2. Description of the Related Art As a heating floor structure, Japanese Patent Laid-Open Publication No.
Japanese Unexamined Patent Publication No. 4 (KOKAI) No. 4 is conventionally known. In this heating floor structure, a wooden base panel formed by arranging and fixing a plurality of band-shaped plates in parallel at predetermined intervals on the upper surface of a flat plate on a flat floor base is installed, and adjacent band-shaped A hot water flow pipe is accommodated in a groove formed between the boards, and a plurality of wooden floors are laid on the upper surface of the base panel via a metal plate.

As a heating floor structure, Japanese Patent Application Laid-Open No.
The one disclosed in Japanese Patent No. 2236 is also conventionally known. In this heating floor structure, a plurality of hot water circulation pipe housing groove forming units each formed of a pair of rods arranged in parallel with a required gap are provided in parallel on a flat floor base at predetermined intervals. In addition, a heat insulating material is interposed between the adjacent units, and the hot water flowing pipe receiving groove formed by the unit and the flat floor base is inserted through a metal plate having a concave portion fitted into the groove. A flow pipe is accommodated, and a floor finishing material is laid on the upper surfaces of the unit and the heat insulating material.

[0004]

However, the above two conventional heating floor structures have the following problems, respectively.

That is, since the two-floor heating structure is formed by sequentially applying each floor material at the building site as described above, it takes a lot of time and labor and is extremely inferior in work efficiency.

[0006] In the case of a double-floor heating structure, dust may accumulate in the hot water flow pipe accommodating groove during the installation work of the hot water flow pipe.
The groove was sometimes scratched. Moreover, since the hot water flow pipe provided in the hot water flow pipe accommodating groove is exposed, there is a possibility that the hot water flow pipe may be damaged during the subsequent work. Therefore, in order to cope with such a problem, in the conventional construction of the two heating floors, even if it is troublesome, the plywood or the plywood is placed on the installed base panel, the hot water circulation pipe housing groove forming unit and the heat insulating material. Sheets and the like were discarded and pasted.

In the heating floor structure disclosed in Japanese Patent Application Laid-Open No. Hei 8-21074, the metal plate interposed between the base panel and the wooden flooring contributes to the improvement of heat uniformity. A 0.335 mm or 0.6 mm zinc iron plate, aluminum plate, or the like has been used. This metal plate is usually fixed to the base panel together with the wooden floor by nails that are driven into the real part of the wooden floor from diagonally from above.However, the nails are slid and driven into the metal plate because they are harder and more smooth than wooden floors It was difficult. Also, due to the difference in hardness between the wooden floor and the metal plate, when the nails driven into them reach the metal plate, they decelerate momentarily, and the wooden floor rises toward the nail head due to the reaction, and the nail is driven as it is. In some cases, the wooden flooring was raised from the base panel.

[0008] An object of the present invention is to solve the above problems.

[0009]

A heating floor panel according to the present invention comprises a wooden board having a groove in which a hot water flow pipe is accommodated on a lower surface, and a backing sheet joined to the lower surface of the wooden board so as to close the groove. It is provided with.

In the heating floor panel according to the present invention, preferably, a soaking sheet is joined to an upper surface of the wooden board.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings.

1 to 4 show the structure of a panel for a heating floor according to the present invention. This heating floor panel (1) is a wooden board having a groove (21) on its lower surface in which a hot water distribution pipe (3) is accommodated.
(2), a backing sheet (4) joined to the lower surface of the wood board (2) so as to close the groove (21), and a heat equalizing sheet (5) joined to the upper face of the wood board (2). Consisting of

The wood board (2) is made of wood fiber board such as plywood, medium fiber board (MDF), hard fiber board (HB), high specific gravity wood fiber board (HDF), particle board, oriented strand board. , A laminated board, a laminated wood and the like can be appropriately selected, a single type may be used, or a combination of several types may be used. From the viewpoint of nail holding power, plywood, medium fiber board, high specific gravity wood fiber board, laminated board or laminated wood is preferable as the material of the wood board (2). Also, dimensional stability, ie,
Plywood is preferred from the viewpoint that the dimensional change due to moisture absorption and desorption is small, and from the viewpoint of workability and homogeneity,
Wood fiberboard is preferred. Naturally, the thickness of the wooden board (2) must be larger than the depth of the groove (21) formed on the lower surface of the wooden board (2), but the thickness above the groove (21) will not be damaged during handling. You need to do that. When the wood board (2) is made of plywood, it is preferable that a portion of the wood board (2) above the groove (21) is constituted by two or more layers of veneers whose fiber directions intersect each other. ,panel
(1) Damage to the hot water distribution pipe (3) during construction can be more reliably prevented.

As a material of the hot water distribution pipe (3), for example,
Examples thereof include metal pipes such as copper and iron, and flexible synthetic resin pipes such as a cross-linked polyethylene resin. However, from the viewpoint of the connectivity between the pipes, a synthetic resin pipe which is rich in flexibility and can be easily connected by, for example, a bamboo shoot joint and a pipe band is preferable.

The groove (21) on the lower surface of the wooden board (2) is appropriately formed by a router or the like according to the size, number, and piping pattern of the hot water flow pipes (3) to be accommodated. The depth and width of the groove (21) are determined in consideration of the radial and longitudinal expansion due to water flow through the hot water flow pipe (3),
It is set slightly larger than the outer diameter of. For example, when a flexible pipe such as a cross-linked polyethylene resin pipe is used as the hot water distribution pipe (3), the depth of the groove (21) is about 0.2 mm compared to the outer diameter of the pipe when the water is not passed. 0.5mm width
Set each level to be large. However, from the viewpoint of thermal conductivity, it is preferable that the hot water flow pipe (3) and the bottom of the groove (21) are always in contact with each other, and for this purpose, a flexible pipe is used as the hot water flow pipe (3). The depth of the groove (21) is the same as the outer diameter of the hot water flow pipe (3) when water is not flowing, and the width of the groove (21) is larger than the outer diameter of the hot water flow pipe (3) when water is not flowing. It may be slightly larger. In this way, the hot water flow pipe (3) and the groove (21)
In addition to being in contact with the bottom surface, the expansion of the hot water flow pipe (3) during water flow is received in the gap between both sides of the groove (21). In order to connect both ends of the hot water distribution pipe (3) to the ends of the hot water distribution pipe (3) of the adjacent panel (1), grooves on the bottom of the wooden board (2)
Both ends of (21) are open to the side (see FIG. 1). As shown in FIGS. 1 and 3, the hot water flow pipe (3) is usually provided in a meandering shape as viewed from a plane, but may be provided in a spiral shape or the like, and may be set arbitrarily. . In addition, in the panel (1) shown in FIGS. 1 and 3, the hot water distribution pipe (3) is piped slightly to one short side of the wooden board (2). It is set appropriately according to the position of the occupied panel, etc.
Some panels are provided with hot water flow pipes (3) almost all over (2), but they are even more deviated to one short side than the wood board (2) shown in FIGS. 1 and 3, or one long side. Hot water distribution pipe
(3) Some panels have piping.

The backing sheet (4) is joined to the lower surface of the wooden board (2) to prevent the hot water distribution pipe (3) from falling off from the groove (21) and to prevent the hot water flow pipe (3) from dropping during manufacturing or construction. Damage to the hot water flow pipe (3) during handling is prevented. Backing sheet
Examples of the material (4) include paper, nonwoven fabric, moisture-proof sheet, open-cell or closed-cell foam sheet, etc., of which a single type may be used or a composite sheet combining several types. May be used, but preferably a moisture-proof sheet is used. If the backing sheet (4) is made of a moisture-proof sheet, it will absorb moisture to the wooden board (2) in combination with a heat equalizing sheet (5) made of a moisture-proof metal sheet as described later. Can be suppressed from both upper and lower sides, thereby preventing the warp of the wooden board (2). Since the independently foamed foam sheet also has moisture-proof properties, the same effect as described above can be obtained when this is used as the backing sheet (4). As a specific example of the moisture-proof sheet,
Examples thereof include a metal sheet, moisture-proof coated paper, a synthetic resin sheet such as polyethylene or polypropylene, a composite sheet in which paper or a nonwoven fabric is laminated on at least one surface of a metal sheet, a synthetic resin layer, or a synthetic resin sheet. When the backing sheet (4) is made of paper, nonwoven fabric, or a composite sheet having a paper layer or nonwoven fabric layer on the uppermost layer, adhesion to the lower surface of the wooden board (2) is easy. When the backing sheet (4) is made of paper, nonwoven fabric or a composite sheet having a paper layer or nonwoven fabric layer at the bottom layer, the panel (1) or the wood board (2) and the backing sheet (4) are formed during the manufacturing process. ) Has the advantage that it is not slippery even if it is deposited. Backing sheet (4)
Is composed of a metal sheet or a composite sheet having a metal sheet layer, the heat transfer efficiency can be improved by heat reflection upward of the sheet. Also, backing sheet
When (4) is composed of a foam sheet, a nonwoven fabric, or a composite sheet having these layers, even if the flat floor substrate on which the panel (1) is constructed has irregularities, it can be absorbed.

The soaking sheet (5) contributes to the improvement of the soaking property. Usually, a metal sheet such as an aluminum sheet or an iron sheet having a thickness of 0.3 mm or less is used, but at least one side of the metal sheet is used. A composite sheet in which paper or nonwoven fabric is laminated may be used. When the heat equalizing sheet (5) is made of metal sheet, if the thickness exceeds 0.3 mm, the heat uniformity is further improved, but the weight of the panel (1) increases, and nails for stopping the floor finishing material are used. Kind of permeability decreases,
When it is necessary to cut a part of the panel (1) at a building site, the cutting operation becomes difficult, and the cutting saw or circular saw blade becomes worn out. Also, heat equalizing sheet
When (5) is made of a metal sheet, if the thickness is 0.04 mm or more, it is unlikely to be wrinkled when bonded to the wooden board (2), and if the thickness is 1 mm or less, the panel (1) is used as a flat floor substrate. It is easy to fix vertically with nails. Considering the workability of bonding work with wood board (2), handling work, etc., heat uniformity and penetration of nails, heat equalizing sheet made of metal sheet
The thickness of (5) is preferably in the range of 0.04 mm to 0.55 mm. When the heat equalizing sheet is a composite sheet of a metal sheet and paper, it is preferable that the thickness of the metal sheet layer be the same as described above. The soaking sheet (5) is a wooden board
It is usually fixed to the upper surface of (2) by adhesion. Therefore, when the nails for stopping the floor covering are driven into the panel (1) from obliquely above, the heat equalizing sheet (5) does not move, and the floor covering does not stay in a floating state. Also, even when it is necessary to cut a part of the panel (1), the cutting work is easier than cutting the metal plate alone, because the heat equalizing sheet (5) is integrated with other panel materials. It is easy and does not cut your hands and fingers with the soaking sheet (5) during handling. As shown in FIG. 3, the heat equalizing sheet (5)
On the upper surface of the display, a display section (51) that clearly shows the location of the hot water distribution pipe (3) and indicates the places where nails can be driven or nailed
Is preferably formed by screen printing or the like. Note that the heating floor panel of the present invention also includes a panel without a soaking sheet, in which case, for example, a soaking sheet such as a soaking sheet is previously provided on the lower surface of the floor finishing material to be installed on the panel. May be joined, and at the time of construction,
A heat equalizing sheet may be joined to the upper surface of the wooden board (2) of the panel (1).

As shown in detail in FIG. 4, the groove of the wooden board (2)
(21) Hot water flow pipe in upper part and soaking sheet (5)
Notches (6) are formed at locations corresponding to both ends of (3) so as to be continuous with the groove (21). There is a step (61) near the upper edge of the notch (6), and a detachable lid (7) is fitted in the notch (6) so as to be placed on the step (61). By removing the lid (7) fitted in the notch (6),
Since both ends of the hot water flow pipe (3) can be exposed, for example, a bamboo shoot joint and a pipe band (not shown)
The connection operation can be easily performed by using. When the connection of the hot water distribution pipe (3) is completed, the lid (7) is again fitted into the notch (6), and a metal tape or the like may be attached and fixed. There is no danger that the hot water flow pipe (3) will be damaged during the subsequent work due to the coating. The lid (7) is made of a metal plate such as an aluminum plate having excellent thermal conductivity. In addition,
The notch (6) may be set to any length that facilitates the connection work between the hot water distribution pipes (3). In addition, the notch (6) and the groove (21) corresponding to the connection of the hot water flow pipe (3)
May be larger than the width of other parts.
