[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water type floor heating panel and a manufacturing method thereof, and more particularly to a thin floor heating panel having a hot water passage formed in the panel itself and a manufacturing method thereof. .

[0002]

2. Description of the Related Art It is inconvenient to use a floor heating panel itself as a floor of a building when repairing the floor heating panel or when renovating a building. Since the method of laying floor heating panels on the original floor is adopted, there is no choice but to have a floor structure with a large thickness as a whole.

As shown in FIG. 7, a hot water type floor heating panel as a concrete example of this conventional floor heating panel has a heat insulating board 11 having a pipe recess 12 formed therein. A synthetic resin pipe or a metal pipe 13 as a hot water channel is fitted, and a thin box-shaped reinforcing soaking metal plate frame 14 capable of covering and fixing the pipe surface side and side face is fitted, and a heat insulating board An example in which a reinforcing plate 15 is arranged on the back surface side of 11 can be mentioned.

In this conventional floor heating panel, since the pipe is embedded as a hot water channel, the diameter of the pipe to be buried is small in order to secure the circulating hot water amount that maintains the performance of floor heating. Therefore, there is a limit to the thinning of the floor heating panel as a whole.
It was usual to be more than mm. Therefore, there is a problem that the floor becomes thick.

On the other hand, since the pipe is used, the contact between the upper panel and the pipe is linear, and the heat transfer effect of heating the floor through the panel is extremely low. Furthermore,
Since the connecting end of the pipe is provided along one of the sides of the rectangular panel or at the corner, depending on how the panels are spread or depending on the shape of the entire floor, the connecting end of the pipe to be connected For example, if they are separated from each other,
There was a problem in the efficiency of the pipe connection.

[0006]

Therefore, the object of the present invention is to solve the above-mentioned drawbacks of the conventional floor heating panel and to make the panel thin while ensuring a sufficient circulating hot water amount. It is an object of the present invention to provide a floor heating panel which has a large heat transfer effect and is convenient and easy to lay down the panel.

Still another object of the present invention is to provide a manufacturing method capable of easily manufacturing the thin floor heating panel as described above.

[0008]

As a result of intensive studies to solve the above problems, the present inventors have solved the problem by forming a special hot water passage in the panel itself without using a conventional hot water pipe.

(Seventh) A groove is formed in a meandering shape on the surface of the heat insulating material board, and a thin layer of a heat adhesive resin is laminated on the entire surface of the heat insulating material board to form a multilayer heat insulating material board, and then the heat adhesive property is formed. A heat-adhesive resin film is placed on the resin thin layer side by laminating and integrating a heat-adhesive resin film. A method for manufacturing a floor heating panel in which an adhesive resin film and a soaking metal plate are integrally bonded. (Eighth) Water-impermeable / adhesive synthetic resin heat insulating board is formed with meandering grooves on the surface thereof, and then a soaking metal plate is overlaid, and the synthetic resin heat insulating board and soaking metal A method for manufacturing a floor heating panel, which is integrally bonded to a plate. (Ninth) On the concave groove side of the surface of the heat insulating board made of synthetic resin, a soaking metal plate in which thermoadhesive resin films are laminated or integrated is placed, and thermocompression bonding is performed from the soaking metal plate side. The method for manufacturing a floor heating panel according to claim 8, wherein the synthetic resin heat insulating material board, the heat-adhesive resin film, and the soaking metal plate are integrally bonded.

The details of the present invention will be described below. The heat insulating board used in the present invention is provided with a concave groove for forming a hot water channel in a meandering shape on the surface thereof, and hot water of fairly high temperature is constantly flowed, but at that time, a material which is hard to be deformed by heating is used. Must be used. This is particularly necessary when the hot water channel is provided on only one side.

Further, since it is constantly in contact with hot water, if it has water permeability (including water absorption), it cannot fulfill its original function as a hot water channel. Therefore, if necessary, a synthetic resin thin layer having no water permeability is laminated on the hot water contact surface. Furthermore, since these heat insulation board and thin layer made of synthetic resin are usually in direct or indirect contact with hot water of 50 to 95 ° C. as a hot water channel, a material having high heat resistance is required, The resin thin layer is not peelable from the heat insulating material board based on the difference in expansion and contraction, high adhesiveness to the heat insulating material board, adhesiveness to a soaking metal plate or adhesive resin film described later, is required, Eventually, a thin adhesive resin layer having heat resistance is formed.

As a heat insulating material satisfying the above requirements, a wood insulating board is usually used in many cases, but a synthetic resin insulating board is preferably used in terms of water resistance and the like. Particleboard as wood material,
A veneer board is preferable, and as the synthetic resin material, polyethylene, expanded polyethylene, crosslinked polyethylene, crosslinked expanded polyethylene, polypropylene, expanded polypropylene, polybutene, polystyrene, expanded polystyrene, expanded polyethylene terephthalate, or the like is suitable.

In the case of the above wood material, the entire surface including the inner surface of the groove as described above has heat resistance, water and water vapor impermeable property, and adhesive property, in particular thermal adhesive property, so as not to come into direct contact with hot water. It is necessary to laminate a synthetic resin thin layer, and as the material of the thin layer, polyethylene, foamed polyethylene, crosslinked polyethylene, crosslinked foamed polyethylene, polypropylene, foamed polypropylene, polybutene, etc. are preferably used, but especially low crosslinked polyethylene or the like. Polybutene is preferred.

In the present invention, for the construction of the floor heating panel, a laminated structure of a plurality of layers having various functions is adopted.
Therefore, the plurality of layers must be bonded and integrated by various means. For fusion bonding and integration here, heat fusion is the simplest method between synthetic resins. Taking into consideration, simple heating, high frequency heating, ultrasonic heating, fusion by pressure heating, etc. are appropriately selected. Further, in the case of a metal plate and a synthetic resin, it is preferable to take a physical or chemical surface treatment method for imparting adhesiveness or heating to the metal plate, and for the synthetic resin, selection of a highly polar resin, A method such as chemical modification for imparting polarity is appropriately selected. In the case of the wood material and the synthetic resin, the above-mentioned selection of the synthetic resin can be directly applied and applied. Further, it goes without saying that a method of applying a specific adhesive between the laminated materials to bond and integrate them or a method based on a chemical reaction between the laminated materials can be appropriately used.

Adhesion for lamination used in the present invention includes fusion bonding integration of both materials, adhesion integration by melting only one, adhesion by a specific adhesive, and adhesion by chemical reaction under pressure. And the like (in the present invention, it is used in a broad sense unless otherwise specified), and various integrations in a narrow sense, that is, integration by heat bonding, fusion bonding, pressure bonding, chemical reaction, etc. is also included. Be done.

In the present invention, when the heat insulating material board itself has an adhesive property with a soaking metal flat plate, for example, it is made of a thermoplastic synthetic resin having an adhesive property with a metal as described above, or is impregnated with the resin. Other than wood material,
An adhesive resin thin layer and an adhesive resin film are used to bond and integrate both.

The recessed groove in the present invention preferably has a cross-sectional area and a cross-sectional shape that allow as much hot water as possible to flow after the hot water passage is formed, but the object of the present invention is to reduce the thickness of the panel. And the heat dissipation to the floor surface side is improved (heat dissipation to the inside of the floor is reduced as much as possible), and in terms of maintaining the strength of the panel, the V-shaped or U-shaped section with a low height is most preferable. Adopted. In addition, since the shoulder portion of the groove has an appropriate width, the adhesion area with the soaking metal plate described below can be widened, so that the sealed adhesive state can be favorably maintained, and the hot water passage without leakage can be provided. Can be secured.

By forming the hot water passage in a reciprocating manner, the temperature of the floor heating can be made uniform, so that the above-mentioned concave grooves are parallel to each other.
Articles are formed and become the forward and return routes, respectively. If only one panel is used, it is only necessary to connect the ends of the two recessed grooves, but if multiple panels are used, the pipes of adjacent panels can be connected to each other to cover a large area. It is possible to form a continuous outward path and a continuous path.

A metal plate which is a flat plate is brought into contact with the groove forming surface of the heat insulating material board, and the metal plate is joined to the heat insulating material board by heating from the flat plate side. In this joining, the metal plate can be heat-bonded to the heat insulation board by subjecting the metal plate to a surface treatment for adhesion or by interposing a synthetic resin film that thermally adheres to the adhesive resin thin layer on the heat insulation board side.

The interposing adhesive resin film is preferably the same as the synthetic resin heat insulating board or the same thin adhesive resin thin layer laminated on the surface of the wood heat insulating board.

The above-mentioned metal flat plate functions as a soaking metal plate which covers the concave groove to form a hot water channel, disperses the heat of the hot water widely, and heats the floor as uniformly as possible. The metal materials that can be used here include aluminum, copper,
Iron, stainless steel, tin alloys, zinc alloys and the like are preferably used for the purpose of the present invention and in terms of cost. The thickness of the soaking metal plate is not particularly limited, but it is not preferable that it is as thin as a foil because it is located at or near the floor surface, and normally a thickness of about 0.5 to 3 mm is preferable.

The above-mentioned panel according to the present invention is formed by forming a square for floor heating according to the present invention, forming notches at both corners of a diagonal line, and projecting pipes as terminal ends of the hot water passages at these portions. The panel is easier to use and has better workability. That is, when one panel is made into a square, many sides can be easily spread in a dense state because there is no length on each side, but when the corners do not come next to each other between adjacent panels, The hot water channel connection work between panels becomes complicated. However, if one of the adjacent panels is rotated by 90 degrees, the corners will easily come next to each other, and the hot water path between the panels can be connected at the shortest distance.

In addition, by fitting a square panel to the floor shape,
Not only in the case of squares but also in the case of arranging in various irregular shapes, the hot water channels can be connected in the shortest distance, which is efficient.

[0023]

The floor heating panel according to the present invention does not use a circular pipe, but has a wide mouth U-shape, a wide mouth V-shape, and other wide and shallow groove shapes, so that it is half or less of the conventional one. In addition, each panel has two concave hot water passages, and by connecting the hot water passages between the panels, a single or a plurality of forward and return paths that spread widely over the floor are formed.
Furthermore, by using a soaking metal plate, heat is spread widely not only on the hot water passage part but also on the floor, enabling direct heating with good heat transfer and heat dissipation effects and uniform floor heating. Also, by making the panel square and providing notches and hot water channel connection ends at each corner on a diagonal line, it is possible to freely spread the floor heating panel according to the present invention and to provide the shortest water channel connection. ing.
