Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a floor finishing material used as a building interior material. It is known that a surface finishing material made of a relatively hard material such as wood or synthetic resin is attached to the subfloor. When a resident walks on such a floor, the sound of walking is transmitted downstairs, causing noise to the residents downstairs. Therefore, attempts have been made to use carpet as a surface finishing material to block floor impact noise.Furthermore, in order to reduce the sound of children running and jumping, the structure of the floor base has been devised. The so-called floor type unit panels were used to support the floor base panels with support bolts.

[Problem to be solved]

Conventional surface finishing materials that use carpet have recently been avoided because carpet is a breeding ground for dust mites, stains are easily visible, and cleaning is difficult. Surface finishing materials made of hard materials are being reconsidered. When such surface finishing materials are used, floor impact noise tends to be transmitted downstairs, so there is a demand for floor finishing materials themselves that have floor impact sound blocking properties, rather than as a subfloor structure. .

Therefore, an object of the present invention is to provide a floor finishing material with improved sound insulation performance.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides S! A thrust layer was formed.

(Function) When using the floor finishing material according to the present invention, even if various impacts are applied to the floor, they will not be directly transmitted from the surface finishing material to the subfloor.
On the back side of the surface finishing material! 111W1 absorbs shock and prevents sound propagation.

[Embodiments] Preferred embodiments of the present invention will be described below with reference to the drawings.

In the first embodiment shown in FIGS. 1 and 2, a male fruit 1A and a female fruit 1B are formed on the side surface of a surface finishing material 1 made of parquet plywood. A large number of surface finishing materials 1 are arranged so that male seeds 1A and female seeds 1B are matched with each other. A buffer layer 2 made of various plastic foams such as polyurethane foam, polyethylene foam, and vinyl chloride foam, a soft molar plate such as an insulation board, and an inorganic fiber material such as glass wool is attached to the entire back surface of the surface finishing material 1. , as the M-plane layer 2, felt can also be used with the aim of preventing fraying.

Further, the IIWJ 12 may have a multilayer structure made of several materials. Note that the surface finishing material 1 has a finishing layer 11
It has a two-layer structure of a plywood layer 12 and a plywood layer 12.

FIG. 3 shows the second embodiment, ! The 11f layer 2 is attached so as to protrude outward from the male seed 1A, and another surface finishing material 1 is placed on the protruding buffer layer 2, and the surface finishing material 1
This is intended to prevent the squeaks of the male and female fruit IA and 1B at the butt part (joint part).

FIG. 4 shows a third embodiment, l1iJ! 2 is for example MH
21 with fiber material 21 and polyurethane foam 22
! ! Indicates the size of what is made of.

FIG. 5 shows a fourth embodiment, in which a material 3 suitable for adhesion to the flooring base, such as wood or rubber, is attached to the back surface of the M-surface layer 2.

FIG. 6 shows a fifth embodiment, in which a recess 1C is formed in place of the male seed 1A and fi seed 1B.

FIG. 7 shows a sixth embodiment, in which the surface finishing material 1 is coated with a finishing layer 11.
It is constructed from only one piece and has a phase cutout 1C formed therein.

FIG. 8 shows the seventh embodiment, in which a groove 1D is dug in the side surface of the surface finishing material 1, and the grooves are lined with thin azure (not shown) of a size that matches the groove. .

FIG. 9 shows the eighth embodiment, in which 1MN82 is used as the surface finishing material 1.
It is not attached to the entire back side of the camera, but only partially. In this embodiment, the four M holes 2 are attached in the transverse direction of the surface finishing material 1, but they may be attached in the longitudinal direction or in the form of a large number of dots.

Examples in which the first to eighth embodiments described above are combined are also possible. In either embodiment, the static spring deflection characteristic is 3 for a local concentrated load of 1QQcnu.
0 kg, /cvi-cm2 or less is suitable. For that purpose, surface finishing material 1 and loose [rJi! The thickness and budget of i2 are selected.

The above-mentioned first embodiment and the surface finishing material only except for the buffer layer 2 in the first embodiment are used for a conventional wooden large joist type flooring (this flooring is a concrete slab of an apartment complex). Fig. 10 shows a comparison of the sound insulation performance when attached to the top (constructed above).

The measuring method is based on the tapping machine method specified in JIS A-1418. floor! ! ! Sound levels were measured downstairs. L-40 Mustard-60 indicates the sound insulation grade, and each grade indicates how the sound of footsteps and running around is perceived as follows.

L-40...I can hear it from a distance L-45...
...I can hear it but it doesn't bother me L-50...I don't really care L-55...I'm a little concerned L-60...I'm a little concerned L-65... As is clear from Figure 10, the ladder grade of the first embodiment of the present invention is two ranks higher than that of conventional floor finishing materials. be. In addition, the static spring of the first embodiment has a load of 30 kg/am-a for a local concentrated load 1iiooc1.
It has a spring constant of m2 or less.

〔effect〕

As explained above, according to the present invention, since the buffer layer is formed on the back side of the surface finishing material made of relatively hard material such as wood or synthetic resin, the floor finishing material itself has floor impact sound blocking performance. can be imparted, and floors using this material have excellent sound insulation properties. It also improves the feeling of walking.

Static spring of floor finishing material - deflection characteristics - local concentrated load 100
If the spring constant is 30 kQ/cm-am2 or less for 0I12, the sound insulation property against floor impact sound, especially light impact sound, is ensured.

Therefore, when the floor finishing material of the present invention is attached to a subfloor structure that supports the subfloor panel with support bolts equipped with raised cushion rubber, the cushion rubber mainly absorbs the weight impact sound and the II impact noise. It is possible to block mainly light impact sound and block floor impact sound very effectively.

Further, when the buffer layer is formed as a multilayer of two or more layers made of materials with different properties, the properties of each material work together to provide a sound insulation effect suitable for the construction situation.

In general, when the II bumps 1 are partially formed on the back side of the surface finishing material, not only the material cost is reduced, but also ventilation is improved.
