BACKGROUND OF THE INVENTION
The present invention relates to a heating mat that is disposed on an indoor wall, ceiling, flooring floor, or the like to heat an indoor room.
[0002]
[Prior art]
As a device for floor heating such as flooring, a hot water heating mat is known. FIG. 12 (a) shows an example of a heating mat developed by the present applicant together with a heat source, and FIG. 12 (b) shows a cross-sectional configuration example of the heating mat shown in FIG. 12 (a). Is indicated by a solid line. As shown in FIGS. 12A and 12B, the heating mat 1 has a mat body 2 which is a plate-like mat portion. The mat body 2 has a small joist 3 which is a joist and a small mat base. It has a material 4 and small and small joists 5 that are joists. The small joist 3 and the small joist 5 form a pair and are arranged almost coaxially through a gap to form a joist. The joist and the small mat base 4 are alternately arranged to form the mat body 2. Is configured.
[0003]
One or more pipes 6 for passing warm water, which is a heating medium for heating, are provided in the gap between the small joists 3 and small joists 5 in the mat body 2 and the upper surface side of the small mat base 4 (see FIG. 12). In the example shown in (a), two pipes 6a and 6b are routed.
[0004]
A header member 7 is incorporated in the mat body 2. This header member 7 connects the pipe 6 to the heat source device 10 through the external pipe 8 and is supplied from the heat source device 10 through the external pipe 8 in the example shown in FIG. The function is to supply the hot water flowing out from the pipe 6a and the hot water flowing out from the pipe 6b to join the hot water flowing out from the pipe 6a and return to the heat source device 10 through the external pipe 8. Is.
[0005]
The small mat base material 4 is made of, for example, a foamed resin material such as polystyrene having an expansion ratio of about 20 times. On the upper surface of the small mat base material 4, as shown in FIG. A pipe groove 11 for accommodating and arranging the pipe 6 is formed. After the pipe 6 is accommodated in the pipe groove 11, an aluminum foil 12 as a heat radiating material is applied to the upper surface of the mat body 2 using an adhesive or the like so as to cover the entire upper surface of the mat body 2. It is pasted.
[0006]
By the way, as shown in FIG. 13, the heating mat 1 (mat body 2) may be wound and packaged so that the upper surface (the surface on which the aluminum foil 12 is attached) is inside. In order to make it easy to wind up the heating mat 1 during the packaging, the applicant of the present invention is substantially perpendicular to the winding direction on the outer surface when the heating mat 1 is wound up, that is, on the bottom surface of the mat body 2. It has been proposed that a plurality of grooves 18 as shown in FIG. 12B and the dotted line in FIG.
[0007]
In the example shown in FIG. 13, the heating mat 1 is wound and packed in a direction substantially perpendicular to the small joists 3, and thus the groove 18 is a bottom surface that becomes the outer side when the heating mat 1 is wound. The mat body 2 is formed so as to extend from one end side to the other end side in a direction substantially parallel to the small joists 3. For example, when the thickness D of the mat body 2 is 12 mm, the groove The depth d of 18 is formed to be about 9 mm.
[0008]
The heating mat 1 shown in FIGS. 12 (a) and 12 (b) is configured as described above, and the heating mat 1 is placed on the floor panel 14 as shown by the dotted line in FIG. 12 (b). The flooring 15 is laid on the upper side of the heating mat 1. The flooring 15 is provided with a region where nails 16 are struck. When the heating mat 1 or the flooring 15 is laid, a predetermined nailing region of the flooring 15 and the heating mat 1 are small. The heating mat 1 and the flooring material 15 are laid so that the joists 3 and the small joists 5 are aligned, and then a nail 16 is struck in the nailing area of the flooring material 15, The flooring 15 and the heating mat 1 are fixed by punching out the small joist 3 and the small joist 5 on the lower side.
[0009]
In the heating mat 1 laid in this way, the hot water produced by the heat source device 10 flows into the pipes 6a and 6b through the external pipe 8 and the header member 7 in order, and the hot water flows through the pipes 6a and 6b. The heat of the hot water is radiated into the room, and the room is heated. Then, the hot water flowing through the pipes 6a and 6b is returned to the heat source device 10 through the header member 7 and the external pipe 8, heated again by the heat source device 10, and supplied to the heating mat 1 through the external pipe 8 as described above. The Thus, the heating mat 1 heats the room by flowing the hot water of the heat source device 10 through the pipe 6 disposed in the mat body 2.
[0010]
[Problems to be solved by the invention]
FIG. 14A is a schematic perspective view showing the arrangement region of the header member 7 extracted. As shown in this figure, the small mat base 4 is formed with a notch 20 as a header accommodating portion, and the header member 7 is accommodated in the notch 20. Thus, the opening on the mat body upper surface side of the notch 20 accommodating the header member 7 is closed by the aluminum foil 12.
[0011]
By the way, as mentioned above, the heating mat 1 may be wound and packed with the aluminum foil 12 inside as shown in FIG. Since the header member 7 is formed of a material that is difficult to bend and deform, the header member 7 may be bent and deformed along with the bending deformation of the mat body 2 (small mat base material 4) during the above-described winding packaging. 14B, the header member 7 floats up from the notch 20 while pushing up the aluminum foil 12, and the pipe 6 connected to the header member 7 as the header member 7 lifts up. The header member connecting end portion of the header member pushes up the aluminum foil 12 and lifts the aluminum foil 12 from the small mat base material 4 and floats up from the pipe groove 11.
[0012]
Thus, when the heating mat 1 is wound and packed, if the header member connecting end portion of the pipe 6 is lifted from the pipe groove 11 while peeling the aluminum foil 12 from the small mat base material 4, When the heating mat 1 is laid out and laid, the pipe 6 may not properly enter the pipe groove 11 and ride on the upper surface of the small mat substrate 4 in some cases. In this way, if the flooring material 15 is laid on the upper side of the heating mat 1 while the pipe 6 rides on the upper surface of the small mat base material 4, the pipe rides on the upper surface of the mat base material 4. 6 causes a gap between the heating mat 1 and the flooring 15, and this gap causes a problem of uneven heating temperature, and when the person walks on the flooring 15, the flooring 15 The problem of the squealing floor, the floor subsidence of the flooring material 15 sinking and giving a fluffy discomfort, and the like occur.
[0013]
Further, for example, even when the U-turn part 35 as shown in FIG. 12A is provided on the routing path of the pipe groove 11 (pipe 6), the heating mat 1 is provided in the U-turn part 35. There is a possibility that the same problem as that in the area where the header member 7 is disposed may occur when winding and packing. That is, since the U-turn portion of the pipe 6 is difficult to bend and deform along with the bending deformation of the mat body 2, when the heating mat 1 is wound and packed, the U-turn portion of the pipe 6 is bent and deformed by the mat body 2. Accordingly, the aluminum foil 12 is pushed up and lifted from the pipe groove 11 while being peeled off from the small mat base material 4.
[0014]
As described above, when the pipe 6 is lifted from the pipe groove 11, when the heating mat 1 is spread and laid, the pipe 6 does not enter the pipe groove 11, and the pipe 6 is the small mat base material 4. If the flooring material 15 is laid on the upper side of the heating mat 1 in this state, the problem of uneven temperature of the heating, the problem of ringing of the floor, the problem of sinking of the floor, etc. Occurs.
[0015]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below with reference to the drawings.
[0028]
FIG. 1A schematically shows an arrangement region of a header member that is characteristic in the first embodiment. In the description of the first embodiment, the same components as those in the heating mat shown in FIGS. 12 (a) and 12 (b) are denoted by the same reference numerals, and overlapping description of the common portions is omitted.
[0029]
What is characteristic in the first embodiment is that the notch 22 is formed as shown in FIG. Other configurations are the same as those of the heating mat 1 shown in FIGS. 12 (a) and 12 (b).
[0030]
The notch 22 is used as a lifting prevention means, and when the mat body 2 as the mat portion is bent with the aluminum foil 12 as the heat radiating material inside as when the heating mat 1 is wound and packed. The header member 7 can be prevented from floating from the notch 20 which is the header accommodating portion. In the first embodiment, the notch 22 is formed on the extension line of the rear end surface 20a of the notch 20 from the notch 20 toward the left and right sides shown in FIG. It penetrates from the foil 12 to the bottom surface of the small mat substrate 4. The cut direction of the cut 22 is substantially the same as the bending direction of the mat body 2 (that is, the direction substantially perpendicular to the small joists 3 and the grooves 18).
[0031]
FIG. 1B is a schematic cross-sectional view of the AA portion shown in FIG. 1A when the heating mat of the first embodiment is bent so that the aluminum foil 12 is inside. It is shown. In the first embodiment, the notches 22 are formed as described above. Therefore, when the mat body 2 is bent with the aluminum foil 12 inside, as shown in FIG. In addition, it is possible to make the arrangement region of the header member 7 independent of the bending deformation of the mat body 2 and to suppress the header member 7 from being lifted from the notch 20.
[0032]
Thus, when the mat body 2 is bent with the aluminum foil 12 inside, the header member 7 can be prevented from floating from the notch 20, so that the header member connecting end of the pipe 6 is connected to the pipe groove. Therefore, the problem caused by the rising of the pipe 6 from the pipe groove 11, that is, the problem of the temperature unevenness of the heating, the problem of the floor squealing, the problem of the sinking of the floor, and the like can be suppressed. It is possible to prevent the occurrence of problems such as the dropout of the small joist 5.
[0033]
By the way, in the first embodiment, as described above, the notch 22 is provided so that the arrangement area of the header member 7 is independent from the bending deformation of the mat body 2, so that the aluminum foil 12 is disposed inside. When the mat body 2 is bent, the small mat substrates 4 (4a, 4b) disposed on the left and right sides of the notch 20 approach the header member 7 (the α and β directions shown in FIG. 1B). ).
[0034]
In such a case, the straight portion of the pipe 6 that is linearly arranged along the bending direction of the mat body 2 from the header member 7 to the pipe groove 11 from the header member 7 in FIG. ), The pipe 6 is slackened at the bent portion 23, and the slack portion of the pipe 6 is lifted from the pipe groove 11. There is a risk of problems occurring due to the lifting of the pipe 6 from the pipe groove 11.
[0035]
For this reason, in the first embodiment, the following measures are taken in order to prevent the occurrence of the problem due to the pipe 6 being lifted due to the displacement movement of the pipe 6. That is, in the first embodiment, the bent portion of the pipe groove 11 (that is, the portion whose path is changed in a direction substantially orthogonal to the straight portion in the bending direction of the mat body 2) 23a, 23b, 23c, 23d As shown in FIG. 2, one or more of these are formed wide.
[0036]
The wide bent portion 23 has a width H that allows the pipe 6 to move when the pipe 6 is displaced and the pipe 6 is slackened as shown by a chain line in FIG. The pipe groove width H is approximately twice the thickness of the pipe 6.
[0037]
As described above, when one or more of the bent portions 23a, 23b, 23c, and 23d are formed to have a wide width that allows the pipe 6 to be displaced, the pipe 6 is bent when the mat body 2 is bent. Even if the pipe 6 is loosened due to slippage, the slack portion of the pipe 6 is accommodated in the wide bent portion 23 of the pipe 6, and the slack portion of the pipe 6 is prevented from floating from the pipe groove 11. It is possible to avoid the above-mentioned problem caused by the rising of the pipe 6 from the pipe groove 11.
[0038]
By the way, as described above, when the wide bent portion 23 is formed, the wide bent portion 23 may not be housed stably and may be played. Therefore, in the first embodiment, the wide bent portion 23 is provided with the following pipe support member. The pipe support member is formed between the pipe 6 accommodated in the bent portion 23 and the side wall surface of the pipe groove 11 to absorb and support the displacement movement of the pipe 6.

In the first embodiment, one or more of the bent portions 23a, 23b, 23c, and 23d in the pipe groove 11 are not moved. Since the pipe 6 is formed wide enough to allow the slack of the pipe 6, the slack portion of the pipe 6 can be prevented from floating from the pipe groove 11, and problems caused by the pipe 6 being lifted can be prevented. it can.
[0054]
Furthermore, since warm water flows through the pipe 6, the pipe 6 may thermally expand due to the heat of the warm water, and the pipe 6 may slack. In the first embodiment, as described above, the pipe groove 11 Since the wide bent portion 23 is provided, even when the pipe 6 is slackened due to thermal expansion, the slack portion of the pipe 6 is absorbed and accommodated in the wide bent portion 23 and the pipe 6 is lifted from the pipe groove 11. It is possible to prevent the occurrence of problems caused by the above-described lifting of the pipe 6.
[0055]
Furthermore, as described above, when the bent portion 23 is formed wide, there is a possibility that the pipe 6 may play with the wide bent portion 23. However, in the first embodiment, the wide portion Since the pipe support member is provided in the bending part 23, the play of the pipe 6 can be prevented by the pipe support member.
[0056]
Furthermore, in the case where the pipe support member is provided, when there is a possibility that the pipe 6 rides on the pipe support member and the pipe 6 protrudes from the pipe groove 11, the first embodiment is used. In the example, since the protrusion preventing means for avoiding the problem is provided, the protrusion problem of the pipe 6 can be surely prevented.
[0057]
The second embodiment will be described below. In the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the duplicate description of the common portions is omitted.

The cut 32 formed in the small joist 3 is an extension of the cut 22 formed in the small mat base 4, is formed along the bending direction of the mat body 2, and is formed from the aluminum foil 12 with the small joist 3. It penetrates to the bottom. The cut 32 may be formed over the entire length of the small joist 3 in the width direction, or may be up to the middle of the small joist 3 in the width direction. The header member 7 has an appropriate length that can prevent the header member 7 from being lifted.
[0061]
As shown in FIG. 6, when the pipe 6 is disposed across the small joist 3, a groove (not shown) for accommodating the pipe 6 is formed in the small joist 3.
[0062]
In the second embodiment, when the small joist 3 is formed in the vicinity of the region where the header member 7 is disposed, the notch 32 is formed in the small joist 3 as well. Even when the small joists 3 are arranged in the vicinity of the region, when the mat body 2 is bent, the header member 7 can be reliably prevented from being lifted from the notch 20. It is possible to reliably avoid the occurrence of problems caused by floating.
[0063]
The third embodiment will be described below. In the description of the third embodiment, the same reference numerals are given to the same components as those in each of the above embodiments, and the overlapping description of the common portions is omitted.
[0064]
The third embodiment is different from the above embodiments in that the header member 7 is formed in the opening on the bottom surface of the mat body of the notch 20 as shown in FIGS. That is, an insulating sheet 34 which is an insulating member covering the surface is formed. Other configurations are the same as those in the above-described embodiments.
[0065]
The insulating sheet 34 is made of, for example, an insulating material such as plastic or nylon. For example, the insulating sheet 34 is affixed to an opening edge of the notch 20 on the bottom surface side of the mat body with an adhesive or an adhesive tape to cover the header member 7. ing.
[0066]
In the third embodiment, as described above, the insulating sheet 34 is attached to the opening end edge of the notch 20 on the mat body bottom surface side. When the mat body 2 is bent with the aluminum foil 12 on the inside, when the area where the header member 7 is arranged is bent together with the bending deformation of the mat body 2 as in the prior art, a large tensile force is applied to the insulating sheet 34. There is a problem that the insulating sheet 34 is peeled off due to the action.
[0067]
On the other hand, in the third embodiment, as described above, since the arrangement area of the header member 7 is independent from the bending deformation of the mat body 2, the mat is provided with the aluminum foil 12 inside. When the main body 2 is bent, it is possible to suppress a large pulling force from acting on the insulating sheet 34 and to prevent the insulating sheet 34 from peeling off.

Further, in the third embodiment, in addition to the configuration of each of the above embodiments, an insulating sheet 34 covering the bottom surface side of the header member 7 is provided in the opening on the mat body bottom surface side of the notch 20. Since it is arranged, a nailing test as shown below can be performed accurately when the heating mat 1 is laid.
[0069]
The nail driving inspection is an inspection for checking whether or not the nail 16 has punched the pipe 6 by mistake. When the flooring material 15 is laid on the upper side of the heating mat 1, the nail 16 may accidentally punch out the pipe 6 of the heating mat 1, and in this case, the pipe into which the nail 16 has been driven. Water leaks from the part, which becomes a serious problem. Therefore, the nail driving inspection is performed.
[0070]
The nail inspection is performed by checking whether or not the aluminum foil 12 and the header member 7 can be energized with water in the pipe 6. This is because when the header member 7 is made of a conductive material, the header member 7 is in a state where it can be energized with the water in the pipe 6. When the nail 16 has punched the pipe 6, the water in the pipe 6 can be energized with the aluminum foil 12 through the nail 16. In this case, the header member 7 and the aluminum foil 12 are electrically connected. By doing so, an energization path composed of the header member 7, the water in the pipe 6, the nail 16 and the aluminum foil 12 is formed. On the other hand, when the nail 16 has not punched the pipe 6, the water in the pipe 6 and the aluminum foil 12 are insulative, so even if the header member 7 and the aluminum foil 12 are electrically connected, the header An energization path passing through the member 7 and the water in the pipe 6 and the aluminum foil 12 is not formed.
[0071]
From this, it is possible to inspect whether or not the nail 16 has punched the pipe 6 by examining whether or not the header member 7 and the aluminum foil 12 are energized using a very sensitive tester. That is, when the header member 7 and the aluminum foil 12 are energized, it is determined that the nail 16 has punched the pipe 6, and when the header member 7 and the aluminum foil 12 are not energized, the nail 16 Judged not punched.
[0072]
However, when the heating mat 1 is laid on the upper side of the floor panel 14 and the upper surface of the floor panel 14 is wet, the header member 7 and the water on the floor panel 14 are in a state where electricity can be passed, and Since the water on the floor panel 14 can be energized with the aluminum foil 12 via the nail 16, an energization path composed of the header member 7, the water on the floor panel 14, the nail 16 and the aluminum foil 12 is formed. Therefore, regardless of whether or not the nail 16 is driven into the pipe 6, the header member 7 and the aluminum foil 12 become energized and there is a problem that an accurate result of the nail driving inspection cannot be obtained. Arise.
[0073]
In the third embodiment, the insulating sheet 34 covering the header member 7 is formed in the opening on the bottom surface side of the mat body of the notch 20 as described above, so that the upper surface of the floor panel 14 and the header member 7 are insulated. Even if the floor panel 14 is wet, the energizing path composed of the header member 7, the water on the floor panel 14, the nail 16 and the aluminum foil 12 is not formed. Accurate nailing inspection results can be obtained.

[0093]
Furthermore, according to the present invention, The floating prevention means is formed by cutting along the bending direction of the mat portion penetrating from the heat dissipation material to the bottom surface of the mat portion. Because The header member and the pipe groove U-turn part formation area are made independent of the bending deformation of the mat part, and the header member and the pipe are prevented from being lifted with a simple configuration in which the notch is simply formed in the mat part. This can prevent problems caused by the lifting of the pipe.
[0094]
In the case where the joist is arranged in the formation area of the lifting restraining means in the mat portion and the notch which is the lifting restraining means is also formed in the joist, the joist is formed in the formation area of the lifting restraining means. Even in such a case, the same effect as described above can be obtained.
[0095]
One or more of the bent portions in the pipe groove are formed so that the pipe groove width is wide enough to allow the displacement movement of the pipe, and the wide bending portion is provided with a pipe support member that absorbs and supports the displacement movement of the pipe. In that case, for example, when the mat portion is bent, when the pipe is displaced in the direction from the straight portion in the bending direction of the mat portion toward the bent portion and the pipe is slackened at the bent portion, The wide bent portion can absorb the slack of the pipe, can suppress the slack portion of the pipe from floating from the pipe groove, and can prevent the above-described problems caused by the pipe floating. In addition, since the pipe support member is provided in the wide bent portion as described above, it is possible to prevent the pipe from playing in the wide bent portion.
[0096]
If the pipe support member is an integral part of the pipe wall in which the groove wall of the pipe groove protrudes and deforms, the pipe support member is formed at the same time as the pipe groove is formed. Can be suppressed.
[0097]
