Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure for floor heating, particularly to a floor for floor heating using hot water, and to a structure of a base panel suitable for this.

[0002]

2. Description of the Related Art Floor heating using hot water is energy saving,
Since it has many advantages such as no indoor air pollution, it is becoming widely used as heating equipment for general households and villas. The schematic structure of the conventional floor heating is as shown in FIG. FIG. 17A is a method of laying the hot water pipe 10 for floor heating using the space between the joists 1.
(B) is a method of laying a hot water pipe 10 for floor heating on the joist 1.

In FIG. 17 (a), in order to lay a hot water pipe 10, an elongated panel 2 of a heat insulating material, which is molded to fit the space between the joists 1, is used. This panel 2 includes a heat insulating layer 3 formed in advance in a slender shape, and a metal plate 4 having good heat transfer such as a zinc iron plate or aluminum laid on the heat insulating layer 3.
The heat insulating layer 3 and the metal plate 4 are formed on the upper surface of the panel 10 to form a recess 5 through which the hot water pipe 20 passes. After the control panel 2 is attached to the bottom of the joist 1 as a throwing tension, this panel 10 is set between the joists 1. After laying the hot water pipe 20 in the recess 5 of the panel 10, a floor finishing material 6 such as a flooring is attached. When hot water is flowed into the hot water pipe 20, heat is transmitted through the metal plate 4 and the finishing material 6
Is supplied to the bed and the temperature of the bed rises.

The space between the joists as described above can effectively use the space between the joists 1 and thus saves space. But,
In order to connect the hot water pipes 20, it is necessary to cut a part of the joists, and it is necessary to prepare a panel having different dimensions each time the joist spacing varies depending on the floor structure. Furthermore, since the floor above the joists remains cold, there is a temperature difference at each joist interval. Further, as shown in FIG. 18A, the finishing material 6 can be nailed only on the joist 1. Further, the portion corresponding to the panel 10 is the heat insulating layer 3
Since it is only supported by, the finishing material 6 may be deformed when it is soft and sinks, or when heavy furniture is placed.

In FIG. 17 (b), a control panel 2 is placed on the joist 1.
Is installed as a throwing slab, and a dedicated panel 11 is laid on one side thereof, and then a hot water pipe 20 is laid. This panel 11 is also structurally substantially the same as the panel 10, and is formed and adhered according to the shape of the heat insulating layer 3 in which a plurality of recesses 5 are formed at predetermined intervals and the shape of the upper surface of the heat insulating layer 3. It is composed of a metal plate 4 and a metal plate 4. If the hot water pipe 20 can be treated in the space of the joist 1 in this way, it is not necessary to penetrate the joist in order to continuously install the hot water pipe. In this construction method, a panel having a curved locus dent is also formed by using a heat insulating material, and these panels are combined to obtain a joist 1
Hot water pipes are laid on the top. Further, since the heat insulating material 9 can be laid between the joists 1, the panel 11 of this system can be relatively thin. Therefore, the floor finishing material 6 to be mounted on the panel 11 can be supported relatively firmly from the control panel 2.

In this construction method, as shown in FIG. 18B, the nail 8 for fixing the finishing material 6 is the heat insulating layer 3 of the panel 11.
Need to hit through. Therefore, it is necessary to use long nails, and instead, the floor cannot be firmly fixed. Further, since the heat insulating layer 3 expands and contracts due to the load applied to the floor, there is a concern that the nail will loosen. Furthermore, when fixing the panel 11 to the joist 1 or the control panel 2, it is necessary to hit the nail head so that the nail head does not protrude from the panel 11 so that the finishing material 6 does not flap. To do that, panel 1
It is necessary to nail the metal plate 4 provided on the upper surface of 1 until the plate is recessed.

Floor heating using hot water is becoming widespread in ordinary households, but at present, hot water pipes are laid using the above-described custom-made panel, and , Professional skills and experience are required to install these panels. Therefore, at a construction company or the like that undertakes the construction of a general house, the floor heating installation is ordered from a specialist, and it is difficult to reduce the floor heating cost. In addition, it is necessary to adjust the construction period because a specialist contractor will enter during the construction of the floor. Furthermore, the floor tends to be thicker because a space for installing a dedicated panel is required.

[0008] Therefore, an object of the present invention is to provide a structure capable of realizing floor heating for a general contractor without using a panel which requires special skill and experience. Another object of the present invention is to provide a structure capable of easily installing a heating device using warm water not only on the floor but also on a roof and the like, and a base panel suitable for the structure.

In particular, when it is used for floor heating, it has the advantages that a wooden flooring can be securely and easily attached, and that the floor can be constructed first, and it can be constructed at a low cost in a short period of time. It is also an object to provide a floor structure for floor heating and a base panel suitable for the floor structure. In addition, by freely setting the route and density of the hot water pipes, it is also an object to provide a base panel and a floor heating floor that can properly maintain heating in each room or place and realize comfortable floor heating. .

[0010]

[Means for Solving the Problems] The work of a general builder is mainly processing and assembling wood-based members, and the skills and experience related to these techniques are abundant. Therefore, if a floor panel for floor heating can be constructed by using a woody panel without using a special panel such as a molded heat insulating material, it is possible to quickly construct a building within the range that can be handled by a general contractor. Therefore, in the present invention, a wood-based flat plate-like base panel having a plurality of grooves formed in parallel on at least one of the front and back sides thereof is prepared, and the base panel is used as a support member such as a floor. The heating device can be configured by installing the hot water pipe in the groove formed in the base panel.

The base panel of the present invention may be constructed by engraving a plurality of grooves on the surface of a thick plate, or by attaching a band-shaped plate material on either the front or back surface of the substrate with a certain gap. May be. The so-called 3 ×, which is currently diversified in architecture
When adopting a size called 6 plates (910 mm x 1820 mm), when 170 mm wide plate materials are repeatedly pasted with a gap of 12 mm, a groove with a 12 mm square cross section becomes 1
It can be formed at intervals of 70 mm. Alternatively, of course, the interval may be half, that is, about 79 mm. Also,
If the edge of the base panel is processed in a step shape with a width half that of the groove formed in the panel, the grooves can be easily formed over a wide area at equal pitches by repeatedly installing the base panel.

Further, if a groove is provided on one surface of the base panel and a heat insulating material such as a styrofoam plate is pasted on the other surface, a base for heating can be completed simply by placing it on a supporting member such as joists. Further, since the heat insulating material such as the styrofoam plate has a good compatibility with concrete, it is possible to easily form the floor heating floor on the concrete soil.

The base panel according to the present invention can be handled almost the same as wood, which is widely used in building construction. Therefore, the area where the hot water pipe is laid can be easily constructed by carpentry work. In particular, since the base panel according to the present invention can be used as it is as a base panel for a normal floor or the like, it is not limited whether or not hot water pipes are installed, and for example, the base panel of the entire building can be formed by the base panel of the present invention. You can Furthermore, it is possible to easily construct a groove that connects the grooves prepared on the base panel with a router etc. on site. Therefore, a worker of a general construction shop such as a carpenter can freely set the laying route of the hot water pipes according to the arrangement of the room and the floor plan in the room. In addition, the hot water pipes may be densely laid at locations where the heating load is large, such as windows, and the hot water pipes may be laid at locations where the heating load is low by skipping grooves.

The base panel according to the present invention has these advantages, and further, a panel for forming a heat insulating material into a special shape or a specially processed panel such as digging a groove is not required, so that it is applied to a floor for floor heating. The cost can be reduced significantly. As hot water pipes, pipes made of cross-linked polyethylene or the like that are easy to lay and have high reliability are commercially available. Therefore, the work of laying the pipes is also easy.

Since the base panel of the present invention is entirely made of wood, it also has a function as a throwing support for attaching and supporting a floor finishing material. Therefore, since members under the floor such as abandoned tension, which are used in the conventional construction method, can be omitted, the floor thickness can be reduced and the construction cost can be reduced. Further, the base panel and the plate material can be easily fixed to the floor supporting member such as joists with nails. The top surface of the nail is wood, not metal, so the nail head is easy to handle. Also,
Since this base panel and plate are entirely made of wood, flooring materials such as flooring can be nailed anywhere on them by avoiding hot water piping.

It is also effective to install a metal plate having excellent thermal conductivity in order to uniformly heat the floor. The metal plate can be provided between the floor finishing material and the above-mentioned plate material so as to cover the hot water pipes laid in a plurality of gaps. It is also good to lay it on the board and the board. You may process a metal plate into a shape according to a groove. Furthermore, since the metal plate can be fixed by being sandwiched between the floor finishing plate and the plate material, it is not necessary to nail the metal plate itself. If the floor finishing material is nailed, the metal plate can also be fixed, so that the treatment of the nail head is easy.

Further, in the floor heating having such a structure, the metal plate is in contact with the upper portion of the pipe where the temperature easily rises due to the hot water flowing through the hot water pipe, so that the floor warms quickly. Furthermore, in this method, if a flat metal plate is laid on the hot water pipe, this metal plate is placed on the bent area of the hot water pipe or on the connection pipe laid between the boiler and the boiler. By also extending, it is possible to efficiently heat a wider floor surface on average.

The base panel of the present invention may of course be produced on site, but it is desirable to prefab it beforehand.
It can be constructed at a low cost in a short construction period by eliminating the work such as mounting the plate material with matching dimensions on site. Further, since the width of the gap and the precision of the gap can be increased by the factory prefab, the efficiency of floor heating can be improved and the floor temperature can be made uniform.

Since the prefabricated base panel can be easily cut and assembled by a jig used in carpentry work,
It can be used not only when forming a floor heating area where floor heating is actively performed, but also when laying a pipe for supplying water to the boiler. It is also possible to configure a device for heating snow such as eaves to melt snow by using the base panel of the present invention for the base of the roof. Further, the base panel may be mounted on the support member with the grooved surface facing down. This creates a region that can be nailed anywhere, at the same height as the floor heating location. By constructing such a structure near the wall of the floor, it is convenient for fixing the floor finishing material and constructing the skirting board.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a developed schematic structure of a floor for floor heating according to an embodiment of the present invention. Further, FIG. 2 shows a cross section of the assembled floor for floor heating of this example.

In the floor heating floor of this embodiment, a base panel 30 installed on the joist 1, a hot water pipe 20 laid in a plurality of grooves 35 provided in the base panel 30, and a base panel 30. Thin metal plate 25 laid on top of the metal plate 25
And a floor finishing material 6 laid on the floor. A heat insulating material 9 is laid between the joists 1.

As shown in FIG. 3, the base panel 30 of this example.
Is composed of a woody flat plate 31 such as a veneer plate called a control panel, and a plurality of woody strip-shaped plate members 32 attached on the flat plate 31. It is used as a base panel for floors. The flat plate 31 may be a veneer plate having a thickness that is normally installed under the floor as a throwing up, and has a thickness of, for example, about 12 mm. Further, the plate member 32 may be a plate member having substantially the same thickness as the outer diameter of the hot water pipe 35 to be constructed, for example, a plate member of about 9 mm.
A plurality of such plate members 32 are attached to one surface 33 of the flat plate 31.
In addition, they are regularly attached with a fixing device such as an adhesive or nail at regular intervals. Then, the plate member 32 is provided on the surface 33 of the flat plate 31 with a gap 35 having a width of about 9 mm to be about 30 mm.
It is formed with a pitch of 0 mm. Of course, various dimensions such as the thickness of the base panel, the width of the gap 35, and the pitch are not limited to the above, and can be set according to the load condition of the floor, the diameter of the hot water pipe, the amount of heat generation, and the like.

Further, the floor heating floor shown in FIGS. 1 and 2 can be constructed without using the prefabricated base panel 30. However, the construction using the prefabricated base panel 30 in the factory has many advantages in terms of construction period and pipe laying accuracy. Further, the base panel 30 of this example is a combination of members that are commonly used at a building construction site. Therefore, there is no need to form the heat insulating material in a special shape or to dig a groove of a special shape in the plate, and the panel can be easily manufactured at a factory and can be provided at low cost. Further, if desired, such a base panel can be manufactured at a construction site. When the floor area for floor heating is large, a plurality of base panels 30 may be combined, and when the floor area is small, the base panel 30 may be cut according to the floor. It is easy to cut or combine the base panel of this example on the spot according to the shape of the floor with a jig that has been used conventionally, and it is possible to carry out construction utilizing the experience and skill of carpentry work. Therefore, even a floor having a complicated shape can be easily constructed.

As shown in FIG. 4, when constructing the floor heating floor of this embodiment, first, the base panel 30 is mounted on the joist 1 which is a floor support member. Since the base panel 30 of this example is all made of wood and functions as a throwing up when a floor finishing material is applied, if the base panel 30 of the present example is put on the joist 1, it will be used as a throwing up. You can omit the control panel. Further, since the base panel 30 of the present example is a combination of wood-based members, it can be firmly attached to nails and can be firmly fixed. Even after nailing to the joist 1, there is no expansion or contraction unlike the heat insulating material, so the installation will not loosen. Further, since the head of the nail 8 is easily set inside the base panel 30, it is easy to finish the upper surface of the base panel 30 flat.

Next, the groove 3 prepared in the base panel 30.
The hot water pipe 20 is laid in the position 5. As hot water pipes for floor heating, pipes suitable for hot water pipes such as crosslinked polyethylene pipes and seamless pipes have been commercially available in recent years. These pipes are lightweight, flexible, and have excellent durability and scale resistance, so floor heating can be performed without fear of water leakage. In addition, jigs for connecting these pipes are commercially available, and the construction of hot water pipes is a work that even a general contractor will not burden.

After laying the hot water pipe 20, the hot water pipe 20
A flat metal plate 25 is placed so as to cover the base panel 30. As the metal plate 25, a zinc iron plate, an aluminum plate, or the like, which has good heat transfer and excellent durability, can be used. The plate thickness may be 0.35 mm, 0.6 mm, etc., and may be determined in consideration of the material and strength. In the floor for floor heating of this example, a flat metal plate 25 that is generally commercially available is used as a heat transfer member. Therefore, there is no need for a metal plate that has been specially processed according to the conventional pipe,
In this respect, the floor construction cost can be reduced. Moreover, since a flat metal plate is sufficient, it is easy to process on site. For this reason, the metal plates can be cut according to the shape of the floor, or the metal plates can be combined and laid on the floor, and every corner of the floor can be heated.

On the metal plate 25, the floor finishing material 6 is applied. Wood flooring is often used as a floor finishing material.
Fixed at 0. In the floor heating floor of this example, since the base panel 30 located below the finishing material 6 is entirely made of wood, the nail 8 that fixes the finishing material 6 penetrates the metal plate 25 and reaches the panel 30. That's fine. In addition, since the woody panel 30 is located immediately below the metal plate 25, the nails are well sharpened and the finishing material 6 can be firmly fixed. Further, compared to the conventional case where the heat insulating layer is below the finishing material, the strength of the floor is high, and there are few problems such as denting of the finishing material due to heavy objects.

Further, in the floor heating floor of this example, the metal plate 25 is sandwiched and fixed between the finishing material 6 and the base panel 30. That is, the metal plate 25 is fixed with nails struck from above the finishing material 6. Therefore, it is possible to save the trouble of nailing the metal plate 25, and it is possible to prevent the trouble that the head of the nail projects from the metal plate 25 and the finishing material 6 flaps.

When fixing the finishing material 6, it is important not to damage the hot water pipe. When the construction is performed using the base panel 30 in which the pitch of the gaps 35 is set with high accuracy as in this example, the position of the hot water pipe is clear and the pipe is not damaged. Further, by performing the work while sandwiching the metal plate with the finishing material 6, it is possible to perform the work while confirming the position of the pipe. Further, a metal plate with holes such as punching metal may be used, or the construction may be performed while confirming the position of the pipe.

As described above, the floor heating floor of this example can be easily constructed in a short period of time by using the wooden base panel 30. Moreover, the performance as a floor heating can be fully exhibited. In this example, a pipe having an outer diameter of approximately 9 mm is used as the hot water pipe 20. Therefore, the hot water pipe 20 is accommodated in the groove 35 prepared in the base panel 30, and the upper region of the hot water pipe 20 where the temperature is high contacts the metal plate 25 for heat transfer. Further, as shown in FIG. 5A, since the pipe made of plastic such as cross-linked polyethylene expands due to the temperature rise, a sufficient contact area with the metal plate 25 can be secured. Therefore, the width of the groove 35 may be slightly wider than the outer diameter of the hot water pipe in order to make a construction error and to facilitate the construction of the hot water pipe. This is because even if the groove 35 is somewhat wide, sufficient contact with the metal plate 25 arranged above can be secured if the pipe expands. Of course, after laying the hot water pipe 20 in the groove 35, the groove 35 may be filled with a heat transfer material such as heat conductive cement.

In order to increase the contact area with the metal plate 25, one end of the metal plate 26 that is bent or pressed into a U shape as shown in FIG. 5B may be inserted into the groove. Alternatively, a metal plate having a plurality of grooves formed according to the intervals and widths of the grooves 35 of the base panel is used as the groove 35 and the base panel 35.
It may be installed on top of. Even if the hot water pipe 20 is laid in the groove of the metal plate, the contact area between the metal plate and the hot water pipe can be increased, and efficient floor heating can be provided. Also,
As shown in FIG. 5C, an elastic band 27 such as packing may be attached to the bottom of the groove 35. It goes without saying that the floor heating capacity can be adjusted by changing the pitch of the grooves 35 and the diameter of the hot water pipe 20.

6 and 7, the base panel 30 of this example is shown.
An example in which a floor for heating is configured by combining the above is shown.
FIG. 6 shows an outline of a floor structure using a cross section. Further, FIG. 7 shows a schematic plan configuration of the floor excluding the floor finishing plate and the metal plate.

In the heating area for actively heating the central portion of the floor, the base panel 30 is combined so that the surfaces on which the grooves 35 are formed face upward and the grooves 35 are arranged in parallel.

Then, hot water pipes 20 are laid in these grooves 35. On both sides of the heating area corresponding to the left and right of FIGS. 6 and 7, without using the base panel 30, one more control panel 39 is attached on the joist 1. A vent portion 21 for laying a pipe over a plurality of grooves 35 is installed in an open space above the control panel 39.

The joist 1 is supported by a large pull 41 at the wall 40 on the left side of FIGS. 6 and 7. The base panel 30 is attached to the joist 1 with the groove 35 facing downward, outside the space where the vent portion 21 of the hot water pipe 20 is installed and at a position substantially above the large draw 41. Since the base panels 30 on both sides of the space in which the vent portion 21 of the hot water pipe 20 is installed are only attached to the joist 1 upside down, the heights of both sides of the vent portion 21 are the same. Therefore, if the metal plate 25 and the floor finishing material 6 are attached to the base panels 30 on both sides of the vent portion 21, a flat floor surface can be easily constructed. Although there is no base panel in the space of the vent portion 21, since the width of this space may be narrow, the metal plate 25 and the floor finishing material 6
Can secure sufficient floor strength. Of course, the space of the vent portion 21 may be filled with a heat insulating material or a heat conductive cement. Further, by covering the vent portion 21 also with the metal plate 25, the heat generated in the vent portion 21 can be used to substantially evenly heat the floor surface outside the heating area.

In the case of the wall 40, the base panel 30 can be mounted with the groove 35 facing downward to form a wood-based base having no irregularities. Therefore, it is convenient when nailing the end portion of the floor finishing material, and when setting the skirting board 42, it is not necessary to select the location where the nail is nailed.

At the wall on the right side of FIGS. 6 and 7, the base panel 30 is cut into a width that allows two grooves 35 to be prepared, and is attached on the joist 1 so that these grooves are orthogonal to the heating area. . That is, on the wall, the base panel 30 is attached so that the groove 35 runs parallel to the wall. A pipe 22 for supplying or discharging hot water from the boiler to the heating area is laid in the groove 35 near the wall. As described above, since the base panel 30 of this example can be freely cut or combined, the hot water pipe can be easily arranged within the scope of carpentry work. Further, the pipe 22 running along the wall can be covered with the metal plate 25, so that the pipe 22 can also be used as a heat source for floor heating, and the floor can be heated substantially evenly. As described above, in the floor heating floor of this example, it is possible to easily warm every corner of the floor by using the flat metal plate.

(Embodiment 2) A different embodiment of the present invention will be described below. In the following, the above-mentioned embodiment and 37
The parts to be denoted by the same reference numerals are omitted. FIG. 8 and FIG. 9 show how the base panel 30 according to this embodiment is installed on a systemized joist 50 to form a floor. As shown in FIG. 10, the base panel 30 of this example is configured by sticking a plurality of woody strip-shaped plate members 32 on a woody flat plate 31 such as a plywood plate, and the thickness of each is, for example, about It is 12 mm. The flat plate 31 has a width W of 910 mm and a length L of 1820 mm, which is a so-called 3 × 6 plate that is often used in building construction and the like, and five plate materials 32 having a width b of 170 mm are attached to this surface. It is attached. The plate members 32 are attached in parallel with each other with an interval a of about 12 mm. The plate members 32 form four grooves 35 having a 12 mm square cross section on the flat plate 31 substantially in parallel. Further, the plate member 32 is the flat plate 3
It is affixed to the edge of the flat plate 31 at a position that is inwardly about 6 mm from the edge of the flat plate 31.
A stepped portion 37 having a width c which is a half of the above is formed.
On the back surface of the flat plate 31, that is, on the side opposite to the surface on which the plate member 32 is attached, a styrofoam plate 60 is attached on the entire surface. The styrofoam plate 60 functions as a heat insulating material, and also has the effect of increasing the adhesion to the concrete soil. It goes without saying that the above-mentioned dimensions are merely examples of the base panel according to the present invention. For example, if the width b is about 79 mm, it is 9
The groove 35 of the book can be formed, and the interval a may be set to about 9 mm according to the thin hot water pipe. The thickness of the flat plate or the plate material is not limited to the above, and a plate of about 9 mm may be used, for example.

Returning to FIG. 8, systematized joists 50
Is constructed so that it can be installed on waste concrete or foundation concrete to support the floor,
For example, a substantially square support portion 51 that supports a floor material, a rod 52 that adjusts the height of the support portion 51, and a support portion 5
Base 5 for supporting 1 against the concrete surface 59 as the base
And 3. By arranging such systemized joists 50 at an appropriate density according to the weight of the floor, it is possible to easily construct the floor without constructing a beam such as a large pull that supports the floor with wood or steel frame unlike the conventional method. Can be configured. When constructing a floor using the base panel 30 and the systemized joist 50 of this example, the edge 37 of the base panel 30 is arranged in accordance with the arrangement of the systemized joist 50. Then, when the foundation panel 30 is placed on the joists 50, the foundation of the floor is immediately formed.

Since a plurality of grooves 35 run in parallel on the upper surface of the base panel 30, floor heating can be easily performed by laying the hot water pipes 20 in the grooves 35.

More specifically, as shown in FIG. 9, since the Styrofoam 60 is attached to the lower surface of the base panel 30 of this example as a heat insulating material, it can be placed on the joist 50 as it is. The insulation work is completed. Of course, it is possible to add more insulation under the floor later. Further, a plurality of grooves 35 are formed in parallel on the upper surface of the base panel 30 in advance, and further, since a step 37 is prepared at the edge of the base panel 30, when the base panels are put together, they are aligned with each other. The groove 35 having substantially the same width is also formed in the portion 38. Therefore, when the base panel 30 of the present example is laid, a constant interval, 170 mm in the present example.
A floor base is completed in which the grooves 35 having a width of 12 mm are formed substantially in parallel at intervals of. Then, a hot water pipe 20 is laid by obtaining an appropriate groove among these grooves 35, and the floor finishing material 6 is nailed thereto to complete the floor heating floor.
In this example, the width of the groove is determined so that a hot water pipe having a diameter of 11 mm is laid, but the width of the groove can be determined according to the diameter of the hot water pipe laid as in the first embodiment. Of course, a hot water pipe having a diameter of 9 mm may be laid in the groove having a width of 12 mm in this example.

The base panel according to the present invention is very suitable for a floor construction method using such a systemized joist. First, two plates, that is, the flat plate 31 and the strip-shaped plate material 3
Since it is composed of two layers, No. 2 and No. 2, it is thick and has high strength. Therefore, the strength required for the floor can be secured simply by placing it on the joist 50. Further, since both the flat plate 31 and the plate member 32 are made of wood, a sufficient thickness for fixing the floor finishing material 6 with the nail 8 can be obtained. That is, as described in the first embodiment, in order to fix the floor finishing material 6 using the nails 8, a woody portion having a thickness that does not penetrate the nails is required. Therefore, by installing the base panel of the present example, the nail 8 can be struck at any place except the groove 35, so that the floor finishing material can be securely fixed without trouble. Further, as described above, the heat insulation work can be performed only by placing the base panel of this example. Therefore, the base panel of this example is excellent not only for floor heating using a hot water pipe, but also as a base panel constituting a floor.

Further, as shown in FIG. 11, the base panel 30 of this example is also useful in a construction method in which the ground panel 59 is directly placed on a soil floor 59 to construct a floor. Even if a wood panel is laid between concrete soils, the concrete and the panel are not so well-adapted to each other, and thus peeling or distortion may occur. However, in the base panel 30 of this example, the styrofoam plate 60 is attached to the back surface in advance. The thermal insulation material such as Styrofoam and the concrete have a good familiarity, and since the thermal insulation material and the woody part have been firmly adhered to each other in advance, problems such as peeling of the base panel from the concrete surface and distortion may occur. Can be prevented. further,
Since there is a heat insulating material between the concrete floor 59 and the floor, the amount of heat that escapes to the floor is reduced when floor heating is performed.
You can speed up the rise of the floor temperature. Further, as described with reference to FIG. 9, since the base panel of this example has a secured thickness of the wooden portion, it is suitable for nailing the floor finishing material. Of course, it can also be applied to floors that are not nailed, such as cushion floors.

Further, if the base panel 30 of this example is used, floor heating using the hot water pipe 20 can be easily installed. The floor heating floor using the base panel 30 of this example is a groove 35.
Since the route of the hot water pipe 20 can be freely set by using, the laying density of the hot water pipe can be changed according to the heating load. That is, in a room or place where the heating load is low, one or more grooves 35 can be skipped to lay a hot water pipe. On the other hand, in a room or place with a high heating load such as a window, a hot water pipe can be laid in the entire groove 35 to enhance the heating effect. Further, it is possible to enjoy sufficiently comfortable floor heating without laying a metal plate between the base panel 30 and the floor finishing material 6. A base panel in which the distance between the grooves is set to about 79 mm or less may be laid, which further expands the range in which the laying density of the hot water pipes can be adjusted.

A process of performing a floor-first construction using the base panel 30 of this example will be described with reference to FIGS. First, as shown in FIG. 12, a plurality of base panels 30 are laid between the conventional joists as described above, systemized joists, or concrete soil. Outer wall 71
These floor panels 30 between the floor floors 7 of the building.
0 is completed, and the grooves 35 run in parallel on the upper surface of the floor base with a substantially constant interval. Since these base panels 30 can be spread in the building regardless of the position of the partition wall or the like, the floor base 70 can be completed very quickly.

Next, as shown in FIG. 13, a partition wall 72
To form. Around this, the groove 3 by a router etc.
A U-shaped groove 65 for connecting 5 is formed on the base panel 30. Since the base panel 30 of this example is made of wood, the U-shaped groove 65 can be easily formed by a router or a chisel. The location of forming the U-shaped groove 65 may be any location as long as it is on the base panel. That is, the grooves 35 are preliminarily formed in the base panel 30 of this example at substantially equal intervals, and further, the grooves 37 are formed at the same pitch at the joints between the base panels. Therefore, the U-shaped groove 65 can be easily formed at the edge of the base panel, in the center thereof, or at a position extending over a plurality of base panels. Also, U
The V-shaped groove 65 is not limited to the one that connects the adjacent grooves 35, but it is also possible to form the groove 65 that extends so as to skip one or more grooves. U-shaped groove 65
Need only be formed with a radius that allows the hot water pipe to be laid comfortably, and the position of the groove 65 can be freely adjusted on site based on the structure of the building, the layout of the room, the layout of furniture in the room, and the like. For example, since the heating load is likely to be high in the portion close to the outer wall 71, the adjacent grooves 35 are formed into U-shaped grooves 65.
It is possible to increase the density of hot water pipes by connecting with.
On the other hand, since the heating load may be low in the center of the room, one groove can be opened and connected to reduce the density of the hot water pipes. Further, the arrangement of the hot water pipes can be adjusted so that the supply side and the discharge side of the hot water pipes are gathered in the same direction of the room by the U-shaped groove.

A hot water pipe 20 is laid as shown by a solid line in FIG. 14 on a route 67 constituted by the U-shaped groove 65 and the straight groove 35. The floor for heating is completed. Of course, the floor finishing material 6 may be attached without installing the hot water pipe, and a cushion floor or the like can be used. As described above, by using the base panel 30 of this example, it is possible to finish a floor capable of floor heating in a short period of time by the floor preceding method. Further, by using the base panel 30 of the present example, the route, density, etc. of the hot water pipe can be freely set, and further, if the construction of the wood-based material is done on site, the worker of the work shop can adjust it. Therefore, not only can floor heating be constructed at low cost in a short period of time, but it is also possible to provide very comfortable floor heating that takes into consideration the user's intention, the layout of the building, and the layout of furniture. In addition, as described above, the base panel of the present example can surely perform the finishing work and has a high heat insulating effect.

The heating device using the base panel 30 of this example is not limited to floor heating. For example, as shown in FIG.
The base panel 30 is laid on the roof eaves 80, and the groove 35
You may lay hot water piping in. As a result, the snow accumulated on the eaves 80 can be melted, and troubles caused by falling snow or icicles can be prevented. An example of installing the base panel 30 on the eaves tip 80 of the roof is shown in FIG. A part of the eaves end of the joist 81 supporting the roof is cut down by one step, for example, about 12 mm in accordance with the base panel of this example, and the base panel 30 of this example is attached so that the groove is parallel to the eaves. Then, a 12 mm roof underlay 82 is provided on the portion without the base panel 30 to make the height uniform, and then a steel plate 83 or the like is stretched to complete the roof. A hot water pipe is laid in the groove 35 of the base panel 30 as in the case of floor heating, and hot water is caused to flow in the winter to melt snow. As described above, by using the base panel of this example, it is possible to set the heating area not only on the floor but also on the roof, the wall, or the like at a low cost and very easily. You can form a comfortable home.

In the above example, the explanation is mainly based on the wooden building, but the base panel according to the present invention can be used even for a concrete or brick building. Further, the base panel according to the present invention may be of a plywood type in which flat plates and plate materials are bonded together,
A groove may be machined on a flat plate. Further, when the plate materials are bonded together, the number of flat plates or plate materials is not limited to one layer, and it is of course possible to stack a plurality of plates.
Further, the above-described dimensions such as the intervals, the grooves, and the plate thickness are examples of the base panel of the present invention, and are not limited to these dimensions.
