상기한 바와 같은 구성을 갖는 본 고안의 작용을 설명한다.The operation of the present invention having the configuration as described above will be described.

우선 두 개 이상의 플라스틱 패널을 세워 좌, 우측면을 일치하도록 한 후, 상기 패널 본체의 좌측면에 형성된 좌측 끼움결합부(34)를 다른 패널 본체의 우측면에 형성된 우측 끼움결합부(44)에 끼움 결합한다.First, two or more plastic panels are erected so that the left and right sides are coincident with each other, and then the left fitting portion 34 formed on the left side of the panel body is fitted to the right fitting portion 44 formed on the right side of the other panel body. do.

이러한 결합 형태를 지속하여 다수 개의 플라스틱 패널이 펜스를 이루도록 형성한 후, 상기 결합 부분을 클램프(70)를 사용하여 체결한다. 이때 클램프(70)의 절곡된 종단면이 패널 본체의 좌우측면에 형성된 좌, 우측 걸림결합부(36, 46)의 좌, 우측 경사부(38, 48)에 걸림되며 양 패널 본체를 견고히 고정하게 된다.This coupling form is continued to form a plurality of plastic panels to form a fence, and then the coupling portion is fastened using the clamp 70. At this time, the bent longitudinal section of the clamp 70 is caught by the left and right inclined portions 38 and 48 of the left and right engaging portions 36 and 46 formed on the left and right sides of the panel body, thereby firmly fixing both panel bodies. .

상기 클램프(70)는 펜스의 중간에 설치된 폴대 등에 다른 고정수단에 의해 고정됨으로서 플라스틱 패널의 전도를 방지하게 된다.The clamp 70 is fixed by another fixing means such as a pole installed in the middle of the fence to prevent the plastic panel from falling.

또한 상기 플라스틱 패널의 패널 본체(10)와 덮개 결합부재(50) 사이에 형성되는 공간에 덮개(60)를 상방향에서 하방향으로 삽입하는 형태로 결합하는바, 이때 덮개에 형성된 걸림돌부가 상기 덮개 결합부재(50)의 중앙방향 절곡부의 상단면에 형성된 끼움홈에 끼움결합되면서 그 고정력을 높이게 된다.In addition, the cover 60 is inserted into the space formed between the panel body 10 and the cover coupling member 50 of the plastic panel in the form of inserting from the upper direction to the lower direction, in this case the locking protrusion formed on the cover The fixing force is increased while being fitted into the fitting groove formed on the upper surface of the central bending portion of the coupling member 50.

또한 차음의 효과를 높이기 위해서 상기 플라스틱 패널 본체(10)와 덮개(60) 사이에 고무, 스펀지 등의 충진재를 개재할 수 있다.In addition, a filler such as rubber or sponge may be interposed between the plastic panel body 10 and the cover 60 in order to increase the sound insulation effect.

본 고안에 의하면, 차음용 펜스를 구성하는 플라스틱 패널 자체에 차음을 위한 공동이 구비되며, 경우에 따라서는 차음을 위한 충진재를 개재시킬 수 있도록 구성되어 차음 효과의 극대화를 이룰 수 있다.According to the present invention, a cavity for sound insulation is provided in the plastic panel itself constituting the fence for sound insulation, and in some cases, it is configured to interpose a filler for sound insulation, thereby maximizing the sound insulation effect.

또한 본 고안에 의하면, 패널 본체의 좌우측 종단면에 형성된 끼움부재로 인해 강한 결합력을 유지할 수 있으므로 시공시는 물론 사용시의 전도 가능성을 현저히 감소시키는 효과가 있다.In addition, according to the present invention, it is possible to maintain a strong bonding force due to the fitting member formed on the left and right longitudinal cross-section of the panel body has the effect of significantly reducing the possibility of conduction during use as well as during construction.

본 고안에 의하면 각각의 패널 본체를 끼움 결합에 의해 결합시킴은 물론 양단에 형성된 걸림부재에 클램프를 이용하여 걸림 결합을 이중으로 함으로써 패널 간의 결합력을 증대함은 물론 상기 클램프를 폴대 등에 별도의 고정수단을 이용하여 재차 고정함으로써 간단한 설비와 그에 따른 간편한 시공에 의해서도 견고한 고정력을 유지하는 효과를 거둘 수 있다.According to the present invention, each panel main body is coupled by fitting, as well as double locking by using a clamp on the engaging members formed at both ends, thereby increasing the bonding force between the panels, as well as a separate fixing means for the pole and the like. By fixing it again, it is possible to obtain the effect of maintaining a firm fixing force even by simple installation and simple construction.
