A Threshold Rise-fall Apparatus for Fire Prevention Door
The present invention relates to an automatic threshold ascending and descending device for a door frame for a fire door. According to the present invention, a threshold of a door frame is divided into three sections in the longitudinal direction in the door frame in which a fire door panel is installed. Both sides of the threshold are formed as a fixing threshold, and the center is formed as an ascending and descending center threshold. Therefore, the ascending and descending center threshold can ascend and descend by the automatic threshold ascending and descending device installed on the lower side of the inner part of the ascending and descending center threshold. The automatic threshold ascending and descending device for a door frame for a fire door can be automatically or manually controlled. According to the present invention, the automatic threshold ascending and descending device for a door frame for a fire door can prevent casualties by easily moving a load for moving, a wheelchair, and a bed, using the lowered threshold by smoothly obtaining a path by usually reducing the height of the threshold by dropping the ascending and descending center threshold down by the automatic threshold ascending and descending device. The automatic threshold ascending and descending device can maintain the ascending and descending center threshold while the ascending and descending center threshold is raised by the automatic threshold ascending and descending device in emergency such as fire. Therefore, the automatic threshold ascending and descending device can support the fire door panel and prevent the spread of smoke by blocking the smoke.
본 발명은, 방화문짝이 설치되는 문짝틀에서 문짝틀의 문턱을 길이방향으로 3분할하여 양측은 고정문턱으로 형성하고, 중앙은 승하강중앙문턱으로 형성하여, 상기 승하강중앙문턱을 승하강중앙문턱의 내부 하측에 설치된 문턱자동승하강장치에 의해 승강 및 하강시킬 수 있도록 하되, 상기 문턱자동승하강장치는 자동 또는 수동 조작할 수 있도록 된 방화문용 문짝틀의 문턱자동승하강장치이다. 본 발명은, 평상시에는 승하강중앙문턱을 문턱자동승하강장치에 의해 하강시켜 문턱의 높이를 낮춰줌으로써 통행경로를 원활하게 확보하여 낮춰진 문턱을 통해 이삿짐이나 휠체어 및 침대 등을 용이하게 이동시켜 인명사고 등을 예방할 수 있고, 화재 등의 비상시에는 승하강중앙문턱을 문턱자동승하강장치에 의해 승하강중앙문턱을 승강시킨 상태로 유지시켜 줌으로써, 방화문짝을 억류 지지시키고 연기를 차단하여 연기의 확산을 방지할 수 있다.
