Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel capable of firmly fixing a sound insulating plate by using a fixing member and improving quality and reducing production cost.

[0002]

2. Description of the Related Art In a building of a dry construction method, a floor panel forming the floor is, for example, as shown in FIG.
A joist material b and a field edge material c are attached to a peripheral frame a, which is a rectangular frame material.
And the floor base plate d and the ceiling base plate e are additionally provided on the lower surface thereof. Further, when such a floor panel is used as an upper floor, in order to prevent conversations on the upper floor and sounds of audio equipment and the like from being transmitted downstairs, the floor panel has a heavy sound insulating plate f in the surrounding frame a. Are arranged. Conventionally, such a sound insulating plate f has been manufactured by using the joist material b.
By attaching the sound insulating plate f to the fall prevention receiving material g,
It was arranged on the lower surface of the floor base plate d.

[0003]

However, in such a conventional device, since the sound insulation plate f is supported only by the receiving material g for preventing fall, its mounting strength is poor and the sound insulation plate f is loose. In addition to causing quality defects such as sticking, if a little, a gap is created between the sound insulation plate f and the floor base plate d, which causes a decrease in the sound insulation effect, and the use of the above-mentioned receiving material g increases the number of types of members, thus increasing production Increase costs. Also, it takes a lot of time to attach the receiving material g to the joist material b,
There are issues to be solved, such as poor productivity.

The present invention is based on the fact that the sound insulating plate is fixed to the floor base plate by driving the drive piece of the fixing metal fitting from below the sound insulation plate and bending the drive piece within the floor base plate. The purpose of the present invention is to provide a floor panel that can be achieved and can reduce the production cost, and can increase the mounting strength of the sound insulation plate to the floor base plate.

[0005]

In order to achieve the above-mentioned object, the floor panel of the present invention is a floor panel which is attached to an upper surface of a peripheral frame in which frame members are joined in a rectangular shape. A floor panel fixed by using a staple-like fixing metal fitting having a pair of driving pieces parallel to both ends, wherein the fixing metal fitting has a V-shaped cutout portion provided on one side surface of the driving material. As a result, the fixing piece is bent from below the sound insulation plate until the base piece contacts the lower surface of the sound insulation plate, and the driven piece is bent in the floor base plate to fix the sound insulation plate to the floor base plate.

[0006]

The underfloor is driven by driving a heavy sound insulation plate from below the sound insulation plate until the base piece contacts the bottom surface of the sound insulation plate with a staple-like fixing metal fitting having a pair of driving pieces parallel to both ends of the base piece. Fix to the ground plane. In addition, the driving piece has a
V-shaped notches are provided on one side surface so that the driving piece bends in the floor base plate together with the driving. This is because the floor base plate using particle board or the like has a higher hardness than a sound insulating plate such as a gypsum board, so that the tip of the driving piece bends at the cutout portion as soon as the tip reaches the floor base plate.

As described above, since the fixing metal piece is driven by contacting the base piece with the lower surface of the sound insulation plate and bending the driving piece, the sound insulation plate can be firmly attached to the floor base plate, and the mounting strength can be increased. It is possible to prevent quality defects such as rattling of the plate, and it is possible to omit a member for preventing the sound insulating plate from falling, thereby reducing the production cost.

Further, since such a fixing metal fitting is driven from one direction, it is easy to automate the driving by using an appropriate device, which is also useful for improving productivity.
