Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] When hard materials such as wooden floors are laid on the floor of a building, carpets and heating mats are laid on the floor to prevent cold in the winter, and this time you will suffer from dust, mites, and mold damage. Recently, there is a growing need to warm the flooring itself. The present invention relates to a built-in heating floor used for the floor of such a building, and more particularly, to a floor such as a large floor or a joist, which is complicated to construct from the floor of the building and causes a heat bridge. Abolish the pair,
The present invention relates to a heating floor in which a heat insulating plate F having excellent pressure resistance and excellent heat insulating performance is densely provided on a floor base, and a floor in which a surface heating element A is directly built in the upper surface is constructed.

[0002]

2. Description of the Related Art In a conventional heating floor, a heat insulating material to be laid in order to prevent heat from escaping to a floor base is soft. Therefore, as shown in FIG. In many cases, a heat insulating material f was sealed inside, and various heating elements were installed thereon, and a base plate 3 and a floor finishing material 4 were stretched over a pulling or joist N. Recently, a floor finishing material containing a heating element has been applied on a floor set containing a heat insulating material f. On the other hand, as the heating floor of the directly attached type, the present invention has been developed by the present inventor 4-437.
No. 26 “Wooden sound insulation heating floor” and the like, but heat loss due to lack of heat insulation performance has been pointed out in the process of practical use.

[0003]

The heat insulating material used for the heating floor generally cuts off the heat by the air contained in the material, so that the soft material is overwhelmingly large, and even if it is said to be a hard material, the heat is not applied to the local load. It is very weak and has a large expansion and contraction. For this reason, when these heat insulating materials f are laid on the floor base P for heat insulation of the heating floor, the floor sinks due to the deformation of the heat insulating material due to the upper load, so that the floor structure must be placed on the floor base. As a result, the heating floor was constructed after assembling the Daihiki and the joists N and enclosing the heat insulating material f. However, the heat insulation performance was not improved as expected because the floor set became a heat bridge.
Also, those with built-in surface heating elements on wooden floors as direct-attached heating floors, although cushioning materials are stuck on the bottom surface, they are too thick when considering the sinking of the floor surface, so they can not be used, Although workability was improved, lack of heat insulation performance was undeniable, and heat loss needed to be improved.

[0004]

Means for Solving the Problems The present invention has been made in view of the above, and a heat insulating plate having a new pressure-resistant strength has been eliminated by eliminating a floor assembly of a large floor and a joist N which has been indispensable in the configuration of a heating floor. As F, the heat-insulating plate F, in which the fibers are attached to the side surface of the flat plate 1 in the horizontal direction and the thin strips whose main fiber directions are almost vertical as the heat-insulating rim 2, is densely mounted on the floor base and attached. By constructing a floor with a built-in surface heating element A directly on the upper surface to form a heating floor, even if a floor set that is complicated to construct and causes a heat bridge is abolished, the pressure resistance of the heat insulating plate F itself can be reduced. It has become possible to obtain a heated floor with good heat insulation performance, which is easy to construct and supports the floor and upper load by strength.

[0005]

[Operation] As described above, heat insulation is generally performed by using the air contained in the heat insulation. However, the higher the heat insulation performance, the softer the pressure resistance and the lower the pressure resistance. Can not. In view of this, the present inventor previously developed a sound-insulating floor using the difference in pressure-resistant strength depending on the fiber direction of the fiberboard in Japanese Utility Model Publication No. 51-5241 "Soundproof floor". The vertical strip has the property that the fiber has a remarkably high pressure resistance as compared with the flat plate in the horizontal direction, but the thermal conductivity is the same as that of the flat plate having the same density in the horizontal direction. The present invention makes use of this characteristic and attaches a thin strip having a substantially vertical fiber direction to a heat insulating edge frame 2 on the side surface of a flat plate 1 in which fibers are arranged in a horizontal direction to form a heat insulating plate F. The heat insulating frame 2 acts just like a strong joist by tightly attaching and adhering the material on the floor base, and supports the floor material and the load placed thereon. In addition, since the heat insulation performance does not decrease, a floor structure that causes a conventional heat bridge is not required at all. The heating floor of the present invention, in which the floor is constructed by directly incorporating the surface heating element A thereon, has different heating characteristics depending on the insertion site of the surface heating element A.

[0006] For example, the heating floor according to the first aspect of the present invention comprises:
The surface heating element A is installed on the heat insulating plate F, the base plate 3 and the floor finishing material 4 are laminated on the upper surface thereof, and the floor surface is thick, and it takes time for the floor surface to warm. On the other hand, in the case of the second aspect, the surface heating element A is installed immediately below the uppermost floor finishing material 4 and is sandwiched by the base plate 3, so that the floor surface is easily heated. Has a characteristic that it is relatively easy to cool and is easily controlled by a temperature controller. Claim 3
In the embodiment, the surface heating element A is disposed immediately below the floor finishing material 4 and is sandwiched by the base plate 3 having the flexible sheet 6 adhered to the surface thereof. Further, the surface of the floor covering 4 is easily heated with high thermal efficiency.
