2. Description of the Related Art Conventionally, assembling a floor panel to a beam is shown in FIG.
And the method shown in FIG.

In the method shown in FIG. 8, the floor panel P is attached to the beam by attaching the joist fixing hardware a to the beam at a predetermined position on the lower surface of the reinforcing member (hereinafter also referred to as joist) s of the floor panel P. This is done by fixing it to the flange f. In this method, it is necessary to release the lock of the fixing member of the joist fixing hardware a from the back surface of the floor panel P to restore the spring, and the restoring force presses the fixing portion b against the lower surface of the upper flange f of the beam. become.

However, this work is not performed immediately after the floor panel P is set on the beam because of the process of the installation work of the building. That is, for a while after the floor panel P is set on the beam, the floor panel P is in a temporarily placed state without being fixed to the beam.

Then, the floor panel P in the temporarily placed state is used as a work scaffold for subsequent work. In this case, if there is no opening in the floor, there is no concern that the floor panel P will shift, but if there is an opening for a blow-through or stairs, the floor panel P may shift. Therefore, there arises a problem that the position must be adjusted again. Not only that, but worse, there is a possibility that a fall accident may occur from the gap caused by the floor panel P being displaced.

In the method shown in FIG. 9, the floor panel P is fixed to the beam by attaching a fixing metal piece z such as a Z clip to a predetermined position on the lower surface of the joist s. In this case, the same problem as described above occurs.

Further, in any of the above methods, it is necessary to work from the rear surface of the floor panel P, and there is a problem that the number of steps is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, but the present invention is not limited to this embodiment.

The floor panel according to the present invention is shown in FIG. 1, and the lower surface 1a of the reinforcing member (joist) 1 of the floor panel P is provided with self-actuating fixing means 2 and 2. This mounting position is appropriately determined according to the type and size of the self-actuating fixing means 2. The specific position is determined by, for example, an experiment.

In the embodiment shown in FIG. 1, the self-actuating fixing means 2 has a curved portion 3 at the tip as shown in FIG.
The leaf spring 4 formed with is used. This leaf spring 4
Is attached to the lower surface 1a of the joist 1 at a predetermined position with, for example, wood screws 5. Therefore, a mounting hole 6 is formed at a predetermined position of the leaf spring 4. Although the number of the holes 6 is two in the illustrated example, the number is not limited to two and may be appropriately adjusted according to the size of the leaf spring 4.

The curved portion 3 formed at the tip of the leaf spring 4 serves as a guide portion for attaching the floor panel P to the beam H and a fixing portion for fixing the floor panel P to the beam H. . Therefore, the shape of the tip portion of the leaf spring 4 is not limited to this, and may be any shape as long as it achieves the above-described action and effect.

Next, a method of assembling the floor panel P provided with the self-actuating fixing means 2 to the beam H will be described.

Assembly Method 1 (See FIGS. 3-4) Step 1: Position the floor panel P substantially horizontally above the beam H (see FIG. 3).

Step 2: The floor panel P is gradually lowered until the curved portion 3 of the leaf spring 4 contacts the flange end portion Ht of the beam H.

Step 3: The curved portion 3 is the flange end portion Ht.
With the floor panel P supported by the beam H, both ends of the floor panel P are simultaneously pressed to place the joist 1 on the flange upper surface Ha of the beam H (see FIG. 4). At this time, the bending portion 3
Elastically deforms to promote the lowering of the floor panel P, and when the joist 1 is placed on the flange upper surface Ha of the beam H, it elastically recovers and abuts the flange lower surface Hb of the beam H, and the joist lower surface 1a causes the flange Hf of the beam H to contact. To pinch. This automatically fixes the floor panel P to the beam H.

Assembly Method 2 (See FIGS. 5-7) Step 1: Position the floor panel P diagonally above the beam H. In the example shown in FIG. 5, the positioning is performed to the lower right.

Step 2: The floor panel P is lowered while being inclined, and one end of the floor panel P is positioned near the flange upper surface Ha of the beam H.

Step 3: At the end of the floor panel P positioned near the flange upper surface Ha of the beam H, the flange Hf of the beam H is inserted into the gap between the joist lower surface 1a and the curved portion 3 and temporarily attached. In the example shown in FIG. 6, the right beam H is temporarily attached.

Step 4: The other end of the floor panel P is pressed and the floor panel P is moved horizontally (to the right in the illustrated example), and the joist 1 is placed on the upper surface Ha of the flange of the beam H. Place (see FIG. 7). At this time, in the leaf spring 4 on the pressed side, the curved portion 3 is elastically deformed to facilitate the lowering of the floor panel P, and the joist 1 is attached to the beam H as in the above.
When it is placed on the flange upper surface Ha of the beam H, it elastically returns to contact the flange lower surface Hb of the beam H, and the flange Hf of the beam H is sandwiched between the joist lower surface 1a and the curved portion 3. Further, the flange Hf on the temporarily attached side is further pushed between the bottom joist lower surface 1a and the curved portion. This automatically fixes the floor panel P to the beam H.

As described above, in this embodiment, the floor panel can be fixed to the beam only by the work from the upper surface of the floor panel.

In the present embodiment, the self-actuating type fixing means is constructed by installing a pair of leaf springs each having a curved portion at the tip thereof at a predetermined position of the joist. However, the self-actuated fixing means is not limited to this, and any means that can fix the floor panel to the beam by only working from the top surface of the floor panel can be adopted.

[0029]

As described above in detail, in the present invention, since the reinforcing member of the floor panel is provided with the self-actuated fixing member, the floor panel is fixed to the beam only by the work from the upper surface of the floor panel. can do. Moreover, since the fixing is completed when the floor panel is set on the beam, there is no fear that the floor panel will be displaced when the floor panel is used as a work scaffold thereafter, and therefore, there is no risk of a fall accident. Therefore, work safety can be improved.

Further, since the work from the back surface of the floor panel is eliminated after the floor panel is set on the beam, the working process can be shortened and the installation cost can be reduced.
