Description

[Technical field]

[0001] The present invention relates to a wall soundproofing device provided between left and right building frames and a soundproofing structure for a joint. [Background technology]

[0002] In the past, buildings constructed near airports or factories have generally been fitted with soundproofing materials to block out noise generated by these facilities. However, in areas connecting the spaces between separate buildings on the left and right, or in walkways, etc., a distance has been set that takes into account the shaking of the buildings, so general soundproofing materials could not be installed.

[0003] As a soundproofing device installed between two structures, there is described an expansion joint that also has soundproofing performance, the expansion joint comprising: "an expansion joint installed in the gap between the two skeletons of a structure, the expansion joint comprising at least two fire-resistant sheets; a plate-shaped vacuum insulation material sandwiched between the at least two fire-resistant sheets and having a shorter widthwise length than the at least two fire-resistant sheets; a retaining member that holds in an overlapped state at least two of the fire-resistant sheets extending outward from the widthwise ends of the vacuum insulation material in a laminate formed by overlapping the fire-resistant sheets and the vacuum insulation material; and a support member that supports, via the retaining member, the portions of the at least two fire-resistant sheets in the overlapped state in the laminate that are held by the retaining member to the skeleton" (Patent Document 1).

[0004] However, to achieve a soundproofing effect, it is necessary to efficiently absorb and reflect sound from outside, and a flexible sheet alone like this is unable to efficiently reflect sound, making it impossible to achieve a sufficient soundproofing effect.

[0017] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, the left-right direction, the top (top of the drawing) and the bottom (bottom of the drawing) directions are based on Fig. 1. The front (bottom of the drawing) and rear (top of the drawing) directions are based on Fig. 2.

[0018] In addition, in the present invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc. in which a joint plate can be installed, and the term "entrance / exit" refers not only to an entrance / exit with a door or gate, but also to a passageway through which people, vehicles, etc. can pass.

[0019] In a first embodiment for carrying out the present invention shown in Figs. 1 to 10, reference numeral 1 denotes a wall soundproofing device that is installed in a joint portion 2 between one body 3 and another body 4. This wall soundproofing device 1 is composed of one soundproof panel 5 having one mounting base end attached to one frame 3, the other soundproof panel 6 having the other mounting base end attached to the other frame 4, one or more intermediate soundproof panels 7 arranged to overlap face-to-face between parts of the wall surface portions of the one soundproof panel and the other soundproof panel, support means 8 for supporting the intermediate soundproof panel and positioning it at a predetermined position, and abutment means 9 for constantly abutting the adjacent soundproof panels so that no gap is generated between the parts of the wall surface portions of the adjacent soundproof panels. The one soundproof panel 5, the other soundproof panel 6, and the intermediate soundproof panel 7 are composed of a panel body 10 and a soundproof member 11 arranged to cover at least one side of the panel body, and during an earthquake, the overlapping width of the facing wall surface portions of the one soundproof panel 5, the other soundproof panel 6, and the intermediate soundproof panel 7 changes, absorbing the shaking caused by the earthquake.

[0020] Each of the constituent members will now be described in detail. As shown in Fig. 3 and Fig. 4, the first soundproof panel 5, the second soundproof panel 6, and the intermediate soundproof panel 7 each include a panel body 10 and a soundproof member 11 provided so as to cover at least one side surface (preferably the front and back surfaces) of the panel body 10. In this embodiment, the soundproof member 11 is provided over the entire outer side surface.

[0021] The panel body 10 is a substantially rectangular plate material, and has a sheet-like soundproofing material 11 fixed to the entire outer surface.

[0022] The soundproofing material 11 may be, for example, a sheet-like lead, but it is preferable to use a soft soundproofing sheet containing metal powder or a high-density filler. In this embodiment, the soundproofing material 11 is provided only on one side of the panel body 10 so that the soundproofing material 11 can cover the joints 2 without any gaps, but the soundproofing material 11 may be provided on all sides.

[0023] One soundproof panel 5 is rotatably mounted on a wall surface 3a of one body 3 or a wall surface 4a of the other body 4 via a hinge member 12, and the other soundproof panel 6 is also rotatably mounted on a wall surface 4a of the other body 4 or a wall surface 3a of one body 3 via a hinge member 12.

[0024] It is desirable to fill the gap between the one soundproof panel 5 and the other soundproof panel 6 and the wall surfaces of the left and right frames 3, 4 with a sealant 23 or the like having a soundproofing effect. By filling the gap with such a sealant, the soundproofing effect can be further improved.

[0025] The intermediate soundproof panel 7 is supported by a support means 8 provided between one body 3 and the other body 4, and this support means 8 ensures that the intermediate soundproof panel 7 is always positioned in such a way that its both end sides are approximately abutting one soundproof panel 5 and the other soundproof panel 6.

[0026] The support means 8 is composed of a base member 13 attached directly or indirectly to the wall surface 3a of one body 3 or the wall surface 4a of the other body 4, a pantograph-like link member 14 having one end attached to the base member 13 and the other end attached directly or indirectly via a hinge member 12 to the wall surface 4a of the other body 4 or the wall surface 3a of one body 3, and a connection member 15 connecting the link member 14 to the intermediate soundproof panel 7. A plurality of support means 8 are provided at predetermined intervals in the vertical direction.

[0027] In this embodiment, one end of the base member 13 is connected to the hinge member 12 that attaches one of the soundproof panels 5 to one of the frames 3, and the one end is indirectly attached to one of the frames 3 via the hinge member 12. The other end of the base member 13 protrudes into the joint portion 2, and is formed as an arm-shaped member as a whole. One end of a link member 14 is attached to this protruding end portion (other end portion). The base member 13 is long enough not to collide with the opposing frame 4 even when the joint portion 2 is at its narrowest.

[0028] The link member 14 is a pantograph-shaped member, one end of which is attached to the base member 13, and the other end of which is connected to the hinge member 12 that attaches the other soundproof panel 6 to the other body 4. That is, one end of the support means 8 is indirectly attached to one body 3 while being connected to the link member 12 that attaches one soundproof panel 5, and the other end of which is indirectly attached to the other body 4 while being connected to the link member 12 that attaches the other soundproof panel 6. By attaching them in this way, when the left and right bodies swing in different forward and backward directions, the support means 8 and the soundproof panels 5, 6, 7 rotate in the forward and backward directions in unison.

[0029] In addition, one soundproof panel 5 and the other soundproof panel 6 may be directly attached to the left and right bodies 3 and 4 via hinge members 12, and the support means 8 may also be directly attached to one body 3 and the other body 4 via hinge members 12.

[0030] The connecting member 15 is connected to a pivot part that does not displace vertically even when the link member 14 expands and contracts, and in this embodiment, one end of the connecting member 15, which is generally crank-shaped or U-shaped in plan view, is connected to the central pivot part. The other end of the connecting member 15 is connected to the intermediate soundproof panel 7, and it is preferable that the connecting portion be connected to a position that does not interfere with one of the soundproof panels 5, etc., when the joint portion 2 narrows.

[0031] In this embodiment, the abutment means 9 is a magnet 9 provided near an end of a panel body 10 constituting one of the soundproof panels 5 and the intermediate soundproof panel 7, and the magnet 9 keeps the adjacent soundproof panels 5, 6, 7 in approximate surface contact with each other at all times. In order to abut the soundproof panels 5, 6, 7 with the magnet 9, at least one of the panel body 10 or the soundproof member 11 needs to be made of a material that is attracted to the magnet 9.

[0032] As another example of the abutment means 9, an engaging portion may be formed on the panel main body 10, and a rail-shaped engaged portion with which the engaging portion slidably engages may be formed on the adjacent panel main body 10. In addition, one soundproof panel 5 and the other soundproof panel 6 may be biased so as to rotate toward the intermediate soundproof panel 7.

[0033] Incidentally, the one soundproof panel 5, the other soundproof panel 6 and the intermediate soundproof panel 7 are provided in a slightly inclined state in a plan view so that their approximate centers are located in a straight line on a perpendicular line connecting the wall surface of the one frame and the wall surface of the other frame. By providing them in this way, the ends of the soundproof panels 5, 6 can rotate smoothly in the front-rear direction without colliding with the wall surfaces of the frames 3, 4, and when used in a soundproof structure 16 for a joint portion described later, the soundproof panels can be abutted in an approximate surface contact state against the ceiling soundproofing device 17 and the floor soundproofing device 18 that abut the upper and lower ends, thereby further improving the soundproofing effect.

[0034] When soundproofing only the joints 2 between wall surfaces, it is possible to achieve this by using the wall soundproofing device 1 of the present invention. However, in order to soundproof the entire periphery of a passage-like portion protruding from the left and right structural members, for example, it is advisable to use the joint soundproofing structure 16 of the present invention which utilizes the wall soundproofing device 1 of the present invention.

[0035] As shown in Figures 5 to 7, the joint soundproofing structure 16 of the present invention is composed of a pair of wall soundproofing devices 1 installed in the joint 2 between the wall surfaces between one structure 3 and the other structure, a ceiling soundproofing device 17 installed in the joint 2 between the ceilings and installed so as to approximately abut the upper ends of the pair of wall soundproofing devices 1, and a floor soundproofing device 18 installed in the joint 2 between the floor surfaces and installed so as to approximately abut the lower ends of the pair of wall soundproofing devices 1, respectively.

[0036] In such a soundproofing structure 16 for a joint, the wall soundproofing device 1 of the present invention is provided between an interior wall joint device 19 and an exterior wall joint device 20 provided on the wall surfaces of one body 3 and the other body 4. Any type of joint device that can absorb shaking caused by an earthquake may be used for the interior wall joint device 19 and the exterior wall joint device 20. The interior wall joint device 19 constitutes a part or all of the wall surface of the connecting passage.

[0037] The ceiling soundproofing device 17 is provided in the joint portion 2 above the ceiling joint device 21 that constitutes all or part of the ceiling portion of the passageway. Any type of ceiling soundproofing device 17 may be used as long as it can absorb shaking caused by an earthquake and has a soundproofing effect, and any type of ceiling joint device 21 may be used as long as it is a joint device that can absorb shaking caused by an earthquake.

[0038] This ceiling soundproofing device 17 is arranged to protrude outward in the front-to-rear direction beyond the front-to-rear ends of the ceiling joint device 21, and the bottoms on both end sides of the ceiling soundproofing device 17 approximately abut against the upper ends of the pair of wall soundproofing devices 1, and is sized such that the approximately abutting state will not be released even if the left and right bodies 3, 4 shake due to an earthquake.

[0039] The floor soundproofing device 18 is provided in the joint portion 2 below the floor joint device 22 that constitutes all or part of the floor surface of the passageway. Any type of floor soundproofing device 18 may be used as long as it can absorb shaking caused by an earthquake and has a soundproofing effect, and any type of floor joint device 22 may be used as long as it is a joint device that can absorb shaking caused by an earthquake.

[0040] Like the ceiling soundproofing device 17, this floor soundproofing device 18 is arranged to protrude outward in the front-to-rear direction beyond the front-to-rear ends of the floor joint device 22, and the upper parts of both end sides of the floor soundproofing device 18 approximately abut against the lower ends of the pair of wall soundproofing devices 1, and are sized such that the approximately abutting state will not be released even if the left and right bodies 3, 4 shake due to an earthquake.

[0041] In this way, by providing a pair of wall soundproofing devices 1, and a ceiling soundproofing device 17 and a floor soundproofing device 18 that approximately abut the upper and lower ends of the pair of wall soundproofing devices 1, respectively, a soundproofing structure is created in which the soundproofing devices 1, 17, and 18 surround the connecting passage like a tunnel, thereby reliably blocking out noise from outside.

[0042] Incidentally, since known devices can be used for the ceiling soundproofing device 17, floor soundproofing device 18, interior wall joint device 19, exterior wall joint device 20, ceiling joint device 21, and floor joint device 22, the structures of these devices themselves have been omitted from the drawings, and the drawings mainly show the relative positions of the devices when installed.

[0043] When an earthquake causes the framework 3, 4 to shake left and right and the joint 2 to narrow, the adjacent soundproofing panels 5, 6, 7 slide left and right to increase the overlap width, absorbing the shaking caused by the earthquake, as shown in Figure 8. Also, the ceiling soundproofing device 17, floor soundproofing device 18, interior wall joint device 19, exterior wall joint device 20, ceiling joint device 21, and floor joint device 22 also follow the shaking caused by the earthquake and absorb the shaking caused by the earthquake without damaging the framework or these devices.

[0044] When an earthquake causes the framework 3, 4 to shake left and right and the joint 2 to widen, the adjacent soundproofing panels 5, 6, 7 slide left and right to reduce the overlap width, absorbing the shaking caused by the earthquake, as shown in Figure 9. Also, the ceiling soundproofing device 17, floor soundproofing device 18, interior wall joint device 19, exterior wall joint device 20, ceiling joint device 21, and floor joint device 22 also follow the shaking caused by the earthquake and absorb the shaking caused by the earthquake without damaging the framework or these devices.

[0045] When the framework 3, 4 shakes in different forward and backward directions due to an earthquake, one soundproof panel 5 and the other soundproof panel 6 rotate in the forward and backward directions around the hinge member 12 as a fulcrum, and the support means 8 of the middle soundproof panel 7 also rotates in the forward and backward directions around the hinge member 12 as a fulcrum, absorbing the shaking caused by the earthquake, as shown in Figure 10. Also, the ceiling soundproofing device 17, floor soundproofing device 18, interior wall joint device 19, exterior wall joint device 20, ceiling joint device 21, and floor joint device 22 follow the shaking caused by the earthquake and absorb the shaking caused by the earthquake without damaging the framework or these devices.

[0046] Incidentally, in the event of an earthquake, the abutment means 9 can prevent gaps from being generated between the adjacent soundproof panels 5, 6, and 7.

[0047] In the embodiment of the present invention, a form using one intermediate soundproof panel has been described, but an intermediate soundproof panel need not be used, and multiple intermediate soundproof panels may be used. When multiple intermediate soundproof panels are used, they can be supported by connecting each intermediate soundproof panel to a pivot part of the link member. When an intermediate soundproof panel is not used, it is preferable to arrange one soundproof panel attached to one body and the other end of the other soundproof panel so that they overlap the other end of one soundproof panel in the front-rear direction.

[0048] In addition, in the embodiment of the present invention, a support means using a link member or the like is used, but if there is only one intermediate soundproof panel, a support means using a rack and pinion or the like can be used.

[0049] In the first embodiment, a case where an intermediate soundproof panel is present has been described, but an intermediate soundproof panel may not be present, and one soundproof panel 5 may be combined with the other soundproof panel 6. In such an embodiment, the following configuration is adopted. "The wall soundproofing device 1 is a wall soundproofing device that is installed in the joint 2 between the wall surfaces 3a, 4a of one frame 3 and the other frame 4, and is composed of one soundproofing panel 5 having one mounting base end provided on the one frame 3, the other soundproofing panel 6 having the other mounting base end provided on the other frame 4 and the other end of the one soundproofing panel overlapping the other end of the other side of the one soundproofing panel in a facing state in the front-rear direction, and abutting means 9 that constantly abuts the other end of the other soundproofing panel and the one soundproofing panel so that no gap is generated between them. The one and other soundproofing panels (5, 6) are composed of a panel body 10 and a soundproofing member 11 that is provided so as to cover at least one side of the panel body, and are characterized in that the overlapping width of the facing wall surfaces of the one and other soundproofing panels changes during an earthquake, absorbing the shaking caused by the earthquake."
