하니콤 구조의 흡음, 단열 보강패널{Reinforced panel for sound absorption and heat insulation with honeycomb structure and piercing panel}Reinforced panel for sound absorption and heat insulation with honeycomb structure and piercing panel}

본 발명은 건축용 내외장재로 사용되는 하니콤 구조의 흡음, 단열 보강패널에 관한 것으로서, 보다 구체적으로는 상호 이격 거리를 두고 판면이 서로 마주보도록 구비되는 베이스패널과 타공판 사이에 다수의 중공부가 형성될 수 있도록 일정 높이의 보강재를 구비하고, 상기 타공판에는 상기 중공부에 각각 대응되게 흡음공을 관통 형성하여 외부의 소음이 상기 흡음공을 통해 중공부로 유입되어 소멸되게 함으로써, 흡음 및 방음효과는 물론 단열효과가 우수하고, 구조가 간단할 뿐 아니라, 충격이나 변형 등에 대한 물리적 특성이 우수한 하니콤 구조의 흡음, 단열 보강패널에 관한 것이다.The present invention relates to a sound-absorbing, heat-insulating reinforcing panel of the honeycomb structure used as building interior and exterior materials, and more specifically, a plurality of hollow parts may be formed between the base panel and the perforated plate provided to face each other at a distance apart from each other. It is provided with a reinforcement of a certain height so that the perforated plate through the sound absorbing hole corresponding to each of the hollow portion so that the outside noise is introduced into the hollow portion through the sound absorbing hole to be extinguished, sound absorption and sound insulation effect as well as thermal insulation effect The invention relates to a sound absorbing and heat insulating reinforcing panel of a honeycomb structure which is excellent in structure and is simple in structure and excellent in physical properties against impact and deformation.

일반적으로 하니콤 구조의 보강패널은 건축용 내외장재로 주로 사용되는 것으로서, 철도, 차량 등의 제작시에도 냉,난방재 또는 보강재로 많이 사용되고 있는 복합패널이다.In general, the reinforcement panel of the honeycomb structure is mainly used as interior and exterior materials for building, and is a composite panel that is frequently used as a cooling, heating, or reinforcing material even when manufacturing railroads and vehicles.

이러한 하니콤 구조의 보강패널은 알루미늄이나 도금강판 등의 금속재나 수지 또는 석고보드 등의 비금속재로 형성된 한쌍의 박판 사이에 벌집 모양 또는 파 형의 하니콤 코어가 설치된다.The honeycomb reinforcement panel is provided with a honeycomb-shaped or honeycomb-shaped honeycomb core between a pair of thin plates formed of a metal material such as aluminum or a plated steel sheet or a non-metal material such as resin or gypsum board.

상기와 같이 한 쌍의 박판 사이에 하니콤 코어가 설치됨으로써 하니콤 구조의 보강패널은 내부에 일정크기의 다수의 중공부(셀)가 형성된 복합패널을 형성하게 되는 것이다.As the honeycomb core is installed between the pair of thin plates as described above, the reinforcement panel of the honeycomb structure forms a composite panel in which a plurality of hollow portions (cells) of a predetermined size are formed.

따라서 하니콤 구조의 보강패널은 하니콤 코어에 의해 내부에 다수의 중공부가 형성됨으로써, 경량일 뿐 아니라, 단열효과가 우수하여 건축물의 벽면 또는 천정이나, 철도, 차량 등의 냉,난방 단열재로 사용되고 있다.Therefore, the honeycomb reinforcement panel is formed of honeycomb cores with a large number of hollows, and is not only lightweight but also excellent in heat insulating effect. have.

한편, 상기와 같은 종래의 하니콤 구조의 보강패널은 외부 소음을 흡수할 수 없기 때문에 종래에는 주로 별도의 방음패널을 설치하여 외부 소음을 차단시키거나, 또는 종래의 하니콤 구조의 보강패널이 외부 소음을 차단할 수 있도록 차음재나 흡음재 등을 내부에 형성된 중공부에 충진시키거나 또는 박판 외측면에 차음재나 흡음재 등을 코팅하여 사용하였다.Meanwhile, since the conventional honeycomb reinforcement panel cannot absorb external noise, conventionally, a separate soundproofing panel is mainly installed to block external noise, or the conventional honeycomb reinforcement panel is external. In order to block noise, a sound insulating material or a sound absorbing material was filled in the hollow formed inside, or a sound insulating material or sound absorbing material was coated on the outer surface of the thin plate.

그러나 상기와 같은 종래의 하니콤 구조의 보강패널은 다음과 같은 문제점들이 있었다.However, the conventional honeycomb reinforcement panel has the following problems.

첫째, 외부의 소음을 흡수하여 완화시키거나 소멸시킬 수 있는 구조가 없기 때문에 외부의 소음이 금속재 또는 비금속재로 형성된 박판의 전면에 반사되게 됨으로써, 소음을 흡수 또는 차단시킬 수 없어 방음패널이나 흡음패널로 사용할 수가 없었고, 둘째, 소음을 차단하기 위하여 별도의 방음패널을 사용하거나 또는 종래의 하니콤 구조의 보강패널에 차음재나 흡음재를 충진 또는 코팅하여 사용하는 경우에는 방음패널이 고가일 뿐 아니라 구조가 복잡하고, 차음재나 흡음재의 충진 또는 코팅으로 인해 중량이 증대되는 문제점이 있었으며, 셋째, 단열효과를 위하여 판재의 두께를 두껍게 하거나 하니콤 코어의 두께를 두껍게 해야 하므로 비경제적인 요인이 되어 왔다.First, since there is no structure that can absorb or mitigate external noise, the external noise is reflected on the front surface of the thin plate formed of metal or non-metallic material, so the sound absorbing panel or sound absorbing panel cannot be absorbed or blocked. Second, in case of using a separate soundproof panel to block noise or filling or coating a soundproof material or sound absorbing material in a reinforcement panel of a conventional honeycomb structure, the soundproof panel is not only expensive but also has a structure. Complex, there was a problem that the weight is increased due to the filling or coating of the sound insulating material or sound absorbing material, and third, it has been an uneconomical factor to thicken the thickness of the plate or the thickness of the honeycomb core for the insulation effect.

베이스패널(20)과 타공판(1)은 사각형상의 일정 두께를 가진 박판으로 형성되는 것으로서, 철재, 알루미늄 또는 도금강판 등의 금속재로 형성되거나, 수지판, 합판, 석고보드 등의 비금속재로 형성될 수 있다.The base panel 20 and the perforated plate 1 are formed of a thin plate having a predetermined thickness in a rectangular shape, and may be formed of a metal material such as iron, aluminum, or plated steel sheet, or may be formed of a nonmetal material such as a resin plate, plywood, or gypsum board. Can be.

한편, 베이스패널(20)과 타공판(1) 사이에는 보강재(10)가 배치된다.Meanwhile, the reinforcing material 10 is disposed between the base panel 20 and the perforated plate 1.

보강재(10)는 도 1에 도시된 바와 같이, 육각기둥 형태의 공간부로 형성된 다수의 셀(15)이 배열 설치되는 하니콤 코어로 형성될 수 있다.As shown in FIG. 1, the reinforcement 10 may be formed of a honeycomb core in which a plurality of cells 15 formed as a hexagonal pillar-shaped space part are arranged.

보강재(10)는 정육각형의 일측 세변에 해당되는 절곡편(12)과 이 정육각형의 한 변의 길이에 해당되는 직선편(13)이 길이 방향을 따라 교대로 반복해서 길게 연결되는 복수의 띠 형태의 부재를 서로 마주보는 상태로 직선편(13)이 밀착되게 하여 동일 평면상에서 순차적으로 결합시켜 형성된다.The reinforcement 10 has a plurality of strip-shaped members in which a bending piece 12 corresponding to one side of a regular hexagon and a straight piece 13 corresponding to the length of one side of the regular hexagon are alternately and repeatedly connected along the length direction. The straight pieces 13 are brought into close contact with each other in a state where they face each other and are sequentially formed on the same plane.

이때 띠 형태의 부재는 용접 또는 접착제 등을 이용하여 서로 결합시킬 수 있다.In this case, the strip-shaped members may be bonded to each other by using welding or an adhesive.

보강재(10)에 형성되는 셀(15)은 하니콤 코어의 정육각형으로 한정되는 것은 아니며, 정육각형 외에 사각형이나 오각형 등 다양한 형태로 형성될 수 있다.The cell 15 formed in the reinforcement 10 is not limited to the regular hexagon of the honeycomb core, but may be formed in various shapes such as a square or a pentagon in addition to the regular hexagon.

또한 보강재(10)는 철재, 알루미늄, 수지 또는 종이로도 형성될 수 있다.In addition, the reinforcing material 10 may be formed of iron, aluminum, resin or paper.

한편 타공판(1)에는 보강재(10)에 형성되는 다수의 셀(15)에 대응되는 위치에 흡음공(5)이 각각 관통 형성된다.In the perforated plate 1, sound absorbing holes 5 are respectively formed at positions corresponding to the plurality of cells 15 formed in the reinforcing material 10.

흡음공(5)의 직경은 0.5 - 1.0 mm로 형성되는 것이 바람직하다.It is preferable that the diameter of the sound absorption hole 5 is 0.5-1.0 mm.

이때 흡음공(5)은 원형으로 한정되는 것은 아니며, 원형 외에 사각형, 오각형, 육각형 등 다각형으로 형성될 수도 있고, 또는 슬릿(SLIT) 형태로 형성될 수도 있다.In this case, the sound absorbing hole 5 is not limited to a circle, and may be formed in a polygon, such as a rectangle, a pentagon, a hexagon, or a slit (SLIT) in addition to a circle.

본 발명은 도 2에 도시된 바와 같이, 베이스패널(20) 위에 보강재(10)와 타공판(1)이 순차적으로 배치되어 결합되며, 이때 베이스패널(20)과 타공판(1) 및 보강재(10)는 용접이나 접착제 등을 이용하여 결합시킨다. As shown in FIG. 2, the reinforcement 10 and the perforated plate 1 are sequentially disposed and coupled to the base panel 20, and the base panel 20, the perforated plate 1, and the reinforcement 10 are sequentially arranged. Join using welding or adhesives.

또한 베이스패널(20)이나 타공판(1)의 외측면에는 불연성 세라믹을 코팅하여 내열성, 내오염성, 내변색성 등을 가질 수 있게 할 수 있다.In addition, the outer surface of the base panel 20 or the perforated plate 1 may be coated with a non-flammable ceramic to have heat resistance, stain resistance, discoloration resistance, and the like.

한편 본 발명의 내부에는 베이스패널(20)과 타공판(1) 및 보강재(10)가 결합된 상태에서 보강재(10)에 형성된 셀(15)에 의해 밀폐된 다수의 중공부가 형성되게 되며, 타공판(1)에 형성된 흡음공(5)은 다수의 중공부의 중앙부에 각각 위치하게 된다.On the other hand, the interior of the present invention is to form a plurality of hollow parts sealed by the cell 15 formed in the reinforcing material 10 in the state in which the base panel 20, the perforated plate 1 and the reinforcing material 10 is combined, the perforated plate ( Sound absorbing holes (5) formed in 1) are respectively positioned in the central portion of the plurality of hollow portions.

따라서 보강재(10)의 셀(15)에 의해 형성된 중공부는 타공판(1)의 흡음공(5)에 의해 외부와 연통되게 된다.Therefore, the hollow portion formed by the cell 15 of the reinforcing material 10 is in communication with the outside by the sound absorbing hole 5 of the perforated plate 1.

한편, 도 3은 본 발명의 하니콤 구조의 흡음 보강패널의 부분 단면도를 나타낸 것이고, 도 4는 본 발명의 타공판(1)에 형성된 흡음공(5)이 보강재(10)의 셀(15)에 복수로 대응되게 형성된 상태의 부분 단면도를 나타낸 것이다.On the other hand, Figure 3 shows a partial cross-sectional view of the sound absorbing reinforcement panel of the honeycomb structure of the present invention, Figure 4 is a sound absorbing hole 5 formed in the perforated plate 1 of the present invention to the cell 15 of the reinforcing material 10 It shows a partial cross-sectional view of a state formed corresponding to a plurality.

도시된 바와 같이, 흡음공(5)은 보강재(10)에 연속하여 형성되는 셀(15)의 중앙부에 위치하게 된다.As shown, the sound absorbing hole 5 is located in the center portion of the cell 15 formed continuously to the reinforcing material (10).

이하 외부 소음의 유입과 소멸과정을 도면을 참조하여 상세히 설명한다.Hereinafter, the inflow and extinction process of external noise will be described in detail with reference to the accompanying drawings.

도 3에 도시된 바와 같이, 외부 소음의 음파는 화살표와 같이 흡음공(5)을 통해 셀(15) 내부로 진입하게 된다.As shown in FIG. 3, sound waves of external noise enter the cell 15 through the sound absorbing holes 5 as shown by arrows.

한편 음파는 일정한 주기로 진동하는 파동으로서, 소음의 경우 서로 다른 파동을 가지는 다수의 음파가 혼합된 상태로 매질(媒質)(공기)을 진행하게 된다.On the other hand, the sound wave is a wave oscillating at a constant cycle, and in the case of noise, the medium (air) proceeds in a state in which a plurality of sound waves having different waves are mixed.

이와 같이 음파는 매질(媒質) 속을 전파하는 탄성파(彈性波)로서 보통 가청주파수(可聽周波數:수십∼2만 Hz)의 것을 가리키며, 각각의 매질에 특유한 전파속도가 있으며, 반사·간섭·회절 등 파동으로서의 모든 성질을 지니고 있다As such, sound waves are elastic waves propagating in a medium, and usually refer to those having an audible frequency (several frequencies of several hundred to 20,000 Hz), and have a propagation speed specific to each medium.・ It has all the properties as a wave, such as a diffraction

파동은 진행도중 장애물을 만나면 그 주위를 돌아서 전달되고, 좁은 틈을 통 과하는 경우에는 원래의 진행 방향과는 다른 방향으로 넓게 퍼져 구면파로 전달되는 회절현상을 나타내게 된다.When a wave encounters an obstacle in progress, the wave is transmitted around it, and when passing through a narrow gap, the wave spreads widely in a direction different from the original direction of propagation, indicating a diffraction phenomenon.

또한 파동은 서로 다른 경로를 통해 진행하는 도중에 서로 만나게 되면 진폭이 커지거나 작아지게 되어 서로 상쇄되는 간섭 현상이 나타나게 되며, 진동수가 약간 다른 두 음파가 서로 간섭을 일으키게 되면 소리의 세기가 주기적으로 변화되면서 소멸되는 맥놀이 현상도 발생하게 된다.In addition, if the waves meet each other while traveling through different paths, the amplitude increases or decreases, causing interference to cancel each other, and when two sound waves with slightly different frequencies interfere with each other, the intensity of the sound changes periodically. The disappearing beat phenomenon will also occur.

따라서, 도 3에 도시된 바와 같이, 외부 여러 소음이 혼합된 음파가 화살표와 같이 타공판(1)의 흡음공(5)으로 진입하게 되면 음파는 흡음공(5)을 통과하면서 회절현상이 발생되어 구면파로 전환되게 되고, 이 구면파는 보강재(10)의 셀(15)의 내부로 퍼져나가게 된다.Therefore, as shown in FIG. 3, when sound waves mixed with various external noises enter the sound absorbing hole 5 of the perforated plate 1 as shown by the arrow, the sound wave passes through the sound absorbing hole 5 and diffraction occurs. The spherical wave is converted into a spherical wave, and the spherical wave spreads into the cell 15 of the stiffener 10.

이때 음파는 화살표와 같이 여러 경로를 따라서 셀(15) 내부의 벽면에 반사되어 진행하게 되고, 이 음파들이 서로 간섭되게 되어 소리의 크기가 감소되거나 또는 서로 상쇄되어 소멸되게 되는 것이다.At this time, the sound waves are reflected on the wall surface inside the cell 15 along the various paths as shown by the arrow, and these sound waves are interfered with each other so that the volume of sound is reduced or canceled out.

한편 도 4는 하나의 셀(15)에 흡음공(5)이 복수로 형성된 것을 나타낸 것으로서, 음파는 서로 다른 흡음공(5)을 통과하면서 각각 회절되게 되고, 이 두 음파가 회절되면서 서로 중첩되어 간섭을 일으키게 된다.Meanwhile, FIG. 4 illustrates that a plurality of sound absorbing holes 5 are formed in one cell 15, and sound waves are diffracted while passing through different sound absorbing holes 5, and the two sound waves are diffracted and overlapped with each other. Will cause interference.

또한 회절되어 진행하는 두 음파는 서로 다른 경로를 통해 셀(15) 내부의 벽면에 반사되어 진행하면서 서로 간섭되게 되어 소리의 크기가 감소되거나 또는 서로 상쇄되어 소멸되게 되는 것이다.In addition, the two sound waves are diffracted and reflected on the wall surface inside the cell 15 through different paths, and are interfered with each other so that the volume of sound is reduced or canceled out.

따라서 본 발명은 외부의 소음이 타공판(1)의 흡음공(5)을 통해 유입된 후, 회절과 간섭현상 등에 의해 소음의 크기가 감소되거나 소멸되게 됨으로써, 별도의 고가의 흡음패널이나 방음패널을 사용하거나, 또는 흡음재나 차음재를 충진, 코팅하지 않고도 효과적으로 소음을 흡수 차단시킬 수 있게 되는 것이다.Therefore, in the present invention, after the external noise is introduced through the sound absorbing hole 5 of the perforated plate 1, the noise is reduced or extinguished by diffraction and interference, and thus, a separate expensive sound absorbing panel or soundproof panel is obtained. It is possible to effectively absorb and block the noise without using or filling and coating the sound absorbing material or sound insulating material.

이상, 상기의 실시 예는 단지 설명의 편의를 위해 예시로서 설명한 것에 불과하므로 특허청구범위를 한정하는 것은 아니다.As described above, the above embodiments are merely described as examples for convenience of description and are not intended to limit the scope of the claims.
