Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a partition used to partition a building into a plurality of rooms.

[Conventional technology]

Conventionally, in the case of partitioning a building into a plurality of rooms in an apartment house, a hospital, an office, etc., for example, the means shown in FIGS.

That is, as shown in FIG. 5, first, the upper runner a and the lower runner b made of a long iron plate having a U-shaped cross section are fixed to the ceiling and floor of the building, respectively, and then, as shown in FIG. Plural studs d having a through hole c between the runners a and b
Are arranged and fixed at predetermined intervals. Next, if necessary,
As shown in the figure, the penetration material e for preventing steadying of the stud d is respectively passed through the through holes c of the plurality of studs d, and thereafter, as shown in FIG. 8, from the plaster board etc. to the front side and the rear side of the stud d. Each of the interior plates f is fixed by using a tapping screw or the like, and a partition g is constituted by this, and the interior of the building is partitioned into a plurality of rooms.

[Problems to be solved by the device]

However, since the partition g described above fixes the interior plates f, f directly to the stud d, both interior plates f, f cause a resonance phenomenon due to the spring action of the air layer between the interior plates f, f. When the sound of one room adjacent to each other is transmitted to the other room or there is a vibration source such as a cooling tower, a washroom, or a kitchen in the next room or the upper and lower floors, the solids derived from this vibration source. There is a problem that the sound insulation is inferior such that sound is transmitted to the interior plates f, f through the studs d, and solid sound is radiated from the wall surface into the room. In this case, some conventional partitions aim at sound insulation by filling a sound absorbing material between both interior plates f, f, but it is difficult to say that the current level of performance is sufficient, especially solid sound. No measures have been taken against.

The present invention has been made in view of the above circumstances and has an excellent sound insulation property, and the sound of the next room can be heard by the resonance phenomenon caused by the spring of the air layer, or the vibration of the next room or the upper and lower floors. An object of the present invention is to provide a partition that can favorably prevent solid sound originating from the source from being radiated from the wall surface of the interior plate.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a plurality of studs at predetermined intervals between an upper runner fixed to a ceiling of a building and a lower runner fixed to a floor of a building. While standing upright, interior plates are attached to the front and rear sides of the studs so as to cover the space formed between the studs, and the interior plates divide the building into a plurality of rooms. In the partition
The above-mentioned one bracket of the vibration-proof member, which is made of a rubber-like elastic body and is fixed to two vibration-isolating members which are separated from the stud and whose one side is separated from the stud, is separated from the stud. And the other bracket is connected to the stud, and one of the interior plates is separated from the stud to be fixed to the wall base material, and the other of the interior plates is connected to the stud. And is fixed directly or via a vibration isolator.

In this case, the runner is a supporting member that is fixed to the ceiling and the floor to support the stud, and the stud is a structural member that is held between the two runners to attach the interior plate. There is no particular limitation on the shape and material of the. Further, the shape and material of the interior material are not limited.

[Action]

In the present invention, due to the above configuration,
As will be apparent from an experimental example described later, resonance of the interior plate and transmission of solid sound from the stud to the interior plate can be almost certainly prevented by the damping effect of the vibration isolator.

Next, the present invention will be described in detail with reference to examples, but the present invention is not limited to the following examples.

〔Example〕

 FIG. 1 shows a partition according to an embodiment of the present invention.

In the figure, reference numeral 1 denotes a stud made of an iron plate having a substantially U-shaped cross section. This stud 1 is not shown, but like the one shown in FIGS. 5 to 8, the upper runner and the floor fixed to the ceiling of the building. A plurality of lower standing runners are erected at predetermined intervals. Also, on the side of each stud 1,
A plurality of anti-vibration members 2 are attached in the state of being separated from each other by a predetermined distance along the height direction (in the drawing, one anti-vibration member 2 is shown for each stud 1). As shown in FIG. 2, the vibration isolator 2 has a mounting plate 4 and a vibration isolator fixing plate 5 integrally connected in an L shape on the upper surface of a vibration isolator 3 made of a rubber-like elastic body. The lower surface of the fixing plate 5 of the upper bracket 6 is fixed by baking adhesion or the like, and the mounting plate 7 and the vibration-proof material fixing plate 8 are attached to the lower surface of the vibration-proof material 3 by L.
The upper surface of the fixing plate 8 of the lower bracket 9 that is integrally connected in a letter shape is fixed in the same manner as above, and both the mounting plates 4 and 7 are provided in a mutually orthogonal state. Two mounting holes 10 and 11 are formed in both mounting plates 4 and 7, respectively. Then, by screwing the screws into the studs 1 through the mounting holes 11 of the lower bracket 9, the vibration isolation members 2 are screwed to the studs 1. In this state, the vibration isolator 3 and the upper bracket 6 are slightly separated from the stud 1. Further, reference numeral 12 in the figure is a long wall base material (copper edge) made of an iron plate attached to the vibration isolator 2 and having a substantially U-shaped cross section.
Is. The wall base material 12 has the mounting plate 7 of the upper bracket 6 inserted therein and is screwed to the mounting plate 7, and is connected to the stud 1 while being slightly separated from the stud 1. Has been done. Furthermore, in the figure 13
Shows a front interior plate made of gypsum board, and this front interior plate 13 is screwed to the wall base material 12 in a state of being slightly separated from the stud 1. In the figure, 14 is a rear interior plate made of gypsum board, and this rear interior plate 14 is directly screwed to the stud 1.

FIG. 3 shows another embodiment of the present invention. In FIG. 3, the same components as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, as the front interior plate 15 and the rear interior plate 16, a sound insulating plate having a sandwich structure in which a rubber damping material 18 is sandwiched between gypsum boards 17, 17 is used. Also,
A sound absorbing material 20 is filled in the space 19 between the interior plates 15 and 16.

In the partition of each of the above-described embodiments, the front interior plates 13, 15 are attached to the stud 1 via the vibration isolator 3, so that the front interior plates 13, 15 resonate with the outer interior plates 14, 16 and are adjacent to each other. The sound of one room is transmitted to the other room, and the solid sound originating from the vibration source of the adjacent room or the upper and lower floors is transmitted to the front interior plate 13,15 via the stud 1, and the interior plate 13,15 Radiation from the wall surface of the is effectively prevented by the damping effect of the vibration isolator 3, and excellent sound insulation is exhibited. The partition of the embodiment shown in FIG. 3 uses a sound insulating plate having a sandwich structure in which rubber damping materials are sandwiched between the inner plates 15 and 16, and the sound absorbing member 20 is interposed between the inner plates 15 and 16. Since these are filled, the sound insulation plates 15 and 16 and the sound absorbing material 20 have higher sound insulation performance due to the vibration damping and sound absorbing effects.

In the above embodiment, only the front interior plates 13 and 15 are attached to the stud 1 via the vibration damping material 3.
If necessary, the rear interior plates 14 and 16 can also be similarly connected to the stud 1 via the vibration isolator 3, whereby higher sound insulation can be obtained. Further, other configurations may be variously modified without departing from the scope of the present invention.

[Effect of device]

As described above, the partition of the present invention is made of a rubber-like elastic body, and is a vibration damping member formed by fixing two brackets which are spaced from each other to the vibration damping material which is spaced from the stud, and one of which is spaced from the stud. While connecting one of the brackets to a wall base material disposed apart from the stud, connecting the other bracket to the stud, and separating one of the interior plates from the stud to fix the wall base material, By fixing the other of the interior plates directly to the studs or via a vibration isolator, it is possible to suppress the resonance phenomenon of the interior plate due to the damping effect of the above-mentioned vibration isolator and prevent hearing of the sound in the adjacent room. It is possible to prevent the solid sound originating from the vibration source from being transmitted to the interior board through the studs and being radiated from the wall surface of the interior board. It is the casting. Therefore, according to the partition of the present invention, for example, it is possible to provide a living room adjacent to a toilet, a bathroom, etc. in an apartment house, and it is possible to make the floor plan in the apartment house more flexible and to streamline the construction. Reduction of solid noise in such cases,
In particular, it is possible to reduce the noise of water supply and distribution.

Hereinafter, the effects of the present invention will be specifically shown by experimental examples.

[Experimental example]

The sound insulation performance of the partition of the present invention shown in FIG. 1 and the sound insulation performance of the conventional partition shown in FIGS. 5 to 8 were compared and tested.
In this case, the sound pressure level passing through each partition was measured for each frequency band, and the difference in sound pressure level between the rooms was examined. The higher the sound pressure level difference between the rooms, the higher the sound insulation performance.

The results are shown in the graph of FIG. The white plot (○) in Fig. 4 shows the result of the partition of the present invention, and the black plot (●) shows the result of the conventional partition. From this graph, it is possible to improve the sound insulation performance by supporting the interior plate with a vibration-proof material, especially at a low level. It is recognized that significant improvements in the frequency range are possible.
