Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a floor panel that improves the sound insulation properties of an upper floor and is convenient to handle.

[Background technology]

In a building using the dry construction method, the floor panels that form the floor are, for example, as shown schematically in Figure 6.
Flooring material D and ceiling material E were attached to the top and bottom of the framework A, which was made up of frame materials arranged in a rectangular shape, with joist material B and edging material C placed over it. However, when installing such floor panels, although finishing materials are added to the flooring material D and ceiling material E, impact noise generated by the flooring material easily penetrates downward, resulting in poor sound insulation properties. It was hot.

Therefore, when such conventional floor panels are 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 into improving the sound insulation properties of floor panels, it was discovered that by increasing the weight of the floor panels by installing heavy sound insulation boards, the sound insulation properties could be improved to a considerable extent. At the same time, the present invention was completed by devising a convenient mounting structure for the sound insulation board.

[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 installed conveniently by using a receiving metal fitting.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 to 5, the floor panel 1 includes a framework 2 with joists 4 and edging materials 5 placed over it.
While the flooring material 6 is attached to the upper surface of the framework 2, a heavy sound insulating board 10 is installed between the shedding materials 5, 5 on the framework 2 using the brackets 9 arranged on the shedding materials 5. There is.

Narrow portions 32 are formed at both ends of the horizontal frame member 30, which are fitted into the grooves of the vertical frame member 29 and fixed by welding.

Note that the flange under the horizontal frame member 30 is raised upward between the outer edges of the flanges under the vertical frame members 29, 29, and a partition member 34 made of wood is fitted into the lower surface of the flange. A fixing ridge 35 is formed over its entire length. Note that the lower surface of the partition member 34 is flush with the lower surface of the framework 2.

A support frame member 37 is mounted on the lower flange of the vertical frame member 29 and has approximately the same width as the flange and is spaced apart from the upper flange. Attach the end of the wild edge material 5.

The joist material 4 is a wooden material with a vertically elongated rectangular cross section, and its both ends are fitted onto the upper surface of the support frame material 37, and a flange on the upper surface has the same thickness as the flange on the vertical frame material 29. By providing the cutout portion 39, the joist material 4 becomes flush with the upper surface of the framework 2.

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 on the upper end surface, and the edge material 5 has the protruding piece 43 fitted into the notched groove 41. By doing so, it is bridged between the vertical frame members 29, 29, and due to the spanning, its lower surface becomes flush with the lower surface of the framework 2.

Further, the receiving metal fittings 9 are attached to the field edge material 5 at appropriate pitches.

The receiving metal fitting 9 is a bent body of a steel plate, and in this example, a protrusion 14 having a V-shaped folded portion at the upper end is formed on both ends of a base piece 13 whose width exceeds the width of the field edge material 5.
14 have been erected. In addition, the receiving metal fitting 9 has a base piece 13 fixed between the edge material 5 with nails, screws, etc., and the protrusion 14 is located on the side surface of the edge material 5 and is spaced apart from the side surface. Start up.

The sound insulating board 10 is made of a material having a relatively high specific gravity compared to lightweight wood, such as a gypsum board, a concrete board, a metal board, a board made of a mixture of cement and a heat insulating material, or a board made of synthetic resin mixed with high-density granules. It consists of a plate-shaped body made of the same material.

In addition, in this embodiment, the sound insulating plate 10 includes three substrates 1.
It is a laminate of 0A, 10B, 10C, and the edge material 1
1 and 11 on both sides, and the base frame 12
is formed.

The edge material 11 is preferably a frame material such as a rubber material, a synthetic resin material, or a wooden material, which has excellent cushioning properties, can be nailed, and has the same height as the total thickness of the substrates 10A to 10C. Also, substrates 10A to 10C
The base frame is formed by forming a laminate in advance using an adhesive or the like, and then joining the edge material 11 and the sound insulating board 10 to each other using nails or adhesive, thereby forming an integral base frame. form 12. Also, edge material 1
1, by inserting a base frame 12 between the edge materials 5, 5, a continuous groove 15 is recessed at a position that matches the protrusion 14.

The lower surface of the base frame 12 is held flush with the framework 2 by fitting the protrusions 14 into the grooves 15 and installing it between the edge materials 5, 5. In addition, the base frame 12
is arranged not only between the field edge materials 5 and 5 but also between the field edge material 5 and the frame material 30.

Further, a ceiling material 7 fixed to the fence 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.

Note that various finishing materials are added to the flooring material 6 and 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 properties can be improved.
In addition, the floor panel 1, as shown in FIGS. 1 and 5,
By juxtaposing and spanning, it is possible to form an upper floor and a lower floor ceiling. In addition, the floor panel 1 has long and short sides along the outside wall of the house attached to the wall panel 21 on the floor below.

[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, heavy sound insulating boards are attached to the framework using metal fittings that attach to the field edge materials, which increases the weight and improves the sound insulation performance, resulting in lower noise levels on the floors. It is possible to reduce the transmission of noise to the downstairs due to vibrations and impacts caused when walking or walking, thereby improving the livability of the house. Furthermore, when the sound insulating board is placed within the framework, its thickness hardly changes compared to conventional floor panels, making it easy to install.

Moreover, the sound insulation board can be attached using a metal fitting, 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.
