Description

[Detailed description of the invention] This invention relates to a floor heating panel that measures floor heating by conducting a heat medium such as hot water.

In this kind of floor heating panel described above, the heat transfer pipe is embedded in the heat insulating material. A heat transfer pipe consists of a main pipe and branch pipes branching from the main pipe. In a normal case, as shown in FIG. 1, only the connecting end 102 of the main pipe 101 is connected to the panel main body 10 for connection operation.
Exposed outside of 3. However, in floor heating panels with such a structure, when inspecting the heat transfer pipes of the finished product for leaks, it is necessary to
Regarding the connection part with 1, it is necessary to make the part visible by cutting away the heat insulating material, which poses problems such as impairing the reliability of the test and leaving scratches from the test.

An object of the present invention is to provide a floor heating panel that allows inspection of heat transfer pipes for leaks, etc., to be easily carried out without damaging the heat insulating material or the like.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The floor heating panel as an application example of the present invention shown in each of the figures after FIG. 2 is a rectangular flat panel formed by integrally constructing a heat insulating layer 2 filled with a heat insulating material on the back side of a surface steel plate 1 which is a surface structure. A heat medium pipe 4 through which a heat medium such as hot water is conducted is built into a panel main body 3 having a shape. The heat medium pipe 4 has two main pipes 5 that serve as an outgoing pipe and a return pipe, and a panel body 3 that branches from the main pipe 5.
It consists of branch pipes 6 meandering inside, each fixed to the back surface of the front steel plate 1 with aluminum tape 7, a retainer, etc., and embedded in the heat insulating layer 2 by filling with heat insulating material. Main pipe 5 in heat medium pipe 4
The connection end 5A is connected to the heat medium supply pipe of another floor heating panel (such as the main pipe connecting to the boiler).
This is the connection end with the panel body 3, and is exposed in the notch portions 8 formed at the two left and right corners of the panel body 3. The branch pipe 6 is in the form of a pipe that branches off from the main pipe 5 and returns to the main pipe 5, and the two connection parts 6A to the main pipe 5 are exposed in the notch part 8 together with the connecting end 5A of the main pipe 5. ing. The two cutout portions 8 of the panel body 3 are rectangular as shown in the figure, and a rectangular outer cover 9 is fitted therein in order to measure the flatness of the heating plane when constructing the floor heating panel. Outer cover 9
has a size and shape corresponding to the notch part 8, and is screwed to the mounting piece 10 provided in the notch part 8 from the surface side, so that the notch part 8 is filled and the part is flush with the surface of the surface steel plate 1. It should be flat. Inside this outer cover 9, there is an inner cover 11 which is about half the size of the outer cover 9 and which covers a part of the notch part 8 together with the connecting part 6A of the branch pipe 6 to the main pipe 5. It is attached as an attachment. That is, with the inner cover 11 attached and the outer cover 9 removed, the connecting end 5 of the main pipe 5 is
A connection operation is possible, and with both the outer cover 9 and inner cover 11 removed, the connection point of the main pipe 5 and the connection part 6A of the branch pipe 6 can be inspected for leaks, etc.
This can be done while directly viewing the relevant part.
Note that reference numeral 12 in the figure is a notch formed on the side of the inner cover 11 and outer cover 9, into which the main pipe 5 and branch pipe 6 are accommodated when installed.

However, in this floor heating panel, since the connecting portion 6A between the main pipe 5 and the branch pipe of the heat medium pipe 4 is exposed at the notch part 8 of the panel body 3, the heat medium pipe 4 must be inspected for leaks, etc. , can be carried out without manipulating the heat insulating layer 2, and the connecting portion 6A can be directly observed, so the inspection is highly reliable. In addition, for maintenance and inspection after construction, only the outer cover 9 can be removed as necessary.
Alternatively, the main inspection points regarding the piping can be exposed simply by removing both the outer cover 9 and the inner cover 11, so that inspection can be carried out easily and reliably.

As is clear from the above-mentioned embodiments and explanations, the floor heating panel of the present invention is suitable for areas where inspection and testing of heat medium pipes that conduct heat medium such as hot water are required, that is, the connection area of branch pipes to the main pipe. is exposed in a notch formed in the panel body, and
Since the connecting part of the branch pipe is covered with an inner cover, and the connecting end of the inner cover and the main pipe is covered with an exposed outer cover, it is possible to inspect for leaks at the connecting part of the branch pipe of the heating medium. This can be easily and reliably carried out by simply removing the outer cover and inner cover without any manipulation of the panel body (such as cutting away insulation material, etc.), and maintenance of heat transfer pipes after construction is easy.・Not only does it have the advantage of being easy to inspect, but it also allows you to connect the main pipe with the inner cover attached.
