Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a soft floor heating mat on a floor in a room.

[0002]

2. Description of the Related Art A soft floor heating mat laid so as to eliminate a step between a floor in the room and a soft floor heating mat laid on the floor has an intermediate portion of the floor surface in the room. There is known a structure in which a soft floor heating mat is laid in a part, and an underlaying material is laid in a state flush with the mat on a portion of the floor surface extending from the edge of the soft floor heating mat to the corner of the floor. (See Japanese Utility Model Laid-Open No. 63-55013).

[0003]

In the above-mentioned known laying section, since the underlayment is made of felt or synthetic resin foam having the same expansion ratio as the base sheet, the heat medium is circulated in the conduit. Even when the mat edge hits the underlay material edge due to the thermal expansion of the base sheet and the conduit when the mat is used, the underlay material cannot absorb the expansive force of the mat and the mat edge rises, There is a problem that the carpet etc. laid on top is partially lifted.

On the other hand, it is conceivable that the mat and the underlayment material are laid with a gap corresponding to the thermal expansion amount of the mat as a joint portion, but it is difficult to lay the joint and the underlaying material with a certain width. There is a problem above. In addition, when the mat is not used, when it is stepped on, a dent occurs in the joint part, which appears as a step on the carpet surface as an overlay material, which not only looks bad but also makes the foot feel bad. There is also.

The present invention has solved these problems, and its purpose is to allow the joint portion to absorb the thermal expansion of the base material sheet and the conduit when the mat is used, so that the edge of the mat rises. It is an object of the present invention to provide a method for laying a soft floor heating mat, which can solve the phenomenon and at the same time prevent dents which are likely to occur in the joint portion when the mat is not used.

[0006]

In order to achieve the above object, a method for laying a soft floor heating mat, which is a feature of the present invention, is such that a heat medium is placed on a base sheet made of synthetic resin foam which is a heat insulating layer. A soft floor heating mat, in which a conduit for circulation is laid and a covering material is applied to the surface side, is laid in the middle part of the indoor floor surface, and the edge of the soft floor heating mat reaches the corner of the floor. After laying the underlayment in a portion flush with the mat on the floor surface, the edge of the underlayment facing the soft floor heating mat is cut into a predetermined width and the cut portion is removed. A joint portion is formed, and a joint material made of a synthetic resin foam having a higher expansion ratio than the expansion ratio of the base sheet is laid on the joint portion.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. A soft floor heating mat 1 used in the practice of the present invention includes a base sheet 2 made of synthetic resin foam, a conduit 3 laid on the front surface side of the base sheet 2 for circulating a heating medium such as hot water, and the like. It is composed of a covering material 5 which covers the conduit 3 and adheres to the base material sheet 2.

The conduit 3 is a pipe groove 4 provided on the base sheet 2.
In the illustrated case, three pipe grooves 4 are provided in a meandering shape in parallel with each other. Both ends of each pipe groove 4 are gathered at the peripheral edge portion of the base material sheet 2, and the inlet end portion 7a of the header provided in this gathering portion 6 has the starting end portion of each conduit 3 and the return port portion 7b. Is each conduit 3
Are connected to each other.

Next, a method for laying the soft floor heating mat according to the present invention will be described. A soft floor heating mat 1 is laid in the middle of a floor surface 11 in a room, and the soft floor heating mat 1 is flush with the mat 1 at a portion on the floor surface 11 from an edge 1a to a corner 11a of the floor. In this state, the underlayment material 8 is laid. After that, the edge side of the underlayment 8 facing the soft floor heating mat 1 is cut into a predetermined width, and the cut portion is removed to form a joint portion, and the joint portion is formed according to the expansion ratio of the base sheet. A joint material 9 made of a synthetic resin foam having a high expansion ratio is laid.

In the above structure, the expansion ratio E ₂ of the joint material 9 made of synthetic resin foam is preferably

[0011]

[Equation 1]

Particularly preferably,

[0013]

[Equation 2]

When the upper limit is exceeded, a step is likely to occur at the joint material 9 when the mat is not used, and this step appears on the carpet surface as the overlay material, which not only gives a bad appearance but also gives a bad feel to the feet. On the other hand, if it is less than the lower limit, the mat edge may hit the joint material edge due to thermal expansion during use of the mat, and the mat edge may float and lift the carpet. Here, E ₁ is the expansion ratio of the base sheet, W ₁ is the expansion width (mm) of the base sheet,
W ₂ is the width (mm) of the joint material.

The joint material 9 may be made of polyethylene, polyurethane, rubber or the like. It is preferable to use the same material as that of the base sheet 2 (described later), and its width is about 5 to 50 mm. Is. For example, when the expansion ratio of the base material sheet 2 is 20 times, the width of the joint material 9 and the expansion ratio are tentatively determined to be 7.5 mm, 10 mm and 15 mm.
Foaming ratio is 60 times for mm and 20 mm, 4
It is about 0 times, 30 times, and 27 times. The predetermined width at which the underlayment material 8 is cut into a predetermined width to form the joint portion is substantially the same width as the joint material 9.

The synthetic resin foam used as the material of the base sheet 2 is a foam of polyolefin, polyurethane, rubber or the like having a foaming ratio of 10 to 40 times and a thickness of 5 to 20 mm. In particular, low density polyethylene is crosslinked. It is preferable to use a foam, and the conduit 3 has, for example, a thickness of the base sheet 2 of 1
In the case of 0 mm, it is preferable to use a synthetic resin tube such as a polyolefin having an outer diameter of 8 mm and an inner diameter of 5 mm, particularly a low density crosslinked polyethylene tube. Aluminum foil, thermoplastic resin film and its foam, woven fabric, non-woven fabric, etc. are used as the material of the covering material 5, and the material of the underlaying material 8 is the same as the foaming ratio of the felt or the base sheet 2. A synthetic resin foam or the like having an expansion ratio of is used.

As described above, according to the method of the present invention, the soft underfloor heating mat 1 is surrounded and the underlayment 8 is laid, and then the underlayment 8 is placed.
Since the joint edge portion is formed by cutting and removing the edge side portion facing the soft floor heating mat 1 into a predetermined width, a joint material 9 capable of absorbing the thermal expansion of the mat is formed between the soft floor heating mat 1 and the underlayment material 8. It can be provided in a uniform width with good appearance, and can be easily laid, and it is possible to solve the problem that a step or the like is generated on the surface of the carpet 12 as the overlay material regardless of whether the mat is used or not.

[0018]

EFFECTS OF THE INVENTION According to the method of the present invention, it is possible to easily construct the laid portion in which the joint material which can absorb the thermal expansion of the mat is present between the soft floor heating mat and the underlaying material laid around the soft floor heating mat. it can. Since the joint material is made of synthetic resin foam, which is a specified material that does not easily dent when it is stepped on, the carpet can be laid in a good appearance over the entire laid portion and at the same time the carpet can be laid. It is possible to completely eliminate the steps that are likely to appear on the surface of the.
