Abstract

PURPOSE:To be able to suppress the destruction of a heat source with a sharp knife etc. and also prevent the generation of a warp due to heat expansion and swelling accompanying humidity by constituting heating floor in such a way that a base material is attached n the bottom surface of a metal plate having a heat source through a such ion layer possible to absorb shear stress and on the top surface of the metal plate a wood floor material is attached through a cushion layer having the same property as before. CONSTITUTION:A steel plate 6 having a heat source 1 is adhered to polywood 7 as a example of a base material 4 with adhesive agent such as epoxy resin through a cushion layer 3. A wood floor material 5 is adhered to the top surface of the steel plate 6 having the heat source 1 through a cushion layer 3. The cushion layers have sufficient thickness and flexibility capable of absorbing shear stress based on elongation due to expansion of the plate 2 and swelling of the wood material 5 and the base material 4. As for the cushion layers 3, very flexible resin such as silicon or urethane, or polystyrene, or polyolefin-based foam materials are used and they should have high heat resistant property because they contact the heat source 1.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a wooden heating floor equipped with a mounting plate on the top of the floor having a heat source, and more specifically, the present invention relates to a wooden heating floor that has a heat source and is equipped with a mounting plate. This invention relates to technology for preventing warping of wooden heating floors due to swelling due to moisture absorption of the wood.

[Background Art] Conventionally, in heating floors in which a metal plate with a heat source is attached to a base material and a car vent or the like is attached on top of the metal plate, the surface layer of the carpet or the like may be damaged by falling sharp objects such as knives. 1 Breaking through a metal plate and breaking a heater wire as a heat source,
There are problems such as breaking heating pipes, and during heating, the metal plate is heated by the heat source, causing the metal plate to expand greatly against the base material to which it is attached, and when not heating, it may cause damage to the base material such as plywood. Due to the swelling of the carpet and base material due to the shrinkage of the carpet material and surface layer of the carpet, the carpet and base material expand more than the metal plate, and this expansion of the metal plate and swelling of the carpet and base material causes warping. There was a problem that this occurred.

[Object of the invention 1 The present invention has been made in view of such problems,
The purpose of this is to suppress the destruction of the heat source by sharp objects such as knives, and to prevent warping due to thermal expansion and swelling due to moisture, even though the metal plate is attached to the flooring or base material. Our goal is to provide a wood heating floor that does not cause heat generation.

[Disclosure of the Invention] In the wooden heating floor of the present invention, a base material 4 is attached to the lower surface of a metal plate 2 having a heat source 1 via a cushion layer 3 capable of absorbing shear stress, and the upper surface of the metal plate 2 is It is characterized by having a wooden flooring material 5 attached thereto through a cushion layer 3 capable of absorbing shear stress, and by configuring it in this way, the above object has been achieved. In other words, by attaching the wooden floor material 5 to the surface of the metal plate 2 having the heat source 1, it is possible to prevent the heat source 1 from being damaged by a falling ring of a sharp object such as a knife. The metal plate 2 having the heat source 1 and the base material 4 are 279
By attaching the metal plate 2 and the surface wooden flooring material 5 through the 27282 layer 3, thermal expansion of the metal plate 2 and the wooden flooring material 5 and the base material 4 can be prevented. It expands due to swelling/L! 13.3, and can prevent warping due to thermal expansion and swelling.

Embodiments of the present invention will be described in detail below based on the drawings.

A heat source 1 heated by electrical means such as electrically heated hot water, a wire heater, a surface heater, or a carbon heater
is adhered to the back surface of a steel plate 6 as an example of the metal plate 2 with an adhesive. In this way, the steel plate 6 having the heat source 1 is attached to the base material 4.
As an example, the cushion layer 3 is bonded to a wooden plywood 7 using an adhesive such as epoxy resin. A wooden floor material 5 is bonded to the upper surface of the steel plate 6 having the heat source 1 through a 27912 layer 3. The cushion layer 3 has a thickness and flexibility capable of absorbing shear stress caused by the expansion of the metal plate 2 and the elongation caused by the swelling of the wooden flooring material 5 and the base material 4. The cushion/II3 is made of a very flexible resin such as silicone, or a foam such as phrethane, polystyrene, or polyolefin, and since it is in contact with the heat source 1, it is highly heat resistant. be.

In this way, the metal @ 2 having the heat source 1 and the base material 4 are attached via the cushion layer 3 that absorbs shear stress, and the metal plate 2 and the wooden floor material 5 can also absorb shear stress. When the heat source 1 is on, the metal plate 2 is attached to the wooden flooring 5 as shown in FIG.
When a large amount of elongation occurs with respect to the wood floor material 5 or the base material 4, the elongation is absorbed by the cushion layer 3 and does not spread to the wooden flooring material 5 or the base material 4 side. Even if the flooring material 5 or the base material 4 absorbs moisture and swells, and the wooden flooring material 5 or the base material 4 extends greatly relative to the metal plate 2 in the off state, the elongation is absorbed and the metal Thermal expansion @2 and elongation due to swelling of the wooden floor material 5 and base material 4 are absorbed by the cushions N3 and 3, thereby preventing warping due to thermal expansion and swelling. Even if a sharp object such as a knife is accidentally dropped, the wooden floor material 5 on the surface prevents the sharp object from reaching the heat source 1 and protects the heat source 1. The wood heating floor A thus obtained is formed into a fixed size like a panel, and can be constructed on a concrete base (conpanel) or on a joist.

[Effects of the Invention] To summarize, the present invention has a wooden flooring material attached to the surface of the metal plate having the heat source, so that the heat source is prevented from being damaged by a falling ring of a sharp object such as a knife. In addition, the metal plate and the base material, which have a heat source, are attached via a cushion layer, and the metal plate and the surface wooden flooring are attached via the cushion layer. The cushion layer has the advantage of being able to absorb the thermal expansion of the board and the elongation due to swelling of the wooden flooring and base material, thereby preventing warping due to thermal expansion and swelling.
