Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a method for directly applying a sound insulating wood flooring material to a concrete floor surface.

[Prior Art] It has recently become common practice to apply wood-based flooring materials directly to concrete floor surfaces. However, this type of concrete flooring has poor sound insulation properties.

A thick cushioning material was attached to the back of the wooden flooring to improve sound insulation. However, when a thick cushioning material is applied, a new drawback arises: the flooring sinks when walking, making it uncomfortable to walk.

[Problem to be solved by the invention 1 This invention aims to solve the above-mentioned drawbacks and to provide a method of constructing a sound-insulating wooden flooring material that has excellent sound-insulating properties and has a good feeling when walking on it. [Means for solving the problem] The present invention provides a method for forming a material on the back surface of a base material, which has substantially the same shape as the base material,
When installing sound insulating wood flooring with cushioning material with holes in appropriate locations, filler that is harder than the cushioning material is fitted into one or more of the holes, and then the subfloor surface is Relates to a method of installing sound insulating wood flooring.

Hereinafter, the present invention will be explained in detail with reference to the drawings. In Figs. 1 to 3, 1 is a wooden board, and on the back side of this wooden board 1 is a sheet 2 having sound insulation, vibration damping, or buffering properties. Perforated wood board 3. Cushioning materials 4 are successively pasted together. Holes 5 are formed at appropriate positions in this buffer material 4.

Examples of the above-mentioned wood board l include plywood, particle board, hardboard, LVL (parallel plywood), etc., and a decorative layer can be formed by pasting a precious wood veneer or a decorative synthetic resin sheet on the surface, or by painting it. may be formed.

The thickness of the wood board 1 is preferably 2.5 to 4.0 mm, but is not limited thereto.

The sheet 2 attached to the back side of the wooden board l has sound insulation, vibration damping, or! It is a sheet having l# properties.

As sound insulation or vibration damping sheets, PVC sheets containing powdered lead,
Examples include inorganic powder-filled rubber sheets, PVC sheets, etc., and those with a thickness of 0.8 to 2 mm are preferred, but are not limited to these. Examples of 1M impact sheets include rubber foams, olefin foams, etc. Any sheet with cushioning properties is fine.
The thickness of the intestine is preferably 1 to 2 m.

The perforated wooden board 3 to be attached to the back side of the sheet 2 may be plywood, particle board, or hardboard.

LVL etc. can be used. The thickness is preferably 2.5 to 4.0 mm, and the hole diameter is preferably 5 to 15 mm, but is not limited to these.

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 has excellent waterproof properties and is less likely to collapse than open foam. If the length is less than 3 cm, it will not work well as a cushioning material, and if it exceeds 15 cm, the material will sink heavily when walking, resulting in poor walking sensation.

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 haze layers, and the height is 1 to 5
(2) is preferred, but is not limited thereto.

In addition, the surface shape of the convex portion 7 is not only circular but also rectangular, -(square,
Of course, any polygonal shape may be used. 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.

Holes 5 are formed in the buffer material 4 at appropriate positions.

A filler 6 that is harder than the cushioning material 4 is fitted into the hole 5 during construction. This filler 6 has the function of stopping the cushioning material 4 from sinking when walking, and therefore needs to be made of a harder material than the cushioning material 4. Suitable materials include synthetic resin foam, natural rubber, synthetic rubber, cork, and wood. In addition, it is preferable that the thickness of the cushioning material 4 is slightly thinner than that of the cushioning material 4, because it is better to have the floor material sink slightly into the cushioning material 4 when walking, for better sound insulation and a feeling of walking. It is. However, depending on the material with high elasticity or stiffness, I
Of course, the thickness of the hole 5 formed in the cushioning material 4 may be exactly the same as the thickness of the cushioning material 4. It is preferable that the diameter of the hole 5 formed in the cushioning material 4 is 5 to 100 layers. It has the disadvantage that a large number of fillers are required to prevent crowding, and if more than 100 layers are used, the sound insulation properties of the flooring material may deteriorate. Further, the shape of the hole 5 may of course be rectangular instead of circular.

It is preferable that the holes 5 formed in the cushioning material 4 be formed at a location where the flooring material is expected to sink the most or at a location where the flooring material should not sink. It is preferable to form holes 5a, 5b, and 5c near the joint with the flooring material, in other words, at both ends of the flooring material and at the center of the flooring material, but the hole 5 is not limited thereto. During construction, the filler 6 is fitted through an adhesive or the like, but it is not necessarily necessary to fill all the holes 5. For example, it is possible to fill only the row of holes 5a, or fill the rows of holes 5a and 5c. You can select as appropriate, such as filling only columns. Also, hole 5
Fill hole 5b at the site and fill hole 5b during construction on site.
It is also possible to fill in the columns.

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. Wooden boards cut into small pieces like those used in upper baths have loose tongues on the end surface that allow for young bending, and the grooves on the back created by the tongue and groove joints provide flexibility after hardening. A hot-melt resin 8 is poured thereinto to bond them, and a sheet of cushioning material 4 is bonded to the entire back surface thereof. The cushioning material 4 may be constructed by butting two sheets together as shown in FIG. 2. In this way, the cushioning material 4 can be efficiently cut into a special shape and used. Available.

[Example 1] Size 30 cm x 90 cm, thickness 4.0 mm decorative plywood, thickness 2.0 wet rubber foam sheet, thickness 4.0 mm, perforated plywood with hole diameter 10 mm, A flooring material made by sequentially bonding cushioning material with five holes of 25 layers in diameter at regular intervals to both ends of a polyolefin foam with a thickness of 5.0 mm in the longitudinal direction using an adhesive. When carrying out construction on site,
A synthetic rubber filler having a thickness of 5 mm was fitted into only the holes on one side of the cushioning material and then installed to obtain the desired floor surface.

[Example 2] After sequentially pasting together the decorative plywood, foam sheet, and perforated plywood used in Example 1, this was cut into pieces with a thickness of 10 cm and #1.
! A long and narrow rectangular board with a length of 60 mm and a length of 800 mm was manufactured, and five of these 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, holes 5a, 5b, and 5c each having a diameter of 30 mm are made so that one hole is made on the long and thin rectangular plate that makes up this base material. A cushioning material made of a single sheet of polyopine foam having a thickness of 5 mm was laminated to the back surface of the base material to produce a flooring material. When constructing this flooring material on-site, a low-foam foam with a thickness of 4 ms was applied to all the holes 5a on one side (on the left side of the drawing) of the holes in the cushioning material and the holes on the outside of the hole 5c in the center. After the polyophine filler was fitted, it was bonded to the subfloor surface using an adhesive to obtain the desired floor surface.

[Effects of the invention] As detailed above, when installing sound-insulating wood flooring, a filler harder than the cushioning material is fitted into appropriate locations of the holes formed in the cushioning material pasted on the back surface. By doing so, it is possible to obtain a wooden floor surface with excellent sound insulation properties and a pleasant walking sensation.
