DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method of installing a so-called floor that preferably used for the heating system floor heating <br/> tufts panel to heat the room from floor.

[0002]

2. Description of the Related Art FIG. 8 is a perspective view showing a general installation state of a floor heating panel. Under the floor of a general house, a plurality of joists 32 are arranged so as to be parallel to each other at regular intervals to support the floor material 31, and a floor heating panel is provided between the joist 32 and the floor material 31. It is common to arrange 33.

[0003] By the way, the floor heating panel 33 is a small joist 3
4 and the heat insulating material 35 are arranged alternately, and a heat radiation sheet (not shown) is generally adhered to the upper surface (the surface on which the floor material 31 is disposed). Small joist 3
Numeral 4 is made of wood and arranged at substantially the same interval as joist 32. Then, the small joist 34 is placed on the joist 32 and the nail is driven into the floor heating panel 3.
3 is fixed. On the other hand, the heat insulating material 35 is made of small joists 34, 34.
A heat generator 36 is provided inside the heat insulating material 35. As the heating element, for example, a pipe through which warm water as a heat medium flows is used. Insulation material 3
For 5, foamed polystyrene or foamed polypropylene is used.

[0004] Between the floor heating panel 33 and the joist 32, a discarded plate 37 made of plywood is interposed.
This is provided to reinforce the heat insulating material 35 because the strength of the heat insulating material 35 is weaker than that of the small joist 34. Further, a heat insulating material 38 made of urethane or glass wool is disposed between the joists 32, 32 in order to prevent heat radiation to the lower side of the floor.

There are various structures for laying the pipe 36 in the floor heating panel 33. Two typical conventional examples will be described below. FIG. 9 is a schematic diagram showing a first conventional example. The first conventional example is disclosed in, for example, Japanese Utility Model Laid-Open No. 2-6780.
No. 8 discloses this. In the first conventional example, a groove 39 having substantially the same width and depth as the outer diameter of the pipe 36 is formed in the heat insulating material 35.
The pipe 36 is fitted into the groove 39, and the heat radiating sheet 40 is arranged and bonded so as to cover the surface on which the groove 39 is formed. As the heat dissipation sheet 40, an aluminum foil is used. In this structure, as shown in FIG. 9B, the upper surface of the pipe 36 comes into contact with the heat radiation sheet 40, and the heat from the pipe 36 is transmitted to the heat radiation sheet 40.

FIG. 10 is a schematic diagram showing a second conventional example. In the second conventional example, a groove 39 having the same width and depth as the outer diameter of the pipe 36 is formed in the heat insulating material 35, and the heat radiation sheet 4 is formed.
0 is bent in advance along the inner surface of the groove 39, and the processed heat dissipation sheet 40 is bonded to the heat insulating material 35,
The pipe 36 is fitted in the groove 39. In this structure, as shown in FIG. 10B, the pipe 36 and the heat radiation sheet 40 come into contact with each other along the inner surface of the groove 39, and the heat from the pipe 36 is transmitted to the heat radiation sheet 40.

[0007]

In the first prior art, the number of manufacturing steps is relatively small, ie, three steps of forming the groove 39, fitting the pipe 36, and bonding the heat radiation sheet 40. Is also relatively simple and can be easily manufactured. However, as shown in FIG. 9B, since the heat radiation sheet 40 contacts only a small area on the upper surface of the pipe 36,
(A direction perpendicular to the longitudinal direction of the slab) is small. Therefore, the surface temperature of the heat radiation sheet 40 becomes uneven, the peaks and valleys of the temperature distribution become large, and the uniformity of the temperature distribution becomes poor. A groove 39 is provided below the pipe 36.
Because the heat insulating material 35 below the pipe 36 is thin, the amount of heat radiation in the downward direction increases, and the thermal efficiency deteriorates.

In the second conventional example, since the heat radiation sheet 40 is in contact with the lower side of the pipe 36 in a region corresponding to about half of the outer periphery thereof, the amount of heat transfer in the lateral direction is large, and There is an advantage that the amount of heat radiation is small, the uniformity of the temperature distribution and the thermal efficiency are good. However, the number of manufacturing steps is four, that is, the formation of the groove 39, the bending of the heat radiation sheet 40, the adhesion of the heat radiation sheet 40 to the heat insulating material 35, and the fitting of the pipe 36.
The manufacturing cost increases as compared with the conventional example. In addition, since bending of the heat radiation sheet 40 requires the use of a dedicated jig or equipment, the operation is complicated and time-consuming. Further, the heat dissipation sheet 40 needs to have a certain strength so as not to be broken when it is bent, and it is necessary to make the heat dissipation sheet 40 thick to secure the strength. This also increases the manufacturing cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide a floor heating panel base capable of realizing a sufficient contact state between a pipe and a heat radiation sheet simply by inserting the pipe. with wood, it is to provide a method of installing floor heating panel that can <br/> in be installed floor heating panel having excellent uniformity of the temperature distribution in a simple operation.

[0010]

According to a first aspect of the present invention , there is provided a method of installing a floor heating panel , wherein a heat insulating material having a groove for receiving a heat medium circulating pipe is formed so as to cover the groove. A heat-dissipating sheet 4 is provided. The heat-dissipating sheet 4 has a breakable portion 7 having a weaker breaking strength than its periphery, such as a perforation, at a position corresponding to a substantially central portion of the groove 5 in the width direction. by forming along the groove 5

As a result, it is pushed into the inside of the groove 5 and comes into contact with the outer peripheral surface of the heat medium circulation pipe 6. Therefore, heat from the heat medium circulation pipe 6 is easily transmitted to the heat radiating sheet 4 located in the vicinity of the groove 5, the uniformity of the temperature distribution is improved, and good floor heating can be realized. Further, since two operations of fitting the heat medium circulating pipe 6 into the groove 5 and contacting the heat medium circulating pipe 6 with the heat radiating sheet 4 can be performed at the same time, the installation work is simplified. Furthermore, since the plurality of floor heating panel base materials 1 are arranged, a relatively long heat medium circulation pipe 6 can be fitted into the groove 5 over the plurality of base materials 1. The number of joints between the joints can be reduced, and leakage of the heat medium from the joints can be reduced. In addition, since the base material 1 in which the heat medium circulation pipe 6 is not fitted is relatively light, the burden on the operator in carrying out work and installation work is reduced.

It is characterized by that.

According to the floor heating panel installation method of the second aspect, the heat released from the heat medium circulation pipe 6 toward the bottom of the groove 5 is arranged along the inner surface of the groove 5. The heat conduction sheet 15 is transmitted to the heat dissipation sheet 4. for that reason,
The heat utilization efficiency is improved, and the uniformity of the temperature distribution of the heat radiation sheet 4 is also improved.

According to a third aspect of the present invention , the heat conductive sheet 13 having a width larger than the width of the groove 5 is brought into contact with the upper surface of the heat medium circulation pipe 6 and the heat radiation sheet 4 therearound. It is characterized by being arranged.

According to the floor heating panel installation method of the third aspect , part of the heat emitted upward from the heat medium circulation pipe 6 is also transmitted to the heat radiation sheet 4.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next , the installation of the floor heating panel of the present invention will be described.
Specific embodiments of the placement method will be described in detail with reference to the drawings. 1 embodiment smell of one embodiment of the present invention
Floor heating panel substrate using Te (hereinafter, sometimes simply referred to as "substrate") indicates a 1, (a) is a perspective view,
(B) is a cross-sectional view showing a part enlarged. Since the installation state of the base material and the floor heating panel is the same as that of the conventional example, it will be described with reference to FIG.

The substrate 1 has a flat plate shape, in which small joists 2 and heat insulating materials 3 are alternately arranged.
The heat radiation sheet 4 is adhered to almost the entire surface of the floor material 31 shown in FIG. The small joists 2 are used to ensure strength, are made of, for example, wood, have substantially the same width as the joists 32 (see FIG. 8), and are arranged at the same intervals as the joists 32. Therefore, the small joist 2 is discarded and the plate 37
And the nails are driven from the small joists 2 toward the joists 32 to interpose the base material 1.
Can be fixed.

On the other hand, the heat insulating material 3 is formed of expanded polystyrene, expanded polypropylene, or the like, is interposed between the small joists 2 and 2, and has a groove 5 formed on the upper surface thereof. The groove 5 is for fitting a heat medium circulating pipe (hereinafter simply referred to as “pipe”) 6 which is a heating element.
The heat insulating material 3 is formed in a straight line from one end face to the opposite end face in parallel with the longitudinal direction. The bottom surface of the groove 5 is formed in a semicircular shape having a radius substantially equal to the radius of the cylindrical pipe 6, the side surface is formed substantially perpendicular to the upper surface, and the width W and the depth H of the groove 5 are formed. Is selected to be approximately the same length as the outer diameter of the pipe 6. Therefore, when the pipe 6 is fitted into the groove 5,
About half of the outer circumference of the pipe 6 contacts the bottom surface,
Is located at substantially the same position as the upper surface of the heat insulating material 3.

The number of grooves 5 formed in one heat insulating material 3 is not limited to two as shown in FIG. 1A, but may be one or three or more. . Also,
The groove is not limited to a straight groove, and may be a curved groove if the pipe 6 can be bent.

The heat radiating sheet 4 is formed of a material having relatively good thermal conductivity, for example, aluminum foil, and its thickness is selected to be, for example, 50 μm. The heat radiation sheet 4 is adhered to almost the entire surface so as to cover the upper surface of the heat insulating material 3 (the surface having the groove 5) and the upper surface of the small joist 2. The heat radiating sheet 4 has a perforation 7 which is a breakable portion (shown by a dashed line in FIG. 1 (a)) over a substantially entire length along the groove 5 at a position corresponding to a substantially central portion of the groove 5 in the width direction. ) Is formed. The heat radiation sheet 4 is provided with a groove 5
It is not necessary to dispose it on the entire surface, as long as it covers the periphery of the small joist 2.

A perforation is generally made by forming a plurality of relatively small holes at intervals to cut a sheet.
It is formed in a row, and when a certain force is applied, a connection portion between the holes is broken and can be cut into two. The shape of the holes is preferably a long hole extending in the longitudinal direction of the groove 5, and the arrangement pattern of the holes is preferably a periodic one such as a broken line or a dashed line.

FIG. 2 is a schematic view showing an example of a method for forming perforations 7. In the bonding step of the heat radiating sheet 4, a roll body 9 in which an aluminum foil is wound in a roll shape on the surface of a plate body 8 formed by alternately arranging the heat insulating materials 3 in which the grooves 5 are formed and the small joists 2. While disassembling, the plate-like body 8 is conveyed and the aluminum foil (heat dissipation sheet 4) is adhered. At this time, the cutter 10 is arranged at a position corresponding to the central portion of the groove 5, and the cutter 10 is moved up and down in synchronization with the transport speed of the plate-like body 8, thereby sequentially forming long holes extending in the longitudinal direction of the groove 5. To form perforations 7.

FIG. 3 is a cross-sectional view showing a process of fitting the pipe 6 into the base material 1. As shown in FIG. 3A, the pipe 6 arranged along the perforation 7 of the heat radiation sheet 4 is
, The heat radiation sheet 4 is broken at the perforation 7. Further, as shown in FIG. 3B, by pushing the pipe 6 into the groove 5 as it is, the portion near the broken portion of the heat radiation sheet 4 after the break is pushed into the inside of the groove 5 by the pipe 6. And
As shown in FIG. 3 (c), when the pipe 6 is pushed in until it comes into contact with the bottom surface of the groove 5 and is completely fitted, the portion in the vicinity of the fractured portion extends along the side surface of the groove 5 and the outer periphery of the pipe 6. It is arranged up to a length A of about half of the outer diameter. Thus, the floor heating panel 11 is completed. In this floor heating panel 11, the portions near the two broken portions of the heat radiation sheet 4 are in contact with the outer periphery of the pipe 6 in the grooves 5, respectively.
, Heat is easily transmitted to the heat dissipation sheet 4 located around the groove 5, the uniformity of the temperature distribution is improved, and good floor heating can be realized.

The step of inserting the pipe 6 into the base material 1 may be performed at a factory or at a site where the floor heating panel 11 is installed. That is, the base material 1 and the pipe 6 may be shipped separately, or the floor heating panel 11 into which the pipe 6 is inserted may be shipped.

When installing the floor heating panel 11 as a finished product, as shown in FIG. 8, a plurality of floor heating panels 11 are arranged and fixed on a discard plate 37 arranged on a joist 32. Then, the floor material 31 may be disposed thereon. However, when installing a floor heating panel, a plurality of floor heating panels 1
It is necessary to connect the pipes 6 of the floor heating panels 11 after the arrangement of the pipes 1 to form a circulation path, and to connect to a hot water supply source. For this reason, the number of joints between the pipes 6 increases, and the connection work is troublesome. In addition, if the connection is incomplete, there is a risk that hot water may leak from the seam portion, and if the number of seams is large, there is a disadvantage that hot water leakage is more likely to occur.

If the size of the floor heating panel 11 is increased in order to solve this drawback, the number of seams of the pipe 6 can be reduced, but the weight becomes heavy and it is inconvenient to transport, and the size is small. There is a limit. Therefore, at present, a plurality of floor heating panels 11 each of which folds about one tatami mat are used.

On the other hand, when the floor heating panel 11 is installed using the base material 1, as shown in FIG. 8, a plurality of base materials 1 are placed on the discard plate 37 placed on the joist 32. And the pipe 6 is fitted into each base material 1 so that the floor heating panel 1
1 and then the floor material 31 may be arranged thereon. At this time, if a relatively long pipe 6 is used, one pipe 6 can be fitted over a plurality of base materials 1 and the number of joints between the pipes 6 can be reduced as much as possible. Thereby, the number of operations for connecting the pipes 6 is reduced, the connection can be reliably performed, and the leakage of hot water from the joint is less likely to occur.

Further, the size of the minimum unit of the base material 1 can be reduced, and it is possible to flexibly correspond to rooms of various sizes. Furthermore, the base material 1 in which the pipe 6 is not inserted is relatively light, and the burden on the operator in the transporting work and the installation work is reduced.

Further, the pipe 6 can be inserted by simply pushing the pipe 6 into the groove 5 without using a special jig as described with reference to FIG. At the same time, a good contact state between the pipe 6 and the heat radiation sheet 4 is realized (see FIG. 3C).
There is no extra burden on the operator during the fitting operation.

[0030] Figure 4, use in other embodiments of the present invention
It is sectional drawing which expands and shows a part of floor heating panel 12 which is. The floor heating panel 12 is configured by further bonding a heat conductive sheet 13 to the floor heating panel 11 shown in FIG. The heat conductive sheet 13 is formed of a material having good heat conductivity, for example, aluminum foil, and has a width larger than the width of the groove 5. The heat conductive sheet 13 is adhered to the upper surface of the pipe 6 and the heat radiating sheet 4 around the groove 5.

In the floor heating panel 12, part of the heat released upward from the pipe 6 is also transmitted to the heat dissipation sheet 4 via the heat conduction sheet 13. Therefore, the uniformity of the temperature distribution of the heat radiation sheet 4 is further improved as compared with the floor heating panel 11. Thereby, good floor heating can be realized.

[0032] Figure 5 is a further embodiment of the present invention
It is sectional drawing which shows the structure of the base material 14 for floor heating panels used in it. As shown in FIG. 5 (a), the heat conductive sheet 15 is arranged on the base material 14 in advance along the inner surface of the groove 5 formed in the heat insulating material 3, and the surface is shown in FIG. 5 (b). The heat radiation sheet 4 is bonded as described above.

The heat conductive sheet 15 may be formed of a material having good heat conductivity, for example, an aluminum foil, and may be a sheet having a width that can be along the inner surface of the groove 5. As compared with the case where a part of a large sheet is bent as in the conventional example, strength is not so much required and a thin sheet can be used. For example, it may be about 50 μm, which is the same as the heat radiation sheet 4. Therefore, it can be manufactured at low cost.

FIG. 6 is a cross-sectional view showing a step of fitting the pipe 6 into the base material 14. As shown in FIG. 6A, when the pipe 6 arranged along the perforation 7 of the heat radiation sheet 4 is pressed toward the groove 5, the heat radiation sheet 4 is broken at the perforation 7. Further, by pushing the pipe 6 into the groove 5 as it is, the portion near the broken portion of the heat radiation sheet 4 after the break is pushed into the inside of the groove 5 by the pipe 6. Then, as shown in FIG.
When the pipe 6 is pushed in until it comes into contact with the bottom surface of the groove 5 and is completely fitted, the portion near the broken portion extends along the heat conduction sheet 15 on the side surface of the groove 5 and the outer periphery of the pipe 6 to about half of the outer diameter of the pipe 6. It is arranged up to the part. Thus, the floor heating panel 16 is completed.

In the floor heating panel 16, the heat radiation sheet 4
Are in contact with the outer periphery of the pipe 6 in the groove 5 and also contact the heat conductive sheet 15 previously arranged in the groove 5. Therefore, the heat from the pipe 6 is directly transmitted to the heat dissipation sheet 4 and the lower side of the pipe 6,
That is, the heat released to the bottom side of the groove 5 is also transmitted to the heat dissipation sheet 4 via the heat conduction sheet 15. Thereby, compared with the floor heating panel 11, the uniformity of the temperature distribution is improved, and excellent floor heating can be performed.

Further, by disposing the heat conductive sheet 15 in the groove 5, even if the length from the bottom surface of the groove 5 to the back surface of the heat insulating material 3 is shortened, the heat released to the bottom surface side of the groove 5 can be reduced. Can be used effectively. Therefore, the thickness of the heat insulating material 3 can be reduced, and the thickness of the floor heating panel 16 (base material 14) can be reduced.

[0037] Figure 7 is a further embodiment of the present invention
It is sectional drawing which shows the structure of the floor heating panel 17 used in it. The floor heating panel 17 is configured by further bonding the heat conductive sheet 13 to the floor heating panel 16 shown in FIG. The heat conductive sheet 13 is the same as that used in the floor heating panel 12 shown in FIG. 4 and performs the same function. Therefore, the floor heating panel 17 is the floor heating panel 1.
6, the uniformity of the temperature distribution of the heat radiation sheet 4 is further improved. Thereby, good floor heating can be realized.

[0038]

As described above, the floor heating panel according to claim 1 can be used .
According to the installation method , the heat from the heat medium circulation pipe is easily transmitted to the heat radiation sheet located around the groove, the uniformity of the temperature distribution is improved, and good floor heating can be realized. Moreover, the pipe for heating medium circulation just by fitting into the groove, is possible to contact the heat radiation sheet and heat circulation pipe simultaneously
Since it, installation work is simplified. Further, by fitting one relatively long pipe into the groove over a plurality of base materials, the number of seams between the pipes can be reduced, and the leakage of the heat medium from the seams can be reduced. . Further, since the base material in which the heat medium circulation pipe is not fitted is relatively lightweight, the burden on the operator in carrying out work, installation work and the like is reduced.

According to the floor heating panel installation method of the second aspect, the heat released from the heat medium circulation pipe toward the bottom of the groove is also transmitted to the heat radiating sheet, so that the heat utilization efficiency is improved. At the same time, the uniformity of the temperature distribution of the heat dissipation sheet is improved. Further, since the heat insulating material on the lower side from the bottom of the groove can be made thin, the floor heating panel can be made thin.

According to the floor heating panel installation method of the third aspect , part of the heat emitted upward from the heat medium circulation pipe is also transmitted to the heat radiating sheet, so that the temperature distribution of the heat radiating sheet is uniform. The performance is further improved.
