연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A leveling joint between connected ends of two rails of different profiles is provided with a connector/juncture bar members which is configured to fit with and engage corresponding surfaces formed on the rails when the rails are connected together. The leveling joint so formed is one with increased strength, with ease and accuracy of alignment during assembly. The leveling joint is formed of several structural members, yet functions as and affords the strength and stability of a solid, unitary assembly.

1. A leveling joint connector bar for connecting adjoining end portions of rails in a track structure having different profiles, the end portions of the rails being connected having vertical flat surfaces formed on their respective web portions and further having horizontal flat surfaces formed on sloped upper surfaces of their base portions, the leveling joint connector bar comprising: an elongate joint body to span the adjoining end portions of the rails to be joined and having a number of connector holes formed therein aligned with connector holes in web portions of the adjoining end portions of the rails to be joined;an engaging shoulder member formed with and extending along the length of the joint body, the engaging shoulder member having a number of connector holes formed therein aligned with the connector holes in the joint body and the connector holes in web portions of the adjoining end portions of the rails to be joined;the engaging shoulder member having an inwardly extending portion having a flat vertical contact surface thereon for engaging the flat vertical surfaces formed on the web portions of the adjoining end portions of the rails to be joined;the joint body being located outwardly of engaging shoulder member and adapted to be fitted between the head and base portions of the adjoining end portions of the rails to be joined;the joint body having a downwardly extending contact rib member formed along its length;the contact rib member having a horizontal contact surface formed thereon for engaging with the corresponding horizontal flat surfaces formed on the sloped surface of a base portion of the adjoining end portions of the rails to be joined. 2. The leveling joint connector bar of claim 1 wherein the adjoining end portions of the rails to be joined are different in width in their head portions and wherein the joint body is of a with conforming to the different widths of the adjoining end portions of the rails to be joined. 3. The leveling joint connector bar of claim 2, further comprising the adjoining end portions of the rails being of different height between the head and base portions. 4. The leveling joint connector bar of claim 3, wherein the joint body is of a height along of its longitudinal extent conforming to different heights of the adjoining end portions of the rails to be joined. 5. The leveling joint connector bar of claim 1, wherein the horizontal flat surface on the rail base portion is formed at a location between an outer edge of base portions and the webs of the adjoining end portions of the rails. 6. The leveling joint connector bar of claim 1, wherein the end portions of the rails being connected further have horizontal flat surfaces formed beneath their head portions and further including: an upper contact rib formed on an upper surface of the joint body extending along its length, the upper contact rib having a horizontal upper contact surface thereon for engaging the horizontal flat surfaces below the head portions of the rails to be joined. 7. The leveling joint connector bar of claim 6, wherein the horizontal flat surface below the head portions of the rail are formed extending inwardly from side surfaces of the head portions of the adjoining end portions of the rails to be joined. 8. The leveling joint connector bar of claim 1, wherein the joint body has a support segment around the central port and extending outwardly beyond the head portions of the rails to provide additional strength to the assembled leveling joint. 9. A rail track structure formed at adjoining end portions of rails have differing rail profiles, comprising: a first track segment and a second track segment, each having a web portion, a base portion and a head portion, the first and second track segments having differing rail profiles;the web portions of the first and second track segments having vertical flat surfaces formed thereon;the web portions further having a number of connector holes formed therein for the passage of connectors at their end portions;the head portions of the first and second track segments having horizontal flat surfaces formed on lower portions thereof;the base portion of the first track segment having horizontal flat surfaces formed on sloped upper portions thereof;an elongate connector bar to span the adjoining end portions of the first and second track segments to be joined and having a number of connector holes formed therein aligned with connector holes in web portions of the adjoining end portions of the first and second track segments to be joined;an engaging shoulder member extending along the length of the connector bar, the engaging shoulder member having a number of connector holes formed therein aligned with the connector holes in the connector bar and the connector holes in web portions of the adjoining end portions of the first and second track segments to be joined;the engaging shoulder member having an inwardly extending portion having a flat vertical contact surface thereon for engaging the flat vertical surfaces on the web portions of the adjoining end portions of the first and second track segments to be joined;the connector bar being located outwardly of the engaging shoulder and adapted to be fitted between the head and the base portions of the adjoining end portions of the first and second track segments to be joined;the connector bar having a downwardly extending contact rib member formed along its length; andthe contact rib member having horizontal flat contact surfaces formed thereon for engaging with corresponding horizontal flat surfaces formed on sloped surfaces of base portions of the adjoining end portions of the first and second track segments to be joined. 10. The rail track structure of claim 9, wherein the elongate connector member is located on a first side of the adjoining end portions of the first and second track segments, and further including: a second elongate connector bar to span the adjoining end portions of the first and second track segments to be joined and having a number of connector holes formed therein aligned with connector holes in the elongate connector member and the web portions of the adjoining end portions of the first and second track segments to be joined;an engaging shoulder member extending along the length of the second connector bar, the engaging shoulder member having a number of connector holes formed therein aligned with the connector holes in the second connector bar and the connector holes in the elongate connector member and the web portions of the adjoining end portions of the first and second track segments to be joined;the engaging shoulder member having an inwardly extending portion having a flat vertical contact surface thereon for engaging the flat vertical surfaces on the web portions of the adjoining end portions of the first and second track segments to be joined;the second connector bar being located outwardly of the engaging shoulder and adapted to be fitted between the head and the base portions of the adjoining end portions of the first and second track segments to be joined;the second connector bar having a downwardly extending contact rib member formed along its length; andthe contact rib member of the second connector bar having horizontal contact surfaces formed thereon for engaging with corresponding horizontal flat surfaces formed on sloped surfaces of base portions of the adjoining end portions of the first and second track segments to be joined.
