293906).

In such a floor heating panel, hot water flows through a hot water circulating pipe, and heat of the hot water is transmitted from the hot water circulating pipe to a heat equalizing plate. It is configured to spread evenly and heat over the surface.

As an example of the floor heating panel integrated with the surface material, as shown in FIG. 11, a hot water circulation pipe (r) is formed in a meandering pipe groove (r) formed inside a substrate (t). p) is housed therein, and a floor heating panel (X) in which a connection end (u) of the pipe (p) projects downward is projected.

[0005] The floor heating panel (X) is constructed by installing a joist (q) on the floor base (S), and placing the female and female members of each panel on the joist (q).
The male parts (y1) and (y2) are joined, and nails or screws (n) are driven into the male parts (y2) and fixed to the joists (q). The connection end (u) of each hot water circulation pipe (p) is a pipe joint (q) at a location where the joist (q) of the lower space of the floor heating panel (X) formed by the joist (q) is cut off. w).

[0006] Another floor heating integrated panel (Z)
As shown in FIG. 12, there is an example having substantially the same configuration as described above except that the real parts (h1) and (h2) are provided instead of the female / male real parts.

The floor heating panel (Z) is constructed by a receiving member (j) which is installed on the floor base (S) below the real part (h1) (h2).
And the real parts (h1) (h2) are joined together by butting through the receiving member (j), and nails or screws (n) are attached to each real part (h1) (h2). It is fixed to the floor base (S) by driving. Then, the hot water circulation pipe (p) is connected to each other through connectors (v) provided at each connection end (u) in a space formed by cutting a part of the receiving member (j), That is.

[0008] However, the former floor heating panel
(X) required a lot of time to connect the joist (q) and the hot water circulation pipe (p).

In addition, the latter floor heating panel (Z) requires a lot of time to construct the receiving member (j), and the floor heating panel (Z) is fixed on the floor substrate (S) by: Since the end of the panel is a real part (h), each real part (h1) (h
2) had to be connected to the floor substrate (S) with nails or screws (n).

Next, the first pair of the above-mentioned two sheets is used.
The construction method of the floor heating panels (A1 ₁ ) (A1 ₂ ) will be described.

First, one floor heating panel (A1 ₁ ) is placed on the floor base material (S) at the position where it is positioned,
(a22 ₁₎ to be fixed by implanting nails or screws (n) and the like.

[0042] Then attract other floor heating panel (A1 _2), communicating connection portion which extends between these panels _{(A1 1) (A1 2)} (b10 1) (b10 2) connectors between Check the connections by (c1 ₁ ) and (c1 ₂ ), and then connect them to the respective panel bodies.

At this time, as shown in FIG. 6, each of the hot water circulation pipes (b1 ₁ ) and (b1 ₂ ) has a surplus in each of the expansion portions (a50 ₁ ) and (a50 ₂ ) of the respective pipe grooves (a5 ₁ ) and (a5 ₂ ). becomes the part is accommodated bent, the connecting stub portion (b10 ₁₎ (b10 ₂₎ and the connectors (c1 ₁₎ (c1 ₂₎ each piping groove is (a5 ₁₎ (a5 ₂₎ in the It will be stored.

Next, the female part of the other floor heating panel (A1 ₂ )
(a21 ₂ ) is replaced with the male part (a2) of the panel (A1 ₁ )
After fitting joined to 2 _1), Omi portion of the panel (A1 ₂₎ (a22 ₂₎
Is fixed to the flooring material (S) in the same manner as described above.

By repeating the above operations, for example, the pattern is laid in a pattern shown in FIG. 8 as an example.

Embodiment 2 As shown in FIG. 9, the floor heating panel (A2) of this embodiment is different from the floor heating panel (A1) of Embodiment 1 in that no connector is used for the communication connection portion (b21) and two panels are used. (A2 ₁ ) and (A2 ₂ ) are connected by one hot water circulation pipe (b2), and the connecting end of the connecting groove of the piping groove (a52 ₁ ) (a52 ₂ ) is as shown in the figure. The second embodiment is the same as the first embodiment, except that the first embodiment is expanded by adding a radius. Therefore, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

With the structure as shown in this example, a pair of floor heating panels (A2 ₁ ) (A2 ₂ ) can be constructed quickly without the labor of connecting the connectors, and in FIG. As shown in the figure, the hot water circulation pipe (b2) has room at the communication connection part (b21), and the communication connection part drawing end port (a52 ₁ )
Since (a52 ₂ ) is rounded and expanded, the panels (A2 ₁ ) and (A2 ₂ ) can be easily overlapped with each other without exerting excessive stress on the communication connection portion (b21). It is convenient. In addition, the figure number (a4) of the figure shows the back material (also used as a soaking plate) made of aluminum.

The construction of the floor heating panel (A2) of the present embodiment is the same as that of the first embodiment except that the step of connecting the connectors is unnecessary, and the description thereof will be omitted.

[0048]

According to the present invention, since the hot water circulation pipe connecting the panels can be housed in the panel, the panels can be fixed directly on the floor substrate without the need for joists or the like. Therefore, the construction time can be greatly reduced,
And the construction itself can be simplified.

Further, the panels can be configured so that hot water can be circulated between a pair of panels. In this case, a hot water circulating pipe connecting the two panels can be connected and separated via a connector. It is also possible to connect the panels with one continuous hot water circulation pipe, so that the entire length of the pipe has room for the panel. Also, no excessive stress is applied to the pipe, and no effort or time is required for packing, transportation, and construction.
