Description

열가소성 폴리올레핀 시트를 구비하는 데크패널Deck Panel with Thermoplastic Polyolefin Sheet
본 발명은 TPO시트와 강판 사이에 발포체가 채워지도록 구성되는 데크패널에 관한 것으로, 더 상세하게는 TPO시트가 부착된 면의 평편도가 향상될 수 있고 연이어 연결되는 데크패널 사이의 밀폐성이 향상되도록 구성되는 데크패널에 관한 것이다.The present invention relates to a deck panel configured to fill a foam between a TPO sheet and a steel sheet, and more particularly, to improve the flatness of the surface to which the TPO sheet is attached and to improve the sealing property between the deck panels connected in series. It is related with the deck panel comprised.
지붕에 사용되는 데크패널의 경우 강판과 우레탄을 기본 구성요소로 제작된다. 강판은 데크패널의 구조적 골격을 이루는 부분이며, 우레탄은 강판 내부에 충진되어 단열 기능을 수행하게 된다. Deck panels used for roofing are made of steel and urethane as basic components. Steel sheet is a part of the structural skeleton of the deck panel, urethane is filled in the steel sheet to perform a heat insulating function.
이때, 상기와 같이 강판과 우레탄으로만 구성되는 데크패널은 방수성이 불량하므로, 방수성 향상을 위해 우레탄의 일면에 열가소성 폴리올레핀 시트((Thermoplastic polyolefin sheet : 이하 'TPO시트'라 약칭함)가 추가로 부착되는 데크패널이 본 발명의 출원인에 의해 제안된 바 있다. 상기 TPO시트는 기본적으로 방수 기능을 갖되, 인장강도와 내열강도의 물성값을 높이는 복합재가 포함되어 있는바, 데크패널의 강성을 향상시키는 기능도 수행하게 된다.At this time, the deck panel consisting of a steel sheet and urethane as described above is poor in water resistance, so that a thermoplastic polyolefin sheet (hereinafter referred to as 'TPO sheet') is additionally attached to one side of the urethane to improve the water resistance. The deck panel has been proposed by the applicant of the present invention The TPO sheet is basically a waterproof function, but includes a composite material to increase the properties of the tensile strength and the heat resistance strength bar to improve the rigidity of the deck panel Will also be performed.
이하 첨부된 도면을 참조하여 종래의 데크패널에 대해 상세히 설명한다.Hereinafter, a conventional deck panel will be described in detail with reference to the accompanying drawings.
도 1은 종래의 데크패널 단면도이고, 도 2는 종래의 데크패널 제2 실시예의 단면도이며, 도 3은 종래의 데크패널이 연결되는 구조를 도시하는 단면도이다.1 is a cross-sectional view of a conventional deck panel, FIG. 2 is a cross-sectional view of a second embodiment of a conventional deck panel, and FIG. 3 is a cross-sectional view illustrating a structure in which a conventional deck panel is connected.
종래의 데크패널(10)은 요철 형상을 갖는 강판(12)과, 상기 강판(12)과 평행하게 이격되는 TPO시트(14)와, 강판(12)과 TPO시트(14) 사이를 채우는 발포체(16)를 포함하여 구성된다. 상기 강판(12)은 압축강도 및 인장강도, 비틀림강도 등이 우수한 금속으로 제작되며, 발포체(16)는 우레탄 등과 같이 단열성이 높은 재료로 이루어진다. Conventional deck panel 10 is a steel sheet 12 having a concave-convex shape, a TPO sheet 14 spaced apart in parallel to the steel sheet 12, and a foam filling the steel sheet 12 and the TPO sheet 14 ( 16). The steel sheet 12 is made of a metal having excellent compressive strength, tensile strength, torsional strength, and the like, and the foam 16 is made of a material having high thermal insulation such as urethane.
이와 같이 구성되는 종래의 데크패널(10)은 강도가 높으면서도 단열성이 우수할 뿐만 아니라, 발포체(16)의 일면에 TPO시트(14)가 마련되는바 방수성이 매우 우수하므로, 건축자재로의 활용성이 매우 높다는 장점이 있다. Conventional deck panel 10 configured as described above is not only excellent in heat insulation but also high in strength, TPO sheet 14 is provided on one surface of the foam 16 is very excellent in water resistance, it is utilized as a building material The advantage is that the castle is very high.
그러나 이와 같은 종래의 데크패널(10)은, 강판(12)과 TPO시트(14) 사이로 발포체(16)를 주입하는 과정에서 도 1에 도시된 바와 같이 공기층(17)이 발생되어 TPO시트(14)의 표면이 볼록하게 돌출되거나, 도 2에 도시된 바와 같이 발포체(16)가 함몰되어 도 2에 도시된 바와 같이 TPO시트(14)의 표면이 오목하게 인입되는 문제가 발생될 수 있다. However, the conventional deck panel 10, as shown in Figure 1 in the process of injecting the foam 16 between the steel sheet 12 and the TPO sheet 14, the air layer 17 is generated, the TPO sheet 14 2) may protrude convexly, or the foam 16 may be recessed as shown in FIG. 2 and the surface of the TPO sheet 14 may be recessedly drawn as shown in FIG. 2.
또한, 도 3에 도시된 바와 같이 두 개의 데크패널(10a, 10b)을 연결하였을 때 각 데크패널(10a, 10b)의 TPO시트(14a, 14b) 사이가 완벽하게 밀폐되지 못하므로, 두 개의 TPO시트(14a, 14b) 사이의 경계선을 통해 외기가 유입됨으로써 단열성이 현저히 떨어질 수 있고, 두 개의 TPO시트(14a 14b) 사이를 통해 빗물이 유입되어 실내로 빗물이 떨어지는 문제 등이 발생될 수 있다. In addition, when two deck panels 10a and 10b are connected as shown in FIG. 3, the TPO sheets 14a and 14b of each deck panel 10a and 10b are not completely sealed, and thus, two TPOs are connected. As the outside air flows through the boundary line between the sheets 14a and 14b, the heat insulation may be remarkably degraded, and rainwater may flow through the two TPO sheets 14a 14b and rain may fall into the room.
따라서 두 개의 데크패널(10a, 10b)을 연결할 때에는 두 개의 TPO시트(14a, 1b) 사이의 경계선에 별도의 보강시트(20)를 접착시켜 두 개의 TPO시트(14a, 14b) 사이를 밀폐시킴이 바람직한데, 이와 같은 방식으로 두 개의 TPO시트(14a, 14b) 사이를 밀폐시키기 위해서는 별도의 보강시트(20)를 제작하여야하므로 시공비용이 상승되고, 두 개의 TPO시트(14a, 14b) 간의 경계선을 따라 보강시트(20)를 정확히 접착시켜야하므로 작업자의 숙련도에 따라 데크패널(10)의 완성도에 큰 차이가 발생될 수 있다는 문제점이 있다. 또한, 보강시트(20)와 두 개의 TPO시트(14a, 14b) 사이에 두 개의 경계선이 외부로 노출되므로, 미관이 나빠진다는 단점이 있다.Therefore, when connecting the two deck panels (10a, 10b) to seal the gap between the two TPO sheets (14a, 14b) by bonding a separate reinforcing sheet 20 to the boundary between the two TPO sheets (14a, 1b). Preferably, in order to seal between the two TPO sheets 14a and 14b in this manner, a separate reinforcement sheet 20 must be manufactured, thereby increasing the construction cost, and forming a boundary line between the two TPO sheets 14a and 14b. Accordingly, since the reinforcing sheet 20 must be adhered correctly, there is a problem that a large difference may occur in the completeness of the deck panel 10 according to the skill of the operator. In addition, since two boundary lines are exposed to the outside between the reinforcing sheet 20 and the two TPO sheets 14a and 14b, there is a disadvantage that the aesthetics deteriorate.
본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로, 두 개의 데크패널을 연결할 때 두 개의 데크패널 사이가 밀폐될 수 있으며, TPO시트의 평탄도가 기준치 이상으로 높게 확보될 수 있는 데크패널을 제공하는데 목적이 있다.The present invention has been proposed to solve the above problems, when connecting the two deck panel can be sealed between the two deck panel, the deck panel can be secured higher than the standard flatness of the TPO sheet The purpose is to provide.

본 발명에 의한 데크패널(100)은 건축구조물의 벽체나 천정 등으로 사용되는 건축자재의 일종으로서, 일정 수준 이상의 강성을 갖도록 일정 두께를 갖는 금속으로 이루어지되 플레이트 형상으로 제작되는 강판(110)과, 상기 강판(110)과 일정 거리 이격된 상태를 유지하며 상기 강판(110)과 평행하게 설치되는 열가소성 폴리올레핀 시트((Thermoplastic polyolefin sheet : 이하 'TPO시트(120)'라 약칭함)와, 상기 강판(110)과 TPO시트(120) 사이에 채워지는 발포체(130)를 포함하여 구성된다. 상기 강판(110)과 TPO시트(120)와 발포체(130)는 도 1 내지 도 3에 도시된 종래의 데크패널(10)에도 실질적으로 동일하게 적용되어 있는바, 이들의 재료나 결합방법에 대한 상세한 설명은 생략한다. Deck panel 100 according to the present invention is a kind of building material used as a wall or ceiling of a building structure, made of a metal having a certain thickness to have a certain level of rigidity, but the steel plate 110 is made in a plate shape and The thermoplastic polyolefin sheet (hereinafter, abbreviated as 'TPO sheet 120') installed in parallel with the steel sheet 110 while maintaining a state spaced apart from the steel sheet 110 and the steel sheet It comprises a foam 130 that is filled between the 110 and the TPO sheet 120. The steel sheet 110, TPO sheet 120 and the foam 130 is shown in Figures 1 to 3 Since the same applies to the deck panel 10, the detailed description about these materials and the bonding method is abbreviate | omitted.
이때, 본 발명에 의한 데크패널(100)은, 두 개의 데크패널(100)이 상호 연결되었을 때 별도의 보강시트(20)(도 3 참조) 없이도 두 개의 데크패널(100) 사이가 밀폐될 수 있도록, 상기 TPO시트(120)의 일측(도 4에서는 좌측)이 발포체(130)의 끝단보다 외측(도 4에서는 좌측)으로 더 연장되는 구조 즉, TPO시트(120)가 일측에 연장부(122)를 구비하는 구조로 제작된다는 점에 구성상의 가장 큰 특징이 있다.At this time, the deck panel 100 according to the present invention, when the two deck panels 100 are interconnected can be sealed between the two deck panels 100 without a separate reinforcing sheet 20 (see Fig. 3). One side (left side in FIG. 4) of the TPO sheet 120 extends further to the outside (left side in FIG. 4) than the end of the foam 130, that is, the TPO sheet 120 extends 122 on one side thereof. The biggest feature of the configuration is that it is manufactured in a structure having a).
이와 같이 TPO시트(120)의 일측에 연장부(122)가 추가로 구비되면, 도 5에 도시된 바와 같이 두 개의 데크패널(100a, 100b)이 연결되었을 때, 우측에 위치하는 데크패널(100b)의 연장부(122b)가 좌측에 위치하는 데크패널(100a)의 TPO시트(120a) 끝단을 덮도록 부착됨으로써, 두 개의 데크패널(100a, 100b) 사이가 별도의 보강시트 없이도 완벽하게 밀폐될 수 있다. 이때, 상기 연장부(122b)는 좌측에 위치하는 데크패널(100a)의 TPO시트(120a)에 적층된 상태에서 가열되었을 때 상기 TPO시트(120a)에 부착되는데, 이와 같은 방식으로 TPO시트(120)를 접착시키는 방법은 이미 본 발명이 해당하는 분야에서 상용화되어 있는 것이므로, 이에 대한 상세한 설명은 생략한다.As such, when the extension part 122 is additionally provided at one side of the TPO sheet 120, when the two deck panels 100a and 100b are connected as shown in FIG. 5, the deck panel 100b located on the right side is provided. The extension portion 122b of the) is attached to cover the end of the TPO sheet 120a of the deck panel 100a on the left side, so that the two deck panels 100a and 100b may be completely sealed without a separate reinforcing sheet. Can be. In this case, the extension part 122b is attached to the TPO sheet 120a when heated in a stacked state on the TPO sheet 120a of the deck panel 100a located on the left side. ) Is already commercialized in the corresponding field, the detailed description thereof will be omitted.
또한, 도 3에 도시된 바와 같이 별도의 보강시트(20)를 이용하는 경우에는, 보강시트(20)를 정확한 위치에 부착시켜야 두 개의 데크패널(100a, 100b) 사이의 간극을 완벽하게 밀폐시킬 수 있으므로 보강시트(20) 부착에 많은 시간이 소요될 뿐만 아니라, 작업자의 숙련도가 낮은 경우 보강시트(20)의 부착위치가 약간 어긋남으로 인해 두 개의 데크패널(100a, 100b) 사이의 간극이 완벽하게 밀폐되지 못하는 경우가 발생된다는 문제점이 있다. 그러나 본 발명에 의한 데크패널(100)에서 두 개의 데크패널(100a, 100b) 사이의 간극을 밀폐시키기 위한 연장부(122)는, TPO시트(120)와 별도로 제작된 후 부착되는 것이 아니라 TPO시트(120)의 일부로 제작되므로 부착위치 선정이 매우 용이하다는 장점이 있다.In addition, when using a separate reinforcing sheet 20, as shown in Figure 3, the reinforcing sheet 20 should be attached at the correct position to completely seal the gap between the two deck panels (100a, 100b). Therefore, it takes a lot of time to attach the reinforcement sheet 20, and if the operator's skill is low, the gap between the two deck panels (100a, 100b) is completely sealed due to the slightly shifted position of the reinforcement sheet 20 There is a problem that can not occur. However, in the deck panel 100 according to the present invention, the extension 122 for sealing the gap between the two deck panels 100a and 100b is not separately attached to the TPO sheet 120 and is not attached to the TPO sheet. Since it is manufactured as a part of 120, there is an advantage that the selection of the mounting position is very easy.
즉, 상기 연장부(122)를 부착시킬 때에는, 상기 연장부(122)를 연장방향(도 5에서는 좌측방향)으로 팽팽하게 잡아당기면서 좌측 TPO시트(120a) 상면에 안착시키는 조작만으로 상기 연장부(122)를 정확한 위치에 안착시킬 수 있다는 장점이 있다. 이와 같이 상기 연장부(122)의 부착위치 선정이 용이해지면, 그만큼 데크패널(100)의 조립시간을 줄임으로써 건축공기를 단축시킬 수 있고, 시트 부착 숙련도가 낮은 작업자라도 상기 연장부(122)를 잘못 부착시킬 우려가 매우 낮아지므로 불량률을 낮출 수 있다는 장점이 있다.That is, when attaching the extension part 122, the extension part is merely mounted on the upper surface of the left TPO sheet 120a while pulling the extension part 122 in the extension direction (left direction in FIG. 5). There is an advantage in that the 122 can be seated in the correct position. As described above, when the attachment position of the extension part 122 is easily selected, the construction air can be shortened by reducing the assembly time of the deck panel 100. There is an advantage that the failure rate can be lowered because the risk of incorrect attachment is very low.
또한, 도 3에 도시된 보강시트(20)는 좌측에 위치하는 TPO시트(14a)와의 접착과 우측에 위치하는 TPO시트(14b)와의 접착 중 어느 한쪽의 접착에 불량이 발생되더라도 두 개의 데크패널(10a, 10b) 사이의 간극이 밀폐되지 못하게 된다는 문제점이 있다. 그러나 본 발명에 포함되는 연장부(122)는 어느 하나의 TPO시트(120)(도 5에서는 우측 TPO시트(120b))와 일체로 제작되므로, 다른 하나의 TPO시트(120)(도 5에서는 좌측 TPO시트(120a))와의 접착만 정상적으로 유지되면 두 개의 데크패널(100a, 100b) 사이의 간극을 안정적으로 밀폐시키는 상태를 유지할 수 있게 된다. 즉, 본 발명에 의한 데크패널(100)은 연장부(122)가 떨어질 우려가 절반으로 감소되므로, 데크패널(100) 간의 조립 내구성이 매우 높아진다는 장점이 있다.In addition, the reinforcement sheet 20 shown in FIG. 3 has two deck panels even if a defect occurs in the adhesion of any one of the adhesion with the TPO sheet 14a positioned on the left side and the adhesion with the TPO sheet 14b positioned on the right side. There is a problem that the gap between 10a and 10b is not sealed. However, since the extension part 122 included in the present invention is manufactured integrally with any one TPO sheet 120 (the right TPO sheet 120b in FIG. 5), the other TPO sheet 120 (the left in FIG. 5). If only adhesion to the TPO sheet 120a) is normally maintained, it is possible to maintain a state of stably sealing the gap between the two deck panels 100a and 100b. That is, the deck panel 100 according to the present invention has the advantage that the extension part 122 may fall in half, so that the durability of the assembly between the deck panels 100 is very high.
한편, 종래와 같이 보강시트(20)를 이용하는 경우에는 보강시트(20)와 TPO시트(120) 간의 경계선이 2개 형성되지만, 본 발명에 의한 데크패널(100)과 같이 연장부(122)를 이용하는 경우에는 연장부(122)와 TPO시트(120) 간의 경계선이 1개만 형성되므로, 외관이 미려해진다는 장점도 얻을 수 있다.On the other hand, when using the reinforcing sheet 20 as in the prior art, but two boundary lines between the reinforcing sheet 20 and the TPO sheet 120 is formed, the extension portion 122 as in the deck panel 100 according to the present invention In the case of using, since only one boundary line between the extension part 122 and the TPO sheet 120 is formed, it is possible to obtain an advantage that the appearance is beautiful.
도 6은 본 발명에 의한 데크패널(100) 제2 실시예의 단면도이다.6 is a cross-sectional view of the second embodiment of the deck panel 100 according to the present invention.
한편, TPO시트(120)는 일반적으로 큰 강도를 가지지 아니하는 유연한 재질을 가지므로, 강판(110)과 TPO시트(120) 사이로 발포체(130)를 주입하는 과정에서 공기층이 발생되는 경우 TPO시트(120)에 볼록하게 돌출되는 부위와 오목하게 함몰되는 부위가 발생되어, 데크패널(100)의 표면 평탄도가 나빠진다는 문제가 발생될 수 있다.On the other hand, since the TPO sheet 120 has a flexible material that generally does not have a large strength, when the air layer is generated in the process of injecting the foam 130 between the steel sheet 110 and the TPO sheet 120 TPO sheet ( The convex protruding portion and the concave portion recessed portion may be generated in the 120, so that the surface flatness of the deck panel 100 may be deteriorated.
본 발명에 의한 데크패널(100)은 상기와 같은 문제점을 해결할 수 있도록, 도 6에 도시된 바와 같이 상기 TPO시트(120)의 내측면 즉, 발포체(130)와 대응되는 면에는 우레탄 코팅층(140)이 형성될 수 있다. 이와 같이 TPO시트(120)의 내측면에 우레탄 코팅층(140)이 형성되면, 상기 우레탄 코팅층(140)이 발포된 후 강판(110)과 TPO시트(120) 사이에 발포체(130)를 주입함으로써, 상기 발포체(130)의 표면에 굴곡이 발생되더라도 상기 우레탄 코팅층(140)이 발포체(130)의 굴곡을 채워 도 6에 도시된 바와 같이 TPO시트(120)의 외측면 평탄도를 높게 유지할 수 있다. Deck panel 100 according to the present invention to solve the above problems, the urethane coating layer 140 on the inner surface of the TPO sheet 120, that is, the surface corresponding to the foam 130 as shown in Figure 6 ) May be formed. When the urethane coating layer 140 is formed on the inner surface of the TPO sheet 120 as described above, by injecting the foam 130 between the steel sheet 110 and the TPO sheet 120 after the urethane coating layer 140 is foamed, Even if bending occurs on the surface of the foam 130, the urethane coating layer 140 may fill the bending of the foam 130 to maintain the flatness of the outer surface of the TPO sheet 120 as shown in FIG. 6.
이때, 상기 우레탄 코팅층(140)의 두께는, TPO시트(120)의 재질 및 두께, 발포체(130)의 종류나 주입압력 등 여러 조건에 따라 다양하게 설정될 수 있으므로, 이에 대한 상세한 설명은 생략한다.In this case, the thickness of the urethane coating layer 140 may be variously set according to various conditions such as the material and thickness of the TPO sheet 120, the type or injection pressure of the foam 130, a detailed description thereof will be omitted. .
도 7은 본 발명에 의한 데크패널(100) 제3 실시예의 단면도이다.7 is a cross-sectional view of the third embodiment of the deck panel 100 according to the present invention.
도 6에 도시된 실시예와 같이 TPO시트(120)에 우레탄 코팅층(140)을 형성한다 하더라도, 발포체(130)의 표면 굴곡이 매우 심한 경우에는 TPO시트(120)의 외측면 평탄도를 높게 유지시키는데 한계가 발생된다. 특히, 발포체(130)의 두께가 두꺼운 경우에는 발포체(130)의 표면 굴국이 커지게 되므로, TPO시트(120)의 외측면 평탄도를 높게 유지하기 어렵게 된다. 즉, 발포체(130)의 두께가 두꺼우면 공기층이 형성되는 문제나 표면에 함몰부가 형성되는 문제가 크게 발생되므로 TPO시트(120)의 평탄도를 높게 유지시키기 어려워진다. 물론, 발포체(130)의 두께를 감소시키면 그만큼 TPO시트(120)의 평탄도를 높게 유지시키기 쉬워지지만, 발포체(130)의 두께를 감소시키면 데크패널(100)의 단열성 및 방음성 등이 현저히 저하되는 문제가 발생되므로 상기 발포체(130)의 두께는 기준범위 이내로 두껍게 유지되어야 한다.Even when the urethane coating layer 140 is formed on the TPO sheet 120 as shown in FIG. 6, when the surface bending of the foam 130 is very severe, the outer surface flatness of the TPO sheet 120 is kept high. There is a limit to this. In particular, when the thickness of the foam 130 is thick, since the surface roughness of the foam 130 becomes large, it is difficult to maintain the outer surface flatness of the TPO sheet 120 high. That is, when the thickness of the foam 130 is thick, it is difficult to maintain the flatness of the TPO sheet 120 because the problem that the air layer is formed or the problem that the depression is formed on the surface is greatly generated. Of course, reducing the thickness of the foam 130 makes it easier to maintain the flatness of the TPO sheet 120 by that much, while reducing the thickness of the foam 130 significantly lowers the thermal insulation and sound insulation of the deck panel 100. Since a problem occurs, the thickness of the foam 130 should be kept thick within the reference range.
따라서 본 발명에 의한 데크패널(100)은 발포체(130)의 전체 두께가 기준범위 이내로 두껍게 유지되면서도 TPO시트(120)의 평탄도가 높게 유지될 수 있도록, 상기 강판(110)과 TPO시트(120) 사이에 삽입되는 평판 형상의 보강판(150)이 추가로 구비될 수 있다. 상기 보강판(150)은 TPO시트(120)와 평행하게 배열되어 강판(110)과 TPO시트(120) 사이의 공간을 두 개로 구분하는 기능을 수행하는바, 보강판(150)과 TPO시트(120) 사이를 채우는 발포체(130)의 두께는 얇아지는 효과를 얻을 수 있다. 즉, 보강판(150)과 TPO시트(120) 사이에 채워지는 발포체(130)의 두께가 얇아지면, 보강판(150)과 TPO시트(120) 사이에 채워지는 발포체(130)에 공기층이 형성되는 경우가 현저히 줄어들게 되고, 상기 발포체(130)의 굴곡 또한 현저히 줄어들게 되므로, TPO시트(120)의 평탄도가 높게 유지되는 효과를 얻을 수 있게 된다.Accordingly, the deck panel 100 according to the present invention may maintain the flatness of the TPO sheet 120 while maintaining the overall thickness of the foam 130 to be thick within the reference range, the steel sheet 110 and the TPO sheet 120 The plate-shaped reinforcement plate 150 may be further provided therebetween. The reinforcement plate 150 is arranged in parallel with the TPO sheet 120 to perform the function of dividing the space between the steel plate 110 and the TPO sheet 120 into two bars, the reinforcement plate 150 and the TPO sheet ( The thickness of the foam 130 filling the gap between 120 may be obtained a thinning effect. That is, when the thickness of the foam 130 filled between the reinforcement plate 150 and the TPO sheet 120 becomes thin, an air layer is formed on the foam 130 filled between the reinforcement plate 150 and the TPO sheet 120. If the case is significantly reduced, the curvature of the foam 130 is also significantly reduced, it is possible to obtain the effect of maintaining the flatness of the TPO sheet 120 is high.
또한, 본 실시예에 도시된 바와 같이 보강판(150)이 추가로 구비되면 TPO시트(120)의 평탄도가 향상될 뿐만 아니라 데크패널(100) 전체의 강도가 크게 증가되므로, 본 발명에 의한 데크패널(100)이 보다 큰 하중을 견딜 수 있게 되고, 이에 따라 보다 무거운 구조물 또는 건축물을 짓는 용도로 활용될 수 있다는 장점도 얻을 수 있다.In addition, when the reinforcing plate 150 is additionally provided as shown in the present embodiment, not only the flatness of the TPO sheet 120 is improved but also the strength of the entire deck panel 100 is greatly increased. Deck panel 100 is able to withstand greater loads, and thus can also be used for the purpose of building heavier structures or buildings.
한편, 본 발명에 의한 데크패널(100)이 강판(110)과 TPO시트(120)와 발포체(130)만으로 구성되는 경우, 상기 강판(110)이 TPO시트(120)에 비해 각종 강도가 우수하므로, 발포체(130) 중 강판(110)이 결합된 측보다 TPO시트(120)가 결합된 측의 강도가 낮아지게 된다. 따라서 강판(110)과 TPO시트(120) 사이에 보강판(150)이 추가로 삽입되는 경우, 상기 보강판(150)은 상기 강판(110)보다 상기 TPO시트(120)와 가까운 지점에 설치됨이 바람직하다. 또한 본 실시예에서는 강판(110)과 TPO시트(120) 사이에 보강판(150)이 하나만 추가되는 경우만을 도시하고 있으나, 강판(110)과 TPO시트(120) 사이에는 보강판(150)이 둘 이상 삽입될 수도 있다. 또한 상기 강판(110)의 재질 및 두께는, 본 발명에 의한 데크패널(100)의 용도나 강판(110)의 강성 등에 따라 다양하게 설정될 수 있다.On the other hand, when the deck panel 100 according to the present invention is composed of only the steel sheet 110 and the TPO sheet 120 and the foam 130, since the steel sheet 110 is superior in various strengths compared to the TPO sheet 120 The strength of the side of the TPO sheet 120 is lower than the side of the foam 130, the steel sheet 110 is coupled. Therefore, when the reinforcing plate 150 is additionally inserted between the steel sheet 110 and the TPO sheet 120, the reinforcing plate 150 is installed at a point closer to the TPO sheet 120 than the steel sheet 110 desirable. In addition, in this embodiment, only the case where only one reinforcing plate 150 is added between the steel sheet 110 and the TPO sheet 120 is shown, the reinforcing plate 150 between the steel plate 110 and the TPO sheet 120 More than one may be inserted. In addition, the material and thickness of the steel sheet 110 may be variously set according to the use of the deck panel 100 according to the present invention or the rigidity of the steel sheet 110.
도 8은 본 발명에 의한 데크패널(100) 제4 실시예의 단면도이다.8 is a cross-sectional view of the fourth embodiment of the deck panel 100 according to the present invention.
본 발명에 의한 데크패널(100)은, 도 7에 도시된 바와 같이 강판(110)과 TPO시트(120) 사이에 삽입되는 보강판(150)이 강판(110)과도 이격되고 TPO시트(120)와도 이격되어 강판(110)과 보강판(150) 사이에도 발포체(130)가 주입되고 보강판(150)과 TPO시트(120) 사이에도 발포체(130)가 주입되도록 구성될 수도 있고, 상기 보강판(150)이 TPO시트(120)에 밀착되도록 즉, 도 8에 도시된 바와 같이 TPO시트(120) 중 발포체(130)와 대응되는 면에 부착되도록 구성될 수 있다. 이때 TPO시트(120)는 외부로부터 인가되는 열에 의해 보강판(150)에 융착될 수 없으므로, 상기 TPO시트(120)와 보강판(150)은 별도의 접착제(160)에 의해 접착되어야 할 것이다. 여기서 접착제(160)는 고무계열 접착제가 이용될 수 있다. Deck panel 100 according to the present invention, as shown in Figure 7, the reinforcing plate 150 is inserted between the steel sheet 110 and the TPO sheet 120 is also spaced apart from the steel sheet 110 and the TPO sheet 120 Also, the foam 130 may be injected between the steel plate 110 and the reinforcement plate 150, and the foam 130 may also be injected between the reinforcement plate 150 and the TPO sheet 120. 150 may be in close contact with the TPO sheet 120, that is, attached to a surface of the TPO sheet 120 corresponding to the foam 130 as shown in FIG. 8. At this time, since the TPO sheet 120 cannot be fused to the reinforcement plate 150 by heat applied from the outside, the TPO sheet 120 and the reinforcement plate 150 should be adhered by a separate adhesive 160. Here, the adhesive 160 may be a rubber-based adhesive.
이와 같이 상기 보강판(150)과 TPO시트(120) 사이에 발포체(130)가 주입되지 아니하고 보강판(150)과 TPO시트(120)에 직접 결합되는 경우 상기 보강판(150)과 TPO시트(120)를 결합시키기 위한 별도의 접착제(160)가 필수적으로 요구되지만, 상기 TPO시트(120)가 평판 형상의 보강판(150) 상면에 전체가 밀착되므로 상기 TPO시트(120)의 평탄도는 현저히 향상된다는 장점이 있다. 즉, 상기 TPO시트(120)는 보강판(150)이 변형되지 아니하는 한 평면 형태를 안정적으로 유지할 수 있으므로, 데크패널(100)의 외관이 매우 미려해진다는 장점이 있다.As such, when the foam 130 is not injected between the reinforcing plate 150 and the TPO sheet 120 and is directly bonded to the reinforcing plate 150 and the TPO sheet 120, the reinforcing plate 150 and the TPO sheet ( Although a separate adhesive 160 is required for bonding the 120, the flatness of the TPO sheet 120 is significantly because the TPO sheet 120 is in close contact with the upper surface of the flat reinforcement plate 150. It has the advantage of being improved. That is, since the TPO sheet 120 can stably maintain a flat shape as long as the reinforcing plate 150 is not deformed, the TPO sheet 120 has an advantage that the appearance of the deck panel 100 becomes very beautiful.
또한, TPO시트(120)와 보강판(150)이 직접 결합되면 상기 보강판(150)은 TPO시트(120)가 휘어지거나 변형되지 아니하도록 상기 TPO시트(120)를 직접적으로 지지하는 기능을 수행하게 되므로, 상기 TPO시트(120)에 하중이나 비틀림응력이 인가되더라도 상기 TPO시트(120)가 꺾이거나 휘어지지 아니하며, 상기 TPO시트(120)의 외측면에 충격이 인가되더라도 상기 TPO시트(120) 중 충격이 인가된 부위가 오목하게 변형되지 아니하게 된다는 효과를 얻을 수 있다.In addition, when the TPO sheet 120 and the reinforcing plate 150 is directly coupled, the reinforcing plate 150 performs a function of directly supporting the TPO sheet 120 so that the TPO sheet 120 is not bent or deformed. Therefore, even if a load or torsional stress is applied to the TPO sheet 120, the TPO sheet 120 is not bent or bent, and even if an impact is applied to the outer surface of the TPO sheet 120, the TPO sheet 120 It is possible to obtain an effect that the site to which the impact is applied is not concavely deformed.
본 실시예에서는 강판(110)이 절곡된 형태로 제작되고 TPO시트(120)가 평면 형태를 이루는 경우만을 도시하고 있으나, 상기 강판(110) 및 TPO시트(120)의 형태는 데크패널(100)의 용도에 따라 다양하게 변경될 수 있다. 즉, 상기 강판(110)과 TPO시트(120)가 모두 평면 형태로 제작될 수도 있고, 상기 강판(110)과 TPO시트(120)가 모두 절곡된 형태로 제작될 수도 있으며, 상기 강판(110)은 평면 형태로 제작되고 TPO시트(120)는 절곡된 형태로 제작될 수도 있다.In this embodiment, only the case where the steel sheet 110 is manufactured in a bent form and the TPO sheet 120 has a flat shape, the shape of the steel sheet 110 and the TPO sheet 120 is a deck panel 100 It can be changed in various ways depending on the purpose of use. That is, both the steel sheet 110 and the TPO sheet 120 may be manufactured in a flat form, or the steel sheet 110 and the TPO sheet 120 may be manufactured in a bent form, or the steel sheet 110. Silver may be manufactured in a flat form and the TPO sheet 120 may be manufactured in a bent form.
도 9는 본 발명에 의한 데크패널 제5 실시예의 단면도이고, 도 10은 본 발명에 의한 데크패널 제6 실시예의 단면도이다.9 is a cross-sectional view of a deck panel fifth embodiment according to the present invention, and FIG. 10 is a cross-sectional view of a deck panel sixth embodiment according to the present invention.

A protruding end 152 is formed at the right side, and a seating end 154 having a concave shape may be provided at the other side of the connection direction (the left side in FIGS. 7 and 8) to allow the protruding end 152 to be seated.
이와 같이 보강판(150)에 돌출단(152) 및 안착단(154)이 마련되면, 두 개의 데크패널(100)을 연결할 때 어느 하나의 데크패널(100) 돌출단(152)이 다른 하나의 데크패널(100) 안착단(154)에 안착되어 고정되는바, 상기 두 개의 데크패널(100) 간의 연결이 보다 안정적으로 이루어질 수 있다는 장점이 있다.As such, when the protruding end 152 and the seating end 154 are provided on the reinforcing plate 150, when one deck panel 100 is connected, the protruding end 152 of the other deck panel 100 is connected to the other. The deck panel 100 is seated on and fixed to the seating end 154, and there is an advantage that the connection between the two deck panels 100 can be made more stably.
이때, 상기 보강판(150)에 돌출단(152) 및 안착단(154)이 마련되는 구조는, 도 9에 도시된 바와 같이 발포체(130) 사이에 보강판(150)이 삽입되는 경우에도 적용될 수 있고, 도 10에 도시된 바와 같이 접착제(160)에 의해 TPO시트(120) 저면에 보강판(150)이 접착되는 경우에도 적용될 수 있다. 이와 같이 보강판(150)이 발포체(130) 사이에 삽입되거나 TPO시트(120) 저면에 접착되는 경우의 구성상 특징은 도 7 및 도 8을 참조하여 설명한 바 있으므로, 이에 대한 상세한 설명은 생략한다.In this case, the structure in which the protruding end 152 and the seating end 154 are provided on the reinforcing plate 150 may be applied even when the reinforcing plate 150 is inserted between the foams 130 as shown in FIG. 9. 10, the reinforcement plate 150 may be applied to the bottom surface of the TPO sheet 120 by the adhesive 160, as shown in FIG. 10. Thus, since the reinforcing plate 150 is inserted between the foam 130 or bonded to the bottom surface of the TPO sheet 120 has been described with reference to Figures 7 and 8, a detailed description thereof will be omitted. .
이상, 본 발명을 바람직한 실시예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 특정 실시예에 한정되는 것은 아니며, 첨부된 특허청구범위에 의하여 해석되어야 할 것이다. 또한, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다.As mentioned above, although this invention was demonstrated in detail using the preferable Example, the scope of the present invention is not limited to a specific Example and should be interpreted by the attached Claim.
