Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a flooring material with a soundproofing function and a construction method thereof.

[Background Art] Conventionally, a flooring material made of a plywood substrate with a decorative laminate applied thereto was placed directly on a building floor base material such as a slab. For this reason, in the past, when a shock was applied to the flooring material, vibrations were transmitted through the flooring material to the floor base material of the building, and this was transmitted to the lower floors, which was not desirable in terms of soundproofing.

[Object of the Invention] The present invention was invented in view of the above points, and its purpose is to provide a soundproofing function to the flooring material itself, and to make it possible to provide a soundproofing function to the flooring material itself. To provide a flooring material which can soundproof not only the material but also the elastic base material part and further ensures soundproofing, and a method for constructing the same.

[Disclosure of the Invention] The present invention comprises a floor material main body 4 in which an elastic sheet 2 is laminated on the back side of a wood decorative board 1 and a substrate 3 is laminated on the back side of the elastic sheet 2. Cut grooves 5 are provided in the substrate 3 of the floor material body 4. The specified invention provides a floor material characterized by A substrate 3 of a flooring main body 4 in which elastic sheets 2 are laminated and a substrate 3 is laminated on the back side of the elastic sheet 2.
A combined invention is a method for constructing a flooring material, which is characterized in that a flooring material 9 configured by providing a cut groove 5 is placed on the flooring material,
By employing such a configuration, the above-mentioned object of the present invention is achieved. That is, in the flooring material of the present invention, the first stage of soundproofing can be achieved with the elastic sheet 2, and the substrate 3
The second stage of soundproofing is achieved by providing the grooves 5 in the flooring material 9. Furthermore, in the flooring construction method of the present invention, in addition to soundproofing by the flooring material 9 itself, the flooring material 9 Soundproofing can be achieved by the elastic base material 8 having a through hole 7 on which it is placed, and the elastic base material 8 allows the floor base material 6 of the building to be
Even if there is some unevenness on the top surface, it can be accommodated and the construction can be carried out accurately.

The present invention will be explained in more detail from Example 1 below. An elastic sheet 2 is laminated on the back side of a wooden decorative board 1, and a base @3 is laminated on the back side of the elastic sheet 2. A cut groove 5 is provided in the base @3 of a flooring main body 4, so that the flooring material 9 is finished. .

Here, the wood decorative board 1 is made by laminating, for example, a wood decorative veneer 1b on a plywood 1a. Wooden makeup @ 5th for 1
As shown in the figure, the surface gutter 10 may be provided only in the decorative veneer 1b in the longitudinal direction to the middle direction of the floor material body 4, or as shown in FIG. 4 may be provided in the longitudinal direction or in the middle direction.

The surface side groove 10 is a ■ groove or a U groove. By providing the surface gutter 10 in this manner, the degree of freedom of the floor material 9 is increased, and floor impact noise can be further reduced. As the elastic sheet 2, for example, a rubber sheet is used. Also, the group Fi
For example, plywood is used as the material 3. And this group @3
The one cut groove 5 on the back side is a decoration. This kerf 5 is cut upward from the back side of the substrate 3, and is cut into the elastic sheet 2.
It is a struggle to cut until the elastic sheet 2 is reached, or to a state where the elastic sheet 2 is not reached. Here, cutting grooves 5 having different cutting depths may be used in combination. Further, one or more kerfs 5 may be provided in parallel to the longitudinal direction of the flooring body 4, or one or more kerfs 5 may be provided in the width direction of the flooring body 4, or in the longitudinal and width directions of the flooring body 4. One or more pieces may be provided in each direction, or one or more pieces may be provided in a diagonal direction with respect to the longitudinal direction of the floor material body 4, or a diagonal lattice shape diagonal with respect to the longitudinal direction of the floor material body 4. It may also be provided. By the way, by providing the kerfs 5 in this manner, the vibration energy of the sound transmitted through the floor material body 4 can be attenuated at the kerfs 5 portion. A fitting protrusion 11 is provided on one side of the flooring 9 in the longitudinal direction, and a limiting recess 12 is provided on the other side. This fitting protrusion 81S11 and throat fitting recess 12 are made of Pt.
The elastic sheet 2 may be provided at the base @3 as shown in FIG. 51, or the elastic sheet 2 may be located in the middle as shown in FIG.

Therefore, the floor material 9 having the above-mentioned structure can be installed directly on the floor base material 6 such as a slab of a building, or alternatively, as in the construction method according to the combined invention of the present invention, the floor material 9 can be installed directly on the floor base material 6 such as a building slab. An elastic base material 8 having a large number of through holes 7 is laid on top of the base material 6, and a floor material 9 is laid on top of the elastic base material 8. Here elastic base material 8
As shown in Fig. 7, a board made of synthetic resin foam or rubber has many holes penetrating it vertically, or as shown in Fig. 8, it is made of synthetic resin foam. An elastic mesh made of body material or rubber is used. By using the elastic base material 8 having a large number of through holes 7 as a base material, the elastic base material 8 itself attenuates the vibrational energy of the sound, and the presence of the through holes 7 also reduces the vibration energy of the sound. It attenuates it.

[Effect of the invention 1] In the present invention, as described above, an elastic sheet is laminated on the back side of a wood decorative board, and a groove is provided in the substrate of the flooring main body in which a substrate is laminated on the back side of the elastic sheet. The first stage of soundproofing can be achieved using an elastic sheet, and the second stage of soundproofing can be achieved by providing grooves on the substrate, thereby providing a flooring material that can provide reliable soundproofing. In addition, in the combined invention, an elastic base material having a large number of holes is laid on the floor base material of the building, and an elastic sheet is laminated on the back side of the wooden decorative board on top of the elastic base material, and the elastic sheet is laminated on the back side of the elastic sheet. Since the flooring material is constructed by providing grooves in the substrate of the flooring material itself, in which the substrate is laminated, in addition to the two-stage soundproofing provided by the elastic sheet of the flooring material itself and the grooves in the substrate, the flooring material is The elastic base material has a through-hole for installation, making it possible to achieve soundproofing.The elastic base material also allows for accurate construction by absorbing slight irregularities on the upper surface of the building's floor base material. It is possible.
