Abstract:
Intended is to provide dislocation preventing means of a simple structure, which
can give a deck plate a resisting section against all dead/live loads over the
entire length of a bridge and which can ensure the prevention of dislocation from
concrete. A dislocation preventing bolt (9) includes a screw portion (91) having
a male thread, a taper portion (92) continuing to the screw portion, and a column
portion (93) continuing to the taper portion. A longitudinal rib composite
floor panel (100) includes a main beam (1), a cross beam (2) jointed to the main
beam (1), a deck plate (4) jointed on its lower face side to those beams, a longitudinal
rib (3) jointed to the upper face side of the deck plate (4), a concrete (7) placed
on the upper face of the deck plate (4), and a pavement (5) placed on the upper face
of the concrete (7). The longitudinal rib (3) has a plurality of through holes
(31), into which the dislocation preventing bolt (9) is inserted, and this dislocation
preventing bolt (9) is so fixed through a washer (98) by a nut (99) that it may not
fall out.
