5 to 5. FIG. 1 is a perspective view of a hot water floor heating panel, FIG. 2 is a perspective view of a reinforcing plate, FIG. 3 is a sectional view showing a main part of the hot water floor heating panel, and FIG. 4 is a sectional view schematically showing a hot water floor heating panel. 5 is a plan view showing a main part of the hot water floor heating panel.

As shown in FIG. 4, the hot water floor heating panel 1 has a built-in hot water pipe 8, a base material 5, a frame material 11 formed at the peripheral end of the base material 5, and a laminate on the surface thereof. The surface layer material 4 is provided. The surface layer material 4 is attached via a heat equalizing material (not shown) such as aluminum foil. In addition, the frame material 11
A fitting groove 12 is formed on the outer side surface of the housing 11. The fitting groove 12 can be provided with a clerk 13 for connecting the floor heating panels 1 to each other. The hot water floor heating panel 1 also includes a reinforcing paper 7 bonded to the back surface with an adhesive.

In the hot water floor heating panel 1, a pipe tunnel 3 for drawing in the inter-panel feed pipe 9 connected to the hot water pipe 8 is formed inside the base material 5. The inter-panel feed pipe 9 has a plurality of floor heating panels 1 installed.
The hot water pipes 8 are connected to each other.

The hot water floor heating panel 1 is provided with a surface layer piece 14 having a removable surface layer on a part of the surface layer material 4. When the surface layer piece 14 is opened, a connection space 10 having an open top is formed. To do. The hot water floor heating panel 1 has a connection space 10 and a piping tunnel 3
Panel-to-panel feed pipe 9 and hot water pipe 8 inserted inside
The pipe can be connected to the connection end of the. The panel-to-panel feed pipe 9 has an L-shaped joint pipe connected to the end of the panel-to-panel feed pipe 9 as a joint fitting in order to facilitate the pipe connection, and this joint pipe is the tip of the hot water pipe 8. It connects to the connection part of the part. In addition, in the hot water floor heating panel 1 of this embodiment, four end portions of the hot water pipes 8 are provided in the connection space 10, and the hot water floor heating panel 1 serves as an entrance and an exit of a hot water outward path and an entrance and an exit of a return path respectively.

In the hot water floor heating panel 1, a reinforcing plate 2 is fitted on the inner wall 6 of the piping tunnel 3. As shown in FIGS. 2 and 3, the reinforcing plate 2 has a substantially gate shape in cross section. The reinforcing plate 2 includes a plate-shaped top piece 21 and side pieces 22 hanging from both end edges of the top piece 21.
And a leg piece 23 extending inward from the lower end of the side piece 22. The reinforcing plate 2 includes a top piece 21 and a side piece 22.
Since the outer edge of is fitted into the inner wall 6 of the tunnel 3 for piping and the leg pieces 23 are provided, it has strength against impact from above. The reinforcing plate 2 is preferably made of metal or plastic having strength, and above all, stainless steel is preferable from the viewpoint of having a small thickness and maintaining strength. For example, in the hot water floor heating panel 1 in which the pipe tunnel 3 having a width of 45 mm and a height of about 8.5 mm is formed, the reinforcing plate 2 may be made of stainless steel having a wall thickness of 0.8 mm.

The front end 24 of the reinforcing plate 2 on the inlet side is arranged substantially flush with the outer edge 15 of the hot water floor heating panel 1. The reinforcing plate 2 is housed in such a state that the front end 24 on the inlet side thereof projects into the fitting groove 12. The reinforcing plate 2 has a length (reference A) in which the length (reference L) shown in FIG. 2 exceeds the line 12a in the groove of the fitting groove 12 from the end of the connection space 10 shown in FIG. Has become. Since the front end 24 of the reinforcing plate 2 on the inlet side of the hot water floor heating panel 1 projects into the fitting groove 12, a fitting 13 may be attached to the fitting groove 12 at this location. Can not. The reinforcing plate 2 is housed in a state in which the worker 13 is prevented from being caught at the entrance of the piping tunnel 3. As a result, the hot water floor heating panel 1 is
At the time of construction, hire the entrance of the piping tunnel 3
It doesn't block by mistake.

The position where the front end 24 of the reinforcing plate 2 on the inlet side is arranged should not extend beyond the outer edge 15 of the hot water floor heating panel 1, and may be beyond the groove line 12a.

Since the above-mentioned hot water floor heating panel 1 houses the reinforcing plate 2, there is no need to perform work for reinforcing the piping tunnel 3 at the time of construction, and the entrance of the piping tunnel 3 is actually employed. Blocking with 13 can be prevented. The hot water floor heating panel 1 can be easily constructed.

Next, a second embodiment of the present invention will be described with reference to FIGS.
8 will be described. FIG. 6 is a cross-sectional perspective view showing the inner wall of the pipe tunnel, FIG. 7 is a perspective view of the reinforcing plate, and FIG. 8 is a cross-sectional view showing a main part of the hot water floor heating panel. Only points different from the above embodiment will be described.

As shown in FIG. 6, the hot water floor heating panel 1 has a groove 32 formed in the side wall 31 of the pipe tunnel 3. The reinforcing plate 2a used in the hot water floor heating panel 1 is, as shown in FIG.
And a side piece 34 extending downward from both end edges of the ceiling piece 33 and protruding outward in a dogleg shape in a cross-sectional view, and a leg piece 35 extending inward from the lower end of the side piece 34. Has been done.
As shown in FIG. 8, the reinforcing plate 2a is engaged by inserting the protruding portion 36 of the side piece 34 into the concave groove 32 of the side wall 31. Further, by engaging the reinforcing plate 2a in the manufacturing process of the hot water floor heating panel 1, the protruding portion 36 of the side piece 34 is made to come into contact with the recessed groove 3 from the inlet side of the pipe tunnel 3.
It can be done by sliding along 2.

Since the hot water floor heating panel 1 contains the reinforcing plate 2a, the work for reinforcing the pipe tunnel 3 is not required at the time of construction, and the entrance of the pipe tunnel 3 is employed. Blocking with 13 can be prevented. Further, the reinforcing plate 2 can be easily attached in the manufacturing process of the hot water floor heating panel 1.

[0020]

Since the hot water floor heating panel of the present invention accommodates the reinforcing plate, the work for reinforcing the pipe tunnel is not required during the construction, and the entrance of the pipe tunnel is employed. You can prevent it from being blocked with fruit. As a result, in the hot water floor heating panel, the pipe tunnel is reinforced, and the construction work can be facilitated.
