Description

Detailed Description of the Invention 【Technical field】

The present invention relates to a technique for preventing a soundproof flooring material from sinking when a soundproofing floor material having soundproofing and vibration-proofing functions is installed.

[Background technology]

When a conventional floor material receives an impact, there is a problem that vibration is transmitted to the floor base material of the building along with the floor material, and this is transmitted to the lower floor, which is not preferable in terms of soundproofing. For example, in an apartment building or the like, there is a problem that if a child runs around on the upper floor, people on the lower floor may complain about it. Therefore, as shown in FIG. 5, a cushioning member 4 is laminated on the back surface of the flooring material main body 3 to prevent noise by the action of the cushioning member 4. Soundproof floor material 5 having such a configuration
Place the soundproof floor material 5 on the floor base material 6, and
The nail 8 is driven from the fitting projection 1 portion provided at one end of the base to be fixed to the floor base material 6, but when the nail is driven, the cushion material 4 portion is compressed and this portion is fixed. However, there was a problem that the wavy phenomenon occurred due to the fact that it was sunk as it was and was constructed as shown in FIG.

[Object of the Invention]

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a cushioning material at the time of fixing by nailing even though a cushioning material is laminated on the back surface to provide soundproofing performance. It is an object of the present invention to provide a method of constructing a soundproof flooring material which can be constructed so that the soundproofing floor material will not be partly sunk by being compressed, and the corrugation phenomenon can be prevented.

DISCLOSURE OF THE INVENTION

The soundproof floor material construction method of the present invention is provided with a fitting projection 1 projecting laterally at one end and a fitting recess 2 having a shape fitting the fitting projection 1 at the other end. A cushioning material 4 is laminated on the back surface of the provided flooring material main body 3 to form a soundproof flooring material 5, the soundproofing floor material 5 is placed on a floor base material 6, and then the floor base material 6 In a state where the contact plate 7 is inserted between the fitting protrusion 1 and the fitting protrusion 1, the nail 8 is driven from the upper surface side of the fitting protrusion 1 while avoiding the contact plate 7 to fix the nail 8 to the floor base substrate 6, and thereafter. To remove the backing plate 7 and then to the fitting projection 1 to the fitting recess 2 of another soundproof flooring 3.
It is characterized in that the above-mentioned conventional problems are solved and the object of the present invention is achieved by adopting such a configuration. That is, according to the present invention, the nail 8 is avoided from the upper surface side of the fitting projection 1 while the fitting plate 7 is inserted between the floor base material 6 and the fitting projection 1. By striking and fixing the nail 8 to the floor base material 6, the fitting projection 1 is supported by the backing plate 7 when striking the nail 8, and as a result, the cushioning material 4 does not move even when the nail 8 is driven. The soundproof flooring 5 is not compressed and is designed so as not to be partially depressed, and the fitting recess 1 of another soundproofing floor 5 is fitted to the fitting protrusion 1 which is not depressed. The fitting recess 2 side is also designed so as not to sink when it is connected. Hereinafter, the present invention will be described in detail with reference to Examples. The flooring body 3 has a fitting projection 1 projecting laterally from one end and a fitting recess 2 shaped to fit the fitting projection 1 at the other end. It is set up. Here, in the embodiment of the attached drawings, the fitting protrusions 1 are provided on a pair of adjacent sides of the four sides, and the fitting recesses 2 are provided on another pair of adjacent sides, but at least one side end It suffices that the fitting protrusion 1 is provided on the first end and the fitting recess 2 is provided on the other end. A cushioning material 4 made of synthetic resin foam, natural rubber or the like is laminated on the back surface of the flooring material main body 3 to provide a soundproof flooring material 5.
Is formed. The soundproof flooring 5 having the above structure is constructed as follows. That is, first, as shown in FIG. 1 (a), the soundproof floor material 5 is placed on a floor base material 6 such as concrete slab or plywood, and then as shown in FIG. 1 (b). A contact plate 7 is inserted between the base material 6 and the fitting protrusion 1, and the contact plate 7 is inserted from the upper surface side of the fitting protrusion 1 as shown in FIG. Avoid the plate 7 and nail 8
The bottom of the nail 8 is fixed to the floor base material 6 by driving it obliquely. In this case, even if the nail 8 is driven in, the fitting protrusion 1 is supported by the contact plate 7 and the cushion material 4 does not shrink,
This part does not partially sink. After that, the contact plate 7 is pulled out, and then the fitting recess 2 of the other soundproof flooring 3 is fitted to the fitting projection 1 as shown in FIG. 1 (d). After that, the same work is repeated to construct the soundproof flooring 5 one after another. The thickness of the contact plate 7 is set to be substantially equal to the distance from the lower surface of the fitting protrusion 1 to the lower surface of the cushion member 4.

【The invention's effect】

In the present invention, as described above, the soundproof floor material is placed on the floor base material and then fitted with the backing plate inserted between the floor base material and the fitting projection. From the upper surface side of the protrusion, hit the nail avoiding the backing plate to fix the nail to the base material of the floor, then remove the backing plate, and then fit the fitting recess of another soundproof floor material into the fitting protrusion. Since the fitting projections are supported by the backing plate during nailing, the cushioning material is not compressed even when the nails are driven, and the soundproof floor material is prevented from partially sinking. The wavy phenomenon can be prevented, and by fitting the fitting recess of another soundproof floor material to the fitting protrusion that is not sinking, it is possible to prevent the fitting recess side from sinking when the connection is made. It is a thing. Further, since the backing plate is removed, the backing plate does not remain and the soundproof performance is not deteriorated.
