Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water type floor heating panel for heating floors by conducting hot water to a hot water pipe embedded in the interior.

[0002]

2. Description of the Related Art A conventional hot water type floor heating panel has a structure as disclosed in, for example, Japanese Utility Model Laid-Open No. 62-100413. That is, as shown in FIG. 2, a board 2 which is a heat insulating substrate in which a hot water pipe 1 for conducting hot water is embedded in a meandering groove formed on the front side, and a surface of the board 2 are bonded with an adhesive 3. The surface plate 4 constitutes a heat transfer surface. The hot water pipe 1 has an exposed lead-out portion 5 for connection with another floor heating panel, flow path switching means, and the like. As shown in the enlarged view of FIG. 3, the lead-out portion 5 is configured such that the hot water pipe 1 of the lead-out portion 5 can be slightly moved for convenience of construction such as connecting operation. Specifically, the groove bottom of the board 2 of the part has a downward slope 6 toward the end face,
A gap 7 that allows movement is formed below the hot water pipe 1.

In the hot water type floor heating panel having the above structure, the entire surface plate 4 is heated by the conduction of hot water to the hot water pipe 1 to perform the floor heating function. At the time of construction, since the lead-out portion 5 of the hot water pipe 1 is not restricted and can move, the connection operation can be performed relatively easily even in a narrow place.

[0004]

In the above-mentioned conventional hot water type floor heating panel, the connection operation of the hot water pipe is facilitated by the gap, but when the lead-out portion moves due to the connection operation or the like, this portion is separated from the adhesive. In addition, there is a problem to be solved such that contact pressure is generated and an abnormal noise is generated to make a person feel structurally weak.

The present invention has been made in order to solve such a conventional problem, and an object thereof is to obtain a hot water type floor heating panel in which a strange noise is hardly generated even by the movement of the opening portion. .

[0006]

The hot water type floor heating panel according to the present invention is connected to the opening portion of the hot water pipe for convenience of connection operation, and the opening portion is provided between the board of the hot water pipe and the lower side of the hot water pipe. With a gap that allows movement,
A ribbon made of a thin buffer material is interposed between a hot water pipe corresponding to the gap and an adhesive agent for adhering the surface plate.

[0007]

In the hot water type floor heating panel according to the present invention, the ribbon functions as a buffer even when the lead-out portion moves, so that the ribbon is not peeled off or pressed against the adhesive.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of the essential parts of a hot water floor heating panel showing an embodiment of the present invention.

The hot water type floor heating panel of this embodiment is characterized by the construction related to the lead-out portion of the hot water pipe, and the other basic structure is the same as the conventional example shown in FIG. Therefore, the same parts as those of the conventional example will be described by using the same reference numerals. The hot water type floor heating panel of the illustrated example is a board 2 which is a heat insulating substrate in which a hot water pipe 1 for conducting hot water is embedded in a meandering groove formed on the front side,
A surface plate 4 constituting a heat transfer surface is adhered to the surface of the board 2 with an adhesive 3. The hot water pipe 1 has two or more exposed outlet portions 5 for pipe connection with other floor heating panels and connection of flow path switching means (not shown). As shown in an enlarged view in FIG. 1, the lead-out portion 5 is configured such that the hot water pipe 1 of the portion can be slightly moved for convenience of construction such as connecting operation. Specifically, the groove bottom of the board 2 of the relevant portion has a gentle downward slope 6 toward the end face, and a gap 7 that allows movement is formed below the hot water pipe 1. Between the hot water pipe 1 corresponding to the gap 7 and the adhesive 3 that adheres the surface plate 4, a thin buffer material, for example, a metal plate such as aluminum or iron, or a thin plate, or a cushion material such as urethane foam or rubber. A ribbon 8 made of is interposed. The length of the ribbon 8 corresponds to the gap 7, and the width thereof is the adhesive 3 between the surface plate 4 and the board 2.
The groove width of the board 2 + 1
0 mm or less.

In the hot water type floor heating panel having the above structure, the entire surface of the surface plate 4 is heated by the conduction of hot water to the hot water pipe 1 to perform the floor heating function. At the time of construction, since the lead-out portion 5 of the hot water pipe 1 is not restricted and can move, the connection operation can be performed relatively easily even in a narrow place. Even if the lead-out portion 5 moves due to a connection operation or the like, the cushioning action of the ribbon 8 does not cause peeling and contact pressure from the adhesive 3 at this portion. There is no strange noise that makes you feel hugged, so you can feel a sense of security.

When the ribbon 8 is made of a cushioning material, an adhesive layer may be provided on one side of the ribbon 8 to improve the efficiency of the assembling work.

[0012]

As described above, according to the present invention, although the lead-out portion of the hot water pipe is not restricted and can move,
Even if the lead-out portion moves due to connection operation, etc., the cushioning action of the ribbon does not cause peeling or contact pressure with the adhesive in this portion, so that the structural fragility caused by this can be felt. The occurrence of such abnormal noise is almost eliminated, and a sense of security can be provided.
