Description

  The present invention relates to a floor heating panel that can be applied not only to newly installed floor heating but also to floor heating by renovation, and a method for constructing the same, by unitizing the floor heating panel.

  Electric floor heating, which has been implemented as an indoor heating system in the past, has a heater wire, such as nichrome wire, placed under the floor finishing material and heated to generate heat by energizing it. It is something to be made. However, the floor heating system using such a heater wire has a partial temperature unevenness on the floor surface, and when one of the heater wires is disconnected, the entire surface does not generate heat, or when an electric leakage occurs. In recent years, there is a risk of electric shock, and when renovating an existing building and adding new floor heating, the floor becomes taller by the thickness of the floor heating panel. Floor heating using heating elements is the mainstream.

As a conventional example of floor heating using this sheet heating element, a floor heating panel described in Patent Document 1 includes a plate-like body, a sheet heating element, a hard resin foam, and a soft resin foam from the surface side. Are sequentially laminated, and the sheet heating element has a configuration using, for example, a stainless hoop material on a resin film. Therefore, this planar heating element has a laminated structure sandwiched between a plate-like body and a hard resin foam, and has no flexibility in shape deformation when the planar heating element thermally expands. If the shrinkage due to cooling is repeated, for example, in the case of a carbon-based planar heating element, there is a drawback that the organic chemical substance kneaded in the resin film is deteriorated, a comfortable temperature cannot be obtained, and further no heat is generated. .

By making the total thickness of the wood and floor heating panel equal to the thickness of the existing flooring, the finished floor becomes a uniform floor with no irregularities, and it is possible to construct a floor structure suitable for barrier-free It becomes.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the floor heating panel 1 according to the present invention is unitized by setting the floor heating panel 1 including the heater wires 2 to have a predetermined planar shape and a predetermined thickness, and uses a conventional planar heating element. The floor heating panel structure of the cable system by the heater wire 2 is used.

  The dimensional relationship in the planar shape of the floor heating panel 1 of the present invention is as follows. When the planar shape of the floor heating panel 1 is a rectangle or a square, and the length is L and the width is W, L × W = 1700 mm × 900 mm, L × W = 1300mm × 900mm, L × W = 850mm × 900mm, L × W = 600mm × 600mm, L × W = 1700mm × 300mm, L × W = 1300mm × 300mm, L × W = 850mm × 300mm, etc. It is possible to produce several types of panel shapes with the set vertical length and horizontal width, and use a panel having an appropriate size according to the newly installed or existing installation area.

  FIG. 2 shows a specific example relating to the laying construction of the floor heating panel 1, a joist 22 is hung on the fork 21, a plywood 24 is attached to the upper part of the joist 22, and a heat insulating material 23 is provided. The floor heating panel 1 of the present embodiment is provided on the plywood 24, and the finishing material 4 such as flooring is laid on the upper surface thereof. In such construction, the finishing material 4 is laid on a uniform floor without unevenness by laying the height adjusting plywood 3 having the same thickness as the floor heating panel 1 around the floor heating panel 1. It becomes possible to be suitable for barrier-free.

  In addition, when describing a specific dimension regarding said construction, the thickness D1 of the height adjustment plywood 3 is made equal to the thickness D2 of the floor heating panel 1 = 5.5 mm, and is overlapped on the surface of the floor heating panel 1. By setting the thickness D3 of the finishing material 4 to 7 mm, the total of the thickness D2 of the floor heating panel 1 and the thickness D3 of the finishing material 4 becomes 12.5 mm.

  Hereinafter, the structure of the floor heating panel 1 of the present embodiment will be described. As shown in FIG. 2 or FIG. 3, the floor heating panel 1 has a heat transfer plate 5 made of a thin metal plate having high heat transfer properties disposed on the entire surface of the floor heating panel 1. As the heat transfer plate 5, an aluminum plate having a thickness of about 0.5 mm is used. By efficiently transferring the heat of the heater wire 2 attached to the back surface of the heat transfer plate 5, the entire heat transfer plate 5 is used. It is possible to raise the temperature evenly.

  In addition, an anti-magnetic performance of the aluminum plate constituting the heat transfer plate 5 constitutes an electromagnetic shield for preventing electromagnetic waves from the heater wire 2, and a waterproof sheet for preventing moisture from entering the heater wire 2 side from the floor. As an effect. Further, since the ground wire 6 is connected to the heat transfer plate 5 as will be described later, even if the heater wire 2 leaks electricity, the heat transfer plate 5 plays a role of grounding so as to cause an electric shock. It can be avoided.

  Moreover, the heater wire 2 is attached to the back surface of the heat transfer plate 5 with a predetermined interval. As shown in FIG. 3, the heater wire 2 includes a heating element 2c in which conductive carbon and an insulating crosslinkable polymer are mixed between two conductors 2a and 2b, and a fluororesin is formed on the entire periphery thereof. By applying the insulating coating 2d, a parallel electric circuit is formed over the entire length of the heater wire 2.

  With the above structure, when the heating element 2c is cooled, the conductive carbon bonds are dense and the resistance value is small and the current flows easily. However, as the heating element 2c rises in temperature, the crosslinkable polymer expands. Initially, the conductive carbon bond becomes coarse and the resistance value increases, so that it becomes difficult for current to flow, temperature rise is suppressed, and power consumption is also reduced. As described above, the heater wire 2 is a self-heating suppression heater formed by molding the heating element 2c in which conductive carbon and an insulating crosslinkable polymer are mixed between the two conductive wires 2a and 2b. By controlling the temperature of the heater wire 2 by itself, there is no need for conventional thermostats and temperature-sensitive fuses that are prone to failure, and there is no risk of disconnection or abnormal heating even if bent or stacked. It is possible to demonstrate safety and durability.

  Further, as shown in FIG. 2 or 3, a protective sheath 8 that accommodates the heater wire 2 is fixed to the back surface of the heat transfer plate 5 via an air layer 7. The protective sheath 8 is made of a galvanium steel plate, is formed in a long shape along the heater wire 2 attached to the back surface of the heat transfer plate 5, and is expanded and expanded to the heater wire 2 through the internal air layer 7. Since the degree of freedom of contraction is given, the durability and safety of the heater wire 2 can be maintained unlike the conventional planar heating element.

  Moreover, since the protective sheath 8 is formed of a galvanium steel plate, it is possible to seal an electromagnetic wave emitted from the heater wire 2 due to the magnetic shielding effect of the galvanium steel plate. In the present embodiment, as shown in FIG. 1, the heater wire 2 drawn from the protective sheath 8 is connected to the heater wire 2 drawn from the adjacent protective sheath 8 by the T-shaped mold 20. .

  Furthermore, in this embodiment, as shown in FIG. 3 or FIG. 4, the piece of wood 9 is fixed at a position on the back surface of the heat transfer plate 5 and avoiding the place where the heater wire 2 and the protective sheath 8 are installed. A heat insulating material layer 10 surrounding the protective sheath 8 and the piece of wood 9 is attached to the entire back surface of the heat transfer plate 5 with a predetermined thickness. Further, the ceramic powder 11 is applied to the surface of the heat transfer plate 5, and the fixing position of the piece of wood 9 is displayed on the surface of the ceramic powder 11 as a nailing portion 12. In such a configuration, the heat insulating material layer 10 is formed of a rigid foamed urethane foam, exhibits waterproofness by the rigid foamed urethane foam, and does not allow the heat transferred to the heat transfer plate 5 to escape downward. This increases the efficiency of transferring the heat of the plate 5 upward.

  Also, the back side paper 18 with aluminum vapor deposition on the inner side is attached to the back side of the heat insulating material layer 10 to keep the heat transferred to the hard foamed urethane foam inside and prevent the heat from escaping to the lower outside. can do.

  Further, the ceramic powder 11 applied to the surface of the heat transfer plate 5 has a characteristic of radiating far infrared rays, and its wavelength is 8 to 14 microns which is very easily absorbed by the human body. Heat conduction to the flooring and temperature rise in the room are performed quickly.

  Furthermore, as shown in FIG. 7, the fixed position of the piece of wood 9 is displayed on the surface of the ceramic powder 11 as a nailing portion 12. This is because the surface of the brown ceramic powder 11 is colored in an easily distinguishable manner such as green in accordance with the position of the piece of wood 9 and is displayed with characters such as “nailing” or the like. It is possible to easily discriminate a portion provided with a portion that can be nailed.

  Further, in the floor heating panel 1 of the present embodiment, as shown in FIG. 1, connection boxes 15 are embedded at the corners on both sides in the planar region of the floor heating panel 1, and the heaters in the protective sheath 8 are embedded in the connection box 15. The configuration is such that the line 2 is derived.

  As shown in FIG. 5, the connection box 15 is embedded in an incision groove 13 in which a predetermined portion of the heat transfer plate 5 is rectangularly cut, and a rectangular lid portion 14 that closes the upper opening of the connection box 15 is provided. The two projecting pieces 14a and 14a provided on the side of the lid 14 are hooked and closed in the holes 15a and 15a on the side of the connection box 15, and further on both sides of the convex rectangular portion 14b of the lid 14 By pushing down the formed downward pieces 14c, 14c to the opening 17, the lid 14 can be fixed as shown in FIG.

  As shown in FIG. 6 (a), an insertion portion 16 is formed on the side portion of the rectangular portion 14b of the lid portion 14. By inserting the tip of a minus driver into the insertion portion 16, the lid portion 14 is removed. It can be easily removed.

  Further, as shown in FIG. 6B, by arranging the floor heating panels 1 and 1 side by side, the openings 17 and 17 of the respective line boxes 15 and 15 are opposed to each other, and are protected in the respective connection boxes 15 and 15. The conductors 2a and 2b of the heater wire 2 led out from the inside of the sheath 8 (see FIG. 1) are connected to the adjacent conductors 2a and 2b by the connector 19 and connected to the connection terminals 6a and 6a of the heat transfer plates 5 and 5, respectively. Connected ground wires 6 and 6 are connected by a connector 19.

  In addition, when the upper part of each connection box 15 is closed with the lid part 14, it is possible to prevent the deformation when the lid part 14 is pressed inward by supporting the lid part 14 with the thickness of the connector 19. Become.
