[0002]

2. Description of the Related Art In a building constructed by a dry construction method, a floor panel forming a floor is constructed by surrounding a frame a having a rectangular frame material with a joist material b and a field material, as schematically shown in FIG. c and the floor base plate d and the ceiling base plate e are additionally provided on the lower surface thereof. Also, when using such a floor panel as an upstairs floor, in order to prevent conversations on the upstairs and sounds of audio equipment, etc. from being transmitted downstairs,
On the floor panel, a heavy sound insulating plate f is arranged in the peripheral frame a. Conventionally, such a sound insulating plate f has been fixed to the lower surface of the floor base plate d by nailing or the like, and the sound insulating plate f may be attached to the joist material b.
By nailing the receiving material g that receives the lower surface, the relatively heavy sound insulating plate f is prevented from falling.

[0003]

However, in such a conventional one, since the sound insulating plate f is fixed to the floor base plate d by vertically inserting a nail or the like from below,
The joining strength of the heavy sound insulation plate f to the floor base plate d is inferior, which causes quality defects such as bending of the sound insulation plate f, and it is necessary to prepare a receiving material g for preventing the sound insulation plate f from falling. Increase the production cost. In addition, there is a problem to be solved such that the work of nailing the receiving material g to the joist material b is troublesome, the number of construction steps is increased, and the productivity is poor.

The present invention is based on the fact that the sound insulating plate is fixed to the floor base plate by obliquely inserting the drive member of the fixing bracket from below the sound insulation plate and bending the drive piece on the upper surface of the floor base plate. As a result, it is an object of the present invention to provide a floor panel that can reduce the number of member types, reduce the production cost and the number of construction steps, and increase the bonding strength of the sound insulation plate to the floor base plate.

[0005]

In order to achieve the above object, the floor panel of the present invention has a peripheral frame in which frame members are joined in a rectangular shape, and a joist member having the upper surface aligned with the peripheral frame. On the lower surface of the floor base plate arranged on the upper surface of the frame, a heavy sound insulation plate arranged in the space formed by the surrounding frame and the joist, is formed into a taper shape having driving pieces parallel to both ends of the base piece, and of the sound insulation plate. While the driving piece is obliquely driven from below and until the base piece comes into contact with the lower surface of the sound insulating plate, the driving piece is fixed using a fixing metal fitting that is bent on the upper surface of the floor base plate,
A diagonal notch is provided on the tip of the driving piece of the fixing member and on the surface that makes an acute angle with the sound insulation plate when the fixing piece is driven obliquely.

[0006]

[Operation] By inserting a heavy sound insulation plate, a tape-like fixing metal fitting having driving pieces parallel to both ends of the base piece is driven obliquely from below the sound insulation plate and until the base piece abuts the bottom surface of the sound insulation plate. Stick to the floor board. Further, when the fixing member is driven, the driving piece is bent on the upper surface of the floor base plate. In this way, the fixing bracket is inserted diagonally and with the base piece in contact with the lower surface of the sound insulation plate, and the driving piece is bent, so that the sound insulation plate can be firmly attached to the floor base plate, and as a result, the joint strength can be increased.
It is possible to prevent quality defects such as bending of the sound insulating plate from occurring, and it is possible to omit a member for preventing the sound insulating plate from falling, which can reduce the production cost and the number of construction steps.

Further, such a fitting of the fixing member can be easily carried out by using an appropriate device, the sound insulation plate can be automatically attached, and it is also useful for improving the productivity.

In addition, since the oblique notch is provided on the tip of the driving piece and on the surface which makes an acute angle with the sound insulating plate when it is driven obliquely, the driving piece can be smoothly bent and the driving work is facilitated. ..

The lower flange of the horizontal frame member 12 is bulged upward between the outer edges of the lower flanges of the vertical frame members 11 and 11, and a separating member 21 made of wood material is provided on the lower surface thereof. A ridge 22 for fitting and fixing is formed over its entire length. The lower surface of the separating member 21 is aligned with the lower surface of the peripheral frame 2.

On the lower flange of the vertical frame member 11, a supporting frame member 25 having substantially the same width as the flange and having a gap from the upper flange is placed almost continuously, and the supporting frame member 25 is used. The end of the edge material 26 is attached together with the joist material 3.

It is bridged between the support frame members 25. Further, the upper surface of the joist 3 is flush with the surrounding frame 2 by providing a notch 30 having the thickness of the flange on the vertical frame 11. On the upper surface of the supporting frame member 25, a U-shaped notch groove 32 is formed at a position approximately at the center of the joist member 3 in a direction crossing the supporting frame member 25. The cutout groove 32 is set to have the same width as the field edge material 26.

The field edge member 26 is provided with a projecting piece 33 having the same height as the cutout groove 32 on the upper end surface and is made of a nailable wood material. In addition, the field edge material 26,
By fitting in the notch groove 32, the vertical frame member 11,

The sound insulation plate 6 is a gypsum board, a concrete board, a metal plate, or a mixed plate of cement and a heat insulating material,
Alternatively, it is composed of a plate-like body made of a material having a relatively large specific gravity as compared with lightweight wood, such as a synthetic resin mixed with a high-density granular material.

In the present embodiment, the sound insulation plate 6 is composed of a stack of two substrates 6A and 6B placed one on top of the other.
The inside of the peripheral frame 2 is formed by forming the space between the flange on the horizontal frame member 12 and the joist 3 and between the joists 3 and 3 so that the space S on the upper surface of the perimeter frame 2 can be fitted. Are distributed to.

As shown in FIG. 6, in this embodiment, the fixing metal fitting 7 is a tape-shaped metal fitting having driving pieces 10 and 10 having a rectangular cross section parallel to both ends of a base piece 9 having a rectangular cross section. The sound insulation plate 6 and the floor base plate 5 are fixed to each other by inserting the sound insulation plate 6 from below.

The fixing metal fitting 7 is driven into the sound insulation plate 6 by the method described below. That is, in this example, as shown in FIG.
As shown in FIG. 5, the floor base plate 5 is placed on a base 35 having a horizontal upper surface, the sound insulating plate 6 is placed on the upper surface and the space S, and the upper surface of the sound insulating plate 6 and the vicinity of both ends thereof are arranged. The sound insulation plate 6 is firmly and temporarily fixed to the floor base plate 5 by being pressed downward by the pressing tool 36. As the pressing tool 36, a horizontally elongated rectangular metal body that moves up and down by a hydraulic cylinder is used.

On the sound insulation plate 6 temporarily fixed on the base 35 and the floor base plate 5, the driving pieces 10 and 10 of the fixing metal fitting 7 are placed obliquely above the sound insulation plate 6 with the base piece 9 facing upward. And is injected by an appropriate press-fitting device. The fixing metal fitting 7 is driven until the base piece 9 comes into contact with the upper surface of the sound insulation plate 6, whereby the tip of the linear driving piece 10 shown by the one-dot chain line in FIG. It is bent upward by the base 35.

The tip of the driving piece 10 is on a surface F facing the horizontal plane C on which the sound insulating plate 6 is placed when the fixing metal fitting 7 is obliquely driven, that is, a surface F forming an acute angle with the sound insulating plate 6.
A notch 10A is provided diagonally upward. Thereby, the bending of the driving piece 10 accompanying the driving of the fixing member 7 can be surely and easily performed. The notch 10A can be formed by forming the tip of the driving piece 10 into a triangular shape as shown in FIG. 6, but as shown in FIG. 7, only the notch 10B can be formed into a trapezoidal shape. Good. Further, the fixing member 7 may be formed by bending a relatively long cylindrical body having a circular cross section to form the base piece and the driving piece, respectively. In this case, the face F provided with the cutout portion has an elliptical shape. Become.

Further, it is desirable that the angle α formed by the driving piece 10 of the fixing member 7 and the perpendicular line k of the base 35, that is, the driving angle of the fixing member 7 is set to 20 ° or more and 50 ° or less. If the angle α is less than 20 °, the joint strength between the sound insulation plate 6 and the floor base plate 5 cannot be sufficiently obtained, and the driving piece 10 is difficult to bend. If the angle α is larger than 50 °, the sound insulating plate 6 may be cracked at the time of driving. Therefore, the angle α is 20 ° or more and 50 ° or less, more preferably 30 ° or more and 45 ° or less. Set to.

In the fixing metal fitting 7 thus inserted, the base piece 9 is in contact with the lower surface of the sound insulation plate 6 (the upper surface at the time of insertion) diagonally, and the insertion piece 10 is bent. The sound insulation plate 6 is firmly attached to the floor base plate 5 as compared with the joining by the nails of the
Can be fixed to. Moreover, since the fixing metal 7 has a strong joining force, the number of driving can be reduced, and the production cost can be reduced. Further, such driving of the fixture 7 can be automated by an appropriate device, which is also useful for improving productivity.

In the present embodiment, as shown by the broken line in FIG. 1, the fixing metal fittings 7 are driven in parallel to the vertical frame member 11 with the driving directions opposite to each other. Thereby, the sound insulation plate 6 can be more firmly fixed to the floor base plate 5. Further, as shown by a broken line in FIG. 8, even if the fixing metal fittings 7 are driven in parallel with the horizontal frame material 12 and the fixing metal fittings 7 ... Arranged in the extending direction of the vertical frame material 11 are made alternating with each other. The same effect can be obtained.

In this way, when the fixing members 7 are driven with the driving directions crossing each other, a sufficiently high bonding strength can be obtained even if the bending of the driving piece 10 is omitted.

The floor base plate 5 to which the sound insulating plate 6 is fixed is attached to the upper surface of the frame 4 with the sound insulating plate 6 facing downward and the joist 3 being loosely fitted between the sound insulating plates 6 and 6 adjacent to each other. At the same time, the floor material is formed on the floor base plate 5 by arranging the floor material 40 for forming the upper floor. On the lower surface of the frame 4, a field member 26 and a ceiling member 41 that is nailed to the separating member 21 are additionally provided.

Therefore, the sound insulation plate 6 substantially shields the frame 4 and contacts the floor material 40 via the floor base plate 5.

As shown in FIG. 2, the floor panels 1 can be arranged side by side and bridged to form a floor above the floor and a ceiling below the floor. The floor panel 1 is fixed by bolting its long and short sides along the outdoor wall of the house to the side piece 46 of the support fitting 45 at the upper end of the downstairs wall panel 44. The support fitting 45 also supports the lower end of the upper wall panel 50. Further, the indoor side portion can be bridged by bolting the short side to a joint fitting 52 screwed to the beam member 51.
