Problems solved by technology

[0003] However, the existing truss bridges that use steel plates to form a four-sided section require a very complicated manufacturing process, since it is necessary to cut the steel plate, install reinforcement materials inside the section, weld each side, connect members, manufacture gusset plates, and process the ends of the braces. Difficult to manufacture, resulting in increased man-hours, increased manufacturing costs, and reduced economics, making it difficult to take advantage of the excellent structure of the truss bridge

Abstract

The present invention relates to a truss structure having an open-section upper chord member adapted to economise on steel materials and to improve the efficiency of truss bridge construction, by constructing truss bridges by using a truss structure for supporting truss bridges, wherein the open-section upper chord member of the truss structure is constituted in the shape of an upward-opening letter "U" so as to allow filling with concrete, and a steel material which is provided inside the open-section upper chord member is in tension. The present invention also relates to a method for producing the truss structure having the open-section upper chord member and to a truss bridge using the truss structure having the open-section upper chord member and also to a method for constructing the same.

Description

technical field [0001] The present invention relates to a truss bridge, more specifically, to a truss structure with an open section chord and a manufacturing method thereof, and a truss bridge using a truss structure with an open section chord and a construction method thereof. A truss structure in which the upper chords of the truss structure supporting the truss bridge are formed into a U-shape with the upper part opened, filled with concrete, and tensioned by steel placed inside the upper chords of the open section. Construction of the truss bridge, thereby saving steel materials and improving the constructability of the truss bridge. Background technique [0002] Generally, the truss bridge is a bridge form suitable for medium and long spans of 50-200M, and it is a structural form with extremely high cross-sectional efficiency where all components mainly resist axial forces. [0003] However, the existing truss bridges that use steel plates to form a four-sided cross-s...
