<P>PROBLEM TO BE SOLVED: To prevent loosening of a bolt and breakage of a crossing by strongly connecting a manganese crossing part and an outer wing rail part. <P>SOLUTION: Rail steel outer wing rail parts 2 and 2 are attached to respective outer sides of inner wing rail parts 10 and 10 of a manganese crossing part 1. The manganese crossing part 1 and the respective outer wing rail parts 2 are tightened with bolts 3 at a plurality of intervals in the view from a plane. Inner side attaching parts 2a of the respective outer wing rail parts 2 are formed on a first vertical surface 20. Respective abutting surfaces 12, 12, 12... by the plurality of bolts 3, 3, 3... of respective outer side attaching parts 10a and 10a of the inner wing rail parts 10 and 10 are turned to second vertical surfaces 11. Recessed parts 13, 13, 13... are formed between the abutting surfaces 12, 12, 12... by the plurality of bolts 3, 3, 3... and turned to a non-abutting part with the first vertical surface 20. The respective second vertical surfaces 11 are bonded to the first vertical surface 20 of the outer wing rail part 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
