Definitions
- the invention relates to a fire protection door with a frame and a door leaf pivotably arranged on the frame, in which the frame and door leaf are made of metal, preferably steel, and / or fireproof glass and in which there are several between the frame and the door leaf , at least two, door hinges are arranged.
- Such fire protection doors are known from the prior art. They are subdivided into doors with different resistance to fire, and because of their function, these fire protection doors are made of fire-resistant materials.
- Frame and door leaf are preferably made of steel. However, it is also possible to manufacture the door leaf from a combination of a steel frame and a fire-resistant glass pane inserted into the frame. Between the frame, which is also referred to as the frame, and the door leaf, connecting elements are arranged, by means of which the door leaf is pivotally attached to the frame.
- door hinges These connecting elements are referred to as door hinges, these door hinges generally consisting of a lifting element firmly connected to the frame, which has at its free end an axis of rotation on which a second element of the door hinge is placed, which is firmly connected to the door leaf is.
- the door hinges are also made of metal, namely steel.
- the invention is based on the task of creating a generic fire-protection door which can be produced inexpensively, is light in weight and can be used at least as a T30 fire protection door, in particular the stabilizer ⁇ is increased in the event of fire.
- the solution to this problem provides for a generic fire protection door that the door hinges consist of a material that is different from the frame and door leaf, preferably made of light metal, and that between the frame and the door leaf, at least in partial sections, preferably Arranged along the frame part running vertically in the region of the door hinges is a sealing element which expands in the event of a temperature rise causing a fire.
- a fire protection door designed in this way has the particular advantage that the use of light metal door hinges results in a reduction in weight and, at the same time, a reduction in production costs, since light metal not only has a low specific weight than steel, but also better processability. Since the use of light metal for the production of door hinges in fire protection doors leads to the fire resistance of the fire protection door being reduced due to the light metal melting at low temperatures, it is provided that the door leaf is thereby held in the frame in the event of a fire is that a sealing element is arranged between the door leaf and the door frame, which expands in the event of a temperature rise caused by a fire in such a way that the door leaf is fixed in the frame, so that the fire resistance of such a fire protection door is not affected by the door leaf falling out of the frame ⁇ is pregnant.
- the sealing element preferably extends over the entire vertical length of the frame part in the region of the door hinges. In this way, not only is the door leaf wedged in the frame by the expanding sealing element, but also a sealing of
- the frame has a preferably undercut recess in its surface running in the area of the door hinges and facing the door leaf, into which the sealing element is inserted.
- the door leaf on its surface running in the region of the door hinges and facing the frame has a preferably undercut recess into which the sealing element is inserted.
- a sealing element to be inserted into the recess in the frame and in the recess in the door leaf.
- the undercut recesses have the advantage that a sealing element inserted into these recesses is positively connected to the door leaf or frame, so that the sealing element cannot fall out of the recess, for example due to vibration or vibrations.
- An improvement in the sealing of the fire protection door in the event of a fire is achieved in that a sealing element is arranged both on the edge which runs vertically in the region of the door hinges and in the region of the lock. In this way, in the event of a fire, sealing elements expand on both vertically running surfaces of the door leaf, which hold the door leaf in the frame when the door hinges have already been destroyed or damaged.
- the door leaf on its in the area of the door band vertically extending surface has at least one bolt which engages in a corresponding opening in the frame when the door is closed.
- the bolt preferably has a free conical end and at its second end a screw thread which is screwed into a bore formed in the door leaf with an internal thread.
- the conical end of the bolt enables the arrangement of an essentially cylindrical bore within the frame.
- a closing device is arranged between the frame and the door leaf, which device transfers the door leaf into the closed position after opening.
- the stability of the fire protection door is increased in particular by holding elements being arranged between the frame and the door leaf, at least in the region of the door hinges, which engage in the frame and in the door leaf when the door leaf is closed, the door leaf in Support the fire in the vertical direction and are fixed either on the door leaf or on the frame.
- the holding elements are either attached to the frame or to the door leaf in the region of the door hinges, so that when the door leaf is closed, the door leaf is supported in the vertical direction via these holding elements if, for example, the door hinges are damaged or destroyed in the event of a fire , so that the door hinges can no longer perform the holding function between the frame and the door leaf.
- the door leaf is thus held in the frame on the one hand by the sealing element which expands when the temperature rises and on the other hand by the holding elements, so that the door leaf does not fall out of the frame in the event of a fire.
- the holding elements are either attached only to the door leaf or only to the frame, the holding elements being pushed into the correspondingly opposite component of the fire protection door, namely into corresponding openings, when the door leaf is moved into its closed position.
- three holding elements are arranged between the door leaf and frame, two holding elements being arranged in the area of the door hinges and one holding element between the door hinges.
- This embodiment has the particular advantage that an improved sealing of the door leaf within the frame is achieved via the third holding element, since the third holding element essentially prevents deflections of the door leaf due to the effects of heat.
- the holding elements are designed as safety bolts, preferably made of steel. These bolts have sufficient fire resistance, which is necessary in order to design the fire protection door as a T-30 fire protection door. Steel has proven particularly useful as a material, since steel is sufficiently heat-resistant.
- the holding elements consist of a flat steel, the holding elements preferably being welded to the frame or to the door leaf.
- the design of the holding elements from a flat steel has the particular advantage that a sufficiently large contact surface of the holding elements on the frame or the door leaf is present, so that, for example, welds provide a sufficiently stable connection between the holding elements and the door leaf or the frame ⁇ can be put.
- the holding elements are preferably designed to be cranked twice, the holding elements preferably being fastened in the door leaf and guided in corresponding openings in the frame.
- This embodiment has the advantage that the cranking of the holding elements ensures that the door leaf can be opened and closed easily, that is to say as smoothly as possible, while at the same time the holding function in the event of a fire is reliably provided via the holding elements.
- the holding elements are arranged in the region of the surfaces of the door leaf and / or frame opposite the door hinges. This has the advantage that the holding elements are preferably arranged on the side of the fire protection door facing away from the source of the fire, so that the holding elements are exposed to high temperatures only after a certain exposure time to the temperature caused by the fire.
- the door hinges consist of aluminum.

- the fire protection door 1 shown in FIG. 1 consists of a frame 2 which has two vertically running side walls 3 and a lintel wall 4 connecting the two side walls 3 to one another. On the side walls 3, fastening elements 5 are arranged at regular intervals, by means of which the frame 2 is connected to the masonry (not shown). Furthermore, the fire protection door 1 has a door leaf 6 which is arranged in the frame 2 so as to be pivotable.
- the door leaf 6 consists of a frame 7 and a refractory glass pane 8 held in the frame 7. Between the frame 7 and a side wall 3, two door hinges 9 are arranged at a distance from one another. On its vertically extending side opposite the door hinges 9, the door leaf 6 has a handle 10 and a lock 11. With the handle 10, a closing element 12 (FIG. 3) is confirmed, which engages in a corresponding latch 13 (FIG. 3) when the fire protection door is closed.
- each door hinge 9 consists of an essentially L-shaped lever 14 which is screwed to the side wall 3 with a screw 15. Furthermore, each door hinge 9 has a lever 16 of essentially L-shaped design, which is screwed to the frame 7 of the door leaf 6 with a screw 17. The free ends of the levers 14 and 16 are one above the other arranged and interconnected by means of an axis 18. The door leaf 6 can be pivoted relative to the frame 2 about this axis 18.
- the door leaf 6 is automatically returned to its closed position by a closer 19 arranged in the upper region of the fire protection door 1.
- This closer 19 is fastened on the one hand to the lintel wall 4 of the frame 2 and on the other hand to the frame 7 of the door leaf 6.
- fire insulation panels 20 are arranged in the frames 2 and 7 of the fire protection door 1, which contribute significantly to the containment of a fire.

- a U-shaped recess 21 is provided, in which a scraper 22 for sealing the fire protection door 1 is inserted in the closed state.
- the scraper 22 interacts with a threshold 23 which is let into the floor.
- Both the side walls 3 and the lintel wall 4 of the frame 3 have an undercut recess 24 on their surface facing the door leaf 6, into which sealing elements 25 are inserted, which expand when the temperature rises due to a fire.
- the frame 7 has undercut recesses 26 on its surfaces facing the frame 2, which run in the vertical and horizontal directions, with an inserted sealing element 27, which also expand when the temperature rises due to a fire.
- Such a sealing element 25, 27 is available on the market, for example, under the trademark Thelesol.
- the sealing elements 25 and 27 expand in such a way that the spaces between the frame 7 of the door leaf 6 and the frame 2 are completely filled and the door leaf 6 is clamped in the frame 2, so that the door leaf 6 still then is held in the frame 2 when the door hinges 9 are destroyed or significantly damaged.
- a bolt 28 is arranged between the door leaf 6 and the side wall 3 of the frame 2 in the region of the door hinges 9, which has a conical end 29 and at its end opposite the conical end 29 has a thread 30.
- the bolt 28 is screwed into a bore formed in the frame 7 of the door leaf 6 with an internal thread.
- the conical end 29 of the bolt 28 engages in a corresponding bore within the side wall 3 of the frame 2, so that the door leaf 6 not only via the sealing elements 25 in the case of door hinges 9 destroyed or damaged by fire and 27 is held in the frame 2, but also via the bolt 28 and the closing element 12.
- the bolt 28 and the closing element 12 prevent the door leaf 6 from sagging in the direction of the threshold 23, so that the fire protection door leaks in the area between the lintel wall 4 and door leaf 6 after expansion of the sealing elements 25 and 27 can be prevented.
- holding elements 32 are arranged both in the region of the door hinges 9 and in the region 31 between the door hinges 9 of the fire protection door 1.
- These holding elements 32 consist of a flat steel strip which is bent twice in the opposite direction in its central region, so that the two ends 33 and 34 of the holding elements 32 run parallel to one another.
- the holding elements 32 are pushed into openings 35 in the area of the frame 7 of the door leaf 6 and fastened on the inside of the frame 7 of the door leaf 6.
