Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an underfloor heat storage layer .
[0002]
[Prior art]
In recent years, in buildings such as houses, concrete is often used from the viewpoint of soundproofing, fireproofing, durability and the like.
[0003]
[Problems to be solved by the invention]
However, a building using concrete has a problem that moisture in the room and under the floor is difficult to be discharged to the outside due to its high hermeticity. In addition, chemical substances released from concrete itself and chemical substances contained in adhesives used for wall cloths and flooring materials are difficult to be discharged to the outside, which may adversely affect the human body.
In addition, since concrete has a low heat storage property, there is also a problem that heating efficiency is poor for high sealing performance.
[0004]
Therefore, by mixing a certain amount of carbon material (activated carbon, charcoal, bamboo charcoal, etc.) into the concrete, various characteristics of the carbon material (air purification and deodorizing action, moisture and chemical substance adsorption action, insect control and prevention) Concrete has been proposed in which the above-mentioned problems are solved by utilizing a mold action, a far-infrared emission action, and the like.
However, when a large amount of carbon material is mixed in the concrete, the strength is lowered. On the other hand, if the amount of mixed carbon material is small, there is a problem that the characteristics of the carbon material as described above cannot be obtained sufficiently.
[0005]
The subject of this invention is considering the above-mentioned problem and is providing the underfloor thermal storage layer which has a dehumidification effect, the adsorption effect of a chemical substance, a thermal storage effect, etc.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the invention described in claim 1 contains gypsum and a carbon material, and at least contains silicon, magnesium, and aluminum as components, and a ceramic material obtained through a sintering process. The underfloor heat storage layer is characterized by using a building material and concrete, and having a heater inside .
[0007]
According to the invention of claim 1, since the building material contains gypsum and carbon material, the deodorizing effect, dehumidifying effect, chemical substance adsorption effect, far-infrared emission effect, negative ion emission effect of the carbon material. In addition, an electromagnetic wave shielding effect and the like can be obtained. Moreover, since the heater is provided inside the underfloor heat storage layer, the heat storage effect can be further enhanced by the building material heated by the heater. Moreover, the salt content in the concrete used for a part of the underfloor heat storage layer can be absorbed by the ceramic material or the carbon material, and the deterioration of the concrete can be prevented.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the underfloor heat storage layer using the building material and concrete of the present invention will be described.
Building materials mainly consist of gypsum and carbon materials, and further contain a small amount of ceramic materials.
As the gypsum, for example, natural gypsum mainly composed of calcium sulfate dihydrate and general gypsum such as chemical gypsum are used.
[0017]
As the carbon material, for example, a well-known charcoal such as charcoal or bamboo charcoal is used. Bincho charcoal is preferred as the charcoal. Bincho charcoal is particularly excellent in deodorizing effect, dehumidifying effect and far-infrared effect because of its small pores among charcoal.
Bamboo charcoal has more pores and more minerals than charcoal, so by using bamboo charcoal as a carbon material, deodorizing effect, dehumidifying effect, chemical adsorption effect, far-infrared emission effect, even better than charcoal, A negative ion emission effect, an electromagnetic wave blocking effect, and the like can be obtained.
Bamboo charcoal and charcoal may be mixed as a carbon material, and the mixing ratio of bamboo charcoal and charcoal in this case is not particularly limited, but may be about 2: 3 to 3: 2, for example.
[0018]
Ceramics, which contain at least silicon, magnesium and aluminum as components and are obtained through a sintering process, are manufactured as follows.
First, a raw material inorganic material made of silica, magnesium oxide, alumina, zirconia, or the like is pulverized into a powder having a diameter of 10 microns or less. As the raw material inorganic material, for example, a mixture of each oxide at a ratio of 50% silica, 20% magnesium oxide, 20% alumina, and 10% zirconia can be suitably used. Next, the obtained powdery inorganic substance is sintered at 400 to 800 degrees for 4 to 8 hours.
[0019]
A sulfuric acid aqueous solution (30% concentration) having a weight three times that of the powder is added to the sintered inorganic powder and stirred. Thereafter, the liquid part is taken out, and caustic soda (sodium hydroxide aqueous solution, concentration 30%) having the same weight as the aqueous sulfuric acid solution is added to the liquid to neutralize it. The neutralized liquid thus obtained is removed and dried by spray drying to obtain an intermediate powder.
Next, water is added to the intermediate powder to obtain a mud. The mud is circulated for several hours to several tens of hours while applying a pressure within a certain range, for example, a pressure of 100 to 500 Pascals. And if it is made to dry after a circulation process, the ceramic used by this invention will be obtained.
[0020]
A ceramic material can be obtained by kneading the ceramic produced as described above into a heated synthetic resin and then forming it into granules. As the synthetic resin, many general-purpose synthetic resins can be used. For example, polyethylene or polypropylene can be used. Here, the grains of the ceramic material are formed into a long and thin shape having a diameter of about 1.3 mm and a height of about 2 mm, for example. Further, the weight ratio of the resin to the ceramic is preferably about 70:30 to 95: 5.
[0021]
The building material of the present invention can be obtained by charging the gypsum, carbon material and ceramic material into a container containing a predetermined amount of water and stirring.
The mixing ratio of gypsum and carbon material constituting the building material is preferably about 5: 2 by weight. The amount of the ceramic material in this case may be extremely small compared to the amount of gypsum and carbon material. For example, the mixing ratio of gypsum, carbon material, and ceramic material is about 5: 2: 0.1 by weight ratio. However, the above-described effects of the ceramic material can be sufficiently obtained.
[0022]
If the mixing ratio of the carbon material is increased, the strength of the building material is lowered, and if the mixing ratio of the carbon material is further decreased, the above-described effect of the carbon material cannot be sufficiently obtained.
Moreover, the mixing ratio of water when the mixing ratio of the gypsum and the carbon material is about 5: 2 can be appropriately adjusted according to the use of the building material. For example, when the building material is disposed on the foundation of the building, the viscosity of the building material and the time until the surface of the building material starts to solidify (about 10 minutes to the time when the gypsum, carbon material and water are mixed) In view of the above, the mixing ratio of gypsum, carbon material and water is preferably about 5: 2: 4.
When the mixing ratio of water is increased, it takes a long time until the surface of the building material is solidified, and the carbon material contained in the building material floats on the surface of the building material, which is not preferable. Moreover, when the mixing ratio of water is reduced, the time until the surface of the building material is solidified is shortened, and workability is deteriorated.
[0023]

When the position is reached, a sheet heater 20 (see FIG. 1) and a linear heater 21 (see FIG. 2), which are generally known for floor heating of a house, are disposed and fixed. .
[0025]
Then, pouring building material 16 to be substantially flush with the upper surface of the joists 12, the surface is solidified in a state in which leveled and this upper face, in Rukoto to dispose the thin plate-like mortar or concrete, a heater The laying operation of the underfloor heat storage layer 10 including the heater 20 or the heater 21 is completed.
Furthermore, the floor of the house is formed by spreading floor finishing materials such as flooring.
[0026]

In addition, it is possible to obtain moisture and chemical substance adsorption effects and antibacterial effects, and to have a positive influence on the human body due to the negative ion release effect.
[0027]
In addition, since the time until the surface of the building material is solidified can be about 10 to 20 minutes, it is possible to prevent deterioration of the quality of the building material and to improve the workability of various operations using this building material. It can be improved.
Moreover, since a building material is used as a part of underfloor heat storage layer, the heat storage effect of the underfloor heat storage layer can be enhanced. Moreover, since the heater is provided inside the underfloor heat storage layer, the heat storage effect can be further enhanced by the building material heated by the heater. Moreover, the salt content in the concrete used for a part of the underfloor heat storage layer can be absorbed by the ceramic material or the carbon material, and the deterioration of the concrete can be prevented.
[0028]
Moreover, generation | occurrence | production of a termite can be suppressed by using the building material for a wooden house by the high dehumidification effect of a building material.
Further, since the ceramic material is not ceramics alone but ceramics mixed with a resin, it can be processed into a desired shape, and the amount of ceramics used can be suppressed and the cost can be reduced.
[0029]

[0030]
Further, as a method of laying the underfloor heat storage layer 10, for example, a mud-like building material 16 having a high viscosity generated by reducing the amount of water added without using the joist 12 for supporting the side surface of the building material 16 is used. You may form the underfloor thermal storage layer 10 using.
The structure of the underfloor heat storage layer 10 is not particularly limited as long as the building material 16 and the concrete are disposed on the upper part of the floor foundation 30 of a building such as an office or a house.
