However, a floating floor structure is constructed in which floor panels d, d, etc. are arranged side by side on the cushioning material b via supports c such as floor joists. This floating floor structure has the effect that the floor impact force is absorbed by the cushioning material b, thereby reducing the transmission of impact noise to the downstairs.

擦による床鳴りが発生するという問題があつた。(Problem to be Solved by the Invention) However, in the conventional floating floor structure described above, the floor panel d is supported on the flexible cushioning material b which has a large cushioning effect for soundproofing purposes, so the floor panel d is supported against the floor impact force. The surface tends to vibrate up and down. In particular, as shown in Fig. 8, the floor panel d,
When an impact force P acts on the joint d, the lower gap between the side surfaces of the floor panels at the joint widens, the upper side surfaces of the floor panels rub against each other, and the joint sinks. As a result, there were problems in that not only the floor surface rippled, but also the floor rumbled due to friction between the side surfaces of the floor panels.

Even if the elastic material f is interposed in the joint part in this way, the bending deformation of the joint part remains as is, and the vibration caused by the undulation of the floor surface is transmitted to the floor slab a through the lower cushioning material.
The problem remains that the impact sound is transmitted to the floor below and that vibration insulation is not sufficient against the impact force at the joints. In addition, as mentioned above, the elastic material f
There is also the problem that the work to intervene is troublesome and the workability is poor.

The lower surface of each floor panel 3 and the mounting surface 6a are fastened together with nails or screws, and the air below the floor panel 3 is connected between the side surfaces of the adjacent floor panels 3, 3. They are joined with a gap 9 formed by the protrusion 7 so as to allow the flow to flow above the floor panel 3.

Plastic, wood cement board, etc. are used, and the material for the protrusion 7 may be the same as or different from the substrate 6, as long as it is a hard material that does not collapse under compression. In this case, the protrusion 7 has a width of approximately 5 to 30 mm, a height that is less than the thickness of the floor panel 3, and approximately half the thickness of the floor panel 3. Furthermore, the support 4 is not limited to a block-shaped support partially disposed on the lower surface of the floor panel 3 at the joint portion as shown in the figure, but may also be a rectangular support 4.
They may be arranged intermittently so that there are gaps between the four. Moreover, as the support body 4, a fourth
In addition to the one in which a protrusion 7 consisting of a single protrusion is provided at the center of the upper surface of the base plate 6 as shown in the figure, the protrusion 7 is formed by a pair of protrusion pieces as shown in Fig. 5. It may be.

を低減することができる。 Therefore, at the joint portion of each floor panel 3, 3, a gap 9 by the protrusion 7 is automatically formed between the side surfaces of each floor panel 3, 3 by the joint construction, so that the conventional method is not possible. As a result, there is no floor noise due to friction between the side surfaces of the floor panels, and the floor panel has excellent soundproofing properties. Furthermore, even if a floor impact force is applied to the joint part, since the joint part is connected with the protrusion 7 fitted, the upper surface side of the floor panel
It is on both abutting surfaces 7 of the protrusion 7 that the gap 9 tends to narrow.
a, 7a, and the expansion of the interval 9 on the lower surface side of the floor panel is suppressed by the fastening of the board part 6 to the mounting surface 6a, so bending deformation of the joint part is suppressed to a small level. This eliminates the occurrence of large vibrations such as undulations on the floor surface, providing an excellent walking feel and reducing the emission of impact noise downstairs.

It can be constructed without the need for additional parts or work, and does not cause deterioration in workability.

く行うことができるので有利である。 Furthermore, as shown in FIG. 3, the space 9 between the floor panels 3 and the protrusion 7 between the side surfaces of the floor panels 3 at the joint portion can be used as a space for underfloor wiring 10 and underfloor piping. Further, in this case, it is advantageous that wiring and piping work and maintenance can be performed without removing the floor panel 3.

Because the space 9 between the floor panels 3 and the 3 side surfaces communicates with the space below the floor panel 3, the floor panel 3
When an impact force is applied to the floor panel 3, the air below the floor panel 3 is pulled out from the joint part to the top of the floor panel 3 as shown by arrow A in FIG. Therefore, the transmission of impact force to the subfloor 1 via the air pressure can be reduced, and soundproofing properties can be further improved.

They were arranged at intervals of 450 mm, and wooden hollow panels with a thickness of 50 mm and a size of 1800 x 450 mm were placed on these supports as floor panels, and they were joined from the top with screws to form a floating floor.

As shown in Figure 6, the sound insulation performance of L-49 according to the Architectural Institute of Japan standard was achieved. Obtained. At the same time, in order to measure the deflection of the joint, a youth can was erected on the floor 300 mm away from the above-mentioned point of impact and the condition after the vibration was observed, and the can did not tip over.

This is the performance of L-55 based on the Architectural Institute of Japan standard.Also, to measure the deflection of the joint, the state of the youth can after vibration, which was placed on the floor 300 mm away from the point of impact, was that the can had fallen over, and the top and bottom of the surface It was confirmed that the movement was large. The impact sound level of only the floor slab was L-60 as shown in Figure 6.

It is possible to stably support the floor panel while maintaining a constant gap, and to connect the floor panel so that the air below the panel can flow through the gap above the floor panel, so that floor impact force does not act on the joint part of the floor panel. It is also possible to suppress and prevent the occurrence of floor rumble and rippling vibrations on the floor surface due to friction between the side surfaces of the floor panels, as well as to suppress the rise in air pressure directly under the floor panel and to transmit impact force to the subfloor through the air pressure. can reduce transmission,
As a result, it is possible to provide a structure with excellent soundproofing properties and a comfortable walking feel without impairing workability.
