A preventing construction from upseting an upper plate of highway ramp

摘要

The present invention relates to a fall prevention facility of a ramp bridge top plate at an elevated elevation of a three-dimensional intersection, and in a support structure of a ramp bridge top plate in which a bridge device is installed on an upper surface of a bridge and a box girder of a bridge top plate is placed on the bridge device. The reinforcing plate flange (1) is fixed to the side wall of the box girder (16), and the fall prevention frame (5) is installed in the upper part of the pier so as to be located outside the reinforcing plate flange (1), and the reinforcing plate flange (1) The fixing plate 2 fixed to the side wall of the box girder 16 is formed vertically, and the vertical reinforcement plate 3 is fixed to be perpendicular to the outer surface of the fixing plate 2, the vertical reinforcement plate 3 The upper surface is fixed to the vertical reinforcing plate (3) and one end of the engaging box portion (4) is fixed to the outer surface of the fixing plate (2), the fall support frame (5) is the lower plate (7) upper surface The cover plate (9) And the cover plate 9 fixes the internal reinforcing plate 8 vertically therein, and the lower plate 7 has a plurality of bolt holes 6 formed thereon and fixed anchor bolts 11 installed on the piers. The bolt portion of the combination is fixed, the upper surface of the cover plate 9 is characterized in that the locking step 10 is formed toward the reinforcing plate flange (1).
