Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for constructing a floor heating structure, and in particular, the present invention relates to a construction method for a floor heating structure, and in particular, a method for installing a heat storage material and a heating wire, heating the heat storage material and gradually dissipating the stored heat. This invention relates to a construction method for a type of floor heating structure that keeps the floor warm.

[Conventional technology]

The indoor heating structure mainly consists of an N-thermal material with large latent heat and a heating wire (generally a coated heating wire) that heats the heat storage material.
A type of floor heating structure in which these are embedded in mortar or plaster and a floor finishing material is laid thereon to form a floor surface is disclosed in, for example, Japanese Patent Laid-Open No. 186134/1983.

In addition, there is also a floor heating structure in which a groove is formed on the top surface of the base layer, a heating wire is inserted into the groove, a heat storage material is laid on top of the groove, and a finishing material is laid on top of that to form the floor surface. .

As the heat storage material, for example, heat storage materials such as sodium sulfate decahydrate (also called mirabilite), calcium chloride, or sodium acetate, or various fireproof materials can be used, and the heat storage material is usually stored in a container such as a plastic case. used in the state.

The sodium sulfate decahydrate is, for example, 40 to 45k
It has a latent heat of cal/kg, and once it melts, it gradually releases a large amount of heat over a long period of time at a nearly constant temperature when it solidifies, so it maintains the room at a comfortable temperature for a long period of time (for example, about 10 hours) even after heating. (for example, 20 to 25°C).

[Technical problem to be solved by the invention]

By the way, in this type of floor heating structure, heating wires are buried inside a mortar layer formed on a floor such as a concrete slab, or heating wires are buried in grooves formed in advance on the upper surface of a base layer such as a mortar layer. After inserting the heat storage material, lay the heat storage material on top of it.
Furthermore, a construction method was adopted in which a floor surface was formed using floor finishing material on top of that.

However, among these conventional construction methods for floor heating structures, the method of inserting heating wires requires
In addition, it takes a lot of man-hours to insert the heating wire into the groove, and it is difficult to finish the finished surface to a smooth surface that will stabilize the N heating material. In the method of embedding the wires, it is easy to make the finished surface smooth, but if the heating wire breaks and needs to be replaced, the wire will be old unless the heating wire embedding layer (mortar or plaster layer) is completely destroyed. There was a problem in that it was not possible to take out the heating wire and install a new heating wire, and that repair work for the heating wire also required a great deal of labor.

Furthermore, the method of inserting the heating wire into the groove has the problem of low thermal conductivity because a void is created in the groove after the heating wire is inserted.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned conventional technical problems, and it saves work by eliminating the trouble of forming a groove into which a heating wire is inserted and the trouble of inserting a heating wire into each groove. Efficiency (can be done easily, and even if the heating wire is broken, repair work such as replacing the heating wire can be done by simply destroying the area where the heating wire is embedded, reducing the time and effort required for repair) The present invention provides a construction method for a floor heating structure that can reduce heat generation and minimize material waste, and also allows the heat storage material to be laid stably on top of the surface where the heating wires are laid, making it easy to smooth the surface. The purpose is to

The present invention is a construction method for a floor heating structure in which a heat storage material is heated to store heat and the floor surface is kept warm by dissipating the stored heat. After forming a base layer and arranging heating wires on the top surface of the base layer, pour mortar, plaster, sand, etc. at or near the top of the heating wires to a height that allows the position of the heating wires to be determined. The above object is achieved by a construction method in which a heat storage material is laid directly or through a thermal buffer material, and a floor finishing material is laid thereon either directly or through a base material.

〔Example〕

The present invention will be specifically described below with reference to the drawings.

FIG. 1 is a cross-sectional perspective view of a floor heating structure to which the construction method according to the first embodiment of the present invention is applied.

In FIG. 1, a base layer is formed by laying a heat-insulating layer 2 made of a heat insulating material such as foamed urethane on the upper surface of a building floor 1 made of a concrete slab or floorboard, etc. Heat generating lines 3 are arranged on the upper surface of 2 at predetermined intervals.

The heating wire 3 has a structure in which an electric heating resistance wire is covered with an insulating material such as plastic, and when energized, the surface temperature rises to about 50° C. to 100° C., for example.

The upper surface of the base layer 132 is a flat surface, and the heating wires 3 are placed on this flat surface in a predetermined arrangement,
Usually, it is fixed on the base layer 2 with an adhesive tape 4 or a needle member to prevent positional displacement.

After arranging the heating wire 3 on the base 1.2 in this manner, the heating wire 3 is placed at or near the top of the heating wire 3 to a height that allows the position of the heating wire 3 to be determined, that is, to a height that is approximately the same as the diameter of the heating wire 3. A flattening layer 5 of plaster, mortar or sand is cast.

A heat storage material 6 is laid on the upper surface of the flattening layer 5.

However, by laying a floor finishing board 8 such as a board, tile or carpet on the laying surface of this heat storage material 6, and constructing the above-described laminated structure on the floor 1 made of a slab of concrete or plaster, etc. A floor heating structure according to the invention is formed.

FIG. 2 shows a floor heating structure constructed in accordance with another embodiment of the present invention.

The underfloor heating structure shown in Figure 2 has an ITr? It has a structure in which the heating wire 3 is directly arranged without using the Z material, and the base layer is formed only by the floor 1.

The other parts in FIG. 2 are the same as those in FIG. 1, and corresponding parts are indicated by the same numbers, and detailed explanation thereof will be omitted.

FIG. 3 is a sectional view of a floor heating structure constructed using a construction method according to a third embodiment of the present invention.

In this embodiment, instead of constructing the heat storage layer 6 directly on the upper surface of the flattening layer 5 as in the underfloor heating structure shown in FIG. 9, and a layer of heat storage material 6 is disposed thereon.

The thermal buffer material layer 9 is a layer for preventing the heat storage material 6 from being locally rapidly heated and melted by the heating wire 3, and for uniformly heating and melting the heat storage material 6 at an appropriate temperature that is not too high. For example, it can be constructed of a heat-relaxing layer of mortar, plaster, etc., or a heat-relaxing IH material such as a plastic board, raw cloth, gold plate, etc.

The floor heating structure shown in Fig. 3 differs from the floor heating structure shown in Fig. 1 in that the heat-relaxing 1h material N9 is provided, and the other parts are substantially the same as the high-rise case shown in Fig. 1. Corresponding parts are indicated by the same numbers, and detailed explanation thereof will be omitted.

FIG. 4 is a sectional view of a floor heating structure constructed using a construction method according to a fourth embodiment of the present invention.

The floor heating structure shown in Figure 4 is different from the floor heating structure shown in Figure 3.
Furthermore, it has a structure in which a layer 10 of base material is additionally laid between the layer of heat storage material 6 and the layer 8 of floor finishing material.

The base material JiiIO has a function of uniformizing the temperature distribution of the indoor floor surface F and protecting the heat storage material 6, and can be formed of, for example, a layer of mortar.

The floor heating structure shown in FIG. 4 differs from the floor heating structure shown in FIG. 1 in that the base material layer 10 is provided, and the other parts are substantially the same as the structure shown in FIG. Corresponding parts are indicated by the same numbers, and detailed explanation thereof will be omitted.

FIG. 5 is a sectional view of a floor heating structure constructed using a construction method according to a fifth embodiment of the present invention.

In the floor heating structure shown in Fig. 5, heating wires 3 are placed on the base layer 2.
is placed and buried to almost the same level with a flattening layer 5 of mortar, plaster, or sand, and then a first layer is placed on top of it.
Rather than directly as shown in the figure, a heat equalizing plate 11 is installed, and a layer of heat storage material 6 is provided on the heat equalizing plate 11.

This heat-uniforming plate 11 is for uniformizing the distribution of heat transferred to the N-heating material 6 when the heating wire 3 is energized to heat and melt the N-heating material 6. Made of a good conductor of heat, such as a metal plate (aluminum, copper, iron, etc.).

The floor heating structure shown in FIG.
This is different from the floor heating structure shown in the figure, and the other parts are substantially the same as the structure shown in FIG.

In addition, in the layer of the heat storage material 6 having the structure shown in FIGS. 1 to 5, after laying a plurality of N heat materials in a predetermined arrangement, each heat storage material 6 is
If there is a gap between them and the gap is quite large, a spacer can be interposed. The spacer may be made of any suitable material including plastic board, mortar board, gypsum board, and even waste wood.

When using the above floor heating structure, the heating wire 3 made of a coated electric heating resistance wire is energized, and the heat generated at that time (for example, 50 to
100°C) to heat and melt the heat storage material 6 (for example, about 30°C).
°C).

When the heat storage material 6 is completely melted, the power supply to the heating wire 3 is stopped.

Thereafter, due to the latent heat dissipated as the N heating material 6 gradually solidifies due to the ambient temperature, the floor surface F is heated for a considerable period of time (
at a predetermined temperature (e.g. 21°C) over a period of time (e.g. 10 hours).
It can be kept warm.

When the heat dissipation of the heat storage material 6 is almost completed, the heating wire 3 is energized to heat and melt the heat storage material 6, so that heating can be further continued.

According to the embodiment described above, the following effects can be obtained.

(i) The heating wire 3 is arranged on the upper surface of the base layer formed by laying the heat insulating material 2 on the floor 1 itself or on the floor 1, and the flattening F
Since the heating wire 3 is held by casting i5, there is no need to insert the heating wire into the groove on the surface of the base layer as in the conventional method, and groove forming is not necessary, and the work of inserting the heating wire 3 into the groove is simplified. We were able to eliminate this and improve the ease of implementation.

(ii) The flattening layer 5 is cast to a height within the range where the position of the heating wire 3 can be determined, so when replacing the heating wire 3 due to breakage etc., when lifting the heating wire, only the portion of the heating wire can be covered with mortar etc. can be removed and replaced.

Therefore, it is no longer necessary to peel off the entire mortar layer as in the past, making it possible to achieve economical use of mortar and improvement in the efficiency of repair work.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a base layer is formed by laying a 17I thermal material, mortar, plaster, etc. on the floor as it is or on the floor, and heating wires are arranged on the upper surface of the base layer. A flattening layer of mortar, plaster, sand, etc. is placed at or near the top of the rear heating wire to a height that allows the position of the heating wire to be determined, and a heat storage material is laid on top of it directly or via a thermal buffer material. Since we use a floor heating structure construction method in which floor finishing material is laid directly or through a base material on top of that, the work of inserting the heating wires into the grooves can be eliminated, and moreover, it can be used on new lines, etc. When replacing a heating wire, the mortar or the like can be removed and repaired only on the heating wire portion, and a construction method for a floor heating structure with excellent workability and repair workability can be obtained.
