CONSTRUCTION OF THE LIGHT-SIZED FLOATING STRUCTURE OF THE METAL RIDGE REM-500

摘要

A useful model relates to the construction of rail collapsible bridges on railways. It can be used in the construction of, for example, a collapsible metal rack REM-500, railway bridge overpass IMZh-500 and other railway collapsible bridges.;The technical task of the utility model is to reduce the overall dimensions, reduce weight, simplify the installation and dismantling of the overpass, as well as ensure a long period of maintenance-free operation and storage.;The technical problem is solved due to the fact that the design of the lightweight folding span of the metallic overpass differs from the design taken for the prototype in that in the lightweight structure of the span structure the main beams in the form of welded I-beams made of steel are replaced by box-section beams made of a composite material (for example, fiberglass). The lightweight folding span structure is constructed of two parts, the elements of the span structure are interconnected by a sprinter and horizontal ties - hinged joints. Sprengel and horizontal ties are made of steel.
