Combined steel box beam bridge with transverse ribs
The invention provides a combined steel box beam bridge with transverse ribs. The combined steel box beam bridge comprises a channel steel box beam and a concrete bridge deck slab, and is characterized in that multiple groups of transverse ribs are arranged on the channel steel box beam in the longitudinal direction; each group of transverse ribs comprises an internal stay bar transverse rib and external support arm transverse ribs arranged on the two sides of the internal stay bar transverse rib; the concrete bridge deck slab is partitioned and prefabricated to be supported by top plates and the transverse ribs of the channel steel box beam, and wet-joints are poured on site. According to the structural form, the steel transverse ribs support and stiffen the bridge deck slab, and the bridge deck slab is a forward-direction bearing plate, so that the stress performance of the structure is improved, the setting of the transverse prestress of the bridge deck slab is avoided, and the complexity of the structural construction is reduced; the combined steel box beam bridge has higher popularization value on the aspects of applicability, economical property, processing quality, construction project time limit and the like, and has pioneering significance on future similar projects.
