Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a base material for floor heating, and particularly to a block-shaped base plate for floor heating having a built-in surface heating element function.

[Conventional technology]

[Problem that the invention seeks to solve]

In floor heating base plates having this type of structure, the former has disadvantages in that the synthetic resin foam deteriorates due to heat and the plywood deforms significantly due to heat after long-term use. Moreover, in addition to the above-mentioned drawbacks, the latter often suffers from breakdowns due to disconnection, and has various practical disadvantages.

Means for Solving Problem c] In order to eliminate such drawbacks, the present invention lays a large number of particles that will become the elements of the surface heating section on a noncombustible board that does not change in size and has heat insulation properties, and The voids between these particles are filled with a conductor, and the surface layer is an insulator layer or 'ff1t
The structure is such that it is covered with an A edge plate and an electrode is provided on the heat generating surface made up of the large number of particles.

[For production]

In the present invention, a non-combustible board with inorganic heat insulating properties that does not undergo dimensional deformation and is rich in fire retardant properties is provided on the necessary portions of the floor, and the heat-resisting particle body (planar heat-generating A surface heating section is formed by laying the particles at a desired density, and the gaps between the particles are filled with a conductor, and the particles are fixed in a buried state to provide electrical continuity between the particles. The surface layer of the underfloor heating base plate is filled with an insulator, such as synthetic resin, concrete, polymer concrete, rock wool, or slate, so any area can be heated to any temperature. In addition, it is thermally efficient and can retain heat for a long time, has low heat conduction to the underfloor, and has no dimensional change, making it extremely safe and durable.
Furthermore, even if water or the like leaks onto the floor, the performance will not be adversely affected in any way.

Reference numeral 1 denotes a planar heating section in which thermal resistance particles i (hereinafter simply referred to as heating particles) are dispersed and laminated in one layer, a plurality of layers, or randomly distributed layers.

To explain further, the exothermic particles ↓ are a type of granular particles with a particle size of 1 to 300 mesosci or more, for example, 3 to 10 φ, consisting of particles 5 that become the core body of sand, gravel, obsidian, gemstones, rocks, etc. It consists of the above, and its outer surface is coated with a coating film (hereinafter simply referred to as coating film) made of a conductive paint. In particular, it is preferable that the coating film be baked. In addition,
The conductive paint may be a conductive polymer, or as shown enlarged in FIG. 3, a conductor 7 such as nickel powder, copper powder, silver powder, etc. and a binder 8 made of acrylic resin or the like. and an electric resistor 9 made of one or more of carbon black and nichrome cotton powder. Note that the ratio of conductor 7 to binder 8 is 8.
0%: 20%, the electrical resistor 9 is added in an amount corresponding to the required temperature. ■ is an electrical conductor layer (hereinafter simply referred to as a conductor layer), which is used as an adhesive to fix the heat-generating particle soil to the noncombustible board 2, a filler to fill the void between the heat-generating particle soil, a heat-resistant material, a thermal conductor, and a reinforcing material. Dense body, low foam material (4

More specifically, the conductor layer is made of the same material as the conductive paint, such as one or more of conductive polymer resin, conductive resin, polymer cement containing paint, resin concrete, and the like. Reference numeral 11 denotes a decorative layer, which is a conductor layer, and is made of one type of insulator laid or formed on the surface of the conductor, such as synthetic resin (polyurethane, phenol, polyethylene),
It consists of one or more of slate, calcium carbonate, calcium silicate, cement, mortar, insulating polymer cement-insulating resin concrete, concrete (for finishes without aggregate), rock wool, clay, etc. 1
Reference numeral 2 denotes an electrode for supplying power to the heat-generating particle soil, which is optionally provided at both ends or one end of the board, the bottom surface, etc.

Next, a construction example will be explained. Assume now that the board shown in Figure 1 is to be installed on a wooden base floor only in the necessary areas on the floor using the conventional construction method. The navigator and other floor parts have been constructed using other materials or cement mortar so that they are flush with the top of the board.

Therefore, a noncombustible board 2 was placed on the joist A or on the roofing board B.
Heat generating particles i (particle size 3 lψ) are laid on top to form the main surface heating section, and a conductor layer U (20% acrylic resin, 80% nickel powder) is buried on top of the heat generating particles ↓. Simply fill it with slate, place a slate board (thickness 5 dragons) on top of it, place the board that has been made into a slate, and then lay a rug C1, such as a rug C1 floor, carpet, etc. This completes the heated floor. Note that the electrode 12 is simply connected to an electric wire that is routed under the floor or on the board to the point where it is to be installed. Further, in FIG. 4, D indicates a case where a moisture-proof sheet is laid on the roofing board B as necessary.

〔Effect of the invention〕

As mentioned above, according to the floor heating base plate according to the present invention,
■There is no dimensional change, and it is stable and safe over a long period of time. (2) Since the surface heating part is formed of a large number of heat generating particles, even if a part of the heating element is broken, the surface heating part will not be cut or a failure (power outage) will not occur over the entire area. ■A noncombustible board is formed with a highly heat-insulating layer, and a large number of heat-generating particles are laid down, and a ring is filled between the particles as a binder and finishing material,
Manufacturing is simple, as it is only necessary to place a decorative board on top of it. ■Since the board is strong, it can be installed directly on a slab or joist, and by simply laying a rug over it, it can be easily used for new or refurbished heated floors.

It has the following characteristics.
