Description

  The present invention relates to a floor heating panel that can improve heating performance and maintain floor strength.

  As shown to Fig.5 (a), the floor heating panel 1 used for an electric floor heating is longitudinal length L (for example, 1818 mm ... 6 scale), width W (for example, 303 mm ... 1 scale), and thickness T (for example, 12 mm). Are standardized, and as shown in FIG. 5 (b), they are spread vertically and horizontally on the upper surface of the floor base (see Patent Document 1).

  As the floor heating panel 1 as described above, the first background art of FIG. 6 (a), which is a cross-sectional view taken along the line BB of FIG. 5 (a), forms a dug portion 2a on the back surface of the wooden flooring 2. Then, the sheet heating element 3 is adhered to the bottom surface of the dug portion 2a, and the sheet material (plywood, foamed resin, etc.) 4 is adhered to the back surface of the sheet heating element 3. . Reference numerals 2c and 2d are male and female fruits for spreading the floor heating panel 1 in a fitted state.

  If the thickness T of the wooden flooring 2 is 12 mm, the dug portion 2a is dug from the back surface of the wooden flooring 2 at a depth t1 of 3 mm, and the bottom of the dug portion 2a is 1 mm thick. While the planar heating element 3 of t2 is stuck, the planar material 4 of 2 mm thickness t3 is stuck to the back surface of the planar heating element 3.

  In the second background art of FIG. 6B, a dug portion 2a is dug at a depth t1 of 6 mm from the back surface of the wooden flooring 2, and a 1 mm thickness t2 surface shape is formed on the bottom surface of the dug portion 2a. While sticking the heat generating body 3, the vacuum heat insulating material 8 of 5 mm thickness t3 is arrange | positioned at the back surface of the planar heat generating body 3, and the sheet material (paper, about 0.2 mm in thickness, for example on the back surface of the wooden flooring 2 is provided. By adhering 9 (resin, metal, etc.), the digging portion 2 a is closed.

  In the background art 1, since the thickness t6 of the wooden flooring 2 positioned on the planar heating element 3 is 9 mm, there is a problem that the temperature raising speed is slow and the vertical heat dissipation efficiency is also poor.

On the other hand, in the background art 2, in addition to the thickness t6 of the wooden flooring 2 positioned on the planar heating element 3 being 6 mm, the vacuum heat insulating material 8 is arranged to arrange the wooden flooring 2. Since heat radiation toward the back side can be remarkably suppressed, the temperature raising speed is increased and the vertical heat radiation efficiency is improved.

  However, in Background Art 2, if a hole is accidentally opened in the vacuum heat insulating material with a nail or the like during construction of the floor heating panel, the heat insulating performance is not exhibited, and the wooden floor material 2 located on the planar heating element 3 is not provided. Since the thickness t6 is 6 mm, there is a problem in strength such as easy bending when the floor is stepped on.

  The present invention has been made to solve the above problems, and by using a vacuum heat insulating material, the temperature raising speed is increased and the vertical heat dissipation efficiency is improved, thereby improving the heating performance and saving energy. To provide a floor heating panel that is excellent in that it is possible to minimize the influence of a hole in the vacuum insulation material when it is accidentally opened during construction of the floor heating panel, and to maintain sufficient floor strength. It is intended.

  In order to solve the above problems, the present invention provides a floor heating panel in which a sheet heating element is attached to the bottom surface of a dug formed on the back surface of a wooden floor material. The present invention provides a floor heating panel in which a plurality of vacuum heat insulating materials are arranged side by side, and a crosspiece is disposed between the vacuum heat insulating materials.

  In order to keep the vacuum heat insulating material from falling off, a convex portion is formed on the lower surface of the crosspiece, and an end portion of the vacuum heat insulating material is inserted between the convex portion and the planar heating element. It is preferable to do.

  In order to keep the vacuum heat insulating material from falling off, it is preferable to form a recess in the side surface of the crosspiece and insert the end of the vacuum heat insulating material into the recess.

  According to the present invention, on the basis of the configuration of the background art 2, a plurality of vacuum heat insulating materials are arranged side by side on the back surface of the planar heating element, and a crosspiece is arranged between the vacuum heat insulating materials. Similar to the background art 2, the thickness of the wooden floor located on the planar heating element is thinner than the background art 1 (for example, the thickness t6 is 6 mm), so the temperature raising speed is increased (comfort). The heat dissipation efficiency is improved (energy saving), and the heating performance is improved.

  In addition, since a plurality of vacuum heat insulating materials are arranged side by side, heat radiation toward the back side of the planar heating element can be remarkably suppressed, so that the heating performance is further improved, and the floor substrate and the floor heating panel It becomes possible to omit the heat insulating material interposed between the two. Furthermore, even if the floor heating panel is accidentally opened with holes such as nails in some of the vacuum insulation materials and the insulation performance may not be demonstrated, the effect will affect the entire floor heating panel. It can be avoided in advance.

  Furthermore, since a crosspiece as a reinforcing member is disposed between the vacuum heat insulating materials, it becomes difficult to bend when the floor is stepped on, and the strength of the floor can be sufficiently maintained.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Note that portions having the same configuration and operation as those of the background art are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 1A is a cross-sectional view of the floor heating panel 6 corresponding to the AA line cross section of FIG. 5A, and FIG. 1B is a bottom (back) view of the floor heating panel 6.

  As shown in FIG. 2, a dug portion 2 a is formed on the back surface of the wooden flooring 2, and the planar heating element 3 is adhered to the bottom surface of the dug portion 2 a. This sticking can be performed with, for example, a hot melt adhesive. Reference numerals 2e and 2f are recesses for the connector of the terminal of the lead wire for connecting the floor heating panel.

  If the thickness T of the wooden flooring 2 is 12 mm, the dug portion 2a is dug at a depth t1 of 6 mm from the back surface of the wooden flooring 2 as in the background art 2 of FIG. Then, the sheet heating element 3 having a thickness of 1 mm t2 is adhered to the bottom surface of the dug portion 2a, and a plurality of (6 sheets in this example) vacuum insulation of 5 mm thickness t3 is attached to the back surface of the sheet heating element 3. The materials 8 are arranged side by side in the length direction. The vacuum heat insulating material 8 is obtained by packaging a core material with a packaging material having a gas barrier property.

  Further, by sticking a sheet material (paper, resin, metal, etc.) 9 having a thickness of about 0.2 mm, for example, to the back surface of the wooden floor material 2, the dug portion 2a is closed. A plurality of (five in this example) horizontal crosspieces 10 are arranged between the vacuum heat insulating materials 8.

  In the case of the floor heating panel 6 as described above, based on the configuration of the background art 2, a plurality of vacuum heat insulating materials 8 are arranged side by side on the back surface of the planar heating element 3, and the space between the vacuum heat insulating materials 8 is determined. By disposing the crosspiece 10 in the same manner as in the background art 2, the thickness of the wooden flooring 2 positioned on the planar heating element 3 is thinner than that in the background art 1 (for example, the thickness t6 is 6 mm). Therefore, the heating speed is improved (comfort) and the heat dissipation efficiency is improved (energy saving), so that the heating performance is improved.

  Further, since the plurality of vacuum heat insulating materials 8 are arranged side by side, the heat radiation toward the back surface of the planar heating element 3 can be remarkably suppressed, so that the heating performance is further improved and the floor base and the floor heating are further improved. It is possible to omit a heat insulating material interposed between the panel 6 and the panel 6.

  Furthermore, even when the floor heating panel 6 is constructed by mistake, nails or the like may cause a hole in a part of the plurality of vacuum heat insulating materials 8 and the heat insulation performance may not be exhibited. It can be avoided in advance.

  Furthermore, since the crosspieces 10 as the reinforcing members are disposed between the vacuum heat insulating materials 8, the floor is less likely to bend when the floor is stepped on, so that the strength of the floor can be sufficiently maintained.

  As shown in FIG. 3A, an inverted T-shaped convex portion 10 a is formed on the lower surface of the horizontal crosspiece 10, and the vacuum heat insulating material 8 is provided between the convex portion 10 a and the planar heating element 3. Since the vacuum heat insulating material 8 can be held so as not to drop off by inserting the end portion of the metal sheet, assembling becomes easy and productivity is improved, and a sheet material 9 is attached to the back surface of the wooden flooring 2. In the case where the dug portion 2a is closed, the sheet material 9 can be adhered to the convex portion 10a of the horizontal rail member 10, so that the shape stability of the sheet material 9 is also improved.

  As shown in FIG. 3 (b), a slit-like recess 10b is formed on the side surface of the horizontal beam member 10, and the end of the vacuum heat insulating material 8 (the core packaging material is intermediate in the thickness direction) in the recess 10b. By inserting a fin-like hard heat-welding end portion generated by heat-welding at the portion, the vacuum heat insulating material 8 can be held so as not to drop off, so that assembling becomes easy and productivity is improved. Since the width of the crosspiece 10 is increased, the strength of the floor is increased, and in addition, when the sheet material 9 is adhered to the back surface of the wooden floor material 2 to close the dug portion 2a, the sheet material 9 is Since the sheet can be attached to the wide crosspiece 10 having a wide width, the shape stability of the sheet material 9 is also improved.

  In the embodiment, six vacuum heat insulating materials 8 are arranged side by side in the length direction on the back surface of the planar heating element 3, and five horizontal beam members 10 are arranged between the vacuum heat insulating materials 8. However, as shown in FIGS. 4 (a) and 4 (b), two vacuum heat insulating materials 8 are arranged side by side in the width direction on the back surface of the planar heating element 3, and Alternatively, a single vertical crosspiece 11 may be disposed. Further, as shown in FIGS. 4C and 4D, twelve vacuum heat insulating materials 8 are arranged side by side in the length direction and the width direction on the back surface of the planar heating element 3, and each of the vacuum heat insulating materials 8 is arranged. One vertical crosspiece 11 and ten horizontal crosspieces 10 may be disposed between them.
