Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-generating floorboard which is excellent in waterproofing and moisture-proofing and has good adhesiveness to a floor base material.

[0002]

2. Description of the Related Art Conventionally, as a heating floor plate of this type,
For example, a structure as described in Japanese Utility Model Publication No. 62-59991 is known. That is, this heating floorboard
A heat insulating material and a surface heating element are stacked and filled in the space between the wooden frame bodies fixed on both end portions of the wooden lower surface plate, and the wood surface plate is placed between the upper surfaces of the frame bodies in contact with the upper surface of the surface heating element. It has a structure fixed to the.

[0003]

However, in the heat generating floor plate as described above, since the bottom plate is made of a wood material, vinyl acetate resin is used on the floor base panel on which plywood, particle boats, etc. are laid. If steps, minute irregularities, or curved surfaces are generated on the floor base surface when bonding with an adhesive or the like, it becomes difficult to bring the wood bottom plate into complete contact with the floor base panel, resulting in poor adhesion. It is easy to occur,
Further, there is a problem that moisture is accumulated in the minute gaps between the bottom plate and the floor base panel to further promote the above adhesion failure.

Moisture permeates from the back surface side of the floor base material into the floor base panel and the wood bottom plate to enter the heat generating floor plate,
This causes internal dew condensation to deteriorate electric parts, and warps or deforms the entire heating floorboard, making it impossible to endure long-term use. Such infiltration of moisture can be dealt with by interposing a moisture-proof sheet between the wooden lower plate and the heat insulating material, but using a moisture-proof sheet increases the number of parts and increases the cost of the product. In addition, it is not possible to prevent the permeation of moisture from the wooden frame that is fixed on both ends of the wooden lower surface plate.

Therefore, it is conceivable to use a moisture-impermeable metal thin plate or a synthetic resin plate in place of the wooden lower plate, but these adhesives such as vinyl acetate, which are commonly used, do not have good adhesion to the floor base panel. There is a problem in workability due to bad or poor solvent absorption of the adhesive. It is an object of the present invention to provide a heating floorboard that can completely eliminate such problems.

[0006]

In order to achieve the above object, the heat generating floor board of the present invention comprises a wooden crosspiece in the longitudinal direction of both side ends on the upper surface of a rectangular lower surface plate made of a thermosetting resin impregnated sheet. The heat insulating material and the heating element are laminated on the floor board between the wooden crosspieces, and the wooden surface board is fixed between the upper surfaces of the wooden crosspieces.

[0007]

[Function] Since the thermosetting resin-impregnated sheet is used as the lower surface plate of the heat generating floor plate, even if a step or a minute uneven surface is generated on the floor base panel, the surface is familiar and closely warped along the surface. Accurate construction is possible without floating, and when bonding with a normal adhesive on the floor base panel, reliable adhesion can be achieved without causing adhesion defects like metal plates and synthetic resin plates. You can do it.

Further, even if moisture enters from the back surface side of the floor base panel, the thermosetting resin-impregnated sheet becomes a barrier layer against moisture, and the moisture is directly introduced through the bottom plate or inside the heat-generating floor plate through the wooden crosspiece. Intrusion is prevented, and there is no risk of deterioration of internal electric parts and the like.

[0009]

EXAMPLE An example of the present invention will now be described with reference to the drawings. In the heating floor plate, a long rectangular thermosetting resin-impregnated sheet having a constant width is used as the lower surface plate 1, and both sides of the lower surface plate 1 are used. Square bar-shaped crosspieces 2 and 2 are fixed by an adhesive in the longitudinal direction of the upper surface of the end portion, and a heat insulating material 3 and a heating element 4 are provided on the upper surface of the lower plate 1 in the space between these crosspieces 2 and 2.
Are arranged in the order of being stacked, and further, the surface plates 5 are overlapped so that the lower surface is in contact with the upper surface of the heating element 4, and the lower surfaces at both end portions of the surface plate 5 are both crosspieces 2, It is integrally fixed to the upper surface of 2 with an adhesive or a nail.

In the heat-generating floorboard having the above-mentioned structure, the thermosetting resin-impregnated sheet forming the bottom plate 1 of the heat-generating floorboard is a thermosetting resin liquid such as melamine, phenol, diallyl phthalate or benzoguanamine resin. It is made by impregnating and curing cloth, cloth, etc., and its thickness is 0.
It is formed within the range of 1 to 3 mm. When the thickness of the lower surface plate 1 is 3 mm or more, it is not preferable because the entire heat-generating floor plate becomes difficult to bend and it becomes difficult to deal with a step or unevenness generated in the floor base material.

As described above, since the base plate 1 of the heat generating floor plate is formed of the thermosetting resin-impregnated sheet, the thickness of the heat generating floor plate as a whole can be made smaller than that in the case of using the plywood lower plate. It is preferable in terms of workability and workability. or,
The thermosetting resin-impregnated sheet has better adhesiveness to vinyl acetate adhesives and other general-purpose adhesives for construction than resin plates such as metal plates and PVC, and has excellent adhesion durability with floor base panels. It was confirmed that it was equivalent to or better than the wood board.

The crosspiece 2 integrally bonded to the upper surfaces of both side ends of the lower plate 1 made of the thermosetting resin-impregnated sheet.
Is made of wood material such as plywood, particle board, MDF, and solid material, and the heat insulating material 3 disposed on the lower plate 1 between the crosspieces 2, 2 is an insulation board, glass wool, rock wool. ,Urethane foam,
A plate-like material such as foamed phenol or a single material or a composite of two or more kinds, which is reinforced with plywood or a net-like material as needed, is used. In addition, this heat insulating material 3
It may be adhered to the lower surface plate 1, but it is preferable that it is simply placed so as not to generate internal stress due to expansion and contraction.

As the heating element 4 laminated on the heat insulating material 3, a sheet heating element or a heating wire type heating element can be used, and a soaking plate 6 such as an appropriate metal plate is provided on the heating element 4. And a resin plate for leakage prevention are integrally laminated.
Further, the heating element 4 is equipped with a thermostat, a sensor, a wiring cord and the like. Note that the heat insulating material 3 and the heating element 4 may not be bonded.

The surface plate 5 which is in contact with the upper surface of the heat equalizing plate 6 on the heating element 4 and is fixed between the upper surfaces of the crosspieces 2 and 2 is a wood veneer or a wood veneer and is made of unsaturated polyester, acrylic or styrene. It is made of synthetic resin-injected wood veneer or plywood, which is made by injecting and solidifying synthetic resin liquid such as phenol, and in the case of wood veneer or synthetic resin-injected wood veneer, it has an appropriate thickness on its back surface. A wood base material made of a single material or a composite material such as plywood, MDF, and particle board is laminated to form a surface board having a thickness of 2 to 15 mm. The heating element 4 may be integrally bonded to the lower surface of the surface plate 5 via the soaking plate 6.

In the heat-generating floorboard thus constructed, the lower surface plate 1 is adhered to the underfloor panel 7 such as plywood, particle board and MDF with an appropriate adhesive 8 such as a vinyl acetate or epoxy adhesive. It is constructed by doing. At this time, since the lower surface plate 1 is made of a thin thermosetting resin-impregnated sheet having a thickness of 0.1 to 3 mm, even if the thickness of the entire heat-generating floor plate becomes thin and steps or minute uneven surfaces are generated on the floor base panel. Adhesion is good, and the thermosetting resin impregnated sheet acts as a barrier layer against moisture to prevent moisture from invading the inside of the heating floorboard, and to withstand long-term use without deteriorating the internal electrical components. Is something that can be done.

[0016]

As described above, according to the heat generating floor plate of the present invention, the wooden crosspieces are fixed in the longitudinal direction of both side ends on the upper surface of the rectangular lower plate made of the thermosetting resin impregnated sheet,
Since the heat insulating material and the heating element are laminated on the floor plate between these wooden beams, and the wooden surface plate is fixed to the upper surface of the wooden beam, the lower plate of the heating floor plate is thinly heat-cured. Since it is made of a resin-impregnated sheet,
Even if there are steps or minute uneven surfaces on the floor base panel,
The heat-generating floorboard can be closely fit along the surface, allowing accurate construction without warping or rising, and the thermosetting resin impregnated sheet, which is the bottom plate, can be used under the floor with ordinary adhesive. When bonded to the ground panel, reliable bonding can be performed without causing defective bonding unlike a metal plate or a synthetic resin plate.

Further, even if moisture enters from the back surface side of the floor base panel, the thermosetting resin-impregnated sheet serves as a barrier layer against moisture, and it is possible to reliably prevent the moisture from entering the inside of the heat-generating floorboard. It can be used for a long period of time without the risk of deteriorating internal electric parts and the like.
