    In the solution presented, the outer surfaces of the front door comprise a material which may consist, for example, of laminate, plastic, gias fiber or composite, such as wood / plastic grain post, or of a sheet of recycled material. Preferably, the outermost surfaces comprise metal plate, preferably steel plate. The use of a standing material or a corresponding material makes the front door strong and durable and can improve the front door's fire safety properties. Between the outermost surfaces of the outer door is placed at least one insulating layer which preferably comprises polystyrene, polyurethane after some suitable insulating wool. Preferably, the isotering layer comprises cast polyurethane, since cast polyurethane has particularly good thermal insulation properties.
    According to a favorable example, the outer door comprises a further plasterboard which can be placed tilt the example between the surface layer of the inner side of the outer door and the surface layer of the outer side of the outer door. One such solution is, for example, to place the gypsum board between the surface layer of the inner side of the outer door and a potyurethane layer which acts as insulation.
    The addition of the gypsum board can improve both the fire safety properties of the front door and the sound insulation properties of the front door.
    According to a favorable example, the outer door comprises a special cooling interruption threshold which is preferably in communication with the joint between the surface layer of the inner side of the outer door and the surface layer of the outer side of the outer door. This cooling interruption threshold suitably comprises a gap between these two surface layers, in which a seal has preferably been placed.
    According to a dreary example, the seal of the front door essentially surrounds all the ends of the front door. According to a favorable example, the seal is formed by a profile seal suitable for the door, which can be continuous. According to another advantageous example, the seal is a continuous, non-annular seal. According to one example, the seal is clamped around the ends of the front door, preferably in connection with the cooling interruption threshold. The inventive exterior door is presented in the independent claim 1. Some advantageous embodiments of the exterior door are presented in the dependent claims 2-5.
    Description of drawings The invention will be described in more detail in the following with reference to the accompanying drawings, in which: shows an exterior door according to an embodiment, obliquely seen from above, Figures 2a-b show some examples of how the structure of the exterior door according to Figure 1 can be realized, in cross-sectional views, Figures 3a-b show some examples of joints of an exterior door according to Figure 1 and the door frame, and show an example of the cross-section of a seal in an exterior door according to Figure i. 4 Figure 4 Description of the invention in detail In this application the terms the surface layer2 of the inner side of the outer door, i.e. the first surface layer 2, and the surface layer 3 of the outer side of the outer door, i.e. the second surface layer 3. Both of these terms stand in this application for the substantially outermost layers of the front door, i.e. the exterior door's so-called outer shell. The term surface layer 3 of the outer side of the outer door is in this application closer to the side of the outer shell of the outer door 1 which is intended to be placed as the so-called outer door 1. outer side, i.e. on the side which, in the normal use of the front door, is on the outside of a building. The term surface layer 2 of the inner side of the outer door stands in this application for the side of the outer shell of the outer door 1 which is intended to be positioned as the so-called outer door 1. inner side, i.e. on the side which in the normal position of use of the front door is located on the inside of a building. The outer door 1 can in some cases also be installed in such a way that the surface layer 3 on the outer side of the outer door is placed as the inner side of the outer door and the surface layer 2 on the inner side of the outer door 1 is placed as the outer side of the outer door without changing the invention.
    The figure shows a solution according to an example of the outer door 1. The figure shows an outer door 1, the surface layer 2 on the inner side of the outer door comprising end surfaces 2a on the surface layer of the inner side (ie the first end surfaces 2a) and a door panel 2b, the surface layer 3 on the outer side outer side comprising surface surfaces 3a on the surface layer of the outer side (ie the other end surfaces 3a) and a door panel 3b, a cooling break sill 6 preferably comprising a seal 7, a window 8t the outer door, the outer door fastener 9, and a place 10 for the front door locking device.
    The outer door i comprises the surface layer 3 on the outer side of the outer door, the surface layer 2 on the inner side of the outer door, and at least one insulating layer which is substantially located between them. Both surface layers of the outer door can be divided into the actual door panel 2b, 3b and four ends 2a, 3a, which four ends of the outer door comprise both the end parts 3a on the surface layer 3 of the outer side and the gift parts 2a on the surface layer 2 of the inner side.
    The door panel 2b, 3b stands in this application, according to figure 1, for the two largest surfaces of the front door, independent of e.g. how many parts does the so-called the door panel 2b, 3b consists of or if the surface layer 2a and 2b of the inner side (or the surface layer 3a, 3b of the outer side) consists in its entirety of one or more material panels.
    Between the ends 3a of the surface layer 3 on the outer side of the outer door and the ends 2a of the surface layer 2 on the inner side of the outer door, a gap is preferably provided which in this application is called a cooling break 6. The cooling break 6 preferably consists of a gap between the end surfaces 2a, 3a of metal, which gap extends from the outer shell 2, 3 of the outer door 1 all the way to the insulating layer of the outer door (ie the intermediate layer of the outer door) 4, 5 (Figure 2b). In the case of the cooling break 6, there is no material at all of the outer shell of the outer door, such as for example metal, due to the weak heat transfer between the surface layer 2 of the inner side of the outer door and the surface layer 3 of the outer side of the outer door is usually retarded. The cooling break 6 preferably surrounds all ends 2a, 3a of the outer door 1, and it is preferably provided with the seal 7 of the outer door. The seal 7 can be made of any suitable sealing material. The purpose of the seal 7 placed in the cooling gap 6 is to further delay the heat transfer between the surface layer 2 of the inner side of the outer door and the surface layer 3 of the outer side of the outer door. The seal will be described in more detail in connection with Figure 2b.
    The described front door 1 may comprise - in addition to that presented above - also other known solutions and devices, such as preferably at least devices for opening and closing the door and typically also devices for reading the door at the door locking device 10. In addition, the front door comprises 1 typically the outer door fasteners 9, which are intended to attach the outer door to frames 11 (shown in Figure 3) which surround the outer door in a suitable manner so that the outer door 1 can be opened and closed if necessary.
    The front door typically eats a folded door, but this is not necessary. In addition, the outer door 1 can also comprise other solutions, such as, for example, a window 8 shown in Figure 1, which may be, for example, a sliding window or a corresponding solution. The shape and size of the window 8 that may be attached to the front door may vary. These above-mentioned properties can be realized in a suitable manner according to the prior art, and they do not need to be described in more detail in this application.
    Figures 2a and 2b show some examples of realizations of the exterior door structure according to figure 1 in cross-sectional views. The figures show the surface layer 2 on the inner side of the outer door, comprising a gable 2a and a door panel 2b, the surface layer 3 on the outer side of the outer door, comprising a gable 3a and a door panel 3b, a first insulating layer (ie the first intermediate layer) 4, and a cooling break threshold 6 Figure 2b further shows a second insulating layer (ie the second intermediate layer) 5, as well as a seal 7 which is preferably placed in the cooling interruption threshold.
    The surface layer 3 on the outer side of the outer door 1 and the surface layer 2 on the inner side preferably consist of a material, which may be, for example, laminate, plastic, glass fiber or composite, such as for instance wood / plastic composite, or a slice of recycled material. Preferably, the outermost surfaces comprise sheet metal, preferably sheet steel. According to one embodiment, the surface layer 3 on the outer side of the outer door and the surface layer 2 on the inner side for the most part consist of steel plates, preferably they consist essentially in their entirety of at least one steel plate. Sheet steel is an advantageous material for the outer shell outer shell, as it gives the outer door good needle strength and durability properties, and it is not flammable.
    The outer door 1 comprises at least one insulating layer 4 which preferably consists of polystyrene, polyurethane or any suitable insulating wool, such as for instance plastic or mineral wool or wood fiber insulation. Preferably, the insulating layer consists of molded polyurethane, such as, for example, injection molded polyurethane. Cast polyurethane gives the front door a particularly good thermal insulation capacity relative to the thickness of the front door, so polyurethane is preferably added to the front door in molded form.
    Polyurethane foam can be cast into the scales 2, 3 of the outer door 1, for example by means of a casting strip. Also in this fail, between the end wall 2a of the surface layer 2 on the inner side of the outer door and the end surface 3a of the surface layer 3 on the outer side, a suitable gap is preferably left, i.e. the cooling interruption threshold 6 shown in Figure 2a, in which a seal 7 can be fitted according to Figure 2b.
    The seal 7 shown in Figure 2b can be placed either so that it fills the gap formed by the cold break threshold 6 substantially in its entirety in the deep direction, or so that it fills in the deep direction only a part of the crack formed by the cold break threshold 6. Preferably extends the seal placed in the cooling interruption threshold 6 in the deep direction substantially all the way to the insulation layer 4 of the outer door. In the width direction, the seal 7 preferably covers the cooling interruption threshold 6 substantially in its entirety.
    The seal 7 preferably surrounds the entire outer door 1, preferably by staying substantially in the area of the ends 2a, 5a. The seal 7 is preferably a continuous non-annular seal, the length of which is preferably chosen so that the seal is tightened tightly in the opening formed by the cooling interruption threshold 6. The seal 7 can preferably also be a profile seal. Such a profile seal can either be a continuous sealing profile or consist of several parts. The seal 7 can be placed in the cooling break sump 6 either so that the seal 7 remains in the gap 6 only by means of its above-mentioned suitable length and the tension which it causes, or the seal 7 can in addition or instead also be fastened in another suitable way, such as for example by gluing. When using a favorable o-ring shape of the seal, the preferably tensioned remaining seal 7, over the entire length of the seal, is affected by forces in the direction of the cooling interruption threshold, i.e. in particular such an o-annular seal 7 is preferably designed according to figure 2b in such a way that the end of the seal 7 which becomes outside the cold break threshold 6 is preferably substantially wider than the width of the cold break threshold 6. Such a location and design can This is done in particular when it is desired to ensure that the seal 7 is not displaced in its entirety into the cooling interruption threshold 6 under the influence of any said forces.
    The above-mentioned sealing solution has several advantages. The advantageous o-annular seal can be held in place particularly well, thanks to forces which affect it in the deep direction, against the insulating layer 4. In addition, the placement of the seal 7 close to the cooling breakage threshold 8 can increase the insulating properties of the outer door.
    The cooling interruption threshold 6 is preferably at least 1 mm wide, for example 1-8 mm wide. In a more advantageous manner, the cooling interruption threshold is 2-6 mm wide or 3-5 mm wide. The width of the cooling interruption threshold in this application represents the average distance between the surfaces 2a and 3a at the cooling interruption threshold 6. Preferably, the cooling interruption threshold 6 has substantially the same width over its entire length, but the width of the cooling interruption threshold can also vary if necessary. The cooling interruption threshold 6 is preferably as deep as it is wide, but this is not necessary. As mentioned earlier, it is advantageous to provide the outer door with the cooling interruption threshold, especially between the surface layer 2 of the inner side and the surface layer 3 of the outer side, especially between the ends 2a, 3a, because the surface of the outer door , especially in the case that the surface of the front door consists of metal, shall otherwise easily conduct heat, for example from the inside to the outside. In this case, the surface of the front door can also feel bare. The cooling interruption threshold is placed substantially for the largest part, preferably substantially in its entirety, between the end surfaces 2a, 2a of the outer layer (outer shell) of the outer door. In a preferred embodiment of the invention, at least one insulating layer 4, 5 of the outer door 1 preferably comprises gypsum, which is preferably in the form of a gap plate. Preferably, the gap is placed in the outer door 1 so that it is located substantially between the surface layer 2b of the inner side of the outer door and the surface layer 3b of the outer side of the outer door. At least one gypsum board may be placed, for example, between the surface layer 2b, 30 of the outer door 1 and the insulating layer 4, such as, for example, a polyurethane insulating layer. Preferably an insulating layer containing gypsum, preferably a gypsum board, is placed between the surface layer 2b of the inner side of the outer door 1 and the insulating layer 4, such as for example a foamed polyurethane insulating layer (the second insulating layer 5 in figure 2b). The outer door may comprise several insulating layers or intermediate layers 4, 5, which may consist - instead of or in addition to polyurethane and plaster - of any other suitable material.
    The fire safety properties of the front door according to the invention are good, thanks to the materials used in the outer shell 2, 3 of the door, since for example steel sheet, which is preferably used in the front door, is not flammable. In addition, the gypsum board preferably installed in the front door further improves the fire safety of the front door even more. Gypsum boards can be added in the front door either only between one or both surface layers 2, 3 and the insulation layer, and if necessary also between two or several insulation layers. The fire safety increasing effect of the gypsum board is emphasized especially in the case where the gypsum board is placed as the layer next to the surface layer 2b of the inner side of the outer door, or at least before the insulation layer which resists fire worse, such as a polyurethane insulation layer. It is advantageous to provide the outer door according to the invention with a layer of a gypsum board in addition to the fire safety properties also because the gypsum board has good sound insulation properties.
    The sound insulation properties of the exterior door can be significantly improved, thanks to the gypsum board that is added to the door. In addition to the above-mentioned properties, a plasterboard that is added to the front door can also give a high-heeled impression compared to a regular door.
    In some cases it may be advantageous to improve the dimensional durability of the front door, especially when matter is used in the front door! with particularly different thermal expansion properties in the surface layers 2, 3 and in the frames 11, t1b of the outer door (shown in Figures 3a, Bb). In this case, it may be advantageous to provide the front door with a special solution that improves dimensional durability. According to an embodiment of the invention, the outer door can be provided with a suitable insulating layer which in some cases can be, for example, an intermediate layer 5 which comprises a plasterboard. In this case, the dimensional stability of the front door can be improved, thanks to the said suitable melian layers. In addition, such a special solution, for example with a plasterboard, can in some cases have a favorable effect so that the front door remains in the required shape (ie it does not become curved, for example) even though there may also be large temperature differences on the outside and inside of the front door. According to an embodiment of the invention, at least one intermediate layer 4, 5 of the outer door comprises a sheet layer which is at least twice as thick as the thickness of the surface layer 2, 3 of the outer door.
    Preferably, this meilan layer 4, 5 of a top layer is substantially in communication with at least one surface layer 2, 3. The purpose of this is to act in such a way that the outer door stays better in the requested shape.
    Figures 5a and 3b show some advantageous examples of how the door fits into the door frame t1 and the door sill 11b. The figures show bLa. the surface layer 2 on the inner side of the outer door, comprising a gable 2a and a door panel 2b, the surface layer 3 on the outer side of the outer door, comprising a gable 3a and a door panel 3b, an insulating layer 4, a cooling break threshold 6, and the door frame 11 and sill 11b.
    Figure 3a shows a situation in which the outer door is closed so that the outer door is substantially placed against the frame 11. In this case, the end 2a, 3a of the outer door is preferably located substantially close to the frame 11.
    To this density is contributed by the addition of a seal 7 (shown in Figure 2b). Figure 3b again shows a situation in which the lower part of the outer door 1 and the threshold 11b associated with the end of the lower part are seen. Even in this situation, the front door is preferably located substantially close to the threshold rail 11b. The tightness can be further improved by providing the cooling break sump 6 with a seal 7 (shown in Figure 2b).
    The alternatives according to Figures 3a and 3b show only a few possible solutions for shapes of the door ends 2a, 5a and for shapes of the frame 11 and the sill 11b, with also differently useful solutions being satisfactory.
    Figure 4 shows an example of the cross section of a seal 7 for the front door according to figure 1.
    When the seal 7 is added to the cooling gap 6 of the door (shown in Figure i) (shown in Figure 2b), preferably the part 7b of the seal 7 placed substantially inside the cooling gap is preferably pressed together at least partially, by enabling a particularly tight insulation for the cooling of the outer door. interruption. Said part 7b of the seal 7 shown inside the cooling gap, which is shown inside Figure 4, is intended to be placed preferably substantially in its entirety in the cooling break of the outer door. In this case, said part 7b of the seal 7 located substantially in the cooling break preferably comprises one or more projections which are compressed, preferably under the influence of the walls of the cooling break. This can improve the thermal insulation capacity of the front door.
    The part 7a of the seal 7 which preferably remains at least partially outside the cooling break is preferably designed such that, due to its shape, the seal 7 remains partially outside the cooling break. The removal of the seal is at least partially pressed together between the front door and the front door frame 11 and the sill 11b (shown in Figures 3) when closing the front door, in such a way that a highly compressive tight joint is formed, thanks to the seal 7. The parts 7a and Tb of the seal may be substantially equal in their space and / or surface, or they may be substantially different in size in their space and / or surface.
    The shape of the seal shown in this figure 4 is only a possible embodiment of the seal, and in the invention different seals according to the prior art can also be used.
    The outer door according to the invention can have a good thermal insulation capacity, good fire safety properties, good pour strength and durability properties as well as good dimensional resistance. It can be manufactured in a cost-effective way, since its production can, if necessary, be largely automated with solutions according to the known technology. The presented front door can be manufactured in a modified manner, for example so that the surface layer of the front door consists of several different boards, or for example so that the surface layers of the front door according to the invention can be painted and / or surface treated with one or more materials, and / or treated on some other requested method without changing the inventive idea. In this way, the invention is not limited only to the examples presented in Figures t ~ 4 and in the description above, but instead the invention is characterized by what is to be presented in the following claims.
