2. Description of the Related Art Conventionally, a floor heating device arranged under a floor of a house or the like has been known. This floor heating device, for example,
It has a layer structure as shown in FIG. That is,
The floor heating device 50 includes a lower plate 54 placed on an upper surface of a plurality of joists 52 arranged on a large pulling 51, a small joist 55 arranged on the upper surface of the lower plate 54, and a foam insulating material. The floor heating panel 56, these small joists 55 and the floor heating panel 56
And a floor plate 57 placed on the upper surface of the main body. Here, a routing groove 60 for the hot water pipe 59 is formed on the upper surface side of the floor heating panel 56. The lower plate 54, the floor heating panel 56, and the floor plate 57 each have a thickness of about 12 mm.
Generally, when the floor heating device 50 is installed, the lower plate 54, the floor heating panel 56, and the floor plate 5
The total thickness of 7 is about 36 mm.

[0003]

However, in such a floor heating device, since the floor heating panel 56 is formed of a foamed heat insulating material, the lower plate 54 is laid on the upper surface of the joist 52 in terms of strength. When the floor heating device 50 is installed in a house having a limited underfloor space due to reform or the like, the following inconvenience is caused. In other words, before the floor heating device 50 is constructed, the lower plate 54 and the floor plate 57 each having a standardized thickness of 12 mm are laminated on the upper surface of the joist 52, The height up to the upper surface of 57 is about 24 mm including the lower plate 54 and the floor plate 57. From this state, if the floor heating panel 56 is installed as it is between the lower plate 54 and the floor plate 57, its thickness is about 12 mm.
For this reason, there is a step where the floor is higher than the lower edge of the window frame, the door frame, or the like. Therefore, the floor heating panel 56 cannot be installed in this type of house. In this case, if the above-described lower plate 54 is excluded, it is theoretically possible to form a book shape and prevent a step from being generated. Cause inconvenience.

SUMMARY OF THE INVENTION The main object of the present invention has been devised in view of such inconvenience. The object of the present invention is to provide a floor heating panel without adjusting a step on a floor surface. An object of the present invention is to provide a floor heating device that can be easily constructed.

Another object of the present invention is to provide a floor heating apparatus which can prevent inadvertent jumping out of a hot water pipe incorporated in a floor heating panel when running the hot water pipe by a simple means. It is in.

[0006]

In order to achieve the above-mentioned main object, the present invention provides a floor heating panel which forms a hot water pipe running groove on an upper surface side of a plurality of joists arranged at predetermined intervals. In the floor heating device in which a floor plate is arranged on the upper surface of the floor heating panel, the floor heating panel is configured to include a plate material and is provided so as to be directly mountable on the upper surface of the joist. I do. According to such a configuration, since the floor heating panel can be directly mounted on the upper surface of the joist, there is no need to lay a lower plate or the like when installing the floor heating panel from the strength aspect, and after the floor heating panel is installed. A step corresponding to the thickness does not occur on the floor surface. Therefore, when the floor heating panel is installed, the step of adjusting the floor surface is not required, and the floor heating device can be easily installed.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, it is preferable to adopt a structure in which a reinforcing plate which does not interfere with the upper surface of the joist is provided on the lower surface side of the floor heating panel. Thereby, the strength against the load from above the floor heating panel can be further increased.

The floor heating panel is formed by spanning a heat transfer plate between a plurality of panel forming members.
It is preferable to adopt a configuration in which a routing groove for a hot water pipe is formed in the heat transfer plate. According to such a configuration, since the routing groove is formed by combining a plurality of panel forming members and bridging the heat transfer plate therebetween, a concave groove is formed on the upper surface side of the floor heating panel by cutting or the like. Therefore, the floor heating panel can be more easily processed. Here, it is preferable that a groove width of the routing groove is provided to be slightly narrower than an outer diameter of the hot water pipe, and a slit hole is formed in a side wall portion where the routing groove is formed. By doing so, when the hot water pipe is forcibly housed in the routing groove,
The area near the slit hole in the side wall is deformed so as to follow the outer shape of the hot water pipe and spread outward, and the hot water pipe fits in the routing groove. For this reason, the hot water pipe can be firmly held in the routing groove without employing a means such as attaching a soaking tape between the hot water pipe and the floor heating panel, thereby further improving the efficiency of the construction work. Can be achieved.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a floor area to which the floor heating device of the present invention is applied, and FIG.
An enlarged cross-sectional view taken along the line A is shown. In these figures, the floor heating device 10 includes a plurality of floor heating panels 13 placed on the upper surfaces of a plurality of joists 12 that are bridged at regular intervals on the upper surface of a plurality of pulleys 11, and these floor heating panels. 13 and heat insulating materials 16 and 17 disposed between the pulleys 11 and 11 and between the joists 12 and 12, respectively.
It is comprised including.

The floor heating panel 13 includes a straight panel 13.
A and a corner panel 13B. Here, the straight panel 13A includes a plurality of panel forming members 18 made of a plate material such as wood having a thickness of about 12 mm,
It comprises a reinforcing plate 19 fixed to the lower surfaces of these panel forming members 18, 18 and a heat transfer plate 20 intermittently bridged between the panel forming members 18, 18.

As shown in FIG. 3, the panel forming member 18 is disposed with a certain gap between the adjacent panel forming members 18 and 18, and the heat transfer plate 20 enters the gap. A routing groove 24 for the hot water pipe 23 (see FIG. 2) is formed. Here, the floor heating panel 13
In the region where the heat transfer plate 20 is not provided, the upper surface side is an adhesion region with the floor plate 14 and the lower surface side is a region where the joists 12 are laid. For this reason, as shown in FIG. 2, in a region where the heat transfer plate 20 is not provided, a nail, an adhesive, or the like is used.
The floor heating panel 13 can be fixed to the floor plate 14 and the joist 12.

A plurality of the reinforcing plates 19 are provided so as to be substantially orthogonal to the extending direction of the panel forming member 18. When the floor heating panel 13 is installed on the upper surface of the joist 12, the reinforcing plate 19 is provided on the upper surface of the joist 12. It does not interfere. That is, when the floor heating panel 13 is installed on the upper surface of the joist 12, the reinforcing plate 19 is located between the joists 12, 12, and the lower surface of the panel forming member 18 directly contacts the upper surface of the joist 12. .

The heat transfer plate 20 is provided in a shape as shown in FIG. 4 by bending a metal piece such as iron or aluminum. That is, the heat transfer plate 20
Are a pair of horizontal surfaces 26, 26 seated on the upper surface of the panel forming member 18, and a side wall 2 which is suspended from the inner edges of the horizontal surfaces 26, 26 and formed in a substantially U-shape in side view.
7, 27. Here, a plurality of slit holes 30 are formed in the side wall 27. FIG. 5 (A)
As shown in FIG. 2, the separation width between the horizontal surfaces 26, 26, that is, the groove width W1 of the routing groove 24 is equal to the outer diameter W2 of the hot water pipe 23.
It is slightly narrower than that. Therefore, the heat transfer plate 20
When the hot water pipe 23 is drawn from above and forcibly pushed into the groove 24, the hot water pipe 23 is housed in the drawing groove 24 by elastic deformation of the heat transfer plate 20. That is, FIG.
When the hot water pipe 23 enters the routing groove 24, the area near the slit hole 30 in the side wall 27 is deformed outward following the outer peripheral shape of the hot water pipe 23, and the hot water pipe 23 is fitted into the routing groove 24, as shown in FIG. It is supposed to. For this reason, after the hot water pipe 23 is accommodated in the routing groove 24, it becomes difficult for the hot water pipe 23 to accidentally jump out of the routing groove 24. The side wall 27 in the extending direction of the routing groove 24
In order to prevent the hot water pipe 23 from being damaged by the edge, as shown in FIG. 4, the end side is folded outward by about 180 degrees so as to have a two-piece thickness, but is not limited thereto. In other words, if the hot water pipe 23 can be prevented from being damaged, other modes such as bending the end of the side wall 27 to approximately 90 degrees and making the region a flange shape can be adopted.

The floor heating panel 13 can be cut along a region where the heat transfer plate 20 is not provided, and can be appropriately arranged according to the size of the installation site.

The floor plate 14 has a thickness of approximately 1 made of wood.
Although not shown here, a heat equalizing sheet capable of transferring heat from the hot water pipe 23 to the floor plate 14 is attached to the back surface thereof.

Next, a procedure for installing the floor heating device 10 according to the present embodiment will be described.

First, a heat insulating material 16 is laid between the pulleys 11, 11, a plurality of joists 12 are fixed on the upper surfaces of the pulley 11 and the heat insulating material 16, and a heat insulating material 17 is arranged between the joists 12, 12. I do. Next, the floor heating panel 13 is fixed on the upper surface of the joist 12, and the hot water pipe 23 is accommodated in the routing groove 24. Here, the hot water pipes 23 are arranged in a zigzag shape along a predetermined direction of the floor area, and both ends thereof are connected to a heater such as a boiler (not shown). Thereafter, the floor plate 14 is fixed to the upper surface of the floor heating panel 13. Here, floor heating panel 1
The total thickness of 3 and the floor plate 14 is approximately 24 mm, but an error of approximately ± 1 mm is acceptable.

Therefore, according to this embodiment, since the floor heating panel 13 having a thickness of 12 mm can be directly mounted on the upper surface of the joist 12, the lower plate having a thickness of 12 mm and When the floor heating device 10 is installed on a floor of an existing house having floor boards by renovation or the like, the floor heating panel 13 can be installed without using a lower board. When installing the floor heating device 10, the floor heating device 10 can be easily constructed without performing a step adjustment process on the floor surface.

Further, since the slit hole 30 is provided in the heat transfer plate 20, the hot water pipe 23 from the routing groove 24 can be easily processed.
Can be effectively prevented. That is, since the slit hole 30 can be formed by, for example, press working, it can be formed more easily than other means for preventing the hot water pipe from popping out, such as providing a protrusion on the side wall 27.

In the above embodiment, the thickness of the floor heating panel 13 and the floor plate 14 are both approximately 12 mm.
The present invention is not limited to this, and the height from the upper surface of the joist before the construction to the upper surface of the floor panel, the floor heating panel 13 and the floor panel 14
The thickness of the floor heating panel 13 and the floor plate 14 may be equal to the total thickness of the floor heating panel 13 and the floor panel 14. For example, when the height from the upper surface of the joist before the construction to the upper surface of the floorboard is 24 mm, for example, when the hot water pipe 23 having an outer diameter of 13 mm is used, the thickness of the floor heating panel 13 is set to 15 mm, and May be 9 mm thick.

Further, the panel forming member 18 is formed of a plate material such as wood, but may be formed of another plate material having a strength with which bending and breakage hardly occur even when directly mounted on the upper surface of the joist 12. It is possible.

Further, in the above embodiment, the case where the floor heating panel 13 is arranged so that the extending direction of the routing groove 24 is orthogonal to the extending direction of the joist 12 has been illustrated and described, but the present invention is not limited to this. Instead, it is also possible to arrange the floor heating panel 13 so that the extending direction of the routing groove 24 is along the extending direction of the joist 12.

Further, as the heat transfer plate 20, for example, as shown in FIGS. 6 and 7, a plurality of routing grooves 24 can be formed in one unit, such as a type in which two routing grooves 24 can be formed in one unit. It is also possible to adopt a type in which the groove 24 can be formed.

Further, when the heat equalizing sheet is not attached to the back surface of the floor plate 14, a heat transfer plate 35 may be attached to the upper surface of the floor heating panel 13 as shown in FIG.

[0026]

As described above, according to the present invention,
Since the floor heating panel is configured to include the plate material and is provided so that it can be placed directly on the upper surface of the joist, after installing the floor heating panel, on the floor surface,
Since a step corresponding to the thickness of the floor heating panel does not occur, the step for adjusting the step on the floor surface becomes unnecessary, and the floor heating device can be easily constructed.

Further, since the reinforcing plate which does not interfere with the upper surface of the joist is provided on the lower surface side of the floor heating panel, the strength against the load from above the floor heating panel can be further increased.

Further, the floor heating panel is formed by bridging a heat transfer plate between a plurality of panel forming members, and a routing groove for a hot water pipe is formed in the heat transfer plate. There is no need to form a concave groove on the upper surface side, and the floor heating panel can be processed more easily.

Furthermore, since the width of the routing groove is provided slightly narrower than the outer diameter of the hot water pipe, and a slit hole is formed in a side wall portion where the routing groove is formed, the heat equalizing tape is provided between the hot water pipe and the upper part. The hot water pipe can be firmly held in the routing groove without employing means for preventing the hot water pipe from jumping out, such as by sticking it to the upper surface of the floor heating panel, thereby further improving the efficiency of construction work. Can be.
