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 method 1 method, the floor panels that form the floor are, for example, as shown schematically in Figure 7 (i.e., a frame A with frame materials arranged in a rectangular shape, a joist material B and a edging material C). After crossing the bridge,
Moreover, floor underlayment material D1 and ceiling underlayment material E were attached to the lower surface. However, when installing such floor panels, it is necessary to use the subfloor material.

Although flooring materials such as finishing floorboards are attached to each ceiling base material, impact noise generated by the flooring material easily penetrates downward, resulting in poor sound insulation.

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 the noise from shocks and vibrations caused by walking and jumping on the floor. is transmitted downstairs without being absorbed much,
This hindered the livability of the house.

Therefore, as a result of repeated research into improving the sound insulation properties of floor panels, it has been found that increasing the weight of the floor panels can improve the sound insulation properties to a considerable extent.

[Purpose of the invention]

The present invention aims to provide a floor panel that can improve the sound insulation properties of an upper floor.

[Disclosure of the invention]

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

In FIGS. 1 to 6, the floor panel 1 includes a joist 4 placed over the inside of the framework 2, a subfloor material 8 provided on the upper surface of the framework 2, and a pre-rise subfloor material 8 placed inside the framework 2. A heavy sound insulating board 10 is placed in contact with the lower surface, and in this embodiment, the heavy sound insulating board 10 is placed flush with the top surface of the framework 2 using the metal holder 3 provided on the joist 4. By supporting the sound insulating plate 10, the sound insulating plate 10 is brought into contact with the lower surface of the subfloor material 8, and the sound insulating plate 10 can also be attached to the lower surface of the framework 2.

Moreover, the floor panels 1 form an upper floor part and a lower floor ceiling part by juxtaposing and constructing.

The framework 2 is a long vertical frame member 29.2 made of groove-shaped sea bream.
9. Horizontal frame members 30. 30 are joined in a rectangular shape with each groove facing inward, and when joining, narrow portions 32 are formed at both ends of the horizontal frame members 30, and vertical frame members 29 It fits into the groove and is fixed by welding.

Note that the vertical frame member 29. is attached to the flange below the horizontal frame member 30.
Between the outer edges of the flanges below the flange 29, a raised portion 35 is formed over the entire length of the lower surface of the raised portion 35 into which a partition member 34 made of wood is inserted and fixed. Note that the lower surface of the partition member 34 is aligned with the lower surface of the framework 2.

A support frame member 37 is provided on the lower flange of the vertical frame member 29, approximately halfway between the vertical frame member 29 and separated from the upper flange.
The support frame members 37 are used to attach the end portions of the edging material 5 together with the joists 4.

The joist material 4 is a wooden material having a longitudinally elongated rectangular cross section, and its both ends are supported by fitting the upper part of the support frame material 37 into notches 39 provided on the lower surface.
It spans 7 spaces. Also, the upper surface of the joist material 4 is the vertical frame material 2
By providing a notch 38 having the thickness of the upper flange 9, the upper surface is made flush with the framework 2.

Further, on the upper surface of the support frame material 37, a U-shaped notch groove 41 is recessed in a direction transverse to the support frame material 37, located approximately at the center of the joist material 4. Note that the notch groove 41 is
and set in between.

The edge material 5 is provided with a protruding piece 43 having the same height as the notched groove 41 on the upper end surface, and is made of a nailable wooden material. The edge material 5 is spanned between the vertical frame members 29 and 29 by fitting the projecting piece 43 into the notch groove 41, and the lower surface of the bunraku is connected to the lower surface of the framework 2 by means of a bridge. Be in order.

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

In addition, in this embodiment, the sound insulating plate 10 includes three substrates 10A, I
It consists of a stacked body in which OB and IOC are placed one on top of the other, and the board 10A,
The IOB and IOC are formed to a size that allows them to fit into the space on the upper surface of the framework 2 between the flanges of the horizontal frame members 30 and the joists 4 and between the joists 4 and 4, thereby forming the frames 1&lI2.
9 is placed inside.

In this example, the receiving fitting 3 is an inverted hat-shaped steel plate provided with receiving pieces 13 extending outward via upright pieces 12 on both sides of a base piece 11 whose length exceeds the width of the joist 4. Consists of a bent body. A through hole is provided in the center of the x base piece 11, and the through hole has a screw shaft 15 supported above and below the side hole 14 of the joist material 4.
passes through the base piece 11, and the receiving metal fitting 3 is fixed so as to be vertically adjustable using nuts screwed onto the screw shaft 15 above and below the base piece 11.

Note that the receiving metal fitting 3 adjusts and fixes the receiving piece 13 at a height such that its upper surface is at a position lower than the upper surface of the framework 2 by the total thickness of the substrates 10A to IOC.

Further, a receiving metal fitting 17 having a receiving piece 16 protruding inside and at the same height as the receiving piece 13 is fixed to the horizontal frame member 30 as well.

Therefore, the sound insulating board 10 is formed by supporting pieces 13 of the joists 4.4 facing each other.
．． 13. The sound insulation board is bridged by supporting the side edges of the joist 4 and the support pieces 16 of the horizontal frame material 30, and by adjusting the height of the support fitting 3 that supports the sound insulation material 10 by the support pieces 13. It is obvious that the upper surface of the frame 1M2 can come into contact with the lower surface of the underfloor material 8 by aligning it with the upper surface of the frame 1M2.

Moreover, a floor body is formed by disposing a flooring material 6 for forming a floor of a Western-style room or a hallway on the floor base material 8 on the upper surface of the framework 2. Incidentally, on the lower surface of the framework 2, a ceiling material 7 that is nailed to the edging material 5 and the partition material 34 is attached to the base material.

Therefore, the sound insulating board 10 substantially shields the framework 2 and is in contact with the floor material 6 via the subfloor material 8.

When using the floor panel 1 for a Japanese-style room, loosen the nuts, lower the bracket 3, and remove the bracket 13 if necessary.
The support of the sound insulating plate 10 is released by accommodating the sound insulating plate 10 in a side hole or the like. Further, the taken out sound insulating board 10 is attached to the lower surface of the framework 2 as shown in FIG. 5, and used as a base for attaching the ceiling board 7. As the sound insulating board 10, one of the boards 10A to IOC may be used, or all of them may be attached.

The floor panel 1 can be used as shown in FIGS. 1 and 6 (by juxtaposing or spanning the floor, it is possible to form an upper floor and a lower floor ceiling. Also, the floor panel 1 can be placed along the outside wall of the house. The long side and the short side are connected to the corner fitting 22 at the upper end of the downstairs wall panel 21,
The inner fitting 23 and the wall panel 21 are fixed by being bolted to each side piece 25 of a connecting fitting 24 that connects the wall panel 21 with a gap therebetween. Fittings 22, 23, 24 also support the upper wall panel 26 at its lower end. Moreover, the indoor side part can be bridged by bolting the short side to the beam material 27 and the long side to the fitting 28. Note that a packing 20 is interposed between the long sides of the floor panel 1 to which the inner metal fittings 23 are connected.

〔Effect of the invention〕

In this way, the floor panel of the present invention comes into contact with the lower surface of the flooring material! By providing an i-quality sound insulating board, noise and vibrations generated on the floor are prevented from permeating and being transmitted to the downstairs, improving the livability of the downstairs.

In addition, a conventional product that uses a 15cm thick vertical board as the flooring material 8 and a 9cm thick gypsum board as the ceiling material 7 has a sound insulation grade of about L-75 in terms of transmitted decibels at 500Hz. Compared to this, the product of this example had a grade of about 165 to 70.
