GROOVE RAIL Russian patent published in 2008 - IPC E01B5/04 

FIELD: building, road works.

SUBSTANCE: invention concerns to the rail for movement of rail vehicles supplied with wheels with flanges. The groove rail contains supplied with working rail (2), rut (3), and also check rail (4) head of (5) rail, web of rail (6), rail base (7), and also lateral chambers (8, 9) located between the head (5) and the base (7) of the rail. The working rail (2) has in direction to rut (3) side face (10) guiding a vehicle which at depth of rut (T)>20 mm, i.e. at depth of a trench, rather basically an axis passing horizontally (11) head (5) a rail, slopes a side face (α) <78°. Having a set overall width (B) the base of a rail (7), concerning a vertical average axis (13) webs (6), thus is asymmetrically located concerning the head of a rail (5), that the part of width (B1) (7) rails from a working rail, at least, is more than sole in 1.2 times, than a rail part (B2) from the check rail.

EFFECT: creation of groove rail which is simple in manufacturing and could perceive basically horizontally operating transverse forces at reliable, in particular, elastic resting on the base or on structural components interacting with it.
