Description

  The present invention relates to a partition wall structure such as a fireproof sound insulation partition wall in a building such as a reinforced concrete structure.

  Fig. 2 shows a typical configuration example of a sound insulation partition wall in a building such as a reinforced concrete structure. Guides such as runners not shown in the figure are provided on the floor and ceiling of the building, and a square material, etc. is provided inside the guide. A plurality of struts 1 are set up, a sound absorbing material 2 made of a refractory material or the like is provided between the adjacent struts 1, 1, and plate members 3 such as various boards are attached to both surfaces of the strut 1.

  The main performance required for the partition wall as described above is fireproof performance and sound insulation performance. Of these, the fire performance can be easily improved by a combination of constituent materials, but it is difficult to improve the sound insulation performance, and various ideas have been made for that purpose.

  For example, in order to improve the sound insulation performance of the wall, there are methods such as increasing the rigidity of the wall itself, increasing the wall weight, and providing an air layer in the wall. However, in these methods, as the rigidity and weight of the wall increase, the workability decreases and the construction cost increases. Or there is a problem that the living space is narrowed by the thickness of the wall.

  In order to solve these problems, a sound insulation partition wall basically composed of a composite material of a plate material, a support column, and a sound absorbing material is generally spread as a known technique. In order to further improve the sound insulation performance, it is preferable to provide an air layer. However, for that purpose, the wall thickness becomes thick, and the problem arises that the wall strength becomes weak because an air layer is provided between the column and the plate. Moreover, construction becomes difficult, for example, a spacer is interposed to provide an air layer.

  On the other hand, since the purpose of providing the air layer as described above is to block vibration, an invention has been proposed in which a similar effect is obtained by sandwiching a sheet such as a rubber material instead of the air layer. Yes. For example, in Patent Document 1 below, at least one board uses a heavy wall and a vibration isolation rubber is attached to the other board in a sound insulation structure partition wall made up of a board as a board, a base material as a support, and a sound absorbing material. The configuration is disclosed. Patent Document 2 below discloses a configuration in which a sound insulation sheet is laminated and joined to the inside of a board in a partition wall of a sound insulation structure including a board, a base material, and a sound absorbing material.

  However, any of the above is a configuration in which vibration isolation rubber or a sound insulation sheet is fixed to a support or a plate material, and if it is firmly fixed to increase wall strength, vibrations are likely to be transmitted and sound insulation may be reduced. On the contrary, if it is loosely fixed to increase the sound insulation, there is a problem that the wall strength is lowered. In addition, construction such as providing a heavy weight wall or attaching a sound insulation sheet to the inside of the board is difficult and inevitably costs high.

JP 2001-107493 A Japanese Patent Laid-Open No. 11-247321

  The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a partition wall structure that has high sound insulation performance, good workability, and can be constructed at low cost.

  In order to achieve the above object, the partition wall structure according to the present invention has the following configuration. That is, in the partition wall structure mainly composed of a plate material and a support, a hard sheet and a soft sheet are interposed between the support and the plate. In this case, in the case where the plate material is provided on both sides of the support column, a hard sheet is interposed between the one plate material and the support column, and a soft sheet is interposed between the other plate material and the support column, respectively. It is preferable to configure so that the hard sheet and the soft sheet are alternately arranged on the surface of the adjacent plate on the same plate material side. As said hard sheet, elastic bodies, such as hard rubber, can be used, for example, and as a soft sheet, what consists of porous materials, such as a soft sponge, can be used, for example.

  As described above, the partition wall structure according to the present invention firmly secures the sound insulating performance and firmly fixes the plate material and the column by interposing the hard sheet and the soft sheet between the column and the plate. Even if the wall thickness is reduced, sufficient sound insulation performance is ensured, the wall strength is strong, the workability is good, and the construction can be easily and inexpensively performed.

  Hereinafter, the present invention will be specifically described based on the embodiments shown in the drawings. FIG. 1 is a cross-sectional plan view showing an embodiment of a partition wall structure according to the present invention, and members having the same functions as those in the conventional example will be described with the same reference numerals.

  In the present embodiment, a sound absorbing material 2 is attached between adjacent struts 1, 1 arranged at a predetermined interval, and plates 3 such as various boards are attached to both sides of the strut 1 via hard sheets 4 and soft sheets 5. It is laid. In particular, in the case of the figure, a hard sheet 4 is provided between one of the plate members 3 provided on both sides of each support column 1 and the support column 1, and a soft sheet 5 is provided between the other plate material and the support column. In addition to being interposed, the hard sheets 4 and the soft sheets 5 are alternately arranged on the same surface side of adjacent struts.

  The role of each of the hard sheet 4 and the soft sheet 5 is to absorb the vibration of the plate 3 by the hard sheet 4 so as not to transmit the sound from the outside, and to simulate the sound not from the outside. The air layer is created by the soft sheet 5. Therefore, as the hard sheet 4, for example, an elastic body such as a relatively hard rubber may be used, and as the soft sheet 5, it is preferable to use a material made of a porous material such as a soft sponge.

  As a method for fixing the hard sheet 4 and the soft sheet 5 to the support column 2 and the plate material 3, any method may be used as long as it can adhere and fix, such as an adhesive or a screw. In order to obtain particularly high rigidity, it is preferable to use a combination of these fixing means. In particular, fixing by screws, that is, a fixing method in which screws are passed through the plate material 3 and the hard sheet 4 or the soft sheet 5 and screwed into the column is rigid. It is effective in improving. Even if it is firmly fixed with screws, the vibration absorption performance by the hard sheet 4 is not so lowered, and the soft sheet 5 has no problem in sound insulation performance because an air layer such as a porous layer and flexibility remain. Accordingly, if the hard sheet 4 and the soft sheet 5 are interposed between the support column 2 and the plate material 3 as described above, the plate material 3 and the support column 2 can be firmly fixed while sufficiently ensuring sound insulation performance. .

  The partition wall structure configured as described above can be easily installed by standing along runners (not shown) provided in advance on the ceiling and floor. Further, if another sheet material is stretched on the outside of each sheet material 3 to make it double tension, the sound insulation performance can be further improved.

  As described above, the partition wall structure according to the present invention has a sound insulation performance satisfactorily secured by interposing a hard sheet 4 and a soft sheet 5 between the support column 1 and the plate material 3, and the plate material and the support column. It is possible to construct partition walls with high sound insulation performance and high strength easily and inexpensively, and to increase the degree of freedom of partition wall design in the construction industry. Can do.
