[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an improvement of a partial heat generating floor material used for a heat generating floor of a house, particularly a peripheral portion of a heat generating floor of a room, and a manufacturing method thereof.

[0002]

2. Description of the Related Art As a prior art, the actual Kaihei 1-63090
The publication discloses an example of a heating floor material having a heating element incorporated therein. When the floor surface of a room is constructed using such a heating floor material, a heating element is not installed inside the room where heat is not required, such as the peripheral part of the room where furniture is installed. It was necessary to prepare a non-fever flooring material with the same thickness and same makeup as the material and lay it separately, and to lay a heat-generating flooring material in the center of the room. Therefore, we proposed a partially heating floor material that partially contains a heating element.
In this case, if there is a heat-generating part and a non-heat-generating part in one floor panel, when the heat is generated, a difference in water content between the heat-generating part and the non-heat-generating part or a difference in contraction / expansion due to a heat change may occur, which may affect each other. As a result, there is a problem that the partially heated floor material is warped or twisted. In addition, since there is a lot of unevenness in the floor base portion at the peripheral portion of the room, there is a drawback that a rigid floor material is likely to cause adhesion failure with the floor base during construction.

DISCLOSURE OF THE INVENTION The present invention relates to a partially heat-generating flooring material in which a heat-generating part is partially arranged, which is easily adapted to the unevenness of the floor base during construction and does not warp or twist during heat generation. The purpose is to provide a flooring material and a manufacturing method thereof.

A partially heating floor material according to the present invention is a "rectangular surface material (1) and a long side frame material disposed at the long side end of the rectangular surface material (1). (7), a heat generating part (H) and a non-heat generating part (C) formed between the long side frame members (7) on the lower surface side of the rectangular surface material (1), and a heat generating part (H ) And non-heating part
In the partial heating floor material (A) composed of the rectangular backing material (5) arranged on the back side of (C), the heating part (H) and the non-heating part (C) are separated from each other. A gap (9) is formed, and the rectangular back surface material (5) and the long side frame material (7) are divided into a heat generating portion (H) and a non-heat generating portion (C) in accordance with the gap (9). The dividing grooves (8) are formed in the rectangular back surface material (5) and the long side frame material (7) respectively ”.

As a result, the heat generating portion (H) and the non-heat generating portion (C) are completely separated except for the rectangular surface material (1) or the remaining portion of the long side frame member (7) left uncut, The heat generating part (H) can be expanded and contracted regardless of the non-heat generating part (C), so that internal stress does not accumulate as a whole and the floor material (A) is unlikely to warp or twist. In addition, even if there is unevenness on the floor base, only the rectangular surface material (1) or the uncut portion was left uncut as described above in the gap (9) part that divides the heat generating part (H) and the non-heat generating part (C). Since only the remaining portion of the long-side frame (7) is present, it can be easily bent in response to unevenness, can absorb the unevenness, and can be sufficiently adhered to the floor base.

Further, the method for producing a partially heating floor material (A) according to the present invention is that "long side frame members (7) are arranged at both long side edges of the rectangular surface plate (1) to form a frame. A heat generating part (H) is formed by disposing a heat insulating material (4) on one side between the materials (7) via a heat generating material (2) and at the same time a frame material.
On the other side between (7), a filler (6) having a thickness approximately equal to the total thickness of the heat generating material (2) and the heat insulating material (4) is arranged to form a non-heat generating portion (C). A gap that divides the heat generating part (H) and the non-heat generating part (C)
(9) is provided between the heat generating part (H) and the non-heat generating part (C), and then the rectangular back plate (5) is attached to the heat insulating material (4) and the non-heat generating part (C) of the heat generating part (2). )

DESCRIPTION OF THE PREFERRED EMBODIMENTS This embodiment will be described below with reference to the drawings. The partial heating floor material (A) is roughly divided into a heating portion (H) and a non-heating portion (C). The area ratio between the heat-generating part (H) and the non-heat-generating part (C) is, for example, half of the heat-generating part (H), 1/3, 2/3. It is used according to the situation.

FIG. 1 is a partially cutaway perspective view of the partially heating flooring material (A) according to the present invention as seen from the back side, and FIG. 2 is a longitudinal sectional view of the first embodiment. On the side, the rectangular surface material (1), the heat equalizing plate (3), the heating element (2), the heat insulating material (4) and the rectangular back surface material (5) are laminated from the front side, and the non-heat generating part On the side (C), the rectangular surface material (1), the filling material (6), and the rectangular back surface material (5) are laminated from the front side. Insulation material for heat generating part (H)
A control device (not shown) for controlling the temperature of the heating element (2) is built in the (4), and (14) is a mold member that houses the control device. As a control device, a lead wire (10) is a thermistor and a fuse, which are connected to each other. In this embodiment, an example of using the heat equalizing plate (3) is shown, but when the aluminum foil is integrally laminated on the upper surface of the heating element (2), the aluminum foil is the heat equalizing plate. (3)
Since it has the same function as, it is not necessary to prepare a separate heat equalizing plate (3).

The rectangular surface material (1) used in the present invention is a laminate of veneer laminating boards, decorative boards such as WPC treated decorative boards, and the rectangular back surface material (5) is FRP, resin impregnated sheet or the like. It is composed of a resin plate, a wood plate such as plywood, and an inorganic plate such as a calcareous plate. The surface position corresponding to the gap (9) described later traverses parallel to the short side or partially with a V groove or a veneer joint, You may provide a linear pattern (1 '). (7) is a long-side frame material, (11) is a short-side frame material, and is arranged and fixed between the side edge portions of the rectangular surface material (1) and the rectangular back surface material (5). (12) is a male fruit formed on the frame members (7) and (11), and (13) is a female fruit. By using these fruits and connecting them together, there is no step difference with the floor material (A) that is connected.

The heat insulating material (4) is made of wood such as insulation board, glass wool, rock wool board, urethane foam, foamed phenol, wood, inorganic material, and synthetic resin foam. 5) Filled between and.

As the heating element (2), a wire heater or a surface heating element in which electrothermal resin is laminated and integrated is used. In this embodiment, the surface heating element (2) using a wire heater is used, and a resin layer or an aluminum foil is laminated on the front and back of the surface heating element (2) so as to provide uniform heating and waterproof treatment, It is arranged on the lower surface of the rectangular surface material (1). Further, an insulating sheet and a heat equalizing plate (3) are appropriately laminated on the front and back of the surface heating element (2) to improve safety and thermal efficiency.

A method of separating the heat generating portion (H) and the non-heat generating portion (C) will be described. As shown in Fig. 4, frame members (7) and (11) are arranged on both long side edges and short side edges of the rectangular surface plate, respectively.
A heat insulating material (4) is disposed between the frame members (7) through the heat generating material so that the heat generating portion (H) is fixed to one half or one-third or two-thirds of the whole. In this case, when the aluminum foil is not attached to the surface of the heating element (2) as described above, the separate soaking plate (3) is used as the heating element (2) and the rectangular surface material (1). The heat equalizing plate (3) can be omitted when the aluminum foil is attached. In this way, the heat generating portion (H) side is configured.

On the other hand, on the non-heat generating portion (C) side, the frame member (7)
The filling material (6) having a thickness substantially equal to the total thickness of the heat generating material (2) and the heat insulating material (4) is disposed and formed in the remaining portion between them.
At this time, the heat generating part (H) is placed between the heat generating part (H) and the non-heat generating part (C).
A gap (9) is provided to separate the heat generating portion (C) from the heat generating portion (C).
Then, a rectangular back plate (5) having the same size as the rectangular surface material (1) is arranged and integrated with the heat insulating material (4) and the filling material (6) to form a semi-finished product having the shape shown in FIG. .

Finally, a rectangular back plate along the gap (9)
At the same time as cutting out so as to cross (5), the long side frame material (7)
Form a kerf (8) in the. The rectangular backing material (5) and the long side frame material
The cutting method of (7) is as shown in Fig. 2, so that the long side frame material (7) is completely cut at the same time as the gap (9) and only the rectangular surface material (1) remains. Alternatively, as shown in FIG. 3 or 5, the rectangular backing material (5) has a cutting width smaller than the gap (9) and smaller than the height of the long-side frame material (7) so that the long-side frame A part of the material (7) may be left. In the case of FIG.
This is an example in which the kerf (8) is close to the non-heat generating portion (C) side, and FIG. 5 is an example in which it is located in the center. Of course, although not shown, the kerf (8) may be close to the heat generating portion (H) side,
Also, the width of the kerf (8) is made equal to the width of the gap (9), and at the same time, it is made shallower than the height of the long side frame (7) so that a part of the long side frame (7) is left. May be.

From the control device (5) of the heating element (2) to the lead wire (10)
However, in this partial heating floor material, in the present embodiment, a special storage recess for storing the lead wire (10) is not formed, and the lead wire (10) is provided in the gap (9). ) Will be stored. Of course, if necessary, the storage recess can be formed in particular. Further, in the embodiment shown in the drawings, an example is shown in which only the kerf (8) is formed so as to traverse the rectangular backing material (5), but the non-heat generating portion (C) is short from the kerf (8). It is also possible to form a cut groove (8) through which the side frame member (11) is pulled out.

Then, the heating floor material (A) is laid on the floor base (12). First, the power source (not shown), the controller (not shown) and the heating floor material (A) are connected to each other. Lead wire (1
Connect 0). Subsequently, the connection portion (10) and the lead wire (10) are stored in the gap (9), and then directly laid on the floor base (12) such as plywood or concrete slab. Although the floor base (12) is uneven, the part corresponding to the gap (9) dividing the non-heat generating part (C) and the heat generating part (H) has a rectangular surface material as shown in FIG.
(1) only, or rectangular surface material (1) and kerf as shown in FIGS.
Since it is composed of only the long side frame material (7) that is cut off by (8) and is easy to bend, it is easy to bend along the unevenness and it is possible to easily absorb the unevenness of the floor base. it can. Therefore, the occurrence of defective adhesion to the floor base is significantly reduced. At this time, if a V groove, a seam of a veneer, or a linear pattern (1 ') is provided on the surface corresponding to the gap (9), positioning with an adjacent heating floor material is facilitated and the V groove is used for preventing warpage. More effective. In addition, the heating floor material (A) is used as a concrete slab.
When directly attached to (12), if a cushioning material such as foamed plastic is laminated on the lower surface to form a rectangular back surface material (5), the conformability to the floor surface and the heat insulating property are improved.

When heating the floor (2), the heating element (2) is energized to raise the temperature of the heating section (H), and the heat is transferred to the rectangular surface material (1) on the heating section (H) side. Temperature rises.
At the same time, heat generation causes the water content of the heat generating portion (H) to decrease and shrink. On the contrary, when the heating element (2) is de-energized and floor heating is stopped, the heating section (H) also cools to room temperature and absorbs moisture to expand. On the other hand, since the non-heat generating portion (H) is separated by the gap (9) as described above, almost no heat is transferred, and since the temperature does not rise, the water content does not decrease, and there is no shrinkage. However, as described above, since the heat generating part (H) and the non-heat generating part (C) are completely separated by the gap (9), the rectangular surface material (when the floor heating is not performed and when the floor heating is not performed) 1) to the long side frame member (7) except for the remaining part that was cut off, repeated expansion and contraction independently of each other, the non-heating part and the heating part were not separated, and the whole was integrated Compared with the partially heated floor material, internal stress is less likely to occur and warpage and twisting are less likely to occur.

[0019]

According to the partially heating floor material of the present invention, a gap is formed between the heat generating portion and the non-heat generating portion so as to separate them from each other, and the rectangular back surface material and the long side frame material are matched with the gap. Since the cut grooves for dividing the heat generating portion and the non-heat generating portion into the rectangular back surface material and the long side frame material are respectively engraved, the heat generating portion and the non-heat generating portion are left with only the rectangular surface material or left uncut. It is completely separated except the rest of the long side frame material, the heat generating part can expand and contract independently of the non heat generating part, internal stress does not accumulate as a whole, and it is difficult to cause warping or twisting to the floor material There are advantages.
Also, even if there is unevenness in the floor base, there is only the rectangular surface material or the remaining part of the long-side frame material left uncut, as described above, in the part of the gap that divides the heat generating part and the non-heat generating part. It also has the advantage that it can be easily bent in response to land, absorbs unevenness, and can be sufficiently bonded to the floor base.

Further, in the method for manufacturing a partially heating floor material according to the present invention, the long side frame members are arranged at both long side edges of the rectangular surface plate, and a gap is provided on one side between the frame members. A heat generating part is formed and a non-heat generating part is formed on the other side, and then a rectangular back plate is disposed and integrated on the back side of the heat generating part and the non-heat generating part, and the rectangular back plate and the long side are arranged along the gap. Since the kerf is formed in the side frame member, the heat generating portion and the non-heat generating portion can be almost completely separated from each other, and as described above, the kerf is finally formed along the gap. There is also an advantage that the shape and position such as the width and depth of the kerf formed in the back surface material and the long side frame material can be freely selected.
