Definitions

  • the invention relates to a method for producing a door leaf for a door designed as a fire closure, and to a door leaf for a door for forming a fire closure, which is produced in particular using such a method.
  • Door leaves can be manufactured using various methods.
  • door leaves for example, in the so-called box-cover construction, in which a door leaf filling is placed loosely in a box, and then a cover is firmly connected to this box. The individual parts of the door leaf are then held together by a connection between the box and the cover, for example along the edge regions.
  • box-cover construction in which a door leaf filling is placed loosely in a box, and then a cover is firmly connected to this box. The individual parts of the door leaf are then held together by a connection between the box and the cover, for example along the edge regions.
  • door leaves in a sandwich construction, wherein a plurality of approximately equally large plates are integrally connected to one another and thereby form a plurality of layers with different functions along a depth direction of the door leaf.
  • a door leaf is for example in EP 2 241 713 A2 described.
  • a door construction for an inner or outer door with a door leaf with frame elements is known, the frame elements being held together without the use of screws, bolts or fastening means.
  • the door leaf is provided with embossed panels and a molded, heat-insulating core made of polystyrene.
  • a method for producing an embossed door leaf for a door forming an outer end of a building is known, the door leaf being designed to be much lighter than embossed door leaves with steel sheets which have been filled with PU foam, and to be less expensive to manufacture.
  • PVC panels are hot-pressed to form a broad-side contour.
  • a filler material made of a solid polystyrene is burned under pressure in hot plates into a filler material mold that is complementary to the broadside contour. The panels and the fill material are then glued together with interlocking contours.
  • the EP 2 535 473 A2 discloses spraying a fire protection door filled with a fire protection plate made of bound mineral wool with a fire protection agent, such as expanded graphite, in places, the amount of the fire protection agent applied varying depending on the application site.
  • a fire protection agent such as expanded graphite
  • the BE 894 486 A discloses to use an insulation layer made of mineral wool in combination with an outer plastic plate to improve the fire resistance of a door leaf with an embossed broadside contour.
  • the object of the invention is to propose a method for producing a door leaf embossed with a broad side contour, which can be carried out inexpensively in large series and can perform an improved fire protection function. A corresponding door leaf is also to be created.
  • a door leaf that is produced in particular with such a method is the subject of the independent claim.
  • a mineral wool mat is used as the mat-shaped filling material.
  • a door leaf should have the lowest possible fire load.
  • a filler material in the form of a mat is therefore not simply introduced into an interior of the door leaf in the form of an unstructured mat, but rather a separate prefabrication step is carried out in which a predefined mat shape contour is embossed on the filler material.
  • This mat shape contour essentially corresponds to the broadside shape contour, which was likewise introduced into the forming plate in a prefabrication step, and is also arranged in the same position in the assembled state of the door leaf.
  • the structures of the mat shape contour and the broad side shape contour thus interlock, which is why the mat shape contour also complements the broad side shape contour.
  • a tight connection of a forming plate, which defines the outer broad side of the door leaf, and the filling material is thus possible without further manufacturing steps having to be carried out. This enables significant cost savings in the manufacture of the door leaf.
  • the door leaf is thus preferably also designed as a door leaf for a door designed as an external closure of a building.
  • a steel sheet is used as the flat forming blank, the predefined broadside contour being stamped in using a standard stamping method.
  • Steel sheets are particularly inexpensive and therefore particularly advantageous from the cost point of view to form the forming plate that defines the outer broad side of the door leaf.
  • the forming blank can also be a composite panel, in particular a composite panel made of glass fiber-reinforced plastic, the predefined broadside contour being stamped in by a hot pressing process.
  • a mineral wool mat is used as the mat-shaped filling material.
  • a web-reinforced mineral wool mat is preferably used.
  • Mineral wool mats are particularly advantageous if the door leaf is to be used for closing a fire, since mineral wool represents a low fire load on the door leaf due to the non-combustibility.
  • it is particularly advantageous to use web-reinforced mineral wool mats since these have their own stability and can therefore be easily glued, for example, inside the door leaf without additional internal reinforcements having to be provided.
  • Such web-reinforced mineral wool mats can be purchased from Rockwool, for example.
  • the predefined mat shape contour of the mat-shaped filling material is introduced into the mat-shaped filling material by an embossing process or by a milling process.
  • embossing process is particularly advantageous here. This is because simply replaceable negative molds can be used on a standard stamp, which, depending on the shape that is to be embossed into the mat-shaped filler material, are used.
  • a cassette contour is preferably embossed as the broadside contour and as the mat contour, the embossing taking place in particular as a recessed relief. This advantageously gives the door leaf a particularly delicate appearance.
  • the recessed relief of the mat shape contour advantageously has a depth which is 20% to 25% greater than a depth of the recessed relief of the broadside shape contour.
  • the mat-shaped filler material usually has a certain springback behavior, which is advantageously taken into account when introducing the predefined mat shape contour. Therefore, the recessed relief of the mat shape contour is introduced with a greater depth than that of the broadside shape contour. Tests have shown that a difference of 20% to 25% in depth is sufficient, so that after the forming plate and the mat-shaped filler material have been put together, a direct, close contact between the two materials is possible.
  • the forming blank and the mat-shaped filling material are preferably joined together in such a way that the broad-side shape contour and the mat shape contour come into flush contact with one another. This is particularly advantageous when using the door leaf as a fire barrier, since this advantageously prevents the occurrence of larger joints within the door leaf.
  • a box is preferably formed from a first forming plate, a lid being formed from a second forming plate, the mat-shaped filling material being inserted into the box when the forming plates and the mat-shaped filler material are joined together, and the box is then closed with the lid. It is particularly advantageous if both forming plates and both sides of the mat-shaped filling material each have a contour that can interlock.
  • the forming plate and the mat-shaped filling material are preferably joined to form a sandwich plate, the forming plate and the mat-shaped filling material in particular being glued to one another.
  • the door leaf has at least one outer plate for forming an outer broad side of the door leaf, the outer plate having a broad side shape contour in a predetermined area.
  • the door leaf also points a mat-shaped filling material, which has a mat shape contour in a predetermined area.
  • the outer board and the mat-shaped filler material are assembled to form the door leaf.
  • the broad side shape contour and the mat shape contour are designed to be complementary to one another, so that the broad side shape contour and the mat shape contour interlock.
  • the broad side contour and the mat contour are each formed as a recessed relief.
  • Fig. 1 shows a front view of a door leaf 10, which can be used, for example, for a front door designed as an outer end of a building, but also for a fire end.
  • the door leaf 10 has a special broad side contour 14 on an outer broad side 12, which in the present embodiment is designed as a cassette contour 16 and in particular as a recessed relief 18, ie deformed to form an inner region of the door leaf 10.
  • the cassette contour 16 has four cassettes, it However, it is also possible that in an alternative motif design, more or fewer cassettes are formed on the door leaf 10.
  • the cassette contour 16 is located on a predetermined surface area 20 of the door leaf 10.
  • Fig. 2 shows a first embodiment of the door leaf 10 in a cross-sectional view along the line AA in Fig. 1 , where in Fig. 2 the door leaf 10 is constructed as a sandwich plate 22.
  • Sandwich panels 22 are distinguished by the fact that they have a plurality of layers 26 along a depth direction 24 of a door leaf 10, the layers 26 being integrally bonded and thus immovably connected to one another.
  • a filling material 28 is provided as a first layer 26, outer boards 30 of the door leaf 10 forming a motif plate 32 and integrally, e.g. by gluing, are connected directly to the filling material 28.
  • FIG. 2 The embodiment shown shows such a sandwich panel 22, in which a mat-shaped filler 28, for example in the form of a mineral wool mat 34, is arranged between two outer boards 30, which form the outer broad sides 12 of the door leaf 10.
  • a mat-shaped filler 28 for example in the form of a mineral wool mat 34
  • a first outer board 30 is formed as a flat outer board 30 without any motifs therein.
  • a second outer board 30, however, has a broad-side shape contour 14 at a predetermined surface area 20, specifically that in FIG Fig. 1 shown cassette contour 16. In Fig. 2 it can be seen that it is designed as a recessed relief 18.
  • the mat-shaped filling material 28 also has a corresponding mat shape contour 36, which is complementary to the broad side shape contour 14 in the outer plate 30, so that the wide side shape contour 14 and the mat shape contour 36 can interlock.
  • the mat shape contour 36 and the broadside shape contour 14 are introduced into the mineral wool mat 34 or the outer plate 30 before the individual layers 26 are joined together, as will be explained below with reference to Fig. 3 is described.
  • Fig. 3 shows a schematic flow diagram of a method for manufacturing a door leaf 10.
  • At least one forming plate 38 for forming a later outer plate 30 of the door leaf 10 and a mat-shaped filler material 28 are provided.
  • the forming plate 38 can be provided, for example, as a flat steel sheet 40.
  • a composite plate 42 as the forming plate 38, which comprises a glass fiber reinforced plastic.
  • a mineral wool mat 34 is provided as the mat-shaped filling material 28, in particular a web-reinforced mineral wool mat 34 is used which has inherent stability, so that further reinforcements within the door leaf 10 can be dispensed with.
  • the broad-side shape contour 14, for example the cassette contour 16 is then correspondingly in a predetermined surface area 20 of the forming plate 38 Fig. 1 embossed. This is done using a simple steel sheet 40 by a standard stamping process. However, if a composite panel 42 is used, this is done by a hot press process.
  • the mat-shaped filling material 28 is now also pre-processed, namely in that the mineral wool mat 34 is also embossed with the cassette contour 16 as a mat shape contour 36.
  • the molding contours 14, 36 are each stamped in as a recessed relief 18, the mat molding contour 36 having a greater depth T 1 during stamping than a depth T 2 of the broad side molding contour 14 on the forming plate 38.
  • the depth T 1 in the mineral wool mat 34 is 20% to 25% greater than the depth T 2 in the forming plate 38.
  • the shape contours 14, 36 are then embossed into the mineral wool mat 34 or the forming plate 38, at the end of the process the forming plate 38 and the mat-shaped filler material 28, ie the mineral wool mat 34, are joined together in such a way that the broad side contour 14 and the mat contour 36 interlock.
  • the assembly can be done accordingly Fig. 2 in a sandwich plate 22, for example by gluing.
  • a PU adhesive can be used.
  • the door leaf 10 has a broad side contour 14 only on one outer broad side 12, but it is also conceivable to also provide such a broad side contour 14 on the opposite outer broad side 12.
  • a sandwich plate 22 it is also possible to design the door leaf 10 in a box-cover construction, a first forming plate 38 forming the box 44, while a second forming plate 38 forms the cover 46.
  • Such a box-lid construction is in cross section along the line AA in Fig. 1 in Fig. 4 shown, however, the representation of the broadside contour 14 has been omitted.
  • the door leaf 10 has a corresponding one Broad-side shape contour 14 or a mat shape contour 36, wherein the shape contours can be present both in the cover 46 and in the box 44.
  • door leaves 10 for, for example, fire protection doors, but also for front doors, both in composite and steel construction, in which a prefabricated mineral wool mat 34 with contour shapes based on the motifs of the door leaf 10 is used.
  • the fire load in particular in the case of composite or steel doors, and also the costs can be significantly minimized, since in comparison to previously used phenolic resin plates or foam plates, which are quite expensive, simply a mineral wool mat 34 is simply used.
  • a mineral wool mat 34 is simply used.
  • This mineral wool mat 34 is first shaped.
  • the mineral wool mat 34 initially has a uniform bulk density and a separate prefabrication step takes place, the desired mat shape contour 36 being embossed.
  • the individual outer boards 30 are also punched or embossed if steel or metal is used, or pressed correctly if a composite material is used. Then the mineral wool plate 34 is embossed using appropriate negative forms and these negative forms are embossed. Finally, the mineral wool mat 34 is inserted and glued.
  • the mineral wool has a certain springback behavior, which is why the mineral wool is more strongly shaped than the sinkers.
  • the mineral wool mat 34 has a thickness of 40mm, and the broad side contour 14 should protrude by 9mm into an interior of the door leaf 10, 2mm is added to this depth T 2 in order to compensate for the springback behavior of the mineral wool mat 34. If an embossing of 9 mm is to be adjusted accordingly, the embossing in the mineral wool mat 34 is embossed 11 mm deep.
  • the outer boards 30 are embossed with cassettes, which is a popular design for front doors in the English-speaking world, it being possible, for example, to emboss four cassettes, but also six cassettes or any shape contours.
  • the cassettes or other motifs that are inserted are embossed on the inside, i.e. as a sunk relief 18.
  • Web-reinforced mineral wool mats 34 are advantageously used, since these have their own stability and can be glued. If a door, for example in a box-lid construction, is filled with such mineral wool, further reinforcement is no longer necessary. It is also known to introduce such comparable web-reinforced mineral wool in sandwich doors and then to use them as an exterior door.
