BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft floor heating mat suitable for underfloor laying.

[0002]

2. Description of the Related Art Piping grooves are formed in a meandering manner on a substrate sheet made of a thermoplastic resin foam, which is a heat insulating layer, and a conduit for circulating a heat medium is laid in the piping grooves. A soft floor heating mat coated with a covering material such as an aluminum foil is known (see Japanese Utility Model Laid-Open No. 2-67808). In order to lay this soft floor heating mat under the floor, a method of laying the soft floor heating mat on a floor base with the covering material side facing upward, laying a surface floor material thereon, and fixing it by nailing Is generally adopted.

[0003]

The surface floor material laid on the above-mentioned known soft floor heating mat is often bent by the flexibility of the mat, and it is laid under the floor and nailed. In the fixing operation, it is difficult to determine a nailing position, and nailing is performed depending on a feeling. Therefore, a problem that a conduit is nailed by mistake easily occurs. Therefore, a soft floor heating mat that solves such a problem is proposed by the present applicant as Japanese Utility Model Application No. 4-66652. It has a structure in which a nailable member such as wood is embedded in the sheet with respect to the entire thickness of the base sheet.

In order to fix the soft floor heating mat together with the surface floor material on the floor base by nailing, an adhesive is applied to a nailable member and the soft floor heating mat laid on the floor base. Is temporarily fixed in advance. Then, the adhesive is applied to the back surface of the nailable member by turning the soft floor heating mat upside down, or the soft floor heating mat is wound so that the nailable member is on the outside, and the nail is rewound. Since the material is applied to the back surface of the strikable member, the workability is very poor, and a measure for improving the workability has been demanded.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to improve a soft floor so that the operation of applying an adhesive to a nailable member can be easily performed without much labor. It is to provide a heating mat.

[0006]

In order to achieve the above object, a soft floor heating mat characterized by the present invention is a conduit through which a heat medium flows on a base sheet made of thermoplastic resin foam which is a heat insulating layer. Laying in a meandering state, a soft floor heating mat with aluminum foil adhered to the surface side of the base sheet,
A nailable member that is not bonded to the base sheet but bonded to the aluminum foil is embedded in the base sheet between the conduits, while the aluminum foil is formed of a nailable member. A cut is provided along a part of the long side just above the edge.

[0007]

[Function] With the mat laid, the nailable member is turned over on the mat by using the notch together with the aluminum foil of the part bonded to this member,
An adhesive can be applied to the back surface of the nailable member.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3, reference numeral 1 denotes a base sheet made of a thermoplastic resin foam such as polystyrene or cross-linked polyethylene having a closed-cell structure, and a heating medium such as hot water is distributed on the base sheet 1 separately. A plurality of conduits 2 (usually two to five, but two in the illustrated case) are arranged in a meandering state in parallel with each other.

[0009] The conduits 2 and 2 are laid in piping grooves 3 and 3 which are previously provided in a meandering manner on the base material sheet 1, and both ends thereof are respectively connected to a header 4 provided in the middle of the laid portion. Have been. In FIG. 1, a small portion of the conduit (a small portion of the conduit laid in a direction different from the laying direction of most of the conduits (the laying portion is indicated by reference character a)) linearly laid in the same direction is shown. The laying portion is indicated by a symbol “b”) in a piping state where the laying portion is laid at a piping pitch of 5 to 30 mm (distance between centers of conduits) at the top of the bent portion.

Further, the base sheet 1 is positioned between the laid conduits 2 and 2 so that one end 5a reaches the edge 1a of the base sheet 1 with respect to the entire thickness of the base sheet 1. A nailable member 5 is embedded in advance, and the member 5 and the base sheet 1 are not bonded. The nailable member 5 is made of wood or synthetic wood, and has a width of 15 to 60 m.
m, a timber having a height of about 3 to 20 mm is used.
The pitch between them is 303 ± 10 mm as the center-to-center distance.
And, as a matter of course, the other end 5 b of the member 5 faces the inside of the curved portion of the conduit 2.

On the other hand, after the conduit 2 is laid and the nailable member 5 is buried, an aluminum foil 6 as a heat conductive material is adhered to the surface side of the base sheet 1 using an adhesive.
As shown in FIGS. 2 and 3, the aluminum foil 6 is provided with a cut 7 along the edge of the nailable member 5 at a portion facing just above the edge on one long side of the member 5 to provide a soft floor heating mat. In particular, a soft underfloor heating mat for underfloor installation is constructed.
In the illustrated embodiment, the cut 7 is provided so as to extend to a portion directly above the edge on the short side of the nailable member 5, but this is a portion of the portion directly above the edge on the short side. The cut may be omitted, or may be provided so as to remove the portion near the edge 6a of the aluminum foil 6.

In the above structure, the base sheet 1 is preferably made of a low-density polyethylene cross-linked foam having an expansion ratio of 10 to 40 times and a thickness of 3 to 20 mm.
For example, when the thickness of the base sheet 1 is 10 mm, it is preferable to use a crosslinked body of low-density polyethylene having an outer diameter of 8 mm and an inner diameter of 5 mm. Further, the piping pitch of the conduits in the laying portion a of most conduits is 30 to 15
0 mm, preferably 50-100 mm, while the aforementioned piping pitch at the top of the bend in the laying part b of the small part of the conduit is preferably 5-15 mm. The sum of the lengths of the conduits at the small part of the conduit laying portion b is 30% of the total length of the conduits laid on the base sheet 1.
Or less, preferably 15% or less (conventionally 40 to 50%)
%).

In the present invention, the piping pitch at the top of the bent portion in the laying portion b of the small portion of the conduit is not limited to the above, and the piping pitch at the laying portion a of most of the conduits is not limited to the above. It may be the same as the pitch.

[0014] The floor heating mat burn them <br/> laid under the floor in the following manner. First, the bed base 11 soft Shitsuyuka heating mat, as shown in FIG. 4 as 6 side aluminum foil becomes top
Then, the nailable member 5 is turned upside down on the mat by using the notch 7 together with the aluminum foil 6 of the part adhered to the member 5 (indicated by the phantom line in FIG. 2). Apply adhesive to the back side. in this case,
The substrate sheet 1 itself has elasticity, and because the base sheet 1 and the nailing capable member 5 is not bonded, the member 5 is rotated to the opposite side portion of the cut 7 as a fulcrum of aluminum foil 6, Right above the short side edge of the nailable member 5
Along the short side edge of the aluminum foil 6
Even if the notch is not provided, the aluminum
When the member 5 which can be nailed is turned over, the member 5 is turned over.
The member 5 that can be forcibly torn by force and nailed
Ru can be reversed on the mat.

Then, the nailable member 5 is returned to the original buried state, and after being adhered to the floor base 11, a surface flooring material 12 is laid on the mat, and the nailable member 5 is interposed. The surface floor material 12 is fixed by nailing. In the figure, reference numeral 12a denotes a phase-less connecting portion formed between the surface floor materials 12. It is to be noted that a synthetic resin film for reinforcement may be laminated and adhered to the back side of the base sheet 1, but in this case, the synthetic resin film has a portion directly above the edge of the nailable member 5. Are provided with cuts along the entire periphery of the edge.

[0016]

[Effect of the Invention] The present invention is as described above, and the load resistance of the mat can be improved and nailing can be carried out by the presence of a nailable member without impairing the original mat winding property of the soft floor heating mat. The location can be easily determined, and the work of laying under the floor can be performed safely. Also, since the nailable member can be inverted on the mat, the adhesive can be applied to the back surface of the member at the inverted position, which is very convenient for applying the adhesive, and the workability is further improved. There is an effect that can be improved.
