である。[Detailed description of the invention] The present invention relates to a soundproof partition wall, and more specifically, it is used for soundproofing in noisy rooms or spaces, especially offices and stores located under railway overpasses, offices installed inside factories, etc. This relates to soundproof partition walls.

発揮することができないという欠点がある。 Offices, stores, etc. located under railway viaducts are affected by vibrations whenever a railway vehicle passes over the viaduct, and offices located within factories are affected by vibrations from the factory machinery, etc. Various vibrations generated from the equipment are transmitted to the walls and generate loud noise. Conventionally, gypsum boards, flexible boards, etc. have been used as interior materials, wall materials, etc. for partitioning rooms with loud noises, but such gypsum boards, flexible boards, etc. have low vibration damping performance and are difficult to prevent from transmitted vibrations. It has the disadvantage that a sufficient soundproofing effect cannot be achieved because solid-state sound is generated and the soundproofing performance is deteriorated in the low frequency resonance region and coincidence.

Hz以下に於て0.1以上であることが望ましい。 Normally, the solid sound generated by the vibration of partition walls installed in various indoor rooms as mentioned above is particularly low at 250 Hz.
Mainly in the low frequency range around 100Hz, the loss coefficient of plasterboard and flexible board is in this frequency range.
0.01 or less. On the other hand, in order to achieve sufficient soundproofing effect, the loss coefficient must be 250.
It is desirable that it be 0.1 or more at frequencies below Hz.

充填して成る防音間仕切壁にある。 The present invention provides a soundproof partition wall with excellent soundproofing effects that eliminates the drawbacks of gypsum board and flexible board as described above. A soundproof partition wall is provided in which damping panels having a body-interposed structure are arranged and fixed to opposite sides of the members via connecting members, and a porous sound absorbing material is filled between the damping panels.
以下添附図面を参照しつつ、単なる例示として
ではあるが本考案をさらに具体的に詳述する。 The present invention will now be described in more detail, by way of example only, with reference to the accompanying drawings.

In the drawing, 10 indicates a damping panel, 11 and 12 are made of flexible board on one side and plasterboard on the other, and there is a wall between them. A damping panel is constructed by inserting a viscoelastic body 13 and pasting it with adhesive or the like.

を250Hz以下にて0.1以上とすることができる。 Here, the thickness of the viscoelastic body 13 is 1/30 or more of the total thickness of the gypsum board or flexible board,
Furthermore, when normally used in offices and stores, the static elastic modulus Es of the viscoelastic body at room temperature 0 to 30°C is 5.0.
×10 7 dyne/cm 2 or less is desirable, and thereby the loss coefficient desired for the damping panel 10 can be set to 0.1 or more at 250 Hz or less.
