DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a wall having excellent sound insulation performance, and to a partition panel constituting the wall. In particular, the present invention relates to a partition panel in which a convex protrusion is provided on a panel flat portion between vertical ribs provided on the back surface of the panel to constitute a high-performance partition wall.

[0002]

2. Description of the Related Art A plurality of vertical ribs are provided on the back surface of a flat panel portion of a panel, and the lower floor slab to the upper floor slab are constructed with one partition panel without using studs, and the partition panels are connected side by side. A partition wall having one wall surface and a partition wall facing the other wall surface so that a gap is provided between the walls, and a sound absorbing material such as glass wool is interposed in the gap formed by the double walls. Is generally used (see JP-A-63-27645, JP-A-63-78942 and JP-A-2-164965).

FIGS. 9 and 10 show a partition wall 1 in which glass wool is interposed in the gap. The partition wall 1 is composed of a partition panel 2 which divides an internal space of a building and has two panels facing each other as shown in the figure. Further, the partition panel 2 is provided on the back surface of the panel flat portion 3.
A plurality of vertical ribs 4 extending from the lower edge to the upper edge are provided. The upper part of each vertical rib 4 is provided with a notch 7 for fitting a tongue piece 6a of an upper runner 6 fixed to an upper slab 5 of a building. The lower slab 8 of the building has the lower end of the partition panel 2 in contact with an L-shaped lower runner 9 and is fixed via a tapping screw 10. A gap is formed between the partition panels 2 and 2, and a glass wool 11 is provided therein.

FIG. 11 shows another type of partition panel. This partition panel 2 is different from the partition panel shown in FIG. 9 and FIG.
The only difference is that it is provided. The panel structure of these partition walls is excellent in workability because the upper cuts of the vertical ribs can be inserted into the upper runner fixed to the slab and fixed when fixing the partition panel. Further, even if displacement occurs in the upper and lower slabs due to an earthquake or the like, it is possible to effectively prevent the partition panel from sliding or cracking at the cut portion, thereby generating or breaking the partition panel. Furthermore, the partition panel is superior in terms of lightness, fire resistance, and sound insulation as compared with concrete-filled panels.

[0005]

SUMMARY OF THE INVENTION However, FIGS.
In the structure of the partition wall using the conventional panel as shown in FIG. 11, the level of the sound insulation structure notified by the Ministry of Construction, that is, D-40
Although the performance is obtained, the coincidence effect of the panel flat part between the vertical ribs (When the sound insulation layer has rigidity, the rigidity determines the propagation speed of the bending wave propagating on the sound insulation layer together with its inertia, and the sound insulation by this The vibration distribution of the layer may coincide with the vibration force distribution of pushing and pulling the incident sound wave to the sound insulation layer at a certain frequency, in which case a kind of resonance occurs,
A transmitted wave is generated efficiently. Say this phenomenon)
D-5 on the second rank
It is difficult to ensure performance equivalent to 0.

In general, a fire-resistant board (fire-resistant board) is provided in a single layer or a plurality of layers on both wall surfaces of the partition wall of the above structure to form a fire-resistant and sound-insulating partition wall having a sound insulation performance of D-50. The present invention does not require a fireproof board (fireproof board) to be overlaid, and simply inserts (inserts) a sound absorbing material such as glass wool into the space of opposing partition panels.
It is an object of the present invention to provide a high-performance sound-insulating partition panel capable of obtaining considerable sound-insulating performance.

[0007]

According to the present invention, in order to achieve the above object, a partition wall composed of independent double walls for dividing an internal space of a building is formed, and a plurality of vertical walls are provided on the back surface of the panel flat portion. A rib is provided, and in the partition panel fixed between the lower floor slab and the upper floor slab of the building, one or more convex protrusions are provided between the vertical ribs of the partition panel in parallel with the vertical rib. It is characterized by the following. Further, in the present invention, the width of the convex protrusion is preferably 1/20 to 1/1 between the vertical ribs.
5 and the height of the projection is 1/4 to 1 of the thickness of the panel flat portion, which is more effective.

That is, one or more convex protrusions are provided in parallel with the vertical ribs on the flat portion between the vertical ribs provided on the back surface of the panel, so that the sound pressure distribution on the panel surface and the natural vibration distribution on the panel flat portion are improved. Prevents the sound transmission loss from being reduced due to the coincidence effect of the flat plate portion, and the glass wool can be applied to the facing panel space even if the fire-resistant plate material (fire-resistant board) is not overlaid. By simply interposing (inserting) such a sound absorbing material, a high performance sound insulating partition panel having sound insulating performance equivalent to D-50 can be obtained.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A high-performance sound insulating partition panel of the present invention is a conventional partition panel, that is, a partition panel having a plurality of vertical ribs provided on the back surface. By forming a partition panel having one or more projections in parallel with the projections, a high-performance sound-insulating partition wall having higher sound insulating performance, which cannot be obtained by a conventional partition panel, is obtained.
