Are arranged and pressed to each other through the spacer member, and a gap corresponding to the thickness of the spacer member is provided between the outer frame members .

By connecting between the outer frame members of each frame via the spacer members, it is possible to prevent the outer frame members from coming in contact with each other and rubbing, and it is possible to connect the spacer members made of low friction material and the outer frame members. Because of the contact, the generation of frictional noise can be suppressed.
In this case, when expansion or contraction occurs in each frame member due to the influence of heat, humidity, or the like, one frame member of the other frame member is connected to the connection portion between the vertical frame member and the horizontal frame member in each frame. The frame member is pressed and a force is applied in the pressing direction. That is, in the outer frame member, the outer frame member is pressed by the frame member orthogonal to the outer frame member, and a force is applied in the pressing direction. Even in this case, the outer frame is extended on the extension of the orthogonal frame member Since the spacer members are disposed between the members, the contact between the outer frame members can be reliably prevented, and the generation of frictional noise can be suppressed.
In addition, it can reduce in weight by replacing with the thing of metal as these frame members, and using a wood-based material, and construction | assembly work of an assembly-type soundproof room etc. can be made easy.

  In the frame connecting structure of the present invention, it is preferable that the outer frame members be fastened by a fastening member, and the spacer member be disposed at the fastening portion.

  The frames are finally laid in the living room, etc., and the pressed state is maintained at the time of use, but the assembly workability is improved by fastening with the fastening members. It can be done. And, when both outer frame members are fastened by the fastening member in this way, interposing the spacer member between the outer frame members at the fastening portion prevents the contact between the outer frame members. And the generation of frictional noise can be suppressed.

In the frame connection structure of the present invention, the spacer member may be formed of a foamed resin.
Since the buffer effect can be obtained by forming the spacer member with the foamed resin, the suppression effect of the frictional noise can be further enhanced.

  Then, the frames 1A and 1B configured in this way are placed on the existing floor in a state where three sheets are arranged side by side, and as shown in FIGS. 7 to 9, between the frames 1A and 1B. The connection-side vertical frame members 11B of the frames 1A and 1B are connected with each other with the spacer member 22 made of a low friction material interposed therebetween. The connection work of the frames 1A and 1B is performed before the floor panel 4 is provided, and is easy because it is a work in the state of the frame. The three frames 1A and 1B are connected to each other by connecting the outer frame members disposed on the outer peripheral portions of the respective frames 1A and 1B, and in the present embodiment, connecting the connection-side vertical frame members 11B to each other. It is done by

It is connected by being concluded. The spacer member 22 is also disposed between the connection-side vertical frame members 11B of the fastening portion 30 fastened by the fastening member 31. In this case, both connection side vertical frame members 11B are pressed and fastened to each other by the fastening member 31. Since the spacer members 22 are interposed between the connection side vertical frame members 11B in the fastening portion 30, the two are arranged side by side. A gap g3 for the thickness of the spacer member 22 is secured between the connection-side vertical frame members 11B arranged in the above.

  The spacer member 22 is provided in a sheet shape having a thickness of 1 mm, and a member with low friction resistance having a dynamic friction coefficient of about 0.1 to 0.7 can be used, and the shape is not particularly limited. For example, a foamed resin such as foamed polyethylene referred to as "verpolene" can be suitably used.

By connecting the connecting vertical frame members 11B of the frames 1A and 1B via the spacer members 22 made of such a low friction material, the connecting vertical frame members 11B are prevented from coming in contact with each other and being rubbed. Since the spacer member 22 made of a low friction resistance material is in contact with the connecting side vertical frame member 11B, the generation of frictional noise due to the spacer member 22 and the connecting side vertical frame member 11B rubbing is prevented. be able to.

Since the spacer member 22 is disposed between the members 11B, the gap g3 is secured. Therefore, contact between the connecting side vertical frame members 11B can be reliably prevented, and the generation of frictional noise can be suppressed.
Further, as described above, even if the frame members 11 and 12 are formed of wood-based materials and moisture absorption and drying are repeated depending on the season and the room environment, the connection side vertical frame members 11B are in contact with each other. As this is prevented, the generation of frictional noise can be prevented.

Furthermore, as in the case of the floor frame 1 of the present embodiment, the frames 1A and 1B can be handled integrally by fastening the frames 1A and 1B with the fastening members 31, thereby improving the assembly workability. be able to. Further, in this case, by interposing the spacer member 22 between the both connection side vertical frame members 11B also in the fastening portion 30, the contact between the both connection side vertical frame members 11B in the fastening portion 30 is surely prevented. And the generation of frictional noise can be suppressed.
The spacer member 22 is added to an extension of the inner horizontal frame member 12B orthogonal to the connection-side vertical frame member 11B of the frames 1A and 1B and between the connection-side vertical frame member 11B of the fastening portion 30 by the fastening member 31. It can also be disposed at another portion between the connecting side vertical frame members 11B.

  Further, when the spacer member 22 is formed of a foamed resin such as foamed polyethylene, both of the sound propagation preventing effect and the impact alleviating effect can be obtained by the foamed portion, so friction noise between the connection side vertical frame members 11B The suppression effect can be further enhanced.

  In addition, as shown in FIG. 10, since each frame 1A, 1B is finally installed in a living room and combined with other members, the pressed state is maintained during use. . For this reason, in the frame connecting structure of the present invention, it is not necessary to fasten the connecting vertical frame members 11B with each other by the fastening members 31 after the assembly is completed. Therefore, it is sufficient if the arrangement and connection between the frames 1A and 1B can be maintained during the assembly work of the floor frame 1, and the assembly can be performed using a simple fastening member such as a clip or a tape. . Furthermore, the fastening member may be temporarily used and fastened during the assembly operation of the floor frame 1 or may be removed after the assembly is completed.

And, on the floor frame 1 configured in this manner, the wall panel 5 is mounted on the wide outer circumferential side vertical frame member 11A and the outer circumferential side horizontal frame member 12A forming the outer circumferential portion of the floor frame 1 By placing the floor panel 4 inside and installing the ceiling panel 6, the soundproof room unit 2 is constructed.
The use of wood-based materials as the frame members 11 and 12, the connection member 13 and the face members 14A and 14B can reduce the weight and facilitate the construction work of the assembly type soundproof room unit 2. Can.
