On the other hand, an adhesive layer covered with a release sheet is provided on the back surface of the carpet or the like, and the release sheet is removed and attached at the time of use to eliminate the work of applying the adhesive or the like. However, even in that case, it is necessary to handle the carpet carefully so that the exposed adhesive layer does not adhere to other things until it is stuck in place. Also, it is not possible to improve the time when replacing the carpet.

Further, when the above carpet is laid without adhering to the floor surface, for example, when it is laid in a large place such as a hotel hall, it is difficult to cover the hall with one carpet. The carpets will be laid side by side. At that time, it may be necessary to lay the carpets according to the design of the carpet. In such a case, it is necessary to connect the carpets in a pre-patterned state before laying them, so apply an adhesive to the back surfaces of the edges of both carpets to be connected and attach an appropriate connecting sheet. Construction is required, and in this case as well, the same problems as when the flooring of the carpet is adhered will occur.

In view of the above, the present invention does not require an adhesive application work and can easily apply a non-metal sticking material such as carpet to an object such as a building or furniture by simple handling. It is an object of the present invention to provide an adhesive underlayment sheet that can connect pasting materials to each other and that can easily replace the pasting materials.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an underlay sheet 1 according to a first embodiment of the present invention, in which heat-melting adhesives (hot melt) adhesives 3, 3 have a predetermined thickness on both sides of an aluminum foil 2. (For example, 0.1 to 0.2 mm) is applied in a layered structure.

Next, an explanation will be given of a method of applying the carpet to the floor surface using the above-mentioned underlayment sheet 1. As shown in FIG. 1, the underlayment sheet 1 wound in a roll shape is cut into a predetermined size. Then, an underlay sheet 1 having a shape and a shape is obtained, which is laid on a floor 4 as shown in FIG. 3, and a carpet 5 is laid on it as shown in FIG. Slide it up and irradiate the underlay sheet 1 with electromagnetic waves in the state shown in FIG. This irradiation causes an induced current in the aluminum foil 2 of the underlayment sheet 1 to generate heat due to the electric resistance of the foil 2, and the heat melts the heat-melting adhesives 3 and 3 on both sides of the aluminum foil 2 and the floor surface 4 The underlay sheet 1 and the carpet 5 are adhered to the.

Therefore, if the above-mentioned underlay sheet 1 is used, the work of applying the adhesive to the floor surface 4 in advance can be eliminated, so that the carpet laying work is simple and the construction can be completed in a short time, and the periphery is soiled with the adhesive. Will disappear. Moreover, since the adhesives 3, 3 of the underlayment sheet 1 are solidified until they are irradiated with electromagnetic waves, they do not adhere even if they come into contact with other objects during handling, and therefore the handling is easy. In addition, the carpet 5 can be easily set at a predetermined position on the floor surface 4.

Further, in the carpet 5 attached using the above-mentioned underlay sheet 1, if the underlay sheet 1 is subsequently irradiated with electromagnetic waves again, the adhesives 3 are melted. The old carpet can be easily peeled off and the replacement work can be done easily.

Building materials that can be adhered by the above-mentioned underlay sheet 1 include carpet, cushion floor, peat tile (rubber), flooring, tile, board, board, etc., in particular of tile. In this case, the conventional cement priming work on the wall surface can be eliminated. Further, when the material of the floor surface and the wall surface to which these are attached is metal, electromagnetic waves are absorbed by the metal and interfere with heat generation due to the induced conductive flow generated in the aluminum foil 2, but other materials are used. If applicable, it can be applied to a wide range of materials such as mortar, concrete blocks, wood and stone.

By the way, as shown in FIGS. 6 and 7, the electromagnetic wave irradiation device 6 for irradiating the above-mentioned underlay sheet 1 with an electromagnetic wave has a grip 7 for an operator to hold, and an electromagnetic wave generation coil 8 on the inner bottom portion. When the electromagnetic wave irradiation device 6 is placed on the underlayment sheet 1 from a state in which the main switch 9 provided in the grip 7 is turned on, the coil 8 is energized to generate an electromagnetic wave, and the device The operating state of 6 is displayed by the light emission of the light emitting diode 10.

A power supply box 12 shown in FIG. 6 is connected to the electromagnetic wave irradiation device 6 by a connection cable 11, and a commercial power supply voltage is boosted by a transformer (not shown) provided inside the power supply box 12. Then, the electromagnetic wave irradiation device 6 is supplied with power. Further, the power supply box 12 can be moved by the casters 13 so as to follow the movement of the electromagnetic wave irradiation device 6, and a power supply switch 14, a voltage adjusting volume 15, and a light emitting diode 16 for displaying an operating state are provided.

FIG. 8 shows an underlay sheet 101 according to the second embodiment, which is used when, for example, materials such as a carpet are joined together. In other words, when laying carpets without gluing, if the place to be laid is a large place such as a hotel hall, it is difficult to cover the halls with one carpet, and multiple carpets can be laid. It will be laid against each other. In that case, when it is necessary to match the patterns between the carpets, the carpets must be connected to each other in a patterned state before being laid.

Therefore, the underlay sheet 101 is a strip-shaped sheet having a predetermined connection width D in which the heat-melting adhesive 3 is coated only on one surface of the aluminum foil 2. If the underlay sheet 101 is used, the carpets 5A and 5B to be connected are butt-lapped on top of each other in a pattern-matched state on the sheet 101, and electromagnetic waves are irradiated by the electromagnetic wave irradiation device 6 described above to generate an adhesive. Since the carpets 5A and 5B can be connected by melting No. 3, the carpet connection can be made by connecting a plurality of carpets in this way to form one piece and then laying it in the above space. Eliminates the need for adhesive application work. Therefore, the carpet laying work can be easily performed, and the surrounding area is not soiled with the adhesive.

By the way, in the underlay sheet 1 based on the aluminum foil 2 shown in FIG. 2, since the aluminum foil 2 is thin, wrinkles easily form on the aluminum foil 2 during handling of the sheet 1, and the underlay sheet is It may be difficult to lay No. 1 clean on the floor. On the other hand, as shown in FIG. 9, by laminating aluminum on the resin film 17 by a method such as vapor deposition, and coating an adhesive on both sides of the laminate of the resin film 17 and the aluminum foil 2. It is possible to avoid the above wrinkles. According to this underlay sheet 201, in addition to the prevention of wrinkles, the resin film 22 functions as a waterproof film, so that the waterproof function can be obtained at the same time by simply attaching the above, without separately carrying out waterproof construction. There is. This is also the case when a resin film is provided on the connection underlay sheet 101 of FIG.

In the above-mentioned embodiment, the carpet was explained as an example of the sticking material. However, in addition to sticking the building material such as this carpet, the adhesive underlayment sheet 1, 101, 201 can be widely applied to the adhesion of non-metal sticking materials other than the building material.

For example, as shown in FIG. 10, it can be used for adhering furniture materials, such as when adhering a beautiful plywood 18 to the surface of a desk 17. Artificial turf is laid in the so-called open-air practice range of golf. In that case, artificial turf is adhered to the rubber as the base material with an adhesive, but this adhesive is a thinner system that is harmful to humans, so this adhering work must be limited in working time. Not only that, the work efficiency was poor, and when replacing the artificial turf, it had to be discarded together with the rubber of the base material. However, by using the adhesive underlayment sheet of the present invention, it is possible to eliminate the limitation of the above-mentioned working time, and at the time of replacing artificial turf, the old artificial turf can be peeled off from the base material. There is an advantage that you can use it as it is and attach new artificial grass on it. As another example, it can be used for attaching the insole of the shoe to the shoe, attaching a plastic board for display to the base material, or joining the plastic board.

[Effect of device]

 As is apparent from the above description, according to the first aspect of the present invention, from the state in which the underlay sheet is laid on the surface of the object and the non-metal sticking material such as carpet is laid on it, When the underlay sheet is irradiated with an electromagnetic wave, an induced current flows in the metal foil of the underlay sheet by the electromagnetic wave, heat is generated due to the electric resistance of the metal foil, and the heat-meltable adhesive layers on both sides of the metal foil are melted and the above-mentioned pasting is performed. The working material will be adhered to the object.

According to the second aspect of the invention, the adhesive layer is melted by irradiating electromagnetic waves with both edges of the material for application such as carpet to be connected to each other on the adhesive coating side of the underlay sheet. The two materials for attachment will be connected.

[0028] Therefore, it is not necessary to apply an adhesive in advance to an object such as a floor surface or a material to be attached such as a carpet to be connected, and it is possible to apply the adhesive in a short time without contaminating the surrounding area, or to perform connection work. You can Moreover, since the adhesive of the underlay sheet is solidified until it is irradiated with electromagnetic waves, the underlay sheet can be easily handled, and the underlay sheet, carpet, etc. can be easily set at a predetermined position.

Further, the adhesive material adhered by the underlay sheet of the present invention can be easily peeled off because the adhesive melts when irradiated again with electromagnetic waves, and the replacement process becomes easy.

In addition, according to the third invention, the resin film reinforces the metal foil to prevent the underlay sheet from wrinkling, so that the underlay sheet can be laid cleanly on the object surface, and Since the resin film acts as a waterproof film, a waterproof type attachment structure or connection structure can be obtained without any special work.
