Claims (2)
- 복수 개의 강화 섬유로 이루어지는 섬유속(束)을 분산시켜서, 그 주위를 모재(母材) 수지로 경화시킨 합성 침목(枕木)에 있어서,상기 섬유속에는 상기 섬유속의 길이 방향으로부터 만곡되어 편평한 형상으로 눌려 찌부러진 팽출부(膨出部)가 소정의 간격으로 형성되어 있으며, 상기 섬유속은 침목 제조용 금형에 제품 사양의 높이 이상으로 적층되고, 모재 수지인 발포제를 포함하는 경질 우레탄 액을 소정량 투입 후 상기 제품 사양의 높이까지 압축하여 성형되는 것을 특징으로 하는 합성 침목.
- 제1항에 있어서,상기 섬유속을 상기 길이 방향으로부터 만곡시키며 소정의 반경을 갖는 돌출부가 상기 섬유속의 길이 방향과 직교하는 방향으로 연장되는 상가압구(上加壓駒)와 상기 돌출부에 대응하는 오목부를 갖는 하가압부가 서로 계합하여 가압됨으로써, 상기 팽출부가 성형되는 것을 특징으로 하는 합성 침목.
