DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating laying body using hot water.

[0002]

2. Description of the Related Art FIG. 4 shows a heating tatami conventionally known as a floor heating laying body. The structure of a tatami floor a as a floor material thereof is as follows. The tatami floor a is provided with a first hollow laminated plate 1 made of a multilayer structure at the bottom thereof, and a heat insulating layer 2 made of bead foam resin on the surface of the first hollow laminated plate 1. A guide groove 4 for laying the hot water pipe 3 is formed in the heat insulating layer 2. The reason why the heat insulating layer 2 is formed of the bead foam resin in this manner is due to the problem of workability. That is, the foaming resin molding method includes a bead foam molding method and a continuous extrusion foam molding method. However, when the guide groove 4 is formed on the surface as described above, the bead foam molding method is advantageous. This is because, in the case of the bead foam molding method, the guide groove 4 can be integrally formed, but in the case of the continuous extrusion foam molding method, the guide groove 4 must be separately processed.

A first aluminum foil 5 is laid on the surface of the heat insulating layer 2 including the guide groove 4, and a hot water pipe 3 is laid in the guide groove 4 on which the first aluminum foil 5 is laid. After the hot water pipe 3 is laid, a second aluminum foil 6 different from the above is further spread thereon, and a second hollow laminated plate 7 is stacked on the second aluminum foil 6. The tatami floor a is constructed as described above, and a tatami table 8 is laid on the tatami floor a to form a tatami floor for heating. Then, the tatami mats are laid on floor boards (not shown). In the tatami mat for floor heating in this manner, the heat insulating layer 2 made of foamed resin is first,
In addition to maintaining sufficient strength between the two hollow laminated plates 1 and 7, the first and second hollow laminated plates 1 and 7 and the heat insulating layer 2 combine to maintain a cushioning property as a tatami mat.

[0004]

In the conventional tatami for floor heating as described above, when a person walks on the tatami mat,
There is a squeak. This sound was found to be caused by the rubbing between the surface of the bead foam resin of the heat insulating layer 2 and the first aluminum foil 5. In other words, the surface of the bead foam resin is considerably glossy, but since the surface is glossy in this way, a sound is generated when it is rubbed with the aluminum foil. In any case, this sound is quite annoying, and the demand for silencing was constant, but with the conventional floor heating laying body,
This problem could not be solved. An object of the present invention is to form a heat insulating layer by a bead foam molding method excellent in processability,
An object of the present invention is to provide a floor heating laying body that does not emit sound.

[0005]

According to a first aspect of the present invention, a floor material to be laid on a floorboard is a heat insulating layer formed of bead foam resin, and a guide formed on the heat insulating layer and laying a hot water pipe. It is assumed that the floor heating laying body is made of a groove and an aluminum foil laid on the surface of the heat insulating layer including the guide groove, and a surface material such as a flooring or a tatami mat is laminated on the heat insulating layer. Then, a feature is that a large number of convex portions are formed on the surface of the heat insulating layer, an aluminum foil is laid on the convex portions, and a surface material is laminated thereon. The second invention is characterized in that the convex portions formed on the surface of the heat insulating layer are elongated in a streak shape.
The third invention is characterized in that a lattice pattern is represented by a convex portion. And the floor heating laying body of the present invention can be used for so-called flooring and tatami. Further, a surface material such as a flooring or a tatami mat may be directly laid on the aluminum foil laid on the heat insulating layer, or another member such as a cushion material may be interposed between them. In any case, the present invention can be applied to any structure in which an aluminum foil is laid on a heat insulating layer formed of bead foam resin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIGS. 1 to 3 relates to a tatami mat for floor heating. That is, the first hollow laminated plate 1, the heat insulating layer 2 made of bead foam resin, the first and second aluminum foils 5, 6, and the second hollow laminated plate 7 are laminated in this order. further,
The hot water pipe 3 is laid in the guide groove 4 formed in the heat insulating layer 2, and a tatami mat 8 as a surface material of the present invention is laid on the surface of the second hollow laminated plate 7. The most significant feature of the embodiment of the present invention is that a protrusion 9 is formed on the surface of the heat insulating layer 2. As shown in FIG. 3, the projections 9 are elongated in a streak shape and run vertically and horizontally on the surface of the heat insulating layer 2 to form a lattice pattern.

As described above, since the lattice-shaped convex portions 9 are formed on the surface of the heat insulating layer 2, when the first aluminum foil 5 is laid on the surface of the heat insulating layer 2, as shown in FIG. Aluminum foil 5
Rises up by the protrusion 9. Since the first aluminum foil 5 rises from the surface of the heat insulating layer 2 as described above, the contact area between the surface of the heat insulating layer 2 and the first aluminum foil 5 is reduced. If the contact area between the two is reduced, no sound is produced even if they are rubbed. And, even in the experimental results, the conventional sound was not generated at all. In addition, when the tatami mat for floor heating is used for a long period of time, the protrusions 9 gradually collapse. However, no matter how long they are used, the protruding part is not completely flattened, but remains at a certain height. When the peak of the convex portion 9 becomes low, the first aluminum foil 5 comes into close contact with the convex portion 9 as shown in FIG. If the first aluminum foil 5 comes into close contact with the convex portion 9, the first aluminum foil 5 is difficult to move, so that even if a person walks on the tatami, there is almost no sound.

As described above, when the height of the convex portion 9 is sufficiently maintained, or when the convex portion 9 becomes old and the convex portion 9 becomes low, the heat insulating layer 2 and the first aluminum foil 5 are connected to each other. It is possible to prevent slipping and completely prevent the generation of sound. In this embodiment, the convex portion 9 is elongated in a streak shape, and the convex portion 9 is formed on the surface of the heat insulating layer 2 in a lattice pattern composed of the convex portion 9. However, the convex portion 9 is formed only in one direction. You may make it run. Alternatively, many small protrusions 9 may be formed so that the surface of the heat insulating layer 2 becomes uneven.

[0009]

According to the floor heating laying body of the present invention, the heat insulating layer is made of beaded foam resin, and the processing cost can be kept low. There is no sound.
