본 발명은 트러스 구조체에 관한 것으로, 보다 상세하게는 설치면과 수직으로 설치되는 복수개의 수직브레싱과, 상기 수직브레싱과 수직브레싱의 상부에 위치하여 설치되는 수평트러스구조체로 구성되는 조립식 트러스 구조체에 있어서, 상기 연결부재의 내부에 스피커가 결합되고, 상기 스피커의 설치방향으로 스피커음이 정확히 전달될 수 있도록 일면에 연옥분말 코팅층이 형성된 스피커음 손실방지부재가 다수개 구비되어 있는 일면에 연옥분말 코팅층이 형성된 스피커음 손실방지부재가 구비된 전시용 조립식 트러스 구조물의 연결부재에 관한 것이다. The present invention relates to a truss structure, and more specifically, to a prefabricated truss structure consisting of a plurality of vertical brass vertically installed on the mounting surface, and a horizontal truss structure positioned above the vertical brass and vertical brass. , A nephrite powder coating layer is formed on one surface of which a speaker sound loss prevention member is formed on one side so that a speaker is coupled to the inside of the connecting member and the speaker sound is accurately transmitted in the installation direction of the speaker.

일반적으로 전시장이나 행사장 등에서는 그 전시 및 행사의 효과를 높이기 위해 각종의 조명이나 전시물을 설치하기 위한 구조물이 요구된다. 이 경우 통상적으로 스테인레스나 알루미늄 등의 소재로 제작된 포스트 및 트러스를 이용하여 연결부재 내지는 클램프를 통해 고정체결함으로써 다양한 형태의 트러스 구조물을 제작함이 일반적이다. In general, a structure for installing various lightings or exhibits is required in an exhibition hall or an event hall in order to increase the effect of the exhibition and the event. In this case, it is common to manufacture various types of truss structures by fixing fastenings through connecting members or clamps using posts and trusses made of materials such as stainless steel or aluminum.

조립식 트러스 구조물은 설치 및 해체가 비교적 용이하고, 무게에 비해 견고하여, 붕괴느이 위험이 비교적 낮고, 구조 및 크기를 다양하게 제작할 수 있으며, 재활용이 가능하기 때문에 그 수요가 점차 증가하고 있는추세이다. The prefabricated truss structure is relatively easy to install and dismantle, and is robust to weight, so the risk of collapse is relatively low, the structure and size can be manufactured in various ways, and the demand for it is gradually increasing because it is recyclable.

트러스는 BC 2500년경 청동기시대 초기의 호상가옥에 처음으로 사용되었던 것으로 보인다. 초기의 트러스는 나무로 만들어졌다. The truss appears to have been used for the first time in lake houses in the early Bronze Age, around 2500 BC. Early trusses were made of wood.

그리스인은 지붕을 만들 때 트러스를 널리 사용했고, 중세에 와서 그 사용범위가 넓어졌다.The Greeks used truss widely to build the roof, and in the Middle Ages the scope of its use was widened.

19세기초 미국에서 지붕 있는 다리를 개발하면서 트러스에 대한 설계면에서 큰 발전이 있었으며, 트러스 철교의 재료로 주철과 연철 대신 강철을 사용하게 되었다. In the early 19th century, the development of a roofed bridge in the United States made great strides in the design of trusses, and instead of cast iron and wrought iron, steel was used as the material for the truss bridge.

가장 널리 사용되는 트러스 구조에는 프랫(Pratt)식과 워런(Warren)식이 있는데, 사재는 프렛식 트러스에서 서로 평행하고 워런식 트러스에서는 서로 엇갈린다. 트러스는 기중기·승강기 등의 여러 기계와 비행기의 날개·동체에 사용된다. The most widely used truss structures are the Pratt and Warren styles, where the yarns are parallel to each other in the fret truss and staggered in the warren truss. Trusses are used in various machines such as cranes and elevators, and in the wings and fuselage of airplanes.

이러한, 트러스는 큰 외부하중을 지지하는 긴 경간을 가진 구조물의 부재로서 적당하다.This truss is suitable as a member of a structure with a long span supporting a large external load.

이러한, 트러스 구조물은 규격화된 트러스 부재들이 상호 교차 배치하거나 나란하게 위치시켜 하나의 구조물을 완성하는 것으로서, As such, the truss structure is a standardized truss members that cross each other or place them side by side to complete one structure,

트러스 구조물의 기본구조는 수직하중을 지지하고 그하중을 하부구조로 전달하는 역할을 하는 주트러스와, 양측의 주트러스를 연결하여 횡하중에 저항하는 역할을 하는 수평브레이싱과, 횡형과 종형으로 구성되며 바닥판으로부터 전달되는 하중을 주트러스의 격점으로 전달하는 역할을 하는 바닥틀로 구성된다.The basic structure of the truss structure consists of a main truss, which serves to support the vertical load and transmits it to the substructure, and a horizontal bracing, which acts to resist the lateral load by connecting the main trusses on both sides, and a horizontal and vertical type. It is composed of a floor frame that serves to transfer the load transmitted from the floor plate to the break point of the main truss.

첨무도면 도 2 는 본 발명의 일구성인 스피커음 손실방지부재의 일예를 도시한 것으로, 보다 구체적으로 상기 스피커음 손실방지부재(120)는 금속재로 되며, 상기 금속재(140)의 일면에 일정크기의 입자크기를 가지는 연옥분말(141)을 일부분이 표면의 외측으로 노출되도록 침입시켜 코팅되고, 상기 연옥분말(141)의 일부 이탈방지를 위하여 uv수지를 코팅처리하여 도막층(142)을 형성하여 연옥분말 코팅층을 형성하여 구성된다. Fig. 2 shows an example of a speaker sound loss preventing member, which is one component of the present invention, and more specifically, the speaker sound loss preventing member 120 is made of a metal material, and has a certain size on one surface of the metal material 140. The coating is made by intruding the purgatory powder 141 having a particle size so as to be partially exposed to the outside of the surface, and coating the uv resin to prevent the separation of the purgatory powder 141 to form a coating layer 142. It is configured by forming a purgatory powder coating layer.

바람직하게 상기 연옥분말은 1~20㎛의 크기의 미립자상의 연옥분말을 사용하여 침투시키는 것이다. Preferably, the purgatory powder is to be infiltrated using fine-grained purgatory powder having a size of 1 to 20 μm.

본 발명에 따르면, 상기 연옥분말 코팅층은 (1) 미립자상의 연옥분말을 분사물로 하고, 이를 금속재 표면에 대하여 45~130i의 분사각도(θ) 범위 내에서 금속재 표면온도 30~200℃의 온도분위기에서 8~10kgf/㎠의 분사압력으로 강력하게 분사(blasting)하여 1~20㎛의 깊이로 연옥분말이 표면에 노출되게 침입시켜 금속재 표면에 연옥분말을 코팅하는 제1공정과;According to the present invention, the coating layer of the purgatory powder (1) a particulate purgatory powder as a spray, and the metal surface temperature of 30 to 200°C within a spray angle (θ) range of 45 to 130 i with respect to the surface of the metal material A first process of coating the purgatory powder on the surface of the metal by intruding the purgatory powder to the surface with a depth of 1 to 20 µm by strongly blasting with an injection pressure of 8 to 10 kgf/cm 2 in an atmosphere;

(2) 상기 제1공정에서 얻어진 금속재 표면에 코팅된 연옥분말의 탈락을 방지하기 위하여 상기 연옥분말코팅층의 상층으로 도막층을 형성하는 제2공정에 의해 형성되어질 수 있다. (2) In order to prevent dropping of the purgatory powder coated on the surface of the metal material obtained in the first step, it may be formed by a second step of forming a coating layer as an upper layer of the purgatory powder coating layer.

보다 구체적으로 첨부도면 도 3을 참조하여 설명하면, 도 3은 본 발명의 일실시예에 따른 연옥분말 코팅층을 형성하는 일공정을 도시한 것으로, 금속재(150)를 준비하고, 상기 금속재(150)의 일표면을 탈지처리하고 수세하여 세정하여 준비한다. 이때, 상기 금속재(150)은 연옥분말의 경도(6.5~7)보다 낮은 경도를 가지는 마그네슘, 알루미늄, 티타늄 소재중 어느 하나의 금속재를 선택함이 바람직하다. More specifically, with reference to FIG. 3 of the accompanying drawings, FIG. 3 shows a process of forming a purgatory powder coating layer according to an embodiment of the present invention, preparing a metal material 150, and the metal material 150 Prepare by degreasing and washing with water on one surface. At this time, the metal material 150 is preferably selected from any one of the magnesium, aluminum, titanium material having a hardness lower than the hardness (6.5 ~ 7) of the purgatory powder.

상기 금속재의 일표면에 통상의 금속재의 샌딩이나 부식처리용 샌드블라스터(sandblaster)(160)를 사용하여 상기 제1공정을 수행한다. The first process is performed using a sandblaster 160 for sanding or corrosion treatment of a conventional metal material on one surface of the metal material.

상기 샌드블라스터(160)의 분사물로 연옥분말(162)을 사용한다. 상기 연옥분말(162)은 1~20㎛의 입경을 가지며, 상기 연옥분말(162)을 샌드블라스터(160)를 사용하여 금속재(150)위 표면에 대하여 45~130i의 분사각도(θ)의 범위 내에서 금속재(150)위 표면온도 30~200℃의 온도분위기에서 8~10kgf/㎠의 분사압력으로 강력하게 분사(blasting)하여 1~20㎛의 깊이로 연옥분말이 표면에 노출되게 침입시켜 금속재 표면에 연옥분말을 코팅한다. The nephrite powder 162 is used as a spray of the sandblaster 160. The purgatory powder 162 has a particle diameter of 1 to 20㎛, and the purgatory powder 162 of the spray angle (θ) of 45 to 130 i with respect to the surface of the metal material 150 using a sandblaster 160 Within the range, the metal material 150 is strongly blasted with a spraying pressure of 8 to 10 kgf/cm 2 in a temperature atmosphere of 30 to 200°C, to infiltrate the nephrite powder exposed to the surface with a depth of 1 to 20 μm. Purgatory powder is coated on the metal surface.

이때, 상기 금속재 표면온도는 30℃미만일 경우에는 금속재이ㅡ 표면의 강도가 강해 분사압에 대항하는 반발력이 강해 필요이상의 샌드블라스터의 분사압력이 요구되는 문제가 있고, 200℃를 초과하는 분위기에서 작업하면 금속재의 표면이 너무 활성화 되어 연옥분말 대부분이 깊숙하게 금속재 내부로 침투하여 표면 노출율이 저조한 결과를 초래하게 되는 단점이 있다. 따라서, 금속재의 표면처리온도는 30~200℃의 온도범위가 바람직하고, 샌드블라스터의 분사압력은 상기 표면온도의 고저에 따라 차이가 있으나, 바람직하게 8~10kgf/㎠의 분사압력으로 분사하는 것이다. At this time, if the surface temperature of the metal material is less than 30℃, there is a problem that the metal material has a strong surface strength and a strong reaction force against the injection pressure, so that the sandblasting pressure is required more than necessary, and when working in an atmosphere exceeding 200℃ There is a disadvantage in that the surface of the metal material is so active that most of the purgatory powder penetrates deep into the metal material, resulting in poor surface exposure. Therefore, the surface treatment temperature of the metal material is preferably in the temperature range of 30 to 200°C, and the injection pressure of the sandblaster varies depending on the height of the surface temperature, but is preferably injected at an injection pressure of 8 to 10 kgf/cm2. .

이때, 상기 연옥분말 코팅층은 바람직하게 금속재의 전면에 침투되는 것이 좋으며, 이때 외부로 돌출되는 연옥분말의 비율은 바람직하게 금속재 전체 면적의 80%이상의 분사면적을 형성하는 것이 좋다. 80% 이하가 될 경우에는 외부로 스피커음이 흘러나가는 비율이 높아져 바람직하지 않다. At this time, it is preferable that the coating layer of the purgatory powder preferably penetrates the front surface of the metal material, and at this time, the proportion of the purgatory powder protruding to the outside is preferably to form an injection area of 80% or more of the total area of the metal material. When it is 80% or less, the ratio of the speaker sound flowing out is high, which is not preferable.

상기 연옥분말을 침투시킨 다음 스프레이건(170)으로 수 미크론상태의 uv수지도막층(172)을 살포하여 도막을 형성한다. 상기 uv수지도막층을 도포한 다음, uv램프건조장치(180)를 통과시켜 건조하여 요철면(152)상으로 부식된 금속재 표면에 연옥분말과 uv수지도막층이 순차적으로 형성시켜 완성하게 되는 것이다. After infiltrating the purgatory powder, a coating film is formed by spraying a uv resin film layer 172 in a micron state with a spray gun 170. After applying the uv resin film layer, the uv lamp drying device 180 is passed through and dried to form a nephrite powder and a uv resin film layer sequentially on the surface of the corroded metal material to be completed. .

본 발명에 따르면, 상기 도막층은 uv수지를 사용하여 스프레이코팅, 진공증착, 스퍼터링, 플라즈마, 이온코팅중 어느 하나의 방법을 적용하여 형성한다 According to the present invention, the coating layer is formed by applying any one of spray coating, vacuum deposition, sputtering, plasma, and ion coating using uv resin.

본 발명에 따르면, 상기 uv수지도막층을 형성하는데 스프레이건을 사용한 도포에 의한 도막층 형성외에, 진공증착, 스퍼터링, 플라즈마, 이온코팅중 어느 하나의 방법을 적용하여 형성할 수 도 있다. 이떤 방법을 사용하여 도막층을 형성하는 것은 통상의 기술자가 적의 선택하여 적용할 수 있는 것이다.According to the present invention, in addition to forming a coating layer by applying a spray gun to form the uv resin layer, it can also be formed by applying any one of vacuum deposition, sputtering, plasma, and ion coating. Formation of a coating layer using any method can be applied by an ordinary person skilled in the art.
