Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring.

[0002]

2. Description of the Related Art There have been various methods for heating a room. Gas stoves, electric stoves, electric carpets and the like. However, floor heating is the most excellent in consideration of indoor air purification, room temperature distribution, and the like. In this method, an electric heater or a tube of hot water is passed under the floor, so that the air is not contaminated, and the head can also be heated.

Usually, an electric heater or a hot water tube is provided below a flooring called a flooring, and the amount of heat is introduced into the room through the flooring. Flooring is a narrow, long floorboard that has been tongue-and-groove.
Usually, it has a cross-sectional structure of three or more layers, and in most cases, it is mostly finished with plywood as a base plate and the surface applied to painting.

[0004]

However, the conventional floor heating flooring has the following disadvantages.
That is, the flooring itself expands and contracts depending on the temperature,
In particular, warping occurs due to the temperature difference between the front and back surfaces. In addition, expansion due to moisture is large. That is, the wood loses its equilibrium moisture by heating and dries and shrinks. In addition, it expands and contracts due to uneven water entering from the surface. Furthermore, warping also occurs due to humidity, and the edges and four corners of the flooring rise. Of course, such a thing cannot be used. Therefore, floor materials that do not have the above-mentioned disadvantages have long been desired in the industry for heating.

It is desirable that the heating flooring be as thin as possible from the viewpoint of heat conduction, but there is a limit to the possibility of sagging or warping due to a load.

Further, there are disadvantages in that the natural material called flooring is expensive and has a cold touch.

[0007]

In view of the above situation, the present inventor has completed the flooring material of the present invention as a result of intensive studies, and the feature of the present invention is that the plastic sheet is made of aluminum sheet. It is fixed to a veneer plate covering both front and back surfaces, and a plastic plate is fixed to the back surface of the veneer plate, so that the overall thickness is 13 mm or less. Adhere to the plywood covering both front and back,
In addition, a plastic plate is fixed to the back surface of the veneer plate, and the overall thickness is reduced to 13 mm or less.

[0008] The plastic sheet usually has a thickness of about 0.1 to 0.5 mm, and its surface is subjected to various printings. For example, a flooring pattern, a natural single-plate pattern, or the like is used. Of course, other geometric patterns or characters on which characters are printed may be used. The material is polyvinyl chloride, polyolefin such as polyethylene, polyester, or the like, and any printed sheet may be used.

Further, the plastic mentioned here also includes linoleum. This is one of the hard surface elastic flooring materials, and is a flooring material in which linoleum composed mainly of oil, cork powder, pigment, and the like is pressure-bonded onto a cloth (hessian cloth).

In another embodiment, a fiber product is used as the surface material of the present invention. The fiber products include carpets and cloths, but are not limited thereto, and may be made of fibers. The fibers may be natural fibers, synthetic fibers, or semi-synthetic fibers.

Although the thickness of the aluminum sheet is not particularly limited, it is preferably 0.1 to 0.5 mm, and the surface may be subjected to rust prevention such as painting. The aluminum sheet serves to prevent moisture and moisture from entering the base. The inventor also experimented with a plastic sheet, but could not use a plastic sheet having a large expansion coefficient depending on temperature. Further, other metals are not preferable because of problems such as weight and cost. The aluminum sheet may be a commercially available one and does not require any special purity or precision.

This aluminum sheet prevents moisture and moisture from entering the plywood, which will be described later, which is the base material. Thereby, the above-mentioned adverse effects due to moisture can be prevented.

Further, if the aluminum sheet is firmly fixed to the veneer, the veneer can be prevented from warping from both sides. Therefore, it not only prevents the entry of moisture and the like, but also plays the role of preventing deformation. This is because the warpage of the plate is caused by the difference in linear expansion (mainly due to moisture) on the front and back surfaces, and the warpage does not occur unless the aluminum on the front surface extends.

Also, the difference in elastic modulus between wood such as veneer and aluminum is large, and it is hard to bend as compared with the one to which aluminum is attached. According to an experiment, when 0.135 mm of aluminum was adhered to both sides of a 10 mm veneer, the elastic modulus was equivalent to that of a 12 mm veneer. That is, the deflection when a load is applied is reduced.

[0015] The fixing method may be any method such as bonding, and the aluminum sheet and the veneer may be fixed at both ends so as not to slide, or may be fixed at the entire surface.
Any adhesive may be used as long as the adhesive can firmly bond the veneer and the metal.

The point of finding the double-sided cover made of aluminum is the point of the present invention.
There is also the advantage of helping heat conduction.

The plywood is a thin plate made of timber, and a plurality of the timbers are bonded with the fiber direction at right angles.
The thickness is not particularly limited, but is preferably about 1 to 10 mm. This plywood is a portion that becomes a base material of the present flooring material. Since the plywood has fibers at right angles, expansion and contraction due to moisture and temperature is very small. The use of a plywood with small expansion and contraction and the prevention of moisture from entering by an aluminum sheet also suppresses expansion and contraction in the thickness direction perpendicular to the fiber direction of the plate, and warpage caused by disturbances such as environmental changes. Is dramatically reduced.

The plastic plate fixed to the back surface of the veneer plate may be any type such as a rubber plate or a plastic plate. Those having flexibility are preferred. As the thickness,
About 2 to 6 mm is good. When this floor material is used together with floor heating, the floor material is usually laid on a heating device. However, there is no problem in the opposite case. In such a case, it is desirable to use a plastic plate having a relatively high heat insulating effect in order to prevent heat conduction from the heating device downward.

The reason why the overall thickness is set to 13 mm or less is to prevent heat conduction from below as little as possible.

The above five layers (plastic sheet, aluminum,
Any method can be used for laminating the veneer plate, the aluminum plate, and the plastic plate), but the simplest method of bonding with an adhesive is used.

In order to prevent displacement when laying down,
The side surface of the floor material may be subjected to tongue and groove processing similar to flooring. That is, one side of the floor material is processed into a female mold,
The other side is processed into a male mold.

The flooring material of the present invention is most suitable for floor heating as described above, but is not limited to heating and may be used between ordinary boards. Further, instead of being completely fixed with nails or the like, it may be merely mounted on a heating body for heating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. FIG. 1 shows the floor material 1 of the present invention.
FIG. 4 is a perspective view showing one example of FIG. It is composed of an aluminum veneer part 2, a plastic sheet part 3, and a plastic plate part 4. The aluminum veneer 2 has aluminum sheets 6 adhered to both sides of the veneer 5, and the plastic sheet 3 is a printed sheet of vinyl chloride. The plastic plate 4 is a rubber plate here.

FIG. 2 is a sectional view of a side portion of this example.
It can be seen that it is tongue-and-groove like ordinary flooring.

Next, the amount of change in expansion and contraction between this example and a conventional wooden flooring material was measured. The conventional flooring and the flooring of the present invention (FIG. 1)
) Were placed on the same heating section (hot water circulation type) with the same thickness (10 mm), and the total change in moisture absorption elongation from heat shrinkage to natural standing was measured. Room temperature 2
At a temperature of 5 ° C. and a surface temperature of 60 ° C. after heating, it was only placed without fixing with nails or the like. As described above, the amount of change is much smaller than the conventional one. When the variation amount reaches 3 mm, it is actually laid in many cases, so that there is no doubt that long-term warpage will have an effect.

[0026]

The present invention described in detail above has the following significant effects. Since the metal sheet is used for the floor material itself, the heat transfer coefficient is large, and when used as a floor material for floor heating, the thermal efficiency is good. Therefore, the heat source temperature can be lowered, which contributes to energy saving and reduces the risk of low-temperature burns in contact with clothes and futons. Since the front and back of the veneer are covered with an aluminum sheet, entry of moisture and moisture is prevented, and there is no warping or expansion and contraction due to them. Furthermore, when the aluminum sheet is fixed on both sides,
In addition to preventing the intrusion of moisture, the aluminum on both sides has a small expansion and contraction and is fixed so that it does not slip on the veneer, so the expansion and contraction (warpage) of the veneer as a whole or one side due to heat or other causes Is prevented. Since the surface is a plastic sheet or the like, various patterns are possible at very low cost. Because the plastic plate is fixed to the back surface, it is hard to slip and also exhibits a cushion effect. When the surface is made of textiles, it is warm and has a good feel.
