[0005]

In order to achieve this object, according to the first aspect of the present invention, rectangular panel portions having different lengths are arranged adjacent to each other with their width directions being the same. arrangement, and in which each panel parts are connected foldably to each other by a flexible surface material, between each panel portion adjacent to said width direction, the position is the length of the end portion in the longitudinal direction Since they are arranged so as to be different in the direction, the seam of each panel portion does not become a continuous straight line as in the conventional case described above,
Therefore, it is possible to prevent the panel from being bent from the joint at the time of transportation or the like as much as possible without providing a reinforcing material such as a small joist.

According to the second aspect of the present invention, the panel portion is composed of two types of panel portions, namely, a short panel portion having a short length and a long panel portion having a long length. Compared to those that use more than one type of panel part,
As the number of types of panels is small, the cost can be reduced in the manufacturing process, and the arrangement of short and long panels is reversed between adjacent panels in the width direction. As a result, the joint of the long and short panel portions does not continue between the panel portions adjacent in the width direction, and it is possible to prevent the panel portion from being bent.

According to the third aspect of the present invention, an end panel portion having substantially the same thickness as the panel portion and having a width approximately twice the width of the panel portion is provided. At both ends in the length direction of the panel portion, since it is configured to be arranged between two panel portions adjacent to each other in the width direction, when constructing a floor heating panel,
By embedding and piping the heat medium flow pipe in the curved concave groove provided in the end panel portion, it is possible to prevent the bending of the curved heat medium flow pipe portion from being extremely bent, and to reduce the piping of the heat medium flow pipe. Can be performed well.

According to the invention described in claim 4, the end panel portion extends between two panel portions adjacent to each other in the width direction at one end and the other end in the length direction of the panel portion. Since it is configured so that it can be arranged,
The end panel portions are connected while reinforcing between two adjacent panel portions. And since the end panel part which connects and reinforces between the two panel parts connects the two adjacent panel parts in directions different from each other at one end and the other end in the longitudinal direction of the panel part, The end panel portion will prevent bending from the joint between the panel portions adjacent in the width direction, and in cooperation with claim 1, in addition to the bending in the length direction of the panel portion, the end panel portion will not bend in the width direction. Can be prevented from being bent.

According to the fifth aspect of the present invention, since the surface material is made of the aluminum foil for soaking, the surface material for connecting each panel portion is made of the aluminum foil for soaking. It can be used both, and it is not necessary to lay aluminum foil for heat equalization on the surface of the panel part at the time of construction. And since the said panel part is comprised from a rigid polystyrene foam, the intensity | strength is large compared with the conventionally used polyethylene foam and the polystyrene foam, and the panel part with the large intensity | strength is used. As described in claim 1, by preventing the panel portion from being bent in the longitudinal direction, the conventionally required reinforcing joist can be eliminated, and the cost due to the abolition of the joist can be eliminated. It is possible to prevent not only the down, but also the discomfort when using the floor heating panel. In other words, in floor heating panels that used small joists as in the past, when walking on the upper surface of the floor finishing material such as flooring, the sinking amount of floor finishing material at the location where Differently, the difference in foot feeling gives pedestrians an unpleasant feeling. However, by eliminating the small joists, the sinking amount of the floor finishing material becomes substantially uniform, and the pedestrian is not uncomfortable.
