  By the way, in floor heating construction, when a flooring is pasted with a hot melt adhesive, a hot water mat that is an air conditioning function base material has a metal heated member disposed on the front side via a metal sheet for heat diffusion, On the other hand, in the base material for thickness adjustment, a metal heated member is directly disposed on the front side of a non-metallic substrate such as a plywood. As a result, when each metal heated member is heated by electromagnetic induction with the same output from above the flooring, the magnitude of the induction current generated in the metal heated member of the hot water mat and the metal of the thickness adjustment base material are actually Unlike the magnitude of the induced current generated in the member to be heated, there is a large difference in the heat generation temperature.

  Therefore, to apply to two different base materials, in order to securely bond the flooring, when operating the electromagnetic induction heating device, operate the irradiation time adjustment timer provided in the power supply unit, It is necessary to adjust the output such as adjusting the heating time. Therefore, there is a situation that work is complicated and inefficient.

Can be glued to the finished state. Moreover, since the flooring (4) can be pressed only by moving the gantry (6), the curing operation of the flooring (4) to be processed next can be performed while the hot melt adhesive is cured. Workability can be further improved.

  As shown in FIG. 3, the base structure of the present invention has two types of base materials (2) for adjusting the thickness of the hot water mat (1), which is a flat base material for air-conditioning and heating function, and a flat plate for adjusting the thickness (2). It consists of a base material. That is, in the construction of floor heating in a living room or the like, a warm water mat (1) is laid in the center of the room, and a base material (2) for adjusting the thickness for laying the flooring (4) to the corner of the room is provided. It is laid around the hot water mat (1). The hot water mat (1) is manufactured to a predetermined size on site according to the installation location such as a living room, or one or a plurality of ones having a standard size is used in combination. Moreover, the base material (2) for thickness adjustment is used by carrying out on-site processing suitably according to an installation place. FIG. 3 shows an example in which one hot water mat (1) is arranged in the center of the room.

  As shown in FIG. 1, the hot water mat (1) is diffused over substantially the entire front side of the foamed resin molded body (11), which is a non-metallic base material in which a water passage pipe (13) as a heat medium pipe is embedded. The metal sheet (14) is disposed, and the metal heated member (3) is disposed further on the front side of the heat diffusion metal sheet.

  Specifically, in the hot water mat (1), flat foam resin moldings (11) and small joists (12) are alternately arranged in parallel at regular intervals, and water is passed through the foam resin molding (11). The pipe (13) is embedded, and a metal sheet for heat diffusion (14) such as aluminum foil is disposed on the front side of the foamed resin molded body (11). Further, the front side of the metal sheet for heat diffusion (14) The metal heated member (3) is disposed along the small joist (12). Usually, the warm water mat (1) has a width of about 600 to 4000 mm, a length of about 600 to 4000 mm, and a thickness of about 6 to 24 mm.

  Examples of the foamed resin molding (11) include rigid polyurethane foam, rigid polyethylene foam, rigid polypropylene foam, polystyrene foam, rigid polyvinyl chloride foam, polymethyl methacrylate foam, polycarbonate foam, and polyphenylene oxide foam. And foams of a mixture of polystyrene and polyethylene. Among these, hard polypropylene foam, hard polyurethane foam, polystyrene foam and the like are suitable.

  In the hot water mat (1), each foamed resin molded body (11) is disposed between the small joists (12) parallel to the width direction of the hot water mat, so that the planar shape is formed into an elongated rectangle. (See FIG. 3). The length and thickness of the foamed resin molded body (11) are respectively designed according to the width and thickness of the hot water mat (1), and the width of the foamed resin molded body (11) is about 240 to 600 mm. The Moreover, the nonwoven fabric etc. may be affixed on the lower surface of a foamed resin molding (11) as a sound insulation material. Furthermore, in order to facilitate the handling at the time of construction, the foamed resin molded body (11) may be provided with a cut, and although not shown, it is divided to constitute the hot water mat (1) in a folded structure. It may be.

  The small joist (12) is a small member for supporting an overload including the flooring (4). For example, wood such as cedar, cherry, cypress, lauan and plywood, or a metal heated member (3 ) Is a resin molded body that can withstand the heat generation. The length and thickness of the small joists (12) are each designed in accordance with the above-described width and thickness of the hot water mat (1), but usually the width is about 30 to 60 mm. In addition, the above foamed resin moldings (11) and small joists (12) are integrated by sticking a metal sheet for heat diffusion (14) on these surfaces.

  The water flow pipe (13) usually uses a groove formed on the surface of the foamed resin molded body (11), and is brought into contact with the metal sheet for heat diffusion (14) to the foamed resin molded body (11). Buried. Examples of the water flow pipe (13) include a crosslinked polyethylene pipe, a polybutene pipe, a polypropylene pipe, a copper pipe, and a resin pipe having a metal wire embedded in its peripheral surface. Polybutene tubes are used. The water pipe (13) has an outer diameter of about 6 to 15 mm and an inner diameter of about 4 to 10 mm.

  The metal sheet for heat diffusion (14) is a heat radiating sheet that conveys the heat of hot water from the water flow pipe (13) to the flooring (4) side. Affixed to the surface. As the metal sheet for heat diffusion (14), a flexible film or sheet having a thickness of about 10 μm to 2 mm and excellent in thermal conductivity, such as aluminum foil, tin foil, copper foil, stainless steel foil, etc. A metal foil, a metal woven fabric or nonwoven fabric, a resin film or a resin sheet, or a laminated sheet combining these is used. Usually, aluminum foil is used from the viewpoint of ease of production and cost.

  The metal sheet for heat diffusion (14) is usually attached to the surface of the foamed resin molded body (11) and the small joist (12) using an adhesive or an adhesive film. Such adhesives or adhesive films include ethylene / acrylic acid copolymers, ethylene / vinyl acetate copolymers, ethylene / glycidyl acrylate copolymers, ethylene / maleic anhydride copolymers, polyethylene acrylic acid graft copolymers. Examples thereof include thermoplastic resins such as a polymer and a maleic anhydride graft copolymer of polyethylene.

  The metal heated member (3) is a belt-shaped, for example, steel sheet or thin plate designed to have a width of about 20 to 60 mm and a thickness of about 0.1 to 3 mm. When the flooring (4) is disposed, the metal sheet for heat diffusion (14) is positioned so as to be along the width direction of the flooring, specifically, on the upper surface side of the small joist (12). Attached to the front side of the film with an adhesive. The arrangement pitch of the metal heated members (3) is, for example, 150 to 650 mm. As a metal which comprises metal to-be-heated member (3), metals, such as aluminum alloy, cobalt, nickel other than iron containing said steel, are mentioned. Considering the amount of heat generated by electromagnetic induction, a ferromagnetic material such as iron is preferable.

  The hot melt adhesive is affixed to the front side of the metal heated member (3). As such a hot melt adhesive, various known thermoplastic resins such as polyethylene, polyisobutylene, polyamide, vinyl acetate-ethylene copolymer are generally used. The metal heated member (3) may be attached in advance to the front side of the hot water mat (1) when the hot water mat is manufactured in a factory, or may be attached at a construction site. Moreover, a hot melt adhesive may also be affixed to the metal heated member (3) at the construction site.

  On the other hand, as shown in FIG. 1, the base material for thickness adjustment (2) has a metal heated member (3) similar to the above disposed on the front side of a flat non-metallic substrate (21). Composed. The thickness adjusting base material (2) is used after being processed to an appropriate size, but usually the planar shape is designed to be a rectangle having a width of about 150 to 1000 mm and a length of about 900 to 2000 mm. . Further, the thickness is set to about 6 to 24 mm in order to match the hot water mat (1).

  As the non-metallic base material (21), structural plywood such as veneer or particle board is usually used. Moreover, as a nonmetallic base material (21), the foamed resin board similar to the foamed resin molding (11) of a warm water mat (1) can also be used. For example, the thickness adjusting base material (2) shown in FIG. 2 (a) is a base material using a wood board (21a) as a non-metallic base material, and the thickness adjusting base material shown in FIG. 2 (b) is used. A base material (2) is a base material which uses the foamed resin board (21b) as a nonmetallic base material in order to improve heat insulation performance.

  In addition, as shown in FIG. 2B, when the foamed resin plate (21b) is used as the base material in the thickness adjusting base material (2), the strength against the mounting load is increased and the metal heated member ( In order to prevent the foamed resin plate from being damaged by the heat generated in 3), a small joist (21c) is arranged. The configuration and arrangement of the small joist (21c) is substantially the same as the small joist (12) of the hot water mat (1). Furthermore, as shown in FIG.2 (c), when using a foamed resin board (21b) as a base material, resin-made small joists (21d) which have heat insulation as well as heat resistance may be arrange | positioned. When the resin small joists (21d) are arranged, the outflow of heat to the back side (under the floor) can be reduced.

  The metal heated member (3) disposed on the front side of the thickness adjusting base material (2) is configured in the same manner as in the case of the hot water mat (1) described above. And the hot-melt-adhesive similar to the case of a warm water mat (1) is affixed on the front side of a metal to-be-heated member (3). The metal heated member (3) may be attached simultaneously with the application of the flooring (4) at the construction site by applying a hot melt adhesive on both surfaces thereof.

  By the way, as described above, in the thickness adjusting base material (2), when the metal heated member (3) is directly disposed on the surface of the non-metallic base material (21), the metal material by electromagnetic induction heating is used. The amount of heat generated by the heated member (3) is different from the amount of heat generated by the metal heated member (3) of the hot water mat (1). That is, the metal heated member (3) disposed directly on the surface of the non-metallic base (21) is a metal sheet for heat diffusion on the surface of the non-metallic base (3) like the hot water mat (1). Compared with the metallic member to be heated (3) disposed on (14), the induced current easily flows by irradiation of the magnetic lines of force, in other words, the resistance value is small and the heat generation amount is small.

  Therefore, in the present invention, as shown in FIGS. 1 and 2, in order to make the resistance values of the metal heated members (3) of the hot water mat (1) and the thickness adjusting base material (2) uniform, The base material for adjusting the thickness (2) includes a metal sheet (24) for adjusting the resistance value disposed on the front side of the non-metallic base material (21) (wood board (21a) or foamed resin board (21b)) and The metal heated member (3) is arranged on the front side of the resistance value adjusting metal sheet. That is, said metal to-be-heated member (3) is arrange | positioned through the resistance-value adjustment metal sheet | seat (24) in the front side of a nonmetallic base material (21). Thereby, the flooring (4) can be applied efficiently without switching the output of the electromagnetic induction heating device (5).

  The resistance-adjusting metal sheet (24) has a thickness of about 10 μm to 2 mm and has excellent thermal conductivity, like the heat diffusion metal sheet (14) of the hot water mat (1). Film or sheet, for example, metal foil such as aluminum foil, tin foil, copper foil, stainless steel foil, metal woven or non-woven fabric, or a laminated sheet combining these, etc. Aluminum foil is used from the standpoint of thickness and cost. The metal sheet for resistance value adjustment (24) described above is for making the heat generation temperature of each metal heated member (3) as uniform as possible with the hot water mat (1) and the base material for thickness adjustment (2). Preferably, the hot water mat (1) is made of a metal material similar to the metal sheet for heat diffusion (14).

  Further, the magnitude of the induced current generated in the metal heated member (3) of the thickness adjusting base material (2) also differs depending on the size of the resistance adjusting metal sheet (24). It was confirmed that a remarkable effect was obtained when the resistance-adjusting metal sheet (24) protruded outward from the heated member (3). Therefore, the resistance-adjusting metal sheet (24) has a size of the induced current generated in the metal heating member (3) of the thickness adjusting base material (2), in other words, the thickness adjusting base material. In order to make the resistance value of the metal heated member (3) of the material (2) equal to the metal heated member (3) of the hot water mat (1), the metal cover of the thickness adjusting base material (2) It is formed in a strip shape having a width larger than the width of the heating member (3).

  The width of the metal sheet for resistance value adjustment (24) is 120% or more of the width of the metal heated member (3) of the base material for thickness adjustment (2), usually 120 to 500%, preferably It is set to 150 to 250%. The resistance value adjusting metal sheet (24), when viewed in plan, protrudes from both edges along the length direction of the metal heated member (3) on the front side, and the length of each protrusion Is set to 20% or more of the width of the metal heated member (3). The reason why the width of the resistance-value adjusting metal sheet (24) is defined as described above is as follows.

  That is, when the magnetic force lines are irradiated with the same output, the width of the resistance adjustment metal sheet (24) is 120% or more of the width of the metal heated member (3) and from both sides of the metal heated member (3). When the overhang length is 20% or more of the width of the metal heated member (3), the temperature is approximately 80% or more of the heating temperature of the metal heated member (3) of the hot water mat (1). The metal heated member (3) of the base material for thickness adjustment (2) can be heated up to 150 mm, and the width of the metal sheet for resistance value adjustment (24) is 150 of the width of the metal heated member (3). % And the protruding length from both sides of the metal heated member (3) is 30% or more of the width of the metal heated member (3), the metal heated member of the hot water mat (1) ( The metal heated member of the base material for thickness adjustment (2) up to a temperature substantially equivalent to the heating temperature of 3) 3) can be heated was confirmed.

  On the other hand, even if the width of the resistance-adjusting metal sheet (24) is 120% or more of the width of the metal heated member (3), the metal heated member (3) protrudes from one side. When the length is less than 20% of the width of the metal heated member (3), the heating temperature of the metal heated member (3) of the hot water mat (1) is only less than about 80% of the heating temperature. It was confirmed that the metal heated member (3) of the base material for thickness adjustment (2) could not be heated. In addition, the resistance-adjusting metal sheet (24) may be disposed on substantially the entire front surface of the non-metallic base material (21). However, from a practical viewpoint for reducing the material cost, the metallic sheet (24) is made of metal. It is set to 500% or less of the width of the member to be heated (3).

  In addition, in the thickness adjusting base material (2) as shown in FIGS. 2B and 2C using the foamed resin plate (21b), the resistance adjusting metal sheet (24) is as follows. As long as the above-described conditions are satisfied, the width may be set to the same width as the small joists (21c) and (21d), although not shown. When the resistance value adjusting metal sheet (24) is set to the above width, the metal sheet for constituting the resistance value adjusting metal sheet (24) is attached to the entire surface of the wooden board or the resin board. By cutting a wooden board or a resin board into a predetermined size, a small joist (21c) or (21d) to which a resistance value adjusting metal sheet (24) is attached can be immediately manufactured. Can increase productivity.

  In the construction of the flooring (4) using the base structure of the present invention as described above, as shown in FIG. 3, the hot water mat (1) laid on the floor assembly and the thickness adjusting base material (2) On the other hand, while arranging the flooring (4) so that the length direction of the metal heated member (3) and the length direction of the flooring (4) are orthogonal to each other, as shown in FIG. The heating coil device (52) of the electromagnetic induction heating device (5) is pressed against the portion corresponding to the metal heated member (3) on the surface of the metal, and the magnetic heated member (3) is induction heated by irradiating magnetic lines of force. To do.

  At that time, in the electromagnetic induction heating device (5), the heating operation is performed with the output set constant. The output of the electromagnetic induction heating device (5) required to heat each metal heated member (3) of the hot water mat (1) and the base material for thickness adjustment (2) to, for example, 160 ° C is Although it is determined by measuring in advance, it is generally about 2 to 7 W · h. Then, the flooring (4) is attached to the upper surfaces of the hot water mat (1) and the base material for thickness adjustment (2) by melting the hot melt adhesive on the surface by heating the metal heated member (3). wear.

  As described above, in the base structure of the present invention, the resistance adjustment metal sheet (24) as shown in FIGS. 1 and 2 is arranged on the front side of the thickness adjustment base material (2). When electromagnetic induction heating is performed at a constant output, each metal heated member (3) of two types of base materials, a hot water mat (1) and a thickness adjusting base material (2) laid around the hot water mat (1) Since induction currents of the same magnitude are generated and there is no difference in the heat generation temperature, the electromagnetic induction heating device (5) is used for both the hot water mat (1) and the base material for thickness adjustment (2). Efficient construction with constant output without adjusting output.

  Moreover, since there is no need to switch the output of the electromagnetic induction heating device (5) between the hot water mat (1) and the thickness adjusting base material (2), there is no possibility of erroneous operation of the electromagnetic induction heating device (5). Poor adhesion of the flooring (4) due to insufficient heating, that is, poor adhesion of the flooring (4) due to insufficient heating of the base material for thickness adjustment (2) to the metal heated member (3), or due to overheating of the member Without causing damage, that is, damage to the foamed resin molded body (11) or the water pipe (13) due to excessive heating of the hot water mat (1) to the metal heated member (3), the flooring ( 4) can be glued.

  The electromagnetic induction heating device (5) is used under the same conditions as when the flooring (4) is bonded to the hot water mat (1), and the flooring (4) is attached to the base material for thickness adjustment (2). The difference of the adhesion state by the difference in the structure regarding the metal sheet for resistance value adjustment (24) of the base material for thickness adjustment (2) was confirmed. The hot water mat (1) used for setting the conditions for electromagnetic induction heating is made of a metal for heat diffusion made of aluminum having a thickness of 0.1 mm on the entire front side of a 12 mm thick foamed resin molded body (11) made of a hard polypropylene foam. A sheet (14) is attached, and a steel metal heated member (3) having a width of 45 mm and a thickness of 0.25 mm is attached to the front side, and on the surface of the metal heated member (3), Polyamide was stuck as a hot melt adhesive with a thickness of 0.3 mm. Moreover, the flooring (4) used what was manufactured with the teak plywood of thickness 12mm. Then, as suitable conditions for attaching the flooring (4) to the hot water mat (1), the output of the electromagnetic induction heating device (5) was set to 4.2 W · h, and the irradiation time of the lines of magnetic force was set to 10 seconds.

Example 1:
As a thickness adjusting base material (2), a 0.1 mm thick aluminum resistance adjusting metal sheet (24) is arranged on the front side of a wooden board (plywood) (21a), and a hot water mat ( 1) the same metal heated member (3) (steel metal heated member having a width of 45 mm and a thickness of 0.25 mm), and a hot water mat on the surface of the metal heated member (3) The base material which stuck the hot-melt-adhesive similar to (1) was prepared. The resistance-adjusting metal sheet (24) has a width of 75 mm and a protrusion length from both edges of the metal heated member (3) in plan view of 15 mm (metal heated member ( Equivalent to 33% of the width of 3). And after attaching a flooring (4) to said base material for thickness adjustment (2) by electromagnetic induction heating, when this was peeled and the adhesion | attachment state was confirmed, on the whole surface of a metal heated member (3) As a result, it was confirmed that the hot melt adhesive was completely melted and had sufficient adhesive strength as well as the adhesive strength of the hot water mat (1) to the metal heated member (3).

Example 2:
A base material having the same configuration as in Example 1 was prepared as the base material for thickness adjustment (2), except that the width of the metal sheet for resistance value adjustment (24) was different. The resistance-adjusting metal sheet (24) has a width of 65 mm and a protruding length from both edges of the metal heated member (3) in plan view of 10 mm (metal heated member ( Equivalent to 22% of the width of 3). And after attaching a flooring (4) by electromagnetic induction heating similarly to Example 1, when this was peeled and the adhesion state was confirmed, it is equivalent to about 80% of the surface of a metal to-be-heated member (3). It was confirmed that the hot melt adhesive was completely melted and the adhesive strength was slightly lower than the adhesive strength of the hot water mat (1) to the metal heated member (3), but there was no practical problem.

Example 3:
A base material having the same configuration as in Example 1 was prepared as the base material for thickness adjustment (2), except that the width of the metal sheet for resistance value adjustment (24) was different. The resistance-adjusting metal sheet (24) was disposed in a state where the width was 45 mm, which was the same as that of the metal heated member (3), and overlapped with the metal heated member (3) when viewed in plan. And after attaching a flooring (4) by electromagnetic induction heating similarly to Example 1, when this was peeled and the adhesion state was confirmed, it is equivalent to about 65% of the surface of a metal to-be-heated member (3). The hot melt adhesive is completely melted, and the adhesive strength is lower than the adhesive strength of the hot water mat (1) to the metal heated member (3), depending on the width (adhesive area) of the metal heated member (3). Was confirmed to be usable.

Comparative Example 1:
As the base material for thickness adjustment (2), a metal heated member (3) similar to the hot water mat (1) is directly arranged on the front side of the wood board (plywood) (21a), and the metal heated member (3 The base material which stuck the hot-melt-adhesive similar to a warm water mat | matte (1) on the surface of) was prepared. And after attaching a flooring (4) by electromagnetic induction heating similarly to Example 1, when this was peeled and the adhesion state was confirmed, only the surface by the side of the metal to-be-heated member (3) side of a hot melt adhesive was used. Was partially melted, and it was confirmed that the adhesive strength was clearly lower than the state of adhesion of the hot water mat (1) to the metal heated member (3) and could not be put into practical use.
