Abstract
Description
[Technical field]
[0001] The present invention relates to a soundproof partition wall provided between left and right building frames. [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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] 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.
[0015] 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.
[0016] In a first embodiment for carrying out the present invention shown in Figures 1 to 6, reference numeral 1 denotes a soundproof partition wall installed in a joint 2 between one body 3 and another body 4. In this embodiment, the soundproof partition wall is provided in the joint 2 between wall surfaces, and is disposed between an outer wall and an inner wall.
[0017] As shown in Figures 1 and 2, for example, this soundproof partition wall 1 is composed of a support mechanism 5 having one end attached to one of the structures 3 and the other end attached to the other structure 4, a pair of plate-shaped end soundproof panels 6 having one end attached near both ends of the support mechanism 5 or to the one structure 3 and the other structure 4, and at least one plate-shaped intermediate soundproof panel 7, one in this embodiment, which is attached to the support mechanism 5 so as to be movable in the front-to-rear direction, is provided between the pair of end soundproof panels 6, and covers the joint portion.
[0018] In this embodiment, a pantograph-type link mechanism is used as the support mechanism 5, and both ends of this support mechanism 5 are attached to the left and right bodies 3, 4 by hinge members 8 so that they can move in the front-rear direction.
[0019] In this embodiment, one end of each of the pair of end soundproofing panels 6 is attached to both ends of the support mechanism 5, and the other end (protruding end) is provided with an extrusion inclined surface 9 that can push the intermediate soundproofing panel forward. A flexible sealant 19 or the like is filled between one end of each of the end soundproofing panels 6 and the left and right bodies 3, 4.
[0020] This end soundproofing panel 6 is composed of a plate-shaped end panel body 10 and an end panel soundproofing material 11 provided on the surface of the end panel body 10, and the protruding end side of the end panel body 10 is formed into an inclined surface.
[0021] The end panel body 10 is a plate-like member, and is preferably formed from a plate material capable of absorbing sound, such as a sound-absorbing material.
[0022] In this embodiment, a sheet-like member having soundproofing properties, preferably lead, is used as the end panel soundproofing material 11. It is preferable that the end panel soundproofing material 11 is provided so as to cover the inclined surface formed on the protruding end side of the end panel main body 10.
[0023] In this embodiment, the end soundproofing panel 6 is attached near the end of the support mechanism 5, but it may be attached to the left and right frameworks via hinge members or the like.
[0024] The intermediate soundproof panel 7 is disposed so that both ends thereof are substantially in contact with the protruding ends of the end soundproof panels 6, and is attached to the support mechanism 5 via attachment means 12 so as to be movable in the front-rear direction.
[0025] It is desirable that both ends of the intermediate soundproof panel 7 are formed with inclined surfaces 13 that substantially abut against the extruded inclined surfaces 9. By forming such inclined surfaces 13, the intermediate soundproof panel 7 can move forward smoothly during an earthquake. Here, "substantially abut" includes not only a state of contact, but also a state of being close to each other with a small gap.
[0026] The mounting means 12 of the intermediate soundproof panel 7 is connected to the vicinity of the approximate center of the intermediate soundproof panel 7 and is composed of a mounting member 15 which penetrates the central pivot part 14 of the support mechanism 5, and a biasing device 16 such as a spring which constantly biases the mounting member 15 backward (toward the back surface of the intermediate soundproof panel 7). The central pivot part 14 refers to a pivot part located approximately in the center of the support mechanism 5 in the up-down direction.
[0027] This intermediate soundproof panel 7 is composed of a plate-shaped intermediate panel body 17, and an intermediate panel soundproofing material 18 provided on the surface of the intermediate panel body 17 and provided so as to protrude in the left-right direction beyond both ends of the intermediate panel body 17. By providing the intermediate panel soundproofing material 18 so as to protrude in the left-right direction beyond both ends of the intermediate panel body 17, the intermediate panel soundproofing material 18 comes into substantial contact with the surface of the end panel soundproofing material 11 in a substantial surface contact state, and the entire joint portion 2 can be covered with the soundproofing materials 11, 18 without any gaps.
[0028] Incidentally, like the end panel body 10, the intermediate panel body 17 is desirably formed of a plate material capable of absorbing sound, such as a sound-absorbing material, and like the end panel soundproofing material 11, the intermediate panel soundproofing material 18 is made of a sheet-like material having soundproofing properties, preferably lead. In this embodiment, the intermediate panel body 17 is formed with the inclined surface 13, but the intermediate panel body 17 may be formed in a thin plate shape, and the intermediate panel soundproofing material 18 may be used to form the inclined surface 13, to form an intermediate soundproofing panel 7.
[0029] The end panel body 10 and the intermediate panel body 17 may be composed of only the soundproofing materials 11, 18, or the end soundproofing panel 6 and the intermediate soundproofing panel 7 may be formed by fitting the end panel body 10 and the intermediate panel body 17 into a frame-shaped frame member. By fitting the end panel body 10 and the intermediate panel body 17 into a frame-shaped frame member, the strength can be further improved.
[0030] When an earthquake causes the left and right frames 3, 4 to shake so that the joint 2 narrows, as shown in Figure 5, the middle soundproofing panel 7 is pushed out by the extrusion inclined surfaces 9 of the left and right end soundproofing panels 6, and moves approximately parallel to the front side to absorb the shaking.
[0031] When the shaking caused by the earthquake ends, the intermediate soundproof panel 7 is displaced in parallel backward by the force of the biasing device 16 and returns to its normal state.
[0032] When an earthquake causes the left and right frames 3, 4 to shake so that the joint 2 widens, the middle soundproofing panel 7 and the end soundproofing panel 6 move apart, absorbing the shaking caused by the earthquake, as shown in Figure 6. At this time, the soundproofing function is temporarily lost, but this is only for a short time while the earthquake is occurring, and once the shaking caused by the earthquake ends, the normal state is restored and the soundproofing function is restored as well.
[0033] [Different modes for carrying out the invention] Next, a description will be given of different embodiments for carrying out the present invention shown in Figures 7 and 8. In describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are designated by the same reference numerals, and duplicated descriptions will be omitted.
[0034] The second form for implementing the present invention shown in Figures 7 and 8 mainly differs from the first form for implementing the present invention in that a plurality of intermediate soundproofing panels 7, 7A, specifically three intermediate soundproofing panels 7, 7A, are used and the intermediate soundproofing panel 7 adjacent to the end soundproofing panel 6 is configured to move forward during an earthquake; with such a soundproof partition wall 1A, the same effect as in the first form for implementing the present invention can be obtained.
[0035] In this embodiment, extrusion inclined surfaces 9 are provided on the end soundproofing panels 6 and the intermediate soundproofing panel 7A in the center of the joint, and when the left and right bodies 3, 4 shake due to an earthquake so that the joint 2 narrows, the intermediate soundproofing panel 7 located between the end soundproofing panels 6 and the central intermediate soundproofing panel 7A is pushed out by the extrusion inclined surfaces 9 of the left and right end soundproofing panels 6 and the central intermediate soundproofing panel 7A, and moves approximately parallel to the forward side to absorb the shaking.
[0036] In this embodiment, during an earthquake, the intermediate soundproofing panel 7 located between the end soundproofing panel 6 and the central intermediate soundproofing panel 7A moves approximately parallel to the forward side, so this intermediate soundproofing panel 7 is attached to the support mechanism 5 by mounting means 12, and the central intermediate soundproofing panel 7A is fixedly attached to the support mechanism 5 to prevent it from moving forward.
[0037] In the present embodiment, the end soundproofing panel 6 and the central intermediate soundproofing panel 7A are provided with the extruded inclined surface 9, but the end soundproofing panel 6 and the central intermediate soundproofing panel 7 may be configured to move when pressed. In such a case, the extruded inclined surface 9 is formed on the intermediate soundproofing panel 7A adjacent to the end soundproofing panel 6. The end soundproofing panel 6 or the intermediate soundproofing panel 7 that is extruded and moves approximately parallel during an earthquake may be provided with an end panel soundproofing material 11 or an intermediate panel soundproofing material 18 so as to protrude in the left-right direction beyond both ends of the end panel main body 10 or the intermediate panel main body 17, respectively, so as to overlap with the surface of the adjacent end soundproofing panel 6 or intermediate soundproofing panel 7.
[0038] In this embodiment, three intermediate soundproofing panels 7 are provided, but two intermediate soundproofing panels 7 may be provided, or four or more intermediate soundproofing panels 7 may be provided.
[0039] In the embodiment of the present invention, the soundproof partition wall of the present invention is disposed in the joint between the wall surfaces, but the soundproof partition wall of the present invention may be disposed in the joint of the ceiling. When used in the ceiling, it is preferable to dispose it between the ceiling joint device and the ceiling space. In such a case, a weight may be used as the biasing device.
[0040] In addition, in the embodiment of the present invention, a support mechanism using a link member or the like is used, but if there is only one intermediate soundproof panel, a support mechanism using a rack and pinion or the like can be used. [Industrial Applicability]
[0041] The present invention finds application in the industry of manufacturing soundproof partition walls. [Explanation of symbols]
