Description
본 고안은 샌드위치 패널에 관한 것으로서, 보다 상세하게는 장기간 사용하더라도 연결부위가 벌어지는 등의 강도가 약해지는 것을 방지할 수 있고, 시공시 작업자에게 끼치는 해로움 등을 효율적으로 방지할 수 있도록 된 샌드위치 패널에 관한 것이다.The present invention relates to a sandwich panel, and more particularly, to a sandwich panel which can prevent the strength of the connection part from being weakened, even if it is used for a long time, and effectively prevent the harm to the worker during construction. It is about.
일반적으로, 샌드위치 패널은 글래스울이나 스티로폼 또는 우레탄와 같은 충전재의 전후면에 전면판과 배면판을 부착하여 이루어진 것으로, 통상 다수개를 연속적으로 연결하여 건물의 벽체나 지붕 등의 구조를 이루도록 되어 있다. 이때, 상기 글래스울은 단열, 보온 등에 유리하고 특히 불연성이라 샌드위치패널용 충전재로 많이 이용된다.In general, a sandwich panel is formed by attaching a front plate and a back plate to the front and rear surfaces of a filler such as glass wool, styrofoam, or urethane, and are generally configured to connect a plurality of consecutively to form a wall or a roof of a building. In this case, the glass wool is advantageous for heat insulation, thermal insulation, and the like, and is particularly incombustible, and thus is used as a filler for sandwich panels.
도 1은 이러한 글래스울을 이용한 샌드위치패널의 일 실시예를 도시한 것이다. 이를 참조하면, 상기 샌드위치패널은 글래스울(10)의 양면에 전면판(15)과 배면판(20)을 부착하여 이루어진 것으로서, 그 일측단부에는 내측으로 오목한 제1측면연결부(30)와 외측으로 볼록한 제2측면연결부(25)가 각각 마련되어, 다수개를 연속적으로 연결 조립할 때, 상기 측면연결부(25, 30)가 서로 맞물리도록 되어 있다. 또한, 상기 제2측면연결부(25)에는, 도 2에 도시된 바와 같이, 지면에 수직 설치된 지지빔(4) 등에 볼트결합(3)되도록 상하 방향으로 소정 간격의 볼트체결공(27)이형성되어 있다. 이때, 상기 글래스울(10)은 측면연결부(25, 30)와 대응되는 형상으로 절단하기 곤란하기 때문에, 통상 그 양측단과 상하단을 직선으로 절단하게 된다. 이에 따라, 상기 글래스울(10)의 양측단과 측면연결부(25, 30) 사이에는 소정의 공간부가 형성되며, 이 공간부에는 통상 우레탄(36)을 채워 넣어 발포시키게 된다. 그리고, 상기 전면판(15)과 배면판(20)의 단부는 통상 서로 떨어져 있는 관계로, 상기 전면판(15)과 배면판(20)의 단부 사이에는 소정 간격의 이격부(17)가 형성되어, 상기 충전재(10)의 양측단이 이격부(17)를 통해 외부로 노출된다.1 illustrates an embodiment of a sandwich panel using such glass wool. Referring to this, the sandwich panel is made by attaching the front plate 15 and the back plate 20 on both sides of the glass wool 10, the one side end of the first side connection portion 30 concave inward to the outside The convex second side connecting portions 25 are provided, respectively, so that the side connecting portions 25 and 30 are engaged with each other when a plurality of continuous connecting portions are assembled. In addition, as shown in FIG. 2, bolt coupling holes 27 having a predetermined interval are formed in the second side connection part 25 in a vertical direction so as to be bolted to the support beam 4 installed on the ground or the like 3. have. At this time, since the glass wool 10 is difficult to cut into a shape corresponding to the side connecting portions 25 and 30, the glass wool 10 is usually cut in a straight line at both ends and the upper and lower ends. Accordingly, a predetermined space portion is formed between both side ends of the glass wool 10 and the side connecting portions 25 and 30, and the space portion is filled with urethane 36 and foamed. In addition, since the ends of the front plate 15 and the back plate 20 are usually separated from each other, a spaced portion 17 having a predetermined interval is formed between the front plate 15 and the end of the back plate 20. As a result, both ends of the filler 10 are exposed to the outside through the spacer 17.
따라서, 상기 제2측면연결부(25)의 볼트체결공(27)을 통해 샌드위치패널을 지지빔(4) 등에 고정하면서 다른 샌드위치패널들을 좌우 상하 방향으로 연속적으로 연결함으로써, 창고나 가건물 등의 벽체나 지붕과 같은 구조물을 제공할 수 있다.Accordingly, while the sandwich panel is fixed to the support beam 4 through the bolt fastening hole 27 of the second side connection portion 25 and the other sandwich panels are continuously connected to the left and right in the up and down direction, a wall such as a warehouse or a temporary building, It is possible to provide a structure such as a roof.
그런데, 상기 샌드위치패널은 그 전면판(15)과 배면판(20)의 단부가 서로 떨어져 이격부(17)가 발생되어 있고, 상기 우레탄(36)은 열경화되지 않고 공간부에 채워져 발포되어 강도가 약하기 때문에, 이러한 상태에서 장기간 사용하다 보면, 상기 샌드위치패널의 절곡요부(30)가 벌어지면서 서로 연결된 샌드위치패널이 헐거워지거나, 심할 경우 샌드위치패널이 분리되는 문제점이 있다. 또한, 상기 샌드위치패널은 그 양측단부의 이격부(17)를 통해 상기 글래스울(10) 조각이 누출되므로, 작업이 불편함은 물론, 누출된 글래스울(10) 조각이 작업자의 피부를 파고 들어가 건강을 해치게 되는 등의 폐단이 있다.By the way, the sandwich panel is the end portion of the front plate 15 and the back plate 20 is spaced apart from each other to generate a spaced portion 17, the urethane 36 is filled in the space portion without thermal curing and foamed strength Because of the weak, long-term use in such a state, there is a problem that the sandwich panel is loosened when the bending recesses 30 of the sandwich panel is loosened, or the sandwich panel is separated if severe. In addition, since the sandwich panel leaks the glass wool 10 pieces through the spaced portions 17 of both side ends thereof, the work is inconvenient, and the leaked glass wool 10 pieces are dug into the worker's skin. There is a disability, such as being harmful to health.
본 고안은 전술한 바와 같은 문제점에 착안하여 제안된 것으로서, 본 고안의 목적은 장기간 사용하더라도 연결부위가 벌어지는 등의 강도가 약해지는 것을 방지할 수 있고, 시공시 작업자에게 끼치는 해로움 등을 효율적으로 방지할 수 있도록 된 샌드위치 패널을 제공하고자 하는 것이다.The present invention has been proposed in view of the problems described above, the purpose of the present invention can prevent the strength of the connection, such as the connection is weakened even when used for a long time, and effectively prevent the harm to workers during construction We want to provide a sandwich panel that we can do.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.
도 3은 본 고안에 의한 샌드위치패널의 사시도를 도시한 것이고, 도 4는 도 3의 주요부의 평면도를 도시한 것이다. 이를 참조하면, 상기 샌드위치패널은 글래스울로 이루어진 충전재(10)의 양면에 전면판(15)과 배면판(20)이 부착되고, 그 양측단에는 각각 측면연결부(25, 30)가 형성되어, 다수개를 연결하여 조립할 때, 상기 측면연결부(25, 30)가 서로 맞물리도록 구성된 것은 종래와 동일하다.Figure 3 shows a perspective view of the sandwich panel according to the present invention, Figure 4 shows a plan view of the main part of FIG. Referring to this, the sandwich panel is attached to the front plate 15 and the back plate 20 on both sides of the filler 10 made of glass wool, and side connection portions 25 and 30 are formed at both ends thereof, respectively. When connecting and assembling a plurality, the side connection portion 25, 30 is configured to engage with each other is the same as in the prior art.
이때, 도 3 및 도 4에 도시된 바와 같이, 상기 측면연결부(25, 30) 중에서 어느 하나의 측면연결부(30)를 형성하는 배면판(20)과 전면판(15)의 측단부에는 각각 내측을 향하여 산(山) 형상으로 오목하게 절곡된 제1절곡요부(45)와 제2절곡요부(48)가 구비된다. 이러한 제1절곡요부(45)와 제2절곡요부(48)는 서로 부분적으로 중첩되어 맞물려 있다. 또한, 상기 측면연결부(30)에 인접되도록 설치되는 다른 측면연결부(25)를 형성하는 배면판(20)과 전면판(15)의 측단부에는 각각 외측을 향하여 산(山) 형상으로 볼록하게 절곡된 제1절곡돌부(35)와 제2절곡돌부(38)가 구비된다. 이러한 제1절곡돌부(35)와 제2절곡돌부(38)는 서로 부분적으로 중첩되어 맞물려 있다. 결국, 상기 샌드위치패널의 전면판(15)과 배면판(20)의 양측단부는 각각 산(山) 형상으로 절곡 성형된 절곡요부(35. 38)와 절곡돌부(45, 48)에 의해 서로 중첩되도록 맞물려 있기 때문에, 상기 충전재(10)의 측단부에 형성된 공간부(33)에 별도의 우레탄을 채워 넣지 않더라도, 그 강도가 충분히 보강된다.At this time, as shown in Figures 3 and 4, the inner side of the rear end plate 20 and the front end of the front plate 15 to form any one side connection portion 30 of the side connection portions (25, 30), respectively The first bent recess 45 and the second bent recess 48 are provided to be concavely bent in a mountain shape. The first bent recess 45 and the second bent recess 48 are partially overlapped with and engaged with each other. In addition, the rear end portion 20 of the rear plate 20 and the front plate 15 forming the other side connection portion 25 which is installed to be adjacent to the side connection portion 30 are bent convexly in a mountain shape toward the outside. The first bent protrusion 35 and the second bent protrusion 38 are provided. The first bent protrusion 35 and the second bent protrusion 38 partially overlap each other and are engaged with each other. As a result, both side ends of the front plate 15 and the back plate 20 of the sandwich panel overlap each other by the bending recesses 35.38 and the bending protrusions 45 and 48, each of which is bent and formed into a mountain shape. Since it is meshed as much as possible, even if urethane is not filled in the space part 33 formed in the side end part of the said filler material 10, the strength is fully reinforced.
이에 따라, 상기 측면연결부(25, 30)가 서로 맞물려 있는 절곡돌부(35, 38)와 절곡요부(45, 48)에 의해 개방되지 않고 막혀 있으므로, 지면에 설치된 상기 지지빔(4)에 볼트(3) 체결할 때, 도 4에 도시된 A 방향(상기 전면판(15)과배면판(20)이 서로 밀리는 방향)으로 힘이 작용하더라도, 상기 전면판(15)과 배면판(20)이 찌그러지지 않게 된다. 또한, 상기 측면연결부(25, 30)의 배면판(20)과 전면판(15)의 단부는 각각 산(山) 형상으로 절곡된 절곡요부(45, 48)와 절곡돌부(35, 38)에 의해 서로 중첩되어 맞물려 있기 때문에, 도 4에 도시된 B방향(상기 전면판(15)과 배면판(20)이 서로 벌어지려는 방향)으로 힘이 작용하더라도, 상기 전면판(15)과 배면판(20)이 서로 벌어지지 않게 된다.Accordingly, since the side connecting portions 25 and 30 are blocked by the bent protrusions 35 and 38 and the bent recesses 45 and 48 which are engaged with each other, the bolts are attached to the support beam 4 installed on the ground. 3) When fastening, even if a force acts in the A direction (direction in which the front plate 15 and the back plate 20 are pushed together) shown in Figure 4, the front plate 15 and the back plate 20 is It will not be crushed. In addition, end portions of the rear plate 20 and the front plate 15 of the side connecting portions 25 and 30 are respectively formed in the bent recesses 45 and 48 and the bending protrusions 35 and 38 that are bent in a mountain shape. Because of overlapping and interlocking with each other, even if a force acts in the B direction shown in FIG. 4 (the direction in which the front plate 15 and the back plate 20 are to be opened), the front plate 15 and the back plate (20) does not open each other.
결국, 상기 샌드위치패널의 측면연결부(25, 30)는 전면판(15)과 배면판(20)의 양측단부에 각각 구비된 절곡요부(45, 48)와 절곡돌부(35, 38)에 의해 서로 맞물림 결합됨과 동시에 서로 부분적으로 중첩된 상태로 맞닿아 지지되므로, 상기 충전재(10)의 측단부에 형성된 공간부(33)에 별도의 우레탄을 채워 넣지 않더라도, 충분한 강도를 유지할 수 있다. 상기 절곡요부(45, 48)와 절곡돌부(35, 38)는 상기 전면판(15)과 배면판(20)의 양측 단부를 산(山) 형상으로 절곡시켜서 형성하면 된다. 이와 같이, 상기 절곡요부(45, 48)와 절곡돌부(35, 38)가 산(山) 형상으로 절곡 성형되어 있기 때문에, 서로 연결된 샌드위치패널이 전후 좌우 방향으로의 외력이 작용하더라도, 상기 절곡요부(45, 48)와 절곡돌부(35, 38)가 서로 인접되는 방향으로 복귀 및 수렴된다. 이에 따라, 서로 인접 연결된 샌드위치패널의 위치 변동이 발생되는 경우를 효율적으로 방지할 수 있다.As a result, the side connection portions 25 and 30 of the sandwich panel are mutually formed by the bending recesses 45 and 48 and the bending protrusions 35 and 38 respectively provided at both end portions of the front plate 15 and the rear plate 20. Since it is engaged with each other and partially overlapped with each other while being engaged with each other, sufficient strength can be maintained even if a separate urethane is not filled in the space 33 formed at the side end of the filler 10. The bending recesses 45 and 48 and the bending protrusions 35 and 38 may be formed by bending both end portions of the front plate 15 and the back plate 20 in a mountain shape. As described above, since the bending recesses 45 and 48 and the bending protrusions 35 and 38 are bent and formed into a hill shape, even when the sandwich panels connected to each other exert an external force in the front and rear directions, the bending recesses The 45 and 48 and the bent portions 35 and 38 are returned and converged in directions adjacent to each other. Accordingly, it is possible to effectively prevent the case where the positional variation of the sandwich panels connected adjacent to each other occurs.
따라서, 상기 샌드위치패널은 충전재(10)의 측단부와 전후면판(15, 20) 사이의 공간부(33)에 별도의 우레탄을 채워 넣지 않아도 충분한 강도가 유지되어 있기 때문에, 조립후에 외부의 충격이 가해지더라도 상기 전면판(15)과 배면판(20)의 양측단부가 벌어지거나 찌그러지는 것을 방지할 수 있으므로, 서로 연결된 샌드위치패널이 연결부위가 헐거워지거나 분리될 염려가 없다. 또한, 상기 절곡요부(45, 48)와 절곡돌부(35, 38)는 상기 전면판(15)과 배면판(20)의 양측 단부를 산(山) 형상으로 절곡시켜서 형성하면 되므로, 그 작업 공정이 매우 신속하면서도 간편할 뿐만 아니라, 그 강도도 충분히 보강되는 장점이 있다. 그리고, 상기 샌드위치패널은 이처럼 충전재(10) 양측단과 전후면판(15, 20) 사이의 공간부(33)에 완전한 불연성이 아닌 우레탄을 별도로 채워 넣지 않아도 되므로, 화재의 위험이 없다. 그리고, 상기 샌드위치패널은 시공 도중 그 양측단으로 충전재(10)인 글래스울 조각이 누출되는 경우가 없기 때문에, 종래와 같이 글래스울 조각이 작업자의 피부를 파고 들어가 건강을 해치게 되는 등의 폐단을 방지할 수 있다.Accordingly, since the sandwich panel has sufficient strength to be maintained even if the urethane portion is not filled in the space portion 33 between the side end portion of the filler 10 and the front and rear plates 15 and 20, external impact may not occur after assembling. Even if applied, since both ends of the front plate 15 and the back plate 20 can be prevented from being crushed or crushed, the sandwich panels connected to each other are not loosened or separated from each other. In addition, the bending recesses 45 and 48 and the bending protrusions 35 and 38 may be formed by bending both end portions of the front plate 15 and the back plate 20 in a mountain shape, and thus, the work process This is not only very quick and simple, but also has the strength that the strength is sufficiently reinforced. In addition, the sandwich panel does not need to separately fill a urethane which is not completely incombustible in the space 33 between the both ends of the filler 10 and the front and rear plates 15 and 20, so there is no danger of fire. In addition, since the sandwich panel does not leak the glass wool fragments, which are the filler 10, to both sides thereof during construction, the glass wool fragments penetrate the skin of the worker and prevent the closure such as damage to health. can do.
한편, 상기 전면판(15)에는, 도 3에 도시된 바와 같이, 가로 방향을 따라 수직 방향의 소골부(52a)가 일정 간격으로 형성되어 있고, 상기 소골부(52a) 사이에는 소골부(52a)보다 상대적으로 폭이 넓은 다수개의 대골부(52b)가 형성되어 있다. 이와 같이, 상기 소골부(52a)가 가로 방향을 따라 일정 간격으로 형성되어 있기 때문에, 미관을 효과적으로 살릴 수 있음은 물론, 상기 소골부(52a) 사이에는 다수개의 대골부(52b)가 형성되어 있기 때문에, 다수개의 샌드위치패널을 상호 연결하였을 때, 상기 샌드위치패널의 연결부위가 외관상 눈에 띄지 않게 되므로, 외관의 손상을 방지할 수 있다.On the other hand, the front plate 15, as shown in Figure 3, the rib portion 52a in the vertical direction along the horizontal direction is formed at regular intervals, between the rib portion 52a between the rib portion 52a A plurality of wide bones (52b) is relatively wider than the) is formed. As described above, since the osseous part 52a is formed at a predetermined interval along the horizontal direction, the aesthetic appearance can be effectively saved, and a plurality of sciatic parts 52b are formed between the osseous parts 52a. Therefore, when a plurality of sandwich panels are connected to each other, the connection portion of the sandwich panel is not visible in appearance, it is possible to prevent damage to the appearance.
이상에서와 같이 본 고안에 의하면, 상기 샌드위치패널은 충전재와 전후면판 사이의 공간부에 수분 침투 등을 방지하기 위한 난연성 우레탄을 채워 넣지 않아도 그 강도가 충분히 보강되므로, 제조 공정이 매우 신속하면서도 간편하며, 외부의 충격이 가해지더라도 연결부위가 벌어지는 경우가 없어 보다 견고한 구조를 이루면서도 화재의 위험이 없고, 시공시 양측단으로 글래스울 조각이 누출되면서 작업자의 피부를 파고 들어가 건강을 해치게 되는 폐단을 방지할 수 있는 장점이 있다.As described above, according to the present invention, the sandwich panel is reinforced with sufficient strength even without filling a flame-retardant urethane for preventing moisture infiltration into the space between the filler and the front and rear plates, so that the manufacturing process is very quick and simple. Even if an external impact is applied, the connection part does not open, thus creating a more rigid structure, and there is no risk of fire.As a piece of glass wool leaks to both sides during construction, it prevents the lung from being damaged by digging into the worker's skin. There is an advantage to this.
