DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel. More specifically, the present invention relates to a floor heating panel that is arranged between joists and has a small number of steps and is easy to perform when a floor heating panel is actually constructed.

[0002]

2. Description of the Related Art Conventionally, floor heating technology for heating from the floor of a house has been proposed and put into practical use for the purpose of improving the livability of a house in a cold season. For example, when installing floor heating equipment in a floor framing method using the bundled floor framing method, first place a slab stone on the ground, bundle it on it, hand over it, and then put a plurality of Are placed at regular intervals, and a floorboard is put on the joists to form a floor set. In order to incorporate the floor heating panel into this floor group, the vertical direction is the middle between the upper side of the deck and the bottom of the floorboard, and the horizontal direction is between adjacent joists, A method of arranging the joists between adjacent joists by using a hanger is adopted (for example, Japanese Utility Model
3-139110).

[0003]

As a floor heating panel, a long plate-shaped molded article made of a foamed resin is used as a base, and a groove of a heating fluid conducting tube is formed on one surface of the base. A structure in which a conduit for heating fluid is buried in a groove and the surface thereof is covered with a surface material such as aluminum foil has been proposed (for example, see Japanese Utility Model Application Laid-Open No. 2-67808). In order to construct a floor heating panel having such a structure, first, a fastener such as that described in Japanese Utility Model Application Laid-Open No. 53-139110 is arranged on a joist at the construction site, and then a floor heating panel is arranged. Finally, it is necessary to carry out three steps of straddling both the hanging member and the floor heating panel and bonding with an adhesive tape made of a thin metal plate, and from the viewpoint of the installer, there are still many steps. There were drawbacks.

[0004] Under these circumstances, the present inventors have conducted intensive studies to provide a floor heating panel that eliminates the disadvantages of the conventional method, and as a result, have completed the present invention.
The present invention aims at the following. 1. A floor heating panel is provided between joists. 2. To provide a floor heating panel that can be constructed with a small number of work steps when the floor heating panel is constructed.

[0005]

In order to solve the above-mentioned problems, in the present invention, a long plate-like molded article made of a foamed resin is used as a base, and a heating fluid is provided on one surface of the base along a longitudinal direction. A floor heating panel formed by engraving a groove of a conduit for use in heating, and a conduit for heating fluid being buried in the groove, wherein both sides along the length direction of the base are perpendicular to the longitudinal direction. A panel for floor heating characterized by being provided with a hook having a Z-shaped cross section and an inverted Z-shaped cross section when cut.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The floor heating panel according to the present invention is based on a long plate-shaped molded product made of a foamed resin. Examples of the material resin constituting the base include hard general-purpose resins such as polystyrene, polyethylene, polypropylene, and polyvinyl chloride which form closed cells when forming a foamed plate-like molded product. Above all, polystyrene is excellent in heat insulation because the foam molded body is closed cells, it is difficult to dissipate the heat of the heating fluid, and it is excellent in rigidity despite its light weight, so it is placed between joists. Is also difficult to bend, which is particularly preferable. The thickness of the substrate can be selected in the range of 30 to 50 mm depending on the height of the joist, 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.

The base is disposed between floor joists (the width of the joists themselves is about 35 to 45 mm) as a floor heating panel.
Its width is smaller than the interval between adjacent joists 303 mm or 455 mm, for example, 253 mm or 405 mm. Further, it is preferable that the floor heating panel is provided with cuts perpendicular to the length direction for each desired length of the base. Here, the cut means that the base is completely cut at a right angle to the length direction, and the length of one unit providing the cut is 700 mm, 910 mm from the viewpoint of packing, workability, and the like. (Half), 1365mm, 182
The length is selected to be 1820 mm (one interval) or less, such as 0 mm (one interval).

In the base, a plurality of grooves of the conduit for the heating fluid are formed on one surface thereof along the longitudinal direction. This groove serves to bury the heating fluid conduit. The width of the opening of the groove is determined by the outer diameter of the heating fluid conduit (for example, 8.
5 mm) or preferably slightly larger. When the shape of the groove is such that the cross section when cut at a right angle in the length direction forms a U-shape, it is convenient when the conductive tube is buried.

The depth of the groove is determined by the outer diameter of the conduit (for example, 8.5 m).
It is preferable that the thickness is the same as m) and that the dimension up to the bottom surface of the groove does not exceed 50% of the thickness of the substrate. If the depth of the groove is larger than the outer diameter of the conduit, there will be a gap above the conduit when the conduit is buried in the groove, and the heat of the heating fluid cannot be transferred effectively to the surface material. In addition, the heat transfer efficiency of the floor heating panel decreases, which is not preferable. If the bottom surface of the groove exceeds 50% of the thickness of the base, the bottom wall surface of the groove becomes too thin, and the strength of the base and the heat insulating property of the base may decrease, which is not preferable.

[0010] The floor heating panel has a heating fluid conducting tube buried in a groove formed on one surface of the base, and the upper surface thereof is covered with a surface material. The heating fluid conducting pipe is made of, for example, a cross-linked polyethylene pipe, a polybutene pipe, or the like, and its diameter varies depending on 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 8.5 mm and an inner diameter of 6 mm is generally used. The surface material has a function of radiating heat of the heating fluid passed through the conduit to the floor plate. Examples of the heat medium passed through the floor heating panel include hot water, steam, and heating oil.

[0011] The floor heating panel according to the present invention has a hook having a Z-shaped cross section and an inverted Z-shaped cross section when cut at a right angle in the length direction on both side portions along the length direction of the base. Is attached. The latch has a function of locking a floor heating panel between adjacent joists and closing a gap that may occur between the joists and the base depending on the width of the joists themselves and / or the width of the base itself. Fulfill. That is, the upper surface of the hanging member having a Z-shaped or inverted Z-shaped cross section is placed on the upper surface of the joist, the lower surface of the hanging member supports the bottom wall surface of the base, and the width of the joist and the width of the base. Thus, a gap that may occur between the joist and the base can be closed by the upper surface and the lower surface of the hook.

The latch having a Z-shaped cross section and an inverted Z-shaped cross section may be made of metal or synthetic resin having excellent rigidity. If the material of the latch is synthetic resin,
It can be easily manufactured by an extrusion molding method. The latch is
Attached to both sides along the length of the base.
To attach the hook to the side of the base, the bent portion where the hanging part starts from the top of the hook is brought into contact with the side of the base, and both the surface of the base and the top of the hook are attached. What is necessary is just to bond over with the adhesive tape made from a thin metal plate over the span. When the hook is attached, it may be attached over the entire length in the length direction of the base, or for example, the length of one hook may be 2 to 10
It may be 0 cm and a plurality of them may be attached at intervals of 50 cm or less.

[0013] By slightly changing the structure of the hook, the attachment of the hook to the side surface of the base can be further ensured. An example of the modification is that a hook having a Z-shaped cross section and an inverted Z-shaped cross section when cut at a right angle in the length direction is provided so that an upper surface portion extends outward in parallel with the floor heating panel,
The hanging part is provided at an angle of 5 ° or more with respect to a vertical line from the top part to the upper part side, and a lower part connected to the hanging part is provided, but the bent part where the lower part starts is the lowest part, The structure is such that it extends upward as the distance from the bent portion increases. By making the tip direction of the lower surface part upward, the base body can be urged upward and can be in close contact with the floor plate. Thereby, the heat conduction effect of the floor heating panel can be further improved.

Another example of the deformation is that the hanging portion is provided vertically from the upper surface portion, and the lower surface portion connected to the hanging portion is a bent portion where the lower surface portion starts at the lowermost portion. The structure is such that it extends upward as it moves away from the bent portion. Thereby, the base can be urged upward and can be brought into close contact with the floor plate, so that the heat conduction effect of the floor heating panel can be further improved.

Still another example of the modification is that, in addition to the above-exemplified latching tool, a latching tool having a Z-shaped cross section and an inverted Z-shaped cross section cut at a right angle in the length direction is provided. This is a structure in which an insertion portion protruding in a direction opposite to a direction in which the upper surface portion extends is provided at a position slightly below the extension position. The insertion portion can stabilize the attachment of the hook to the base by piercing the side surface along the length direction of the base. The length of the insertion portion may be equal to or slightly shorter than the length of the extended upper surface portion.

Further, in order to ensure the attachment of the hook to the side surface of the base, the hook of any structure is used to connect the surface of the base to the upper surface of the hook. It is preferable that both sides are adhered with an adhesive tape. Examples of the type of the metal sheet of the metal sheet adhesive tape include aluminum foil, tin foil, and 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 metal thin plate is too small, the strength is not sufficient, and if the thickness is too large, the cost of the product is high.

The floor heating panel according to the present invention is as described above, and is a floor set using a joist, for example, a floor set by a bundling method, a floor set by a two-by-fore floor setting method,
The present invention can be applied to a floor set by a beam floor set method and the like. The present invention can be applied not only to a case where a building is newly built but also to a case where a building is remodeled.
