FIELD: construction, road engineering. ^ SUBSTANCE: invention relates to a rail track. In a rail track from concrete boards (1) with rails (2) to direct a rail rolling stock, for instance, railway or tram lines, rails (2) are sunk accordingly into a slot of the board (1) and are laid in an elastic shell (3). Rails (2) have a head (7), a web (8) and a foot (9). Minimum width (B) of the slot exceeds the maximum width (b) of the rail foot (9). Concrete boards (1) are finished elements, which have positioning elements and fixing elements at the ends. Concrete boards (1) are rigidly connected to each other. Rails (2) are made as longer than the board (1) and are pressed into the elastic shell (3) of several boards (1). The method to manufacture a rail track from concrete boards (1) with rails (2) consists in the fact that boards (1) are made with a slot and afterwards mounted into a rail track. Then rails (2) are pressed into the elastic shell (3) of several serially arranged boards (1). ^ EFFECT: development of a reliable and quick mounting rail track with simple and identical structural elements for movement of a rail rolling stock. ^ 27 cl, 8 dwg |
