2. Description of the Related Art Conventionally, in order to improve the livability of a house in a cold region and the livability of a house in a warm region in a cold season,
Floor heating technology for heating from the floor of a house has been proposed and put into practical use. For example, in a detached house, a method of incorporating a floor heating panel on a plywood base laid on the deck between the daiki and the floorboard has been adopted, and in an apartment house such as an apartment, A method of directly laying a floor heating panel on a slab floor surface, on a base plywood laid on the slab floor surface, or the like is adopted.

[0003] The floor heating panel is, for example, made of a long plate-shaped molded body made of foamed resin, and a groove is formed on one surface of the long plate-shaped substrate, and a conduction pipe for a heating fluid is formed in this groove. A structure in which a “conducting tube” may be simply buried and its surface is covered with a surface material such as aluminum foil has been proposed. In addition, a hard material such as a hard resin foam is used as a base, a groove is formed on one surface of the base, and a conduction pipe for a heating fluid is buried in the groove, and the surface is made of a surface material such as aluminum foil. Coated structures have also been proposed. In order to construct a floor heating panel with such a structure, at a factory, in a groove engraved on one surface of a long plate-shaped molded body made of foamed resin,
Prepare in advance the arrangement of the conduit for the heating fluid,
A method is adopted in which the floor heating panel is transported and carried into a construction site and laid.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
The base material of the foldable floor heating panel according to the present invention is selected from resin foam, wooden plywood and the like. Resin foams include rigid polyurethane foams such as rigid polyurethane foams, polystyrene foams, crosslinked polyethylene foams, polypropylene foams, polyvinyl chloride foams, crosslinked rubber foams, and thermosetting resin foams. And low rigidity foams such as non-crosslinked polyethylene foams, polyvinyl acetate foams, non-crosslinked rubber foams, and foams of a mixture of high density polyethylene and polystyrene. The thickness of the substrate can be selected in the range of 8 to 30 mm, depending on the place where the floor heating panel is laid, and the expansion ratio can be selected in the range of 2 to 90 times, depending on the type of the resin and the thickness of the substrate. .

In the case where a wooden support is arranged in a floor heating panel, the width of the base is no greater than the interval between adjacent joists 303 mm or 455 mm regardless of the material of the base. Small, eg 258mm or 41
0 mm. When the base of the floor heating panel is a soft resin foam, one or more wooden supports are preferably arranged at regular intervals between the joists. Are selected in accordance with the intervals at which are arranged. The floor heating panel is laid on a base plywood placed on a slab floor, on a slab floor, on a base plywood laid on a slab floor, and the base is made of a soft resin. In the case of a foam, it is preferable to dispose the wooden supports at regular intervals in the length direction of the base because deformation of the base of the soft resin foam can be prevented.

When the substrate is made of a hard resin foam or a wooden plywood, the width of the substrate is, for example, from 303 mm to 1820 mm from the viewpoints of packing, storage, transportation, workability, etc. since a wooden support is unnecessary. It is selected with a width of 1820 mm or less. The width of the substrate may be the size of the single substrate, or may be the size of a combination of two or more substrates. The length of the substrate depends on packing, storage, transportation,
From the viewpoint of workability and the like, it is preferable to select a length of 3640 mm or less.

The base has a plurality of grooves formed on one surface thereof along the length direction. A heating fluid conduit is buried in this groove. The width of the opening of the groove is preferably the same as or slightly larger than the outer diameter (for example, 7.2 mm) of the conduit for heating fluid. The shape of the groove is convenient when the conductive tube is buried if the cross section cut at a right angle to the length direction forms a U-shape. Preferably, the depth of the groove is the same as the outer diameter of the conduit (eg, 7.2 mm). If the depth of the groove is larger than the outer diameter of the conduit,
When the conduit is buried in the groove, a gap is formed at the top of the conduit,
The heat of the heating fluid cannot be effectively transferred to the surface material, and the heat transfer efficiency of the floor heating panel decreases, which is not preferable.

The foldable floor heating panel according to the present invention has at least two of the above-mentioned substrates, a wooden support placed between the two substrates in a state where the upper ends of the substrates are in contact with each other, or between the substrates. In this state, most of the upper surface is covered with a surface material made of a thin metal plate. The surface material is preferably made of a thin metal plate, and the types thereof are aluminum foil, tin foil,
Examples include stainless steel foil. Among them, aluminum foil is particularly preferable from the viewpoints of production difficulty, cost, and the like. If the thickness of the thin metal plate is too thin, the strength is not sufficient. If the thickness is too thick, not only the weight of the product increases, but also the cost of the product increases. Therefore, it is preferable to select the thickness in the range of 10 to 500 μm. When separately preparing the center fitting portion and the end fitting portion, they are separately prepared and then separately attached with a surface material.

The floor heating panel which can be folded in the length direction has a central fitting portion which can be attached and detached at right angles to the length direction and over the entire width of the base so as to substantially divide the length of the base into two. It is provided. The base constituting the floor heating panel is manufactured in advance in accordance with the design drawing, and the center fitting portion is also manufactured in accordance with the design drawing. These can be prepared by integrally forming, engraving a plurality of grooves on the top surface, applying a thin metal sheet surface material, and then cutting. When a wooden support is arranged between the two substrates, it is preferable to cut at the center in the width direction of the center fitting portion.

[0015] With the central fitting portion attached to the base, a heating fluid conduit is buried in the groove. If the length of the central fitting portion (the length of the cut portion in the length direction of the base, which means a in FIG. 1) is too small, a group of heating fluid conducting tubes will collapse (buckling) when folded. Therefore, it is preferable that the length is set so as not to cause crushing (buckling). Although it depends on the length of the base constituting the floor heating panel, 20 to 80
It is preferable to select in the range of cm.

After the conductive tube for the heating fluid is buried in the groove and the central fitting portion is removed from the base, the conductive tube for the heating fluid is exposed at the substantially central portion in the longitudinal direction of the base over the entire width.
When a wooden support is placed between the substrates, the wooden support is also exposed at the same time, and the substrate is almost bisected in the length direction. In the portion where the heating fluid conducting tube is exposed, the base can be folded with the back surfaces of the substrates facing each other or with the surfaces on which the surface material is applied facing each other.

In order to form a floor heating panel which can be folded in the length direction and the width direction, the base is provided with the center fitting portion and the end fitting portion is provided as described above. The place where the end fitting portion is provided is one end in the longitudinal direction of the two bases on which the separable folds are formed, and is cut into substantially equal widths with the extension of the folds interposed therebetween. The length of the end fitting portion (the length of the cut portion in the length direction of the base, and FIG.
Means), even if the substrate is made of a hard resin foam or a wooden plywood, even if it is made of a soft resin foam,
It is preferable to select a length that allows a group of heating fluid conduits to be folded. Although it depends on the length of the base constituting the floor heating panel, it is preferable to select from 10 to 50 cm.

The end fitting portion is removed when the floor heating panel is folded, and is laid at the same time as the base when laying the floor heating panel. The end fitting portion functions as a radiator by burying a heating fluid conducting tube. The groove for embedding the conductive tube formed in the end fitting portion is connected to the groove of the base, and is formed by bending around the tip of the folded portion of the base on the fitting portion side. By engraving the groove in this manner, the conductive tube embedded in the base can be buried continuously in the groove of the end fitting portion without cutting the groove when the floor heating panel is laid.
The end fitting portion may be cut out after being manufactured integrally with another portion of the floor heating panel, or may be manufactured separately from the other portion. It is preferable that the groove of the end fitting portion be curved around the tip of the separable folding portion of the base on the side of the end fitting portion, but it is not necessary that the groove be completely concentric. Of course, you can.

When the floor heating panel according to the present invention is folded, a center fitting portion, a center fitting portion, an end fitting portion, and the like are used for a floor heating panel that can be folded in the length and width directions from the base. Is removed, and the foldable portion that can be separated is removed from the base and folded, and the base is overlaid. When folded and superimposed, the heating fluid conducting tube embedded in the groove does not come off the groove in the base portion covered by the surface material, and the heating fluid conducting tube is removed in the part where the fitting portion is removed. Although several are exposed,
There is no fear of the conduit being entangled between the bases and being crushed by being pinched between the bases, so that there is no hindrance during packing and unpacking, and work can be performed smoothly when laying floor heating panels. be able to.

In order to improve the heat radiation of the foldable floor heating panel, the upper surface of the central fitting portion and the end fitting portion is covered with a thin metal sheet material. When sticking a metal sheet to the groove where you bury the
The heat radiation efficiency can be further improved, which is preferable.

The heating fluid conducting pipe is made of, for example, a cross-linked polyethylene pipe, polybutene pipe, or the like, and its diameter is determined by the location of the building where the floor heating panel is installed, the thickness of the panel base, the type of the heating fluid, the temperature, and the like. Usually, a tube having an outer diameter of 7.2 mm and an inner diameter of 5 mm is generally used.
Examples of the heat medium that passes through the floor heating panel include hot water, steam, heating oil, and antifreeze oil (such as ethylene glycol and propylene glycol).

When the folded floor heating panel is laid, the folded state of the floor heating panel is released, and the floor heating panel with the fitting portion removed is laid in a predetermined place, and the exposed heating panel is exposed. What is necessary is just to arrange | position a fitting part on the lower side of the fluid conduit, to fit it in a base | substrate, and just fit and attach a conduit to the groove | channel of these fitting parts. When the floor heating panel is laid, the fitting portion may be fitted in a predetermined place of the base in advance, and the conductive tube may be fitted in the groove of the fitting portion, and then laid.

The floor heating panel according to the present invention is as described above. The floor heating panel uses a joist floor, the bundling floor, the two-by-for floor flooring, and the beam floor mounting method. The present invention can be applied to, for example, a slab floor, a base plywood laid on a slab floor, and the like. The building can be applied not only to a new building but also to a remodeling.
