Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a heating fluid circulation type floor heating panel which is installed mainly between joists of a wooden structure and can also serve as a floor plate.

[Conventional technology]

Conventionally, as an apparatus used for such floor heating, for example, a flat rectangular frame-shaped panel main body formed by bending four sides of a rectangular iron plate is internally provided with a heating fluid conducting pipe such as hot water or steam in a meandering shape. In addition, by filling the space inside the panel with a heat insulating material and embedding the conduction pipe in the heat insulating material, the heat of the heating fluid flowing in the pipe was prevented from radiating from the bottom surface of the panel. The thing of the structure is known.

[Problems to be solved by the device]

By the way, since floor heating can realize a comfortable heating effect without excessively raising the indoor temperature by keeping the floor of the floor at an appropriate temperature, it is rapidly becoming popular in general wooden constructions in recent years.

However, since the floor heating panel having the above-mentioned conventional structure is prepared on the assumption that it is laid on the floor surface of concrete construction or the like, when it is laid on a wooden building, it is installed between the joists as a floor board. It is not possible to do so in terms of strength, and since the structure of the panel main body that constitutes the outer shell of the pipe is simply formed into a flat rectangular shape, it is necessary to change the floor structure of the building itself to fix it to the joist. In fact, it is almost impossible to use it as a floorboard.

For this reason, conventionally, the panel is placed on the already laid floor plate, but in this case, the floor has a double structure of the floor plate and the panel, which is uneconomical and the floor is installed with the panel. Since it is necessary to make the surface flush with the corridor or the floor surface of the adjacent room, it is necessary to devise a construction method, which leads to high costs.

In addition, when the panel is installed in a Japanese-style room, a tatami mat is laid on the panel. Therefore, if liquid leaks from the connection between the conducting pipes of a plurality of panels, the tatami mat and the floorboard will be damaged. The problem arises.

The present invention has been made in order to solve such a problem, and it is economically excellent in that it can be installed between the joists of a wooden building as a floor board and is economically excellent. The purpose is to provide a floor heating panel that can prevent damage to tatami mats, etc.

Since (3) is provided, both flange portions (3) and (3) are joists (J) by a very simple work of just inserting the panel main body (1) between the opposing joists (J) (J). It is received on the upper surface of (J), whereby the panel main body (1) can be erected between joists (J) and (J) with the panel (1) being accurately positioned. Therefore, in addition to eliminating the conventional positioning trouble, more importantly, when the panel main body (1) is installed between the joists (J) (J), the flat plate portion (2)
Since it is the one that exerts the function as a normal floor board as it is, it is not necessary to lay a floor board in advance unlike the conventional one, and the remarkable effect that the economical and workability is significantly improved compared to the conventional one. Was played.

Further, the panel main body (1) has flange portions (3) (3).
Vertical side plate parts (4) (4) are integrally provided at both ends of
A heat-insulating belt-like elastic body (14) that is in close contact with joists (J) (J) over the entire length of the outer side surface of the vertical side plate portions (4) (4)
Since the (14) is attached, when the panel main body (1) is attached between the joists (J) and (J), the outer band-shaped elastic body (14)
The (14) closely adheres to the inner surface of each joist (J) (J) without any gap, and not only fulfills the heat retaining function of the heating fluid, but also the heating fluid flowing through the pipes (7), (7), ... (7) (7) Even if it leaks from the connection part between (7) and (7), there is a risk that the leaked heating fluid may damage the tatami mat or rug laid on the flat plate part (2) of the panel main body (1). To be prevented. Even if there is some error in the joist (J) (J) spacing, the error is absorbed by the elastic deformation of the band-shaped elastic bodies (14) (14), and the vertical side plate portion of the panel main body (1) is absorbed. (4) There is no fear that a gap will be created between (4) and joist (J) (J).

Further, the heating fluid conducting pipes (7) and (7) fixedly attached to the lower surface of the flat plate portion (2) of the panel main body (1) in a close contact state.
Is a space portion (S) formed between the lower surface of the flat plate portion (2) of the panel main body (1) and the facing surfaces of both side vertical side plate portions (4) and (4).
A heat insulating film (12) is stretched over the entire lower surface of the opening of the space (S) which is embedded in the heat insulating material (13) filled with the heat insulating material (13). Therefore, the heat of the heating fluid circulated in each of the conduction pipes (7) and (7) is effectively prevented from being diffused from the bottom portion of the panel main body (1) by the heat insulating material (13) and the heat insulating film (12). By doing so, it is possible to achieve the floor heating with high heat efficiency by radiating on the floor surface with almost no heat loss through the flat plate portion (2) of the panel main body (1), which has never been possible before. It became something to do.
