BACKGROUND OF THE INVENTION
The present invention relates to a folding floor heating panel in which a hot water tube (pipe) is provided in a panel plate and an aluminum sheet is bonded to the upper surface.
[0002]
[Prior art]
FIG. 6 shows a conventional folding floor heating panel. In the case of the floor heating panel 100 having such a configuration, since it is normally produced in a factory, in consideration of transportability and storage to the construction site, it is usually a foldable type in which several panel plates 100a are combined. It has become. For this reason, when the panel board 100a is folded as it is in the so-called transboundary portion 103 where the hot water tube 101 straddles the adjacent panel board side, the hot water tube 101 also expands in a 180 ° U shape together as shown in FIG. Will do. As a result, since the hot water tube 101 is broken or crushed at the expanding portion 101a, various ideas that do not force the folding are made.
FIG. 7 shows an example of such a device. When the number of the hot water tubes 101 is four, the middle of each two is formed as a folded portion between the panel plates 100a, and the hot water tubes 101 cross the border in this folded portion. In FIG. 7, the number of the upper and lower portions is divided into two, and the hot water tube 101 is configured so as to be inclined from the linear direction only in the cross-border portion 103.
[0003]
When configured in this way, when the panel plate 100a is folded, the cross-border portion 103 of the hot water tube 101 is also U-shaped at the end of the panel plate 100a as shown in FIG. The bent portion 101a of the hot water tube 101 is exposed. As a result, the spreading portion 101a may be damaged during transportation or construction.
FIG. 9 shows another contrivance. The U-turn portion of the hot water tube 101 at both ends of the panel plate 100a is formed as a separate plate 100b, and the separate plate 100b is configured to be detachable and folded. In some cases, as shown in FIG. 10, by removing the separate plate 100b, as shown in FIG. 11, a degree of freedom is imparted to the expanding portion 101a of the hot water tube 101 so as not to be forced.
[0004]
However, each of the conventional examples described above has the following problems.
1. When part of the panel plate or hot water tube is removed and folded, it takes time and labor to pipe the tube at the site or to re-install the heat dissipation sheet.
2. Further, since the tube is exposed and packed and transported, there is a risk of damaging the tube not only during transportation but also when the package is opened and stored before construction on site.
3. In the type in which only the tube of one R portion is connected, the tube may be damaged due to the load of the folded portion.
[0005]
[Problems to be solved by the invention]
The present invention is to improve the drawbacks of the conventional folding hot water panel having these drawbacks, and its purpose is to allow the hot water tube to be bent smoothly at the folding portion and to warm water from the outside of the panel plate. It is to provide a hot water panel devised so as not to expose the circular portion of the tube.

Further, in the adjacent panel plate, a tube reversal accommodation sub-groove is formed in the opposite direction to the tube reversal accommodation main groove. It is.
[0007]
Furthermore, the invention according to claim 2 is characterized in that, in claim 1, the inclination angle of the hot water tube housing groove is set to 20 ° to 40 ° with respect to the longitudinal direction of the panel plate. It is.
If the inclination angle of the hot water tube housing groove is out of the range of 20 ° to 40 °, it is impossible unless the length of the panel plate in the longitudinal direction is limited, and it cannot be applied except for a special shape.
[0008]
Furthermore, the invention according to claim 3 is characterized in that, in claim 1, the circular portions of the tube reversal containing main groove and the containing sub groove are set within a range of R30 to 70. is there.
If the range of R30 to 70 is exceeded, it is impossible unless the width of the panel plate is controlled, and applications other than those with special shapes cannot be applied.
[0009]
Further, in the invention described in claim 4, in claim 1, 2 or 3, the piping layout of the hot water tube in one panel plate is inclined at the center portion, and the U-turn portions at both ends are the panels. The center portion of the plate is line-symmetric and R is formed with the same span.

【The invention's effect】
As described above, the present invention pipes (lays out) the hot water tube so as to be inclined with respect to the panel, and the inclined hot water tube is bent into the tube receiving groove at the portion where it crosses the adjacent panel plate side. When the panel plate is folded, the inverted portion of the hot water tube is along the recess formed by the main housing groove and the sub-groove when the sub-groove is provided on the side of the panel plate adjacent to the tube reversing main housing groove. Because it is circular and fits, the reversal angle of the hot water tube is gentle and is not exposed from the edge of the panel board.
As a result, the following effects are obtained.
1. There is no risk of damage during transportation or construction.
2. Panels and tubes are integrated, so there is no need to rework piping and heat dissipation sheets on site.
3. By storing and protecting the tube of the folded portion in the panel, it is possible to prevent the tube from being damaged.
4). By having the folded portion in the straight portion, the folded portion and the tube can be crossed at a natural angle at a long distance.
5). Since the load at the folded part does not concentrate on the tube, the risk of tube breakage is low.
6). Diagonal piping increases the density of the central portion of the piping pattern, increases the thermal efficiency of the central portion that is frequently used, and improves usability.
7). The reversal of the hot water tube is performed smoothly, and since this reversal portion is still in the groove, the reversal portion does not force the hot water tube.
