DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment shown in FIGS. 1 to 6 is a heating panel assembly 1 which is mainly laid on a floor and used for floor heating for heating by circulating a heat medium such as hot water. It is about. The heating panel assembly 1 has a flat rectangular shape (750 × 1470 × 12 mm corresponding to the size of the tatami mat).
The heating panel 3 is provided with a heat medium pipe 2 made of a flexible cross-linked polyethylene or the like for conducting a heat medium to a disk-shaped panel having a thickness of many rectangles, but a planar shape may be a square. In the state where the heat medium pipes 2 are connected, three or more of the side surfaces are connected in the X direction and the Y direction, which are substantially orthogonal to each other on a plane, to form a flat plate body. In the present embodiment, as shown in FIG. 1, a heating panel assembly 1 for a six-tatami floor, which is composed of six heating panels 3 having two sheets in the Y direction and three sheets in the X direction, is described as an example. I do.

Each of the six heating panels 3 constituting the heating panel assembly 1 has substantially the same plane area (750
× 1470 mm), and a heating medium pipe 2 is buried in a series of pipe grooves recessed on a board-shaped panel of a foamed polyethylene molded body as a base, and a meandering pipe is buried. It has a surface material having a property. In the heating panel 3 having two rows and three rows in the Y direction, the heat medium pipes are configured as a heat medium path of one system at a time in units of rows, and the heat medium pipes 2 form the connecting portions 4 on the short side surfaces to be joined. Connected. With this piping configuration, even if the plane area is large, the heating medium piping 2 has a parallel configuration, so that an increase in pressure loss can be prevented, and uniform heating can be performed. The heating panel 3 in the three rows in the X direction has a long side in which the central heating panel 3A and the heating panels 3 on both sides of the three panels in the lower first row shown in FIG. The heat medium pipe 2 is connected to form a connecting portion 4 at the side surface of the connecting member. The three heating panels 3 in the upper second row shown in FIG. 1 in the X direction do not have any relation to the heat medium pipes 2 only by abutment of the long side surfaces.

The heating panel 3A at the center of the first row is provided with a header 5 connected to an incoming pipe and a return pipe of a heating medium supply system (not shown). The heat medium is distributed in the medium path. In this sense, the heating panel 3A at the center of the first row is a master panel related to the circulation of the heating medium in the heating panel assembly 1, and the heating panel 3A including the header 5 for distributing the heating medium is hereinafter also referred to as the master panel 3A. I will. The heating panels 3 in the row including the master panel 3A are connected to each other by a connecting portion 4 of the heat medium pipe 2 on the long side of the joined side, and the two heating panels 3 in each row are joined in each row. The short sides are connected by the connecting portion 4 of the heat medium pipe 2.

The draw-out portions 6 of the adjacent heating panels 3 in the connecting portion 4 of the heat medium pipe 2 are staggered in a plane in a staggered positional relationship, and the entire connecting portion 4 including the draw-out portion 6 is held by the holding means 7. It is held so that it can be released. There is a discrepancy between the positions of the draw-out portions 6 of the heat medium pipes 2 of the adjacent heating panels 3, that is, the interval D on the plane of the draw-out portions 6.
May be set by maximizing the length of the short side of the heating panel 3, and the interval D is configured to be equal on both the short side and the long side.

The holding means 7 includes a connecting portion 4 of the heat medium pipe 2.
If the holding groove 8 for holding a pair of diagonally detachable retaining grooves (a paired structure of a forward side and a return side) is recessed, even if the retaining groove 8 is integrally formed on the front side of the panel, Although it may be configured to be detachable, it is easier to use a detachable configuration. In this case, as shown in FIG. 3, on the long side, a rectangular concave portion 9 including the drawn-out portion 6 of the heat medium pipe 2 of the heating panel 3 is formed, and is formed by the concave portions 9 of the adjacent heating panel 3. The holding means 7 as shown in FIG. 2 has a structure that can be fitted to the portion, and the heating panel 3 adjacent to the short side is
What is necessary is just to make the holding means 7 of the structure sandwiched between short sides of each other.

The number of components of the holding means 7 having such a different structure is increased as compared with the case where the holding means 7 is integrally formed. However, by forming the holding grooves 8 in line symmetry as shown in FIG.
The short-side side, the long-side side, and the left and right holding means 7 can all be shared, and cost increase can be suppressed.

The number of the heating panels 3 constituting the heating panel assembly 1 may be three or more. As shown in FIG. 6, a heating panel assembly 1 having a four-panel configuration and a heating panel having an eight-panel configuration are provided. It is also possible to form the aggregate 1. However, in the three-panel or four-panel heating panel assembly 1, the master panel 3A is arranged at the end of the row.

In the heating panel assembly 1 described above, by removing the connecting portion 4 of the heat medium pipe 2 from the holding means 7 and removing all the holding means 7, the heating panel assembly 1 shown in FIG. It can be folded into a laminate of the size of a flat area. In the folding, first, the heating panels 3 arranged in rows are overlapped so that the surfaces of the heating panels 3 overlap each other as shown in FIGS. 3 and 4. At this time, the connecting portion 4 of the heat medium pipe 2
In the state in which bending and bending can be tolerated by the length of the interval D between the extraction portions 6, the bending occurs with a slight twist, and the stress due to bending becomes extremely small.

When the heating panels 3 in a row are superimposed, the superposed heating panels 3 on both sides are alternately superimposed on the heating panels 3 superimposed on the master panel 3A, with the master panel 3A at the bottom. As in the case of the column folding, the connecting portion 4 of the heat medium pipe 2 is bent with a slight twist in a state where bending or bending can be allowed by the length of the interval D between the lead-out portions 6. And the stress due to bending becomes extremely small. Since it can be packed and transported or stored in this state, it is not bulky and its handling is easy.
At the time of construction, the master panel 3A is set at the lowermost position, and the position of the header 5 of the master panel 3A is adjusted to the piping position of the heat medium supply system from the boiler or the like, or the center or edge of the edge of the floor to be laid (see FIG. In the case of the four-sheet configuration shown in the figure, etc.), it is deployed in the reverse procedure to the folding method. By doing so, the connection between the master panel 3A and the heat medium supply system is easy, and the wall standing from the floor does not hinder the deployment, so that it can be laid down on the floor and it is very convenient. Will be able to do it. At the time of laying, the holding means 7 is attached, and the heat medium pipe 2 is fitted and held along the holding groove 8.
