the doors shown here optically perfect in one (not shown) fixed fire-resistant wood glazing with appropriate width integrate their wooden frame spars.
