GIRDER FOR RAHMEM STRUCTURE USING SIDE WALL WITH VERTICAL TENDON AND THE CONSTRUCTION METHOD THEREFOR

摘要

The present invention relates to a Rahmen structure using a vertical tendon member and a construction method thereof capable of constructing a precast Rahmen structure by sequentially constructing a bottom plate, both walls, and a girder for a Rahmen structure after excavation of the ground by a cut and cover method. The girder for a Rahmen structure comprises: a horizontal beam having vertical tendon holes in both ends respectively; a lower end flange to form a lower plate in the end of the girder for a Rahmen structure; and an upper center flange to form an upper plate of the girder for a Rahmen structure. A bending negative moment occurs in the center by a vertical tendon member mounted on the upper surface of a horizontal beam after tension as passing through a vertical tendon hole of the horizontal beam while the horizontal beam is supported by the upper surface of both walls.
