Demountable bridge componet connecting system - with detachable bolting media in dovetail guideways in upper and lower chords

摘要

The bridge, which can be dismantled, comprises a main girder and ramps, assembled from centre components, and with side-walling units connected to a roadway plate, which forms an upper chord, and to a lower chord. The sidewalls (8) of each centre component (1) and ramp component have wedge-shaped deformations (11a) on their narrow sides, and are form-lock connected by a dovetail-type guideway in the upper and lower chord (7, 10) or in an intermediate element of detachable bolting media (13) in the guideways, pref. in the form of clamp elements of the wedge type which can be inserted between the sidewalls and a wall in the guideways. The individual components can be easily transported, and quickly and easily assembled and taken apart.
