Description

포물선형 단부 체결구Parabolic End Fasteners

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

첨부도면은 본 발명에 의한 단부 체결구(端部締結具)가 유리섬유봉의 한쪽 단부에 부착된 상태를 나타내는 단면도.The accompanying drawings are sectional drawing which shows the state in which the end fastener which concerns on this invention was attached to one end of a glass fiber rod.

Claims (1)

봉과 이 봉을 접합시킬 수 있는 적당한 에폭시를 수용하기 위한 중공(中空)의 내부공간을 포함하며, 이 내부공간은 개구부와 단부로 형성되고, 내부공간의 축벽은 다수의 리브부재 사이에 간격을 두고 위치한 다수의 포물선형 압축홈들로 형성되며, 이들 리브부재와 포물선형 압축홈 사이의 각도는 내부공간의 상기 개구부로부터 상기 단부로 갈수록 각각의 압축홈에 대해 감소함으로써 내부공간의 개구부로부터 단부로 갈수록 각각의 압축홈 및 대응지역에 대해 인장하중 및 압축하중이 감소하도록 구성되어 있는, 유리섬유봉 혹은 플라스틱봉의 단부에 장착되는 단부 체결구.A hollow interior space for accommodating the rod and a suitable epoxy to bond the rod, the interior space being formed by an opening and an end, the axial wall of the interior space being spaced between the plurality of rib members Formed with a plurality of parabolic compression grooves located, the angle between these rib members and the parabolic compression grooves decreasing with respect to each compression groove toward the end from the opening of the interior space, and toward the end from the opening of the interior space. End fasteners mounted to the ends of glass fiber rods or plastic rods configured to reduce the tensile and compressive loads for each compression groove and corresponding zone. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
