Joint between steel pipe and concrete chord member of Steel truss hybrid girder and steel pipe truss hybrid girder using the same

摘要

The present invention relates to a steel pipe-concrete composite girder constructed in a truss form using a steel pipe as a member and using concrete as a top chord and a bottom chord. The present invention relates to a steel pipe of a composite girder and a composite girder using a composite composite girder using the steel pipe as a composite member that can reduce the man-hour of synthesizing work and improve work efficiency and enhance the composite effect at these joints. . The composite connecting material according to the preferred embodiment of the present invention is a rectangular tube formed with a plurality of through-hole insert holes in a steel pipe truss composite girder having a multi-member structure consisting of a steel pipe and an upper chord and a lower chord composed of concrete, forming a box-shaped or I-shaped cross section. Shape fixing unit; And columnar first and second protrusions extending at a predetermined angle to correspond to the coupling angle of the steel pipe at the upper or lower part of the fixing unit, and used to connect the steel pipe and the upper chord and the steel pipe and the lower chord to each other. It features.
