Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof double floor structure by the joist construction method.

[0002]

2. Description of the Related Art Conventionally, as a double floor structure by the joist construction method, as shown in FIG. 7, joists 3 are installed on upper portions of support legs 1 placed on a floor base material 2 such as a floor slab. And a double floor panel 4 is laid on top of this joist 3,
The double-floor panel 4 is installed in a state of being floated from the floor base material 2, and thus a double floor is constructed.

The end portion of the joist 3 close to the wall surface 5 is placed on the joist 6 when the end portion of the joist 3 is set on the upper part of the bundle 19 arranged along the wall surface 5. An anti-vibration rubber 30 is interposed between the joist 6 and the joist 3 in order to ensure vibration-proofing and sound-proofing, and each member is fixed to the joist 3 from the upper surface side. The fixing nails 31 are inserted into the joist 6 through the vibrating rubber 30 so that they are connected and integrated with each other.

[0004]

However, in the conventional example as described above, the vibration-proof rubber 30 is disposed between the thick joist 6 and the joist 3 in order to secure the vibration-proof and the sound-proof. However, since the anti-vibration rubber 30 is fixed by penetrating the anti-vibration rubber 30, vibration is transmitted to the joists 6 through the anti-vibration nail 31, and the anti-vibration property and the sound insulation property are significantly reduced. There was a problem of doing. Also, anti-vibration rubber 3
When 0 is fixed through the fixing nail 31, the fixing nail 31 impedes the elastic effect of the vibration-proof rubber 30.

That is, even if the anti-vibration rubber 30 is arranged between the joist 6 and the joist 3, if the anti-vibration rubber 30 is fixed by penetrating it with the fixing nails 31, the original anti-vibration property and sound insulation of the anti-vibration rubber 30 are obtained. It was not effective. The present invention is intended to solve the above problems, and a soundproof double-floor structure capable of connecting a joist and a joist through a vibration-proof rubber without lowering the vibration-proof and sound-proof properties. It is the one we are trying to provide.

According to the first aspect of the present invention, the end portion of the joist disposed close to the wall surface is disposed above the joist, and the fixing member provided with the support plates on the upper and lower surfaces of the vibration-proof rubber is the joist. Is disposed between the lower surface of the end of the and the upper surface of the joist, and the connecting nail projecting above the upper surface of the upper support plate is driven into the lower surface of the end of the joist,
Since the connecting nail protruding below the lower surface of the lower support plate is driven into the upper surface of the outer joist, the upper supporting plate provided on the upper side of the vibration-proof rubber and the joist are connected by the connecting nail. It is connected and fixed to each other, and the lower support plate provided on the lower side of the anti-vibration rubber and the joint joist are connected and fixed to each other with the interlocking nail. It is possible to exert the original anti-vibration and anti-vibration effect of the anti-vibration rubber without any damage, and connect the joist and joist through the anti-vibration rubber without lowering the anti-vibration and sound-proof properties. Is what you can do.

According to a second aspect of the present invention, the end portion of the joist disposed close to the wall surface is disposed above the joist, and the fixing member provided with the support plates on the upper and lower surfaces of the vibration-proof rubber is the end of the joist. Between the bottom surface of the joist and the top surface of the joist, and a connecting piece formed by bending the end of the upper support board upward is driven into the bottom surface of the end of the joist to support the bottom support board. Since the connecting piece formed by bending the end part of the bottom is driven into the upper surface of the outer joist, the upper supporting plate provided on the upper side of the vibration-proof rubber and the joist are connected to each other by the connecting piece. The lower support plate provided on the lower side of the anti-vibration rubber and the upper joist are connected and fixed to each other by a connecting piece. The anti-vibration rubber is capable of exerting its original anti-vibration effect and sound-proof effect without lowering the anti-vibration and sound-proof properties. It is capable of connecting the joists and the joist when through.

According to a third aspect of the present invention, the end portion of the joist arranged close to the wall surface is arranged above the outer joist, and notches are provided at the upper end corners along the longitudinal direction to cross the joist. Place the end of the joist on the anti-vibration rubber that is formed in a convex shape and is placed on the upper surface of the joist. Since it is in contact with the upper surface of the notch, it prevents the joists from shifting laterally or jumping up due to the support tool, and the anti-vibration rubber sticks to the joists without the connecting nails being placed through. Since it can be interposed between the joists, it can exhibit the original vibration-proof and sound-proof effects of the anti-vibration rubber. It is possible to connect the joist and the joist via.
