Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor heating panel structure disposed between large pulling members of an underfloor material.
[0002]
[Prior art]
A floor panel provided with a flat plate member on which a floor material is laid on the upper surface side and a plurality of joist members arranged side by side on the lower surface of the flat plate member has been conventionally used. It was arranged on the under-floor beam member called “member” and only served as a floor base material in which a flooring material or the like was pasted thereon.
Moreover, as a floor heating device for general homes, an underfloor beam member referred to as a “beam member” is assembled to the large drawing member so as to be orthogonal to the large drawing member. There was a type that incorporated multiple heat storage units that were unitized with heat storage materials and heat insulation materials.
In this case, in order to hold the heat storage unit, an L-shaped fastener or the like is attached to the side face of each joist member to hold the heat storage unit. Moreover, the electrical wiring work of the heat storage units employs a method in which adjacent heat storage units are electrically connected by a joint connector, and a plurality of heat storage units are arranged with a joist member and a large pulling member sandwiched therebetween. For this reason, the wiring cable is straddled across the joist member or the like (the lower surface is extended so as to extend over).
[0003]
[Problems to be solved by the invention]
The conventional floor heating device must take into account the space for fasteners and cable connections during construction, and the assembly is performed by fitting one heat storage unit between the joist members, attaching the fasteners, and Wiring work was very labor intensive and costly. Furthermore, since the heat storage unit has a certain weight, a number of fasteners corresponding to the heat storage unit is necessary, and the workability thereof is particularly problematic.
Further, since the cable straddles the joist member and the like, the cable hangs down, which is not preferable in appearance although it is under the floor, and there is a possibility that it may be caught with other members.
In addition, heat from the heat storage unit is transmitted through the joist member and radiated from the lower surface of the joist member, which has been a factor of lowering the thermal efficiency on the floor.
[0004]
Therefore, an object of the present invention is to provide a floor heating panel structure that can improve thermal efficiency on the floor, can be easily constructed, and can reduce the number of work steps.
[0005]

In order to achieve the above-described object, a floor heating panel structure according to the present invention includes a flat plate member on which a floor material is laid on the upper surface side, and a plurality of joist members arranged in parallel with the lower surface of the flat plate member. And a heat storage unit that is disposed between the joist members and includes a sheet heating element, a heat storage material, and a heat insulating material, and a heat insulating panel material that is attached to contact the lower surface of the joist member and the lower surface of the heat storage unit; In addition, the heat storage unit is composed of an upper surface heating element attached to the lower surface of the flat plate member, an intermediate heat storage material, and a lower heat insulating material, and the heat insulating panel.

The flat plate member 1 is made of a rectangular or square plywood, and the joist member 2 is made of square material generally used as an underfloor material. The flat plate member 1 has a length equal to one side of the flat plate member 1 and an end side of the flat plate member 1. A plurality (three in the present invention) are provided at equal intervals from the section.
In the example of the present invention, in the plurality of joist members 2 of the floor heating panel structure P, one of the joist members 2 and 2 on both sides is omitted (the virtual joist member 2 as shown in FIG. 7). ').
[0010]
Specifically, as shown in FIGS. 1 and 7, the rightmost joist member is omitted, but this is because the floor heating panel structure P is shown in FIGS. 2 and 7. Since it is continuously arranged, the joist member 2 'at the left end of the floor heating panel structure P' disposed next (right side) is incorporated into the omitted portion of the floor heating panel structure P (left side). Will be. That is, the joist member 2 ′ of the right floor heating panel structure P ′ is used as the virtual joist member 2 ′ of the left floor heating panel structure P, and the floor heating panel structure P is configured. Thereby, it is not necessary to increase the number of joist members 2 unnecessarily.
[0011]
Further, one end portion (side) of the flat plate member 1 is disposed along a substantially central line in the longitudinal direction of the upper surface of the joist member 2, and the other end portion (side) on the opposite side of the flat plate member 1 is an imaginary joist. It is comprised so that it may be arrange | positioned along the longitudinal direction approximate centerline of the upper surface of member 2 '. That is, the both side connecting portions of the floor heating panel structure P are in an offset state, and it is easy to install the floor heating panel structure P disposed next to the floor heating panel structure P, and the adjacent floor heating panel structure P , P does not have a gap.
[0012]
Next, the heat storage unit 3 will be described in detail. The heat storage unit 3 includes a side surface of the joist member 2 and a side surface (at least a side surface of the heat insulating material 12 of the heat storage unit 3) between the plurality of joist members 2 arranged in parallel. The lower surface 3b of the heat storage unit 3 and the lower surface 2b of the joist member 2 are configured so as to be parallel and substantially flush with the flat plate member 1.
In the present embodiment, in the heat storage unit 3, the planar heating element 10 is attached to the lower surface 1 b of the flat plate member 1, and the plate-like heat storage material 11 is attached to the lower surface of the planar heating element 10. A heat insulating material 12 is laid on the lower surface of the heat insulating material 12, and the heat insulating material 12 is in a state in which the planar heating element 10 and the heat storage material 11 are completely covered between the joist members 2 and 2 in a bottom view.
[0013]
The heat storage material 11 will be described. As shown in FIG. 2, the heat storage material 11 faces the lower surface b of the flat plate member 1 and has a shape slightly smaller than the dimension between the side surfaces of the joist member 2. It is a shape corresponding to the recessed part formed by the side surface.
The planar heating element 10 will be described. The planar heating element 10 is a heater that generates heat when energized, and its shape corresponds to the heat storage material 11, and although not shown, a cable (lead wire) is connected thereto.
The plate-like heat insulating material 12 is configured to cover the concave portion.
[0014]
Although not shown, a sheet material may be interposed on the lower surface 1 b of the flat plate member 1. This sheet material is for controlling the heat conduction between the flat plate member 1 and the planar heating element 10, and is made of a metal sheet having a high thermal conductivity such as aluminum. Thereby, the heat from the planar heating element 10 can be evenly transmitted to the flat plate member 1 without unevenness.
[0015]
Next, the heat insulation panel material 4 will be described. The heat insulating panel material 4 is disposed in parallel with the flat plate member 1 and, as described above, has a height (thickness) attached to the lower surface 3b of the heat storage unit 3 and the lower surface 2b of the joist member 2 so as to come into contact with the surface. It is a small cuboid. The height dimension of the heat insulating panel material 4 is set lower than the height dimension of the large pulling member 6 as shown in FIG. The width dimension D is set to be equal to or slightly smaller than the dimension W between the large pulling members 6 and 6 on which the joist members 2. That is, the heat insulating panel material 4 is disposed so as to be close to the side surface of the large pulling member 6. Further, as shown in FIG. 2, the length dimension of the heat insulating panel material 4 (the dimension of the remaining one side) is substantially the same as the dimension of the floor heating panel structure P, and the arrangement of the joist members 2 and the heat storage units 3. It corresponds to the installation length.
[0016]
Therefore, as shown in the bottom view of FIG. 3, the heat insulating panel material 4 causes the lower surface 3b of the heat storage units 3 ... and the lower surface 2b of the joist member 2 ... to work together with the large drawing members 6, 6 indicated by the two-dot chain line. , (Completely) closed. Thereby, while the heat insulation panel material 4 prevents the thermal radiation to the lower surface side by the heat storage unit 3 ..., the heat of the heat storage unit 3 ... is transmitted to the joist member 2 of the side, from the lower surface 2b of the joist member 2. Heat dissipation can be prevented. That is, the heat insulation performance can be further exhibited and the thermal efficiency on the floor can be improved.
[0017]
Further, since the heat storage unit 3 (particularly the heat storage material 11) is somewhat heavy, conventionally, the heat storage unit 3 is fixed to the joist member 2 or the like with a number of dedicated metal fittings or the like. Therefore, a plurality of heat storage units 3... Can be easily held (attached) at a time to form an integrated object (panel structure).
[0018]
Furthermore, the heat insulation panel material 4 forms the groove part 5 for cable wiring. The groove portion 5 is disposed in a direction perpendicular to the longitudinal direction of the joist member 2, and in FIG. 4, the groove portion 5 is formed as a concave groove substantially at the center of the upper surface 4 a of the heat insulating panel material 4. The groove 5 is a passage (wiring space) in which a cable from the sheet heating element 10 (heat storage unit 3) is disposed. As shown in the perspective view of FIG. The heat storage unit 3 passes through the groove 5 and is drawn out from the side opening of the groove 5 and is connected to the cable 7 of the adjacent floor heating panel structure P by a connector. That is, since the cable 7 is wired inside the floor heating panel structure P, the cable 7 does not get in the way during construction.
[0019]
FIG. 5 shows another embodiment, in which the groove 5 is disposed at the end of the upper surface 4 a of the heat insulating panel material 4, and the cable 7 is wired adjacent to the large pulling member 6. The heat insulating panel material 4 may be manufactured such that corners are cut out from a rectangular parallelepiped, or may be divided into two blocks at the joining line a as shown in FIG. In this case, it is only possible to bond two large and small rectangular parallelepipeds, the manufacturing is simple, and the cost can be reduced.
[0020]
Furthermore, another embodiment is shown in FIG. In this case, the groove portion 5 is provided with a concave groove similar to that shown in FIG. 4 on the lower surface 4b of the heat insulating panel material 4, and the cable 7 is passed through and covered with a lid member. In the case of this heat insulating panel material 4, the wiring of the cable 7 at the construction site and the modification of the wiring path are further facilitated.
A plurality of the groove portions 5 may be provided, and the cross-sectional shape of the groove portions 5 is not limited to a quadrangle, and may be other shapes. Further, although not shown in the drawings, the groove portion 5 is provided with a through hole in the thickness direction, and the cable 7 can be protruded and wired to the lower surface side of the floor heating panel structure P as necessary.
[0021]
The material of the heat insulating material 12 and the heat insulating panel material 4 is foamed plastic or the like made of urethane or styrene, has excellent moldability and excellent heat insulating effect, and the heat insulating panel material 4 is deformed to some extent during construction. Since it is free, it is easy to arrange in close contact between the large pull members 6 and 6. Thereby, it becomes possible to further prevent heat radiation from the joist member 2 and the heat storage unit 3.
[0022]
Further, in the present invention, the joist member 2 and the heat storage unit 3 are each three, and the weight of the floor heating panel structure P is reduced, so that the workability at the construction site is improved.
Furthermore, since the cable 7 is accommodated in the heat insulation panel material 4 and the heat insulation panel material 4 is a rectangular parallelepiped, the floor heating panel structures P can be overlapped with each other. Saves storage space.
[0023]
【The invention's effect】
The present invention has the following effects by the above-described configuration.
[0024]
The function as the floor base material and the function as the heat storage type floor heating can be exhibited while having a simple structure and being compact.
In addition, since the floor heating panel structure P is an integral body, the floor heating work is simply performed by placing the floor heating panel structure P one after another on the large pulling member 6, which has been necessary from the past. It is possible to incorporate the floor heating equipment by the same level of work as the construction of the floor material.
Furthermore, the heat storage unit 3 having a heavy weight is securely held. Moreover, the heat radiation from the lower surface 3b of the heat storage unit 3 and the lower surface 2b of the joist member 2 can be prevented, and the thermal efficiency on the floor can be improved.
[0025]
Electrical wiring work becomes easy at the construction site, and the number of work steps can be reduced. The drooping of the cable 7 can be prevented. Furthermore, the cable 7 is not exposed, the floor heating panel structure P can be stacked, and the transportation and handling are facilitated.
[0026]
Heat dissipation from the lower surface 2b of the joist member 2 can be prevented, and the thermal efficiency on the floor can be further improved.
