摘要

The utility model relates to the field of restoration of bridge structures, in particular, it can be used in the construction of temporary (including short-term) overpass bridges, on bypasses of destroyed, under construction and reconstructed permanent bridges. of the frame support of the REM-500 overpass, allowing to change its length in order to ensure the transportation of the assembled superstructure of the REM-500 overpass with two attached crossbars of the frame support of the REM-500 overpass, within the dimensions of the approximation of buildings operating on the rail and road. due to the fact that the sliding crossbar of the REM-500 overpass support consists of three parts, it differs in that the middle (central) part is connected to the superstructure, and the two side parts are movable, connected to the central part by four sliding prismatic tongue-and-groove joints of the “dovetail” type tail", and the side parts are connected to each other by two screw rods with drive units.
