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 forming the floor are, for example, as shown schematically in Figure 5.
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 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 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]

The present invention improves the sound insulation performance by installing a heavy sound insulation board on the frame, and solves the above problems. The aim is to provide a floor panel that also improves the efficiency of installation work.

[Disclosure of invention]

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

In FIGS. 1 and 2, the floor panel 1 is constructed by laying joists 4 and edging materials 5 inside the framework 2, and
A flooring material 6 is attached to the upper surface of the framework 2, and a ceiling material 7 is attached to the lower surface of the framework 2, while a heavy sound insulating board 1 is installed above the ceiling material 7 using a support fitting 11 attached to the edging material 5.
0 is set.

In addition, as schematically shown in FIG. 4, the floor panel 1 includes, for example, a corner fitting 22 attached to the upper end of the wall panel 21 on the floor below, a middle fitting 23, and a connecting fitting 24 connecting the wall panels 21. By bolting the sides together, juxtaposing them, and constructing them, an upper floor and a lower floor ceiling are formed. In addition, each of the metal fittings 22 to 24 also connects the wall panels 26 on the floor, and also connects the floor panels 1
It is also possible to span the structure on so-called columns, beams, etc.

The framework 2 is made by joining long vertical frame members 29, 29 and horizontal frame members 30, 30 made of channel steel in a rectangular shape with each groove facing inward, and when joining,
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.

Further, a frame member 31 made of H-beams made of interlocked H-beams is bridged to the frame 2 with its upper and lower surfaces aligned.

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.

At the lower flange of the vertical frame member 29, there is a support frame member 37 which has approximately the same width as the flange and is separated from the upper flange. The support frame members 37 are used to attach the end portions of the joists 4 and edging members 5 to each other.

The joist material 4 is a wooden material with a vertically elongated rectangular cross section, and its both ends are placed in contact with the upper surface of the support frame material 37, and the upper surface has a flange of the same thickness as the upper surface of 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, 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 edge material 5.

The field edge material 5 is made of a wooden material having a protruding piece 43 at the same height as the notch groove 41 on the upper end surface, and the field edge material 5 has the projecting piece 43 fitted into the notched groove 41. By doing so, the field edge material 5 is attached to the horizontal frame material 3.
0 and 30, and due to the spanning, its lower surface is flush with the lower surface of the framework 2.

The sound insulation 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 material.

In this embodiment, the sound insulating board 10 is made of a laminated material to which three substrates 10A, 10B, and 10C are attached in advance, and between the edge materials 5 and 5, and between the edge materials 5 and the frame material 30. A material having a width that can substantially cover the space between the frame material 5 and the web of the frame material 31 inside is prepared in advance.

Further, the side edge of the sound insulating board 10 facing each of the fence materials 5 is supported using the support metal fittings 11, and the side edge facing the frame material 30 uses another support metal fitting 12. Note that the side edge facing the frame material 31 inside is
Attach to the top surface of the flange below.

The supporting metal fittings 11 have side pieces 4 along the sides of the field edge material 5 on both side edges of the upper piece 45 that straddles the upper surface of the field edge material 5.
6 and 46, and a support piece 47 whose lower surface is flush with the lower surface of the field edge material 5 is provided at the lower end of the support piece 47 projecting outward at right angles to the field edge material 5, forming a hat shape. , are arranged side by side on the field edge material 5 at appropriate intervals.

In addition, the support fitting 12 has a side piece 50 on the upper piece 49 that contacts the upper surface of the flange under the horizontal frame member 30, and a support piece 51 whose lower surface is flush with the lower surface of the frame 2 at a right angle to the lower end thereof. The supporting metal fittings 12
has its side piece 50 fixed to the partition member 34 by nailing or the like, and is spaced apart from the support fitting 11 in a straight line.

Therefore, the sound insulating plate 10 has the support pieces 47, 51
The side ends are respectively placed on the lower flange of the inner frame member 31 as described above.

Furthermore, the flooring material 6 is attached to the upper surface of the framework 2, and the ceiling material 7 is attached to the lower surface of the framework 2 to complete the floor panel 1, and therefore the sound insulating board 10 is placed above the ceiling material 7.

The floor panel 1 is spanned using the metal fittings 22 to 24 shown in FIG. 4 to form an upper floor and a 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.

FIG. 3 shows another embodiment using an L-shaped support fitting 11, in which the side piece 46 of the support fitting 11 is fixed to the side surface of the field edge material 5 by nailing or the like, and the side piece 46 is fixed to the side surface of the field edge material 5. The sound insulating plate 10 can be placed on the support piece 47 which is perpendicular to and horizontal to the above.

In this embodiment, the sound insulating board 10 is a thick plate-like integral molded product, and the lower end thereof is provided with an L-shaped notch 54 on the side edge facing the frame material 30. The section 54 is supported by fitting the flange under the frame member 30 and the standoff member 34 .

[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. While placing the materials, above the ceiling materials,
Since the heavy sound insulating board is attached to the frame using support metal fittings that attach to the roof edge material, its weight is increased and the sound insulating performance is improved.As a result, noise on the floor or when walking is It can reduce the transmission of noise caused by vibrations and shocks to the lower floors, 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.

In addition, since the sound insulation board is attached using the support metal fittings, the sound insulation board is supported reliably and the installation work is easy. Because it is placed on a support piece, there is a gap between the sound insulation board and the ceiling board that is equal to the thickness of the support piece. can be absorbed by the gap, and deformation of the ceiling board can be effectively absorbed.

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.
