Description

방음패널 및 그 제조방법{SOUNDPROOF PANEL AND METHOD FOR MANUFACTURING THE SAME}Soundproof panel and its manufacturing method {SOUNDPROOF PANEL AND METHOD FOR MANUFACTURING THE SAME}

본 발명은 방음패널 및 그 제조방법에 관한 것으로서, 보다 상세하게는 구조가 단순하고 코스트가 절감되면서도 효과적인 방음이 가능하도록 개선된 방음패널 및 그 제조방법에 관한 것이다.The present invention relates to a soundproof panel and a method of manufacturing the same, and more particularly, to a soundproof panel improved to enable effective sound insulation while having a simple structure and reduced cost, and a manufacturing method thereof.

예컨대, 건설현장에서는 공사 관련한 소음이 심하게 발생하며, 이러한 소음은 현장 주변에 위치한 주택, 사무실 또는 학교 등에 심각한 소음 공해를 유발하게 된다. For example, construction-related noise is severely generated at a construction site, and this noise causes serious noise pollution in houses, offices, or schools located around the site.

특히, 공사현장이 도로변에 위치한 경우 공사소음이 차량 소음과 합세하여 사람들에게 엄청난 스트레스를 주게 된다.In particular, when the construction site is located on the side of the road, the construction noise is combined with the vehicle noise, which places great stress on people.

이렇게 건설현장에서 발생하는 소음을 차단하고 보행자의 안전을 위하여 공사가 진행되는 동안 가설 방음벽(또는 방음판)을 설치하게 되며, 공사가 완료된 후, 상기 가설 방음벽을 철거하게 된다.In this way, for the safety of pedestrians and to block noise generated at the construction site, a temporary sound insulation wall (or sound insulation board) is installed during construction, and after the construction is completed, the temporary sound insulation wall is removed.

이러한 가설 방음벽은 공사현장에서 한시적으로 설치하여 사용하는 것으로, 설치 및 철거가 용이하여야 하고 설치에 따른 견고성을 필요로 한다.These temporary soundproof walls are temporarily installed and used at the construction site, and must be easy to install and remove, and require robustness according to the installation.

상기와 같은 가설 방음벽이 공개특허 제10-2010-0127445호(2010. 12. 06일 공개)에 개시되어 있다.A temporary soundproofing wall as described above is disclosed in Korean Patent Publication No. 10-2010-0127445 (published on December 06, 2010).

그런데, 상기한 공개특허의 가설 방음벽은, 흡음시트 및 흡음판의 구조가 소음을 효과적으로 흡음할 수 있는 구조가 아니다.By the way, in the temporary sound insulation wall of the above disclosed patent, the structure of the sound absorbing sheet and the sound absorbing plate is not a structure capable of effectively absorbing noise.

즉, 흡음시트의 경우 단순한 수지로 이루어진 것이 전부이고, 상기 흡음판의 경우에도 복수의 블록곡면 및 오면곡면이 연속하여 형성되어 소음이 블록곡면 및 오면곡면에서 흡음되거나 상쇄된다고 했지만, 상기 블록곡면 및 오면곡면의 구조상 소음이 흡음되거나 상쇄되기 어렵거나 효과가 미미한 구조이다.That is, in the case of the sound-absorbing sheet, it is all made of a simple resin, and even in the case of the sound-absorbing plate, a plurality of block and five-sided curves are formed in succession, so that noise is absorbed or canceled at the block and five-sided curves. Due to the structure of the curved surface, it is difficult to absorb or cancel the noise, or the effect is insignificant.

또한, 공개특허의 가설 방음벽은, 흡음시트 및 흡음판을 끼움리브와 체결부재를 통해 체결하는 구조이어서 구성 및 구조가 복잡하고, 이에 따라 가설 방음벽의 설치 및 철거가 용이하지 않으며, 비용이 증가된다.In addition, the temporary soundproofing wall of the public patent is a structure in which the sound-absorbing sheet and the sound-absorbing plate are fastened through a fitting rib and a fastening member, so the construction and structure are complicated, and accordingly, it is not easy to install and remove the temporary sound-proof wall, and the cost is increased.

상기와 같은 문제점을 해결한 가설 방음벽이 등록실용신안 제20-0483000호(2017년 03월 20일, 등록)에 개시되어 있다.A temporary soundproof wall that solves the above problems is disclosed in Utility Model Registration No. 20-0483000 (registered on March 20, 2017).

상기한 등록실용신안의 가설 방음벽은, 방음패널의 후면의 구조를 개선하여 소음이 효과적으로 흡음이 되도록 하였으며, 흡음이 적절하게 소거되도록 하여 소음이 방음패널 외부로 새어 나가는 것을 차단하거나 최소화가 되도록 하였다.The temporary soundproof wall of the above registered utility model has improved the structure of the rear surface of the soundproof panel so that noise is effectively absorbed, and the sound absorption is properly eliminated to prevent or minimize the leakage of noise to the outside of the soundproof panel.

또한, 등록실용신안의 가설 방음벽은, 방음패널의 구성이 매우 단순하고, 방음패널에 흡음부재가 삽입 설치되도록 하여, 전체적인 방음벽의 구성 및 구조가 단순해졌고, 특히 흡음부재가 방음패널에 형성된 개원형부의 일측면에서 끼워지도록 하여 조립 및 해체가 쉽고, 자재비가 절감된다.In addition, for the temporary soundproof wall of the registered utility model, the construction of the soundproof panel is very simple, and the sound absorption member is inserted and installed in the soundproof panel, so that the overall construction and structure of the soundproof wall is simplified. It is easy to assemble and disassemble by being fitted on one side of the product, and material cost is reduced.

따라서 등록실용신안의 가설 방음벽은, 소음 차단 효과가 우수하고, 가설 방음벽의 설치 및 철거가 용이하며, 비용 절감이 가능해졌다.Therefore, the temporary sound insulation wall of the registered utility model has excellent noise blocking effect, easy installation and removal of the temporary sound insulation wall, and cost reduction.

하지만, 등록실용신안의 가설 방음벽은, 방음패널 자체에 흡음수단이 형성되어 있지 않고, 상기 방음패널에 봉 형태의 스펀지로 이루어진 흡음부재를 삽입 설치하여 흡음 효과가 이루어지도록 하였다.However, in the temporary sound insulation wall of the registered utility model, a sound absorption means is not formed in the sound insulation panel itself, and a sound absorption member made of a rod-shaped sponge is inserted into the sound insulation panel to achieve a sound absorption effect.

이에 따라 상기한 등록실용신안의 가설 방음벽의 방음패널은 흡음부재를 삽입하기 위해 라운드 형태의 개원형부를 형성하는데, 이 개원형부의 형성으로 방음패널의 구조가 복잡하여 이 방음패널의 압출금형 비용이 고가이며, 방음패널의 압출성형이 용이하게 이루어지지 않는다.Accordingly, the soundproof panel of the temporary soundproof wall of the registered utility model forms a round-shaped open-shaped part to insert the sound-absorbing member, and the structure of the sound-proof panel is complicated due to the formation of this open-shaped part. The cost of the extrusion mold for the soundproof panel is expensive, and the extrusion molding of the soundproof panel is not easily performed.

또한, 별도의 스펀지로 이루어진 흡음부재를 개원형부에 삽입하여야 하기 때문에 별도의 흡음부재 삽입공정이 이루어져야 하기 때문에 작업인원이 많이 소요되며, 스펀지의 특성상 삽입이 용이하지 않으며, 쉽게 흡음부재가 개원형부에서 이탈된다.In addition, since the sound-absorbing member made of a separate sponge must be inserted into the open-circular part, a separate sound-absorbing member inserting process must be performed, so it takes a lot of workforce, and it is not easy to insert due to the nature of the sponge, and the sound-absorbing member is easily inserted in the open-circular part. Deviated.

그리고 상기한 등록실용신안의 가설 방음벽은, 전술한 바와 같이, 방음패널 자체에 흡음수단이 없기 때문에 상기 흡음부재가 개원형부에 제대로 설치되지 않으면 흡음 효과를 달성하기 어렵다.And, as described above, the temporary sound-absorbing wall of the registered utility model does not have a sound-absorbing means in the sound-insulating panel itself, and thus it is difficult to achieve a sound-absorbing effect if the sound-absorbing member is not properly installed in the open-circular portion.

이와 같이 종래의 기술인 등록실용신안의 가설 방음벽은, 방음패널의 구조상 별도의 흡음부재의 설치로 가설 방음벽의 코스트가 증가되고, 원하는 흡음 및 방음 효과를 달성하기 어려우며, 철거 또한 용이하지 않으며, 스펀지로 이루어진 흡음부재의 제품관리(또는 자재관리)가 어렵다.As described above, the temporary soundproofing wall of the registered utility model, which is a conventional technology, increases the cost of the temporary soundproofing wall due to the installation of a separate sound absorption member due to the structure of the soundproof panel, it is difficult to achieve the desired sound absorption and sound insulation effect, and it is not easy to dismantle. Product management (or material management) of the sound-absorbing member made is difficult.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 방음패널 자체에 흡음수단이 채용되어 있어 별도의 흡음부재가 필요하지 않으며, 방음패널 구조가 단순하여 코스트가 절감되도록 한 방음패널 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention was created to solve the above problems, and a sound-absorbing means is adopted in the sound-proof panel itself, so that a separate sound-absorbing member is not required, and the sound-proof panel and its manufacturing are made to reduce cost due to the simple sound-proof panel structure. Its purpose is to provide a method.

Consists of

상기한 바와 같이, 흡음수단(110,120)이 절개부(112a,112b,122a,122b)의 형성에 의해 흡음개구(113a,113b,123a,123b)가 형성되되, 소정 각도(예컨대, 45도)로 경사지며 형성되며, 이 흡음개구(113a,113b,123a,123b) 및 절개부(112a,112b,122a,122b)가 소정 거리인 이격부(111,121)를 두고 형성된다.As described above, the sound-absorbing means (110, 120) is formed by the formation of the cutouts (112a, 112b, 122a, 122b), the sound-absorbing openings (113a, 113b, 123a, 123b) are formed, at a predetermined angle (for example, 45 degrees). It is formed to be inclined, and the sound-absorbing openings 113a, 113b, 123a, 123b and the cutouts 112a, 112b, 122a, 122b are formed with spaced portions 111 and 121 having a predetermined distance.

그리고 상기 흡음개구(113a,113b,123a,123b)가 가로 방향과 세로 방향에 각각 가로 흡음개구(123a,123b)와 세로 흡음개구(113a,113b)로 구분되며 형성된다.In addition, the sound-absorbing openings 113a, 113b, 123a, and 123b are divided into horizontal sound-absorbing openings 123a and 123b and vertical sound-absorbing openings 113a and 113b in the horizontal and vertical directions, respectively.

즉, 흡음개구(113a,113b,123a,123b)가 상기 이격부(111,121)를 두고 형성됨으로써, 흡음개구(113a,113b,123a,123b)가 완전한 개구 또는 홀로 형성된 것에 비해 약 2배가량 더 많은 수의 흡음개구(113a,113b,123a,123b)를 형성할 수 있고, 사방(또는 모든 방향)을 향해 절개부(112a,112b,122a,122b)가 형성됨으로써, 사방(또는 모든 방향)에서 소음을 흡음할 수 있다.That is, the sound-absorbing openings 113a, 113b, 123a, 123b are formed with the spaced portions 111, 121, so that the sound-absorbing openings 113a, 113b, 123a, 123b are about twice as much as those formed as complete openings or holes. It is possible to form a number of sound absorption openings (113a, 113b, 123a, 123b), and by forming cutouts (112a, 112b, 122a, 122b) in all directions (or all directions), noise in all directions (or all directions) Can be absorbed.

따라서 소음을 더 효과적으로 흡음할 수 있다.Therefore, noise can be absorbed more effectively.

또한, 상기 절개부(112a,112b,122a,122b)를 형성하되, 소정 각도(예컨대, 45도)로 경사지게 형성함으로써, 도 2에 도시된 바와 같이, 소음을 경사진 절개부(112a,112b,122a,122b)에 충돌시키면서 흡음할 수 있어 흡음공간(104)에서 넓게 퍼지는 동시에 오래 머무를 수 있다.In addition, by forming the cutouts 112a, 112b, 122a, and 122b, but by forming the cutouts 112a, 112b, 122a, and 122b to be inclined at a predetermined angle (for example, 45 degrees), as shown in FIG. 2, the cutouts 112a, 112b, inclined noise, 122a, 122b) can be absorbed while colliding with each other, so that it can be spread widely in the sound-absorbing space 104 and stay for a long time.

이에 따라 흡음공간(104)으로 흡음된 소음은 흡음공간(104) 내에서 용이하게 소멸시킬 수 있다.Accordingly, noise absorbed into the sound-absorbing space 104 can be easily extinguished within the sound-absorbing space 104.

그리고 상기 절개부(112a,112b,122a,122b)가 형성된 흡음개구(113a,113b,123a,123b)를 가로 방향과 세로 방향으로 다르게 형성함으로써, 상기 절개부(112a,112b,122a,122b)가 사방 방향을 향해 형성되어 있다.And by forming the sound-absorbing openings 113a, 113b, 123a, 123b in which the cutouts 112a, 112b, 122a, 122b are formed differently in a horizontal direction and a vertical direction, the cutouts 112a, 112b, 122a, 122b It is formed in all directions.

즉, 가로 흡음개구(123a,123b)의 절개부(122a,122b)와 세로 흡음개구(113a,113b)의 절개부(112a,112b)는 직교되게 형성되어 있다.That is, the cutouts 122a and 122b of the horizontal sound absorption openings 123a and 123b and the cutouts 112a and 112b of the vertical sound absorption openings 113a and 113b are formed to be orthogonal.

따라서 사방 방향(또는 모든 방향)에서 소음을 흡음할 수 있어, 효과적인 또는 최적인 흡음이 가능하여, 방음패널(100)의 소음 차단 효과가 극대화된다.Accordingly, noise can be absorbed in all directions (or all directions), so that effective or optimal sound absorption is possible, so that the noise blocking effect of the soundproof panel 100 is maximized.

또한, 본 발명에 따른 방음패널(100)은 상기한 바와 같이, 기존의 방음패널과 달리 방음패널(100) 하나로만 가설 방음벽을 형성할 수 있어, 가설 방음벽 구성이 간단하고 설치 및 해체가 용이하며, 코스트를 대폭적으로 절감시킬 수 있다.In addition, as described above, the sound insulation panel 100 according to the present invention can form a temporary sound insulation wall with only one sound insulation panel 100, unlike the existing sound insulation panel, so that the construction of the temporary sound insulation wall is simple, and installation and disassembly are easy. And, the cost can be drastically reduced.

특히, 본 발명에 따른 방음패널(100)이 PVC로 압출성형 되었기 때문에 코스트 절감 효과가 매우 크고, 경량이기 때문에 취급이 매우 용이하여 가설 방음벽의 설치 및 해체에 유리하다.In particular, since the sound insulation panel 100 according to the present invention is extruded from PVC, the cost reduction effect is very large, and because it is lightweight, it is very easy to handle, which is advantageous for installation and dismantling of the temporary sound insulation wall.

상기한 바와 같은 구성을 갖는 본 발명에 따른 방음패널의 제조방법을 설명하면 다음과 같다.A method of manufacturing a soundproof panel according to the present invention having the configuration as described above will be described as follows.

또한, 도 7에는 도 5의 성형금형에 의해 흡음수단이 성형된 방음패널의 요부 상세도가 도시되어 있다.In addition, Fig. 7 is a detailed view of the main parts of the sound-absorbing panel formed by the molding mold of Fig. 5.

도 1 내지 도 7을 참조하면, 본 발명에 따른 방음패널 제조방법은, 우선, 도 3과 도 4에 도시된 바와 같이, 외부판(101)과 내부판(103)이 일체가 되게 길이 방향으로 일정 간격마다 외부판(101)과 내부판(103)을 격벽(102)으로 연결하고, 상기 격벽(102)에 의해 내부판(103)과 외부판(101) 사이에 연속하여 빈 공간(104a)을 형성한 방음패널(100b)을 압출기의 압출금형(5)에서 압출성형한다.(단계 10)1 to 7, the method of manufacturing a soundproof panel according to the present invention, first, as shown in FIGS. 3 and 4, in the longitudinal direction so that the outer plate 101 and the inner plate 103 are integrated. The outer plate 101 and the inner plate 103 are connected by a partition wall 102 at regular intervals, and an empty space 104a continuously between the inner plate 103 and the outer plate 101 by the partition wall 102 The soundproof panel (100b) formed by the extruder is extruded in the extrusion mold (5) of the extruder. (Step 10)

한편, 도 3에서 도면번호 1은 압출성형기이고, 2는 압출성형기(1)의 본체이며, 3은 압출성형기(1)에 재료(플라스틱 수지)를 공급하는 호퍼(hopper)이고, 4는 압출성형기(1)의 실린더를 나타내 보인 것이다.On the other hand, in FIG. 3, reference numeral 1 is an extrusion molding machine, 2 is the main body of the extrusion molding machine 1, 3 is a hopper that supplies a material (plastic resin) to the extrusion molding machine 1, and 4 is an extrusion molding machine. It shows the cylinder of (1).

이어서, 도 3 내지 도 6에 도시된 바와 같이, 압출성형된 방음패널(100b)을 성형금형(200) 하부로 통과시켜 방음패널(100b)의 빈 공간(104a)과 연통되게 하여 빈 공간(104a)이 공사장 등으로부터 발생되는 소음을 흡수하는 도 7의 흡음공간(104)이 되도록 내부판(103)의 전체면에 흡음수단(110,120)을 형성한다.(단계 20)Subsequently, as shown in FIGS. 3 to 6, the extruded soundproof panel 100b is passed under the molding mold 200 to communicate with the empty space 104a of the soundproof panel 100b, and thus the empty space 104a ) To form the sound-absorbing means (110, 120) on the entire surface of the inner plate (103) so that the sound-absorbing space (104) of Figure 7 absorbs the noise generated from the construction site. (Step 20)

보다 구체적으로는, 사출성형된 방음패널(100b)이 성형금형(200)의 하부로 이송되면서 가공이 되도록 상기 성형금형(200)의 하부에는 측방 돌출부(106,107) 및 중앙 돌출부(105)가 끼워져 방음패널(100b)이 안정적으로 지나도록 가이드 홈(220,230,240)이 형성되어 있다.More specifically, the lateral protrusions 106 and 107 and the central protrusion 105 are inserted into the lower part of the molding mold 200 so that the injection-molded soundproof panel 100b is transferred to the lower part of the molding mold 200 and processed. Guide grooves 220, 230, and 240 are formed so that the panel 100b stably passes.

이러한 가이드 홈(220,230,240)의 형성으로 방음패널(100b)을 위치 변형 없이 이송시킬 수 있어 후공정 진행에 유리하며, 흡음수단(110,120)을 정확한 위치에 성형할 수 있다.With the formation of the guide grooves 220, 230, and 240, the soundproof panel 100b can be transferred without any change in position, which is advantageous for the progress of the post-process, and the sound absorbing means 110 and 120 can be molded in the correct position.

그리고 상기 성형금형(200)의 가장자리 하부에는 성형금형(200)의 펀치(210)가 승강 작동시 성형금형(200)을 지지하는 지지부(200a)가 구비되어 있다.In addition, a support part 200a for supporting the molding mold 200 is provided under the edge of the molding mold 200 when the punch 210 of the molding mold 200 moves up and down.

상기와 같이 구성되고, 일정 간격으로 다수 개의 펀치(210)가 구비된 성형금형(200)으로 이송된 방음패널(100b)의 내부판(103)에 상기 펀치(210)의 작용에 의해 흡음수단(110,120)이 가공된다.Sound absorbing means by the action of the punch 210 on the inner plate 103 of the soundproof panel 100b transferred to the molding mold 200 provided with a plurality of punches 210 at regular intervals ( 110,120) are processed.

즉, 상기 펀치(210)의 본체(211) 내부에는 히터(213)가 수직으로 구비되어 있어, 상기 흡음개구(113a,113b,123a,123b) 가공시 상기 내부판(103)을 소정 온도로 가열하며 가공한다.That is, the heater 213 is vertically provided inside the main body 211 of the punch 210, so that the inner plate 103 is heated to a predetermined temperature when processing the sound absorption openings 113a, 113b, 123a, 123b. And process it.

또한, 상기 펀치(210)의 하면 중앙은 오목한 라운드(R) 형태로 형성된다.In addition, the center of the lower surface of the punch 210 is formed in a concave round (R) shape.

이러한 구성으로 이루어진 펀치(210)가 하강되면서 상기 히터(213)가 PVC로 이루어진 내부판(103)을 약 180℃ 전후로 가열하는 동시에 펀칭(또는 가압) 작용을 하여 내부판(103)의 일부가 절개되어 흡음공간(104)으로 돌출되게 절개부(112a,112b,122a,122b)를 형성한다.As the punch 210 made of this configuration is lowered, the heater 213 heats the inner plate 103 made of PVC to about 180° C. and at the same time performs a punching (or pressurization) action to cut a part of the inner plate 103 The cutouts 112a, 112b, 122a, and 122b are formed so as to protrude into the sound-absorbing space 104.

또한, 상기 절개부(112a,112b,122a,122b)가 형성되되 흡음공간(104)으로 돌출 형성되므로, 흡음공간(104)과 연통되게 흡음개구(113a,113b,123a,123b)가 형성된다.In addition, since the cutouts 112a, 112b, 122a, and 122b are formed but protrude into the sound-absorbing space 104, sound-absorbing openings 113a, 113b, 123a, and 123b are formed to communicate with the sound-absorbing space 104.

이렇게 흡음개구(113a,113b,123a,123b)를 일부만 형성한 이유는 절개부(112a,112b,122a,122b)를 형성하기 위한 것이다.The reason why the sound-absorbing openings 113a, 113b, 123a, and 123b are partially formed is to form the cutouts 112a, 112b, 122a, and 122b.

그리고 히터(213)를 이용한 것은 PVC 소재 특성상 펀치(210)의 펀칭(또는 가압) 작용에 의해서만은 원하는 또는 도면에 도시된 바와 같은 형상의 흡음개구(113a,113b,123a,123b)를 성형하기 어렵기 때문이다.And it is difficult to mold the sound-absorbing openings 113a, 113b, 123a, 123b of the shape as shown in the drawing or desired only by the punching (or pressing) action of the punch 210 due to the characteristics of the heater 213 Because.

따라서 상기 흡음개구(113a,113b,123a,123b) 성형시 펀치(210)는 내부판(103)에 대하여 타발(또는 커팅) 및 가열, 그리고 펀칭 작용을 동시에 한다.Therefore, when forming the sound-absorbing openings 113a, 113b, 123a, 123b, the punch 210 performs punching (or cutting), heating, and punching for the inner plate 103 at the same time.

또한, 상기 펀치(210)의 하면 중앙을 오목한 라운드(R)를 형성한 이유는, 흡음개구(113a,113b,123a,123b)를 완전한 구멍(또는 홀)을 형성하지 않도록 하기 위해서이다.In addition, the reason why the round R in which the center of the lower surface of the punch 210 is concave is formed is to prevent the sound absorption openings 113a, 113b, 123a, and 123b from forming complete holes (or holes).

이에 따라 상기 펀치(210)의 오목한 라운드(R)의 형성에 의해 펀치(210)의 가장자리에 돌출부(211a)가 형상된다.Accordingly, a protrusion 211a is formed at the edge of the punch 210 by forming the concave round R of the punch 210.

이때, 상기 돌출부(211a)는 높이를 달리하여 형성해도 된다.In this case, the protrusion 211a may be formed with a different height.

따라서 상기 돌출부(211a)의 펀칭 작용에 의해 절개부(112a,112b,122a,122b)가 형성되고, 형성된 절개부(112a,112b,122a,122b)를 하방으로 눌러 상기 절개부(112a,112b,122a,122b)가 흡음공간(104)을 향하여 소정 각도(예컨대, 45도)로 경사지며 형성되게 된다.Therefore, the cutouts 112a, 112b, 122a, 122b are formed by the punching action of the protrusion 211a, and the cutouts 112a, 112b, by pressing the formed cutouts 112a, 112b, 122a, 122b downward, 122a and 122b are formed to be inclined toward the sound-absorbing space 104 at a predetermined angle (eg, 45 degrees).
