Abstract

(57) [Abstract] [Purpose] The present invention aims at a floor material for a soundproof room capable of improving the horizontal strength and the earthquake resistance of a sound insulation wall. [Structure] The floor material G is formed in a laminated structure in which a first plywood 3, a plasterboard 4 and a second plywood 6 are arranged in this order under the surface floor material 2, and the plasterboard 4 and the second plywood 6 are formed.
A metal plate 5 for strengthening the screw holding force is sandwiched between
A screw 7 is penetrated and fixed from the sound insulation wall 1 side to the metal plate 5.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a floor material for a soundproof room for improving the earthquake resistance of a sound insulation wall used in the soundproof room.

[0002]

[Prior Art]

 As shown in FIGS. 2 to 3, the conventional soundproof room floor material G has a laminated structure of flooring (15t) 2, plywood (9t) 3, plasterboard (12t) 4, and plywood (9t) 6. After the sound insulation wall 1 is placed on the floor material G, the frame 11 is fixed to the floor material G with screws 7 to fix the sound insulation wall 1.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, since the holding force of the screw between the sound insulation wall and the floor material is determined by the plywood of the floor material, the horizontal resistance R of the sound insulation wall is limited.

Therefore, the present invention has been devised in view of the problems of the above-mentioned conventional techniques, and an object thereof is to provide a floor material for a soundproof room capable of improving the horizontal resistance and the earthquake resistance of the sound insulation wall.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in a floor material for a soundproof room according to the present invention, the floor material is formed into a laminated structure in which a first plywood, a plasterboard and a second plywood are arranged in this order under a surface floor material. Between the plaster board and the second plywood, a metal plate for strengthening the screw holding force is sandwiched, and the screw is penetrated and fixed from the sound insulation wall side to the metal plate.

[0006]

[Action]

 When setting the floor material, place the first plywood, plasterboard, and second plywood in this order under the surface floor material, and insert a 0.5t metal plate between the plasterboard and the second plywood from the sound insulation wall side. The screws penetrate the metal plate of the floor material and fix it to improve the horizontal strength and earthquake resistance of the sound insulation wall.

[0007]

【Example】

 An example will be described with reference to FIG. It should be noted that part of the codes uses codes common to the codes used in the conventional technique.

In the sound insulation wall 1, a sound insulation material 12 is attached inside a frame member 11, and a screw hole 13 is formed in the frame member 11.

The floor material G is arranged under a surface floor material (flooring) 2 having a strength of about 15 tons, in the order of a first plywood 3 of about 9 t, a plasterboard 4 of about 12 t, and a second plywood 6 of about 9 t. A metal plate 5 having a laminated structure is sandwiched between the plasterboard 4 and the second plywood 6 for strengthening the screw 7 holding force.

The metal plate 5 is a thin iron plate through which the screw 7 can easily penetrate, and the metal plate 5 has a strength of about 0.5 t.

Further, the metal plate 5 can be installed only at a lower position of the screw 7 fixing portion of the sound insulation wall 1.

The screw 7 has a length that penetrates from the screw hole 13 of the frame member 11 to the metal plate 5 of the floor material G. By fixing the screw 7, the horizontal resistance of the sound insulation wall 1 is improved and the seismic resistance is improved. ing.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. A. When setting the floor material, a metal plate is sandwiched between the plasterboard and the second plywood on the lower side of the floor material, and the screw penetrates from the sound insulation wall side to the metal plate of the floor material. It is possible to improve the seismic resistance by, for example, at least 6 times or more compared with the conventional case.

B. Since the metal plate is thin and the screws can be easily penetrated, workability is good, and if the metal plate is set only below the screw stop of the sound insulation wall, the cost increase can be minimized.
