Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to so-called floor heating in which heating is performed from the floor surface by circulating hot water, a heat medium liquid or the like under the floor, or by placing a heating material such as a heating wire under the floor, The present invention relates to a buried panel used for fixing a buried position of a heating wire connected to a pipeline for circulating a heat medium liquid and a power source, and a method of using the buried panel.

[0002]

2. Description of the Related Art Conventionally, in order to realize floor heating, heat must be radiated under the floor by circulating hot water or a heat medium liquid under the floor. No pipe, so-called seamless pipe, was used. The seamless pipe is linearly embedded for a predetermined length while being bent or curved at its end to change its direction, and is further embedded linearly so as to be arranged in a wavy shape. Therefore, a buried panel was used to preconfigure this wavy shape. That is, the buried panel that has been conventionally used has a plurality of grooves formed by combining straight lines and arcs, and these grooves are provided with a width that allows only one seamless pipe to be buried. Therefore, as a method of using such a buried panel, regardless of whether it is a straight line or a curved line forming a wavy shape, it is used by arranging the seamless pipes by accommodating all the seamless pipes in the straight or arc grooves. It had been.

[0003]

However, in the buried panel and the method of using the buried panel as described above, when the seamless pipe is provided in a straight line, the seamless pipe can be arranged relatively easily. Since it is arranged in a wavy shape, it is naturally required to be arranged in a curved shape, and it is extremely difficult to bend the seamless pipe to match the groove shape provided in the arc at that location. It was difficult and required skill. Further, this is not limited to the seamless pipe made of copper, and was the same when a polyethylene pipe or a polybutene pipe was used. Furthermore, when using polyethylene pipes or polybutene pipes, since these materials have a large expansion and contraction rate due to temperature changes, it is necessary to circulate the heat transfer medium liquid even if the installation work is completed in line with the grooves. Since the pipe is stretched as the temperature of the pipe rises, the length of the pipe and the length of the groove are different from each other, and the stability of the arrangement position is lacking. The above is the same in the case of floor heating in which a heat storage material is additionally provided in addition to the heating element.

In view of the above points, it is an object of the present invention to provide a buried panel which can easily dispose a seamless pipe and can accommodate expansion and contraction of the pipe, and a method of using such a buried panel. .

That is, the floor heating can be performed without selecting a construction site. Further, even when the pipe is made of a material that expands and contracts, the bent portion in the box is not restricted by the groove or the like, and the extended portion can be absorbed by sufficient play.

Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, as shown in FIG. 1, side plates 2, 3, 4, 5 are provided on the periphery of a bottom plate 1 of a square plate material, and the bottom plate 1 and the side plates 2, 3, 4, 5 are All of them are integrally formed of a foamed resin having a low foaming rate.

The buried panels 10 are arranged immediately below the finishing floor 14 without any gap, and the grooves provided in the buried panel 10 are arranged so as to be continuous with each other. The surface finish floor 14 is then nailed. The embedded panel 10 is made of a foamed resin having a low foaming rate as described above and is relatively hard, so that it can be struck by a nail or the like. Further, when the nail or the like is hammered in, the position where the groove of the embedded panel 10 is not provided is naturally selected. Further, as shown in FIG. 3, the seamless pipes 15 are arranged side by side in a wave shape in the room A, and are radiated exclusively by the linear seamless pipes 15a, and the arc-shaped seamless pipes 15b are provided in the room A.

The linear panel 20 is made of a synthetic resin foam having a low foaming rate like the above-mentioned embedded panel, and has two parallel grooves 21 and 22 provided in advance. The distance between the two grooves 21 and 22 is double the distance from the grooves 21 and 22 to the edge, and when the linear panels 20 are arranged in parallel, the distance between the grooves is constant. It is like this. Therefore, if the pipes of the heat generating material and the seamless pipe are provided by the two types of panels 10 and 20, the heat generating material and the seamless pipe housed in the groove of the linear panel 20 are the through grooves 6, 7 of the buried panel 10. , 8 can be passed. for that reason,

The second buried panel 10b is arranged on the opposite side of a. At this time, by connecting the through groove 8a on the right side of the second embedded panel 10b to the groove 22a of the linear panel 10a, the through groove 6 on the left side of the second embedded panel 10b is formed.
b will be continuous with one groove 21b of the second linear panel 20b. In this way, the ends of the grooves 21, 22 of the linear panel 20 are provided so as to be continuous with the left through groove 6 and the right through groove 8 of the same buried panel on the same side. With the above, as shown in FIG.
The direction of the heat generating material 30 and the seamless pipe 40 can be changed inside each of the buried panels 10a, 10b, 10c ..., and a wavy pipe path can be easily arranged. Further, when the direction of the heat generating material 30 and the seamless pipe 40 is changed inside each of the buried panels 10a, 10b, 10c, ..., there is no member that restricts the arc-shaped groove or the pipeline, so that the heat generating material can be freely changed. The 30 and the seamless pipe 40 can be curved and embedded. Therefore, it is possible to improve the work efficiency and reduce the work cost without requiring any skill in such burying work.

Next, a second embodiment will be described. In this embodiment, as shown in FIG. 6, the side plates 102, 103, 10 are
Through holes are similarly provided in each of the side plates 102, 103, 104 other than the one side plate 105 among the side plates 104, 105. With such a configuration, as shown in FIG. 7, the linear panels 120a and 120b are
The buried panels 110a, 110 are arranged so as to be continuous with.
By arranging b, ..., The heat generating material 130 and the seamless pipe 140 can be easily embedded in a continuous state. Further, among the side plates of the buried panels 110a, 110b, ..., The side plates 103, 104 that do not contact the linear panels 120a, 120b ,.
Will be continuous through the through groove. Therefore, by using this continuous portion, it is possible to dispose the heat generating material 130 and the seamless pipe 140 up to the embedding position up to the embedding position (110a, 1 in FIG. 6).
(See 10c below).

Next, a third embodiment will be described. This embodiment is a slight modification of the second embodiment, and is shown in FIG.
As shown in FIG. 5, notches 252, 253, 25 are formed on the upper inner edges of the side plates 202, 203, 204, 205, respectively.
4,255 are provided. Of these, the notch portion 255 provided in the side plate 205 not provided with the through groove has a continuous linear shape, and the other side plates 202, 203, 204 are provided.
The cutouts 252, 253, 254 provided in the are intermittent. Then, the cutouts 252, 253, 25
4, 255 are provided from the surface of the bottom plate 201 to a height corresponding to the diameters of the heat generating material and the seamless pipe, and further, as shown in FIG. 9, the cutouts 252, 253.
A thin lid 260 that fits in a quadrangle formed by 254 and 255 is provided. When the opening is closed by the lid 260, the lower surface of the lid 260 is brought into contact with the heat generating material 230 and the seamless pipe 240. Due to the presence of the lid body 260, the heat of the heat generating material 230 and the seamless pipe 240 is transferred to the upper surface of the lid body 260 through the lid body 260, and this heat can also be used for floor heating. By forming the embedded panel 210 with a metal material, the heat of the heat generating material 230 and the seamless pipe 240 can be transferred to the lid 260 via the embedded panel 210, as shown in FIG. 9B. . Since the finishing floor is provided on the lid 260, the heat can be efficiently transferred to the lid 260, so that floor heating can be efficiently performed.

Next, an example of a method of using only the third embodiment, that is, a method of using the buried panel 210 by itself without using the linear panel will be described. As shown in FIG. 10, this usage is performed by using the heat generating material 230 and the seamless pipe 24 through any of the through grooves of the side plates 202 to 204.
0 is disposed inside the buried panel 210, and the side plate 202
To the buried panel 21 through any of the through grooves
It returns to the outside of 0. According to this method, a portion that does not have an area large enough to use the linear panel 220, for example, a floor in a toilet, or a portion used in combination with other heating appliances, for example, a floor portion of a kitchen, is used. It can be adopted in some way. And, naturally, the floor surface is heated by the lid body 260. Further, as a method of using the third embodiment, as shown in FIG. 11, a large number of sheets are arranged so that the periphery of the heat generating material 230 and the seamless pipe 240 are in contact with the thin plate-shaped fins 270 made of a material having good thermal conductivity. By providing the fins 270, the heat of the heat generating material 230 and the seamless pipe 240 is transferred to the entire fins 270, and the heat is easily transferred to the lid body 260, so that efficient floor heating can be performed. .

Next, a fourth embodiment will be described. This embodiment is as shown in FIGS. 12 and 13, in which the box body 310 and the lid body 360 are integrally molded. In this embodiment, the slits 380, 3 are formed on the lid 360.
90 is provided, and the inside of the hollow of the box 310 and the outside are connected by the slit portions 380 and 390. In some floor structures, the floor surface may be made of concrete, and the concrete for finishing can be filled in the box 310. Even in this case,
The through grooves 306, 307, 308 are provided. Here, as shown in FIG. 13A, all hollow portions of the box 310 are continuous, and when concrete flows in through the slit portions 380 and 390, the whole box 310 is spread. Thereby, the heat released from the heat generating material and the seamless pipe can be directly transmitted to the concrete. Also, FIG. 13 (b)
As shown in FIG.
The seamless pipe 340 is fixed by concrete.

It is needless to say that various embodiments can be adopted without departing from the spirit of the present invention. For example, in the above-mentioned embodiment, for convenience of explanation, only the one that uses the heat generating material and the seamless pipe at the same time has been described, but as described above, the heat generating material is a heating wire or the like, and the seamless pipe has hot water or the like therein. It circulates, both of which radiate heat under the floor, and either one may be used. Further, as shown in FIG. 14, when the box body 410 is made of synthetic resin foam, the side portions 401, 40 can be easily formed at the time of work without providing a through groove in advance.
By cutting 2, 403, the through groove can be provided only at an arbitrary position (necessary portion). Further, although the lid is adopted only in the third embodiment, it is possible to use the lid by providing the notch in the embedded panel shown in the first embodiment, and moreover, the notch. It is also possible to use it like a dropping lid without providing. Although such a lid is designed to supplement the transfer of heat from the heat generating material and the seamless pipe to the floor surface, the lid may be provided so as not to contact the heat generating material and the seamless pipe. In this case, it is possible to prevent the heat generating material and the seamless pipe from being damaged by nails and other obstacles that are driven from the floor surface.

Further, in each of the above-mentioned embodiments, the buried panel has a lot of space and the heat transfer from the heat generating material and the seamless pipe is poor, and moreover, the calorific value for floor heating can be obtained in the buried panel. Although it seems that the buried panel of the present invention is not possible, as shown in FIG.
When used with a linear panel, the embedded panel does not plan to generate heat, but only the linear panel is used for heating. As a result, the buried wavy heat generating material and the seamless pipe are heated only near the center. However, this does not mean that floor heating cannot be performed, and as shown in FIG. 3, it is not necessary to bury the heat generating material and the seamless pipe from corner to corner of room A, and it is sufficient if heat can be generated near the center of room A. is there.

However, when the heating element or the circulation pipe expands due to heating, the bending section can absorb the expansion section when the heating element or the circulation pipe expands due to heating. Alternatively, the service life of the circulation pipe can be extended and the failure rate of construction due to the deviation from the panel can be reduced.

According to the present invention, the heat generating material or the circulation pipe, which has passed through the through groove provided in the side plate, is arranged at random in the box body, and then the same or different through groove as the above through groove provided in the side plate.
