A novel aspect girder bridge structure

The present invention relates to several structural bridge between the longitudinal beams, a novel aspect main truss deck beams, longitudinal beams and beams, constitute a continuous flat planar pilot pilot section, a longitudinal flat between several levels of pilot section section with a top surface, a bottom surface coupled to the longitudinal struts disposed, level with the longitudinal coupling bracket pilot in a horizontal plane. Longitudinal coupling strut by a diagonal strut is connected to several root horizontal struts, the longitudinal struts configured. Each strut disposed within a flat plane with the longitudinal struts on one end side is connected to the cross beam, connected by one end to the level of the pilot Pilot level, also serves as a longitudinal beam coupled to the bracket rungs; longitudinal and diagonal strut connected to the bottom surface of the top surface of the struts of the side member, connected to the bottom surface of the flat plate and the longitudinal node associated the stringer subjected to axial force by the longitudinal strut is coupled to the truss frame is transmitted, reduce the axial force stringer bear, greatly reduces the outer surface of the beam bending moment. The present invention eliminates the use of telescopic longitudinal beams, the train runs to meet the requirements of a smooth line.
