JP 2000-320843 A

  In an electric floor heating floor constructed by laying a large number of electric floor heating panels 10 of the form shown in FIG. 8 and FIG. It is possible to effectively avoid generation of abnormal noise due to contact between the upper surface of the connector and the panel base material or contact between the lower surface of the connector and the floor base. The present inventor has carried out a lot of construction of the electric floor heating floor by the electric floor heating panel 10 of the above form, but although it should be able to avoid the occurrence of abnormal noise, depending on the situation of the construction, I have experienced that floor noise can occur when walking on the floor.

  When many experiments were conducted to find out the cause, depending on the condition of construction, adjacent electric floor heating panels 10 are slightly in the longitudinal direction from a predetermined position (that is, a position where the connector housing recesses face each other). It has been found that after the connectors are connected to each other, the side surfaces of one or both connectors are in contact with the side wall of the connector housing recess. In that state, when a load from above was applied due to walking, irregular contact was repeated between the side of the connector and the side wall of the connector housing recess, and it was found that this was the cause of abnormal noise (flooring sound). .

  Even if irregular contact comes to occur between the connector side surface and the side wall of the connector housing recess for the convenience of construction, the present invention effectively generates abnormal noise (flooring sound) due to the contact. An object of the present invention is to provide an electric floor heating panel that can be prevented.

  An electric floor heating panel according to the present invention includes a panel base material formed of a wood material, an electric heater disposed on a back surface side of the panel base material, and a connector receiving recess formed on the back surface side of the panel base material. An electrical floor heating panel comprising at least a connector housed in the connector housing recess, the connector housing recess between the side wall of the connector housing recess and the side surface of the connector housed in the connector housing recess The present invention is characterized in that a buffer layer or a friction buffer layer is provided to prevent abnormal noise from being generated due to contact between the side wall of the connector and the side surface of the connector.

  In the electric floor heating panel described above, a slight positional shift occurs in the longitudinal direction between the adjacent electric floor heating panels during construction. Even if the position shifts laterally (in the longitudinal direction of the panel) from where it should originally be, noise is generated between the side wall of the connector housing recess and the side surface of the connector housed therein. A buffer layer or a friction buffer layer for preventing the occurrence is provided, and the side surface of the connector can be prevented from coming into direct contact with the side wall of the connector housing recess formed in the panel base material made of wood. Therefore, it is possible to effectively prevent the occurrence of abnormal noise (flooring noise) due to contact between the connector side face and the side wall of the connector housing recess, which is a wooden material, which may occur in the past.

  The buffer layer or the friction buffer layer for preventing the generation of the abnormal noise may be integrally formed on the side wall side of the connector receiving recess (Claim 2), and is formed integrally on the side surface side of the connector. (Claim 3). In some cases, it may be formed on both the side wall of the connector housing recess and the side surface of the connector.

  The method of providing a buffer layer or friction buffer layer for preventing the generation of abnormal noise is basically arbitrary. In the case of a buffer layer, an appropriate buffer material is provided on the side wall of the connector housing recess or the side surface of the connector. You may make it stick, and when connecting connectors in a construction site, it is good also by inserting a shock absorbing material between the side wall of a connector accommodation recessed part, and the side surface of a connector. The material for forming the buffer layer may be a material having a buffer property and a low frictional sound, and a nonwoven fabric, foamed resin, felt, or the like is preferably used. Among these, a nonwoven fabric is preferable.

  When the friction buffer layer is formed, a resin having friction buffering properties is preferably applied to the side wall of the connector housing recess. Part of the applied resin penetrates into the panel base material, which is a wood material, and a stable friction buffer layer is formed on the side wall of the connector housing recess. A resin having friction buffering properties may be applied to the side surface of the connector. Examples of the resin having frictional buffering properties include silicone oil, paraffin wax, and other known resins having frictional buffering properties. They may be liquid or solid. However, since it is used for a floor heating panel, a resin having a heat resistant temperature of 40 ° C. to 50 ° C. or higher is desirable.

  In the electric floor heating panel according to the present invention, in addition to the side surface of the connector housing recess and the side surface of the connector, the connector housing recess is also provided between the top surface of the connector housing recess and the upper surface of the connector housed in the connector housing recess. A buffer layer or a friction buffer layer may be provided to prevent abnormal noise from being generated due to contact between the top surface of the connector and the upper surface of the connector. Thereby, it is possible to prevent abnormal noise (flooring sound) from occurring due to contact between the top surface of the connector housing recess and the upper surface of the connector.

  In the case of the above form, the buffer layer or friction buffer layer provided on the top surface of the connector housing recess or the upper surface of the connector may be made of the same material as the buffer layer or friction buffer layer formed on the side wall of the connector housing recess or the side surface of the connector. Different materials may be used. In addition, the buffer layer or the friction buffer layer formed on the top surface and the side wall of the connector housing recess may be continuous or separated. Similarly, the buffer layer or the friction buffer layer formed on the upper surface and the side surface of the connector may be continuous or separated. Furthermore, the buffer layer may be formed on any surface, and the friction buffer layer may be formed on any other surface.

  In the electric floor heating panel according to the present invention, preferably, a cushioning material such as a nonwoven fabric sheet, a foamed resin sheet, or a laminated sheet thereof is attached to the back surface of the panel base material. Thereby, an electric floor heating panel suitable for being directly attached to the floor base is obtained. However, depending on the situation of the floor base, such a cushioning material can be omitted.

  By using the electric floor heating panel according to the present invention, it is possible to reliably prevent the generation of abnormal noise (flooring sound) when walking on the electric floor heating floor.

  That is, at the time of floor heating construction, the connector 4 and the other connector 3 of the adjacent electric floor heating panel 10A are connected. For convenience of construction, the connector 4 or Even when the connector after connection is positioned at the position where the side surface of the connector 4 comes into contact, the non-woven fabrics 20 and 20 functioning as a buffer layer are positioned on the side wall of the connector receiving recess 6. The side surface of the connector can be prevented from coming into direct contact with the side wall of the recess 6, and as a result, abnormal noise (floor generated by direct contact between the side wall of the connector housing recess 6, which is a wood material, and the side surface of the connector 4. Can be prevented from occurring.

  The electric floor heating panel 10B shown in FIG. 2 is different from the electric floor heating panel 10A shown in FIG. 1 in that a nonwoven fabric 21 is also attached to the top surface of the connector housing recess 6. In the illustrated example, the nonwoven fabric 21 on the top surface is continuous with the nonwoven fabrics 20 and 20 attached to the left and right side walls, but may be discontinuous. By sticking the non-woven fabric 21 to the top surface in this way, it is possible to reliably prevent the top surface of the connector from abutting against the top surface of the connector housing recess 6 to generate an abnormal sound (flooring sound). .

  The electric floor heating panel 10C shown in FIG. 3 relates to the other connector housing recess 5 formed on the side where the female fruit 12 is formed, and the other connector 3 is fixedly fixed in the connector housing recess 5.
