Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor finishing structure, and more particularly to a floor finishing structure having a floor heating system.

[0002]

In the conventional floor finishing structure, when a thin surface plate as a floor surface finishing material, that is, a veneer is simply attached to a wooden base plate, when the veneer is used for a long period of time, the veneer may be affected by fluctuations in atmospheric temperature and humidity. It is directly affected and frequently expands and contracts, which easily causes cracks.

Further, when a plurality of slits are formed from the bottom surface of the lower wooden base plate in order to suppress the propagation of sound waves, that is, vibrations, volatilization in the adhesive when the base plate and the projecting plate are attached. This part contracts due to volatilization of the components and the like, and conversely the bottom surface of the base plate having the slits is likely to expand, and the longitudinal ends of the base plate tend to warp upward.

In order to prevent the above-mentioned cracks, Japanese Patent Publication No. 40
-22480 can be bonded and integrated by interposing a woven cloth between the base plate and the veneer plate, and JP-B-47-29291 can be bonded and integrated by interposing non-sizing paper between the base plate and the veneer plate. However, it is not possible to sufficiently suppress cracks in the case where the temperature difference from the atmosphere becomes even more significant, such as when a floor heating system is provided, and especially for warping. This cannot be prevented.

Further, in order to prevent warping and waviness, Japanese Patent Laid-Open No. 7-324460 discloses that a decorative sheet such as a veneer is attached to the surface of a wooden substrate via an adhesive, and a large number of sheets are attached to the back of the wooden substrate. It is disclosed that after a slit is formed, a flexible sheet is attached to the back surface via an adhesive by pressing it with a pressing device. However, since the flexible sheet is adhered to the back surface, the vibration and soundproofing effects due to the slits are easily impaired.

According to the present invention, the floor surface finishing material is frequently expanded and contracted as in the case where the floor heating system is provided as described above, and it is suppressed even in a severe environment where cracks and warpage occur. Alternatively, the present invention provides a floor finishing structure having a soundproof effect.

[0007]

According to the present invention, a floor surface finishing material is formed by laminating a plurality of thin wooden boards with the orientation directions of the fibers thereof being different from each other, and further, the upper layer is made of the fibers. Floor finishing structure in which veneer plates are attached and integrated in different orientations. In the floor finishing structure, a wood base plate and a floor surface finish with a number of slits carved from the bottom side on a floor heating mat equipped with heating means. A laminate of a material and a laminated body, and a cushioning fiber mat is interposed between the floor heating mat and the slit engraved wood base plate,
Furthermore, a floor plywood is interposed between the floor heating mat and the cushioning fiber mat.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The veneer, as is well known in the art, is made of thinly sliced name wood with a thickness of 0.2 to 0.3 mm to less than 1 mm, and is usually attached to a base plate made of plywood to make wood on the floor surface. Gives the floor a unique look. However, as described above, in order to suppress the cracking of the veneer and the warp of the floor material in a severe environment such as the case where the floor heating system is provided, in the present invention, as the floor surface finishing material, a thin wooden thin plate similar to the veneer is used. It is essential that a plurality of layers, preferably three or more layers, are laminated with the fiber orientation directions different from each other, and the veneer is attached to the upper layer with the fiber orientation directions different from each other. To do. The thickness of the floor surface finishing material is 2
It may be about 3 mm.

The wooden base plate usually has three or more layers, for example, 5 to 7 layers.
Composed of layers of plywood. The thickness is not specified, but may be appropriately set within the range of 5 to 12 mm.

In order to impart soundproofness to the floor material, after attaching the wooden base plate to the floor surface finishing material, a depth of more than half or the entire thickness of the base plate is applied from the bottom side of the wooden base plate upward. Engrave a large number of slits. The slits can be arbitrarily designed such that they are parallel to the width direction of the plate, or even parallel to the longitudinal direction of the plate, and the slit spacing can be arbitrarily designed such as 10 mm to 100 mm.

In order to further improve the soundproofness, a cushioning fiber mat layer is arranged under the wooden base plate. The cushioning fiber mat is formed of a non-woven fabric, and preferably includes a pressure resistant fiber rich in compression resistance and impact resilience and an entangled fiber bridging between the pressure resistant fibers, and the fiber mat thickness is, for example, It is about 3 mm to 10 mm. The combination of the wood base plate having the slits and the cushioning fiber mat makes it possible to improve the soundproofing performance up to around 40 of the sound insulation grade LL50.

By constructing the floor material as described above,
Even if the floor heating mat is arranged in the lower part, the floor surface finishing material does not warp or crack, and excellent soundproofing can be imparted.

For example, it is made of plywood 6 having a thickness of 2.5 mm in which 4 and 5 are laminated.
When laminating these thin plates, different from the fiber orientation directions of the upper and lower thin plates, as an example, the fiber orientation direction of the projecting plate 2 is parallel to the long side direction of the finishing material 1 and the thin plate 3 below it is At right angles to the long side direction of the finishing material,
Further, in the lower thin plate 4, alternate layers are formed in parallel with the long side direction of the finishing material.

A plywood is also used in the wooden base plate 7 arranged immediately below the floor surface finishing material 1 to form the same alternating layers as described above. In this embodiment, the wood base plate 7 is a single plate 8, 9, 1.
Layers 0, 11, and 12 are laminated to have a thickness of about 6 mm. The wood base plate 7 is attached to the floor surface finishing plate 1, and then the slits 13 are formed over the depth of almost the entire thickness of the base plate 7. The slit spacing is 12 mm, for example.

A cushioning fiber mat 14 made of non-woven fabric having a thickness of 4 mm and a density of 30 kg / m ³ to 400 kg / m ³ is arranged under the wooden base plate 7. As the fiber mat 14, as described above, a material including pressure resistant fibers rich in compression resistance and impact resilience and entangled fibers bridging between the pressure resistant fibers can be suitably adopted.

In the present embodiment, the presence of the slits 13 formed in the wood base plate 7 and the cushioning fiber mat 14 makes it possible to suppress the sound insulation grade to about 45. Further, in this embodiment, a floor heating mat 15 is further arranged below the cushioning fiber mat 14. The floor heating mat 15 has a density of 1
The glass wool mat 16 of 50 kg / m ³ to 400 kg / m ³ is provided with a hot water pipe 17 as an example, and although not shown, it is more preferable to attach an aluminum foil to the surface layer of the glass wool mat 16 for good heat transfer. Devise the design such as

The cushioning fiber mat 14 is a floor heating mat.
In order to improve the transfer of heat radiated from 15, metal fibers, metal foil pieces, and other heat transfer promoting medium may be appropriately mixed and coexisted.

Further, the cushioning fiber mat 14 and the floor heating mat
When 15 is in direct contact with each other, both of them have flexibility, so that the sinking of the floor during walking tends to increase. On the other hand, such a harmful effect can be suppressed by inserting a waste plywood 18 having a thickness of, for example, about 4 mm between the cushioning fiber mat 14 and the floor heating mat 15.

With the above constitution, the floor surface finishing material does not warp or crack even after long-term use, and when the soundproofing function is added,
It can exhibit excellent soundproofing effect.
