Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor heating structure and a construction method thereof, and more particularly, to an electrical floor heating structure and a construction method thereof that enable a work-saving workability in an electrical floor heating using an electric heater as a heat source.
[0002]
[Prior art]
An electric floor heating structure using an electric heater as a heat source is known, and its construction method is roughly divided into an integral construction and a separate construction. Integrated construction is a method of placing a large number of heating floor materials, in which a heat source such as a heater is attached to the back of the wooden decorative floor material in advance, and fixing it on the floor base with nailing, etc. The back surface of the floor material is a flat surface, and is arranged directly on the floor base surface or via a soaking plate such as a buffer sheet or aluminum foil.
[0003]
In remote construction, a heating panel that incorporates a heat source such as a heater in a required frame is fixed to a joist or floor foundation by nailing, etc. This is a method of arranging flooring by appropriate means. In this case as well, the front and back surfaces of the heating panel incorporating the heat source are flat surfaces, and if necessary, a soaking plate is provided. A wood-type decorative flooring material is disposed through (see Japanese Patent Application Laid-Open No. 11-21111, etc.).
[0004]
[Problems to be solved by the invention]
The integrated construction has an advantage that the construction is simplified as compared with the separate construction. However, when the surface of the wooden decorative flooring is scratched and reformed, it is necessary to replace the entire heating flooring incorporating the heat source body, which tends to increase costs. Furthermore, at the time of renovation, the heating floor material fixed to the ground surface by nailing or the like is peeled off at a necessary location, and the electrical connection is again secured to the new heating floor material to return it to the original state. Is not easy.
[0005]
In the separate construction, when the surface of the wooden decorative flooring is damaged, it is only necessary to replace the wooden decorative flooring, and remodeling can be performed at a relatively low cost. However, it is difficult to say that the overall construction cost is reduced considering the cost of manufacturing the heating panel incorporating the heat source and the labor for installing the heating panel and the wooden decorative floor separately.
[0006]
Also, in any construction mode, it is assumed that the ground surface is flat during construction, and at the time of renovation, the existing floor floor material is peeled off, and then the floor heating construction is performed as it is. Alternatively, it is extremely difficult to perform floor heating construction on an existing wooden decorative flooring.
[0007]
The present invention has been made in view of the circumstances as described above, and when it is newly constructed, and when it is constructed at the time of renovation, the construction can be reduced in comparison with the conventional one. An object of the present invention is to provide an electric floor heating structure capable of reducing the cost and a construction method thereof.
[0008]
[Means for Solving the Problems]
In the electric floor heating structure according to the present invention for solving the above-mentioned problem, basically, a lower cushion sheet for absorbing irregularities present on the ground surface is laminated on a ground surface having irregularities on the surface. In addition, on the upper surface of the lower cushion sheet, a heat source device composed of a heater, required wiring, and a connection connector is arranged and connected to a connection connector , on which a heater for the heat source device , required wiring, The upper cushion sheet having a thickness capable of absorbing the unevenness caused by the connected connector for connection is laminated, and the surface decorative material is laminated thereon without using an adhesive or a fixture. To do. The present invention also discloses a construction method for constructing the electric floor heating structure.
[0009]
In the electric floor heating structure and the construction method thereof according to the present invention, the foundation is arbitrary, and may be a floor foundation in a conventional flooring construction, for example, a concrete floor surface, directly or via a joist. It may be a discarded base plywood to be attached. Further, the base may be an existing floor surface decorative material, for example, a wooden decorative floor material on a wooden floor, a cushion material on a cushion floor laid with carpet, a resin sheet, a tile, and the like. When a new electric floor heating is to be introduced at the time of renovation, a structure using the existing floor surface decorative material as a base is suitable.
[0010]
Heat source equipment consisting of a heater and the required wiring and connection for the connector is disposed through the appropriate lower cushion sheet laminated on the lower ground. When there is unevenness (unevenness) on the surface of the foundation, such as when using an existing floor surface decorative material as a foundation, it is necessary to use an appropriate lower cushion sheet having a thickness that can absorb the irregularity. place a heat source equipment Te.
[0011]
The heater is arbitrary as long as it uses electricity as an energy source, and includes not only a planar heater or linear heater using a nichrome wire or the like as a resistor, but also a PTC heater mainly containing a ceramic semiconductor BaTi. In the case of a linear heater, it is also included that it is fixed in a meandering or looping manner on a suitable substrate. The heater, required wiring, connector for connection, and the like are fixed to the base with an appropriate fixing tool such as staple, if necessary.
[0012]
When the heat source equipment is disposed, unevenness (unevenness) occurs due to the heater, required wiring, connection connectors, and the like. Therefore, for the purpose of absorbing the unevenness, an upper cushion sheet having a thickness capable of absorbing the unevenness and preferably having approximately the same area as the ground area is laminated on the heat source equipment. Then, an appropriate surface decoration material is laminated on the upper cushion sheet in the form of a so-called floor (floating floor) without using an adhesive or a fixture. Thereby, the electric floor heating structure according to the present invention is constructed.
[0013]
There is no limitation on the type of surface decorative material laminated on the upper cushion sheet, and any one that has been used in conventional floor structures (for example, the aforementioned wooden decorative floor material, sheet-like appropriate cushion material, resin sheet, Tile). When a large number of rectangular unit bodies are gathered together to form a floor, such as a wooden decorative floor material or tile, it is desirable to apply sene processing around each unit body so that they can engage with each other. The reason for adopting the floor structure is that it can be easily constructed without using a fixture such as a nail.
[0014]
In the present invention, the upper cushion sheet and the lower cushion sheet are formed by the heat source equipment as described above, or absorb the unevenness (unevenness) existing on the ground surface, and the members positioned higher (the upper cushion sheet In the case of the surface decorative material, in the case of the lower cushion sheet, the heat source material) is not affected by unevenness (unevenness), and an appropriate material having an appropriate thickness depending on the degree of the unevenness Is selected. As the material, a resin material such as a foamed synthetic resin such as polyurethane or polyolefin, or a material such as a nonwoven fabric made of synthetic fiber is suitable.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments. FIG. 1 is a partially cutaway perspective view for explaining an embodiment of an electric floor heating structure and its construction method according to the present invention, and FIG. 2 is a perspective view of the electric floor heating structure shown in FIG. A part is shown in cross section. FIG. 3 is a sectional view showing another embodiment of the electric floor heating structure.
[0016]
In the form shown in FIG. 1 and FIG. 2, a discarded base plywood 2 affixed on a joist 1 disposed on a suitable wooden frame or concrete floor is used as the base 10. Of course, if the required flatness can be ensured, the concrete floor itself may be used as the foundation. The heat source equipment 20 is disposed directly or using an appropriate fixing means on the discarded base plywood 2 that is the base 10. In this example, the electric heater 20 includes a heat wire heater 22 attached to a sheet 21 such as an aluminum foil having a heat insulating effect, a connection connector 23, and a wiring material 24 that connects the heat wire heater 22 and the connection connector 23. Such an electric heater 20 itself is conventionally known.
[0017]
In this type of electric heating device 20, the heat wire heater 22 can be as thin as about 1 to 2.5 mm in thickness, but in order to ensure electrical stability, as shown in FIG. The portions 23 and the wiring member 24 have a thickness of about 3 mm or more. Therefore, the upper surface side of the electric heating device 20 disposed on the discarded base plywood 2 does not become a flat surface, and unevenness (unevenness) is formed.
[0018]
In order to absorb the unevenness, a cushion sheet (upper cushion sheet) 30 such as a foamed synthetic resin sheet or a non-woven mat having a thickness of about 2 mm is spread over the electric heater material 20, and the surface decorative material is formed thereon. Conventionally, a wooden decorative flooring material known as 40 is laminated as a so-called floor without using an adhesive or a fixture. The presence of the cushion sheet 30 allows the wooden decorative flooring 40 to be spread in a state that is flat and does not easily peel off by simply placing the wooden decorative flooring 40. Since no adhesive or the like is used to fix the wooden decorative flooring 40, the laying operation is easy, and when the surface is damaged, the wooden decorative flooring 40 can be easily replaced. it can.
[0019]
Further, in the above example, since a plurality of electric heaters 20 can be electrically connected only by connecting the connection connector 23, no special electric work is required, and the workability of the entire electric floor heating structure is improved. Can also be simplified. Further, the electric heater 20 is disposed only at a necessary portion of the floor foundation surface (for example, 1/2 or 1/3 of the entire floor foundation surface) to perform electrical connection, and then the cushion sheet ( Since it is possible to easily construct the upper cushion sheet) 30 and further arrange and fix the wooden decorative flooring 40, various electric floor heating structures can be constructed on the same floor surface. It becomes possible to do.
[0020]
The embodiment shown in FIG. 3 is the same as the electric floor heating structure described with reference to FIGS. 1 and 2 in that the lower cushion sheet 50 is laminated on the base 10 and the heat source equipment 30 is arranged thereon. Is different. The lower cushion sheet 50 may be the same as the upper cushion sheet 30, and a foamed synthetic resin sheet, a nonwoven fabric mat made of synthetic fibers, or the like is used.
[0021]
This aspect is a particularly effective construction aspect when the surface of the base 10 is not a flat surface but has irregularities (unevenness). Examples of the base 10 in this case include not only an uneven floor base surface after the existing floor floor material is peeled off, but also an existing surface decorative material, for example, a wooden decorative floor material in a wooden floor, although not particularly illustrated. The surfaces of cushion materials, resin sheets, tiles, etc. on the cushion floor with carpets can be used as they are. Therefore, this aspect is particularly suitable when a new electric floor heating is to be introduced during renovation.
[0022]
