And a panel with a tatami mat, a flooring, a carpet, or the like, and a panel with anti-vibration supporting legs of about 500 to 1000 mm square (the anti-vibration supporting interval is also 5 mm).
(From 1000 to 1000 mm) was generally placed on a slab, on which a floor such as a flooring or a tatami mat was finished. In addition, in conventional free access floors for business use, floor base panels with supporting legs (for example, 500 mm square panels made of aluminum or resin) are spread without gaps, and discarded or pasted thereon. Was doing.

[0003] However, the above-mentioned conventional floor structure is as narrow as about 500 to 1000 mm between the vibration-isolating support legs, and there is also a support point in the middle of the low rigidity slab of the building structure slab, and the number of support points is small. Due to the large number, there are problems such as poor sound insulation performance (floor impact sound performance). In order to improve the sound insulation performance, it is necessary to increase the distance between the supporting legs, but in that case, it is necessary to enlarge the large cross section, which results in a high finished surface and a narrow living space. In addition, there have been problems such as an increase in cost and an increase in labor, making construction difficult. In addition, the conventional joist floor structure has problems such as difficulty in leveling and level adjustment, and the construction is complicated.

FIG. 5A shows another embodiment in which the supporting leg mounting groove 3e is formed in the widthwise end surface of the floor base panel 3, and the lower surface plate 3b is provided at both ends with intermediate portions. In this embodiment, a step is formed so as to be positioned higher, and a support leg mounting groove 3e is formed in this step. With this configuration, not only can the floor base panel 3 be supported extremely stably, but also, as shown in FIG.
e, the vibration isolating rubber 6a of the supporting leg 6 attached to the base plate e can be positioned above the level of the lower surface plate 3b. As a result, the total height of the floor structure can be further reduced and the living space can be further widened. . In particular, when the entire support leg 6 can be completely stored above the lower surface plate 3b (on the upper surface plate 3a side), flat stacking is possible even with the support leg 6 attached.

FIG. 5B shows another embodiment in which the supporting leg mounting groove 3e is formed in the widthwise end surface of the floor base panel 3, similarly to the embodiment of FIG. 5A. However, in this configuration, in addition to the above advantages, the structural strength is high, and the stable floor base panel 3 can be provided.

In the embodiment of the floor structure shown in FIG. 2, a plurality of floor panels 3 are arranged side by side at predetermined intervals. However, the floor panels 3 may be laid in a state where the floor panels 3 are in contact with each other without any gap. . In this case, as shown in FIG. 6 (A), a protrusion 3f is formed at one end of the floor base panel 3 and a recess 3g is formed at the other end, thereby forming a joining means. As described above. In the present embodiment, the above-mentioned laminating material 4 can be omitted.

[0018]

EXAMPLE On a slab 200 mm RC, an aluminum alloy (JIS A6063 T6 extruded material) width 541 was used.
4 mm (mm), 70 mm height panels (FIG. 4 (A)) are arranged at 43 mm intervals, and a control panel (t = 12 mm) is stuck thereon, and the flooring (t) is stuck.
= 15mm), and the distance between the floor panel and the slab is 6 mm.
0 mm, 50 mm thick glass wool (32 kg / m
A sound was generated in a room having a floor structure where 3) was arranged (walls were also soundproofed), and the average sound pressure level difference (D value) was measured in a room below the floor where no soundproofing was performed. As a result, D-Num = 69 and high sound insulation was obtained. When the floor was made only of the skeleton slab and the wall portion was made to have the same condition as a comparison object, D-Num = 51, which proved that the present invention was effective. In addition, the floor impact sound level was as good as light floor attack sound level LL-Num = 34 and heavy floor attack sound level LH-Num = 46.

[0019]

As described above, 1) a long upper plate, a lower plate having the same shape as the upper plate, and these face plates are integrally joined to each other to be held at predetermined intervals in parallel and to form a large number of hollow portions. And a support leg mounting groove integrally formed in the longitudinal direction, and is formed as a metal extruded shape member such as an aluminum alloy, so that a lightweight and highly rigid floor base panel can be provided. Can be reduced or the spacing can be increased. 2) By forming the upper plate, the lower plate, and the ribs in a truss structure, it is possible to form a lightweight, high-strength flooring panel with a reduced thickness. 3) Filling the hollow portion with a sound absorbing material and / or a vibration damping material, attaching these materials to ribs, etc., and making holes in the lower surface plate as appropriate to improve the sound insulation performance of the floor base panel. It can be further improved. 4) By constructing the support leg mounting groove so as to be included in the hollow portion, it is possible to prevent the floor mounting panel from being stored in a flat stacked state or the mounting groove from being damaged during transportation. 5) By forming the support leg mounting groove near the end of the floor base panel or on the side end surface, the floor base panel can be stably installed or installed low. 6) By appropriately providing joining means at both side ends of the floor base panel, adjacent floor base panels can be stably installed without any level difference. 7) Since the support legs are attached only to the support leg attachment grooves of the floor base panel and are installed on the slab of the building, the construction is easy and the sound insulation performance of the floor base panel is improved. For example, it is possible to make adjustments such as increasing the length of the support legs on the second and higher floors to increase the sound insulation, and lowering the support legs and increasing the living space on the first floor, which does not require much sound insulation. 8) Since the support legs are composed of the vibration-isolating rubber, the support fittings, the bolts, and the fixing nuts, the floor base panel can be easily installed in the support leg mounting grooves, and the level of the floor base panel can be easily adjusted. Further, level adjustment between adjacent floor base panels is easy. 9) In addition, the lower surface plate is formed with a step at the side end so as to be located higher than the intermediate portion, and the support leg mounting groove is formed in this portion, so that the distance from the skeleton slab to the floor base panel is reduced. The adjustment allowance increases, and the correspondence to the usage pattern expands. 10) By mounting the support legs only in the support leg mounting grooves at the longitudinal ends of the floor base panel, the support legs can be positioned near the end of the highly rigid slab, and as a result, the floor base panel The impact sound is less likely to be transmitted to the skeleton slab and, conversely, the impact sound of the skeleton slab is less likely to be transmitted to the floor panel, and the sound insulation performance is improved. 11) By providing a gap between the adjacent floor base panels, it is possible to reduce the number of floor base panels to be installed, thereby reducing the cost. Becomes 12) By installing without providing a gap between adjacent floor base panels, it is possible to omit a laminating material according to the use condition of the floor, which is economical.
