In addition to the invention according to claim 1, it is preferable that the wood-based soundproof flooring material according to claim 4 further has a buffer material attached to the back surface of the wooden flooring material. As the buffer material, a synthetic resin foam such as polyurethane or polyethylene foam, a fiber mat in which a polyester fiber, a polypropylene fiber, a nylon fiber or the like is formed into a mat shape can be used.

  The wooden soundproof flooring according to the first aspect of the invention is as described above, and a plurality of U-shaped deep groove portions perpendicular to the length direction are formed on the back surface of the wooden flooring that is the base material. Since a recess that is engraved at an interval and has a depth shallower than that of the deep groove portion on the plane including the deep groove portion so as not to overlap is disposed between the deep groove portion and the deep groove portion, This prevents the back of the base material from touching the floor surface of the body and prevents the foot from sinking, and has an effect of excellent walking feeling. Moreover, since the rigidity of the wooden floor material is not impaired, the workability during construction is excellent without being damaged during transportation. Furthermore, the recessed part shallower than the deep groove part exhibits the soundproofing performance, and for example, even if an object is dropped from above, it is prevented from being transmitted as noise to the downstairs.

And since the shape of the said recessed part is made circular in planar view, it becomes possible to provide this circular recessed part in the back surface of many wooden type floor materials, without overlapping, and a soundproofing effect can be improved.

The wooden soundproof flooring material according to claim 2 is as described above, and in addition to the effect of the wooden soundproofing flooring material according to claim 1, the width of the deep groove portion is in the range of 1 to 4 mm, from the back side. The depth of the wooden flooring is in the range of 4/9 to 7/9, and preferably the depth from the back side is about 2/3 of the thickness of the wooden flooring. The stiffness of the flooring material is not softened, the rigidity is maintained, and an excellent walking feeling can be obtained.

The wood-based soundproof flooring material according to claim 3 is as described above, and in addition to the effect of the woody soundproofing flooring material according to claim 1, the depth from the back surface side of the concave portion is 1/9 to 5/9. Preferably, since the depth from the back side is about 1/3 of the thickness of the wooden flooring, the two-step structure of the deep groove portion and the shallower concave portion is used, and walking The soundproofing performance can be improved without deteriorating the feeling.

The wood-based soundproofing flooring according to claim 4 is as described above, and in addition to the effects of the woody soundproofing flooring of claim 1, a buffer material is further adhered to the back surface of the wooden flooring. Further, it is possible to obtain a wood-based soundproof flooring material having better walking feeling and soundproofing performance.
