BACKGROUND OF THE INVENTION
The present invention relates to a floor heating structure in which a floor finish is laid on a floor heating heating member having a heating element.
[0002]
[Prior art]
In order to perform floor heating, the heating elements for floor heating laid under the floor finishing material include the joist installation type installed on the joist and the joist installation type installed between the joists. However, in the joisting type, the heating element such as an electric heater is provided only in the joisting part, so the temperature rise in the joisting part of the flooring material cannot be expected, and the temperature on the floor surface of the floor heating area There is a problem that unevenness occurs.
[0003]
In order to prevent the occurrence of temperature unevenness, which is a problem when using such a heating element for floor heating between floor joists, for example, a floor with floor joists disclosed in JP-A-4-257626 is disclosed. There is one in which a heat equalizing plate with good thermal conductivity is laminated on an electric heater as a heating element, such as a heating member for heating.
[0004]
As shown in FIG. 4 (a), the heat generating member for floor heating is formed by sequentially laminating a heat insulating layer 51, a lower soaking plate 52, an electric heater 53, an upper soaking plate 54, and a surface layer 55. Only the upper soaking plate 54 laminated on the electric heater 53 protrudes so as to cover the upper surface of one joist A as shown in FIG.
[0005]
When the heating member 50 for floor heating configured as described above is installed on the heat insulating member B installed in the portion between the joists A as shown in FIG. Since the portion covers the upper surface of the joist A, the heat of the electric heater 53 provided only in the joist A portion is transmitted to the floor finishing material 60 on the joist A through the upper heat equalizing plate 54. The temperature distribution of the floor finish 60 can be made uniform.
[0006]
[Problems to be solved by the invention]
However, in the state where the heating element 50 for floor heating of the joist installation type as described above is installed, not only the joisting part but also the upper part of the joist are covered with the heating element 50 for floor heating. When laying the floor finishing material 60 on the heat generating member 50, the installer cannot recognize the joist part that nails the floor finishing material, and the floor finishing material 60 can be efficiently laid. There is a problem that can not be.
[0007]
Accordingly, an object of the present invention is to provide a floor heating structure that can prevent the occurrence of uneven temperature on the floor surface in the floor heating region and can efficiently perform the floor finishing material laying operation.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is a floor heating installation member of a floor heating installation type having a plurality of joists arranged in parallel at regular intervals, a heating element, and the floor heating. A floor heating structure provided with a floor finish laid on a heating member for heating, wherein the heating member for floor heating is fitted between the joists and has a plurality of heating elements disposed on the upper surface the heat insulating members to each other, and a connecting member comprising a net connected to each other at their upper side, the floor covering is in contact surface with the floor heating generating member, having good thermal conductivity equalizing The present invention provides a floor heating structure in which a heat sheet is attached.
[0009]
In the floor heating structure configured as described above, the heat generating member for floor heating comes into contact with a part of the soaking sheet, so the heat of the heating member for floor heating is transmitted to the entire floor finishing material by the soaking sheet. Is done.
[0010]
In addition, in the state where the heating member for floor heating is installed, the entire floor heating area including the joists will be covered with the connecting member, but this connecting member is formed by the net and the soaking sheet is on the floor finishing material side. Since the floor finishing material is laid on the heating element for floor heating, the joist part can be clearly recognized from the installed heating element for floor heating. It is possible to efficiently perform the floor finishing material laying work that must be nailed to the floor.
[0011]
As the soaking sheet, it is desirable to use an aluminum foil having a thickness of 80 μm or more, and the thickness of the aluminum foil is desirably 150 μm or less. This is because if the thickness of the aluminum foil used as the soaking sheet is 80 μm or less, a sufficient soaking effect cannot be obtained, and if it is 150 μm or more, the cost increases.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 2, the floor heating structure 1 includes a plurality of joists A arranged in parallel at regular intervals so as to be orthogonal to an unillustrated large fork, and between these joists A (of the joists A). A heating element for floor heating (hereinafter referred to as a heating member) 20 of the joist installation type laid on the top) and a floor finishing material 10 laid on the heating member 20.
[0013]
As shown in FIG. 1, the floor finishing material 10 includes a base material 11 formed of a 3-ply plywood, a 5-ply plywood, or the like, and a surface decorative material 12 such as a veneer attached to the upper surface of the base material 11. The floor finish 10 is composed of a contact surface with the heat generating member 20, that is, a soaking sheet 13 with good thermal conductivity adhered to the back surface side of the base material 11. In the state where it is bonded to the upper surface of the heat generating member 20, it is nailed to the joist A portion.
[0014]
The soaking sheet 13 is formed of an aluminum foil having a thickness of 80 to 150 μm, and the fiber direction of the surface decorative material 12 made of a veneer and the fiber direction of the surface layer portion of the substrate 11 are orthogonal to each other. ing. The aluminum foil as the soaking sheet 13 can ensure a sufficient soaking effect if the thickness is 80 μm or more, and even if it is thicker than necessary, there is no difference in soaking effect. Considering the surface, it is desirable to set the thickness of the aluminum foil to 80 to 150 μm.
[0015]
As shown in FIG. 2, the heat generating member 20 includes a plurality of heat insulating members 21 made of foamed urethane blocks and the like arranged in parallel at regular intervals so as to be fitted between the joists A, and An electric heater 22 composed of a line heater disposed on the upper surface, and a connecting member 23 composed of a polyester resin net for interconnecting a plurality of heat insulating members 21 disposed with the electric heater 22, The connecting member 23 connects the plurality of heat insulating members 21 to each other by sticking the upper surface of each heat insulating member 21 to the back side thereof.

[0016]
In the floor heating structure 1 described above, first, a plurality of joists A are arranged in parallel at regular intervals so as to be orthogonal to an unillustrated large drawing, and then each heat insulating member 21 is fitted between the joists A. The heating member 20 is laid on the joist A, and the floor finishing material 10 is further laid thereon.
[0017]
As described above, the floor finish 10 is preliminarily pasted with the soaking sheet 13 made of aluminum foil on the contact surface with the heating element 20 of the joist installation type, and thus the electric heater 22 of the floor finish 10. Since the heat of the electric heater 22 is also transmitted through the soaking sheet 13 to the upper part of the joist not provided with, the occurrence of temperature unevenness on the floor surface in the floor heating area can be prevented.
[0018]
In the state where the heat generating member 20 is installed, the entire floor heating area including the joist A is covered with the connecting member 23. The connecting member 23 is formed of a polyester resin net and has a soaking sheet. 13 is attached in advance to the floor finishing material 10 side, and therefore when the floor finishing material 10 is laid on the heating member 20, the joist A portion is clearly recognized from above the installed heating member 20. Therefore, it is possible to efficiently perform the laying work of the floor covering 10 that must be nailed to the joist A portion.
[0019]
In addition, in this embodiment, although the heat generating member 20 which the electric heater 22 was arrange | positioned by the upper surface and connected the some heat insulation member 21 with the connection member 23 is used, it isolate | separated for every joist. Needless to say, the same effect can be obtained when a normal joist installation type heat generating member in which the heat generating members are respectively installed is used.

Even when the heating member 30 of the joist top installation type to which the reinforcing plate 33 is attached is used, it is adjacent by using the floor finishing material 10 having the soaking sheet 13 attached to the back surface as described above. Generation of temperature unevenness due to the absence of the electric heater 32 between the heat generating members 30 can be effectively prevented, and when the floor finish 10 is laid on the heat generating member 30, the heat generating member 30 installed is installed. Since the nailable area display etc. given to the upper surface of the floor can be clearly grasped, the flooring material 10 can be efficiently laid. In addition, in this floor heating structure 2, in order to prevent transmission of heat to the lower side, a heat insulating member B is installed between the joists A.
[0021]
Further, when the floor finishing material 10 having the soaking sheet 13 attached to the back surface as described above is laid out so as to protrude outward from the inside of the floor heating area where the heating members 20 and 30 are installed, There is also an advantage that it is possible to prevent an abrupt temperature drop of the floor surface at the boundary portion of the heating area (the portion where the heat generating members 20 and 30 are not installed).
[0022]
Moreover, in embodiment mentioned above, although aluminum foil is used as the soaking | uniform-heating sheet | seat 13 with favorable heat conductivity, it is not limited to this, For example, metal foil, such as copper foil and zinc foil, Thin metal plates such as aluminum plates and copper plates can also be used.
