[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A panel body P of the embodiment shown in FIGS. 1 to 7 has four sides surrounded by rectangular frame members 9 to 12 and frame members 9 to 12 surrounding these four sides from above and below. Laying boards 13 and 14 are fixed so as to be sandwiched therebetween.

As described above, the frame members 9 and 10 located on the long sides of the frame members constituting the panel body P are formed with the step portions 9a and 10a including the horizontal portion and the vertical portion. The step portions 9a and 10a of the frame members 9 and 10 have their horizontal portions turned upside down. The reverse of the horizontal part
This is because, as shown in FIG. 1, the horizontal portions of the panel main body P that overlap each other overlap each other. If the horizontal portions overlap each other in this manner, a gap cannot be formed between adjacent panel bodies P.

Further, the panel body P is constituted by sandwiching the upper and lower sides of the frame members 9 to 12 with the laying plates 13 and 14, and the frame members 9 to 12 and the laying plates 13 and 14 are formed.
A space 15 is formed in a portion surrounded by. In this space 15, a pipe mat m is set. In FIG. 2, the panel body P is turned upside down so that the laying plate 13 located on the upper side is turned down, and the pipe mat m is laid on the laying plate 13; FIG. 3 is a view showing a state in which a laying plate 14 located on a lower side is peeled off.

The pipe mat m as described above is composed of a pair of a thick supply main pipe 16 and a return main pipe 1.
7, a number of thin heat radiation pipes 18 are connected.
Each of the pair of main pipes 16 and 17 is provided with connectors 19 and 20. The connectors 19 and 20 connect the main pipes 16 and 17 to each other as shown in FIG.
Are connected to the supply pipe 23 or the return pipe 24 shown in FIG. 1 through the hoses 21 and 22 shown in FIG.

The supply pipe 23 is connected to a supply source of a warm fluid (not shown) on the side of the main unit 3 as in the conventional case, and the return pipe 24 is connected to a reservoir (not shown). are doing.

Further, in this embodiment, as shown in FIG. 2, three unit mats m1, m2 and m3 are connected to form one pipe mat m. Specifically, the main pipes 16 and 17 are divided into three, and the divided supply main pipe 16 and return main pipe 17 are divided.
Are connected by a heat radiating pipe 18. FIG. 2 shows a pipe mat m in which the main pipes 16 and 17 thus divided are further connected. The reason why the three unit mats m1, m2, and m3 are connected in this way is to provide reinforcing members 25 and 26 as shown in FIG.

That is, since the interval pitch between the heat radiating pipes 18 is very small, the reinforcing members 25, 26 are provided between the narrow pitches.
There is no room to place. Therefore, pipe mat m
By dividing into unit mats and connecting them, the interval pitch of the heat radiating pipes between the unit mats is increased. Reinforcing members 25 and 26 are provided at the interval pitch portions of the enlarged heat radiation pipes.

As described above, three unit mats m
By dividing the unit mat into 1, m2, and m3, the pitch between the heat radiating pipes 18 in each unit mat can be made different. The merits of making the interval pitch of the heat radiating pipes 18 different are as follows. For example, in the entire pipe mat m, the pitch can be determined according to the application, such as reducing the pitch interval at a place where people gather most and increasing the pitch interval at a location where furniture and the like are spread. By doing so, it is possible to reduce the amount of heat at a location below the furniture and minimize the energy loss.

However, the pipe mats m may be formed integrally while maintaining the pitch of the heat radiating pipes 18 as described above. In other words, whether to divide into three unit mats or keep them is a matter of manufacture only. Therefore, the most efficient method for manufacturing may be selected. The reinforcing members 25, 26
Is for preventing the panel body P from bending.

In the pipe mat m as described above, the heat radiating pipe 18 is fitted into an alignment sheet 28 made of an aluminum plate as shown in FIGS.
The configuration of No. 8 is as follows. The alignment sheet 28,
The same number of alignment grooves 28a as the heat dissipating pipes 18 are formed, and flat portions 28b parallel to the alignment grooves 28a are formed on both sides of the alignment sheet 28, that is, on both side edges in a direction perpendicular to the alignment grooves.
Is formed.

Then, the individual alignment grooves 28a
Then, each of the heat radiating pipes 18 is fitted. Thus, the heat radiating pipes 18 of the pipe mat m are aligned with the alignment sheets 28.
After being inserted into the alignment grooves 28a, the flat portions 28b on both sides of the alignment sheet 28 are placed on the frame members 9 and 10, and the flat portions 28b are sandwiched between the frame members 9 and 10 and the laying plate 13. To do. Thus, the flat plate portion 28
b, the alignment sheet 28 and its alignment groove 2
The heat dissipating pipe 18 fitted in 8a comes into close contact with the spreading board 13.

However, since the weights of the heat radiating pipe 6 and the main pipes 16 and 17 act on both ends in the longitudinal direction of the alignment groove 28a, a gap is formed between the alignment sheet 28 and the laying plate 13. . In order to fill the gap, as shown in FIGS. 6 and 7, a sealing material 29 is used. By using the sealing material 29 in this manner, not only can the gap be filled, but also the alignment sheet 28 can be bonded to the laying board 13 by utilizing the adhesive force of the sealing material. Therefore, the flat plate portion 28b of the alignment sheet 28 is
The alignment sheet 28 is tightly fixed to the back surface of the laying plate 13 in combination with being sandwiched between the laying plate 13 and the laying plate 13.

When the pipe mat m is set together with the alignment sheet 28 on the side of the laying plate 13 of the panel body P as described above, the laying plate 14 on the opposite side is covered, and the space 15 is covered with a lid. It is fixed to the frame members 9 to 12. In this state, that is, as shown in FIG. 2, the heat insulating material 27 made of a foamable resin is filled in the panel main body P while the spread sheet 13 located on the upper side is kept on the lower side. By filling the heat insulating material 27 in this manner, the alignment sheet 2
8 is pressed by the heat insulating material 27 and makes stronger contact with the upper spreading plate 13.

At this time, the heat insulating material 27 does not enter between the laying plate 13 and the alignment sheet 28. This is because the side surfaces of the alignment sheet 28 are brought into close contact with the frame members 9 and 10 by the flat plate portion 28b, and both ends in the longitudinal direction of the alignment groove 28a are covered with the sealing material 29. If the heat insulating material 27 penetrates between the alignment sheet 28 and the laying plate 13, the heat of the radiating pipe 18 at that portion will not be transmitted to the laying plate 13. However, if there is no gap between the laying plate 13 and the alignment sheet 28 as in this embodiment, good thermal conductivity can be maintained at any location.

The space 15 is provided with reinforcing members 25, 26.
, The filling of the heat insulating material 27 is naturally performed three times for each of the divided areas. Further, as the heat insulating material 27, a liquid urethane foam, a polystyrene foam, or the like can be considered, but besides these, glass wool or the like can also be considered. In any case, in the present invention, the material of the heat insulating material does not particularly matter.

Further, in this embodiment, FIGS.
As shown in the figure, a heat conductive sheet 30 made of aluminum foil is laid on the alignment sheet 28. However, this heat conductive sheet 30 is not only on the alignment sheet 28 but also on the frame members 9 to
It extends so as to extend between the upper surface of the base 12 and the laying plate 13 fixed thereon. Thermal conductive sheet 3 as described above
The reason why 0 is extended to the upper surfaces of the frame members 9 to 12 is that heat is not easily transmitted to the frame members 9 to 12.

In particular, in the illustrated embodiment in which the panel body P is rectangular and the main pipe 5 is positioned on the short side, there is a problem that the frame members 11 and 12 on the short side are difficult to warm. This is because a considerable space is required between the main pipe 5 and the frame members 11 and 12 on the short side, so that the temperature of the main pipe 5 is hardly transmitted to the frame members 11 and 12. The reason for requiring a space between the main pipe 5 and the frame members 11 and 12 is that the main pipe 5 is considerably thicker than the heat radiating pipe 6 and that the main pipe 5 is provided with connectors 19 and 20 and the like. Must be due to.

However, since the thin radiating pipe can be brought as close as possible to the frame members 9 and 10 on the long side of the panel body P, the heat of the pipe mat m is transmitted to the frame members 9 and 10 to some extent. Will be. Therefore, in this embodiment, first, the frame members 11 and 12 on the short side are
It is necessary to extend the heat conductive sheet 30 to the side. However,
If possible, expanding the heat conductive sheet 30 to all the frame members 9 to 12 naturally increases the thermal efficiency.

The panel body P constructed as described above
Is surrounded by rectangular frame members 9 to 12 and furthermore, reinforcing materials 25 and 26 are arranged therein, so that the rigidity of the spreading plates 13 and 14 is combined with the flexural rigidity. It will be very expensive. Therefore, the conventional joist 4 is not required. In other words, sufficient strength can be maintained even if the panel main body P is directly stretched between the pulleys 3. As described above, since the panel main body P can be directly stretched between the large pulleys 3, if the panel main body P is manufactured in advance at a factory or the like, it is sufficient to spread the panel main body P between the large pulleys 3 at the site. For this reason, the workability at the site is extremely improved as compared with the related art.

The frame members 9 and 10 of the panel body P
In addition, since the step portions 9a and 10a are formed and their up and down directions are reversed, when the panel body P is laid on the large block 3, the horizontal portions of the adjacent step portions of the panel body P are overlapped. Can be. Since the horizontal portions can be overlapped in this way, there is no gap between adjacent panel bodies P. Therefore, the cool air below the edge does not blow up, and the heating efficiency is improved accordingly.

Further, since the reinforcing members 25 and 26 can be formed as so-called nailing portions, for example, when the flooring or the like is spread over the panel body P, the flooring can be firmly stopped. Also, it is possible to prevent a nail from being accidentally driven into the pipe mat m.

Furthermore, since the spacing sheet 28 is provided to keep the space between the heat radiating pipes 18 of the pipe mat m, the space between the heat radiating pipes 18 becomes uneven and the heat distribution on the laying plate 13 becomes unstable. It will not be. Moreover,
The periphery of the alignment sheet 28 is formed by a flat plate portion 28b and a sealing material 29 so that no gap is formed.
8 and the spreading plate 13 do not invade. Therefore, the thermal efficiency is good.

[0029]

According to the first aspect of the present invention, the panels can be laid directly on the groom without providing joists. In other words, since the number of construction steps on site can be extremely reduced, the workability can be significantly improved. Moreover, with the radiation pipe of the pipe mat fitted in the groove of the alignment sheet, between the upper surface of the frame member and the laying plate fixed on it
Since the flat portion of the alignment sheet is sandwiched and fixed, the heat insulating material can be filled with the pipe mat installed in the panel body. Therefore, when the panel body is filled with the heat insulating material, the position of the pipe mat is not shifted, or the intervals between the heat radiating pipes are not uniform, so that the uniformity of the heat distribution is not lost.

According to the second and third aspects of the present invention, heat is well transmitted to the frame member side, and the heat distribution on the laying board can be always kept constant. According to the fourth aspect, the heat insulating material does not enter between the alignment sheet and the laying plate. Since the heat insulating material does not enter between the alignment sheet and the laying plate, heat conduction in that portion can be efficiently maintained. According to the fifth aspect of the present invention, since the flexural rigidity of the panel is further increased, the panel does not bend even if the panel is laid in a stretch. That is, the conventional joist can be completely abolished. The fact that the joists can be abolished means that the material costs are reduced and the number of construction steps can be reduced.
