Description
본 고안은 무대용 음향반사판에 관한 것이다. 좀더 상세하게는 가볍고 취급이 용이하며 장기간 설치해도 곡면이 펴진다거나 변형되는 일이 없어 반영구적으로 사용할 수 있는 음향반사판에 관한 것이다.The present invention relates to a stage acoustic reflector. More specifically, the present invention relates to an acoustic reflector that can be used semi-permanently because it is light, easy to handle, and does not have to be curved or deformed even after long-term installation.
음향반사판이란 성악 또는 음악을 연주하는 무대에서 연출에 따른 효과음, 관현악의 연주음 등이 스테이지 상부, 측면부, 후면부로 흩어지는 것을 막고 관객에게 음향이 충분히 전달되도록 음향을 반사시키는 시설로 무대의 상부와 측면부, 후면부에 설치했다가 사용하지 않을 때에는 상층 스테이지타워나 측면 포벳에 격납시켜 보관하는 시설이다.The sound reflection board is a facility that prevents the sound of sound produced by orchestration or orchestral music from being distributed to the upper part, the side part, and the rear part of the stage while reflecting sound so that the sound is sufficiently delivered to the audience. It is installed in the side part and the rear part, but when not in use, it is stored in the upper stage tower or side pocket.
종래 음향반사판의 패널구조를 보면 1.5m 반경의 곡면각을 갖는 여러개의 각목을 사용하여 배의 용골모양 틀을 만든 후 여기에 합판을 앞뒤로 붙여 곡면패널을 만들거나, 또는 합판이나 엠디에프(Medium Density Fiberboard)를 일정한 곡면각을 갖는 후레임에 강제로 결합시켜 곡면패널로 만든 구조로 되어 있다. 따라서, 이러한 종래의 음향반사판은 곡면패널의 복원력으로 인해 시간이 지나면 전체가 휘어지는 경우가 있으며 판과 판 사이가 떠서 무대 뒤의 빛이 들어오는 경우도 생기며 또, 중량이 너무 무거워서 이를 천장에 매다는 작업 즉, 구동시키는데 많은 에너지가 소모되는 문제점이 있다.In the panel structure of the conventional acoustic reflection board, the keel-shaped frame of the ship is made by using several pieces of wood with a curved angle of 1.5m radius, and then, the plywood is attached to the front and back to make the curved panel, or plywood or MDF Fiberboard) is a structure made of curved panels by forcibly joining a frame with a constant curved angle. Therefore, such a conventional acoustic reflector may bend over time due to the restoring force of the curved panel, and there may be a case in which light from behind the stage floats between the plate and the plate, and the weight is too heavy to suspend it on the ceiling. However, there is a problem that a lot of energy is consumed to drive.
이에, 등록실용신안공고 제20-023215호에서는, 도 1a 내지 도 1b를 참조하여, 직선형태의 알루미늄 상, 하부틀(11, 11')과 곡면각을 갖는 원호형태의 알루미늄 좌, 우측부틀(13, 13')로 이루어진 외각후레임(11',13,13'는 도시 안됨)에 우레탄 본드를 도포한 외측판(20)을 취부하고 하니콤(honey comb)(30)을 접착시킨 후, 다시 우레탄 본드를 도포한 내측판(40)을 취부하여 상기 접착제가 굳을 때까지 방치한 후에 외부 마감을 행하여 곡면패널을 제조한다. 이렇게 만들어진 곡면패널을 사용하여 음향반사판(10)을 제조하는 방법을 개시하고 있다. 그러나 상기 선고안 음향반사판 패널 또한 그 곡면을 일시적으로 강제로 구부린 것에 지나지 않아 시간이 경과되면 패널자체의 복원력에 의해 곡면이 뒤틀리거나 판과 판 사이가 어긋나는 경우가 생길 수 있다. 따라서, 이들 음향반사판의 곡면을 그대로 유지해주기 위해서는 추가로 뒷면에 받침대(패널과 동일한 곡면각을 갖는 알루미늄 바)를 대어주거나 좀더 굵고 강한 알루미늄 후레임을 사용해야한다. 이렇게 될 경우 중량이 무거워지고, 곡면형태의 유지를 위해서는 판 자체를 작게 해서 여러 개의 조각으로 설치해야하므로 연결부분이 많게되며 작업 공정이 복잡해지는 문제가 있다.Accordingly, in the Utility Model Registration No. 20-023215, with reference to Figs. 1A to 1B, aluminum-shaped left and right booths having a straight aluminum shape, lower frames 11 and 11 'and arc-shaped aluminum having curved angles ( 13, 13 ') of outer frame (11', 13, 13 'is not shown) of the outer plate 20 coated with a urethane bond, the honey comb (30) is bonded and then again After mounting the inner plate 40 coated with the urethane bond and left until the adhesive is hardened, the outer finish is performed to produce a curved panel. Disclosed is a method of manufacturing the acoustic reflector 10 using the curved panel thus made. However, the draft acoustic reflector panel is also a force of bending the curved surface temporarily, and if time passes, the curved surface may be distorted due to the restoring force of the panel itself or the plate may be displaced between the plate. Therefore, in order to maintain the curved surfaces of these acoustic reflection plates, it is necessary to additionally attach a pedestal (an aluminum bar having the same curved angle as the panel) or use a thicker and stronger aluminum frame. In this case, the weight becomes heavy, and in order to maintain the curved shape, the plate itself is made small and installed in several pieces, so that there are many connecting parts and the work process becomes complicated.
이에 본 고안자는 음향반사판의 패널 곡면이 반영구적으로 펴지지 않는 곡면패널을 제조할 수 있는 방법을 발견하게 되어 본 고안을 완성하게 되었다.Thus, the present inventors have found a method for manufacturing a curved panel in which the panel curved surface of the acoustic reflector does not spread semi-permanently, thereby completing the present invention.

본 고안 음향판사판은 그 자체가 곡면을 형성하고 있어 변형이 생기지 않으며, 가볍고 튼튼하여 설치가 간편하고 용이하도록 구성된 것임을 특징으로 한다. 본 고안 음향반사판의 곡면패널은 제조할 때에 구부린 상태에서 열로 구어 만들므로 패널 자체가 곡면을 형성하게 되고, 따라서 장기간 사용해도 변형이 되지 않는 특징을 갖는다.The present invention sound judge is characterized in that it is configured to be easy and easy to install because it forms a curved surface itself does not cause deformation, light and durable. The curved panel of the present invention acoustic reflection plate is made by bending in heat in a bent state at the time of manufacture, so that the panel itself forms a curved surface, and thus has a feature that it does not deform even after long-term use.
본 고안 음향반사판 곡면패널의 제조방법은 먼저 목재용 접착제(예; 초산비닐 에멀젼 접착제, 이소시아네이트계 우레탄수지 접착제)로 2장 내지 3장의 합판 또는 엠디에프를 접착시켜 적층판을 만든 후, 1.5m 반경 또는 3m 반경의 곡면형태로 고안된 가열 목형틀에 넣고, 열처리를 행하여 벤딩(bending)을 고정시킨다. 통상 열처리 온도는 사용하는 접착제의 종류, 경화시간에 따라 달라지는데, 본 고안의 초산비닐 에멀젼 접착제의 경우는 70℃ 내지 80℃가 적당하다. 70℃이하에서는 경화시간이 길어지고, 80℃이상에서는 접착제가 열화를 받을 우려가 있다. 상기 열처리 수단으로는 고주파 가열수단이 이용된다.The method of manufacturing the acoustic reflective plate curved panel of the present invention is first made of a laminate by bonding two or three plywood or MDF with wood adhesive (for example, vinyl acetate emulsion adhesive, isocyanate-based urethane resin adhesive), and then 1.5m radius or It is placed in a heating die frame designed to have a curved shape of 3m radius, and the bending is performed by heat treatment. In general, the heat treatment temperature varies depending on the type of adhesive used and the curing time. In the case of the vinyl acetate emulsion adhesive of the present invention, 70 ° C to 80 ° C is appropriate. At 70 degrees C or less, hardening time becomes long, and at 80 degreeC or more, there exists a possibility that adhesive may receive deterioration. As the heat treatment means, a high frequency heating means is used.
이렇게 제조한 곡면판을 상판과 하판으로 하여 상판과 하판 속 표면에 목재용 접착제를 도포하여 하니콤을 게재시키되, 상기 하니콤과 함께 벤딩 목재후레임의 곡면각과 동일한 공면각을 갖는 ㄱ자형 곡면스틸바 2개를 벤딩 목재후레임과 나란하게 설치되도록 게재시켜 곡면패널을 제조한다. 다음 상기 곡면패널의 상단과 하단에 벤딩 목재후레임을, 좌우측단에는 결합 목재후레임을 접착제로 부착하고 상, 하에서 유압프레스로 눌러 일체화시켜 음향반사판을 제조한다. 이와 같이 제조된 음향반사판들은 보강앵글을 사용하여 서로 결합한 후, 골조 스틸 각(角)파이프에 상기 ㄱ자형 스틸바를 볼트로 연결하여 조립한다.The honeycomb is placed by applying wood adhesive on the upper and lower surfaces of the curved plate thus prepared, and having the same coplanar angle as the curved angle of the bending wood frame together with the honeycomb. The two panels are placed so that they are installed side by side with the bending wood frame to produce curved panels. Next, the bending wood frame at the top and bottom of the curved panel, the left and right ends are attached to the bonding wood frame with an adhesive and press the hydraulic press up and down to manufacture a sound reflecting plate. The acoustic reflector plates manufactured as described above are coupled to each other using a reinforcing angle, and then assembled by bolting the L-shaped steel bar to a framed steel angle pipe.
본 고안에 사용하는 곡면패널의 제조에는 합판과 엠디에프를 병용할 수도 있고, 음향반사판의 미려한 외관을 위해서는 멜라민수지로 된 판지(이하 "멜라민판지"이라 함) 또는 원목무늬지를 라미네이팅 시킨 합판을 사용할 수도 있다. 또한 수요자의 요구에 따라 적당한 두께로, 적당한 크기로 다양하게 만들 수가 있다. 멜라민판지가 두꺼울 경우는 직접 접착제로 합판에 붙여서 적층판을 만들 수도 있다.In the manufacture of the curved panel used in the present invention, plywood and MDF may be used in combination, and for a beautiful appearance of the acoustic reflection board, cardboard made of melamine resin (hereinafter referred to as "melamine cardboard") or plywood laminated with wood pattern paper may be used. It may be. In addition, according to the needs of the consumer can be made in a variety of sizes and appropriate thickness. If you have a thick melamine paperboard, you can also glue the plywood directly to make a laminate.
본 고안 결합 목재후레임 단면은 종래의 직사각형 알루미늄후레임 단면(도 1a 참조) 형상과는 달리 사다리꼴 형태(도 8)를 이루고 있어 후레임 외측 결합면이 곡면각 만큼 밖으로 기울어지게 되고, 2개의 음향반사판을 결합할 때에 면과 면이 접할 수 있게(맞붙게) 되어 좀더 견고한 결합을 달성할 수가 있다. 따라서, 종래의 직사각형 알루미늄후레임(13)을 서로 결합할 때(도 1b)에 생기는 간격(δ)을 없앨 수가 있다는 특징이 있다. 이 결과 각 음향반사판 간의 결합이 튼튼할 뿐만 아니라 면과 면이 맞닿게 되어 좀더 안정된 결합형태를 이루게되는 것이다. 이하 본 고안의 바람직한 실시예를 도면에 따라 상세히 설명한다.Unlike the conventional rectangular aluminum frame cross section (see FIG. 1A), the wood frame cross section of the present invention has a trapezoidal shape (FIG. 8), so that the outside frame of the frame is inclined out by the curved angle, and the two acoustic reflection plates are combined. When you do this, the face and the face come into contact with each other to achieve a stronger bond. Therefore, there is a feature that the gap δ generated when the conventional rectangular aluminum frames 13 are joined to each other (FIG. 1B) can be eliminated. As a result, not only the coupling between the acoustic reflectors is strong but also the surfaces are in contact with each other to form a more stable coupling form. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

A 40.5 mm honeycomb 213 is disposed between the upper plate 211 and the lower plate 212 to form a curved panel 210. The panels constituting the curved surface of the curved panel 210 of the present invention are fixed to the curved surface by heating at the time of manufacture, so that the curved surface does not extend or distort even after elapse of time. Between the upper plate 211 and the lower plate 212 are two A-shaped steel bars 240 are placed side by side with the honeycomb 213, the bending wood frame 230 at the top and bottom of the curved panel, The left and right ends are coupled to the wood frame 220. The height of the various frames and the A-shaped steel bar 240 is suitable for about 40mm, which is slightly smaller than the honeycomb thickness of 40.5mm so that the honeycomb is pressed to widen the adhesive surface so that the honeycomb can maintain a more firm adhesion For sake. Both ends of the steel bar 240 are provided with two U-shaped fastening grooves 241, and the portions provided with the U-shaped fastening grooves 241 are later used by bolts 251 by picking the lower plate in a square shape. The steel bar 240 and the crosspiece steel pipe 250 is configured to facilitate coupling (FIG. 9).
도 5 내지 도 7b를 참조하여, 본 고안 목재후레임형 음향반사판(200)들은 보강앵글(231)을 사용하여 나사못으로 이웃하는 결합 목재후레임(220)끼리 결합되고, 이렇게 결합된 음향반사판(200)은 ㄱ자형 스틸바(240)의 체결홈(241)과 가로대 스틸파이프(250)를 결합하는 볼트(251)에 의해 스틸파이프(250)에 고정되고, 상기 스틸파이프(250)는 다시 세로대 스틸파이프(260)에 볼트(261) 결합되어 천장 음향반사판, 정면 음향반사판, 측면 음향반사판으로 사용된다.With reference to Figures 5 to 7b, the inventive wood frame type acoustic reflection plate 200 is coupled to each other coupled wood frame 220 with a screw using a reinforcement angle 231, the acoustic reflection plate 200 is thus combined The steel pipe 250 is fixed to the steel pipe 250 by a bolt 251 that couples the fastening groove 241 of the L-shaped steel bar 240 and the crosspiece steel pipe 250, and the steel pipe 250 is again a longitudinal steel pipe. The bolt 261 is coupled to the 260 and is used as a ceiling acoustic reflector, a front acoustic reflector, and a side acoustic reflector.
이상 상세한 설명으로 알 수 있는 바와 같이, 본 고안 결합 목재후레임(220) 단면은 종래의 직사각형 알루미늄후레임 단면 형상과는 달리 사다리꼴 형태를 이루고 있어 이웃하는 2개의 결합 목재후레임(220)이 동일한 곡면각의 평행한 면을 갖게되어 면과 면이 서로 접하게되므로 접촉 면적을 최대로 밀착결합 시킬 수가 있고, 또한 곡면패널(210) 속에 일체로 결합된 ㄱ자형 스틸바(240)는 각 음향반사판(200)을 골조 스틸파이프(250)에 연결하는 수단으로서 견고한 결합을 달성하여 안정된 결합을 확보할 수가 있다(도 7a). 이는 종래 기술에서 음향반사판(10)들을 골조인 스틸 각파이프(TE)에 결합할 때 보조 브라켓(B1)을 사용하여 결합시키는 원리(도 1b)와는 근본적으로 상이하다. 또한 본 고안 음향반사판은 곡면패널 자체의 구조가 종래의 강제 벤딩 곡면패널과는 달리 열처리로 구어서 만든 곡면을 갖는 여러 겹의 판을 결합한 적층체로 구성되어 있어 후에 다시 복원되어 펴지는 현상을 억제할 수가 있고 반영구적으로 변형 없이 사용이 가능하다.As can be seen from the above detailed description, the present invention combined wood frame 220 cross-section has a trapezoidal shape unlike the conventional rectangular aluminum frame cross-sectional shape so that the two adjacent wood frame 220 adjacent to the same curved angle Since the parallel surface is in contact with each other and the surface is in contact with each other to be able to closely contact the maximum, and also the L-shaped steel bar 240 is integrally coupled in the curved panel 210, each acoustic reflection plate 200 As a means of connecting to the framed steel pipe 250, a firm coupling can be achieved (FIG. 7A). This is fundamentally different from the principle of coupling the acoustic reflector 10 to the framed steel square pipe TE using the auxiliary bracket B1 (FIG. 1B). In addition, the acoustic reflection plate of the present invention has a structure in which the structure of the curved panel itself is composed of a laminated body in which a plurality of layers having curved surfaces formed by heat treatment, unlike the conventional forced bending curved panel, can be restrained from being restored afterwards. It can be used semi-permanently without modification.
