Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structural material and a floor structure using the same, and more particularly to a floor structural material and a floor structure suitable for a floor cooling / heating structure.

[0002]

2. Description of the Related Art There has been proposed a structure in which a heat source is arranged at a lower portion of a floor of a house and heating is performed by the heat source, or a heat storage medium is arranged at a lower portion of the floor to perform cooling and heating. Some are in practical use.

FIGS. 7 and 8 show floor cooling / heating structures proposed by the inventors (Japanese Patent Application Nos. 11-36789, 11-295699, 11-296679, etc.). The outline of this structure is as follows.

In FIGS. 7 and 8, bag-shaped water containers 50 are respectively arranged in spaces formed below a floor surface of a structure (house) by a partition member 52 called a joist. These water containers 50 are provided with a heat source such as an electric heater EH. At the time of heating, heat from a heat source such as an electric heater EH is transmitted to the water container 50, and the water W in the water container 50 circulates and flows due to the heat, so that the entire water container 50 is uniformly heated. The heat is radiated into the room via.

In addition, the temperature of the water W in the water container 50 is raised through the floor surface 51 by the sunlight radiated to the floor surface 51 in the daytime, and the power consumption of the electric heater EH is reduced by radiating the heat at night. Savings or eliminations are also possible. By arranging, for example, a pipe through which cold water passes outside the heat source for heating, it is also possible to perform cooling in summer using this structure.

In the floor cooling / heating structure having the above-described structure, the entire water container 50 is uniformly heated or cooled by the circulating flow of the filled water W. Therefore, neither the heating heat source nor the cooling heat source is And can be formed small.
Further, since the medium is water having a large specific heat, the room can be stably cooled and heated without frequently adjusting the temperature of the heat source.

[0007]

In the above configuration,
Both the heat radiation from the water W in the water container 50 and the storage of the heat of the sunlight radiated to the floor with respect to the water W are performed via the floor 51. Therefore, the higher the thermal conductivity of the floor surface 51 itself, the more effective both heat storage and heat radiation. However, the floor surface 51 is usually made of wood (plate material).

Wood is a porous material having a large number of voids, and air cannot easily pass through the voids. Therefore, wood is inferior to a resin foam having independent voids or cork close thereto. It can be said that the material has a considerably high heat retaining property and heat insulating property. In other words, wood is a material having low thermal conductivity.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a floor structure and a floor structure using the same. The floor structure is made of a material having high thermal conductivity. ,
And a floor surface material arranging portion for arranging a floor material (hereinafter, referred to as a “floor surface material” including the embodiments) constituting the entire surface or almost the entire surface of the floor, A floor structure using the floor structural material has a direct heat transfer portion serving as a part, and the floor structural materials are connected to each other, for example, and the floor surface material is arranged on the floor surface material arranging portion of each floor structural material. There is provided a floor structure material characterized by forming an integrated floor surface by arranging materials, and a floor structure using the floor structure material.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION A floor structural material is made of a material having high heat conductivity such as aluminum. The floor structural material is a structural material for supporting the entire floor surface, and the floor structural material constitutes a floor supporting structure, and the floor surface material is basically a floor supporting structure constituted by this floor structural material. It is only arranged for the floor, and it is directly different from a part of the support structure on the floor.

A heat source or a heat storage material is disposed below the floor structural material. During floor heating, heat from the heat source or the heat storage material is first radiated from the direct heat transfer portion of the floor structural material. The heat is also radiated from the floor surface material whose temperature has risen through this, thereby improving the thermal responsiveness (heat generation) of the floor surface to the heat generated by the heat source and the heat storage material as the whole floor surface. Similarly, when heat is transferred to the heat storage material below the floor via the floor, heat is first transferred to the heat storage material via the direct heat transfer unit.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In the figure, reference numeral 1 denotes a heat conductive floor structural material (hereinafter simply referred to as “floor structural material”) formed from a material having a high heat transfer property, as described later. On the other hand, it is an elongated member. That is, as described with reference to FIG. 6 described above, the floor structural members 1 are arranged so as to be extended across the partition members 52, and the longitudinal side edges of the floor structural members 1 are in close contact with each other. By disposing it in the upper space of the water container 50, a support structure for the floor surface is formed. The configuration in FIG. 1 shows a cross section of the floor structural material 1 arranged in this manner with respect to the partition member 52. In the arrangement state in FIG. It is.

The floor structural material 1 is a material having a good heat transfer property.
For example, a member made of aluminum and having a cross-sectional shape as shown can be formed relatively easily by drawing.

Each floor structural member 1 has the same shape. Reference numeral 1a denotes a main body of the flat floor structural material 1, and 1b denotes a first direct member vertically arranged on one side of the main body 1a in a vertical direction perpendicular to the main body 1a with respect to the main body longitudinal direction. The heat transfer section 1c is a second direct heat transfer section formed on the other side of the main body 1a in the longitudinal direction of the main body. Between the first direct heat transfer section 1b and the second direct heat transfer section 1c, a floor surface material arrangement section 1d for storing the floor surface material is formed.

By arranging the floor structural members 1 thus formed in close contact with each other as shown in the drawing, the entire water container arrangement space shown in FIG. 6 is covered, and a floor surface support structure is formed as a whole. I do. In the illustrated floor structure 1, a notch 1 b ′ is formed below the first direct heat transfer section 1 b, and the projection 1 is continuous with the second direct heat transfer section 1 c of the adjacent floor structure 1.
By mutually engaging with c ′, the engagement of each floor structural member 1 is strengthened. However, the formation of such notches and projections is not an essential component of the present invention.

Reference numeral 2 denotes a floor surface material housed and arranged in the floor surface material arrangement portion 1d of each floor structural material 1. Since a floor supporting structure is formed by arranging the floor structural material 1 in the illustrated configuration, the floor surface material 2 itself is merely a part of the floor supporting structure formed by the floor structural material 1. It is only placed and does not physically support the floor structure. For this reason, a material which was conventionally unusable due to its strength can be used as the floor surface material 2.

The floor surface is formed by arranging the floor surface material 2 for each floor structural material 1. That is, the floor surface is the second direct heat transfer section 1c of the floor structural material 1 adjacent to the first direct heat transfer section 1b.
A direct heat transfer portion consisting of: a floor surface material 2 adjacent thereto, another direct heat transfer portion adjacent to the floor surface material 2, a next floor surface material 2 adjacent to the direct heat transfer portion, and so on. The floor surface is formed such that the direct heat transfer section and the floor surface material 2 are alternately arranged.

The illustrated floor surface material 2 is wood,
Various materials are used instead of wood for the above-mentioned reasons.
As a result, it is possible not only to give a functional surface but also to give a decorative effect which has not been considered conventionally. For example, floor surface material 2
Glass, ceramic products, bricks, and the like may be used as materials that have hardly been used as flooring materials for wooden structures in the past.

On the other hand, a water container 50 filled with water W is disposed below the floor support structure constituted by the respective floor structural members 1.

In this configuration, for example, during floor heating,
The heat of water W, which is hot water, is used as the floor structural material 1 with high thermal conductivity.
(In the configuration shown, the first direct heat transfer section 1b and the second direct heat transfer section 1c are adjacent to each other), and the heat is immediately radiated from the floor. On the other hand, since the floor surface material 2 is usually made of a material having lower thermal conductivity than the floor structural material 1, the temperature rises later than the direct heat transfer portion. That is,
Conventionally, all the heat was radiated through the floor surface material 2, so that the responsiveness of the rise in the floor surface temperature to the heating of the water W was poor, but in this configuration, the heat is radiated directly from the heat transfer portion early. Therefore, the responsiveness of the rise in floor temperature is greatly improved. In a floor heating device of a type in which a floor surface is directly heated by a heat source such as an electric heater or hot water passing through a pipe, particularly high thermal responsiveness can be obtained.

On the other hand, as shown in the figure, a water container 50 is provided below the floor structure.
In the configuration in which is disposed, it is possible to effectively store heat in the water W as the heat storage material using this floor structure. That is,
When the floor is illuminated with sunlight, the room temperature may rise unnecessarily even in winter.
For example, if a situation in which the room temperature rises unnecessarily occurs even though the water container 50 filled with water W as shown in FIG. This means that the heat of the sunlight irradiating the surface is not sufficiently transmitted to the water W in the water container 50, and is radiated directly to the room.
On the other hand, in the illustrated configuration, a part of the floor surface is the floor structural material 1.
Of the floor surface material 2, even if the thermal conductivity of the floor surface material 2 is poor, the heat of sunlight can be transferred to the water container through the direct heat transfer portion and the main body 1 a which is in close contact with the water container 50. The heat is effectively transferred to the water W in the water 50, and the heat of the sunlight is stored in the water W with high efficiency, and can be effectively used for indoor heating at night, for example.

FIGS. 2 and 3 show a second embodiment. In the drawing, reference numeral 3 denotes a floor structural material in the present embodiment, and reference numeral 3a denotes a floor surface material arranging portion. Numeral 3b is a direct heat transfer section erected in the longitudinal direction on one side of the floor surface material arrangement section 3a. In this embodiment, the direct heat transfer part is the floor structural material 3.
Only one side is formed.

The direct heat transfer section 3b in this embodiment includes:
Means are provided for absorbing the expansion and contraction of each floor structural member 3 or the expansion and contraction of the floor structural member 3 and the floor surface member 2.
Reference numeral 3ba denotes a groove formed in the longitudinal direction of the direct heat transfer section 3a, and 3bb denotes a groove formed below the direct heat transfer section 3a.

On the other hand, reference numeral 3bc denotes a floor surface material engaging groove formed on a side edge of the direct heat transfer portion 3a on the floor surface material arrangement portion 3a side, and reference numeral 3bd denotes an adjacent floor structure material (reference numeral 3A in FIG. 3). ) Are ridges for engaging the floor surface material, which are formed on the side edge on the side where the 位置 is located.

In this configuration, each floor structural member 3 is arranged on each structural member such that the side edge not forming the direct heat transfer portion 3a is in contact with the direct heat transfer portion 3a of the adjacent floor structural member 3. You. In this case, the floor structural members 3 are fixed to the structural members by screws via the screw holes 3c shown in FIG. On the floor surface material 2, an engagement groove 2a and an engagement protrusion 2b are formed to engage with the floor surface material engagement groove 3bc and the floor surface material engagement protrusion 3bd, respectively. That is, the engaging ridge 2b is directly provided on the floor surface material engaging groove 3bc of the heat transfer portion 3a, and the engaging groove 2a is provided on the floor structural material 3 for each floor structural material 3 forming the floor supporting structure. Direct heat transfer part 3 of other adjacent floor structural material
engages with the ridge 3bd for engaging the floor surface material formed at the point a.

In the above configuration, the expansion and contraction of the floor structural members 3 are absorbed mainly by the deformation of the grooves 3bb. That is, in the configuration of FIG. 3, since the floor structural member 3 is screwed in the vicinity of the adjacent floor structural member 3A, the illustrated grooves 3bb mainly act to absorb expansion and contraction of the adjacent floor structural member 3A. The expansion and contraction of the floor structural material 3 itself is absorbed by the deformation of the groove 3bb on the other adjacent floor structural material 3B side (see FIG. 2).

On the other hand, expansion and contraction of the floor structural member 3 and the floor surface member 2 are mainly absorbed by the deformation of the groove 3ba. However, when the floor surface material 2 is wood, the floor structure material 3 expands in response to the heating of the floor surface, whereas the wood floor surface material 2 contracts in reverse. On the other hand, there is an advantage that the balance of expansion and contraction does not change much for the entire floor surface.

FIG. 4 shows a third embodiment. Reference numeral 5 denotes a spacer disposed directly between the heat transfer section 3b and the floor surface material 2, and is formed of rubber or a deformable material having the same effect as the rubber. By arranging the spacers 5, expansion and contraction of the floor surface material 2 and the floor structural material 3 are more effectively absorbed.
Although the groove 3ba shown in FIG. 3 is omitted in the illustrated configuration, the groove 3ba and the spacer 5 may be used in combination.

FIG. 5 shows a fourth embodiment. Reference numeral 6 denotes a floor structural material in the present embodiment. The floor structural member 6 is particularly configured to effectively absorb expansion and contraction between the floor structural members, and the direct heat transfer portions are provided on both sides in the longitudinal direction of the main body in the same manner as in the configuration shown in FIG. Heat transfer section 6b and second
When the direct heat transfer portion 6c is formed and each floor structural member 6 is arranged, the first direct heat transfer portion 6b of each adjacent floor structural member 6
And the second direct heat transfer section 6c are integrated to form one direct heat transfer section. Reference numeral 6a denotes a floor surface material arranging portion for arranging the floor surface material 2 in the same manner as in the above embodiments.

A groove 6ba is formed in the first direct heat transfer section 6b. On the other hand, a protrusion 6d is formed with respect to the second direct heat transfer portion 6c of the other floor structural material 6 which is in contact with the first direct heat transfer portion 6b, and an upper edge of the protrusion 6d is formed by the first edge. It is a Taber surface 6da that directly contacts and engages with the Taber surface 6bb below the heat transfer portion 6b. 6db is a groove formed in the horizontal direction with respect to the protrusion 6d. Reference numerals 7a and 7
b is an elastic body such as rubber fitted into each of the grooves 6ba and 6db. In the illustrated configuration, means for absorbing expansion and contraction generated between the floor structural material 6 and the floor surface material 2 disposed on the floor structural material 6 is not shown, but the means of each of the above embodiments is used. Is of course possible.

In the above configuration, when each floor structural member 6 expands, the groove 6ba of the first direct heat transfer portion 6b is deformed, and the tapered surface 6da of the protrusion 6d on the adjacent floor structural member 6A side. Is displaced downward along the Taber surface 6bb of the first direct heat transfer portion 6b, so that the groove 6db is deformed. That is, the expansion of each floor structural member 6 is effectively absorbed by the deformation of the two groove portions 6ba and 6db. In addition, since the elastic members 7a and 7b are fitted into the grooves 6ba and 6db, respectively, when the floor structural members 6 contract, the elasticity of the respective grooves 6ba and 6db causes the grooves 6ba and 6db.
The deformation of ba and 6db easily returns to the original state.

FIG. 6 shows a fifth embodiment. In each of the above embodiments, the direct heat transfer portion of the floor structural material and the floor surface material arrangement portion are integrally formed, but in this embodiment, the direct heat transfer portion and the floor surface material arrangement portion are separated from each other. ing.

First, in FIG. 6A, reference numeral 8 denotes a direct heat transfer portion, and reference numeral 9 denotes a support plate which functions as a floor surface material arranging portion and forms a support structure for the entire floor. It is fixed to. The direct heat transfer section 8 and the support plate 9 are made of a material having good heat conduction properties, such as aluminum, as in the above embodiments.

The heat transfer section 8 and the floor surface material 2 are directly disposed on the support plate 9 by fixing means such as screws (not shown) to form a floor surface. In this embodiment, the direct heat transfer section 8
Since it is formed separately from the support plate 9 functioning as a floor surface material disposing portion, for example, as shown in FIG. Is 2
For example, the area in which the heat transfer section is directly formed with respect to the entire floor surface can be adjusted, and thus the thermal conductivity of the floor surface can be adjusted according to the situation of each house.

As shown in FIG. 3B, the support plate 9 is abolished and the floor surface material is replaced with a floor material 2 'having the same strength as that of the conventional floor material. 'Can also be arranged directly on a structural material such as a joist.
