Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the window fitting structure of the soundproof room in Patent Document 1 is not for improving the appearance of the gap portion at the location where the opening formed in the wall of the existing room and the opening formed in the wall of the separately installed room overlap in a structure where a separate room is constructed in the existing room to make it a soundproof room.

[0005] The object of this invention is to provide a gap-sealing structure for overlapping openings that can improve the appearance of the gap at the point where an opening in the wall of an existing room and an opening in the wall of the separately installed room overlap, even in a structure where a separate room is constructed within an existing room to make it a soundproof room. [Means for solving the problem]

[0006] The gap-sealing structure for overlapping openings of this invention solves the above problem by having a second room constructed inside a first room, and having an opening in the wall of the first room and an opening in the wall of the second room overlapping. A sealing frame material having a fixing piece and a sealing piece is positioned near the starting point of the gap between the two walls, which is located on the opening side. The sealing frame material is fixed by the fixing piece to either the wall side of the first room or the wall side of the second room, and the sealing piece is positioned non-contact with the other wall side of the first room or the wall side of the second room, sealing the gap between the two walls or the starting point of the gap.

[0007] With the above configuration, the sealing piece of the sealing frame material seals the gap between the two walls or the beginning of the gap, preventing the back of the gap between the two walls from being visible and improving the appearance of the gap. Moreover, since the sealing piece is located non-contact with the other side of the wall of the first room or the wall of the second room, it is possible to suppress solid-borne sound transmission from the wall of the first room to the wall of the second room, and from the wall of the second room to the wall of the first room, caused by the sealing frame material.

[0008] In the above configuration, another sealing frame material is placed near the starting point of the gap, and the fixing piece of this other sealing frame material is fixed to the wall side of the first room or the other wall side of the second room, and the sealing piece of the other sealing frame material is positioned non-contact with either the wall side of the first room or the wall side of the second room and the sealing frame material, and may seal the gap between the two walls or the starting point of the gap. With this, the sealing pieces of the sealing frame material and the other sealing frame material will overlap in the gap between the two walls or the starting point of the gap, so it is possible to prevent the gap between the sealing piece and the wall from being visible.

[0009] Furthermore, the overlapping opening gap-sealing structure of this invention is an overlapping opening gap-sealing structure in which a second room is constructed inside a first room, and an opening opened in the wall of the first room and an opening opened in the wall of the second room are located in an overlapping position. A sealing frame material having a fixing piece and a sealing piece is positioned near the starting point of the gap between the two walls, located on the opening side. The sealing frame material is fixed by the fixing piece to either the wall side of the first room or the wall side of the second room. The sealing piece is made of vibration-damping material and is positioned in contact with the other wall side of the first room or the wall side of the second room, sealing the gap between the two walls or the starting point of the gap.

[0010] With the above configuration, the sealing piece of the sealing frame material seals the gap between the two walls or the beginning of the gap, preventing the back of the gap between the two walls from being visible and improving the appearance of the gap. The sealing piece is located in contact with the other side of the wall of the first room or the wall of the second room, and since it is made of vibration-damping material, it can suppress solid-borne sound transmission from the wall of the first room to the wall of the second room, and solid-borne sound transmission from the wall of the second room to the wall of the first room, caused by the sealing frame material.

[0011] In the above contact configuration, the sealing frame material may also be provided with other sealing pieces located in a non-contact position with respect to the other side of the wall of the first room or the wall of the second room, positioned in front of the sealing piece. This allows the sealing piece made of vibration-damping material to be made less visible by the other non-contact sealing piece.

[0012] In these configurations, the opening in the wall of the second room may be larger in both length and width than the opening in the wall of the first room. This makes it possible to omit on-site measurements to ensure that the opening in the wall of the second room is the same size as the opening in the wall of the first room when constructing the second room within the first room to make it a soundproof room. However, if the sizes of the two openings are different in this way, the gap will be more noticeable, but since the sealing piece closes the gap between the two walls or the beginning of the gap, the appearance of the gap between the two walls can be improved.

[0013] In a configuration that does not include a sealing piece made of the above-mentioned vibration-damping material, a sound-reducing material that reduces sound transmission may be placed in the gap between the two walls at a position hidden by the sealing piece. This allows the sound that passes through the gap between the two walls to be reduced by the sound-reducing material. [Effects of the Invention]

[0014] With the present invention, even in a structure where a separate room is constructed inside an existing room to make it a soundproof room, the appearance of the gap at the point where the opening in the wall of the existing room and the opening in the wall of the separate room installed inside the existing room overlap can be improved.

[Figure 5] This is an explanatory diagram showing another example of the gap-sealing structure for overlapping openings in the embodiment. [Figure 6] This is an explanatory diagram showing another example of the gap-sealing structure for overlapping openings in the embodiment. [Modes for carrying out the invention]

[0016] Embodiments of this invention will now be described based on the attached drawings. As shown in Figure 1(A), the overlapping opening gap sealing structure 10 of the embodiment can be applied, for example, to a room structure 8 in which a second room 2 is newly constructed as a soundproof room inside a first room 1 which is an existing room.

[0017] A rectangular opening 12 is provided in the wall 11 of the first room 1, and a rectangular opening 22 is provided in the wall 21 of the second room 2. These openings 12 and 22 are located in overlapping positions. Furthermore, the vertical and horizontal dimensions of the opening 22 in the second room 2 are larger than those of the opening 12 in the first room 1. There are no particular restrictions on the extent of these dimensions, and since the vertical and horizontal dimensions of the opening 12 in the first room 1 are predetermined to be several standard sizes, there is no need to have too many variations in the vertical and horizontal dimensions of the opening 22.

[0018] As shown in Fig. 1(B) as well, for example, a window 13 is fitted into the opening 12, and a window 23 with longitudinal and lateral dimensions larger than those of the window 13 is fitted into the opening 22. Further, for example, a gap G of about 5 cm to 20 cm is formed between the above two walls 11 and 21, and a gap start point G1 is located on the opening 12, 22 side of this gap G. The gap start point G1 exists in a square frame shape on the peripheral side of the openings 12 and 22. If the gap blocking structure 10 of the overlapping openings is omitted, the back side of the gap G will be visible from this gap start point G1 in the left - right direction and the up - down direction.

[0019] The gap blocking structure 10 of the overlapping openings includes, for example, as shown in Fig. 2, a blocking frame member 3 and a blocking frame member 4 different from this blocking frame member 3. The blocking frame members 3 and 4 are made of a resin plate, a metal plate, a wooden plate, or the like.

[0020] The blocking frame member 3 has a fixing piece part 31 and a blocking piece part 32, and the cross - section of the blocking frame member 3 is L - shaped. The blocking frame member 3 is arranged near the gap start point G1 in the gap G between the two walls 11 and 21, and the fixing piece part 31 is fixed to the wall 11 side (the end part on the window 13 side) of the first room 1 by screws or the like. In this fixed state, the blocking piece part 32 is positioned in a non - contact manner with respect to the wall 21 side of the second room 2 and blocks the inside of the gap G between the two walls 11 and 21.

[0021] The blocking frame member 4 has a fixing piece part 41 and a blocking piece part 42, and the cross - section of the blocking frame member 4 is substantially Z - shaped. The blocking frame member 4 is arranged near the gap start point G1 in the gap G between the two walls 11 and 21, and the fixing piece part 41 is fixed to the wall 21 side (the window frame of the window 23) of the second room 2 by screws or the like. In this fixed state, the blocking piece part 42 is positioned in a non - contact manner with respect to the wall 11 side of the first room 1 and the blocking frame member 3 and blocks the inside of the gap G between the two walls 11 and 21.

[0022] Furthermore, a sound-reducing material 5 is arranged in a frame shape within the gap G between the two walls 11 and 21, in a position hidden by the sealing pieces 32 and 42, to reduce sound transmission. This sound-reducing material 5 is, for example, adhesively fixed to the back side of the sealing piece 32 of the sealing frame material 3, and is positioned so as not to come into contact with the wall 21. The sound-reducing material 5 is, for example, a sound-absorbing material made of high-fiber density or low-fiber density glass wool. Note that if the sound-reducing material 5 is made of low-fiber density glass wool, even if it is set in a state where it comes into contact with the two walls 11 and 21, solid-borne sound transmission between the two walls 11 and 21 is prevented.

[0023] With the above configuration, the blocking piece 32(42) of the blocking frame material 3(4) is located within the gap G between the two walls 11 and 21, preventing the back of the gap G from being visible and improving the appearance of the gap G and the gap's starting point G1. Moreover, since the blocking piece 32 of the blocking frame material 3 is located without contact with the wall 21 of the second room 2, it is possible to suppress solid-borne sound transmission from the wall 11 of the first room 1 to the wall 21 of the second room 2, and from the wall 21 of the second room 2 to the wall 11 of the first room 1, caused by the blocking frame material 3.

[0024] Furthermore, in this embodiment, another sealing frame material 4 is positioned near the gap start point G1, and the fixing piece 41 of this sealing frame material 4 is fixed to the wall 21 side of the second room 2, and the sealing piece 42 of the sealing frame material 4 is positioned within the gap G, without contact with the wall 11 side of the first room 1 and the sealing frame material 3, and overlapping the sealing piece 32, so that the back side of the gap G can be more reliably prevented from being seen.

[0025] Furthermore, since the opening 22 in the wall 21 of the second room 2 is larger in both length and width than the opening 12 in the wall 11 of the first room 1, in construction to build the second room 2 within the first room 1 to create a soundproof room, it becomes possible to omit on-site measurements to make the opening 22 in the wall 21 of the second room 2 the same as the opening 12 in the wall 11 of the first room 1. When the sizes of the openings 12 and 22 are different in this way, the gap G and the gap start point G1 become more noticeable, but since the sealing piece 32 (42) is located within the gap G, the appearance of the gap G and the gap start point G1 can be improved. Note that it is acceptable for the gap between sealing pieces 32 and 42 to be somewhat large, so if the depth (width) of the sealing piece 32 is made somewhat large, many sealing pieces of the same type with an extended depth can be used.

[0026] Furthermore, since the sound-reducing material 5 is positioned within the gap G and hidden by the sealing piece 32 (42), the transmission of sound passing through the gap G can be reduced by the sound-reducing material 5.

[0027] In the example above, both the blocking frame material 3 and the blocking frame material 4 are provided, but the configuration is not limited to this, and it may also consist of only one of the blocking frame material 3 or the blocking frame material 4. Furthermore, if only the blocking frame material 4 is provided, the sound reduction material 5 can be fixed by adhesive to the back side surface of the blocking piece 42 of the blocking frame material 4.

[0028] Figure 3 shows another example of the overlapping opening gap sealing structure 10. This other example of the overlapping opening gap sealing structure 10 includes a sealing frame member 3A. This sealing frame member 3A includes a sealing piece 32A made of a frame-shaped vibration-damping material and the sealing piece 32. The fixing piece 31 of the sealing frame member 3A extends to a position further inside the gap G than the sealing piece 32, and the sealing piece 32A is located at the extended end of this fixing piece 31.

[0029] The other end of the sealing piece 32A is pressed against the wall 21 of the second room 2, so that no gap is formed between the other end of the sealing piece 32A and the wall 21. The vibration damping material is, for example, a bellows-shaped member (spring-shaped member) made of rubber or metal (for example, with a plate thickness of about 0.5 mm), and is positioned in contact with the two walls 11 and 21. This sealing piece 32A reduces the transmission of sound passing through the gap G, while also preventing solid-borne sound between the two walls 11 and 21.

[0030] In this case, if the sealing frame material 4 shown in Figure 2 is not present, the inside of the gap G can be seen through the gap between the sealing piece 32 and the wall 21. However, since no gap is formed between the other end of the sealing piece 32A and the wall 21, the inside of the gap G cannot be seen.

[0031] In the configuration shown in Figure 3, the blocking piece 32 can be omitted, and the configuration can consist only of a blocking piece 32A made of vibration-damping material. However, including the blocking piece 32 has the advantage of making the blocking piece 32A made of vibration-damping material less visible.

[0032] Figure 4 shows another example of the overlapping opening gap sealing structure 10. This other example of the overlapping opening gap sealing structure 10 includes a sealing frame member 4A. The sealing frame member 4A has a sealing piece 42A made of a cloth-like vibration-damping material. One end of the sealing piece 42A is fixed to a fixing piece 41, and the other end of the sealing piece 42A is fixed to the wall 11 of the first room 1 with screws or the like. The cloth-like vibration-damping material is, for example, a soundproofing sheet and is positioned in contact with the two walls 11 and 21. With this configuration, the sealing frame member 4A seals the gap G between the two walls 11 and 21 without any gaps because the sealing piece 42A is positioned in contact with the wall 11 side of the first room 1. Even if the blocking piece 42 comes into contact with both walls 11 and 21, since the blocking piece 42A is made of vibration-damping material, solid-borne sound does not occur between the two walls 11 and 21.

[0033] Figure 5 shows another example of the overlapping opening gap-closing structure 10. This other example of the overlapping opening gap-closing structure 10 comprises a closing frame member 3B and a closing frame member 4B. The closing frame member 3B comprises a plurality of closing pieces 33 positioned at predetermined intervals in the direction toward the back of the gap G. The closing frame member 4B also comprises a plurality of closing pieces 43 positioned at predetermined intervals in the direction toward the back of the gap G and offset from the closing pieces 33.

[0034] With the sealing frame members 3B and 4B fixed by the fixing pieces 31 and 41 respectively, a meandering path is formed within the gap G by the multiple sealing pieces 33 and 43. The multiple sealing pieces 33 and 43 that form this meandering path form a sound-reducing material 5A that reduces the transmission of sound passing through the gap G.

[0035] Figure 6 shows another example of the overlapping opening gap sealing structure 10. In this other example of the overlapping opening gap sealing structure 10, when constructing a second room 2 within a first room 1 to make it a soundproof room, on-site measurements are taken to make the vertical and horizontal dimensions of the opening 22 to be made in the wall 21 of the second room 2 the same as the vertical and horizontal dimensions of the opening 12 to be made in the wall 11 of the first room 1. In such overlapping openings, the sealing frame material 3C and sealing frame material 4C are fixed by fixing pieces 31 and 41, respectively.

[0036] The fixing piece 31 of the sealing frame material 3C is fixed to the wall 11 side (window frame of window 13) of the first room 1 with screws or the like, and the sealing piece 32 of this sealing frame material 3C is positioned non-contact with the wall 21 side (window frame of window 23) of the second room 2 and the sealing frame material 4C while sealing the gap start point G1. Similarly, the fixing piece 41 of the sealing frame material 4C is fixed to the wall 21 side (window frame of window 23) of the second room 2 with screws or the like, and the sealing piece 42 of this sealing frame material 4C is positioned non-contact with the wall 11 side (window frame of window 13) of the first room 1 and the sealing piece 32 of the sealing frame material 3C while sealing the gap start point G1.
