DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof floor material for forming a soundproof floor in a house.

[0002]

2. Description of the Related Art A soundproof floor panel 2 as shown in FIG. 2 is provided by the present applicant as a floor material for forming a floor in a room in order to prevent floor sounds such as footsteps from being transmitted downstairs. Have been. The soundproof floor panel 2 is formed by providing a plurality of vibration absorbing grooves 1 at predetermined intervals on the lower surface of the plate member 8. Even if a shock is applied to the soundproof floor panel 2, vibration due to the shock is absorbed. The sound is absorbed by the groove 1 and can be prevented from propagating the sound downstairs.

The sound absorbing floor panel 2 formed by providing the vibration absorbing groove 1 on the lower surface as described above is weakened by the vibration absorbing groove 1 and cannot withstand a load. Is installed on the floor to form a soundproof floor, a plurality of floor boards such as plywood are laid over the joists and attached, and then the soundproof floor panel 2 is placed on the floor base. I am trying to fix it.

[0004]

However, if it is necessary to attach the floor slab to the joists as described above, there is a problem that extra work is required for the construction of the floor. If there is a step between them, there is also a problem that the soundproof floor panel mounted thereon rises or stomps.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a soundproof floor material capable of performing floor construction without having to perform a work of attaching a floor base plate.

[0006]

The sound-insulating floor material according to the present invention forms a sound-insulating floor panel 2 by cutting a plurality of vibration-absorbing grooves 1 on the lower surface and forms one end of the sound-insulating floor panel 2.
The connecting male 12 and connecting female 13 are placed on the surface and the other end face.
The fittings 1 are provided on one end face and the other end face of the substrate 3 respectively.
4 and mating female nuts 15 are provided, respectively,
The end provided with the fruit 14 projects from the end of the soundproof floor panel 2
The soundproof floor panel 2 on the substrate 3
It is characterized by being embodied .

[0007]

Since the soundproof floor panel 2 is laminated and integrated on the substrate 3, the soundproof floor panel 2 can be reinforced by the substrate 3 to support a load, and can be mounted on a joist without the need for a floor base plate. Can be installed on

[0008]

The present invention will be described below in detail with reference to examples. FIG.
1 shows an embodiment of the present invention, in which a soundproof floor panel 2 is shown.
Is formed by providing a plurality of parallel vibration absorbing grooves 1 at predetermined intervals of about 60 mm in the lower part of a plate material 8 formed of plywood having a thickness of about 9 to 10 mm. A surface plate 10 made of a plywood or the like having a thickness of about 2.5 mm is laminated and adhered on the upper surface of the plate material 8 through a cushion material 9 such as a rubber sheet. 11 is laminated and bonded. Further, a connecting male member 12 is provided on one of the opposite side end surfaces of the plate member 8.
On the other side end surface, a connecting female nut 13 is provided.

The sound-insulating floor panel A can be formed by laminating and bonding the sound-insulating floor panel 2 formed as described above on the substrate 3. The substrate 3 has a thickness of 12 to 1 mm.
It can be formed of a control panel plywood, particle board, medium-density fiberboard (MDF) or the like of about 5 mm. In addition, fitting male nuts 14 are provided on one of the opposite side end surfaces of the substrate 3.
On the other side end surface, fitting female nuts 15 are provided. Substrate 3 is formed in the same area dimensions as insulating floor panels 2 are so as to create a sound-insulating floor members A by product layer both as shown in Figure 1. In order to improve soundproofing performance,
It is preferable that the soundproof floor panel 2 is laminated and adhered on the substrate 3 via a cushion material 16 such as a rubber sheet, but of course, the present invention is not limited to this. Here, the upper surface of the substrate 3
So that the soundproof floor panel 2 is shifted
The edge of the substrate 3 on the side where the fitting male nut 14 is provided is prevented.
It protrudes about 10 to 50 mm from the side edge of the sound floor panel 2
I'm trying.

[0010] Thus sound-insulating floor members A that is created as described above, passes over the top of the joist 17 constituting the subfloor of the room of the house arranged plurality, fitting the substrate from the base upper surface of the case for Omi 14 The nail 18 can be fixed to the joist 17 by driving the nail 18 into the joist 17 through the hole 1. Since the soundproof floor panel 2 can be reinforced by the substrate 1 and can support a load, the joist 1 can be used without using a floor base plate.
The sound-insulating floor material A can be directly constructed on the floor 7 and can be firmly fixed to the joist 17 by nailing. Here, the base on the side where the fitting male nut 14 is provided
The edge of the plate 3 projects from the side edge of the soundproof floor panel 2
The nail 18 from the fitting male 14 of the substrate 3
The driving work is done without the soundproof floor panel 2 getting in the way.
Can handle and improve nailing workability
Things. The pair of adjacent soundproof floor members A is fitted with the fitting male nuts 14 provided on the substrate 1 of one soundproof floor member A with the female members 15 for fitting provided on the substrate 1 of the other soundproof floor member A. it is possible to connect by to case. In the adjacent soundproof floor material A, the soundproof floor panels 2 can also be connected to each other by fitting the connection male 12 and the connection female 13. The fitting male 14 and the fitting female 15 are fitted together, or the connecting male 1
In fitting the female nut 2 for connection with the female nut 13 for connection,
If necessary, an adhesive may be applied between the two.

As described above, since the soundproof flooring A can be directly mounted on the joist 17 without forming the floor slab on the joist 1, the soundproof floor can be formed. There is no danger that the soundproof floor material A mounted on the floor base plate will be lifted up or stomped on the steps between the floor base plates.

[0013]

As described above, according to the present invention, the soundproof floor panel formed by cutting and providing a plurality of vibration absorbing grooves on the lower surface is laminated and integrated on the substrate, so that the soundproof floor panel is reinforced by the substrate. It is capable of supporting a load, and can be constructed directly on a joist without the need for a floor substrate. In addition, the connecting male and female connector are provided on one end surface and the other end surface of the soundproof floor panel, respectively, and the fitting male connector and the fitting female connector are provided on one end surface and the other end surface of the board. When connecting the soundproof floor material, the soundproof floor panels are mated with the connecting male and female mating mats, and the boards are mated with the mating male and mating male mates, respectively, to form a double connection. It is possible to achieve high connection strength. In addition, a mating board is provided.
The girder ends do not protrude from the end of the acoustical floor panel.
The soundproof floor panels are integrated on the board
Then, nail the nails from the mating mats to fix the soundproof flooring.
When setting the nails, the work of driving the nails
Can be performed without distraction,
It is possible to enhance business performance.
