んで歩行感が悪くなる欠点が新たに生じた。[Prior Art] It has recently become common practice to apply wood-based flooring materials directly to concrete floor surfaces. However, this type of flooring that is directly connected to concrete has poor sound insulation properties, so a thick cushioning material was pasted on the back side of the wood flooring to improve the sound insulation. However, when a thick cushioning material is applied, a new drawback arises: the flooring sinks when walking, making it uncomfortable to walk.

The present invention also relates to a method for manufacturing a sound-insulating wooden flooring material, which comprises adhering a cushioning material with holes at appropriate positions, and then injecting and solidifying a hot melt resin into the holes of the cushioning material.

In Figures 1 to 3, l is a wooden board, and a sheet 2 having sound insulating, vibration damping, or buffering properties, a perforated wooden board 3, and a cushioning material 4 are successively pasted on the back side of this wooden board l. Holes 5 are previously formed at appropriate positions in the buffer material 4, and hot melt resin is injected into the holes 5 and solidified. This hot melt resin 6 needs to be harder than the cushioning material 4 after solidification.

Examples include inorganic powder-filled rubber sheets, PVC sheets, etc., and those with a thickness of 0.8 to 2 cm are preferred, but are not limited to these. Examples of cushioning sheets include cushioning sheets such as rubber foams and olefin foams. It may be any sheet with good properties, and the thickness is preferably 1 to 21 sheets.

しく歩行感が悪くなる。As the cushioning material 4, polyolefin foam, rubber foam, etc. with a thickness of 3 to 15 mm are used. Among these, closed foam is preferable because it is waterproof and is less likely to collapse than open foam. If the length is less than 3 mm, it will not work well as a cushioning material, and if it exceeds 151 mm, the cushion will sink heavily when walking, resulting in poor walking sensation.
この緩衝材４の下面には多数の独立した凸部７が形成さ
れている。凸部７の直径は５〜３０層騰、高さは １〜
５■が好ましいが、これに限定されない。A large number of independent convex portions 7 are formed on the lower surface of this cushioning material 4. The diameter of the convex part 7 is 5 to 30 layers high, and the height is 1 to 30 degrees.
5■ is preferred, but is not limited to this.
また、凸部７の表面形状は円形以外に方形、三角形、多
角形いずれでもよいことはもちろんである。It goes without saying that the surface shape of the convex portion 7 may be rectangular, triangular, or polygonal in addition to circular.

うに緩衝材４の下面に凸部７を設けておけば両者の接触
面積が小さくなって遮音性が向上する。In general, the sound insulation properties of flooring materials tend to improve as the contact area between the concrete floor and the wood flooring material becomes smaller.If the convex portion 7 is provided on the lower surface of the cushioning material 4 in this way, the contact area between the two can be improved. becomes smaller and improves sound insulation.

衝材４よりも厚みを若干薄くした方が好ましい。Holes 5 are previously formed in the cushioning material 4 at appropriate positions, and hot melt resin is injected into the holes 5 and solidified. The hot melt resin 6 is generally injected by pouring the hot melt resin from above, but is not limited to this method.The hot melt resin 6 has the function of preventing the cushioning material 4 from sinking when walking. Therefore, it is necessary that the cushioning material 4 be harder than the cushioning material 4 when solidified. Further, it is preferable that the thickness of the cushioning material is slightly thinner than that of the cushioning material 4.

、また、図面では緩衝材４は基材ｌと外形がほぼ同一の
形状をした一枚のシートからなっているのが２枚のシー
トを突合わせて構成することもできる。This is because when the floor material is slightly depressed by the cushioning material 4 when walking, the sound insulation properties and walking feeling are better. However, depending on the hot melt resin with high elasticity, the thickness may be exactly the same as that of the cushioning material 4.
The diameter of the hole 5 drilled in the IIm material 4 is 5 to 100 am.
If it is less than 5 mm, it is difficult to manufacture, and injection of the hot melt resin becomes complicated, and if it exceeds 100 mm, the sound insulation properties of the flooring material may deteriorate. In addition, the hole 5 may of course be formed in a rectangular shape other than a circle. In the drawing, the cushioning material 4 is made of two sheets having almost the same external shape as the base material L. It can also be constructed by butting together sheets.

、あるいは両端に孔５がくるように緩衝材４に孔５を形

外に中央部にも穴５を設けてもよい。The hole 5 formed in the buffer material 4 is preferably formed at a location where the flooring material is expected to sink the most. Therefore, the flooring material generally sinks near the joint between the flooring materials. Since this is considered to be the largest area, it is preferable to form the holes 5 in the cushioning material 4 so that the holes 5 are located at one end or both ends of the base material in the longitudinal direction.Also, if the flooring material is long, the holes 5 are located at one end or both ends of the base material in the longitudinal direction. A hole 5 may also be provided in the center.

わされている。In addition, as shown in the drawing, a wooden board for the surface layer, a sheet with sound insulation, vibration damping, or sound insulation properties, and a perforated wooden board were combined into small pieces and assembled, and a cushioning material was pasted on the back side. The sound insulation properties are better than the large-sized ones that are not divided into small pieces. This is thought to be because it becomes difficult for sound to propagate in the divided parts. The wood board cut into small pieces as described above has a loose tongue processing on the end surface that allows for slight bending. They are bonded by pouring melt resin 8, and a sheet of cushioning material 4 is bonded to the entire back surface.

脂を注入固化させて所望の床材を製造した。[Example 1] Decorative plywood with a thickness of 4.0 liters, a rubber foam sheet with a thickness of 2.0 liters, and perforated plywood with a thickness of 4.0 liters and a hole diameter of 10 mm were attached via adhesive. After combining, cut this to a thickness of 1
Five long and thin rectangular plates measuring 0.2 m wide, 60 mm wide, and 800 mm long were manufactured, and five sheets were slightly shifted in the vertical direction and joined at male and female grooves to form a base material. The male and female grooves are slightly bent at the joints, and are loosely joined to conform to the unevenness of the base.In addition, hot melt resin, which is flexible after curing, is placed in the groove on the back of the joint. Next, as shown in Figure 2, five holes with a diameter of 20 liters were formed, one hole at each end of the elongated rectangular plate that made up this base material. After a cushioning material made of a single sheet of polyopine foam having a thickness of 5 cm was attached to the back side of the base material, a hot melt resin was injected into the hole and solidified to produce a desired flooring material.
