Description

  The present invention relates to a partition wall structure used for a general house or a collective house.

  Conventionally, partitioning has been performed using a partition wall structure using a conventional construction method or a wall panel. Generally, a gypsum board that is easily available is generally used as the wall surface of the partition wall structure.

  On the other hand, although it appears remarkably in the water-circulating system, there is a case where it is required to insulate daily noise and the like with these partition wall structures. However, it is difficult to provide the necessary sound insulation performance with the partition wall structure that is normally used, and additional sound insulation means must be provided.

  This sound insulation means can be performed by increasing sound transmission loss of the entire partition wall structure, thereby suppressing sound propagation and achieving sound insulation. For example, JP-A-11-1976 discloses a gypsum board. An example of a wall in which two sheets are stacked and a so-called gypsum board is additionally attached is shown.

On the other hand, the inter-room sound pressure level difference of gypsum board is mainly determined by the thickness, and the inter-room sound pressure level difference tends to increase as the frequency increases, but the resonance transmission frequency region and the coincidence frequency region differ. It has been found that the value of the difference in sound pressure level between rooms decreases in two areas (sound insulation performance deteriorates). Therefore, it is desired to improve the sound insulation performance of the partition wall in this audible frequency region.
Japanese Patent Laid-Open No. 11-1976

  This invention is invented in view of the said background art, The subject is providing the partition wall structure which can improve the room sound pressure level difference characteristic of the partition wall in an audible frequency area | region.

  In order to solve the above-mentioned problem, the present invention according to claim 1 is provided such that a column body standing between a floor and a ceiling and juxtaposed to each other, and a plurality of column bodies on both sides of the column body are provided. A partition wall body composed of a surface gypsum board that closes the gap, and is attached to any one side of the surface gypsum board of the partition wall body so as to cover a predetermined range of the surface gypsum board on the one side, The partition wall structure consists of an auxiliary board thinner than the surface gypsum board.

  In the present invention according to claim 2, in addition to the above, the auxiliary board is a gypsum board thinner than the surface gypsum board.

  Moreover, in this invention which concerns on Claim 3, in addition to the above, the column body is made into the vertical member of the frame body of the wall panel comprised by sticking a surface gypsum board on both surfaces of a frame body.

  In addition, in the present invention according to claim 4, in addition to the above, the auxiliary board is provided so as to cover the vertical butt portion of the adjacent surface gypsum board.

  In the partition wall structure of the present invention according to claim 1, by attaching an auxiliary board thinner than the surface gypsum board, the mutual coincidence characteristics can be shifted in the high frequency direction, and the sound insulation performance of one coincidence frequency region can be reduced. The decrease can be compensated for by the other sound insulation performance, so that the sound insulation performance of the entire partition wall can be improved.

  In the partition wall structure according to the second aspect of the present invention, in addition to the above effect, the auxiliary board is a gypsum board that is generally easily available, so that the acquisition cost is reduced and procurement is facilitated.

  In the partition wall structure according to the third aspect of the present invention, in addition to the above effects, a similar sound insulation effect can be obtained at a construction site constituted by wall panels.

  In the partition wall structure of the present invention according to claim 4, in addition to the above effect, the auxiliary board is provided so as to cover the vertical butt portion of the surface gypsum board, thereby reducing the propagation of sound leaking from this portion. It becomes possible.

  The best mode of the present invention will be described in the following examples.

  In this embodiment, FIG. 1 shows a conventional partition wall structure using a partition wall structure, and FIG. 2 shows a partition wall structure using a wall panel. Both have the same basic structure. . 3, 4, 6, and the like show only the figures using the wall panel, but the same structure can be considered when a normal partition wall structure is used. In the figures used in the present application, the thickness of the surface gypsum board and the auxiliary board is exaggerated for the sake of explanation.

  In the embodiment of the present invention with a partition wall structure using a conventional construction method shown in FIG. 1, a column 1 standing between a floor and a ceiling and juxtaposed with each other, and a plurality of columns on both sides of the column 1 A partition wall body 3 including a surface gypsum board 2 provided over the body 1 and closing between the floor and the ceiling, and a surface gypsum board on one side of the surface gypsum board 2 of the partition wall body 3 The partition wall structure is composed of an auxiliary board 4 that is thinner than the surface gypsum board 2 and is attached so as to cover a predetermined range of 2.

  Further, the auxiliary board 4 uses a gypsum board thinner than the surface gypsum board 2, and the auxiliary board 4 is further provided so as to cover the vertical butt portion 81 of the adjacent surface gypsum board 2.

  The partition wall body 3 separates the room A and the room B, and the partition wall body 3 is provided with an opening 5. Further, another partition wall is formed in contact with the partition wall body 3. Then, an auxiliary board 4 is additionally attached to the room A side of the partition wall body 3 that separates the room A and the room B, and the end (the left part in the figure) of the auxiliary board 4 abuts against the other partition wall. ing. Finally, a finishing material (not shown) such as a cloth is attached to the surfaces of these partition walls as a finishing treatment. In the present embodiment, for example, the room A is considered as a watering area such as a toilet, and the room B is considered as a living room area such as a bedroom.

  The auxiliary board 4 is preferably provided on the side of the other partition wall that contacts the partition wall main body 3. This is because the auxiliary board 4 extends to the opening 5 when the auxiliary board 4 is provided on the side opposite to the other partition walls, particularly when the partition wall main body 3 is provided with the opening 5. As a result, it is necessary to change the width of the opening frame 6 by the thickness of the auxiliary board 4. In an apartment house or the like, an opening frame that is pre-cut and has a fixed size is used, and an opening frame that can be adjusted according to the wall thickness is not used. Therefore, if the auxiliary board 4 is additionally attached as in this embodiment, the opening frame of this portion is used. There is no need to change the size by 6, which is desirable in terms of member management.

  Here, in this embodiment, the surface gypsum board 2 is 12.5 mm thick, and the auxiliary board 4 is 9.5 mm thick gypsum board. And the surface gypsum board 2 is fixed to the column 1 using a screw body (not shown), and the auxiliary board 4 is similarly attached to the surface gypsum board 2 using a screw body at an appropriate interval. The opening 5 is provided with an opening frame 6 for covering the end of the partition wall. The opening frame 6 is preliminarily cut with a decorative board material and fixed to the opening 5 since the thickness of the partition wall is determined in advance as described above, particularly in a standard house such as an apartment house.

  The surface gypsum board 2 may be a single gypsum board that is continuous from the floor to the ceiling, or may be a smaller gypsum board, and another gypsum board may be used for the shortage. The same applies to a gypsum board used as the auxiliary board 4. And there is no particular direction for attaching the gypsum board, and it may be used sideways. In addition, repair the abutting part with a gap-like putty so that it does not appear on the surface of the cloth.

  In addition, the thickness of the gypsum board shown here is an example.For example, when the thickness is changed, the inter-room sound pressure level difference characteristic unique to the gypsum board changes, but by using this, by adjusting the thickness, The inter-room sound pressure level difference characteristic of the entire partition wall structure can be adjusted. In addition to the gypsum board, the auxiliary board 4 may be a board such as a lead sheet in which the coincidence frequency region is higher than the coincidence frequency region of the surface gypsum board 2.

  In addition, the surface gypsum board 2 and the auxiliary board 4 are not necessarily attached to the surface gypsum board 2 by the attaching means of only the screw body, but may be attached using, for example, an adhesive. Is not a method in which the entire surface is applied and these are bonded together, but as shown in FIG. 6 as an example in the case of using a wall panel, the area where the adhesive 9 is applied is reduced, The gypsum board 2 and the auxiliary board 4 are left with many unbonded portions so that they are not completely integrated.

  This is because, when the two are completely integrated, the inter-room sound pressure level difference characteristic is no longer shown as a single gypsum board. In the coincidence frequency region of the surface gypsum board 2, the auxiliary board 4 is not in the coincidence frequency region, and can be complemented so that the pressure level difference characteristic can be utilized, and the auxiliary board 4. In the coincidence frequency region, the effect that the coincidence frequency region of the surface gypsum board 2 is out of the complement is obtained.

  For this reason, when a gypsum board having the same thickness is simply pasted, the inter-room sound pressure level difference increases and the sound insulation characteristics are improved, but the coincidence frequency region itself does not change. Therefore, as a whole, the sound insulation characteristics of the partition wall structure can be improved while maintaining the same frequency range, but conversely, the inter-room sound pressure level difference at the coincidence frequency is much worse than when one sheet is used. However, when the auxiliary board 4 having a different thickness is used as described above, it is possible to prevent the deterioration of the inter-room sound pressure level difference characteristic in the coincidence frequency region.

  In this embodiment, a gypsum board that is an auxiliary board 4 thinner than the surface gypsum board 2 in which the coincidence frequency region has a higher frequency than the surface gypsum board 2 is used. Therefore, conversely, when using a gypsum board that is thicker than the surface gypsum board 2 and the auxiliary board 4 whose coincidence frequency region is lower than the surface gypsum board 2, the coincidence frequency transitions to a low frequency. As a result, it becomes difficult to exhibit a desired inter-room sound pressure level difference characteristic.

  And the measurement result in the example using the wall panel 8 is shown in FIG. This consists of a normal partition wall structure (square plot), a partition wall structure (triangle plot) with an additional 12.5 mm thick gypsum board, and an auxiliary 9.5 mm thick gypsum board. This is a result of measuring and comparing the inter-room sound pressure level difference between the partition wall structures (diamond plots) to which the board 4 is additionally attached. The wall panel 8 is configured by providing a 12.5 mm surface gypsum board 2 on both sides of the frame. The measurement was performed based on the method defined in JIS A 1417. In addition, the inter-room sound pressure level difference characteristic predicted by only one gypsum board is shown as a schematic line.

  Looking at this, the frequency of each coincidence is almost the same in the partition wall structure with 12.5mm gypsum board, which is the same thickness as the surface gypsum board 2, and the sound pressure level difference between the rooms as a whole. Although the performance was improved, the drop in the difference in the sound pressure level between rooms at the same frequency has increased. On the other hand, the partition wall structure, which is thinner than the surface gypsum board 2 and bonded with additional 9.5 mm gypsum board, can improve the inter-room sound pressure level difference, and can shift the coincidence frequency to a higher frequency range. Yes. In addition, the drop in the sound pressure level difference between rooms in the coincidence frequency region is smaller than when using a gypsum board having the same thickness. This means that the sound insulation characteristics in the audible frequency band for measuring the sound insulation characteristics of the partition wall structure can be further improved.

  Next, an example of a partition wall structure using the wall panel 8 as shown in FIG. 2 is shown.

  In this example, as in the case of the conventional method, a column body 1 standing between the floor and the ceiling and arranged in parallel to each other, and a plurality of column bodies 1 are provided on both sides of the column body 1, and between the floor and the ceiling. A partition wall body 3 composed of a surface gypsum board 2 that closes the wall and a surface gypsum board 2 of the partition wall body 3 so as to cover a predetermined range of the surface gypsum board 2 on one side. A partition wall structure comprising an auxiliary board 4 thinner than the surface gypsum board 2, and a wall panel frame configured by adhering the column 1 to the both sides of the frame body 7 with a surface gypsum board The shape is used as the vertical member 7 a of the body 7. The auxiliary board is a gypsum board thinner than the surface gypsum board 2 and is provided so as to cover the vertical butt portion 81 of the adjacent surface gypsum board.

  Thus, the structure is the same as the partition wall structure according to the conventional method shown in FIG. 1 except that the column body 1 is configured as the vertical member 7a of the frame body 7 of the wall panel 8 as shown in FIG. Therefore, the same characteristic can be obtained for the inter-room sound pressure level difference characteristic. Other configurations such as the opening 5 in FIG. 2 are the same as those in FIG. 3 and 6 are views using the wall panel 8 as shown in the figure, and the explanation given above is applied as it is.

  In this wall panel 8, as shown in FIG. 5, the frame body 7 is composed of vertical members 7a and cross members 7b, and the vertical bars 7c for reinforcing the surface gypsum board 2 are composed as shown in the figure. . Note that the wall panel 8 itself may be provided on only one side of the frame 7 in advance or on both sides. In the case of FIG. 5, the surface gypsum board 2 is provided on both sides. This difference is mainly due to the presence / absence of construction of wiring equipment or the like at the site. A plurality of wall panels 8 are continuously erected at the construction site, and finally the surface gypsum board 2 is formed on both surfaces of the frame 7. It becomes a partition wall in the provided state.

  The obtained inter-room sound pressure level difference characteristic is the same as that shown in FIG. In addition, since the construction itself of the wall panel 8 is performed by a conventional method that has been conventionally performed, description thereof is omitted.

It is plane sectional drawing which shows the partition wall structure used as the Example by the conventional construction method of this invention. It is a plane sectional view showing the partition wall structure by the wall panel construction method. It is a perspective view of the partition wall structure by the same wall panel construction method.
