Ultra-light composite beam bridge and construction method thereof
The invention discloses an ultra-light composite beam bridge which comprises a bridge deck structure, a profiled steel sheet, a reinforcing mesh, a handrail, an anchoring structure, a steel beam and a shear-resistant stud structure. The bridge deck structure comprises a UHPC layer and an asphalt concrete pavement layer. The profiled steel sheet is arranged below the bridge deck structure; the reinforcing mesh comprises an upper-layer reinforcing mesh and a lower-layer reinforcing mesh; the handrail and anchoring structure comprises an anti-collision handrail, a connecting steel plate and an embedded anchor bolt; the embedded anchor bolts are respectively connected with the connecting steel plate and the lower-layer reinforcing mesh; the steel beam and shear-resistant toggle pin structure comprises a transverse steel beam, a longitudinal steel beam and shear-resistant toggle pins. The transverse steel beams are connected with the longitudinal steel beams; the tops of the transverse steel beams and the longitudinal steel beams are connected with the profiled steel sheet through the shear-resistant studs. The invention further provides a construction method of the ultra-light composite beam bridge. In the construction process, the bridge deck slab does not need to be poured through a formwork, construction procedures are saved, stiffening ribs and transverse supports do not need to be additionally arranged at the lower steel beam web, and the rigidity requirement of the lower steel beam web of the composite beam bridge can be met.
本发明公开了一种超轻型组合梁桥，其包括桥面结构、压型钢板、钢筋网、栏杆及锚固结构、钢梁及抗剪栓钉结构；桥面结构包括UHPC层和沥青混凝土铺装层；压型钢板置于桥面结构下；钢筋网包括上层钢筋网和下层钢筋网；栏杆及锚固结构包括防撞栏杆、连接钢板、预埋锚栓；预埋锚栓分别与连接钢板、下层钢筋网连接；钢梁及抗剪栓钉结构包括横向钢梁、纵向钢梁、抗剪栓钉；横向钢梁与纵向钢梁连接；抗剪栓钉将横向钢梁、纵向钢梁的顶部与压型钢板连接。本发明还提供一种超轻型组合梁桥的施工方法。本发明在施工过程中无需采用支模浇筑桥面板，节省了施工工序，以及无需在下部钢梁腹板处加设加劲肋及横向支撑，就能满足组合梁桥下部钢梁腹板刚度要求。
