摘要
The present invention relates to a magnetic jig for installing a foundation bolt of a girder for the construction of a bridge cantilever bracket and a method for manufacturing a girder using the jig, the present invention, while an installation groove is formed on an upper side of the girder and the foundation bolt is installed from the installation groove. Main jig that is fixed and arranged to protrude for a certain length, is installed on the upper surface of the girder mold, and the main jig is supported and fixed on one side, and the other side of the sub jig is fixed to the upper surface of the girder mold through a magnetic body through a magnetic connecting plate. By including the magnetic fixation means to be installed, it can be easily and accurately arranged by placing the concrete on the upper surface of the girder mold using the magnetic force, and before placing the concrete for the foundation bolt for fixing the one end of the bracket for the cantilever during the manufacture of the girder. Through this, it is possible to improve the workability of the production of the girder for the construction of the cantilever, and at the same time to further improve the productivity of the girder. The purpose is to separate and reuse the structure except the basic bolt.
