The plurality of small joists are arranged in parallel to each other and arranged in one direction. The floor board is provided in a direction orthogonal to the longitudinal direction of the small joists, but the end in the longitudinal direction of the floor board is provided so as to be located on the small joists.
JP 2003-166720 A

  However, in the conventional floor heating mat, a plurality of small joists are provided in the same direction (one direction) in parallel with each other, so the floorboard is provided in the other direction so as to be orthogonal to this, but the same as the small joists If an attempt was made to provide one of the directions, there would be a place where there was no small joist under the floor board, so that the floor board could not be provided in one direction. Thus, the direction of the longitudinal direction of the floor board is inevitably determined when the direction of the small joists of the floor heating mat is determined, and the laying direction of the floor board is determined regardless of the direction of the small joists of the floor heating mat laid in the room. The degree of freedom in the direction of stretching the floorboard was narrow.

  The subject of this invention is expanding the freedom degree of selection of the tension direction of a floor board.

  In order to solve the above problems, the present invention is a floor heating mat that is laid under a floor board and heats the space on the floor board by heating the floor board, and has a mat-like base material having elasticity, A heating means provided on or in the surface of the base material and capable of generating heat electrically, and a small joist provided on the base material including the heating means, and the small joists are provided in a lattice shape. It is characterized by.

  By doing in this way, since the small joists of the floor heating mat are provided in a lattice shape, the floor boards can be laid with the longitudinal ends of the floor boards positioned on either of the small joists orthogonal to each other. . That is, the floorboard can be laid in one direction or the other direction regardless of the orientation of the floor heating mat itself.

  Moreover, since the base material is elastic and mat-shaped, when the floor board is laid on the floor heating mat, the base material is in close contact with the back side of the floor board. When the heating means is provided on the surface of the substrate, the heating means is also in close contact with the back side of the floor board. Since the base material and / or the heat generating means are in close contact with the back side of the floor board, the heat generated by the heat generating means is easily transferred to the floor board, thereby improving the efficiency of floor heating.

  Next, each requirement constituting the present invention will be described in more detail. The floor heating mat of the present invention is laid so as to be in close contact with the back surface of the floor board and is provided on the floor base material, and utilizes the heat generated by the heating means provided on the surface or inside of the base material. The floor board is heated and the upper space of the floor board is heated.

  The base material is an elastic or compressible mat-like material and has a thickness of several millimeters such as a nonwoven fabric, a net-like sheet, paper, a perforated sheet.

  The heat generating means can generate heat electrically and has a linear shape (electric heater wire), a planar shape (surface heating element), and the like. The heat generating means is provided by being stuck on the surface of the substrate or embedded in the inside. Furthermore, the heating means may be provided for each of the small joist lattices, or may be provided over substantially the entire surface of the substrate. When an electric heater wire is used as the heat generating means and it passes under the small joist, it is preferable to form a notch groove through which the heater wire can pass under the small joist. In addition, it is good to provide a heat sensitive wire (sensor wire) along this in the vicinity of the heat generating means. By providing a heat sensitive wire, the temperature of the floor board is controlled and overheating is prevented.

  The small joists are provided in a lattice shape, and elongated materials may be connected in a vertical and horizontal lattice shape, or a plate-like material may be formed in a lattice shape by punching. The small joist is fixed to the floor base plate with a screw or the like through the base material. Since the base material has elasticity, the base material located under the small joist is compressed.

  The shape of each small joist is not particularly limited, but generally a strip-like or strip-like plate having a rectangular cross section or a rod-like material may be used. For the small joist, a material that can sufficiently withstand the compressive force applied to the floor board is used, but a material having bendability or flexibility is preferable. When the small joists have bendability or flexibility, the floor heating mat using the lattice-like small joists can be wound compactly, and transportation, transportation and handling are easy. The small joists that have bendability or flexibility are made of wood, such as plywood, wood board, wood fiber board (MDF, etc.), wood chipboard, and single board laminated board, synthetic resin, iron, copper, Metal type such as aluminum alloy.

  The floor heating mat of the present invention is preferably provided with a heat dispersion sheet that disperses heat generated by the heat generating means over the entire surface of the base material including the heat generating means. The heat dispersion sheet is located under the small joists. By providing the heat dispersion sheet, the portion of the floor plate corresponding to the floor heating mat is heated over the entire surface, thereby improving the efficiency of heating.

  The heat dispersion sheet is not particularly limited as long as it has flexibility and good heat conductivity. For example, a metal thin plate or a metal foil is applied to the surface of a sheet formed of a nonwoven fabric such as spunbond, a net, or paper. Adhesion or two of these sheets may be prepared, and a thin metal plate or metal foil may be sandwiched between the two sheets.

  For example, vinyl acetate, vinyl acetate / acrylic, ethylene / vinyl acetate, acrylic / ethylene, urethane, or the like is used as an adhesive for sticking the heat generating means or the heat dispersion sheet to the base material.

  According to the present invention, since the small joists are provided in a lattice shape, the end of the floor board can be laid on the small joists regardless of one direction or the other direction, and the selection of the tension direction of the floor board Of freedom.
