    15 20 25 30 2 Thus, for a period, a construction technique has been used on houses and properties, which means that the body of the house is covered with cellular plastic and some form of surface structure. The cellular plastic is then glued directly to a building board or cover board which may consist of plaster or chipboard and is in turn attached to an insulated set of regulations. In the current construction, there is no traditional air gap, which has meant that moisture that comes inside the facade does not come out. The moisture stays in the wall construction and forms mold and rot.
    Corresponding problems also exist in stone houses where the same method of cladding the façade has been used. The moisture is absorbed in the basic construction and further up in the walls of the house. If the house is not sufficiently ventilated, the moisture from the household and foundation remains in the walls and can cause mold and cause allergies.
    The most common known method used to remedy the mentioned problems is simply to tear or dismantle the entire wall from the outer structure to the regulations and the load-bearing structure. Regardless of whether only a small part of the house is damaged, all materials are removed. An ocular inspection is then performed for further disassembly and replacement of damaged parts. It is a very labor-intensive method that entails extensive environmental impact and a poor working environment. Disassembly according to known technology results in large amounts of smaller pieces and dust of plaster and cellular plastic, which deteriorates the working environment and causes litter in the immediate area. Often a wind foil or cardboard that is inside the building board is also destroyed.
    A disadvantage of methods for at least partially dismantling a wall with a foam layer of known technology arranged on a substrate is that they are labor-intensive.
    A problem with such methods of known technology is that they have a relatively extensive negative environmental impact and a poor working environment.
    Another problem with such prior art methods is that they are costly.
    Another disadvantage of such prior art methods is that they are inefficient. 10 15 20 25 30 3 SUMMARY OF THE INVENTION An object of the invention is to avoid the above-mentioned disadvantages and problems of the prior art. The method, device and system in accordance with the invention provide an improved working environment and facilitate source sorting of materials when dismantling a wall. The invention further entails a less labor-intensive, more environmentally friendly and more cost-effective renovation of moisture-damaged facades of, for example, single-stage sealed outer walls. The invention entails a considerably shortened working time for removing a facade or parts of a facade. The invention also entails a considerable saving of material. In addition, the invention entails considerably less littering when dismantling the various layers of a façade. In addition, the damage to the façade is significantly less than when using conventional methods. At the same time, it is not required that the house is covered with tarpaulins or the like to the same extent to prevent littering and dust spreading.
    The invention relates to a method for at least partially dismantling a wall with a foam layer arranged on a substrate, characterized by the steps of arranging a first groove at least substantially transversely through the foam layer, at a distance from the first groove arranging a second groove at least substantially transversely through the foam layer, and by means of a heating wire cut from the first groove to the second groove along a plane of the foam layer and through a portion of the foam layer arranged at the substrate.
    The method according to the invention may also comprise the steps of making at least the second groove with a width substantially corresponding to or greater than a heating wire supporting arm, the heating wire being applied to the portion of the foam layer arranged at the base, and the heating wire supporting arm being inserted in the second groove and is passed along it while entraining the heating wire along the portion of the foam layer arranged at the substrate in order to cut off at least a substantial part of the foam layer from the substrate by melting. The grooves can be arranged across the foam layer and a plaster layer arranged on the foam layer. The plaster layer can be removed before the removal of the foam layer or at the same time.
    Peeling off the foam layer from the wall usually involves a number of steps.
    Part 1 The surface layer of the façade can be cut up with grooving machines in the form of a jigsaw or a jigsaw so deep down to the substrate where the foam is attached. The grooving machines can be equipped with specially adapted diamond blades that have a groove width of, for example, 1-20 mm, preferably 2-10 mm, preferably 3-5 mm and, for example, about 4 mm so that the heating wire can then come down or into the construction. The track machines can be equipped with a connection to a vacuum cleaner so that dust particles do not spread during disassembly.
    You can conveniently start by derailing the knot corners and dismantling them by hand. Sheet metal fittings and other objects can also be removed. You can also saw with the track machines up along the eaves, around windows and down at the façade foot if needed. Thereafter, the wall can be traced in a number, for example at least substantially parallel, tracks. For example, the wall is traced so that a mutual distance of the grooves does not exceed the length of the heating wire and thus forms sections which are not wider than the length of the heating wire. The grooves can, for example, be applied vertically, horizontally or in the form of a checkerboard pattern.
    Step 2 If necessary, the plaster layer can be removed from the foam layer before removing the foam layer from the substrate. The grooves are applied, for example, through the foam layer and the plaster layer arranged on the foam layer, after which the plaster layer can be peeled off from the foam layer in sections which are substantially delimited by the grooves. Thus, the plaster layer can be separated from the wall for further handling, source sorting or disposal. For example, sections of the plaster layer are pulled off from the foam layer manually. Step 15 For example, foam layers in the form of EPS sheets and the like can be connected to the substrate by means of fastening devices arranged through the foam layer. Existing fasteners are exposed upon removal of the plaster layer or sections thereof. The exposed fasteners for connecting the foam layer to the substrate are removed if necessary. For example, fasteners arranged through the foam layer can be unscrewed or pulled out with a suitable tool, such as a screwdriver, drill, crowbar or the like.
    Step 4 To remove the foam layer, use the heating wire or a thermal knife and in some contexts also chemicals to dissolve or melt away the foam. The foam layer is removed, for example, by means of the heating wire to form sections of the foam layer, whereby the foam layer can be sorted at source and disposed of in an environmentally friendly and efficient manner.
    Part 5 After disassembly, residues of adhesive and cellular plastic of 1-2 mm may remain. If these need to be removed, it is fine with the heating wire or the thermal knife or with solvents such as acetone or methyl ethyl ketone. The surface can also be cleaned by means of a grinding machine, which can be connected to a vacuum cleaner for collecting dust in a conventional manner. When this optional part of the method has been performed, inspection and moisture search can be performed before further measures are taken.
    In some cases, inspection and moisture search, such as by means of conventional moisture measurement methods, result in one or more boards of the substrate, such as gypsum or chipboard, having to be replaced. Step 4 and step 5 as above expose the fasteners that connect the base to a set of rules, after which the fasteners can be removed. For example, the fasteners are removed by means of a machine to remove the fasteners by mechanical machining, such as by milling or sawing. After removal of the fasteners, the substrate or parts thereof can be removed from the regulations for further handling, such as source sorting. The invention also relates to a device for removing a foam plastic layer from a substrate during at least partial disassembly of a wall, characterized in that the device comprises a body with a first arm projecting from the body, one on a distance from the first arm arranged and projecting second arm and a heating wire extending between the arms for cutting cellular plastic by melting, the heating wire by means of the arms being arranged at a distance from the body while forming a space therebetween for receiving at least a substantial part of a thickness of the foam layer when cutting through a portion of the foam layer arranged in connection with the substrate. Thus, the space is designed so that the body can run outside the foam layer at the same time as the heating wire, via the arms, can run inside the foam layer, at the building board or through a portion of the foam layer at the building board.
    The heating wire can be arranged at a distance from the body which substantially corresponds to or is greater than a total thickness of the foam layer and the plaster layer arranged thereon, so that the body can run outside the plaster layer while the heating wire, via the arms, can run inside the plaster layer. layer and through the foam layer at the substrate.
    The invention also relates to a system for at least partially dismantling a wall with a foam layer arranged on a substrate, characterized in that the system comprises a tracking machine with a blade made for tracing across the foam layer and a plaster layer arranged thereon and a device according to the above , the width of the blade corresponding to or greater than a width of at least the other arm of the device.
    The wall can be a single-stage sealed wall, such as a plastered, single-stage sealed rule wall, the base being a building board in the form of a plasterboard, chipboard or the like. Alternatively, the wall may be another type of single-stage sealed wall, such as a single-stage sealed stone wall, the substrate being stone or concrete.
    Further features and advantages of the present invention will become apparent from the description of exemplary embodiments below, the accompanying figures and the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with the aid of exemplary embodiments with reference to the accompanying drawings, in which Fig. 1 is a schematic cross-sectional view of a plastered, single-stage sealed rule wall, Fig. 2 is a schematic view of a device for removing a foam layer from a substrate in accordance with an embodiment of the present invention, Figs. 3-10 is a schematic series of figures showing the removal of a plaster-bearing foam layer and a plaster layer arranged on the foam layer from a substrate in the form of a plastered, single-stage sealed wall in accordance with an embodiment of the present invention, and Figs. 11-14 are a schematic series of figures showing the removal of a plaster-bearing foam layer and a plaster layer arranged on the foam layer from a plastered, single-stage sealed wall in accordance with an alternative embodiment of the present invention.
    THE INVENTION With reference to Fig. 1, a plastered, single-stage sealed wall 10 is schematically illustrated comprising a plaster layer 11, a plaster-bearing foam layer 12, a substrate in the form of a building board 13, insulation 14, joists 15, possibly a sealing layer 16 and an interior board 17. The wall 10 comprises, for example, additional layers, such as fabric, glue, windboard, vapor barrier and the like in a conventional manner. The plaster layer 11 is, for example, arranged directly on the foam layer 12 or via a fabric, such as a fiberglass fabric, which is attached to the foam sheet by means of adhesive in a conventional manner. The cellular plastic layer 12 is, for example, arranged directly on the building board 13. The building board 13 is, for example, a wind protection board, gypsum board, chipboard, fibreboard, veneer board, mineral fiber board or the like. The building board 13 is, for example, arranged on joists 15 10 15 20 25 30 8 via windboard or equivalent. The rules 15 form a conventional set of wooden or metal rules. Thus, the wall 10 is, for example, a plastered, single-stage sealed rule wall. Alternatively, the wall 10 comprises a stone wall, where the foam layer 12 and the plaster layer 11 are arranged on the stone wall, the stone wall forming the substrate for receiving the foam layer 12.
    Referring to Fig. 2, there is shown a device 18 for removing the foam layer 12 from the building board 13. According to an embodiment of the invention, the device 18 is designed to remove only the foam layer 12. According to an alternative embodiment of the invention, the device 18 is designed to remove the plaster-bearing foam layer 12 and the plaster layer 11 arranged on the foam layer 12 from the substrate of the wall 10. The device 10 is, for example, designed for use in dismantling a wall 10.
    The device 18 comprises a body 19, a first arm 20 projecting from the body 19, a second arm 21 arranged at a distance from the first arm 20 and a heating wire 22 extending from the first arm 20 to the second arm 21. For example, the arms 20, 21 substantially perpendicularly and parallel from the same side of the body 19, a first end of the respective arm 20, 21 being connected to the body 19 and a second end of the respective arm 20, 21 being connected to the heating wire 22. The heating wire 22 is attached, for example. at the far end of the respective arm 20, 21. The heating wire 22 is arranged by means of the arms 20, 21 at a distance from the body 19, forming a space 23 therebetween for receiving the foam layer 12.
    Thus, the heating wire 22 is arranged at a distance from the body 19 which corresponds to or is greater than a thickness of the foam layer 12. Alternatively, the heating wire 22 is arranged by means of the arms 20, 21 at a distance from the body 19 so that the space 23 is designed to receive the foam layer 12 and the plaster layer 11 arranged thereon. Thus, the heating wire 22 is arranged at a distance from the body 19 which corresponds to or is greater than a total thickness of the foam layer 12 and the plaster layer 11, which is described in more detail below.
    For example, the device 18 is provided with or connected to a transformer which, for example, generates a voltage of 8-24 volts depending on the length and thickness of the heating trees 22. The body 19, for example, connects the constituent components. The body 19 is, for example, of an insulating material and has a length and thickness which is dimensioned according to the material to be worked in. On the body 19 is a junction box 24 which connects the transformer to the heating trees 22 via a switch 25. The switch 25 is, for example, spring-loaded and can for example be activated with the thumb or forefinger. The device 18 is, for example, connected to or connectable to the transformer via a contact. 26. Alternatively, the device 18 is the battery drive.
    According to the embodiment shown, the device 18 comprises handles 27, the device 18 being designed as a hand tool for being poured by a person and operated manually. Alternatively, the device 18 is arranged in a stand or the like with moving parts for automatic or manual operation of the device 18.
    The transformer conducts current via the switch 25 on the body 19 to the arms 20, 21. The arms 20, 21, or at least the other arm 21, are for example made with a width of 1-20 mm, preferably, 2-10 mm, preferably 3-5 mm and for example about 4 mm. The arms 20, 21 are further designed with a rigidity so that they can keep the heating trees 22 stretched between them. The arms 20,21 are, for example, hollow and tapered in the direction of their outer other end. One end of the heating trees 22 is, for example, attached to the upper part of the body 19 via a clamping screw. Heating trees 22 run inside the arms 20, 21 in a tube until it meets a ridge 28 when it comes out of the tube via a sliding surface or a needle bearing. For example, the voltage is transferred from the transformer to the heating trees 22 in the cam 28.
    At the other end of the heating trees 22 there is a tension spring 29 which is attached to the opposite side of the body 19. The spring 29 is designed to compensate for expansion of the heating trees 22 when it is heated and cooled down. The spring 29 is, for example, attached to the end of the body 19 on the upper edge of the body 19. On this side, the heating trees 22 continue as on the other side through the pipe out through the narrow ridge. Heating trees 22 are connected between the arms 20, 21 and are tensioned, for example, via a clamping screw on the other side. Referring to Figs. 3-10, there is schematically described a method of at least partially disassembling a wall 10 by removing the plaster layer 11 and the foam layer 12 from the substrate 13 of the wall 10 in accordance with an embodiment of the present invention. . In the embodiment shown, the wall 10 is a plastered, single-stage sealed rule wall, the base being a building board 13, such as a plasterboard or chipboard. Thus, the method is carried out, for example, for at least partial dismantling of a plastered single-stage sealed wall, such as during renovation as a result of moisture damage or moisture examination. Alternatively, the wall 10 is a concrete or stone wall provided with at least the foam layer 12 and the plaster layer 11, the substrate being concrete or stone. Alternatively, the wall 10 is another type of wall with a foam layer 12 arranged on a substrate. Alternatively, the wall 10 is a wall with a foam-bearing layer 12 arranged on a substrate and plaster-bearing.
    In principle, the method is based on peeling off the cellular plastic layer 12 of the house façade by means of the device 18. To get to the bottom of the building board 13, to which the cellular plastic layer 12 is connected, the desired depth is traced with one or more slot machines with a blade, such as a diamond blade , which penetrates the plaster layer 11, the reinforcement of the plaster and the foam layer 12. The grooving machine is designed, for example, to produce grooves by sawing or milling. For example, the track machine is made in the form of a circular saw or other type of saw. The track machine is, for example, connected to a vacuum cleaner with filters that do not spread mold and hazardous substances further.
    According to the embodiment shown, initially a portion of the foam layer 12 and the plaster layer 11 are initially formed to form a recess or a first groove 30 in the wall 10. For example, a portion of the foam layer 12 and the plaster layer 11 are initially removed in a knot corner of the wall 10, so as shown in Fig. 3. This is achieved, for example, by arranging the first groove 30 in the wall 10 or the facade by means of the grooving machine. The first groove 30 is arranged, for example, from an upper portion of the wall 10 to a lower portion of the wall and runs, for example, substantially vertically. Suitably, a further groove is arranged by means of the grouting machine in a corresponding manner on the other side of the corner, which is not shown in the figure, after which the corner can be broken off and removed, cut off by means of a thermal knife with a heating tree, say 10 15 20 25 30 11. a saw or the like. The thermal knife is, for example, a conventional heating knife with a knife blade that can be heated and can, for example, be used when the device 18 cannot be accessed in accordance with the invention. Alternatively, the first groove 30 is not arranged at a knot corner but, for example, at any location on the wall 10. Alternatively, a portion of the foam layer 12 and the plaster layer 11 along a portion of the wall 10 at any location are removed to form the first groove 30.
    In the same way as the first track 30, a second track 31 is arranged at a distance from the first track 30, as shown in Fig. 4. For example, the second track is arranged by means of the track machine. For example, the distance between the first and second grooves (30, 31) is 50-1500 mm, 300-1200 mm, 500-1000 mm and, for example, about 700 mm. The second groove 31 is, for example, arranged substantially parallel to the first groove 30. Alternatively, the first and second grooves 30, 31 are arranged substantially horizontally along at least a portion of the wall 10. For example, further grooves are also arranged in the same way as the first and second grooves. the track 30, 31, a third track 32 being arranged at a distance from the second track 31 and a fourth track 33 being arranged at a distance from the third track 32, as shown in Fig. 5.
    The grooves 30, 31 are applied, for example, substantially vertically, horizontally or both vertically and horizontally to form a grid pattern.
    After providing at least the second groove 31, the plaster layer 11 is removed between the first and second grooves 30, 31, as shown in Fig. 5.
    For example, the plaster layer 11 is pulled off manually after the grooves 30-33 have been provided through the plaster layer 11 and the foam layer 12. For example, the plaster layer 11 is removed in sections substantially corresponding to a surface between the grooves 30-31 for easy and environmentally friendly handling. Fig. 5 shows the removal of a first section 34 plaster layer 11. In Fig. 6, a second and third section plaster layer 11 have also been removed.
    It happens that the foam layer 12 is connected to the building board 13 by means of fastening devices 35 in the form of screws or the like, as shown in Fig. 5. The fastening devices 35 are usually exposed when removing the plaster layer 11. In case fastening devices 35 are arranged through the foam layer 12 10 15 20 25 30 12 these are removed. For example, the fasteners 35 are removed by means of a suitable tool. The fasteners 35 are removed in Fig. 6.
    After making the second groove 31, after removing the plaster layer 11 or at least a section 34 thereof and after removing any fastening devices 35, the heating wire 22 is inserted into an inner portion of the foam layer 12, the device 18 being passed along the grooves 30, 31, so as shown in Fig. 7 and Fig. 8. For example, the device 18 is attached to one end of the grooves 30, 31, such as an upper or lower end of the wall 10.
    The heating wire 22 is inserted into a portion of the foam layer 12 at the building board 13, so that the heating wire 22 extends between the grooves 30, 31. Optionally, additional grooves are arranged in the wall extending between the first and second grooves 30, 31, through which the heating wire 22 can be inserted. to a portion of the foam layer 12 at the building board 13. The device 18 is then passed along the wall 10, as shown by the arrow A in Fig. 7 and Fig. 8, so that the heating wire 22 cuts through an inner portion of the foam layer 12 at the building board. 13 at the same time as the second arm 21 of the device 18 is inserted into and along the second groove 31. Thus, at least the second groove 31 is arranged with a width for receiving the second arm 21 of the device 18 with its cam 28, so that the second arm 21 can be inserted into the second groove 31 and passed along it. Thus, the blade of the track machine is made with a width which corresponds to or is greater than at least the width of the other arm 21. The blade is so wide that the cam 28 of the device 18 comes down into the groove 31. The track machine where the blade is mounted has, for example, a construction so that the desired depth can be set according to the thickness of foam layer 12 and plaster layer 11. There is also a connection for vacuum cleaner so that abrasive dust does not escape into the air.
    As can be seen in particular from Fig. 8, the arms 20, 21 are made with a length for the heating wire 22 to reach substantially to the building board 13 and to form the space 23 between the body 19 and the heating wire 22 through which the foam layer 12 can pass. Thus, the length of the arms 20, 21 is substantially equal to or greater than a thickness of the foam layer 12, whereby a distance between the heating wire 22 and the body 19, i.e. a depth of the space 23, is greater than said thickness. For example, the length of the arms 20, 21 10 15 20 25 30 is adjustable, a depth of the space 23 being adjustable to adapt to the actual thickness of the foam layer 12.
    The device 18 is passed along the wall 10 and along the grooves 30, 31, for example from a first end of the grooves 30, 31 to a second end of the grooves 30, 31, the heating wire 22 cutting through the foam layer 12 until a first portion or a first section 37 of the foam layer 12 can be removed, as shown in Fig. 9. Thereafter, the first section 37 is removed from the substrate or building board 13. Thereafter, the procedure is repeated so that further portions or sections of the wall 10 facade are removed, as shown in Fig. 10. For example, when the third groove 32 is arranged at a distance from the second groove 31, then the heating wire 22 of the device 18, for example at one end of the grooves 31, 32, is inserted into a portion of the foam layer 12 at the building board 13, wherein the device 18 is moved along the wall 10 at the same time as the second arm 21 of the device 18 is inserted into the third groove 32 and the heating wire 22 cuts through the foam layer 12. In this way a second section 38 of the foam layer 12 is cut away from b ygg disc 13 and removed.
    Referring to Figs. 11-14, an alternative method of removing the foam layer 12 is schematically described in which the plaster-bearing foam layer 12 and the plaster layer 11 provided on the foam layer 12 are simultaneously removed from a substrate of a wall 10. The method comprises the steps of initially arranging grooves. 30, 31 in a corresponding manner as described with reference to Fig. 3 and Fig. 4, wherein a portion of the foam layer 12 and the plaster layer 11 are removed to form recesses in the form of the first groove 30 and the second groove 31 in the wall 10. Additional grooves may be provided in the wall.
    After making the second groove 31, the heating wire 22 is inserted behind the plaster layer 11 and into an inner portion of the foam layer 12, whereby the device 18 can be passed along the grooves 30, 31 in a corresponding manner as described above. The heating wire 22 is inserted into a portion of the foam layer 12 at the building board 13, so that the heating wire extends between the grooves 30, 31. The device 18 is then passed along the wall 10, as shown by the arrow A in Fig. 11 and Fig. 12, so that the heating wire 22 cuts through an inner portion of the foam layer 12 at the building board 13 at the same time as the second arm 10 of the device 18 is inserted into and along the second groove 31. The groove machine for receiving the grooves 30, 31 has for example, a construction so that the desired depth can be set according to the thickness of the foam layer 12 and the plaster layer 11.
    As can be seen in particular from Fig. 11, the arms 20, 21 are made with a length for the heating wire 22 to reach substantially to the building board 13 and to form the space 23 between the body 19 and the heating wire 22 which the foam plastic layer 12 and the plaster layer 11 can pass through. . Thus, the length of the arms 20, 21 is greater than a total thickness of the foam layer 12 and the plaster layer 11, a distance between the heating wire 22 and the body 19, i.e. a depth of the space 23, is greater than said thickness. For example, the length of the arms 20, 21 is adjustable, a depth of the space 23 being adjustable to adapt to the actual thickness of the foam plastic layer 12 and plaster layer 11.
    The device 18 is passed along the wall 10 and along the grooves 30, 31, for example from a first end of the grooves 30, 31 to a second end of the grooves 30, 31, the heating wire 22 cutting through the foam layer 12 until a first section or a first portion 39 of the facade of the wall 10, i.e. the cut-off portion of the foam layer 12 and the plaster layer 11, can be removed, as shown in Fig. 13. Then the first portion 39 is removed from the substrate or the building board 13. Then the procedure is repeated, so that further portions or sections of the wall 10 are removed, as shown Fig. 14. For example, when the third groove 32 is arranged at a distance from the second groove 31, after which the heating wire 22 of the device 18, for example at one end of the grooves 31, 32, is inserted into a portion of the foam layer 12 at the building board 13 , the device 18 being moved along the wall 10 at the same time as the second arm 21 of the device 18 is inserted into the third groove 32 and the heating wire 22 cuts through the foam layer 12. In this way a second section or a second portion 40 of the foam layer 12 and the plaster layer arranged thereon are cut. 11 removed from the substrate and removed.
    In the event that access is not made with the device 18, such as for example around windows 41, doors and the like, for example the thermal knife as above is used to remove parts of the façade. In case the device 18 cannot be accessed, for example chemicals are used. Chemicals, such as acetone, methyl ethyl ketone (MEK) or the like that dissolve the foam, are used, for example, to remove foam residues when needed and in those places where chemical use is judged to be the best alternative. The chemicals are applied behind the plaster layer and dissolve the cellular plastic.
    The removal of the foam layer 12 is optionally followed by sanding to remove any residual adhesive and any residue of the foam layer 12. The removal of the foam layer 12 and any subsequent sanding exposes fasteners 42 connecting the substrate 13 to the bolts 15.
    The fasteners 42 are, for example, conventional screws or nails for fastening the base 13 in the form of plasterboard, chipboard or the like to a set of bars 15. In cases where it is deemed appropriate to remove the base 13 or parts thereof, such as post-moisture measurements, inspection or the like, the fasteners 42 are removed, whereby the substrate 13 can be dismantled and disposed of. The fasteners 42 are removed, for example, by means of a machine for mechanical processing, such as a milling machine or a saw. For example, the milling machine is designed to mill through the substrate 13 or the disc, ie. usually about 12-13 mm.
