DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration floor structure suitably used for a wooden house or the like.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional floor structure generally has a floor panel 3 in which a face material 2 is pasted on an upper surface of a core material 1 previously assembled in a square frame shape at a factory or the like. After laying, a ceiling material (not shown) such as a gypsum board is joined to the lower surface of the floor panel 3 on site.

[0003]

However, in such a floor structure, as shown in FIG. 4, when an impact from above is applied, each of the core members 1, 1 moves independently. Therefore, bending and vibration may occur.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an anti-vibration floor structure capable of obtaining a high anti-vibration effect against an impact on a floor.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a plurality of floor panels each having at least a quadrangular frame-like core material with a face material attached to an upper surface thereof, and between core material arranged parallel to one another in the panel, the core material and the
A blocking material attached in a direction orthogonal to the face material, and on the lower surface of the plurality of floor panels and on a position corresponding to the blocking material attachment position and an extension thereof, directly or through a ceiling material, the floor panels are joined together. It is characterized by comprising a band-shaped vibration-proof reinforcing plywood attached in parallel with the face material so as to be connected in a lateral direction .

[0006]

According to the vibration-insulating floor structure of the present invention, since the blocking members are attached between the core members, the core members are connected to each other by the blocking members, and individual movements are suppressed. Further, since the vibration-proof reinforcing plywood is provided below the blocking material, the action of suppressing the movement of the core material is synergistically enhanced. Therefore, in the vibration isolating floor structure, the amplitude is suppressed to be small with respect to the impact on the floor, and the impact is also transmitted in the lateral direction, whereby the vibration is dispersed and absorbed, and a high vibration isolating effect is obtained.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail. FIG.
FIG. 3 to FIG. 3 show one embodiment of the vibration isolating floor structure of the present invention. In the figure, reference numeral 10 denotes a floor panel. This floor panel 10 forms a frame 11 by assembling a vertical core material 11a and a horizontal core material 11b into a rectangular frame shape, and forms a vertical core material 1 in the center of the inside of the frame body.
A reinforcing core material 11c is provided so as to be parallel to 1a, and a face material 12 is attached to an upper surface of the frame body 11. The floor panels 10, 10 have vertical core members 11a, 11a.
Two or more bodies are juxtaposed and joined together in abutting state,
It is laid at a predetermined position such as a floor.

[0008] gap formed between the vertical core 11a and the reinforcing core 11c of the floor panel 10, Tateshinzai 11a Oyo
A blocking material 13 is disposed in a direction orthogonal to the surface material 12 and both ends thereof are a vertical core material 11a and a reinforcing core material 11c, respectively.
Attached to. In addition, this blocking material 13
Is joined to the lower surface of the face material 12 of the floor panel 10. In FIG. 3, the blocking material 13 is used for the floor panel 10.
Although it is attached to only one of the two gaps formed between the vertical core material 11a and the reinforcing core material 11c at substantially the center in the vertical direction, it may be attached to both of the two gaps, Also, it may be attached to other places in the vertical direction.

A ceiling member 14 such as a gypsum board is disposed on the lower surfaces of the floor panels 10, 10,... And is joined to the lower surfaces of the core members 11a and 11b and the reinforcing core member 11c.

On the lower surface of the ceiling member 14 and at a position corresponding to the mounting position of the blocking member 13 and on an extension thereof, a vibration-proof reinforcing plywood 15 is joined in parallel with the face member 12 . The anti-vibration reinforcing plywood 15 is a band-shaped plate body having a predetermined width, and is arranged so that the center in the width direction is placed on the mounting position of the blocking material 13.
Are extended in the lateral direction of the floor panels 10, 10,. The anti-vibration reinforcing plywood 15 is fixed by driving a screw nail 16 into the vertical core 11a and the reinforcing core 11c at a position corresponding to the vertical core 11a and the reinforcing core 11c of the floor panel 10. Furthermore, as shown in FIG. 2, a screw nail 17 may also be hit on the blocking material 13, whereby the anti-vibration reinforcing plywood 15 is formed.
Is more reliably fixed.

In order to obtain the vibration-isolated floor structure as described above, first, in a factory or the like, the vertical core material 11
The blocking material 13 is attached between the a and the reinforcing core material 11c. After laying the floor panel 10 on the site, a ceiling material (plaster board) 14 is stuck thereon, and a vibration-proof reinforcement plywood 15 is joined to a lower surface thereof and a position corresponding to a blocking material mounting position, and is screwed with a screw nail 16. Fix it.

In this vibration isolating floor structure, since the blocking material 13 is attached between the core material 11a and the reinforcing core material 11c, the core material 11a and the reinforcing core material 11c are separated from each other by the blocking material 13. Linked and individual movements are suppressed. Further, since the vibration-proof reinforcing plywood 15 is provided below the blocking material 13, the action of suppressing the movement of the core material 11a and the reinforcing core material 11c is further enhanced synergistically. Therefore, in the vibration-isolated floor structure, the amplitude on the floor is suppressed to a small value, and the vibration is dispersed and absorbed in the lateral direction as well. Therefore, a high anti-vibration effect can be obtained.

It should be noted that the present invention is not limited to the above-described embodiment, and it is of course possible to add various changes in specific components and the like without departing from the scope of the present invention. For example, a plurality of reinforcing core members 11c of the floor panel 10 may be provided instead of one. In this case, the mounting position and the number of the blocking members 13 may be appropriately changed. Further, in the above-described embodiment, the vibration-proof reinforcing plywood 15 is a single band-shaped plate, but a plurality of plates may be joined and used in the middle. And the vicinity of the end of each vibration-proof reinforcement plywood is fixed to the blocking material 13 with the screw nail 17. In the above-described embodiment, the ceiling material (gypsum board) 14 is joined to the lower surface of the floor panel 10. However, in some cases, this gypsum board is omitted, and the vibration-proof reinforcement plywood 1 is directly attached to the lower surface of the floor panel 10.
5 can be attached.

[0014]

As described above, according to the anti-vibration floor structure of the present invention, the blocking material and the anti-vibration reinforcing plywood provide
Since movement between floor panels, especially between the core materials of the floor panels, is suppressed, vibration can be dispersed and absorbed, and a high vibration-proof effect can be obtained.
