또, 포스트의 상부에 회절음 감쇄구의 각도로 받침대를 형성하여 회절름 감쇄구를 받쳐주면서 밴드로 결속하여 설치함을 특징으로 한다.In addition, the pedestal is formed on the upper portion of the post at the angle of the diffraction sound attenuator, characterized in that it is provided by binding to the band while supporting the diffraction damper.

이하, 본 발명을 첨부한 바람직한 실시예의 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the preferred embodiment of the present invention.

도 2는 본 발명의 전체구성을 도로 외측에서 본 사시도이고, 도 3은 본 발명의 전체 단면도이고, 도 4은 본 발명의 회절음 감쇄구 정면도이고, 도 5는 본 발명에서의 록크심부 확대 단면도이고, 도 6은 회절름 감쇄구의 한측부의 확대 단면도이다.Figure 2 is a perspective view of the entire configuration of the present invention seen from the outside of the road, Figure 3 is an overall cross-sectional view of the present invention, Figure 4 is a front view of the diffraction sound attenuator of the present invention, Figure 5 is an enlarged cross-sectional view of the lock core portion in the present invention 6 is an enlarged cross-sectional view of one side of the diffraction damping sphere.

먼저 방음벽(1)의 기본적인 전체구성을 살펴보면,First, look at the basic overall configuration of the soundproof wall (1),

적정간격을 두고 설치되는 포스트(10)와, Post 10 is installed at a suitable interval,

포스트(10)의 사이에 다단으로 설치되는 방음틀(20)과, Sound insulation frame 20 which is installed in multiple stages between the posts 10,

방음틀(20)에는 내부에 흡음재(40)가 부착된 상태로 설치되는 방음판(30)과,In the soundproofing frame 20, the soundproof plate 30 is installed in a state in which the sound absorbing material 40 is attached therein,

방음틀(20)의 상단에는 회절음을 제어히도록 설치되는 회절음 감쇄구(50),The diffraction sound attenuation opening 50 is installed on the top of the sound insulation frame 20 to control the diffraction sound,

로 이루어진다.Is made of.

본 발명에서 설명하고자 하는 회절음 감쇄구(50)의 구성을 살펴보면(첨부도면에서 종래의 구성과 동일한 구성에 대하여는 동일 부호를 부여하여 설명한다),Looking at the configuration of the diffraction sound attenuator 50 to be described in the present invention (the same configuration as the conventional configuration in the accompanying drawings will be described with the same reference numerals),

도 4에서와 같이 띠형태의 판재가 나선방향으로 감으면서 판재사이를 록크심(Lock seam)(54)하여 원형 관체를 성형한 후 오한 내면판(51)과 흡음공(56)을 형성한 외면판(52)을 각각 형성한다. As shown in FIG. 4, the outer surface is formed with a chill inner plate 51 and a sound absorbing hole 56 after the belt-shaped plate is wound in a spiral direction to form a circular tube by locking seams 54 between the plates. Each plate 52 is formed.

상기 록크 심(54)의 이음부는 판재가 다수면 적층된 상태이기 때문에 두텁고 견고하면서 나선방향으로 형성되어져 관체에 보강대 역활을 수행하여 강도를 높일 수 있어 제작시 판재를 기존의 판재 두께보다 상당히 얇은 판재를 사용하여도 요구하는 강도 이상의 효과를 갖는다.Since the joints of the lock shim 54 are plated in a state where a large number of plates are stacked, they are formed in a thick, solid and helical direction to increase the strength by acting as a reinforcing rod on the pipe, and thus the plate is significantly thinner than the thickness of the existing plate. Even when using, it has an effect more than the intensity | strength required.

판재를 감아 성형하는 내면판(51)과 외면판(52)의 성형은 스파이럴 성형기에 의하여 성형될 수 있고, 상기 록크 심이란 판과 판을 리벳이나 용접없이 서로 예각으로 절곡시키어 갈고리모양으로 조합시키어 시링하여 이음하는 방법이다. Molding of the inner plate 51 and the outer plate 52 for winding the sheet material can be molded by a spiral molding machine, the lock shim is a plate and the plate is bent at an acute angle to each other without rivets or welding to combine the hook shape It is a method of seaming by seaming.

그리고 상기 내면판(51)에 흡음재(53)를 부착한 후 외면판(52)과 결합한 후 양측단을 마감판(55)을 체결, 고정하여 회절음 감쇄구(50)를 구성한다.Then, the sound absorbing material 53 is attached to the inner surface plate 51 and then coupled with the outer surface plate 52 to fasten and fix both ends of the closing plate 55 to form a diffraction sound attenuation port 50.

상기 회절음 감쇄구(50)를 부채꼴 형상등으로 형성하는데 이는 원형으로 나온 내면판(51)과 외면판(52)을 오발(Oval)성형기등에 의하여 다양한 형상으로 형성할 수 있다. The diffractive sound attenuator 50 is formed in a fan shape, etc., which may be formed in various shapes by using an Oval molding machine such as an inner plate 51 and an outer plate 52 which are circular.

한편, 회절음 감쇄구(50)를 포스트(10)의 상부에 설치하기 위한 수단으로, 포스트(10)의 상단에 회절음 감쇄구(50)의 각도로 받침대(11)를 연장되게 형성하여 회절름 감쇄구를 받칠 수 있도록 하면서 밴드(60)로 결속하여 고정, 설치한 것이다.On the other hand, as a means for installing the diffraction sound attenuator 50 on the top of the post 10, the pedestal 11 is formed to extend on the top of the post 10 at the angle of the diffraction sound attenuator 50 to diffraction It is fixed and installed by binding to the band (60) while supporting the oil attenuation openings.

이와 같이 구성되는 본 발명은 내,외면판을 스파이럴 성형기 및 오발 성형기에 의하여 연속적으로 성형하여 원하는 형상으로 제작될 수 있어 제작공정을 단순화 할 수 있는 구성을 갖고, 소재를 기존 방음벽에 사용되는 알루미늄 소재를 사용할 수 있어 기존 방음벽과 조화를 이룰 수 있다.The present invention configured as described above can be manufactured in a desired shape by continuously forming the inner and outer plates by a spiral molding machine and an overmolding machine, so that the manufacturing process can be simplified, and the material is an aluminum material used for an existing soundproof wall. Can be used in harmony with the existing sound barrier.

특히 회절음 감쇄구의 형상을 부채꼴 형상을 이루고 있어 외부면적이 급경사를 이루면서 면적이 극대화되어 도로에서 발생되는 소음이 급경사면을 부딪치면서 무수한 타공을 통해 흡수되면서 제거되어 상단부를 타고 넘어가는 회절음파를 막아주어 방음효율을 대폭적으로 향상할 수 있게 하는 것이다.In particular, the shape of the diffraction sound attenuator has a fan-shaped shape, and the outer area is steeply inclined, maximizing the area, and the noise generated on the road hits the steep slope and is absorbed through countless perforations, preventing the diffraction sound passing over the upper part. It is possible to greatly improve the sound insulation efficiency.

이상과 같이 본 발명은 회절음 감쇄구의 제작공정의 간편화와, 기존보다 낮은 두께로 강한 강도를 얻을 수 있어 제작단가를 대폭적으로 절감할 수 있고, 외형리 부체꼴 형상으로 인하여 회절음 감쇄 효과를 극대화 할 수 있으면서 미려한 효과 등이 있다.As described above, the present invention can simplify the manufacturing process of the diffraction sound attenuation sphere, and can obtain a strong strength with a lower thickness than the conventional one, which can greatly reduce the production cost, and maximize the diffraction sound attenuation effect due to the externally shaped floating body. It can be done but has a beautiful effect.
