Description

  The present invention relates to a sound insulation panel. More specifically, the present invention relates to a sound insulation panel comprising a frame body formed by framing a frame material, a sound insulation member housed in the frame body, and a surface layer material covering the front and back surfaces of the frame body. is there.

  In recent years, in residential apartments such as condominiums, there are an increasing number of problems related to noise generated in daily life, and it is required to consider so as not to leak noise to neighboring houses across walls. In order to insulate the above noise, it is best to increase the thickness of the boundary wall, but it is necessary to make the wall of the concrete frame heavy and thick, which increases the construction cost. There's a problem.

  Therefore, in order to improve the sound insulation between adjacent rooms of an existing house, a sound insulation member such as a sound insulation sheet or a sound absorbing panel is attached to a wall surface. However, the sound insulation effect obtained by sticking only one of the above sound insulation sheets or the like is not sufficient. For this reason, it is proposed that the sound insulation member is made into a panel and attached to an existing wall.

  For example, as shown in FIG. 3 (a), the frame 9 is formed of a frame material and surface layer materials 81 and 82 that cover the front and back surfaces of the frame 9, respectively. There is known a sound insulation panel C which is reduced in weight and improved in sound insulation performance. However, although the sound insulation panel C having a hollow double wall shows improved sound insulation in the mid-high range, a drum-shaped resonance transmission phenomenon occurs in the low range, so that the sound insulation in a specific low frequency band is That's not enough.

  Therefore, for the purpose of improving the sound insulation in the specific low frequency band, as shown in FIG. 3 (b), a sound insulation material 7 made of a fibrous sound absorption material such as glass wool, a porous sound absorption material such as urethane foam, or the like is provided. There is known a sound insulation panel D in which the double wall is filled to reduce transmission in the low sound range and improve sound insulation in the middle and high sound ranges.

  In order to manufacture the sound insulation panel D, it is necessary to join the surface layer material 81, the surface layer material 82, and the frame body 9 shown in FIG. At this time, for example, when the frame 9 and the surface layer materials 81 and 82 are bonded to each other by filling a fibrous sound insulating material 7 such as glass wool into the bonding surface, glass wool is mixed into the bonding surface to inhibit adhesion. Problems arise.

  Therefore, a technique using a punching board as a sound absorbing material instead of the above-described sound insulating material 7 is disclosed. Japanese Patent Publication No. 63-62614 discloses a first punching board in which first holes are formed in the vertical and horizontal directions, and a vertical and horizontal direction so as to be superimposed on the first punching board and shifted in position with respect to the first holes. A second punching board having a second hole formed therein and a long hole that is interposed between the first punching board and the second punching board and communicates with the first hole and the second hole. There is disclosed a sound insulation building material comprising a third punching board formed on the outside, and the outsides of the first punching board and the second punching board being covered with a non-porous surface layer material, respectively.

  According to the above technique, a series of holes forms a kind of duct and prevents the traveling plane wave from advancing, so that it has a sound attenuation effect and constitutes a single expansion cavity type silencer. There is also a description of its effect when it exhibits sound insulation.

  However, in the technique described in the above publication, since the first punching board, the second punching board, and the third punching board are in contact with each other, the traveling plane wave is generated by a duct formed by a series of holes. Even if the forward movement is hindered, since the three boards are in physical contact with each other, it is difficult to cut off the vibration of the sound wave due to conduction, and the sound insulation is not necessarily excellent.

  On the other hand, the well-known sound insulation panel configured as described above often uses a board material such as a wood board, a gypsum board, and a calc board as a surface layer material. Used in combination by the method. However, plate materials such as the above-mentioned wood board, gypsum board, and calc board vibrate due to the incidence of sound waves, and there is also a problem that the sound insulation performance is lowered because the vibration is transmitted between the sound insulation panels to form a complicated vibration mode.

Japanese Examined Patent Publication No. 63-62614

  The invention of the present application was made to solve such a problem, and the purpose of the present invention is to be used by sticking to a wall surface so as not to leak noise to a neighbor across the wall in an apartment etc. The object is to provide a sound insulation panel with excellent sound insulation properties that can block outdoor noise even when enjoying a full home theater in the home or playing a piano or other musical instruments.

  In order to solve the above-mentioned problems, a sound insulation panel according to the first aspect of the present invention comprises a plate member fixed to a front surface and a rear surface of a frame body formed by framing a frame material to form a hollow panel. In addition, a plurality of perforated plates provided with a large number of through holes are placed in the hollow panel, and the plurality of perforated plates and the plate material fixed to the front and back surfaces and the perforated plates are spaced apart from each other. It is provided and arranged in parallel, and the edge portions of the plurality of perforated plates are held by the frame body.

  According to a second aspect of the present invention, there is provided a sound insulation panel according to the first aspect of the present invention, wherein the side frame of the frame body is formed of a vibration damping material, and the outer panel of the vibration damping material is connected to an adjacent panel. It is characterized in that an engaging concavo-convex portion is formed.

  In the sound insulation panel according to the first aspect of the present invention, a hollow panel is formed by fixing plate members on the front and back surfaces of the frame body, and a plurality of cables having a plurality of through holes provided in the hollow panel. Since the perforated plate and the perforated plate fixed on the front and back surfaces are arranged in parallel with a space between them, that is, they are not contact-polymerized with each other. The vibration of the transmitted sound wave can be prevented and the sound can be effectively insulated.

  In addition, for example, when a perforated plate is manufactured by cutting a predetermined size from a long or large size woody punching board or the like, the perforations drilled in each perforated plate due to a cutting dimension error or the like The holes are not completely in the same position, and when a plurality of perforated plates are mounted in parallel to each other, the through holes may be opposed to each other accurately in the vertical direction due to construction installation error. Therefore, sound transmission due to air vibration in the hollow panel is effectively suppressed, and the sound insulation effect can be enhanced.

  In addition, since there are multiple perforated plates, the shape, hole diameter, pitch, etc. of the through holes can be selected and adopted as necessary, and it is the most suitable for blocking the sound generated at the installation location of the sound insulation panel. A suitable sound insulation panel can be prepared simply by adjusting the combination of perforated plates.

  In the sound insulation panel according to the second aspect of the present invention, since the side frame of the frame body is formed of a vibration damping material such as rubber or soft plastic, for example, the surface side plate material by noise from the outdoor side Even if the vibration occurs, the vibration damping material absorbs the vibration like a cushion to prevent the vibration from propagating through the hollow panel, and the sound insulation performance can be improved without causing the back side plate material to resonate.

  In addition, when the edge of the perforated plate is held by a slit or the like provided on the inner surface of the side frame of the frame body made of rubber or soft plastic, the shape of the holding means such as the slit is set in advance when the side frame is formed. By providing the mold, it is possible to mass-produce accurately and easily.

  Further, since the engaging concavo-convex portion for connecting the adjacent panel is formed on the outer side surface of the side frame made of the vibration damping material, the engaging concavo-convex portion and the engaging ridge portion have rubber elasticity and are actually connected. By doing so, it is possible to provide a plurality of sound insulation panels that are closely connected with each other without causing a gap, and sound can be effectively insulated while preventing sound leakage.

  In this way, even if you enjoy a full-fledged home theater at home, or play piano or other musical instruments as a hobby or practice, you can prevent indoor sound from leaking outside and effectively make noise from the outside A sound insulation panel for blocking can be provided.

It is a section explanatory view showing typically the composition of the sound insulation panel concerning a 2nd embodiment of the invention in this application. (A) is sectional explanatory drawing which shows a well-known sound insulation panel typically, (b) is sectional explanatory drawing which shows another known sound insulation panel typically.

  Hereinafter, embodiments of a sound insulation panel according to the present invention will be described in detail with reference to the drawings. Fig.1 (a) is sectional explanatory drawing which shows typically the structure of the sound insulation panel A concerning 1st Embodiment of the said invention.

  As shown in FIG. 1A, the sound insulation panel A has a plate material 21 made of a wooden material on the front side of a frame 1 formed by framing a frame material, and a plate material 22 made of a wooden material on the back side. A hollow panel 3 is formed by being fixed, and a perforated plate 41 made of the same wood material is housed on the front side and a perforated plate 42 is placed on the back side in the hollow panel 3.

  The two perforated plates 41 and the perforated plate 42 are provided parallel to each other with the front surface side plate material 21 and the back surface side plate material 22 being spaced apart from each other, and spaced apart from each other by a distance d. The edge portions of 41 and 42 are held by the frame 1. In this way, the front side plate member 21 and the one perforated plate 41 are provided apart from each other, and similarly, the rear side plate member 22 and the other perforated plate 42 are provided separately from each other. The back side plate member 22 and the two perforated plates 41 and 42 are not in contact with each other.

  FIG. 1B is a plan view schematically showing the perforated plate 41 (42). In FIG. 1B, the perforated plate 41 (42) has a thickness of 3 mm to 12 mm, and the perforated plate 41 (42) is provided with a through hole 411 (421) having a diameter of about 4 mm to 15 mm. Yes.

  Here, the perforated plate 41 on the front surface side and the perforated plate 42 on the back surface side are manufactured by cutting out a predetermined dimension from a long or large punching board or the like. Due to errors, the through positions of the through holes 411 and 421 of the perforated plates 41 and 42 are slightly different from each other and are not exactly the same through position. Therefore, when the two perforated plates 41 and 42 are mounted in parallel with the front surface side plate material 21 and the back surface side plate material 22, the through hole 411 and the through hole 421 do not accurately face each other in the vertical direction. In addition, it is impossible that the through hole 411 and the through hole 421 are accurately opposed to each other in the vertical direction due to a mounting dimension error during construction.

  Therefore, in the hollow panel 3, transmission of sound waves due to air vibration is suppressed, and the front side plate member 21 and the rear side plate member 22 are not in contact with each other via the two perforated plates 41 and 42. Therefore, the sound insulation panel has a large sound insulation effect.

  Here, for example, when the front side plate material 21 is arranged outdoors and the back side plate material 22 is arranged indoors, when noise from the outside of the room, for example, exhaust gas noise of a car, etc. By selecting the plate thickness of the perforated plate 41, the hole diameter of the through holes 411, the formation pitch of the through holes 411, and the like, it is possible to effectively block the middle and low-frequency noise from the outdoor side.

  On the other hand, in order to prevent indoor noise such as piano sound, etc., from leaking outside, the thickness of the perforated plate 42, the hole diameter of the through holes 421, the formation pitch of the through holes 421, etc. By selecting, the noise leaking from the indoor side to the surroundings can be effectively insulated. In this way, by adjusting the characteristics of the two perforated plates 41 and 42, it is possible to effectively and efficiently take measures against sound insulation such as sound insulation from outside and sound leakage from the room at the installation location of the sound insulation panel A. Can be done automatically.

  FIG. 2 is a cross-sectional explanatory view schematically showing the configuration of the sound insulation panel B according to the second embodiment of the present invention. In the sound insulation panel B, the left and right side frames 11 of the frame 1 are formed of a vibration damping material such as a rubber member. Since the left and right side frames 11 are formed of a damping material in this way, even if noise (sound pressure) from the outside vibrates the front side plate material 21, the rubber member absorbs the vibration like a cushion. The vibration is prevented from propagating through the hollow panel 3 to resonate the back side plate 22.

  In addition, a slit 111 is provided on the inner side surface of the left and right side frames 11, and the edge portions of the perforated plates 41 and 42 are fitted into the slit 111 so that the two perforated plates 41 and 42 are formed in the hollow panel 3. Holds firmly. At this time, even if the sound waves from the outdoor side or the indoor side vibrate the front-side plate material 21 and the back-side plate material 22, and the vibration propagates to the perforated plates 41, 42, the edge portions of the perforated plates 41, 42 Is elastically held by the slit 111, so that a sound insulation effect can be effectively exhibited without resonance or resonance.

  Furthermore, an engagement concave portion 5 and an engagement convex portion 6 for connecting adjacent panels are formed on the outer surfaces of the left and right side frames 11. Since the engaging concave portion 5 and the engaging convex portion 6 have rubber elasticity, they can be compressed and actually connected, and a plurality of sound insulation panels B can be connected closely without causing a gap. Yes, sound can be effectively insulated.

  Furthermore, even if vibration occurs in some of the sound insulation panels B, the left and right side frames 11 absorb the vibration and are not easily transmitted to the adjacent sound insulation panels B, so that noise expansion can be effectively insulated. In addition, the left and right side frames 11 have rubber elasticity, so they are compressible, and when the sound insulation panel is installed, it absorbs dimensional errors of the panel itself and errors due to deformation of buildings and housings, resulting in a beautiful finish with no gaps. be able to.

  In addition, although the above-mentioned embodiment demonstrated the case where there were two perforated plates, you may install three or more sheets in a hollow panel. Further, a sound absorbing material such as felt may be filled in the hollow portion of the hollow panel.

  Furthermore, not only the sound insulation panel of the present invention is used for sound insulation purposes, but the sound insulation panel itself may be used as a partition panel that also serves as a sound insulation panel for an office or a general house. As described above, the present invention can be modified in design and is included in the technical scope of the present invention without departing from the scope of the claims.
