Description

  The present invention relates to a floor structure that can be heated. More specifically, the present invention relates to a floor structure that can be heated when applied to a newly built or existing building (house).

  Conventionally, various floor heating technologies have been proposed and put into practical use. As an example of conventional floor heating technology, a molded body made of synthetic foam resin or a wooden plate is used as a base material layer, and a heat transfer pipe is embedded in an embedded groove carved on one surface of the base material layer. In addition, there is a heat radiating plate such as a heating panel having a structure in which the surface of the base material layer in which the heat medium pipe is embedded is covered with a flexible thin plate such as an aluminum foil.

  This heat sink is mainly used when laying in a new structure such as a house. The heat sink is adopted in the newly built building because the owner has a floor structure that can be heated from the beginning of the building, instead of the normal floor surface, in consideration of the possibility of future renovation and moving. For example, when a building is desired. In contrast, rather than dismantling the existing floor surface and building a new floor structure that can be heated, the owner of the building leaves the existing floor surface and creates a floor structure that can be heated on the floor surface. If it is considered more reasonable to add a heat sink, a heat sink may be employed in a building that already exists.

  The above-mentioned heat sink is actually used with a covering material such as a flooring plate, tatami mat, or carpet. Of these, when using a soft carpet or wood floor finishing material on the heat sink, for example, the generation of sound during walking due to a decrease in the function of the adhesive or the heat transfer tube felt from above the carpet The sensation of foreign objects is a problem.

For the purpose of solving such a problem, a soft floor heating mat in which a thermoplastic sheet is interposed between each layer of a structure in which a nonwoven fabric layer is provided between the aluminum foil on the surface of the heat sink and the carpet and the adhesive strength is increased. A manufacturing method is proposed in Patent Document 1.

Main components of the floor structure unit that can be heated The main components in the floor structure unit that can be heated are the base material layer 10, the metal foil 20, the nonwoven fabrics 30, 31, the resin sheet 40, and the cover material 80. is there. Each of these main components will be described in detail with reference to FIG. 6 showing the floor structure unit 600 according to the sixth embodiment having all of such main components.

(1) Base material layer (a) Material of base material layer In the floor structure unit 600 which can be heated of this invention, the base material layer 10 is the heat-medium pipe | tube 12 embed | buried in the embedding groove | channel 11 carved on one surface. It fulfills the function of supporting. The base material layer 10 is preferably adjusted with a material having relatively high rigidity and heat resistance so that this function can be achieved. Examples of materials to be adjusted include wood, plywood, and synthetic resin. Of these, synthetic resins are preferred. Examples of suitable synthetic resins include polyamide resins such as polyamide 6, polyamide 6 · 6, polyamideimide, polyolefin resins such as polyethylene, polypropylene, ethylene-propylene copolymer, polystyrene, polyethylene terephthalate, polybutylene terephthalate, etc. Polyester resins, polyvinyl chloride, polyurethane and the like can be mentioned, and from the viewpoint of heat insulation, light weight, etc., a foamed synthetic resin prepared from these synthetic resins is particularly preferable. As the base material layer 10 of the floor structure unit 600 that can be heated according to the present invention, the expansion ratio in the case of using the adjusted foamed synthetic resin is usually preferably about 5 to 50 times. If the expansion ratio is less than 5 times, both the heat insulating property and the light weight of the base material layer 10 are inferior, so that it is not suitable.

(B) Shape of the base material layer In the floor structure unit 600 that can be heated according to the present invention, the width and the planar shape of the base material layer 10 are not particularly limited, but the area of the base material layer 10 is not limited in the case of packing, transportation, etc. It is preferable that the floor structure unit 600 is relatively small so as not to be bulky. When the floor structure unit 600 that can be heated according to the present invention is constructed, it is preferable that a plurality of floor structure units 600 be easily connected.

  In addition, the thickness of the base material layer 10 is appropriately determined in consideration of the density and rigidity of the material used for the base material layer 10, but if it is too thick, it becomes bulky and heavy during packaging, transportation, etc. It is preferable to make the heat medium pipe 12 as thin as possible so that the heat medium pipe 12 can be supported. On the other hand, if it is too thin, it is necessary to make the heat medium tube thinner, so that the amount of heat medium flowing is limited and the heat insulation property is not good, which is not preferable. From these viewpoints, the thickness of the base material layer 10 is preferably about 5 to 50 mm.

(C) Embedded Groove In the floor structure unit 600 that can be heated according to the present invention, the base material layer 10 is provided with an embedded groove 11 in which the heat medium pipe 12 can be embedded. The width and depth of the buried groove 11 are preferably substantially the same as the outer shape of the heat medium pipe 12 so that the heat medium pipe 12 buried in the buried groove 11 is not easily detached. It is also possible to make it slightly smaller or slightly larger than the outer dimensions of the tube 12. The aspect of the embedding groove 11 engraved on one surface of the base material layer 10 is appropriately determined according to the arrangement aspect of the heat medium pipe 12 embedded in the embedding groove 11. For example, in the case of the base material layer 10 in which the heat medium pipe 12 is arranged and laid in a straight line, the buried groove 11 may be cut in a straight line. On the other hand, in the case of the base material layer 10 in which the heat medium pipe 12 is partially curved and arranged and laid, the buried groove 11 may be cut into a shape combining a straight portion and an arc portion. It is preferable that the cross-sectional shape of the embedded groove 11 is U-shaped so that the cross-section when cut at right angles to the length direction of the embedded groove 11 is along the outer diameter of the heat transfer medium pipe 12. .

(D) Heat medium pipe In the heatable floor structure unit 600 of the present invention, the heat medium pipe 12 embedded in the base material layer 10 functions to dissipate the heat by circulating the heat medium in the inner space. It must be excellent in flexibility, mechanical strength, heat resistance, chemical resistance, and the like. Examples of the heat medium pipe 12 that exhibits such characteristics include a copper pipe, a crosslinked polyethylene pipe, a polybutene pipe, a polypropylene pipe, and a resin pipe in which a metal foil is embedded in the wall surface of the pipe. Among these, a crosslinked polyethylene pipe and a polybutene pipe are preferable. Although the diameter of the heat transfer medium pipe 12 varies depending on the performance required for the base material layer 10, the outer diameter is generally in the range of 5 to 30 mm and the inner diameter is in the range of 3 to 20 mm. As a heat medium which distribute | circulates the inside of this heat-medium pipe | tube 12, the antifreezing liquid containing warm water, water vapor | steam, ethylene glycol etc. can be mentioned. In addition, the heat medium circulated through the heat medium pipe 12 laid and constructed on the base material layer 10 is adjusted in temperature and pressure by a heat medium circulation device, and is distributed to the heat medium pipe 12 through the header. Let The heat medium circulation device is installed at a suitable place outdoors or indoors.

(2) Metal foil In the heatable floor structure unit 600 of the present invention, the metal foil 20 prevents the heat medium pipe 12 embedded in the embedded groove 11 of the base material layer 10 from jumping out of the embedded groove 11 and heat medium. It functions to spread the heat from the entire base material layer 10 evenly. Examples of the material of the metal foil 20 include an aluminum foil, a tin foil, a copper foil, and a stainless steel foil, but an aluminum foil is most preferable because it is excellent in terms of ease of manufacture and cost. The planar shape and size of the metal foil 20 are preferably the same planar shape and the same size as the base material layer 10, but can be smaller than the area of the planar shape of the base material layer 10. When the size of the metal foil 20 is made smaller than the area of the base material layer 10, at least a portion in which the heat medium pipe 12 is embedded is set to a size that can be covered. The thickness of the metal foil 20 varies depending on the material. However, if the thickness is too thin, the strength is insufficient and the glass foil 20 is not easily damaged. On the other hand, if the thickness of the metal foil 20 is too thick, the heat dissipation plate made of the base material layer 10, the buried groove 11, the heat medium pipe 12, and the metal foil 20 becomes heavy and the cost increases, which is also not preferable. From these viewpoints, the thickness of the metal foil 20 is preferably selected in the range of 10 μm to 2 mm.

(3) Non-woven fabric In the floor structure unit 600 which can be heated according to the present invention, the non-woven fabric refers to a natural fiber or synthetic fiber as a raw material in a mat or spongy state by an appropriate method, and then the adhesive or the fiber itself. This refers to a cloth-like substance produced by joining fibers together using the adhesive force of. The non-woven fabric has bonding points at various positions between the fibers, and has a feature that the strength increases as the bonding points increase. Nonwoven fabrics have a wide range of uses such as clothing materials, industrial materials, life-related applications, medical materials and sanitary materials, and in recent years, the market scale has been steadily expanding.

  Nonwoven fabric manufacturing technology is broadly divided into a technology for forming a thin sheet-like web made of fiber aggregates and a technology for bonding webs, and the technology for forming webs is further divided into a dry method and a wet method. The A non-woven fabric formed by a dry method has a soft texture similar to cloth, whereas a non-woven fabric formed by a wet method has a characteristic that it has a hard texture similar to paper. In the floor structure unit 600 that can be heated according to the present invention, since the nonwoven fabric preferably has a bulky feature, a nonwoven fabric manufactured by a dry method is used.

(A) 1st nonwoven fabric It is preferable that the thickness of the 1st nonwoven fabric 30 used with the floor structure unit 600 which can be heated of this invention is about 0.1-5 mm in an open state. If the thickness is less than 0.1 mm, it is too thin, and the effect of eliminating the noise generated by the first nonwoven fabric 30 is lost. On the other hand, if the thickness exceeds 5 mm, it is difficult to fix the floor heating panel at the time of laying, and the touch feeling is also deteriorated.

  Examples of the method for fixing the first nonwoven fabric 30 to the surface of the floor surface 50 include a method in which the tackers 60 and 60 are fixed at appropriate intervals and a method in which the first nonwoven fabric 30 is applied using an adhesive or a double-sided tape. . Here, the double-sided tape means one in which an adhesive is stuck on both sides of paper, cloth or film. When the first nonwoven fabric 30 is affixed to the floor surface 50 using an adhesive, the amount of the adhesive used when the first nonwoven fabric 30 is affixed is reduced as much as possible, It is preferable to leave bulky. Moreover, in sticking of this 1st nonwoven fabric 30, it is preferable that the 1st nonwoven fabric 30 can be fixed to the floor surface 50 simply and reliably rather than being easy to peel after sticking, and the method using the tuckers 60 and 60 in that sense is preferable. However, a method of fixing with a screw or a nail may be used.

  The first nonwoven fabric 30 includes an adhesive layer 71 that fixes the thin plate-like base material layer 10 in which the heat medium pipe 12 is embedded in the embedded groove 11 engraved on one surface and the floor surface 50. Adhere closely. By bringing the first nonwoven fabric 30 and the adhesive layer 71 into close contact with each other, it is possible to prevent slipping or sliding movement that occurs at the interface between the floor surface 50 and the base material layer 10, and noise caused by sliding or sliding movement. Temporary fixing of the material layer 10 can be reliably performed. Furthermore, since the process of fixing the base material layer 10 to the floor surface 50 is preferably easier, the material of the adhesive layer 71 used when fixing the base material layer 10 and the floor surface 50 is usually as follows. A double-sided tape or a hook-and-loop fastener is more preferable than this adhesive. Here, the hook-and-loop fastener is a tape that is affixed to the front surface side of the first nonwoven fabric 30 and has small protrusions that enter the gaps between the fibers of the bulky first nonwoven fabric 30. By allowing small protrusions to enter the gap, it is possible to prevent peeling, slipping or sliding movement that may occur at the interface between the first nonwoven fabric 30 and the base material layer 10. The hook-and-loop fasteners mentioned here are available under trade names such as Velcro (registered trademark of Kuraray Co., Ltd.) and Velcro (registered trademark of Velcro). As a matter of course, when using a hook-and-loop fastener, one surface side of the hook-and-loop fastener is attached to an upper or lower member as necessary.

(B) Second nonwoven fabric In the heatable floor structure unit 600 of the present invention, the second nonwoven fabric 31 stuck on the metal foil 20 may be the same as the first nonwoven fabric 30. The thickness is normally about 0.5 to 2 mm in the released state. If the thickness is less than 0.5 mm, the sound insulation performance is reduced, which is not appropriate. On the other hand, if the thickness exceeds 2 mm, a heat insulating structure is obtained, heat conductivity is deteriorated, and it is not suitable. The role of the second non-woven fabric 31 is to protect the metal foil 20 without impairing the heat transfer from the heat transfer pipe 12, and maintain the sound insulation on the finished floor surface 600 that can be heated, while the unevenness of the floor surface 50, etc. It contributes to the prevention of discomfort caused by.

(4) Resin sheet In the heatable floor structure unit 600 of the present invention, the resin sheet 40 disposed on the second nonwoven fabric 31 is adhered by the adhesive layer 74, and the base material layer 10 and the metal below the adhesive sheet 74. This contributes to protecting the foil 20 from damage and preventing water leakage. As shown in FIG. 6, when the cover material 80 is disposed on the resin sheet 40, and it becomes necessary to peel the cover material 80 from the floor surface 50 by reforming or the like, the resin sheet 40 includes the base material layer 10 and the metal foil. It functions so that only the cover material 80 can be peeled off without damaging 20.

  Examples of the resin sheet 40 include polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyolefin resins such as polycarbonate, polyethylene, and polypropylene, and polyamide resins such as polyamide 6 and polyamide 6/6. Among these, polyethylene terephthalate is preferable from the viewpoints of strength, ease of layer formation, compatibility with an adhesive, cost, and the like. The thickness of the resin sheet 40 is preferably in the range of 50 to 1000 μm, more preferably 150 to 500 μm. If the thickness of the resin sheet 40 is less than 50 μm, the above effect is impaired, which is not preferable. On the other hand, if the thickness of the resin sheet 40 exceeds 1000 μm, the sound insulation performance is deteriorated and the heat conductivity of the floor structure unit 100 that can be heated is impaired, which is not preferable.

(5) Surface Material The heatable floor structure unit 600 of the present invention can further dispose a surface material (finishing material) 80 on the resin sheet 40. Examples of the covering material 80 include carpets, decorative boards, and tatami mats. The heatable floor structure unit 600 of the present invention is particularly suitable for carpets. In addition, you may interpose the adhesive layer which consists of a weak adhesive agent, an adhesive, a surface fastener, etc. between the resin sheet 40 and the surface covering material 80 as needed. As a matter of course, when using a hook-and-loop fastener, the hook-and-loop fastener is attached to upper and lower substances as necessary.

  By interposing an adhesive layer made of a weak adhesive, a pressure-sensitive adhesive, or a hook-and-loop fastener between the resin sheet 40 and the surface covering material 80, slipping or sliding movement is caused at the interface between the resin sheet 40 and the surface covering material 80. It can be prevented from occurring. The intervening adhesive layer is a commercially available weak adhesive, pressure-sensitive adhesive, hook-and-loop fastener, or the like as long as it is a substance that can exhibit a function that does not cause slippage or sliding movement at the interface between the resin sheet 40 and the cover material 80. It can be used by appropriately selecting from the products.

3. Construction Method of Heatable Floor Structure Unit A construction method of the heatable floor structure unit 600 of the present invention will be described below with reference to FIG.

Furthermore, a resin sheet 40 is disposed on the second nonwoven fabric 31.
The above has been described mainly with respect to a mode in which a soft carpet is used as a covering material. However, when a hard wood floor finish is used, a base material layer between a plurality of floor heating panels or in a floor heating panel It is preferable to arrange so-called small joists at regular intervals. As a kind of small joist, wood harder than a base material, a low foaming resin molding material, a metal composite material, etc. are mentioned.
As an enforcement method, after laying the second nonwoven fabric, it is only necessary to fix it together with the floor heating panel with a screw or the like. Further, by appropriately fixing the cover material at the small joists, it is possible to prevent warping of the cover material.
