Description

Description: TECHNICAL FIELD The present invention relates to a floor panel capable of improving sound insulation of an upper floor.

[Background technology]

In a building of a dry construction method, a floor panel forming the floor is constructed by, for example, as schematically shown in FIG. In addition,
In addition, a floor base material D and a ceiling base material E were attached to the lower surface. However, in such a floor panel, although flooring materials such as finishing floorboards are added to the flooring material D and the ceiling material E, respectively, at the time of installation, the impact sound generated by the flooring material is easily lowered. It was transparent and inferior in sound insulation.

Therefore, when such a conventional floor panel is used as an upstairs floor, noise from conversations and audio equipment on the floor passes downstairs, and noise due to shock, vibration, etc., such as walking or jumping upstairs. Was transmitted to the downstairs without being absorbed much, hindering the habitability of the house.

Therefore, as a result of repeated studies on the improvement of the sound insulation of the floor panel, it was found that the sound insulation can be improved to a considerable extent by increasing the weight of the floor panel.

However, in the upper room, there are a Western room in which a floor board or the like is laid on a floor base material, and a Japanese room in which a tatami mat is laid, and the tatami mat is excellent in sound absorption. Therefore, it is preferable to arrange the sound insulation plate in contact with the floor material in a Western-style room, and in the Japanese room, it is desirable to arrange the sound insulation plate on the lower surface as a base material for mounting the ceiling board. The mounting position changes.
However, preparing two types of floor panels with different sound insulation plate positions complicates production and inventory control.

[Object of the Invention]

An object of the present invention is to provide a floor panel capable of changing the mounting position of the sound insulation plate and solving the above-mentioned problems.

It is laid between 37. Further, the upper surface of the joist 4 is flush with the framework 2 by providing a notch 38 having the thickness of the flange on the vertical frame member 29.

On the upper surface of the support frame member 37, a U-shaped notch groove 41 is provided in the mounting position of the field edge member 5 in a direction transverse to the support frame member 37. The notch groove 41 is set to have the same width as the field edge material 5.

The field edge member 5 is provided with a protruding piece 43 having the same height as the cutout groove 41 on the upper end surface and is made of a nailable wooden material. Further, the field edge material 5 is bridged between the vertical frame members 29, 29 by fitting the projecting piece 43 into the notch groove 41, and the lower surface of the field edge material 5 is the lower surface of the framework 2. It will be the same.

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

Further, the sound insulation plate 10 is composed of three substrates 10A and 1A in this embodiment.
0B and 10C are placed on top of each other, and substrates 10A, 10B and 1
0C is formed so that it can fit into the space between the flange of the horizontal frame member 30 and the joist 4 and between the joists 4 and 4 on the upper surface of the framework 2.

In the present example, the receiving metal fitting 3 is a reverse-hat-shaped steel plate in which a receiving piece 13 is provided on both sides of a base piece 11 having a length exceeding the width dimension of the joist 4 and is extended to the outside via a rising piece 12. It consists of a folded body. A through hole is provided in the center of the base piece 11, and the screw shaft 1 supported above and below the side hole 14 of the joist 4 is provided in the through hole.
5 penetrates, and the receiving metal fitting 3 is fixed so that the vertical position can be adjusted using a nut screwed to the screw shaft 15 above and below the base piece 11.

The receiving metal fitting 3 is fixed by aligning the receiving piece 13 such that its upper surface is lower than the upper surface of the frame 2 by the total thickness of the substrates 10A to 10C.

Further, a receiving metal fitting 17 having a receiving piece 16 that extends inward and at the same height as the receiving piece 13 is also fixed to the horizontal frame member 30.

Therefore, the sound insulation plate 10 is the receiving piece 1 of the joists 4 and 4 facing each other.
