Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor heating panel that heats a room from the floor.

[0002]

[Prior art]

 In recent years, as a floor heating panel for heating the room from the floor surface, as shown in FIG. 3, a pipe housing groove 11 is formed on the upper surface of a substrate 10 made of a medium-quality fiberboard that is made by heat-pressing wood fibers together with a special adhesive. A floor heating panel has been developed, which is formed by engraving, arranging and storing the hot water pipe 12 in the pipe storing groove 11, and sticking and laminating a heat equalizing material 13 such as an aluminum sheet on the substrate 10. ing.

[0003]

[Problems to be solved by the device]

 Although the substrate made of the above-mentioned medium fiber board has excellent mechanical strength, when the warm water is circulated in the warm water pipe to heat the room, the heat is radiated from the warm water pipe so that the substrate 10 moves from the longitudinal center to both ends. There was a problem that it was curved in a semi-circular shape.

[0006] Therefore, even in the floor heating panel using the conventional urethane foam or wood board as the substrate, there is a problem that the substrate is warped due to heat radiation from the hot water pipe. As a means for solving such a problem, it is known from Japanese Utility Model Application Laid-Open No. 56-162492 that a plurality of slits are provided on a substrate made of urethane foam. However, the substrate made of urethane foam has low mechanical strength, and if a slit is provided that can reliably prevent the warp of the substrate, the slit will open outward when a load is applied to the substrate. However, the number of slits and the position where the slits are provided are restricted because there is a risk that they will bend back and break from the slits. Therefore, it was impossible to surely prevent the warp of the substrate by forming a required number of slits in parallel with the short side of the substrate at regular intervals.

Further, a means for preventing the warp of the board by providing a board made of a wooden board with a slit obliquely with respect to the longitudinal direction of the board or in the shape of a saw blade is known from Japanese Utility Model Laid-Open No. 4-82613. However, the board made of wood board also has low mechanical strength like the board made of foamed urethane described above, and in order to prevent this decrease in mechanical strength, a minimum slit is formed in the longitudinal direction of the board. It is necessary to provide it obliquely or in a saw-tooth shape, and there is also a restriction on the installation position. For this reason, it was impossible to surely prevent the warp of the substrate by forming a required number of slits along the short side of the substrate in parallel with the required number of slits.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a floor heating device that reliably prevents warpage of a substrate and is excellent in load bearing characteristics at low cost.

[0007]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the problems of the prior art, the present invention forms a required number of slits at regular intervals on the upper surface of a substrate made of a medium-quality fiberboard having a pipe accommodating groove, in parallel with the short side of the substrate. To form a floor heating panel.

[0008]

[Action]

 A warp of the substrate is prevented by forming a required number of slits on the upper surface of the substrate made of a medium-quality fiber board in parallel with the short side of the substrate at regular intervals. That is, the heat is radiated from the hot water pipe, so that the substrate is elongated in the longitudinal direction. By forming a required number of slits that can reliably absorb this extension in parallel with the short sides of the substrate at regular intervals, warpage due to the extension of the substrate in the longitudinal direction is reliably prevented. . In addition, since the substrate made of medium-quality fiberboard has excellent mechanical strength, even if the required number of slits that can surely prevent the warp of the substrate is formed at a constant interval in parallel with the short side of the substrate, It does not affect the loadability.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the present invention, and FIG. 2 is a perspective view showing a substrate constituting the present invention. In FIG. 1, reference numeral 1 denotes a wood fiber with a special adhesive, which is hot pressed and laminated. A substrate made of a medium-quality fiber board, 2 is a pipe accommodating groove formed in a predetermined pattern on the upper surface of the substrate 1, 3 is an upper surface of the substrate 1 having a pipe accommodating groove 2 formed therein, and a short side of the substrate 1 is formed. It is a slit that is drilled in the required number in parallel with the slit. The number of threads of the slits 3 provided on the substrate 1 at regular intervals, the groove width and the depth of the slits 3 can be appropriately changed depending on the length dimension of the substrate 1. Reference numeral 4 denotes a hot water pipe made of resin pipe or the like arranged and accommodated in a pipe accommodating groove 2 formed on the upper surface of the substrate 1, and 5 denotes soaking of an aluminum sheet or the like stuck and laminated on the upper surface of the substrate 1. It is a material.

In the floor heating panel of the present invention configured as described above, when hot water is circulated through the hot water pipe 4 arranged and housed in the pipe housing groove 2 formed in the upper surface of the substrate 1, the hot water is heated. The substrate 1 expands in the longitudinal direction due to heat radiation from the pipe 4, but slits 3 having a number of lines capable of absorbing this expansion are provided at a constant interval in parallel with the short side of the substrate 1. As a result, the warp due to the elongation of the substrate 1 in the longitudinal direction is surely prevented. Moreover, since the substrate 1 made of a medium-quality fiber board is excellent in mechanical strength, a required number of slits 3 capable of surely preventing the warp of the substrate 1 are formed in parallel with the short sides of the substrate 1 at regular intervals. Even if it is installed, it does not hinder the load resistance. Further, since the slit 3 can be simultaneously processed when the pipe storage groove 2 is formed by router processing or the like, the floor heating panel that reliably prevents the warp of the base plate 1 and is excellent in load bearing is inexpensive. can get.
