Description

  The present invention retrofits an existing house building, particularly a wooden house that has been built for several to ten years or a house that has not been provided with floor heating equipment, etc. A method is provided.

Wooden houses are airtight at the beginning of construction, and the parts between windows and window frames, pillars and walls are tight and airtight, but various members shrink and deform over time. In many cases, gaps are gradually generated. Accordingly, the temperature often decreases due to outside air entering a room that was warm at the beginning of the new construction. In addition, several earthquakes have been encountered over the years, the entire house is shaken, and there are gaps in each part, making it difficult to prevent outside air from entering the room.
Oil heating stoves are often used as the indoor heating means in such Japanese houses. However, oil stoves pollute indoor air and can cause fires and burns. Furthermore, since kerosene is required, the heating cost is considerably high. In addition, there is a traditional kotatsu as a local heating method, but this is suitable for heating when a family gathers at night, etc., but there are people with different ages and interests and behavioral ranges like the present age. It is totally unsuitable for gathering and warming, and above all, there are drawbacks that the place of warming is limited and life is restricted.
Air conditioners are used as a method of heating and cooling cleanly while using the room widely. In the case of heating, the air conditioner heats the air in the room by ejecting heated air from near the ceiling. Even if the air in the ceiling part can be warmed, it cannot be heated up to the air in the living part of the person, a large temperature difference occurs between the ceiling part and the vicinity of the floor, and the operation time of the air conditioner is long. However, it is not efficient heating.
On the other hand, floor heating devices are often installed from the beginning in newly built houses and newly built condominiums, and recently it can be installed as standard equipment because it can reduce heating costs by storing heat using night electricity. It has come to be. A floor heating device installed in a concrete structure such as a condominium is composed of a heater or a heater and a heat storage material provided in a floor structure below a flooring.
As heating means of the floor heating device, there are hot water heating and electric heating. In the case of a hot water type floor heating device, it is necessary to always make hot water with a boiler and supply it to the room. In addition, in the case of supplying heat energy by hot water, a large temperature difference does not occur between the temperature of the supply source of 80 ° C. and the temperature of 25 ° C. at which the heat energy is released and returned to the boiler after heating. I do not get. Therefore, it has a thermal effect on the floor structure including the floor base material and the floorboard, especially when the floorboard is distorted and deformed, and when the floorboard is chemically treated, it generates gas of chemical treatment materials such as formaldehyde. And cause sick house syndrome.
On the other hand, an electric floor heating device uses various sheet heating heaters, and when the switch is turned on, the heater generates heat on the whole floor surface and exerts a floor heating effect. It can be kept at a low temperature, and the problems of the sick house syndrome and the deformation of the flooring caused by heating the flooring to a high temperature can be avoided.
In addition, in the case of a floor heating apparatus using a heat storage material, since inexpensive nighttime electric power can be used as described above, the heating cost is reduced to about 1/3 to 1/5 as compared with hot water heating. In addition, since the human body can be warmed by far infrared rays radiated from the floor surface, the human body receives a large amount of heat, can be heated to the inside of the human body, can be comfortably heated, and does not disturb indoor air, so it is extremely hygienic. It is also a target.
Comparing the heating effects and heating costs in the various heating methods, it is more hygienic and efficient to heat using an electric floor heating device even in an old house, and there is no problem in maintenance. I understand that.
Regarding a floor heating unit in a Japanese style house, an invention in which a channel having a U-shaped cross section is prepared, a heat insulating material, a heater, and a heat storage material are accommodated inside the channel, and a floor board is laid on the channel to constitute a floor heating device. It has been proposed (see, for example, Patent Document 1).
Japanese Patent Publication No. 3-50177

(Problems when retrofitting floor heaters)
When constructing a floor heating system in an existing house, in most cases, the construction owner often receives great opposition. For example, if a floor heating system is assumed to be installed in a living room with a floorboard, the floorboard in the living room is a highly attached family that has been waxed and polished by housewives with sweat for many years. Enjoy the atmosphere of the entire room, including the brightness of the floorboard and furniture, paintings, and other decorative items, and replacing the floorboard is to remove the floorboard that forms part of life. For a housewife who has refined over the years, it is truly unbearable.
In addition, when retrofitting a floor heating device, it is necessary to move heavy furniture such as indoor furniture, particularly a piano or a bookcase, and to secure a storage location thereof.
In addition, if the existing floorboard is left as it is, a floor heating device is installed on the floorboard, and a new floorboard is stacked on the floorboard, the floor height increases by 20 to 30 mm and the door opens and closes. In addition, a step is generated between the living room and the hallway or another room, making it difficult to secure barrier-free.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side sectional view showing a part of a house, and FIG. 2 is a perspective view showing a state in which the lower surface of the floor is looked up from under the floor.
For example, the house 1 forms a foundation 2 (cloth foundation or other type) in a predetermined shape on the ground 3, and forms a bundle foundation 4 inside the foundation 2 on the crossing of the grid, A bundle 5 is set up on the base 2 and a base 6 (90 × 90 mm square) is arranged on the upper end of the foundation 2 according to the outer shape of the house. A pillar 1a is set up on the base 6 and the base 6 is placed inside the base 6. The large pull 8 (90 × 90 mm), that is, the interval L of the bundle 5 is disposed at 909 mm, the joist 9 (45 × 45 mm square) is disposed on the upper surface of the base 6 and the large pull 8, and the base plywood 10 is disposed thereon. And the finishing material 11 (flooring) is spread to complete the floor structure.
(Underfloor dimensions: working space)
An example of the dimension relationship under the floor will be described. Since the height H1 between the floor surface of the first floor and the ground 3 is defined as “500 mm or more” by the “Building Standards Law”, the thickness h of the concrete foundation 2a When the thickness of the base plywood 10 and the finishing material 11 is 12 mm, the height H3 to the lower surface of the concrete foundation 2a and the joists 9 is 381 mm. In addition, the distance H4 between the concrete foundation 2a and the lower surface of the large draw 7 is 291 mm. Of course, these dimensions vary depending on the design and structure of the house, but because of the regulations of the Building Standard Law, they do not deviate greatly from the above-described exemplary dimensions.
(Place of floor heating equipment construction work)
The distances “H3” and “H4” mean the work space used in the present invention.
As shown in FIG. 14, the floor heating apparatus is constructed such that the worker M rides on the cart C shown in FIG. 13 and moves on the concrete floor 2 a as appropriate, while the worker M spreads on the upper surface. While looking at the ceiling of the joists 9 and the base plywood 10 and the like, the following members of the floor heating device D are assembled so as to be stuck to the ceiling one after another.
As shown in the floor plan of FIG. 3, the heating section 15 in which the floor heating device D is installed is formed in the living dream 13. The assembled state of the floor heating device D is shown in FIG. 4.
The floor heating device D shown in FIG. 4 shows a structure using a heat storage material, and covers the three surfaces of the base plywood 10 and the joist 9 with a soaking plate 16 such as a galvanized iron plate, a copper plate or an aluminum plate. To fix. A heat storage material (formed in a thin mat shape) 17 and a sheet heater 18 are disposed between the two joists 7 (distance 303 mm) on the lower surface of the heat equalizing plate 16.
When the soaking plate 16 is fixed to the base plywood 10, a double-sided adhesive tape is used, or a small nail is driven and fixed to a portion where no electrical problem occurs. Further, it is preferable to fix the heat storage material 17 and the sheet heater 18 by using a double-sided adhesive tape as appropriate.
Next, a heat insulating layer 20 made of a synthetic resin foam is disposed so as to cover the lower surface of the sheet heater 18 and the lower surface of the heat equalizing plate 16 disposed around the joists 9, and the heat insulating layer 20 is formed on the heat insulating layer 20. The floor heating device D is assembled on the lower surface of the floor structure by interposing a washer in the cylindrical recess 20a and fixing with a fixing member such as a wood screw 21.
FIG. 5 is a modification of FIG. 4 and shows the structure of a simple floor heating device D using a soaking plate 16 and a planar heater 18.
(Use of heat storage material)
The heat storage material used in the present invention is a latent heat storage material, which melts at its melting temperature and stores the latent heat of melting, and when it is cooled and solidified while releasing the heat energy, the latent heat of fusion is stored. To be released. As this heat storage material, for example, a material mainly composed of sodium sulfate (anhydrous bow glass) shown in Japanese Patent Nos. 2929418, 3390238, 3334765 and the like can be effectively used.
Further, as another heat storage material, a product name “HS capsule” manufactured and sold by Mitsubishi Paper Industries, Ltd. can be used. This heat storage material is formed into microcapsule particles, and a material in which a mixture of this and water is sealed in a bag made of a synthetic resin sheet is used. Further, in some cases, it can be used as a concrete structure in which the microcapsules are mixed with concrete.
The great merit of using a heat storage material is that it uses much less expensive nighttime power than daytime power, melts the heat storage material at night to store heat energy, and uses this heat energy during daytime heating. Can be released and heated. In the case of the floor heating method using nighttime electric power, it can be reduced to about 1/3 to 1/5 compared with the heating cost of hot water heating, and extremely efficient floor heating can be performed.
(Surface heating heater)
Various types of planar heaters have been proposed. As this heater, there are those using metal wires, copper and aluminum, and in some cases using metal foils such as stainless steel, which use heat generated by the electric resistance of the metal. Those using resistors have a characteristic that their resistance value decreases as the temperature rises, so there is a risk of heat generation to a high temperature due to overheating. Therefore, it is necessary to avoid this type as much as possible.
As a preferable planar heater, there is a trade name “Plaheat” manufactured and sold by the applicant of the present invention. This heater uses an olefin-based thermoplastic resin and carbon as a base material, is formed into a sheet shape under special conditions, and a thin layer containing a large amount of carbon is formed on the surface of the sheet. This heater has a so-called PTC characteristic in which the resistance value decreases as the temperature rises, and the applicant has been used safely in various facilities and ordinary houses for over 30 years.
