Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underfloor laying part of a floor heating board which is improved so that heat conduction onto the floor is good.

[0002]

[Prior Art]

 In the underfloor laying part of the conventionally known floor heating board, a floor heating insulation board, in which a groove for pipe piping is provided in a meandering shape on a board made of thermoplastic resin, is installed on the floor base. Or a floor heating insulation board in which short pillar-shaped projections are arranged in a staggered pattern integrally with the board made of thermoplastic resin foam is laid on the floor base. There is.

[0003]

[Problems to be solved by the device]

 In the former case of the conventional underfloor laying section, it is easy to lay a heat conductive material in the groove in order to effectively transfer the heat radiation from the pipe to the floor material side, but the pipe size and piping pitch are preset. However, there is an inconvenience that is completely lacking in the flexibility to change the piping pattern on site.

The latter has flexibility in pipe size and pipe pitch when laying a pipe, but it is difficult to lay a heat conductive material on the lower surface of the pipe. Therefore, when a concrete floor is formed on a floor heating insulation board, concrete exerts a heat conduction effect and uniform floor heating is obtained, but when a wooden floor is formed on the floor heating insulation board. Has a problem that it is difficult to obtain uniform floor heating.

The present invention solves such a problem, and its purpose is to have flexibility in pipe size and pitch, which is convenient for piping work, and has good heat conduction to the floor. Therefore, it is to provide an underfloor portion of a floor heating board which is improved so as to achieve uniformity of floor heating.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the underfloor laying portion of the floor heating board, which is a feature of the present invention, is a board made of a thermoplastic resin foam, and short pillar-shaped projections are arranged in a staggered pattern integrally with the board. The floor heating board is laid on the floor base, and a pipe made of a thermoplastic resin coated with aluminum foil is laid on the floor heating board through the projections, and the aluminum foil is placed on the board. The floor covering is laid over it.

[0007]

[Action]

 If the pipes are laid on the floor heating board so that they are sandwiched between the adjacent protrusions, the pipes are supported and stabilized by each protrusion, while the pipes are covered with aluminum foil and the board is covered with aluminum. Since it is covered with the foil, the heat conduction to the floor is extremely good and the floor heating can be performed uniformly.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to FIG. 1 and FIG. 2. Reference numeral 1 is a floor base in a building, on which a thermoplastic resin foam board is mounted and has a short pillar shape integrated with the board. A floor heating board 2 in which projections 3 are arranged in a staggered manner is laid, and on this floor heating board 2, a pipe 4 made of a thermoplastic resin and covered with an aluminum foil 5 for distributing a heat medium is provided. It lays through between the projections 3 of. Then, the aluminum foil 6 is covered thereover, and a floor material (wood in the case shown) 7 is laid on the aluminum foil 6 to implement the present proposal.

[0009] Furthermore, there is provided a connecting portion 7a having a discontinuous shape between adjacent floor members 7, and nails 8 are provided from above the lower portion of both connecting portions 7a toward the floor base 1. The floor material 7 is sequentially fixed by driving. On the other hand, at least a part of the projections 31 of the projections 3 on the floor heating board 2 is formed on an uneven surface 32 whose peripheral surfaces are parallel to each other in the vertical direction as shown in FIG. It is preferable to determine the laying state of No. 3, 32a is its convex portion, and 32b is the concave portion.

That is, when the pipe having a relatively small diameter is laid, the convex portion 32 a supports the pipe 4, and when laying the pipe having a relatively large diameter, the convex portion 32 a is crushed and can support the pipe 4. The cushioning property is exerted at the time of laying, and the pipe 4 can be effectively supported by the uneven surface 32 even when the pipe diameters are slightly different. Further, it is more preferable that the protrusions 3 and the protrusions 31 are alternately arranged so that the arrangement of the protrusions 3 and the protrusions 31 is symmetrical in the front-rear direction and / or the left-right direction in order to stabilize the laid state of the pipe 4.

As the floor heating board 2, for example, a quadrangular polystyrene foam having a size of 600 mm × 840 mm × 25 (thickness) mm is used, and the center distance between the adjacent protrusions 3 and 31 is not limited. Is also 120 mm. One of the protrusions 3 has a cylindrical shape with a diameter of 50 mm, and the height is 7 mm. The protrusion 31 having the uneven surface 32 has a height of 7 mm and a convex portion 32a. Has a diameter of 55 mm, the recess 32b has a diameter of 50 mm, and the number of convex portions 32a is 12.

Next, as the pipe 4, for example, a pipe made of a low density polyethylene cross-linking body having an inner diameter of 5 mm and an outer diameter of 8 mm is used, and the aluminum foil 5 covering the pipe 4 has a thickness of, for example, Is an aluminum foil having a thickness of 10 to 80 μ (micron) as an intermediate layer, and a saturated polyester resin layer such as polyethylene terephthalate having a thickness of 1 to 100 μ on both sides thereof and an acrylic resin having a thickness of 0.1 to 100 μ. A laminated tape formed by laminating and bonding layers is used, and the laminated tape is wound in a spiral shape with the saturated polyester resin layer on the pipe 4 side. The thickness of the aluminum foil 6 provided on the lower surface of the floor material 7 is 10 to 300 μm.

[0013]

[Effect of the device]

 The present invention is as described above, and it goes without saying that by laying a floor heating board having a large number of protrusions, there is a degree of freedom in pipe size and pipe pitch, and a piping pattern can be arbitrarily selected. Since a pipe covered with aluminum foil was used and a heat conduction layer made of aluminum foil was provided between the floor heating board and the floor material on the surface side, heat conduction to the floor was extremely good. Floor heating can be performed uniformly.
