Description

Segmental prefabrication assembly bridge steel member Technical Field The utility model relates to the technical field of prefabricated assembled bridges, in particular to a segmental prefabricated assembled bridge steel member. Background The segment prefabrication and assembly bridge is a bridge structure built by adopting prefabrication technology, and bridge segments (segments) of the bridge structure are manufactured in advance in factories and then assembled and assembled on construction sites, so that the construction time can be remarkably shortened, wherein cross beams and longitudinal beams are main bearing members of the bridge and are used for supporting bridge decks and rib plates. The cross beams are generally positioned below the deck slab and distributed along the length of the bridge, and the longitudinal beams are perpendicular to the cross beams and positioned at the center or at two sides of the deck slab. At present, in the use process of the segmental prefabrication assembly bridge steel member in the prior art, as most of the joints between the existing prefabrication cross beams and longitudinal beams are not provided with positioning structures, the difficulty is high during installation and butt joint, the situation of offset is easy to occur, and the transverse supporting capacity of the existing prefabrication longitudinal beams is weak, the stability of the whole bridge can be possibly affected, so that the segmental prefabrication assembly bridge steel member is needed to solve the problems.
