摘要

(57) [Abstract] [Configuration] In fitting which is formed in a tapered shape that an abutment surface which abuts the flange portion of the frame cross the extremely slightly inclined from the longitudinal direction central portion at both ends to be connected, the gantry to be connected It was constructed a connection frame for rigid catenary by connecting each other. [Effect] is stand mutual connection to be connected, very quickly a simple operation of only fastening the frame to the fitting by means of bolts and nuts or rivets, and, certainly strongly can be performed, Moreover, the contact surface of the fitting which abuts the flange portion of the pedestal cross by tapered to extremely slightly inclined to the opposite ends from the longitudinal central portion, bending due to its own weight to the cradle even occur, and the pedestal Since the connection part is slightly recessed or flat to the wayside direction, fear is no such as away-rays pantograph bounce at the connection of the frame.
