본 발명은 건축물 내부에 구비되는 방화셔터의 비상도어용 구비되어 힌지의 구조에 관한 것으로, 보다 상세하게는 복수개의 슬래트에 각각 결합된 힌지부재간의 결합을 견고하게 하여 셔터가 권취되거나 펼쳐지더라도 힌지부재간의 연결이 이탈되는 것이 방지되는 방화셔터의 비상도어용 힌지구조에 관한 것이다. The present invention relates to the structure of the hinge is provided for the emergency door of the fire shutter provided in the interior of the building, and more particularly, the hinge member is firmly coupled to the hinge member coupled to each of the plurality of slats even if the shutter is wound or unfolded The hinge structure for the emergency door of the fire prevention shutter is prevented from being separated.

일반적으로 방화셔터는 건축물 내부의 통로상에 설치되는 것으로, 평상시에는 사람의 출입을 차단하는 역할을 하며 화재시에는 화염이나 유독가스 등이 통로를 따라 확산되는 것을 방지하는 역할을 한다. In general, the fire shutter is installed on the passage inside the building, and serves to block the entry and exit of people in normal times, and to prevent the spread of flames or toxic gases along the passage in case of fire.

도 1은 종래 방화셔터의 일례를 도시한 것이고, 도 2는 그 중 힌지부재를 도시한 것으로, 도시된 바와 같이, 구동장치가 내장설치된 셔터박스(1)와, 이 셔터박스(1)에 권취되어 수평방향으로 연장되며 상하로 결속된 다수의 슬래트(3)로 이루어진 셔터판(2)으로 구성되어, 이 셔터판(2)은 셔터박스(1) 내로 권취되어 수납되 거나 인출되어 건물의 통로 등을 차단한다. 그리고, 이러한 셔터판(2)의 차단시에 비상탈출의 통로를 확보하기 위한 도어(4)가 설치된다. FIG. 1 shows an example of a conventional fire shutter, and FIG. 2 shows a hinge member, and as shown, a shutter box 1 having a built-in driving device and a winding around the shutter box 1 as shown in FIG. It consists of a shutter plate (2) consisting of a plurality of slats (3) that extend in the horizontal direction and are bound up and down, the shutter plate (2) is wound into the shutter box (1) is accommodated or withdrawn and the passage of the building Block etc. Then, a door 4 for securing an emergency escape passage at the time of blocking the shutter plate 2 is provided.

이때, 이 도어(4)는 셔터판(2)과 동일하게 다수의 슬래트(3)를 상하방향으로 결속하여 이루어지고, 도어(4)의 일측에 구비된 힌지부재(5)에 의해가 셔터판(2)에 회동가능하게 장착된다. 그리고, 상기 힌지부재(5)는 도어(4)의 개폐를 위한 것이기도 하지만 유독가스를 차단하는 기능이 요구되고 있다. At this time, the door 4 is formed by binding a plurality of slats 3 in the up and down direction similarly to the shutter plate 2, and is closed by the hinge member 5 provided on one side of the door 4. (2) is rotatably mounted. In addition, although the hinge member 5 is used for opening and closing the door 4, a function of blocking toxic gas is required.

한편, 상기 힌지부재(5)는 셔터판(2)에 고정 설치되는 제1힌지편(6)과 도어(4)에 고정 설치되는 제2힌지편(7)이 도시안된 스프링과 힌지핀에 의해 힌지결합되어 힌지핀을 중심으로 회동되도록 구성된다. 이때, 제1 및 제2힌지편(6, 7)의 상단에는 결합홈(8)이 각각 형성되고 하단에는 상기 결합홈(8)에 삽입되는 각각 결합돌기(9)가 형성되어, 상측 힌지부재(5)와 하측 힌지부재(5)간에 결합된다. 그리고, 도시된 바와 같이, 상기 결합홈(8)은 전후면이 개방되어 셔터판(2)과 도어(4)가 동시에 권취될 때 결합돌기(9)가 결합홈(8)에서 회동되도록 구성된다. 한편, 제1 및 제2힌지편(6, 7)의 상하단에는 화염을 차단하는 차폐판(10)이 형성된다. On the other hand, the hinge member 5 is formed by a spring and a hinge pin, in which the first hinge piece 6 fixed to the shutter plate 2 and the second hinge piece 7 fixed to the door 4 are not shown.
