Abstract

The present invention relates to a sandwich panel for fire prevention and a manufacturing method thereof, comprising: a first board and a second board arranged to be spaced at both sides of the outer surface; a foam material filled between the first board and the second board; and a blocking frame which is buried in the foam material, and which closely contacts with the first board and the second board, and which is formed in a direction crossing at a right angle to the direction of progress of the first board and the second board. Therefore, movement of flame is blocked by burying a blocking member in the foam material filled therein, thereby overcoming a weakness of a conventional sandwich panel which performed a stovepipe function (forming a stack), triggering movement of flame in case of a fire, and providing the advantage of enhancing safety by adding a fire-retardant and nonflammable function to the foam material filled therein.

Description

화재 방지용 샌드위치 판넬 및 그 제조방법{Sandwich Panel for prevent fire and thereof manufacture method}FIELD OF THE INVENTION [0001] The present invention relates to a sandwich panel for preventing fire,

본 발명은 화재 방지용 샌드위치 판넬 및 그 제조방법에 관한 것으로, 더욱 상세하게는 가건물의 외장이나 기타 건축물등의 외벽 또는 내, 외장재로 사용되는 샌드위치 판넬에 관한 것이다.FIELD OF THE INVENTION The present invention relates to a sandwich panel for fire prevention and a method of manufacturing the same, and more particularly, to a sandwich panel used as an outer wall or an inner or outer wall of a canopy or other building.

일반적으로 건축물에 사용되는 내, 외장재는 건축물의 내외부, 벽 또는 천정 등에 설치하여 건축물에 방음, 방수, 단열 및 미려함과 건물 보호 등의 기능을 수행하는 것이다.In general, interior and exterior materials used in buildings are installed inside and outside of buildings, walls, or ceilings to perform soundproofing, waterproofing, insulation, beauty and building protection.

하지만, 통상적으로 사용되고 있는 내, 외장재로서의 판넬은 샌드위치(sand witch)형을 취하는 겹판형상으로서, 중앙으로는 스티로폼이 형성되고 상기 스티로폼의 양측으로는 불연성 판재인 박판의 철판을 접착하여 형성하였다.However, conventionally used panels as interior and exterior materials are formed in the shape of a laminate having a sand witch type, in which styrofoam is formed at the center and an iron plate of a thin plate, which is a nonflammable plate, is bonded to both sides of the styrofoam.

종래 샌드위치 판넬은 일정크기의 블럭으로 형성된 스치로폼을 롤형상으로 형성된 철판이나 알루미늄판재를 상하부에 배치하고, 그 사이에 스치로폼을 공급하고, 상하 롤러를 통과하면서 적정 두께로 압착된 후 경화시켜 생산된다.Conventionally, a sandwich panel is produced by arranging a steel foil or an aluminum plate, which is formed of a block of a predetermined size, in a roll shape and supplying the steel foil between the upper and lower portions.

그러나 상기와 같은 종래의 샌드위치 판넬은 화재발생시 내부의 스치로폼이 쉽게 연소되고, 양측의 판재에 의해 연통과 같은 기능을 하게 되어 화염이 상부로 급격히 상승하게 되어 화재를 크게 번지게 하는 문제점이 있었다. However, in the conventional sandwich panel as described above, the internal styrofoam easily burns when a fire occurs, and functions as a communication by the plates on both sides, so that the flame rises sharply to the upper part, thereby causing a problem of a large fire.

또한 스치로폼의 연소시 발생되는 유독 가스에 의해 질식사를 유발하는 문제점이 있었다. In addition, there is a problem of causing suffocation by toxic gas generated when the styrofoam is burned.

또한, 본 발명과 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우 그 상세한 설명은 생략한다.In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

여기서, 첨부된 도면들은 기술의 구성 및 작용에 대한 설명과 이해의 편의 및 명확성을 위해 일부분을 과장하거나 간략화하여 도시한 것으로서, 각 구성요소가 실제의 크기와 정확하게 일치하는 것은 아니다.Here, the attached drawings are exaggerated or simplified in order to facilitate understanding and clarification of the structure and operation of the technology, and the components do not exactly coincide with actual sizes.

도 1 내지 도 3에 나타낸 바와 같이, 본 발명의 일 실시태양에 따른 샌드위치 판넬(A)은, 외면 양측에 이격 배치되는 제1판재(100) 및 제2판재(200)와, 제1판재(100) 및 제2판재(200) 사이에 충진되는 폼 소재(300)를 포함하고, 폼 소재(300)에 매립되며, 제1판재(100) 및 제2판재(200)에 밀착되되 제1판재(100) 및 제2판재(200)의 진행방향과 직각되는 방향으로 형성되는 차단프레임(400);을 포함하여 이루어진다. 1 to 3, a sandwich panel A according to an embodiment of the present invention includes a first plate 100 and a second plate 200 spaced from both sides of the outer surface, 100 and the second plate 200 and is embedded in the foam material 300 and is in close contact with the first plate 100 and the second plate 200. The first plate 100 and the second plate 200, (400) formed in a direction perpendicular to the traveling direction of the first plate member (100) and the second plate member (200).

폼 소재(300)는 스치로폼, 올레핀 발포체 등이 사용된다. Styrofoam, olefin foam, or the like is used as the foam material 300.

폼 소재(300)에는 난연성 소재가 혼합된다. 일 예에 따르는 난연성 소재는 세라믹재 또는 진흙이다. The foam material 300 is mixed with a flame-retardant material. The flame retardant material according to one example is a ceramic material or clay.

바람직하게는 상기 폼 소재(300) 100 중량부를 기준으로 진흙이 1~30중량부가 혼합된다.Preferably, 1 to 30 parts by weight of the clay is mixed with 100 parts by weight of the foam material 300.

진흙이 1중량부 이하로 혼합되면 난연 성능을 기대하기 어렵고, 30중량부 이상으로 혼합되면 무게가 무거워지고 폼 소재(300)가 쉽게 부서지는 단점이 발생될 우려가 있다. When the mud is mixed in an amount of 1 part by weight or less, flame retardant performance is difficult to expect. If the mud is mixed in an amount of 30 parts by weight or more, the weight becomes heavy and the foam material 300 may easily break.

한편 상기한 본 발명에 따르는 샌드위치 판넬의 제조방법에 대해 도 3을 토대로 설명하면 다음과 같다.A method of manufacturing the sandwich panel according to the present invention will be described with reference to FIG.

본 발명에 따르는 샌드위치 판넬의 제조방법은, 제1판재(100) 및 제2판재(200)가 수납된 제1,2드럼(R1,R2)로부터 제1판재(100) 및 제2판재(200)가 각기 인출되고, 상기 인출되는 제1판재(100) 및 제2판재(200)가 상하부에 이격되게 배치되어 인출되도록 하는 1단계(S1); 상기 이격된 제1판재(100) 및 제2판재(200) 사이에 폼 소재(300)가 공급되어 1차 조립체(500)가 형성되고, 상기 1차 조립체(500)가 가압히팅로울러(600) 사이를 통과하면서 두께가 축소되어 2차 조립체(520)가 형성되도록 하는 2단계(S2); 상기 2단계(S2)의 2차 조립체(520)를 일정 간격으로 절단하여 제품(P)을 완성하는 3단계(S3);를 포함하여 이루어진다. A method for manufacturing a sandwich panel according to the present invention is a method for manufacturing a sandwich panel from a first plate 100 and a second plate 200 (hereinafter, referred to as " first plate 100 ") from first and second drums R1 and R2 accommodating a first plate 100 and a second plate 200 (S1) for drawing out the first sheet material 100 and the second sheet material 200 so that the first sheet material 100 and the second sheet material 200 are spaced apart from each other; A foam material 300 is supplied between the spaced first plate 100 and the second plate 200 to form a primary assembly 500. The primary assembly 500 is pressed against the pressurizing heating roller 600, (S2) of forming the secondary assembly 520 by reducing the thickness of the secondary assembly 520 while passing between the first assembly 520 and the second assembly 520; And a third step (S3) of cutting the secondary assembly 520 of the second step S2 to a predetermined interval to complete the product P.

상기 1단계(S1)는 제1판재(100) 및 제2판재(200)가 권취된 제1,2드럼(R1,R2)을 준비한다. In the first step S1, the first and second drums R1 and R2 wound with the first plate 100 and the second plate 200 are prepared.

제1,2드럼(R1,R2) 사이에는 폼 소재 공급부(F)를 배치한다. 폼 소재(300)는 스치로폼, 올레핀 발포체 등이 사용된다. A foam material supply unit F is disposed between the first and second drums R1 and R2. Styrofoam, olefin foam, or the like is used as the foam material 300.

상기 2단계(S2)는 제1판재(100) 및 제2판재(200)를 공급하고, 그 사이에 폼 소재(300)를 공급하여 1차 조립체(500)가 형성되도록 한다.In the second step S2, the first plate material 100 and the second plate material 200 are supplied and the foam material 300 is supplied therebetween to form the primary assembly 500.

1차 조립체(500)는 상하에 배치된 가압히팅로울러(600) 사이를 통과하면 압착 및 가열되어 두께가 50% 이하로 납작하게 축소되어 2차 조립체(520)가 수득된다. When the primary assembly 500 passes between the upper and lower pressurizing heating rollers 600, the primary assembly 500 is compressed and heated to be flattened to a thickness of less than 50% to obtain a secondary assembly 520.

가압히팅로울러(600)의 양측에는 길이방향으로 가이드벽(700)이 형성된다. At both sides of the pressurizing heating roller 600, a guide wall 700 is formed in the longitudinal direction.

따라서 가압 과정에서 측면으로 폼 소재(300)가 흘러나오지 않도록 가이드벽(700)이 차단하게 됨으로써 적정한 두께를 갖도록 성형된다. Therefore, the guide wall 700 is cut off so that the foam material 300 does not flow out to the side in the pressing process, so that it is formed to have a proper thickness.

여기서 상기 가압히팅로울러(600)에 1차 조립체(500)가 진입하기 전에 측면으로부터 차단프레임(400)을 삽입하는 차단프레임 삽입공정(S2-2)을 포함한다. Here, the step of inserting the shielding frame 400 from the side before the primary assembly 500 enters the pressurizing heating roller 600 includes a step of inserting the shielding frame S2-2.

상기 차단프레임 삽입공정(S2-2)은 1차 조립체(500)의 이송 방향에 대해 차단프레임(400)을 비스듬히 삽입되도록 하는 것이다. The intercepting frame inserting step S2-2 is to insert the intercepting frame 400 obliquely with respect to the conveying direction of the primary assembly 500. [

또한 상기 차단프레임(400)의 삽입 속도는 1차 조립체(500)의 이송 속도 대비 1/3~2/3의 속도로 삽입되는 것이다. Further, the insertion speed of the cut-off frame 400 is inserted at a speed of 1/3 to 2/3 of the feed speed of the primary assembly 500.

도 2에 나타낸 바와 같이, 차단프레임(400)을 측면에서 비스듬히 삽입하되 저속으로 삽입함으로써 폼 소재(300)의 뭉침이나 끊김을 방지하여 내부에 공백이 생기는 폐단을 방지할 수 있고 아울러 폼 부재(300)의 이송 압력으로 인해 차단프레임(400)이 휘어질 위험성을 방지하면서 삽입할 수 있게 된다. As shown in FIG. 2, the blocking frame 400 is inserted obliquely from the side face, and inserted at a low speed, thereby preventing the foam material 300 from being clumped or broken so as to prevent clogging of the inside of the foam material 300, The blocking frame 400 can be inserted while preventing the risk of bending.

한편 상기 1차 조립체(500)는 이송과 정지 작동을 일정 시간 간격으로 반복하도록 설정될 수 있다. Meanwhile, the primary assembly 500 can be set to repeat the feeding and stopping operations at predetermined time intervals.

따라서 상기 차단프레임(400)은 1차 조립체(500)의 이송이 일시 정지된 상태에 실시된다. Accordingly, the cut-off frame 400 is performed while the primary assembly 500 is temporarily stopped.

이때에는 비교적 빠른 삽입속도로 신속하게 차단프레임(400)을 삽입할 수 있다. 차단프레임(400)의 삽입은 작업자에 의한 수동방식 또는 자동공급장치에 의한 자동방식을 취할 수 있다. At this time, the intercepting frame 400 can be inserted at a relatively fast insertion speed. The interception frame 400 may be inserted manually by an operator or automatically by an automatic feeder.

여기서 상기 2단계(S2)는 상기 폼 소재(300)에 혼합되는 난연성 소재를 더 포함할 수 있다. The second step S2 may further include a flame retardant material to be mixed with the foam material 300.

상기 난연성 소재는 세라믹재 또는 진흙이다. The flame-retardant material is a ceramic material or clay.

바람직하게는 상기 폼 소재(300) 100 중량부를 기준으로 진흙이 1~30중량부가 혼합된다.Preferably, 1 to 30 parts by weight of the clay is mixed with 100 parts by weight of the foam material 300.

진흙이 1중량부 이하로 혼합되면 난연 성능을 기대하기 어렵고, 30중량부 이상으로 혼합되면 무게가 무거워지고 폼 소재가 쉽게 부서지는 단점이 발생될 우려가 있다. When the mud is mixed in less than 1 part by weight, it is difficult to expect a flame retardant performance. If the mud is mixed in an amount of more than 30 parts by weight, the weight becomes heavy and the foam material easily breaks.

상기 2차 조립체(520)는 냉각로울러(650)를 통과하면서 냉각된다.The secondary assembly 520 is cooled while passing through the cooling rollers 650.

이후 커팅기(670)에 의해 일정 길이로 절단되어 최종 샌드위치 판넬(P)이 완성된다. Thereafter, the cutter 670 is cut to a predetermined length to complete the final sandwich panel P.

따라서 본 발명의 샌드위치 판넬(P)은 제1판재(100) 및 제2판재(200) 사이에 등간격으로 다수의 차단프레임(400)이 직각방향으로 삽입됨으로써 내부의 폼 소재(300)를 구역별로 분할할 수 있고, 화재로 인한 연소시 분할된 구역내에서 타 구역으로 화염의 이동을 방지할 수 있어 방염성능이 월등히 향상될 수 있다. Accordingly, the sandwich panel P of the present invention is formed by inserting a plurality of cut-off frames 400 at regular intervals between the first plate 100 and the second plate 200 in a direction perpendicular to the first plate 100, It is possible to prevent the flame from moving to another zone in the divided zone when burning due to the fire, and the flame resistance performance can be greatly improved.
