DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel for heating a panel surface by flowing a warm fluid such as hot water through a pipe incorporated in a panel body.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional floor heating panel is composed of a panel body a and a pipe mat m incorporated in the panel body a. The panel body a
Is a finishing material 1 constituting the surface of the floor, and the finishing material 1
And a base material 2 adhered to the lower surface of the base material.
A pipe mat m is incorporated on the side. Pipe mat m
Is a pair of main pipes 3 and 4 with a circular cross section and a large diameter.
And a plurality of thin heat exchange pipes 5 connected to the main pipes 3 and 4. The heat exchange pipes 5 are arranged in a fine pitch to form a mat. And
The hot water supplied from one of the main pipes is guided to the other main pipe via a plurality of heat exchange pipes 5.

In such a pipe mat m, the main pipes 3 and 4 are respectively fitted in grooves 6 and 7 formed in the base material 2, and the heat exchange pipes 5 are respectively fitted in grooves 8 formed at equal intervals. I have. Then, after fitting the pipe into each groove, the finishing material 1 is attached with a heat transfer sheet made of aluminum foil or the like (not shown) interposed therebetween.

[0004] Joints 9 and 10 are fixed to both ends of the main pipes 3 and 4 located on the side surfaces of the base material 2, respectively. When a plurality of floor heating panels are arranged side by side, one of which is a male side and the other is a female side, these joints 9 and 10 are connected to the male joint or the female joint of one floor heating panel adjacent to each other. Are connected to the female joint or the male joint of the floor heating panel. With such a connection, the main pipes of the adjacent floor heating panels are communicated with each other, and hot water supplied from one of the floor heating panel main pipes is guided to the main pipe of each floor heating panel. The hot water supplied to the main pipe 3 or 4 of each floor heating panel passes through the heat exchange pipe 5 and is guided to the other main pipe 4 or 3.

[0005]

In the above-mentioned prior art, the following problems arise because the base material and the finishing material are integrated. That is, in recent years, the number of buildings constructed by the so-called prefabrication method in which floor panels, ceiling panels, and wall panels are assembled in a factory in advance, and unitized products are assembled on site is increasing. In a building using such a construction method, a base material is often installed on a floor panel which is unitized. Therefore, in the above-mentioned conventional panel in which the base material and the finishing material are integrated, the base material becomes extra. Therefore, it is conceivable to remove only the base material. However, since the base material 2 incorporates the pipe mat m, the base material 2 cannot be simply removed. Therefore, there has been a problem that this conventional panel cannot be directly applied to a building in which the base material is unitized.

On the other hand, since the pipe mat m is incorporated in the base material 2, the thickness of the base material 2 is reduced in this conventional example.
The thickest part of the pipe mat m, ie the joints 9,10
It is even thicker than the part. However, if the thickness of the base material 2 is made larger than that of the joints 9 and 10, the base material 2 becomes thicker as a whole, and the thickness of the floor heating panel itself increases. When the thickness of the floor heating panel is increased, a step is easily formed on the floor surface between the room where the floor heating panel is laid and the room where the floor heating panel is not installed. For this reason, it was sometimes impossible to apply it to a barrier-free house. An object of the present invention is to provide a thin and highly versatile floor heating panel that does not require a base material.

[0007]

According to a first aspect of the present invention, a pipe mat formed by connecting a plurality of thin heat exchange pipes to a main pipe having a flat cross section is embedded on the back side of a single panel body. A connecting pipe which is connected to the main pipe and constitutes a joint having a flat cross section is arranged so as to protrude in parallel with the panel body.

[0008] In a second aspect based on the first aspect,
An outer cylinder member incorporated in the connection pipe, an inner cylinder member insertable into the outer cylinder member, and a seal member provided between the outer cylinder member and the inner cylinder member, and a plurality of panel bodies are butted. When arranged side by side, the connection pipes forming a pair of joints facing each other are communicated by the inner cylinder member, while the seal member keeps the state between the inner cylinder member and the outer cylinder member sealed, The outer cylinder member and the inner cylinder member are relatively movable in the axial direction.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a panel body A made of one finishing material 11 with its back side facing up. Although not shown, a recess corresponding to the shape of the pipe mat M is formed on the back side of the panel body A,
The pipe mat M is inserted there. The pipe mat M is fixed by a heat equalizing plate 12 attached to the back surface of the panel main body A with an adhesive. In addition,
The heat equalizing plate 12 is made of a material having high thermal conductivity such as an aluminum sheet, and exerts a function of uniformly transferring the heat of the pipe mat M to the entire panel by bringing the pipe mat M into contact therewith.

The pipe mat M embedded in the panel main body A as described above is the same as the conventional example in that it comprises a pair of main pipes and a plurality of thin heat exchange pipes connected to these main pipes. In this embodiment, the sectional shape of the main pipe 13 is made flat as shown in FIG. In addition, as shown in the figure, the term “flat” includes not only a rectangle with rounded corners, but also an elliptical shape, a fan shape, and the like, and a shape whose thickness is relatively thinner than a circle.

Since the cross-sectional shape of the main pipe 13 is made flat as described above, the portion into which the main pipe 13 is fitted, that is, the groove formed in the panel body A can be made shallower. If the groove is made shallow, the thickness of the panel body A can be reduced while maintaining the strength of the panel body A. That is, according to this embodiment,
Even if the pipe mat M is inserted into the panel main body A, an increase in the thickness of the panel main body A can be suppressed. Since the main pipe 13 has a flat cross section, the main pipe is completely housed in the panel main body A.
The surface of the heat equalizing plate 12 attached to the back surface of the panel body A is flat. However, as shown in FIG. 1, connecting pipes 14 forming a joint are provided at both ends of the main pipe 13.
And only the connection pipe 14 is projected from the back surface of the panel body A.

FIG. 3 shows a pipe mat M as described above.
FIG. 6 is an enlarged cross-sectional view of a part where panel main bodies A each incorporating a. As shown, connection pipe 14
Is composed of a pipe portion 15 and a joint portion 16 and is arranged in parallel with the panel body A. Although not shown, the cross-sectional shape of the pipe portion 15 is made flat like the main pipe 13, the main pipe 13 is connected to one end of the pipe portion 15, and the joint portion 16 is fixed to the other end. The structure of the joint 16 will be described later in detail.

When the connection pipe 14 is connected to the main pipe 13, the connection pipe 14 projects from the back surface of the panel body A as a matter of course. However, since the connecting pipe 14 has a flat cross-sectional shape and is disposed in parallel with the panel body A, the amount of protrusion is much smaller than that of a pipe having a circular cross-section. Further, since the main pipe 13 and other parts are completely buried in the panel main body A, only a small part of the connection pipe 14 protrudes from the back surface of the panel main body A.

Since the connecting pipe 14 slightly protrudes from the lower surface of the panel body A, when laying this floor heating panel, the base material corresponding to the connecting pipe 14 is circulated, and the connecting pipe is placed there. 14 will be paid. In this way, it is necessary to go through the base material,
As described above, the projecting range is minimized and the projecting amount is minimized, so that the excavation work is also small. In this way, only a small amount of work is required, so that the workability when laying the floor heating panel can be maintained at the same level as before.

Next, the structure of the joint 16 of the connecting pipe 14 will be described with reference to FIGS. As shown in FIG. 4, the joint 16 incorporates a pair of outer cylinder members 19, 19 in a body 18 thereof, and forms annular recesses 20, 20 on the inner circumference at the distal end thereof. 20 incorporates O-rings 21 and 21 corresponding to the seal member of the present invention. Then, the inner tube portion 23 of the intermediate joint 22 constituting the inner tube member of the present invention is inserted into the outer tube member 19 incorporating the O-ring 21. That is, the intermediate joint 22 has inner cylindrical portions 23, 23 formed on both sides of the enlarged diameter portion 22a, respectively, and is connected to the joint portion 16 of one floor heating panel facing each other when a plurality of floor heating panels are arranged. The one inner cylinder 23 is inserted, and the other inner cylinder 23 is inserted into the joint 16 of the other floor heating panel (see FIG. 5). In this way, the main pipes 13 of the adjacent floor heating panels, that is, the pipe mats M can communicate with each other.

In this embodiment, a pair of outer cylinder members 1
Although nine and nineteen are used, the number of the outer cylinder members 19 is not limited to one set. Further, the cross-sectional shape of the flow path of the outer cylinder member 19 is not limited to a circular shape. That is, the number and shape may be set according to the flow rate through which the outer cylindrical member passes. However, when the cross-sectional shape of the channel is elliptical,
Accordingly, the inner cylindrical portion 23 of the intermediate joint 22 also needs to be elliptical.

When the inner cylinder 23 of the intermediate joint 22 is inserted into the outer cylinder 19, the inner cylinder 23 and the outer cylinder 1
9 is sealed by an O-ring 20. Moreover, the inner cylindrical portion 23 that can be inserted into the outer cylindrical member 19
By setting the dimensions of the O-ring 21 sufficiently long,
Thereby, the outer cylinder member 19 and the inner cylinder portion 23 can be relatively moved in the axial direction while maintaining the sealing property. In this manner, the outer cylinder member 19 and the inner cylinder portion 2 are maintained while maintaining the sealing property.
3 is relatively movable in the axial direction, so that even if there is a slight gap between adjacent floor heating panels, fluid does not leak from the main pipe 13 and the main pipe M of the pair of floor heating panels Can be kept in communication. That is, the position of the panel main body A can be shifted while maintaining the state where the main pipe M is communicated.

Therefore, even if the mating surfaces of the panels do not exactly fit due to dimensional errors or the like at the time of manufacturing the panels, the main pipes M can communicate with each other.
Further, even if the opposing panels are separated by the action of the external force, the main pipes M can be kept in communication with each other, and the function as the floor heating panel can be maintained. Furthermore, since the panel body A can be constructed while sliding after connecting the joints, the panel laying work becomes very easy.

According to this embodiment, since the base material is provided separately, the floor heating panel can be applied to a building having a structure in which the base material is attached in advance. Further, since the thickness of the entire panel is reduced by making the cross section of the main pipe M flat or the like, the step between the room where the panel is laid and the room where the panel is not installed can be eliminated. Therefore, the panel of this embodiment can be directly applied to a barrier-free house. On the other hand, since the joint portion is projected from the lower surface of the panel body A,
When laying panels, it is necessary to go through the base material. However, since the joint portion is also flattened to minimize the amount of protrusion, the work for digging the base material is small. Therefore, the workability at the time of laying the panel is almost the same as the conventional one. Therefore, the workability at the time of laying the panel does not deteriorate.

Further, since the pipe mat M is embedded in the panel body A which is a finishing material, the pipe mat M
Can be brought closer to the surface of the panel. By bringing the pipe mat M closer to the surface of the panel in this way, the thermal efficiency can be increased. Furthermore, if the intermediate joint 22 is removed, the joint does not protrude from the side surface of the panel body A, so that the packing operation is facilitated, and there is no problem that the joint is damaged during transportation. That is, conventionally, since the joint portion protrudes from the side surface of the panel main body, it is necessary to cover the portion with a cover or the like and pack it, which takes time and effort. Also, if there is a part protruding from the side of the panel body,
The part was caught during transportation and was sometimes damaged.

However, according to this embodiment, the intermediate joint 2
As long as 2 is removed, there is no portion protruding from the side surface of the panel main body A, so there is no such fear. In this embodiment, the joint pipe 14 protrudes from the back surface of the panel main body A. However, if the joint pipe 14 protrudes from the back surface of the panel main body A, the packaging work does not take much time.
Also, since the protruding part is the back of the panel body A,
There is almost no danger of the part being caught and damaged during transportation.

When the heat equalizing plate is attached to the panel body A, as shown in FIG.
May be applied more to the back surface 29 of the panel body A, and the adhesive 30 may be poured into the groove 27 for the heat exchange pipe 28 formed on the back surface 29 of the panel body A. The adhesive 30 is poured into the groove 27 in this manner, and the heat exchange pipe 28
By filling the gap between the heat equalizing plate 12 and the heat equalizing plate 12, the heat of the heat exchange pipe 28 can be efficiently transmitted to the heat equalizing plate 12. That is, the adhesive 30 for attaching the heat equalizing plate 12 to the panel body A
The thermal efficiency can also be increased by using the.

[0023]

According to the first aspect of the present invention, since the base material is separately provided, the floor heating panel can be applied to a building having a structure in which the base material is attached in advance. In addition, since the connection pipe forming the joint is projected from the panel main body, the thickness of the panel main body can be reduced. Therefore, the step between the room where the panel is laid and the room where the panel is not installed can be eliminated, and the present invention can be applied to a barrier-free house as it is.

According to the second aspect, the outer cylinder member and the inner cylinder member can move relative to each other in the axial direction while maintaining the state in which the outer cylinder member and the inner cylinder member are sealed by the seal member. The body can also be slid. Therefore, between the pair of butted panel bodies,
Even if gaps are created due to dimensional errors,
The main pipes facing each other can be connected without leakage, and the function as a floor heating panel can be maintained.
