Summary:A flexible protective device (1) for construction, according to the present invention, includes a rotating connector (20) and a finishing connector (30). In a state in which a flexible protective tube (10) made of polyethylene wraps a high-voltage wire (100), the flexible protective tube (10) is coupled to the rotating connector (20) by the opening due to a slit incision structure in one side of the rotating connector (20). Therefore, the rotating connector (20) is located in the middle section of the flexible protective tube (10) and has a danger sign (40) hanging thereon. The finishing connector (30) secures both ends of the flexible protective tube (10) to the high-voltage wire (100). The device eliminates all risks of electric shock or falling accidents, caused by direct live wire works, through indirect live wire works. In particular, the protective tubes are connected in a plurality of connection structures by the rotating connectors. Therefore, the protective tube can be manufactured as a short length protective tube to fit the narrow space of an insulating bucket, and can be bent at a predetermined level, thereby being usable for straight and curved (i.e., jumper wire) wires. 본 발명의 건축용 플렉시블 방호장치(1)는 폴리에틸렌 소재의 플렉시블 방호관(10)이 고압전선(100)을 감싸 쌍태에서 한쪽 트임 절개 구조에 의한 벌어짐으로 결합되어 상기 플렉시블 방호관(10)의 중간 구간에 위치되어 위험 표지판(40)이 걸리는 회전 연결재(20) 및 상기 플렉시블 방호관(10)의 양쪽 끝부를 상기 고압전선(100)과 고정시켜 주는 마감 연결재(30)로 구성됨으로써 직접 활선작업에 의한 감전 사고나 추락사고 위험성을 간접 활선 작업으로 모두 해소하여 주고, 특히 방호관이 회전 연결재에 의해 복수개 연결 구조로 이어짐으로써 절연 버켓의 협소 공간에 맞게 짧은 길이의 방호관으로 제조 가능하면서 일정한 휨이 가능하여 직선과 곡선(즉, 점퍼선)의 전선에도 사용 가능한 특징을 갖는다.
