[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sound insulation structure for a moving wall, and is particularly targeted at sound insulation of a pressure contact member and a shield member.

[0002]

[Prior art]

 Partitions are used to partition large spaces into appropriate sizes. Various types of partitions are known, but one is a partition that is constructed by fixing the panel side edge to vertically standing studs with a certain interval, and a suspension car at the upper end of the moving wall. There are partitions that are attached and hung on rails installed on the ceiling, and further called low partitions, such as partitions with a low height.

Among the various types of partitions described above, the moving wall is used in order to freely change the size of the space to be partitioned. As is well known, the moving wall is provided with a suspension car at its upper end so that the suspension car can move along a rail arranged on the ceiling, and therefore the moving wall can also move to a predetermined place. Can be done. Then, the space is partitioned by arranging it at a predetermined place, and on the contrary, in order to restore the partitioned space, the array of the moving walls may be disassembled and stored in the storage part.

By the way, the moving wall is moved to a predetermined place and arranged, but since it is not stable in a state where it is simply arranged, the pressure contact member is extended to prevent the pressure wall from contacting the floor surface and the ceiling so as not to move. It will be fixed. The pressure contact member is provided at the upper and lower ends of the moving wall, and the leading moving wall that abuts the wall surface of the room is provided with a shield member protruding from the side end. These shield members and pressure contact members allow stable positioning without leaving a gap between the moving walls and between the floor surface and the ceiling.

The moving walls are not only stably arranged in a fixed position without a gap in this way, but also have a sound insulation property today. Although the moving wall body has relatively high sound insulation, sound is often transmitted from the pressure contact member or the shield member. FIG. 4 shows a cross section of a conventional floor pressure welding member. The pressure contact member (a) moves up and down by being installed in the frame (b) having a gate-shaped cross section, but the sound is transmitted through the road of (a) or the road of (b). FIG. 5 shows a conventional shield member (c), but the shield member (c) is slidable inside the side frame (d). In this case, as in the case of the pressure contact member (a), the sound is transmitted through the road of (c) or the road of (d).

[0006]

[Problems to be solved by the present invention]

 As described above, the sound insulation of the conventional moving wall has the above problems. The problem to be solved by the present invention is this problem, and provides a sound insulation structure for a moving wall in which the sound insulation of the upper and lower pressure contact members and the shield member is improved.

[0007]

[Means for Solving the Problems]

 The sound insulation structure of the moving wall according to the present invention is characterized by improving the sound insulation of the pressure contact member for fixing the moving wall and the shield member for contacting the wall surface of the room. Therefore, the press-contacting member has a double-structured hollow body with a leg provided with a sealing material, and is configured to attenuate the sound passing through the path shown in FIG. 4 (a). Although the leg has a double structure, an air layer is provided between the legs, but the air layer may be filled with urethane or the like. That is, the sound energy is absorbed and attenuated by the change of the transmission medium. Then, a seal material is interposed to eliminate a gap between the pressure contact member and the frame in which the pressure contact member is installed.

Similarly, one of the shield members is also provided with a sealing material for eliminating a gap between the shield member and a frame in which the shield member is internally mounted, and a gypsum board is attached to the inner surface of the arm or the arm is doubled. A hollow body having a structure and a space having a double structure are filled with urethane or the like. Even in this case, the structure is such that the sound energy is absorbed by changing the sound transmission medium. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 is an embodiment showing a cross section of a lower press contact member of a moving wall. The moving wall is formed by attaching panels 1 and 1 to a frame serving as a skeleton, and a lower frame 3 is provided below the reinforcing bar 2, and the lower frame 3 connects the lower edge of the moving wall. Is forming. As shown in the figure, the lower frame 3 is a long member having a gate-shaped cross section, and the pressure contact member 5 is installed in the space 4, and the pressure contact member 5 can move up and down. The vertical movement of the pressure contact member is performed by a pressure contact device (not shown) provided in the space 4.

The pressure contact member 5 is a long member having a predetermined cross-sectional shape, and has two legs 6 and 6 formed below and two arms 7 and 7 formed above. A seal member 8 is fixed to the lower end of the leg 6, and another seal member 9 is fixed to the tip of the arm. The seal member 8 is pressed against the floor surface by the pressure contact member descending, and the seal member 9 at the tip of the arm contacts the side piece 10 of the lower frame 3 to eliminate the gap. Here, the sealing material 9 is not necessarily limited to the arm tip. The leg 6 is a double-structured hollow body having a cavity 11 formed therein.

By the way, when the sound passes through the route (a), since the leg 6 has the double structure having the cavity 11, the number of times the sound transmission medium changes becomes larger than that in the conventional case. The sound energy is absorbed and attenuated every degree. Further, the sound that enters the space 4 of the lower frame 3 and is transmitted is blocked by the seal material 9 at the tip of the arm. Furthermore, the cavity 11 of the leg 6 may be filled with urethane, and the damping effect is further improved by filling the urethane. The upper end of the moving wall can be constructed with a structure similar to this.

FIG. 2 shows an embodiment showing the shield member 12. The shield member 12 functions so as to contact the end rails provided on the wall surface of the room so as to eliminate the gap, and a projecting device for projecting the shield member 12 outward is provided on the side frame 13. It is installed in the digit space 14. The present invention does not limit the structures of the overhanging device and the pressure welding device. By the way, the shield member 12 has two arms 15 and 15, a sealing material 16 is fixed to the ends of the arms, and the sealing material 16 contacts the side piece of the side frame 13 to eliminate a gap. .

A gypsum board 17 is attached to the inside of the arm 15, and a predetermined space 18 is left between the gypsum boards 17, 17. Therefore, when sound is transmitted through the route of (c), the sound transmission medium changes in the order of aluminum plate ⇒ gypsum board ⇒ air layer ⇒ gypsum board ⇒ aluminum plate, and the sound energy is changed each time. It is absorbed and attenuated. Also in the case of this shield member 12, the arm 15 may be a hollow body having a double structure having a cavity 19 as shown in FIG. 3, or the cavity 19 may be filled with urethane.

On the other hand, the sound transmitted through the gap between the shield member and the side frame is blocked by the seal member 16. As described above, the following effects can be obtained by configuring the moving wall pressure contact member and the shield member according to the present invention as described above.

[0015]

[Effect of device]

 In the upper and lower pressure contact members of the present invention, the legs are formed as a double-structured hollow body having a cavity, so that the sound transmitted through the legs is absorbed and attenuated because the transmission medium changes. Particularly, it is more effective if the cavity is filled with urethane or the like. Further, since the sealing material is fixed so that no gap remains between the pressure contact member and the frame in which it is installed, sound leakage from this portion is also prevented. Similarly, in the case of a shield member, the sound transmission can be suppressed by changing the sound transmission medium by attaching a plaster board to the arm or by using a double structure, and a high sound insulation effect can be obtained. can get.
