Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a floor panel that can improve the sound insulation of an upper floor.

[Background technology]

In a building using the dry construction method, the floor panels that form the floor are, for example, as schematically shown in Figure 4.
Flooring material D and ceiling material E were attached to the upper and lower surfaces of the framework A, which had frame materials arranged in a rectangular shape, with joist materials B and edging materials C spanning over it. However, when installing such a floor panel, although finishing materials are added to the floor material D and ceiling material E, impact noise generated by the floor material easily penetrates downward, resulting in poor sound insulation properties. It was hot.

Therefore, when such a conventional floor panel is used as an upper floor, the sounds of conversations and audio equipment on the floor pass through to the downstairs, and also the noise caused by shocks and vibrations caused by walking and jumping on the floor. Noise was transmitted downstairs without being absorbed to a large extent, impeding the livability of the house.

Therefore, as a result of repeated research on improving the sound insulation properties of floor panels, we discovered that by increasing the weight of the floor panels, the sound insulation properties could be improved to a considerable extent, and we completed the present invention. be.

[Purpose of invention]

This invention improves sound insulation performance by installing heavy sound insulation boards within the framework of the floor panel, and
The object of the present invention is to provide a floor panel in which the sound insulation board can be easily installed by forming the sound insulation board as a base material using edge material in advance.

At the lower flange of the vertical frame member 29, a support frame member 37 having approximately the same width as the flange and separated from the upper flange is provided, which is substantially continuous between the horizontal frame member 30 and the inner frame member 31. The supporting frame material 37 is used to attach the ends of the joist material 4 and the edge material 5.

The joist material 4 is a wooden material having a longitudinally elongated rectangular surface, and is constructed so that its both ends are in contact with the upper surface of the support frame material 37, and a flange of the same thickness as the upper surface of the vertical frame material 29 is provided on the upper surface. By providing the cutout portion 39, the joist material 4 becomes flush with the upper surface of the framework 2. Further, in this example, three joists 4 are arranged so as to divide the space between the horizontal frame material 30 and the inner frame material 31 into approximately four equal parts.

Further, on the upper surface of the support frame material 37, there is a U-shaped notch groove 41 located approximately in the center of the joists 4, 4.
is recessed in a direction transverse to the support frame member 37.
Note that the notch groove 41 is set to have the same width as the field edge material 5.

The edge material 5 is made of a wood material and has a protruding piece 43 at the same height as the notched groove 41 at the upper part of the end surface, and the edge material 5 has a protruding piece 43 that is fitted into the notched groove 41. By attaching the frame material 5 to the horizontal frame material 3,
0 and 30, and the lower surface thereof is aligned with the lower surface of the framework 2 due to the spanning.

The sound insulation board 10 is a gypsum board, a concrete board, a metal board, or a mixed board of cement and heat insulating material.
Alternatively, it is made of a plate-like material made of a material that has a relatively higher specific gravity than lightweight wood, such as a mixture of synthetic resin and high-density granules.

In this embodiment, the sound insulating board 10 is a laminate of three substrates 10A, 10B, and 10C, and as described above, both ends are supported by the edge materials 11, 11 to form the base frame 12. ing.

The edge material 11 is made of wood or the like and can be nailed to the substrate 1.
A frame material having the same height as the total thickness of 0A to 10C is used, and the substrate 10A,
It forms an L-shape with L-shaped notches 45, 45 having the same height as 10B. The substrates 10A and 10B are fitted into the cutouts 44 and 45, and the substrate 10C is
The substrates 10A to 10C can be fitted between the protruding portions 46 below the cutout portions 45, and form a laminate in which the substrates 10A to 10C are laminated in advance using an adhesive or the like. Note that the edge material 11 and the sound insulating board 10 are joined to each other using nails or adhesive to form the integral base frame 12. In addition, the edge material 11 can also be formed as a rectangular frame surrounding the sound insulation board 10, and in this case, the sound insulation board 1

Further, a ceiling material 7 fixed to the edging material 5 and the partition material 34 is attached to the lower surface thereof, and a floor material 6 is attached to the upper surface of the framework 2.

The floor panel 1 is spanned using the metal fittings 22 to 24 shown in FIG. 3 to form the upper floor and the lower floor ceiling as described above. Furthermore, flooring material 6,
Various finishing materials are added to the ceiling material 7 as necessary.

Therefore, since the floor panel 1 includes the heavy sound insulation board 10, its weight can be increased and the sound insulation performance can be improved.

[Effect of idea]

In this way, the floor panel of the present invention has frame materials arranged in a rectangular shape, with joists placed above the frame and edging materials placed below. At the same time, a heavy sound insulating board made of edge material is attached to the frame as a base frame, which increases the weight and improves the sound insulation performance.As a result, the noise on the floor, Also, it is possible to reduce the transmission of noise caused by vibrations and impacts caused by walking to the lower floors, thereby improving the livability of the house. Furthermore, since the sound insulation board is placed within the framework, its thickness hardly changes compared to conventional floor panels, making it easier to install.

Further, since the sound insulation board is formed in advance into a base frame shape using edge material, it can be easily fixed to the field edge material by nailing or the like, and the installation work of the sound insulation board can be streamlined.

In addition, the conventional product that used particle board with a thickness of 15 mm as the floor material 6 and plasterboard with a thickness of 9 mm as the ceiling material 7 had a sound insulation grade of about L-75, which is the transmitted decibel at 500 Hz. Compared to that, the product of this example had a grade of about L-65 to L-70.
