Abstract

The invention relates to a truss girder, particularly adapted to form a transom in a traffic gantry, where the truss girder is formed with triangular, quadrangular or polygonal shaped cross sectional area, produced of a material suitable for extrusion, and comprising at least an upper chord and a lower chord interconnected by means of inclined braces, and where the distances between the corners of the truss work girder are large, the units forming the truss girder, such as the chords, are fabricated separately and thereupon fixed together along their corner edges. Said units forming the chord are provided with parallel, outwards projecting fins or projections extending along the entire length of said unit, and that the inclined brace is extruded, given a shape which is complementary the shape of the space between said fins or projections, and that the inclined brace and said unit is fixed together by means of suitable clips or clamps pressed over the inclined brace and is snapped on to said fins or projections. The publication relates also to a method for assembling a truss girder having triangular, quadrangular or polygonal shaped cross sectional shape.
