FIG. 1A schematically shows a region where the header member is provided, which is characteristic in the first embodiment. In the description of the first embodiment, the same components as those of the heating mat shown in FIGS. 12A and 12B are denoted by the same reference numerals, and the description of the common portions will be omitted.

A characteristic feature of the first embodiment is that the cut 22 is formed as shown in FIG. Other configurations are the same as those of the heating mat 1 shown in FIGS. 12A and 12B.

The notch 22 serves as a means for suppressing lifting, and the mat body 2 as a mat portion is bent with the aluminum foil 12 as a heat dissipating material inside as in the case of winding and packing the heating mat 1. When the header member 7
Can be suppressed from floating out of the notch 20 which is the header accommodating portion. In the first embodiment, the notch 22 is formed by cutting the notch 20 from the notch 20 toward the left and right sides as shown in FIG. It penetrates from the foil 12 to the bottom surface of the small mat substrate 4. The cutting direction of the cut 22 is substantially the same as the bending direction of the mat body 2 (that is, the direction substantially orthogonal to the small joist 3 and the groove 18).

FIG. 1B shows a cross section taken along the line AA of FIG. 1A when the heating mat of the first embodiment is bent so that the aluminum foil 12 is on the inside. A schematic diagram is shown. In the first embodiment, since the cuts 22 are formed as described above, the aluminum foil 1

As described above, 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.
It is also possible to suppress the header member connection end of the pipe 6 from rising out of the pipe groove 11, and, as a result,
The problems caused by the lifting of the pipe 6 from the pipe groove 11, that is, the problems of the uneven heating temperature, the floor noise, the sinking of the floor, and the falling off of the small joist 5 are prevented. be able to.

By the way, in the first embodiment, as described above, the cutouts 22 are provided so that the arrangement area of the header member 7 is made independent of the bending deformation of the mat body 2. When the mat body 2 is bent inward, the small mat substrates 4 (4a, 4b) arranged on the left and right sides of the notch 20 approach the header member 7 (α shown in FIG. 1B). , Β direction).

In such a case, the straight portion of the pipe 6 linearly arranged from the header member 7 along the bending direction of the mat body 2 is inserted into the pipe groove 11 from the header member 7 as shown in FIG. (A) is shifted in the direction toward the bent portion 23, and by this shifted movement,

Even when the small joist 3 is arranged in the vicinity of the arrangement area of the header member 7, when the mat body 2 is bent, it is possible to reliably prevent the header member 7 from rising out of the notch 20. Thus, it is possible to reliably avoid the problem caused by the lifting of the header member 7.

Hereinafter, a third embodiment will be described. In the description of the third embodiment, the same components as those of the above embodiments are denoted by the same reference numerals, and the overlapping description of the common portions will be omitted.

The third embodiment is different from the above embodiments in that the notch 20 has an opening on the bottom side of the mat body as shown in FIGS. 7 (a) and 7 (b). That is, an insulating sheet 34 that is an insulating member that covers the header member 7 is formed. Other configurations are the same as those of the above embodiments.

The insulating sheet 34 is made of an insulating material such as plastic or nylon. For example, the insulating sheet 34 is attached to the opening edge of the notch 20 on the bottom surface side of the mat body with an adhesive or an adhesive tape to form a header member. 7 is covered.

In the third embodiment, as described above,
An insulating sheet 34 is attached to an opening edge of the notch 20 on the bottom surface side of the mat body. When the mat body 2 is bent with the aluminum foil 12 inside, when the arrangement area of the header member 7 is bent together with the bending deformation of the mat body 2 as in the related art, a large tensile force is applied to the insulating sheet 34. This causes a problem that the insulating sheet 34 is peeled off.

On the other hand, in the third embodiment, since the area where the header member 7 is provided is independent of the bending deformation of the mat body 2 as described above, the aluminum foil 12 is When the mat body 2 is bent, a large tensile force can be suppressed from acting on the insulating sheet 34, and the insulating sheet 34 can be prevented from peeling off.

Further, in the third embodiment, in addition to having the configuration of each of the above embodiments, the opening of the notch 20 on the bottom side of the mat body is provided with an insulating material for covering the bottom side of the header member 7. Since the sheet 34 is provided, the following nailing inspection can be accurately performed when the heating mat 1 is laid.

The nailing inspection is an inspection for checking whether or not the nail 16 has erroneously punched the pipe 6.
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 nail 16
Water leaks from the pipe portion into which the gas is injected, which is a serious problem. Therefore, the nailing inspection is performed.

The nailing inspection is performed by checking whether the aluminum foil 12 and the header member 7 can be energized while water is present in the pipe 6. That is, when the header member 7 is formed of a conductive material, the header member 7 is in a state capable of conducting electricity with water in the pipe 6. If the nail 16 pierces the pipe 6, the water in the pipe 6 can be electrically connected to the aluminum foil 12 via 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 does not punch the pipe 6, the water in the pipe 6 and the aluminum foil 12 are in an insulated state. No current path is formed through the member 7, the water in the pipe 6, and the aluminum foil 12.

From this, it is possible to conduct electricity between the header member 7 and the aluminum foil 12 by using a very sensitive tester.
By examining the impossibility, it can be inspected whether or not the nail 16 has punched the pipe 6. That is, when the header member 7 and the aluminum foil 12 are energized, the nail 16
Is determined that the pipe 6 has been punched, and when the header member 7 and the aluminum foil 12 are not energized, it is determined that the nail 16 has not punched the pipe 6.

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 supplied. And the water on the floor panel 14 is
And the aluminum foil 12 can be energized, so that the header member 7, the water on the floor panel 14, the nail 16 and the aluminum foil 1
2 is formed, so that the nail 16
Irrespective of whether or not the nails are driven into the pipe 6, the header member 7 and the aluminum foil 12 are in a state where they can be energized, so that there is a problem that an accurate nailing inspection result cannot be obtained.

In the third embodiment, since the insulating sheet 34 covering the header member 7 is formed at the opening of the cutout 20 on the bottom surface side of the mat body as described above, the floor panel 1
4 and the header member 7 can be insulated from each other, and even if the floor panel 14 is wet, the water flowing through the header member 7 and the floor panel 14, the nail 16, and the aluminum foil 12 A path will not be formed, which will give an accurate nailing inspection result.

[0090]

According to the present invention, there is provided a lift suppressing means for making the arrangement region of the header member independent of the bending deformation of the mat portion and suppressing the lifting of the header member from the header accommodating portion caused by the bending deformation of the mat portion. When the mat is bent with the heat dissipating material inside, the lifting of the header member from the header housing part is suppressed, preventing the header member connection end of the pipe from floating from the pipe groove can do.

Further, in a heating mat having a pipe groove formed with a U-turn portion and being drawn around, the U-turn portion forming region of the pipe groove is independent of the bending deformation of the mat portion, and the bending deformation of the mat portion is performed. In the apparatus provided with the lifting suppression means for suppressing the lifting of the pipe from the U-turn portion of the pipe groove caused by the above, it is possible to prevent the pipe from rising from the U-turn portion of the pipe groove.

As described above, since the connection end of the header member and the U-turn portion of the pipe can be prevented from rising from the pipe groove, the problem caused by the lifting of the pipe from the pipe groove, that is, the heating of the pipe, can be prevented. The problem of uneven temperature, the problem of floor noise, the problem of sinking of the floor, the problem of falling off of components, and the like can be avoided.

In the case where the means for preventing lifting is constituted by cuts along the bending direction of the mat portion penetrating from the heat radiating material to the bottom surface of the mat portion, the cuts are simply formed in the mat portion. With the configuration, the arrangement region of the header member and the U-turn portion formation region of the pipe groove can be made independent of the bending deformation of the mat portion, so that the lifting of the header member and the pipe can be suppressed. The resulting problem can be prevented.

A joist is provided in the area where the lift suppressing means is formed in the mat portion. In the case where the notch serving as the lift suppressing means is also formed on the joist, the joist is formed in the area where the lift suppressing means is formed.

One or more of the bends in the pipe groove are formed so that the width of the pipe groove allows the pipe to shift, and the wide bend is provided with a pipe support member for absorbing and supporting the shift of the pipe. In the case of the mat, for example, as in the case where the mat portion is bent, the pipe shifts in a direction from the straight portion in the bending direction of the mat portion toward the bent portion, and the pipe is loosened at the bent portion. At this time, the wide bent portion can absorb the slack of the pipe, can suppress the slack portion of the pipe from rising from the pipe groove, and can prevent the problem caused by the rising of the pipe. . In addition, since the pipe support member is provided at the wide bent portion as described above, it is possible to prevent the pipe from playing at the wide bent portion.

When the pipe support member is a member integral with the pipe wall in which the groove wall of the pipe groove is projected and deformed,
Since the pipe supporting member is formed at the same time when the pipe groove is formed, an increase in the number of manufacturing steps can be suppressed.

The pipe support member may be a member independent of the pipe groove wall attached to the pipe groove, or a member in which the wide pipe groove forming piece is incorporated in the wide bend forming area of the pipe groove path of the mat portion. In this case, it is possible to relax restrictions on the form that can be adopted as the pipe support member.

[0098] In a device provided with a protrusion preventing means for preventing a slack portion of the pipe from running on the pipe supporting member and escaping from the pipe groove, the slack portion of the pipe is not supported by the pipe supporting member. The problem that occurs when a pipe protrudes from a pipe groove, that is, because
It is possible to avoid the same problem as the problem caused by the lifting of the pipe.

The header accommodating portion is formed by a notch formed in the mat portion, and at least the opening of the mat top surface and the opening of the mat bottom surface of the notch cover the header member at least in the opening of the mat bottom surface. In the case where the member is formed, in the conventional configuration in which the arrangement region of the header member tries to bend together with the bending deformation of the mat portion,
When the mat portion is bent with the heat dissipating material inside, there is a problem that a large tensile force acts on the insulating member formed at the opening on the bottom surface side of the mat portion of the cutout and the insulating member falls. On the other hand, in the present invention, since the arrangement region of the header member is independent of the bending deformation of the mat portion, when the mat portion is bent with the heat dissipating material inside, the cut-out mat A large tensile force does not act on the insulating member formed at the opening on the bottom surface side, and the problem that the insulating member falls can be prevented.
