Title: composite girder which uses a filled steel pipe as a web member and ties and connects with a steel wire
Inventor: JUNG HA DONG
IPC: E01D2/00
Filed: 2017-05-19
Abstract: The present invention relates to producing a composite girder by using a concrete-filled steel pipe as a web member. According to the related art, top and bottom chord materials are fixed with a vertical steel pipe. As a result, load concentration occurs at a fixing point during bridge sagging attributable to common load placement on a bridge. In addition, cracking occurs due to a horizontal shear force, rotational displacement, and pulling force concentration. According to the related art, a complicated point-stop member is used for pulling force prevention, which results in an increase in production cost. Accordingly, simpler production is required. According to the present invention, a top chord material, a bottom chord material, and a filled steel pipe web are connected with a steel wire, and thus problems can be addressed with regard to the production and use of a complicated point-stop member. Work on steel wire tension can be performed with a steel wire and a head alone, and thus the material cost is economical. A hinge structure prevents cracking and the like. In addition, assembly-based production and steel wire coupling simplify the work.
